Description

Technical Field

[0001] The present invention relates to the technical field of water ecological restoration, and particularly to a water ecological restoration device and a water ecological restoration method thereof. Background Technique

[0002] Ecological restoration is a comprehensive method for restoring polluted environments under the guidance of ecological principles, based on bioremediation, combined with various physical, chemical, and engineering technical measures, and optimized to achieve the best effect and the lowest cost. The successful implementation of ecological restoration requires the participation of multiple disciplines such as ecology, physics, chemistry, botany, microbiology, molecular biology, cultivation, and environmental engineering;

[0003] Ecological restoration is divided into terrestrial ecological restoration and water ecological restoration. Terrestrial ecological restoration refers to the restoration of the terrestrial environment and soil, increasing terrestrial vegetation and soil nutrient factors. Water ecological restoration is to neutralize and purify harmful substances in water bodies and clean pollutants in water, such as salvaging substances such as plastics, garbage, and feces in water. Water ecological restoration includes means such as physical restoration, chemical restoration, bioremediation, and engineering restoration. Among them, bioremediation uses the ecological floating island technology. An ecological floating island, also known as an artificial floating bed, ecological floating bed, etc., is a type of artificial floating island. For eutrophic water quality, using the principles of ecological engineering, it degrades COD, nitrogen, and phosphorus in water. It takes aquatic plants as the main body, applies the principles of soilless cultivation technology, uses high-molecular materials, etc. as carriers and substrates, and applies the symbiotic relationship between species, making full use of the ecological niche in the water body space and the nutrient ecological niche, thereby establishing an efficient artificial ecosystem to reduce the pollution load in the water body. An ecological floating island usually consists of multiple modules spliced together.

[0004] However, when carrying out water ecological restoration by means of ecological floating islands, it is necessary to manually dock the ecological floating islands one by one, which is rather cumbersome and time-consuming, resulting in a slow construction efficiency of the ecological floating island erection, and it is rather inconvenient to construct on the water surface when increasing the number of ecological floating islands subsequently; Therefore, it does not meet the existing requirements, and for this reason, we propose a water ecological restoration device and a water ecological restoration method thereof. Summary of the Invention

[0005] The purpose of the present invention is to provide a water ecological restoration device and a water ecological restoration method thereof to solve the problems mentioned in the above background technique, that is, when carrying out water ecological restoration by means of ecological floating islands, it is necessary to manually dock the ecological floating islands one by one, which is rather cumbersome and time-consuming, resulting in a slow construction efficiency of the ecological floating island erection, and it is rather inconvenient to construct on the water surface when increasing the number of ecological floating islands subsequently.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An aquatic ecological restoration device includes a plurality of buoyancy plates. A through circular hole is provided at the center of the buoyancy plate. Four installation inner grooves are provided inside the buoyancy plate, and the four installation inner grooves are distributed in a circular array around the axis of the circular hole. A waterproof rubber outer sleeve is installed inside the installation inner groove, and a docking control processing chip and two ultrasonic ranging and positioning chips are installed inside the waterproof rubber outer sleeve;

[0008] Four rotationally symmetric rotation positioning docking rods are installed on the upper surface of the buoyancy plate. A fixing groove is provided between every two adjacent installation inner grooves. A positioning hole is provided above the fixing groove. Fixed bearing plates are fixed at the middle positions of the four sides of the buoyancy plate. A laser positioning receiver is fixed on the upper surface of one end of the fixed bearing plate, and a laser positioning laser probe is installed directly above the laser positioning receiver.

[0009] Preferably, the rotation positioning docking rod includes a docking motor. The docking motor is installed inside the fixing groove and fixed to the buoyancy plate. A rotation support shaft is fixed to the output shaft end of the docking motor. The bottom end of the rotation support shaft is rotatably inserted inside the positioning hole, and a rotation mounting seat is fixed to the top end of the rotation support shaft. The laser positioning laser probe is fixed to the bottom surface of the end of the docking electric telescopic rod away from the buoyancy plate.

[0010] Preferably, a fixed bearing block is fixed to the movable end of the docking electric telescopic rod. A rotation positioning clamping rod is fixed to one side of the fixed bearing block. The end of the rotation positioning clamping rod connected to the fixed bearing block is bent at a right angle, and the other end of the rotation positioning clamping rod is bent in a U shape.

[0011] Preferably, a positioning contact pressure sensor is embedded on the outer side of the end of the rotation positioning clamping rod bent in a U shape. An anti - detachment plugging block is fixed to the end face of the end of the rotation positioning clamping rod bent in a U shape. A through anti - detachment plugging groove is provided at the bending part of the end of the rotation positioning clamping rod bent in a U shape.

[0012] Preferably, the cross - sectional size of the anti - detachment plugging groove is the same as that of the anti - detachment plugging block, and the anti - detachment plugging block is slidably inserted inside the anti - detachment plugging groove.

[0013] Preferably, four symmetrically distributed solar panels are fixed on the upper surface of the buoyancy plate. A storage battery is built in the buoyancy plate. The storage battery is connected to the docking electric telescopic rod, the positioning contact pressure sensor, the docking motor, the docking control processing chip, and the ultrasonic ranging and positioning chip through wires. A green plant cultivation bearing net is fixed to the bottom of the buoyancy plate. The axis of the green plant cultivation bearing net coincides with the axis of the circular hole. Ventilation holes are provided on the bottom surface and the outer side of the green plant cultivation bearing net.

[0014] Preferably, docking rods are provided on both sides of the fixed bearing plate. The two docking rods are symmetrically positioned and fixed to the side surface of the buoyancy plate.

[0015] Preferably, the docking rod includes a fixed rod. One end of the fixed rod is fixed to the buoyancy plate, and an elastic docking plate is fixed to the other end of the fixed rod. The elastic docking plate is U-shaped and has clamping cylindrical blocks fixed to both ends.

[0016] Preferably, a docking slot is provided inside the elastic docking plate. The clamping cylindrical block is slidably clamped inside the docking slot. The width dimension of the docking slot is the same as the diameter dimension of the clamping cylindrical block. The distance dimension between the two clamping cylindrical blocks at both ends of the same elastic docking plate is smaller than the diameter dimension of the clamping cylindrical block.

[0017] The present invention also provides a water ecological restoration method, which uses the water ecological restoration equipment as described above and includes the following steps:

[0018] S1: First, place the water ecological restoration green plants for soilless cultivation inside the green plant cultivation bearing net.

[0019] S2: Then, place the green plant cultivation bearing net and the buoyancy plate cultivated with the water ecological restoration green plants for soilless cultivation on the water surface.

[0020] S3: Push the buoyancy plate to float and move on the water surface and approach each other.

[0021] S4: The ultrasonic ranging and positioning chip inside the buoyancy plate monitors the distance between the two buoyancy plates. After the two buoyancy plates approach a certain distance, the docking motors on the mutually facing sides of the two buoyancy plates are powered on and started.

[0022] S5: After the docking motor is started, it drives the rotating support shaft, the rotating mounting seat, and the docking electric telescopic rod to perform circular motion around the axis of the rotating support shaft.

[0023] S6: The docking electric telescopic rod drives the rotating positioning clamping rod to rotate through the fixed bearing block. At this time, the rotating directions of the rotating positioning clamping rods on the two buoyancy plates are completely opposite.

[0024] S7: Until the positioning contact pressure sensors on the outer sides of the two rotating rotating positioning clamping rods contact the docking electric telescopic rod. At this time, the positioning contact pressure sensor detects the pressure, and at the same time, the movable end of the docking electric telescopic rod contracts.

[0025] S8: The docking electric telescopic rod drives the rotating positioning clamping rod to move towards the rotating mounting seat. At the same time, the two rotating positioning clamping rods fit against the docking electric telescopic rod and move along the axis of the docking electric telescopic rod. When the ends of the two rotating positioning clamping rods are misaligned with each other, at this time, the rotating positioning clamping rod enters the inside of the other rotating positioning clamping rod because the docking electric telescopic rod rotates around the axis of the rotating support shaft;

[0026] S9: The two rotating positioning clamping rods continue to move until the anti - detachment plug - in blocks at the ends of the two rotating positioning clamping rods are clamped in the corresponding anti - detachment plug - in slots. At this time, the two buoyancy plates are initially docked through the two rotating positioning clamping rods;

[0027] S10: At this time, the docking motor continues to drive the rotation of the rotating support shaft, the rotating mounting seat, and the docking electric telescopic rod until the laser positioning laser probe on the bottom surface of the end of the docking electric telescopic rod moves directly above the laser positioning receiver, and the laser emitted from the anti - detachment plug - in slot is received by the positioning contact pressure sensor, indicating that the docking electric telescopic rod is perpendicular to the side surface of the buoyancy plate;

[0028] S11: The docking motor is powered off and stops running, and the docking electric telescopic rod is powered on and starts to continue pulling the rotating positioning clamping rod, causing the rotating positioning clamping rod to move towards the buoyancy plate. At this time, the two buoyancy plates move closer to each other;

[0029] S12: Until the rotating positioning clamping rod reaches the limit stroke position of the docking electric telescopic rod. At this time, the two buoyancy plates are clamped and fixed to the two docking rods fixed on the side surfaces facing each other. The assembly and splicing of the buoyancy plates are completed through the two docking rods and the two rotating positioning clamping rods;

[0030] S13: Repeat the above assembly process of the buoyancy plates to splice and assemble all the buoyancy plates to complete the construction of the ecological floating island. Use the hydroponic green plants for water ecological restoration planted in the ecological floating island to carry out biological restoration of the water ecological environment.

[0031] 1. In the present invention, the green plants for water ecological restoration in soilless cultivation are planted in the green plant cultivation carrier net, and the buoyancy board after planting is placed on the water surface. Two buoyancy boards both planted with green plants for water ecological restoration in soilless cultivation are pushed to approach each other. During the process of the two buoyancy boards approaching each other, the docking motor is powered on and starts to drive the fixed bearing block and the rotating positioning clamping rod to rotate through the rotating support shaft, the rotating mounting seat, and the docking electric telescopic rod. Moreover, the rotating directions of the rotating positioning clamping rods on the two buoyancy boards are completely opposite, so that the two rotating positioning clamping rods contact the extended ends of the two docking electric telescopic rods. After the rotating positioning clamping rod contacts the docking electric telescopic rod, the movable end of the docking electric telescopic rod retracts, causing the two rotating positioning clamping rods to approach each other. And when the two rotating positioning clamping rods cross each other, the docking motor makes the fixed bearing block and the rotating positioning clamping rod continue to rotate through the rotating support shaft, the rotating mounting seat, and the docking electric telescopic rod, so that the ends of the two rotating positioning clamping rods are clamped with each other, and the anti - detachment plug - in block at the end of the rotating positioning clamping rod is slidably inserted into the corresponding anti - detachment plug - in groove. The adjacent buoyancy boards are spliced and assembled through the two rotating positioning clamping rods, directly assembling the ecological floating island on the water surface, reducing the operation difficulty of the ecological floating island, shortening the assembly time, reducing the working intensity, liberating the hands of the staff, saving the number of labor and cost, and facilitating the subsequent increase of the number of buoyancy boards in the ecological floating island and expanding the area of the ecological floating island.

[0032] 2. After multiple buoyancy boards are spliced into an ecological floating island through the rotating positioning clamping rods, if you want to continue to increase the number of buoyancy boards in the ecological floating island, you only need to place the added buoyancy board on the water surface and push the buoyancy board so that it floats towards the edge of the ecological floating island. After the buoyancy board approaches the ecological floating island, the rotating positioning clamping rod on the side of the buoyancy board at the edge of the ecological floating island is used. Driven by the docking motor, the rotating support shaft, the rotating mounting seat, the docking electric telescopic rod, and the fixed bearing block, it rotates and docks with the buoyancy board approaching the ecological floating island, which can expand the area of the ecological floating island at any time, with relatively low operation difficulty, short time consumption, and high assembly efficiency.

[0033] 3. After the two rotating positioning clamping rods complete the splicing and assembly of the adjacent buoyancy boards, the clamping cylindrical block at the end of the elastic docking board on the side of one buoyancy board is clamped into the docking slot inside the elastic docking board on the side of the other buoyancy board, so that the two aligned elastic docking boards are clamped and fixed to each other through the clamping cylindrical block at the end. Without external intervention, the two elastic docking boards cannot be separated. The connection between the two buoyancy boards is strengthened through the fixed rod and the elastic docking board, ensuring the stability and connection strength of the overall structure of the ecological floating island assembled by multiple buoyancy boards.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] The ultrasonic ranging and positioning chip (model CS100A), docking motor (model 60KTYZ), positioning contact pressure sensor (model GZP160), and docking electric telescopic rod (model GR20) mentioned in the present invention can all be obtained by purchasing from the market or customizing privately.

[0045] As Figures 1 to 3As shown in the figure, a water ecological restoration device is provided. A through circular hole is provided at the center of the buoyancy plate 1. Four installation inner grooves 9 are provided inside the buoyancy plate 1. The four installation inner grooves 9 are distributed in a circular array around the axis of the circular hole. A waterproof rubber outer sleeve 10 is installed inside the installation inner groove 9. Inside the waterproof rubber outer sleeve 10, a docking control processing chip 11 and two ultrasonic ranging and positioning chips 12 are installed. The ultrasonic ranging and positioning chip 12 monitors the distance between two adjacent buoyancy plates 1, which is convenient for subsequent assembly of two adjacent buoyancy plates 1. The waterproof rubber outer sleeve 10 surrounds and protects the docking control processing chip 11 and the ultrasonic ranging and positioning chip 12, preventing the docking control processing chip 11 and the ultrasonic ranging and positioning chip 12 from being damaged or malfunctioning due to contact with water.

[0046] Four symmetrically distributed solar panels 2 are fixed on the upper surface of the buoyancy plate 1. A storage battery is built into the buoyancy plate 1. The storage battery is connected to the docking electric telescopic rod 403, the positioning contact pressure sensor 407, the docking motor 409, the docking control processing chip 11, and the ultrasonic ranging and positioning chip 12 through wires. A green plant cultivation bearing net 5 is fixed at the bottom of the buoyancy plate 1. The axis of the green plant cultivation bearing net 5 coincides with the axis of the circular hole. Ventilation holes are provided on the bottom surface and the outside of the green plant cultivation bearing net 5. The solar panels 2 convert solar energy into electricity for powering the docking electric telescopic rod 403, the positioning contact pressure sensor 407, the docking motor 409, the docking control processing chip 11, and the ultrasonic ranging and positioning chip 12. The green plant cultivation bearing net 5 is used to bear the water ecological restoration green plants for soilless cultivation, ensuring that the water ecological restoration green plants for soilless cultivation do not fall from the middle of the buoyancy plate 1 and guaranteeing the stability and normal growth of the water ecological restoration green plants for soilless cultivation.

[0047] Four rotationally symmetric rotation positioning docking rods 4 are installed on the upper surface of the buoyancy plate 1. A fixed groove 13 is provided between every two adjacent installation inner grooves 9. A positioning hole 14 is provided above the fixed groove 13. Fixed bearing plates 6 are fixed at the middle positions of the four side surfaces of the buoyancy plate 1. A laser positioning receiver 7 is fixed on the upper surface of one end of the fixed bearing plate 6. A laser positioning laser probe 8 is installed directly above the laser positioning receiver 7.

[0048] As Figures 2 to 6As shown in the figure, the rotary positioning docking rod 4 includes a docking motor 409. The docking motor 409 is installed inside the fixed slot 13 and fixed to the buoyancy plate 1. A rotary support shaft 401 is fixed to the output shaft end of the docking motor 409. The bottom end of the rotary support shaft 401 is rotatably inserted inside the positioning hole 14. And a rotary mounting seat 402 is fixed to the top end of the rotary support shaft 401. The laser positioning laser probe 8 is fixed to the bottom surface of the end of the docking electric telescopic rod 403 away from the buoyancy plate 1. A fixed bearing block 404 is fixed to the movable end of the docking electric telescopic rod 403. A rotary positioning clamping rod 405 is fixed to one side of the fixed bearing block 404. The end of the rotary positioning clamping rod 405 connected to the fixed bearing block 404 is bent at a right angle. The other end of the rotary positioning clamping rod 405 is bent in a U shape. The docking motor 409 is used to drive the rotary support shaft 401 and the rotary mounting seat 402 to rotate, so that the rotary mounting seat 402 drives the docking electric telescopic rod 403 to rotate simultaneously, changing the positions of the fixed bearing block 404 and the rotary positioning clamping rod 405 at the end of the docking electric telescopic rod 403, and realizing the mutual docking of the two rotary positioning clamping rods 405 above the adjacent sides of the two buoyancy plates 1.

[0049] A positioning contact pressure sensor 407 is embedded on the outer side of the end of the rotary positioning clamping rod 405 bent in a U shape. An anti - detachment plugging block 406 is fixed to the end face of the end of the rotary positioning clamping rod 405 bent in a U shape. A through anti - detachment plugging groove 408 is provided at the bending part of the end of the rotary positioning clamping rod 405 bent in a U shape. The cross - sectional size of the anti - detachment plugging groove 408 is the same as that of the anti - detachment plugging block 406. The anti - detachment plugging block 406 is slidably inserted inside the anti - detachment plugging groove 408. The positioning contact pressure sensor 407 on the outer side of the end of the rotary positioning clamping rod 405 is used to sense whether the two rotary positioning clamping rods 405 on the mutually facing sides of the two buoyancy plates 1 are in contact during rotation. If the two rotary positioning clamping rods 405 are in contact, the position of the rotary positioning clamping rod 405 is adjusted through the docking electric telescopic rod 403, so that the ends of the two rotary positioning clamping rods 405 bent in a U shape are mutually clamped, and the anti - detachment plugging blocks 406 at the ends of the two rotary positioning clamping rods 405 are respectively inserted into the two anti - detachment plugging grooves 408 to fix the docking of the two rotary positioning clamping rods 405. The docking of the two buoyancy plates 1 is realized through the two rotary positioning clamping rods 405.

[0050] As Figure 2 、 Figure 7 and Figure 8As shown in the figure, docking rods 3 are provided on both sides of the fixed bearing plate 6. The two docking rods 3 are symmetrically positioned and fixed to the side surface of the buoyancy plate 1. The docking rod 3 includes a fixed rod 301. One end of the fixed rod 301 is fixed to the buoyancy plate 1, and an elastic docking plate 302 is fixed to the other end of the fixed rod 301. The elastic docking plate 302 is U-shaped and bent, and clamping cylindrical blocks 303 are fixed to both ends. A docking slot 304 is provided inside the elastic docking plate 302. The clamping cylindrical blocks 303 are slidably clamped inside the docking slot 304. The width dimension of the docking slot 304 is the same as the diameter dimension of the clamping cylindrical blocks 303. The spacing dimension between the two clamping cylindrical blocks 303 at both ends of the same elastic docking plate 302 is smaller than the diameter dimension of the clamping cylindrical blocks 303. By clamping the docking rods 3 on the mutually facing sides of two adjacent buoyancy plates 1, the clamping cylindrical block 303 at the end of one elastic docking plate 302 is clamped in the docking slot 304 inside the other elastic docking plate 302, connecting and fixing the two docking rods 3, thereby connecting and fixing the buoyancy plates 1 docked by the two rotary positioning docking rods 4, ensuring that the two spliced buoyancy plates 1 will not easily separate from each other.

[0051] Working principle: First, the green plants for water ecological restoration in soilless cultivation are cultivated in the green plant cultivation bearing net 5 at the bottom of the buoyancy plate 1. After the green plants for water ecological restoration in soilless cultivation are planted inside all the buoyancy plates 1, the buoyancy plates 1 are placed on the water surface to float, and the floating buoyancy plates 1 are pushed on the water surface to make the floating buoyancy plates 1 approach each other. During the process of the buoyancy plates 1 approaching each other, the ultrasonic ranging and positioning chip 12 inside the buoyancy plate 1 always detects the distance between two adjacent buoyancy plates 1. At the same time, the docking electric telescopic rod 403 is powered on and starts, and its movable end extends, so that the fixed bearing block 404 and the rotary positioning clamping rod 405 reach the position farthest from the buoyancy plate 1. When the distance between the two buoyancy plates 1 enables the two rotary positioning clamping rods 405 to contact each other, the docking motor 409 inside the buoyancy plate 1 is powered on and starts, and drives the rotary support shaft 401, the rotary mounting seat 402 and the docking electric telescopic rod 403 to perform a circular motion around the axis of the rotary support shaft 401;

[0052] The rotating positioning clamping rod 405 and the fixed bearing block 404 make circular motions around the axis of the rotating support shaft 401 along with the docking electric telescopic rod 403. At this time, the rotating directions of the docking electric telescopic rods 403 above the two buoyancy plates 1 are opposite, causing the two rotating positioning clamping rods 405 to make circular motions in different directions. During the rotation, the positioning contact pressure sensor 407 on the side of the rotating positioning clamping rod 405 contacts the side of the extended end of the docking electric telescopic rod 403. After the two rotating positioning clamping rods 405 respectively contact the two docking electric telescopic rods 403, the docking motor 409 temporarily stops running. Then the docking electric telescopic rod 403 is powered on and starts. The movable end of the docking electric telescopic rod 403 retracts and drives the rotating positioning clamping rod 405 to approach the original buoyancy plate 1 through the fixed bearing block 404. At this time, the rotating positioning clamping rod 405 slides along the outer surface of the docking electric telescopic rod 403 of the other buoyancy plate 1 until the rotating positioning clamping rod 405 separates from the docking electric telescopic rod 403 in contact. At this time, the ends of the two rotating positioning clamping rods 405 are mutually misaligned;

[0053] At this time, the docking motor 409 is powered on and starts again, and continues to drive the rotating positioning clamping rod 405 to rotate through the rotating support shaft 401, the rotating mounting seat 402, the docking electric telescopic rod 403 and the fixed bearing block 404, so that the U-shaped bent ends of the two rotating positioning clamping rods 405 are mutually clamped inside the ends. Along with the continuous driving of the rotating positioning clamping rod 405 by the docking electric telescopic rod 403, until the anti-disengagement plugging block 406 at the end of the rotating positioning clamping rod 405 slides and plugs inside the corresponding anti-disengagement plugging groove 408, so that the two rotating positioning clamping rods 405 are mutually clamped and fixed. At this time, the docking motor 409 continues to drive the rotating support shaft 401, the rotating mounting seat 402, and the docking electric telescopic rod 403 to rotate until the laser positioning laser probe 8 at the bottom surface of the end of the docking electric telescopic rod 403 moves directly above the laser positioning receiver 7, and the laser emitted by the anti-disengagement plugging groove 408 is received by the positioning contact pressure sensor 407, indicating that the docking electric telescopic rod 403 is perpendicular to the side of the buoyancy plate 1;

[0054] After the anti - detachment docking groove 408 is aligned with the positioning contact pressure sensor 407, the docking motor 409 is powered off and stops operating. The docking electric telescopic rod 403 is powered on and starts to continue pulling the rotating positioning clamping rod 405, causing the rotating positioning clamping rod 405 to move towards the buoyancy plate 1. At this time, the two buoyancy plates 1 approach each other. During the continuous approach of the two buoyancy plates 1, the two elastic docking plates 302 are aligned, and the clamping cylindrical blocks 303 at the ends of the elastic docking plates 302 move into the docking slots 304 inside the elastic docking plates 302. The clamping cylindrical block 303 at the end of one elastic docking plate 302 squeezes the two clamping cylindrical blocks 303 at the end of the other elastic docking plate 302, causing the two ends of the elastic docking plate 302 to expand, so that the clamping cylindrical block 303 at the end of one elastic docking plate 302 enters the docking slot 304 inside the other elastic docking plate 302, making the two elastic docking plates 302 clamped and fixed to each other until the end of the docking electric telescopic rod 403 is completely retracted. At this time, the two adjacent buoyancy plates 1 are spliced and assembled through the two rotating positioning clamping rods 405, the two elastic docking plates 302 and the clamping cylindrical blocks 303 at the ends of the elastic docking plates 302. Repeating the above operations to assemble all the buoyancy plates 1, directly assembling the ecological floating island on the water surface, reducing the operation difficulty of the ecological floating island, shortening the assembly time, reducing the work intensity, liberating the hands of the staff, saving the number of workers and costs, and facilitating the subsequent increase in the number of buoyancy plates in the ecological floating island and expanding the area of the ecological floating island.

[0055] The present invention also provides a water ecological restoration method, which uses the above - mentioned water ecological restoration equipment and includes the following steps:

[0056] S1: First, put the water ecological restoration green plants for soilless cultivation into the green plant cultivation carrier net 5;

[0057] S2: Then place the green plant cultivation carrier net 5 and the buoyancy plate 1 that have cultivated the water ecological restoration green plants for soilless cultivation on the water surface;

[0058] S3: Push the buoyancy plate 1 to float and move on the water surface and approach each other;

[0059] S4: The ultrasonic ranging and positioning chip 12 inside the buoyancy plate 1 monitors the distance between the two buoyancy plates 1. After the two buoyancy plates 1 approach a certain distance, the docking motor 409 on the mutually facing sides of the two buoyancy plates 1 is powered on and starts;

[0060] S5: After the docking motor 409 starts, it drives the rotating support shaft 401, the rotating mounting seat 402 and the docking electric telescopic rod 403 to make a circular motion around the axis of the rotating support shaft 401;

[0061] S6: The docking electric telescopic rod 403 drives the rotary positioning clamping rod 405 to rotate through the fixed bearing block 404. At this time, the rotary directions of the rotary positioning clamping rods 405 on the two buoyancy plates 1 are completely opposite;

[0062] S7: Until the positioning contact pressure sensors 407 on the outer sides of the two rotating rotary positioning clamping rods 405 contact the docking electric telescopic rod 403. At this time, the positioning contact pressure sensors 407 detect pressure, and at the same time, the movable end of the docking electric telescopic rod 403 contracts;

[0063] S8: The docking electric telescopic rod 403 drives the rotary positioning clamping rod 405 to move towards the rotary mounting seat 402. At the same time, the two rotary positioning clamping rods 405 fit against the docking electric telescopic rod 403 and move along the axis of the docking electric telescopic rod 403. Until the ends of the two rotary positioning clamping rods 405 are misaligned with each other, at this time, the rotary positioning clamping rod 405 rotates around the axis of the rotary support shaft 401 due to the docking electric telescopic rod 403 and enters the inner side of another rotary positioning clamping rod 405;
