Self-cleaning culture pond and self-cleaning method

Abstract

The invention discloses a self-cleaning culture pond and a self-cleaning method. The self-cleaning culture pond and the self-cleaning method aim to overcome the defect that dirt in the culture pond isinconvenient to clean. The self-cleaning culture pond comprises a cylindrical culture pond body, a bottom plate and a cover plate. Guide columns are installed in the culture pond body, the bottom plate and the cover plate sleeve the guide columns, the cover plate is rotatably installed on the bottom plate, the bottom plate is installed at the position, close to the lower part, in the culture pondbody in a lifting mode, and a plurality of lower through holes are formed in the bottom plate, a plurality of upper through holes corresponding to the lower through holes one to one are formed in thecover plate, air bags installed on the lower surface of the bottom plate and connected with an inflation and deflation pipe, and a drain outlet is formed in the bottom of the culture pond body. The air bags are inflated, the air bags bulge to increase buoyancy to jack up the bottom plate, when the air bags rise to the position close to the upper part of the culture pond body, the cover plate rotates to enable the upper through holes and the lower through holes to be staggered, and the cover plate covers the lower through holes; and the air bags are deflated and contracted, the bottom plate and the cover plate sink under the action of gravity, and the cover plate rotates reversely to enable the upper through holes and the lower through holes to communicate in a one-to-one correspondence mode when the bottom plate and the cover plate sink to the position close to the initial position.

Description

technical field [0001] The invention relates to an aquaculture technology, more specifically, it relates to a self-cleaning culture pond and a self-cleaning method. Background technique [0002] my country is a big aquaculture country in the world, and its aquaculture output accounts for more than 70% of the world's total output. Among them, the use of aquaculture ponds is an important aquaculture method in aquaculture. After long-term use of the breeding pond, there will often be thick garbage accumulated at the bottom of the breeding pond, such as fish feces, dregs of feed, etc. In the long run, it is easy to make the space in the breeding pond small, and it is easy to breed bacteria and viruses , Need to clean the dirt and garbage inside frequently. At present, the dirt on the bottom of the aquaculture pond is generally cleaned manually, and even the water in the aquaculture pond needs to be drained before cleaning. Draining the water in the aquaculture pond requires cha...
