Technical Field
[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a seepage prevention and water-stopping structure for water conservancy and hydropower engineering. Background Technology
[0002] Water conservancy and hydropower projects are projects undertaken to develop and utilize water resources. Specifically, they include water development, utilization and protection, flood control, irrigation, water supply projects, as well as the design and construction of hydraulic structures such as hydropower stations, dams, and sluice gates.
[0003] Patent publication number CN221320833U discloses a seepage-proof and water-stopping structure for water conservancy and hydropower projects, including a base. A concrete slab is fixedly connected to the upper surface of the base. A waterproof dam body is fixedly connected to the upper surface of the concrete slab. A stone slab seat is fixedly connected to the upper surface of the concrete slab. A cement layer is fixedly connected to the right side of the waterproof dam body. Equally spaced buffer springs are fixedly connected to the right side of both the cement layer and the right side of the stone slab seat. A buffer plate is fixedly connected to the right end of each buffer spring. Equally spaced pressure-reducing grooves are formed on the right side of the buffer plate. The combination of pressure-reducing holes and grooves further reduces water pressure. The seepage-proof layer increases the waterproof effect of the waterproof dam body. The waterproof layer increases the waterproof effect of the top of the device. The water-blocking plate blocks water waves. Reinforcing steel bars increase the strength of the waterproof dam body.
[0004] Although the above devices use pressure relief grooves to reduce water pressure during dam protection, simply using grooves to reduce pressure is insufficient to resist the impact of high water waves, which can easily cause water waves to impact the shore. Therefore, a seepage prevention and water-stopping structure for water conservancy and hydropower projects is proposed to solve the above problems. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a seepage-proof and water-stopping structure for water conservancy and hydropower projects.
[0006] The present invention provides a seepage prevention and water-stopping structure for water conservancy and hydropower projects, which adopts the following technical solution:
[0007] A seepage-proof and water-stopping structure for water conservancy and hydropower projects includes a waterproof dam body, the waterproof dam body having a cavity inside, and a pressure-reducing mechanism being provided on the waterproof dam body;
[0008] The pressure relief mechanism includes an impact-resistant plate disposed on one side of the waterproof dam body. A connecting plate is fixedly connected to the top of the waterproof dam body, and one end of the connecting plate is fixedly connected to one side of the impact-resistant plate. The impact-resistant plate is provided with a pressure-reducing horizontal groove and a vertical through groove. The waterproof dam body is provided with an inlet and outlet. A strip frame is fixedly connected to the outside of the waterproof dam body. A filter screen is fixedly connected to the top wall of the strip frame, and one end of the filter screen is fixedly connected to the outside of the waterproof dam body. A first pressure relief port and a second pressure relief port are provided on the top wall of the impact-resistant plate, and the second pressure relief port is located at the top of the first pressure relief port.
[0009] By adopting the above technical solution, when water waves are generated, they impact the anti-impact plate. At this time, the pressure-reducing horizontal groove buffers and reduces the pressure of the water waves. The water waves passing through the vertical through-channel directly impact the main body of the waterproof dam and are further depressurized by the strip frame. If the impact force of the water waves is too large, after the above pressure relief treatment, they will directly impact out through the first pressure relief port and hit the inner side of the connecting plate to break them up. The part that impacts upward after being broken up is finally discharged through the second pressure relief port and, under the guiding action of the bending of the top wall of the anti-impact plate, is shot back towards the river surface. The part that splashes downward falls onto the main body of the waterproof dam and slides down, thus completing the final force relief and guidance operation. Based on the above steps, the situation of water waves hitting the bank can be effectively avoided.
[0010] Preferably, the pressure-reducing horizontal grooves and vertical through grooves are arranged at equal intervals on the impact-resistant plate, and the pressure-reducing horizontal grooves and vertical through grooves are perpendicular to each other.
[0011] By adopting the above technical solution, the pressure-reducing horizontal channel can reduce pressure and block water waves from impacting the water, while the vertical channel allows water waves to pass through directly.
[0012] Preferably, the first pressure relief port is located at the top of the pressure-reducing horizontal groove and the vertical through groove, and the second pressure relief port is located at the top of the first pressure relief port.
[0013] By adopting the above technical solution, the first pressure relief port and the second pressure relief port guide and relieve the pressure of the upward-rushing water waves.
[0014] Preferably, a fixing rod is fixedly connected to the waterproof dam body, and one end of the fixing rod is fixedly connected to the impact-resistant plate.
[0015] By adopting the above technical solution, the fixing rod is fixedly connected to the lower part of the impact plate.
[0016] Preferably, the inlet and outlet ports and the strip frame are arranged at equal intervals on the waterproof dam body, and the strip frame is set on the outside of the inlet and outlet ports.
[0017] By adopting the above technical solution, external water can enter through the inlet and outlet, while water inside the cavity can also be discharged through the inlet and outlet.
[0018] Preferably, a sludge-clearing assembly is provided inside the cavity. The sludge-clearing assembly includes a nozzle pipe disposed inside the cavity. A water pump is fixedly connected inside the cavity. A connecting pipe is fixedly connected to the output end of the water pump. One end of the connecting pipe is fixedly connected to the nozzle pipe. A threaded rod is rotatably connected inside the cavity. Two guide rods are fixedly connected inside the cavity. The threaded rod is disposed between the two guide rods. Three auxiliary plates are fixedly connected to one side of the nozzle pipe. The threaded rod and the two guide rods pass through the three auxiliary plates respectively. The threaded rod is threadedly connected to the auxiliary plates. A support plate is fixedly connected inside the cavity. A motor is fixedly connected to the bottom of the support plate.
[0019] By adopting the above technical solution, the support plate provides support for the motor.
[0020] Preferably, the motor is fixedly connected to a first gear via an output shaft, and a second gear is fixedly connected to the outside of the threaded rod. The first gear is located on one side of the second gear, and the first gear meshes with the second gear.
[0021] By adopting the above technical solution, the rotation of the first gear drives the rotation of the second gear.
[0022] In summary, this utility model has the following beneficial technical effects:
[0023] 1. A seepage-proof and water-stopping structure for water conservancy and hydropower projects, through the design of a pressure-reducing mechanism, uses a pressure-reducing horizontal groove to buffer and reduce water waves, while water waves passing through the vertical groove directly impact the waterproof dam body and are further depressurized by a strip frame. If the impact force of the water waves is too large, after the above pressure relief treatment, they will directly impact out through the first pressure relief port and hit the inner side of the connecting plate to break them up. The part that impacts upward after being broken up is finally discharged through the second pressure relief port and, under the bending guidance of the top wall of the impact-resistant plate, is shot back towards the river surface, while the part that splashes downward falls onto the waterproof dam body and slides down, thus completing the final force-dissipating and guiding operation. Based on the above steps, the situation of water waves hitting the bank can be effectively avoided.
[0024] 2. A seepage-proof and water-stopping structure for water conservancy and hydropower projects, through the design of the sludge removal component, after the water pump works, the water in the cavity is extracted and sprayed upward through the nozzle pipe. At this time, the motor works to cause the nozzle pipe to move, which can cause the sprayed water flow to wash the filter screen plate at different positions, thereby cleaning and washing the filter screen plate. This can ensure the efficiency of water passage on the filter screen plate and avoid the accumulation of impurities brought by water waves on the filter screen plate that do not disappear with the water flow in time, thus causing the filter screen plate to become clogged.

Detailed Implementation
[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The present invention will be described in further detail below.
[0034] This utility model discloses a seepage-proof and water-stopping structure for water conservancy and hydropower projects. (Refer to...) Figures 1-7 It includes a waterproof dam body 1, a cavity 2 inside the waterproof dam body 1, and a pressure relief mechanism 3 on the waterproof dam body 1.
[0035] The pressure relief mechanism 3 includes an impact-resistant plate 31, which is disposed on one side of the waterproof dam body 1. A connecting plate 32 is fixedly connected to the top of the waterproof dam body 1. One end of the connecting plate 32 is fixedly connected to one side of the impact-resistant plate 31. The impact-resistant plate 31 is provided with a pressure relief horizontal groove 33 and a vertical through groove 34. The waterproof dam body 1 is provided with an inlet and outlet 35. A strip frame 36 is fixedly connected to the outside of the waterproof dam body 1. A filter screen 37 is fixedly connected to the top wall of the strip frame 36. One end of the filter screen 37 is fixedly connected to the outside of the waterproof dam body 1.
[0036] The top wall of the impact-resistant plate 31 is provided with a first pressure relief port 38 and a second pressure relief port 39. The second pressure relief port 39 is located on top of the first pressure relief port 38. When water waves are generated, the water waves impact the impact-resistant plate 31. At this time, the pressure-reducing horizontal groove 33 buffers and reduces the pressure of the water waves. The water waves after passing through the vertical through groove 34 will directly impact the waterproof dam body 1 and be further depressurized by the strip frame 36. If the impact force of the water waves is too large, after the above pressure relief treatment, they will directly impact out through the first pressure relief port 38 and hit the inner side of the connecting plate 32 and be broken up. The part that impacts upward after being broken up will finally be discharged through the second pressure relief port 39 and, under the bending and guiding action of the top wall of the impact-resistant plate 31, will be shot back towards the river surface. The part that splashes downward will fall onto the waterproof dam body 1 and slide down, thus completing the final force relief and guiding operation. Based on the above steps, the situation of water waves hitting the bank can be effectively avoided.
[0037] The pressure-reducing horizontal grooves 33 and vertical through grooves 34 are arranged at equal intervals on the impact-resistant plate 31. The pressure-reducing horizontal grooves 33 and vertical through grooves 34 are perpendicular to each other. The pressure-reducing horizontal grooves 33 can reduce pressure and block water waves when they impact, while the vertical through grooves 34 can allow water waves to pass through directly. The first pressure relief port 38 is set at the top of the pressure-reducing horizontal grooves 33 and vertical through grooves 34, and the second pressure relief port 39 is set at the top of the first pressure relief port 38. The first pressure relief port 38 and the second pressure relief port 39 guide and relieve pressure on the upward impacting water waves. A fixing rod 391 is fixedly connected to the waterproof dam body 1. One end of the fixing rod 391 is fixedly connected to the impact-resistant plate 31, and the fixing rod 391 is fixedly connected to the lower part of the impact-resistant plate 31.
[0038] The inlet and outlet 35 and the strip frame 36 are arranged at equal intervals on the waterproof dam body 1. The strip frame 36 is set outside the inlet and outlet 35. Water from the outside can enter through the inlet and outlet 35, and water in the cavity 2 can also be discharged through the inlet and outlet 35.
[0039] The cavity 2 is equipped with a dredging component 4, which includes a nozzle pipe 41. The nozzle pipe 41 is located inside the cavity 2. A water pump 42 is fixedly connected inside the cavity 2. A connecting pipe 43 is fixedly connected to the output end of the water pump 42. One end of the connecting pipe 43 is fixedly connected to the nozzle pipe 41. A threaded rod 44 is rotatably connected inside the cavity 2. Two guide rods 45 are fixedly connected inside the cavity 2. The threaded rod 44 is located between the two guide rods 45. Three auxiliary plates are fixedly connected to one side of the nozzle pipe 41. The threaded rod 44 and the two guide rods 45 pass through the three auxiliary plates respectively.
[0040] The threaded rod 44 is connected to the auxiliary plate by a thread. A support plate 46 is fixedly connected inside the cavity 2. A motor 47 is fixedly connected to the bottom of the support plate 46. The support plate 46 provides support for the motor 47. The motor 47 is fixedly connected to the first gear 48 through the output shaft. A second gear 49 is fixedly connected to the outside of the threaded rod 44. The first gear 48 is located on one side of the second gear 49 and meshes with the second gear 49. When the first gear 48 rotates, it drives the second gear 49 to rotate.
[0041] In actual operation, when this device is used, it is first connected to the power supply. During the use of this device, the impact-resistant plate 31 can directly buffer the water waves. Specifically, when the water waves hit the impact-resistant plate 31, the pressure-reducing horizontal groove 33 initially reduces the pressure of the water waves. The water flow after passing through the vertical channel 34 will fall onto the surface of the waterproof dam body 1, thereby initially dispersing and weakening the volume of the water waves to achieve further pressure relief. If the water flow after passing through the vertical channel 34 still has an upward impact tendency, this part of the water flow will first hit the strip frame 36, and the strip frame 36 will further block and reduce the pressure. In addition, a considerable amount of water will also fall into the cavity 2 through the filter screen 37 when passing through the filter screen 37, thereby reducing the pressure of the diverted water waves as well.
[0042] If the impact force of the water wave is too large, and it still has a large impact force after the above pressure relief steps, the water wave will first pass through the first pressure relief port 38 and then directly impact out through the first pressure relief port 38 and hit the inner side of the connecting plate 32 to break it up. The water wave that is splashed out after being broken up will eventually be discharged through the second pressure relief port 39 and will be shot back towards the river surface under the bending and guiding action of the top wall of the anti-impact plate 31. The water wave that splashes down will fall onto the waterproof embankment body 1 and slide down, thus completing the final force relief and guiding operation. Based on the above steps, the situation of water waves hitting the shore can be effectively avoided.
[0043] Finally, to prevent impurities caused by the water waves from accumulating on the filter screen 37 and failing to recede with the water flow in time, thus causing blockage of the filter screen 37, the water pump 42 extracts water from the cavity 2 and sprays it upward through the nozzle pipe 41. At this time, the motor 47 works and drives the first gear 48 to rotate, the first gear 48 drives the second gear 49 to rotate, the second gear 49 drives the threaded rod 44 to rotate, the threaded rod 44 drives the connected auxiliary plate to move, the auxiliary plate drives the nozzle pipe 41 to move, and the movement of the nozzle pipe 41 can cause the sprayed water to wash the filter screen 37 at different positions, thereby cleaning and rinsing the filter screen 37 and ensuring the efficiency of water passage on the filter screen 37.
[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
