However, with current technology, the plants in the planting boxes are always above the water surface when using in-situ treatment to improve water quality. Strong winds can damage these plants, hindering the improvement of the water environment. Summary of the Invention

When the rotating shaft rotates, the pusher plate rotates upward under the action of the pushing water resistance to change the tilt angle. When the rotation speed of the rotating shaft is less than a first threshold, the through hole is closed by the pusher plate. When the rotation speed of the rotating shaft is greater than the first threshold and less than a second threshold, the pusher plate pushes water downward. When the rotation speed of the rotating shaft is greater than the second threshold, the pusher plate pushes water upward.

[0006] Furthermore, the disc is rotatably connected to a first connecting rod, which is fixedly connected to the push plate.

[0007] Furthermore, the rotating shaft is provided with a protective box, the disc is connected to the outer periphery of the protective box, the side wall of the protective box is provided with a first through hole, the first through hole is aligned with the first connecting rod, the protective box is provided with a ratchet, a pawl and a lever, the spring includes a first torsion spring and a second torsion spring, the elastic coefficient of the first spring is less than the elastic coefficient of the second spring, the first torsion spring connects the ratchet and the push plate, the second torsion spring connects the ratchet and the protective box, the lever is slidably connected to the protective box and is provided with the pawl, the protective box is provided with a spring plate that pushes the pawl to engage with the ratchet, when the push plate covers the through hole, it pushes the lever to disengage the ratchet from the pawl.

[0008] Furthermore, the lever is U-shaped, with one end being a telescopic rod. The telescopic rod includes a sleeve, a pressure spring, and a movable column. The movable column is slidably connected to the sleeve. The pressure spring pushes the telescopic rod to extend. The movable column is provided with an upper V-shaped groove, a lower V-shaped groove, and a transition groove. The top of the upper V-shaped groove and the top of the lower V-shaped groove are connected through the transition groove to form a sliding rail. The sleeve is provided with an elastic strip that slides along the sliding rail. The upper V-shaped groove and the lower V-shaped groove are located on both sides of the elastic strip.

[0012] Furthermore, the spiral spring is housed within the protective casing.

[0013] The beneficial effects of this invention are as follows:

[0014] This system allows plants to be submerged in water during strong winds and then raised to the surface for photosynthesis once the wind subsides. In calm conditions, it maintains a relatively constant water level, preventing damage from strong winds and avoiding prolonged submersion due to lack of sunlight and oxygen. When alternating strong and weak winds occur, the system keeps the plants submerged until the strong winds completely cease or the wind intensity decreases significantly over a given period. This balanced approach helps prevent damage from strong winds or prolonged submersion. Attached Figure Description

Detailed Implementation

[0023] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0024] Example 1

[0025] See Figures 1-2 A device for in-situ treatment to improve water quality includes a floating body, a planting box, a water storage tank, an air cup, an inlet and outlet pipe, and a pusher plate. The floating body floats on the water surface and has a channel within it. The planting box is located within the channel and contains planting substrate and plants for water purification. Vertical rods are arranged around the channel, and a limiting crossbar is provided at the bottom of the vertical rods to support the bottom of the planting box. The planting box is made of buoyancy material and includes the water storage tank. An air supply pipe is connected to the top of the water storage tank. The inlet and outlet pipes are inverted U-shaped, with one end inserted into the water storage tank and the other end always submerged below the water surface. A point on the submerged end of the inlet and outlet pipe is connected to... A bypass pipe is connected to a rotating shaft. The upper end of the rotating shaft is always above the water surface and is connected to a wind cup. The lower end of the rotating shaft is provided with a disc. The disc has a through hole, and the lower end of the through hole is hinged to the lower end of the pusher plate. The disc is provided with a spring. The spring drives the pusher plate to move towards the direction that covers the through hole. After the pusher plate covers the through hole, it is inclined to the horizontal plane and its upper part is higher than the top surface of the disc. When the rotating shaft rotates, the pusher plate rotates upward under the action of the pushing water resistance to change the tilt angle. When the rotation speed of the rotating shaft is less than a first threshold, the through hole is closed by the pusher plate. When the rotation speed of the rotating shaft is greater than the first threshold and less than a second threshold, the pusher plate pushes water downward. When the rotation speed of the rotating shaft is greater than the second threshold, the pusher plate pushes water upward.

[0026] A floating body 1 floats on the water surface. A channel 7 inside the floating body 1 can hold a planting box 2, which contains a planting substrate 8 and plant materials 9. The plant materials 9 are used to purify impurities in the water. Vertical rods 10 are installed around the channel 7 to prevent the planting box 2 from detaching from the floating body 1. A limiting crossbar is installed at the bottom of the vertical rods 10 to restrict the downward movement of the planting box 2 and prevent it from sinking to the bottom. The planting box 2 itself is also made of buoyancy material. A water storage tank 3 is installed in the planting box 2. An air supply pipe 13 is connected to the top of the water storage tank 3, allowing outside air to enter the water storage tank 3. The upper end of the air supply pipe 13 is always above the water surface. The inlet and outlet pipes 5 are inverted U-shaped, with one end inserted into the water storage tank 3 and the other end below the water surface outside the tank 3. Preferably, the liquid level in the water storage tank 3 is at the same level as the ambient water level, or the height difference between the two is less than 1-5 cm. When the inlet and outlet pipes 5 are full of water, the water storage tank 3 is connected to the ambient water. When the push plate 6 rotates, water can be pumped into the water storage tank 3 or water can be discharged from the water storage tank 3. When the inlet and outlet pipes 5 are full of air, the push plate 6 needs to be rotated to fill the inlet and outlet pipes 5 with water before water can be pumped into or discharged from the water storage tank 3.

[0027] A bypass pipe 14 is connected to one end of the inlet and outlet pipe 5, which is always submerged below the water surface. The bypass pipe 14 is connected to a rotating shaft 15, which can rotate within the bypass pipe 14. A large wind cup 4 is connected to the upper end of the rotating shaft 15. When the wind blows towards the wind cup 4, it drives the wind cup 4 to rotate, thereby driving the rotating shaft 15 to rotate. A disc 16 is provided on the side of the lower end of the rotating shaft 15. The disc 16 has a through hole 12 with an inverted trapezoidal cross-section. The lower end of the through hole 12 is hinged to the lower end of the pusher plate 6. The disc 16 is provided with a spring 17, which pulls the pusher plate 6 to rotate in the direction of covering the through hole 12. In its natural state, the pusher plate 6 covers the through hole 12, and the upper part of the pusher plate 6 is higher than the top surface of the through hole 12. When the rotating shaft 15 rotates, it drives the water pusher plate 6 to rotate. Due to the resistance of the water, when the resistance is greater than a preset value, the water pusher plate 6 overcomes the spring 17 and rotates to open the through hole 12. Under weaker wind or no wind conditions, the rotation speed of the rotating shaft 15 is less than the first threshold, for example, the rotating shaft 15 stops rotating. The water flow resistance is insufficient to drive the water pusher plate 6 to rotate and open the through hole 12. At this time, the through hole 12 is closed, preventing water from flowing out of or into the water storage tank 3, and the planting box 2 maintains a fixed liquid level position. When the wind force increases and the rotation speed of the rotating shaft 15 is greater than the first threshold but less than the second threshold, the water flow resistance of the water pusher plate 6 causes the water pusher plate 6 to rotate, and the water pusher plate 6 opens the through hole 12. At this time, when the water pusher plate 6 rotates, it pushes the water flow downward, causing the water in the water storage tank 3 to be discharged outward. When the wind force continues to increase and reaches a strong wind state, the rotation speed of the rotating shaft 15 exceeds the second threshold, causing the water pusher 6 to rotate more vertically and continue rotating, thereby changing the direction of water pushing, so that the water pusher 6 pushes water upward. In a strong wind environment, the water pusher 6 fills the inlet and outlet pipes 5 with water. After the inlet and outlet pipes 5 are full of water, the water flows back into the water storage tank 3, increasing the gravity on the planting box 2, causing the planting box 2 to sink downward and preventing the plants 9 from being damaged by the strong wind. When the strong wind weakens into a weak wind, the water flow resistance on the water pusher 6 decreases and it returns to its original position. When the water pusher 6 rotates, it pushes the water flow downward, thereby drawing water out of the water storage tank 3, causing the planting box 2 to move upward again, and the plants 9 float to the surface. After the inlet and outlet pipes 5 are filled with water, during the process of the water tank 3 floating or sinking, if the ambient wind stops, the pusher plate 6 will close the through hole 12, preventing water from flowing through the inlet and outlet pipes 5 and avoiding the water from flowing between the water tank 3 and the ambient water under the action of gravity when there is a difference in water level. After the plant 9 floats to the surface, the pusher plate 6, under the regulation of a weak wind, drains the water from the inlet and outlet pipes 5. After the water is drained, air enters the inlet and outlet pipes 5, thus hindering the connection between the water tank 3 and the ambient water, keeping the planting box 2 floating on the water surface. The planting box 2 will only sink again when a strong wind that meets the conditions is encountered.This invention allows plants to be submerged in water during strong winds and then raised to the surface for photosynthesis once the wind subsides. In windless conditions, it maintains a relatively constant water level, preventing damage from strong winds and avoiding prolonged submersion due to lack of sunlight and oxygen. Even when alternating strong and weak winds occur, the invention keeps the plants submerged until the strong winds completely cease or the wind intensity decreases significantly over a given period. This balanced approach effectively minimizes submersion time, preventing damage from strong winds or prolonged immersion.

[0028] Specifically, the disc 16 is rotatably connected to a first connecting rod 18, which is fixedly connected to the pusher plate 6. This improves the stability of the pusher plate 6's rotation by having the first connecting rod 18 rotate together with the pusher plate 6 and change the direction of water pushing by the pusher plate 6.

[0029] Specifically, the rotating shaft 15 is provided with a protective box 19, the disc 16 is connected to the outer periphery of the protective box 19, the side wall of the protective box 19 is provided with a first through hole 20, the first through hole 20 is aligned with the first connecting rod 18, the protective box 19 is provided with a ratchet 21, a pawl 22 and a lever 23, the spring 17 includes a first torsion spring 24 and a second torsion spring 25, the elastic coefficient of the first spring 17 is less than the elastic coefficient of the second spring 17, the first torsion spring 24 is connected to the ratchet 21 and the push plate 6, or the first torsion spring 24 is connected to the ratchet 21 and the first connecting rod 18, the second torsion spring 25 is connected to the ratchet 21 and the protective box 19, the lever 23 is slidably connected to the protective box 19 and is provided with the pawl 22, the protective box 19 is provided with a spring plate 26 that pushes the pawl 22 to cooperate with the ratchet 21, when the push plate 6 covers the through hole 12, it pushes the lever 23 to disengage the ratchet 21 from the pawl 22. The protective box 19 facilitates the installation and mounting of the lever 23, ratchet 21, and pawl 22, and also protects the lever 23, ratchet 21, and pawl 22. The first connecting rod 18 passes through the first through hole 20 into the protective box 19. In strong wind conditions, the water pusher 6 drives the first connecting rod 18 to rotate, thereby deforming the first torsion spring 24 and the second torsion spring 25, which in turn drives the ratchet 21 to rotate. The lever 23 is equipped with a pawl 22. Under the push of the spring plate 26, the lever 23 engages with the ratchet 21, thereby restricting the ratchet 21 from resetting. When the pusher plate 6 changes its direction under strong wind, the ratchet 21 is stuck, limiting the effect of the second torsion spring 25 on the first connecting rod 18. Furthermore, the elastic coefficient of the first torsion spring 24 is less than that of the second torsion spring 25, and the deformation of the first torsion spring 24 is reduced. This means the force exerted by the spring 17 on the pusher plate 6 is reduced. Therefore, even when the wind force decreases after the strong wind, the pusher plate 6 can still change its direction to deliver water into the water storage tank 3, preventing the plants 9 from being damaged by the strong wind. Only after the wind force completely weakens or stops will the pusher plate 6 reset to cover the through hole 12. The reset action of the pusher plate 6 pushes the lever 23 to move, thereby causing the pawl 22 to disengage from the ratchet 21. The ratchet 21, having lost the effect of the spring 17, resets, allowing the first connecting rod 18 to be subjected to the forces of the first torsion spring 24 and the second torsion spring 25 again. Even when the tailwind of a strong wind weakens, the pusher plate 6 can still drive the water to the water storage tank 3, preventing the water in the water storage tank 3 from being discharged again after the peak of the strong wind, and ensuring that the plants 9 on the planting box 2 can be steadily sunk to the water surface after encountering strong winds.

[0030] Specifically, the lever 23 is U-shaped. One end of the lever 23 is pushed by the push plate 6, and the other end of the lever 23 is connected to the pawl 22. When the lever 23 is pushed by the push plate 6, it moves downward, causing the pawl 22 to disengage from the ratchet 21.

[0031] Specifically, the ratchet 21 has a ratchet tooth 34 on one side. With the ratchet 21 having a ratchet tooth 34 on only one side, when the ratchet 21 rotates to a threshold value, the ratchet tooth 34 engages with the pawl 22, thereby restricting the ratchet 21 from resetting. The ratchet 21 will not be jammed by the pawl 22 when rotating slightly, thus ensuring that the action of the second torsion spring 25 is restricted only after the pusher plate 6 changes its pushing direction. This solves the problem of intermittent, unstable weak winds causing a decrease in the force of the spring 17 due to changes in the pusher plate 6, ensuring the stability of the device's judgment of strong winds.

[0032] Example 2

[0033] See Figure 4In an optional implementation, one end of the lever 23 can be configured as a telescopic rod, which includes a sleeve 27, a pressure spring 28, and a movable column 29. The movable column 29 is slidably connected to the sleeve 27, and the pressure spring 28 pushes the telescopic rod to extend. The movable column 29 is provided with an upper V-shaped groove 30, a lower V-shaped groove 31, and a transition groove 32. The top of the upper V-shaped groove and the top of the lower V-shaped groove 31 are connected through the transition groove 32 to form a sliding rail. The sleeve 27 is provided with an elastic strip 33 that slides along the sliding rail. The upper V-shaped groove 30 and the lower V-shaped groove 31 are located on both sides of the elastic strip 33. When the movable column 29 is pressed, the sliding rail moves with the movable column 29, and the elastic bar 33 moves along the transition groove 32. The elastic bar 33 deforms to the right in the lower V-shaped groove and the right transition groove 32, thus generating a spring force to return to the left. The elastic bar 33 deforms to the left in the upper V-shaped groove and the left transition groove 32, thus generating a spring force to return to the right. In the initial state, the elastic bar 33 is located at the top of the upper V-shaped groove and the right transition groove 32. At this time, the elastic bar 33 is subjected to a spring force to the right. When the movable column 29 is pressed by the push plate 6, it moves downward, and the elastic bar 33 moves along the right transition groove 32. Therefore, the movable column 29 is pressed down, and the lever 23 does not cause the pawl 22 to disengage from the ratchet 21. After the push plate 6 reopens, the movable column 29 is released and reset. Due to the leftward elastic force on the elastic strip 33, it moves upward along the left side of the lower V-shaped slide groove, the left transition slide groove 32, and then returns to the top left side of the upper V-shaped slide groove 30. When the push plate 6 closes again, it pushes the movable column 29 downward. The elastic strip 33 is subjected to a rightward elastic force and slides to the bottom of the upper V-shaped slide groove. At this time, the downward sliding of the movable column 29 is restricted. When pressed, it pushes the sleeve 27 downward, causing the pawl 22 to disengage from the ratchet 21. After the push plate 6 reopens, the movable column 29 is released and reset. At this time, the elastic strip 33 is still subjected to a rightward elastic force and moves along the sliding rail groove to the initial position at the top right side of the upper V-shaped slide groove. One end of the lever 23 can be configured as a telescopic lever, which is an optional implementation scheme. By configuring one end of the lever 23 as a telescopic structure, the restriction of the ratchet 22 on the ratchet 21 can be not released when the push plate 6 is closed for the first time, and the restriction of the ratchet 22 on the ratchet 21 can be released when the push plate 6 is closed for the second time. This allows water from the outside to be transported to the water storage tank even in two weak winds after a strong wind, thus improving the safety factor of the equipment against strong winds.

[0034] Example 3

[0035] See Figures 5-6In an optional implementation, a first bevel gear 35 can be provided on the rotating shaft 15. The shaft of the wind cup 4 is connected to the input end of the differential 37. The first half-shaft 38 of the differential 37 is provided with a second bevel gear 36. The first bevel gear 35 meshes with the second bevel gear 36. The second half-shaft 39 of the differential 37 is connected to one end of the spiral spring 43, and the other end of the spiral spring 43 is fixed. The shaft of the wind cup 4 is mounted on a one-way bearing 40. When the wind cup 4 is rotated by wind force, it will drive the input shaft of the differential 37 to rotate. The two output ends of the differential 37 drive the rotating shaft 15 and the spiral spring 17 respectively. The spiral spring 17 itself has a certain preload, and the second half-shaft 39 connected to the spiral spring 43 has a large rotational resistance. When the wind cup 4 rotates at a relatively low speed, the second half-shaft 39 does not rotate, while the first half-shaft 38 rotates, driving the rotating shaft 15 and the pusher plate 6 to rotate. When the wind cup's speed increases until the pusher plate 6 rotates to its limit, the first half-shaft 38 experiences increased resistance to rotation due to the water pushing resistance. This causes the second half-shaft 39 to overcome the torque of the spiral spring 43 and rotate, storing wind energy as elastic potential energy. When the wind force decreases, the spiral spring 17 releases its elastic potential energy, driving the second half-shaft 39 to rotate in the opposite direction, thereby accelerating the rotation of the first half-shaft 38. The shaft of the wind cup 4 is mounted on a one-way bearing 40, which prevents the wind cup 4 from being driven in the opposite direction and improves the stability of the transmission. Since the spiral spring 17 does not rotate with the shaft 15, but only one end rotates to store energy, a larger spiral spring 17 with a smaller elastic modulus can be used for energy storage. Increasing the deformation of the spiral spring 17 can increase the rotation time and amount of the second half-shaft 39 when releasing elastic potential energy, thereby increasing the driving time and amount of the shaft 15. After a strong wind, it can continuously drive the water pusher 6 to rotate for a long time, absorbing the energy of the strong wind and continuing to drive the water pusher 6 to rotate during the wake of the strong wind, increasing the amount of water delivered to the drainage tank. This prevents the wind force after the peak of the strong wind from draining the water in the water storage tank 3, ensuring that the plants 9 on the planting box 2 are stably submerged below the water surface after encountering strong winds.

[0036] Optionally, the planting box 2 is provided with a base 41, and the other end of the spiral spring 43 is fixedly connected to the base 41. This facilitates the installation of the spiral spring 17.

[0037] Optionally, the spiral spring 43 is disposed inside the protective shell 42, and the sleeve 27 protects the spiral spring 17.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
