Description

Technical Field

[0001] This application relates to the technical field of riverbank protection structures, and in particular to a pile-slab composite bank protection structure. Background Technology

[0002] In the fields of new energy construction projects such as water conservancy projects, waterway regulation, and ecological shoreline management, revetment structures are core facilities for resisting water erosion, preventing slope erosion and collapse, and ensuring shoreline stability. Pile-slab composite revetment structures, due to their advantages such as convenient construction, high load-bearing capacity, and adaptability to various geological conditions, are widely used in river, lake, sea, and artificial waterway slope protection projects, becoming an important technical solution for improving shoreline stability and project durability.

[0003] Existing pile-slab composite revetment structures mostly adopt a foundation configuration of pile support and panel retaining soil, directly resisting the impact of water flow and lateral pressure of soil through the panel. However, during heavy rain, the water waves in the river are large and the resulting impact force continuously erodes the soil on the beach and carries the soil into the river, resulting in serious soil erosion. It is difficult to achieve adaptive diversion and regulation of water flow and cannot effectively alleviate the risk of bank erosion and slope toe scouring caused by concentrated water flow.

[0004] Patent application number 2011205269590 discloses a pile-slab combined ecological revetment structure, including a retaining structure and a beach. The retaining structure includes multiple pile foundations, with a slab foundation spaced between every two pile foundations. A cap beam is provided on the top surface of the slab foundation and the pile foundation. A beach is provided behind the top surface of the cap beam, and the elevation of the top surface of the beach is between the lowest and highest navigable water levels.

[0005] Regarding the aforementioned technologies, the inventors believe that they suffer from drawbacks, such as difficulty in achieving adaptive diversion and control of water flow and inability to effectively mitigate the risks of bank erosion and slope toe scouring caused by concentrated water flow. Summary of the Invention

[0006] To address the aforementioned technical problems, this application provides a pile-slab combined revetment structure.

[0007] This application provides a pile-slab composite revetment structure, which adopts the following technical solution: A pile-slab combined revetment structure includes a revetment body for new energy construction projects; the revetment body for new energy construction projects has an inclined buffer surface; a return pipe is provided on the inclined buffer surface; the bottom end of the return pipe is located at the water surface, and the top end is located at the beach; multiple downwardly inclined blocking grooves are provided on the inclined buffer surface from top to bottom; the multiple blocking grooves are evenly distributed on both sides of the return pipe; multiple inlets communicating with the blocking grooves are opened on the side wall of the return pipe; a receiving unit and two sets of opening and closing units are slidably arranged along the length of the return pipe; the two sets of opening and closing units are respectively used to open and close the multiple inlets on both sides of the return pipe; a limiting unit is provided at the bottom of the return pipe; the bottom wall of the receiving unit abuts against the top wall of the limiting unit.

[0008] By adopting the above technical solution, the inclined buffer surface can directly weaken the impact intensity of water flow and waves. Multiple barrier grooves distributed from top to bottom can disperse the kinetic energy of water flow layer by layer, preventing water flow from concentrating and scouring along the slope, and can collect the mud and water washed down from the beach, preventing a large amount of mud and water from flowing into the river channel. The return pipe is connected to the barrier groove through the side wall inlet, introducing the mud and water in the barrier groove into the return pipe. The receiving unit slides upward due to the impact of the water flow, pushing the mud and water in the return pipe from the upper outlet to the beach, realizing the mud and water return effect. This effectively reduces the amount of soil loss from the beach. Two sets of opening and closing units can control the opening and closing of the inlets on both sides of the return pipe, preventing the mud and water in the barrier groove from flowing into the river channel from the return pipe when the receiving unit moves upward. The limiting unit provides stable support for the receiving unit, preventing the receiving unit from detaching from the return pipe from below.

[0009] Preferably, the opening and closing unit includes an opening and closing component and a receiving plate; the opening and closing component is slidably disposed on the main body of the revetment for the new energy building project; the opening and closing component is provided with a plurality of first through holes; after the two opening and closing components slide, the plurality of first through holes are aligned or misaligned with the plurality of barrier grooves; the receiving plate is disposed at the end of the opening and closing component away from the beach.

[0010] By adopting the above technical solution, when the water flows upward, it pushes the receiving plate to slide upward, thereby causing the first through hole on the opening and closing part to quickly misalign with the barrier groove, realizing the adaptive linkage of "water level-sliding-flow control", simplifying the water flow regulation logic, and reducing energy consumption and control complexity.

[0011] Preferably, the limiting unit further includes a limiting plate and a first elastic element; the limiting plate is rotatably mounted on the return pipe body; one end of the first elastic element is mounted on the main body of the revetment for the new energy building project; one end of the limiting plate abuts against the bottom wall of the receiving unit, and the other end abuts against the other end of the first elastic element; the first elastic element is used to push the other end of the limiting plate to move away from the beach.

[0012] By adopting the above technical solution, the first elastic element continuously pushes the other end of the limiting plate away from the beach, so that one end of the limiting plate is always in close contact with the bottom wall of the receiving unit, providing stable vertical support and positioning benchmark for the receiving unit, and preventing the receiving unit from unexpected slippage due to water flow impact or silt accumulation.

[0013] Preferably, the limiting unit further includes a connecting rod and a transmission rod; the connecting rod is rotatably mounted on the revetment body of the new energy building project; one end of the connecting rod is hinged to one end of the transmission rod, and the other end is hinged to the opening and closing member. The other end of the transmission rod is hinged to the end of the limiting plate opposite to the return pipe body.

[0014] By adopting the above technical solution, the opening and closing parts are slidably moved by the impact of water flow. The connecting rod and transmission rod convert the sliding displacement of the opening and closing parts into the rotational displacement of the limiting plate. After the limiting plate rotates, it can push the receiving unit upward, which in turn helps the water wave to push the receiving unit upward, providing sufficient thrust for the receiving unit and improving the discharge efficiency of mud and water in the return pipe.

[0015] Preferably, the receiving unit includes a receiving component and a conical component; the receiving component is slidably disposed in the return pipe body; a water inlet hole is provided on the bottom wall of the receiving component; a conical groove communicating with the water inlet hole is provided on the top wall of the receiving component; the bottom wall of the conical component has a conical surface; the conical surface is in contact with the bottom wall of the conical groove.

[0016] By adopting the above technical solution, when the water flow impacts the receiving component and moves upward, it can push the conical component upward and make part of the water flow upward through the inlet hole and the conical groove, which helps the receiving component push the mud and water in the return pipe upward, thus improving the discharge efficiency of mud and water.

[0017] Preferably, the receiving unit further includes two sliding members and two driving blocks; the two driving blocks are respectively disposed on the return pipe body; and each has an elastic degree of freedom to slide radially along the return pipe body; driving grooves communicating with the conical groove are respectively opened on both sides of the receiving member; the two sliding members are respectively slidably disposed in the two driving grooves along the radial direction of the receiving member; one end of the two sliding members is slidably connected to both sides of the conical surface; and the other end of the two sliding members abuts against the two driving blocks respectively.

[0018] By adopting the above technical solution, the upward-flowing water wave enters the inlet and impacts the bottom of the conical component, generating an upward thrust on the conical component. The sliding component is slidably connected to the conical surface at the bottom of the conical component, and the vertical limit of the drive groove prevents the conical component from moving upward. When the receiving component moves to the top outlet of the return pipe, the sliding component slides laterally and pushes the conical component upward, allowing the water to flow upward through the conical groove of the inlet hole and flush the muddy water to the outlet above the return pipe, greatly improving the muddy water discharge efficiency.

[0019] Preferably, a reset block is provided at the end of the drive block opposite to the return pipe body; a second elastic element is provided between the reset block and the return pipe body; the second elastic element is used to provide a force for the reset block to approach the receiving member.

[0020] By adopting the above technical solution, when the receiving component moves to the opening above the return pipe body, the two sides of the top wall of the receiving component press the two driving blocks toward the outside of the return pipe body. As the receiving component continues to move upward, until the sliding component moves to the driving block, the two driving blocks press the two sliding components toward the inside of the receiving component under the thrust of the two second elastic components, thereby lifting the conical component and moving the conical component away from the conical groove, thus achieving the effect of automatically opening and closing the conical groove.

[0021] Preferably, the main body of the revetment for the new energy building project is provided with two sets of anti-blocking pipes; each of the two sets of anti-blocking pipes is provided with multiple water inlets; each of the multiple water inlets is connected to the end of the multiple barrier grooves that is away from the return pipe.

[0022] By adopting the above technical solution, the upward-flowing water can enter the anti-clogging pipe body and enter the barrier tank from the inlet, and flush and stir the mud and water in the barrier tank. In the case of excessive mud and water, it can effectively prevent the blockage inside the barrier tank.

[0023] Preferably, a sliding plate is slidably disposed within each of the two anti-clogging pipe bodies; the sliding plate has multiple second through holes; after the sliding plate slides, the multiple second through holes are respectively aligned with or misaligned with the multiple water inlets.

[0024] By adopting the above technical solution, when the water wave moves upward, the sliding plate aligns the second through hole and the inlet to ensure that the water flows into the barrier channel and flushes the barrier channel; when the water wave moves downward, the sliding plate moves and misaligns the second through hole and the inlet to prevent mud and water in the barrier channel from entering the river channel through the anti-blocking pipe.

[0025] Preferably, a drive plate is provided at the end of the skateboard that is furthest from the beach.

[0026] By adopting the above technical solution, when the water wave moves upward, it can impact the drive plate and move the slide plate upward, aligning the second through hole with the water inlet; when the water wave moves downward, the slide plate and drive plate slide downward and reset under their own weight and the pressure of the water wave, misaligning the second through hole with the water inlet, thus realizing the effect of the slide plate self-adjusting according to the water wave flow.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The inclined buffer surface can directly weaken the impact intensity of water flow and waves. Multiple barrier grooves distributed from top to bottom can disperse the kinetic energy of water flow layer by layer, preventing water flow from concentrating and scouring along the slope. It can also collect the mud and water washed down from the beach, preventing a large amount of mud and water from flowing into the river channel. The return pipe is connected to the barrier groove through the side wall inlet, introducing the mud and water in the barrier groove into the return pipe. The receiving unit slides upward due to the impact of the water flow, pushing the mud and water in the return pipe from the upper outlet to the beach, realizing the mud and water return effect. It effectively reduces the amount of soil loss from the beach. Two sets of opening and closing units can control the opening and closing of the inlets on both sides of the return pipe, preventing the mud and water in the barrier groove from flowing into the river channel from the return pipe when the receiving unit moves upward. The limiting unit provides stable support for the receiving unit, preventing the receiving unit from detaching from the return pipe from below.

[0028] 2. The opening and closing parts are slidably moved by the impact of water flow. The connecting rod and transmission rod convert the sliding displacement of the opening and closing parts into the rotational displacement of the limiting plate. After the limiting plate rotates, it can push the receiving unit upward, which in turn helps the water wave to push the receiving unit upward, providing sufficient thrust for the receiving unit and improving the discharge efficiency of mud and water in the return pipe.

[0029] 3. The upward-flowing water wave enters the inlet and impacts the bottom of the conical component, generating an upward thrust on the conical component. The sliding component slides with the conical surface at the bottom of the conical component, and the vertical limit of the drive groove prevents the conical component from moving upward. When the receiving component moves to the top outlet of the return pipe, the sliding component slides laterally and pushes the conical component upward, allowing the water to flow upward through the conical groove of the inlet hole and flushing the mud and water to the outlet above the return pipe, greatly improving the discharge efficiency of the mud and water.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a pile-slab combined revetment structure. (Refer to...) Figure 1-2 The system includes a revetment body 1 for new energy building engineering, a return pipe body 2, a receiving unit 3, and a limiting unit 5. The revetment body 1 for new energy building engineering has an inclined buffer surface 11. Water waves in the river flow along the inclined buffer surface 11. The return pipe body 2 is set on the inclined buffer surface 11. The bottom opening of the return pipe body 2 is shaped like a trumpet extending outward and is located at the water surface. The top of the return pipe is located at the beach 8. The inclined buffer surface 11 is provided with a barrier groove 12 from top to bottom. Multiple barrier grooves 12 are inclined downward and evenly distributed on both sides of the return pipe body 2. Multiple inlets communicating with the barrier grooves 12 are opened on the side wall of the return pipe body 2. The receiving unit 3 and two sets of opening and closing units 4 are slidably arranged inside the return pipe body 2 along its length. The two sets of opening and closing units 4 are used to open and close multiple inlets on both sides of the return pipe body 2. A limiting unit 5 is provided at the bottom of the return pipe body 2. The bottom wall of the receiving unit 3 abuts against the top wall of the limiting unit 5.

[0038] When the water waves in the river reach the beach 8, water will accumulate at the beach. The muddy water on the beach 8 flows down the inclined buffer surface 11 of the main body of the revetment of the new energy building project along with the water flow and enters the inclined barrier trough 12. Under the guidance of the barrier trough 12, the muddy water enters the return pipe 2 from the inlet 61 and accumulates on the receiving unit 3.

[0039] As the water flows towards the beach, some of it flows into the return pipe 2, pushing the receiving unit 3 upward, which in turn pushes the mud and water in the return pipe 2 upward, finally flowing from the top opening of the return pipe 2 towards the beach. As the mud and water in the return pipe 2 move upward, the opening and closing unit 4 closes multiple inlets to prevent the mud and water from flowing back into the barrier trough 12. After the water flows back, the receiving unit 3 slides downward and resets, and the opening and closing unit 4 opens multiple inlets, allowing the mud and water in the barrier trough 12 to continue entering the return pipe 2.

[0040] A semi-circular arc plate 13 is installed above the opening of the barrier channel 12. The semi-circular arc plate 13 and the main body 1 of the revetment for new energy construction engineering form a barrier opening 14 at the opening of the barrier channel 12. The barrier opening 14 is opened upward along the inclined buffer surface 11. The barrier opening 14 can block large stones in the downward flowing mud and water and move downward with the water flow above the semi-circular arc plate 13. The mud and water enter the barrier channel 12 from the barrier opening 14, preventing large stones from blocking the barrier channel 12. When the water flows upward, the semi-circular arc plate 13 can guide the water flow and prevent the mud and water in the barrier channel 12 from being carried out.

[0041] Reference Figures 2 to 4The receiving unit 3 includes a receiving component 31, a conical component 32, two sliding components 33, and two driving blocks 34. The receiving component 31 is slidably disposed within the return pipe body 2. A water inlet hole 311 is provided on the bottom wall of the receiving component 31. A conical groove 312 communicating with the water inlet hole 311 is provided on the top wall of the receiving component 31. The bottom wall of the conical component 32 has a conical surface, which fits against the bottom wall of the conical groove 312. The two driving blocks 34 are respectively disposed on the return pipe body 2 and each has an elastic degree of freedom to slide radially along the return pipe body 2. Specifically, a reset block 341 is provided at the end of the driving block 34 facing away from the return pipe body 2. A space is provided between the reset block 341 and the return pipe body 2. There is a second elastic element 35; the second elastic element 35 is a spring; the second elastic element 35 is used to provide force for the reset block 341 to approach the receiving member 31; the receiving member 31 has a drive groove 313 communicating with the conical groove 312 on both sides; two sliding members 33 are respectively slidably disposed in the two drive grooves 313 along the radial direction of the receiving member 31; a sliding groove is respectively provided on both sides of the conical surface along its generatrix direction; one end of the two sliding members 33 is respectively located in the two sliding grooves, and is slidably connected to both sides of the conical surface through the sliding grooves; the other end of the two sliding members 33 abuts against the two drive blocks 34 respectively, and the end of the drive block 34 near the sliding member 33 has a semi-circular arc surface.

[0042] As the water flows upward, the impact force generated by the water wave pushes the receiving part 31 upward and discharges the mud and water in the return pipe 2 from above. The upward-flowing water wave enters from the inlet 61 and impacts the bottom of the conical part 32. At this time, the cylindrical part pulls the two sliding parts 33 upward, setting the sliding parts 33 into an L-shaped rod. The top wall of the sliding part 33 located in the drive groove 313 abuts against the inner wall of the drive groove 313, thereby preventing the two sliding parts 33 from moving upward. A third elastic part 36 is provided between the two sliding parts 33 and the inner walls of the two drive grooves 313. The third elastic part 36 is a spring. The two third elastic parts 36 can push the two sliding parts 33 to move outward towards the receiving part 31, preventing the conical part 32 from pulling the two sliding parts 33 to move inward towards the receiving part 31, thereby preventing the conical part 32 from moving upward under the impact of the water flow.

[0043] When the receiving part 31 is displaced to the opening above the return pipe body 2, the two sides of the top wall of the receiving part 31 abut against the semi-circular arc surfaces on the two reset blocks 341 respectively, and squeeze the two driving blocks 34 to the outside of the return pipe body 2, and compress the two second elastic members 35; as the receiving part 31 continues to move upward, until the sliding part 33 is displaced to the driving block 34, the two driving blocks 34 squeeze the two sliding parts 33 to move inward to the inside of the receiving part 31 under the thrust of the two second elastic members 35, thereby lifting the conical part 32, making the conical part 32 away from the conical groove 312, and the water flows upward through the water inlet hole 311 and the conical groove 312, and pushes the mud and water above the receiving part 31 upward, improving the discharge efficiency of the mud and water.

[0044] Since the receiving part 31 is positioned at the upper opening of the return pipe body 2, the water wave has reached its limit height when the driving block 34 pushes the sliding part 33; then the receiving part 31 moves down under its own weight, the side wall of the driving groove 313 squeezes the semi-circular surface of the driving part, and squeezes the driving part to the outside of the receiving part 31. After the receiving part 31 moves away from the driving part, the driving part is reset under the pressure of the second elastic member 35.

[0045] Reference Figure 2 and Figure 5 Each opening and closing unit 4 includes an opening and closing component 41 and a receiving plate 42. The opening and closing component 41 is slidably mounted on the revetment body 1 of the new energy building project and is located on one side of the return pipe body 2. Multiple first through holes 411 are provided on the opening and closing component 41. When the two opening and closing components 41 slide, the multiple first through holes 411 are aligned or misaligned with multiple inlets. The receiving plate 42 is located at the end of the opening and closing component 41 away from the beach 8. When the water flows upward, it pushes the two receiving plates 42, and then pushes the two opening and closing components 41 to move upward along the inclined buffer surface 11, so that the multiple first through holes 411 are misaligned with multiple inlets, blocking the barrier groove 12 from the return pipe body 2, preventing the mud and water in the barrier groove 12 from entering the return pipe body 2, and preventing the mud and water from entering the return pipe body 2 from the inlet below the receiving component 31 and being discharged into the river after the receiving component 31 slides upward.

[0046] Reference Figure 1 and Figure 2The limiting unit 5 includes a limiting plate 51, a first elastic element 52, a connecting rod 53, and a transmission rod 54. The limiting plate 51 is rotatably mounted on the return pipe body 2. One end of the first elastic element 52 is mounted on the revetment body 1 for new energy construction projects. One end of the limiting plate 51 abuts against the bottom wall of the receiving unit 3, and the other end abuts against the other end of the first elastic element 52. The first elastic element 52 is a spring, which is used to push the end of the limiting plate 51 away from the return pipe body 2 to move away from the beach 8. The connecting rod 53 is rotatably mounted on the revetment body 1 for new energy construction projects. One end of the connecting rod 53 is hinged to the opening and closing element 41, and the other end is hinged to one end of the transmission rod 54. The other end of the transmission rod 54 is hinged to the end of the limiting plate 51 away from the return pipe body 2.

[0047] When the opening / closing element 41 moves upward, one end of the pulling rod 53 rotates upward, and the other end of the pulling rod 53 pulls the end of the limiting plate 51 away from the return pipe body 2 to rotate downward through the transmission rod 54. The other end of the limiting plate 51 rotates upward, thereby assisting the water wave to push the receiving element 31; ensuring that the receiving element 31 moves up to a sufficient height to discharge the mud and water in the return pipe body 2 to the beach 8.

[0048] When the water flows back, the first elastic element 52 can press the end of the limiting plate 51 connected to the connecting rod 53 downward, ensuring that the end of the limiting plate 51 located in the return pipe body 2 remains in an upward rotating state; at the same time, the first elastic element 52 can convert the downward pushing force into an upward force through the connecting rod 53 and act on the opening and closing element 41, thereby ensuring that the opening and closing element 41 closes the inlet, preventing mud and water from entering the return pipe body 2 from the opening when the receiving element 31 slides downward and has not passed through the opening; when the receiving element 31 resets, its bottom wall abuts against the end of the limiting plate 51 located in the return pipe body 2 and presses the limiting plate 51 to reset, the other end of the limiting plate 51 rotates upward, and pulls the opening and closing element 41 downward through the connecting rod 53 to open the opening, preventing mud and water in the blocking groove 12 from entering the return pipe body 2.

[0049] Reference Figure 2 Two sets of anti-blocking pipes 6 are installed on the main body 1 of the revetment for new energy building engineering; the two sets of anti-blocking pipes 6 are distributed on both sides of the return pipe 2; multiple water inlets 61 are opened on the two sets of anti-blocking pipes 6 respectively; the multiple water inlets 61 are connected to the ends of multiple blocking grooves 12 away from the return pipe 2 respectively; sliding plates 7 are slidably installed in the two anti-blocking pipes 6 respectively; multiple second through holes 71 are opened on the sliding plates 7; after the two sliding plates 7 slide, the multiple second through holes 71 are aligned or misaligned with the multiple water inlets 61 respectively; a drive plate 72 is installed at the end of the sliding plate 7 away from the beach 8.

[0050] When the water flows upward, it pushes the two sets of drive plates 72 to move upward, which in turn pushes the two slide plates 7 to slide upward, so that the multiple second through holes 71 are aligned with the multiple water inlets 61 respectively; the water flowing into the two sets of waterproof pipes enters the barrier groove 12 from the water inlet 61, and impacts and stirs the mud and water in the barrier groove 12 to prevent the barrier groove 12 from being blocked when there is too much mud and water; when the water flows back, the two slide plates 7 and the two drive plates 72 slide downward, so that the multiple second through holes 71 are misaligned with the multiple water inlets 61 respectively, and the two sets of anti-blocking pipes 6 are separated from the multiple barrier grooves 12.

[0051] The working principle of a pile-slab composite revetment structure in this application is as follows: The river water flows upward along the inclined buffer surface 11 of the main body 1 of the revetment for new energy construction projects. The mud and water accumulated on the beach 8 flow downward with the water flow and enter the barrier groove 12 area on the inclined buffer surface 11. The semi-circular arc plate 13 above the opening of the barrier groove 12 and the main body 1 of the revetment for new energy construction projects form an upward barrier opening 14. The mud and water can enter the groove through the barrier opening 14, while large stones are blocked by the semi-circular arc plate 13 and continue to move downward with the water flow, avoiding blockage of the barrier groove 12. At the same time, the semi-circular arc plate 13 plays a guiding role for the upward flowing water waves, preventing the water waves from carrying out the mud and water already collected in the barrier groove 12.

[0052] The mud and water entering the barrier groove 12 of the return pipe body 2 flows into the pipe through the inlet on the side wall of the return pipe body 2. At this time, the limiting unit 5 at the bottom of the return pipe body 2 supports the receiving unit 3, and the mud and water accumulate on the receiving part 31 of the receiving unit 3.

[0053] When the water flows upward, it directly impacts the receiving plates 42 on both sides of the return pipe body 2, pushing the opening and closing parts 41 to slide upward along the inclined buffer surface 11; the first through hole 411 on the opening and closing parts 41 is misaligned with the inlet of the return pipe body 2, and the inlet is completely closed, blocking the communication path between the barrier groove 12 and the return pipe body 2, so as to prevent the mud and water in the return pipe body 2 from flowing back from the inlet to the barrier groove 12 or the river when the receiving unit 3 moves upward.

[0054] When the anti-blocking pipe 6 is activated, the impact force of the rising water waves in the obstruction channel 12 simultaneously pushes the drive plate 72 at the end of the anti-blocking pipe 6 upward, causing the slide plate 7 inside the anti-blocking pipe 6 to slide upward, so that the second through hole 71 on the slide plate 7 is aligned with the water inlet 61 of the anti-blocking pipe 6; the river water flows into the end of the obstruction channel 12 away from the return pipe 2 through the water inlet 61, forming an impact and stirring effect on the mud and water in the channel, preventing the mud and water from accumulating and blocking the obstruction channel 12.

[0055] When the limiting unit 5 assists the receiving unit 3 in moving upward, the opening and closing part 41 moves upward, and the connecting rod 53 pulls the outer end of the limiting plate 51 to rotate downward, while the inner end of the limiting plate 51 (located inside the return pipe 2) rotates upward, forming an upward thrust on the bottom of the receiving unit 3, which assists the water wave impact force to push the receiving unit 3 upward.

[0056] As the receiving unit 3 moves upward, the continuous upward impact of the pre-discharged mud and water waves pushes the receiving component 31 to slide along the length of the return pipe 2. The mud and water accumulated on the top of the receiving component 31 moves upward accordingly, gradually approaching the opening at the top of the return pipe 2. At the same time, some water flows through the water inlet 311 on the bottom wall of the receiving component 31 and impacts the bottom of the conical component 32. The conical component 32 tends to move upward, but the third elastic component 36 in the drive groove 313 of the receiving component 31 pushes the sliding component 33 to extend outward. One end of the sliding component 33 is inserted into the groove of the conical component 32, restricting the upward movement of the conical component 32 and ensuring the bearing effect of the receiving component 31 on the mud and water.

[0057] During the peak wave stage (when the wave reaches the limit height of beach 8 and the receiving unit 3 moves up to the top of the return pipe), when the receiving part 31 moves up to the top opening of the return pipe 2, the two sides of the top wall of the receiving part 31 abut against the semi-circular arc surface of the driving block 34, squeezing the driving block 34 to move outward of the return pipe 2 and compressing the second elastic element 35; when the receiving part 31 continues to move up to the position corresponding to the sliding part 33 and the driving block 34, the reset thrust of the second elastic element 35 pushes the driving block 34 to move inward, squeezing the sliding part 33 to slide towards the center of the receiving part 31, and the sliding part 33 pushes the conical part 32 upward; the conical groove 312 is completely connected to the water inlet 311, and a large amount of water flows upward through the water inlet 311 and the conical groove 312, forming a strong thrust on the mud and water at the top of the receiving part 31, and the mud and water are quickly discharged from the top opening of the return pipe 2 to the beach 8.

[0058] When the water wave recedes after the reset of the receiving unit 3, the impact force disappears, and the receiving unit 3 slides down along the return pipe 2 under its own gravity until the bottom re-abuts against the limiting plate 51 of the limiting unit 5, thus completing the reset.

[0059] When the inlet of the opening and closing unit 4 is opened and the mud and water collection wave returns, the impact force on the receiving plate 42 disappears. The first elastic element 52 pushes the outer end of the limiting plate 51 to rotate upward and the inner end of the limiting plate 51 to rotate downward. The connecting rod 53 pulls the opening and closing element 41 to slide downward, so that the first through hole 411 is realigned with the inlet of the return pipe body 2. The inlet is opened and the mud and water in the blocking groove 12 can flow into the return pipe body 2 again.

[0060] When the anti-blocking pipe 6 is closed, the unblocking drive plate 72 moves downward with the water wave, causing the slide plate 7 to slide down. The second through hole 71 is misaligned with the water inlet hole 311 of the anti-blocking pipe 6, and the connection path between the anti-blocking pipe 6 and the barrier groove 12 is closed, and the water flow stops entering the barrier groove 12.

[0061] As the receiving unit 3 is reset and the receiving part 31 is prepared for the next cycle, the side wall of the drive groove 313 presses against the semi-circular surface of the drive block 34, pushing the drive block 34 to move outward. The sliding part 33 extends outward again under the thrust of the third elastic part 36, and the conical part 32 falls back into the conical groove 312, re-blocking the connection path between the water inlet hole 311 and the conical groove 312, waiting for the impact force of the next rising water wave to trigger the cycle.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered by the scope of protection of this application.
