Abstract
Description
Technical Field
[0001] The utility model relates to a high-voltage switch cabinet, in particular to a door plate of a high-voltage switch cabinet which is anti-electricity-theft. Background Art
[0002] High-voltage switchgear is used for switching, controlling, or protecting power generation, transmission, distribution, conversion, and consumption in power systems. It is primarily used in a variety of locations, including power plants, substations, petrochemicals, metallurgy, steel rolling, light industry, textiles, factories, mining enterprises, residential communities, and high-rise buildings. Existing high-voltage switchgear doors have exposed hinges, which lack anti-theft protection. Furthermore, these doors lack strength, are prone to deformation, and do not close smoothly with the cabinet body, resulting in poor sealing. Summary of the Invention
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a high-voltage switch cabinet middle door plate with simple structure, stable and reliable performance, good sealing performance and high strength to prevent electricity theft.
[0004] To achieve the above-mentioned purpose, the present invention adopts a door panel of a high-voltage switch cabinet for preventing electricity theft, including a door panel body and multiple hinges. One side of the door panel body has a supporting folded edge bent into an integrated structure, and the tail of the supporting folded edge is bent inward to form a folded edge for pressing the sealing strip. A fixing groove is formed between the supporting folded edge and the folded edge. The multiple hinges are respectively arranged in the fixing grooves at intervals. The door panel body has three reinforcing folded edges bent into an integrated structure. The three reinforcing folded edges are surrounded by the supporting folded edge to form a reinforcing frame. The three reinforcing folded edges are respectively bent inward to form sealing folded edges for pressing the sealing strip.
[0005] The beneficial effects of the above structure are: multiple hinges are set in the fixing grooves of the door panel body, and the hinges adopt a concealed structure design to prevent the hinges from being exposed outside the door panel body, thereby improving the anti-theft performance. The supporting fold and three reinforcing folds form a reinforced frame, which is beneficial to improving the overall strength of the middle door panel. The fold and sealing bend can be pressed tightly against the sealing strip of the cabinet body, thereby improving the sealing performance of the middle door panel and ensuring a smooth closing of the middle door panel and the cabinet body. As a result, the middle door panel of the high-voltage switchgear has the advantages of simple structure, stable and reliable performance, good sealing performance, high strength, and anti-theft performance.
[0006] In particular, the outer side of the support fold is provided with a slanted surface that matches the cabinet body. The slanted surface can play a slanting role, thereby avoiding interference between the support fold and the cabinet body, so that the door panel body can open at a larger angle.
[0007] Specifically, the hinge is provided with an arc-shaped positioning groove that cooperates with the supporting hem, and the supporting hem has an arc-shaped raised portion that cooperates with the arc-shaped positioning groove, and the arc-shaped raised portion abuts against the arc-shaped positioning groove. The arc-shaped raised portion of the supporting hem abuts against the hinge, and the supporting hem supports the hinge, thereby ensuring a more compact connection between the hinge and the door panel body.
[0008] In particular, the supporting hem has abutment portions at both ends that cooperate with the two reinforcing hems, and the reinforcing hem has snap-fitting grooves that cooperate with the abutment portions. The abutment portions snap into the snap-fitting grooves, forming a snap-fitting engagement between the abutment portions and the reinforcing hem. The support hem and the reinforcing hem are assembled using a snap-fitting engagement, thereby ensuring the overall strength of the reinforced frame.
[0009] In particular, a fixing block is welded in the fixing groove corresponding to each hinge, and the hinge is fixed to the fixing block by screws. The hinge is connected to the door panel body through the fixing block, thereby ensuring a stronger connection between the hinge and the door panel body.
[0010] In particular, a limiting groove is provided in the fixing groove corresponding to the fixing block, and the fixing block is engaged in the limiting groove. The fixing block is engaged in the limiting groove, which facilitates welding of the fixing block and the fixing groove and ensures that the welding of the fixing block and the fixing groove is more firm.

[0014] like Figures 1 to 3As shown, an embodiment of the present invention is a door panel for a high-voltage switchgear cabinet that prevents electricity theft. The door panel comprises a main body 10 and multiple hinges 11. One side of the main body 10 has a support flange 12 bent into an integral structure. The tail of the support flange 12 is bent inwardly to form a flange 13 for compressing a sealing strip. A fixing groove 14 is formed between the support flange 12 and the flange 12. The multiple hinges 11 are spaced apart and disposed within the fixing grooves 14. The main body 10 has three reinforcing flanges 15 bent into an integral structure. The three reinforcing flanges 15 and the support flange 12 enclose a reinforcing frame 100. Each of the three reinforcing flanges 15 is bent inwardly to form a sealing flange 16 for compressing the sealing strip. The outer side of the support flange 12 is provided with a relief bevel 121 that mates with the cabinet body. The relief bevel serves to provide clearance, thereby preventing interference between the support flange and the cabinet body, thereby allowing the door panel to open at a wider angle. The hinge 11 is provided with an arc-shaped positioning groove 111 that cooperates with the supporting flange 12. The supporting flange 12 has an arc-shaped raised portion 122 that cooperates with the arc-shaped positioning groove 111. The arc-shaped raised portion 122 abuts against the arc-shaped positioning groove 111. The arc-shaped raised portion of the supporting flange abuts against the hinge, supporting the hinge and thus ensuring a more compact connection between the hinge and the door panel body.
[0015] like Figure 1 and 2 As shown, the two ends of the supporting fold 12 have a contact portion 123 that cooperates with two of the reinforcing folds 12, and the reinforcing fold 15 has a snap-fit groove 151 that cooperates with the contact portion 123. The contact portion 123 is snap-fitted into the snap-fit groove 151, and forms a snap-fit between the contact portion 123 and the reinforcing fold 15. The supporting fold and the reinforcing fold are assembled using a snap-fit method, thereby ensuring the overall strength of the reinforced frame. A fixing block 17 is welded to each hinge 11 in the fixing groove 14, and the hinge 11 is fixed to the fixing block 17 by screws. The hinge is connected to the door panel body through the fixing block, thereby ensuring a more secure connection between the hinge and the door panel body. A limiting groove 141 is provided in the fixing groove 14 corresponding to the fixing block 17, and the fixing block 17 is snap-fitted into the limiting groove 141. The fixing block is engaged in the limiting groove, which facilitates the welding of the fixing block and the fixing groove and ensures that the welding of the fixing block and the fixing groove is more firm.
[0016] Multiple hinges are installed in the fixing grooves of the door panel body. The concealed hinge design prevents the hinges from being exposed outside the door panel body, improving the anti-theft performance. The supporting fold and three reinforcing folds form a reinforced frame, which helps to improve the overall strength of the middle door panel. The fold and sealing bend can be pressed against the sealing strip of the cabinet body, which helps to improve the sealing performance of the middle door panel and ensure a smooth closing between the middle door panel and the cabinet body. As a result, the high-voltage switchgear middle door panel has the advantages of simple structure, stable and reliable performance, good sealing performance, high strength, and anti-theft performance.
