Description

Automatic cleaning device for offshore cage

Technical Field

The utility model relates to an industrial aquaculture field of aquatic products, especially an automatic belt cleaning device of marine cage.

Background

The raft culture of shellfish has the advantages of convenient management, low cost, high yield, high growth speed and the like, and is widely applied in China. The raft culture suspension cage for the shellfish comprises a long cylindrical net coat, a plurality of partition plates arranged in the net coat at equal intervals and a down-decorated heavy object, wherein the net coat is connected with the edges of the partition plates through fish wires; when scallops are cultured, the scallops are required to be placed on the rubber partition plates respectively, then openings of the net are sewn, a certain number of scallops are arranged in each partition layer respectively, and after the scallops grow up in the sea, the scallop culture suspension cage is required to be fished from the sea, and the scallops are taken out; in the culture process, the suspension cage is soaked in water for a long time, so that attachments such as filamentous algae and the like on the suspension cage can rapidly grow, the attachments are attached to the net to block meshes, and the attachments compete with shellfish for bait, so that the shellfish die due to oxygen deficiency. And the attachments can increase the weight of the suspension cage and influence the wind and wave resistance of the floating raft. If the cleaning is not performed in time, during harvesting, the fished scallop cultivation cage can adsorb a plurality of other shellfish and algae, the adhesion between the shells and the scallop cultivation cage is very dense and firm, and the shells and the algae are difficult to separate from the scallop cultivation cage manually; the traditional cage cleaning method has the defects that interval time is long, scallop growth is influenced, steps are multiple, time is consumed for a long time, labor cost is high, bacteria breeding is caused, odor is bad, and the effect of removing pollution seriously is poor. In addition, a net scraper method is used for preventing attachment of attachments, and the net scraper sleeved on the cage can move up and down on the cage by utilizing waves generated by tides, so that attachment of dirty objects is avoided. The prevention and treatment method has the disadvantages of non-ideal cleaning effect, large environmental influence, multiple uncertain factors and low intelligent degree.

There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
