Detailed Description
The method principle of the present invention will be described in detail below with reference to the accompanying drawings.
When the wind speed sensor 8 senses that the wind speed is lower than 3 meters per second, the grid-connected condition is not reached, the sensor 8 outputs a current signal to the frequency converter 10, the frequency converter 10 drives the servo motor 13 to operate, and further, the servo motor 13 controls the lifting platform 14 to ascend until the bevel gears 16 are meshed with each other for transmission, so that the generator G2 generates electricity.
Meanwhile, the hydraulic device driven by the servo motor 11 controls the connecting rod 9 to move backwards, so that the generator 7 is driven to move backwards by 1.5m along the sliding groove 12.
In this phase, the generator 15 charges the accumulator 17 via a rectifier, supplying the various types of loads.
When the wind speed sensor 8 senses that the wind speed is higher than 3 meters per second, a grid-connected condition is achieved, the sensor 8 outputs a current signal to the frequency converter 10, the frequency converter 10 drives the servo motor 13 to operate, and further, the servo motor 13 controls the lifting platform 14 to descend until the bevel gear 16 is separated, so that the generator 15 stops generating electricity.
