Sewage sucker for bottom of aquaculture tank

Abstract

The invention belongs to the technical field of aquaculture and particularly relates to a sewage sucker for the bottom of an aquaculture tank. The sewage sucker for the bottom of the aquaculture tank comprises electric brushes, a base, a telescopic connecting rod, a water pump, a handle and a drainage pipe. The electric brushes comprise brush heads, small motors and connecting rods, the brush heads are connected with the small motors through the connecting rods, and the electric brushes are arranged in four corners of the base. A sewage suction opening is formed in the center of the base and connected with the drainage pipe. The drainage pipe is connected with the water pump. The reverse of the base is provided with the telescopic connecting rod, and the telescopic connecting rod is provided with hanging rings and the handle. The brush heads are conical brush heads. The hanging rings are circular closed hanging rings. The required length and the controlled intensity of the sewage sucker can be freely controlled, the four electric brushes can sweep dead corners difficult to clean in all directions, the brushing intensity of the sewage sucker can be automatically controlled, and the sewage sucker can continue performing cleaning when meeting with the dead corners; besides, the replaceable brush heads allow cleaning to be more targeted.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a sewage suction device at the bottom of an aquaculture pool. Background technique [0002] In high-density aquaculture, there is a large amount of sludge at the bottom of the pond, which is composed of residual bait, feces, biological corpses, pathogenic bacteria and virus particles. These sludges are nitrogen-containing organic substances, which are decomposed into ammonia nitrogen, nitrite nitrogen, hydrogen sulfide and other substances that are extremely harmful to fish and shrimp under the action of bacteria. Moreover, they are also breeding grounds for bacteria and viruses. Therefore, timely removal of sludge is a high priority for aquatic products. It is very important work in density breeding production. Most of the suction heads used in the pool bottom suction tools in the prior art are empty pipes with cracks, so that the dirt can only be sucked away by siphon, a...

AI Technical Summary

Problems solved by technology

There is no ball valve switch at both ends of the suction pipe of the existing sewage suction tool at the bottom of the pool, which makes it inconvenient to use the suction pipe when suctioning sewage at the bottom of the pool, and needs to fill the suction pipe every time, which is time-consuming and laborious, which brings great inconvenience to the sewage suction work at the bottom of the pool
