Background technique

China's aquaculture industry is developing rapidly, and mariculture plays an important role as an important part of my country's aquaculture. In recent years, my country has vigorously promoted the sustainable development strategy, and energy conservation and emission reduction have become an important policy for the country's future development. Aquaculture has high economic benefits, but it consumes a lot of water resources. The traditional drainage device for mariculture ponds is a river gate, and drainage is realized by lifting the gate. This drainage device can selectively discharge bottom water or bottom water and surface water together according to the lifting height of the gate, thus causing waste of water resources to a certain extent. In addition, the southeastern coast of my country is affected by typhoons and tropical cyclones during the breeding season, and often experiences short-term sharp rainfall, resulting in drastic changes in the salinity of seawater in the breeding ponds. However, many mariculture objects, such as prawns, are sensitive to sharp changes in salinity. They often undergo stress reactions due to sudden changes in water salinity caused by heavy rainfall brought by typhoons, causing disease or death of cultured prawns, resulting in unnecessary losses. Therefore, it is also a very important management measure to selectively discharge surface water in mariculture ponds to maintain salinity stability in typhoon and rainy seasons.

Have again, existing pond sluice gate draining device, need someone to keep an eye on in the draining process, to prevent that water level row is many. The displacement cannot be preset, which virtually increases labor costs for aquaculture.

Chinese patent document CN201120381893.0, date of application October 10, 2011, the patent name is draining device for seedling pond, discloses a draining device for seedling pond, there is a drain at the bottom of the seedling pond, a filter cartridge is arranged on the drain, and includes The fixed suction pipe and the regulating pipe, the lower end of the fixed suction pipe is fixedly connected with the drain port and there is a suction hole on the pipe wall, the regulating pipe is fitted in the fixed suction pipe or outside the fixed suction pipe with clearance fit, and the regulating pipe is connected with a lifting control structure, adjusting The height of the pipe is less than the height of the fixed suction pipe, and the height of the fixed suction pipe is greater than the water depth in the nursery pond.
