Problems solved by technology

Garrisoned military radars, underwater vehicles (UUV, ROV) and other devices consume abnormal power. my country has also proposed to build large power consumers such as deep-sea space stations and underwater charging piles. The existing power generation mode is far from meeting the demand for electricity.

Abstract

The invention discloses a double-impeller closed circuit hydraulic transmission and control ocean current energy power generation device and a control method thereof. The first impeller device and the second impeller device arranged in parallel are driven by the ocean current energy mode, and the first impeller device and the second impeller device are arranged in parallel. The output ends of the pump are respectively connected to the corresponding generator through the pump end main shaft, the variable hydraulic pump, the pump variable mechanism, the accumulator, the variable hydraulic motor and the motor end main shaft; the variable hydraulic pump, the variable hydraulic motor and the accumulator constitute a closed system. And connected with the closed-loop control system, the closed-loop control system is used to receive the pump end spindle speed, the closed-loop control system is connected to the sea current energy velocity measuring impeller device to receive the sea current energy velocity signal, and adjust the displacement of the variable hydraulic pump and the variable hydraulic motor through control. The invention utilizes inexhaustible ocean current energy to generate electricity, and can provide sustainable energy supply for remote islands, remote waters, and underwater electrical equipment such as underwater vehicles through off-grid operation.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a double-impeller closed circuit hydraulic transmission and control sea current energy power generation device and a control method thereof. Background technique [0002] Ocean current energy is the kinetic energy of seawater flow, mainly referring to the relatively stable flow in submarine channels and straits and the energy generated by regular seawater flow caused by tides. It is another ocean energy that appears in the form of kinetic energy. It is an important part of renewable energy, with its high energy density and abundant reserves, which has attracted great attention from Europe, the United States, Britain, Japan and other countries. The field is still in its infancy. [0003] At present, the power supply of remote islands can only rely on diesel generators as the main power supply, and other wind power, photovoltaic, and wave power as auxiliary. ...
