Description

Technical Field

[0001] This invention belongs to the field of ecological dam technology, specifically relating to a sand-based leak-proof dam. Background Technology

[0002] In river ecological restoration, wetland protection, and river-lake connectivity projects, a key focus in this field is how to achieve river level regulation, baseflow maintenance, and water exchange between rivers and wetlands without completely blocking water flow. Traditional water conservancy projects often employ rigid structures such as concrete weirs, masonry weirs, or earth-rock dams to raise water levels and control flow. While these weirs are structurally stable and effectively block water, their impermeable nature completely isolates water between upstream and downstream sections of the river or between the river and lateral wetlands. This prevents the natural discharge of baseflow, interrupts wetland water supply, disrupts aquatic organism migration pathways and water nutrient exchange processes, and ultimately affects the ecological cycle function of the entire river-wetland system.

[0003] Therefore, how to provide a sand-based leak-proof embankment that promotes ecological circulation is an urgent problem to be solved in this field. Summary of the Invention

[0004] The main objective of this invention is to provide a sand-based leak-proof weir to solve the aforementioned technical problems. This device utilizes a sand base layer to achieve water flow interconnection between the river channel and wetland on both sides of the entire sand-based leak-proof weir, realizing ecological water circulation between the river channel and the wetland.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sand-based leak-proof embankment includes a sand base layer, a protective layer, wooden piles, and a concrete layer. The sand base layer is provided on the upper end of the concrete layer, and the protective layer is provided on top of the sand base layer. Wooden piles are inserted into the sand base layer, with the bottom end of the wooden piles fixed to the concrete layer and the top end of the wooden piles abutting against the bottom end of the protective layer. Multiple water-passing mechanisms are also fixed on the concrete layer.

[0006] Furthermore, the water-passing mechanism includes a water-passing housing. The interior of the water-passing housing is divided into a drive chamber and a working chamber by a partition. The drive chamber is equipped with a drive mechanism one and two drive mechanisms two. An intermediate connecting plate is fixedly connected between the two drive mechanisms two. The drive mechanism one is connected to a lifting block located at the top of the intermediate connecting plate. The bottom ends of each drive mechanism two abut against a sliding block. The two sliding blocks are slidably connected between the intermediate connecting plate and the inner wall of the water-passing housing. The sides of the sliding blocks are connected to the inner wall of the water-passing housing through multiple elastic connectors. The water-passing housing is also provided with a water-permeable hole one and a water-permeable hole two.

[0007] Furthermore, the second drive mechanism includes a motor, a connecting rod, and a cam. The motor is fixed to the top of the partition. The output end of the motor passes through the partition and is connected to one end of the connecting rod. The other end of the connecting rod passes through the intermediate connecting plate and the cam in sequence and is rotatably connected to the bottom of the inner wall of the water-passing shell.

[0008] Furthermore, the drive mechanism includes a second motor, a transmission belt, a transmission wheel, and threaded columns. Two threaded columns are rotatably connected between the partition and the intermediate connecting plate. Lifting blocks are rotatably connected to the two threaded columns via threads. The second motor is fixedly connected to the top of the partition. The output end of the second motor passes through the partition and is rotatably connected to one end of a threaded column. Transmission wheels are fixedly connected to the top of each of the two threaded columns. The two ends of the transmission belt are respectively connected to the two transmission wheels.

[0009] Furthermore, the elastic connector includes a telescopic cylinder and a spring. One end of the telescopic cylinder is connected to one side of the sliding block, and the other end of the telescopic cylinder is connected to the inner wall of the water-passing housing. A spring is sleeved on each telescopic cylinder. One end of the spring is connected to the sliding block, and the other end is connected to the inner wall of the water-passing housing.

[0010] Furthermore, the sliding block is provided with multiple water-permeable holes.

[0011] Furthermore, the lifting block is provided with a second water-permeable hole.

[0012] Furthermore, the sand base layer is wrapped with a mesh screen. Furthermore, the wooden stakes undergo carbonization treatment.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a sand base layer to achieve water flow interconnection between the river channel and wetland on both sides of the entire sand-based leaky weir, thereby realizing the ecological water cycle between the river channel and the wetland. The water-passing mechanism in this invention can improve the water-passing effect by driving the movement of the lifting block during the river flood season, and can also improve the water resource circulation on both sides of the entire sand-based leaky weir by controlling the movement of the sliding block.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-2 As shown, the present invention provides a sand-based leak-proof embankment, including a sand base layer 1, a protective layer 2, wooden piles 3, and a concrete layer 4. The top of the concrete layer 4 is provided with the sand base layer 1, the top of the sand base layer 1 is provided with the protective layer 2, wooden piles 3 are inserted into the sand base layer 1, the bottom end of the wooden piles 3 is fixed to the concrete layer 4, the top end of the wooden piles 3 abuts against the bottom end of the protective layer 2, and multiple water-passing mechanisms are also fixed on the concrete layer 4.

[0020] In this embodiment, the water-passing mechanism includes a water-passing housing 5. The water-passing housing 5 is divided into a drive chamber 5.1 and a working chamber 5.2 by a partition. The drive chamber 5.1 is provided with a drive mechanism one and two drive mechanisms two. An intermediate connecting plate 6 is fixedly connected between the two drive mechanisms two. The drive mechanism one is connected to a lifting block 16 located at the top of the intermediate connecting plate 6. The bottom ends of the drive mechanisms two abut against sliding blocks 8. The two sliding blocks 8 are slidably connected between the intermediate connecting plate 6 and the inner wall of the water-passing housing 5. The sides of the sliding blocks 8 are connected to the inner wall of the water-passing housing 5 by multiple elastic connectors. The water-passing housing 5 is also provided with a water-permeable hole one 7 and a water-permeable hole two 13. The inner wall of the water-passing housing 5 is provided with grooves corresponding to the two sliding blocks 8, and rubber gaskets are laid in the grooves to improve the sealing effect and prevent a large amount of water from entering the water-passing housing. A rubber gasket is provided between the water-passing housing 5 and the lifting block 16 to improve the sealing effect and prevent a large amount of water from entering the water-passing housing.

[0021] In this embodiment, the second driving mechanism includes a motor 11, a connecting rod 10, and a cam 9. The motor 11 is fixed to the top of the partition. The output end of the motor 11 passes through the partition and is connected to one end of the connecting rod 10. The other end of the connecting rod 10 passes through the intermediate connecting plate 6 and the cam 9 in sequence and is rotatably connected to the bottom of the inner wall of the water-passing shell 5. The motor 11 can drive the cam 9 to rotate through the connecting rod 10, thereby pushing the sliding block 8 to move, so as to realize the overlap or offset of the water passage hole 8.1 and the water permeable hole 7.

[0022] In this embodiment, the drive mechanism includes a second motor 12, a transmission belt 14, a transmission wheel, and threaded posts 15. Two threaded posts 15 are rotatably connected between the partition and the intermediate connecting plate 6. Lifting blocks 16 are rotatably connected to the two threaded posts 15 by threads. The second motor 12 is fixedly connected to the top of the partition. The output end of the second motor 12 passes through the partition and is rotatably connected to one end of a threaded post 15. Transmission wheels are fixedly connected to the top of each of the two threaded posts 15. The two ends of the transmission belt 14 are respectively connected to the two transmission wheels.

[0023] In this embodiment, the elastic connector includes a telescopic cylinder 19 and a spring 18. One end of the telescopic cylinder 19 is connected to one side of the sliding block 8, and the other end of the telescopic cylinder 19 is connected to the inner wall of the water-conducting housing 5. A spring 18 is sleeved on each telescopic cylinder 19. One end of the spring 18 is connected to the sliding block 8, and the other end is connected to the inner wall of the water-conducting housing 5. The spring 18 can pull the sliding block 8 to reset in time.

[0024] In this embodiment, the sliding block 8 is provided with a plurality of water passage holes 8.1. When the water passage hole 8.1 coincides with the water permeable hole 7, water flows through. When the water passage hole 8.1 and the water permeable hole 7 are misaligned, the water flow is blocked.

[0025] In this embodiment, the lifting block 16 is provided with a water passage hole 2 17, so that the water flow during the flood season can pass through the large-diameter water passage hole 2 17 and the water permeable hole 2 13, thereby improving the drainage effect.

[0026] In this embodiment, the sand base layer 1 is wrapped with an intercepting net to prevent the sand base layer 1 from being lost, while ensuring the flow of water on both sides.

[0027] In this embodiment, the wooden stake 3 undergoes carbonization treatment to prevent it from rotting.

[0028] Working principle: The sand base layer 1 is used to achieve water flow interconnection on both sides of the sand-based leaky weir, promoting water flow on both sides of the weir. During the flood season, it can restrain the high-peak and large-volume flood peaks in the river channel (some of which may leak into the wetlands outside the weir). A small amount of water and aquatic organisms flow to the wetlands through the sand base layer 1. During the non-flood season, when the river base flow level is higher than the wetland water level, the sand base layer 1 of the sand-based leaky weir can supplement the ecological flow to the lakes and wetlands outside the river channel; when the river base flow level is lower than the wetland water level, wetland water can supplement the river base flow through the sand base layer 1 of the sand-based leaky weir. Additionally, the cam 9 can be driven by the drive motor 11 to move the sliding block 8, so that the water passage hole 8.1 and the water permeable hole 7 can be aligned or misaligned to achieve bottom water circulation. Furthermore, the sliding block 8 can be returned to its original position by an elastic connector, thereby misaligning the water passage hole 8.1 and the water permeable hole 7. When the water passage hole 8.1 and the water permeable hole 7 are aligned, water flows through; when the water passage hole 8.1 and the water permeable hole 7 are misaligned, the water flow is blocked. During the flood season, the drive motor 12 can control the lifting and lowering of the lifting block 16. When the lifting block 16 rises, the water passage hole 17 and the water permeable hole 13 overlap, and the water flow during the flood season can circulate through the large-diameter water passage hole 17 and the water permeable hole 13, thereby improving the water flow effect.
