Anti-blocking method applicable to circulation water loach breeding pond bottom drain

Abstract

The invention discloses an anti-blocking method applicable to a circulation water loach breeding pond bottom drain. The anti-blocking method comprises the steps of arranging a sewage cleaning machine in a gap of escape-proof fences of a sewage draining machine and enabling scraping teeth protruded out of the periphery of the sewage cleaning machine to be embedded with gaps of the fences of the sewage draining machine one by one; connecting a guide rod which is welded with the center of the sewage cleaning machine and straightly led to the water surface and a connection rod to a motor which is arranged at the top end of a main frame; and dragging the guide rod and the connection rod through the motor to enable the sewage cleaning machine to move up and down, automatically clean blockage substances and retain smooth water drainage and normal circulation. The anti-blocking method applicable to the circulation water loach breeding pond bottom drain is applicable to industrial circulation water breeding of small varieties comprising loach and suitable for cleaning sediments which block water drain gaps of the bottom drain; and through the method, the anti-blocking problem of the sewage draining machine in small fish circulation water breeding can be effectively solved. The method is simple; devices are convenient to mount and manage; the sewage cleaning machine and a raw sewage draining device are only required to be matched and fixed wholly; the devices are capable of automatically operating and saving labor; and the device are excellent in economy and practicability.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for preventing blockage at the bottom of a circulating cement loach culture pond. Background technique [0002] Loach (Misgurnus anguillicaudatus) belongs to Cypriniformes (Cypriniformes), Loach family (Cobitidae), is a small freshwater economic fish, the meat is tender, delicious, nutritious, rich in minerals and vitamins, known as " The reputation of "ginseng in water" is favored by consumers at home and abroad. [0003] Industrialized recirculating aquaculture is the most advanced aquaculture production mode and the symbol of the highest technical level in the world today; it has been widely used in the aquaculture of medium and large fish such as salmon trout and flounder sole. However, there are few attempts in small-scale fish farming such as loach. Recirculating loach farming is a completely new model. Compared with other species of recirculating aquacultur...

AI Technical Summary

Problems solved by technology

The individuals of cultured loach are small, so they need denser bottom row fences to prevent escape, and the gaps between dense fences are easy to be blocked, which affects the bottom discharge water and circulation efficiency
