Abstract

The invention relates to an energy conversion device, in particular to an oscillating type hydrofoil end vibration excitation wave energy conversion device. The problems that an existing wave energy power generation device is complex in structure and high in device manufacturing cost, high in power generation cost and low in energy conversion efficiency and power generation voltage are solved. The oscillating type hydrofoil end vibration excitation wave energy conversion device comprises a fixed base, a water isolation plate, an oscillating wing plate, two supporting bases, two sets of cantilever beam piezoelectric energy floaters, a plurality of vibration excitation permanent magnets and a plurality of vibration receiving permanent magnets. Each set of cantilever beam piezoelectric energy floaters includes a plurality of cantilever beam piezoelectric energy floaters. The fixed base is provided with grooves. The two supporting bases are fixedly installed on the fixed base in parallel. The water isolation plate is placed below the oscillating wing plate and covers the grooves. The water isolation plate is in sealed connection with the fixed base. The two sets of cantilever beam piezoelectric energy floaters and the multiple vibration receiving permanent magnets are arranged inside the grooves. The cantilever beam ends of the multiple cantilever beam piezoelectric energy floaters are fixedly connected with the fixed base. The oscillating type hydrofoil end vibration excitation wave energy conversion device is used for energy conversion and power generation.

Description

technical field [0001] The invention relates to an energy conversion device, in particular to a swing type hydrofoil end excitation wave energy conversion device, which belongs to the field of new energy for ocean wave power generation. Background technique [0002] In recent years, with the increasingly serious energy crisis, new energy technologies have received widespread attention. On some remote islands or offshore operating platforms far from the coastline, energy is scarce and material transportation costs are high, resulting in some equipment not working properly, which brings great inconvenience to the life of island residents and platform staff. The ocean is a very huge energy treasure house. It is estimated that the energy contained in sea waves is as high as 5000GW. If it can be effectively used, it will not only solve the energy problem of people at sea, but also greatly help to alleviate the global energy crisis. Ocean energy reserves are abundant. How to col...
