Abstract
The invention discloses a wave power generating device. The wave power generating device comprises a stator, a rotor and a vane wheel. An exciting winding wind around the stator, an armature winding is wound inside the rotor, and the vane wheel is arranged at the outermost position. The vane wheel, the rotor, pin rollers and spring ejector rods form an overrunning structure, wherein the pin rollers and spring ejector rods are arranged between the vane wheel and the rotor. Impact force of sea waves acts on blades of the vane wheel and pushes the blades to enable the vane wheel to rotate, then the rotor is driven to rotate through the overrunning device, and the armature winding rotates along with the rotor and cuts magnetic induction lines of a magnetic field to generate alternating-current induced electromotive force so that electricity can be output. According to the wave power generating device, the impact force of upward sea waves on the blades during fluctuation of the sea waves pushes the vane wheel to rotate, and the kinetic energy of the sea waves is converted into the kinetic energy of the vane wheel. The overrunning device is designed, so that the rotor rotates in one direction all the time, the design of the overrunning device guarantees that the rotating direction of the rotor is always fixed and the phase of generated currents is fixed, and the trouble of regulating the phase frequently is avoided; in addition, due to the fact that internal mechanisms move in a fixed direction all the time, the reliability of the device can be improved, and the service life of the device can be prolonged.
