Description
Technical Field
[0001] This utility model relates to the field of dam cleaning technology, and in particular to a dam cleaning device for water conservancy projects. Background Technology
[0002] A dam is generally a water-retaining structure on a riverbed, mainly used to intercept rivers, form reservoirs or raise water levels, and provide conditions for power generation, flood control, irrigation, water supply, and navigation. At the same time, many floating objects may appear on the water surface and pass over the dam. These floating objects will accumulate at the dam and cause pollution to the river, so it is necessary to clean up the floating objects at the dam.
[0003] Patent publication number CN204803863U discloses a floating debris cleaning device for the intake of a water conservancy dam. The intake of the water conservancy dam is equipped with a support platform. The support platform has a hollow structure, and a metal mesh frame is vertically mounted on the bottom of the support platform. A filter screen is mounted on the outside of the metal mesh frame. One end of the filter screen is fixed to the top of the metal mesh frame, and the other end passes through the support platform via a chain. The length of the filter screen is the same as the height of the metal mesh frame. A feed inlet is located at the bottom of the support platform, and a cover plate is provided at the feed inlet. The cover plate is slidably connected to the feed inlet. A manhole is located at the top of the support platform, and a hinged manhole cover is provided at the manhole. A ladder is vertically mounted on the manhole. A rotary motor is located above the support platform, and the end of the chain is connected to the rotary motor. This device intercepts floating debris on the water surface through the filter screen, and then pulls the filter screen from the feed inlet to the support platform through the chain, thereby cleaning the floating debris from the dam. However, after the filter screen retrieves the floating debris, operators need to enter the support platform through the manhole to process the debris on the filter screen, which makes it impossible to remove the retrieved debris in a timely manner, thus reducing cleaning efficiency.
[0004] To address the problems existing in the above-mentioned prior art, we have designed a dam cleaning device with high cleaning efficiency. Utility Model Content
[0005] To overcome the shortcomings of existing devices where, after the filter screen retrieves floating debris, operators need to enter the support platform through a manhole to process the debris, making it difficult to remove the retrieved debris in a timely manner and reducing cleaning efficiency, the technical problem to be solved is to provide a cleaning device for dams with higher cleaning efficiency.
[0006] The technical solution is as follows: A dam cleaning device for water conservancy projects includes a support plate, a fixed frame, a reel, a pull rope, a barrier frame, square sliders, gears, racks, a support frame, a placement plate, support bars, triangular sliders, and rotating blocks. The support plate is installed on the dam. Square sliders are slidably connected to the upper part of the support plate, and barrier frames are rotatably connected between the square sliders. Fixed frames are connected to the upper part of the support plate, and reels are rotatably connected to the upper part of the fixed frames. Pull ropes are connected to the reels, and the lower parts of the pull ropes are connected to the square sliders on the same side. Gears are connected to the left side of the barrier frame, and racks are connected to the inner side of the fixed frame on the left side. The racks and gears mesh. Support frames are connected to the rear of the support plate, and support bars are connected between the support frames. Rotating blocks are rotatably connected to the right side of the support bars, and placement plates are connected between the rotating blocks. Triangular sliders are slidably connected to the left side of the support bars, and the upper sides of the triangular sliders are in contact with the placement plates.
[0007] Preferably, a water level measuring device is provided on the support plate on the left side for measuring the water level.
[0008] Preferably, each mounting bracket is equipped with a guide wheel, and the pull rope passes around the guide wheel, which is used to guide the pull rope.
[0009] Preferably, the system also includes a derailment frame, multi-stage electric push rods, and pads. Multi-stage electric push rods are connected to both sides of the barrier frame, and pads are connected to the telescopic rods of the multi-stage electric push rods. Derailment frames are connected between the pads, and the derailment frames are slidably connected to the barrier frame.
[0010] Preferably, the system also includes guide rods, springs, and buffer blocks. Guide rods are slidably connected inside the support bars, and buffer blocks are connected between the guide rods on the same support bar. Springs are fitted on the guide rods, and the two sides of the springs are connected to the support bars and buffer blocks, respectively.

Detailed Implementation
[0029] The present invention will now be described in detail with reference to the accompanying drawings.
[0030] Example 1
[0031] A dam cleaning device for water conservancy projects, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 12 The system includes a support plate 1, a fixing frame 2, a winding reel 3, a pull rope 5, a barrier frame 6, a square slider 601, a gear 8, a rack 9, a support frame 10, a shelf 11, a support bar 13, a triangular slider 14, and a rotating block 15. The support plate 1 is installed on the dam. There are two support plates 1. The left support plate 1 is equipped with a water level measuring device 101 for measuring the water level. A fixing frame 2 is connected to the upper part of each support plate 1. A winding reel 3 is rotatably connected to the upper part of each fixing frame 2. A guide wheel 4 is provided on each fixing frame 2. A pull rope 5 is connected to each winding reel 3. The pull rope 5 passes around the guide wheel 4, which guides the pull rope 5. The support plate 1... Each part is slidably connected to a square slider 601. The upper part of each square slider 601 is connected to a pull rope 5 on the same side. The barrier frame 6 is rotatably connected between two square sliders 601. The inner side of the left fixed frame 2 is connected to a rack 9. A gear 8 is connected to the left side of the barrier frame 6. The gear 8 and the rack 9 mesh. The rear part of each support plate 1 is connected to a support frame 10. There are two support bars 13 connected between two support frames 10. The right side of each support bar 13 is rotatably connected to a rotating block 15. A shelf 11 is connected between the two rotating blocks 15. Triangular sliders 14 are slidably connected to the left side of the support bars 13. The upper side of each triangular slider 14 is in contact with the shelf 11.
[0032] In use, the barrier frame 6 is first positioned in the river to intercept floating debris on the water surface. After intercepting a certain amount of debris, the reel 3 is rotated, causing the pull rope 5 to wind around it. The pull rope 5 then pulls the square slider 601 upwards. This upward movement of the square slider 601 drives the barrier frame 6 and gear 8 upwards. After moving upwards a certain distance, the gear 8 contacts the rack 9. Due to the meshing of the gear 8 and rack 9, the gear 8 rotates during its upward movement. This rotation causes the barrier frame 6 to rotate backwards, dumping the intercepted floating debris onto the placement plate 11. This allows for quick clearing of the floating debris. Then, the reel 3 is released, and the pull rope 5 is relaxed. The barrier frame 6, gear 8, and square slider 601... Under its own gravity, it resets downwards, releasing the rope 5. Due to the meshing of gear 8 and rack 9, gear 8 rotates in the opposite direction when it moves downwards. The reverse rotation of gear 8 drives the barrier 6 to rotate forward. Then, the barrier 6 falls back into the river to intercept the floating objects. The floating objects are cleared by following the above operation. When the floating objects on the placement plate 11 accumulate to a certain amount, slide the triangular slider 14 to the right. When the triangular slider 14 slides to the right, it pushes the placement plate 11 and the rotating block 15 to rotate upwards. At this time, the placement plate 11 is tilted, and the garbage on the placement plate 11 slides to the right. The garbage can be collected and processed on the right side of the placement plate 11. After processing, slide the triangular slider 14 to the left. When the triangular slider 14 resets to the left, the placement plate 11 and the rotating block 15 rotate downwards to reset.
[0033] Example 2
[0034] Based on Example 1, please refer to the following: Figures 4-6 It also includes a discharge frame 7, a multi-stage electric push rod 701 and a pad 702. The discharge frame 7 is slidably connected to the barrier frame 6. The discharge frame 7 is used to discharge the garbage on the barrier frame 6. The multi-stage electric push rod 701 is installed on both the left and right sides of the barrier frame 6. The pads 702 are all connected to the telescopic rods of the multi-stage electric push rod 701 and are all connected to the discharge frame 7.
[0035] After the barrier frame 6 rotates backward, the multi-stage electric push rod 701 is activated. The extension rod of the multi-stage electric push rod 701 extends, causing the pad 702 and the discharge frame 7 to slide outward. When the discharge frame 7 slides outward, it pushes the garbage on the barrier frame 6 backward, preventing the garbage from sticking to the barrier frame 6, thereby improving the cleaning effect. After the cleaning is completed, the extension rod of the multi-stage electric push rod 701 retracts, causing the pad 702 and the discharge frame 7 to return to their original position inward.
[0036] Please refer to the following: Figure 8 , Figure 10 and Figure 11It also includes guide rods 16, springs 17 and buffer blocks 18. There are four guide rods 16 that are slidably connected inside the support bar 13. Each guide rod 16 is fitted with a spring 17. Buffer blocks 18 are connected between the two guide rods 16 on the same support bar 13. One end of the spring 17 is connected to the support bar 13 and the other end is connected to the buffer block 18. The buffer block 18 is used to buffer the triangular slider 14.
[0037] When the triangular slider 14 slides to the right a certain distance, it will contact the buffer block 18. At this time, the spring 17 and the buffer block 18 will buffer the triangular slider 14 to prevent the triangular slider 14 from sliding too fast and causing wear, while ensuring the stability of the rotation of the shelf 11.
[0038] Please refer to the following: Figure 7 , Figure 8 and Figure 9 It also includes a connecting rod 12, a pull rod 19, and a push plate 20. The connecting rod 12 is slidably connected to the front and rear sides of the shelf 11, the pull rod 19 is connected between the right sides of the two connecting rods 12, and the push plate 20 is connected between the left sides of the two connecting rods 12. The push plate 20 is used to push the garbage on the shelf 11 down.
[0039] When the shelf 11 is rotated upward, the lever 19 is pulled to the right. The lever 19 moves to the right, which in turn moves the connecting rod 12 and the push plate 20 to the right. As the push plate 20 moves to the right, it pushes the trash on the shelf 11 to the right, which makes it easier to clean the trash on the shelf 11 and prevents the trash from sticking to the shelf 11, thus improving the cleaning effect.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
