Buoyancy regulating device

Abstract

The invention relates to a buoyancy regulating device belonging to a hydraulic device and being used for marine monitoring and marine exploration and solving the problems of large mass, volume and power consumption of the traditional buoyancy regulating device. In the invention, an oil tank is respectively connected with a first reversing valve, a hydraulic pump and a third reversing valve through pipelines; the hydraulic pump is sequentially connected with a second reversing valve, a one-way valve and an oil pocket inlet; the third reversing valve is connected with an oil pocket outlet through a throttling valve; and a liquid pressure sensor, a gas pressure sensor and a temperature sensor respectively arranged on the oil tank and an oil pocket are respectively connected with a control circuit through electric signals, the control circuit is respectively used for outputting control signals to the first reversing valve, the second reversing valve and the third reversing valve and a motor controller, and a direct-current motor is controlled by the motor controller to drive the hydraulic pump. The invention has the advantages of simple structure, small volume, light weight, reliable motion and low power consumption, wherein the buoyancy change range is 0-50N, the maximum submergence depth reaches 1800m, the power consumption is lower than 250W, and the mass is less than 25kg.

Description

technical field [0001] The invention belongs to a hydraulic device, in particular to a buoyancy regulating device, which is used for ocean monitoring and ocean exploration. Background technique [0002] Ocean monitoring is the basis for ocean research, development and utilization. Ocean observation instruments and ocean measurement platforms are tools and means for ocean observation, and are the foundation of ocean undertakings. Having advanced automatic marine observation instruments and reliable data acquisition systems is one of the necessary prerequisites for my country to become a marine power. In marine environment monitoring and resource investigation, long-term, fixed-point, real-time, and three-dimensional monitoring of the marine dynamic environment is often required, that is, the measurement of different profile parameters (such as temperature, salinity, flow velocity, and optical characteristic quantities) in the ocean water body. The traditional marine fixed-po...
