Title:
WAVE DIRECTION SELF-ADAPTIVE MULTI-WATER-CHANNEL WAVE FOCUSING-TYPE WAVE ENERGY POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/068191
Kind Code:
A1
Abstract:
Disclosed is a wave direction self-adaptive multi-water-channel wave focusing-type wave energy power generation device, comprising an energy collection system, an energy conversion system, and a supporting system. Waves are focused by means of double water channels (29), and the motion amplitude of mass points of water behind a box body (2) is doubled. The device is connected to a fixed pile column (15) by means of a universal bearing (13), an opening of the device faces a wave flowing direction at all times, the device adapts to different seasons and water area conditions, the requirement for the environment is low, and the device can be used in expansive sea areas. Several circles of pre-stretching spring pressing pieces (16) are arranged in a winding reel (22), and it is guaranteed that a nylon rope (7) connected to a float (3) is always in a straightened state whether the float is located at the wave crest or the wave trough, and a situation wherein the nylon rope (7) derails from a pulley block (8) and cannot work normally due to looseness is avoided. A pawl (27) is fixed on a fixed gear (28) connected to a ratchet wheel (26), such that the ratchet wheel (26) is driven to operate by rotation in only one direction in two-way rotation of the winding reel (22), one-way energy storage of a flywheel rotor (17) in a power generation cabin is determined, and the kinetic energy upper limit of the flywheel rotor (17) is limited.
