[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment. The use of a control cabinet is inseparable from a heat dissipation mechanism. Industrial robots require matching control cabinets (such as KUKA robots require a corresponding KR C4 control cabinet).

[0003] After searching, a control cabinet heat dissipation mechanism disclosed in publication number CN219499886U includes a cabinet body and a cabinet door. The cabinet body and the cabinet door are used in combination. When the above product is in use, it solves the problem that the existing product cannot perform air blowing and heat dissipation at different positions inside the cabinet. When the protection effect of the air inlet is poor, impurities and foreign objects are easy to enter the cabinet. Therefore, a control cabinet heat dissipation mechanism is proposed. Utility Model Content

[0008] The ends of the curtains in the two shielding mechanisms are fixed to the top and bottom of the sliding frame respectively;

[0009] A driving mechanism is arranged on one side of the cabinet and is used to adjust the height of the sliding frame.

[0010] As a further scheme of the utility model, the driving mechanism includes two connecting blocks and two threaded rods, the two threaded rods are respectively rotatably connected to one side of the two second guide rails, the two connecting blocks are respectively fixed on both sides of the sliding frame, the two threaded rods are respectively threaded through the two connecting blocks, the circumference of the two threaded rods are fixedly connected with synchronous wheels, the two synchronous wheels are connected by a synchronous belt transmission, the top of one of the threaded rods is fixedly connected with a worm gear, the top of the cabinet is fixedly connected with a motor, one end of the motor output shaft is fixedly connected with a worm, and the worm is meshed with the worm wheel.

At the same time, the mounting shaft rotates to facilitate the curling and loosening of the curtain, and keeps it in a tensioned state under the action of the torsion spring, which is convenient for use. When the filter passes through one side of the brush plate, the filter can be cleaned by the brush plate, thereby improving the flexibility of use.

[0019] In the utility model, when the sliding frame is moving, the sliding frame drives the curtain to move synchronously on one side of the air inlet, thereby maintaining the shielding of the air inlet and preventing foreign matter from entering the cabinet. At the same time, when the filter passes through one side of the brush plate, the filter can be cleaned by the brush plate, thereby improving the flexibility of use.
