Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 to fig. 4 in combination, fig. 1 is a schematic structural diagram of a voltage regulating switch device 100 according to an embodiment of the present invention under a first view angle, fig. 2 is a schematic structural diagram of the voltage regulating switch device 100 according to an embodiment of the present invention under a second view angle, fig. 3 is one of schematic structural diagrams of the voltage regulating switch device 100 according to an embodiment of the present invention under a third view angle, and fig. 4 is a schematic mating diagram of a conductive contact 181 and a switch interface 182 according to an embodiment of the present invention. The voltage regulating switch device 100 provided by the invention can be applied to a transformer, and is used for changing the connection mode of a coil winding in the transformer, so that the number of turns of a high voltage is correspondingly changed, and the purpose of regulating the voltage of a low voltage side is achieved.
In this embodiment, the voltage regulating switch may include a first driving mechanism 110, a second driving mechanism 120, a first transmission shaft 111, a second transmission shaft 121, a first limiting portion 130, a second limiting portion 140, and a first slide rail 151.
The first driving mechanism 110 is connected with the first transmission shaft 111, and is used for driving the first transmission shaft 111 to move; the second driving mechanism 120 is connected with the second transmission shaft 121 and is used for driving the second transmission shaft 121 to move; one end of the first transmission shaft 111 is connected to the second driving mechanism 120. The first limiting portion 130 is provided with a plurality of limiting holes 131. The second limiting portion 140 includes a limiting housing 141, a limiting plate 142, a limiting member 143, and an elastic connecting member 144. The limiting housing 141 is slidably connected with the first sliding rail 151, and is provided with a plurality of connecting through holes 145, and one end of the second transmission shaft 121 is inserted into one connecting through hole 145 of the plurality of connecting through holes 145 to be connected with the second limiting portion 140; the limiting plate 142 is accommodated in the limiting shell 141; the limiting piece 143 is arranged on one side of the limiting plate 142, which is close to the second transmission shaft 121, and penetrates through the limiting shell 141 to be inserted into the limiting hole 131; one end of the elastic connecting piece 144 is connected with one side of the limiting plate 142 away from the second transmission shaft 121, the other end of the elastic connecting piece 144 is connected with the inner wall of the limiting shell 141, and the second limiting portion 140 is provided with at least one conductive contact 181 for being electrically connected with at least part of the switch interfaces 182 in the plurality of switch interfaces 182.
It is understood that the transformer is pre-provided with a plurality of coil windings of the same or different parameters (a parameter is understood to be the capacity of one coil winding, the number of coil turns, etc.). Each coil winding is connected to one of the switch interfaces 182, and if the switch interface 182 is in a closed state (for example, when both contacts of the switch interface 182 are in contact with the conductive contacts 181, the switch interface 182 is in a closed state), the coil winding connected to the switch interface 182 is turned on, so that the corresponding voltage regulation is achieved. The coil windings may also be combined with each other to form different voltage regulation levels (the voltage regulation levels may also be referred to as voltage regulation levels). When voltage regulation is performed, the first driving mechanism 110 and the second driving mechanism 120 are matched with each other, and can drive the conductive contact 181 on the second limiting portion 140 to move, so that the conductive contact 181 contacts the switch interface 182, and the switch interface 182 contacting the conductive contact 181 is conducted, so that the coil winding connected with the switch interface 182 is conducted. If the conductive contact 181 is continuously moved, the conductive contact 181 is connected with other switch interfaces 182, so that the coil windings connected with other switch interfaces 182 are conducted, if the parameters of other coil windings are different from those of the coil windings before being changed, the number of turns of the high-voltage coil correspondingly changes, and the voltage output by the low-voltage side changes, so that the purpose of voltage regulation is achieved.
The specific adjustment method of the voltage adjustment may be set according to the actual situation, for example, the user may increase the output voltage, or only decrease the output voltage, etc., and the adjustment method is not limited herein.
In the present embodiment, the first driving mechanism 110 may include at least one of an electromagnetic mechanism, a pneumatic cylinder, and a hydraulic cylinder. The second drive mechanism 120 may include at least one of an electromagnetic mechanism, a pneumatic cylinder, and a hydraulic cylinder. It is understood that the first driving mechanism 110 and the second driving mechanism 120 may be the same type of driving mechanism, for example, the first driving mechanism 110 and the second driving mechanism 120 may be electromagnetic mechanisms.
Wherein the electromagnetic mechanism comprises a coil and a permanent magnet for generating a magnetic field when the electromagnetic mechanism is electrified. For example, for the first transmission shaft 111, the first transmission shaft 111 passes through the first driving mechanism 110, and a portion of the first transmission shaft 111 located in the first driving mechanism 110 may be provided with a permanent magnet, and the first driving mechanism may be configured with a coil that cooperates with the permanent magnet. When the magnetic field generated by the coil is the same as the magnetic pole of the magnetic field of the permanent magnet, a repulsive force is generated, which can be used to push the first transmission shaft 111 to move, assuming that in fig. 3, the repulsive force can be used to push the first transmission shaft 111 to move to the left. When the magnetic field generated by the coil is opposite to the magnetic pole of the magnetic field of the permanent magnet, attractive attraction force can be generated, and the attraction force can also be used for pushing the first transmission shaft 111 to move, and in fig. 3, the attraction force can be used for pushing the first transmission shaft 111 to move to the right. Similarly, a permanent magnet may be disposed on the second transmission shaft 121, and a coil matched with the permanent magnet is disposed on the second driving mechanism 120, so that the working principles of the second transmission shaft 121 and the second driving mechanism 120 are similar to those of the first transmission shaft 111 and the first driving mechanism 110, and reference may be made to descriptions of the first transmission shaft 111 and the first driving mechanism 110, which are not repeated here.
In this embodiment, the first driving mechanism 110 may drive the second driving mechanism 120 to move through the first transmission shaft 111. The second driving mechanism 120 may drive one end of the second transmission shaft 121 to extend into the connecting through hole 145 of the second limiting portion 140, so as to be connected with the second limiting portion 140. Of course, the second driving mechanism 120 may also drive the second transmission shaft 121 to disengage from the connecting through hole 145, so as to release the connection relationship between the second transmission shaft 121 and the second limiting portion 140. When the pressure needs to be regulated, the second driving mechanism 120 may drive the second transmission shaft 121 to extend into the connecting through hole 145. After the second transmission shaft 121 extends into the connecting through hole 145, the second transmission shaft 121 presses the limiting plate 142, so that the limiting piece 143 is separated from the limiting hole 131 in the first limiting portion 130, to release the locking of the first limiting portion 130 to the second limiting portion 140, and in addition, in the process that the second transmission shaft 121 presses the limiting plate 142, the elastic connecting piece 144 is pressed, so that the elastic connecting piece 144 stores elastic potential energy. After unlocking, the first driving mechanism 110 may drive the second driving mechanism 120 to move through the first transmission shaft 111, so that the second limiting portion 140 connected to the second transmission shaft 121 moves along with the movement of the second driving mechanism 120, thereby realizing the movement of the conductive contact 181. After the conductive contact 181 moves, the conductive contact 181 can be connected with other switch interfaces 182 to change the connection mode of the coils in the transformer, thereby achieving the purpose of voltage regulation.
After the conductive contacts 181 are moved, the second driving mechanism 120 may control the second transmission shaft 121 to be separated from the connection through-hole 145. When the limiting plate 142 is not extruded by the second transmission shaft 121, the elastic connecting piece 144 releases elastic potential energy, so that the limiting piece 143 is inserted into other limiting holes 131 on the first limiting part 130, that is, the first limiting piece 143 continues to lock the second limiting piece 143, and the switch interface 182 contacted with the conductive contact 181 is ensured not to easily move, so that poor contact caused by movement of the conductive contact 181 and the switch interface 182 is avoided.
Note that, the number of the limiting holes 131 and the connecting through holes 145 may be set according to practical situations, and is not particularly limited herein. In addition, the limiting holes 131 and the connecting through holes 145 may be disposed at linear intervals, and the center-to-center distances of adjacent holes of the limiting holes and the connecting through holes may be the same, so that the first limiting portion 130 and the second limiting portion 140 may be locked or unlocked conveniently.
In the present embodiment, the voltage regulating switch device 100 further includes a second sliding rail 152 for the second driving mechanism 120 to slide along the second sliding rail 152 under the driving of the first transmission shaft 111, where the second driving mechanism 120 is slidably disposed on the second sliding rail 152. It is understood that the second sliding rail 152 may be used to guide the movement direction of the second driving mechanism 120 to avoid the movement direction of the second driving mechanism 120 from being deviated, so that one end of the second transmission shaft 121 may extend into the connection through hole 145 of the second limiting portion 140. The first sliding rail 151 and the second sliding rail 152 may be disposed in parallel, and the extension lines of the first transmission shaft 111 and the second transmission shaft 121 may be perpendicular.
Optionally, the voltage regulating switching device 100 may further include a fixing plate 160. The fixing plate 160 is used for fixing and carrying the second driving mechanism 120. The second driving mechanism 120 is slidably disposed on the second sliding rail 152 through the fixing plate 160. The first transmission shaft 111 may be directly connected to the fixing plate 160 or may be directly connected to the second driving mechanism 120, so that the first driving mechanism 110 is in transmission connection with the second driving mechanism 120.
Optionally, the fixing plate 160 is provided with a clamping groove for clamping one end of the first transmission shaft 111. The first transmission shaft 111 is connected to the second driving mechanism 120 via a fixing plate 160. As can be appreciated, the clamping groove is used to clamp one end of the first transmission shaft 111 such that the first transmission shaft 111 is connected with the fixing plate 160. Of course, in other embodiments, the fastening slot may be a fastening hole, or other connecting members instead, and the connection manner of the first transmission shaft 111 and the fixing plate 160 is not particularly limited, so long as the first transmission shaft 111 and the fixing plate 160 can be connected.
Optionally, referring to fig. 4, the voltage regulating switching device 100 may further include an interface board. The interface board is provided with a plurality of switch interfaces 182 that mate with the conductive contacts 181. The number of the switch interfaces 182 and the number of the conductive contacts 181 may be set according to practical situations, and are not particularly limited herein. It will be appreciated that each switch interface 182 may act as a normally open switch that is in a closed state when both contacts of the normally open switch are in contact with the conductive contacts 181 for power conduction. Each switch interface 182 may be connected to a coil winding, so that the voltage regulation of the transformer may be achieved when the conductive state of each switch interface 182 is changed by using the conductive contact 181.
Referring to fig. 1 again, in the present embodiment, the voltage regulating switch device 100 may further include a base 170. The first driving mechanism 110, the second driving mechanism 120, the first limiting portion 130, the second limiting portion 140, and the first sliding rail 151 are all disposed on the base 170, so that the whole voltage regulating switch is convenient to be carried by using the base 170.
In this embodiment, the elastic connection member 144 may include at least one of a spring and a shrapnel. The number of the elastic connection members 144 may be one or more, and may be set according to practical situations. For example, the elastic connectors 144 are plural and are disposed on the second limiting portion 140 at intervals. One end of each elastic connecting piece 144 is connected with one side of the limiting plate 142 away from the second transmission shaft 121, and the other end is connected with the inner wall of the limiting shell 141.
The embodiment of the invention also provides a voltage regulating transformer. The step-down transformer includes a plurality of coil windings and the step-down switching device 100 in the above embodiment. Wherein at least part of the coil windings is provided with a switching interface 182, and the electrically conductive contacts 181 in the voltage regulating switching device 100 are connected to at least part of the switching interface 182. When voltage regulation is needed, the conductive contact 181 can be connected with other switch interfaces 182 by moving the conductive contact 181, so that corresponding coil windings are conducted, and the purpose of voltage regulation is achieved.
Based on the above design, the voltage regulating switch device 100 is simple in operation, and helps to simplify the voltage regulating operation. The device can realize the on/off control of the multi-stage switch through the first driving mechanism 110 and the second driving mechanism 120, thereby being beneficial to setting the number of the voltage regulation levels according to actual conditions by a user and being beneficial to flexible design of the voltage regulation levels. In addition, compared with the multistage voltage regulation grade realized by using a plurality of electromagnetic mechanisms in the prior art, the scheme can realize the multistage voltage regulation grade through two driving mechanisms, thereby being beneficial to reducing the volume of the device and reducing the cost of the device.
Referring to fig. 3, fig. 5, and fig. 6 in combination, fig. 5 is a second schematic structural diagram of the voltage regulating switch device 100 according to the embodiment of the invention under the third view angle, and fig. 6 is a third schematic structural diagram of the voltage regulating switch device 100 according to the embodiment of the invention under the third view angle. In this embodiment, when voltage adjustment is performed, if the conductive contact 181 on the second limiting portion 140 needs to be controlled to move to the left, so that the corresponding switch interface 182 on the left is in the closed state, the following matching relationship of the components may be:
in fig. 3, the limiting member 143 is clamped in the limiting hole 131 of the first limiting portion 130, and the first limiting portion 130 and the second limiting portion 140 are in a locked state; at this time, the second driving mechanism 120 may drive the second transmission shaft 121 to move downward to pass through the connection through hole 145 and press the limiting plate 142, so that the limiting piece 143 on the limiting plate 142 is separated from the limiting hole 131, so as to release the locking of the first limiting portion 130 to the second limiting portion 140 (refer to fig. 5); at the same time, the second transmission shaft 121 presses the elastic connection member 144 such that the elastic connection member 144 is compressed to store elastic potential energy; then, the first driving part drives the first transmission shaft 111 to move leftwards so as to push the second driving mechanism 120 and the second transmission shaft 121 to move leftwards. As the second transmission shaft 121 extends into the connecting through hole 145, the second limiting portion 140 is driven to slide left along the first sliding rail 151 (see fig. 6); because the distance driven by the first driving part corresponds to the position of the conductive contact 181, the position of the switch interface 182, the spacing of the limiting holes 131 and the position of the connecting through holes 145 in advance, after the second limiting part 140 slides leftwards, the conductive contact 181 contacts with other switch interfaces 182 on the left side, so that the purpose of voltage regulation is realized;
after the second limiting part 140 slides leftwards, the second driving piece pushes the second transmission shaft 121 to move upwards, so that the second transmission shaft 121 is separated from the connecting through hole 145; the elastic connecting piece 144 is not extruded by the second transmission shaft 121, and the limiting piece 143 is clamped in the limiting hole 131 under the action of the elastic connecting piece 144, so that the first limiting part 130 and the second limiting part 140 maintain locking again;
after the second transmission shaft 121 is separated from the connecting through hole 145, the first driving member can drive the first transmission shaft 111 to move to the right, and then the second driving member is utilized to enable the second transmission shaft 121 to be inserted into a new connecting through hole 145, and the above operation is repeated, so that the conductive contact can continue to move to the left.
Of course, the voltage regulating switch device 100 also has a control function for controlling the conductive contacts to move to the right, and the operation procedure is similar to the operation procedure for moving to the left, and will not be repeated here.
