Decontamination device and method for pond intensive culture net cage

Abstract

A cleaning device for intensive pond culture net cages. The front end of the culture net cage is provided with a water body exchange module, and the rear end is provided with a sewage collection module. The culture net cage includes a culture tank formed under a buoyancy frame, and at least one set of The cleaning module and the wire rope transmission mechanism that can drive the cleaning module to reciprocate. The wire rope transmission mechanism includes a motor and a rotating shaft connected to the motor, and also includes at least two groups of wire rope assemblies that can be driven. Each wire rope assembly includes a suspension rail, a wire rope and The pay-off reel, the take-up reel, and the cleaning module include multiple sets of swingable brushes hinged on a beam, each brush is equipped with a counterweight, and the beam is connected to a steel wire rope that can be connected to each hanging rail The lanyard and the transmission wire rope drive the cleaning module to move back and forth in the breeding tank to clean the bottom of the breeding tank. The invention can solve the problem that the sediment at the bottom of the net cage cannot be thoroughly cleaned, and effectively improves the cleaning efficiency and 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...
