At present, outdoor cabinets are usually dustproof and splashproof, with a protection level of only IP4X, and a small number of IP54. As a result, many outdoor cabinets are installed in inappropriate locations, occupy a large amount on the road, and are scattered and numerous, which has a certain impact on the road environment. Therefore, it is necessary to develop a sealing protection structure for underground power equipment with high waterproof grade, hard strength, and strong structural sealing. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problems and to provide a cover structure for underground equipment, which can effectively solve the problem that outdoor cabinets are usually dustproof and splashproof, and the protection level only reaches IP4X, and a small number is IP54. As a result, many outdoor cabinets are installed in inappropriate locations, occupy a large amount on the road, are scattered and numerous, and have a certain impact on the road environment.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof welding cabinet, a cover plate, an emergency handle, a limit device, an adjustable hinge, a waterproof sealing strip, a hinge shaft pin, a hinge fixing seat, an emergency handle fixing seat, a handle base trapezoidal block, a hinge fixing seat pin hole, and the cover plate of the waterproof welding cabinet is formed with a waterproof sealing structure by the emergency handle, the waterproof sealing strip, and the adjustable hinge.

[0005] As a preferred embodiment, the waterproof welded cabinet has a certain amount of flexible deformation after the box body and cover are installed. A circle of evenly distributed emergency handles are welded on the cover of the welded cabinet. The sealing strip in the cover is pressed from loose to tight through the trapezoidal block at the handle base to meet the compression amount of the sealing strip.

[0006] Preferably, an adjustable hinge is welded on the sealed box body of the waterproof welded cabinet, and the hinge fixing seat pin holes of the adjustable hinge adopt upper and lower waist-shaped holes, which are used as cover plate guides and lateral positioning, and can be loosened and moved freely in the longitudinal direction.

[0007] As a preferred embodiment, the sealed box body of the waterproof welded cabinet is welded with an adjustable hinge. When the cover is closed, the adjustable hinge is only positioned left and right, loose up and down, and does not participate in the sealing compression effect. The compression of the cover is completed by a circle of tight handles on the cover.

[0008] Preferably, the cover plate adopts a foamed silicone sealing strip. To ensure the compression balance of the four sides of the cover plate, a limit device is used to fix the upper and lower distances of the cover plate, and then the emergency handle fixing seat is welded and positioned. After welding, the limit device is removed.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The waterproof welded cabinet is made of fully sealed welded steel plates. The cabinet and cover have a certain amount of flexible deformation after installation. Adjustable hinges are installed around the sealing surface of the cabinet and cover. Evenly arranged emergency handles are used in conjunction with waterproof sealing strips. A limit device is used to adjust the sealing gap, which can overcome the flexible deformation of the sealed cabinet and cover, so that the protection level and cabinet strength of the waterproof cabinet reach IP level waterproof effect, which can effectively meet the anti-immersion requirements of thin-plate metal sealed cabinets installed underground, and realize the anti-immersion use requirements of outdoor buried installations such as power cabinets and telecommunication cabinets. It is suitable for the design and application of underground cabinet equipment installed and used in pipe corridors, cable trenches, and underground foundation pits.
