Warped-tail wave energy collecting device based on floating platform

Abstract

The invention discloses a warped-tail wave energy collecting device based on a floating platform. The warped-tail wave energy collecting device comprises a warped-tail wave absorption floater which islocated between a pair of ship type side appendages. The upper end of the warped-tail wave absorption floater is connected with a transmission shaft, and the lower portion of the warped-tail wave absorption floater half floats in water. The two ends of the transmission shaft are connected with the upper ends of the ship type side appendages through a bearing and a bearing support respectively. Awave lifting plate is arranged below the warped-tail wave absorption floater, and the two sides of the wave lifting plate are connected with the ship type side appendages respectively. A front supporting frame and a rear supporting frame are connected between the ship type side appendages. An n-shaped support is transversely arranged above the warped-tail wave absorption floater, and the bottoms of n-shaped support stand columns are fixedly connected to the tops of the ship type side appendages respectively. A hydraulic cylinder is arranged between an upper cross beam of the n-shaped support and the planar back face of the warped-tail wave absorption floater. The design of the device has high cost performance, and is beneficial for industrialization.

Description

technical field [0001] The invention relates to an energy harvesting device in the field of wave energy power generation, in particular to a wave energy harvesting device based on a floating platform with a new tail-swinging wave-absorbing floating body as the main body. Background technique [0002] Wave energy is the most abundant clean energy in ocean energy. The specific form of wave energy is huge forward thrust and upward buoyancy. With the desire and exploration of clean energy, the research on wave energy utilization technology has also made great progress, and a large number of research results have been obtained, which are mainly used in the field of power generation. At present, the wave energy harvesting devices that have been built or made public are mainly divided into two types: shore-based and floating. Shore-based wave energy harvesting devices are greatly affected by coastal terrain and ocean tides, and have high construction and maintenance costs, so they...

AI Technical Summary

Problems solved by technology

The wave-absorbing floating body of this invention is developed from the nodding duck-type device, which improves the wave-facing surface of the wave-absorbing floating body. The floating rotation radius of the wave-absorbing floating body is reduced. In order to keep the whole device stable during operation, the volume of its underwater appendage is correspondingly increased, which makes the overall device cost higher.
