Furthermore, the spring 18 therein is in a compressed state, which provides compression for the end of the round shaft 16, improves the friction force, and can provide a friction limiting effect before and after the flipping.
[0031] Working principle: When the entire electrical control cabinet is in use, the fan 22 and the servo motor 12 are both connected to an external power supply and an external control switch for power supply and electrical control;
[0032] During daily use, the fan 22 is used to generate an outlet airflow for heat dissipation. The airflow is transported through the hard air pipe 10, the connecting hose 14 and the connecting hard pipe 6 in sequence, and the airflow enters the blowing hood 7, thereby providing heat dissipation blowing to the electrical components inside the electrical control cabinet body 1;
[0033] At the same time, the servo motor 12 drives the screw 20 to rotate, and the screw 20 and the nut 21 are threaded, and the guide function of the guide rod 3 and the guide sleeve 5 is cooperated to realize the vertical drive of the blower 22, and the blower cover 7 also moves with the blower 22, and moves vertically inside the electrical control cabinet body 1, so as to blow and dissipate air at various vertical positions inside the electrical control cabinet body 1, and ensure uniform blowing at various positions;

At the same time, the shielding belt 9 always shields the lateral through slot 2 to prevent dust from entering there, thereby playing a dust-proof role.
[0035] Furthermore, during the maintenance of the entire electrical control cabinet, by opening the cabinet door of the electrical control cabinet body 1, the interior of the electrical control cabinet body 1 is Figure 1As shown, the connecting hard tube 6 and the hard air tube 10 can be folded and flipped, which can avoid blocking the opening of the electrical control cabinet body 1 during internal maintenance, and facilitate the maintenance of the inner side of the electrical control cabinet body 1; the specific operation is as follows, by pulling the connecting hard tube 6, the circular shaft 16 and the sleeve 17 are relatively rotated, so that the connecting hard tube 6 is flipped about the hard air tube 10, so that the two are flipped 90°, and the connection between the two adopts a connecting hose 14, which will not affect the flipping due to its flexible design; after maintenance, the connecting hard tube 6 and the blowing hood 7 are reset by flipping again, and further the spring 18 therein is in a compressed state, providing pressure for the pressure plate 19, so that the pressure plate 19 presses the end of the circular shaft 16, and the friction between the pressure plate 19 and the circular shaft 16 is increased, which is used to provide the role of friction positioning, and avoids the connecting hard tube 6 and the hard air tube 10 from flipping due to vibration during daily heat dissipation, and ensures the stability of the blowing hood 7 during heat dissipation.
