Title:
BLADE-TYPE ZERO-MASS INERTIA HIGH-EFFICIENCY POWER GENERATION WAVE ENERGY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/046496
Kind Code:
A1
Abstract:
A blade-type zero-mass inertia high-efficiency power generation wave energy device, comprising: a wave absorption floating body (1), which comprises a wave absorption floating body underwater thin-walled arc-shaped portion (12) and a wave absorption floating body overwater flat plate portion (11); and a support truss (2), one end of which is connected and mounted in the wave absorption floating body underwater thin-walled arc-shaped portion (12), and the other end of which is hinged to a support base (3), wherein the mounting position of the support base (3) is positioned at the center of a circle of the wave absorption floating body underwater thin-walled arc-shaped portion (12). Under the action of incident waves, the blade-type wave absorption floating body receives excitation from the incident waves to perform a pitching motion and drive a hydraulic cylinder to do work, and the wave absorption floating body starts rotating around a hinged rotation support point simultaneously. Due to the arc shape on the rear of the wave absorption floating body, pitching does not create waves and does not generate radiation damping to dissipate energy. Secondly, due to the light weight of the blade-type wave absorption floating body, less energy is required during the rotation thereof, and most of the work applied on the floating body by waves is obtained by a PTO energy conversion system, which improves the efficiency of the wave energy device capturing energy.
