AI Technical Summary

Technical Problem

The cleaning brushes on existing aquaculture cages are prone to accumulating dirt and are difficult to disassemble, and they lack a retrieval function, which affects the cleaning effect and the operation of selling aquatic products.

Method used

An aquaculture cage comprising a self-cleaning component and a retrieval-assisted cleaning component was designed. The self-cleaning component achieves automatic cleaning through the cooperation of a supporting float, a rotating shaft, a motor housing, a connecting plate, a chute, a traction plate, a movable plate, and brush bristles. The retrieval-assisted component achieves aquatic product retrieval through a supporting frame, a movable frame, and a retrieval net.

Benefits of technology

It achieves automated cage cleaning, avoids the growth of dirt on brush bristles, improves cleaning effect, and has the function of harvesting aquatic products, ensuring the hygiene of the aquaculture environment and ease of operation.

Abstract

The utility model discloses an aquaculture net cage, including top frame and bottom frame, the upper end left and right parts fixed mounting of top frame has self -cleaning subassembly, the inner wall fixed mounting of top frame and bottom frame has salvage auxiliary cleaning subassembly. The utility model discloses through self -cleaning subassembly can automatically clean the mesh of net cage, is favorable to the sanitation of aquaculture environment. Moreover, the movable plate is detachable, and it is convenient to replace or clean the brush hair, solve the problem that the brush hair is easy to breed dirt in water and is inconvenient to detach, avoid reducing the cleaning effect after long -term use. Through salvage auxiliary cleaning subassembly can carry out salvage operation when needing to sell a part of aquatic products. Moreover, when moving frame is elevating, the brush hair rotates around the mesh and cleans, and the outer wall of moving frame is attached to the inner wall of the mesh, and it cooperates with the brush hair to make the mesh cleaner.
