Description

Technical Field

[0001] This application relates to the field of aquaculture technology, and particularly relates to an oxygenation device for aquaculture. Background Art

[0002] During aquaculture, it is usually necessary to maintain the oxygen content in the water to ensure that the fish in the water do not lack oxygen. Therefore, air needs to be introduced into the water for oxygenation to maintain the oxygen content in the water. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pond water from affecting the living environment of the fish. Currently, the oxygenation equipment on the market is mainly divided into several types such as air pump type, water gun type, and bubble type. Although these devices can improve the dissolved oxygen level of the water body to a certain extent;

[0003] Traditional oxygenation equipment often fails to achieve targeted stratified oxygenation, resulting in a situation where the bottom layer of the water body lacks oxygen while the upper layer has too high a dissolved oxygen content. Such uneven water quality not only affects the growth of aquatic organisms but also may cause the accumulation of harmful substances in the bottom layer of the water body, ultimately affecting the economic benefits and ecological safety of aquaculture. Therefore, we urgently need to provide an oxygenation device for aquaculture.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed Embodiment

[0019] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0020] An oxygenation device for aquaculture is disclosed in an embodiment of this application. Referring to Figures 1-4 , it includes a main body 1. An air pump 4 is fixedly installed inside the main body 1. The output pipe of the air pump 4 is fixedly connected to an air delivery pipe 5. The other end of the air delivery pipe 5 is connected to a four-way valve 6. Three injection pipes 7 are fixedly connected to the surface of the four-way valve 6. The other ends of the three injection pipes 7 are rotatably connected to valve covers 8. The air pump 4 provides the air source for the entire oxygenation device, and the air it outputs is transported to the four-way valve 6 through the air delivery pipe 5. The four-way valve 6 can evenly distribute the air to the three injection pipes 7 and inject it inside the valve covers 8. Three first oxygenation pipes 9 are evenly arranged at the bottom of the main body 1. Second oxygenation pipes 12 are provided inside the three first oxygenation pipes 9. Third oxygenation pipes 13 are provided inside the inner parts of the three second oxygenation pipes 12. A number of air holes 11 are evenly formed on the surfaces of the first oxygenation pipes 9, the second oxygenation pipes 12, and the third oxygenation pipes 13. The injection pipes 7 inject the air transported by the air pump 4 into the first oxygenation pipes 9, the second oxygenation pipes 12, and the third oxygenation pipes 13 in sequence, and release it into the water through the air holes 11 on the surfaces of the respective oxygenation pipes. A fixing seat 14 is fixedly installed at the bottom of the third oxygenation pipe 13. The bottom of the fixing seat 14 is of a conical structure, which is conducive to reducing resistance when adjusting up and down inside the water body. An electric cylinder 15 is installed inside the main body 1. The output end of the electric cylinder 15 penetrates the main body 1 and is connected to a telescopic rod 16. The bottom of the telescopic rod 16 is fixedly connected to the upper surface of the fixing seat 14. At the same time, the telescopic movement of the electric cylinder 15 can drive the third oxygenation pipe 13 to slide inside the second oxygenation pipe 12, and at the same time, the second oxygenation pipe 12 will also slide inside the first oxygenation pipe 9, thereby changing the positions of the air holes 11 exposed by the respective oxygenation pipes, realizing the adjustment of stratified oxygenation, so as to be able to perform targeted stratified oxygenation on the pond water, avoiding the situation of lack of oxygen at the bottom layer of the water body while the dissolved oxygen in the upper layer of the water body is too high, and improving the economic benefits and ecological safety of aquaculture.

[0021] Referring to Figures 1-4, screw threads 10 are provided on the upper surface of the upper ends of all three first aeration pipes 9. The upper ends of the first aeration pipes 9 penetrate through the bottom of the main body 1 and are respectively threadedly connected to the inner side of the valve cover 8 through the screw threads 10, which facilitates opening the tops of the first aeration pipes 9 to regularly maintain and clean the impurities inside each aeration pipe. Slide rails 17 are provided on the inner sides of both the first aeration pipe 9 and the second aeration pipe 12. Limit sliders 18 are fixedly installed on the upper surface of the upper ends of both the second aeration pipe 12 and the third aeration pipe 13. The second aeration pipe 12 is slidably connected to the inner side of the first aeration pipe 9 through the limit slider 18, and the third aeration pipe 13 is slidably connected to the inner side of the second aeration pipe 12 through the limit slider 18. Through the sliding connection between the first aeration pipe 9, the second aeration pipe 12, and the third aeration pipe 13, and the cooperation of the limit slider 18 and the slide rail 17, the second aeration pipe 12 can slide flexibly inside the first aeration pipe 9, and the third aeration pipe 13 can slide flexibly inside the second aeration pipe 12, and at the same time play a limiting role to prevent the aeration pipes from separating from each other. Three floating balls 2 are evenly fixedly connected to the outer surface of the main body 1, which can make the main body 1 float on the water surface to ensure the normal working position of the aeration device in the aquaculture area. A fixed buckle 3 is fixedly installed on the front surface of the main body 1, which is convenient for the boat to bind the main body 1, facilitating the movement, position adjustment or fixation of the aeration device, making it more stable and convenient during use, and helping to improve the efficiency of aquaculture operations.

[0022] The implementation principle of an aeration device for aquaculture in an embodiment of the present application is as follows: During specific use, first, the aeration device is tied to the tail of the boat through the fixed buckle 3. As the boat moves on the water surface, the air pump 4 inside the main body 1 works, and the air is transported through the air pipe 5 to the four-way valve 6. The four-way valve 6 distributes the air to the three injection pipes 7. The valve cover 8 on the injection pipe 7 is opened, and the air enters the first aeration pipe 9. The air holes 11 on the surfaces of the first aeration pipe 9, the second aeration pipe 12, and the third aeration pipe 13 release the air into the water to achieve preliminary aeration. When stratified aeration adjustment is required, the electric cylinder 15 is started. The telescopic rod 16 of the electric cylinder 15 drives the fixed seat 14 to move up and down, so that the third aeration pipe 13 slides inside the second aeration pipe 12, and the second aeration pipe 12 slides inside the first aeration pipe 9. In this way, the positions of the exposed air holes 11 of each aeration pipe can be changed to achieve the aeration control of different water layers and achieve the targeted stratified aeration effect.
