Shore-based wave energy generation system adapting to tidal level changes

Abstract

The invention belongs to the technical filed of marine energy resource development and utilization, and particularly relates to a shore-based type wave energy power generation system adapted to tide level variation. The system comprises a shore base, a guide chute and a sliding device, wherein the shore base is arranged on a shore; the guide chute is longitudinally fixed on the shore base; the sliding device can slide vertically along the chute; a break device is configured at the top of the sliding device; a vertical pressure sensor is mounted at the bottom of the break device; the sliding device is fixed on a foundation framework; a plurality of floating boxes are embedded into the foundation framework and are hinged with the foundation framework through float arms; and main equipment of the power generation system is mounted on the shore base. The power generation system is arranged on the shore, so that the maintenance is facilitated, and at the same time, the security and the stability of a generator set are improved greatly; and the work of the power generation system doesn't need manual operation, under the condition that external energy is utilized as little as possible, working heights of floats are adjusted with the tide level variation timely, the reliability is high, the power generation cost is low, and competitiveness of the development and utilization of wave energy is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of marine energy development and utilization, and in particular relates to a shore-based wave energy power generation system that can adapt to changes in tidal levels with the help of external energy sources to a minimal extent and without manual operation. Background technique [0002] In today's society, energy shortages and environmental pollution are becoming more and more serious. Marching into the ocean and developing and utilizing marine energy has become an important way to expand human living space, increase energy reserves, and protect the natural environment. All countries in the world are paying close attention to the development and utilization of marine energy. , Continuously strengthen the marine development strategy, and the Chinese government also solemnly proposed the idea of ​​building a marine power at the recently concluded 18th National Congress of the Communist Party of my country.

Problems solved by technology

At present, most wave energy power generation systems use hydraulic self-elevating systems to realize the above-mentioned lifting functions. Although the effect is good, a large amount of external energy is used to increase the cost of power generation, which is not very consistent with the original intention of developing and utilizing new energy.
