DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] During the long-term operation of the explosion-proof low-voltage withdrawable switch cabinet, it is necessary to regularly withdraw the drawer 3 to maintain or replace the electrical components inside the drawer 3. The traditional explosion-proof low-voltage withdrawable switch cabinet requires manual pulling by personnel to achieve the entry and exit of the drawer 3. During the manual pulling process, it is often impossible to control the force of pulling the drawer 3, resulting in the drawer 3 being very easy to collide with the inside of the cabinet body 1 during the pulling or pushing process, thereby causing the drawer 3 to vibrate. Over time, it will seriously affect the normal operation of the electrical components inside the drawer 3.

[0024] Embodiment 1: Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an explosion-proof low-voltage withdrawable switch cabinet, comprising a cabinet body 1, wherein a plurality of partitions 2 are fixedly arranged on the inner wall of the cabinet body 1 at equal intervals, wherein the width of the partition 2 is smaller than the width of the inner walls on both sides of the cabinet body 1, so as to facilitate the overall air circulation inside the cabinet body 1.

[0025] A drawer 3 is slidably provided on the upper surface of the partition 2. The drawer 3 is a U-shaped structure with two openings, which is convenient for rapid dissipation of heat inside the drawer 3 and for heat dissipation treatment thereof.

[0026] A rectangular opening matching the drawer 3 is provided on the front of the cabinet 1, and a driving mechanism 4 for driving the drawer 3 to automatically move in and out is provided on the upper surface of the partition 2;

[0027] The driving mechanism 4 includes a rectangular groove 401 opened on the upper surface of the partition 2, and a threaded column 402 rotatably arranged on the inner wall of the rectangular groove 401, and a motor 403 for driving the threaded column 402 to rotate is arranged on the back of the cabinet 1. The driving mechanism 4 also includes a Z-shaped plate 404 slidably arranged on the inner wall of the rectangular groove 401, and the back of the drawer 3 is fixedly connected to the front of the Z-shaped plate 404.

[0028] Two symmetrical limiting slide bars 405 are fixedly provided on the inner wall of the rectangular groove 401 , and the surface of the Z-shaped plate 404 is respectively provided with threaded holes threadedly connected to the outer surface of the threaded column 402 , and sliding holes slidably connected to the outer surfaces of the two limiting slide bars 405 .

[0029] Two symmetrical contact switches 406 corresponding to the Z-shaped plate 404 are fixedly disposed on the inner bottom wall of the rectangular groove 401 , and both contact switches 406 are electrically connected to the motor 403 via wires.

[0030] In this embodiment, by providing a driving mechanism 4, during actual use of the explosion-proof low-voltage switch cabinet, when it is necessary to pull out the drawer 3 in the switch cabinet for maintenance, the rotation of the motor 403 can drive the threaded column 402 to rotate, and the rotation of the threaded column 402 drives the Z-shaped plate 404 to move. The movement of the Z-shaped plate 404 drives the drawer 3 to automatically and slowly move out from the interior of the cabinet 1, thereby achieving the purpose of automatically moving the drawer 3 out of the cabinet 1. After the maintenance is completed, it is only necessary to drive the motor 403 in reverse to achieve automatic and slow entry into the cabinet 1. Moreover, when the Z-shaped plate 404 contacts the contact switch 406, the contact switch 406 will automatically control the motor 403 to turn off, thereby avoiding collision and vibration between the drawer 3 and the interior of the cabinet 1, thereby effectively solving the defect in the prior art that the drawer 3 cannot be automatically and stably pulled out.

[0035] A plurality of air nozzles 604 are equidistantly embedded on the outer surface of the vertical air pipe 602 , and the air outlet end of the heat dissipation fan 601 extends to the interior of the horizontal air pipe 603 .

[0036] In this embodiment, by providing a heat dissipation mechanism 6, the explosion-proof low-voltage switch cabinet can, during actual operation, transport the airflow into the horizontal air duct 603 and the vertical air duct 602 under the action of the heat dissipation fan 601, and use a number of nozzles 604 on the vertical air duct 602 to blow air to the sides of a number of drawers 3 for heat dissipation, thereby achieving the purpose of precise heat dissipation of each drawer 3, thereby effectively improving the heat dissipation efficiency, and the provision of the two side door panels 5 facilitates the operator to carry out wiring inside the cabinet 1, and is highly practical.
