Flexible piezoelectric device generating power by utilizing ocean energy

Abstract

The invention belongs to the technical field of ocean wave energy collection, and particularly relates to a flexible piezoelectric device generating power by utilizing ocean energy. The flexible piezoelectric device comprises an air bag and a piezoelectric power generation device, wherein the piezoelectric power generation device comprises a cylindrical shell body, flexible piezoelectric plates and weight blocks; a sealed space is formed between the upper surface of the shell body and the air bag the lower surface of the shell body is connected with a mooring device at the water bottom; one end of each flexible piezoelectric plate is connected with the inner side of the upper surface of the shell body, and the other end is connected with the corresponding weight block; and a group of the flexible piezoelectric plates comprises at least one flexible piezoelectric plate, the flexible piezoelectric plates in the same group are evenly arranged in the radial direction of the upper surface of the shell body, and the flexible piezoelectric plates in different groups are evenly and circumferentially arranged around the circle center of the upper surface of the shell body. The flexible piezoelectric device is simple in structure and high in practicability, can recover ocean wave energy efficiently, satisfy the electricity utilization demands of majority small electronic equipment, and has a positive effect on saving resources and protecting environment.

Description

technical field [0001] The invention belongs to the technical field of ocean wave energy collection, and in particular relates to a flexible piezoelectric device that utilizes ocean energy to generate electricity. Background technique [0002] Ocean energy is one of the earliest energy sources that human beings began to study. The development of ocean energy has been started since the end of the eighteenth century. However, compared with other energy sources, the environment of ocean energy is harsh and the development is relatively lagging behind. Since the ocean area accounts for 71% of the total area of ​​the earth, and ocean energy is a clean renewable energy, it is an inexhaustible clean energy source, so various countries continue to increase investment in the exploration of ocean energy. With the continuous development of science and technology, many countries, especially countries rich in ocean energy resources, have given great support to the development of ocean en...
