However, this cooling device cannot automatically adjust the ventilation volume according to the temperature inside the cabinet, and the cooling fan's blowing angle is not adjustable, resulting in uneven heat dissipation of the switchgear inside the cabinet and affecting the cooling effect.

The rotating ring 19 is slidably installed at the bottom of the annular slide rail 18. Each of the connecting plates 17 has a strip-shaped hole 20. Several fixed round rods 21 are evenly installed on the outer surface of the rotating ring 19. The front ends of the fixed round rods 21 are movably inserted into the corresponding strip holes 20; a push rod 22 is fixedly installed on one side of the rotating ring 19, and an electric push rod 23 is hinged to the upper end of the cabinet 1, with the telescopic end of the electric push rod 23 hinged to the push rod 22; a spring 24 is connected between the sliding block 10 and the fixed frame 3, and a guide groove 25 is opened at the upper end of the swing frame 6, with the left end of the push frame 6 slidably installed in the guide groove 25 through the guide block 26; the rear end of the drive shaft 5 is connected to the transmission shaft 12 through the transmission belt 27, and the front end of the drive shaft 5 is connected to the rotating shaft 7 through the bevel gear set 28.
[0024] The working principle of this implementation plan is as follows: The electrical equipment used by the switchgear is controlled by an external controller. The heat dissipation mechanism and the ventilation mechanism are located at the upper part of the cabinet 1. The cabinet 1 is used to install the switchgear.
[0025] During heat dissipation: The fixed frame 3 is installed at the upper end of the cabinet 1. The drive motor 4 is horizontally installed on the left rear end of the fixed frame 3, with its rotating end movably inserted into the fixed frame 3 via a fastening bearing. The drive shaft 5 is installed on the rotating end of the drive motor 4. The swing frame 6 is movably installed on the left front end of the fixed frame 3, with a circular hole at its center corresponding to the drive shaft 5. The rotating shaft 7 is movably inserted into the bottom of the swing frame 6 via a fastening bearing. Several cooling fan blades 8 are evenly installed at the bottom of the rotating shaft 7. A set of round rods 9 are installed on the upper end of the fixed frame 3. Sliding blocks 10 are slidably installed on a set of round rods 9. On the round rod 9, the pusher frame 11 is mounted on the front end of the sliding block 10. The drive shaft 12 is movably inserted into the right side of the fixed frame 3 via a fastening bearing. The rotating rod 13 is mounted on the front end of the drive shaft 12 and fits against the pusher frame 11. A spring 24 connects the sliding block 10 and the fixed frame 3. A guide groove 25 is opened at the upper end of the swing frame 6. The left end of the pusher frame 6 is slidably mounted in the guide groove 25 via a guide block 26. The rear end of the drive shaft 5 is connected to the drive shaft 12 via a drive belt 27. The front end of the drive shaft 5 is connected to the rotating shaft 7 via a bevel gear set 28. Figure 4 — Figure 7 As shown, the drive motor 4 first drives the rotating shaft 7 to rotate several cooling fan blades 8 at the bottom through the drive shaft 5 and the bevel gear set 28 to dissipate heat from the switch equipment inside the cabinet 1. At the same time, the drive shaft 5 drives the rotating rod 13 to rotate counterclockwise through the transmission belt 27 and the transmission shaft 12. The rotating rod 13 pushes the push frame 11 back and forth. The spring 24 plays a reset role. The push frame 11 drives the push frame 6 to deflect back and forth to the right through the guide block 26, so that the several cooling fan blades 8 swing and blow air, making the heat dissipation of the switch equipment inside the cabinet more uniform.
[0026] During ventilation: A circular cylinder 14 is fixedly inserted into the upper end of the cabinet 1. Several rotating shafts 15 are evenly inserted into the outer surface of the circular cylinder 14. Several ventilation fan blades 16 are installed at the inner ends of the rotating shafts 15. A fixed block is installed at the center of the circular cylinder 14. The inner ends of the ventilation fan blades 16 are movably connected to the fixed block via rotating shafts. Several connecting plates 17 are installed at the outer ends of the rotating shafts 15. A circular slide rail 18 is installed at the upper end of the outer surface of the cabinet 14. A rotating ring 19 is slidably installed at the bottom of the circular slide rail 18. Several connecting plates 17 have slotted holes 20.

A push rod 22 is fixedly installed on one side of the rotating ring 19. An electric push rod 23 is hinged to the upper end of the cabinet 1, and the telescopic end of the electric push rod 23 is hinged to the push rod 22. Figure 2 and Figure 3As shown, a temperature sensor is installed on the inner wall of one side of the cabinet 1 to detect the temperature inside the cabinet 1. When the temperature is too high, the telescopic end of the electric push rod 23 retracts, which drives the rotating ring 19 to deflect clockwise through the push rod 22. Through several fixed round rods 21 and several connecting plates 17, several rotating shafts 15 are driven to rotate, thereby causing several ventilation fan blades 16 to deflect, achieving the purpose of ventilation. The ventilation volume can be adjusted by controlling the telescopic length of the electric push rod 23, making it convenient to use.
