[0002] High and low voltage power distribution equipment is a combination of devices used in power systems to receive, distribute, control, and protect electrical energy. It typically includes high-voltage and low-voltage switchgear, transformers, distribution boxes, and other equipment, and is a vital component of power systems. To ensure the safety of high and low voltage power distribution equipment during use, remote automatic maintenance devices for high and low voltage power distribution equipment are now available on the market. These devices replace traditional manual maintenance methods, improve maintenance efficiency and reliability, and ensure the safe and stable operation of power systems.

[0003] In today's power sector, the stable operation of high and low voltage complete sets of distribution equipment is of vital importance. With the continuous development of science and technology, remote monitoring and maintenance technology has gradually become a key means to ensure the normal operation of distribution equipment. The remote maintenance devices for high and low voltage complete sets of distribution equipment on the market usually have remote monitoring, fault diagnosis, remote control, alarm, data storage and analysis, communication, compatibility and other functions, which can improve maintenance efficiency, ensure the safe operation of the power system, and remote maintenance devices.

[0004] In order to meet the space requirements, the operation panels of existing remote maintenance devices are mostly configured to accommodate only a keyboard and a mouse, resulting in a relatively small operating space. Maintenance personnel usually carry items such as notebooks for recording. When operating the keyboard and mouse, it is not only inconvenient for the personnel to operate the mouse, but the notebooks carried by the personnel also need to be placed elsewhere or tucked under their arms. When recording data, they need to place them on the outer wall of the device to record data, making the device relatively inconvenient to use. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a remote maintenance device for high and low voltage complete sets of power distribution equipment to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a remote maintenance device for a high and low voltage complete set of power distribution equipment, comprising a device body, an operation box slidably mounted in the device body, and an expansion mechanism provided on the operation box;

[0020] By adopting the above technical solution, the operation box is restricted by the slide bar and the installation slot when sliding, thereby ensuring the stability of the operation box when sliding.

[0021] Furthermore, a positioning block that is in contact with the outer wall of the operation box is threadedly mounted on the outer end of the slide rod, and the installation positions of the slide rod and the positioning block are staggered with the installation position of the extension plate.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] A remote maintenance device for high and low voltage complete sets of power distribution equipment, such as Figure 1 - Figure 6 As shown, the device comprises a main body 1, in which an operation box 2 for placing a keyboard and a mouse is slidably installed. When in use, the user pulls the operation box 2 outward to expose the keyboard and the mouse, and the user can remotely monitor and maintain the power distribution equipment by operating the keyboard and the mouse.

[0035] In this embodiment, an expansion mechanism is provided on the operation box 2, and the expansion mechanism includes an extension plate 4 arranged on the outside of the operation box 2. At the same time, a support rod 5 is fixedly installed on the outer wall of the extension plate 4, and the support rod 5 is slidably connected to the operation box 2. The extension plate 4 is slidably connected to the operation box 2 through the support rod 5, so that the extension plate 4 will be supported by the operation box 2, and because a spring 6 corresponding to the support rod 5 is installed in the operation box 2, when the extension plate 4 loses its restriction, the spring 6 will push the extension plate 4 outward through the support rod 5, thereby ensuring that the use area of ​​the operation box 2 is expanded.

[0036] It should be noted that a mounting groove 21 corresponding to the operation box 2 is provided in the device body 1, and a slide bar 3 slidably connected to the operation box 2 is installed in the mounting groove 21, so that the operation box 2 is restricted by the slide bar 3 and the mounting groove 21 when sliding, ensuring the stability of the operation box 2 when sliding;

[0037] At the same time, a positioning block is threadedly installed on the outer end of the slide rod 3, which is in contact with the outer wall of the operation box 2. When the operation box 2 has a problem and needs to be maintained or replaced, the restriction imposed by the positioning block on the operation box 2 can be released by rotating the positioning block, and the operation box 2 can be directly slid out. The installation positions of the slide rod 3 and the positioning block are staggered with the installation position of the extension plate 4, ensuring that the settings of the positioning block and the slide rod 3 will not interfere with the extension plate 4.

[0038] See also Figure 2 - Figure 6 In this embodiment, the extension plates 4 are symmetrically installed on both sides of the operation box 2, so that the usable area on both sides of the operation box 2 is increased, further ensuring that when the device is in use, the user can place items such as notebooks on the device;

[0039] It should also be noted that when the operation box 2 is located in the device body 1, the outer wall of the extension plate 4 and the outer wall of the operation box 2 are located on the same vertical line to ensure that the setting of the extension plate 4 will not cause the operation box 2 to be unable to re-enter the device body 1.

[0040] For further information, see Figure 6In this embodiment, the cross-section of the extension plate 4 is designed to be inverted L-shaped, and the extension plate 4 is rotatably installed with multiple sets of buffer wheels 44 close to the outer wall of the device main body 1. When the operation box 2 is pulled out, the outer wall of the buffer wheel 44 is in contact with the outer wall of the device main body 1, so that when the extension plate 4 slides outward, the buffer wheel 44 will reduce the friction between it and the outer wall of the device main body 1. At the same time, because the multiple sets of buffer wheels 44 will be in contact with the inner wall of the device main body 1, the buffer wheels 44 will cooperate with the outer wall of the device main body 1 to support the extension plate 4, so that the extension plate 4 will also support the operation box 2 when in use, thereby improving the stability of the operation box 2 during use and reducing the probability of it tilting downward after being compressed.

[0041] See also Figure 4 - Figure 6 In this embodiment, two sets of racks 41 are slidably installed in the operation box 2. The two sets of racks 41 are connected to the outer wall of a set of extension plates 4, so that the extension plates 4 will drive the racks 41 to slide synchronously when sliding. At the same time, the installation positions of the two sets of racks 41 are staggered to avoid mutual interference between the racks 41, ensuring that the racks 41 can slide smoothly. In addition, a gear 42 meshing with the two sets of racks 41 is rotatably installed in the operation box 2, so that the racks 41 will drive the gear 42 to rotate when sliding, so that the two sets of racks 41 will slide synchronously. A movable groove 43 corresponding to the rack 41 is opened in the operation box 2.

[0042] See also Figure 5 and Figure 6 In this embodiment, two groups of support grooves 7 symmetrically connected to the support rod 5 are provided in the operation box 2, and the cross section of the support rod 5 is designed in a "cross" shape. When the support rod 5 slides, the support groove 7 will limit and support the support rod 5 to ensure the sliding stability of the support rod 5. Moreover, because the maximum diameter of the support rod 5 in the support groove 7 is larger than the diameter of the opening of the support groove 7, the support rod 5 cannot slide out of the support groove 7, so that the sliding distance of the extension plate 4 will be limited, thereby preventing the extension plate 4 from separating from the operation box 2.

[0043] It should be noted that, in this embodiment, the spring 6 is sleeved on the outer wall of the support rod 5, so that the spring 6 will be restricted by the support rod 5, avoiding the probability of deformation of the spring 6. At the same time, because one end of the spring 6 is connected to the end of the support rod 5 and the other end is connected to the inner wall of the support groove 7, when the extension plate 4 slides toward the support groove 7, the support rod 5 will squeeze the spring 6, so that the spring 6 is in a compressed state, thereby ensuring that when the operating box 2 is pulled out, the spring 6 will push the support rod 5, so that the extension plate 4 will slide outward.

[0044] The working principle of the present invention is as follows: when the device needs to be used, the operation box 2 is first pulled outward to make the operation box 2 slide outward. When the end of the operation box 2 slides out of the mounting slot 21, the two sides of the extension plate 4 lose their restrictions. At this time, the spring 6 pushes the support rod 5 outward, causing the extension plate 4 to slide outward. At this time, the outer wall of the buffer wheel 44 is in contact with the outer wall of the device body 1. At this time, the extension plate 4 is supported by the buffer wheel 44, so that the extension plate 4 is supported after sliding outward. At the same time, the user can operate the mouse on the extension plate 4 on one side and can also place items such as a notebook on the extension plate 4 on the other side, making the device more convenient to use.

[0045] When the operation box 2 needs to be retracted, the extension plate 4 is pushed, so that the extension plate 4 drives the rack 41 to slide, prompting the gear 42 to start rotating, driving the other set of extension plates 4 to move synchronously, so that the two sets of extension plates 4 are reset synchronously.

[0046] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
