Wave energy and ocean current energy integrated generator and power generation method thereof

Abstract

The invention provides a wave energy and ocean current energy integrated generator comprising an undersea guide caisson, a water turbine, a vibrating floater, a round void compartment, a fixing rack, a hydraulic integrated generating module, and three hydraulic cylinders. The water turbine is disposed in the undersea guide caisson. The vibrating floater disposed outside a transmission shaft of the water turbine floats on the water surface. The round void compartment is mounted on the transmission shaft and arranged above the vibrating floater. The fixing rack is arranged on the outer surface of the round void compartment. The hydraulic integrated generating module is disposed in the fixing rack. The hydraulic cylinders are disposed between the vibrating floater and the fixing rack and convert ocean current energy and wave energy from sea water into electric energy through the water turbine and the vibrating floater, respectively. The wave energy and ocean current energy integrated generator is capable of extracting wave energy and ocean current energy at the same time, the generating process is continual and controllable, the generator is high in operational reliability, output electricity quality is high, and economic efficiency is good; in addition, the invention further provides a power generation method using the wave energy and ocean current energy integrated generator.

Description

technical field [0001] The invention relates to the technical field of marine energy development and utilization, in particular to an integrated power generation device for wave energy and ocean current energy and a power generation method thereof. Background technique [0002] Ocean energy reserves are huge, and wave energy is widely distributed, which is the focus of ocean energy development. However, although wave energy has huge reserves, it also has the characteristics of low energy density and difficult extraction, which often requires relatively large extraction equipment, and due to the harsh marine environment, the cost of offshore engineering structures is relatively high. At present, there are many technologies for the single development of wave energy, but because these development technologies need to build special support systems, the cost and maintenance costs are too high, so it is difficult to promote. The main problems that restrict the development of wave...

AI Technical Summary

Problems solved by technology

However, although wave energy has huge reserves, it also has the characteristics of low energy density and difficult extraction, which often requires relatively large extraction equipment, and due to the harsh marine environment, the cost of offshore engineering structures is relatively high

At present, there are many technologies for the single development of wave energy, but because these development technologies need to build special support systems, the cost and maintenance costs are too high, so it is difficult to promote

The main problems that restrict the development of wave energy at this stage are: single energy form, strong intermittent; uncontrollable power generation process, poor output power quality; large one-time investment for extraction devices; Great influence, etc.
