Description

technical field

[0001] The invention belongs to the lifting and lowering remote control technology of net cages in the aquaculture technology, and specifically relates to a lifting net cage remote control system and a control method. Background technique

[0002] Utilizing the wave theory that the wave height decays proportionally with the increase of the contour of the water depth, it is an important technical measure for the net cage to resist wind and waves to sink the cage to a certain depth of water. At present, there are two types of typical large-scale lift-type net cages in the world: one is the steel structure dish-shaped net cage of Ocean Spar Technology Company in the United States. The appearance of the net cage is similar to that of a flying saucer, and the lifting and lowering of the net cage is controlled by a central column and a 5-ton balance weight, which makes the offshore installation and laying of the net cage very difficult. The other is the polyethyle...
