Wireless sensor energy supply device on fan blade

Abstract

The invention discloses a wireless sensor energy supply device on a fan blade. The energy supply device is arranged on the fan blade and comprises a swing-type mini-type power generation system, a rectifying circuit, a filter circuit, a voltage stabilizing circuit and an energy storing device, wherein the swing-type mini-type power generation system comprises a mini-type power generator and a driving structure of the mini-type power generator, and the driving structure is composed of relative motion of a small gear installed on a rotary shaft of the mini-type power generator and a big gear wheel embedded with a pendulum bob; after mechanical energy of the relative motion of the gears is converted to electric energy by the mini-type power generator, the electric energy is supplied to the energy storing device and a sensor node arranged on the fan blade respectively through the rectifying circuit, the filter circuit and the voltage stabilizing circuit. By designing a set of swing-type mini-type power generator energy supply mechanism, the problem of supplying energy for the sensor node arranged on the fan blade is solved well.

Description

technical field [0001] The invention relates to a wireless sensor node energy supply device, in particular to a wireless sensor energy supply device on a fan blade. Background technique [0002] With the adjustment of the global energy structure, the wind energy industry has been fully developed, the wind power technology is becoming more and more mature, and the production technology of wind turbines is also increasing day by day. In order to allow the fan to be installed with as little post-maintenance as possible, each part of the fan will be foolproof under the conditions of the existing technology before leaving the factory, and various sensors will be installed at the position where the sensor can be installed. Status monitoring during work can predict and avoid unnecessary events in advance. However, it is necessary to consider the twisting of various signal lines and power lines to arrange sensor monitoring points on various rotating devices. Therefore, in the produ...
