DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0039] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0040] Relay protection devices play a vital role in power systems, monitoring the grid's operating status and promptly detecting and isolating faults to ensure system stability and safety. Relay protection cabinets, which house these critical devices, require strict procedures and safety regulations for maintenance, inspection, and testing.

[0041] In the prior art, identifying the status of equipment within cabinets primarily relies on traditional methods such as manually placed warning signs, padlocks, or electronic tags. While these methods can alert workers to the equipment's current operating mode to a certain extent, human factors such as negligence, misunderstanding, or incorrect placement of the label can lead to discrepancies between the actual equipment status and the indicated status. For example, workers might mistakenly mark a running device as "under maintenance" due to busyness or miscommunication, or forget to remove the "Do Not Operate" label from a device that has completed maintenance. Furthermore, traditional physical labels are susceptible to environmental factors such as falling off, being damaged, or being accidentally moved, further increasing the risk of confusion regarding equipment status. This not only poses a direct threat to the safety of on-site workers but can also lead to serious safety incidents. For example, workers might mistakenly enter a live cabinet to perform maintenance work, resulting in electric shock injuries; or they might unnecessarily deactivate the power supply to a device due to incorrectly assuming it is under maintenance, disrupting the normal operation of the power grid.

[0042] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0043] See also Figures 1 to 6 , an embodiment of the present application provides a double door, including a double door body 100, a mounting frame 200 and an identification member 300.

[0044] The double door body 100 includes a first door body 110 and a second door body 120 that are arranged opposite to each other.

[0045] A double door consists of two opposing doors, a first door 110 and a second door 120. These doors can be opened independently or simultaneously, facilitating access for maintenance personnel and equipment operation. The first and second doors 110, 120 are typically located on one side of the cabinet's opening and are hingedly connected to the cabinet for easy opening.

[0046] The mounting frame 200 includes a first frame body 210 and a second frame body 220. The first frame body 210 is arranged on the first door body 110, and the second frame body 220 is arranged on the second door body 120. The first frame body 210 is provided with a first mounting groove 211, and the second frame body 220 is provided with a second mounting groove 221. The mounting frame 200 is divided into two parts. The first frame body 210 is fixed to the first door body 110, and the second frame body 220 is correspondingly installed on the second door body 120. The first mounting groove 211 and the second mounting groove 221 can position and install the identification member 300, ensuring that the identification member 300 is installed firmly and is easy to observe. Optionally, the mounting frame 200 can be fixed to the double door by screwing or bonding.

[0047] The identification member 300 is disposed in the first installation groove 211 and the second installation groove 221 , and the identification member 300 is used to indicate status information of equipment in the double-door body 100 .

[0048] The identification member 300 displays the status of the equipment within the double-door housing. The identification member 300 can use an LED display, an electronic ink screen, colors, numbers, or Chinese characters to indicate the operating or maintenance status of the equipment. Clear indications, such as different colors or text, can be used to reduce the possibility of human error. For example, green indicates "operating" and red indicates "under maintenance." It is understood that the status information of the equipment within the double-door housing 100 includes the equipment's operating status, maintenance status, fault status, and other conditions.

[0049] When properly installed, the identification piece 300 acts as a barrier to prevent the double door from being opened at will. By physically locking the door with the identification piece 300, the double door cannot be opened unless the identification piece 300 is removed when the device is in a specific state (e.g., "Running"), thereby preventing accidental opening of the double door or misoperation.

[0050] As can be seen, the visual indication information and physical restriction of the door opening by the identification piece 300 provide a more intuitive prompt for the staff. Without having to judge other signals besides the identification piece 300, the staff only need to observe whether the identification piece 300 is installed and the information it displays to immediately know the status of the equipment in the double door and intuitively know whether the door is locked. This effectively simplifies the status confirmation process and reduces the risk of safety accidents caused by human error.

[0051] In addition, staff do not need to check the identification plate and door lock status separately. They only need to check the instruction information and installation status of the identification part 300 to confirm the equipment inside the double door and check the safety protection, which significantly improves the efficiency of on-site operations.

[0052] Therefore, in the embodiment of the present application, the identification member 300 is installed between the first door body 110 and the second door body 120 of the double door via the mounting frame 200. When the identification member 300 is on the mounting frame 200, it indicates that the equipment inside the double door is in the state indicated by the identification member 300. Furthermore, because the identification member 300 limits the position of the double door, the double door cannot be easily opened. In this way, the identification member 300 not only reminds the staff through the state it indicates, but also allows the staff to make a judgment based on whether the identification member 300 limits the position of the double door. This effectively simplifies the judgment process of the identification member 300 and reduces the difficulty for the staff to judge the status of the equipment inside the door.

[0053] In some optional embodiments, see Figure 2 The identification member 300 has a first side and a second side facing each other, the first side abuts against the groove body of the first installation groove 211, and the second side abuts against the groove body of the second installation groove 221, so that the identification member 300 is installed between the first frame 210 and the second frame 220.

[0054] During installation, the first side of the identification member 300 is closely attached to and fixed to the inner wall of the mounting slot of the first frame 210. Similarly, the second side of the identification member 300 is also closely connected to the inner wall of the mounting slot of the second frame 220. This connection ensures that the identification member 300 can be firmly embedded in the mounting frame 200 between the two doors, preventing it from falling off easily and maintaining good stability and durability.

[0055] Exemplarily, when the identification member 300 is installed in the installation frame 200 , the upper and lower sides of the identification member 300 abut against the two installation grooves, or the left and right sides of the identification member 300 abut against the two installation grooves.

[0056] In some optional embodiments, see Figure 2 The first mounting groove 211 is provided with a first abutting portion 215 and a first supporting portion 216 , and the identification member 300 is clamped between the first abutting portion 215 and the first supporting portion 216 .

[0057] The second mounting groove 221 defines a second abutting portion 225 and a second supporting portion 226 , and the identification member 300 is engaged between the second abutting portion 225 and the second supporting portion 226 .

[0058] The first abutment portion 215 in the first mounting groove 211 is located on one side of the groove, and is used to be in close contact with one side edge of the identification member 300, playing a role of preliminary positioning and support. The first support portion 216 is located on the other side of the groove, and is arranged opposite to the first abutment portion 215 or forms an angle area with the first abutment portion 215, forming a limited space that can just accommodate the other side edge of the identification member 300. When the identification member 300 is placed in, its two sides respectively abut against the first abutment portion 215 and the first support portion 216 to achieve a stable clamping fixation. Similarly, the second mounting groove 221 is also equipped with a second abutment portion 225 and a second support portion 226, and the design principle is the same as that of the first mounting groove 211.

[0059] Therefore, this embodiment enhances the installation stability and installation convenience of the identification member 300 through the abutment portion and the support portion.

[0060] Exemplarily, the first frame body 210 and the second frame body 220 are both L-shaped.

[0061] In some optional embodiments, the first frame 210 and the second frame 220 are symmetrically arranged on both sides of the door gap of the double-door body 100.

[0062] The door gap of the double door body 200 is the gap between the first door body 110 and the second door body 120. The mounting frame 200 is symmetrically provided with the identification member 300 located at the center between the two door bodies for easy observation.

[0063] In addition, the symmetrical arrangement of the installation frame 200 in the door gap also facilitates efficient and safe identification management, allowing staff to clearly identify the equipment status information conveyed by the identification piece 300, providing immediate and accurate guidance to operators, effectively avoiding operational errors caused by unclear identification or misunderstandings, and further improving the safety and efficiency of work in special environments such as relay protection rooms.

[0064] In some optional embodiments, the shape of the identification member 300 matches the shape of the installation frame 200 .

[0065] The matching shape of the identification member 300 and the mounting frame 200 reduces the need for adjustments during installation. Workers can quickly and accurately complete installation by simply aligning the identification member 300 with the mounting slot, improving work efficiency. Furthermore, the matching shape of the identification member 300 and the mounting frame 200 reduces gaps and the impact of environmental factors such as waterproofing and dustproofing, ensuring that the identification member 300 maintains good working condition in various working environments and extending its service life.

[0066] In some optional embodiments, the identification member 300 includes a first identification member 310 and a second identification member 320 , wherein the first identification member 310 indicates a first state of the device in the double-door body 100 , and the second identification member 320 indicates a second state of the device in the double-door body 100 .

[0067] The second identification member 320 includes a first identification plate 321 and a second identification plate 323 . One of the first identification plate 321 and the second identification plate 323 is disposed in the first installation slot 211 , and the other is disposed in the second installation slot 221 .

[0068] The second identification member 320 is located on a side of the first identification member 310 close to the double door body 100 .

[0069] The first identification part 310 is used to indicate a state of the equipment inside the double door, such as "in operation", while the second identification part 320 is used to indicate another different state, such as "under maintenance", making the state identification more diversified and able to adapt to more complex equipment management needs.

[0070] The first identification member 310 is positioned outside the second identification member 320. In addition to providing a status indicator, the first identification member 310 also serves as a physical barrier. When the first identification member 310 is removed from the first and second mounting slots 211, 221, the obscured second identification member 320 becomes visible, allowing the double door to open. The removal of the second identification member 320 directly correlates to the door's openability, providing an additional layer of safety during equipment maintenance or operation.

[0071] This structure also ensures that workers can only open the double doors and enter or operate the equipment when the equipment is in a suitable operating state, such as when it is waiting for maintenance, that is, when the first identification member 310 (representing a restricted state, such as "operating") is removed. Conversely, if the equipment is in operation, the presence of the first identification member 310 effectively prevents the door from being opened, avoiding potential safety risks.

[0072] Therefore, in the embodiment of the present application, the staff can determine the status of the equipment in the double door based on whether the first identification member 310 is located in the installation frame 200, which simplifies the operation process and improves work efficiency.

[0073] In some optional embodiments, see Figure 5 and Figure 6 The installation frame 200 further includes a first partition plate 212 and a second partition plate 222 .

[0074] The first partition plate 212 divides the first installation groove 211 into a first partition plate 213 and a second partition plate 214 . The first partition plate 213 is located on a side of the second partition plate 214 away from the first door body 110 .

[0075] The second partition plate 222 divides the second installation groove 221 into a third partition plate 223 and a fourth partition plate 224 . The third partition plate 223 is located on a side of the fourth partition plate 224 away from the second door body 120 .

[0076] The first identification member 310 is disposed in the first partition 213 and the third partition 223 , the first identification plate 321 of the second identification member 320 is disposed in the second partition 214 , and the second identification plate 322 is disposed in the fourth partition 224 .

[0077] The first partition 212 divides the first mounting slot 211 into two separate sections: the first partition 213 is located near the first door 110, while the second partition 214 is located away from the first door 110. This provides separate installation spaces for identification members 300 in different states, facilitating the installation and display of different identification members 300. Similarly, the second mounting slot 221 is divided into a third partition 223 and a fourth partition 224 by the addition of the second partition 222. The third partition 223 is located near the second door 120, while the fourth partition 224 is located away from the second door 120. This results in the first partition 213 corresponding to the third partition 22, and the second partition 214 corresponding to the fourth partition 224. The first identification member 310 is installed in the first compartment 213 and the corresponding third compartment 223 to indicate a specific state of the equipment in the double door. The second identification member 320 is divided into a first identification plate 321 and a second identification plate 322. The first identification plate is arranged in the second compartment 214, and the second identification plate is placed in the fourth compartment 224, together indicating another state or providing supplementary information.

[0078] In some optional embodiments, a first color layer is provided on the surface of the first identification member 310 , and a second color layer is provided on the surface of the second identification member 320 .

[0079] The first identification element 310 is covered with a first color layer, which is used to visually convey specific equipment status information. For example, green might represent "operating," while yellow might mean "standby" or "warning." The second identification element 320 is covered with a second color layer, which is designed to contrast sharply with the first color layer. For example, red is often used to indicate "under maintenance" or "stopped," allowing for quick visual distinction between different states.

[0080] In some optional embodiments, the mounting frame 200 is a transparent frame.

[0081] The mounting frame 200 is made of a transparent material, allowing the color layer of the sign 300 to fully display. This transparent frame ensures that the sign 300 is clearly visible even when the door is closed, allowing accurate reading of its status from either side of the door. The transparent material also facilitates inspection of the sign 300's integrity and vibrant color, facilitating routine maintenance and immediate status verification.

[0082] See also Figure 7 The present application also provides a cabinet comprising the double doors of any of the above embodiments. It is understood that the cabinet has the beneficial effects of the above double doors, which will not be described in detail here.
