Embodiment Construction

[0014] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1-2 As shown, the magnetostrictive-based rotating piezoelectric breeze power generation device includes a bearing, a wind driving mechanism and a magnetostrictive piezoelectric mechanism. The wind driving mechanism is arranged on the outer wall of the bearing outer ring 2 to drive the bearing outer ring to rotate. The magnetostrictive piezoelectric mechanism includes a permanent magnet 1 and a piezoelectric assembly. The permanent magnet is arranged symmetrically on the outer wall of the bearing outer ring. The piezoelectric assembly is arranged in the center of the inner cavity of the bearing inner ring. 3 An elastic gasket 7 is provided in the gap of the inner wall.

[0016] The piezoelectric assembly includes a left giant magnetostrictive block 4, a right giant magnetostrictive...

Abstract

The invention provides a magnetostrictive-based rotary piezoelectric breeze power generation device comprising a bearing, a wind-driven mechanism and a magnetostrictive piezoelectric mechanism, wherein the wind-driven mechanism is arranged on the outer wall of a bearing outer ring, and used to drive the bearing outer ring to rotate; the magnetostrictive piezoelectric mechanism comprises permanent magnets and a piezoelectric assembly, and the permanent magnets are arranged on the outer wall of the bearing outer ring symmetrically; the piezoelectric assembly is arranged in the inner cavity center of a bearing inner ring, and a spring washer is arranged in a clearance between both ends of the piezoelectric assembly and the inner wall of the bearing inner ring. The device provided by the invention has the advantages of small volume, high power generation efficiency, little environmental influence, energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of magnetoelectric power generation, and in particular relates to a magnetostrictive-based rotary piezoelectric breeze power generation device. Background technique [0002] As a clean renewable energy, wind energy has a huge global reserve and is valued by countries all over the world. Wind power is the conversion of wind kinetic energy into electrical energy. The principle of existing wind power generation is to use wind force to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser, thereby driving the generator to generate electricity. The existing wind power generation device can be divided into three parts: the wind wheel, the generator and the iron tower. Because the speed of the wind wheel is relatively low, and the magnitude and direction of the wind force often change, the speed is unstable. Therefore, before driving the generator, it is ne...
