A piezoelectric wave energy power generation device and power supply system for offshore lighthouses

Abstract

The invention provides a piezoelectric type wave power generation device. A longitudinal wave power generation assembly utilizes a horizontal ocean current energy power generation assembly as a suspension body to perform longitudinal power generation, the horizontal ocean current power generation assembly can convert impact force of horizontal ocean current into electric energy at the same time, and natural environment is fully utilized to generate power. The piezoelectric type wave power generation device has an ingenious structure and high efficiency, saves time, is simpler and more reliable compared with mechanical type, hydraulic type and air type wave power generation methods and prolongs service life of a power generator. The invention provides a marine beacon power generation system at the same time. The marine beacon power generation system can complementarily generate power through the piezoelectric type wave power generation device, a solar photovoltaic power generation device and a wind power generation device, improves energy output efficiency and stability, guarantees the situation of the same power supply, greatly reduces capacity of energy storage equipment and accordingly reduces beacon investment. In addition, the system also achieves unmanned power supply of the beacon, reduces labor, utilizes regenerable energy in high efficiency at the same time, is green and environmentally-friendly.

Description

technical field [0001] The invention relates to a lighthouse power supply system, in particular to an energy self-sufficient offshore lighthouse power supply system involving wave, light and wind three energies complementary, wherein wave power generation involves the technology of collecting wave vibration power generation by using piezoelectric materials. Background technique [0002] A lighthouse is a tower-shaped light-emitting navigation mark built near key parts of the channel to guide ships or indicate dangerous areas. Lighthouses are mostly located on offshore islands and tidal flats, and it is difficult to lay circuits to transmit electric energy from land power grids; diesel generators supply power, which inevitably pollutes seawater; traditional offshore power generation methods, namely solar and wind power generation, have certain weather conditions Restrictions, when there is extreme weather (dry wind, cloudy), there will be problems with the power supply facili...

AI Technical Summary

Problems solved by technology

At present, the living and working water of the workers on the island is all supplied by the mainland. However, in winter, when the wind is strong, the waves are high, and the current is fast, it is very difficult for ships to berth and leave the dock.
