The first friction layer 22 material and the second friction layer 42 material have a difference in friction electrode order. As can be seen from the above structure, the first friction layer 22 and the second friction layer 42 are made of different materials, and there is a difference in the order of the friction electrodes and a material with a large difference in the electron loss is preferable, that is, the materials with different orders of the attraction degree of the charges are selected.

Embodiment III:
see fig. 1-6. On the basis of the second embodiment, the floating body 03 comprises a push cylinder 31, a sleeve plate 32 and a buoy 34; the upper end of the buoy 34 is connected with the sleeve plate 32 through an elastic piece 33; the shell 02 is fixedly connected to the sleeve plate 32; the support body 05 is fixedly connected with the sleeve plate 32; the pushing cylinder 31 is fixedly connected above the buoy 34, and the upper end of the pushing cylinder 31 penetrates through the sleeve plate 32 and goes deep into the shell 02; the push cylinder 31 is used to apply a force in the up-down direction to the friction body 04. As can be seen from the above structure, the bottom of the floating body 03 is a buoy 34, and the floating body drives the buoy 34 to move up and down due to the floating of the waves, two ends of the elastic member 33 are fixed on the buoy 34 and the sleeve plate 32, and the up and down movement of the buoy 34 causes the elastic member 33 to compress or stretch; the sleeve plate 32 is connected with the support body 05, the support body 05 is kept fixed, the sleeve plate 32 is kept fixed, the shell 02 and the screw body 01 are placed on the sleeve plate 32 and also kept fixed, so that the push cylinder 31 moves up and down under the floating of the buoy 34, and the friction body 04 is pushed to move up or move down along with gravity.
The push cylinder 31 is arranged in the center of the buoy 34; the elastic pieces 33 are two groups and are symmetrically arranged about the push cylinder 31; the support body 05 comprises a support plate 52 and a support shaft 51 fixedly connected with the support plate 52; the support plate 52 is stationary; the support shaft 51 is fixedly connected to the sleeve plate 32. As is apparent from the above structure, the sleeve plate 32 is connected to the support body 05, the support shaft 51 is connected to the support plate 52, and the support plate 52 is kept fixed, so the sleeve plate 32 is kept fixed. The push cylinder 31 is arranged at the center of the buoy 34, the elastic members 33 are arranged in two groups and are symmetrically arranged about the push cylinder 31, so that the push cylinder 31 can better apply force along the up-down direction to the friction body 04 when the wave floats. The working principle is as follows: when the wave floats, the buoy 34 floats up and down on the wave surface, and both ends of the elastic member 33 are fixed to the buoy 34 and the sleeve plate 32, respectively. Because the supporting body 05 acts, the sleeve plate 32, the shell 02 and the spiral body 01 are kept fixed, the pushing cylinder 31 can move up and down under the drive of the buoy 34, and the pushing cylinder 31 pushes the friction body 04 to move upwards or move downwards along with gravity; since the friction body 04 is sleeved on the screw shaft 12, the friction body 04 rotates during movement, and generates sliding friction with the inner side of the housing 02, thereby generating current.
The elastic member 33 is a spring. As can be seen from the above structure, when the wave floats, the buoy 34 is driven to move up and down, and the up and down movement of the buoy 34 compresses or stretches the spring; the elastic member 33 is a spring having a large elastic deformation capability.
The float 34 is plastic. From the above construction, the plastic float 34 is lightweight, corrosion resistant, and easy to process and form, for example, high density polyethylene or polyvinyl chloride may be used for the plastic material.
