Description

Technical Field

[0001] This invention relates to the field of aquatic ecological restoration technology, and in particular to a device for the ecological restoration of fish habitats and its usage method. Background Technology

[0002] Aquatic ecological restoration of fish habitats is a crucial environmental protection effort. It aims to restore the natural ecological functions of damaged water bodies, provide a suitable living environment for fish and other aquatic organisms, and effectively improve water quality and enhance the self-purification capacity of water bodies by taking comprehensive measures such as water purification, aquatic vegetation restoration, and bottom sediment management. At the same time, it aims to rebuild a diverse aquatic ecosystem, increase fish food sources and shelters, and promote fish population reproduction and ecological balance.

[0003] With the large-scale discharge of industrial wastewater and domestic sewage, algae blooms and dissolved oxygen levels have decreased, threatening the survival of fish. To address this problem, the use of plant absorption for aquatic ecological restoration has become an effective means. By setting up floating boards on the water surface and planting plants with nutrient absorption capabilities, their roots extend into the water to effectively absorb excess nitrogen, phosphorus, and other nutrients, thereby reducing the degree of eutrophication.

[0004] To address eutrophication in fish habitats, floating slabs for planting have been used. However, to prevent collisions and facilitate nutrient absorption, the slabs need to be fixed and spaced out. Unfortunately, the slow flow of lake water makes it difficult to evenly distribute nutrients, resulting in slow absorption. Furthermore, the efficiency of nutrient absorption by plants gradually decreases during growth, necessitating harvesting or replanting when necessary, making the process cumbersome. Therefore, this paper proposes an ecological restoration device for fish habitats and its application method. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as slow lake water flow, difficulty in balancing nutrient accumulation in the water body by relying solely on water flow, resulting in slow absorption rates, and a gradual decrease in the efficiency of plant nutrient absorption during growth, requiring harvesting or replanting when a certain level is reached. The invention proposes a fish habitat aquatic ecological restoration device and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for ecological restoration of aquatic bodies in fish habitats and its method of use include a float plate. A cutting assembly is provided on the float plate, comprising a threaded rod and a raker rotatably connected to the upper part of the float plate, and a movable plate, a first blade, and a second blade movably connected to the upper part of the float plate. The forward and reverse rotation of the threaded rod causes the movable plate to move left and right. The leftward movement of the movable plate causes the raker to rotate, and the rotation of the raker agitates aquatic plants planted on the float plate, moving them closer to the movable plate. The rotation of the second blade cuts the aquatic plants at a fixed height, causing them to fall onto the upper part of the movable plate. The rotation of the first blade further shreds the fallen aquatic plants, throwing the shredded plants into the surrounding water. A moving assembly is provided on the float plate, comprising multiple propeller blades rotatably connected to the bottom of the float plate, and a third rotating rod and an L-shaped movable tube rotatably connected to the outer side of the float plate. The rotation of the third rotating rod drives the multiple propeller blades to rotate, and the rotation of the propeller blades on the bottom of the water propels the float plate to move. The rotation of the L-shaped movable tube changes the rotation angle of the propeller blades.

[0007] The above technical solution further includes: The upper part of the floating plate has multiple cultivation troughs, and multiple limiting tubes are fixedly connected to the upper part of the floating plate. A limiting plate is fixedly connected to the end of the limiting tube away from the floating plate. The limiting plate is fixedly connected to the floating plate. Solar panels are symmetrically fixedly connected to the upper part of the floating plate. Connecting blocks are fixedly connected to both sides of the floating plate. The limiting tubes have a guiding and gathering effect on the growth of aquatic plants.

[0008] A second motor is fixedly connected to the upper part of the float plate. A first belt is movably connected to the end of the output shaft of the second motor. The end of the first belt away from the second motor is movably connected to a second gear. A limit rod is fixedly connected to the side of the float plate close to the second motor. The second motor is started by driving the threaded rod to rotate through the first belt.

[0009] The floating plate is symmetrically fixedly connected to a rack on the side away from the second motor. The movable plate is threadedly connected to the threaded rod, the movable plate is slidably connected to the limiting rod, and the movable plate is movably connected to the pull rod. The forward and reverse rotation of the threaded rod causes the movable plate to slide left and right on the limiting rod.

[0010] Both sides of the derrick are fixedly connected to a first gear, which meshes with a rack. A first motor is fixedly connected inside the movable plate, and the derrick moves by rotating through the first gear and rack.

[0011] A second gear is fixedly connected to the output shaft end of the first motor, and a second rotating rod is rotatably connected to the outer side of the movable plate. The second rotating rod meshes with the second gear, and the second rotating rod is fixedly connected to the first blade. The start of the first motor drives the second gear to rotate.

[0012] The outer side of the second rotating rod is movably connected to a second belt, and the end of the second belt away from the second gear is movably connected to a first rotating rod. The first rotating rod is movably connected to the movable plate, and the first rotating rod is fixedly connected to the second blade. The rotation of the second gear drives the first rotating rod and the second blade to rotate through the second belt.

[0013] A third motor is fixedly connected to the upper part of the float plate. The output shaft end of the third motor is fixedly connected to the third rotating rod. The end of the third rotating rod away from the third motor is fixedly connected to the first helical gear. The start of the third motor drives the third rotating rod, and the third rotating rod drives the first helical gear to rotate.

[0014] A fourth motor is fixedly connected to the upper part of the float plate. A fourth gear is fixedly connected to the end of the output shaft of the fourth motor. A third gear is fixedly connected to the end of the L-shaped movable tube near the fourth motor. The third gear meshes with the fourth gear. The L-shaped movable tube is movably connected to the propeller blade. A second helical gear is fixedly connected to the end of the propeller blade near the first helical gear. The second helical gear meshes with the first helical gear. The rotation of the first helical gear drives the propeller blade to rotate through the second helical gear.

[0015] The present invention has the following beneficial effects: 0. In this invention, the moving plate is driven by the forward and reverse rotation of the threaded rod in the cutting assembly, which, together with the rotation of the rammer, moves the aquatic plants. Then, the second blade cuts the plants at a fixed height, and the first blade further shreds the plants and throws them around the water. This achieves efficient harvesting and shredding of aquatic plants, which not only simplifies the harvesting and replanting process, but also promotes the balanced distribution of nutrients in the water and improves the efficiency of ecological restoration.

[0016] 1. In this invention, the third rotating rod in the moving component drives multiple propeller blades to rotate at the bottom of the water, thereby pushing the float to move autonomously. This not only solves the problem of uneven nutrient absorption caused by slow lake water flow, but also adjusts the rotation angle of the propeller blades by rotating the L-shaped movable tube, realizing the flexible positioning and movement of the device in the water body, and improving the coverage and restoration efficiency of aquatic plants in eutrophic areas of the water body.

[0019] 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.

[0020] Example 1 like Figures 1-7As shown, the present invention proposes a fish habitat aquatic ecological restoration device, comprising a float 1, on which a cutting assembly is provided. The cutting assembly includes a threaded rod 6 and a raker 13 rotatably connected to the upper part of the float 1, and a movable plate 10, a first blade 4, and a second blade 5 movably connected to the upper part of the float 1. The forward and reverse rotation of the threaded rod 6 causes the movable plate 10 to move left and right. The leftward movement of the movable plate 10 causes the raker 13 to rotate. The rotation of the raker 13 agitates the aquatic plants planted on the float 1, causing the aquatic plants to move closer to the movable plate 10. The rotation of the second blade 5 affects the aquatic plants. The aquatic plants are cut at a fixed height, causing them to fall onto the upper part of the movable plate 10. The rotation of the first blade 4 further shreds the fallen aquatic plants and throws the shredded plants around the water. The float 1 is equipped with a moving component, which includes multiple propeller blades 30 rotatably connected to the bottom of the float 1, as well as a third rotating rod 27 and an L-shaped movable tube 23 rotatably connected to the outside of the float 1. The rotation of the third rotating rod 27 drives the multiple propeller blades 30 to rotate. The rotation of the propeller blades 30 on the bottom of the water pushes the float 1 to move. The rotation of the L-shaped movable tube 23 changes the rotation angle of the propeller blades 30.

[0021] Multiple cultivation troughs 9 are provided on the upper part of the floating plate 1. Multiple limiting tubes 7 are fixedly connected to the upper part of the floating plate 1. A limiting plate 8 is fixedly connected to the end of the limiting tube 7 away from the floating plate 1. The limiting plate 8 is fixedly connected to the floating plate 1. Solar panels 3 are symmetrically fixedly connected to the upper part of the floating plate 1. Connecting blocks 2 are fixedly connected to both sides of the floating plate 1. The limiting tubes 7 have a guiding and gathering effect on the growth of aquatic plants.

[0022] A second motor 18 is fixedly connected to the upper part of the float plate 1. A first belt 17 is movably connected to the end of the output shaft of the second motor 18. The end of the first belt 17 away from the second motor 18 is movably connected to the second gear 16. A limit rod 11 is fixedly connected to the side of the float plate 1 closest to the second motor 18. The start of the second motor 18 drives the threaded rod 6 to rotate through the first belt 17.

[0023] A rack 12 is symmetrically fixed to the side of the float 1 away from the second motor 18. The movable plate 10 is threadedly connected to the threaded rod 6. The movable plate 10 is slidably connected to the limiting rod 11. The movable plate 10 is movably connected to the pull rod 13. The forward and reverse rotation of the threaded rod 6 causes the movable plate 10 to slide left and right on the limiting rod 11.

[0024] Both sides of the derrick 13 are fixedly connected to the first gear 14, which meshes with the rack 12. The movable plate 10 is fixedly connected to the first motor 15. The movement of the derrick 13 is achieved by rotating the first gear 14 and the rack 12.

[0025] The output shaft of the first motor 15 is fixedly connected to the second gear 16, and the outer side of the movable plate 10 is rotatably connected to the second rotating rod 26. The second rotating rod 26 meshes with the second gear 16, and the second rotating rod 26 is fixedly connected to the first blade 4. The start of the first motor 15 drives the second gear 16 to rotate.

[0026] The outer side of the second rotating rod 26 is movably connected to the second belt 24. The end of the second belt 24 away from the second gear 16 is movably connected to the first rotating rod 25. The first rotating rod 25 is movably connected to the movable plate 10. The first rotating rod 25 is fixedly connected to the second blade 5. The rotation of the second gear 16 drives the first rotating rod 25 and the second blade 5 to rotate through the second belt 24.

[0027] In this embodiment, all materials used in the device are lightweight. Aquatic plants are cultivated in the cultivation trough 9. The limiting tube 7 guides and gathers the growth of aquatic plants. The limiting plate 8 serves as the fixed position for cutting aquatic plants. The solar panel 3 collects the electrical energy of the device. When the aquatic plants grow too tall and need to be harvested, the second motor 18 is started, driving the threaded rod 6 to rotate via the first belt 17. The forward and reverse rotation of the threaded rod 6 causes the movable plate 10 to slide left and right on the limiting rod 11. When the movable plate 10 moves towards the solar panel 3, it drives the raker 13 to move accordingly. The movement of the raker 13 is driven by the rotation of the first gear 14 and the rack 12. During the movement, the raker 13 pushes the aquatic plants towards the movable plate 10. As the plants approach, the first motor 15 starts, driving the second gear 16 to rotate. The rotation of the second gear 16 drives the first rotating rod 25 and the second blade 5 to rotate via the second belt 24. This causes the second blade 5 to cut the aquatic plants, causing the aquatic plants pushed by the lever 13 to fall onto the movable plate 10. At this time, the rotation of the second gear 16 drives the second rotating rod 26 to rotate, which in turn drives the first blade 4 to rotate. The rotation of the first blade 4 cuts and shreds the aquatic plants that have fallen onto the movable plate 10, and throws the shredded aquatic plants around the water. When the movable plate 10, along with the first blade 4 and the second blade 5, has finished cutting the aquatic plants, the reverse rotation of the threaded rod 6 causes the movable plate 10 to return to its original position, ready for the next harvest.

[0028] Example 2 like Figures 1-7 As shown, based on Embodiment 1, a third motor 19 is fixedly connected to the upper part of the float 1. The output shaft end of the third motor 19 is fixedly connected to the third rotating rod 27. The end of the third rotating rod 27 away from the third motor 19 is fixedly connected to the first helical gear 28. The start of the third motor 19 drives the third rotating rod 27, and the third rotating rod 27 drives the first helical gear 28 to rotate.

[0029] A fourth motor 20 is fixedly connected to the upper part of the float 1. A fourth gear 22 is fixedly connected to the end of the output shaft of the fourth motor 20. A third gear 21 is fixedly connected to the end of the L-shaped movable tube 23 near the fourth motor 20. The third gear 21 meshes with the fourth gear 22. The L-shaped movable tube 23 is movably connected to the propeller blade 30. A second helical gear 29 is fixedly connected to the end of the propeller blade 30 near the first helical gear 28. The second helical gear 29 meshes with the first helical gear 28. The rotation of the first helical gear 28 drives the propeller blade 30 to rotate through the second helical gear 29.

[0030] In this embodiment, as described in the previous step, the start of the third motor 19 drives the third rotating rod 27, which in turn drives the first helical gear 28 to rotate. The rotation of the first helical gear 28 drives the propeller blade 30 to rotate via the second helical gear 29. The start of the fourth motor 20 drives the fourth gear 22 to rotate, which in turn drives the L-shaped movable tube 23 to move left and right via the third gear 21. The left and right movement of the L-shaped movable tube 23 drives the propeller blade 30 to follow the movement, thereby moving the aquatic plants on the float 1 and making them float in the water. During the movement of the float 1, the first blade 4 throws out the crushed aquatic plants, so that the crushed aquatic plants are evenly sprinkled on the water surface.
