Description

Technical Field

[0001] This invention relates to the field of water environment management technology, and more specifically, to an aquatic biological ecological restoration system and its construction method. Background Technology

[0002] With rapid industrialization and urbanization, large amounts of pollutants are discharged into water bodies, leading to eutrophication, water quality deterioration, and severe damage to the habitats of aquatic organisms. The ecological balance is now in jeopardy. To improve this situation, aquatic organism ecological restoration technologies have emerged, with the construction of suitable habitats for aquatic life being a crucial element.

[0003] In past practices of aquatic ecological restoration, artificial fish nests have often been installed in water bodies to provide habitats and breeding grounds for aquatic organisms. However, traditional artificial fish nest installation methods have many drawbacks. On the one hand, the assembly process is cumbersome and complex, requiring a significant amount of manpower and time. Installers need to use various tools and follow specific sequences and steps to assemble the nests, which is not only inefficient but also prone to errors, affecting the overall structure and stability of the nests. On the other hand, traditional installation methods cannot guarantee the stability of the nests after installation. Under the influence of water flow impacts and external collisions, the nests are prone to shaking or displacement. This not only damages the growth environment of algae and other aquatic organisms attached to the nest surface but may also damage the nests and reduce their lifespan. Furthermore, traditional artificial fish nest equipment is usually only compatible with bamboo fish baskets of a single size, lacking flexibility. In actual ecological restoration projects, different aquatic environments and restoration stages require fish baskets of different sizes to meet the growth needs of aquatic organisms, which traditional equipment cannot meet, thus limiting the effectiveness of ecological restoration.

[0004] In view of this, we propose an aquatic biological ecological restoration system and its construction method. Summary of the Invention

[0005] The purpose of this invention is to provide an aquatic organism ecological restoration system and construction method to solve the technical problems in traditional aquatic organism ecological restoration, such as the cumbersome and time-consuming assembly of artificial fish nests, the susceptibility to errors affecting structural stability, the difficulty in ensuring stability after installation, the easy displacement and damage to the fish nests due to water flow and external forces, and the fact that the equipment can only be adapted to a single size fish basket, lacking flexibility and limiting the restoration effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an aquatic organism ecological restoration system and its construction method, comprising the following restoration steps:

[0007] S1. Constructing bamboo fish baskets and establishing ecological niches.

[0008] Installing floating and submerged fish nest structures in the water provides growth surfaces and habitats for aquatic organisms. The surface of the fish nests can be used for algae and other aquatic organisms to attach and grow, forming a small ecosystem. This step is the foundation of the entire restoration process and provides ecological support for subsequent steps.

[0009] S2, Introduction of basic aquatic organisms

[0010] Introducing small aquatic organisms with strong reproductive capabilities, such as freshwater shrimp, allows them to quickly occupy ecological niches and increase biodiversity. Freshwater shrimp can not only provide a food source for large fish, but also reduce pollutants in the water by consuming organic detritus.

[0011] S3, Release fish and insects

[0012] Gradually introduce fish that feed on juvenile shrimp and cladocerans, such as the Yunnan schizothorax, to form the upper structure of the food chain. At the same time, introduce aquatic insects to provide biological food and promote fish growth. The introduction of fish and insects helps to establish a complex food web and enhance the stability of the ecosystem.

[0013] S4. Protect juvenile fish and benthic animals

[0014] Setting up juvenile fish sanctuaries protects them from predators and increases their survival rate. At the same time, it provides shelter for shrimp, crabs, and snails, promoting the reproduction of benthic animals. These benthic animals help reduce sediment resuspension and improve water clarity by feeding on organic matter in the bottom sediment.

[0015] S5, Promotes aquatic plant recovery

[0016] Through the above steps, the water transparency is improved, the light conditions are improved, and the recovery and growth of aquatic plants are promoted. Aquatic plants not only provide habitats for aquatic organisms, but also absorb nutrients from the water, further purifying the water quality.

[0017] In step S1, the floating fish nest mechanism is connected to the bottom-dwelling fish nest mechanism via a connecting rope.

[0018] The floating fish nest mechanism includes a frame assembly, a floating body assembly connected to the frame assembly, four No. 1 fish nests and four No. 2 fish nests connected to the floating body assembly, an adjustment assembly connected to the frame assembly, a limiting assembly connected to the adjustment assembly, several metal plates disposed above the frame assembly, an adsorption assembly, and a guide cylinder, wherein the adsorption assembly is connected to the adjustment assembly, and the guide cylinder is located outside the adjustment assembly.

[0019] This invention maintains a stable posture even under water flow impact or water level fluctuations, effectively preventing the fish nest structure from overturning or shifting. At the same time, the magnetic plate will also come into contact with the metal to complete the secondary fixation of the squeezing rod, further enhancing the overall structure's resistance to disturbances. This ensures that the fish nest remains stably suspended for a long time under complex hydrological conditions such as wind, waves, water flow, and frequent changes in water level. The dual insurance mechanism of magnetic attraction and mechanical means significantly improves the locking reliability and avoids the risk of device loosening due to single-point failure.

[0036] A method for constructing an aquatic biological ecological restoration system includes the following construction steps:

[0037] A1. The deployment of floating fish nest mechanisms and bottom-dwelling fish nest mechanisms requires positioning them in the water area using a positioning device at the designated location. The deployment of floating fish nest mechanisms and bottom-dwelling fish nest mechanisms should be carried out by professional personnel.

[0038] A2. Floating fish nest mechanisms and sinking fish nest mechanisms must not be exposed to the air. It is necessary to ensure that all fish nests and floats are completely submerged in water to reduce unnecessary fry and fish egg deaths and increase the hatching base of fish eggs and the survival rate of fish fry.

[0039] A3. Regular inspections and maintenance of the floating fish nest mechanism and the bottom-dwelling fish nest mechanism are required, especially when the water level changes significantly, the height of the cable should be adjusted in a timely manner and corresponding monitoring should be carried out.

[0040] A4. When in use, place the entire floating fish nest mechanism and the bottom-dwelling fish nest mechanism in a shallow lake. The floating fish nest mechanism and the bottom-dwelling fish nest mechanism will remain suspended in the water for a long time without affecting the appearance of the entire water area.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. This invention, through the design of an adjustment component, a metal plate, a frame component, and a limiting component, allows the smaller diameter portions of fish nests one and two to be inserted into the mounting frame and pass through the mounting ring via a hollowed-out position above the mounting frame. As fish nests one and two gradually extend, they gradually come into contact with the inner wall of the limiting ring. At this point, by continuously pushing fish nests one and two, they are completely inserted through the mounting plate and no longer in contact with the baffle. The baffle then naturally returns to its original position under gravity, while the elastic telescopic rod pulls the limiting ring and fish nests one and two backward, bringing them into contact with the baffle. Subsequently, the extrusion shell needs to be grasped and rotated to synchronously rotate the extrusion rod. During rotation, the extrusion rod rotates within the guide cylinder through its threaded grooves. As the guide tube moves downwards under its limit, the second telescopic tube extends, and the compression rod engages with one side of the baffle, thus fixing the baffle. Because the elastic telescopic rod continuously pulls the first and second fish nests, pushing the baffle, and the baffle is restricted by the compression rod and cannot move, it provides support to the rear of the first and second fish nests. This ensures the device maintains a stable posture even under water flow impact or water level fluctuations, effectively preventing the fish nest structure from overturning or shifting. Simultaneously, the magnetic plate will also contact the metal, completing a secondary fixation of the compression rod, further strengthening the overall structure's resistance to disturbance. This ensures the fish nests remain stably suspended for a long time under complex hydrological conditions such as wind, waves, water flow, and frequent water level changes. The magnetic and mechanical dual-insurance mechanism significantly improves locking reliability, avoiding the risk of device loosening due to single-point failure.

[0043] 2. This invention also incorporates a limiting component and an adsorption component. When disassembly is required, the squeezing shell is grasped and rotated in the reverse direction. When the squeezing shell is grasped, it pushes several No. 1 telescopic tubes, squeezing the gas inside into the connecting tube. This causes the elastic telescopic air cylinder to extend rapidly, pushing the squeezing block to slide within the groove. At this time, the cleaning plate also slides on the magnetic plate surface. When the cleaning plate and squeezing block contact the metal plate, the magnetic plate and metal plate separate, and the magnetic attraction is released. Subsequently, the squeezing rod rotates in the reverse direction and rises within the guide cylinder. The baffle, no longer restricted by the squeezing rod, can naturally reset with the rebound force of the elastic telescopic rod. The No. 1 and No. 2 fish nests then loosen their constraint from the limiting ring, facilitating rapid removal. The entire disassembly process requires no tools and does not rely on external power; the synchronous response of magnetic decoupling and mechanical unlocking is achieved solely through structural adaptive deformation. The grasping of the squeezing shell, a necessary step before rotating the connecting tube, reduces the difficulty of using the device, making its operation simple and efficient, perfectly meeting the high-frequency, low-intervention maintenance needs in shallow lake ecological restoration scenarios.

[0044] 3. This invention also incorporates adjustable components and metal plates, enabling rapid assembly of fish nests during ecological restoration projects where time is often tight. This significantly shortens the preparation time for equipment installation, accelerates the overall restoration process, and allows multiple fish nests to be put into use quickly, providing habitats for aquatic life as soon as possible. Furthermore, the fish nests can be stably installed simply by squeezing and rotating the extrusion shell, and disassembly can be completed quickly as well, greatly reducing the complexity of the operation. Construction workers do not need to spend a lot of time and energy on the installation and disassembly of fish nests, thus improving work efficiency and reducing labor costs.

[0062] like Figures 1 to 9 As shown, the present invention relates to an aquatic organism ecological restoration system and its construction method, comprising the following restoration steps:

[0063] S1. Constructing bamboo fish baskets and establishing ecological niches.

[0064] Installing floating fish nest mechanism 1 and sinking fish nest mechanism 3 in the water body provides a growth surface and habitat for aquatic organisms. The surface of the fish nest can be used for algae and other aquatic organisms to attach and grow, forming a small ecosystem. This step is the foundation of the entire restoration process and provides ecological support for subsequent steps.

[0065] S2, Introduction of basic aquatic organisms

[0066] Introducing small aquatic organisms with strong reproductive capabilities, such as freshwater shrimp, allows them to quickly occupy ecological niches and increase biodiversity. Freshwater shrimp can not only provide a food source for large fish, but also reduce pollutants in the water by consuming organic detritus.

[0067] S3, Release fish and insects

[0068] Gradually introduce fish that feed on juvenile shrimp and cladocerans, such as the Yunnan schizothorax, to form the upper structure of the food chain. At the same time, introduce aquatic insects to provide biological food and promote fish growth. The introduction of fish and insects helps to establish a complex food web and enhance the stability of the ecosystem.

[0069] S4. Protect juvenile fish and benthic animals

[0070] Setting up juvenile fish sanctuaries protects them from predators and increases their survival rate. At the same time, it provides shelter for shrimp, crabs, and snails, promoting the reproduction of benthic animals. These benthic animals help reduce sediment resuspension and improve water clarity by feeding on organic matter in the bottom sediment.

[0071] S5, Promotes aquatic plant recovery

[0072] Through the above steps, the water transparency is improved, the light conditions are improved, and the recovery and growth of aquatic plants are promoted. Aquatic plants not only provide habitats for aquatic organisms, but also absorb nutrients from the water, further purifying the water quality.

[0073] In step S1, the floating fish nest mechanism 1 is connected to the bottom-dwelling fish nest mechanism 3 via the connecting rope 2.

[0074] The floating fish nest mechanism 1 includes a frame assembly 11, a floating body assembly 12 connected to the frame assembly 11, four No. 1 fish nests 13 and four No. 2 fish nests 14 connected to the floating body assembly 12, an adjustment assembly 15 connected to the frame assembly 11, a limiting assembly 16 connected to the adjustment assembly 15, several metal plates 17 disposed above the frame assembly 11, an adsorption assembly 18, and a guide cylinder 19. The adsorption assembly 18 is connected to the adjustment assembly 15, and the guide cylinder 19 is located outside the adjustment assembly 15. Through the design of the adjustment assembly 15, metal plates 17, frame assembly 11, and limiting assembly 16, [the mechanism is designed to] [adjust the structure]. Insert the smaller diameter portions of fish nests 13 and 14 into the mounting bracket 111 through the open space above the mounting bracket 111, passing them through the mounting ring 161. As fish nests 13 and 14 gradually extend into the bracket, they gradually come into contact with the inner wall of the limiting ring 119. At this point, continue pushing fish nests 13 and 14 until they completely pass through the mounting plate 112 and no longer contact the baffle 163. The baffle 163 then naturally returns to its original position under gravity, while the elastic telescopic rod 117 pulls the limiting ring 169. Fish nests 13 and 14 move backward and contact baffle 163. Then, the extrusion shell 156 is grasped and rotated to synchronously rotate the extrusion rod 158. As the extrusion rod 158 rotates, it passes through the threaded groove 159 on its surface within the guide cylinder 19 and moves downward under the limit of the guide cylinder 19. At this time, the second telescopic tube 157 extends, and the extrusion rod 158 engages with one side of the baffle 163, completing the fixation of the baffle 163. Because the elastic telescopic rod 117 continuously pulls fish nests 13 and 14, pushing the baffle 163, the baffle 163 is subjected to... The compression rod 158 restricts the movement of the fish nests, thus supporting the rear of fish nests 13 and 14. This ensures the device remains stable under water flow impact or water level fluctuations, effectively preventing the fish nest structure from overturning or shifting. At the same time, the magnetic plate 183 will also come into contact with the metal, completing the secondary fixation of the compression rod 158, further strengthening the overall structure's resistance to disturbance. This ensures the fish nests remain stably suspended for a long time under complex hydrological conditions such as wind, waves, water flow, and frequent changes in water level. The magnetic and mechanical dual insurance mechanism significantly improves the locking reliability and avoids the risk of device loosening due to single-point failure.

[0075] In an embodiment of the present invention, the upper part of the frame assembly 11 is fixedly connected to the lower part of the float assembly 12, and the lower part of the frame assembly 11 is engaged with the outer walls of the four No. 1 fish nests 13 and the four No. 2 fish nests 14. Eight limiting components 16 are all fixedly connected to the lower part of the frame assembly 11, and one side of each of the eight frame assemblies 11 is engaged with one side of each of the four No. 1 fish nests 13 and the four No. 2 fish nests 14. There are eight adjusting components 15, all of which are fixedly connected to the frame assembly 11. Each of the eight adjusting components 15 is engaged with one of the eight limiting components 16, and the outer walls of each of the eight limiting components 16 are connected to eight guide cylinders 19. The adjusting components 15 are connected to the adsorption assembly 12. The components are connected in series 8. One side of the adsorption component 18 is adsorbed onto the outside of the metal plate 17. There are sixteen metal plates 17. The bottom of the float component 12 is fixedly connected to the bottom-dwelling fish nest mechanism 3 via the connecting rope 2. The frame component 11 includes a mounting bracket 111. Eight mounting plates 112 are fixedly connected to the outside of the mounting bracket 111. A limiting groove 113 is opened below the mounting plate 112. A limiting block 114 is slidably connected in the limiting groove 113. A connecting rod 115 is fixedly connected below the limiting block 114. A connecting block 116 is fixedly connected to the outside of the connecting rod 115. The connecting rod 115 is fixedly connected to one end of the elastic telescopic rod 117 through the connecting block 116. The top of the mounting plate 112 is connected to the bottom of the float component 12 via the connecting rope 2. The float assembly 12 is fixedly connected. Through the design of the limiting assembly 16 and the adsorption assembly 18, when disassembly is required, the squeezing shell 156 is grasped and rotated in the reverse direction. When the squeezing shell 156 is grasped, it pushes several telescopic tubes 155 to squeeze the internal gas into the connecting tube 153, causing the elastic telescopic air cylinder 181 to extend rapidly. This allows the elastic telescopic air cylinder 181 to push the squeezing block 184 to slide within the slide groove 186. At this time, the cleaning plate 185 also slides on the surface of the magnetic plate 183. When the cleaning plate 185 and the squeezing block 184 contact the metal plate 17, the magnetic plate 183 and the metal plate 17 are separated, and the magnetic attraction is released. Subsequently... The reverse rotation of the squeezing rod 158 causes it to rise within the guide cylinder 19. The baffle 163, no longer constrained by the squeezing rod 158, can naturally reset itself using the rebound force of the elastic telescopic rod 117. Consequently, fish nests 13 and 14 are released from the constraint of the limiting ring 119, facilitating rapid removal. The entire disassembly process requires no tools and does not rely on external power; the synchronous response of magnetic decoupling and mechanical unlocking is achieved solely through structural adaptive deformation. Furthermore, the necessary steps before rotating the connecting pipe 153 are eliminated when gripping the squeezing shell 156, thus reducing the difficulty of using the device. This makes the device simple and efficient to operate, perfectly meeting the high-frequency, low-intervention maintenance needs in shallow lake ecological restoration scenarios.

[0076] In an embodiment of the present invention, a positioning plate 118 is fixedly connected to the other end of the elastic telescopic rod 117. The upper part of the positioning plate 118 is fixedly connected to the lower part of the mounting plate 112. A limiting ring 119 is fixedly connected to the bottom end of the connecting rod 115. The limiting ring 119 is snapped onto the outside of the first fish nest 13 or the second fish nest 14. The float assembly 12 includes a mounting block 121. Mounting rods 122 are fixedly connected around the mounting block 121. The mounting rods 122 are fixedly connected to the connector 126 through a connecting ring 123. A float ball 125 is threaded onto the connector 126. Several fasteners 124 are fixedly connected to the outside of the mounting rods 122. The lower part of the fasteners 124 is connected to the upper part of the mounting plate 112. The mounting block 121 is fixedly connected to the connecting rope 2 at the bottom. By designing the adjustment component 15 and the metal plate 17, the fish nests can be quickly assembled, which can significantly shorten the preparation time for the installation equipment and speed up the progress of the entire restoration project. The rapid assembly allows multiple fish nests to be put into use quickly, providing habitats for aquatic organisms as soon as possible. The fish baskets can be stably installed by simply squeezing and rotating the squeezing shell 156, and disassembly can also be completed quickly, greatly reducing the complexity of the operation. Construction personnel do not need to spend a lot of time and energy on the installation and disassembly of the fish nests, which improves work efficiency and reduces labor costs.

[0077] In another embodiment of the present invention, the adjusting component 15 includes a base plate 151, a sleeve 152 fixedly connected to the upper part of the base plate 151, a connecting tube 153 sleeved inside the sleeve 152, the top end of the connecting tube 153 communicating with a connecting tube 154, a plurality of first telescopic tubes 155 fixedly connected to the outside of the connecting tube 154, a plurality of first telescopic tubes 155 located on one side being fixedly connected to the same extrusion shell 156, the outer wall of the connecting tube 153 communicating with the adsorption component 18, the base plate 151 being fixedly connected to the mounting bracket 111, and the bottom end of the connecting tube 153 passing through the sleeve 152 and the second extrusion shell 156. Telescopic tubes 157 are connected. The second telescopic tube 157 is a limiting telescopic tube. The bottom end of the second telescopic tube 157 is fixedly connected to a pressing rod 158. The pressing rod 158 has a threaded groove 159. The guide cylinder 19 is sleeved on the outside of the pressing rod 158 and is snapped into the threaded groove 159. Because an installation rod 122 is provided and a connector 126 is provided on the outside of the installation rod 122, the device can quickly assemble and disassemble the float 125. At the same time, a connecting ring 123 is provided on the outside of the installation rod 122 to avoid obstruction when rotating the pressing shell 156.

[0078] Because a retaining plate 164 is designed on one side of the baffle 163, the three baffles 163 can be restricted together by restricting one of the baffles 163. This ensures that after the squeezing rod 158 restricts one of the baffles 163, the baffle 163 can restrict the first fish nest 13 and the second fish nest 14 through the push block 165, which reduces the difficulty of assembling the device.

[0079] In another embodiment of the present invention, the limiting component 16 includes a mounting ring 161, three rotating rods 162 are fixedly connected inside the mounting ring 161, and baffles 163 are sleeved on the outside of each of the three rotating rods 162. The three baffles 163 are staggered. A push block 165 is fixedly connected to one side of the baffle 163, and a clamping plate 164 is fixedly connected to the outside of the baffle 163. The three clamping plates 164 overlap each other. The baffle 163 overlaps with either the first fish nest 13 or the second fish nest 14 through the push block 165. The upper part of the mounting plate 112 is fixedly connected to the mounting frame 111 through a positioning post. The guide cylinder 19 is fixedly connected to the mounting ring 161. The squeezing rod 158 is clamped to the outside of one of the baffles 163. The adsorption component 18 includes an elastic telescopic air cylinder 181, and a... A retainer 182 is fixedly connected to a magnetic plate 183 at one end. A compression block 184 is fixedly connected to one end of an elastic telescopic air cylinder 181. The compression block 184 is fixedly connected to two cleaning plates 185, which overlap the two sides of the magnetic plate 183. A groove 186 is provided on one side of the magnetic plate 183, and the compression block 184 is slidably connected in the groove 186. The other end of the elastic telescopic air cylinder 181 is connected to a connecting pipe 154. The same side of the magnetic plate 183 is attracted to one of the metal plates 17. By limiting the device with a limiting ring 119, the device can be installed and put into use on all fish nests whose one end size is larger than the inner diameter of the limiting ring 119. This installation method can flexibly cope with various situations and improve the applicability of the device.

[0080] Working Principle: This embodiment provides an aquatic organism ecological restoration system and its construction method. In use, multiple No. 1 fish nests 13 and No. 2 fish nests 14 are installed. The smaller diameter portions of the No. 1 fish nests 13 and No. 2 fish nests 14 are inserted into the mounting frame 111 through the open space above the mounting frame 111 and pass through the mounting ring 161. As the No. 1 fish nests 13 and No. 2 fish nests 14 gradually extend, they gradually come into contact with the inner wall of the limiting ring 119. At this point, the No. 1 fish nests 13 and No. 2 fish nests 14 are continuously pushed until they completely pass through the mounting plate 112 and no longer contact the baffle 163. At this point, the baffle 163 naturally returns to its original position under gravity, while the elastic telescopic rod 117... The limiting ring 119 and the first and second fish nests 13 and 14 will be pulled backward and brought into contact with the baffle 163. Then, the extrusion shell 156 needs to be grasped and rotated to synchronously drive the extrusion rod 158 to rotate. When the extrusion rod 158 rotates, it will rotate in the guide cylinder 19 through the threaded groove 159 on its surface and move downward under the limit of the guide cylinder 19. At this time, the second telescopic tube 157 extends, and the extrusion rod 158 is engaged with one side of the baffle 163, completing the fixation of the baffle 163. Since the elastic telescopic rod 117 continuously pulls the first and second fish nests 13 and pushes the baffle 163, the baffle 163 is restricted by the extrusion rod 158 and cannot move, thus providing support for the rear side of the first and second fish nests 13 and 14.

[0081] When disassembly is required, grasp the extrusion shell 156 and rotate it in the opposite direction. When the extrusion shell 156 is grasped, it will push several No. 1 telescopic tubes 155 to squeeze the gas inside into the connecting tube 153, causing the elastic telescopic air cylinder 181 to extend quickly. This allows the elastic telescopic air cylinder 181 to push the extrusion block 184 to slide in the slide groove 186. At this time, the cleaning plate 185 will also slide on the surface of the magnetic plate 183. When the cleaning plate 185 and the extrusion block 184 come into contact with the metal plate 17, the magnetic plate 183 and the metal plate 17 will be separated, and the magnetic attraction will be released. Then, rotate the extrusion rod 158 in the opposite direction to rise in the guide cylinder 19. The baffle 163, no longer restricted by the extrusion rod 158, can naturally reset with the rebound force of the elastic telescopic rod 117. The No. 1 fish nest 13 and the No. 2 fish nest 14 will then be released from the constraint of the limiting ring 119, making it easy to quickly remove them.

[0082] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
