Description

An automatic hoisting, raising and catching integrated device

technical field

The invention relates to the technical field of cages for breeding and fishing and equipment for breeding and working boats, in particular to an automatic lifting and fishing integrated device.

Background technique

At present, large-scale deep-sea breeding workboats and deep-sea flexible cages have become an important direction for fishery development. At present, the large-scale deep-sea net cages are mainly focused on the large-frame welded floating-sinking net cages. The characteristics of this type of net cages are:

1) Good rigidity, able to resist strong typhoons in the deep sea. When encountering super typhoons, it can sink below the sea surface to reduce the impact of waves on the cages;

2) The scale is large, and super large cages can be made. The aquaculture waters can be changed flexibly, and can be moved to suitable aquaculture waters according to the quality of the water. However, if the cage culture is too concentrated, the disease will cause a chain reaction, which will often lead to the death of the fish in the entire cage. Regular replacement of the cage and the administration of drugs have become the main way to prevent fish damage. Because of the large size and the large number of fish, Lifting fish and changing boxes has become a "bottleneck" for the development of large deep-sea cages.

Farming workboats are another large-scale deep-sea farming method that has emerged in recent years. With the decreasing space of nearshore mariculture and the deterioration of the environment, the expansion of mariculture from nearshore to offshore has become an inevitable choice for the sustainable development of mariculture in my country. The farming boat is equivalent to a super-large floating cage, and the fish farming boat can go deep into the deep sea area that ordinary farming cages cannot reach. The cold-water group breeding workboat can pump low-temperature seawater in the ocean cold water group through circulation, and can carry out high-value marine cold-water fish farming such as salmon at low cost. A farming ship is composed of multiple cages. In order to reduce diseases, the fish need to be replaced regularly, and changing the cages is also a heavy work.
