The wave energy conversion device captures wave energy and further converts the energy into mechanical reciprocating motion, and the hydraulic type energy output system conducts peak clipping and valley filling on captured fluctuation energy and outputs the energy to an electric generator stably. The mixed-type wave power generation device has the characteristics of being high in energy capture width ratio and sea condition adaptability, and meanwhile capable of capturing the kinetic energy of the floater in multiple degrees of freedom, thereby being a mixed-type wave energy conversion device.

Description

technical field [0001] The invention belongs to the field of wave energy power generation, and relates to a hybrid wave energy power generation device, in particular to a hybrid wave energy conversion device capable of absorbing motion energy of multiple degrees of freedom of a float, and including its hydraulic energy output system. Background technique [0002] As a renewable green energy, wave energy has broad application prospects. Wave energy is also one of the energy sources with the largest reserves and the largest exploitable amount among various ocean energy resources. So far, the large-scale and commercial utilization of wave energy is still immature, and most of them are still in the stage of basic theoretical research, laboratory tests and prototype trial operation. Only a few wave energy devices have been put into practical use and have undergone grid-connected trial operation. For wave power generation, in addition to the technology, reliability and efficiency...

Problems solved by technology

For these ocean observation methods, power supply is a problem that has to be considered

Especially for the power supply of deep-sea underwater sensor network nodes, laying long-distance cables is expensive, and the working hours of batteries are limited, and solar energy is affected by weather and sea conditions. Therefore, it is very important to find a sustainable energy supply solution that can be selected locally. Such as wave energy, temperature difference energy, salt difference energy, etc.
