[0001] This utility model relates to the field of pollution interception technology for hydropower station dams, and in particular to a pollution interception and cleaning device for hydropower station dams. Background Technology

[0002] A hydroelectric dam is a giant hydraulic engineering structure that converts the energy of water flow into electrical energy. It spans a river, forms a reservoir by intercepting water flow, stores water, and then uses the water level difference to drive a turbine generator to produce clean electricity.

[0003] A search revealed a reservoir dam debris interception device disclosed in Chinese Patent Publication No. CN216379438U. This device, through a drive mechanism, can flip the filter plate when there are many pollutants on its surface, allowing the pollutants to be flushed into the interior of the filter frame, ensuring the normal use of the filter plate. The installation and transmission mechanisms simplify the installation and disassembly process of the filter frame, enabling the removal and cleaning of pollutants that have flowed into the filter frame after the filter plate is flipped.

[0004] However, the cleaning structure of the pollution interception device of the reservoir dam is relatively simple, and the pollutants collected inside the filter frame are accompanied by a large amount of water, making it inconvenient for subsequent staff to remove the pollutants from inside the filter frame. Therefore, a new pollution interception and cleaning device for hydropower station dams is proposed. Summary of the Invention The technical problem to be solved by this utility model is to provide a debris interception and cleaning device for hydropower station dams, which can precisely control the raising and lowering of baffles and debris interception plates, thereby filtering impurities in the water through the debris interception plates; cleaning the debris interception holes inside the debris interception plates to prevent them from being blocked by impurities or silt; collecting and sorting the intercepted impurities, and dehydrating them by squeezing, so that the collected impurities can be collected and cleaned by subsequent staff.

[0022] Example 1: like Figure 1-5 In the present invention, a device for intercepting and cleaning debris at a hydropower station dam includes a dam body 1, wherein a drive structure 2 and a debris interception and cleaning structure 3 are provided on the outside of the dam body 1. The aforementioned dirt-blocking and cleaning structure 3 includes an equipment box 301, in which a drive motor 302 is fixedly installed. The output end of the drive motor 302 is connected to a bevel gear 303, which meshes with a threaded cone gear 304 for transmission. A cleaning basket 305 is sleeved on the outside of the threaded cone gear 304. A filter plate 306 is fixed inside the cleaning basket 305, and a cleaning strip 307 is provided on the back. An electric telescopic rod 308 is installed on the outside of the equipment box 301, and its output end is connected to the cleaning plate 309.

[0023] In a preferred embodiment, the drive structure 2 includes a mounting block 201, a hydraulic telescopic rod 202 fixed inside the mounting block 201, a top plate 203 connected to the top of the hydraulic telescopic rod 202, a baffle 204 and a debris-blocking plate 205 installed at the bottom of the top plate 203, and a plurality of holes for debris blocking are provided on the debris-blocking plate 205.

[0024] In the preferred embodiment, there are four mounting blocks 201, symmetrically distributed on the outer wall of the dam body 1. The hydraulic telescopic rods 202 in the four mounting blocks 201 drive two top plates 203 in pairs. One top plate 203 is equipped with a baffle 204, and the other top plate 203 is equipped with a debris barrier 205.

[0025] In a preferred embodiment, the top of the device box 301 is fixedly connected to the top plate 203 of the drive structure 2, the bottom of the threaded tapered rod 304 penetrates through the device box 301 and extends to the outside, and its top is linked with the drive motor 302 through the bevel gear rod 303.

[0026] In the preferred embodiment, the bottom of the equipment box 301 is fixed with a guide rod, and the two sides of the cleaning basket 305 are respectively threadedly connected to the threaded tapered rod 304 and slidably connected to the guide rod through connecting plates, forming a stable lifting structure.

[0027] In a preferred embodiment, the filter plate 306 includes three independent filter layers, which are respectively installed on the left and right sides and the back of the cleaning basket 305, and the front of the cleaning basket 305 is hinged to the box door.

[0028] In a preferred embodiment, there are multiple cleaning strips 307, the shape of which is adapted to the dirt-blocking holes of the dirt-blocking plate 205, the electric telescopic rod 308 passes through the top plate 203 and is connected to the cleaning plate 309, the surface of the cleaning plate 309 is covered with a cleaning brush, and it fits tightly against the outer wall of the cleaning basket 305.

[0029] In a preferred embodiment, the drive motor 302 is a waterproof motor, and its housing is sealed to the outer wall of the equipment box 301.

[0030] In a preferred embodiment, the surfaces of the bevel rod 303 and the threaded bevel rod 304 are treated with anti-corrosion measures.

[0031] In a preferred embodiment, the cross-sectional shape of the cleaning plate 309 matches the curvature of the outer wall of the cleaning basket 305, forming a full-contact cleaning structure.

[0032] Example 2: like Figure 4 The device is equipped with an external control panel for operation. Two hydraulic telescopic rods 202 raise one of the top plates 203, causing the baffle 204 to move upward. This moves the water flow towards the baffle plate 205, which filters impurities from the water. After a period of use, the two hydraulic telescopic rods 202 lower the baffle 204, leaving the impurities filtered by the baffle plate 205 between it and the baffle plate. Then, the drive motor 302 is turned on to rotate the bevel gear rod 303. The rotation of the bevel gear rod 303 drives the threaded cone rod 304 to rotate, which, in conjunction with the connecting plate, moves the cleaning basket 305 horizontally upward along the guide rod.

[0033] Example 3: like Figure 3During the upward movement of the cleaning basket 305, the cleaning strip 307 moves upward along the sludge trap holes of the baffle plate 205 to unclog and clean the sludge trap holes, preventing them from being blocked by impurities or silt. The rising of the cleaning basket 305 collects the intercepted impurities into its interior. Then, the other two hydraulic telescopic rods 202 are controlled to move the other top plate 203 and the baffle plate 205 upward. After moving to the appropriate position, the electric telescopic rod 308 is opened to move the cleaning plate 309 downward, pressing the impurities collected inside the cleaning basket 305 to remove internal moisture. The cleaning brush on the outer surface of the cleaning plate 309 can also clean the filter plate 306 inside the cleaning basket 305. After completion, the door can be opened to remove the impurities after moisture removal, making it convenient for cleaning personnel to collect and process them.

[0034] Example 4: like Figure 2 In the above, drive motor 302 is a forward and reverse motor. A forward and reverse motor is a motor that can achieve forward and reverse rotation. The working principle of a forward and reverse motor is based on changing the phase sequence of the motor power supply to change the direction of rotation. In a three-phase asynchronous motor, the direction of rotation of the motor can be changed by swapping any two phases. This operation is called commutation, which allows the motor to run in different directions as needed.

[0035] Example 5: like Figure 1-5 The working principle of this utility model is as follows: First, the baffle 204 is raised by the setting of the drive structure 2, so that the water flows through the debris barrier 205 and the debris barrier 205 intercepts and filters the impurities. Then control the baffle 204 to descend, so that the intercepted impurities are located between the baffle 205 and the baffle 204; Then turn on the drive motor 302 to drive the cleaning basket 305 to rise, collect the impurities through the cleaning basket 305, and clean the dirt-blocking hole through the cleaning strip 307; Finally, opening the electric telescopic rod 308 will lower the cleaning plate 309, thereby dehydrating the impurities inside the cleaning basket 305, making it easier for staff to collect and clean it later.

[0036] The beneficial effects of this utility model are: precise control of the raising and lowering of the baffle and the debris barrier, thereby filtering impurities in the water through the debris barrier; cleaning the debris barrier holes inside the debris barrier to prevent them from being blocked by impurities or silt; collecting and sorting the intercepted impurities, and dehydrating them by squeezing, making it easier for subsequent staff to collect and clean the impurities.
