Embodiment Construction

[0021] The specific implementation of the present invention will be further described below in conjunction with accompanying drawing:

[0022] Such as figure 1 Shown is a schematic structural diagram of a hybrid wave energy conversion device, which is a loosely moored semi-submersible floating body. The relative position of the device in the sea area is realized by the anchor 6, and the damping plate 7 is connected with the anchor 6 through the anchor cable 5. The damping plate 7 is a cylindrical solid disc, and the net buoyancy force received by itself is negative, so the tension cable 4 is always in tension. The damping plate 7 relies on the inertia of itself and the attached water body. When the wave acts, the position of the damping plate 7 basically does not move. At the same time, the tension cable 4 has an appropriate length so that under the action of a specific wave, the damping plate 7 is vertical to the buoy 3. The direction of the wave excitation force in the dir...

Abstract

The invention discloses a mixed-type wave power generation device. The device is composed of a wave energy conversion device capable of absorbing kinetic energy of a floater in multiple degrees of freedom, and a hydraulic type energy output system arranged inside the wave energy conversion device, and belongs to a wave power generation device. 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...
