Background
The ocean farming is an important operation mode and is an important source of high-quality protein, and in the ocean farming, one of the most labor-intensive works is the cleaning work of the net of the farming net cage. The cultivation of marine products and the replacement of netting gear are work with great labor intensity. In the marine culture, the net cages and nets are attached by shellfish and seaweed in the sea, the attachments grow faster when the temperature of the sea water is higher, and if the attachments are not cleaned in time, the meshes are blocked by the attachments, so that the seawater exchange is not smooth, and a series of problems such as oxygen deficiency are caused. Moreover, the net tools of the cultured fishes need to be replaced from small to large in the growing process. Therefore, no matter what structure type of marine net cage, after a period of cultivation, the net must be replaced, and the net is replaced and cleaned.
The weight of a set of common polyethylene netting with the circumference of 40 meters is over 200 kilograms, and if the nylon netting is adopted, the weight is close to 300 kilograms. And the weight of the net is increased more obviously after water absorption, and the weight is very inconvenient for manual operation on the sea. If the perimeter of the net cage reaches 120 meters, the net amount can reach more than five tons. In addition, the weight of the underwater falling block for shaping the netting gear is very high in the work difficulty of replacing the netting gear. The reason is that the deep water net cages made of HDPE (high density polyethylene) are mainly 40 m or 50 m in circumference, and only enterprises or companies with certain strength can select deep water net cages with larger circumferences.

According to the empirical data of the aquaculture industry, the price of a 40-meter-circumference aquaculture net cage is about 8 to 10 ten thousand yuan, the yield can only reach 10 tons, the price of a net cage with a mouth circumference of 120 meters is about 80 ten thousand, the yield can reach 500 tons, namely the price of the net cage is 10 times different, and the aquaculture amount is 50 times different. Taking the current market price as an example, the profit of each kilogram of aquaculture products is about 2.5 yuan, the aquaculture profits of 10 tons of aquaculture net cages and 500 tons of aquaculture net cages are 5 ten thousand yuan and 250 ten thousand yuan respectively, and the profit capacity is greatly different. As can be seen from the data, the growth of the cultivation equipment to a reasonable large scale is an inevitable trend! The problem of replacing netting gear of the aquaculture net cage is solved, and the method is also a very key link in the development of aquaculture equipment.
The U-shaped net cage made of HDPE materials is difficult to realize large-scale net cages because the shape of a generalized net needs to be ensured and a plurality of anchoring and positioning methods are needed to be adopted and the replacement operation of the net is more difficult.
