Embodiment 1

[0054] Such as figure 1 As shown, the wave energy generating device of this embodiment includes an energy harvesting component 1 , a conversion mechanism 2 and an amplification mechanism 3 . The conversion mechanism 2 is arranged directly below the energy harvesting part 1, that is, the axis of the conversion mechanism 2 coincides with the axis of the energy harvesting part 1; one end of the amplification mechanism 3 is hinged to the lower part of the energy harvesting part 1, and the other end is connected to the external hinge;

[0055] A plurality of amplifying mechanisms 3 are evenly distributed at equal angles to the axes of the energy harvesting component 1 and the conversion mechanism 2, and in this embodiment, six amplifying mechanisms are evenly distributed at equal angles. When the energy harvesting component 1 is heaving under the action of waves, the energy harvesting component 1 will lift or lower the conversion mechanism 2 through the amplification mechanism 3, ...

Embodiment 2

[0067] Such as Figure 5 shown as figure 1 The structure diagram of the device, in order to further increase the stability of the device, the Figure 4 The enlargement mechanism 3 in carries out the expansion of parallelogram mechanism, is exactly this embodiment figure 1 organization diagram. The amplifying mechanism 3 here includes not only a pull rod 301, a link arm 302 and a damping plate 303, but also a link 304; the number of link arms 302 is two, arranged in parallel up and down, and the two ends of the link 304 are respectively connected The two link arms 302 and two damping plates 303 are respectively hinged to one end of the two parallel link arms 302, and the two damping plates 303 are fixedly connected together.

[0068] but Figure 5 In the mechanism shown, the hinges at both ends of the two link arms 302 constitute a parallelogram mechanism, the hinge at the right side of the damping plate 303 and the link arms 302 is no longer a local degree of freedom, and ...

Embodiment 3

[0072] Such as Image 6 As shown, this institution is Figure 4 A further modification of the mechanism is to adopt more link arms 302 to be arranged in parallel, and to arrange several link arms 304 between the link arms 302 arranged in parallel. According to the characteristics of the parallelogram mechanism, all links 304 and more than 2 The connecting rod arms 302 are all virtual constraints, which can be omitted when calculating the degrees of freedom, that is to say, the connecting rod 304 may not be set when the device is designed, and when the connecting rod 304 is set, several damping plates may not be connected into one body, When the connecting rod 304 is not provided, several damping plates need to be connected into one body.

[0073] After the micro-amplitude wave acts on the energy harvesting component 1, it will cause a small displacement movement of the energy harvesting component 1, but under the action of the amplification mechanism 3, the linear motion disp...

Description

technical field [0001] The invention relates to a wave energy generating device, in particular to a wave energy generating device and an amplification mechanism under low energy flux density. Background technique [0002] After the 21st century, with the continuous advancement of sustainable development, more and more countries are paying more attention to the development and utilization of marine energy. Various power generation systems, platforms and The research and development of the device came into being. At present, for the development and utilization of wave energy, there are many types of power generation devices. Due to the different mechanisms of device capture wave energy, the installation location and water depth conditions of the device are different, and the ways of converting wave energy into electrical energy are also various. According to the working principle of the device, wave power devices can be roughly divided into three categories, including oscilla...
