A first positioning groove 4431 and a second positioning groove 4432 cooperating with the positioning rod 47 are provided on the upper side of the guide groove 443.

[0028] When it is necessary to move the lifting cabinet 3 up and down electrically, the driving shaft 44 is slid to make the positioning rod 47 cooperate with the first positioning slot 4431. At this time, the electric bevel gear 444 meshes with the transmission bevel gear 412, and the driving rod 441 is located in the driving slot 12. Starting the lifting motor 43 can drive the driving rod 441 to rotate through the auxiliary shaft 431, thereby driving the electric bevel gear to rotate through the driving shaft 44, and then driving the transmission bevel gear 412 to rotate the lifting screw 41, so as to realize the up and down sliding of the lifting cabinet 3; when it is necessary to manually lift the lifting cabinet 3, the driving shaft 44 can be pulled forward to make the positioning rod 47 cooperate with the second positioning slot 4432. At this time, the manual bevel gear 445 meshes with the transmission bevel gear 412 and the driving rod 441 is separated from the driving slot 12, so that the adjusting block 442 can be rotated by a wrench to rotate the driving shaft 44, and then the transmission bevel gear 412 is driven to rotate through the manual bevel gear 445, so as to realize manual lifting of the lifting cabinet 3.

[0029] Four supporting legs 13 are fixed to the lower side of the supporting cabinet 1, and two supporting holes of the same height are provided at the bottom of the lifting slot 11, and the supporting holes are located at the front and rear sides of the lifting screw 41 or the lifting shaft. The supporting mechanism 5 includes a supporting plate 51 slidably arranged in the lifting hole, and the supporting plate 51 is connected to the side of the lifting cabinet 3 away from the lifting cabinet 3 by a connecting plate 52, and a limiting plate 53 is fixed to the lower end of the connecting plate 52 near the supporting cabinet 1. A limiting hole 14 for the limiting plate 53 to be embedded is provided on the outer side of the supporting cabinet 1, a sliding hole is provided on the lower side of the limiting hole 14, and a limiting rod 54 is slidably arranged in the sliding hole, and a clamping hole 531 for the limiting rod 54 to be inserted is provided on the limiting plate 53, a baffle 55 is fixed to the lower end of the limiting rod 54, a limiting spring 56 is provided on the upper side of the baffle 55, and an adjusting rod 57 is fixed to the front side of the baffle 55, an adjusting slot 131 is provided on the supporting leg 13, and the adjusting rod 57 is slidably arranged in the adjusting slot 131, and the front ends of the two adjusting rods 57 are connected by an interlocking rod 571. A locking shaft 58 is provided in the middle of the limiting hole 14 and is rotatably connected to the supporting cabinet 1. The upper end of the locking shaft 58 penetrates into the lifting cabinet 3 and is fixed with a locking handwheel 581. The lower side of the lifting cabinet 3 is provided with a makeshift groove 312 for the locking handwheel 581 to be embedded in. A locking gear 59 is fixed on the locking shaft 58. Transmission racks 532 are meshed on the front and rear sides of the locking gear 59. The two transmission racks 532 are respectively connected to the two limiting rods 54. The locking gear 59 is driven to rotate by rotating the locking handwheel 581, thereby driving the limiting rod 54 to slide through the transmission rack 532, and then driving the connecting rod and the supporting plate 51 to slide.

[0030] When the moving block 311 abuts against the upper side wall of the lifting slot 11, the interlocking rod 571 is pressed down to make the limit rod 54 move down and staggered with the limit plate 53, and then the locking hand wheel 581 is turned to slide the connecting plate 52 until it abuts against the supporting cabinet 1, and then the interlocking rod 571 is loosened to make the limit rod 54 cooperate with the card hole 531. At this time, the support plate 51 moves to the lower side of the support rod to assist in supporting the moving block 311, reducing the force between the lifting screw 41 and the moving block 311, and improving the service life of the lifting screw 41; when it is necessary to move the lifting cabinet 3 downward, the interlocking rod 571 is pressed down to make the limit rod 54 move down and staggered with the limit plate 53, and then the locking hand wheel 581 is turned over to make the support plate 51 staggered with the moving block 311. At this time, the lifting cabinet 3 will not be restricted by the support plate 51 when moving up and down.

[0031] When people install or maintain the electrical components in the control cabinet, the mobile frame 31 can be lowered to the lowest position, which is convenient for people to install or maintain the electrical components on the mobile frame 31. After installing or maintaining the electrical components, the mobile frame 31 can be raised by the lifting motor 43 until the moving block 311 abuts against the upper side of the lifting slot 11, and then the locking hand wheel 581 is rotated so that the support plate 51 supports the mobile frame 31. At this time, the position of the electrical components is raised, so that when water accumulates at the control installation position, the accumulated water is not easy to contact the electrical components, making the electrical components not easy to be damaged. When water accumulates on the ground, in order to avoid installation hazards or other losses caused by power on, the components are usually inspected first. At this time, it is inconvenient to use the lifting motor 43 to move the mobile frame 31 downward. The driving shaft 44 can be manually rotated to lower the mobile frame 31, so that the inspection of the components is easier and more convenient.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
