Title:
WAVE-ENERGY POWER GENERATION DEVICE IN CONCEALED STATE FOR POWERING UNDERWATER VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/046497
Kind Code:
A1
Abstract:
A wave-energy power generation device in a concealed state for powering an underwater vehicle, the device comprising a wave-absorbing floating body (1), a buoyancy bin (2), a permanent magnet electric motor (3), a storage battery (4), tension legs (5) and a gravity anchor (6), wherein the permanent magnet electric motor (3) and the storage battery (4) are both mounted in the buoyancy bin (2) and are connected to each other; the permanent magnet electric motor (3) comprises a rotor (32); the wave-absorbing floating body (1) is connected to the rotor (32) of the permanent magnet electric motor (3) by means of a connection rod (7), the relative swing of the wave-absorbing floating body (1) and the buoyancy bin (2) drives the permanent magnet electric motor (3) to generate power, and the storage battery (4) is charged with the power; and the buoyancy bin (2) is connected to the gravity anchor (6) by means of the tension legs (5), and the gravity of the gravity anchor (6) is greater than the buoyancy of the buoyancy bin (2). The underwater buoyancy bin (2) and the gravity anchor (6) are moored together by means of the elastic tension legs (5), so that the buoyancy bin (2) keeps stable under the action of waves; and the wave-absorbing floating body (1) is of a light mushroom type and thus has a motion response sensitivity under the action of waves, so that the wave-absorbing floating body (1) and the buoyancy bin (2) move relative to each other to drive the rotor (32) of the permanent magnet electric motor to do work, so as to capture wave energy and generate power.
