Embodiment Construction

[0014] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0015] The ellipsoid (2), support shaft (5) and support ball of this multi-node telescopic rod type wave energy power generation system are all connected by telescopic rods (8) and cross shafts (7, 9), and each node is telescopic Strictly limit two-dimensional movements such as up and down pitch and stretching in the pitch direction to ensure system flexibility and stability. The support ball and the support frame are integrated by rigid objects, which strictly limit the effective moment reference point of the energy capture of the ellipsoid floating motion, in which the support ball and the balance body are used as the floating support body of the support structure.

[0016] The ellipsoid (2) is the wave energy capture body of the wave energy generation system. It floats up and down under the action of waves. When the ellipsoid moves from the trough to the crest ...

Abstract

The invention discloses a multi-joint stretchable rod type wave power generation system which comprises a wave energy capture part, a hydraulic pump high-pressure storage part and a hydraulic expansion power generation part. The wave energy capture part is of a triune efficient capture structure composed of a supporting shaft, stretchable rods and a spheroid. The ellipsoid moves up and down under the wave action, and the stretchable rods are driven to pitch by using the supporting rod as the pivot and are stretched in the direction of the supporting shaft. A motion base point is formed by interaction of a supporting frame, a supporting ball and the supporting shaft. The stretching motion of the stretchable rods on the two sides of the spheroid is mechanically coupled through a conical gear, a change wheel, a ratchet wheel and a hydraulic pump, so that low-pressure oil is compressed and stored to a high-pressure oil tank. A hydraulic motor and a direct-current generator are optimally controlled through high-pressure oil under the cooperation of a flow valve, a Boost current transformer and an inverter, and efficient conversion from hydraulic energy to electric energy is achieved. The wave energy capture efficiency is effectively improved, the wave energy power generation application range is enlarged, and new-energy industry development is greatly promoted.

Description

technical field [0001] The invention relates to a multi-node telescopic rod type wave energy power generation system, in particular to a power generation system for capturing wave energy in vast oceans. Background technique [0002] With the energy crisis and environmental deterioration, completely pollution-free wave energy has received widespread attention from scientific researchers in various countries. Wave energy is the potential energy and kinetic energy produced by the periodic movement of seawater, and its essence is produced by wind energy acting on the sea level. Hundreds of wave power generation systems have been put into operation around the world, mainly including oscillating water column type, oscillating float type, swinging type, nodding duck type, etc. Problems such as poor wave impact ability. Therefore, it is of great practical significance to develop a wave power generation system with high energy conversion efficiency, strong mobility, and strong resi...
