Umbrella-type wave power generation device employing hydro-generator

Abstract

The invention belongs to the field of novel renewable energy technology and marine equipment and particularly relates to an umbrella-type wave power generation device employing a hydro-generator. The wave power generation device comprises a floating mast main body, floaters, main connecting rods, transmission devices, water inflow tanks, a main water flow channel and the hydro-generator, and is characterized in that the floaters are arranged at the periphery of the floating mast main body and are connected with the floating mast main body through the main connecting rods; the main connecting rods are connected with pistons in the water inflow tanks through the transmission devices; the floaters move up and down as the sea level changes and drive the transmission device to move to drive the pistons to push the water in the water inflow tanks to flow, the water gathers in the main water flow channel and flows through the hydro-generator to drive the hydro-generator to generate electricity. The wave power generation device can efficiently convert wave energy into electric energy by virtue of the change of the sea level with the transmission of waves, is applied to abyssal regions to provide power for offshore facilities such as marine navigation lights, meanwhile has higher reliability and is easy to mount and move.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to an umbrella-shaped wave energy generating device utilizing a water turbine. Background technique [0002] With the rapid development of the economy and the process of globalization, human activities have an increasing demand for energy. However, the total amount of traditional fossil resources, especially coal and oil, is limited, and the regeneration speed of their resources is also extremely slow. As a result, the development of green energy such as renewable energy has attracted more and more attention from governments and scientists in various countries. Among them, ocean wave energy is favored by scientists and engineers due to its huge reserves and wide distribution. At present, mainstream wave energy devices can be divided into three categories according to their deployment locations: offshore, near-shore and shore-based. In the earl...
