Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a coil structure applied to a bladeless wind power generator. Background Art

[0002] Traditional blade-type wind turbines convert the rotational mechanical energy of blades into electrical energy through electromagnetic induction. They have high requirements for wind speed and are usually placed in coastal areas, offshore areas and other high-wind areas in order to obtain higher and more stable wind speeds and ultimately convert the kinetic energy of wind into electrical energy. One way to generate electricity from bladeless wind power is to use an electromagnetic wind vibration energy harvesting device to utilize the vortex-induced vibration generated by the fluid in the natural wind field passing through the circular cross-section bluff body, and then convert the wind energy into mechanical energy through a mechanical vibration structure and an electromagnetic conversion structure, and then convert the mechanical energy into electrical energy.

[0003] At present, the power generation part of the traditional bladeless wind turbine is usually designed in the form of inner and outer magnetic rings. Through the arrangement of the inner and outer magnetic rings, and the coil between the two, when the inner and outer magnetic rings move relative to each other, magnetic flux lines are cut, thereby generating electricity. Although the bladeless wind turbine designed in this way can achieve the power generation effect, its structure is generally more complicated, and the component settings are relatively fixed. After a set of structures are designed, it is difficult to make changes on the original basis. It is necessary to redesign a set of devices that meet the requirements, which greatly wastes materials and increases costs. In addition, the existing coil distribution method is to distribute in the same plane as the inner and outer magnetic rings, or part of the structure is distributed in the same plane, which will cause the cross-section of the entire power generation device to become larger, which is not conducive to transportation and installation, and also increases the overall material cost.

[0004] In view of this, how to overcome the defects of the prior art and how to solve the problems that the existing bladeless wind turbines are not conducive to transportation and installation and the material cost increases are difficult problems that need to be solved urgently in this technical field.
