the external wind to enter, and the spring 15 always stores the force, when wind power is weakened, the wind power is smaller than the elastic force of the spring 15, the spring 15 drives the filter plate 14 to move to the position of the brush blade plate 13 due to the self elastic force of the spring 15, at the moment, the fan blade 11 continues to rotate under inertia, the brush blade plate 13 also rotates, bristles on the surface of the brush blade plate 13 can clean filtered wastes on the surface of the filter plate 14 while rotating, after the fan blade 11 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the coil 6 to rotate in the magnet tube 7, the coil 6 performs cutting magnetic induction line motion in the magnet tube 7 to generate current so as to achieve the purpose of generating power, the generated current is output through the commutator 3 through the electric brush and the lead 31, the rotating shaft 4 continuously rotates and generates heat in the process of generating power, when the wind power is too large, the rotating speed of the rotating shaft 4 is accelerated or the rotating time of the rotating shaft 4 is too long, the heat can continuously increase, when the temperature reaches a certain value, the rotating shaft 4 and the generator 5 can generate deformation, the device is damaged to a certain extent, at the moment, the inner ring of a deep groove ball bearing 24 fixedly connected with the rotating shaft 4 is heated and transfers heat to the outer ring through a roller, evaporated liquid 25 in a U-shaped guide pipe 26 connected with the outer ring evaporates into gas when the heat reaches a certain value, the air pressure in the U-shaped guide pipe 26 is increased, a piston 27 at the other end of the U-shaped guide pipe 26 is pushed to move downwards, a friction block 29 is pushed by a piston rod 28 to move downwards to be in contact with the rotating shaft 4, the generated friction force can prevent the rotating shaft 4 from rotating and reduce the rotating speed of the rotating shaft 4, the device is protected, the memory alloy wire 18 is made of a CuZnAl memory alloy spring, the deformation temperature of the CuZnAl memory alloy is 75-80 ℃, the memory alloy wire 18 is preprocessed into a spring shape, and when the temperature of the outer ring of the deep groove ball bearing 24 reaches 80 ℃, the memory alloy wire 18 in a sliding cavity 33 is heated and deforms and stretches, the sliding plug 19 is pushed to slide, the sliding plug 19 drives the first contacts 20 to move, so that the two first contacts 20 are respectively contacted with the two second contacts 21, a circuit is further conducted, the alarm 23 is started, the alarm 23 emits light and sounds to remind an operator of timely maintenance, the semiconductor refrigerating sheet 32 arranged on the wall of the ventilation pipe 9 can cool the generator 5 and the interior of the generator 5 in work, when the coil 6 in the generator 5 rotates to start power generation, the temperature in the generator 5 can rise, after the semiconductor refrigerating sheet 32 is electrified, the temperature of one side of the semiconductor refrigerating sheet 32 can be reduced to cool the generator 5, the temperature of the other side can rise, air entering the cavity 2 of the device from the outside can pass through the ventilation pipe 9, the heat of the side, which generates heat, of the semiconductor refrigerating sheet 32 can be taken away, and the air is exhausted out of the casing 1 from exhaust openings on two sides of one end of the casing 1, when the external wind direction deviates from the direction opposite to the fan surface, and the wind speed is high enough, thrust is generated on the steering plate 12 at one end of the casing 1, so that the casing 1 is pushed to rotate, the fan blade 11 can be opposite to the wind direction, and the wind power is continuously utilized to generate electricity.
