Sea wave and wind power generation device

Abstract

The invention discloses a sea wave and wind power generation device which is characterized by comprising a closed cavity and at least three micro power generation structure bodies. Each micro power generation structure body is composed of an elastic component, piezoelectric material, a permanent magnet and a coil, the micro power generation structure bodies are fixed on the inner wall of the cavity, the axial lines where the three micro power generation structures are positioned are in a three-dimensional orthogonality state, the inner space of the cavity is of a certain size, therefore the device can be supported to float on the water, the piezoelectric material is fixed on the outer surface of the elastic component, each elastic component drives two power generation units simultaneously to output electric energy outward, one power generation unit outputs electric energy by adoption of the direct piezoelectric effect of the piezoelectric material, and the other power generation unit outputs the electric energy by adoption of the electromagnetic induction principle.

Description

[0001] technical field [0002] The invention relates to the field of new energy facilities, in particular to a wave and wind power generation device. Background technique [0003] The energy shortage in today's world, the search for new energy is the most urgent desire of the world, especially the search for renewable energy on the earth is the goal pursued by people. The waves of the oceans on the earth are a kind of huge energy. People are constantly trying to find various methods to develop this huge renewable energy, practice exploration, and develop various types of power generation devices. [0004] Scholars at home and abroad have proposed a variety of wave power generation methods, most of which use various mechanical devices to convert the reciprocating linear motion of waves into rotational motion, and then use a rotating motor for energy conversion, or use a linear motor to convert energy. However, regardless of whether a rotary motor or a linear motor is used, ...

AI Technical Summary

Problems solved by technology

However, regardless of whether a rotary motor or a linear motor is used, due to the slow motion of the waves, the volume and mass of the generator are generally large, and the manufacturing cost is relatively high. Reduced system efficiency, need for regular maintenance, etc.

[0005] Existing wind turbine power generation devices generally include a wind turbine mechanism. Due to the influence of the application environment of water surface power generation, the installation height of the wind turbine mechanism is limited. certain degree of difficulty

The wind turbine mechanism is exposed to the air and has a certain height, which is easily damaged by wind and waves, resulting in failure to work. It is very difficult to maintain the power supply of floating platforms, especially in locations far away from the coastline

In addition, the cost of the wind turbine mechanism is relatively high, and there is a minimum starting wind speed in the wind turbine power generation method, below which the wind speed will not work normally
