The middle part of the partition 50 is penetrated by a thick wind tube 47, and the large fan device 46 is arranged inside the thick wind tube 47.

[0044] The small wind section 49 includes a unit T-plate 51, a fan shaft 52, a small fan 53, a one-way valve 54 and a thin wind tube 55.

The small fan 53 is distributed inside the thin wind tube 55. The fan shaft 52 is fixed in the middle of the small fan 53. A one-way valve 54 is fixed in the thin wind tube 55 below the small fan 53. Fig.15 The one-way valve 54 is a one-way air-passing valve in the prior art. After the small fan 53 rotates, the airflow in the fine air tube 55 impacts the one-way valve 54 downward, and then the one-way valve 54 is opened for ventilation. After the small fan 53 stops rotating, the one-way valve 54 automatically closes to prevent air backflow.

[0045] The bridge assembly 13 includes an inner control shaft 56, a drive shaft 57, a flat T-plate 58, a bridge shaft 59, a follower shaft 60 and an outer control shaft 61. The flat T-plate 58 is fixed on the fine air tube 55. The flat T-plate 58 supports and positions the inner control shaft 56, the drive shaft 57, the follower shaft 60 and the outer control shaft 61. An outer gear ring is fixed on the rotating fan on the bridge assembly 13, and the outer gear ring is connected to the gear meshing transmission fixed at one end of the inner control shaft 56. One end of the drive shaft 57 is connected to the annular bevel gear fixed on the inner control shaft 56 through a fixed bevel gear. The drive shaft 57 and the follower shaft 60 are connected by a bridge shaft 59. One end of the follower shaft 60 is connected by meshing transmission with a fixed bevel gear and a ring bevel gear fixed on the external control shaft 61. One end of the external control shaft 61 is connected by meshing transmission with a fixed gear and an outer ring gear 48. The bridge shaft 59 is movably sleeved in a through hole opened on the translation frame 38. The bridge shaft 59 is connected by meshing transmission with a fixed cylinder gear and a disk gear fixed on the follower shaft 60, and the cylinder gear is connected by meshing transmission with the disk gear fixed on the drive shaft 57 through axial movement. Fig.16 It is understood that when the temperature in the power station box 1 is too high, it will automatically trigger the adjustment, and the subsequent transmission causes the translation frame 38 to translate, and then the translation frame 38 translates to the left to drive the bridge shaft 59, and the disc gear on the drive shaft 57 and the barrel gear on the bridge shaft 59 are meshed and connected. When the bridge group 13 is working and ventilated, the fan on the bridge group 13 rotates to drive the internal control small shaft 56, and then drives the translation frame 38 through the drive shaft 57, and then drives the follower shaft 60 through the bridge shaft 59, and then drives the outer ring gear 48 through the external control small shaft 61, and then controls the working ventilation of all small wind parts 49.

[0046] The power supply provided in the power station box 1 supplies power to the partition 11, and the partition 11 works to blow air, and the outside air is sucked into the upper chamber in the wind box 10, and then enters the lower chamber in the wind box 10 through the fine wind tube 55. The air flow diffuses downward into the power station box 1, and the air flows from top to bottom inside the power station box 1, and is finally discharged through the exhaust window 8. The power control instruments and equipment in the power station box 1 generate heat during operation, and the heat will be taken away by the flowing air. In addition, some air flows in from the bottom of the shunt pipe 16, and then rises and is discharged through the branch air holes 161. The heat in this part of the air flow will invade the deformation rod 15. If the air environment in the power station box 1 is overheated, the deformation rod 15 will be excessively thermally expanded and deformed. The deformation rod 15 stretches to support the gravity column 14, and the gravity column 14 rises and drives the pressure timing machine Structure 6, specifically, the L-shaped lifting plate 21 rises to drive the head shaft 24 to rotate, and then drives the ring plate gear 22 through the one-way bearing 23, and then the waist shaft 25 rotates to drive the worm 26, and then drives the range extender gear 18 to rotate through the tail shaft 27, thereby controlling the rotation of the boost shaft 32. The rotation of the boost shaft 32 causes the spring 31 to contract and store force. After the boost shaft 32 rotates a full circle, the force storage pressure of the spring 31 is greater than the positioning effect of the three-section plate frame 7 on the pressure ring plate 30. In this way, the pressure ring plate 30 will rotate a circle and then be stuck by the three-section plate frame 7 again. During the process of the pressure ring plate 30 rotating a circle, it is affected by the friction on the rubber arc plate 33 and rotates slowly. It takes a period of time for the pressure ring plate 30 to rotate a circle. During this period of time, the alarm light 3 is energized to alarm, and the ventilation is automatically enhanced in the bellows device 2.

[0047] During the rotation of the pressure ring plate 30, the three-section plate frame 7 is supported by the pressure ring plate 30 and translated. As mentioned before, the translation of the three-section plate frame 7 causes the circuit in the switch 4 to be unblocked, and then the alarm light 3 is powered and works. In addition, the translation of the three-section plate frame 7 drives the translation frame 38. After the translation frame 38 translates, the transmission path in the bridge group 13 is established, and then the outer ring gear 48 rotates to drive all the fan shafts 52, thereby controlling the rotation of the small fan 53. In this way, multiple blowing mechanisms are established on the partition 11, and the bellows device 2 automatically strengthens the blowing of the power station box 1 to cope with the problem of rising temperature inside the power station box 1. When the temperature inside the power station box 1 is normal, the bellows device 2 will not strengthen the blowing, that is, the small fan 53 will not rotate. The energy supply mechanism of the rotation source of the small fan 53 is the motor part on the large fan device 46. The fan speed on the large fan device 46 remains unchanged. If multiple small fans 53 are driven additionally, the workload of the motor will increase. Therefore, only when the temperature inside the power station box 1 is too high, it will automatically adjust to make the small fan 53 temporarily rotate.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
