A positioning groove 5221 corresponding to the positioning protrusion 522 is provided on the side of the top support frame 434 away from the rotating groove 512. The top of the positioning protrusion 522 extends out of the top end of the positioning longitudinal tube 52 and is movably engaged in the positioning groove 5221. By setting the positioning protrusion 522, the top of the positioning protrusion 522 extends out of the top end of the positioning longitudinal tube 52 and is movably engaged in the positioning groove 5221, so as to fix the rotating mechanism 5 and the inner slide 43, and the control panel 71 can be detachably mounted on the rotating longitudinal frame 51.

When the cabinet door body 2 is closed, the control panel 71 is movably connected in the corresponding cabinet door groove 201, which is convenient for the use of the control panel 71. When the cabinet door body 2 is opened and closed, the control panel 71 is separated from the cabinet door groove 201, which does not affect the electrical connection between the control panel 71 and the electrical equipment 7. The subsequent translation and sliding out of the inner sliding device 3 does not affect the electrical connection between the control panel 71 and the electrical equipment 7.

[0044] A longitudinal pull rod 53 is fixedly installed at the bottom end of the positioning protruding rod 522, and the longitudinal pull rod 53 is movably connected to the positioning longitudinal tube 52. A horizontal pull handle 54 is vertically installed at the bottom of the longitudinal pull rod 53. A longitudinal slide groove 541 is opened in the middle of the positioning longitudinal tube 52. The horizontal pull handle 54 is slidably connected to the longitudinal slide groove 541. A horizontal limit groove 542 is vertically opened at the bottom of the longitudinal slide groove 541. When it is necessary to rotate and open the rotating mechanism 5 to inspect the electrical equipment 7 on the inner sliding mechanism 4, the hand The horizontal pull handle 54 is held and moved downward to drive the longitudinal pull rod 53 to move downward. The horizontal pull handle 54 slides in the longitudinal slide groove 541 until it slides to the position of the horizontal limit groove 542. Then, the horizontal pull handle 54 is rotated and the horizontal pull handle 54 is locked into the horizontal limit groove 542 for limiting the position. The longitudinal pull rod 53 moves downward to drive the positioning protrusion 522 to move downward. The top of the positioning protrusion 522 disengages from the positioning groove 5221, and the rotating longitudinal frame 51 loses its positioning, making it easy to rotate the entire rotating longitudinal frame 51 to open the rotating longitudinal frame 51.

[0045] A buffer pad 55 is fixedly installed at the bottom of the second vertical frame 433, and the bottom of the rotating vertical frame 51 contacts the buffer pad 55. By providing the buffer pad 55, when the rotating vertical frame 51 is closed, the bottom of the rotating vertical frame 51 contacts the buffer pad 55 for buffering.

[0046] The heat dissipation mechanism 6 includes a heat dissipation bracket 61, a ventilation slot 101 is provided at the bottom of the side end of the cabinet frame 1, the heat dissipation bracket 61 is fixedly connected to the ventilation slot 101 by bolts, a plurality of heat dissipation fans 611 are fixedly installed on the heat dissipation bracket 61, and a dustproof ventilation frame 612 is fixedly provided on the outside of the ventilation slot 101; the inner filter element 8 includes a U-shaped bracket 81, the U-shaped bracket 81 is fixedly installed at the bottom of the first longitudinal frame 432 and the second longitudinal frame 433, and a ventilation inner filter frame 82 is detachably installed in the U-shaped bracket 81, the position of the ventilation inner filter frame 82 corresponds to the position of the ventilation slot 101, and the side of the ventilation inner filter frame 82 away from the U-shaped bracket 81 is in contact with the inner wall of the cabinet frame 1. During the use of the high and low voltage control cabinet, a plurality of heat dissipation fans 611 can be controlled to be turned on, and the external airflow is dust-proofed by the dustproof ventilation frame 612, and then secondary filtered by the ventilation inner filter frame 82, so as to further prevent impurities in the external airflow from being introduced into the cabinet frame 1 to affect the electrical equipment 7, thereby improving the use effect of the electrical equipment 7 in the entire high and low voltage control cabinet;

[0047] When the inner slide 43 is controlled to slide out of the cabinet frame 1 , the U-shaped bracket 81 and the ventilation inner filter frame 82 slide out, making it easy to disassemble and replace the ventilation inner filter frame 82 .

[0048] Working principle: During the use of the high and low voltage control cabinet, multiple cooling fans 611 can be turned on by controlling, and the external airflow passes through the dustproof ventilation frame 612 for dust prevention treatment, and then passes through the ventilation inner filter frame 82 for secondary filtration, which further prevents impurities in the external airflow from being introduced into the cabinet frame 1 to affect the electrical equipment 7, thereby improving the use effect of the electrical equipment 7 in the entire high and low voltage control cabinet;

[0049] When maintenance is needed, the cabinet door 2 can be rotated to open, and then the positioning longitudinal tube 52 is held and pulled outward to pull the rotating mechanism 5. Since the rotating mechanism 5 and the inner slide 43 are fixed, the inner slide 43 is synchronously moved out of the cabinet frame 1, and at the same time, the transmission gear 47 is driven to move out. At this time, the transmission gear 47 can be meshed and connected with the transmission rack 471, and the transmission rack 471 can drive the transmission gear 47 to rotate, thereby driving the driving worm 461 to drive the driven worm gear 46 and the rotating horizontal shaft 441 to rotate, and then the roller frame 45 can be controlled to rotate, so that the auxiliary roller 451 rotates and makes the auxiliary roller 451 contact with the ground, so as to provide roller support for the end of the inner slide 43 away from the bottom slide seat 421, thereby improving the stability of the inner slide 43 moving out in translation;

[0050] Since the inner slide 43 can be easily slid out of the cabinet frame 1, it is convenient to subsequently inspect and disassemble the electrical equipment 7 on the inner slide 43, without having to go deep into the cabinet frame 1 to inspect the electrical equipment 7, which is simple and convenient, and improves the inspection efficiency of the high and low voltage control cabinet;

[0051] When it is necessary to rotate and open the rotating mechanism 5 to inspect the electrical equipment 7 on the inner sliding mechanism 4, the horizontal pull handle 54 is held and moved downward to drive the longitudinal pull rod 53 to move downward, and the horizontal pull handle 54 slides in the longitudinal sliding groove 541 until it slides to the position of the horizontal limit groove 542. Then, the horizontal pull handle 54 is rotated, and the horizontal pull handle 54 is clamped in the horizontal limit groove 542 to limit the position. The longitudinal pull rod 53 moves downward to drive the positioning protrusion 522 to move downward, and the top of the positioning protrusion 522 is separated from the positioning groove 5221, and the rotating longitudinal frame 51 loses its position, which makes it easy to rotate the entire rotating longitudinal frame 51 to open the rotating longitudinal frame 51;

[0052] When the inner slide 43 is controlled to slide out of the cabinet frame 1, the U-shaped bracket 81 and the ventilation inner filter frame 82 slide out, which facilitates the disassembly and replacement of the ventilation inner filter frame 82;

[0053] After the inspection is completed, the rotating mechanism 5 is rotated to reset, and the inner slide 43 is pushed in, the transmission gear 47 is meshed and connected with the transmission rack 471 again, and the transmission rack 471 can drive the transmission gear 47 to rotate in the opposite direction, thereby driving the driving worm 461 to drive the driven worm gear 46 and the rotating horizontal shaft 441 to rotate in the opposite direction, and then the roller frame 45 can be controlled to rotate, so that the auxiliary roller 451 rotates in the opposite direction, and the roller frame 45 and the auxiliary roller 451 can be stored on the side of the bottom guide rail 42 close to the rotating mechanism 5;

[0054] Subsequently, the cabinet door body 2 is rotated and closed, and one end of the bottom support frame 431 and the top support frame 434 close to the rotating mechanism 5 contacts the inner side of the cabinet door body 2, and the cabinet door body 2 limits the bottom support frame 431 and the top support frame 434 to prevent the bottom support frame 431 and the top support frame 434 from sliding by themselves, thereby improving the stability of the inner slide 43 and the electrical equipment 7.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
