Description

[0001] This application claims the benefit of Chinese priority patent application 202421514200.4, filed on June 28, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of pollution control equipment technology, specifically to a river pollution control device. Background Technology

[0003] There is polluted silt in the river channel, which needs to be dredged ashore and centrally treated to ensure that the ecological environment of the reservoir area meets environmental protection standards. At present, most power plants mainly use dredging boats to clean up the floating scum, dredging the silt from the bottom of the water and then centrally treating it.

[0004] A cleaning device for a hydropower plant, with publication number CN220167025U, is disclosed. The device includes: a treatment tank; a mounting plate fixedly connected to the front of the treatment tank; a mounting box fixedly connected to the top of the mounting plate; a motor fixedly connected to the front of the inner wall of the mounting box; a rotating rod fixedly connected to one end of the motor's output shaft; and a spiral conveyor belt fixedly connected to the outside of the rotating rod.

[0005] The above-mentioned device can use a spiral conveyor belt to transport sludge. However, in actual sludge transport, the above scheme can only transport sludge on the upper surface of the filter plate. Due to the characteristics of the sludge itself, some sludge will be embedded in the filter holes of the filter plate. At this time, the spiral conveyor belt cannot remove the sludge, causing water to flow along the filter plate to the conveying mechanism, which reduces the efficiency of filtration of sludge. Utility Model Content

[0006] This utility model aims to solve the problem that some sludge in existing cleaning devices gets stuck in the filter holes of the filter plate, and the spiral conveyor belt cannot remove the sludge. It also solves the problem that water flows along the filter plate to the conveying mechanism, reducing the efficiency of sludge filtration. Therefore, a river cleaning device is proposed.

[0007] To solve the above problems, this application provides the following technical solution:

[0008] A river cleaning device includes a carrier vessel equipped with a treatment tank. A sludge pump is mounted on the top wall of the treatment tank. The input end of the sludge pump is connected to the outlet of a sludge suction pipe, and the output end of the sludge pump is connected to a discharge pipe. A support shaft is fixedly connected to the inner wall of the treatment tank, and a filter plate is rotatably connected to the outer surface of the support shaft. The discharge pipe is fixedly connected to the inner top wall of the treatment tank. The filter holes of the filter plate are located inside the treatment tank, and the lower section of the filter plate is located outside the treatment tank. A carrying mechanism is fixedly connected to one outer wall of the treatment tank, and the carrying mechanism is fixedly connected to the lower section of the filter plate. A striking mechanism is mounted on one outer wall of the treatment tank, and a sludge loading mechanism is provided on one side of the treatment tank. A drain pipe is fixedly connected to the inner wall of the treatment tank.

[0009] The left side of the fixed plate in the bearing mechanism is fixedly connected to the right side of the processing box.

The upper surface of the bearing plate is in contact with the bottom surface of the filter plate. A return spring is wound around the outer surface of the guide shaft. The upper and lower ends of the return spring are fixedly connected to the bottom surface of the bearing plate and the upper surface of the fixed plate, respectively.

[0010] The striking mechanism has a support platform fixedly connected to the outer surface of the motor body. The back of the support platform is fixedly connected to one side of the outer wall of the processing box. A rotating rod is fixedly connected to the output end of the motor body. The outer surface of the rotating rod is rotatably connected to the inner wall of the processing box. The outer surface of the rotating rod is fixedly connected to the inner wall of the two striking plates.

[0011] The sludge loading mechanism has four support legs fixedly connected to the bottom of the sludge trough, and a telescopic cylinder is installed on the inner bottom wall of the sludge trough.

[0016] The filter plate is tilted at an angle of 15° to 60° toward the sludge loading mechanism.

[0017] The outlet of the discharge pipe is located above the top filter hole of the filter plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] Example 1

[0030] Reference Figures 1-5 A river cleaning device includes a carrier vessel 1, a treatment tank 2 mounted on the upper surface of the carrier vessel 1, a sludge pump 3 mounted on the top wall of the treatment tank 2, a discharge pipe 4 fixedly connected to the output end of the sludge pump 3, a support shaft 5 fixedly connected to the inner wall of the treatment tank 2, a filter plate 6 rotatably connected to the outer surface of the support shaft 5, and the outer surface of the discharge pipe 4 fixedly connected to the inner top wall of the treatment tank 2. By using the discharge pipe 4, sludge can be transported into the interior of the carrier vessel 1. The outlet of the discharge pipe 4 is aligned with the top filter hole of the filter plate 6, allowing the sludge to be fully filtered by the filter plate 6. The filter holes of the filter plate 6 are located inside the treatment tank 2. The body of the filter plate 6 passes through a side wall window on one side of the treatment tank 2. The lower section of the filter plate 6 does not have filter holes to prevent sludge from flowing into the interior of the carrier vessel 1. The angle of the filter plate 6 tilting towards the sludge loading mechanism 9 is set to 15°~60°. When the angle is too low, below 15°, the sludge flow rate is slow and the filter holes of the filter plate 6 will be clogged by sludge. When the angle is too high, above 60°, the sludge and water flow too fast and the water cannot be fully separated from the sludge.

[0031] A support mechanism 7 is provided below the lower section of the filter plate 6. The support mechanism 7 includes a fixed plate 701. The left side of the fixed plate 701 is fixedly connected to the right side of the treatment box 2. A guide shaft 702 is slidably connected to the inner wall of the fixed plate 701. A support plate 703 is fixedly connected to the top of the guide shaft 702. The upper surface of the support plate 703 is in contact with the bottom surface of the filter plate 6. The shape of the upper surface of the support plate 703 is adapted to the bottom surface of the filter plate 6 to facilitate the support of the filter plate 6.

[0032] A return spring 704 is wound around the outer surface of the guide shaft 702. The upper and lower ends of the return spring 704 are fixedly connected to the bottom surface of the support plate 703 and the upper surface of the fixing plate 701, respectively. By using the elastic force of the return spring 704, the support plate 703 fixedly connected to the filter plate 6 can be reset, thereby preventing the filter plate 6 from being damaged by impact with the processing box 2 when it falls, and also achieving the effect of shaking the filter plate 6.

[0033] The processing box 2 is equipped with a striking mechanism 8 on its side wall. The striking mechanism 8 includes a motor body 801 and two striking plates 803. A support platform 804 is fixedly connected to the outer surface of the motor body 801. The back of the support platform 804 is fixedly connected to the side wall of the processing box 2. By using the support platform 804, the motor body 801 can be stably supported.

[0034] A rotating rod 802 is fixedly connected to the output end of the motor body 801. The outer surface of the rotating rod 802 is rotatably connected to the inner wall of the treatment box 2. The outer surface of the rotating rod 802 is fixedly connected to the inner wall of the two striking plates 803. By starting the motor body 801, the rotating rod 802 can be driven to rotate, which in turn drives the two striking plates 803 to rotate, thereby striking the filter plate 6 and causing the filter plate 6 to shake. This accelerates the filtration of sludge and allows the sludge in the openings inside the filter plate 6 to be shaken out.

[0035] A sludge loading mechanism 9 is provided on the right side of the treatment box 2. The sludge loading mechanism 9 includes a sludge trough 901. Four support feet 902 are fixedly connected to the bottom surface of the sludge trough 901. A telescopic cylinder 903 is installed on the inner bottom wall of the sludge trough 901. A support plate 904 is fixedly connected to the output end of the telescopic cylinder 903. Four moving wheels 905 are installed on the bottom surface of the support plate 904. By activating the telescopic cylinder 903 to extend and retract up and down, the support plate 904 is driven to move up and down, which in turn drives the four moving wheels 905 to move and contact the ground, thus moving the sludge trough 901 up and down.

[0036] A positioning plate 906 is fixedly connected to the left side of the sludge tank 901. The left side of the positioning plate 906 is slidably connected to the right side of the treatment box 2. By using the positioning plate 906, the position of the sludge tank 901 can be positioned, which facilitates the receiving of the sludge discharged from the filter plate 6.

[0037] A guide plate 10 is installed on the inner bottom wall of the treatment box 2. The guide plate 10 is inclined at 5°~15° to the drain pipe 11 to guide the water. The drain pipe 11 is fixedly connected to the inner wall of the front of the treatment box 2. The water inside the treatment box 2 can be easily discharged by using the drain pipe 11. A winding wheel 12 is provided on the back of the treatment box 2. A mud suction pipe 13 is wound on the outer surface of the winding wheel 12. The end of the mud suction pipe 13 near the sludge pump 3 is connected to the input end of the sludge pump 3. The end of the mud suction pipe 13 away from the sludge pump 3 is fixedly connected to the mud suction head 14. The winding wheel 12 can be used to wind and unwind the mud suction pipe 13.

[0038] Working principle: By using the take-up reel 12, the sludge suction pipe 13 with the sludge suction head 14 can be placed into the river channel of the hydropower plant. By starting the sludge pump 3, the sludge pumped out through the sludge suction pipe 13 and the sludge suction head 14 can be transported through the discharge pipe 4 to the upper surface of the filter plate 6 inside the treatment tank 2. Through the filtration of the filter plate 6, the water can be discharged downward to the top of the guide plate 10 and then guided back into the river channel by the drain pipe 11. The sludge flows into the sludge tank 901 from the opening on the right side of the treatment tank 2. By starting the motor body 801, the rotating rod 802 can be driven to rotate, which can drive the two striking plates 803 to rotate. When the striking plates 803 rotate to contact the filter plate 6, the two striking plates 803 slide rapidly on the back of the filter plate 6, causing the filter plate 6 to shake upward, thereby realizing that the two striking plates 803 strike the filter plate 6. When the striking plate 803 rotates and is not in contact with the filter plate 6, the filter plate 6 and the supporting plate 703, under the elastic force of the return spring 704, can drive the supporting plate 703 and the filter plate 6 to shake downwards. This accelerates the flow of sludge on the upper surface of the filter plate 6 and prevents sludge from clogging the filter holes inside the filter plate 6, thus reducing the water filtration efficiency in the sludge. By activating the telescopic cylinder 903, the support plate 904 can be moved, thereby driving the four moving wheels 905 to contact the ground, which allows the sludge tank 901 to be moved for subsequent treatment of the sludge inside the sludge tank 901.
