[0063] Example 1

[0064] The present embodiment provides an aeration device, as shown in Figures 1 to 5, comprising a carrier 1, a first buffer 2, a second buffer 3, a guide tube 4 and an aeration assembly, wherein the carrier 1 is suitable for being suspended in a water body, the first buffer 2 is connected to the carrier 1, the first buffer 2 has a first curved portion 21, the second buffer 3 is connected to the first buffer 2, and the second buffer 3 has a second curved portion 31. The second curved portion 31 and the first curved portion 21 enclose an arcuate flow channel, one end of the arcuate flow channel is suitable for being connected to the first curved portion 21. The guide tube 4 has a water inlet 41 and a water outlet, the water outlet is connected to the other end of the arc flow channel, and the water inlet 41 is suitable for connecting with the water body; the first buffer member 2, the second buffer member 3 and the guide tube 4 are all immersed in the water body, and the aeration assembly includes an air supply member 51 and an inflation member 52, the air supply member 51 is arranged on the carrier 1, and the air supply member 51 is connected to the inflation member 52, and the inflation member 52 is arranged in the guide tube 4, and the gas in the air supply member 51 is transported to the guide tube 4 after passing through the inflation member 52.

[0065] In the aeration device provided by the present embodiment, after the air supply member transports the gas to the guide tube 4 through the inflation member, bubbles are generated. The bubbles rise due to the buoyancy of the water body, and at the same time, the oxygen in the bubbles dissolves into the water body through the bubble wall. During the rising process, the bubbles drive the oxygenated water flow to flow upward from the water inlet 41 of the guide tube 4. Under the guidance of the guide tube 4, the water flow is transported to the arc-shaped flow channel after passing through the water outlet of the guide tube 4. Since the arc-shaped flow channel is arc-shaped, it can buffer the rising water flow, and can smoothly transform the rising water flow into a diffusion flow, thereby reducing the flow rate loss of the rising water flow, thereby increasing the diffusion range of the rising water flow after the reversal, and further expanding the oxygenation range of the aeration device.

[0066] The aeration device provided in this embodiment, as shown in Figures 2, 3 and 5, has a pancake-shaped carrier 1, and the first curved portion 21 is a curved surface formed by rotating the first arc around the axis of the carrier 1 for one circle. Taking the perspective of Figure 3 as an example, the first arc is a concave arc, and the diameter of the upper end of the first curved portion 21 is greater than the diameter of its lower end, and the diameter of the first curved portion 21 gradually decreases from the upper end to the lower end; the second curved portion 31 is a curved surface formed by rotating the second arc around the axis of the carrier 1 for one circle, and the first arc and the second arc are both quarter arcs, and the first arc and the second arc share a center, and the radius of the first arc is greater than that of the second arc; taking the perspective of Figure 2 as an example, the second arc is a concave arc, and the second curved portion The diameter of the upper end of the first curved portion 21 is greater than the diameter of the lower end, and the diameter of the second curved portion 31 gradually decreases from the upper end to the lower end. The diameter of the upper end of the first curved portion 21 is equal to the diameter of the upper end of the second curved portion 31, and the diameter of the lower end of the first curved portion 21 is smaller than the diameter of the lower end of the second curved portion 31. The lower end of the first curved portion 21 extends into the second curved portion 31. As an alternative embodiment, the spacing between the first curved portion 21 and the second curved portion 31, the diameter of the upper and lower ends of the first curved portion 21, and the diameter of the upper and lower ends of the second curved portion 31 can be adjusted according to actual installation conditions. The channel enclosed between the first curved portion 21 and the second curved portion 31 is an arcuate flow channel, which is annular. The guide tube 4 includes a cylinder and a water entry jacket. The cross-section of the cylinder can be square, rectangular, or other common shapes. In this embodiment, the cross-section of the cylinder is circular. The diameter of the lower end of the second curved portion 31 is equal to the diameter of the cylinder, and the lower end of the second curved portion 31 is integrally formed with the upper end of the cylinder. The cylinder body can be composed of multiple curved cylinder segments, and the simplified body can also be arc-shaped. In this embodiment, the cylinder body is straight and is vertically arranged in the water body. As an alternative implementation method, the tube body can be arranged according to actual construction conditions, and the upper end opening of the cylinder body is the water outlet; the water inlet jacket is adapted to the cylinder body. In this embodiment, the water inlet jacket is in the shape of an inverted frustum, and the water inlet jacket is arranged on the outer periphery of the cylinder body and is connected to the lower end opening of the cylinder body. The water inlet jacket is fixedly connected to the side wall of the cylinder body by bolts, and a number of water inlets 41 are evenly distributed on the outer peripheral side wall of the water inlet jacket. As an alternative implementation method, those skilled in the art can adjust the distribution of the water inlet 41 as needed. The water inlet 41 can be a circular hole, a square hole or a hole of other common shapes. By opening a water inlet 41 on the outer shield side wall of the water inlet jacket, it is possible to avoid opening a hole at the bottom of the water inlet jacket, thereby avoiding direct water absorption from the bottom of the water inlet jacket to cause disturbance to the bottom mud. The water inlet sleeve is shaped like an inverted frustum, preventing aquatic plants from entering the cylinder and becoming entangled with the inflatable element 52. Furthermore, because the upper diameter of the water inlet sleeve is larger than the lower diameter, any material entangled with the sleeve naturally settles due to gravity, preventing clogging of the water inlet 41. The inner wall of the guide tube 4 is coated with a hydrophobic coating, which reduces friction between the rising water and the inner wall of the guide tube 4, thereby reducing water velocity loss within the guide tube 4.

In this embodiment, the first guide portion 22 and the first curved portion 21 are integrally formed; the first guide portion 22 is fixedly connected to the bottom of the carrier 1 by bolts; the second buffer member 3 also has a second guide portion 32. The second guide portion 32 is a circular plate member, and the inner diameter, outer diameter and thickness of the second guide portion 32 and the first guide portion 22 are the same. As an alternative embodiment, the first guide portion 22 and the second guide portion 3 can be adjusted as needed. 2, the inner diameter, outer diameter, and thickness of the second guide portion 32 are equal to the diameter of the upper end of the second curved portion 31. The inner ring of the second guide portion 32 is connected to the upper end of the second curved portion 31 and smoothly transitions thereto. In this embodiment, the second guide portion 32 and the second curved portion 31 are integrally formed. The first curved portion 21 and the second curved portion 31 are both made of thin-walled materials. A hydrophobic coating can also be applied to the opposing side walls of the first curved portion 21 and the second curved portion 31, and the opposing side walls of the first guide portion 22 and the second guide portion 32 to reduce frictional resistance between the water flow and the side walls, thereby reducing water flow loss. The channel enclosed between the first guide portion 22 and the second guide portion 32 is the guide channel. The guide channel is annular, with the inlet of the curved channel connected to the water outlet, the outlet of the curved channel connected to the inlet of the guide channel, and the outlet of the guide channel connected to the water body. Through the coordination of the curved channel and the guide channel, the rising water flow can be smoothly transformed into a diffuse flow, and the flow rate loss of the water flow can be reduced.

The upper nut and the lower nut are both threadedly connected to the screw 61, and the upper nut and the lower nut are respectively located on the upper and lower sides of the second guide part 32. By adjusting the positions of the upper and lower nuts on the screw 61, the distance between the first guide part 22 and the second guide part 32 is changed, and the distance between the first curved portion 21 and the second curved portion 31 is changed. The lifting drive member 6 can drive the second buffer member 3 to approach or move away from the first buffer member 2 to adapt to the flow-pushing capacity of different inflatable members 52.

The first photovoltaic panel 81 and the second photovoltaic panel 82 are also connected to the inverter via cables, respectively, i.e., the first photovoltaic panel 81 and the second photovoltaic panel 82 can directly power the aerator.

[0079] As shown in Figures 1 to 4, the aeration device provided in this embodiment also includes three rain shields 91. This embodiment does not limit the number of rain shields 91. The rain shields 91 are fan-shaped plates that are welded and fixed to the outer wall of the cylindrical member 73. A rain shield 91 is provided between any two adjacent first photovoltaic panels 81. The rain shields 91 and the outer wall of the cylindrical member 73 enclose a rainproof cavity. The outer wall of the cylindrical member 73 located within the rainproof cavity is provided with a plurality of vents 731. The vents 731 are used for ventilation and heat dissipation of the control cabin. The rain shield 91 is used to prevent rainwater from entering the control cabin's accommodating cavity 75. The rain shield 91 has an opening 911, which faces the direction of rainwater flow on the rain shield 91. External gas can enter the accommodating cavity 75 through the opening 911 and the vents 731 in sequence.

[0080] As shown in Figure 1, the aeration device provided in this embodiment also includes a positioning pier 92, an anchor buckle 111, and an anchor chain 93. The positioning pier 92 is a pile foundation at the bottom of the water body. This embodiment does not limit the number of positioning piers 92. Those skilled in the art can install multiple positioning piers 92 and corresponding anchor chains 93 and anchor buckles 111 as needed. The anchor buckle 111 is provided on the bracket 11 and extends outside the bracket 11. One end of the anchor chain 93 is tied to the anchor buckle 111, and the other end of the anchor chain 93 is tied to the positioning pier 92, thereby fixing the carrier 1 within a certain water area.

[0081] The aeration device provided in this embodiment also includes a water quality sensor, a flow rate sensor, a control unit 94, and a signal transmitter. A water quality sensor is provided at the bottom of the aeration member 52 to provide feedback on the water quality. A flow rate sensor is provided at the bottom of the aeration member 52 to detect the flow rate of water within the guide tube 4, thereby indicating whether the water inlet 41 of the guide tube 4 is blocked. The control unit 94, which is a single-chip microcomputer or a Raspberry Pi, is placed in the control cabin and is connected to the aerator via a cable. The control unit 94 can control the power of the aerator. The water quality sensor and the flow rate sensor are electrically connected to the control unit 94 via an interface communication component or cable. The signal transmitter is connected to the control unit 94 via a cable or a communication structure component. The signal transmitter is used to communicate with an external terminal, such as a mobile phone or computer, to achieve remote monitoring and control. The communication interface component supports multiple communication protocols, including but not limited to Modbus, PROFIBUS, and OPC. When the water quality sensor indicates that the water quality has improved, the control unit 94 can reduce the power of the aerator to reduce power consumption. When the flow rate sensor reflects that the water flow rate is reduced, the control component 94 sends an alarm signal to the terminal through the signal transmitting component.

[0082] The aeration device provided in this embodiment uses bubbles generated by the aeration disk to carry oxygenated water upward, thereby achieving exchange between shallow and deep layers of the water body, thereby increasing the dissolved oxygen in the water body, inhibiting the release of sediment pollutants, enhancing the transmission efficiency of the food web, destroying the competitive advantage of cyanobacteria, and alleviating the risk of algal blooms.

[0083] The aeration device provided in this embodiment works as follows:

[0084] First, the air supply component 51 starts to work. The air supply component 51 extracts the air in the control cabin accommodating chamber 75 to generate compressed air, and transmits the compressed air to the inflatable component 52 through the aeration pipe 53. Since the pressure difference between the accommodating chamber 75 and the outside world is generated, the outside air is sequentially transmitted through the opening 911 and the vent 731 to the accommodating chamber 75. Since the air supply component 51 continuously transmits compressed air to the inflatable component, the compressed air in the inflatable component 52 is transmitted to the water body in the guide tube 4 through the micropores thereon and forms bubbles. The bubbles rise due to the buoyancy of the water body, and the oxygen in the bubbles passes through The bubble wall dissolves into the water body, and the bubbles drive the oxygenated water body to flow upward during the rising process, so that the water outside the guide tube 4 is transported into it through the water inlet 41. The rising water flow is transported to the arc flow channel through the water outlet under the diversion action of the guide tube 4, and then transported to the guide flow channel by the arc flow channel. After being guided by the arc flow channel, the rising water flow is transformed into a horizontal flow. The guide flow channel plays a transitional role so that the horizontal flow has a farther radiation area. The horizontal flow in the diversion flow channel is transported back to the water body, realizing the circulation of deep water and shallow water, and increasing the dissolved content of the water body during the circulation process.
