Floating-type wave energy conversion device

Abstract

The invention discloses a floating-type wave energy conversion device, which comprises a hollow shell, a wave-approach assembly for collecting wave energy, and a conversion assembly for converting thewave energy into electrical energy. The wave-approach assembly comprises wave-approach plates arranged outside the shell, and wave-approach plate idler wheels connected with the wave-approach plates,a moving track is formed in the shell, and the wave-approach plate idler wheels are driven by the wave-approach plates to roll along the moving track; the conversion assembly comprises generators, asupporting sleeve rod, connecting rods and positioning gears, wherein the generators, the supporting sleeve rod, the connecting rods and the positioning gears are arranged in the shell, and the positioning gears are used for positioning the connecting rods; the positioning gears are in transmission connection with rotating shafts of the generators; a sliding piece slidably connected with the supporting sleeve rod is arranged on the supporting sleeve rod; one ends of the connecting rods are hinged to the sliding piece, and the other ends of the connecting rods are hinged to the wave-approach plate idler wheels; the connecting rods are further provided with racks engaged with the positioning gears; and the wave-approach plates are impacted by waves to drive the connecting rods to move through the wave-approach plate idler wheels, and the racks arranged on the connecting rods drive the positioning gears to rotate, and thus drive the generators to generate electricity.

Description

technical field [0001] The invention relates to the technical field of marine renewable energy engineering, in particular to a floating wave energy conversion device. Background technique: [0002] In recent years, with the rapid development of economic construction in coastal areas, coastal industries such as tourism and marine aquaculture have gradually emerged, and the requirements for wave-proof energy storage in coastal waters have become higher and higher. According to statistics and calculations of wave observation data, the theoretical average power of wave energy resources in my country's coastline has reached more than 12 million kilowatts, and the global economically valuable wave energy extraction has reached 100-1000 million kW. As a big energy country, my country's demand for energy is increasing year by year. While using a large amount of non-renewable resources, it is actively looking for renewable new energy that can be replaced. With its clean, pollution-fr...
