In the present embodiment, the power generating mechanism 101 is provided at a central portion of the floating body 13. The power generating mechanism 101 includes a power generating mechanism housing 102 having a closed inner cavity, and the power generating mechanism housing 102 is a closed housing, and the power generating mechanism The other components of the 101 are disposed in the enclosed power generating mechanism housing 102, which further improves the sealing performance of the power generating mechanism 101 and improves reliability. The power generating mechanism 101 further includes a swinging bar 104. The inner cavity of the power generating mechanism housing 102 is provided with a transversely disposed beam 103. The swinging bar 104 and the beam 103 are arranged in a cross shape, and the intersection of the swinging bar and the beam 103 is rotated and supported by the rotating shaft. The swing lever and the beam 103 can be relatively oscillated about the rotation axis. The lower end of the swinging rod is fixed with a spherical weight 105.

Of course, it is not excluded that in other embodiments, the weight or the rail is provided at a position where the two are relatively matched to reduce friction. The rolling body supports the weight by the rolling elements.

Since the swing lever of the present invention is rotatably mounted in the floating body about a constant axis of rotation, as seen in Fig. 111, the swing link 104 is rotated about an axis perpendicular to the beam 103, preferably as shown in Figs. 12-13, 15-16. In the two embodiments shown, the support rails 1050 and the weights 105 are blocked in the direction of extension of the axis of rotation. In the embodiment shown in Figures 12-13, the weight 105 is spherical, and the support surface of the support rail 1050 is an annular curved surface that fits the lower side of the spherical weight, through the axis of rotation between the annular curved surface and the spherical surface.

And is limited by the limit beam on the front and rear sides. The floating body 13 is integrally sealed to seal the power generating mechanism 101 therein, and the power generating mechanism 101 is protected from water, dust, and impact.
