Description

Technical Field

[0001] The present invention relates to the field of water body ecological restoration devices, and specifically refers to a water body ecological restoration device for fish habitats. Background Art

[0002] Fish are the most ancient vertebrates, and they inhabit almost all aquatic environments on the earth - from fresh water lakes and rivers to salt water seas and oceans. With the development of industrial and agricultural production, urban expansion, and the discharge of land-based pollutants, the fishery ecological environment has been severely damaged: industrial wastewater, domestic sewage, agricultural return water (including chemical fertilizers), and livestock manure, etc., can all cause water eutrophication. Water eutrophication refers to the phenomenon that a large amount of nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies, causing the rapid reproduction of algae and plankton, resulting in a decrease in the dissolved oxygen content in the water body, and a large number of fish and other organisms die. A large number of dead aquatic organisms deposit at the bottom of the water body and are decomposed by microorganisms, consuming a large amount of dissolved oxygen, causing the dissolved oxygen content in the water body to decrease sharply, deteriorating the water quality, and thus affecting the survival of fish.

[0003] Currently, the eutrophication problem of fish habitats is generally solved by plant absorption, which is low-cost and environmentally friendly. By setting floating plates on the water surface and planting plants on the floating plates, part of their roots enter the water body, and part of the roots are in the planting frames on the floating plates to fix the plants. The roots located inside the water body can absorb the excess nutrients in the water body to solve the eutrophication of fish habitats.

[0004] However, in order to prevent the floating plates from colliding with each other and causing damage to the floating plates or the planted plants from toppling, the floating plates generally need to be fixed. And in order to better absorb the eutrophication in the water body, the floating plates generally need to be set at a certain interval. Therefore, the enriched nutrients in the water body are balanced only by the flow of the water itself. Since the water flow in the lake is relatively slow, the absorption rate is slow. When the plants grow to a certain extent, the efficiency of absorbing nutrients will decrease, so they need to be harvested or replanted, which is rather troublesome. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above deficiencies and provide a water body ecological restoration device for fish habitats to solve the technical problem that when the existing water body ecological restoration device for fish habitats is in use, the enriched nutrients in the water body are balanced only by the flow of the water itself, and since the water flow in the lake is relatively slow, the absorption rate is slow. When the plants grow to a certain extent, the efficiency of absorbing nutrients will decrease, so they need to be harvested or replanted, which is rather troublesome.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a water ecological restoration device for fish habitats, including a fixed column, an installation frame is connected to the fixed column, and a floating plate is detachably connected to the edge of the installation frame. A sleeve is sleeved on the fixed column, and a plurality of steel wires are connected to the outer edge of the sleeve. A driving mechanism cooperating with the sleeve is installed inside the fixed column, and a fine-thread external thread cooperating with the inner side of the sleeve is arranged on the outer surface of the fixed column. A water deflecting mechanism cooperating with the driving mechanism is arranged below the installation frame on the fixed column.

[0007] Preferably, the driving mechanism includes a driving motor and a first gear. The driving motor is installed inside the fixed column, and the output end of the driving motor is connected to a first gear meshing with the vertical rack on the inner side of the sleeve. The vertical racks are arranged in a circular array on the inner side of the sleeve and mesh with the teeth on the side of the first gear. The inner surface of the vertical rack is provided with an internal thread cooperating with the fine-thread external thread.

[0008] Preferably, the water deflecting mechanism includes a bevel gear, a round wheel, a synchronous belt, a transmission rod, a connecting rod, a movable block, a connecting block, a water deflecting plate, a piston plate and a water outlet. A bevel gear meshing with the lower side of the first gear is rotatably connected inside the fixed column, and a round wheel is rotatably connected to both sides inside the fixed column respectively. A synchronous belt is sleeved on the rotating shaft of the bevel gear and one of the round wheels. The eccentric positions of the two round wheels are connected by an eccentric shaft. A transmission rod is rotatably connected to the eccentric shaft, and the other end of the transmission rod is rotatably connected to a connecting rod slidably connected inside the fixed column. The other end of the connecting rod is connected to a movable block. A plurality of water deflecting plates are rotatably connected to the outer wall of the fixed column, and a connecting block is rotatably connected between the movable block and each water deflecting plate. A cavity is arranged inside the fixed column, and the bottom surface of the movable block is connected to a piston plate in the cavity of the fixed column through a piston rod. A plurality of uniformly arranged water outlets are opened at the bottom end of the cavity on the outer surface of the fixed column.

[0009] Preferably, an air pump with an input end at the top of the fixed column is installed inside the fixed column, and the output end of the air pump is connected to a gas distribution plate.

[0013] Preferably, a plurality of planting frames are evenly arranged on each floating board, and the planting frames are in a net structure woven from a material that does not release toxic substances.

[0014] Advantages of the present invention: By rotatably connecting a sleeve on a fixed column, connecting a steel wire rope cooperating with the floating board on the sleeve, and providing a water deflecting mechanism on the fixed column, when the grass on the floating board grows to a certain height, the sleeve rotates and slowly descends, driving the steel wire rope to rotate rapidly, breaking the grass from top to bottom, and throwing it into the water as fish feed by the centrifugal force of the steel wire rope. At the same time, the water deflecting mechanism diffuses the fish feed outward, which is more convenient. When the water deflecting mechanism diffuses the grass particles outward, it can also drive the nutrient exchange in the water, with higher cleaning efficiency. It solves the technical problem that when using the existing water body ecological restoration device for fish habitats, the enrichment of nutrients in the water body depends solely on the flow of the water itself for balance, and the water flow in the lake is relatively slow, resulting in a slow absorption rate. When the plants grow to a certain extent, the nutrient absorption efficiency will decline, so harvesting or replanting is required, which is rather troublesome. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, according to the overall structure of the present invention, its embodiments will be described.

[0034] An ecological restoration device for fish habitat water body, as Figures 1 - 8As shown in the figure, it includes a fixed column 1 and a floating plate 3. The bottom end of the fixed column 1 is slidably connected to an installation column 23. During use, the fixed column 1 is installed and fixed at the bottom of the water through the installation column 23. An installation frame 2 is connected to the fixed column 1, and then the floating plate 3 is connected to the edge of the installation frame 2. A plurality of planting frames 4 are evenly arranged on each floating plate 3. Aquatic plants that can be directly used as fish feed can be planted in the planting frames 4. A sleeve 5 is sleeved on the fixed column 1. The outer surface of the fixed column 1 is provided with fine threads that cooperate with the sleeve 5. Multiple steel wire ropes 6 are connected to the outer edge of the sleeve 5. A driving mechanism that cooperates with the sleeve 5 is installed inside the fixed column 1. When the aquatic plants grow to a certain height, the operator starts the driving mechanism to drive the sleeve 5 to rotate at a high speed, and at the same time, it slowly descends in cooperation with the fine external threads, driving the steel wire ropes 6 to break the aquatic plants from the top down and throwing them into the water by centrifugal force. And a water deflecting mechanism that cooperates with the driving mechanism is provided on the fixed column 1 below the installation frame 2. At the same time, the deflecting mechanism is driven by the driving mechanism to work and deflect the water, generating outward-diffusing water waves to drive the diffusion of the aquatic plant particles and prevent the accumulation of the aquatic plant particles, so as to better feed the fish.

[0035] Among them, the planting frame 4 is a net structure woven from a material that will not precipitate toxic substances, preventing the planting frame 4 from soaking in water for a long time and precipitating toxic substances, which may cause further pollution of the water body. And the net structure is convenient for the plant roots to extend. The installation column 23 is slidably connected to the fixed column 1, so that the fixed column 1 can rise and fall with the floating plate 3 along with the water waves, preventing the plant roots from separating from the water surface. The lowest point where the sleeve 5 can descend is higher than the top surface of the floating plate 3, preventing the steel wire ropes 6 from damaging the floating plate 3 when rotating at a high speed.

[0036] Furthermore, a detector can be set on the fixed column 1 to automatically start the driving mechanism for cleaning when the aquatic plants grow to block the detector.

[0037] The specific structure of the driving mechanism is as shown in Figure 6 and 7 As shown in the figure, a driving motor 7 is installed inside the fixed column 1, and the output end of the driving motor 7 is connected to a first gear 8 that meshes with the vertical rack on the inner side of the sleeve 5. The vertical racks are annularly arranged on the inner side of the sleeve 5 and mesh with the teeth on the side of the first gear 8. The inner surface of the vertical rack is provided with internal threads that cooperate with the fine external threads. The driving motor 7 can drive the sleeve 5 to rotate at a high speed through the first gear 8.

[0038] The specific structure of the water deflecting mechanism is as shown in Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, a bevel gear 9 that meshes with the lower side of the first gear 8 is rotatably connected inside the fixed column 1, and a round wheel 10 is rotatably connected inside the fixed column 1. A synchronous belt 11 is sleeved on the rotating shaft of the bevel gear 9 and the round wheel 10. A transmission rod 12 is rotatably connected to the eccentric shaft at the eccentric position of the round wheel 10, and the other end of the transmission rod 12 is rotatably connected to a connecting rod 13 that is slidably connected to the fixed column 1. The other end of the connecting rod 13 is connected to a movable block 14. A plurality of water deflecting plates 16 are rotatably connected to the outer wall of the fixed column 1, and a connecting block 15 is rotatably connected between the movable block 14 and each water deflecting plate 16. When the first gear 8 rotates to drive the bevel gear 9 to rotate, the round wheel 10 can be driven to rotate through the synchronous belt 11. Then, the movable block 14 can be driven to move up and down through the transmission rod 12 and the connecting rod 13. Furthermore, the water deflecting plates 16 can be driven to move up and down through the connecting blocks 15 for water deflection. A cavity is provided inside the fixed column 1, and a piston plate 17 that cooperates with the cavity inside the fixed column 1 is connected to the bottom surface of the movable block 14. A plurality of uniformly arranged water outlets 18 are provided at the bottom end of the cavity on the outer surface of the fixed column 1. When the movable block 14 moves up and down, the piston plate 17 can also be driven to perform a piston motion, and the water in the cavity is extruded through the water outlets 18 to form a faster outward driving force. The outward driving force generated by the water deflecting plates 16 is less than the outward driving force generated by the piston plate 17, and the outward driving force at the lower part is greater than the driving force at the upper part, so that the waterweed particles can be diffused over a longer distance. Moreover, the driving force generated by the piston plate 17 is reciprocating, and the waterweed particles can be pulled back and forth, which can also prevent the waterweed particles from aggregating and keep them dispersed.

[0039] In order to better improve the water environment, an air pump 19 with an input end located at the top of the fixed column 1 is installed inside the fixed column 1, and a gas distribution plate 20 is connected to the output end of the air pump 19. A plurality of vertical aeration pipes 21 are connected to the gas distribution plate 20, and a plurality of small holes are provided on the side surface of the aeration pipes 21. The air pump 19 sucks in the outside air, which enters the aeration pipes 21 through the distribution of the gas distribution plate 20 and is ejected through the small holes of the aeration pipes 21 to increase the oxygen content in the water body. At the same time, the air ejected from the aeration pipes 21 can also push the water flow to diffuse outward, thereby driving the diffusion of the waterweed particles.

[0040] In order to facilitate the replacement and cleaning of the floating plate 3, the floating plate 3 and the installation frame 2 are connected to each other through a detachable connector 24 with a threaded connection. When the floating plate 3 needs to be disassembled, only by rotating the detachable connector 24 to disengage from the floating plate 3 can the floating plate 3 be removed.

[0041] A storage battery is installed inside the installation column 23, and a solar panel 22 is provided on the top surface of the fixed column 1. The solar panel 22 generates electricity, and the electricity is stored by the storage battery to supply power to the device.

[0042] In use, the fixed vertical column 1 is installed and fixed on the bottom of the water through the installation column 23, and then the floating board 3 is connected to the edge of the installation frame 2. Then, aquatic plants that can be directly used as fish feed can be planted in the planting frame 4. When the aquatic plants grow to a certain height, the operator starts the driving motor 7. The first gear 8 drives the sleeve 5 to rotate at a high speed, and at the same time, it slowly descends in cooperation with the fine-thread external thread, which can drive the steel wire rope 6 to rotate and descend at a high speed to break the aquatic plants from the top downwards, and fling them into the water by centrifugal force. When the first gear 8 rotates, it can drive the bevel gear 9 to rotate, and then the synchronous belt 11 drives the round wheel 10 to rotate. Through the transmission rod 12 and the connecting rod 13, the movable block 14 can be driven to move up and down, so that the connecting block 15 drives the water deflecting plate 16 to move up and down to deflect the water. When the movable block 14 moves up and down, it can also drive the piston plate 17 to perform a piston motion, and squeeze the water in the cavity out through the water outlet 18 to form a faster outward driving force to spread the aquatic plant particles outwards. When the sleeve 5 descends to the lowest point, the driving motor 7 reverses to drive the sleeve 5 to reset.

The embodiments in this application and the features in the embodiments can be arbitrarily combined with each other without conflict. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
