[0002] In the field of aquaculture technology, aerators are commonly used to oxygenate the water to ensure sufficient oxygen levels. Currently, commonly used aerators utilize electricity to drive impellers, creating splashes that allow the water to come into contact with oxygen from the air. However, these aerators not only consume a lot of energy and incur high aquaculture costs, but they also cannot address the issue of oxygenation in deep water. Therefore, this application proposes an aerator powered by wind energy to achieve deep-water oxygenation, fully utilizing renewable natural wind resources and reducing aquaculture costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figure 1 As shown, the deep-water wind-powered circulating aerator for aquaculture includes a positioning mechanism, a wind-powered drive mechanism, a main shaft 1, a water storage tank 2, and a water supply pipe 3. The main shaft is rotatably connected to the positioning mechanism located in the water. The top of the main shaft is connected to the wind-powered drive mechanism, and the bottom is connected to the water storage tank, which is located above the water surface. Multiple sprinkler pipes 4 arranged in a circular array are connected to the outer periphery of the water storage tank. The bottom of the water storage tank is connected to the water supply pipe, which contains shaftless spiral blades 5. Figure 1The opening on the side wall of the water supply pipe is only to show the internal shaftless spiral blade structure (it is actually a closed structure). The present invention is placed in the water using a positioning mechanism. Wind power is used as the power source to drive the wind power drive mechanism to rotate, thereby driving the main shaft 1 to rotate along the positioning mechanism. The main shaft 1 drives the shaftless spiral blade 5 and the water supply pipe 4 to rotate synchronously. The spiral direction of the shaftless spiral blade 5 matches the rotation direction of the water supply pipe 4. The blade will apply an axial force to the water in the deep water area, overcome its gravity, and push the water upward along the water supply pipe 4 to the water storage tank 2. The water in the water storage tank 2 is sprayed out of the sprinkler pipe 4 under the action of centrifugal force, thereby achieving the purpose of oxygenation.

[0029] A gear transmission mechanism is provided between the bottom end of the main shaft 2 and the water storage tank. The gear transmission mechanism includes a gearbox 6, a gear set, and a driven shaft tube 7. The gearbox is connected to the positioning mechanism, and its upper and lower ends are rotatably connected to the main shaft and the driven shaft tube, respectively. The gearbox includes a housing 601 and a cover 602. The housing is located at the top of the housing and is assembled and connected by screws 11. The cover is also assembled and connected to the positioning mechanism by screws, which facilitates disassembly and maintenance. The main shaft 2 and the driven shaft tube 7 are connected by a gear set located in the gearbox. The driven shaft tube is connected to the water storage tank. The upper end of the water storage tank is provided with a cover plate 12. The cover plate is connected to the driven shaft tube, and the cover plate and the water storage tank are assembled and connected by screws. The gear set includes an external gear disk 8, a transition gear 9, and a central gear 10 that mesh sequentially. A transition plate 21 is connected to the bottom of the main shaft, and the transition plate is connected to the external gear disk by screws. The central gear 10 is connected to the driven shaft tube 7. The external gear disk 8 is annular, with the transition gear 9 and the central gear 10 located inside it. The diameter of the external gear disk is larger than that of the transition gear 9 and the central gear 10, thereby allowing the central gear 10 and the driven shaft tube 7 to obtain a higher rotational speed, achieving the purpose of speed change. This allows the present invention to achieve continuous oxygenation even under low wind conditions. Bearings are installed at the rotating connections between the main shaft and the positioning mechanism and the gearbox, and bearings are also installed at the rotating connections between the driven shaft tube and the gearbox to improve the smoothness of rotational motion.

[0030] The positioning mechanism includes a positioning post 13, a lifting sleeve 14, a floating frame 15, and a float 16. The floating frame connects the lifting sleeve and the float. The lifting sleeve is slidably connected to the positioning post fixed in the water. Utilizing the buoyancy of the water on the float, the lifting sleeve floats up and down along the positioning post as the water level changes, ensuring the device is always at a suitable height. A limiting member 21 is provided at the upper part of the positioning post to limit the lifting height of the lifting sleeve, preventing the lifting sleeve from falling off the positioning post due to excessively high water levels. There is at least one positioning post and one lifting sleeve. To improve the stability of the floating frame's position, multiple positioning posts and matching lifting sleeves can be provided, each lifting sleeve sliding up and down along its corresponding positioning post. Multiple floats are arranged in a circular array around the main axis. In this embodiment, there are three floats arranged in a triangular pattern, ensuring the overall structural stability.

[0031] The wind power drive mechanism includes a rotating frame 17 and multiple wind power drive hemispheres 18. The rotating frame is rotatably mounted on the top of the main shaft and connected to multiple wind power drive hemispheres arranged in a circular array around the main shaft. The three wind power drive hemispheres are hemispherical and evenly distributed, which can effectively capture wind and use it as power to drive rotation, thereby improving the utilization rate of wind energy.

[0032] The bottom end of the water supply pipe is connected to a water filter cylinder 19. Multiple filter hole groups are evenly distributed on the side wall of the water filter cylinder. Each filter hole group contains multiple filter holes 20 distributed in an arc shape. The arc direction of the arc matches its rotation direction, which improves the water flow efficiency. At the same time, due to the small hole diameter, it can effectively prevent fish, aquatic plants or other debris in the water from entering the water supply pipe and causing blockage.

[0033] The working principle of this utility model is as follows:

[0034] This invention utilizes a positioning column 13 fixed in a designated water area. The buoyancy of the water on the float 16 causes the lifting sleeve 14 to float up and down along the positioning column 13 with changes in water level, ensuring that the invention is always at a suitable height. The wind-driven hemisphere 18 captures wind within the water area and uses the wind power to drive its rotation, thereby driving the main shaft 1 to rotate. The gearbox 6 then uses gears to achieve speed change, increasing the rotational speed of the driven shaft tube 7 and the water supply pipe 3, lifting the deep water from the lower layer upwards and transporting it to the water storage tank 2. The centrifugal force generated by the rotation of the water storage tank 2 is used to spray water onto the surrounding water surface, thereby achieving the purpose of oxygenation. This process is repeated, and the upper and lower layers of water circulate and oxygenate each other.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
