Wave power generation system based on tubular type permanent-magnet linear generator

Abstract

The invention relates to the technical field of sea wave power generation and linear movement power generation, in particular to a wave power generation system based on a tubular type permanent-magnet linear generator. The wave power generation system based on the tubular type permanent-magnet linear generator comprises a main panel and generator modules, wherein a plurality of motor grooves are formed in the main panel; the generator modules are inlaid in the motor grooves; each generator module comprises a primary stator, a secondary rotator and a central shaft; each primary stator is arranged on the inner wall of the corresponding motor groove; each central shaft is arranged in the center of the corresponding motor groove; each secondary rotor takes the corresponding central shaft as an axis and flows through the corresponding motor groove along with wave so as to drive the corresponding primary stator to move in the front-back direction in a reciprocating manner; and wave energy is converted into electric energy. The main panel is separated from the generator modules, design debugging and repair and maintenance in the future of an electrical control system are facilitated greatly, the power generation system is optimized, wave energy can be absorbed well, and the economic effect is good.

Description

technical field [0001] The invention relates to the technical fields of ocean wave power generation and linear motion power generation, in particular to a wave energy power generation system based on a cylindrical permanent magnet linear generator. Background technique [0002] With the development of science and technology and the acceleration of the modernization process, human beings' demand for energy will increase, resulting in a serious consumption of primary energy, especially the depletion of resources such as oil and natural gas, and also causing serious environmental pollution. , so people have to look for non-polluting, clean and sustainable renewable energy to solve the current crisis. Ocean energy includes ocean wind energy, tidal energy, wave energy, ocean biomass energy, ocean temperature difference energy, ocean salinity energy and ocean current energy, etc. Wave energy is one of ocean energy. Compared with wind energy and solar energy, wave energy has The ad...

AI Technical Summary

Problems solved by technology

[0003] After decades of research, domestic and foreign scholars have proposed a variety of wave energy conversion technologies, but there has been no revolutionary breakthrough in the use of wave energy for power generation.

In the past systems that use wave energy to generate electricity, various mechanical or hydraulic devices are used to convert the up and down reciprocating linear motion of waves into rotary motion, so that the rotating motor is used to convert energy, which will inevitably lead to energy loss during the conversion process. , at the same time, the rotating motor has the problems of low efficiency and poor durability under the condition of low speed, which seriously restricts the development of wave power generation technology

If a traditional gearbox or hydraulic system is used to increase the speed of the engine to increase the speed of the engine mover, it will inevitably lead to problems such as reduced overall system efficiency and complicated maintenance.
