Problems solved by technology

Electromagnetic conversion mainly uses the principle of electromagnetic induction, but there are disadvantages such as large volume. Electrostatic conversion uses electrostatic effects, and generally needs to be connected to an external power supply separately as a starting voltage, so it cannot solve the above problems

Embodiment Construction

[0028] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0029] A breeze energy harvesting device adapted to low wind speed and multiple wind directions, such as Figure 1 to Figure 4 As shown, it includes a windmill, a barrel, a concave part and a cantilever beam, and a piezoelectric sheet is pasted on the cantilever beam; the windmill is rotatably connected with a barrel, and the barrel passes its stored elastic potential energy through the concave The component causes the cantilever beam to vibrate, which in turn deforms the piezoelectric sheet and generates electricity.

[0030] One end of the windmill is coaxially fixed with a first fixed shaft, and the other end of the first fixed shaft is vertically fixed on the second fixed shaft; a first gear is coaxially sleeved on the first fixed shaft, and the second A second gear is coaxially sleeved on the fixed shaft, and the first gear and the second gea...

Abstract

The invention relates to a breeze energy collecting device suitable for low wind speed and multiple wind directions, and the device is technically characterized in that the device comprises a windmill, a spring box, a concave part and a cantilever beam, wherein a piezoelectric plate is adhered to the cantilever beam; the windmill is rotationally connected with a spring box, the spring box enables elastic potential energy stored in the spring box to cause vibration of the cantilever beam through a concave part, and then the piezoelectric plate deforms to generate electric energy. Aiming at the condition that more and more wireless sensors are distributed on wind power plants, transformer substations and power transmission lines which are sparsely populated or complex in environment, the problems of electric energy supply and energy management of massive sensors can be effectively solved, and one-time deployment and long-term use can be basically realized.

Description

technical field [0001] The invention belongs to the technical field of grid auxiliary equipment, and relates to a breeze energy collection device, in particular to a breeze energy collection device adapted to low wind speed and multiple wind directions. Background technique [0002] In order to speed up the construction of ubiquitous power Internet of Things, the State Grid Internet Department, together with relevant departments, provincial (municipal) companies, and scientific research and industrial units, proposed the "Overall Plan for Ubiquitous Power Internet of Things Construction" in March 2019. Utilize the ubiquitous power Internet of Things to improve the operation efficiency of the power grid system from four aspects: holographic perception, ubiquitous connection, open sharing, and business innovation. In order to meet the needs of power grid data collection, more and more wireless sensors are distributed in wind farms, substations and transmission lines with spars...
