A flexible cavity type marine wave energy power generation device

Abstract

The invention discloses a flexible cavity type ocean wave energy power-generating device which is used for driving an ocean structure. The flexible cavity type ocean wave energy power-generating device comprises a flexible cavity body, a hydraulic motor and a generator, wherein the hydraulic motor and the generator are both fixed in the ocean structure and are connected through a drive device, the flexible cavity body is communicated with one end of the cavity of the hydraulic motor through a pipe I, and the other end of the cavity of the hydraulic motor is communicated with a sea opening through a pipe II. In the flexible cavity type ocean wave energy power-generating device, the flexible cavity body is directly in contact with waves, wave force is directly exerted to the flexible cavity body, and external wave acting force can be collected to the maximum extent. Inlet and outlet flows are alternatively produced through alternate change of the volume of the flexible cavity, accordingly considerable energy supply can be achieved, the generator is driven by the hydraulic motor, energy is converted into electric power, and the electric power is continuously and effectively supplied for navigation, instrument observation and other operation activities of ocean structures including an AUV and the like.

Description

technical field [0001] The invention belongs to the field of ocean wave energy generating devices, in particular to a flexible cavity type ocean wave energy generating device. Background technique [0002] Small marine vehicles, including AUV (Autonomous Underwater Vehicle, autonomous underwater vehicle), underwater glider (Glider), wave energy glider (Wave Glider) and other forms, are used to observe various technical parameters of the ocean system, and require long-term Sailing in the ocean. Energy supply is an important constraint. AUVs and underwater gliders usually carry batteries. Limited by battery capacity, the duration of sea voyages is limited. When the battery is exhausted, the vehicle must be recovered to replace the power supply before the next mission can begin. Due to the extremely energy-saving underwater gliding motion, the underwater glider has a long voyage period, but because it does not have a sustainable energy supply with it, it must be recycled when ...
