Dirt cleaning device and method for pond intensive culture net cage

Abstract

A dirt cleaning device of a pond intensive culture net cage is characterized in that a water body exchange module is arranged at the front end of the culture net cage, a dirt collection module is arranged at the rear end of the culture net cage, and the culture net cage comprises a culture tank formed below a buoyancy frame and provided with at least one group of sweeping modules and a steel wirerope transmission mechanism capable of driving the sweeping modules to reciprocate; the steel wire rope transmission mechanism comprises a motor and a rotating shaft connected with the motor, and further comprises at least two groups of steel wire rope assemblies capable of transmission, each steel wire rope assembly comprises a hanger rail, a steel wire rope, a pay-off reel and a take-up reel, each sweeping module comprises a plurality of groups of brushes capable of swinging and hinged to a cross beam, and balancing weights are assembled on the brushes; and hanging ropes capable of being connected to the steel wire ropes in the overhead rails respectively are connected to the cross beam, and the driving steel wire ropes drive the sweeping modules to move back and forth in the culture tank to sweep the bottom of the culture tank. The dirt cleaning device solves the problem that dirt sediment at the bottom of the net cage cannot be thoroughly cleaned and effectively improves the dirt cleaning efficiency and the dirt cleaning degree.

Description

technical field [0001] The invention relates to aquaculture net cage technology, in particular to a decontamination device and method for intensive pond culture net cages. Background technique [0002] Cage culture is one of the main methods of aquaculture at present. During the cage culture process, fish excrement and food residues will settle at the bottom of the cage, forming silt that is harmful to the cage and fish. Therefore, how to Cleaning up these sediments has always been a difficult problem in cage culture. [0003] At present, net cage culture usually only uses water treatment methods such as water pushers to solve the problem of dirt precipitation. For example, the patent of Chinese Patent Publication No. CN202857545U discloses a pond net cage cleaning culture system, which uses water pushers and sewage tanks. The composed sedimentation tank removes the bottom dirt. And the patent disclosure of CN205682177U discloses a flushing device for preventing pond fouli...
