Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an oxygenation device for freshwater fish farming. Background Technology

[0002] Aerators are key equipment in aquaculture. They increase dissolved oxygen in the water through physical means, preventing fish from surfacing or dying due to lack of oxygen. At the same time, they inhibit the growth of anaerobic bacteria and prevent water quality deterioration. They are widely used in aquaculture, especially in high-density ponds and environments prone to oxygen deficiency such as high temperatures or rainy weather.

[0003] As disclosed in Chinese Patent Publication No. CN222751224U, an aerator for fishpond aquaculture includes a base plate, with a mounting plate fixedly connected to the top of the base plate. A water-lifting mechanism is mounted on the mounting plate. The water-lifting mechanism includes a housing, a motor, a rotating shaft, a turntable, and a fixing rod. The housing is fixedly connected to the front of the mounting plate. This invention utilizes the coordinated operation of the housing, motor, rotating shaft, turntable, fixing rod, long plate, water scoop, sliding hole, and sliding rod. When the motor starts, the turntable rotates, causing the sliding rod to move in a circular motion. Simultaneously, the sliding rod slides along the inner wall of the sliding hole, causing the long plate to drive the water scoop to swing back and forth around the hinge point, scooping up water and sprinkling it. This raises the water to a higher position, allowing it to fully contact with oxygen in the air, greatly increasing the aeration speed and improving work efficiency.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can improve the oxygenation speed and increase work efficiency, in actual use, since it is fixedly installed in the fishpond, it can only oxygenate a local space in the fishpond. The oxygenation effect is not good in areas far away from the aerator. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: an oxygenation device for freshwater fish farming, comprising a float base, a waterproof cover fixedly installed at the center of the top side of the float base, a servo motor fixedly installed inside the waterproof cover, three sets of sealing shells arranged in an array around the top side of the float base, a battery fixedly installed inside the sealing shells, an antenna fixedly installed at the top of the waterproof cover, an aeration and oxygenation component for aeration and oxygenation arranged at the bottom side of the float base, three telescopic rods fixedly arranged in an array on the outer side of the waterproof cover, connectors fixedly installed at the telescopic ends of the telescopic rods, floats fixedly installed at the bottom ends of the connectors, and anti-collision protection components arranged on the outer side of the floats.

[0006] As an optimization, the oxygenation aeration component includes a rotating shaft rotatably connected to the bottom of the output shaft of a servo motor. A rotating head is fixedly installed at the bottom of the rotating shaft. Paddle blades are arrayed on the outer side of the rotating head, and several air holes are opened through the surface of the paddle blades. By starting the servo motor, the rotating shaft will be driven to rotate, which in turn will drive the paddle blades to rotate, thereby forming a water curtain by stirring the water to increase the dissolution of oxygen.

[0007] As an optimization, the oxygenation and aeration assembly also includes a fixed rod arrayed and fixedly installed on the bottom side of the float. A protective cover is fixedly installed at the bottom end of the fixed rod, and the protective cover covers the outside of the paddle blades. The surface of the protective cover has a hollow structure.

[0008] As an optimization, the anti-collision protection component includes brackets fixedly installed on both sides of the connector. A collar is fixedly installed on the bottom side of the bracket, and a buffer spring is fixedly installed on the outer side of the collar. An anti-collision arc plate is fixedly installed on the other end of the buffer spring, and the anti-collision arc plate covers the outside of the float. The anti-collision arc plate can protect the outside of the float. When the device moves to the edge of the fishpond, it will be the first to come into contact with the impact, and then the buffer spring can be compressed for buffer protection.

[0009] As an optimization, a protective pad is glued to the outer side of the anti-collision arc plate, and the protective pad is made of rubber.

[0010] As an optimization, the telescopic rod is composed of a sleeve plate and a support plate, and the support plate is slidably inserted into the sleeve plate. The upper and lower sides of the sleeve plate are provided with through holes, and the support plate is provided with a sliding hole in the middle of one end inside the sleeve plate. A limit member is provided in the sliding hole.

[0011] As an optimization, the limiting component includes a slider slidably connected in the sliding hole, a ball embedded in the center of the slider, the ball being embedded inside the hole, a spring fixedly installed inside the sliding hole, and the slider being fixedly installed on the upper and lower sides of the spring. The spring's own elastic force will cause the upper and lower sliders to move away from each other, thereby causing the ball to be embedded inside the hole for limiting.

[0012] The beneficial effects of this utility model are:

[0013] 1. This freshwater fish aeration device, by rotating the paddle blades in the water, can increase the dissolved oxygen by creating a water curtain through agitation, activate stagnant water, and cause water to flow through the air holes in the paddle blades to form bubbles, further improving the aeration effect. At the same time, the protective cover on the outside of the paddle blades can prevent nearby fish from being sucked into the vortex and causing harm.

[0014] 2. When the aeration device for freshwater fish farming rotates the blades to aerate, the entire device will float and move freely on the water surface. When it moves to the edge of the fishpond, it will be protected by the anti-collision arc plate, which will compress the buffer spring to provide a buffering effect, thereby preventing the device from being damaged by impact when it moves freely in the fishpond.

[0020] In the description of this application, it should be understood that the terms "length", "width", "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, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1An oxygenation device for freshwater fish farming includes a float 1, a waterproof cover 2 fixedly installed at the center of the top side of the float 1, a servo motor fixedly installed inside the waterproof cover 2, three sets of sealing shells 3 arranged in an array around the top side of the float 1 and the waterproof cover 2, a battery fixedly installed inside the sealing shell 3, an antenna 4 fixedly installed at the top of the waterproof cover 2, an oxygenation and aeration component 5 for aeration and oxygenation arranged at the bottom side of the float 1, three telescopic rods 6 fixedly arranged in an array on the outer side of the waterproof cover 2, a connector 7 fixedly installed at the telescopic end of the telescopic rod 6, a float ball 8 fixedly installed at the bottom end of the connector 7, and an anti-collision protection component 9 arranged on the outer side of the float ball 8.

[0023] Please see Figure 2 The oxygenation and aeration component 5 includes a rotating shaft 10 rotatably connected to the bottom of the output shaft of a servo motor. A rotating head 11 is fixedly installed at the bottom of the rotating shaft 10. Paddle blades 12 are arrayed on the outer side of the rotating head 11, and several air holes are opened through the surface of the paddle blades 12. By starting the servo motor, the rotating shaft 10 will be driven to rotate, which in turn will drive the paddle blades 12 to rotate. This can increase the dissolution of oxygen by stirring the water and forming a water curtain. It can also activate the still water body and make the water flow through the air holes in the paddle blades 12 to form bubbles, further improving the oxygenation and aeration effect.

[0024] Please see Figure 2 The oxygenation and aeration assembly 5 also includes fixed rods 13 arrayed and fixedly installed on the bottom side of the float 1. A protective cover 14 is fixedly installed at the bottom end of the fixed rods 13, and the protective cover 14 covers the outside of the paddle blades 12. The surface of the protective cover 14 has a hollow structure. By covering the outside of the paddle blades 12 with the protective cover 14, it can play a protective role and prevent fish in the water from being sucked into the central vortex and being injured.

[0025] Please see Figure 3 The anti-collision protection component 9 includes brackets 15 fixedly installed on both sides of the connector 7. A collar 16 is fixedly installed on the bottom side of the bracket 15. A buffer spring 17 is fixedly installed on the outer side of the collar 16. An anti-collision arc plate 18 is fixedly installed on the other end of the buffer spring 17. The anti-collision arc plate 18 covers the outside of the float 8. A protective pad 19 is glued to the outside of the anti-collision arc plate 18. The protective pad 19 is made of rubber. The anti-collision arc plate 18 can protect the outside of the float 8. When the device moves to the edge of the fishpond, it will be the first to come into contact with the impact, which will then compress the buffer spring 17 for buffer protection, preventing the device from being damaged by impact when it moves freely in the fishpond.

[0026] Please see Figure 3-4The telescopic rod 6 is composed of a sleeve plate 20 and a support plate 21. The support plate 21 is slidably inserted into the sleeve plate 20. The upper and lower sides of the sleeve plate 20 are provided with through holes 22. The support plate 21 is provided with a sliding hole in the middle of one end inside the sleeve plate 20. A limiting component is provided in the sliding hole. The limiting component includes a slider 23 slidably connected in the sliding hole. A ball 24 is embedded in the center of the slider 23. The ball 24 is embedded in the inside of the through hole 22. A spring 25 is fixedly installed inside the sliding hole. The slider 23 is fixedly installed on the upper and lower sides of the spring 25. The spring 25 will drive the upper and lower sliders 23 to move away from each other, thereby driving the ball 24 to be embedded in the through hole 22 for limiting.

[0027] When in use, the buoyancy of the three sets of floats 8 makes the float 1 float on the water surface. Then, the servo motor can be started to drive the rotating shaft 10 to rotate, which in turn drives the paddle blades 12 to rotate. Therefore, a water curtain can be formed by stirring the water to increase the dissolved oxygen, and it can also activate the still water. Furthermore, the water flow can be made to form bubbles through the air holes in the paddle blades 12, further improving the oxygenation and aeration effect. At the same time, the protective cover 14 covering the outside of the paddle blades 12 can prevent nearby fish from being sucked into the vortex and causing harm.

[0028] As the blades 12 rotate, the entire device floats and moves freely on the water surface. When it moves to the edge of the fishpond, it is protected by the anti-collision arc plate 18 first, and at the same time, it compresses the buffer spring 17, which can play a buffering role.

[0029] When the support plate 21 is pulled outward, the ball 24 will be pressed and the slider 23 will slide into the sliding hole. At the same time, the spring 25 will be compressed. Therefore, after adjusting the appropriate length, the spring 25 will drive the slider 23 to reset, and the ball 24 will be repositioned in the hole 22.

[0030] In summary, this freshwater fish aeration device can increase oxygen dissolution by rotating the paddle blades 12 in the water to form a water curtain, which can also activate stagnant water. Furthermore, it can cause water to flow through the air holes in the paddle blades 12 to form bubbles, further improving the aeration effect. At the same time, the protective cover 14 covering the outside of the paddle blades 12 can prevent nearby fish from being sucked into the vortex and causing harm.

[0031] When the aeration is achieved by rotating the blades 12, the entire device will float and move freely on the water surface. When it moves to the edge of the fishpond, it will be protected by the anti-collision arc plate 18 first, and at the same time, the buffer spring 17 will be compressed, which will play a buffering role and thus prevent the device from being damaged by impact when it moves freely in the fishpond.
