Description

TECHNICAL FIELD

[0001] The utility model relates to a switch cabinet technical field, concretely relates to a switch cabinet. BACKGROUND

[0002] In the traditional switch cabinet design, the sealing between the cabinet and the door is often a key problem. Since the switch cabinet integrates multiple circuit breakers and power components inside, these components have high requirements for the environment, especially the prevention of the infiltration of foreign matter or liquid to avoid short circuit, failure or even safety accidents. The traditional switch cabinet usually only sets a simple sealing strip at the edge of the door, but such design often has poor sealing effect, especially at the interface between the door and the cabinet, which is easy to have gaps due to poor sealing, allowing foreign matter or liquid to seep into the cabinet.

[0003] In addition, even if a more complex sealing structure is used, there are often problems such as inconvenient installation and difficult maintenance. For example, some sealing elements are prone to aging and deformation after long-term use, resulting in a decline in sealing performance, and replacing these sealing elements may require disassembling the entire door, which is cumbersome and affects the normal use of the switch cabinet.

[0029] Example 1

[0030] like Figures 1-4 A switch cabinet is shown, the switch cabinet comprising:

[0031] A cabinet 10 having an opening 11, wherein a plurality of circuit breakers and power supply components are disposed in the cabinet 10, wherein an outwardly extending convex wall 12 is disposed at the opening 11 of the cabinet 10, and an outwardly opening retaining wall 13 is disposed at the distal end of the convex wall 12;

[0032] The cabinet door 14 is rotatably mounted on the cabinet body 10. The edge of the cabinet door 14 is provided with a side facing the cabinet body 10. A sealing block 15 cooperating with the retaining wall 13 is provided on the side at the top, and a flexible sealing member 16 is clamped on the sealing block 15; the convex wall 12, the retaining wall 13 and the sealing block 15 form a cavity 17 for accommodating foreign matter or liquid. The sealing member 16 is used to isolate the gap at the top of the cavity 17 to prevent foreign matter or liquid from penetrating into the cabinet body 10. The bottom of the cavity 17 is provided with a guide groove 18 extending obliquely to both sides.

[0033] Specifically, both ends of the seal 16 are provided with plug-in ends 22, and the sealing block 15 is provided with a slot 21 for the plug-in end 22 to be fitted, wherein the sealing block 15 is also provided with a groove 25 for clamping the retaining wall 13, and the seal 16 is provided with a recessed portion 20 that is clamped into the groove 25 to fill the gap between the retaining wall 13 and the groove 25; the front end of the seal 16 is provided with an inclined surface 24, and the seal 16 is provided with a thickening layer 23 on one side of the bottom of the inclined surface 24, and when the cabinet door 14 is closed, the thickening layer 23 abuts against the top surface of the convex wall 12 to prevent foreign matter or liquid from entering the cabinet body 10.

[0034] The top of the recessed portion 20 is further provided with a plurality of protrusions 26 for cooperating with the end of the retaining wall 13 to form a shielding structure. The shape of the recessed portion 20 is the same as that of the retaining wall 13. In particular, in this embodiment, the sealing member 16 is made of polyurethane, and the sealing block 15 is welded to the cabinet door 14, that is, the sealing block 15 is welded to the inner side of the top of the bent portion of the cabinet door 14.

[0035] The embodiment also provides a manufacturing step of the switch cabinet, and the specific implementation steps are as follows: step one: selecting a suitable polyurethane material as the material of the sealing element 16. The polyurethane material has good high-temperature resistance and low-temperature resistance, can maintain good sealing performance for a long time, and reduces the risk of foreign matter and liquid seeping into the cabinet body 10. Step two: designing the shape and size of the sealing element 16 according to different models and specifications. The shape and size of the sealing element 16 can be adjusted according to different models and specifications, thereby enhancing the application range. Step three: installing the self-sealing structure. The self-sealing structure is designed simply, so that installation and maintenance are more convenient, and maintenance cost and time are reduced. Specifically, the sealing block 15 is welded to the cabinet door 14, that is, the sealing block 15 is welded to the inner side of the top of the bent part of the cabinet door 14, thereby enhancing the fixity and stability of the sealing block 15. Step four: further enhancing the sealing effect of the self-sealing structure. The sealing effect is further enhanced by cooperation of the convex wall 12, the blocking wall 13 and the sealing block 15, and design of the thickened layer 23 and the inclined surface 24 of the sealing element 16, thereby preventing foreign matter and liquid from seeping into the cabinet body 10. Step five: setting the flow guide groove 18 to prevent foreign matter and liquid from accumulating at the bottom of the cavity 17. The bottom of the cavity 17 of the self-sealing structure is provided with the flow guide groove 18 extending to the two sides, which can effectively guide foreign matter and liquid to be discharged, thereby further improving the sealing effect. Step six: checking and testing the performance of the self-sealing structure. Through testing, it is ensured that the self-sealing structure can effectively prevent foreign matter and liquid from seeping into the cabinet body 10 and has good high-temperature resistance and low-temperature resistance. The above is the specific implementation step of the embodiment. Through the steps, the switch cabinet with the self-sealing structure can be realized, the problems in the prior art are solved, and the sealing performance and safety of the switch cabinet are improved.

[0036] The above-described embodiments merely describe the preferred implementation of the present application, and do not limit the design concept and scope of the present application. Without departing from the design concept of the present application, various modifications and improvements of the technical solution of the present application made by those skilled in the art shall fall within the protection scope of the present application, and the technical content of the present application claimed for protection has been entirely recorded in the claims.
