Description

Technical Field

[0001] This invention belongs to the field of fish protection technology in water conservancy engineering, specifically a fish passage facility for river dams based on ecological flow regulation and its operation method. Background Technology

[0002] A type of fish passageway, often called a "fishway" or "fish ladder," is a structure designed to help fish cross a river smoothly, preventing the dam from cutting off their habitat and breeding routes. These structures help maintain the health and stability of aquatic ecosystems, ensuring that aquatic life can continue to thrive in the presence of the dam.

[0003] The prior art document CN119824862B discloses a fish passage system and its operation method suitable for low-head overflow dams. The system includes a gate chamber, upper and lower gate heads located at both ends of the gate chamber, each gate head equipped with a gate and a guide opening. A main rotating blade is fixed inside the gate chamber near the guide opening. Reciprocating components are symmetrically arranged on both sides of the main rotating blade. Each reciprocating component includes a parallel rotating rod and a guide rod. The main rotating blade is connected to the rotating rods of the reciprocating components on both sides via a transmission assembly. A reciprocating plate is mounted on the rotating rod and slidably fitted onto the guide rod. Rotatable flipping rods are mounted on the opposite reciprocating plates on both sides, and a disturbance frame is fixed on the flipping rod. The flipping rod drives the disturbance frame to flip, switching between horizontal and vertical states. The water flow at the guide opening is converted into power, driving the reciprocating plates on the rotating rods to reciprocate linearly. The automatic flipping of the disturbance frame drives migratory fish upstream to the water area.

[0004] Although the above application can drive fish to swim to a designated location, it cannot regulate changes in water flow during this process. When the water flow speed changes, it cannot control the movement speed of the disturbance frame. Excessive water flow speed will cause the fish to swim too fast. The fish may need to exert more energy to resist the water flow, which will lead to excessive fatigue and may even cause them to be injured in the strong current, making it impossible for them to reach the target location smoothly.

[0014] Preferably, the bottom of the extrusion plate is provided with a flow propulsion assembly, the flow propulsion assembly includes an elastic tube connected to one side of the bottom of the extrusion plate, one end of the elastic tube is connected to a drainage box, one side of the drainage box is fixedly connected to one side of the top connecting plate, and a drainage port is provided at the bottom of the drainage box.

[0015] An operational method for a fish passage facility using a dam based on ecological flow regulation:

[0016] S1. Start the sonic fish attractor. The sonic fish attractor will lure the fish in the river to the gate at the upper gate. When a group of fish gathers, start the electric telescopic rod. The electric telescopic rod will move the connecting plate and the gate upward. During the upward movement of the gate, the water flow will no longer be blocked. The flowing water will carry the fish down the inclined box to the lower gate.

[0017] S2. Water flows into the gate chamber through the circular pipe at the upper gate head, and then into the circular pipe at the lower gate head. As the water flows inside the gate chamber, the thrust of the water causes the square fan roller to rotate the rotating rod. The rotating rod then rotates the stainless steel ball reciprocating screw. The stainless steel ball reciprocating screw drives the threaded plate to move back and forth along the inner wall of the inclined box, and the two threaded plates move closer to each other.

[0018] S3. The threaded plate drives the slider and the strip shell to move. The strip shell drives the slider, the vertical rod and the square roller to move closer to each other. The square roller drives the square net to move closer to each other. Under the resistance of the positioning rod and the elastic compression of the compression spring, the slider slides on the inner wall of the strip shell. At the same time, it can make the square net rotate forward and backward along the inclined plane of the inclined box. During the rotation of the square net, it can push the water flow.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention utilizes a fish-passing mechanism to activate a sonic fish attractor. The sonic fish attractor guides fish in the river to the gate at the upper sluice gate. When a group of fish gathers, an electric telescopic rod is activated. The electric telescopic rod drives the connecting plate and the gate to move upward. During the upward movement of the gate, the water flow is no longer blocked. The flowing water carries the fish down the inclined box to the lower sluice gate, allowing the fish to pass through the dam and ensuring the health and stability of the aquatic ecosystem. During this process, water flows through the circular pipe at the upper gate head into the gate chamber, and then through the gate chamber into the circular pipe at the lower gate head, causing the water to flow. As the water flows inside the gate chamber, the thrust of the water causes the square fan roller to drive the rotating rod to rotate. The rotating rod drives the stainless steel ball reciprocating screw to rotate, and the stainless steel ball reciprocating screw drives the threaded plate to move back and forth along the inner wall of the inclined box. The two threaded plates move closer to each other, and the threaded plates drive the slider and the strip shell to move. The strip shell drives the sliding strip, the vertical rod, and the square roller to move closer to each other. The square roller drives the square net to move closer to each other. Under the resistance of the positioning rod and the elastic compression of the compression spring, the sliding strip slides on the inner wall of the strip shell. At the same time, it enables the square net to rotate forward and backward along the inclined plane of the inclined box. During the rotation of the square net, it can push the water flow, effectively slowing down the water flow speed and reducing the impact of the water flow on the fish, ensuring that the fish can pass through the waterway smoothly. When the two spiral plates move away from each other, the square net is placed horizontally on top of the inclined box, blocking the water flow and indirectly creating several suitable resting areas for the fish to stay for a while and recover their energy.

[0021] This invention employs a fish-passing control mechanism. When the water flow is rapid, the water flows simultaneously at the top of the inclined box and inside the gate chamber. The rapid flow increases the rotation speed of the square fan rollers, which in turn accelerates the rotation of the square net within the control component. The rotating net pushes the water flow in the opposite direction, slowing its velocity and preventing fish from drowning or being injured due to excessive water speed. When the water flow is slow, the square fan rollers rotate less, and one end of the slowly rotating net follows the water flow, altering its direction and flow pattern. This is crucial for preventing turbulence and eddies, providing a stable water flow environment that allows fish to migrate downstream along the stable water flow. By adapting to changes in water velocity, the rotation efficiency of the square fan rollers is adjusted in real time, ensuring stable fish migration.

[0022] This invention utilizes a fish-controlling mechanism. When water flows through the gate chamber, it is stored inside a water storage tank. As the connecting plate rises, it drives the connecting rod and block to rise, which in turn drives the round rod and water storage tank to rise. During this ascent, the water storage tank comes into contact with a stationary squeezing plate. The squeezing plate slides inside the water storage tank, squeezing the water and forcing it into the elastic tube. The water then flows through the elastic tube into the drainage tank and is discharged downwards through a drain outlet. This discharges water from the upper gate head, allowing it to carry the fish down the top of the inclined tank, thus improving fish migration efficiency and preventing fish from stagnating at the upper gate head and affecting the migration of other fish. As the water storage tank moves upward, it drives the sliding plate, elastic telescopic rod, and sealing plate to move. During the movement of the sealing plate, it can contact the bottom of the gate chamber, thereby sealing the opening of the gate chamber and preventing water from flowing out through the opening of the gate chamber, which would affect the stability of the water flow driving the square fan roller to rotate, thus ensuring the stability of the device operation.

[0033] 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.

[0034] like Figures 1 to 9 As shown, the present invention provides a fish passage facility for a dam based on ecological flow regulation, including a gate chamber 1, two gate chambers 1 are provided, one end of the gate chamber 1 is fixedly connected to an upper gate head 2, and the other end of the gate chamber 1 away from the upper gate head 2 is fixedly connected to a lower gate head 3, and also includes;

[0035] The fish passage control mechanism 4 includes an electric telescopic rod 41 fixedly connected to the top of the inner wall of the upper gate head 2 and the lower gate head 3. A connecting plate 42 is fixedly connected to the top of the electric telescopic rod 41, and a gate 43 is fixedly connected to the bottom center of the connecting plate 42. An acoustic fish attractor 44 is fixedly connected to one side of the gate 43. A control component 45 is provided on the side wall of the upper gate head 2 for controlling the water flow.

[0036] The above scheme is adopted as follows: The sonic fish attractor 44 is activated. This device guides the fish in the river to the gate 43 at the upper sluice gate 2 using sound waves. When the fish gather in front of the gate 43, the electric telescopic rod 41 is activated. The electric telescopic rod 41 drives the connecting plate 42 and the gate 43 to move upward together. During the upward movement of the gate 43, it no longer obstructs the water flow, and the flowing water carries the fish down the inclined box 454 to the lower sluice gate 3.

[0037] The control component 45 includes a circular tube 451 connected to one side of the bottom end of the upper gate head 2 and the lower gate head 3. One end of the circular tube 451 is connected to the inside of the gate chamber 1. Rotating rods 452 are rotatably connected to both ends of one side of the inner wall of the gate chamber 1. Square fan rollers 453 are rotatably connected to both ends of the rotating rods 452. The square fan rollers 453 are located inside the gate chamber 1.

[0038] The outer wall of the rotating rod 452 is rotatably connected to the inclined box 454. Both sides of the inclined box 454 are fixedly connected to the side wall of the gate chamber 1. The outer walls of the two ends of the rotating rod 452 away from the square fan roller 453 are fixedly connected to the stainless steel ball reciprocating screw 455. One end of the stainless steel ball reciprocating screw 455 is threadedly connected to the outer wall of the threaded plate 456. Limiting holes 457 are opened on both sides of the top of the inclined box 454.

[0039] Using the above scheme: water flows into gate chamber 1 through the circular pipe 451 at the upper gate head 2, and then flows through gate chamber 1 into the circular pipe 451 at the lower gate head 3, forming a water circulation. Inside gate chamber 1, the thrust of the water flow drives the square fan roller 453 to rotate, thereby driving the rotating rod 452 to rotate. The rotating rod 452 drives the stainless steel ball reciprocating screw 455 to rotate, which in turn drives the threaded plate 456 to reciprocate along the inner wall of the inclined box 454.

[0040] A slider 458 is fixedly connected to the top of the threaded plate 456. The outer wall of the slider 458 is slidably connected to the inner wall of the limiting hole 457. A strip shell 459 is fixedly connected to the top of the slider 458. A compression spring 4510 is fixedly connected to one side of the inner wall of the strip shell 459. A slider 4511 is fixedly connected to one end of the compression spring 4510. The outer wall of the slider 4511 is slidably connected to the inner wall of the strip shell 459.

[0041] A vertical rod 4512 is fixedly connected to the top of the slide bar 4511. A square roller 4513 is rotatably connected to the outer wall of one end of the vertical rod 4512. A square mesh 4514 is fixedly connected between the two square rollers 4513. A positioning rod 4515 is fixedly connected to the bottom of the square mesh 4514. Both ends of the positioning rod 4515 are fixedly connected to the side wall of the square roller 4513.

[0042] Using the above scheme: the two threaded plates 456 gradually approach each other, pushing the slider 458 to move inside the strip shell 459, which in turn drives the slider 4511 and the vertical rod 4512 to move closer to the square roller 4513. The square roller 4513 drives the square mesh 4514 to move closer to each other. Under the restriction of the positioning rod 4515 and the elastic force of the compression spring 4510, the slider 4511 slides on the inner wall of the strip shell 459. At the same time, the square mesh 4514 performs forward and reverse flipping motions along the inclined plane of the inclined box 454. During the flipping process, the square mesh 4514 can push the water flow.

[0043] like Figures 1 to 9As shown, the side wall of the connecting plate 42 is provided with an auxiliary component 46. The auxiliary component 46 includes a connecting rod 461 fixedly connected between the two connecting plates 42. A block 462 is fixedly connected to the outer wall of the middle end of the connecting rod 461, and a round rod 463 is fixedly connected to the bottom of the block 462.

[0044] A water storage shell 464 is fixedly connected to the bottom of the round rod 463. The top outer wall of the water storage shell 464 is slidably connected to the inner wall of the gate chamber 1. A sliding plate 465 is slidably connected to the bottom outer wall of the round rod 463. Elastic telescopic rods 466 are fixedly connected to both sides of the bottom of the sliding plate 465. A sealing plate 467 is fixedly connected to the bottom of the elastic telescopic rods 466.

[0045] The above scheme is adopted: when the water storage shell 464 moves upward, the water storage shell 464 drives the sliding plate 465, the elastic telescopic rod 466 and the sealing plate 467 to move. During the movement, the sealing plate 467 can contact the bottom of the gate chamber 1, thereby sealing the opening of the gate chamber 1 and preventing water from flowing out through the opening of the gate chamber 1.

[0046] The sealing plate 467 is set outside the water storage shell 464. The top two sides of the inner wall of the gate chamber 1 are fixedly connected to the fixing rod 468. The bottom of the fixing rod 468 is fixedly connected to the squeezing plate 469. One end of the round rod 463 passes through and is slidably connected to the inner wall of the squeezing plate 469.

[0047] Using the above scheme: when water flows through the gate chamber 1, the water will be stored inside the water storage shell 464. When the connecting plate 42 rises, the connecting plate 42 drives the connecting rod 461 and the block 462 to rise. The block 462 drives the round rod 463 and the water storage shell 464 to rise. During the rise of the water storage shell 464, it will come into contact with the stationary squeezing plate 469. The squeezing plate 469 slides inside the water storage shell 464 and squeezes the water inside the water storage shell 464.

[0048] The bottom of the extrusion plate 469 is provided with a flow propulsion assembly 47. The flow propulsion assembly 47 includes an elastic tube 471 connected to one side of the bottom of the extrusion plate 469. One end of the elastic tube 471 is connected to a drainage tank 472. One side of the drainage tank 472 is fixedly connected to one side of the top connecting plate 42. A drainage port 473 is provided at the bottom of the drainage tank 472.

[0049] Using the above scheme: After the water flows into the elastic pipe 471, it flows into the drainage tank 472 through the elastic pipe 471. The water flows downward through the drain outlet 473 in the drainage tank 472, effectively dispersing the fish gathered at the upper gate head 2. The discharged water flows down along the top of the inclined box 454, promoting the migration of the fish and improving the efficiency of the fish's downward movement.

[0050] Working principle and usage process of this invention:

[0051] The sonic fish attractor 44 is activated, which guides the fish in the river to the gate 43 at the upper sluice gate 2. When a group of fish gathers, the electric telescopic rod 41 is activated. The electric telescopic rod 41 drives the connecting plate 42 and the gate 43 to move upward. During the upward movement of the gate 43, the water flow is no longer blocked. The flowing water carries the fish down the inclined box 454 to the lower sluice gate 3, allowing the fish to pass through the dam and ensuring the health and stability of the aquatic ecosystem. During this process, water flows through the circular pipe 451 at the upper gate head 2 into the interior of the gate chamber 1. The water then flows through the gate chamber 1 into the circular pipe 451 at the lower gate head 3, causing the water to flow. As the water flows within the gate chamber 1, the thrust of the water causes the square fan roller 453 to rotate, which in turn drives the rotating rod 452. The rotating rod 452 then drives the stainless steel ball reciprocating screw 455 to rotate. The stainless steel ball reciprocating screw 455 drives the threaded plate 456 to reciprocate along the inner wall of the inclined box 454. The two threaded plates 456 move closer to each other, causing the threaded plate 456 to drive the slider 458 and the strip shell 45... 9. The movement of the strip shell 459 causes the slide bar 4511, vertical rod 4512, and square roller 4513 to move closer together. The square roller 4513 then causes the square net 4514 to move closer together. Under the resistance of the positioning rod 4515 and the elastic compression of the compression spring 4510, the slide bar 4511 slides on the inner wall of the strip shell 459. Simultaneously, the square net 4514 rotates forward and backward along the inclined plane of the inclined box 454. During this rotation, the square net 4514 pushes the water flow, effectively slowing its speed and reducing its impact on the fish, ensuring they can pass smoothly through the waterway. When the two threaded plates 456 move away from each other, the square net 4514 lies horizontally on top of the inclined box 454, blocking the water flow and indirectly creating several suitable resting areas for the fish to rest briefly and recover their energy.

[0052] When the water flow is rapid, the water flows simultaneously at the top of the inclined box 454 and inside the gate chamber 1. The rapid flow increases the rotation speed of the square fan roller 453, which in turn increases the rotation speed of the square net 4514 in the control component 45. The rotating net 4514 pushes the water flow in the opposite direction, slowing down the flow and preventing fish from drowning or being injured due to excessive water velocity. When the water flow is slow, the rotation speed of the square fan roller 453 decreases, and one end of the slowly rotating net 4514 rotates with the water flow, changing the direction and flow pattern of the water. This is crucial for avoiding turbulent flow or eddies and providing a stable water flow environment, allowing fish to migrate downstream along the stable water flow. By adapting to changes in water flow velocity and adjusting the rotation efficiency of the square fan roller 453 in real time, stable migration of fish is ensured.

[0053] When water flows through the gate chamber 1, it is stored inside the water storage shell 464. When the connecting plate 42 rises, it drives the connecting rod 461 and the block 462 to rise. The block 462 drives the round rod 463 and the water storage shell 464 to rise. During the rise of the water storage shell 464, it comes into contact with the stationary squeezing plate 469. The squeezing plate 469 slides inside the water storage shell 464, squeezing the water inside the water storage shell 464, causing the water to enter the elastic tube 471. The water enters the drainage box 472 through the elastic tube 471. The water is discharged downward through the drainage port 473 opened at the drainage box 472, draining the fish gathered at the upper gate head 2. At this time, the discharged water can be carried and moved downward along the top of the inclined box 454, promoting the efficiency of fish migration and preventing fish from stagnating at the upper gate head 2, which would affect the migration of other fish. As the water storage shell 464 moves upward, it drives the sliding plate 465, the elastic telescopic rod 466, and the sealing plate 467 to move. During the movement of the sealing plate 467, it can contact the bottom of the gate chamber 1, thereby sealing the opening of the gate chamber 1 and preventing water from flowing out through the opening of the gate chamber 1, which would affect the stability of the rotation of the square fan roller 453 driven by the water flow, and ensure the stability of the device operation.

6. A method for operating a fish passage facility using a dam based on ecological flow regulation, employing the fish passage facility using a dam based on ecological flow regulation as described in claim 5, characterized in that: S1. Start the sonic fish attractor (44). The sonic fish attractor (44) will guide the fish in the river to the gate (43) at the upper gate (2). When a group of fish gathers, start the electric telescopic rod (41). The electric telescopic rod (41) will drive the connecting plate (42) and the gate (43) to move upward. During the upward movement of the gate (43), the water flow will no longer be blocked. The flowing water will carry the fish down the inclined box (454) to the lower gate (3). S2. Water flows through the round pipe (451) at the upper gate (2) into the interior of the gate chamber (1). Water flows through the gate chamber (1) into the round pipe (451) at the lower gate (3). During the flow of water in the gate chamber (1), the thrust of the water causes the square fan roller (453) to drive the rotating rod (452) to rotate. The rotating rod (452) drives the stainless steel ball reciprocating screw (455) to rotate. The stainless steel ball reciprocating screw (455) drives the threaded plate (456) to move back and forth along the inner wall of the inclined box (454). The two threaded plates (456) move closer to each other. S3. The threaded plate (456) drives the slider (458) and the strip shell (459) to move. The strip shell (459) drives the slide bar (4511) and the vertical rod (4512) and the square roller (4513) to move closer to each other. The square roller (4513) drives the square net (4514) to move closer to each other. Under the resistance of the positioning rod (4515) and the elastic compression of the compression spring (4510), the slide bar (4511) slides on the inner wall of the strip shell (459). At the same time, the square net (4514) can rotate forward and backward along the inclined plane of the inclined box (454). During the rotation of the square net (4514), it can push the water flow.
