Description

Ecological aquaculture net case based on ocean pasture Technical Field The invention relates to the technical field of fishery cultivation, in particular to an ecological cultivation net cage based on a marine pasture. Background Cage culture is widely used in the world as an important production mode of marine fishery. With the expansion of the cultivation scale and the extension of the cultivation period, the problem of biological adhesion on the surface of the cultivation netting is increasingly remarkable. The sea creatures such as barnacles, oysters and algae are adhered to the aquaculture net in a large quantity, so that meshes can be blocked, water body exchange is hindered, the content of dissolved oxygen in the net cage is reduced, metabolic waste is accumulated, the weight and resistance of the aquaculture net can be obviously increased, the structural safety of the net cage is influenced, and even serious economic losses such as damage of the aquaculture net, escape of fish shoal and the like can be possibly caused due to overlarge local stress. In recent years, an underwater aquaculture net cleaning robot gradually becomes a mainstream technology for cleaning a net cage, and the robot is usually driven by a crawler belt or a back negative pressure structure to crawl or suspend on the surface of the aquaculture net, and uses a rotary brush disc and high-pressure water jet to clean attachments; However, in practical application, the aquaculture net is always in a dynamic deformation state under water and is influenced by multiple hydraulic factors such as ocean currents, tides, waves and the like, so that irregular swing and local concave deformation of the aquaculture net can be generated. When the aquaculture net cleaning robot works on such dynamic surfaces, the relative positions of the robot and the aquaculture net are difficult to accurately maintain, and due to elastic deformation and dynamic swing of the aquaculture net, the contact pressure between the robot brush head and the surface of the aquaculture net is large and small, the aquaculture net material can be damaged when the pressure is too large, and hard shell attachments cannot be effectively removed when the pressure is too small.
