As shown in fig. 7, in comparative example one, another embodiment of the present invention is: the surface of the mounting frame 7 is fixedly provided with a heat conducting pipe 30, and the surface of the heat conducting pipe 30 is provided with a group of outlets 31; when the brake piece 8 carries out friction braking to the brake sleeve 4, the generated heat can enter the heat conduction pipe 30 and blow to the brake sleeve 4 along the outlet 31, so that the brake sleeve 4 is in a dry state, and the friction coefficient reduction caused by the wetting of the brake sleeve 4 is avoided.
Working principle: when the detecting mechanism detects that the rotating speed of the rotating shaft 3 of the generator main body 2 is too high, the brake piece 8 immediately extrudes onto the brake sleeve 4 to brake the rotating shaft 3, when the brake piece 8 brakes the brake sleeve 4 for a period of time, the control module starts the driving motor 5, the output end of the driving motor 5 drives the threaded rod 6 to rotate for a plurality of times, the threaded rod 6 can drive the mounting frame 7 to slide on the positioning rod 9 for a distance when rotating, so that the brake piece 8 and the brake sleeve 4 are relatively displaced, the brake piece 8 is contacted with the brake sleeve 4 which is not worn in the next braking process, and thus good braking capability is maintained, and the control module can change the positions of the mounting frame 7 and the brake piece 8 for a plurality of times, so that the braking capability of the braking device can be improved; when the threaded rod 6 drives the mounting frame 7 to approach the driving motor 5, the rotating wheel 11 on the surface of the mounting rod 10 is contacted with the threaded rod 6 and rotates, the rotating wheel 11 drives the extrusion rod 14 to extrude the air bag 13, air in the air bag 13 enters the storage box 12 along with the air, the pressure in the storage box 12 is increased to enable lubricating oil to flow out along the guide pipe 15 (the one-way valve is opened at the moment) and flow on the surface of the threaded rod 6, so that the mounting frame 7 keeps moving when passing through the threaded rod 6, after the extrusion rod 14 is far away from the air bag 13, the air inlet one-way valve is used for feeding air into the air bag 13, and the air bag 13 is restored to be in shape, so that lubricating oil drops on the threaded rod 6 once the mounting frame 7 moves; in the process that the mounting frame 7 moves on the threaded rod 6, the part of the threaded rod 6 smeared with lubricating oil can enter the mounting frame 7, and the smearing brush 17 can smear the lubricating oil on the threaded rod 6 uniformly, so that the lubricating effect of the lubricating oil is improved;
when wind power drives the fan blade 1 and the rotating shaft 3 to rotate, when the rotating speed of the rotating shaft 3 is too high, the centrifugal force of the rotating shaft 3 drives the pressing plate 20 to move and stretch the spring 19, and when the pressing plate 20 presses the pressure switch 21, the brake piece 8 is started to brake the brake sleeve 4, so that the rotating shaft 3 can be braked rapidly and accurately, and the generator main body 2 is protected; when the mounting frame 7 moves to the driving motor 5, the rosin block 24 rubs and is smeared on the surface of the brake sleeve 4, so that the friction force of the surface of the brake sleeve 4 is improved, the braking effect is further improved, and the elastic ring 23 can enable the rosin block 24 to always prop against and rub against the brake sleeve 4; when the generator main body 2 is used, the heat dissipation motor 25 is started, the heat dissipation motor 25 drives the fan blades 26 to rotate, and when the fan blades 26 rotate, air flow is driven to blow to the brake piece 8, so that the temperature of the brake piece 8 and the generator main body 2 is reduced, the excessive temperature of the brake piece 8 is avoided, meanwhile, the excessive temperature in the generator main body 2 can be avoided, when the air flow moves in the generator main body 2, the rotating plate 27 is driven to rotate and open, the air flow absorbing heat is discharged into the generator main body 2, and the safety of equipment in use is improved; the collecting piece 28 can collect rainwater in the daily use process, the collecting piece 28 can cool the generator main body 2 after being full, water in the collecting piece 28 can enter the connecting pipe 29, and when the air flow of the fan passes through the connecting pipe 29, the air flow can be cooled, so that the cooling effect on the inside of the generator main body 2 and the brake piece 8 is improved;
the spiral connecting pipe 29 can uniformly cool the air flow generated by the passing fan blades 26, so that the cooling effect is improved; part of lubricating oil which lubricates the threaded rod 6 is easy to drop on the inner bottom wall of the generator main body 2, and when the mounting frame 7 moves, the wiping sponge 32 can be driven to wipe the inner bottom wall of the generator main body 2, so that on one hand, the low-drop lubricating oil can be wiped off, on the other hand, the inner bottom wall of the generator main body 2 can be wiped off, dust and impurities can be wiped off, and when the generator main body 2 is maintained, the wiping sponge 32 can be replaced and cleaned; when the brake piece 8 carries out friction braking to the brake sleeve 4, the generated heat can enter the heat conduction pipe 30 and blow to the brake sleeve 4 along the outlet 31, so that the brake sleeve 4 is in a dry state, and the friction coefficient reduction caused by the wetting of the brake sleeve 4 is avoided.
