Intelligent automatic pollution discharge system of prawn intensive culture pond

Abstract

The invention discloses an intelligent automatic pollution discharge system of a prawn intensive culture pond. The intelligent pollution discharge system comprises a power system, a suction system, a positioning system and an oxygen aeration system. The power system comprises a water pump, a driving water pipe and a time switch, the driving water pipe is connected with the water pump, and the water pump can be driven under the control of the time switch; the suction system comprises a suction pipe connected with a central pollution discharge pipe of a pond body; the positioning system comprises a screen frame, a lifting sucker and a 360-degree turntable, the lifting sucker is arranged on the screen frame, the 360-degree turntable is connected with the screen frame, and the oxygen aeration system comprises an oxygen aeration pipe. The intelligent automatic pollution discharge system has the advantages that technical problems that an existing drain pipe is heavy, contact positions of the existing drain pipe and a drain outlet often are adhered with each other and are difficult to pull up manually after the existing drain pipe is used for a long time, labor can be wasted, pollution discharge time is difficult to accurately control, workload is high, time can be wasted and the like can be solved; an automatic pollution discharge effect can be realized by the pollution discharge system under the timed control of a servo motor, and accordingly workload can be greatly reduced; a suction range of the suction pipe can be enlarged by the aid of lifting and rotating modes, so that the problem of difficulty in discharging pollution at the bottom of an existing culture pond in culture procedures can be solved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a 360-degree rotary automatic sewage suction system and method for intensive prawn cultivation ponds. technical background [0002] The prawn aquaculture industry is the pillar industry of my country's aquaculture industry, and the aquaculture output ranks first in the world. In 2012, the prawn production in China reached 1.56 million tons, accounting for about 40% of the global prawn production. Although my country is the largest country in prawn, the prawn Although pond farming has reached the international leading level in terms of scale and output, the sustainable development of the industry still faces severe challenges. Shrimp farming has various farming modes such as intensive culture, semi-intensive culture and extensive culture. Intensive culture is a high-input, high-yield and high-risk farming method. In coastal areas, large-scale breeding enterprises and farmers all adopt thi...
