Gravity pendulum wave power generation device

Abstract

The invention belongs to the field of novel renewable energy technologies and marine equipment and particularly relates to a gravity pendulum wave power generation device. The device comprises a power generation chamber, a pendulum plate, standing columns, fixed pulleys, a wire rope, a rotating shaft and an electromagnetic power generation device, and is characterized in that the whole device is placed on a seafloor foundation via the standing columns; the power generation chamber is mounted above the standing columns; the electromagnetic power generation device is mounted in the power generation chamber; the rotating shaft and the pendulum plate are arranged between the two standing columns; the rotating shaft is fixed on the bottom plate of the power generation chamber; and the pendulum plate is connected with the electromagnetic power generation device via the wire rope and the fixed pulleys. The device designed by the invention can efficiently converts wave energy into electric energy by utilizing the water flowing speed change with wave transmission, is applied to offshore areas to provide power for offshore facilities such as marine navigation lights and observation stations, is easy for direct power generation networking, meanwhile has higher reliability and is convenient to manufacture and mount.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to a gravity pendulum type wave energy generating device. Background technique [0002] With the development of the world economy, the increase of population, and the continuous improvement of social living standards, the demand for energy in various countries is growing rapidly. In recent years, driven by the depletion of fossil energy, energy supply security, and environmental protection, ocean energy, one of the major renewable energy sources, has made great progress, and ocean energy application technologies have become increasingly mature, providing human beings with the opportunity to make full use of ocean energy in the 21st century. A bright future is shown. [0003] At present, the main wave energy devices in the world can be divided into three categories according to their location distribution: offshore type (more than 2.5Km offshore)...
