Electromagnetic type vibration energy recovery device

Abstract

The invention discloses an electromagnetic type vibration energy recovery device, which comprises a drive module, an energy feedback module and a support module; by a symmetrical structure, the drive module carries out reciprocating linear motion under the action of external force to drive the energy feedback module; the energy feedback module converts the reciprocating linear motion into one-way rotary motion and generates electricity; the support module guides and supports the drive module and the energy feedback module; a screw in the drive module converts the linear motion into the rotary motion of an inner rotor in the energy feedback module through a screw-nut pair; an outer rotor in the energy feedback module is a permanent magnet; one-way power transmission is achieved by contact and separation of the inner rotor and the outer rotor through the conical surface; the outer rotor and a stator assembly rotate oppositely to generate electricity; and the stator assembly comprises a coil bracket and a coil. By the electromagnetic type vibration energy recovery device, the efficiency of the vibration energy recovery device can be effectively improved; the structure is simple and compact; and the mechanical transmission loss of energy can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to an electromagnetic vibration energy recovery device capable of high-efficiency energy recovery. Background technique [0002] Vibration is almost everywhere, and energy recovery technology that stores or converts the mechanical energy brought about by vibration is of great significance. At present, the principle of recovering vibration energy is mainly divided into five types: electromagnetic induction, piezoelectric effect, electrostatic effect, pneumatic energy storage and hydraulic energy storage. Among them, the electromagnetic vibration energy recovery technology has high recovery efficiency and high energy recovery power, and has been extensively studied. [0003] The existing electromagnetic vibration energy recovery devices mainly have two forms, one is to convert the linear motion into the rotary motion of the rotor of the rotary generator through the ...
