Eye-imitating wave energy collector

Abstract

The invention relates to an eye-imitating wave energy collector which comprises transmission assemblies, electromagnetic power generation assemblies, coil arrays, piezoelectric cantilever beam assemblies, a coil panel and side plates. The two side plates are symmetrically arranged relative to the coil panel; the transmission assemblies are installed on the outer sides of the side plates; the electromagnetic power generation assemblies are installed on the inner sides of the side plates; the front face and the rear face of the coil panel are each provided with two sets of coil arrays in an embedded mode; the coil arrays and the electromagnetic power generation assemblies are arranged correspondingly; the coil panel and the side plates are installed on a lower installation base through lug bases; an upper cover is installed on the lower installation base; the piezoelectric cantilever beam assemblies are installed at the lug bases of the coil panel; a waterproof sealing rubber strip is installed in a groove of the connecting face of the lower installation base and the upper cover; the transmission assemblies swing left and right under excitation of sea waves and drive the electromagnetic power generation assemblies to rotate; and the electromagnetic power generation assemblies and the coil arrays generate relative motion and then generate power through electromagnetic induction. Compared with the prior art, according to the eye-imitating wave energy collector provided by the invention, the wave energy in the marine environment can be effectively collected for power generation under the excitation of low-frequency irregular waves.

Description

[Technical Field] [0001] The present invention relates to the field of sea wave energy harvesting technology, in particular to a simulated profile electromagnetic eye - Piezoelectric Composite ocean wave energy harvester. [Background technique] [0002] Unmanned probe, wireless sensors can be used for marine equipment condition monitoring, ecological resources marine environment detection and monitoring, it helps protect the environment and marine marine economy. However, complex marine environment, vast area, power supply difficulties. Generally there is a short battery life, pollution of the environment, difficult maintenance problems, and the high power device or a large marine power cable arrangement cost manner, a large impact on the marine ecology, and apply only to the coastal waters. [0003] Marine environment rich in natural distribution of energy available for use, the wave energy is one of the most widely distributed and may be large-scale use of renewable energy, the...

AI Technical Summary

Problems solved by technology

However, there are still two key problems in ocean wave energy harvesting: one is the low-frequency (0.1-2Hz), irregular wave excitation, which is not conducive to electromechanical conversion, and it is easy to cause instability and damage to the harvester; the other is the harsh marine environment. Seawater erosion and ocean current erosion seriously affect the reliability and life of devices

In addition, the current ocean wave energy harvesters still have problems such as low device power and low electromechanical conversion efficiency.
