Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and more specifically, to an ecological rest station. Background Technology

[0002] In water conservancy projects, fishways are often constructed to help fish migrate through obstacles such as dams and weirs, providing them with passages upstream. However, the waters on the downstream slopes are vast, and the entrances to the fishways are relatively small. Even with multiple entrances, fish often find it difficult to find the fishway entrance in the wide expanse of water, greatly limiting the fishway's passage capacity. Summary of the Invention

[0003] This application provides an ecological rest station, which aims to attract fish into the fishway by setting up a movable biomimetic platform at the entrance of the fishway, thereby improving the efficiency of fish passage and having a long service life.

[0004] This application provides an ecological rest station, including: a biomimetic platform for fish to rest on; a lifting device installed on the biomimetic platform for driving the biomimetic platform to sink or float; and a traction device connected to the biomimetic platform for driving the biomimetic platform to move to enter or exit the aquatic environment.

[0005] Based on the above embodiments, the ecological station achieves adaptive adjustment under different water flow conditions through a biomimetic platform structure that can be raised, lowered, and moved, which not only protects the platform structure but also improves the migration efficiency of fish.

[0006] In some embodiments, the ecological station further includes a flow-generating structure installed on the biomimetic platform and used to agitate the water flow in the area where the biomimetic platform is located.

[0007] Based on the above embodiments, by actively adjusting the local water flow state, the fish gathering effect and ecological adaptability of the ecological station under different river channels and seasonal conditions are improved, the utilization efficiency of the fishway entrance is increased, and the water flow disturbance can also increase dissolved oxygen in the water, promote the growth of food organisms, and guide the fish to move towards the fishway entrance.

[0008] In some embodiments, the flow-generating structure includes a regulating gate movably connected to the biomimetic platform and used to change the velocity of the water flowing into the biomimetic platform.

[0009] Based on the above embodiments, the regulating gate provides a simple and intuitive water flow control method, enabling the ecological station to more accurately adapt to the local hydrological environment and the behavioral needs of the target fish species, and enhancing the facility's responsiveness and control flexibility in the face of complex water flow conditions.

[0010] In some embodiments, the flow-generating structure includes a flow-generating pump mounted on the biomimetic platform; and / or, the flow-generating structure includes a flow-pushing aerator mounted on the biomimetic platform.

[0011] Based on the above embodiments, the use of the flow-generating pump and the flow-pushing aerator, either individually or in combination, enables the ecological station to operate flexibly under different hydrological and water quality conditions: in low-oxygen or still water environments, the flow-pushing aerator can improve the living conditions of fish; when the water flow is insufficient, the flow-generating pump can supplement the flow rate to maintain the fish-attracting effect, thereby enhancing the adaptability and functionality of the ecological station in diverse aquatic environments. By actively regulating water flow and water quality parameters, the station improves the fish's willingness to inhabit the area and the ecological vitality of the fishway entrance area.

[0012] In some embodiments, the traction device further includes a limiting post for fixing in an aquatic environment and abutting against the periphery of the biomimetic platform.

[0013] Based on the above embodiments, the limiting structure improves the positional stability of the ecological station under the action of water flow, reduces the risk of decreased fish gathering effect or collision with surrounding structures due to the drift of the bionic platform, and provides a reliable spatial reference for the docking of the traction device.

[0014] In some embodiments, the lifting device includes a float that can be filled and defilled with water.

[0015] Based on the above embodiments, the design of multiple independent buoys improves the system's safety redundancy; even if a single buoy leaks, the remaining buoys can still maintain the platform's basic buoyancy. The rigid connection between the biomimetic platform and the buoys ensures the platform's structural stability during floating and sinking.

[0016] In some embodiments, the biomimetic platform includes a main frame, with the pontoon laid at the bottom and / or sides of the main frame.

[0017] Based on the above embodiments, the integrated design of the pontoon and the main frame ensures buoyancy supply while optimizing the stress distribution of the platform structure, enabling the ecological station to maintain a stable posture under the action of rising, sinking and water flow, thus extending the service life of the structure.

[0018] In some embodiments, the traction device includes a drive component, a connector, and a track. The connector connects the drive component and the bionic platform. The drive component drives the bionic platform to move along the track to enter or exit the water environment via the connector. Alternatively, the traction device includes a drive component and a connector. The connector connects the drive component and the bionic platform. The bottom of the bionic platform is also provided with rollers. The drive component drives the bionic platform to enter or exit the water environment via the connector.

[0019] Based on the above embodiments, the traction device provides reliable location scheduling capabilities for the ecological rest station. The track-based implementation enables precise path control and location replication, suitable for applications with fixed safety platforms or installation foundations. The trackless method using rollers improves site adaptability and allows for flexible deployment in waters without dedicated tracks. Both implementations enable the ecological rest station 1 to be quickly moved out of the water during floods or maintenance, avoiding structural damage, and to be accurately reset to its working position when needed, ensuring the reusability and ease of operation of the facility.

[0020] In some embodiments, the biomimetic platform includes a main frame and attachments disposed on the main frame; the attachments include at least one of branches, hollowed-out artificial reefs, and aquatic plants.

[0021] Based on the above embodiments, the combination of various accessories can meet the habitat needs of various fish species, forming an underwater habitat that is closer to nature, thereby increasing the concentration and dwell time of fish in the ecological station area and enhancing the ecological attractiveness of the fishway entrance.

[0022] In some embodiments, the biomimetic platform is also equipped with detection devices.

[0023] Based on the above embodiments, through systematic analysis of the data collected by the detection equipment, the fish-attracting effect of the ecological rest station can be more accurately evaluated, and a scientific basis can be provided for optimizing the platform structure, adjusting water flow conditions, and improving fish-attracting strategies. This structure realizes the functional expansion of the ecological rest station from a passive habitat to an intelligent monitoring node, forming a more complete integrated system of fish attraction and ecological monitoring, which helps to improve the scientific nature and pertinence of fish protection and migration channel construction.

[0024] Based on the ecological rest station proposed in this application, by setting up a lifting device and a traction device on the bionic platform, when the water flow velocity increases, the lifting device drives the bionic platform to float to the water surface. At the same time, the traction device is activated, and the bionic platform moves to the riverbank under the traction of the traction device, avoiding the high-speed water flow, thereby preventing the bionic platform from being washed away and damaged by the high-speed water flow.

[0025] In this way, the biomimetic platform structure, which can be raised, lowered, and moved, enables the ecological station to adapt to different water flow conditions, thus protecting the biomimetic platform and improving the migration efficiency of fish. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] In water conservancy projects, fishways are often constructed to help fish migrate through obstacles such as dams and weirs, providing them with passages upstream. However, the waters on the downstream slopes are vast, and the entrances to the fishways are relatively small. Even with multiple entrances, fish often find it difficult to find the fishway entrance in the wide expanse of water, greatly limiting the fishway's passage capacity.

[0031] Based on the current state of technology, such as Figure 1-5 As shown, this application embodiment provides an ecological rest station 1, including a biomimetic platform 11, a lifting device 12, and a traction device 13.

[0032] Specifically, the bionic platform 11 is movably positioned on one side near the fishway 3, providing a resting place for fish, allowing schools of fish to enter the fishway 3 via the bionic platform 11. A lifting device 12 is installed on the bionic platform 11 and is used to drive the bionic platform 11 to sink or rise. A traction device 13 is connected to the bionic platform 11; when the bionic platform 11 rises to a certain height (…),… Figure 3 (At the position indicated by the dotted line), it can be towed to the shore by the towing device 13. Figure 2 (at the position indicated by the dashed line), and completely separated from the aquatic environment.

[0033] The water environment here can refer to rivers, lakes, reservoirs, etc., without any restrictions. The following uses a river as an example to illustrate the scheme of this application.

[0034] Understandably, the biomimetic platform 11 is placed at the entrance of the fishway 3 to simulate the natural environment by planting aquatic plants and setting up shelter structures, thereby attracting fish to gather. However, the biomimetic platform, which is fixedly placed at the entrance of the fishway, cannot adapt to changes in water level and flow velocity. The vegetation is easily destroyed by the impact of high-speed water flow, which not only affects the ecological function but also increases maintenance costs.

[0035] Therefore, a mobile bionic platform 11 is needed to adapt to changes in water level and flow velocity. Specifically, when the water flow in the river channel 2 is slow and the water level is suitable, the lifting device 12 drives the bionic platform 11 to sink to the riverbed 22. The vegetation planted on the bionic platform 11 forms an ecological attraction zone, guiding fish to gather and enter the fishway 3. When the water flow velocity increases, the lifting device 12 drives the bionic platform 11 to float to the water surface 23. At the same time, the traction device 13 is activated, and the bionic platform 11 moves to the riverbank 21 under the traction of the traction device 13, avoiding the high-speed water flow and thus preventing the vegetation from being washed away and damaged by the high-speed water flow.

[0036] In this way, the biomimetic platform 11 structure, which is liftable and movable, enables the ecological station 1 to adapt to different water flow conditions, thus protecting vegetation and improving the migration efficiency of fish.

[0037] In one embodiment, such as Figure 3As shown, the ecological station 1 also includes a flow-generating structure 14. The flow-generating structure 14 is installed on the upstream side, surface, or interior of the bionic platform 11 to disturb the water flow in the area where the bionic platform 11 is located.

[0038] Specifically, the flow-generating structure 14 can be a low-speed propeller, an axial-flow impeller, an adjustable-angle guide vane, or a flow rate regulating valve with adjustable opening, etc. The number of flow-generating structures 14 can be one, or multiple structures can be arranged circumferentially or longitudinally on the platform. The driving method of the flow-generating structure 14 can be electric drive, hydraulic drive, or mechanical transmission, and its output can be automatically adjusted according to the water flow sensor signal, or it can be remotely set by the control unit.

[0039] Understandably, when the flow-generating structure 14 is working, it generates directional or diffuse disturbances to the water flow around the bionic platform 11, thereby changing the local flow velocity and flow pattern, creating suitable flow velocity conditions for fish migration or aggregation around the bionic platform 11, so as to attract specific fish species.

[0040] In this way, by actively adjusting the local water flow, the fish-gathering effect and ecological adaptability of Ecological Station 1 under different river conditions and seasons are improved, the utilization efficiency of the fishway 3 entrance is increased, and the water flow disturbance can also increase dissolved oxygen in the water, promote the growth of food organisms, and guide the fish to move towards the fishway 3 entrance.

[0041] In one embodiment, such as Figure 2 and Figure 4 As shown, the flow-generating structure 14 includes a regulating gate 141. The regulating gate 141 is movably connected to the biomimetic platform 11 and is used to change the velocity of the water flowing into the biomimetic platform 11.

[0042] It should be noted that the regulating door 141 can be a flat door, a louvered door, an arc-shaped deflector, or a gate-type structure. The regulating door 141 can be connected to the edge, top, or upstream side of the bionic platform via hinges, slide rails, or pivots, allowing it to rotate around an axis, translate along a slide rail, or swing within a certain angle range. The opening degree, angle, or position of the regulating door 141 can be manually adjusted or automatically controlled by a motor, hydraulic cylinder, or pneumatic actuator. There can be one regulating door 141 or multiple regulating doors arranged along the width of the platform. The regulating door 141 can be made of corrosion-resistant metal, engineering plastics, or composite materials.

[0043] In other words, by changing its opening or angle, the regulating gate 141 can physically regulate the cross-sectional area and direction of the water flowing through the biomimetic platform 11. When the regulating gate 141 is partially closed, it can throttle the upstream flow, reduce the flow velocity in the platform area, and create habitat conditions for fish that prefer slow-flowing environments. When the regulating gate 141 is adjusted to a specific guiding angle, it can guide or accelerate the water flow, forming a directional flow field that attracts migratory fish.

[0044] In this way, the regulating gate 141 provides a simple and intuitive water flow control method, enabling the ecological station 1 to more accurately adapt to the local hydrological environment and the behavioral needs of the target fish species, and enhancing the facility's responsiveness and control flexibility in the face of complex water flow conditions.

[0045] In one embodiment, such as Figure 5 As shown, the flow-generating structure 14 includes a flow-generating pump 142 mounted on the biomimetic platform 11. Specifically, the flow-generating pump 142 is a power device for generating directional water flow, and can be a submersible centrifugal pump, axial flow pump, or mixed flow pump. The flow-generating pump 142 is fixedly mounted on the upstream side, side, or bottom support of the biomimetic platform 11. The inlet of the flow-generating pump 142 faces outward or downward towards the biomimetic platform, while the outlet faces upward and / or in a specific direction around the biomimetic platform 11.

[0046] Specifically, when the flow-generating pump 142 is running, it draws in water from the inlet and sprays it out from the outlet, thereby actively disturbing the water flow above and / or around the biomimetic platform 11, forming a local circulation or directional flow of water. The number of flow-generating pumps can be one, or multiple pumps evenly arranged along the circumference of the platform. The flow rate and spray direction of the flow-generating pump 142 can be controlled by adjusting the motor speed or by adding a flow guide.

[0047] Furthermore, the flow-generating structure 14 also includes a propulsion aerator installed on the biomimetic platform 11. The propulsion aerator is a power unit that combines propulsion and aeration functions, typically comprising a motor, impeller, and air injection unit. The propulsion aerator is installed on the surface of the biomimetic platform 11 or in the water above the biomimetic platform 11 via a bracket or suspension mechanism. When the impeller of the propulsion aerator rotates, it propels the water flow; the direction of propulsion is adjustable to disturb the water flow above the biomimetic platform 11. Simultaneously, the air injection unit releases air or oxygen into the water in front of or around the impeller through pipes or diffusers, thereby increasing the oxygen content in the water flow in the area where the biomimetic platform 11 is located.

[0048] In other words, the flow-generating pump 142 can actively create controllable water flow conditions around the biomimetic platform 11, simulating the flow patterns preferred by fish by disturbing the water flow above and around it, thus guiding fish to gather. The flow-pushing aerator, while disturbing the water flow above, continuously replenishes oxygen to the water body, increasing the dissolved oxygen level in the local water area.

[0049] In this way, by using the flow-generating pump 142 and the flow-pushing aerator individually or in combination, the ecological station 1 can operate flexibly under different hydrological and water quality conditions: in low-oxygen or still water environments, the flow-pushing aerator can improve the living conditions of fish; when the water flow is insufficient, the flow-generating pump 142 can supplement the flow rate to maintain the fish-attracting effect, thereby enhancing the adaptability and functionality of the ecological station 1 in diverse aquatic environments. By actively regulating water flow and water quality parameters, it improves the fish's willingness to inhabit the area and the ecological vitality of the fishway entrance area.

[0050] In one embodiment, such as Figure 6 As shown, the ecological station 1 also includes a limiting column 15. The limiting column 15 is a vertical or inclined columnar structure used to fix itself in the aquatic environment, which can abut against and limit the periphery of the biomimetic platform 11.

[0051] Specifically, the limiting post 15 can be made of steel, concrete piles, composite materials, or anti-corrosion wooden piles. The bottom end of the limiting post 15 is fixed to the riverbed, lakebed, or artificial foundation through pile foundations, anchor blocks, or gravity bases, while the top end can be above the water surface or underwater. The number of limiting posts 15 can be two, four, or more, arranged at intervals along the circumference of the biomimetic platform 11.

[0052] It should be noted that the limiting posts 15 can be set on both sides of the bionic platform 11 along the direction of water flow, or on the side of the bionic platform 11 closer to the downstream side, or on the side of the bionic platform 11 away from the riverbank 21. There are no restrictions on the specific number and installation position, as long as the limiting function of the limiting posts 15 can be met.

[0053] Understandably, the limiting post 15 provides physical constraints and positioning references for the bionic platform 11. When the bionic platform 11 is in the sinking working state, the limiting post 15 can restrict the horizontal displacement and rotation of the platform, preventing it from deviating from the preset position under the impact of water flow. During the floating process of the bionic platform 11, the limiting post 15 can play a vertical guiding role, ensuring that the bionic platform 11 rises smoothly along the predetermined path.

[0054] In this way, the limiting structure improves the positional stability of the ecological station 1 under the action of water flow, reduces the risk of decreased fish gathering effect or collision with surrounding structures due to the drift of the bionic platform 11, and provides a reliable spatial reference for the docking of the traction device 13.

[0055] In one embodiment, such as Figure 3 and Figure 5As shown, the lifting device 12 includes inflatable and deflated pontoons 121. Each pontoon 121 is a sealed chamber structure used to provide buoyancy. There can be two or more pontoons 121, symmetrically arranged along the length or width of the bionic platform 11. Each pontoon 121 in the ecological station 1 is an independent sealed structure. The pontoon 121 is equipped with inflatable and deflated pipes to control the water volume inside, enabling the equipment to float and sink. The pontoons 121 are fixedly connected to the bionic platform 11, and the bionic platform 11 and pontoons 121 are fixed together by detachable connections such as bolts or clamps. During the inflation and deflation process, the pontoons 121 and the bionic platform 11, as a whole, synchronously complete the floating and descending actions.

[0056] In other words, the floats 121 independently control the filling and draining of water to regulate the buoyancy of the bionic platform 11. When water is added to the floats 121, the buoyancy decreases, and the bionic platform 11 sinks to its working position; when water is drained from the floats 121 and air is added, the buoyancy increases, and the bionic platform 11 rises to the surface. The connection between the bionic platform 11 and the multiple floats 121 provides the bionic platform 11 with uniform force distribution, ensuring the structural stability of the bionic platform 11 during the buoyancy process. Simultaneously, the design of multiple independent floats 121 improves the system's safety redundancy; even if a single float 121 leaks, the remaining floats 121 can still maintain the platform's basic buoyancy.

[0057] In one embodiment, such as Figure 3 and Figure 5 As shown, the biomimetic platform 11 includes a main frame 111. Floating boxes 121 are laid on the bottom and / or sides of the main frame 111. Specifically, when the floating boxes 121 are laid on the bottom of the main frame 111, multiple floating boxes 121 are evenly fixed to the lower surface of the main frame 111; when the floating boxes 121 are laid on the sides of the main frame 111, the floating boxes 121 are arranged longitudinally or laterally along the sides of the main frame 111 and are fixedly connected to the structure of the main frame 111. The arrangement of the floating boxes 121 can be designed according to the structure of the main frame and buoyancy requirements, for example, multiple floating boxes 121 can be evenly arranged on the bottom of the main frame 111, or side floating boxes 121 can be symmetrically arranged around the main frame 111.

[0058] Understandably, the main frame 111 provides a reliable installation foundation and spatial layout for the pontoons 121, allowing the buoyancy distribution to match the structure of the biomimetic platform 11. Laying the pontoons 121 at the bottom of the main frame 111 can lower the overall center of gravity of the platform and improve stability during lifting and lowering; the side pontoons 121 can provide lateral buoyancy support to the main frame 111, enhancing the platform's anti-tilting ability.

[0059] In addition, the main frame 111 can be made of steel or composite material, or it can be a pipe structure. When the bionic platform 11 needs to sink, the inside of the pipe can be filled with water, which will sink the bionic platform 11 together with the float 121.

[0060] In this way, the integrated design of the pontoon 121 and the main frame 111 ensures buoyancy supply while optimizing the stress distribution of the platform structure, enabling the ecological station 1 to maintain a stable posture under the action of floating, sinking and water flow, and extending the service life of the structure.

[0061] In one embodiment, such as Figure 7 As shown, the traction device 13 includes a drive component 131, a connector 132, and a track 133. Specifically, the drive component 131 is a power-providing device, which can be an electric winch, a hydraulic winch, or a traction motor. The connector 132 is a component that connects the drive component 131 and the bionic platform 11, and can be a wire rope, chain, traction rod, or cable. The track 133 is used to guide and support the movement of the bionic platform 11, and can be a steel rail, concrete chute, guide trough, or chain track system laid on the riverbank 21.

[0062] Understandably, one end of the connector 132 is connected to the drive unit 131, and the other end is connected to the bionic platform 11. When the drive unit 131 is running, it provides traction through the connector 132, driving the bionic platform 11 to move along the track 133, thereby pulling the bionic platform 11 from the water to a safe position on the riverbank 21, or moving it from the riverbank 21 to a working position in the water.

[0063] In another embodiment, such as Figure 5 As shown, the traction device 13 may further include a drive component 131 and a connector 132, with the connector 132 connecting the drive component 131 and the bionic platform 11. A roller 134 is also provided at the bottom of the bionic platform 11. The roller 134 is mounted on the bottom of the bionic platform 11, and the drive component 131 provides traction force through the connector 132, driving the bionic platform 11 with the roller 134 to move without tracks, thus enabling entry into or exit from the aquatic environment.

[0064] In this way, the traction device 13 provides the bionic platform 11 with reliable position scheduling capabilities. The implementation with the track 133 enables precise path control and position reproduction, suitable for application scenarios with fixed safety platforms or installation foundations. The trackless method using rollers 134 improves site adaptability and can be flexibly deployed in waters without dedicated tracks. Both implementations enable the ecological station 1 to be quickly moved out of the water during floods, maintenance, etc., avoiding structural damage, and can be accurately reset to the working position when needed, ensuring the reusability and ease of operation of the facility.

[0065] In one embodiment, such as Figure 6 and Figure 8 As shown, the traction device 13 also includes a drive component 131, a connector 132, a track 133, and a roller 134. The drive component 131 provides traction force through the connector 132, driving the roller 134 to enter the track 133 and slide along the track 133, thereby driving the bionic platform 11 to move along the track 133 to enter or exit the water environment.

[0066] Specifically, one end of the track 133 located within the river channel 3 is provided with a funnel-shaped guide opening 1331. The guide opening 1331 is used to guide the roller 134 to enter and slide onto the track 133. That is, the width of the guide opening 1331 facing the roller 134 is larger and gradually decreases along the extension direction of the track 133. At this time, the cross-sectional shape of the guide opening 1331 can be V-shaped, U-shaped, or trapezoidal, with a V-shaped structure being preferred.

[0067] Specifically, when the bionic platform 11 rises to the water surface 23, the traction device 13 pulls the bionic platform 11, causing the bionic platform 11 to gradually approach the shore. The roller 134 gradually approaches the track 133 along with the bionic platform 11. During the process of the roller 134 cooperating with the track 133, the roller 134 first enters the guide port 1331. During the process of the bionic platform 11 being pulled, the roller 134 moves along the direction where the width of the guide port 1331 gradually decreases until it enters the track 133 and moves along the track 133.

[0068] Furthermore, the maximum opening of the guide port 1331 can extend to the riverbed 22, so that even if the water level is different, at least part of the guide port 1331 can be exposed above the water surface 23, thereby ensuring the normal guiding function of the guide port 1331.

[0069] In this way, by setting a guide opening 1331 with a gradually decreasing width, a larger fault tolerance space is provided when the roller 134 and the track 133 initially make contact, making it easier for the roller 134 to enter the track 133. This effectively solves the problem of docking difficulties caused by water flow fluctuations or platform drift, and improves the reliability of equipment operation.

[0070] In one embodiment, such as Figure 2 As shown, multiple tracks 133 are spaced apart along the length of the bionic platform 11, and multiple rollers 134 correspond one-to-one with multiple tracks 133.

[0071] Understandably, the multiple tracks 133 can be arranged at equal intervals or at non-equal intervals depending on the force requirements, with a preferred symmetrical arrangement at equal intervals. The number of rollers 134 is the same as that of the tracks 133, and their positions are correspondingly set. Driven by the traction device 13, the rollers 134 can cooperate with their corresponding tracks 133 and slide along the tracks 133.

[0072] In this way, by arranging multiple tracks 133 at intervals along the length of the bionic platform 11 and forming a one-to-one correspondence with multiple rollers 134, the bionic platform 11 obtains evenly distributed support points during movement. This arrangement effectively disperses the platform's own weight and water flow impact loads, avoids deformation problems caused by excessive stress at a single point, and significantly improves structural stability.

[0073] In one embodiment, such as Figure 1-3 As shown, at least two traction devices 13 are spaced apart along the length of the bionic platform 11. Understandably, the traction devices 13 can be arranged symmetrically or asymmetrically according to the force requirements. A symmetrical arrangement is preferred. When the traction devices 13 are activated, they can be arranged on opposite sides of the bionic platform 11 along its length, forming a symmetrical traction force system on the bionic platform 11, thus ensuring that the bionic platform 11 is subjected to balanced forces.

[0074] This ensures that the bionic platform 11 receives a balanced traction force during movement, effectively avoiding platform deflection and jamming that may be caused by unilateral traction, and ensuring that the bionic platform 11 moves smoothly along the track 133.

[0075] In one embodiment, such as Figure 3-5 As shown, the biomimetic platform 11 includes a main frame 111 and an attachment 112 mounted on the main frame. The attachment 112 is an artificial component installed on the main frame 111 to provide a habitat structure and ecological functions. The attachment 112 includes at least one of the following: branches, perforated artificial reefs, and aquatic plants.

[0076] Specifically, the branches can be made of plastic, rubber, or natural wood, mimicking tree roots or branches, and are distributed in a forked or clustered manner. For example... Figure 10 and Figure 11 As shown, the hollowed-out artificial reef is a concrete block, ceramic component, or resin component with a porous or cavity structure, containing holes and channels of varying sizes. The aquatic plants can be imitation aquatic plants made of plastic fabric, silicone strips, or real aquatic plants suitable for underwater growth.

[0077] In other words, the main frame 111 provides a stable installation foundation and spatial layout for the attachments 112, while the attachments 112 together create a multi-layered, porous biomimetic habitat. The branch structure simulates an underwater root system, providing hiding places for small fish, while the holes and cavities of the artificial reef are suitable for fish of different sizes to inhabit and hide in. Biomimetic or real aquatic plants can further increase the attachment surface and promote the growth of microorganisms and algae.

[0078] In this way, the combination of various attachments 112 can meet the habitat needs of a variety of fish species, forming an underwater habitat that is closer to nature, thereby increasing the concentration and dwell time of fish in the ecological station area and enhancing the ecological attractiveness of the fishway entrance.

[0079] In one embodiment, the biomimetic platform 11 is also equipped with detection devices. These devices include at least one of an underwater camera and a sonar monitoring device. The underwater camera, used to acquire underwater images, is typically installed on the side, top, or inside an opening of the biomimetic platform to observe and record images of fish entering the ecological station in real time. The sonar monitoring device detects underwater objects using sound waves and is typically installed inside or at the bottom of the platform structure. It monitors the number, size, and movement patterns of fish by emitting and receiving sound wave signals.

[0080] In other words, the underwater cameras and sonar monitoring equipment installed in Eco-Station 1 can continuously monitor fish entering Eco-Station 1, collecting multiple data points including fish species, numbers, stay time, and activity patterns. This data can be transmitted to a data processing system via wired or wireless means for further analysis of fish migration habits, behavioral preferences, and response patterns to the Eco-Station environment.

[0081] In this way, through systematic analysis of the collected data, the fish-attracting effect of the ecological stations can be more accurately assessed, and a scientific basis can be provided for optimizing the platform structure, adjusting water flow conditions, and improving fish-attracting strategies. This structure realizes the functional expansion of the ecological stations from passive habitats to intelligent monitoring nodes, forming a more complete integrated system of fish attraction and ecological monitoring, which helps to improve the scientific nature and pertinence of fish protection and migration channel construction.
