[0002] A distribution cabinet is an important device in the power system for distributing and controlling electric energy. It not only converts high-voltage power into low-voltage power suitable for various electrical appliances but also provides functions such as overload protection and short-circuit protection to ensure electrical safety.
[0003] A distribution cabinet generally consists of a cabinet body and a cabinet door. Multiple brackets for installing electrical components are provided in the cabinet body, and equipment for heat dissipation is installed. The cabinet door serves a protective function and is in a closed state under normal conditions. The cabinet door is only opened during some maintenance and repair work.
[0004] Generally speaking, ventilation holes are provided on both the cabinet body and the cabinet door of the distribution cabinet, and in combination with the heat dissipation equipment, air circulation is achieved. Since it is necessary to protect the internal electrical components, the existing ventilation holes will not be enlarged or increased. To obtain a better heat dissipation effect, structural improvements are required. Therefore, a protective door mechanism for a high-voltage distribution cabinet is proposed to solve the above problems. Summary of the Invention

[0013] When the temperature outside the power distribution cabinet is lower than the inside and there is no rainfall in the environment, send a start command to the telescopic driving part through the power management system, so that the telescopic driving part drives the transparent plate structure to move horizontally to open the rectangular window.
[0014] Preferably, an image monitoring device is fixedly connected to the plate body and is arranged facing the outside of the power distribution cabinet. The step of analyzing the environment where the power distribution cabinet is located by combining the temperature, humidity and rainfall data in the meteorological data further includes:

[0016] Use computer vision technology to detect the features in the image to judge whether there is a raindrop trajectory in the image;
[0017] Construct a multi-modal model by combining the meteorological data and image detection. The multi-modal model is used to judge the rainfall situation at the location of the power distribution cabinet.
[0018] Preferably, the image monitoring device is also used to record maintenance personnel. The specific steps include:
[0019] When there is a person in the area of the power distribution cabinet, obtain the image of the person and record the entry time;
[0020] Perform face detection on the image of the person and extract facial features;
[0021] Compare the extracted features with the face database to identify the identity of the current person. The face database is established according to power maintenance personnel;
[0022] When it is recognized that the person is a certain maintenance personnel, record the departure time;
[0023] Generate a work record of power distribution cabinet maintenance according to the entry time, departure time and personnel identity.
[0024] Preferably, the transparent plate structure includes two glass plates arranged at intervals, and a flexible solar film interlayer is arranged between the glass plates. A plurality of battery panels electrically connected to the flexible solar film interlayer are fixedly connected to one side of the plate body far from the telescopic driving member.

It can not only facilitate personnel to observe the working conditions of the electrical components inside the power distribution cabinet, but also, when the heat dissipation pressure of the power distribution cabinet is relatively large, control the telescopic driving member to drive the transparent plate structure to move horizontally, so that the rectangular window is opened, thereby effectively increasing the air exchange efficiency inside and outside the power distribution cabinet. Combined with the original heat dissipation equipment, the heat dissipation effect is better. In summary, the present invention changes the original protective door structure of the power distribution cabinet, realizes the premise of protection by using a mobile transparent window, and can also play a role in promoting heat dissipation.

[0038] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0039] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.
[0040] As Figure 1 、 Figure 2 and Figure 3 shown, a protective door mechanism for a high-voltage power distribution cabinet provided by an embodiment of the present invention includes a plate body 2 rotatably hinged to the power distribution cabinet body 1, and further includes:
[0041] A window assembly, the window assembly is located on the plate body 2, the plate body 2 is of a hollow structure, a rectangular window 3 facing the inside of the power distribution cabinet body 1 is opened in the middle of the plate body 2, and horizontal slideway plates 4 are fixedly connected to both the bottom and the top of the rectangular window 3 in the plate body 2. The window assembly includes a transparent plate structure 5 located on the plate body 2 and corresponding to the position of the rectangular window 3. The top and the bottom of the transparent plate structure 5 are both slidably connected to the slideway plates 4, and the length and the width of the transparent plate structure 5 are both greater than the corresponding dimensions of the rectangular window 3;
[0042] A telescopic driving member 6 is arranged on one side of the transparent plate structure 5 in the plate body 2, and the telescopic driving member 6 is used to drive the transparent plate structure 5 to move horizontally in the plate body 2.
[0043] In an embodiment of the present invention, the present invention changes the cabinet door structure of the power distribution cabinet, adds a rectangular window 3 to the plate body 2, and sets a transparent plate structure 5 that can move horizontally in the rectangular window 3. This not only facilitates personnel to observe the working conditions of the electrical components inside the power distribution cabinet, but also when the heat dissipation pressure of the power distribution cabinet is relatively large, it can control the telescopic driving member 6 to drive the transparent plate structure 5 to move horizontally, so that the rectangular window 3 is opened, thereby effectively increasing the air exchange efficiency between the inside and outside of the power distribution cabinet. Combined with the original heat dissipation equipment, the heat dissipation effect is better. In summary, the present invention changes the original protective door structure of the power distribution cabinet, realizes the premise of protection by using a mobile transparent window, and can also play a role in promoting heat dissipation.
[0044] It should be noted that the movement of the transparent plate structure 5 is not unconditional. Because once the rectangular window 3 is opened, it means that the protection of the electrical components inside the power distribution cabinet is reduced. Therefore, it is necessary to explain the opening of the rectangular window 3. A temperature sensor is provided on the side of the plate body 2 facing the inside of the power distribution cabinet body 1, and the temperature sensor is used to control the operation of the telescopic driving member 6, as Figure 6 shown. The specific steps include:
[0045] S100, obtain the working temperature inside the power distribution cabinet through the temperature sensor, and obtain the meteorological data of the environment where the power distribution cabinet is located according to the position of the power distribution cabinet;
[0046] S200, extract the temperature data in the meteorological data and compare it with the working temperature to compare the temperature difference between the inside and outside of the power distribution cabinet;
[0047] S300, analyze the environment where the power distribution cabinet is located in combination with the temperature, humidity and rainfall data in the meteorological data;
[0048] S400, when the temperature outside the power distribution cabinet is lower than the inside and the environment is not raining, send a start command to the telescopic driving member 6 through the power management system, so that the telescopic driving member 6 drives the transparent plate structure 5 to move horizontally to open the rectangular window 3.
[0049] In this embodiment, because after the rectangular window 3 is opened, if the external environment is rainy, for an outdoor power distribution cabinet, it is impossible for rainwater to enter the power distribution cabinet. Therefore, the specific process of opening the rectangular window 3 described by the above method needs to be judged in combination with meteorological data. When it is learned that the location where the power distribution cabinet is located is not rainy, there is no impact when the rectangular window 3 is opened at this time. Of course, the opening of the rectangular window 3 is also time-limited, that is, when the heat dissipation pressure of the power distribution cabinet is relatively large, the transparent plate structure 5 can be controlled to move horizontally by the telescopic driving member 6. The telescopic driving member 6 can adopt a conventional electric telescopic or hydraulic telescopic form.
[0050] such asFigure 3 As shown in the figure, as a preferred embodiment of the present invention, an image monitoring device 7 facing the outside of the power distribution cabinet is fixedly connected to the plate body 2.
[0051] In one case of this embodiment, the image monitoring device 7 has multiple uses, such as Figure 7 As shown, the step of analyzing the environment where the power distribution cabinet is located by combining the temperature, humidity, and rainfall data in the meteorological data further includes:
[0052] S301, obtaining image data of the position of the power distribution cabinet through the image monitoring device 7;
[0053] S302, using computer vision technology to detect features in the image to determine whether there are raindrop trajectories in the image;
[0054] S303, combining the meteorological data and image detection to construct a multi-modal model, and the multi-modal model is used to judge the rainfall situation at the location of the power distribution cabinet.
[0055] Generally speaking, meteorological data will show the weather conditions in a region, but the power distribution cabinet is accurate to a specific location. It is obviously not accurate enough to judge whether the current environment where the power distribution cabinet is located is suitable for opening the rectangular window 3 only through meteorological data. At this time, the role of the image monitoring device 7 can be reflected. Image feature recognition can be used, the image and meteorological data can be combined, and a multi-modal model can be used to judge the weather at the location of the power distribution cabinet. This method is undoubtedly more accurate. Of course, the image data and meteorological data need to be unified in time.
[0056] Such as Figure 8 As shown, based on the above embodiment for supplementation, the image monitoring device 7 is also used to record maintenance personnel. The specific steps include:
[0057] S1, when a person appears in the area of the power distribution cabinet, obtaining the image of the person and recording the entry time;
[0058] S2, performing face detection on the image of the person and extracting facial features;
[0059] S3, comparing the extracted features with the face database for feature comparison to identify the identity of the current person, and the face database is established according to power maintenance personnel;
[0060] S4, when it is recognized that the person is a certain maintenance person, recording the departure time;
[0061] S5, generating a work record of power distribution cabinet maintenance according to the entry time, departure time, and personnel identity.
[0062] In a case of this embodiment, the imaging monitoring device 7 records the activities of power maintenance personnel in the distribution cabinet area, especially the time when they enter and leave, and confirms their identities through face recognition technology, and finally generates a work record. When someone appears around the distribution cabinet, the imaging monitoring device 7 installed here will automatically capture an image of this person. The system will record the specific time when this person enters the distribution cabinet area (i.e., the entry time). The image captured by the camera will be sent to a face recognition system, where face detection is first performed, that is, the position of the face is located in the image. Then, the system will extract unique facial features from the detected face. These features are key information for subsequent comparison. The extracted facial features will be compared with the data in a pre-established face database. This database contains the facial feature information of all known power maintenance personnel. Through this comparison, the system can identify whether the person currently appearing in the distribution cabinet area is one of the known maintenance personnel. When the system detects that the maintenance personnel has left the distribution cabinet area, it will record the specific time again (i.e., the departure time); finally, based on the entry time, departure time, and the identified personnel identity, the system automatically generates a work record for this distribution cabinet maintenance, including detailed information such as when a certain maintenance personnel carried out the maintenance work.
[0063] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, as a preferred embodiment of the present invention, the transparent plate structure 5 includes two glass plates 501 arranged at intervals, and a flexible solar film interlayer 502 is arranged between the glass plates 501. A plurality of battery plates 8 electrically connected to the flexible solar film interlayer 502 are fixedly connected to one side of the plate body 2 away from the telescopic driving member 6. A plurality of charging components 9 electrically connected to the battery plates 8 are arranged on one side of the plate body 2 facing the inside of the distribution cabinet body 1. Sealing gaskets 503 in contact with the inner wall of the plate body 2 are fixedly connected to the upper edges of both sides of the glass plates 501.
[0064] In one case of this embodiment, the charging assembly 9 includes a mounting frame 901 provided on the board body 2. A wireless charging module 902 and a plug-in charging module 903 are fixedly connected to the mounting frame 901. The mounting frame 901 is rotatably connected to the board body 2. Pull rods 10 are rotatably connected to both sides of the mounting frame 901. Vertical guide strips 11 are fixedly connected to both sides of the mounting frame 901 on the board body 2. The other end of the pull rod 10 is fixedly connected with a positioning pin that is slidably clamped with the guide strip 11. Since the power distribution cabinet is often set outdoors, maintenance personnel will carry various instruments and equipment. It is not uncommon to encounter the situation where the instruments and equipment cannot work properly due to insufficient power. The improvement of the transparent plate structure 5 can solve this problem. The flexible solar thin film between the glass plates 501 can convert solar energy into electric energy and transport it to the battery panel 8 for storage. When the maintenance personnel are working, the power distribution cabinet is in an open state. At this time, the instruments and equipment can be replenished with energy through the plug-in charging module 903 or the wireless charging module 902. Of course, the mounting frame 901 is also set to be foldable and can be maximally attached to the board body 2 when not in use. The maintenance personnel can use it according to their own needs. This power distribution cabinet can be used in the field of wind power generation, which can ensure that the maintenance personnel can inspect more equipment at one time and will not end the original inspection work in advance due to insufficient power of the instruments and equipment.
