Description

Technical Field:

[0001] The utility model relates to the technical field of aquaculture, in particular to the technical field of floating water pumps for the water environment ecosystem of aquaculture, and specifically, to an oxygen-increasing floating water pump for aquaculture ponds. Background Art:

[0002] Most of the water in aquaculture is stagnant. When a large number of fish are cultured in this water, algae accumulate in the water, fish reproduce in large numbers, the water color changes sharply, and the dissolved oxygen saturation decreases. Due to the stagnant water, an oxygen-deficient phenomenon will occur in the water, which will affect the healthy growth of fish. This state will cause a large number of fish deaths. How to increase the oxygen in the water for aquaculture is a problem that needs to be solved.

[0003] In the prior art, floating water pumps are mostly used in aquaculture to increase oxygen in the pond water. A floating water pump, also known as a suspension pump, is a movable drainage and irrigation machine that is directly driven by a motor installed in an air chamber or a floating water cover, can float on the water surface and can rise and fall with the water surface. The floating water pump floats on the water surface, and the water inlet is 25-50 cm below the water surface. By spraying the aquaculture water, the aquaculture water is fully contacted with the air, increasing the oxygen content in the aquaculture water, reducing the aggregation and reproduction of algae in the water, and always keeping the water flowing can reduce the risk of fish diseases. It has a cooling and oxygen-increasing effect during the high-temperature period, improving the survival rate and growth rate of fish. And using a floating water pump is not affected by the bottom sediment. However, it has the following defects. Since the motor of the floating water pump is installed in an air chamber or a floating water cover, and the air chamber or floating water cover is mostly made of plastic material, the heat dissipation effect of the motor is poor, it is easy to burn out, the working efficiency is low, the maintenance is frequent, and the maintenance cost is high.
