Hydraulic power generation self-adaptive dynamic pressure compensation system of deep sea ocean current energy water turbine

Abstract

The invention discloses a hydraulic power generation self-adaptive dynamic pressure compensation system of a deep sea ocean current energy water turbine. An ocean current energy water turbine energy capturing subsystem is adopted to efficiently capture deep sea low-flow-speed ocean current energy to obtain ocean current kinetic energy so as to realize rotation of a hydraulic pump output shaft of a hydraulic control subsystem to generate hydraulic system pressure; an electromagnetic reversing control subsystem realizes pressure flow conversion in different directions, an external pressure compensation subsystem realizes pressure balance compensation between deep sea water pressure and a hydraulic system, a hydraulic motor subsystem drives a power generation subsystem to supply power to a load subsystem, and the power generation subsystem also provides an electric signal to the electromagnetic reversing control subsystem so as to realize direction conversion. According to the hydraulic power generation self-adaptive dynamic pressure compensation system of the deep sea ocean current energy water turbine, rotation of the water turbine can be achieved through a deep-sea low-flow-speed ocean current, the water turbine drives the hydraulic pump control subsystem to generate the hydraulic system pressure, deep-sea high-pressure compensation of the hydraulic system pressure is achieved through the external self-adaptive dynamic pressure compensation subsystem, and the hydraulic system drives a power generator to generate the power.

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
