Gravity Pendulum-Slider Type Floater Wave Power Generation Device

Abstract

The invention provides a gravity pendulum-sliding block type floater wave energy power generation device, and belongs to the technical field of utilization of ocean renewable energy sources. The device comprises a buoyancy tank, a gravity pendulum, a hydraulic-type energy conversion system and a stand, wherein the gravity pendulum, the hydraulic-type energy conservation system and the stand are arranged inside the buoyancy tank. The gravity pendulum comprises a gravity pendulum main body, a large-mass sliding block and a reset spring and other parts. The gravity pendulum is arranged on the stand through omni-directional hinged supports in a lifting mode, and the gravity pendulum can be swung around a lifting point in any direction. The large-mass sliding block can slide relative to the axis of the gravity pendulum main body through a slide way. In a static state, the sliding block can be maintained in a balance position through the reset spring. The buoyancy tank can ascend, descend and waggle under the wave effect, so that the gravity pendulum can move relative to the stand by relying on the inertia force and the gravity effect, and large-mass sliding block can move relative to the gravity pendulum main body by relying on the inertia force and the gravity effect. The swing of the gravity pendulum and the movement of the large-mass sliding block are used for driving hydraulic cylinders and other devices, and wave energy is extracted.

Description

technical field [0001] The invention belongs to the technical field of marine renewable energy utilization, and relates to a float power generation device utilizing wave energy. Background technique [0002] Under the background of global energy shortage and increasing emphasis on environmental protection, the utilization technology of clean and renewable energy has gradually become a research hotspot. Wave energy is widely distributed in the ocean and has a large amount of reserves. It is a marine renewable energy with broad development prospects. At present, the devices using wave energy to generate electricity are mainly divided into five categories: oscillating water column type, floating raft type, float type, pendulum type and wave-surpassing type. Among them, the float-type wave energy generating device has a simple structure, flexible size selection, and broad development prospects. Conventional floater wave energy generating devices only use the up and down moveme...

AI Technical Summary

Problems solved by technology

Conventional floater wave energy generators only use their up and down movement in waves, and cannot effectively extract energy from horizontal movement, thus reducing energy utilization

In addition, the existing float device is usually a multi-body type, that is, the float moves with the wave surface, and the energy conversion system is placed in another static and sealed working cabin, and the energy is extracted by the relative motion of the float and the static cabin, so that the static The sealed cabin needs openings to allow moving components to pass through, which requires high sealing and anti-corrosion performance, which increases product design and manufacturing costs
