Abstract

The invention provides a power generation device utilizing ocean wave energy. The power generation device comprises a piezoelectric energy harvesting device arranged on a levee. The piezoelectric energy harvesting device comprises piezoelectric structure units. Each piezoelectric structure unit comprises an arched copper plate. A plurality of piezoelectric films are mounted inside each piezoelectric structure unit. The two ends of the piezoelectric energy harvesting device are fixed on a sliding rail through connecting rods. The piezoelectric energy harvesting device is connected to a power source control device through a wire so as to output power energy. By utilizing the power generation device, damage of waves to the levee can be relieved, the life is prolonged, spontaneous power energy supply can be also obtained, energy resource waste is reduced, and great economic benefits are obtained.

Description

technical field [0001] The invention relates to a power generating device utilizing ocean wave energy. Background technique [0002] With the development of my country's economy and the rapid improvement of people's living standards, the shortage of electricity has become increasingly prominent. The mainland of China has the longest coastline in the world, with a total length of about 18,000 kilometers, and another 14,000 kilometers of island shores. The Wanli coast and the island coastline contain huge wave energy. According to preliminary estimates, its theoretical reserve is about 70 million kW, which has very broad development and application prospects. Compared with other energies, ocean wave energy has the advantages of eco-environmental protection and economy. If it can be effectively used, it will play a vital role in our country and even the world. [0003] Taking the levee as an example, the levee in our country bears the uninterrupted impact of waves every day. ...
