Description

Technical Field

[0001] This utility model relates to the field of floating bed technology, and in particular to a floating bed for the remediation of eutrophication in water bodies. Background Technology

[0002] Floating beds for eutrophication remediation are artificial ecosystem carriers placed on the water surface. Their main function is to support aquatic plants, which absorb nutrients such as nitrogen and phosphorus from the water through their roots, reducing nutrient concentration and inhibiting algal growth. Simultaneously, the roots can attach microorganisms, forming a biofilm that decomposes organic pollutants and purifies the water. The floating beds also block some sunlight, reducing light entering the water and limiting algal photosynthesis, thus mitigating algal blooms. Furthermore, the floating structure stabilizes the surface environment, provides habitat for small aquatic organisms, improves the aquatic ecosystem structure, and promotes ecological balance restoration. They require no large-scale underwater construction and can be flexibly deployed in lakes, reservoirs, rivers, and other water bodies. Through continuous ecological action, they gradually improve eutrophication and enhance the water body's self-purification capacity.

[0003] Currently, existing ecological restoration devices for eutrophic water bodies (such as announcement number: CN218810851U) disclose ecological restoration devices for eutrophic water bodies, involving the field of ecological restoration technology. These devices include an ecological restoration bed, an ecological restoration plant cultivation trough, a front-turning roller, and a rear-turning roller. The ecological restoration bed has a front-turning roller installed at the front and a rear-turning roller installed at the rear. Left and right fixed rods are fixed to both sides of the ecological restoration bed, and multiple sets of ecological restoration plant cultivation troughs are installed between the left and right fixed rods on the same side. A left side plate is provided at the left end of the ecological restoration bed, and a left solid buoyancy seat is provided inside the left side plate. A right side plate is provided at the right end of the ecological restoration bed. This invention facilitates the planting of large plants for eutrophic water body restoration and can promote rapid water flow near both ends of the restoration device, increasing contact between the plants and the water. Furthermore, it easily promotes rapid water flow, which helps to accelerate the restoration of eutrophic water bodies.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0005] Floating plants, such as reeds and canna lilies, are the core tools for the remediation of eutrophication in water bodies. They absorb nutrients such as nitrogen and phosphorus from the water through their roots and fix carbon through photosynthesis, thereby reducing the degree of eutrophication. However, if the plants are not harvested in time after they reach maturity, the residues such as leaves, stems and roots will gradually wither, fall off and sink into the water. Through the decomposition process of microorganisms, they release a large amount of pollutants, forming "secondary pollution" and even negating the previous remediation effect. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a floating bed for eutrophication remediation. Floating bed plants, such as reeds and canna lilies, are the core tools for eutrophication remediation. They absorb nutrients such as nitrogen and phosphorus from the water through their roots and fix carbon through photosynthesis, thereby reducing the degree of eutrophication. However, if the plants are not harvested in time after reaching maturity, the residues such as leaves, stems, and roots will gradually wither, fall off, and sink into the water. Through microbial decomposition, they release a large amount of pollutants, causing "secondary pollution" and even negating the initial remediation effects.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A floating bed for eutrophication remediation includes a main body of the device, an isolation mechanism at the lower end of the main body including a waterproof covering cloth, a fixed frame fixedly connected to the lower end of the main body, a U-shaped movable block inside the fixed frame, a covering frame fixedly connected to the left surface of the fixed frame, the waterproof covering cloth located inside the covering frame, a winding roller inside the covering frame, and the waterproof covering cloth wrapped around the surface of the winding roller.

[0009] Preferably, the right end of the waterproof covering cloth passes through the fixed frame and is fixedly connected to the U-shaped movable block.

[0010] Preferably, the fixed frame is provided with a threaded rod inside, both ends of which are rotatably connected to the inner wall of the fixed frame, and the U-shaped moving block is threadedly sleeved with the threaded rod.

[0011] Preferably, both ends of the U-shaped movable block are fitted with limiting slide rods, and both ends of the two limiting slide rods are fixedly connected to the inner wall of the fixed frame.

[0012] Preferably, a motor is fixedly connected to the right surface of the fixed frame, and the output port of the motor passes through the fixed frame and is fixedly connected to the threaded rod.

[0013] Preferably, torsion springs are fitted at both ends of the winding roller, with the opposite ends of the two torsion springs fixedly connected to the winding roller, and the opposite ends of the two torsion springs fixedly connected to the inner wall of the cover frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the plants on the main body of the device begin to rot, the motor is started. The motor drives the threaded rod to rotate, and the U-shaped moving block moves along the trajectory of the two limit sliding rods. The U-shaped moving block then moves the waterproof covering cloth, which continuously covers the lower end of the main body of the device as it moves, until the U-shaped moving block moves to the right end of the inner wall of the fixed frame. At this point, the waterproof covering cloth will completely cover the lower end of the main body of the device, preventing the plants from being left unharvested after reaching maturity, which would cause the plant debris to gradually wither, fall off, and sink into the water, thus avoiding "secondary pollution" and ensuring that the restoration effect is not affected.

[0016] 2. When the U-shaped moving block drives the waterproof covering cloth to unfold and cover the lower end of the device body, the winding roller will rotate accordingly. At this time, the torsion spring will deform due to the rotation of the winding roller and store elastic potential energy. When it is necessary to retract the waterproof covering cloth, the torsion spring releases the elastic potential energy, driving the winding roller to rotate in the opposite direction, thereby automatically winding up the waterproof covering cloth. No additional power is needed to drive the winding process, saving energy consumption. The torsion spring can always apply a certain torque to the winding roller, so that the waterproof covering cloth always maintains appropriate tension during unfolding and winding, avoiding the waterproof covering cloth from becoming loose, wrinkled or excessively tight, and ensuring the tightness and stability of the waterproof covering cloth covering the lower end of the device body.

[0023] This application provides a floating bed for eutrophication remediation, effectively addressing the problem that floating bed plants, such as reeds and canna lilies, are the core tools for eutrophication remediation. These plants absorb nutrients such as nitrogen and phosphorus from the water through their roots and fix carbon through photosynthesis, thereby reducing the degree of eutrophication. However, if the plants are not harvested in time after reaching maturity, their remains, such as leaves, stems, and roots, will gradually wither, fall off, and sink into the water. Through microbial decomposition, they release a large amount of pollutants, forming "secondary pollution" and even negating the previous remediation effects.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively addresses the problem that floating plants, such as reeds and canna lilies, are core tools for eutrophication remediation. These plants absorb nutrients like nitrogen and phosphorus from the water through their roots and fix carbon through photosynthesis, thereby reducing eutrophication. However, if these plants are not harvested in time after reaching maturity, their remains, such as leaves, stems, and roots, will gradually wither, fall off, and sink into the water, releasing large amounts of pollutants through microbial decomposition, causing "secondary pollution" and even negating the initial remediation effects. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a floating bed for eutrophication remediation of water bodies, including a main body 11. An isolation mechanism, including a waterproof covering cloth 19, is provided at the lower end of the main body 11. A fixed frame 12 is fixedly connected to the lower end of the main body 11. A U-shaped moving block 14 is provided inside the fixed frame 12. A covering frame 13 is fixedly connected to the left surface of the fixed frame 12. The waterproof covering cloth 19 is located inside the covering frame 13. A winding roller 20 is provided inside the covering frame 13. The waterproof covering cloth 19 is wound around the surface of the winding roller 20. The right end of the waterproof covering cloth 19 passes through the fixed frame 12 and is fixedly connected to the U-shaped moving block 14. A threaded rod 1 is provided inside the fixed frame 12. 7. Both ends of the threaded rod 17 are rotatably connected to the inner wall of the fixed frame 12. The U-shaped moving block 14 is threadedly connected to the threaded rod 17. Both ends of the U-shaped moving block 14 are fitted with limiting slide rods 16. Both ends of the two limiting slide rods 16 are fixedly connected to the inner wall of the fixed frame 12. When the U-shaped moving block 14 drives the waterproof covering cloth 19 to unfold to cover the lower end of the main body 11 of the device, the winding roller 20 will rotate accordingly. At this time, the torsion spring 15 will deform due to the rotation of the winding roller 20 and store elastic potential energy. When it is necessary to retract the waterproof covering cloth 19, the torsion spring 15 releases the elastic potential energy, drives the winding roller 20 to rotate in the opposite direction, thereby automatically winding up the waterproof covering cloth 19 without the need for additional power to drive the winding process.

[0027] When the plants on the main body 11 of the device begin to rot, the motor 18 is started. The motor 18 drives the threaded rod 17 to rotate, and the U-shaped moving block 14 moves along the trajectory of the two limit sliding rods 16. The U-shaped moving block 14 then drives the waterproof covering cloth 19 to move. As the waterproof covering cloth 19 moves, it continuously covers the lower end of the main body 11 of the device until the U-shaped moving block 14 moves to the right end of the inner wall of the fixed frame 12. At this point, the waterproof covering cloth 19 will completely cover the lower end of the main body 11 of the device, thus preventing the plant residue from gradually withering, falling off, and sinking into the water after it has grown to maturity and is not harvested in time, thus avoiding the problem of "secondary pollution" and ensuring that the restoration effect is not affected.

[0028] A motor 18 is fixedly connected to the right surface of the fixed frame 12. The output port of the motor 18 passes through the fixed frame 12 and is fixedly connected to the threaded rod 17. Both ends of the winding roller 20 are fitted with torsion springs 15. The opposite ends of the two torsion springs 15 are fixedly connected to the winding roller 20, and the opposite ends of the two torsion springs 15 are fixedly connected to the inner wall of the cover frame 13. This saves energy consumption. The torsion springs 15 can always apply a certain torque to the winding roller 20, so that the waterproof cover cloth 19 always maintains appropriate tension during the unfolding and winding process, avoiding the waterproof cover cloth 19 from becoming loose, wrinkled or overly tight, and ensuring the tightness and stability of the waterproof cover cloth 19 covering the lower end of the device body 11.

[0029] Working principle:

[0030] In the first step, when the plants on the main body 11 of the device begin to rot, the motor 18 is started. The motor 18 drives the threaded rod 17 to rotate, and the U-shaped moving block 14 moves along the trajectory of the two limit sliding rods 16. The U-shaped moving block 14 then drives the waterproof covering cloth 19 to move. As the waterproof covering cloth 19 moves, it continuously covers the lower end of the main body 11 of the device until the U-shaped moving block 14 moves to the right end of the inner wall of the fixed frame 12. At this point, the waterproof covering cloth 19 will completely cover the lower end of the main body 11 of the device, thus preventing the plants from being left unharvested after reaching maturity, causing the plant debris to gradually wither, fall off, and sink into the water, resulting in "secondary pollution" and ensuring that the restoration effect is not affected.

[0031] In the second step, when the U-shaped moving block 14 drives the waterproof covering cloth 19 to unfold and cover the lower end of the device body 11, the winding roller 20 will rotate accordingly. At this time, the torsion spring 15 will deform and store elastic potential energy due to the rotation of the winding roller 20. When it is necessary to retract the waterproof covering cloth 19, the torsion spring 15 releases the elastic potential energy, driving the winding roller 20 to rotate in the opposite direction, thereby automatically winding up the waterproof covering cloth 19. No additional power is needed to drive the winding process, saving energy consumption. The torsion spring 15 can always apply a certain torque to the winding roller 20, so that the waterproof covering cloth 19 always maintains appropriate tension during unfolding and winding, avoiding the waterproof covering cloth 19 from becoming loose, wrinkled or overly tight, and ensuring the tightness and stability of the waterproof covering cloth 19 covering the lower end of the device body 11.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
