Description

Technical Field

[0001] This invention relates to the field of lake oxygenation and aeration technology, and in particular to an oxygenation and aeration circulation device for lake water and its usage method. Background Technology

[0002] Water quality management in lakes, reservoirs, and scenic water bodies requires aeration equipment to increase dissolved oxygen and promote water circulation. Fountain aerators, due to their combined oxygenation and aesthetic appeal, are widely used in aquatic ecological restoration and are key equipment for improving black and smelly water and maintaining aquatic ecological balance. Traditional fountain aerators rely on fixed floats on the water surface, directly drawing water from the surrounding area and spraying it upwards to achieve aeration. The entire machine lacks a suspension depth adjustment structure and relies solely on the floats to maintain basic operating conditions.

[0003] The existing equipment has obvious defects. The fixed pontoon cannot adapt to changes in water level, and the nozzle is prone to sinking or spray angle deviation. In addition, it lacks an anchoring and limiting structure, and is very easy to drift and tilt under the impact of wind and waves. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides an oxygenation and aeration circulation device and its usage method for lake water, aiming to improve the problems of traditional fountain aerators having no adjustable suspension depth and being easily affected by wind and waves, causing them to drift and tilt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an oxygenation and aeration circulation device for lake water, comprising a float frame, a solar panel, a fountain aerator, and an adjustable aeration mechanism; the solar panel is disposed on the top of the float frame, and a waterproof cable is fixedly connected between the solar panel and the fountain aerator; the adjustable aeration mechanism comprises an aeration component, an adjustment component, and a fixed anchor; the aeration component is disposed on the outside of the fountain aerator, and the adjustment component is disposed on the outside of the solar panel; The aeration assembly includes a pull rope, a connecting frame, a connecting ring, an adjusting pump, and a counterweight cylinder. One end of the pull rope is connected to a fixed anchor, and the other end of the pull rope is connected to the connecting frame. The adjusting pump is fixedly installed on the top of the counterweight cylinder, and the connecting ring is fixedly installed on the top of the adjusting pump and fixedly connected to the pull rope.

[0006] The adjustment assembly includes a support frame and a temperature difference airbag. The support frame is fixed to the top of the float frame, one side of the solar panel is hinged to the support frame, and the two ends of the temperature difference airbag are respectively connected to the support frame and the solar panel.

[0007] Preferably, the counterweight cylinder is configured in the shape of a weight.

[0008] Preferably, the fountain aerator is fitted with a connecting cylinder, and the connecting frame is fixed on the outside of the connecting cylinder.

[0009] Preferably, multiple guide skirts are fixed to the outside of the connecting cylinder, and the guide skirts are located at the bottom of the fountain aerator.

[0010] Preferably, the guide skirt is arranged in an umbrella shape around the perimeter, and an arc-shaped counterweight is fixed on the side of the guide skirt away from the connecting cylinder.

[0011] Preferably, the fountain aerator has multiple obliquely arranged wind vanes fixed to its outer side.

[0012] Preferably, an annular fixing frame is fixed to the top of the connecting cylinder, and a fixing ring is fixed to the outside of the fountain aerator; the fixing ring is coaxially nested inside the fixing frame and can slide freely in the circumferential direction relative to the fixing frame; a circumferential torsion spring is provided inside the fixing frame, the fixed end of the torsion spring is fixedly connected to the inner wall of the fixing frame, and the movable end of the torsion spring is fixedly connected to the outer wall of the fixing ring.

[0013] Preferably, the solar panel is fixed with support plates on both sides, and a diagonally arranged strip-shaped reflector is fixed to one side of the support plate.

[0014] A method for using an oxygenation and aeration circulation device for lake water includes the following steps:

[0015] S1: Float the pontoon frame on the lake surface, fix one end of the rope to the anchor stone on the lake bottom, and fix the other end to the connecting frame on the outside of the fountain aerator to achieve lateral limitation of the fountain aerator.

[0016] S2: The counterweight cylinder and its top regulating pump are fixed to the pull rope via a connecting ring. Lake water is injected into the counterweight cylinder by the regulating pump to increase the total weight of the counterweight. The counterweight cylinder exerts a downward traction force on the fountain aerator through the pull rope, causing the fountain aerator to suspend at a lower depth. The lake water inside the counterweight cylinder is then pumped out by the regulating pump to reduce the total weight of the counterweight. The downward traction force of the pull rope decreases accordingly, and the fountain aerator suspends at a higher depth due to its own buoyancy. This achieves the regulation of the fountain aerator's suspension depth, ensuring that the fountain aerator always maintains a stable working posture.

[0017] S3: Utilizing the thermal expansion and contraction of the temperature difference airbag, the tilt angle of the solar panel is adaptively adjusted, and the solar panel supplies power to the fountain aerator through a waterproof cable;

[0018] S4: The fountain aerator draws water from the bottom of the lake and sprays it to the surface, allowing the water to come into contact with the air and increase oxygen, thus completing the lake's water cycle.

[0019] Preferably, in step S3, the reflector reflects light onto the surface of the solar panel, improving the power generation efficiency in low-light environments; in step S4, the guide skirt, together with the counterweight strip, gathers the bottom water to the water inlet of the fountain aerator.

[0020] The present invention has the following beneficial effects:

[0021] 1. By using an adjustable counterweight structure in conjunction with a regulating pump, the suspension depth of the aerator can be adjusted according to changes in lake water level, fundamentally solving the problem that traditional devices cannot flexibly adjust the floating height. At the same time, the lateral limiting system composed of ropes and fixed anchors can prevent the aerator from sinking due to insufficient buoyancy and the spray angle from deviating due to excessive buoyancy. It can also effectively resist the continuous impact of wind, waves and water flow, preventing the device from drifting or tilting, and keeping the aerator in a stable working posture, greatly improving the stability and accuracy of aeration operations.

[0022] 2. The umbrella-shaped guide skirt, combined with the arc-shaped counterweight, can always maintain a stable deployment state, which can efficiently collect the oxygen-deficient stagnant water at the bottom of the lake to the aerator's intake. This breaks through the limitation of traditional devices that can only extract surface water, and greatly improves the extraction and oxygenation efficiency of bottom water. The obliquely set wind vanes can drive the aerator to rotate slowly with the help of the natural wind on the lake surface, so that the fountain water column sweeps and sprays in circles, evenly spreading the oxygenated water to the surrounding surface water, realizing uniform circulation and agitation of the surface water, rapidly increasing the dissolved oxygen content of the water, and effectively improving the problem of black and smelly lake water.

[0023] 3. Relying on the physical properties of thermal expansion and contraction of the airbag, the tilt angle of the solar panel can be automatically adjusted without the need for electrical control equipment and sensors. During the day, it can maximize the light-receiving area to improve power generation efficiency, and at night it will automatically fall back to a horizontal state, which can not only avoid surface water and dirt accumulation, but also reduce the impact of wind resistance on the device. The oblique reflectors on both sides of the solar panel, together with the support plate, can be stably installed to reflect the light in low light environments such as early morning and evening to the panel surface, further improving the utilization rate of light energy, ensuring stable power supply for the device around the clock, reducing dependence on external power supply, and reducing the cost of later use and maintenance.

[0024] 4. The fixed frame, fixed ring, and torsion spring form a buffer self-recovering structure, which can effectively absorb the instantaneous impact force brought by wind, waves, and water flow, and prevent the aerator from being deformed or damaged by external force. When the device is deviated by external force, the torsion spring can generate a rebound force to drive the aerator to automatically reset, continuously maintain a stable aeration working state, greatly reduce the probability of device failure, improve the durability of the device in the complex outdoor environment of lakes, and effectively extend the overall service life.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1, refer to Figures 1-9An oxygenation and aeration circulation device for lake water includes a float frame 100, a solar panel 110, a fountain aerator 200, and an adjustable aeration mechanism 300. The float frame 100 provides stable floating support for the entire device. The solar panel 110 is located on top of the float frame 100, and a waterproof cable 120 is fixedly connected between the solar panel 110 and the fountain aerator 200. The waterproof cable 120 enables safe underwater power transmission and avoids leakage faults. The adjustable aeration mechanism 300 includes an aeration component 320, an adjustment component 330, and a fixing anchor 310. The aeration component 320 is located outside the fountain aerator 200 and is used to regulate the working state of the aerator. The adjustment component 330 is located outside the solar panel 110. The aeration component 320 is used to optimize the light-receiving effect of the solar panel. It includes a pull rope 321 and a counterweight cylinder 322. One end of the pull rope 321 is connected to a fixed anchor 310. The fixed anchor 310 is submerged at the bottom of the lake to prevent the device from drifting. The counterweight cylinder 322 is set on the pull rope 321 and can adjust the suspension height of the fountain aerator 200 by its own weight. The adjustment component 330 includes a support frame 331 and a temperature difference airbag 332. The support frame 331 is fixed to the top of the float frame 100. One side of the solar panel 110 is hinged to the support frame 331. The two ends of the temperature difference airbag 332 are respectively connected to the support frame 331 and the solar panel 110. The temperature difference airbag 332 can expand and contract with temperature changes, automatically adjusting the light-receiving angle of the solar panel 110 and improving the light energy utilization efficiency.

[0038] The aeration component 320 adjusts the actual suspension depth of the fountain aerator 200. By changing the weight of the counterweight in the counterweight cylinder 322, it can maintain a more ideal working posture on the water surface. This can prevent the nozzle from sinking due to insufficient buoyancy and prevent the spray angle from deviating due to excessive buoyancy. At the same time, the counterweight cylinder 322 and the pull rope 321 can form a reliable lateral limit, making it less likely for the fountain aerator 200 to tilt or drift under the disturbance of wind and water flow, further improving the stability of the water surface operation.

[0039] The adjustment component 330, hinged to the support frame 331, allows the solar panel 110 to change angle around the fulcrum. Thermostatic bladder 332 acts as a driving element, automatically adjusting the tilt angle of the solar panel 110 according to changes in ambient temperature. When sunlight intensifies and the ambient temperature rises during the day, the gas inside the thermostatic bladder 332 expands due to heat, increasing the bladder's length and pushing the free end of the solar panel 110 upwards. This allows the solar panel 110 to naturally rise and form a larger tilt angle, achieving a better light-receiving direction and improving light energy collection efficiency. Conversely, at night or during cloudy or rainy weather, the ambient temperature decreases, causing the gas inside the thermostatic bladder 332 to contract, reducing the bladder's length and allowing the solar panel 110 to slowly tilt under its own weight. The device returns to a near-horizontal position to prevent water accumulation and reduce the impact of wind resistance on the device. The temperature difference airbag 332 is used to automatically adjust the tilt angle of the solar panel 110 according to changes in ambient temperature. Its interior can be filled with air, inert gas, or a gas mixture with a certain expansion coefficient. The airbag body can be made of flexible rubber, TPU film, or weather-resistant composite film material to ensure that it can maintain good expansion and contraction performance and sealing performance in long-term outdoor exposure. The two ends of the temperature difference airbag 332 are fixedly connected to the support frame 331 and the free end of the solar panel 110, respectively. When working, it can produce reversible expansion and contraction changes in the length direction, and its deformation directly affects the tilt angle adjustment of the solar panel 110.

[0040] The aeration assembly 320 also includes an adjusting pump 323 and a connecting ring 324. The adjusting pump 323 is fixedly installed on the top of the counterweight cylinder 322, which can quickly pump out and drain the water inside the counterweight cylinder 322, flexibly changing the counterweight weight. Through the adjusting pump 323, the water or gas inside the counterweight cylinder 322 can be pumped out or injected according to the actual working conditions, so that the overall weight of the counterweight cylinder 322 can be adjusted during use. When it is necessary to increase the sinking depth of the fountain aerator 200, the adjusting pump 323 can be used to pump gas into the counterweight cylinder. Lake water is injected into the counterweight cylinder 322, making it heavier and generating a stable downward traction force. Conversely, when it is necessary to increase the floating height of the fountain aerator 200, the water in the counterweight cylinder 322 can be discharged by adjusting the pump 323 to reduce its weight. The connecting ring 324 is fixed to the top of the adjusting pump 323 and fixedly connected to the pull rope 321 to ensure stable transmission of the counterweight traction force. The counterweight cylinder 322 is designed in the shape of a weight, which can reduce underwater resistance, allow gravity to act vertically, and improve the accuracy of depth adjustment.

[0041] Example 2, refer to Figures 1-9 Based on Embodiment 1, the fountain aerator 200 is equipped with a connecting cylinder 326, and a connecting frame 325 is fixed on the outside of the connecting cylinder 326. The end of the pull rope 321 is fixedly connected to the connecting frame 325, so that the limiting force of the pull rope 321 is more uniform and stable.

[0042] Multiple guide skirts 327 are fixed on the outside of the connecting cylinder 326. The guide skirts 327 are located at the bottom of the fountain aerator 200. When the water pump of the fountain aerator 200 is working, the guide skirts 327 can guide the bottom water flow to the central water inlet, forming a flow convergence effect from the outside to the inside, thereby effectively increasing the proportion of bottom water being pumped up, so that the water volume carried by the fountain spray contains more deep oxygen-deficient water, thereby improving the overall oxygenation efficiency.

[0043] The guide skirt 327 is arranged in an umbrella shape to form a complete flow-gathering space, comprehensively collecting the bottom water. An arc-shaped counterweight 328 is fixed to the side of the guide skirt 327 away from the connecting cylinder 326. The counterweight 328 uses its own weight to press down on the guide skirt 327, keeping it in an extended state and preventing it from curling up due to water flow impact, thus continuously ensuring the flow-gathering effect. The counterweight 328 is used to keep the guide skirt 327 stable and extended underwater. Through the gravity of the counterweight 328, each guide skirt 327 can avoid significant upward flipping or curling up when impacted by water flow or when the fountain aerator 200 rotates, ensuring that the guide skirt 327 remains stable in the water. Maintaining a preset downward tilt angle ensures that the bottom water flow can gather towards the central intake along the umbrella-shaped guide direction. When the fountain aerator 200 is pumping water, each guide skirt 327 forms an independent convergence channel underwater. Multiple guide skirts 327 together form a circumferential converging structure, causing the surrounding water to flow from the outside to the inside and be efficiently sucked into the fountain aerator 200 by the water pump, achieving stable pumping of deep water. The position and weight of the counterweight 328 ensure that the guide skirt 327 can maintain its umbrella-shaped unfolding form when disturbed by waves, avoiding damage to the convergence path due to the skirt floating, and ensuring that the bottom water flow can continuously and evenly converge towards the central area of ​​the fountain.

[0044] Multiple obliquely arranged wind vanes 329 are fixed to the outside of the fountain aerator 200. The wind vanes 329 can generate lateral thrust with the help of the natural wind on the lake surface, causing the fountain aerator 200 to rotate slowly. This causes the fountain water column to sweep and spray in a circle, evenly dispersing the oxygenated water to the surrounding surface water, improving the oxygenation uniformity of the local surface water. The oblique angle of the wind vanes 329 allows them to form an effective force-bearing surface under different wind directions, and they will not fail due to changes in wind direction, thus ensuring that the fountain aerator 200 always has a stable rotational driving force. The multiple wind vanes 329 are distributed circumferentially, and the wind force is superimposed through their respective tilt angles, forming a relatively uniform rotational push on the fountain aerator 200, so that the fountain water column can cover a larger water area in a slow sweeping manner during operation.

[0045] A ring-shaped fixing frame 3210 is fixed to the top of the connecting cylinder 326, and a fixing ring 3211 is fixed to the outside of the fountain aerator 200. The fixing ring 3211 is coaxially nested inside the fixing frame 3210 and can slide freely in the circumferential direction relative to the fixing frame 3210. A circumferential torsion spring 3212 is provided inside the fixing frame 3210. The fixed end of the torsion spring 3212 is fixedly connected to the inner wall of the fixing frame 3210, and the movable end of the torsion spring 3212 is fixedly connected to the outer wall of the fixing ring 3211. When the fountain aerator 200 is impacted by wind and waves, the traction force of the pull rope 321 changes, or the wind vane 329 drives it to rotate, the fixing ring... 3211 will generate displacement inside the fixed frame 3210. The torsion spring 3212 will generate circumferential torsional deformation synchronously with the circumferential sliding of the fixed ring 3211. The torsional deformation will store energy to absorb the instantaneous impact of the external force, reduce the damage of the impact to the device structure, and prevent the fountain aerator 200 from swinging or tilting significantly when subjected to force. When the external force applied to the fixed ring 3211 is removed, the torsion spring 3212 releases the stored elastic torque, generates a reset torque opposite to the offset direction, drives the fixed ring 3211 to rotate in the opposite direction circumferentially, so that the fixed ring 3211 rotates back to the initial working position and maintains a stable working posture.

[0046] The solar panel 110 is fixed with support plates 333 on both sides, providing a stable mounting base for the side components. A diagonally positioned strip-shaped reflector 334 is fixed to one side of the support plate 333. The reflector 334 reflects weak light in the early morning and late afternoon onto the surface of the solar panel 110, effectively improving power generation efficiency and ensuring stable power supply. The reflector 334 can be made of a metal-coated plate, a weather-resistant plastic reflector, or a composite reflective material. Its surface has a high reflectivity, which can redirect side- or low-angle incident light back to the surface of the solar panel 110. This increases the light-receiving area and light energy utilization of the solar panel 110 during periods of high light intensity, such as early morning, late afternoon, or when the angle of shadow changes significantly. The reflector 334 is fixedly connected to the support plate 333, preventing it from shaking or shifting under wind or wave disturbances, ensuring accurate reflection. The effect is stable and reliable. Through the light compensation effect of the reflector 334, even if the direction of light received by the solar panel 110 changes during the adjustment of the tilt angle of the solar panel 110 by the temperature difference airbag 332, the reflector 334 can still provide additional light to the panel according to its fixed tilt angle, so that the solar panel 110 can maintain higher power generation efficiency in all-weather light change environment. In addition, the reflector 334 forms a certain shield on both sides of the solar panel 110, making it difficult for side-floating debris or water droplets splashed by waves to directly cover the surface of the solar panel 110, which helps to reduce panel contamination and water accumulation. The strip-shaped reflector 334 has the advantages of light weight, low wind resistance and flexible arrangement, which enables it to provide side supplementary light to the solar panel 110 without significantly increasing the wind load on the float frame 100.

[0047] Example 3, referring to Figures 1-9 A method for using an oxygenation and aeration circulation device for lake water includes the following steps:

[0048] S1: Place the float frame 100 stably and float it on the surface of the target operation area of ​​the lake, so that the float frame 100 provides a stable water support foundation for the whole device. Place the fixed anchor 310 at the corresponding position on the bottom of the lake. Use the pull rope 321 to firmly connect the fixed anchor 310 on the bottom of the lake to the connecting frame 325 on the outside of the fountain aerator 200, forming an all-round lateral limit constraint on the fountain aerator 200. Relying on the gravity of the fixed anchor 310 and the traction force of the pull rope 321, it resists the continuous impact of wind and waves and water flow on the lake surface, and avoids the device from drifting, tilting or overturning during operation, ensuring that the device is always fixed at the preset operation point and operates stably.

[0049] S2: The counterweight cylinder 322 and its top regulating pump 323 are fixed to the pull rope 321 via the connecting ring 324. Based on the real-time water level of the lake, the regulating pump 323 pumps or injects water to change the overall weight of the counterweight cylinder 322. Relying on the gravitational pull of the counterweight cylinder 322 on the pull rope 321, the suspension depth of the fountain aerator 200 on the water surface is adjusted. Lake water is injected into the counterweight cylinder 322 via the regulating pump 323 to increase the total weight of the counterweight. The counterweight cylinder 322 exerts a downward force on the fountain aerator 200 through the pull rope 321. The traction force reduces the suspension depth of the fountain aerator 200; by adjusting the pump 323 to extract lake water from the counterweight cylinder 322 to reduce the total weight of the counterweight, the downward traction force of the pull rope 321 decreases accordingly, and the suspension depth of the fountain aerator 200 increases under its own buoyancy; this ensures that the nozzle of the fountain aerator 200 is always at the optimal working height, which not only avoids the nozzle being submerged and aeration failure due to rising water level, but also prevents the nozzle from being too high and the spray angle from deviating due to excessive buoyancy, so that the fountain aerator 200 always maintains a stable and standard working posture;

[0050] S3: Utilizing the physical property of thermal expansion and contraction of the temperature difference airbag 332 with ambient temperature, the tilt angle of the solar panel 110 can be adaptively adjusted without electrical control equipment. When the temperature rises during the day, the temperature difference airbag 332 expands and pushes the solar panel 110 upward to maximize the light-receiving area and improve the light energy collection efficiency. When the temperature drops at night, the temperature difference airbag 332 contracts and drives the solar panel 110 back down, reducing surface water accumulation and wind resistance. The solar panel 110 converts light energy into electrical energy, which is continuously and stably supplied to the fountain aerator 200 and regulating pump 323 through the waterproof cable 120. The waterproof cable 120 can realize underwater sealed power transmission, eliminate the risk of leakage, and ensure the power supply safety of the device.

[0051] S4: After the fountain aerator 200 is powered on and started, it draws out the stagnant water that is deficient in oxygen and eutrophic at the bottom of the lake and sprays the water upward into the air, so that the water and air can fully contact and mix, quickly increasing the dissolved oxygen content of the water and completing the water oxygenation operation. The oxygenated water falls back to the lake surface, driving the flow of the surrounding water and efficiently realizing the exchange and whole-area circulation of the water between the upper and lower layers of the lake.

[0052] In step S3, the strip-shaped reflectors 334 on the side support plates 333 of the solar panel 110 can reflect the lateral and low-angle light in low light environments such as early morning and evening onto the surface of the solar panel 110, making up for the lack of light and significantly improving the power generation efficiency in low light environments. This ensures that the device can still provide stable power supply under adverse light conditions such as rain, dawn and dusk, and achieve uninterrupted operation around the clock. In step S4, the umbrella-shaped guide skirt 327 at the bottom of the connecting cylinder 326 is stably deployed under the gravity of the arc counterweight bar 328, efficiently gathering the large area of ​​oxygen-deficient bottom water to the water inlet of the fountain aerator 200, greatly improving the suction efficiency of the stagnant bottom water. At the same time, the wind vanes 329 obliquely set on the outside of the fountain aerator 200 generate continuous lateral thrust with the help of the natural wind on the lake surface, causing the fountain aerator 200 to slowly rotate around its own center, so that the fountain water column sprays in a sweeping circle, spreading the oxygenated water to the surrounding surface water, improving the oxygenation uniformity and coverage effect of the water.

[0053] Working principle: The float frame 100 floats on the lake surface, serving as the overall load-bearing structure to support the solar panel 110 and the fountain aerator 200. The waterproof cable 120 securely connects the solar panel 110 and the fountain aerator 200, completing the sealed power transmission. The anchor stone 310 is placed at the bottom of the lake. One end of the pull rope 321 is connected to the anchor stone 310, and the other end is connected to the connecting frame 325 on the outside of the fountain aerator 200. The connecting frame 325 is fixed to the outside of the connecting cylinder 326, forming a lateral limiting system to prevent the device from drifting due to wind and waves. The counterweight cylinder 322 is fixed to the pull rope 321 by the connecting ring 324. The regulating pump 323 is installed at the top of the counterweight cylinder 322, which can draw lake water into or out of the counterweight cylinder 322, changing the overall weight of the counterweight cylinder 322. The suspension depth of the fountain aerator 200 is precisely controlled by the traction force of the pull rope 321. The support frame 331 is fixed to the top of the float frame 100. One side of the solar panel 110 forms a hinge structure with the support frame 331. The two ends of the temperature difference airbag 332 are connected to the support frame 331 and the solar panel 110 respectively. The temperature difference airbag 332 will expand and contract with changes in ambient temperature, pushing the solar panel 110 to rotate around the hinge point, realizing the self-adaptive adjustment of the tilt angle of the solar panel 110 without electrical control. The top of the connecting cylinder 326 is fixed with a fixing frame 3210. The fountain aerator 200 is equipped with a fixing ring 3211. The fixing ring 3211 slides against the inside of the fixing frame 3210. The torsion spring 3212 inside the fixing frame 3210 is connected to the fixing ring 3211, which can buffer the impact force brought by wind and waves, allowing the fountain aerator 200 to automatically rebound to a stable working posture after being deflected by force.

[0054] After the fountain aerator 200 is powered on and started, it draws oxygen-deficient water from the bottom of the lake and sprays it upwards. The water is sprayed to the lake surface and comes into full contact with the air, completing the dissolved oxygenation operation. Multiple guide skirts 327 on the outside of the connecting cylinder 326 are distributed at the bottom of the fountain aerator 200. The guide skirts 327 are arranged in an umbrella shape around the perimeter. An arc-shaped counterweight bar 328 is fixed to the side of the guide skirt 327 away from the connecting cylinder 326. The counterweight bar 328 presses down on the guide skirt 327 by its own weight, keeping the guide skirt 327 in a stable and extended state. This continuously gathers the surrounding bottom water to the water inlet of the fountain aerator 200, greatly improving the efficiency of drawing out stagnant water from the bottom. Multiple obliquely arranged wind vanes 329 are fixed to the outside of the fountain aerator 200. The wind vanes 329 generate lateral thrust under the influence of lake winds, causing the fountain aerator 200 to rotate slowly, resulting in a circular spray of water that evenly disperses the oxygenated water to the surrounding surface water, achieving uniform circulation of the local surface water and enhancing the oxygenation effect. Support plates 333 are fixed to both sides of the solar panel 110. An obliquely arranged strip-shaped reflector 334 is fixed to one side of each support plate 333. The reflector 334 reflects lateral and low-angle incident light onto the surface of the solar panel 110, improving power generation efficiency in low-light conditions such as early morning and evening, continuously providing stable power to the fountain aerator 200 and regulating pump 323, ensuring stable operation of the device around the clock.
