Aeration and clearing device of circular culture pond

Abstract

The invention relates to aquaculture equipment and specifically relates to an aeration and clearing device of a circular culture pond. The aeration and clearing device comprises a water pumping pipe,a water pump, a double-shaft motor and a pond bottom clearing device; the water pumping pipe communicates with the water pump; the power input end of the water pump is connected with one rotating shaft of the double-shaft motor; the pond bottom clearing device also comprises a swivel, a swivel connecting pipe and a rotary water pipe; the top end of the swivel is fixedly provided with a swivel gear, and the swivel gear is connected with the other rotating shaft of the double-shaft motor by a gear connecting assembly; the rotary water pipe also comprises a rotary center pipe, a connecting pipe and a water absorbing and clearing pipe; the end of the rotary center pipe is rotatably connected with the end of the swivel connecting pipe, and the rotary center pipe is provided with an intermittenttransmission structure; and the connecting pipe is connected between the rotary center pipe and the water absorbing and clearing pipe. By adopting the design of the aeration and clearing device, pondwater layering can be avoided, the oxygen content of pond water can be increased, and it is convenient to clear the bottom of the circular culture pond.

Description

technical field [0001] The invention relates to equipment for aquaculture, in particular to an aeration and cleaning device for circular culture ponds. Background technique [0002] The water body in the aquaculture pond is prone to stratification under various conditions such as large temperature difference between morning and evening, excessive feeding or sudden rainstorm. After the water body is stratified, it will hinder the communication between the upper and lower water bodies, and the dissolved oxygen in the upper water body cannot be transported. Into the lower water body, the bottom of the aquaculture pond is hypoxic, and when the hypoxia is severe, it is easy to cause the floating head phenomenon of the aquatic organisms; at the same time, the hypoxia is also likely to cause a large number of anaerobic bacteria and harmful bacteria to grow in the lower water body, making aquaculture The bottom of the pond becomes smelly and harmful substances increase, affecting th...

Problems solved by technology

There are two commonly used cleaning methods: one is to transfer the aquaculture aquatic organisms to another aquaculture pond, pump out the pool water, and then clean the bottom of the pond. This cleaning method is a serious waste of water resources, and the transfer of aquatic organisms The process is also very troublesome; another cleaning method is to design the culture pond as a circle, and design the bottom of the culture pond as a concave conical shape. When cleaning the culture pond, it is necessary to stir the water in the entire culture pond to form a vortex , so that the sediment at the bottom of the pond converges to the center of the breeding pond, and then the sediment that converges to the center is pumped out. Although this cleaning method is relatively simple, it requires large-scale equipment to stir the water in the entire breeding pond. Huge energy, high cost investment, and the agitation of the pool water is likely to frighten the aquatic organisms, which is not conducive to the growth of aquatic organisms
