The working principle is as follows: in the use process, when the wind speed is low, the second blade 4 rotates under the action of the wind to transmit power to the transmission shaft 5, the transmission shaft 5 drives the generator to generate electricity through the gearbox, the stress direction of the first blade 3 is the same as that of the second blade 4 at the moment, and the second electromagnet 19 attracts the lug 18, so that the first blade 3 also rotates under the action of the wind at the moment, the power is transmitted to the transmission shaft 5, the auxiliary power for generating electricity is provided, and the efficiency of the equipment is improved; when the wind speed is increased, the rotating speeds of the first blade 3 and the second blade 4 are simultaneously increased, and the temperature in the rotating cabin 2 is gradually increased; the gas in the air bag 10 is expanded by heating, one end of the air bag 10 extends outwards along the end of the air bag shell 8 with the opening, when the temperature in the rotary cabin 2 reaches the preset temperature, the air bag 10 is abutted with the contact switch 9, the contact switch 9 is opened, the second electromagnet 19 is closed and does not attract the lug 18 any more, the third electromagnet 20 is opened and attracts the lug 18, and because the lug 18 is fixedly connected with the first blade shaft 15, therefore, when the third electromagnet 20 attracts the bump 18, the first blade shaft 15 also rotates 180 degrees at the same time, at this time, the stress direction of the first blade 3 is opposite to that of the second blade 4, the reaction force of the first blade 3 in one rotation direction can be given to the transmission shaft 5 under the action of wind, and the resistance of the rotation of the transmission shaft 5 prevents the rotation speed of the second blade 4 from being accelerated continuously, and the phenomenon that the temperature in the rotary cabin 2 is too high due to the long-time work of a mechanical brake when the wind speed is high for a long time is avoided.
When the first blade 3 rotates under the action of wind, the trend is towards the direction of the rotating cabin 2 to generate horizontal displacement, at the moment, the first blade 3 drives the first blade shaft 15 and the first blade shaft sleeve 16 to rotate along the transmission shaft 5, because the first blade shaft sleeve 16 is fixedly connected with the first blade base 11, the first blade base 11 also moves horizontally, when the first blade base 11 slides horizontally, the first blade base 11 is firstly abutted against the first roller 22 and then abutted against the second roller 27, therefore, when the first blade base 11 moves towards the rotating cabin 2 and is abutted against the first roller 22, the first blade base 11 drives the first roller 22 to rotate, and simultaneously pushes the first roller 22 towards the rotating cabin 2, the first roller 22 pushes the first push plate 25 through the first rotating shaft 23 and the fourth first connecting rod 24, the first push plate 25 pushes the support rod 30 towards the rotating cabin 2, and because the other end of the support rod 30 is abutted against the sliding block 7, the support rod 30 is prevented from moving, so that the first blade 3 cannot be displaced in the horizontal direction;
when the air bag 10 is abutted against the contact switch 9, the first electromagnet 6 is also switched on, the first electromagnet 6 attracts the sliding block 7, and the sliding block 7 slides upwards to be separated from the contact state with the supporting rod 30; when the wind power is continuously increased, the thrust in the horizontal direction borne by the first blade 3 is increased, the first blade 3 drives the first blade shaft 15, the first blade shaft sleeve 16 and the first blade base 11 to move towards the rotating cabin 2 along the horizontal direction, the first blade base 11 pushes the first roller 22 towards the rotating cabin 2, the first roller 22 pushes the first push plate 25 through the first rotating shaft 23 and the first connecting rod 24, and the first push plate 25 pushes the return spring 33 and pushes the supporting rod 30 at the same time; when wind power is increased to a preset degree, the first blade base 11 is moved to abut against the second roller 27, the second roller 27 pushes the second push plate 32 along the horizontal direction through the second rotating shaft 28 and the four second connecting rods 29, the second push plate 32 moves towards the direction close to the rotating cabin 2 to extrude the spring switch 26, the spring switch 26 is enabled to be opened, the spring switch 26 controls the steering motor 14 to work, the steering motor 14 drives the rotating cabin 2 to integrally rotate, the first blade 3 and the second blade 4 are enabled to face the wind direction, the stress area of the first blade 3 and the stress area of the second blade 4 are reduced, the rotating speed is reduced, the temperature in the rotating cabin 2 is reduced, and the service life of the equipment is prolonged.
When the temperature in the rotating cabin 2 is reduced to a normal level, the air bag 10 is not contacted with the contact switch 9 any more, the third electromagnet 20 is closed, the second electromagnet 19 is opened and attracts the lug 18, so that the lug 18 drives the first blade shaft 15 to rotate 180 degrees, the stress direction of the first blade 3 is the same as that of the second blade 4, and the efficiency of the equipment is improved.
