Air bubble type oxygen-enriching machine in fish pond

Abstract

The invention relates a bubble-typed pound automatic aerator, which comprises a motor, flexible tubes and an air pump. The air pump comprises a tube-shaped cylinder and a tube-shaped piston arranged in the cylinder. The tube-shaped cylinder is opened with a gap at one end, and the other end is sealed, an air outlet is opened at the sealed end, and an air outlet valve is arranged on the air outlet. The air outlet is connected with a main flexible tube by an air outlet tube, and the main flexible tube is also connected with a branch organ, a plurality of branch flexible tubes are connected on the branch organ, a shower-shaped nozzle is connected with the end part of the branch flexible tube, and a dobber is tied on the nozzle. The bubble-typed pound automatic aerator is characterized by large amount of supplied air, even distribution of the amount of air, low energy consumption, etc. By the reciprocated movement of the piston, fresh air can be sent to water continually. Meanwhile, the nozzle thereof is placed at the water bottom, thus many small bubbles can be produced, and the bubbles can combine with water fast and closely and dissolve in water, therefore, fast oxygenation can be offered to the rearing ponds, and fishes can obtain continuous enough oxygen.

Description

technical field [0001] The invention relates to a fish pond aeration device, in particular to a bubble type fish pond aeration machine. Background technique [0002] The aeration equipment sold on the market and used in rural areas are all impeller-type, which float on the water surface through the buoyancy of four floating balls. The oxygenation effect of the pond is not ideal. In addition, there is another unsatisfactory disadvantage, that is, the fish pond aeration equipment completely depends on the external power supply. Once a power failure occurs, this impeller type fish pond aeration equipment cannot be used. Due to the current poor quality of power supply in rural areas, power outages often occur. Therefore, when fish lack oxygen and encounter power outages, farmers can only watch helplessly as their fish ponds turn over and die. The large economic loss made the farmers sad and worried: they had no income for a year from fish farming, but lost money instead. Alth...
