Pneumatic fishpond oxygen increasing device

Abstract

The invention discloses a pneumatic fishpond oxygen increasing device which comprises a rotating box body, a water suction tank and a depth positioning device. A connecting seat is fixedly connected to the lower side wall of the rotating box body, a driven bearing is fixedly connected inside the connecting seat, an inner ring of the driven bearing is in sleeved connection with the outer side of the upper portion of a main supporting pipe, a driven rotation shaft is arranged inside the main supporting pipe, the upper portion of the driven rotation shaft penetrates through the lower side wall of the rotating box body, and the upper end of the driven rotation shaft is meshed with the inner side end of a driving shaft through a gear. The lower portion of the outer side of the water suction tank is fixedly connected with the depth positioning device. The pneumatic fishpond oxygen increasing device is simple in structure, low in cost, capable of saving energy and environmentally friendly, does not use a motor and power, can be further fixed at a specific position, improves a fish stock oxygen increasing effect and has a good market promotion value.

Description

technical field [0001] The invention relates to the field of fishery equipment, in particular to a wind-powered fish pond oxygenation equipment. Background technique [0002] The level of dissolved oxygen in fish pond water is the main indicator of fish pond water quality. In order to pursue production, many fish pond farmers usually carry out excessive cultivation in fish ponds, which can easily lead to hypoxia in fish pond water. If hypoxia , the light ones affect the growth of fish, and the severe ones cause hypoxia death and cause heavy losses. Therefore, almost all farmers will purchase fish pond aerators to increase oxygen in fish pond water. [0003] However, the existing aeration equipment used in fish ponds is generally driven by electricity. This equipment is generally equipped with a high-power motor, so the manufacturing cost is relatively high, and the power consumption is large, and it is not energy-saving, which will improve the quality of the fishery industr...

AI Technical Summary

Problems solved by technology

[0003] However, the existing aeration equipment used in fish ponds is generally driven by electricity. This equipment is generally equipped with a high-power motor, so the manufacturing cost is relatively high, and the power consumption is large, and it is not energy-saving, which will improve the quality of the fishery industry. The cost of farming, and because these traditional fishery aeration equipment need electricity to work, but they are in fish ponds, it is easy to cause leakage, even some aerators with better waterproof performance, long time Occasionally, there will be leakage of water and electricity after use, and the existing aerators generally do not have a fixed position, and cannot perform fixed-point aeration in places where there are many fish schools. Therefore, the traditional aerator has many problems. limitations, and does not meet the current social theme of energy conservation and environmental protection
