Wave power generation system based on multi-layer magnetic-aggregation embedded cylindrical linear generator

Abstract

The invention discloses a wave power generation system based on a multi-layer magnetic-aggregation embedded cylindrical linear generator. The wave power generation system comprises a multi-layer magnetic-aggregation cylindrical linear motor, an outer buoy and an inner buoy. The multi-layer magnetic-aggregation cylindrical linear motor consists of a primary part and a secondary part; and a magneticfield air gap is formed between the primary part and secondary part. The multi-layer magnetic-aggregation cylindrical linear motor is installed in the inner buoy and is arranged at the half upper part of the inner buoy; the primary part is fixed on the inner wall of the inner buoy; and the secondary part is connected with the outer buoy rigidly. On the basis of combination of the multi-layer magnetic-aggregation cylindrical linear motor based on a magnetic-aggregation effect and the wave power generation system, defects of low wave power generation efficiency and low cost performance of the conventional linear motor are overcome effectively and the power density of the generator and the conversion efficiency of the ocean energy are improved substantially.

Description

technical field [0001] The invention relates to the technical field of renewable energy utilization, in particular to a wave power generation system based on a multilayer magnetism-concentrating embedded cylindrical linear generator. Background technique [0002] With the rapid development of the global economy, the human demand for energy consumption is bound to increase. However, most of the world's energy consumption comes from fossil fuels. As a non-renewable energy source, fossil energy has caused a series of problems during its combustion and use, such as the greenhouse effect, environmental pollution, and geological and ecological damage. Therefore, the coordinated and sustainable development of energy consumption and the environment is the common concern of all countries in the world today. The development and utilization of new renewable and clean energy can not only meet the increasing energy consumption needs of human beings, but also improve the environment and...

Problems solved by technology

[0004] In order to solve the shortcomings of low efficiency and low cost performance of power generation equipment caused by the low wave velocity near the coast of my country, the present invention proposes a wave power generation system based on a multi-layer magnetism-concentrating embedded cylindrical linear generator. The new cylindrical linear generator replaces the traditional generator, which can greatly increase the power density of power generation equipment, reduce the cost and equipment volume of wave power generation to a certain extent, and promote the development of wave power generation in the field of new energy
