[0002] Crabs are rich in protein and have become a popular dish in recent years due to their delicious meat and versatility in cooking. To boost economic benefits, many farmers use breeding boxes for crab farming, which have low investment costs and are easy to harvest. However, the small space in the breeding boxes results in low oxygen levels in the water, which is not conducive to crab growth. Therefore, farmers use oxygenation devices to ensure the oxygen content inside the breeding boxes.

[0003] In the prior art, CN212414380U discloses an oxygenation device for crab farming. The oxygenation mechanism can be moved up and down by a support rod, which facilitates the adjustment of the position of the oxygenation mechanism in the tank and makes it convenient to oxygenate the farming water at different depths in the tank, thus improving the usage effect. However, this device can only adjust the height of the oxygenation mechanism, and the range of action of the oxygenation mechanism is limited, so the oxygenation effect needs to be further improved. Therefore, we disclose an oxygenation device for crab farming water to meet people's needs. Utility Model Content

[0017] 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.

[0018] Example: Reference Figure 1-4The device shown is an aeration device for crab farming water, comprising a box 1. An L-shaped fixing frame 2 is installed on the inner wall of the box 1. A waist-shaped sliding hole 3 is vertically opened on one side of the L-shaped fixing frame 2. A rotating hole is opened on the top side of the L-shaped fixing frame 2. A threaded rod 4 is provided on one side of the L-shaped fixing frame 2. The non-threaded section of the threaded rod 4 is rotatably matched with the rotating hole. A turntable 5 is installed at the top of the threaded rod 4. An internal threaded sleeve 6 is screwed onto the threaded rod 4. A connecting rod 7 is installed on the outer wall of the internal threaded sleeve 6. The connecting rod 7 is slidably matched with the waist-shaped sliding hole 3. A fixing block 9 is installed at one end of the 7. Two rotating shafts 10 are rotatably mounted side by side on the top side of the fixing block 9. A rotating rod 11 is sleeved on each of the two rotating shafts 10. A first air outlet pipe 16 is installed at one end of each of the two rotating rods 11. A second air outlet pipe 8 is slidably sleeved on each of the two first air outlet pipes 16. Both the first air outlet pipe 16 and the second air outlet pipe 8 are polygonal pipes, and multiple air outlet micro-holes are opened on their outer side walls. A fixing unit is installed between the first air outlet pipe 16 and the second air outlet pipe 8, and a limiting unit is installed between the two first air outlet pipes 16.

[0019] Based on the above structure, the two first air outlet pipes 16 are rod-shaped, which can guide the gas to a farther position and increase the oxygenation range. By rotating the threaded rod 4 through the turntable 5, the inner threaded sleeve 6 and the connecting rod 7 move up and down along the waist-shaped sliding hole 3, realizing the height adjustment of the two first air outlet pipes 16. The two first air outlet pipes 16 rotate along the rotating shaft 10 with the two rotating rods 11, which can make the two first air outlet pipes 16 form a certain angle, thereby making the water in the tank 1 more evenly oxygenated. The second air outlet pipe 8 slides out along the first air outlet pipe 16, which can make the gas reach a farther area. Thus, the overall length of the air outlet pipe can be adjusted according to the size of the tank 1 to improve the oxygenation effect.

[0020] like Figure 3 As shown, the limiting unit includes a limiting rod 14. Multiple insertion holes 15 are provided on one side of the limiting rod 14. Fixing posts 13 are installed on the top sides of the two first air outlet pipes 16. The limiting rod 14 is located on the top side of the two first air outlet pipes 16, and the two fixing posts 13 are inserted and matched with the corresponding insertion holes 15. Through the setting of the limiting rod 14, the multiple insertion holes 15 on the limiting rod 14 are arranged in a straight line. Two insertion holes 15 at corresponding distances can be selected and fitted onto the corresponding two limiting rods 14, thereby limiting the angle between the two first air outlet pipes 16.

[0021] like Figure 3 As shown, gears 12 are fitted onto both rotating shafts 10. The two gears 12 mesh with each other. By setting the gears 12, when one of the first air outlet pipes 16 is rotated, the other rotating shaft 10 rotates synchronously under the meshing action, and drives the rotating rod 11 and the corresponding first air outlet pipe 16 to rotate, so that the two first air outlet pipes 16 can rotate synchronously.

[0022] like Figure 3 and 4 As shown, the fixing unit includes a T-shaped pin 18. A sliding hole is provided on the top side of the second air outlet pipe 8 near the end of the first air outlet pipe 16. The T-shaped pin 18 is slidably installed in the sliding hole. A plurality of limiting grooves 17 are correspondingly provided on the top side of the first air outlet pipe 16. One end of the T-shaped pin 18 is inserted into the corresponding limiting groove 17. After the second air outlet pipe 8 slides to a suitable position, one end of the T-shaped pin 18 is inserted into the corresponding limiting groove 17 to restrict the movement of the second air outlet pipe 8 and realize the fixing function.

[0023] like Figure 4 As shown, a tension spring 19 is fitted on the T-pin 18. One end of the tension spring 19 is installed on the top side of the second air outlet pipe 8, and the other end is installed on one side of the T-pin 18. The tension of the tension spring 19 can pull the T-pin 18 to automatically insert into the corresponding limiting groove 17, and at the same time prevent the T-pin 18 from sliding into the limiting groove 17.

[0024] like Figure 4 As shown, a pull ring 20 is installed at the top of the T-pin 18, which facilitates the pulling of the T-pin 18 and increases the ease of operation.

[0025] like Figure 4 As shown, an annular groove is provided on the first vent pipe 16 at one end near the second vent pipe 8. A sealing ring 21 is fitted inside the annular groove. The outer side of the sealing ring 21 matches the inner wall of the second vent pipe 8. The sealing ring 21 can increase the sealing between the first vent pipe 16 and the second vent pipe 8, thereby preventing gas leakage and allowing gas to flow out through the micropores, thus generating bubbles better.

[0026] Working principle of this utility model: The two first air outlet pipes 16 are rod-shaped, which can guide the gas to a farther position and increase the oxygenation range. By rotating the threaded rod 4 through the turntable 5, the inner threaded sleeve 6 and the connecting rod 7 move up and down along the waist-shaped sliding hole 3 to realize the height adjustment of the two first air outlet pipes 16. The two first air outlet pipes 16 rotate along the rotating shaft 10 with the two rotating rods 11, which can make the two first air outlet pipes 16 form a certain angle, thereby making the water in the tank 1 more evenly oxygenated. The second air outlet pipe 8 slides out along the first air outlet pipe 16, which can make the gas reach a farther area. Thus, the overall length of the air outlet pipe can be adjusted according to the size of the tank 1 to improve the oxygenation effect.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
