Offshore self-anchored wave power generation device

Abstract

The invention discloses an offshore self-anchored wave power generation device is composed of a transverse wave energy collecting module, a longitudinal wave energy collecting module, a telescopic adjusting module, an anchoring module and a body. The oscillation floater type power generation is adopted, and the advantages of being small in manufacturing difficulty, low in cost, high in efficiency, simple in floater manufacturing and the like are achieved; the transverse wave energy collecting module and the longitudinal wave energy collecting module enable the device to collect transverse and longitudinal wave energy at the same time, comprehensive utilization of transverse movement and longitudinal movement of waves is achieved, and the power generation efficiency is effectively improved; the anchoring module can be automatically drilled and anchored to the seabed, and the function of anchoring the power generation device in the sea is achieved; the mechanical telescopic adjusting module can dynamically adjust the height of the power generation device along with the sea surface height, so that the floater works within the optimal stroke range; and the device is simple in overall appearance, the main body parts are all installed in the body, the core part of the power generation device is isolated from seawater, and sealing performance and corrosion resistance are good.

Description

technical field [0001] The invention belongs to the technical field of ocean energy, and in particular relates to a self-anchored wave energy generating device suitable for offshore. Background technique [0002] With the development of the world economy, the surge of population and the progress of society, people's demand for energy is increasing day by day. The vast ocean, which accounts for 70% of the earth's surface area, concentrates 97% of the water and contains a large amount of energy, including wave energy, tidal energy, ocean current energy, temperature difference energy, and salt difference energy. Among them, wave energy, as a clean and renewable energy, has huge reserves, and the use of wave energy to generate electricity has become a research trend in the world's ocean powers. my country has abundant wave energy resources, but the problem of power transmission in the deep sea is still unsolved, and the devices suitable for deep sea are generally large in size,...

Problems solved by technology

[0014] In order to solve the above problems, the present invention provides a self-anchored wave energy power generation device suitable for offshore. The device is provided with an anchor module. When the anchor claws rotate, because the external threads of the anchor claws match the threaded holes on the anchor shell, the three anchor claws will spin out and drill into the seabed rock formation when they rotate, and the opened anchor claws will It can realize the anchoring of the power generation device in seawater, which solves the problem that the existing device needs to be manually lowered into the sea to anchor the device
