4. A power plant according to claim 3, characterized in that the surface of the reinforced concrete pier (101) is coated with an epoxy coating to prevent seawater erosion, and the fixing support (102) is made of nickel-based alloy.
5. The power generation device according to claim 1, characterized in that the tilt sensor (303) is a SINDT type tilt sensor.
6. A method of generating electricity using the power generation apparatus of any one of claims 1-5, comprising the steps of:
When the angle of the cross rotating in a certain direction exceeds 45+/-5 degrees, the inclination sensor sends out a signal, the control system cuts off the magnetic coupling at one side of the second power generation part, turns on the magnetic coupling at one side of the first power generation part, and the first power generation part generates power;
When the angle of the cross rotating towards a certain direction is not more than 45+/-5 degrees, the inclination sensor sends out a signal, the control system cuts off the magnetic coupling on one side of the first power generation part, turns on the magnetic coupling on one side of the second power generation part, converts the swing of the shell into the rotation of the small steel wheel (405) in a single direction through the escapement mechanism, stores and releases energy through the spring mechanism, the spring shaft is prevented from reversing by the anti-reversing mechanism in the energy storage process, and the spring mechanism drives the bevel gear (409) to rotate, so that the power generation of the second power generation part is realized.
