AI Technical Summary
In the existing hydropower station silt system, the range of silt for buckets is relatively wide, which makes it difficult to concentrate on silt suction, affecting the suction efficiency of the silt pump.
A hydropower station silting system is designed, including a bucket, a collection bucket, a silting hole and a silting pump. The bucket can rotate relative to the push part and rise through the lifting part. The sludge is concentrated into the silt hole, and the silt pump is concentrated through the silt pipe. The collection bucket provides greater space for silt to concentrate and the baffle prevents silt from leaking out.
Through this system, sludge can be centrally pumped, improving the suction efficiency of the silt pump and ensuring normal drainage operations at the gate of the hydropower station.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydropower stations, in particular to a silt cleaning system for a hydropower station. Background Art
[0002] In the prior art, a silt pump is generally used to suck the silt at the gate of a hydropower station to ensure normal drainage operation at the gate. At the same time, to improve the silt cleaning effect, a bucket is provided in the prior art to scoop up the silt. However, the scooping range of the bucket is relatively wide, and it is inconvenient to centrally suck the silt, which affects the suction efficiency of the silt pump. Summary of the Utility Model
[0003] Aiming at the above problems, the utility model provides a silt cleaning system for a hydropower station, which is convenient to centrally suck the silt in the bucket and improves the suction efficiency of the silt pump.
[0004] The technical solution of the utility model is as follows:
[0005] A silt cleaning system for a hydropower station includes a gate plate, a pushing member, a mounting frame, a bucket, a silt pump and a lifting member. The pushing member is arranged at the bottom of one side of the gate plate. One end of the back side of the bucket is rotatably connected to the pushing member. The mounting frame is arranged at the top of the gate plate on the same side as the pushing member. The lifting member and the silt pump are arranged on the mounting frame. The lifting member is connected to the end of the bucket far from the pushing member. A silt cleaning hole is arranged at the bottom of the end of the back side of the bucket close to the pushing member. A silt cleaning pipe is arranged between the silt pump and the silt cleaning hole.
[0006] In a further technical solution, a collecting hopper integrally formed with the bucket is arranged at the end of the bucket connected to the pushing member, and the collecting hopper is inclined relative to the bucket.
[0007] In a further technical solution, the collecting hopper is inclined relative to the bucket at an angle of 160-170 degrees.
[0008] In a further technical solution, an arc transition is arranged between the collecting hopper and the bucket.
[0009] In a further technical solution, a baffle is arranged at the front side of the collecting hopper.
[0010] In a further technical solution, the pushing member is a first hydraulic rod.
[0011] In a further technical solution, the lifting member includes a second hydraulic rod and a rope. A connecting hole is arranged at the end of the bucket far from the pushing member. The second hydraulic rod is vertically arranged at the bottom of the mounting frame. Two ends of the rope are respectively connected to the end of the second hydraulic rod and the connecting hole.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The pusher can push the bucket to scoop up silt. Since the bucket can rotate relative to the pusher, after scooping, the bucket can be lifted by the lifting part away from the end connected to the pusher, causing the silt in the bucket to concentrate towards the silt cleaning hole, facilitating the centralized suction of silt by the silt cleaning pump through the silt cleaning pipe and improving the suction efficiency of the silt cleaning pump.
[0014] 2. An additional collecting hopper is provided, which can provide a larger space for the concentrated silt, facilitating more silt to concentrate near the silt cleaning hole. A baffle is arranged on the front side of the collecting hopper to prevent the silt from leaking out from the front side of the collecting hopper when there is a large amount of silt.
[0015] 3. A rope is set up and connected to the bucket for lifting. The structure is simple, the relative positions of the lifting part and the collecting hopper are more flexible, and it is convenient for installation. Description of the Drawings

[0020] The embodiments of the present invention will be further described below with reference to the drawings.
[0021] Embodiment:
[0022] As Figure 1 - Figure 2 shown, a silt cleaning system for a hydropower station includes a gate plate 10, a pusher 20, a mounting frame 30, a bucket 40, a silt cleaning pump 50, and a lifting part. The pusher 20 can be a first hydraulic rod and is arranged at the bottom on the side of the gate plate 10 that needs silt cleaning. One end of the back side of the bucket 40 is rotatably connected to the pusher 20. The mounting frame 30 is arranged on the top of the gate plate 10, on the same side as the pusher 20. The lifting part and the silt cleaning pump 50 are arranged on the mounting frame 30, and the lifting part is connected to the end of the bucket 40 away from the pusher 20; a silt cleaning hole 41 is provided at the bottom of the back side of the bucket 40 near the pusher 20, and a silt cleaning pipe 51 is provided between the silt cleaning pump 50 and the silt cleaning hole 41.
[0023] The working principle of the above technical solution is as follows:
[0024] The first hydraulic rod is initially in a contracted state. When using this system for dredging, the first hydraulic rod can be extended to push the bucket 40 to scoop up silt. The lifting part can lift the bucket 40 away from one end of the pushing part 20. Since the pushing part 20 is rotatably connected to the end of the bucket 40, the bucket 40 can rotate relative to the pushing part 20, causing the silt in the bucket 40 to concentrate on the side where the dredging hole 41 is located. At this time, the dredging pump 50 can be started to centrally suck the silt through the dredging pipe 51.
[0025] In another embodiment, as Figure 2 shown, a collecting hopper 70 integrally formed with the bucket 40 is provided at one end of the bucket 40 connected to the pushing part 20. The collecting hopper 70 is inclined relative to the bucket 40 at an angle of 160 - 170 degrees; for the convenience of the smooth rotation of the bucket 40, an arc transition is provided between the collecting hopper 70 and the bucket 40; a baffle 71 is provided on the front side of the collecting hopper 70. The additional setting of the collecting hopper 70 can provide a larger space for the concentrated silt, facilitating more silt to concentrate near the dredging hole 41. The baffle 71 is provided on the front side of the collecting hopper 70 to prevent the silt from leaking out from the front side of the collecting hopper 70 when there is more silt.
[0026] In another embodiment, as Figure 1 - 2 shown, the lifting part includes a second hydraulic rod 61 and a rope 62. A connecting hole 42 is provided at one end of the bucket 40 away from the pushing part 20. The second hydraulic rod 61 is vertically arranged at the bottom of the mounting frame 30. Both ends of the rope 62 are respectively connected to the end of the second hydraulic rod 61 and the connecting hole 42. The setting of the rope 62 for lifting the bucket 40 has a simple structure, and the relative positions of the lifting part and the collecting hopper 70 are more flexible, facilitating installation.
[0027] The above embodiments only represent the specific implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
