Problems solved by technology

In order to reduce the volume of the device, the rated pressure of the hydraulic system is set very high, and the design conditions of the unit are mainly aimed at ocean energy when the energy intensity is high. Therefore, the current marine hydrokinetic energy integrated power generation system is only suitable for oceans with high energy. Fluid kinetic energy power generation, for weak ocean fluid kinetic energy, due to low power density, low converted mechanical energy or pressure, often cannot drive the hydraulic transmission mechanism, even if the unit can start, its power generation efficiency is very low

Abstract

The invention discloses a marine fluid kinetic energy integrated generating system, which comprises energy capturing devices converting fluid kinetic energy into mechanical energy, a mechanical energy transmission mechanism and a generating mechanism converting the mechanical energy into electrical energy. The system is connected with a pressure increasing valve. The flow at an inlet of the pressure increasing valve is controlled by a switch valve. The hydraulic branch circuit is a hydraulic branch circuit group formed in a mode that at least more than two hydraulic branch circuits are connected in parallel. Each hydraulic branch circuit is connected with one energy capturing device. The marine fluid kinetic energy integrated generating system adopting the structure not only can capture high-energy marine fluid kinetic energy, but also can capture weak marine fluid kinetic energy and is particularly suitable for the integrated generating system for capturing the weak marine fluid kinetic energy.

Description

technical field [0001] The invention relates to the technical field of power generation systems, in particular to a hydraulic transmission-based marine fluid kinetic energy comprehensive power generation system. Background technique [0002] As the excessive use of fossil resources is on the verge of depletion and the environmental problems caused by it are becoming more and more serious, ocean energy as a renewable energy has been paid attention to by the whole world. Ocean hydrodynamic energy mainly refers to ocean current energy and wave energy, and there are many forms of power generation devices. , but its basic structure generally includes the following three parts: 1. Energy capture device that converts fluid kinetic energy into mechanical energy; 2. Transmission mechanism; 3. Power generation mechanism that converts mechanical energy into electrical energy. The wave energy is converted into hydraulic energy, and the ocean current energy capture mechanism is connected...
