Embodiment Construction

[0018] The working principle of the power generation device is: the power generation device absorbs and converts the complex and changeable movement of the ocean waves into the relative linear reciprocating motion between the lower feeding part and the buoyant body, and the magnet on the feeding sensing part moves back and forth linearly with the lower feeding part. During the movement, the non-contact reciprocating impact on the metal cantilever beam with magnets bonded to the left platen part and the right platen part, the metal cantilever beam is forced to vibrate; The charge output is connected to the cable through the wire, and the electric energy generated by the piezoelectric body is stored by an external rectification processing circuit, and finally supplies power for watt-level marine equipment such as a navigation light; the feed sensing part is connected with four sets of compression springs, In the case of no waves, the wave potential energy stored due to elastic de...

Abstract

The invention discloses a device for generating electricity by using sea waves and belongs to the technical field of comprehensive utilization of sea energy. In the sea electricity generation device, an outside screw thread is formed at the lower end of a central shaft of a lower feeding component; and a damping board upper nut, a damping board and a damping board lower nut are arranged on the outer screw thread sequentially. Two groups of pressing board components which are symmetric with each other left and right and have the totally same structures are arranged in the electricity generation device; and a feeding sensing component has a symmetric structure. Four groups of screw thread shaft components and two groups of piezoelectric generator components which have the totally same structures and are distributed symmetrically are arranged in the device. The device has a simple structure, low cost and high energy conversion efficiency; by adoption of a piezoelectric energy conversion structure, the piezoelectric generator is indirectly driven to generate electricity by a permanent magnetic force without an acceleration mechanism; therefore, the device is applicable to complicated and irregular wave environments and used for electricity generation in shallow sea areas and open sea areas.

Description

technical field [0001] The invention relates to a device for generating electricity by using ocean waves, which belongs to the field of ocean energy devices. In particular, it relates to the field of electromechanical technology through the conversion of wave energy-mechanical energy-electric energy by using the basic principle of piezoelectric power generation. Background technique [0002] Ocean energy is a clean, non-polluting renewable energy, and wave energy, as the ocean energy with the best quality, highest energy flow density and widest distribution, has attracted increasing attention. Reasonable use of wave energy is of great significance for power supply of micro-ocean equipment such as navigation lights. At present, the energy supply methods of navigation lights mainly include: solar energy, aluminum-air primary batteries, batteries, and wave energy. Solar energy is vulnerable to weather; aluminum-air primary batteries (StephanieV.Chasteen, N.Dennis Chasteen, Pa...
