Description

Technical Field

[0001] The utility model relates to the technical field of oxygenators, in particular to an oxygenator with a telescopic bracket. Background Art

[0002] Aquaculture, also known as aquaculture, refers to the cultivation of fish or various seafood in artificial fish ponds on the shore for food. When aquaculture is carried out, water sprayers, waterwheels, impellers and other aerators are used to mix oxygen into the water through the blades and paddles to increase the oxygen concentration in the water and ensure that the fish in the water will not be deprived of oxygen. Publication number CN218604638U discloses an aerator, including a housing, the housing is connected to a round rod through a bearing, and an impeller is installed on the round rod. When the motor and the reducer drive the round rod to drive the impeller to rotate on the water surface, if the impeller is entangled with waterweed, it will be crushed through the contact between the impeller and the two sets of blades. If the round rod is entangled with waterweed, it will be contacted with the waterweed through multiple sets of cones at both ends of the round rod, and it can be crushed. It can effectively prevent the waterweed from entangled with the impeller and affect the work of the impeller. At the same time, it can also ensure that when the impeller hits the water surface to generate suction, the waterweed will not be entangled on the impeller, avoiding affecting its oxygenation work stability. However, the impeller on the aerator is not provided with an adjustment mechanism, which results in oxygenation only in shallow waters, thereby reducing the use effect of the aerator. The aerator still has shortcomings and needs to be improved. Utility Model Content

By setting structures such as the telescopic sleeve 6, the limiting hole 8, the mounting hole 9, the spring 10 and the limiting column 11, the limiting column 11 can be pressed to slide inside the mounting hole 9. The limiting column 11 will squeeze the spring 10 during the sliding process. After squeezing a certain distance, the limiting column 11 will move away from the limiting hole 8. After moving away, the water-lifting impeller 7 is pulled downward, so that the water-lifting impeller 7 drives the telescopic sleeve 6 to slide downward on the outer wall of the shaft 5. After sliding a certain distance, the spring 10 will bounce the limiting column 11 into another limiting hole 8, thereby improving the adjustment effect of the water-lifting impeller 7, making it convenient for operators to oxygenate waters of different depths, and effectively avoiding the problem that the inability to adjust the water-lifting impeller 7 will reduce the use effect of the aerator.

[0024] See also Figure 1-5 The limit column 11 is slidably connected to the limit hole 8, and the limit column 11 is slidably connected to the mounting hole 9. The use effect of the limit column 11 is improved through the sliding connection.
