Embodiment 1

[0036] like Figure 1 to Figure 3 As shown, this embodiment provides a wave energy conversion device, including a transmission pendulum 3 , a fixing base 1 , and a transmission mechanism and an energy collection mechanism 2 fixedly installed on the fixing base 1 .

[0037] The energy harvesting mechanism 2 comprises a magnetostrictive sheet, an induction coil 2-3, a permanent magnet 2-4 and a magnetically conductive shell 2-5, wherein the magnetostrictive sheet is a Galfenol sheet 2-1, and the bottom bread of the Galfenol sheet 2-1 Covered with a beryllium bronze sheet 2-2, one end of the magnetostrictive sheet is fixed on the side wall of the fixed seat 1, and the other end protrudes outside the magnetically conductive shell 2-5 to form a cantilever beam. The Galfenol sheet 2-1 and the beryllium bronze sheet 2-2 are bonded and connected by epoxy resin, so that the cantilever beam of the magnetostrictive sheet can bear a large bending range. The induction coil 2-3 is wound on...

Embodiment 2

[0055] A wave energy conversion device provided in this embodiment is different from Embodiment 1 in that:

[0056] like Figure 4 As shown, the side wall of the fixed seat in this embodiment is fixedly connected to the support 8 . The wave energy conversion structure and the support are connected and fixed by bolts and nuts, and then placed at an appropriate water depth on the shore. This kind of energy conversion and collection is convenient for water basins without embankments, and it is easy to install and has a wide range of applications. For river basins with embankments, the wave energy conversion device is connected and fixed with the expansion bolt installed on the embankment through screw holes through nuts, and the installation height can be determined according to the actual environmental conditions of the river.

[0057] For other specific structures and implementation steps, please refer to Embodiment 1.

Abstract

The invention belongs to the technical field of wave vibration power generation devices, and specifically relates to a wave energy conversion device, which includes a transmission pendulum, a fixed seat, a transmission mechanism installed on the fixed seat, and an energy collection mechanism. The energy collection mechanism includes a magnetostrictive sheet, Induction coil, permanent magnet and magnetic conduction shell, the induction coil is wound on the magnetostrictive sheet, the permanent magnets are arranged on both sides of the induction coil and fixed in the magnetic conduction shell; The pendulum rod is fixed on the excitation shaft, the transmission pendulum rod is fixed on the transmission shaft, and the transmission shaft and the excitation shaft are rotated and matched by gears; when the wave drives the transmission pendulum rod to swing, the transmission pendulum rod drives the transmission shaft to move, and the excitation shaft is linked Rotate to make the excitation swing rod press down on the magnetostrictive sheet, causing the magnetostrictive sheet to generate strain. Under the action of the magnetic field, the stress change causes the change of the magnetic induction intensity, and the induction coil generates electromotive force to realize energy conversion.

Description

technical field [0001] The invention belongs to the technical field of wave vibration power generation devices, and in particular relates to a wave energy conversion device and a conversion method. Background technique [0002] In today's world, as non-renewable traditional energy such as fossil energy is continuously exploited and utilized, energy is becoming more and more scarce. Therefore, the development of new energy has become extremely important. The environment, weather and geographical and many other restrictions. As a green and renewable energy widely existing in oceans, rivers and river basins, wave energy has large reserves, wide distribution, and is not limited by natural conditions. In oceans, rivers, and river basins, not only natural wind blowing will generate waves, but also passing passenger ships, cargo ships, ferries, etc. will also cause waves, which will increase the frequency of wave generation. Therefore, wave energy is a kind of energy with great po...
