Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to an instrument room and switch cabinet. Background Technology

[0002] In power systems, the instrument panel door of switchgear is a crucial interface for safe operation, functional integration, and status monitoring. It not only isolates personnel from high-voltage components but also facilitates human-machine interaction for operational commands, while simultaneously protecting the internal environment and providing intelligent monitoring of operational status. To meet these functional requirements, various secondary components are typically installed on the instrument panel door, such as different types of meters, indicator lights, selector switches, and buttons. These components are small in size but numerous, and their combined weight places the instrument panel door under significant load for extended periods.

[0003] During long-term operation of the switchgear, instrument doors are prone to sagging due to gravity and mechanical wear of the door hinges. This sagging not only leads to uneven gaps between the door and the cabinet and difficulty in opening and closing, affecting normal maintenance operations, but may also cause displacement or damage to secondary components, further threatening the overall stability and operational safety of the switchgear. Utility Model Content

[0004] The purpose of this application is to provide an instrument room and switch cabinet, which aims to solve the technical problem of how to prevent the instrument door of the switch cabinet from sagging in the prior art.

[0005] To achieve the above objectives, this application proposes an instrument room, the instrument room comprising:

[0006] The cabinet body and the cabinet door are rotatably connected to the cabinet body;

[0007] A limiting device includes a limiting member and a limiting hole. The limiting member is fixedly installed on the cabinet door, and the axis of the limiting member is perpendicular to the rotation axis of the cabinet door. The limiting hole is opened in the cabinet body and extends in a direction perpendicular to the rotation axis of the cabinet door. The limiting member can be inserted into the limiting hole. When the limiting member is inserted into the limiting hole, it can provide a vertically upward supporting force for the cabinet door. When the limiting member is removed from the limiting hole, the cabinet door can rotate.

[0008] In one embodiment, the limiting member is fixedly disposed at the end of the cabinet door away from the rotation axis, and the limiting hole is correspondingly opened at the end of the cabinet body away from the rotation axis of the cabinet door, and the limiting member can be inserted into or removed from the limiting hole.

[0009] In one embodiment, the cabinet includes a cabinet body, a base plate, and an extension plate fixedly disposed on the base plate. The extension plate is located on the side of the base plate near the cabinet door. The limiting hole is formed in the extension plate and is used to insert and cooperate with the limiting member.

[0010] In one embodiment, the diameter of the limiting hole is larger than the outer diameter of the limiting member, so that the limiting member can be inserted into or removed from the limiting hole.

[0011] In one embodiment, the limiting hole is oblong in shape, and the long axis of the oblong extends in a direction perpendicular to the rotation axis of the cabinet door.

[0012] In one embodiment, the limiting hole is elliptical in shape, and the minor axis of the ellipse extends in a direction parallel to the rotation axis of the cabinet door.

[0013] In one embodiment, the limiting member includes a support base and a limiting post fixed to the support base. The support base is fixedly disposed on the inner side wall of the cabinet door, and the limiting post can be inserted into or removed from the limiting hole.

[0014] In one embodiment, the limiting post includes a post body and a connecting portion and a limiting portion located at both ends of the post body. The connecting portion is fixedly connected to the support base, and the limiting portion can drive the post body to insert into or move out of the limiting hole.

[0015] In one embodiment, the limiting part is a hemispherical structure, and the convex surface of the hemispherical structure faces the limiting hole.

[0016] In addition, to achieve the above objectives, this application also proposes a switch cabinet, which includes an instrument compartment as described above.

[0017] The above-mentioned technical solution of this application has at least the following beneficial technical effects:

[0018] The technical solution of this application adopts a limiting component and a limiting hole for plug-in cooperation. When the limiting component is inserted into the limiting hole, it can provide vertical upward support for the cabinet door. When the limiting component is removed from the limiting hole, the cabinet door can rotate, thereby effectively preventing the instrument door from sagging, ensuring the normal use of the switchgear and the safety of the internal components, thereby improving the operational reliability and safety of the switchgear, extending the service life of the equipment, and reducing maintenance costs.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0025] The embodiments described in this application are only some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application.

[0026] In power systems, the instrument panel door of switchgear is a crucial interface for safe operation, functional integration, and status monitoring. It not only isolates personnel from high-voltage components but also facilitates human-machine interaction for operational commands, while simultaneously protecting the internal environment and providing intelligent monitoring of operational status. To meet these functional requirements, various secondary components are typically installed on the instrument panel door, such as different types of meters, indicator lights, selector switches, and buttons. These components are small in size but numerous, and their combined weight places the instrument panel door under significant load for extended periods.

[0027] During long-term operation of the switchgear, instrument doors are prone to sagging due to gravity and mechanical wear of the door hinges. This sagging not only leads to uneven gaps between the door and the cabinet and difficulty in opening and closing, affecting normal maintenance operations, but may also cause displacement or damage to secondary components, further threatening the overall stability and operational safety of the switchgear.

[0028] To address the aforementioned technical problems, this application proposes an instrument compartment. Please refer to [link / reference needed]. Figure 1 and Figure 2In one embodiment of this application, the instrument compartment includes a cabinet 100, a cabinet door 200, and a limiting device 300. The cabinet door 200 is rotatably connected to the cabinet 100. Specifically, the rotatable connection between the cabinet door 200 and the cabinet 100 can be a hinge connection or a pin-type pivot connection, which is not limited here. The limiting device 300 includes a limiting member 310 and a limiting hole 320. The limiting member 310 is fixedly disposed on the cabinet door 200, and the axis of the limiting member 310 is perpendicular to the rotation axis of the cabinet door 200. The limiting hole 320 is opened in the cabinet 100 and extends in a direction perpendicular to the rotation axis of the cabinet door 200. The limiting member 310 can be inserted into the limiting hole 320. When the limiting member 310 is inserted into the limiting hole 320, it can provide a vertically upward support force for the cabinet door 200. When the limiting member 310 is removed from the limiting hole 320, the cabinet door 200 can rotate.

[0029] The technical solution of this application adopts a limiting member 310 and a limiting hole 320 for plug-in cooperation. When the limiting member 310 is inserted into the limiting hole 320, it can provide vertical upward support for the cabinet door 200. When the limiting member 310 is removed from the limiting hole 320, the cabinet door 200 can rotate, thereby effectively preventing the instrument door from sagging, ensuring the normal use of the switchgear and the safety of internal components, thereby improving the operational reliability and safety of the switchgear, extending the service life of the equipment, and reducing maintenance costs.

[0030] Please see Figure 1 and Figure 2 In one embodiment, a limiting member 310 is fixedly disposed at the end of the cabinet door 200 away from the rotation axis, and a corresponding limiting hole 320 is opened at the end of the cabinet body 100 away from the rotation axis of the cabinet door 200. The limiting member 310 can be inserted into or removed from the limiting hole 320. This embodiment, through the cooperation of the limiting member 310 and the limiting hole 320, ensures that the cabinet door 200 can be accurately positioned during opening and closing, avoiding damage or affecting the use of the cabinet door 200 due to excessive swinging, and improving the stability and safety of the cabinet door 200.

[0031] Please see Figure 1 and Figure 2 In one embodiment, the cabinet 100 includes a cabinet body 110, a base plate 120, and an extension plate 130 fixedly disposed on the base plate 120. The extension plate 130 is located on the side of the base plate 120 near the cabinet door 200. A limiting hole 320 is formed in the extension plate 130 for insertion and engagement with a limiting member 310. This embodiment, by providing a limiting hole 320 on the extension plate 130, enables the limiting member 310 to be stably inserted, enhancing the fit between the cabinet door 200 and the cabinet body 100, preventing the cabinet door 200 from shaking during opening and closing, and improving the overall structural stability and durability.

[0032] Please see Figure 1 and Figure 2 In one embodiment, the diameter of the limiting hole 320 is larger than the outer diameter of the limiting member 310, so that the limiting member 310 can be inserted into or removed from the limiting hole 320. In this embodiment, the diameter of the limiting hole 320 is designed to be larger than the outer diameter of the limiting member 310, thereby allowing the limiting member 310 to be smoothly inserted into or removed from the limiting hole 320, providing a clearance for the limiting member 310 to move, and avoiding difficulty in insertion or jamming due to excessively small size. At the same time, this design also allows the limiting member 310 to move freely within a certain range, thereby facilitating the adjustment and operation of the cabinet door 200, and ensuring the smoothness and stability of the opening and closing of the cabinet door 200.

[0033] Please see Figure 2 and Figure 3 In one embodiment, the limiting hole 320 is oblong in shape, with its long axis extending perpendicular to the rotation axis of the cabinet door 200. In this embodiment, the oblong shape of the limiting hole 320, with its long axis extending perpendicular to the rotation axis of the cabinet door 200, helps adjust the position and angle of the cabinet door 200 during opening and closing, allowing the cabinet door 200 to move freely within a wider range. The long axis allows the limiting hole 320 to accommodate a certain degree of vertical displacement of the limiting member 310, thereby providing flexible limiting control when the cabinet door 200 rotates, preventing excessive opening and closing or jamming of the cabinet door 200, and improving the stability and comfort of use.

[0034] Please see Figure 2 and Figure 3 In one embodiment, the limiting hole 320 is elliptical in shape, with the minor axis of the ellipse extending in a direction parallel to the rotation axis of the cabinet door 200. In this embodiment, the limiting hole 320 is designed to be elliptical, and the minor axis of the ellipse extends in a direction parallel to the rotation axis of the cabinet door 200. This design creates a certain constraint in the direction parallel to the rotation axis of the cabinet door 200, effectively controlling the range of motion of the limiting member 310 in this direction. Simultaneously, the major axis of the ellipse provides the necessary insertion and removal allowance for the limiting member 310, allowing it to smoothly insert into or remove from the limiting hole 320. This structure not only improves the fitting accuracy between the limiting member 310 and the limiting hole 320 but also enhances stability and smoothness during the opening and closing of the cabinet door 200, avoiding jamming problems caused by excessive interference or friction.

[0035] Please see Figure 2 and Figure 3In one embodiment, the limiting member 310 includes a support base 311 and a limiting post 312 fixed to the support base 311. The support base 311 is fixedly disposed on the inner side wall of the cabinet door 200, and the limiting post 312 can be inserted into or removed from the limiting hole 320. In this embodiment, the limiting member 310 consists of a support base 311 and a limiting post 312 fixed to the support base 311. The support base 311 is fixedly disposed on the inner side wall of the cabinet door 200 to ensure that the limiting member 310 can be stably fixed on the cabinet door 200. The limiting post 312 can be inserted into or removed from the limiting hole 320 to control the opening and closing range of the cabinet door 200.

[0036] Please see Figure 2 and Figure 3 In one embodiment, the limiting post 312 includes a post body 3121 and connecting portions 3122 and limiting portions 3123 located at both ends of the post body 3121. The connecting portions 3122 are fixedly connected to the support base 311, and the limiting portions 3123 can drive the post body 3121 to insert into or move out of the limiting hole 320. This embodiment, through the design of the limiting post 312, allows the limiting portions 3123 to drive the post body 3121 to insert into or move out of the limiting hole 320, providing flexible limiting control and ensuring that the opening and closing angle of the cabinet door 200 is effectively limited, avoiding damage or jamming caused by excessive opening and closing. The limiting post 312 is fixedly connected to the support base 311 through the connecting portions 3122, enhancing the stability and durability of the limiting component 310 and preventing loosening that may occur during use. This structure simplifies the adjustment process, making the opening and closing operation of the cabinet door 200 smoother, improving the user experience, and also reducing the difficulty of maintenance and adjustment.

[0037] Please see Figure 2 and Figure 3 In one embodiment, the limiting part 3123 has a hemispherical structure, with the convex surface of the hemispherical structure facing the limiting hole 320. This embodiment, by using a hemispherical structure with the convex surface of the limiting part 3123 facing the limiting hole 320, can guide and reduce resistance when inserting or removing it from the limiting hole 320, making the movement of the column body 3121 smoother, reducing wear caused by friction, extending its service life, and improving the stability and convenience of opening and closing the cabinet door 200.

[0038] In addition, to achieve the above objectives, this application also proposes a switch cabinet, which includes an instrument room. The specific structure of the instrument room is as described in the above embodiments. Since this switch cabinet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
