The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the present invention provides a wind turbine generator system, including: a main shaft 1; the inertia flywheel 4 is fixedly connected to the outer side wall of the main shaft 1 and rotates along with the same rotating shaft of the main shaft 1; the generator 5 and the gearbox 6 are connected, and a rotor shaft of the generator 5 is in transmission connection with the main shaft 1 through the gearbox 6.
The inertia flywheel 4 is fixedly connected to the outer side wall of the main shaft 1 and rotates along with the same rotating shaft of the main shaft 1; the inertia flywheel 4 is used for storing energy and regulating speed, when the wind speed is high, the wind power drives the inertia flywheel 4 to accelerate, and a part of energy is stored in the inertia flywheel 4 in a kinetic energy mode; when the wind power is weak, the kinetic energy stored in the inertia flywheel 4 can still drive the generator 5 to generate electricity; the inertia principle is utilized to store energy through the inertia flywheel 4 with proper mass, and the rotating speed of the main shaft 1 can be automatically stabilized within a certain range.
The inertia flywheel 4 is fixedly connected with the main shaft 1, so that the risk of falling off of the inertia flywheel 4 and the main shaft 1 during synchronous rotation is prevented, and in order to further ensure the connection stability between the inertia flywheel 4 and the main shaft 1, preferably, the inertia flywheel 4 is a circular ring, the inner wall of the inertia flywheel 4 is provided with a ratchet 41, and correspondingly, the outer side wall of the main shaft 1 is provided with a plurality of pawls 11; the ratchet 41 teeth cooperate with the pawl 11.
As shown in fig. 2, further, in order to ensure that the inertia flywheel 4 achieves a better energy storage and speed regulation effect, centrifugal balancing weights 7 are installed on the top surface and the bottom surface of the inertia flywheel 4, the number of the centrifugal balancing weights 7 is three and are uniformly arranged, a first installation hole 71 is formed in the top position of each centrifugal balancing weight 7, and a second installation hole 72 is formed in the middle position of each centrifugal balancing weight 7; two ends of the return spring 8 are fixedly connected in the first mounting hole 71 and the second mounting hole 72 of the adjacent centrifugal balancing weight 7.
When the wind power meets the sudden wind speed and changes greatly, the centrifugal balancing weight 7 deviates from the axis of the main shaft 1 under the action of centrifugal force, so that the inertia of the inertia flywheel 4 is increased, the rotating speed of the main shaft 1 is automatically stabilized within a certain range, the fluctuation of the output electric energy of the generator 5 caused by the fluctuation of the wind power is stabilized, and the quality of the electric energy is improved.
Two ends of the reset spring 8 are fixedly connected in the first mounting hole 71 and the second mounting hole 72 of the adjacent centrifugal balancing weight 7; a relatively stable system is formed among the three centrifugal balancing weights 7 through the return spring 8, and when the wind power change amplitude is overlarge, tail positions 73 of the three centrifugal balancing weights 7 synchronously move outwards and deviate from the axis of the main shaft 1; when the wind power change amplitude becomes smaller, under the effect of the resilience force of the return spring 8, the tail parts 73 of the three centrifugal balancing weights 7 synchronously move inwards and are close to the axis of the main shaft 1, and the relative positions of the centrifugal balancing weights 7 and the axis of the main shaft 1 are determined according to the change amplitude of the wind power.

Further, the gearbox 6 can also increase the rotating speed of the rotor shaft of the generator 5, so as to improve the working efficiency of the generator 5, and the diameter of the first gear 62 is greater than that of the second gear 63, so that the rotating speed of the intermediate shaft 66 is greater than that of the main shaft 1, and the speed is increased for the first time; the diameter of the third gear 64 is larger than that of the fourth gear 65, the rotating speed of the rotor shaft is larger than that of the intermediate shaft 66, and the speed is increased for the second time; after the two times of speed increase, the rotating speed of the rotating shaft of the generator 5 is greatly improved, the working efficiency of the generator 5 is improved, and the technical problem that the generator 5 cannot generate electricity due to too small wind power is well solved.
Furthermore, the wind generating set also comprises a fan blade which is fixedly connected to the outer side wall of the main shaft, and the wind blows the fan blade to rotate so as to drive the main shaft 1 to rotate to complete the power generation process; preferably, the fan blades are in a plurality of pairs; the plurality of pairs of fan blades are arranged at equal intervals, and the stability of the main shaft 1 in the rotating process is improved through the equidistant arrangement; and a plurality of groups of fan blades are arranged, so that the utilization rate of wind energy is increased.
