Description

Technical Field

[0001] The present invention relates to an aeration device driven by wind and light, belonging to the technical field of sewage treatment. Background Art

[0002] An aeration device is a device used to aerate sewage treatment equipment. It increases the contact surface between water and oxygen, improves the dissolved oxygen content in water, thereby providing oxygen required for microorganisms in water to decompose organic matter. At the same time, it can also prevent sludge sedimentation and anaerobic phenomena, and helps to maintain the stable operation of the sewage treatment system.

[0003] Currently, the aeration devices on the market generally achieve aeration by blowing air into water or agitating the water surface. However, such devices usually require continuous power output during use and consume a large amount of electricity. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an aeration device driven by wind and light, which solves the problem of large power consumption of the aeration device in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solutions: An aeration device driven by wind and light includes a support column, the inside of the support column is hollow and is provided with an inner tube and an outer tube passing through it; a housing, including an upper housing and a lower housing, the upper housing and the lower housing are spliced and arranged above the support column, and a solar panel is provided on the outer wall surface of the upper housing; a wind power assembly, arranged above the housing; a storage battery, arranged inside the housing for storing the electric energy generated by the solar panel; wherein, the wind power assembly includes a rotating fan blade, the rotating fan blade is connected to the inner tube, the rotating fan blade is rotated by the wind and drives the inner tube to rotate, the lower end of the inner tube extends downward and is rotatably connected to a fixed rod at the end, a driver is connected to the fixed rod, and a suction fan blade is connected to the driver.

[0006] By adopting the above technical solution, it is possible to achieve autonomous power supply without an external driving power source through the wind power component and the solar panel, so that the entire device can operate throughout the day. In cooperation with the wind rotation, the power consumption of the driver can be greatly reduced, saving energy. The electric energy generated by the solar panel is stored by the storage battery to provide energy for the driver. During the operation of the entire device, it can not only capture the wind by blowing the rotating fan blades, and blow the air flow into the upper end of the support column, but also use the electric energy generated by the solar panel to provide power for the driver to drive the operation, and blow the air flow into the lower end of the support column. The two work together to drive. When the environmental wind force is large, the output power of the driver can be appropriately reduced to save energy consumption. When the environmental wind force is small, the output power of the driver can be appropriately increased to enable the device to operate stably. The external air is inhaled into the packing bed by the suction fan blades and contacts the sewage introduced into the packing bed to achieve oxygenation of the sewage.

[0007] The present invention is further configured as follows: the packing bed includes a housing, the housing is filled with graded packing, the support column is buried in the graded packing, a water spray pipe is arranged above the graded packing, an air inlet plate is arranged at the bottom of the graded packing, and the air inlet plate is connected to the bottom opening of the support column.

[0008] By adopting the above technical solution, the sewage is adsorbed by the graded packing, and at the same time, the external air can be blown into the graded packing by the wind power component to increase the dissolved oxygen content in the sewage. After the sewage is sprayed out from the water spray pipe, it penetrates into the graded packing and contacts the air flow entering from below the graded packing. Through the setting of the graded packing, the contact area between the sewage and the blown air flow is greatly increased, which can promote the dissolution speed to a certain extent.

[0009] The present invention is further configured as follows: the support column includes a pressure chamber, an exhaust chamber and an air inlet chamber from top to bottom, and exhaust holes are equidistantly arranged on the wall surface of the exhaust chamber.

[0010] By adopting the above technical solution, the air flow can enter the graded packing in a relatively uniform state, improving the diffusion speed of the air flow in the graded packing, thereby further increasing the contact rate between the air flow and the sewage. The external air flow is inhaled into the air inlet chamber by the suction fan blades, rises to the position of the exhaust chamber, and is discharged into the graded packing through the exhaust holes on the exhaust chamber.

[0011] The present invention is further configured as follows: the outer wall of the exhaust chamber is wrapped with a filter layer.

[0012] By adopting the above technical solution, the filter layer can prevent external sewage and impurities from entering the inside of the support column through the exhaust holes, affecting the stability of the device.

[0013] The present invention is further configured as follows: The wind power assembly further includes a support platform, which is connected to the upper shell. A substrate is arranged above the support platform, and the rotating fan blades are arranged on the substrate. The upper end of the inner tube extends upward and passes through the center of the substrate. The first air-catching holes are equidistantly arranged on the inner tube above the substrate. An exhaust passage is arranged on the inner wall surface at the connection point between the pressure chamber and the exhaust chamber, and the exhaust passage communicates the inner cavity of the inner tube with the exhaust chamber.

[0014] By adopting the above technical solution, the external wind force blows the rotating fan blades to rotate, and the inner tube rotates synchronously with the rotating fan blades. During the rotation of the rotating fan blades, the external air flow can enter the inner tube through the first air-catching holes, flow downward through the inner tube into the exhaust chamber, and meet the upward air flow in the air inlet chamber. Since the two air flows move in opposite directions, convection is generated, enabling the air flow to move in a direction perpendicular to the axis of the support column and be quickly discharged through the exhaust holes. Through the convection generated by the two air flows moving in opposite directions, the movement direction of the air flow is changed, enabling the air flow to be discharged from the exhaust holes at the best angle.

[0015] The present invention is further configured as follows: A plurality of arc plates are arranged in a circumferential array below the substrate. The concave surface of the arc plate faces the center of the substrate. A torsion rod is connected between the arc plate and the substrate, and a torsion spring is sleeved on the torsion rod. One end of the torsion spring is connected to the substrate, and the other end is connected to the arc plate. The greater the wind force, the greater the angle of rotation of the arc plate away from the center of the substrate. A plurality of second air-catching holes are equidistantly arranged at the upper end of the outer tube.

[0016] By adopting the above technical solution, the arc plates can improve the air-catching probability. The concave surface of the arc plate faces the center of the substrate. When the air flow blows through, under the guiding action of the concave surface of the arc plate, the flow direction of the air flow can be changed to a certain extent, causing the air flow to deflect towards the center of the substrate, thereby increasing the air volume entering the inner cavity of the outer rod through the second air-catching holes and improving the oxygenation efficiency. At the same time, a torsion spring is sleeved on the torsion rod connecting the arc plate and the substrate, enabling the arc plate to change the air-catching angle with the change of the wind force. When the wind force is large, the arc plate deflects outward by a large angle, and the interaction angle between the air flow and the arc plate approaches perpendicular, which can increase the effective force of the wind force on the arc plate. When the wind force is small, the arc plate deflects outward by a small angle, and the interaction angle between the air flow and the arc plate tends to be parallel. At this time, the air flow direction flows towards the center of the substrate under the guiding action of the concave surface of the arc plate, thereby capturing most of the oncoming air flow into the second air-catching holes.

[0017] The present invention is further configured such that: the number of the rotating fan blades is at least three, which are equidistantly arranged on the substrate, the rotating fan blades are arc-shaped and bend inwardly towards the inner tube, and the height of the blades gradually increases, and the side edge of the highest side is connected to the inner tube.

[0018] By adopting the above technical solution, when the wind energy in the external environment is relatively sufficient, the driver can be controlled to reduce the driving power. The airflow drives the inner tube to rotate by blowing the rotating fan blades, and then drives the suction fan blades connected to the lower end of the inner tube to rotate. The two cooperate with each other to achieve the co-driving of wind energy and light energy, making the driving system of the entire device more stable. The arc-shaped blades are spirally bent inwardly. The height of the side edge of the rotating fan blade at the outermost circle of the substrate is the lowest, and the height of the side edge at the innermost circle of the substrate is the highest. Each fan blade is arc-shaped and bends inwardly towards the inner tube, which not only increases the contact area between the fan blade and the air, but also enables the air to be more smoothly guided when passing through the fan blade, reducing the airflow disorder and energy loss, thereby improving the efficiency of air flow.

[0019] The present invention is further configured such that: a movable plug is provided on the outer tube, the movable plug divides the pressure chamber into upper and lower sections, the upper section of the pressure chamber is sealed, and the lower section is communicated with the exhaust chamber. A pressure sensor is provided on the movable plug, and the pressure sensor is used to monitor the pressure change in the sealed area at the upper end of the pressure chamber. The outer tube extends downward to the connection point of the pressure chamber and the exhaust chamber. The aperture of the exhaust hole gradually decreases from top to bottom. The greater the air volume, the higher the rising height of the movable plug, and the greater the pressure in the pressure chamber, and vice versa.

[0020] By adopting the above technical solution, the movable plug is used to control the pressure in the sealed area of the upper section of the pressure chamber. The greater the airflow volume blown into the support column, the higher the height that the movable plug is pushed. The pressure chamber separated by the movable plug is compressed, and the pressure increases. The movable plug rises until the pressure inside the pressure chamber is equal to the upward thrust generated after the airflow is blown in, and then the movable plug hovers at a certain point. The pressure sensor can real-time monitor the pressure in the pressure chamber, so that the device can reasonably adjust the driving force of the driver, more accurately allocate energy, make the cooperation between the wind-driven and electric-driven of the device more perfect, and achieve the best air-blowing and oxygen-increasing effect with the minimum power consumption.

[0021] The present invention is further configured such that: a flow dividing member is slidably provided on the inner tube. The flow dividing member includes a ring sleeved on the inner tube. A flow dividing plate extends outward from the middle of the ring. A plug is rotatably provided at one end of the ring. When the flow dividing member is installed, the plug faces upward.

[0022] By adopting the above technical solution, the flow splitter can further guide the two airflows entering the exhaust cavity, enabling the two airflows to generate a relatively stable convection and preventing the convection disorder caused by the excessive flow rate of the unilateral airflow. At the same time, when the external wind energy is small, the external airflow is mainly blown into the graded packing from the lower end of the support column by the suction fan blades. At this time, the flow splitter can be blown by the airflow below to the exhaust end of the outer tube, and the exhaust end of the outer tube and the exhaust channels on the inner tube are blocked by the plug head, preventing the airflow blown in from below from flowing back to the outside through the outer tube and the inner tube, and avoiding unnecessary energy loss.

[0023] The beneficial effects of the present invention are as follows: The energy provided by the wind power assembly and the solar power panel is used to drive the suction fan blades to blow air into the support column, enabling the entire device to achieve autonomous functions without being driven by an external power source. At the same time, by reasonably allocating the driving forces between the wind power assembly and the driver, when the external environmental wind energy is sufficient, the output power of the driver is reduced, and when the external environmental wind energy is low, the output power of the driver is reasonably increased, thereby realizing the stable operation of the entire device and maximizing the utilization rate of energy.

[0024] After filtering the sewage through the graded packing and blowing air into the graded packing, the contact area between the sewage and the air can be increased, enabling the oxygen in the air to fully contact the sewage in the graded packing, thereby improving the speed of sewage dissolved oxygen and greatly increasing the dissolved oxygen content of the sewage filtered through the graded packing.

[0025] Through the setting of the movable plug, the pressure chamber is divided into upper and lower sections. The pressure in the upper sealed area is monitored in real time by the pressure sensor, so as to accurately judge the convection condition of the airflow in the exhaust cavity. When the pressure sensor monitors that the pressure in the upper sealed area of the pressure chamber is small, it indicates that the airflow blown in by the wind power assembly is small and the external wind energy is small. On the contrary, it indicates that the airflow blown in by the wind power assembly is large and the external wind energy is large. Thus, the output power of the driver is reasonably regulated according to the actual situation. When the external wind energy is low, the output power of the driver is increased to supplement the required airflow by increasing the air volume blown in by the suction fan blades. When the external wind energy is high, the output power of the driver is reduced to reduce the energy loss of the storage battery. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0039] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0040] As Figure 1 and Figure 2As shown in the figure, an aeration device driven by wind and light includes a support column 2 buried in a packing bed 1. The support column 2 is hollow inside and is provided with an inner tube 3 and an outer tube 4 passing through it; a housing 5, including an upper housing 502 and a lower housing 501. After the upper housing 502 and the lower housing 501 are spliced, they are arranged above the support column 2, and a solar panel 6 is provided on the outer wall surface of the upper housing 502; a wind power assembly 7 is arranged above the housing 5; a storage battery 8 is arranged inside the housing 5 for storing the electric energy generated by the solar panel 6; wherein, the wind power assembly 7 includes a rotating fan blade 701, the rotating fan blade 701 is connected to the inner tube 3, the rotating fan blade 701 rotates by the blowing of the wind and drives the inner tube 3 to rotate. After the upper end of the inner tube 3 extends upward, a first wind-catching hole 301 is arranged at the upper end; the lower end of the inner tube 3 extends downward and is rotatably connected to a fixing rod 14 at the end, a driver 13 is connected to the fixing rod 14, and a suction fan blade 12 is connected to the driver 13.

[0041] In one embodiment, as Figure 2 shown, the present device is used in cooperation with the packing bed 1 for filtering sewage, and the entire support column 2 is inserted into the packing bed. After the sewage is preliminarily filtered by the packing bed 1, the external air is blown into the packing bed 1 through the wind power assembly 7 and the suction fan blade 12 to make full contact with the sewage, so as to achieve the purpose of increasing the oxygen content of the sewage. In the whole process, the sewage is first sprayed onto the packing bed 1 through a spraying device and gradually penetrates into the packing bed 1. Among them, graded packing 102 is added to the packing bed 1, and the packing used in the graded packing 102 is specifically sand and gravel with a filtering function. Since the graded packing 102 itself has good water permeability and stress diffusion, the sewage penetrating into the graded packing 102 is evenly diffused everywhere and makes full contact with the air in the graded packing 102 blown in through the rotating fan blade 701, thereby promoting the oxygen dissolution of the sewage and increasing the oxygen dissolution speed of the sewage.

[0042] Specifically, the packing bed 1 includes a housing 101, the graded packing 102 is wrapped by the housing 101, a bottom plate 16 is installed at the bottom of the housing 101, the support column 2 is buried in the graded packing 102, a water spray pipe 103 is arranged above the graded packing 102, an air inlet plate 15 is arranged at the bottom of the graded packing 102, the air inlet plate 15 is connected to the bottom opening of the support column 2, and a plurality of air inlet grooves are opened on the air inlet plate 15. The air inlet grooves are communicated with the outside, and the air flow enters the bottom of the packing bed 1 through the air inlet grooves and is thus sucked into the graded packing 102 through the suction fan blade 12.

[0043] By equidistantly arranging a plurality of air inlet grooves on the air inlet plate 15, the external air can be evenly transported to the bottom of the packing bed 1. At the same time, the arrangement of the plurality of air inlet grooves greatly improves the strength of the entire air inlet plate 15, and the overall strength is higher.

[0044] Furthermore, as Figure 3And Figure 4 As shown in the figure, exhaust holes 2021 are provided on the support column 2. The positions of the exhaust holes 2021 are in the middle depth area of the graded filler 102. The airflow entering the bottom of the filler tank is sucked into the inner cavity of the support column 2 by the suction fan blades 12. The airflow entering the support column 2 is discharged into the graded filler 102 through the exhaust holes 2021. Since the exhaust holes 2021 are buried in the middle area of the graded filler 102, the airflow entering the graded filler 102 can directly spread rapidly from the middle area of the graded filler 102 to the surroundings, thereby accelerating the diffusion speed of the airflow. In the wind power assembly 7, the rotating fan blades 701 can be driven by external wind force to drive the inner tube 3 to rotate. The external wind enters the inner tube 3 through the first wind-catching holes 301, flows downward through the inner cavity of the inner tube 3, and finally enters the inner cavity of the support column 2.

[0045] Since the flow direction of the airflow entering the inside of the support column 2 is along the axial direction of the support column 2, and the outlet direction of the exhaust holes provided on the wall surface of the support column 2 is perpendicular to the flow direction of the airflow. When airflows enter both above and below the support column 2, due to the convection effect generated by the encounter of the two airflows, the flow direction of the airflow changes from moving parallel to the axial direction of the support column 2 to moving perpendicular to the axial direction of the support column 2, so that the two airflows can be discharged from the exhaust holes at the best angle, improving the discharge speed of the airflow.

[0046] During the whole process, through the coordinated setting of the wind power assembly 7 and the solar power generation assembly, the whole system can realize self-power supply without an external power supply. During the operation of the whole device, it can not only capture wind by blowing the rotating fan blades 701 by wind force and blow the airflow into the upper end of the support column 2, but also use the electric energy generated by the solar panels 6 to provide power for the driver 13 to drive and operate, and blow the airflow into the lower end of the support column 2. The two work together to drive. When the environmental wind force is large, the output power of the driver 13 can be appropriately reduced to save energy consumption. When the environmental wind force is small, the output power of the driver 13 is appropriately increased to enable the device to operate stably. The external air is sucked into the packing bed 1 by the suction fan blades 12 and contacts the sewage introduced into the packing bed 1 to achieve aeration of the sewage.

[0047] As Figure 3 shown, one end of the water spray pipe 103 is connected to a water spray pump 17. The water spray pump 17 is installed and fixed on the side surface of one end of the outer shell 101 and is externally connected to a sewage tank through a water pipe. The sewage is pumped into the water spray pipe 103 by the water spray pump 17. The water spray pipe 103 is equidistantly distributed with water spray holes of the same size. The sewage is sprayed into the graded filler 102 through the water spray holes and is discharged from the drain pipe on one side of the filler tank after being filtered by the graded filler 102.

[0048] As Figure 7As shown, the support column 2 includes a pressure chamber 201, an exhaust chamber 202, and an air inlet chamber 203 from top to bottom. The exhaust holes 2021 are provided on the wall of the support column 2 at the position of the exhaust chamber 202.

[0049] Specifically, in the pressure chamber 201 section, a movable plug 11 is slidably mounted on the outer tube 4. The movable plug 11 divides the pressure chamber 201 into upper and lower sections. The upper section of the pressure chamber 201 is sealed, and the lower section is communicated with the exhaust chamber 202. A pressure sensor is provided on the movable plug 11, and the pressure sensor is used to monitor the pressure change in the sealed area at the upper end of the pressure chamber 201. The outer tube 4 extends downward to the connection point of the pressure chamber 201 and the exhaust chamber 202. The greater the air volume, the higher the height the movable plug 11 is pushed up, and the greater the pressure in the pressure chamber 201, and vice versa.

[0050] By monitoring the pressure change in the pressure chamber 201 in real time through the pressure sensor, when the pressure in the pressure chamber 201 is too high, it means that too much air flow enters the support column 2 and cannot be discharged through the exhaust holes 2021 in time. At this time, the driving power of the driver 13 is reasonably reduced, thereby reducing the air flow entering the support column 2. When the pressure in the pressure chamber 201 is too low, it means that less air flow enters the support column 2. By increasing the output power of the driver 13, the air flow rate at the bottom of the support column 2 is increased. By reasonably adjusting the real-time driving power of the driver 13, the energy utilization rate can be maximized and the ineffective loss of the entire device can be reduced.

[0051] A control module 18 is provided inside the accommodation shell 5. The storage battery 8 is specifically installed in the inner cavity of the lower shell 501, and the control module 18 is installed in the inner cavity of the upper shell 502. The control module 18 is used to control the driving of the driver 13. Among them, the pressure sensor transmits the monitoring data to the control module 18 through a wireless transmission method, and the control module 18 controls the driving power of the driver 13 by analyzing the pressure change on the pressure sensor.

[0052] In the exhaust chamber 202 section, the outer wall of the exhaust chamber 202 is wrapped with a filter layer 10. Through the setting of the filter layer 10, it is possible to prevent the filler and sewage in the graded packing 102 from entering the support column 2, and to make the air flow in the support column 2 uniformly discharged into the graded packing 102.

[0053] Furthermore, for the exhaust holes 2021 provided in the exhaust chamber 202 section, the aperture gradually decreases from top to bottom. The larger the aperture, the faster the air flow passes through. When the air flow velocity blown into the support column 2 from below by the suction fan blade 12 is relatively large, and the air flow velocity blown into the support column 2 from above by the wind power component 7 is relatively small, the air flow with a larger velocity below will blow the air flow with a smaller velocity above, causing the convection point of the two air flows to move upward, and a large amount of air flow can be discharged from the exhaust chamber 202 more quickly through the exhaust holes 2021 with a larger aperture.

[0054] Further, a flow dividing member 9 is slidably mounted on the inner rod in the air exhaust cavity 202 section. As Figure 11 shown, the flow dividing member 9 includes a circular ring 901 sleeved on the inner tube 3. A flow dividing plate 902 extends outward from the middle of the circular ring 901. A sealing head 903 is rotatably arranged at one end of the circular ring 901. The sealing head 903 is in a frustum shape. When the flow dividing member 9 is installed, the end with a smaller aperture faces upward.

[0055] As Figure 10 shown, the air flow direction of the suction fan blade 12 is towards the upper end of the support column 2. When the wind energy in the external environment is low and it is impossible to blow air into the support column 2 from above or the amount of air blown in is small, the air flow blown into the support column 2 from the bottom by the suction fan blade 12 will push the flow dividing member 9 upward until the sealing head 903 on the flow dividing member 9 is inserted into the open end of the outer tube 4, and at the same time, the air exhaust channel 302 on the inner tube 3 is blocked, preventing the air flow entering from the bottom from being discharged again through the inner tube 3 and the outer tube 4 and being unable to be discharged through the air exhaust holes 2021, resulting in ineffective air blowing.

[0056] The sealing head 903 is rotatably connected to the circular ring 901, and the fit relationship between the sealing head 903 and the inner tube 3 is a clearance fit. As the flow dividing member 9 rises and the sealing head 903 is inserted into the open end of the outer tube 4, it can prevent the upper wind power assembly 7 from being blown by a small amount of wind and causing the inner tube 3 to rotate. The sealing head 903 will not rotate synchronously with the inner tube 3, thus avoiding the sliding of the sealing head 903 against the open end of the outer tube 4 during sealing and affecting the sealing performance.

[0057] Further, the air flow plates on the flow dividing member 9 can assist in flow division. As Figure 9 shown, the arrow direction is the flow direction of the two air flows, where the black arrow represents the flow direction after the two air flows generate convection with each other. When the two air flows inside the support column 2 collide with each other, due to the blocking effect of the flow dividing plate 902, the air flow with a larger wind force will only blow the flow dividing member 9 to move, rather than directly disrupting the air flow with a smaller flow rate due to the excessive flow rate of one of the air flows, ensuring that the convection effect can be smoothly generated, and the two air flows can move along the flow dividing plate 902 without the situation of the upper and lower air flows being mixed with each other, so that the air flow can be stably discharged in a direction parallel to the air exhaust holes 2021.

[0058] As Figure 7 shown, the aperture size of the flow dividing plate 902 is equal to the aperture size of the inner wall surface of the air inlet cavity 203. When the driver 13 stops operating and the entire device realizes air blowing only by being blown by external wind energy, the flow dividing plate 902 can block the air inlet cavity 203 to prevent the air flow from being discharged through the bottom of the support column 2.

[0059] In the air inlet cavity 203 section, the driver 13 is fixed in the air inlet cavity 203. The driver 13 is specifically a dual-head motor, which is powered by the storage battery 8. One end of the drive shaft of the motor is connected to the fixed rod 14, and the other end is connected to the suction fan blade 12. By driving the suction fan blade 12 to rotate through the driver 13, the external air flow is sucked into the support column 2. By reasonably adjusting the driving power of the driver 13, the electric energy generated by the solar panel 6 can be maximally utilized.

[0060] As Figure 5 shown, the wind power assembly 7 further includes a support platform 702. The support platform 702 is connected to the upper shell 502. A substrate 703 is arranged above the support platform 702. The rotating fan blade 701 is arranged on the substrate 703. The upper end of the inner tube 3 extends upward and passes through the center of the substrate 703. The first air capture holes 301 are equidistantly arranged on the inner tube 3 above the substrate 703. An exhaust passage 302 is arranged on the wall surface of the inner tube 3 at the connection point between the pressure cavity 201 and the exhaust cavity 202. The exhaust passage 302 communicates the inner cavity of the inner tube 3 with the exhaust cavity 202.

[0061] The rotating fan blade 701 is driven by the external wind force to drive the inner tube 3 to rotate synchronously. During the rotation of the rotating fan blade 701, a part of the external air flow enters the inner cavity of the inner tube 3 through the first air capture holes 301, moves downward along the inner tube 3, and finally is discharged into the exhaust cavity 202 through the exhaust passage 302 arranged on the inner tube 3.

[0062] When the external wind energy is relatively sufficient, a large amount of air flow can be introduced into the inner tube 3 through the wind power assembly 7. At this time, the driving power of the driver 13 can be appropriately reduced to make the air flow blown into the exhaust cavity 202 reach a relatively stable amount.

[0063] Furthermore, as Figure 6 shown, a number of arc plates 704 are arranged in a circumferential array below the substrate 703. The concave surfaces of the arc plates 704 face the center of the substrate 703. A torsion rod 7041 is connected between the arc plates 704 and the substrate 703. A torsion spring 7042 is sleeved on the torsion rod 7041. One end of the torsion spring 7042 is connected to the substrate 703, and the other end is connected to the arc plate 704. The greater the wind force, the greater the angle of rotation of the arc plate 704 away from the center of the substrate 703. As Figure 8 shown, a number of second air capture holes 401 are equidistantly arranged at the upper end of the outer tube 4.

[0064] The arc plate 704 can improve the air capture probability. The concave surface of the arc plate 704 faces the center of the substrate 703. When the air flow blows through, under the guiding action of the concave surface of the arc plate 704, the flow direction of the air flow can be changed to a certain extent, so that the air flow deflects towards the center of the substrate 703, thereby increasing the air volume entering the inner cavity of the outer rod through the second air capture holes 401 and improving the oxygenation efficiency.

[0065] Further, a torsion spring 7042 is sleeved on the torsion rod 7041 for connecting the arc plate 704 and the substrate 703, so that the arc plate 704 can change the wind-catching angle with the change of wind force. When the wind force is large, the arc plate 704 deflects outward by a large angle, and the interaction angle between the air flow and the arc plate 704 approaches perpendicular, which can improve the effective force of the wind blowing the arc plate 704. When the wind force is small, the arc plate 704 deflects outward by a small angle, and the interaction angle between the air flow and the arc plate 704 tends to be parallel. At this time, the air flow direction flows towards the center of the substrate 703 through the guiding action of the concave surface of the arc plate 704, so as to capture most of the oncoming air flow into the second air-catching hole 401.

[0066] Specifically, the number of the rotating fan blades 701 is at least three, which are equidistantly arranged on the substrate 703. The rotating fan blades 701 are arc-shaped and bend inward towards the inner tube 3, and the blade height gradually increases. The side edge of the highest side is connected to the inner tube 3. When the wind energy in the external environment is relatively sufficient, the driver 13 can be controlled to reduce the driving power. The air flow drives the inner tube 3 to rotate by blowing the rotating fan blades 701, and then drives the suction fan blade 12 connected to the lower end of the inner tube 3 to rotate. The two cooperate with each other to realize the common drive of wind energy and light energy, making the drive system of the whole device more stable. The arc-shaped blades are spirally bent inward. The side edge height of the rotating fan blade 701 at the outermost circle of the substrate 703 is the lowest, and the side edge height at the innermost circle of the substrate 703 is the highest. Each fan blade is arc-shaped and bends inward towards the inner tube 3, which not only increases the contact area between the fan blade and the air, but also enables the air to be more smoothly guided when passing through the fan blade, reducing air flow disorder and energy loss, thereby improving the efficiency of air flow.

[0067] In one embodiment, as Figure 12 shown, the whole device can also be used alone. The support column 2 is in a closed state, and the exhaust hole 2021 is not provided. The air flow guiding direction of the suction fan blade 12 connected to the lower end of the inner tube 3 faces the lower end of the support column 2. The bottom of the support column 2 is fixed on the mounting table 20. The mounting table 20 is hollow inside and connected to the air blowing pipeline 19. The other end of the air blowing pipeline 19 is inserted into the water bottom. After the air flow captured by the rotating fan blade 701 enters the inner cavity of the support column 2, it quickly flows into the inner cavity of the mounting table 20 through the blowing of the suction fan blade 12, and the water body is aerated and oxygenated through the air blowing pipeline 19 into the water body.

[0068] Working principle:

[0069] For the wind power assembly 7, the external wind energy blows the rotating fan blade 701 and the arc plate 704, thereby driving the inner tube 3 to rotate. During the rotation process, a part of the air flow enters the inner cavities of the inner tube 3 and the outer tube 4 through the air capture hole one 301 and the air capture hole two 401 respectively, and moves downward along the inner tube 3 and the outer tube 4. It meets the air flow blown from the bottom of the support rod by the suction fan blade 12 in the exhaust cavity 202. After the two air flows moving in opposite directions collide with each other, the flow direction changes, making the flow direction tend to be parallel to the exhaust hole 2021, so that the air flow can be discharged into the graded filler 102 at a better angle.

[0070] For the arc plate 704, the torsion spring 7042 sleeved on the torsion rod 7041 increases the torsion amount as the wind force increases. When the external wind force is large, the torsion amount is large, the arc plate 704 deflects a large angle towards the center of the substrate 703, and the wind resistance it bears is also large. At this time, the power of the inner tube 3 is also greater. When the external wind force is small, the torsion amount is low, the arc plate 704 deflects a small angle towards the center of the substrate 703, and the wind resistance it bears is also small. At this time, the air flow impacting on the arc plate 704, under the guiding action of the arc plate 704, mostly flows towards the center of the substrate 703, and thus enters the inner cavity of the outer tube 4 through the air capture hole two 401 on the outer tube 4.

[0071] For the pressure chamber 201, when the air flow rate in the exhaust chamber 202 is large and cannot be quickly discharged through the exhaust hole 2021 in time, at this time the air flow will push the movable plug 11 upward, so that the pressure chamber 201 in the upper part of the movable plug 11 is compressed and the pressure increases. Thus, the pressure change in the pressure chamber 201 can be monitored through the pressure sensor on the movable plug 11, and then the driving power of the driver 13 can be reasonably adjusted to keep the air in the exhaust chamber 202 at the optimal amount and continuously and evenly blow the air flow into the graded filler 102.
