Electromagnetic wind-induced galloping energy collection device

Abstract

The invention discloses an electromagnetic wind-induced galloping energy collection device which comprises a main frame, an elastic vibration beam, a coil, a permanent magnet, a choked flow vibrator and an amplitude limiting assembly. One end of the elastic vibrating beam is fixed on the main frame, and the other end of the elastic vibrating beam is fixedly provided with a choked flow vibrator; wherein the plane where the elastic vibration beam is located is arranged in the vertical direction, and the length direction of the flow choking vibrator is arranged in the vertical direction; the coil is fixed on the main frame, the permanent magnet is fixed at the end part of the choked flow vibrator, and the coil and the permanent magnet are opposite to each other but not in contact with each other; the two amplitude limiting assemblies are installed on the main frame and located on the two sides of the flow blocking vibrator respectively, and the amplitude limiting assemblies are used for limiting the amplitude of the flow blocking vibrator when the flow blocking vibrator does left-right reciprocating periodic motion. According to the invention, the problems of large internal impedance (megohm level), low energy conversion efficiency and small output power of a piezoelectric wind-induced vibration energy harvesting structure can be solved.

Description

Technical field

[0001] The present invention belongs to the field of electrical technology, specifically relates to an electromagnetic wind-induced vibration energy harvesting device. Background

[0002] With the rapid development of modern information technology, the demand for information and timeliness put forward higher and higher requirements, in order to meet the needs of information collection, the distribution and application of wireless sensor networks have become more and more extensive. The question that arises is how to provide effective and stable long-term power supply to these wireless sensing networks. Traditional chemical batteries have limited use time due to their storage capacity limitations and must be replaced regularly, unable to meet the current needs of "setting and forgetting". In view of this problem, the commonly used solution is to collect and utilize the energy in the environment through different energy conversion methods, of which wind energy, as ...
