Wave power generation device based on linear magnetic gear motor

Abstract

The invention discloses a wave power generation device based on a linear magnetic gear motor. The wave power generation device comprises a motor stator core, a motor converter, a magnetism regulating ring, a magnetic gear low-speed moving part, an inner floating barrel and an outer floating barrel. The motor stator core is sleeved with the motor converter, the motor converter is sleeved with the magnetism regulating ring, the magnetism regulating ring is sleeved with the magnetic gear low-speed moving part, the magnetic gear low-speed moving part is sleeved with the inner floating barrel, and the inner floating barrel is sleeved with the outer floating barrel. A first air gap is formed between the motor stator core and the motor converter, a second air gap is formed between the motor converter and the magnetism regulating ring, and a third air gap is formed between the magnetism regulating ring and the magnetic gear low-speed moving part. A motor stator shaft and the magnetism regulating ring are fixed in position, and the magnetic gear low-speed moving part and the inner floating barrel are fixed in position. The wave power generation device has the advantages that no huge speeders need to be additionally arranged, the size is small, energy capture and power generation efficiency is high, and convenience is brought to design, debugging and maintenance of an electrical control system through the whole floating suspended structure.

Description

technical field [0001] The invention relates to a wave energy generating device based on a linear magnetic gear motor, which is a wave energy generating device that comprehensively utilizes a linear magnetic gear and a permanent magnet linear motor. Background technique [0002] Since the 1970s, with the decrease of biochemical energy and the aggravation of environmental pollution, people are increasingly favoring non-polluting, clean and sustainable renewable energy in terms of energy intake and application. Wave energy is an inexhaustible renewable energy. Compared with wind energy and solar energy, wave energy also has the advantages of high power density and strong predictability, and has attracted the attention of experts and scholars at home and abroad. As a large ocean country, my country has a coastline of more than 18,000 kilometers and an island coastline of 14,000 kilometers. It is rich in wave energy resources. According to estimates from China's coastal marine o...
