Description

Technical Field

[0001] This utility model relates to the field of switch cabinets, and in particular to a high-precision environmental protection cabinet welding device. Background Technology

[0002] Switchgear is an electrical device primarily used in power systems for opening, closing, controlling, and protecting electrical equipment during power generation, transmission, distribution, and energy conversion. Environmental protection cabinets are a type of switchgear. To ensure the performance of environmentally friendly gases or solid insulating materials, their structural design is more compact, with higher sealing requirements. They typically employ a fully insulated and fully enclosed structure to minimize the impact of the external environment on insulation performance. Therefore, environmental protection cabinets have higher requirements for the welding of the cabinet body. Currently, some problems exist in the welding process of environmental protection cabinets; the cabinet body is prone to deformation under high-temperature welding conditions, thus affecting the cabinet's sealing and other characteristics.

The rear abutment mechanism includes a slider, and the slider includes a slide groove adapted to the shape of the slide rail. The slider can slide on the slide rail so that the rear abutment mechanism can slide relative to the base along the extension direction of the slide rail.

[0005] The rear support mechanism includes a base, and the slider is located below the base; the base is provided with a limiting block, and the base is provided with a limiting pin that can prevent the limiting block from moving forward.

[0016] This utility model discloses a pre-welded device structure for an environmental protection cabinet that is convenient to use and highly accurate. It includes a base, a front support mechanism, and a rear support mechanism. The front support mechanism and the rear support mechanism are arranged opposite each other and abut against two opposite side plates of the environmental protection cabinet. The base is provided with a slide rail, and the rear support mechanism includes a slider. The slider includes a groove that adapts to the shape of the slide rail. The slider can slide on the slide rail so that the rear support mechanism can slide relative to the base along the extension direction of the slide rail. The rear support mechanism has a gap between its first auxiliary bracket and the first top plate, sufficient to accommodate one side panel of the environmental protection cabinet; the front support mechanism has a gap between its second auxiliary bracket and the second top plate, sufficient to accommodate the other side panel of the environmental protection cabinet. In use, one side panel of the environmental protection cabinet is placed into the gap between the first auxiliary bracket and the first top plate, and the other side panel is placed into the gap between the second auxiliary bracket and the second top plate.

The base 32 is provided with a limiting block 33, and the base 1 is provided with a limiting pin 34 that can prevent the limiting block 33 from moving forward. In this embodiment, the base 1 is provided with a plurality of pin holes 12 along the extension direction of the slide rail 11, and the limiting pin 34 is detachably connected to at least one of the pin holes 12, thereby making the position of the limiting pin 34 adjustable. In this embodiment, the plurality of pin holes 12 are sequentially arranged on one side of the slide rail 11, and there are two limiting pins 34, which define the movable stroke of the base.

[0023] In this embodiment, the base 1 includes a base plate 13, and the front support mechanism 2 is located at one end of the base plate 13. The base plate 13 is provided with two slide rails 11, and the base 32 is provided with two sliders 31 corresponding to the two slide rails 11 below it. In this embodiment, the base 1 includes two spaced-apart base plates 13, and the rear support mechanism 3 includes two bases 32, which are slidably connected to the slide rails 11 on the two base plates 13.

[0026] In this embodiment, the rear support mechanism 3 includes a first auxiliary support 38, and there is a gap between the first auxiliary support 38 and the first top support plate 35 that can accommodate one side panel 10 of the environmental protection cabinet; the front support mechanism 2 includes a second auxiliary support 23, and there is a gap between the second auxiliary support 23 and the second top support plate 21 that can accommodate the other side panel of the environmental protection cabinet.

[0027] In actual operation, one side panel 10 of the environmental protection cabinet is placed into the gap between the first auxiliary support 38 and the first top plate 35, and the other side panel 20 is placed into the gap between the second auxiliary support 23 and the second top plate 21. The rear top-supporting mechanism 3 is pushed to slide along the extension direction of the slide rail 11 until it reaches the welding position. The welding position is determined by the environmental protection cabinet to be welded. The limiting pin 34 is placed in the pin hole 12 corresponding to the width of the environmental protection cabinet body, and the rear top-supporting mechanism 3 slides until the slider 31 abuts against the limiting pin 34. The top cover plate 30 of the environmental protection cabinet is placed on top of the two side panels 10 and 20, and welding can begin. The structure of this utility model can adapt to environmental protection cabinets of different sizes, and cabinets of different widths can be firmly clamped, ensuring the versatility of the device and the precision of processing, and avoiding deformation problems caused by excessively high temperatures during welding.
