Furthermore, this utility model also relates to a high-voltage switchgear including the aforementioned observation window. Background Technology
[0002] In industrial environments such as chemical production, high-voltage switchgear is an important electrical equipment; in order to ensure the safe operation of the equipment, it is necessary to regularly inspect the internal condition of the high-voltage switchgear.
[0003] However, due to the long-term chemical production environment, the transparent plate inside the observation window of the high-voltage cabinet may become blurred due to aging or impurities adhering to its surface, resulting in a decrease in light transmittance and making it impossible to clearly observe the internal situation.
[0004] In addition, traditional observation windows are usually isolated by glass, making it difficult for handheld thermometers to accurately measure the temperature inside the high-voltage cabinet.
[0005] In summary, how to solve the problems of not being able to clearly observe the internal situation of the high-voltage cabinet after the light transmittance of the transparent plate decreases and the inaccurate internal temperature measurement caused by the transparent plate obstruction are problems that urgently need to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide a high-voltage cabinet observation window. The window assembly is driven by an electric push rod, so that the observation window is in an unobstructed state, which effectively solves the problems of unclear observation caused by the decrease in the light transmittance of the window assembly and inaccurate temperature measurement caused by the obstruction of the window assembly. At the same time, a face recognition module is added to control whether the observation window is opened by verifying user permissions, so as to avoid safety accidents caused by the opening of the observation window.
[0007] Another objective of this utility model is to provide a high-voltage switchgear that includes the observation window of the high-voltage switchgear described above, which has the same technical solution and can solve the same technical problem.

[0021] Preferably, the window assembly includes a transparent panel, a frame surrounding the transparent panel, and a sealing ring at the end face of the frame;
[0022] When the end face of the window assembly contacts and seals with the side wall surface of the high-voltage cabinet, the frame and the side wall of the high-voltage cabinet can compress the sealing ring, causing it to deform.

[0026] The high-voltage switchgear observation window provided by this utility model has at least the following advantages compared with the prior art:
[0027] 1. By setting up a track and an electric push rod, the electric push rod can move the window assembly along a fixed track, so that the observation window is in an unobstructed state, avoiding the problem of not being able to clearly observe the inside of the high-voltage cabinet due to the decrease in the light transmittance of the window assembly.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0045] The core of this utility model is to provide a high-voltage switchgear observation window. The window assembly is moved by an electric push rod, so that the observation window is in an unobstructed state. This effectively solves the problems of unclear observation caused by the decrease in the light transmittance of the window assembly and inaccurate temperature measurement caused by the obstruction of the window assembly. At the same time, a face recognition module is added to control whether the observation window is opened by verifying user permissions, so as to avoid safety accidents caused by the opening of the observation window.
[0046] Another core aspect of this utility model is to provide a high-voltage switchgear that includes the observation window of the aforementioned high-voltage switchgear, which has the same technical solution and can solve the same technical problem.
[0047] Please refer to Figures 1-4 A high-voltage switchgear observation window, comprising:
[0048] Window assembly 6 is used to cover the observation window of the high-voltage switchgear;
[0049] The electric push rod 52 is electrically connected to the control module 8, with one end fixedly connected to the high-voltage cabinet and the other end fixedly connected to the window assembly 6. It is used to drive the window assembly 6 to slide along the feed direction of the track 7.
[0050] The video acquisition module 2 includes a face recognition module, which is electrically connected to the control module 8. It is used to record and detect the user's permissions to determine whether to control the electric push rod 52.
[0051] like Figure 1 and Figure 4As shown, the window assembly 6 is used to cover the observation window, thus sealing the high-voltage cabinet at the observation window position. Then, the electric push rod 52 is used to drive the window assembly 6 to slide along the track 7. When the window assembly 6 moves to a set position within the track 7, the window assembly 6 can complete the covering and sealing of the observation window. When the electric push rod 52 drives the window assembly 6 to other positions within the track 7, the observation window is in an uncovered state, so that the user can clearly observe the internal situation of the high-voltage cabinet through the observation window and can use a handheld thermometer to detect the internal temperature of the high-voltage cabinet.
[0052] However, when the observation window is unobstructed, the internal environment of the high-voltage cabinet is directly connected to the external environment, which may lead to leakage of internal media. Therefore, the window assembly 6 needs to be opened under the monitoring of specific users. Therefore, a video acquisition module 2 is added to record all users who operate or pass through the observation window, and the internal face recognition module is used to detect user permissions. When it is detected that the current user has the permission to open the window, the control module 8 sends a command to control the electric push rod 52 to move the window assembly 6, that is, to open the observation window. When it is detected that the current user does not have the permission, the observation window will not be opened.
[0053] Furthermore, when the video acquisition module 2 detects that the user has left, it sends a command again through the control module 8 to control the electric push rod 52 to drive the window assembly 6 to reset, thus completing the re-closing of the observation window.
[0054] In some embodiments, the observation window of the high-voltage switchgear also includes a temperature and humidity monitoring module 3 and a display module 12 electrically connected to the control module 8;
[0055] Temperature and humidity monitoring module 3 is arranged inside or outside the high-voltage cabinet to detect the temperature and humidity at its installation location;
[0056] The display module 12 is located outside the high-voltage cabinet and is used to display the measurement data of the temperature and humidity monitoring module 3 and / or the current stroke position of the electric push rod 52.
[0057] like Figure 4 As shown, by setting a temperature and humidity monitoring module 3 inside the high-voltage cabinet, the temperature and humidity inside the high-voltage cabinet can be directly monitored, and the monitoring results can be directly displayed through the display module 12 outside the high-voltage cabinet. Thus, when measuring the temperature and humidity inside the high-voltage cabinet, there is no need to open the observation window, which avoids leakage of the medium inside the high-voltage cabinet and ensures accurate monitoring of the temperature and humidity inside the high-voltage cabinet.
[0058] Meanwhile, when the temperature and humidity monitoring module 3 detects that the temperature and humidity inside the high-voltage cabinet are not suitable for opening the observation window, it can also send a command to the control module 8. That is, after the control module 8 comprehensively analyzes the temperature and humidity inside the high-voltage cabinet and the user's permissions, it will send the relevant command only when both meet the conditions for opening the observation window. Otherwise, it will not send the command to open the observation window to avoid causing work accidents. At the same time, the reason and result of not opening the window will be displayed through the display module 12.
[0059] Meanwhile, the display module 12 can also be used to display the current travel position of the electric actuator 52, that is, to intuitively display the current open and closed state of the observation window.
[0060] In some embodiments, the display module 12 is a touch screen 1, and the touch screen 1 integrates an operation module 11 for manually controlling the movement of the electric push rod 52.
[0061] like Figure 4 As shown, the display module 12 uses a touch screen 1 and integrates an operation module 11. It can send control commands to the control module 8 to control the electric push rod 52 by manually inputting commands, thus realizing another way to open the observation window.
[0062] In some embodiments, the high-voltage switchgear observation window also includes an illumination module 51 electrically connected to the control module 8, which is arranged inside or outside the high-voltage switchgear to illuminate its installation location.
[0063] like Figure 4 As shown, a lighting module 51 is added inside and / or outside the high-voltage cabinet. The lighting module 51 and the electric push rod 52 together form an execution terminal 5, which executes relevant actions by receiving instructions from the control module 8. For example, when the video acquisition module 2 detects that a person is passing in front of the observation window, it controls the lighting module 51 outside the high-voltage cabinet to light up for supplementary lighting. When the face recognition module detects that the person has user permissions, or the person inputs relevant instructions through the operation module 11, it controls the lighting module 51 inside the high-voltage cabinet to light up for supplementary lighting inside the high-voltage cabinet.
[0064] In some embodiments, the high-voltage switchgear observation window also includes a communication module 4 electrically connected to the control module 8, for communicating with the user's mobile terminal wirelessly to send control commands to the control module 8 or receive information stored in the control module 8.
[0065] like Figure 4As shown, the integrated communication module 4, such as a Bluetooth mesh module, has wireless transmission capabilities and can interact with the user's mobile terminal to transmit the travel position information of the electric push rod 52, the lighting information of the lighting module 51, and the monitoring information of the temperature and humidity monitoring module 3 to the user's mobile terminal, so as to facilitate timely understanding of the situation inside the high-voltage cabinet; and the user can send relevant commands to the control module 8 through the mobile terminal to control the electric push rod 52 and the lighting module 51 to perform corresponding actions.
[0066] In some embodiments, the track 7 includes a long straight section 71 and a bent section 72 connected together, the bent section 72 being bent toward the sealing surface that contacts and seals the high-voltage cabinet and the window assembly 6.
[0067] When the window assembly 6 slides into the bending section 72, the end face of the window assembly 6 contacts and seals with the side wall surface of the high-voltage cabinet.
[0068] like Figures 1-3 As shown, the track 7 adopts a design that combines a long straight section 71 and a bent section 72. When the observation window is in the closed state, the window assembly 6 is located within the bent section 72, thereby reducing the distance between the window assembly 6 and the side wall of the high-voltage cabinet, which helps to improve the sealing of the contact position between the two. When the observation window is in other states, the window assembly 6 is located within the long straight section 71, that is, there is a large gap between the window assembly 6 and the side wall of the high-voltage cabinet, avoiding contact wear between the two.
[0069] In some embodiments, the window assembly 6 includes a transparent plate, a frame 61 surrounding the transparent plate, and a sealing ring 63 at the end face of the frame 61.
[0070] When the end face of the window assembly 6 contacts and seals with the side wall surface of the high-voltage cabinet, the frame 61 and the side wall of the high-voltage cabinet can squeeze the sealing ring 63, causing it to deform.
[0071] like Figure 1 As shown, a sealing ring 63 is provided on the end face of the frame 61. When the window assembly 6 is in the bending section 72, the frame 61 and the side wall of the high-voltage cabinet simultaneously squeeze the sealing ring 63, causing it to deform and seal. When the observation window is opened, the window assembly 6 enters the long straight section 71. At this time, the distance between the frame 61 and the side wall of the high-voltage cabinet increases, and the sealing ring 63 separates from the side wall of the high-voltage cabinet, avoiding the decrease in sealing performance caused by long-term wear of the sealing ring 63.
[0072] In some embodiments, sliders are provided at both ends of the frame 61, and the sliders are slidably mounted to the track 7;
[0073] A hinge seat 62 is provided on the side of the frame 61. The hinge seat 62 is hinged to the end of the electric push rod 52 through the connecting rod 64. The feed direction of the electric push rod 52 is consistent with the feed direction of the long straight section 71.
[0074] like Figure 2 As shown, a hinge seat 62 is provided on the frame 61, and the end of the electric push rod 52 and the hinge seat 62 are connected by a connecting rod 64. Both ends of the connecting rod 64 are connected in the form of hinges, which can solve the problem that the movement trajectory of the window assembly 6 in the bending section 72 is inconsistent with the feed direction of the electric push rod 52, thereby ensuring the smooth movement of the window assembly 6.
[0075] In addition to the high-voltage switchgear observation window disclosed in the above embodiments, this utility model also provides a high-voltage switchgear including the above-mentioned high-voltage switchgear observation window. For the structure of other parts of the high-voltage switchgear, please refer to the prior art, which will not be described in detail here.
[0076] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0077] The above provides a detailed description of the high-voltage switchgear observation window and the high-voltage switchgear itself provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
