A kind of double-layer breeding seine net with cleaning device

Abstract

The invention provides a double-layer aquaculture seine net with a cleaning device, which belongs to the technical field of aquaculture seine equipment. The present invention comprises a plurality of purse seine components which are close to each other in turn. The purse seine component comprises an upper fixed block, a fixed seat, four first rotating shafts, a net, a rolling mechanism and a first cleaning mechanism. The upper fixed block is rectangular and has four The corners are all provided with rounded corners, the shape of the fixed seat and the upper fixed block are consistent, and the four first rotating shafts are vertically rotated and arranged between the upper fixed block and the fixed seat, and the first rotating shafts are located at the corresponding rounded corners. Located on the outside of the four first rotating shafts, an intermediate cavity is formed between the net and the fixed seat. The net is rotated between the upper fixed block and the fixed seat through the first rotating structure and the second rotating structure, and the rolling mechanism can drive The net rotates around the middle cavity, and when the net rotates, the first cleaning mechanism can clean the outer side of the net. The invention can clean the inner and outer sides of the net clothes, improve the cleaning efficiency, and prevent fish schools from escaping from the seine net.

Description

technical field [0001] The invention belongs to the technical field of aquaculture purse, and relates to a double-layer aquaculture purse with a cleaning device. Background technique [0002] The seine breeding project refers to the use of nets, piles, floating balls (floating ropes, floating frames, suspension cables) and other engineering facilities to enclose a certain scale of waters in oceans, lakes, reservoirs or river waters. The selection has important economic value. It is an ecosystem-based aquaculture model to stock fish and implement controlled feed feeding. [0003] Due to the large space, natural environment and high quality of aquaculture products, large-scale seine aquaculture has gradually become a new model and main force of high-end marine aquaculture. [0004] Since the net of the seine is submerged in water for a long time, it is easy to grow various attached organisms, block the mesh, and affect the water exchange inside and outside the seine. The exis...

AI Technical Summary

Problems solved by technology

[0004] Since the net of the seine is submerged in water for a long time, it is easy to grow various attached organisms, block the mesh, and affect the water exchange inside and outside the seine. The existing cleaning equipment can only clean one side of the net, and the cleaning effect is poor.

[0005] In addition, the currently commonly used seine netting is only a single layer. Due to the large area of ​​the seine net, if the net is damaged, it cannot be found and repaired in time. Over time, a large number of fish will escape from the seine net, reducing Farming output
