Title:
COMPOUND PENDULUM FREQUENCY-RAISING TYPE WAVE ENERGY COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/077854
Kind Code:
A1
Abstract:
A compound pendulum frequency-raising wave energy collection device, comprising a housing (1) that floats on the water surface and wobbles with waves, a compound pendulum mechanism (2) that is rotatably disposed in the housing (1) and rotates with the wobbling of the housing, a driving gear (3) that is rotatably disposed in the housing (1) and rotates synchronously with the compound pendulum mechanism (2), an electromagnetic power generation mechanism (4) that is disposed in the housing (1) and is used for meshing transmission with the driving gear (3) to generate power by means of electromagnetic induction under the drive of the driving gear, and a piezoelectric power generation mechanism (5) that is disposed in the housing (1) and located above the end surface of the driving gear (3) and is used for deforming during rotation to generate power by means of the piezoelectric effect, such that when the housing (1) wobbles non-directionally with wave undulations, the compound pendulum mechanism (2) rotates non-directionally to adapt to dynamic changes of the wave energy on the water surface, so as to achieve a high energy capture efficiency. In addition, the energy conversion performed by the electromagnetic power generation mechanism (4) and the piezoelectric power generation mechanism (5) by means of two different electromechanical coupling energy conversion means is applicable to a wide spectrum range of wave energy, and achieves a high adaptability and high conversion efficiency.
