[0023] Reference Figure 1-Figure 3 and Figure 7 , wherein, a rotating shaft 5 is rotatably connected in the water pumping cylinder 21, a water pumping impeller 51 is fixedly connected to the outer wall of the rotating shaft 5, a driving motor 52 is fixedly connected to the top of the buoyancy plate 1, and the output shaft end of the driving motor 52 is fixedly connected to the top of the rotating shaft 5, and a positioning rod 53 is fixedly connected between the bottom of the inner cavity of the water pumping cylinder 21 and the bottom of the buoyancy plate 1; a plurality of groups of fixed magnetic plates 23 are fixed at equal intervals on the inner wall of the rotating cylinder 2, and a moving magnetic plate 54 is fixedly connected to the outer wall of the rotating shaft 5, and the moving magnetic plate 54 is fixedly connected to the bottom of the buoyancy plate 1. The fixed magnetic plates 23 are magnetically attracted to each other; the bottom of the cutting cylinder 3 is fixed and connected to a liquid inlet pipe 32, the other end of the liquid inlet pipe 32 is fixedly connected to a sealing ring 33, and a rotating ring 34 is rotatably connected inside the sealing ring 33, and a plurality of groups of liquid extraction pipes 35 are arranged at equal intervals on the side wall of the rotating ring 34, and the liquid extraction pipes 35, the sealing ring 33 and the liquid inlet pipe 32 are connected, and a plurality of groups of driving rods 36 are fixed at equal intervals on the side wall of the liquid extraction pipe 35, and the other end of the driving rod 36 is fixedly connected to the side wall of the rotating cylinder 2.

[0024] Through the arrangement of the above structure, the driving motor 52 is turned on, so that the rotating shaft 5 drives the pumping impeller 51 to rotate rapidly in the water pumping cylinder 21, so that the water flow inside the water body enters the water pumping cylinder 21 along the liquid pumping pipe 35, the sealing ring 33, the liquid inlet pipe 32, the cutting cylinder 3 and the liquid guide pipe 31, and then is ejected into the air along the outlet pipe 22 and then falls back into the water body, so that the water flow inside the water body is fully in contact with the air, effectively increasing the oxygen content inside the water body, promoting the respiration of aquatic organisms and accelerating the decomposition of organic pollutants, thereby improving water quality and ensuring the ecological restoration effect of the water body; and the attraction between the moving magnetic plate 54 and the fixed magnetic plate 23 will drive the rotating cylinder 2 to rotate, and then the driving rod 36 drives multiple groups of liquid pumping pipes 35 to rotate in the water body, achieving a uniform water flow extraction effect, effectively avoiding uneven treatment inside the water body, and improving the water body restoration effect.

[0025] Reference Figure 3 、 Figure 6-Figure 8 , wherein the cutting part includes a linkage shaft 6, which is rotatably connected to the cutting cylinder 3, and two groups of linkage shafts 6 are provided in each group of cutting cylinders 3. Multiple groups of cutting blades 61 are staggered on the outer walls of the two groups of linkage shafts 6. The two groups of linkage shafts 6 are connected by a first pulley group 62. The bottom end of the rotating shaft 5 passes through the bottom of the pumping cylinder 21 and is rotatably connected to the top of the aeration box 4, and one group of linkage shafts 6 is connected to the rotating shaft 5 by a second pulley group 63.

[0026] Through the arrangement of the above structure, while the rotating shaft 5 rotates, the transmission action of the first pulley group 62 and the second pulley group 63 will cause the multiple groups of cutting blades 61 in the cutting cylinder 3 to rotate simultaneously, so as to fully cut and crush the impurities in the water flow to avoid impurities from clogging the subsequent diversion pipes, and at the same time avoid impurities from being entangled or attached to the pumping impeller 51, resulting in a decrease in pumping efficiency, thereby effectively improving the efficiency of water body ecological restoration.

[0027] Reference Figure 2-Figure 4 and Figure 7, wherein the aeration part includes two sets of sealing plates 7, which are respectively fixed on both sides of the inner cavity of the aeration box 4. Both sides of the inner cavity of the aeration box 4 are rotatably connected with reciprocating screws 71, one set of linkage shafts 6 passes through the aeration box 4 and is fixedly connected to the top of the reciprocating screw 71, and a lifting slider 72 is threadedly sleeved on the reciprocating screw 71. The lifting slider 72 is fixedly connected to the side of the sealing plate 7 facing the magnetic plate 73, and the magnetic plate 73 is in contact with the side wall of the sealing plate 7. A piston plate 74 is slidably connected in the cavity between the two sets of sealing plates 7, and there is a gap between the piston plate 74 and the magnetic plate 73. Due to magnetic attraction, multiple groups of aeration holes 75 are arranged at equal intervals on the bottom of the aeration box 4, and a one-way valve is provided in the aeration hole 75; an air inlet groove 76 is provided in the buoyancy plate 1, and the top of the air inlet groove 76 is fixed and connected to multiple groups of air inlet pipes 761, and a one-way valve is provided in the air inlet pipe 761, and an air guide groove 77 is provided in the inner cavity of the rotating shaft 5, and the two ends of the air guide groove 77 are respectively connected to the air inlet groove 76 and the inner cavity of the aeration box 4, and an air supply pipe 78 is fixedly connected to the sealing plate 7, and the two ends of the air supply pipe 78 are respectively connected to the upper and lower cavities of the aeration box 4, and a one-way valve is provided in the air supply pipe 78.

[0028] It should be noted that the one-way valve in the aeration hole 75 can only allow the gas in the lower cavity of the aeration box 4 to be filled into the water body; the one-way valve in the air inlet pipe 761 can only allow the external air flow to enter the upper cavity of the aeration box 4; and the one-way valve in the air supply pipe 78 can only allow the gas in the upper cavity of the aeration box 4 to enter its lower cavity.

[0029] By the arrangement of the above structure, when the cutting blade 61 rotates, the reciprocating screw rod 71 in the aeration box 4 is driven to rotate, so that the lifting slider 72 slides back and forth along the reciprocating screw rod 71. At this time, the piston plate 74 and the magnetic plate 73 are attracted to each other, which will synchronously drive the piston plate 74 to slide back and forth. When the piston plate 74 slides downward, the gas in the lower cavity of the aeration box 4 is compressed and the one-way valve in the aeration hole 75 is opened, so that the gas is filled into the water body along the aeration hole 75, thereby achieving aeration deeper inside the water body and further improving the ecological restoration of the water body. At the same time, when the piston plate 74 moves downward, suction is generated in the upper cavity of the aeration box 4, thereby opening the one-way valve in the air inlet pipe 761, allowing fresh air from the outside to enter the upper cavity of the aeration box 4 along the air inlet pipe 761, the air inlet groove 76 and the air guide groove 77. Subsequently, when the piston plate 74 moves upward, the gas in the upper cavity of the aeration box 4 is compressed, thereby opening the one-way valve in the air supply pipe 78, allowing the gas to pass through the air supply pipe 78 into the lower cavity of the aeration box 4, thereby realizing continuous replenishment of the aeration gas and effectively improving the aeration effect.

[0030] Reference Figure 3 、 Figure 5-Figure 7, wherein the dosing component includes a liquid storage tank 8, which is fixed on the top of the buoyancy plate 1, and the number of liquid storage tanks 8 is adapted to the water outlet pipe 22, the bottom end of the liquid storage tank 8 is fixed and connected to a liquid outlet pipe 81, the other end of the liquid outlet pipe 81 is connected to the water outlet pipe 22, and an electromagnetic valve is provided in the liquid outlet pipe 81; a stirring shaft 82 is rotatably connected in the liquid storage tank 8, and a stirring paddle 821 is rotatably connected on the outer wall of the stirring shaft 82, the bottom end of the stirring shaft 82 passes through the bottom of the buoyancy plate 1 and is fixedly connected to a friction wheel 83, and a friction ring 84 is fixedly connected between multiple groups of drive rods 36, and the friction ring 84 and the side wall of the friction wheel 83 fit together.

[0031] By setting the above structure, when the water flows out of the water outlet pipe 22, the electromagnetic valve in the liquid outlet pipe 81 is opened. At this time, due to the high flow rate of the water in the water outlet pipe 22, its pressure will be reduced (Bernoulli principle). Therefore, the water purifier in the liquid storage tank 8 will be sucked into the water outlet pipe 22 along the liquid outlet pipe 81 and discharged together, thereby more comprehensively repairing the ecology of the water body and effectively improving the water quality. In addition, while the rotating shaft 5 rotates, the transmission effect of the first pulley group 62 and the second pulley group 63 will cause the multiple groups of cutting blades 61 in the cutting cylinder 3 to rotate simultaneously. It rotates at the same time, thereby fully cutting and crushing the impurities in the water flow to prevent the impurities from clogging the subsequent diversion pipes, and at the same time preventing the impurities from being entangled or attached to the pumping impeller 51, resulting in a decrease in pumping efficiency, thereby effectively improving the water body ecological restoration efficiency; and the friction between the friction ring 84 and the friction wheel 83 will drive the stirring shaft 82 to rotate, so that the stirring paddle 821 stirs the water purifier filled in the liquid storage tank 8, so that the various components of the water purifier are evenly distributed, ensuring the use quality of the water purifier, and thus improving the water body ecological restoration effect.

[0032] Mineral purification improvers can be used in the liquid storage tank 8. This type of agent is usually composed of natural minerals, has the combined effects of physical and chemical adsorption as well as microorganisms and plants, and can remove nutrients (such as nitrogen, P phosphorus, etc.) in the water body to solve the problem of eutrophication of water bodies.

[0033] Reference Figure 1-Figure 3 Among them, an exhaust pipe 9 is fixedly connected to the top of the buoyancy plate 1, the input end of the exhaust pipe 9 is connected to the inner cavity of the water pumping cylinder 21, and the output end of the exhaust pipe 9 extends to the bottom of the buoyancy plate 1 and is fixed and connected to the thrust pipe 91.

[0034] Through the setting of the above structure, part of the water flow in the water pump 21 will be directly discharged into the water body along the exhaust pipe 9 and the thrust pipe 91, thereby utilizing the water resistance to push the buoyancy board 1 to move, realizing water ecological restoration in a larger range, and effectively improving the efficiency of water restoration.

[0035] Reference Figures 1-8In the present invention, when in use, the buoyancy board 1 is placed as a whole in the water area to be repaired, and then the driving motor 52 is turned on, so that the rotating shaft 5 drives the pumping impeller 51 to rotate rapidly in the pumping cylinder 21, so that the water flow inside the water body enters the pumping cylinder 21 along the liquid pumping pipe 35, the sealing ring 33, the liquid inlet pipe 32, the cutting cylinder 3 and the liquid guide pipe 31, and then is sprayed into the air along the outlet pipe 22 and then falls back into the water body, so that the water flow inside the water body is fully in contact with the air, effectively increasing the oxygen content inside the water body, promoting the respiration of aquatic organisms and accelerating the decomposition of organic pollutants, thereby improving water quality and ensuring the ecological restoration effect of the water body; and when the water flow is discharged from the outlet pipe 22, the electromagnetic inlet pipe 81 is turned on. Valve, at this time, due to the fast flow rate of water in the outlet pipe 22, its pressure will decrease (Bernoulli principle), so the water purifier in the liquid storage tank 8 will be sucked into the outlet pipe 22 along the outlet pipe 81 and discharged together, so as to more comprehensively repair the ecology of the water body and effectively improve the water quality; in addition, while the rotating shaft 5 rotates, the transmission effect of the first pulley group 62 and the second pulley group 63 will cause the multiple groups of cutting blades 61 in the cutting cylinder 3 to rotate at the same time, so as to fully cut and crush the impurities in the water flow, so as to avoid impurities from clogging the subsequent diversion pipelines, and at the same time avoid impurities from entangled or attached to the pumping impeller 51, resulting in a decrease in pumping efficiency, thereby effectively improving the efficiency of water body ecological restoration.

[0036] At the same time, when the rotating shaft 5 rotates, the attraction between the moving magnetic plate 54 and the fixed magnetic plate 23 will drive the rotating cylinder 2 to rotate, and then the driving rod 36 will drive multiple groups of liquid extraction pipes 35 to rotate in the water body, achieving a uniform water flow extraction effect, and a part of the water flow in the water extraction cylinder 21 will be directly discharged into the water body along the exhaust pipe 9 and the thrust pipe 91, thereby utilizing the water resistance to push the buoyancy plate 1 to move, achieving water body ecological restoration in a larger range, thereby effectively avoiding uneven treatment inside the water body, and effectively improving the water body restoration effect and efficiency; and as the driving rod 36 rotates, the friction between the friction ring 84 and the friction wheel 83 will drive the stirring shaft 82 to rotate, so that the stirring paddle 821 stirs the water purifier filled in the liquid storage tank 8, so that the various components of the water purifier are evenly distributed, ensuring the use quality of the water purifier, and thus improving the water body ecological restoration effect.

[0037] At the same time, when the cutting blade 61 rotates, it will drive the reciprocating screw rod 71 in the aeration box 4 to rotate, so that the lifting slider 72 slides back and forth along the reciprocating screw rod 71. At this time, the piston plate 74 and the magnetic plate 73 are attracted to each other, which will synchronously drive the piston plate 74 to slide back and forth. When the piston plate 74 slides downward, it will compress the gas in the lower cavity of the aeration box 4 and open the one-way valve in the aeration hole 75, so that the gas is filled into the water body along the aeration hole 75, thereby achieving aeration deeper inside the water body and further improving the ecological restoration effect of the water body. At the same time, when the piston plate 74 moves downward, suction is generated in the upper cavity of the aeration box 4, thereby opening the one-way valve in the air inlet pipe 761, allowing fresh air from the outside to enter the upper cavity of the aeration box 4 along the air inlet pipe 761, the air inlet groove 76 and the air guide groove 77. Subsequently, when the piston plate 74 moves upward, it compresses the gas in the upper cavity of the aeration box 4, thereby opening the one-way valve in the air supply pipe 78, allowing the gas to pass through the air supply pipe 78 into the lower cavity of the aeration box 4, thereby achieving continuous replenishment of aeration gas and effectively improving the aeration effect.
