Pump pressure type method of sinking floating net cage and control device

Abstract

A pumping method and equipment for controlling the sinking or floating of mash case features that the main floating pipe of mesh case has the air and water inlets and outlets, which are connected via the flexible air tubes and water tubes to the submerged pump and inflating pump respectively and the sinking-floating control box of a remote sinking-floating controller for mesh case has the buoy or floating ball at its bottom, the automatic control circuit, inflating pump and electromagnetic valves for connecting said flexible air and water tubes. When a remote sinking or floating instruction is sent to said control box in wireless mode, the water or air is filled in said main floating pipe for sinking or floating the mesh case.

Description

technical field [0001] The invention belongs to the technical field of seawater net cage culture, and in particular relates to a method and a control device for pumping net cage ups and downs. Background technique [0002] In recent years, my country's deep-sea cage aquaculture industry has achieved rapid development in China with the implementation of the national industrial structure adjustment-reduction of ships and conversion of production policies. In just a few years, my country's large-scale deep-sea anti-wind and wave net cages have been upgraded from simple introduction to independent development and industrial production. The product has been reduced by 1 / 2 to 2 / 3, some cage products have entered the international market, and a number of large-scale cage culture test demonstration bases have been established. Deep sea cage culture is gradually developing into a new high-tech industrialization industry. industry. According to preliminary statistics, my country has d...
