Submerged descending system for deep water aquaculture facility

Abstract

The invention discloses a submerged descent system, in particular to a submerged descent system for deep-water aquaculture facilities. In its structure, a water depth pressure sensor detects the water depth of the aquaculture facility in real time and feeds it back to a controller. The controller obtains the aforementioned feedback signal and water depth pressure Feedback signals from sensors, position sensors, airbag pressure sensors, rodless chamber pressure sensors and rod chamber pressure sensors control the three-position three-way solenoid valve and the three-position four-way solenoid valve to switch between jobs to adjust the diving device in real time. The volume value of the second chamber, that is, to adjust the real-time ratio of the water injection volume of the second chamber to the buoyancy, so that it is equal to the set ratio (the water injection volume of the second chamber in the diving system (that is, the weight of the breeding facility) and the buoyancy of the submerged descending system when rising and falling at a constant speed at the set speed Ratio), so that the breeding facilities can achieve uniform lifting. It solves the technical problem of "realizing stable lifting of deep-water aquaculture facilities", so that deep-water aquaculture facilities can better resist wind and waves.

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
