Remote controlling system and method for liftable cages

Abstract

A remote control system for lifting netted case is composed of floating netted casing for culturing purpose, the main flating tube with water valve and air valve, air pump, and lifting control unit consisting of casing, solar cell board, electric accumulator, motor, air pump, electric valve and program control box. Its control method features that the floating or sinking command is transmitted from mobile telephone to mobile communication module of said system for executing lifting or sinking operation.

Description

technical field [0001] The invention belongs to the remote control technology of lifting and lowering net cages in the aquaculture technology, and specifically relates to a lifting and lowering net cage capable of remote control 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 SparTechnology 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 i...

Problems solved by technology

Therefore, both the design of its control method and the practical application have the following problems: (1) Since the submersion of the net cage is realized through the water intake and exhaust in the floating tube, sometimes there will be problems during the submersion process. Water resistance phenomenon, that is, the gas in a certain section of floating pipe or air pipe is sealed by water, resulting in poor exhaust, the floating pipe cannot be completely filled with water, and the cage cannot continue to dive; (2) The water and air valves are not sealed Protection measures and automatic monitoring function, so when the cage does not need to dive, if the water and air valves leak, the floating pipe will enter the water, and the cage will dive by mistake. At this time, if the cage is not equipped with a cover net (3) the water and air valves of the net cage need to be manually opened and closed, so no matter what the sea conditions are, it is necessary to send people to the net cage by boat to open the valve and complete the process. Cage dive operation

Therefore, it is urgent to solve the anti-wind and wave technology of the net cage, improve the overall ability of the net cage to resist strong winds and large waves, so as to avoid the economic loss caused by the damage of the net cage and the fish escaping from the broken net
