Description

A fish habitat restoration device and restoration method Technical Field

[0001] This invention relates to the field of habitat restoration technology, and in particular to a fish habitat restoration device and method. Background Technology

[0002] With the rapid development of industrial and agricultural production, the continuous expansion of urban areas, and the large-scale discharge of land-based pollutants (including industrial wastewater, domestic sewage, agricultural runoff containing chemical fertilizers, and livestock manure), the global fishery ecosystem has been severely damaged. These pollutants have led to increasingly prominent eutrophication problems, causing a significant drop in dissolved oxygen levels and resulting in mass deaths of fish and other aquatic organisms. This not only destroys fish habitats, breeding grounds, and foraging grounds but also significantly reduces the stability and health of the entire aquatic ecosystem. Fish habitat restoration has become an urgent environmental problem to be addressed.

[0003] To improve the current situation, existing technologies commonly employ an ecological restoration method of "planting aquatic purifying plants on floating boards." This method utilizes plant roots to absorb pollutants such as nitrogen and phosphorus from the water, achieving water purification and aquatic vegetation reconstruction. However, existing floating board devices for fish habitat restoration still have several key shortcomings in practical applications, making them unsuitable for the restoration needs of complex aquatic environments. Specifically: Insufficient impact resistance and buffering capacity: Existing floating boards are mostly integral structures or simple splicing designs, lacking specialized force dispersion and buffering mechanisms. When encountering turbulent waters with large waves, the impact force of the water flow and waves acts directly on the floating board as a whole, unable to be effectively dispersed and transmitted through the structure. This leads to the floating board being prone to displacement and collisions, and the connection points becoming loose, deformed, or even broken due to concentrated stress, severely affecting the stability of the device.

[0004] Lack of height adjustment and fixing functions: The planting plate height of existing floating boards is mostly fixed, and the wind-receiving area and water flow resistance of the part above the water surface cannot be adjusted. In strong wind or turbulent water environment, excessive resistance can easily cause the floating board to be overturned. At the same time, there is no reliable linkage fixing structure between the floating board and the planting plate. Even after adjusting the position in a simple way, relative sliding can still easily occur, which further reduces the overall stability of the device.

[0005] Weak attitude leveling capability: Existing repair devices generally lack active attitude calibration and center of gravity adjustment structures. When one side of the floating plate is subjected to strong water flow impact or wind and waves and tilts, it cannot adjust its center of gravity through its own structure to restore a horizontal attitude. Long-term tilting can easily lead to root damage and poor growth of planted plants, or even cause the entire device to overturn and interrupt the repair process.

[0006] Poor maintenance convenience: When an integral or simply spliced ​​float plate is damaged in a part, the entire device needs to be dismantled and replaced. This is not only cumbersome and costly to operate, but it can also lead to interruptions in repair work and affect the continuity of water purification.

[0007] Limited power supply: Some repair devices with electric control functions rely on external power supply or battery power. External power supply is difficult to deploy due to the limitations of the aquatic environment, while batteries have problems such as short battery life and need to be replaced frequently, which seriously restricts the application of the device in remote waters or long-term repair scenarios.

[0008] The shortcomings of the existing technologies mentioned above prevent floating planter-based remediation devices from operating stably in complex aquatic environments. Aquatic plants are easily damaged, and their purification function cannot be sustained, ultimately affecting the effectiveness and efficiency of fish habitat restoration. Therefore, developing a fish habitat restoration device with strong impact resistance, flexible height and posture adjustment, reliable fixation, convenient maintenance, and self-powered operation is key to overcoming the current technological bottlenecks. Summary of the Invention

[0015] Preferably, the limiting structure includes a movable rod, a protrusion, a limiting block, a compression spring, and a limiting rod. A movable rod is fixedly connected to the bottom of two adjacent planting plates. A protrusion is fixedly connected to the bottom of each movable rod. Two limiting blocks are provided at the bottom of each protrusion. The two limiting blocks are fixedly connected to each other by a compression spring. A limiting rod is fixedly connected to the side of each limiting block away from the compression spring. An insertion hole is provided in the inner wall of the limiting groove, and the limiting rod is inserted into the insertion hole. The movable rod and the protrusion are located on top of the limiting block and are correspondingly arranged with respect to the limiting block. The side of the limiting block near the compression spring is inclined, and the bottom of the limiting block is slidably connected to the inner wall of the limiting groove.

[0019] In addition, the present invention also discloses a restoration method for the above-mentioned fish habitat restoration device, including the following steps: Step 1, device placement and initial fixation: The fish habitat restoration device is placed in the water body of the fish habitat to be restored. The device is floated and positioned by floats. The initial distribution of multiple floats is fixed by the cooperation of connecting columns and connecting blocks; Step 2, environmental monitoring and height adjustment start-up: Pressure changes caused by water flow or waves are sensed by pressure sensors on the floats. When the pressure reaches a preset threshold, the first electric push rod is activated, driving the moving plate to move the planting plate downwards, and simultaneously driving the telescopic cylinder to retract, reducing the height of the planting plate and reducing the area of ​​the device above the water surface exposed to wind and water flow resistance; Step 3, limiting and fixing the floats and planting plates: During the downward movement of the planting plate, the bottom moving rod and protrusion move downwards simultaneously. The protrusion presses the two limiting blocks along the inclined surface of the limiting block, causing the compression spring to stretch. The two limiting blocks drive the limiting rod away from each other until the limiting rod is inserted into the insertion hole in the inner wall of the limiting groove, completing the fixation of the floats and planting plates; Step 4, impact buffering and dispersion: When the water flow impacts the outside of the floats, adjacent floats move towards the connecting block. The device moves in one direction, and the mounting groove slides along the upper and lower sides of the connecting block, driving the first rack to move. The first rack meshes with the drive gear and rotating rod to rotate, and the gear drives the second rack to drive another float to move in the opposite direction. At the same time, the buffer springs on both sides of the connecting block are compressed, which, together with the float, drives the moving plate to slide along the bottom of the planting plate, and the telescopic cylinder drives the moving ring to move in the annular groove, thus dispersing and buffering the impact force. Step 5, posture leveling and center of gravity fixing: When the device tilts, the second electric push rod is activated to push the weight block to move along the groove to the opposite side of the tilt direction of the float, adjusting the device. Center of gravity; after moving to the preset position, start the motor to drive the threaded rod to rotate, causing the movable plate to slide along the inner wall of the weight block. The movable plate pushes the push plate to deflect, which in turn pushes the fixed plate to move towards the inner wall of the groove, so that the magnetic block on one side of the fixed plate is magnetically attracted to the magnetic block on the inner wall of the groove, thus completing the fixation of the weight block and realizing the horizontal attitude calibration of the device; Step 6, Continuous repair and maintenance: the aquatic purification plants in the planting port absorb water pollutants and improve the eutrophication state of the water body; regularly check the integrity of the float and replace the damaged floats individually to maintain the continuous repair function of the device.

[0020] The beneficial effects of this invention are as follows: 1. Enhanced impact buffering and dispersion, improving structural stability: This invention uses a gear moving structure (linked first rack, gear, and second rack) within the connecting block in conjunction with a buffer spring to bidirectionally transmit and disperse the impact force of water flow / waves to multiple floats, avoiding loosening, deformation, or breakage of the connecting parts due to concentrated force, effectively reducing the risk of float displacement and collision, and ensuring stable operation of the device in turbulent waters and areas with large waves.

[0021] 2. Achieving height adjustment and synchronous fixation, enhancing anti-interference capability: This invention uses a first electric push rod to drive the planting plate downward, which can flexibly reduce the area of ​​the device above the water surface that is subject to wind / water flow resistance, reducing the probability of being overturned; at the same time, through the linkage of the moving rod, the protrusion and the limiting structure, the floating block and the planting plate are fixed synchronously after the height is adjusted, avoiding relative sliding between the two, and further improving the overall stability of the device.

[0022] 3. Active posture leveling to prevent tipping and protect plant growth: This invention uses a second electric push rod to drive the weight block to adjust the center of gravity. With the fixed structure of the motor and magnetic block, it can actively calibrate the tilt posture of the device to prevent tipping caused by unilateral force. At the same time, it avoids damage to the plant roots caused by the tilt of the planting board, ensuring the stable growth of aquatic purification plants.

[0023] 4. Modular design reduces maintenance costs and ensures continuous repair: The floats of this invention adopt a circular array splicing structure. When a part of the float is damaged, it can be replaced individually without dismantling the entire device. This not only simplifies maintenance operations and reduces maintenance costs, but also avoids interruption of the repair process and maintains the continuous performance of the water purification function.

[0024] 5. Self-contained photovoltaic power supply, expanding applicable scenarios: The photovoltaic panel on the top of the planting board of this invention can convert solar energy into electrical energy to power components such as electric push rods and motors, eliminating the limitations of external power sources or batteries. It is suitable for scenarios such as remote water areas and long-term restoration, improving the environmental adaptability of the device.

[0025] 6. Improve the efficiency and effectiveness of habitat restoration: Through the stable operation of the device, this invention ensures that aquatic purifying plants continuously absorb pollutants such as nitrogen and phosphorus from the water, effectively improving the eutrophication state of the water body, while providing fish with a stable habitat and foraging space, thus helping to rapidly restore fish habitats and the ecosystem.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] Example 1: This invention provides a fish habitat restoration device, as shown in Figures 1 to 7, including a float 1, a planting plate 2 on the top of the float 1 for planting plants, a pressure sensor on the float 1, an installation rod fixedly connected to the top of the planting plate 2, a photovoltaic panel 7 fixedly connected to the top of the installation rod, a planting opening 6 at the top edge of the planting plate 2 located outside the photovoltaic panel 7, a groove inside the float 1, a telescopic cylinder 8 fixedly connected to the groove, a moving ring 25 fixedly connected to the top of the telescopic cylinder 8, an annular groove on the inner wall of the planting opening 6, the moving ring 25 located in the annular groove, the diameter of the annular groove being larger than the diameter of the moving ring 25, and a buffer limiting component on the float 1 and the planting plate 2; the buffer limiting component includes a connecting block 3, a connecting column 26, a gear moving structure, a first electric push rod 4, a moving plate 5, and a limiting structure. There are multiple floats 1, which are arranged in a circular array around the center of the planting plate 2. A connecting post 26 is set in the middle of the multiple floats 1. The top of the connecting post 26 is fixedly connected to the bottom of the planting plate 2. An installation groove is opened on one side of two adjacent floats 1. The inner walls of the upper and lower sides of the installation groove are slidably connected to the connecting block 3. One end of the connecting block 3 passes through the installation groove and is fixedly connected to the outside of the connecting post 26. A gear moving structure is set in the connecting block 3 to disperse the impact force on the floats 1 and the planting plate 2. A moving plate 5 is slidably connected to the bottom of the planting plate 2. The moving plate 5 is located between the planting plate 2 and the floats 1. An arc-shaped groove is opened on the inner wall of the float 1. A first electric push rod 4 is fixedly connected in the arc-shaped groove. The top of the first electric push rod 4 is fixedly connected to the moving plate 5. A limiting structure is set at the top of the float 1 and the bottom of the planting plate 2 to fix the multiple planting plates 2 and the floats 1.

[0029] Multiple floats 1 are assembled into a circular structure, which can adapt to different water flow conditions. Furthermore, the circular structure distributes forces relatively evenly in all directions when subjected to water flow and wave impacts, effectively dispersing external forces and further improving structural stability. Photovoltaic panels 7 can be installed on the floats 1 via planting plates 2 and mounting rods. The photovoltaic panels 7 convert solar energy into electrical energy to power the equipment and meet other power needs. Plants can be planted through planting openings 6 and telescopic cylinders 8, facilitating the restoration of the aquatic environment. Pressure sensors detect pressure changes on the floats 1. When the floats 1 are in a turbulent water area, the first electric push rod 4 is activated, causing the moving plate 5 and planting plate 2 to move downwards, and also moving the telescopic cylinder 8. The shrinkage mechanism lowers the height of the planting board 2, reducing the stress area and obstructing water flow, preventing the float 1 from tilting. Simultaneously, the gear mechanism allows adjacent floats 1 to move relative to each other, causing the moving plate 5 to move along the bottom of the planting board 2, which in turn moves the telescopic cylinder 8 and the moving ring 25. This movement of the moving ring 25 within its annular groove buffers the force on the float 1, reducing damage to plant roots caused by the float 1's swaying and displacement, creating more suitable growth conditions for the plants. Furthermore, the spliced ​​floats 1 allow for the replacement of damaged floats, further improving their stability and enhancing the plant's absorption and purification efficiency of pollutants.

[0030] As shown in Figures 4 and 6, two sets of gear moving structures are arranged symmetrically around the center of the connecting block 3. The gear moving structure includes a first rack 9, a second rack 10, a gear 11, a rotating rod, and a buffer spring 12. The first rack 9 is slidably connected inside the connecting block 3 and meshes with the gear 11. The rotating rod is fixedly connected to the middle of the gear 11, and the second rack 10 meshes with one side of the gear 11. Buffer springs 12 are fixedly connected to both sides of the connecting block 3. The side of the first rack 9 and the second rack 10 that is away from each other is fixedly connected to the inner wall of the mounting groove. The bottom of the second rack 10 is slidably connected to the inner wall of the mounting groove. Both ends of the rotating rod are rotatably connected to the inner wall of the mounting groove. The end of the buffer spring 12 that is away from the connecting block 3 is fixedly connected to the inner wall of the mounting groove. A limiting groove is opened at the top edge of two adjacent floats 1, and the limiting structure is located in the limiting groove.

[0031] The two sets of gear moving structures can improve the buffering effect when two adjacent floats 1 are subjected to impact force. When float 1 moves, it causes one of the adjacent floats 1 to move towards the connecting block 3. Since the connecting block 3 is located in the mounting groove and its upper and lower sides are slidably connected to the mounting groove, the mounting groove moves along the upper and lower sides of the connecting block 3, thereby driving the first rack 9 to move. This causes the gear 11 to drive the rotating rod to rotate along the inner wall of the mounting groove, causing the second rack 10 to drive the other float 1 to move in the opposite direction to the first rack 9, and causing the buffer spring 12 to be compressed. Through the relative movement of the first rack 9 and the second rack 10, and the compression of the buffer spring 12, the force on the adjacent floats 1 can be dispersed. The limiting groove facilitates the installation of the limiting structure. When the planting board 2 is lowered, the limiting structure can limit the two adjacent floats 1, thereby improving the stability of the connection between the two adjacent floats 1, which is conducive to improving the service life of the floats 1 and making it easier to use.

[0032] As shown in Figures 3 to 5, the limiting structure includes a moving rod 13, a protrusion 14, a limiting block 15, a compression spring 16, and a limiting rod 17. The bottom of two adjacent planting plates 2 are fixedly connected to the moving rod 13, and the bottom of the moving rod 13 is fixedly connected to the protrusion 14. Two limiting blocks 15 are provided at the bottom of the protrusion 14. The two limiting blocks 15 are fixedly connected to each other by the compression spring 16. The limiting rod 17 is fixedly connected to the side of the two limiting blocks 15 away from the compression spring 16. An insertion hole is opened in the inner wall of the limiting groove, and the limiting rod 17 is inserted into the insertion hole. The moving rod 13 and the protrusion 14 are located on the top of the limiting block 15 and are correspondingly arranged with the limiting block 15. The side of the limiting block 15 near the compression spring 16 is inclined, and the bottom of the limiting block 15 is slidably connected to the inner wall of the limiting groove.

[0033] When the planting plate 2 moves downward, it drives the moving rod 13 and the protrusion 14 to move downward, so that the protrusion 14 moves downward along the inclined surface of the limiting block 15 and squeezes the limiting block 15, causing the compression spring 16 to stretch. The two limiting blocks 15 drive the limiting rod 17 to move away from each other, so that the limiting rod 17 is inserted into the socket, thereby limiting the adjacent float 1, improving the stability of the planting plate 2 after it moves, making it less likely to be tilted, displaced or even overturned by the wind, and better able to stay in the original position, so as to ensure that the stability of the float 1 and the planting plate 2 is not affected.

[0034] As shown in Figures 3 and 7, a leveling structure is provided inside the groove. The leveling structure includes a second electric push rod 18, a weight 19, and a fixing structure. The second electric push rod 18 is fixedly connected to the inner wall of the groove. The weight 19 is fixedly connected to the second electric push rod 18, and both sides of the weight 19 are in contact with the inner wall of the groove. A fixing structure is provided in the middle of the weight 19. The fixing structure includes a motor 20, a threaded rod, a movable plate 21, a push plate 22, a fixed plate 23, and a magnet 24. The output end of the motor 20 is fixedly connected to the threaded rod, and the bottom of the threaded rod is rotatably connected to the inner wall of the weight 19. The threaded rod has threads. A movable plate 21 is connected, and push plates 22 are hinged to both ends of the movable plate 21. A fixed plate 23 is hinged to the end of the push plate 22 away from the movable plate 21. Magnetic blocks 24 are fixedly connected to the inner wall of the groove near the weight block 19 and the side of the fixed plate 23 away from the movable plate 21. The magnetic blocks 24 are magnetically connected to each other. The second electric push rod 18 is located between two adjacent telescopic cylinders 8. The top of the motor 20 is fixedly connected to the top inner wall of the weight block 19. The movable plate 21 is located at the top of the threaded rod. Both sides of the movable plate 21 are slidably connected to the inner wall of the weight block 19. The bottom of the fixed plate 23 is slidably connected to the bottom inner wall of the weight block 19.

[0035] When one side of float 1 is impacted by a strong water flow, causing float 1 to tilt, the second electric push rod 18 drives the weight block 19 to move, causing the magnetic block 24 of the fixed plate 23 to separate from the magnetic block 24 on the inner wall of the groove. This causes the weight block 19 to move in the opposite direction to the tilted side of float 1. After moving to the appropriate position, the motor 20 is simultaneously started to drive the threaded rod to rotate along the inner wall of the weight block 19. Since the movable plate 21 is slidably connected to the inner wall of the weight block 19 on both sides, the movable plate 21 moves along the threaded rod, thereby causing the push plate 22 to deflect. The push plate 22 pushes the fixed plate 23 to move along the bottom inner wall of the weight block 19, and pushes the fixed plate 23... The magnetic blocks 24 on the inner wall of the groove of the side magnetic block 24 are attracted to each other, thereby fixing the position of the weight block 19 after it has moved. By increasing the weight of the opposite side of the tilted side of the float block 1 through the weight block 19, the center of gravity of the float block 1 is shifted to counteract the tilting force of the float block 1 and achieve the purpose of balance. It can also make the overall force of the float block 1 more balanced, prevent the connection parts from loosening or breaking due to concentrated force, extend the service life of the float block 1, better adapt to these complex and changing environments, always maintain a relatively stable horizontal posture, avoid the float block 1 from tilting further or even overturning, and ensure the safety and stability of the float block 1, the planting board 2, the mounting pole and the photovoltaic panel 7.

[0036] Working principle of the invention: Referring to Figures 1 to 7, during use, the pressure sensor senses the pressure change on the float 1. When encountering areas with strong winds or rapid water flow, the first electric push rod 4 is activated, driving the moving plate 5 and planting plate 2 downwards, and causing the telescopic cylinder 8 to retract, thereby reducing the height of the planting plate 2, reducing the force-bearing area, and reducing the obstruction to water flow. When the planting plate 2 moves downwards, it drives the moving rod 13 and protrusion 14 downwards, causing the protrusion 14 to move downwards along the inclined surface of the limiting block 15 and squeeze the limiting block 15, causing the compression spring 16 to stretch. The two limiting blocks 15 drive the limiting rod 17 to move away from each other, so that the limiting rod 17 is inserted into the socket, thereby limiting the adjacent float 1. At the same time, when the water flow impacts the outside of the float 1, one side of the float 1... Moving towards the connecting block 3, since the connecting block 3 is located in the mounting groove and its upper and lower sides are slidably connected to the mounting groove, the mounting groove of one of the floats 1 moves along the upper and lower sides of the connecting block 3, causing the gear 11 to drive the rotating rod to rotate along the inner wall of the mounting groove, causing the second rack 10 to drive the other float 1 to move in the opposite direction to the first rack 9, and causing the buffer spring 12 to be compressed. At the same time, when the float 1 moves, it drives the moving plate 5 to move along the bottom of the planting plate 2, and drives the telescopic cylinder 8 and the moving ring 25 to move, causing the moving ring 25 to move in the annular groove. Through the relative movement of the first rack 9 and the second rack 10, the compression of the buffer spring 12 can disperse the force on the adjacent floats 1, so that the floats 1, the planting plate 2, the mounting rod and the photovoltaic panel 7 remain stable.

[0037] When one side of float 1 is impacted by a strong water flow, causing float 1 to tilt, the second electric push rod 18 drives the weight block 19 to move. This causes the magnetic block 24 of the fixed plate 23 to separate from the magnetic block 24 on the inner wall of the groove, allowing the weight block 19 to move in the opposite direction to the tilted side of float 1. After moving to the appropriate position, the motor 20 is simultaneously activated, causing the motor 20 to drive the threaded rod to rotate along the inner wall of the weight block 19. Since the movable plate 21 is slidably connected to the inner wall of the weight block 19 on both sides, the movable plate 21 moves along the threaded rod, thereby causing the push plate 22 to deflect. The push plate 22 pushes the fixed plate 23 to move along the bottom inner wall of the weight block 19 and pushes the fixed plate 23. The magnetic blocks 24 on one side of the magnetic block 24 are attracted to the inner wall of the groove, thereby fixing the position of the weight block 19 after it has moved. By increasing the weight of the opposite side of the tilted side of the float block 1 through the weight block 19, the center of gravity of the float block 1 is shifted to counteract the tilting force of the float block 1 and achieve balance. It can also make the overall force of the float block 1 more balanced, prevent the connection parts from loosening or breaking due to concentrated force, extend the service life of the float block 1, better adapt to these complex and changing environments, always maintain a relatively stable horizontal posture, prevent the float block 1 from tilting further or even overturning, and ensure the safety and stability of the float block 1, the planting board 2, the mounting rod and the photovoltaic panel 7.

[0038] Example 2: The present invention discloses a restoration method for the above-mentioned fish habitat restoration device, comprising the following steps: Step 1, device placement and initial fixation: The fish habitat restoration device is placed in the water body of the fish habitat to be restored. The device is floated and positioned by the float 1. The initial distribution of multiple floats 1 is fixed by the cooperation of the connecting column 26 and the connecting block 3; Step 2, environmental monitoring and height adjustment start-up: The pressure sensor on the float 1 senses the pressure change caused by water flow or waves. When the pressure reaches a preset threshold, the first electric push rod 4 is activated, driving the moving plate 5 to move the planting plate 2 downward, and simultaneously driving the telescopic extension. The cylinder 8 retracts, lowering the height of the planting plate 2 and reducing the area of ​​the device above the water surface exposed to wind and water flow resistance; Step 3, fixing the float and the planting plate: During the downward movement of the planting plate 2, the bottom moving rod 13 and the protrusion 14 move down synchronously. The protrusion 14 presses the two limiting blocks 15 along the inclined surface of the limiting block 15, causing the compression spring 16 to stretch. The two limiting blocks 15 drive the limiting rod 17 away from each other until the limiting rod 17 is inserted into the insertion hole in the inner wall of the limiting groove, completing the fixing of the float 1 and the planting plate 2; Step 4, impact force buffering and dispersion: When the water flow impacts the outside of the float 1, the adjacent float 1 moves towards the connecting block 3, and the floating block 1 is fixed. The groove slides along the upper and lower sides of the connecting block 3, driving the first rack 9 to move. The first rack 9 meshes with the driving gear 11 and the rotating rod to rotate. The gear 11 drives the second rack 10 to drive another float 1 to move in the opposite direction. At the same time, the buffer springs 12 on both sides of the connecting block 3 are compressed, which, together with the float 1, drives the moving plate 5 to slide along the bottom of the planting plate 2, and the telescopic cylinder 8 drives the moving ring 25 to move in the annular groove, realizing the dispersion and buffering of the impact force. Step 5, posture leveling and center of gravity fixation: When the device tilts, the second electric push rod 18 is activated to push the weight block 19 to move along the groove to the opposite side of the tilt direction of the float 1, adjusting the center of gravity of the device. After moving to the preset position, the motor 20 is started to drive the threaded rod to rotate, which drives the movable plate 21 to slide along the inner wall of the weight block 19. The movable plate 21 pushes the push plate 22 to deflect, which in turn pushes the fixed plate 23 to move towards the inner wall of the groove, so that the magnetic block 24 on one side of the fixed plate 23 is magnetically attracted to the magnetic block 24 on the inner wall of the groove, thus completing the fixation of the weight block 19 and realizing the horizontal attitude calibration of the device; Step 6, Continuous repair and maintenance: The aquatic purification plants in the planting port 6 absorb water pollutants and improve the eutrophication state of the water body; Regularly check the integrity of the float 1, replace the damaged float 1 individually, and maintain the continuous repair function of the device.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims.
