Example 1

The automatic dredging and cleaning collecting device for the sewer opening as shown in fig. 1 and 2 comprises a power assembly 100 and an actuating assembly 200. Install in the sewer mouth, the sewer mouth is provided with fence 404, and the device is used for dredging debris such as the leaf outside sewer mouth fence 404, and the power supply of use is the rainwater.

The apparatus is mounted in the borehole wall 400. The well wall 400 is the side wall of the sewer passage. A slot is dug in the well wall 400 for placement of the device.

The road teeth 600 are provided with fences 404, and water outlets 401 are opened in the fences 404. Line B shown in fig. 2 is a line at the junction of the road surface and the curb 600.

As shown in fig. 1, 2 and 4, a filter sieve 107 is disposed below the drain port 401. The filter sieve 107 has a certain inclination, that is, the upper surface has an inclined surface, and densely distributed sieve pores are opened in the filter sieve 107. The filtering screen 107 is used for guiding out the sundries such as leaves downwards, and the rainwater flows downwards into the flow channel 109 through the screen holes on the filtering screen 107. Flow channel 109 extends to tank 101 and directs rainwater to tank 101.

As shown in fig. 3, a blocking plate 1010 is further disposed in the flow passage 109, and the blocking plate 1010 is located at the liquid inlet 1013 of the water storage tank 101 in this embodiment. The blocking plate 1010 can block sundries such as sand seeds in rainwater, and the sundries are not easy to be removed by the filter sieve 107, so that the sundries such as the sand seeds are prevented from entering the water storage tank 101. As shown in fig. 2, the blocking plate 1010 is provided with a trash outlet 1091 on the outer side (i.e., the side for receiving rainwater) of the flow channel 109, and the trash outlet 1091 is used for discharging sundries such as sand seeds into the sewer.

Referring to fig. 3, the power assembly 100 includes a water storage tank 101, the water storage tank 101 includes a first chamber 1011 and a second chamber 1012, the first chamber 1011 is located above the second chamber 1012, so that rainwater in the first chamber 1011 can flow into the second chamber 1012 due to gravity. A liquid outlet 1014 is arranged between the first chamber 1011 and the second chamber 1012, a drain valve 103 is arranged at the liquid outlet 1014, and the drain valve 103 is used for controlling the opening and closing of the liquid outlet 1014. The drain valve 103 may use a structure of the prior art, such as the structure disclosed in chinese patents "CN 103306346 a" and "CN 207988063U". The upper end of the drain valve 103 is provided with a trigger button (such as "button 1" in "CN 103306346A", and also such as "full-discharge button 3" and "half-discharge button 8" in "CN 207988063U"). When the trigger button is pressed down, the outlet 1014 may be opened until the water in the first chamber 1011 is momentarily expelled into the second chamber 1012.

The power assembly 100 of this example also includes a float trigger mechanism 102. The floating ball trigger mechanism 102 is disposed in the first chamber 1011 and is used for pressing down a trigger button on the upper end of the drain valve 103.

As shown in fig. 3, the float ball triggering mechanism 102 includes a support 1024, a swing lever 1022 is rotatably disposed on the support 1024, a float ball i 1021 is disposed at one end of the swing lever 1022, a connection line 1023 is connected to the other end of the swing lever 1022, and the connection line 1023 is further connected to a trigger button at the upper end of the drain valve 103. Thus, when the liquid level in the first chamber 1011 gradually rises, the floating ball i 1021 rises, and the floating ball i 1021 drives the swing rod 1022 to rotate, so that the other end of the swing rod 1022 pulls the connection wire 1023 downwards. Until the liquid level reaches a certain height, the connection wire 1023 is enough to pull down the trigger button on the upper end of the drain valve 103, thereby triggering the drain valve 103 to open. After the drain valve 103 is opened, the water in the first chamber 1011 is instantaneously drained into the second chamber 1012.

The second chamber 1012 is provided with a floating ball II 104. When the water in the first chamber 1011 is instantaneously drained into the second chamber 1012, the floating ball II 104 is instantaneously lifted. In order to regulate the ascending path of the floating ball II 104, the floating ball II 104 is sleeved on the periphery of the guide post 106, so that the floating ball II 104 can slide on the guide post 106. The floating ball II 104 is lifted to provide power for the execution assembly 200.

As shown in fig. 4, the bottom of the second chamber 1012 (see fig. 3) is opened with an outlet 108, and the diameter of the outlet 108 is smaller than that of the outlet 1014 (see fig. 3). Thus, after the water in the first chamber 1011 is instantaneously drained into the second chamber 1012, the water is slowly drained from the drain 108 at a small speed, so that the floating ball II 104 descends and returns to the original position.

As shown in fig. 1 and 5, and in particular fig. 5, the actuating assembly 200 includes an actuating head 201, and a plurality of push rods 2011 are arranged on the actuating head 201 side by side. The execution assembly 200 further comprises a supporting plate 204, wherein a cross hinge rod I203 is arranged on the supporting plate 204, the front end of the cross hinge rod I203 is connected with the execution head 201, and the rear end of the cross hinge rod I203 is connected with a transmission line I105. When the driving wire i 105 is pulled backward, the distance between the front end and the rear end of the cross-hinged rod i 203 is increased, and the execution head 201 and the push rod 2011 are extended forward, so that a discharge port to be processed, such as a discharge fence at the side of a curb to be processed, can be extended. When the push rod 2011 penetrates through the fence, sundries such as leaves blocked outside the fence can be pushed, and at the moment, the sundries such as the leaves can easily flow into the fence hole under the impact action of water flow, so that the sundries can easily flow into a sewer, and the influence on drainage caused by the blockage outside the fence can be avoided. Due to the impact of the water flow, sundries such as leaves and the like only need to be pushed slightly, and are easy to flow into a sewer under the impact of the water flow.

The driving line I105 is connected with the floating ball II 104, and when the floating ball II 104 rises, the driving line I105 can be pulled. A roller (not shown) can be further arranged in the extending path of the transmission line I105, and the roller provides support and transmission for the transmission line I105, so that the abrasion of the transmission line I105 is reduced.

As shown in fig. 5, the actuating assembly 200 further includes a supporting frame 205, and the supporting frame 205 is mounted on the power assembly 100, specifically, is connected to the outer wall of the water storage tank 101. The support bracket 205 functions to support the pallet 204. In addition, the connection position or the shape of the supporting bracket 205 itself can be adjusted, so that the distance and height of the discharge fence from the actuating assembly 200 to the side of the road curb can be adjusted.

As shown in fig. 5, the actuator assembly 200 further includes a return spring 202, the return spring 202 being configured to return the push rod 2011. (see fig. 3) when the second chamber 1012 is drained, the float ii 104 descends and the return spring 202 returns the plunger 2011. When the actuating head 201 is pulled (indirectly pulled) by the transmission line I105, the return spring 202 accumulates energy; when drive line I105 releases actuator head 201, return spring 202 releases the stored energy, causing actuator head 201 to reset.

As shown in fig. 4, also included is a debris sweeping assembly 300. The sundries cleaning assembly 300 comprises a sundries cleaning head 301, a filter plate 302, a driving line II 303 and a cross hinged rod II 304. The filter plate 302 is disposed below the side of the filter screen 107. The filter plate 302 is used for receiving sundries such as leaves sliding down from the filter sieve 107 for cleaning. The filter plate 302 has a plurality of holes for allowing rainwater to flow down. The sundries cleaning head 301 is long and is equal to the width of the filter plate 302, the sundries cleaning head 301 is connected to the front end of the cross hinged rod II 304, the rear end of the cross hinged rod II 304 is connected with a transmission line II 303, and the other end of the transmission line II 303 is connected with the floating ball II 104 in the second chamber 1012. Rollers (not shown) can also be arranged in the extending path of the transmission line II 303, and the rollers provide support and transmission for the transmission line II 303, so that the abrasion of the transmission line II 303 is reduced. When the floating ball II 104 rises under the action of buoyancy, the cross hinge rod II 304 is pulled to be opened through the transmission line II 303, and then the sundries cleaning head 301 slides on the surface of the filter plate 302. When the sundries cleaning head 301 moves forward, sundries such as leaves on the surface of the filter plate 302 are cleaned, so that the sundries such as leaves can be collected conveniently. The other side of the filter plate 302 is further provided with a collecting basket (not shown) for collecting the sundries swept by the sundries sweeping head 301.

As shown in fig. 1 and 2, a collection basket placement groove 403 is formed by hollowing down a wall 400 of the well on the side opposite to the power module 100, with a partition 402 being left between the collection basket placement groove 403 and the sewer passage. The collecting basket is placed in the collecting basket placing groove 403, and the height of the receiving opening of the collecting basket is slightly lower than that of the filter plate 302 so as to be convenient for receiving sundries. The lower edge of the partition 402 is provided with a gap for the sundries such as leaves to pass through, so that the sundries such as leaves can enter the collecting basket. The collecting basket is convenient to be lifted out so as to dump the sundries in the collecting basket.

In this example, the implement assembly 200 and the debris cleaning assembly 300 are provided with a cross-hinged rod I203 and a cross-hinged rod II 304 respectively, and mainly function to move the implement head 201 or the debris cleaning head 301 in one direction when the cross-hinged rod I203 or the cross-hinged rod II 304 is pulled in the other direction. This has the advantage that when the float ii 104 is not pulling the actuator head 201 (most of the time this is the case), the push bar 2011 on the actuator head 201 is located in the discharge opening to be treated. That is, the push rod 2011 is located in the to-be-treated drain port instead of the to-be-treated drain port most of the time, and because cars and the like are sometimes parked outside the rain water drain port of the road teeth or passersby walks and a single vehicle runs, the push rod 2011 is located in the rain water drain port most of the time, and therefore road surface safety is facilitated. In other implementation methods, the cross hinge rod I203 and the cross hinge rod II 304 are not arranged, and the execution head 201 can be directly connected to the transmission line I105, and the sundry cleaning head 301 can be directly connected to the transmission line II 303.

Example 2

As shown in embodiment 2 of fig. 6, the main difference between this embodiment and embodiment 1 is the structure of the actuator head 201. The reference numeral 201 of the execution head in embodiment 1 is used for comparison. The embodiment is suitable for cleaning the well cover 501 of the sewer opening, and the embodiment 1 is more suitable for cleaning the fence of the sewer opening, wherein the well cover 501 is usually horizontally arranged, and the fence is usually vertically arranged.

As shown in fig. 6, the execution head 201 of this example is configured such that a plurality of blocks 2012 are provided in the execution head 201 at intervals in parallel. The plug 2012 is disposed to correspond to the leak 5011 of the manhole cover 501. After the execution head 201 moves, the blocking plate 2012 blocks a part of the leakage holes 5011; when the actuation head 201 is reset, all of the orifices 5011 are opened. Like this, can form the disturbance to the rivers through well lid 501 to debris such as the leaf in the disturbance well lid 501 outside make debris such as leaf receive the disturbance back change easily by rivers wash the well lid 501 inboard enter into the sewer.

Both embodiment 1 and embodiment 2 are used for clearing up sundries such as leaves at a road sewer opening, and the main power source used is rainwater. When a certain amount of rainwater is accumulated in the first chamber 1011, the rainwater is instantly discharged into the second chamber 1012, so that the floating ball II 104 in the second chamber 1012 floats upwards. When the floating ball II 104 floats upwards, the execution head 201 is pulled to clean.

It should be noted that the utility model can be applied to any liquid outlet that has liquid to flow in, such as the trough type male urinal in large-scale occasions like railway stations.

The main beneficial effect of above-mentioned embodiment is that, the rainwater that utilizes itself to have in the application as the power supply, need not extra energy, dredges debris such as the leaf of sewer mouth, prevents that sewer mouth from blockking up. Reduce city sanitation workman's cleaning work load, prevent to produce urban waterlogging. In addition, the pressure of the sewer discharge can be reduced by sweeping and collecting the sundries such as leaves, plastic bags and the like through the sundries sweeping component 300, which is particularly suitable for the sewer discharge system in the old urban area.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
