8. A method of self-cleaning a culture pond, for cleaning fouling of a self-cleaning culture pond according to any one of claims 1 to 7, comprising the steps of: a. the air bag is inflated through the inflation and deflation pipe, the air bag bulges outwards to increase buoyancy, the bottom plate and the cover plate are jacked upwards together, at the moment, the upper through holes and the lower through holes are communicated in a one-to-one correspondence manner, aquatic products cultured in the culture pond move upwards along with the bottom plate and the cover plate and cannot move through the upper through holes and the lower through holes, and dirt on the upper surface of the cover plate is stirred in the moving process of the aquatic products, so that the stirred dirt flows to the lower part of the bottom plate from the upper through holes and the lower through holes along with water flow; b. the bottom plate and the cover plate move upwards together to a position close to the upper part of the culture pond body, the cover plate rotates to enable the upper through hole and the lower through hole to be staggered, and the cover plate covers the lower through hole; c. the air bag is deflated through the inflation and deflation pipe, the deflation and shrinkage of the air bag reduce the buoyancy of the bottom plate, the bottom plate and the cover plate sink under the action of gravity, the blowoff valve is opened to blow off at the moment, and meanwhile, fresh water is discharged into the pond from the upper end of the culture pond; d. when the bottom plate and the cover plate sink to the initial position, the cover plate rotates reversely to enable the upper through holes to be communicated with the lower through holes in a one-to-one correspondence mode, the drain outlet continues to discharge for a period of time, after dirt below the bottom plate is completely discharged, the drain valve is closed, and fresh water is stopped being added into the culture pond.
