Problems solved by technology

Wind power generation has a long history, but currently there are few small wind energy collectors for powering radio equipment, and most of them can only collect wind energy from a specific direction, without fully considering the equipment's ability to adapt to the environment

Embodiment

[0034] The device of the present invention adopts modular installation. Firstly, the fixed base 1 is fixedly installed in the wind field, and the rotating bearing 3 is installed in the blind hole in the middle of the fixed base 1. The lower end of the rotating support rod 2 is inserted into the rotating bearing 3, and the The upper end is welded and fixed to the internal partition 6, and the circumferential wall of the internal partition 6 is welded and fixed to the inner wall of the rotating shell 4. The four pairs of cantilever beam power generation components located below the internal partition 6 are respectively installed on the inner wall of the rotating shell 4 and the rotating strut. 2 In the fixed block 27 evenly arranged in the circumferential direction, the installation of the wind speed adaptive adjustment module and the rotation-induced swing power generation module has been completed so far; 5 is welded on the top of the rotating shell 4; finally, the vertical pos...

Abstract

The invention relates to a small-scale wind power generation device and method for self-adaptive wind direction and wind speed. The device is composed of a wind direction self-adaptive adjustment module, a rotation-induced swing power generation module, a square column and a triangular prism distance control module, and a square column vertical position control module. The wind direction self-adaptive adjustment module is used to adjust the angle between the device and the wind to ensure that the steering tailgate is located on the leeward side and parallel to the wind direction. The rotation-induced swing power generation module uses the uneven rotational centrifugal force generated by the rotation of the device to drive the magnet to shake, causing the horizontally arranged piezoelectric sheets to deform and generate electrical energy. The vertical position of the square column and the distance between the square column and the triangular prism are adjusted by the signal control box according to the real-time wind speed, and the galloping or wake-induced vibration of the triangular prism is excited, causing the vertically arranged piezoelectric sheets to deform and generate electric energy to achieve the best energy capture. Effect.

Description

technical field [0001] The invention belongs to the technical field of new energy development and utilization, and in particular relates to a small wind energy generating device and method capable of adapting to wind direction and wind speed. Background technique [0002] In recent years, MEMS engineering and technology have developed rapidly. The power consumption of radio equipment including various sensors has been gradually reduced and successfully used in various fields. However, most of them require uninterrupted power supply. If traditional fossil energy is used for energy supply, it will not only intensify the The energy crisis will also cause serious pollution to the environment. Therefore, whether it can provide sustainable and renewable clean energy has become a priority for the practical use of such equipment. At present, new energy harvesting power generation technologies such as vibration energy, solar energy, thermal energy, and tidal energy have received wide...
