Offshore wave energy conversion and utilization device

Abstract

The invention relates to an offshore wave energy conversion and utilization device. The technical problems of incapabilities of effectively absorbing energy transmitted by waves and being automatically adapted to tide rising and falling and low conversion efficiency of the conventional wave energy conversion and utilization device are mainly solved. The offshore wave energy conversion and utilization device comprises a buoy, a support frame, two groups of telescopic cylinders, a swinging frame and a support, wherein the buoy is fixed on the support frame; the support frame is hinged to the swinging frame; the swinging frame is hinged to the support; the two ends of the first telescopic cylinder are hinged to the support frame and the swinging frame; the two ends of the second telescopic cylinder are hinged to the swinging frame and the support respectively. According to the device, the buoy is used as a main wave energy receiving body, and the acting force and a horizontal component of a vertical oscillating water body forming waves can be utilized, so that the conversion efficiency is improved; a foldable boom structure is adopted, so that the total travel of the telescopic cylinders can be shortened, the pressure rod stability of the telescopic cylinders is ensured, and the device can be automatically adapted to tide rising and falling; the device has the advantages of reducing seawater erosion and avoiding the adverse impact of marine sludge and attachments, and the movement reliability is improved.

Description

technical field [0001] The invention relates to a conversion and utilization device, in particular to an offshore wave energy conversion and utilization device. It has high energy conversion efficiency and can automatically adapt to tide level changes. Waves can make giant ships go up and down, which contains huge energy. Wave energy is a new energy source that can be developed and utilized for power generation or as a power source in areas such as seawater desalination. Background technique [0002] At present, among the known various offshore wave energy mechanical conversion devices, there are floating type and base fixed type. The floating type is anchored to the seabed with chains, and the civil construction cost is low, but it is inconvenient to manage and the shore cable is easily damaged; the base fixed type is easy to manage and lay the shore cable, so it is widely used. Among various types of base-fixed wave energy mechanical conversion devices, the more typical ...

Problems solved by technology

However, the lower the sea tide level, the more the baffle tends to be vertical, and the lower the utilization rate of the wave up and down oscillating water body, which is not conducive to the improvement of the wave energy conversion rate
