Diving and falling system of deep water culture facility

Abstract

The invention discloses a diving and falling system, in particular to a diving and falling system of a deep water culture facility. According to the structure of the diving and falling system of a deep water culture facility disclosed by the invention, a water depth pressure sensor is used for detecting the water depth of the culture facility in real time and feeding back the water depth to a controller; and the controller is used for obtaining a fed-back signal and fed-back signals of the water depth pressure sensor, a position sensor, an air bag pressure sensor, a rodless cavity pressure sensor and a rod cavity pressure sensor, controlling a three-position tee electromagnetic gas valve and a three-position four-way electromagnetic gas valve to perform work switching to adjust the volumevalue of a second cavity in the diving and falling device in real time, namely that the real-time ratio of the water injection quantity of the second cavity to buoyance is adjusted to be equal to a set ratio (the ratio of the water injection quantity (namely the weight of the culture facility) in the second cavity in the diving and falling system during rising and falling at a set constant speed to the buoyance), so that the culture facility can rise and fall at a constant speed. Through the adoption of the diving and falling system disclosed by the invention, the technical problem that the deep water culture facility needs to smoothly rise and fall is solved, and the deep water culture facility can conveniently resist stormy waves better.

Description

technical field [0001] The invention relates to a submerged descent system, in particular to a submerged descent system for a deep-water aquaculture facility. Background technique [0002] Deep-water aquaculture facilities refer to aquaculture facilities that can be used in relatively deep sea areas (usually the depth of sea areas is greater than 20m), and are rapidly developing aquaculture equipment in the past ten years. How to make the breeding facilities anti-wind and wave is one of the key technologies in the field of deep-sea aquaculture. According to the wave theory that the wave height decays proportionally with the increase of the gradient of the water depth, it is necessary for the deep-water aquaculture facilities to sink the aquaculture facilities to a certain depth of water layer. Important technical measures for wind and waves. [0003] Deep-water aquaculture facilities are usually raised and lowered by injecting and releasing water into the buoyancy tank (flo...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned existing submergence control systems only simply discharge compressed air through the buoyancy tank (floating pipe) to inject water or inject compressed air to drain water to change the amount of water injection. The water volume cannot be adjusted in real time, so it is impossible to accurately control the ratio of the weight of the breeding facility to the buoyancy, that is, the uniform speed cannot be achieved during the raising and lowering of the breeding facility, which affects the stability of the raising and lowering of the breeding facility
