The motor 41 can rotate in both directions based on an electric signal.

The construction of the drain plug device of the present invention will be described below.

In the drain plug device of the present embodiment, the operation device 5 is assembled at the factory to the following states.
First, the lock mechanism 45 is attached to the lower portion 6c of the casing. Next, the lower part 6c of the casing is attached to the middle part 6b of the casing from below. At this time, the rod portion 46 is inserted into a through hole formed below the wall portion 9 that separates the detour 8 and the mechanism chamber 7, and the end portion is arranged in the mechanism chamber 7.
Next, the operation shaft 21 is arranged in the central portion 6b of the casing. At this time, the operation shaft 21 is inserted into a through hole formed above the wall portion 9 from the inside of the mechanism chamber 7 in a state where the grip portion 30 is not attached, and the end portion thereof is above the upper end of the casing middle portion 6b. Located in.
Here, packings are arranged at the through openings formed above and below the wall portion 9, and when each packing comes into contact with the rod portion 46 and the operation shaft 21, the watertight state is established. Therefore, the drainage flowing in the detour 8 does not flow into the mechanism room 7.
Next, the grip portion 30 is inserted into the operation shaft 21 and attached. The through hole formed above the wall portion 9 has substantially the same diameter as the outer diameter of the operation shaft 21 and is smaller than the grip portion 30, but in the present invention, the grip portion 30 is the operation shaft 21. Since it is a separate member from the above, it is possible to attach the grip portion 30 after arranging the operation shaft 21. Further, a substantially cross-shaped rib 22 is formed on the operation shaft 21, and an insertion port 31 having substantially the same shape is also formed on the grip portion 30. Therefore, when the grip portion 30 attached to the operation shaft 21 is rotated, the operation shaft 21 also rotates.
Next, the motion transmitting portion 35 is attached so as to cover the driven portion 23. At this time, since the motion transmission unit 35 has a substantially semicircular shape in a plan view, it can be easily attached without performing the work of inserting the operation shaft 21. Then, the lid 13 is attached to the central portion 6b of the casing using a screw (not shown). At this time, since the motion transmitting portion 35 is sandwiched between the casing middle portion 6b and the lid body 13, it can be displaced only in the vertical direction.
This completes the assembly of the operating device 5 in the factory.
Next, at the site, the upper portion 6a of the casing is attached to the opening formed at the edge of the tank body 1. Then, the middle portion 6b of the casing is attached from below the upper portion 6a of the casing, and the upper portion 6a of the casing and the lower portion 6c of the casing are connected by a C-shaped band.
Next, after fitting the button portion 20 to the operation shaft 21, the outer tube is attached to the pipe on the downstream side of the drain plug 2, the valve shaft 40 is fixed to the wire receiver 3, and the valve body 4 is attached to the valve shaft 40. By fitting, the construction of the drain plug device of this embodiment is completed.

Next, the operation of the drain plug device of the present embodiment will be described.

First, the operation by the manual operation unit 51 will be described in detail.
As shown in FIG. 1, when the valve body 4 is in the lowered state and the drain port is closed, an operation on the manual operation unit 51, that is, a direct push operation on the button unit 20 is applied. The button portion 20 is displaced downward, and the operation shaft 21 is lowered. At this time, the inner wire slides in the outer tube toward the valve body 4, pushes up the valve body 4 from below, and the valve body 4 rises. Further, as the operation shaft 21 is lowered, the rod portion 46 is pushed down to operate the lock mechanism 45, and the raised state of the valve body 4 is maintained.
At this time, as shown in FIG. 8, the motion transmission unit 35 remains at the height position before the push operation is applied to the button unit 20, and only the button unit 20 and the driven unit 23 are lowered.

When a direct pushing operation is further applied to the button portion 20 in the raised state of the valve body 4, the gears in the lock mechanism 45 are disengaged, so that the inner wire slides toward the operating device 5. The valve body 4 is lowered by this. Further, as the valve body 4 is lowered, the button portion 20 and the operation shaft 21 are raised and returned to their original positions.

As described above, when the operation by the manual operation unit 51 is performed, all the members constituting the electric operation unit 52 including the operation transmission unit 35 do not operate at all.

Next, the operation by the electric operation unit 52 will be described in detail.
When the valve body 4 is in the lowered state and the drain port is closed, if an operation is applied to an electric button portion (not shown), the motor 41 operates based on the electric signal and the pinion gear 42 rotates. As a result, the rack gear 36 is displaced downward, and the motion transmission unit 35 is lowered. At this time, as shown in FIG. 9, the contact portion 37 comes into contact with the step portion 24 and pushes down the driven portion 23 (operation shaft 21) to transmit the operation of the electric operation portion 52 to the manual operation portion 51. Then, the valve body 4 is raised by lowering the manual operation unit 51, and the raised state of the valve body 4 is maintained by the lock mechanism 45.
After that, when it is detected by a sensor (not shown) that the operation shaft 21 has been lowered to a predetermined position, the motor 41 rotates in the reverse direction, and the motion transmission unit 35 returns to the original position. At this time, as shown in FIG. 8, the positional relationship of each member of the operating device 5 is exactly the same as when the valve body 4 is raised by the manual operating unit 51.

When an operation is further applied to the electric button in the raised state of the valve body 4, the motor 41 is driven again, and the operation transmission unit 35 pushes down the operation shaft 21 to release the meshing of the gear in the lock mechanism 45. The valve body 4 descends. At this time, as shown in FIG. 1, the positional relationship of each member of the operating device 5 is exactly the same as when the valve body 4 is lowered by the operation of the manual operating unit 51.

As described above, in the present invention, the manual operation unit 51 has a structure linked to the operation of the electric operation unit 52. Then, when an operation is applied to the electric operation unit 52, the operation transmission unit 35 returns to the original position shown in FIGS. 1 and 8 each time the motor 41 is driven. Even when the operation is performed, the positional relationship of each member when the valve body 4 is raised or lowered is always a predetermined arrangement. Therefore, it is possible to operate the manual operation unit 51 after the operation of the electric operation unit 52, or to operate the electric operation unit 52 after the operation of the manual operation unit 51.

On the other hand, if the motor 41 is stopped while the motion transmission unit 35 is lowered as shown in FIG. 9 due to biting of sand or dust or damage to the sensor, the driven unit 23 and the operation transmission unit 35 interfere with each other. Therefore, the operation by the manual operation unit 51 cannot be performed. In this case, the interlocking of the manual operation unit 51 and the electric operation unit 52 can be released by operating the release mechanism as follows.
First, in the state of FIG. 9, the button portion 20 is removed from the operating device 5. When removing the suction cup, the suction cup can be attracted to the button portion 20 and pulled up, or the suction cup can be removed by inserting a stick or the like into the gap between the button portion 20 and the casing 6.
Next, the grip portion 30 attached to the operation shaft 21 is gripped, and the operation shaft 21 is rotated. At this time, from the state of FIG. 10A, as shown in FIG. 10B, the ridge portion 26 gets over the locking portion 39, and the interlocking state of the manual operation unit 51 and the electric operation unit 52 is released. .. That is, by rotating the operation shaft 21, the step portion 24 is arranged directly under the slit 38, and the groove portion 25 is arranged directly under the contact portion 37, so that the driven portion 23 and the motion transmitting portion 35 are arranged with each other. It is placed in a position that does not interfere. As a result, as shown in FIGS. 11 and 12, the operation shaft 21 can be returned to the original position, and thereafter, the valve body 4 can be raised and lowered only by the manual operation unit 51. By rotating the operation shaft 21, the magnet arranged inside the operation shaft 21 is located outside the detection range of the sensor, and the electric operation unit 52 becomes inoperable.
Further, as shown in FIG. 10A, when the manual operation unit 51 is in an interlocking state with the electric operation unit 52, the ridge portion 26 is arranged in the storage unit 10 and only in the direction of releasing the interlocking. It can be rotated. Therefore, it is impossible for the operator to rotate the operation shaft 21 in the wrong direction. On the other hand, in the state where the manual operation unit 51 and the electric operation unit 52 are released from interlocking, the ridge portion 26 interferes with the contact portion 37 of the motion transmission unit 35, so that the interlocking release state shown in FIG. 10B is further released. It cannot be rotated in the same direction. Therefore, the interlocking of the manual operation unit 51 and the electric operation unit 52 can be surely released. Here, in a state where the interlocking of the manual operation unit 51 and the electric operation unit 52 is released, the operation shaft 21 is rotated in the opposite direction (rotation to the right) so that the manual operation unit 51 is interlocked with the electric operation unit 52 again. It is possible. At this time, the ridge portion 26 gets over the locking portion 39, is arranged in the storage portion 10, and the manual operation portion 51 is in the interlocking state again. That is, the release mechanism can rotate only in the direction in which the manual operation unit 51 is interlocked with the electric operation unit 52, and is in the interlocking state again when the interlocking is released. It is equipped with a rotation range regulation mechanism so that it can rotate only in the direction. That is, the rotation direction is regulated according to the released state, and the rotatable angle is regulated at the time of rotation. Therefore, it is possible to prevent failure of release and damage to the member due to rotation in an erroneous direction or excessive rotation.

The drain plug device in the present invention is easy to release the interlocking operation, and unlike the conventional drain plug device, when the electric operation unit 52 breaks down, the apron portion of the tank body 1 is removed for repair. The work can be omitted. Therefore, even a general user can perform the interlocking release operation.

The disconnection between the manual operation unit 51 and the electric operation unit 52 is a temporary measure, and it is finally necessary to replace the electric operation unit 52. Even at that time, if the grip portion 30 is removable, the work of replacing the grip portion 30 becomes easy. Further, when the inside of the manual operation portion 51 is clogged, the inside can be cleaned by removing the button portion 20 and the grip portion 30.

Further, in the drain plug device, a small space is formed between the button portion 20 and the casing upper portion 6a, and drainage may flow in from the space, but the inflowing drainage passes through the casing upper portion 6a. , Passes through the detour 8 and passes through the outside of the locking mechanism 45, and is discharged to the downstream side. That is, drainage does not flow into the mechanism chamber 7 due to the packing arranged on the wall portion 9. Therefore, it is possible to prevent the drain plug device from being damaged due to the inflow of drainage.

The drain plug device in the present invention is described above, but the present invention is not limited to the shape of the above embodiment, and various modifications can be made without departing from the gist of the invention. For example, in the above embodiment, the operation mechanism has a manual operation unit and an electric operation unit, but may have only two or more manual operation units. Further, it may have a total of three or more manual operation units and electric operation units.
Further, in the above embodiment, the release mechanism is arranged in the manual operation unit, but the release mechanism may be provided in a place different from the manual operation unit.
