The rotating first bevel gear 10 applies a torsional force to the torsion spring 11, so that the torsion spring 11 is torsionally deformed. When the first bevel gear 10 rotates, it drives the second bevel gear 12 to rotate through the bevel teeth thereon, and further The threaded rod 13 is driven to rotate, thereby driving the cooling fan 16 thereon to move upward, and the torsion spring 11 twists and rebounds, driving the first bevel gear 10 and the second bevel gear 12 to rotate, and driving the cooling fan 16 to move downward, so that the cooling fan 16 dissipates heat to the PLC control cabinet body 2 up and down, which can effectively increase the air flow in the control cabinet, so that the heat in the cabinet can be quickly and evenly dissipated, thereby avoiding overheating of the equipment and improving the stability and reliability of the equipment.

[0045] The drive motor 5 is started, and the output end of the drive motor 5 rotates to drive the sector gear 8 to rotate, and further drives the first bevel gear 10 meshing therewith to rotate. The rotating first bevel gear 10 applies a torsional force to the torsion spring 11, so that the torsion spring 11 is twisted and deformed. When the first bevel gear 10 rotates, it will drive the second bevel gear 12 to rotate through the bevel teeth thereon, and further drive the threaded rod 13 to rotate, thereby driving the cooling fan 16 thereon to move upward, and the torsion spring 11 torsional rebounds, driving the first bevel gear 10 and the second bevel gear 12 to rotate, and driving the cooling fan 16 to move downward, so that the cooling fan 16 reciprocates up and down to dissipate heat to the PLC control cabinet body 2, which can effectively increase the air flow in the control cabinet, so that the heat in the cabinet can be quickly and evenly dissipated, thereby avoiding overheating of the equipment and improving the stability and reliability of the equipment.
