“An aquaculture cage debris cleaning device and its operation method” completed by Song Zhen and others from the Fishery Ecological Environment Research Office of Heilongjiang Institute of Chinese Academy of Fishery Sciences was authorized by the national invention patent, with the authorized patent number of zl202110868469.7.
The invention relates to the field of aquaculture and is applied to the cleaning of sundries in the process of cage aquaculture. Aiming at the problem that the water quality deteriorates due to the accumulation of sundries in the process of cage breeding, and then affects the survival and quality of breeding objects, the invention provides a device and an operation method that can automatically clean the sundries in the cage. The device drives the outer gear ring, sliding seat, inner gear ring and conveyor belt through gear mechanical transmission to complete the collection of sundries. Multiple conveyor belts work at the same time to improve the collection efficiency; Driven by the cam, the sliding seat moves up and down, which can not only provide oxygen, but also use the water wave to push the debris to the vicinity of the scraper for collection. The conveyor belt fixes the spiral hole and conical teeth, ensuring the stability of nut transmission.
The application of the device can realize the automatic cleaning of the sundries in the cage culture at any time, which is conducive to maintaining the healthy water quality of the cage culture.
