[0035] The power generation working principle of the application is as follows:

[0036] 1) In the application, the magnetic material 17 arranged on the surface of the guide rod 6 adopts a magnet. When the sleeve 15 rises and falls along with the circular platform 4 along the guide rod 6, the coil I 16 in the sleeve 15 cuts the magnetic material 17 on the guide rod 6 and generates electric energy.

When the circular platform 4 rises and falls, the hydraulic rod 5 is compressed, forcing the rack 18 to slide on the gear rack disc 7, thereby driving the gear 19 meshed therewith to rotate, rotating the generator 8 connected with the gear 19, cutting the magnetic induction lines to generate electric energy. The generated electric energy is converted by a power converter and transmitted to the power grid on the shore by a cable.

[0038] 3) A transmission device is arranged on the outside of the installation block 26. When the hydraulic rod 5 drives the rack 18 to slide along the radial direction of the gear rack disc 7, the rack 18 drives the magnetic steel 28 to extend into the coil II 27, as shown in the drawing, the reciprocating motion of the rack 18 makes the magnetic steel 28 generate magnetic induction lines in the coil 29 II to induce electromagnetic induction phenomenon and generate electricity.
