Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a seepage-proof lake dam for water conservancy projects. Background Technology

[0002] Lake dikes are water conservancy engineering facilities used to regulate lake water levels, ensure the safety of the surrounding areas, and provide comprehensive benefits. Their core functions are reflected in three aspects: flood control and disaster reduction, water resource allocation, and ecological and navigation improvement. Specifically, during the flood season, they intercept and store excessive floodwaters to prevent flooding disasters along the shore; during the dry season, they impound lake water to provide a stable water source for surrounding agricultural irrigation, industrial water use, and residential water supply; and at the same time, they provide a suitable living environment for the surrounding flora and fauna by stabilizing the water level.

[0003] Currently, the water-facing slopes of lake dams are constantly damp, making them highly susceptible to the growth of moss and weeds. The growth and root activity of these plants can significantly damage the slope structure, reduce the seepage prevention performance of the dam, and thus induce leakage risks. Therefore, we propose a seepage-proof lake dam for hydraulic engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a seepage-proof lake dam for water conservancy projects. It has the advantage of facilitating the removal of moss, weeds, and other plants on the water-facing slope of the lake dam, thereby effectively avoiding damage to the slope structure and ensuring the seepage-proof performance of the dam. It solves the problem that the water-facing slope of current lake dams is prone to the growth of moss, weeds, and other plants due to long-term dampness. The growth and root activity of these plants can significantly damage the slope structure, reduce the seepage-proof performance of the dam, and thus induce the risk of leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seepage-proof lake dam for water conservancy projects, comprising a dam body, a track trolley, and a track. The track is fixedly installed on the upper surface of the dam body, and the track trolley is mounted on the track. A movable rod is provided on one side of the dam body, and one end of the movable rod is fixedly connected to the upper surface of the track trolley. A guide wheel A is rotatably installed inside the movable rod near its end. A winch is rotatably installed on the outer surface of the track trolley near the movable rod. A pull rope is wound around the outer surface of the winch, and the two ends of the pull rope are fixedly connected and pass around the guide wheel A. A sliding block is fixedly installed on the outer surface of the pull rope, and the sliding block is located inside the movable rod. A collection bucket is fixedly installed on the lower surface of the sliding block, and a fixed pipe is fixedly installed inside the collection bucket. A spray head is fixedly installed on the lower surface of the fixed pipe.

[0006] Preferably, track wheels are rotatably installed inside the track trolley near the front and rear surfaces. A rotary motor B is fixedly installed on one side of the outer surface of the track trolley, and the output end of the rotary motor B is connected to the track wheels for transmission. The output end of the rotary motor B drives the track wheels to rotate, thereby driving the track trolley to move on the track.

[0007] Preferably, the track is I-shaped, and auxiliary wheels are rotatably installed on both sides of the inner wall of the track trolley near the front and rear surfaces. The auxiliary wheels contact the sides of the I-shaped track, which improves the stability of the track trolley when it moves.

[0008] Preferably, a water tank and a high-pressure water pump are fixedly installed on the upper surface of the track trolley. The end of the input pipe of the high-pressure water pump is fixedly connected to the outer surface of the water tank near the lower surface. The end of the output pipe of the high-pressure water pump is fixedly connected to a water pipe, and the end of the water pipe is fixedly connected to the outer surface of the fixed pipe. After the high-pressure water pump works, it delivers the water inside the water tank to the inside of the fixed pipe under high pressure, and then sprays it out through the spray head.

[0009] Preferably, a sliding rod is fixedly installed on the front surface of the movable rod, and slip rings are fixedly installed at equal intervals on the outer surface of the water pipe, with the slip rings slidably sleeved on the outer surface of the sliding rod. The sliding rod and slip rings can limit and guide the water pipe, so as to facilitate the movement of the water pipe.

[0010] Preferably, a rotating motor A is fixedly installed on the side of the track trolley near the winch, and the output end of the rotating motor A is connected to the winch for transmission, and the output end of the rotating motor A drives the winch to rotate.

[0011] Preferably, two guide wheels B are rotatably installed inside the moving rod near the winch, and the two guide wheels B guide the pull rope moving in and out of the moving rod.

[0012] Preferably, an elastic telescopic rod is fixedly installed at the end of the movable rod, and a support wheel is rotatably connected to the end of the elastic telescopic rod, which can support the end of the movable rod. At the same time, since the elastic telescopic rod has the function of elastic extension and contraction, the support wheel can better adapt to the water-facing slope of the dam body and uneven areas.

[0013] Preferably, a number of filter holes are evenly arranged on the outer surface of the collection hopper away from the track trolley, so that when moss, weeds and other plants are collected inside the collection hopper, the water inside the collection hopper can be drained through the filter holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a dam body, track, track trolley, moving rod, winch, pull rope, guide wheel A, sliding block, collection bucket, fixed pipe, and spray head, achieves the effect of easily removing moss, weeds, and other plants on the water-facing slope of a lake dam, thereby effectively avoiding damage to the slope structure and ensuring the seepage prevention performance of the dam. The track trolley on the track drives the moving rod to move longitudinally along the track, while the winch rotates and drives the collection bucket to move laterally along the moving rod through the pull rope and sliding block. Thus, the collection bucket can move on the water-facing slope of the dam body, and the high-pressure water sprayed from the spray head washes away the moss, impurities, and other plants on the slope, and the washed-away plants fall into the collection bucket.

[0015] 2. By setting up an elastic telescopic rod and a support wheel, this utility model can support the end of the moving rod. At the same time, because the elastic telescopic rod has the function of elastic extension and contraction, the support wheel can better adapt to the water-facing slope of the dam body and uneven areas.

[0016] 3. By setting filter holes, the water inside the collection hopper can be drained through the filter holes when plants such as moss and weeds are collected inside the collection hopper. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0020] like Figures 1-6 As shown, the present invention proposes a seepage-proof lake dam for water conservancy projects, comprising a dam body 1, a track trolley 2, and a track 3. The track trolley 2 is fixedly installed on the upper surface of the dam body 1. The track trolley 2 is mounted on the track trolley 3. Track wheels 12 are rotatably installed inside the track trolley 2 near the front and rear surfaces. The track wheels 12 are in contact with the upper surface of the track 3. A rotating motor B13 is fixedly installed on one side of the outer surface of the track trolley 2. The output end of the rotating motor B13 is connected to the track wheel 12 for transmission. The output end of the rotating motor B13 drives the track wheel 12 to rotate, thereby driving the track trolley 2 to move on the track 3. The track 3 is I-shaped. Auxiliary wheels 14 are rotatably installed on both sides of the inner wall of the track trolley 2 near the front and rear surfaces. The auxiliary wheels 14 are in contact with the sides of the I-shaped track 3, which improves the stability of the track trolley 2 when it moves.

[0021] A movable rod 4 is installed on one side of the main body 1 of the dam, and one end of the movable rod 4 is fixedly connected to the upper surface of the track trolley 2. The movable rod 4 is located on the water-facing slope of the main body 1 of the dam. The movable rod 4 is hollow inside, and its lower surface has an opening communicating with the interior along the axial direction of the movable rod 4. A guide wheel A19 is rotatably installed inside the movable rod 4 near its end. A winch 6 is rotatably installed on the outer surface of the track trolley 2 near the movable rod 4. A rotary motor A9 is fixedly installed on the side of the track trolley 2 near the winch 6, and the output end of the rotary motor A9 is connected to the winch 6. The output end of the rotary motor A9 drives the winch 6 to rotate. A pull rope 7 is wound around the outer surface of the winch 6. The two ends of the pull rope 7 are fixedly connected and the pull rope 7 passes around the guide wheel A19. Two guide wheels B21 are rotatably installed inside the moving rod 4 near the position of the winch 6. The two guide wheels B21 guide the pull rope 7 as it moves in and out of the moving rod 4. When the winch 6 rotates, the pull rope 7 is moved by the friction between its surface and the pull rope 7. A tensioning device can be set near the winch 6 to ensure that the pull rope 7 is in a taut state, so that there is enough friction between the winch 6 and the pull rope 7 to move the pull rope 7. The tensioning device is a mature existing technology, so it will not be described in detail.

[0022] A sliding block 20 is fixedly installed on the outer surface of the pull rope 7, and the sliding block 20 is located inside the moving rod 4. A collection bucket 5 is fixedly installed on the lower surface of the sliding block 20. The bottom of the sliding block 20 passes through the opening on the lower surface of the moving rod 4, so the collection bucket 5 is located below the moving rod 4. A fixed pipe 22 is fixedly installed inside the collection bucket 5. A spray head 23 is fixedly installed on the lower surface of the fixed pipe 22. A notch is provided on the lower surface of the collection bucket 5 below the spray head 23 so that the high-pressure cleaning water sprayed by the spray head 23 can contact the water-facing slope. A water tank 10 and a high-pressure water pump 1 are fixedly installed on the upper surface of the track trolley 2. 1. The end of the input pipe of the high-pressure water pump 11 is fixedly connected to the outer surface of the water tank 10 near the lower surface. The end of the output pipe of the high-pressure water pump 11 is fixedly connected to the water pipe 8, and the end of the water pipe 8 is fixedly connected to the outer surface of the fixed pipe 22. After the high-pressure water pump 11 works, it delivers the water inside the water tank 10 to the inside of the fixed pipe 22 under high pressure, and then sprays it onto the water-facing slope through the spray head 23. Several filter holes 24 are evenly arranged on the outer surface of the collection hopper 5 away from the track trolley 2. When moss and weeds are collected inside the collection hopper 5, the water inside the collection hopper 5 can be discharged through the filter holes 24.

[0023] In use, the trolley 2 on the track 3 drives the moving rod 4 to move longitudinally along the track 3, while the winch 6 rotates and drives the collection bucket 5 to move laterally along the moving rod 4 through the pull rope 7 and the sliding block 20. Thus, the collection bucket 5 can move on the water-facing slope of the dam body 1, and the high-pressure water sprayed by the spray head 23 washes away moss and other plants on the slope. The washed-away plants fall into the collection bucket 5, thereby effectively avoiding damage to the slope structure and ensuring the seepage prevention performance of the lake dam. Example 2

[0024] like Figures 1-4 As shown, the present invention proposes a seepage-proof lake dam for water conservancy projects. Compared with Embodiment 1, this embodiment further includes a sliding rod 17 fixedly installed on the front surface of the movable rod 4, and a sliding ring 18 fixedly installed at equal intervals on the outer surface of the water pipe 8. The sliding ring 18 is slidably sleeved on the outer surface of the sliding rod 17. The sliding rod 17 and the sliding ring 18 can limit and guide the water pipe 8 to facilitate its movement. An elastic telescopic rod 15 is fixedly installed at the end of the movable rod 4, and a support wheel 16 is rotatably connected to the end of the elastic telescopic rod 15.

[0025] In this embodiment, the elastic telescopic rod 15 and the support wheel 16 support the end of the moving rod 4. At the same time, since the elastic telescopic rod 15 has the function of elastic extension and contraction, the support wheel 16 can better adapt to the water-facing slope and uneven areas of the dam body 1.

[0026] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
