Novel multi-buoy direct-driven type wave power generation device

Abstract

The invention discloses a novel multi-buoy direct-driven type wave power generation device, and belongs to the field of wave energy acquisition. The wave energy can be efficiently converted into the electric energy. The novel multi-buoy direct-driven type wave power generation device has the advantages of being simple in structure, convenient to install and repair and environmentally friendly, canadapt to various wave heights and the wave periods, and achieves the quite high energy conversion efficiency. The novel multi-buoy direct-driven type wave power generation device comprises multiple buoys, Halbach permanent magnet linear generators, linear sliding rails and sliding wheels. The end faces of the multiple buoys are connected to be linear through the linear sliding rails and the sliding wheels. The primary pole and the secondary pole of each Halbach permanent magnet linear generator are installed on the adjacent end faces of the two corresponding buoys correspondingly. Acceleration sensors are installed on the surface of each buoy, and a signal acquisition and processing system, a buoy length control system, an electric energy control and storage device and a cable are installed inside each buoy. The acceleration sensors are connected with the signal acquisition and processing systems, the buoy length control systems and the electric energy control and storage devices. Theprimary poles of the Halbach permanent magnet linear generators are connected with the electric energy control and storage devices and the cables.

Description

technical field [0001] The invention belongs to the field of wave energy collection, in particular to a novel multi-pontoon direct-drive wave energy generating device. Background technique [0002] At present, the energy consumed by human beings is still dominated by traditional fossil energy such as oil, coal, and natural gas, but no amount of non-renewable energy will be exhausted one day. With the development of economy and society, the demand for energy is increasing, which accelerates the consumption of energy, and the development and utilization of renewable clean energy is imminent. In recent years, the development and utilization of wind energy, solar energy and other energy sources have a good momentum, but the development and utilization of ocean wave energy with extremely rich reserves and high energy density is still relatively lagging behind, and more research and development efforts are needed. [0003] Traditional wave power generation devices, such as noddin...

AI Technical Summary

Problems solved by technology

However, unconstrained issues such as mooring, seawater corrosion, maintenance channels, and long underwater cables are bottlenecks in the development of direct-drive wave energy harvesting devices

At the same time, linear generators also have some internal disadvantages, including large size, significant end effects, high cogging forces, high cost and efficiency limitations
