Description

Technical Field

[0001] The invention relates to an oxygen-increasing device based on wind and solar power drive, belonging to the technical field of sewage treatment. Background Art

[0002] The oxygenation device is a device used to add oxygen to sewage treatment equipment. It increases the contact area between water and oxygen and increases the oxygen content in the water, thereby providing the microorganisms in the water with the oxygen needed to decompose organic matter. It can also prevent sludge sedimentation and the occurrence of anaerobic phenomena, helping to maintain the stable operation of the sewage treatment system.

[0003] Currently, oxygenation devices on the market generally achieve oxygenation by blowing air into the water or stirring the water surface, but such devices usually require continuous power output during use, which consumes a lot of electricity. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an oxygen-increasing device based on wind and solar drive, which solves the problem of high power consumption of oxygen-increasing devices in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: an oxygen enrichment device based on wind and solar power drive, comprising a support column, the interior of the support column is hollow and is penetrated by an inner tube and an outer tube; a containing shell, comprising an upper shell and a lower shell, the upper shell and the lower shell are spliced ​​and arranged above the support column, and a solar power generation panel is arranged on the outer wall of the upper shell; a wind power component is arranged above the containing shell; a battery is arranged inside the containing shell and is used to store the electric energy generated by the solar power generation panel; wherein the wind power component comprises rotating fan blades, the rotating fan blades are connected to the inner tube, the rotating fan blades are rotated by wind and drive the inner tube to rotate, the lower end of the inner tube extends downward and is rotatably connected to a fixing rod at the end, the fixing rod is connected to a driver, and the driver is connected to a suction fan blade.

[0006] By adopting the above technical solution, there is no need for an external driving power supply, and the wind power component and the solar power generation panel can realize self-power supply, so that the whole device can operate all day, and the rotation with wind power can greatly reduce the power consumption of the driver and save energy. The electric energy generated by the solar power generation panel is stored by the battery to provide energy for the driver. During the operation of the whole device, the rotating fan blades can be blown by wind to catch the wind and blow the airflow from the upper end of the support column, and the electric energy generated by the solar power generation panel can also be used to provide power for the driver to drive the operation and blow the airflow from the lower end of the support column. The two cooperate to drive together. 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, so that the device can operate stably. The external air is sucked into the packing bed through the suction fan blades, and contacts with 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 an outer shell, the interior of the outer shell is filled with graded filler, the support column is buried in the graded filler, a water spray pipe is arranged above the graded filler, an air inlet plate is arranged at the bottom of the graded filler, 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 filler, and the wind assembly can be used to blow the external air into the graded filler 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 filler and contacts with the airflow entering from below the graded filler. By setting the graded filler, the contact area between the sewage and the blown airflow is greatly increased, which can promote the dissolution rate to a certain extent.

[0009] The present invention is further configured as follows: the support column comprises 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 scheme, the airflow can enter the graded filler in a relatively uniform state, thereby increasing the diffusion rate of the airflow in the graded filler, thereby further increasing the contact rate between the airflow and the sewage. The external airflow is sucked into the air inlet cavity through the suction fan blades, rises to the exhaust cavity position, and is discharged into the graded filler through the exhaust holes on the exhaust cavity.

[0011] The present invention is further configured such that: the outer wall of the exhaust cavity 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 interior of the support column through the exhaust holes and affecting the stability of the device.

[0013] The present invention is further configured as follows: the wind power component also includes a support platform, the support platform is connected to the upper shell, a base plate is arranged above the support platform, the rotating fan blades are arranged on the base plate, the upper end of the inner tube extends upward and passes through the center of the base plate, the wind catching holes are equidistantly arranged on the inner tube above the base plate, an exhaust channel is arranged on the inner tube wall surface at the connection point between the pressure chamber and the exhaust chamber, and the exhaust channel connects the inner cavity of the inner tube with the exhaust chamber.

[0014] By adopting the above technical solution, the external wind force drives the rotating blades to rotate, and the inner tube rotates synchronously with the rotating blades. During the rotation of the rotating blades, the external airflow can enter the inner tube through the wind-catching hole, flow downward through the inner tube to the exhaust cavity, and after meeting the rising airflow in the air inlet cavity, convection is generated because the two airflows move in opposite directions, so that the airflow moves perpendicular to the axis direction of the support column and is quickly discharged through the exhaust hole. Convection is generated by two airflows moving in opposite directions, thereby changing the direction of the airflow, so that the airflow can be discharged from the exhaust hole at the best angle.

[0015] The present invention is further configured as follows: a plurality of cambered plates are arranged in a circular array below the substrate, the inner concave surface of the cambered plates is arranged toward the center of the substrate, a torsion rod is connected between the cambered plate and the substrate, 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 cambered plate. The greater the wind force, the greater the angle at which the cambered plate rotates away from the center of the substrate, and a plurality of wind-catching holes are equidistantly arranged on the upper end of the outer tube.

[0016] By adopting the above technical solution, the camber plate can improve the probability of wind capture, and the inner concave surface of the camber plate faces the center of the substrate. When the airflow blows through, under the guiding effect of the inner concave surface of the camber plate, the flow direction of the airflow can be changed to a certain extent, so that the airflow is deflected toward the center of the substrate, thereby increasing the amount of air entering the inner cavity of the outer rod through the second wind-catching hole, and improving the oxygenation efficiency. At the same time, a torsion spring is sleeved on the torsion rod used to connect the camber plate and the substrate, so that the camber plate can change the wind capture angle as the wind changes. When the wind is strong, the outward deflection angle of the camber plate is large, and the interaction angle between the airflow blowing and the camber plate approaches vertical, which can increase the effective force of the wind blowing the camber plate. When the wind is weak, the outward deflection angle of the camber plate is small, and the interaction angle between the airflow blowing the camber plate tends to be parallel. At this time, the airflow flows toward the center of the substrate through the guiding effect of the inner concave surface of the camber plate, thereby capturing most of the blowing airflow into the second wind-catching hole.

[0017] The present invention is further configured as follows: the number of the rotating fan blades is at least three, which are equidistantly arranged on the base plate; the rotating fan blades are curved toward the inner tube in an arc shape and the blade height gradually increases; the side edges of the highest sides are interconnected with the inner tube.

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

[0019] The present invention is further configured as follows: a movable plug is provided on the outer tube, the movable plug divides the pressure chamber into two sections, the upper section of the pressure chamber is sealed, and the lower section is connected to the exhaust chamber; a pressure sensor is provided on the movable plug, the pressure sensor is used to monitor the pressure changes in the sealing area at the upper end of the pressure chamber; the outer tube extends downward to the connection point between 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, the greater the pressure in the pressure chamber, and vice versa.

[0020] By adopting the above technical scheme, the movable plug is used to control the pressure in the upper sealing area of ​​the pressure chamber. The greater the airflow rate blown into the support column, the higher the movable plug is pushed. The pressure chamber separated by the movable plug is compressed, the pressure increases, and the movable plug rises until the pressure inside the pressure chamber is equal to the upward thrust generated by the airflow. The movable plug then hovers at a certain point, and the pressure in the pressure chamber can be monitored in real time through the pressure sensor, so that the device can reasonably adjust the driving force of the driver and distribute energy more accurately, so that the device can be more perfectly coordinated through wind drive and electric drive, and can achieve the best blowing and oxygenation effect with minimal power consumption.

[0021] The present invention is further configured as follows: a diverter is slidably arranged on the inner tube, the diverter includes a circular ring sleeved on the inner tube, a diverter plate extends outward from the middle of the circular ring, a plugging head is rotatably arranged at one end of the circular ring, and when the diverter is installed, the plugging head faces upward.

[0022] By adopting the above technical solution, the diverter can further guide the two airflows entering the exhaust cavity, so that the two airflows can produce relatively stable convection, and prevent convection turbulence caused by excessive flow rate of one side of the airflow. At the same time, when the external wind energy is small, the external airflow is mainly blown into the graded filler from the lower end of the support column through the suction fan blades. At this time, the diverter can be blown to the exhaust end of the outer tube by the airflow below, and the exhaust end of the outer tube and the exhaust channel on the inner tube are blocked by the plugging head, preventing the airflow blown in from below from flowing back to the outside through the outer tube and the inner tube, thereby avoiding unnecessary energy loss.

[0023] The beneficial effects of the present invention are as follows: the energy provided by the wind power component in conjunction with the solar power panel drives the suction fan blades to blow air into the support column, so that the entire device can realize autonomous functions without the need for external power supply to drive it. At the same time, by reasonably allocating the driving force between the wind power component and the driver, when the external environment has sufficient wind energy, the output power of the driver is reduced, and when the external environment has low wind energy, the output power of the driver is reasonably increased, thereby achieving stable operation of the entire device and maximizing energy utilization.

[0024] After filtering the sewage through the graded filler, blowing air into the graded filler can increase the contact area between the sewage and the air, allowing the oxygen in the air to fully contact the sewage in the graded filler, thereby increasing the rate of dissolved oxygen in the sewage and greatly increasing the amount of dissolved oxygen in the sewage after filtering through the graded filler.

[0025] By setting the movable plug, the pressure chamber is divided into two sections, the upper and lower sections. The pressure in the upper sealing area is monitored in real time by the pressure sensor, so that the convection condition of the airflow in the exhaust chamber can be accurately judged. When the pressure sensor detects that the pressure in the upper sealing area of ​​the pressure chamber is low, it means that the airflow flow rate blown in by the wind power component is small and the external wind energy is small. On the contrary, it means that the airflow flow rate blown in by the wind power component is large and the external wind energy is large, so as to reasonably adjust the output power of the driver according to the actual situation. When the external wind energy is low, the output power of the driver is increased, and the required airflow is supplemented 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 battery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0029] like Figure 1 and Figure 2As shown, an oxygen enrichment device based on wind and solar drive includes a support column 2, which is buried on a packing bed 1. The support column 2 is hollow inside and is penetrated by an inner tube 3 and an outer tube 4; a containing shell 5, which includes an upper shell 502 and a lower shell 501, which are spliced ​​and arranged above the support column 2, and a solar panel 6 is arranged on the outer wall of the upper shell 502; a wind power component 7, which is arranged above the containing shell 5; a battery 8, which is arranged inside the containing shell 5 and is used to store the electric energy generated by the solar panel 6; wherein the wind power component 7 includes a rotating fan blade 701, which is connected to the inner tube 3, and the rotating fan blade 701 is rotated by wind and drives the inner tube 3 to rotate. After the upper end of the inner tube 3 extends upward, a wind catching hole 301 is arranged at the upper end, and the lower end of the inner tube 3 extends downward and is rotatably connected to a fixing rod 14 at the end, and a driver 13 is connected to the fixing rod 14, and the driver 13 is connected to a suction fan blade 12.

[0030] In one embodiment, if Figure 2 As shown, the device cooperates with a packing bed 1 for filtering sewage, and the entire support column 2 is inserted into the packing bed. After the sewage is initially filtered by the packing bed 1, the external air is blown into the packing bed 1 through the wind assembly 7 and the suction fan blade 12 to fully contact the sewage, thereby achieving 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 the spray device and gradually penetrates into the packing bed 1, wherein the packing bed 1 is added with a graded filler 102, and the filler used in the graded filler 102 is specifically sand and stone with a filtering effect. Since the graded filler 102 itself has good water permeability and diffusion stress, the sewage that penetrates into the graded filler 102 is evenly diffused to all places, and is fully contacted with the air in the graded filler 102 blown in by the rotating fan blade 701, thereby promoting the dissolved oxygen of the sewage and increasing the dissolved oxygen rate of the sewage.

[0031] Specifically, the packing bed 1 includes an outer shell 101, and the graded packing 102 is wrapped by the outer shell 101. A bottom plate 16 is installed at the bottom of the outer shell 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. A plurality of air inlet slots are opened on the air inlet plate 15, and the air inlet slots are connected to the outside. The air flow enters the bottom of the packing bed 1 through the air inlet slots, and is thereby sucked into the graded packing 102 through the suction fan blades 12.

[0032] By equidistantly arranging a plurality of air inlet slots on the air inlet plate 15, 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 slots greatly improves the strength of the entire air inlet plate 15, and the overall strength is higher.

[0033] Further, such as Figure 3and Figure 4 As shown, the support column 2 is provided with an exhaust hole 2021, and the position of the exhaust hole 2021 is in the middle depth area of ​​the graded filler 102. The airflow entering the bottom of the filler groove is sucked into the inner cavity of the support column 2 through the suction fan blade 12, and the airflow entering the support column 2 is discharged into the graded filler 102 through the exhaust hole 2021. Since the exhaust hole 2021 is buried in the middle area of ​​the graded filler 102, the airflow entering the graded filler 102 can directly diffuse rapidly from the middle area of ​​the graded filler 102 to the surroundings, thereby accelerating the diffusion speed of the airflow. In the wind component 7, the rotating fan blade 701 can be driven by external wind to rotate the inner tube 3, and the external wind enters the inner tube 3 through the wind catching hole 1301, flows downward through the inner cavity of the inner tube 3, and finally enters the inner cavity of the support column 2.

[0034] Since the direction of the airflow entering the support column 2 moves along the axial direction of the support column 2, and the outlet direction of the exhaust hole arranged on the wall of the support column 2 is perpendicular to the direction of the airflow, when airflow enters both above and below the support column 2, the two airflows meet and produce convection, so that the 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 hole at an optimal angle, thereby improving the discharge speed of the airflow.

[0035] During the whole process, through the coordinated setting of the wind power component 7 and the solar power generation component, the whole system can realize self-power supply without external power supply. During the operation of the whole device, the wind can blow the rotating fan blades 701 to capture the wind and blow the airflow in from the upper end of the support column 2, and the electric energy generated by the solar power generation panel 6 can provide power for the driver 13 to drive the operation and blow the airflow in from the lower end of the support column 2. The two cooperate to drive together. When the environmental wind force is strong, the output power of the driver 13 can be appropriately reduced to save energy consumption. When the environmental wind force is weak, the output power of the driver 13 can be appropriately increased, so that the device can operate stably. The external air is sucked into the packing bed 1 through the suction fan blades 12, and contacts with the sewage introduced into the packing bed 1 to achieve the oxygenation of the sewage.

[0036] like Figure 3 As shown, one end of the water spray pipe 103 is connected to a water spray pump 17, which is fixed on the side of one end of the housing 101 and is 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, and the water spray pipe 103 is evenly 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 filtered by the graded filler 102 and discharged from the drain pipe on one side of the filler tank.

[0037] like 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, and an exhaust hole 2021 is arranged on the wall surface of the support column 2 at the position of the exhaust chamber 202 .

[0038] Specifically, in the pressure chamber 201 section, a movable plug 11 is slidably installed on the outer tube 4. The movable plug 11 divides the pressure chamber 201 into two sections, the upper section of the pressure chamber 201 is sealed, and the lower section is connected to the exhaust chamber 202. A pressure sensor is provided on the movable plug 11. The pressure sensor is used to monitor the pressure changes in the upper sealing area of ​​the pressure chamber 201. The outer tube 4 extends downward to the connection point between the pressure chamber 201 and the exhaust chamber 202. The greater the air volume, the higher the movable plug 11 is pushed up, and the greater the pressure in the pressure chamber 201, and vice versa.

[0039] The pressure sensor monitors the pressure change in the pressure chamber 201 in real time. When the pressure in the pressure chamber 201 is too high, it means that the airflow into the support column 2 is too much and cannot be discharged through the exhaust hole 2021 in time. At this time, the driving power of the driver 13 is reasonably reduced, thereby reducing the airflow into the support column 2. When the pressure in the pressure chamber 201 is too low, it means that the airflow into the support column 2 is small. By increasing the output power of the driver 13, the airflow into the bottom of the support column 2 is increased. By reasonably allocating 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.

[0040] A control module 18 is arranged inside the containing shell 5. The 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. The pressure sensor transmits monitoring data to the control module 18 via wireless transmission. The control module 18 controls the driving power of the driver 13 by analyzing the pressure changes on the pressure sensor.

[0041] The exhaust cavity 202 section has an outer wall wrapped with a filter layer 10. The filter layer 10 can prevent the filler and sewage in the graded filler 102 from entering the support column 2, and the airflow in the support column 2 is evenly discharged into the graded filler 102.

[0042] Furthermore, the exhaust holes 2021 arranged on the exhaust chamber 202 section have a gradually decreasing aperture from top to bottom. The larger the aperture, the faster the airflow passes through. When the velocity of the airflow blown in from the bottom of the support column 2 through the suction fan blades 12 is relatively high, and the velocity of the airflow blown in from the top of the support column 2 through the wind power component 7 is relatively low, the airflow with a higher velocity at the bottom will blow the airflow with a lower velocity at the top, so that the convection point of the two airflows moves upward, and a large amount of airflow can be discharged from the exhaust chamber 202 more quickly through the exhaust holes 2021 with a larger aperture.

[0043] Furthermore, a flow divider 9 is slidably mounted on the inner rod of the exhaust chamber 202 section. Fig.11 As shown, the diverter 9 includes a circular ring 901 sleeved on the inner tube 3, a diverter plate 902 extends outward from the middle of the circular ring 901, and a plugging head 903 is rotatably provided at one end of the circular ring 901. The plugging head 903 is in the shape of a truncated cone. When the diverter 9 is installed, the end with a smaller aperture faces upward.

[0044] like Fig.10 As shown, the airflow of the suction fan blades 12 is directed toward the upper end of the support column 2. When the wind energy of the external environment is low and it is impossible to blow air in from above the support column 2 or the blown air flow is small, the airflow blown in from the bottom of the support column 2 through the suction fan blades 12 will push the diverter 9 to move upward until the sealing head 903 on the diverter 9 is inserted into the open end of the outer tube 4, and at the same time the exhaust channel 302 on the inner tube 3 is blocked, preventing the airflow entering from the bottom from being re-discharged through the inner tube 3 and the outer tube 4 and being unable to be discharged through the exhaust hole 2021, resulting in ineffective blowing.

[0045] The plugging head 903 is rotationally connected to the ring 901, and the fitting relationship between the plugging head 903 and the inner tube 3 is a clearance fit. As the diverter 9 rises, the plugging head 903 is inserted into the open end of the outer tube 4, which can prevent the upper wind component 7 from being blown by a small amount of wind and causing the inner tube 3 to rotate. The plugging head 903 will not rotate synchronously with the inner tube 3, thereby avoiding the plugging head 903 from sliding with the open end of the outer tube 4 during sealing, affecting the sealing.

[0046] Furthermore, the wind flow plate on the diverter 9 can assist in diverting the flow. Fig. 9 As shown, the arrow direction is the flow direction of the two airflows, wherein the black arrow indicates the flow direction after the two airflows generate convection with each other. When the two airflows inside the support column 2 collide with each other, due to the obstruction of the diverter plate 902, the airflow with a larger wind force will only blow the diverter 9 to move, and will not directly disrupt the airflow with a smaller flow rate due to the excessive flow rate of one of the airflows, thereby ensuring that the convection effect can be smoothly generated, and the two airflows can move along the diverter plate 902 without the upper and lower airflows being mixed with each other, so that the airflow can be stably discharged in a direction parallel to the exhaust hole 2021.

[0047] like Figure 7 As shown, the aperture size of the diverter plate 902 is equal to the aperture size of the inner wall of the air inlet cavity 203. When the driver 13 stops running and the entire device is blown by external wind energy alone to achieve inflation, the diverter plate 902 can block the air inlet cavity 203 to prevent the airflow from being discharged through the bottom of the support column 2.

[0048] In the air inlet chamber 203 section, the driver 13 is fixed in the air inlet chamber 203, wherein the driver 13 is specifically a double-headed motor, which is powered by the battery 8, and one end of the driving shaft of the motor is connected to the fixing rod 14, and the other end is connected to the suction fan blade 12. The driver 13 drives the suction fan blade 12 to rotate, and the external airflow is sucked into the support column 2. By reasonably adjusting the driving power of the driver 13, the electric energy generated by the solar power generation panel 6 can be maximized.

[0049] like Figure 5 As shown, the wind power component 7 also includes a support platform 702, which is connected to the upper shell 502. A base plate 703 is arranged above the support platform 702, and the rotating fan blades 701 are arranged on the base plate 703. The upper end of the inner tube 3 extends upward and passes through the center of the base plate 703. Wind catching holes 301 are equidistantly arranged on the inner tube 3 above the base plate 703. An exhaust channel 302 is arranged on the wall of the inner tube 3 at the connection point between the pressure chamber 201 and the exhaust chamber 202. The exhaust channel 302 connects the inner cavity of the inner tube 3 with the exhaust chamber 202.

[0050] The rotating fan blades 701 are driven by external wind force to rotate synchronously, and during the rotation of the rotating fan blades 701, a part of the external airflow enters the inner cavity of the inner tube 3 through the wind catching hole 301, moves downward along the inner tube 3, and is finally discharged into the exhaust cavity 202 through the exhaust channel 302 set on the inner tube 3.

[0051] When the external wind energy is sufficient, a large amount of airflow can be introduced into the inner tube 3 through the wind power component 7. At this time, the driving power of the driver 13 can be appropriately reduced to make the airflow blown into the exhaust chamber 202 reach a relatively stable amount.

[0052] Further, such as Figure 6 As shown, there are a number of cambered plates 704 arranged in a circular array below the substrate 703, with the inner concave surface of the cambered plates 704 facing the center of the substrate 703, a torsion rod 7041 connected between the cambered plates 704 and the substrate 703, a torsion spring 7042 sleeved on the torsion rod 7041, one end of the torsion spring 7042 connected to the substrate 703, and the other end connected to the cambered plates 704, the greater the wind force, the greater the angle of rotation of the cambered plates 704 away from the center of the substrate 703. Figure 8 As shown, a plurality of wind-catching holes 401 are equidistantly arranged at the upper end of the outer tube 4 .

[0053] The curved plate 704 can increase the probability of catching wind. The inner concave surface of the curved plate 704 faces the center of the substrate 703. When the airflow blows through, the guiding effect of the inner concave surface of the curved plate 704 can change the direction of the airflow to a certain extent, so that the airflow is deflected toward the center of the substrate 703, thereby increasing the amount of air entering the inner cavity of the outer rod through the wind catching hole 401 and improving the oxygen enrichment efficiency.

[0054] Furthermore, a torsion spring 7042 is sleeved on the torsion rod 7041 used to connect the camber plate 704 and the base plate 703, so that the camber plate 704 can change the wind-catching angle as the wind changes. When the wind is strong, the camber plate 704 deflects outward at a large angle, and the interaction angle between the airflow and the camber plate 704 approaches verticality, which can increase the effective force of the wind blowing the camber plate 704. When the wind is weak, the camber plate 704 deflects outward at a small angle, and the interaction angle between the airflow and the camber plate 704 approaches parallelism. At this time, the airflow flows toward the center of the base plate 703 through the guiding effect of the inner concave surface of the camber plate 704, thereby capturing most of the blowing airflow into the wind-catching hole 2 401.

[0055] Specifically, the number of rotating blades 701 is at least three, which are equidistantly arranged on the substrate 703. The rotating blades 701 are curved toward the inner tube 3 in an arc shape and the blade height gradually increases. The side of the highest side is connected to the inner tube 3. When the wind energy in the external environment is sufficient, the driver 13 can be controlled to reduce the driving power. The airflow drives the inner tube 3 to rotate by blowing the rotating blades 701, and then drives the suction fan blades 12 connected to the lower end of the inner tube 3 to rotate. The two cooperate with each other to achieve the common drive of wind energy and light energy, making the driving system of the entire device more stable. The arc-shaped blades are spirally curved inward. The side height of the rotating blades 701 at the outermost circle of the substrate 703 is the lowest, and the side height at the innermost circle of the substrate 703 is the highest. Each blade is curved toward the inner tube 3 in an arc shape, which not only increases the contact area between the blades and the air, but also allows the air to be guided more smoothly when passing through the blades, reducing airflow turbulence and energy loss, thereby improving the efficiency of air flow.

[0056] In one embodiment, if Fig.12 As shown, the entire device can also be used alone, the support column 2 is in a closed state, and no exhaust holes 2021 are set. The airflow direction of the suction fan blades 12 connected to the lower end of the inner tube 3 is toward the lower end of the support column 2. The bottom of the support column 2 is fixed on the mounting platform 20. The interior of the mounting platform 20 is hollow and connected to the blast duct 19. The other end of the blast duct 19 is inserted into the bottom of the water. After the airflow captured by the rotating fan blades 701 enters the inner cavity of the support column 2, it quickly flows into the inner cavity of the mounting platform 20 through the blowing of the suction fan blades 12, and enters the water body through the blast duct 19 to aerate and oxygenate the entire water body.

[0057] Working principle: In the wind power component 7, the rotating fan blades 701 and the camber plate 704 are driven by external wind energy to rotate, and the inner tube 3 is driven to rotate. During the rotation, a part of the airflow passes through the wind-catching hole 1 301 and the wind-catching hole 2 401 and enters the inner cavity of the inner tube 3 and the outer tube 4 respectively, moves downward along the inner tube 3 and the outer tube 4, and meets the airflow blown in from the bottom of the support rod through the suction fan blades 12 in the exhaust cavity 202. After the two airflows with opposite moving directions collide with each other, the flow direction changes, so that the flow direction tends to be parallel to the exhaust hole 2021, so that the airflow can be discharged into the graded filler 102 at a better angle.

[0058] For the camber 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 angle of deflection of the camber plate 704 toward the center of the base plate 703 is large, the wind resistance it bears is also large, and the power of the inner tube 3 is also large. When the external wind force is small, the torsion amount is low, the angle of deflection of the camber plate 704 toward the center of the base plate 703 is small, and the wind resistance it bears is also small. At this time, most of the airflow impacting the camber plate 704 flows toward the center of the base plate 703 under the guidance of the camber plate 704, and then enters the inner cavity of the outer tube 4 through the wind-catching hole 2 401 on the outer tube 4.

[0059] For the pressure chamber 201, when the air flow in the exhaust chamber 202 is too large to be discharged quickly through the exhaust hole 2021 in time, the air flow will push the movable plug 11 to move upward, so that the pressure chamber 201 in the upper part of the movable plug 11 is compressed and the pressure increases, so that the pressure change in the pressure chamber 201 can be monitored by the pressure sensor on the movable plug 11, and then the driving power of the driver 13 can be reasonably adjusted, so that the air in the exhaust chamber 202 is maintained at an optimal amount, and the air flow can be continuously and evenly blown into the graded filler 102.
