A self-adaptive dynamic pressure compensation system for deep sea current energy hydraulic turbine power generation

Abstract

The invention discloses a self-adaptive dynamic pressure compensation system for hydraulic power generation of a deep-sea current-energy water turbine. The energy-harvesting subsystem of the sea-current-energy water turbine is used to efficiently capture the low-velocity current energy of the deep sea to obtain sea kinetic energy to realize the hydraulic control of the hydraulic pump of the control subsystem. The rotation of the output shaft generates the pressure of the hydraulic system. The electromagnetic reversing control subsystem realizes the transformation of pressure and flow in different directions. The external pressure compensation subsystem realizes the pressure balance compensation between the deep sea seawater pressure and the hydraulic system. The subsystem supplies power, and the power generation subsystem also provides electrical signals to the electromagnetic commutation control subsystem to realize direction switching. The invention realizes the rotation of the water turbine by utilizing the low-speed ocean current in the deep sea. The water turbine drives the hydraulic pump control subsystem to generate hydraulic system pressure. The pressure of the hydraulic system realizes deep-sea high pressure compensation through the external self-adaptive dynamic pressure compensation subsystem, and the hydraulic system drives the generator to generate electricity.

Description

technical field [0001] The invention belongs to the technical field of pressure compensation, and in particular relates to an adaptive dynamic pressure compensation system for hydraulic power generation of a deep sea current energy water turbine. Background technique [0002] The world's conventional energy is facing a crisis of depletion. As a new energy, ocean energy is a new energy that needs to be developed and utilized urgently and has strategic significance. Ocean energy reserves are very large, and theoretically it can partially or fully meet the energy needs of people all over the world: the current global ocean energy reserves are initially estimated to be as high as 150 billion kilowatts. As a renewable energy with high energy density, ocean current energy has high stability and high predictability, and has attracted more and more attention from countries and regions with energy demand. [0003] Due to the low flow rate of current energy in the deep sea and the hi...

Problems solved by technology

The problem of power supply for deep-sea equipment such as deep-sea vehicles, deep-sea operating robots, and deep-sea monitoring networks is becoming more and more prominent. At present, only battery charging or chemical energy power generation is used to provide power, which has the disadvantages of being unsustainable and damaging the environment. And the scale is far from meeting the needs of large deep-sea power consumers
