Oxygen supply device for fish farm

Abstract

The invention discloses an oxygen supply device for a fish farm. The oxygen supply device for the fish farm comprises an oxygen supply device, a first air pipe is arranged on the left side of the oxygen supply device, and an oxygen outlet device is arranged at one end, far away from the oxygen supply device, of the first air pipe; the oxygen outlet device internally comprises a square block, sealing rings, a second air pipe, a cleaning mechanism and a filter screen, the number of the sealing rings is two, a sealing ring located at the top is arranged at the top of the outer surface of the square block, the sealing ring located at the bottom is arranged at the top of the inner wall of the square block, and the first air pipe penetrates through the two sealing rings and extends into the square block; according to the oxygen supply device for the fish farm, by arranging the cleaning mechanism, sand and dust accumulated on the filter screen can be cleaned, the phenomenon that the filter screen cannot be blocked and cannot be used is avoided, the flowing direction of oxygen conveyed into the filter screen can be limited through a triangular check block, and therefore the rotating efficiency of a first cylinder is improved, a spring rod is arranged; and a rotating mechanism can be in contact with the filter screen only when the oxygen flows.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an oxygen supply device for aquaculture fish farms. Background technique [0002] Fishing grounds refer to waters with fishing value where fish or other aquatic economic animals pass intensively or stay swimming. With changes in environmental conditions such as spawning and breeding, feeding and fattening, or overwintering temperature, they gather in groups in a certain season. After passing or staying in a certain water area, a relatively concentrated place with fishing value in fishery production is formed; [0003] However, because the current oxygen supply device needs to be placed at the bottom of the fishing ground, some impurities such as sand and dust at the bottom may be raised during the oxygen supply to block the oxygen supply system, which will not only make the oxygen supply device unusable, but also need to be cleaned up. Also very inconvenient, we have propose...

[0003] However, because the current oxygen supply device needs to be placed at the bottom of the fishing ground, some impurities such as sand and dust at the bottom may be raised during the oxygen supply to block the oxygen supply system, which will not only make the oxygen supply device unusable, but also need to be cleaned up. Also very inconvenient, for this reason we have proposed a kind of oxygen supply device of aquaculture fish farm
