Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable grounding box technology, specifically a cable grounding box that is easy to maintain. Background Technology
[0002] High-voltage cable outer sheath grounding methods typically include double-sided grounding, single-sided grounding, and cross-interconnected grounding. Double-sided grounding uses direct grounding boxes on both sides; single-sided grounding uses a protective grounding box on one side and a direct grounding box on the other; and cross-interconnected grounding uses a cross-interconnected box at the two middle joints and direct grounding boxes at both ends. Therefore, in practical production, this is equivalent to three types of grounding boxes: direct grounding boxes, protective grounding boxes, and three-phase cross-interconnected grounding boxes.
[0003] Cable grounding boxes are widely used in various environments to protect cables. However, to ensure safety and reasonable space, most grounding boxes are made of metal welded together, and the rest of the boxes are sealed except for the sliding door. Although this type of box is safe and convenient to use, it is more difficult to install and maintain. For example, after a long period of use, cables and internal components will age and accumulate dust. In addition, the internal space of the box is small, and when workers perform maintenance, they not only need to clean but also need to carefully identify and operate, which increases the difficulty of maintenance.
[0004] Therefore, a new type of cable grounding box that is easy to maintain and can temporarily expand space is now being designed to address these shortcomings. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cable grounding box that is easy to maintain, solving the problem of inconvenient maintenance of existing cable grounding boxes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable grounding box with convenient maintenance, comprising a U-shaped frame, wherein the front and rear parts of the bottom sides of the U-shaped frame are fixedly connected to a first sliding frame by fixing blocks, an L-shaped sliding rod is slidably installed on the inner side of the first sliding frame, and a side sealing plate for cooperating with the U-shaped frame is fixedly connected between the top ends of the two L-shaped sliding rods on the same side, the bottom of the U-shaped frame is fixedly connected to a second sliding frame, a guide plate is slidably installed on the inner side of the second sliding frame, the front end of the guide plate is rotatably connected to a front sealing plate for cooperating with the U-shaped frame and the side sealing plate by a rotating component, a copper busbar assembly is fixedly installed on the rear part of the inner cavity of the U-shaped frame by a bracket, and a terminal block is fixedly installed on the bottom of the U-shaped frame by opening an opening.
[0007] Preferably, the surface of the first sliding frame is provided with a first insertion port extending to the rear, and the first insertion ports at the front and rear are staggered. Both the front and rear L-shaped sliding rods are provided with a second insertion port that cooperates with the first insertion port.
[0008] Preferably, the front and rear parts of both sides of the guide plate are fixedly connected with horizontal tie rods, and the two ends of the horizontal tie rods at the front and rear are respectively fixedly connected with a first insert block and a second insert block.
[0009] Preferably, the lower part of both sides of the U-shaped frame surface is provided with irregular sliding grooves, and an L-shaped support plate that cooperates with the first insert block is slidably installed on the inner side of the irregular sliding groove. A spring is fixedly connected between the rear part of the L-shaped support plate and the inner wall of the irregular sliding groove.

[0011] Beneficial effects
[0012] This invention provides a cable grounding box that is easy to maintain. Compared with existing technologies, it has the following advantages:
[0013] (1) The cable grounding box with convenient maintenance has a first sliding frame installed on both sides of the bottom of the U-shaped frame, and a side sealing plate that works with the U-shaped frame is installed using an L-shaped sliding rod. It is used in conjunction with the front sealing plate, the first plug and the second plug. The structure can open the sides and front of the U-shaped frame during maintenance, thereby exposing the internal cables and parts, increasing the operating space and facilitating maintenance procedures. In addition, the first plug and the second plug, together with the first plug and the second plug, can ensure the stability of the side sealing plate during maintenance, which is convenient for use.
[0014] (2) The cable grounding box with convenient maintenance has an L-shaped support plate installed on the surface of the U-shaped frame through a special-shaped sliding groove, which is used in conjunction with the front cover plate. It is used with springs and horizontal tie rods. The structure can push the L-shaped support plate out when the front cover plate pulls the horizontal tie rod, so that the front cover plate can be flipped over for load-bearing connection. This allows the staff to place maintenance tools on top of it, effectively increasing the functionality of the equipment. Attached Figure Description

[0022] 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.
[0023] Please see Figure 1-6 This utility model provides a technical solution: a cable grounding box with convenient maintenance, including a U-shaped frame 1. A first sliding frame 2 is fixedly connected to the front and rear of both sides of the bottom of the U-shaped frame 1 via fixing blocks. An L-shaped sliding rod 3 is slidably installed on the inner side of the first sliding frame 2. A side sealing plate 4, which cooperates with the U-shaped frame 1, is fixedly connected between the tops of the two L-shaped sliding rods 3 on the same side. The edge of the side sealing plate 4 is wrapped with a rubber layer to improve sealing. A second sliding frame 5 is fixedly connected to the bottom of the U-shaped frame 1. A guide plate 15 is slidably installed on the inner side of the second sliding frame 5. The front end of the guide plate 15 is rotatably connected to the U-shaped frame 1 and the side sealing plate 4 via a rotating component. The front sealing plate 6 is used in conjunction with the copper busbar assembly 17 fixedly installed at the rear of the inner cavity of the U-shaped frame 1 by a bracket. The bottom of the U-shaped frame 1 is fixedly installed with a junction box 18 through an opening. The edge of the front sealing plate 6 is wrapped with a rubber layer to improve the sealing performance. The upper part of the surface of the U-shaped frame 1 is fixedly connected with a lock cylinder 16 that works with the front sealing plate 6 by a fixing plate. The lock cylinder 16 is pre-installed and can be used with the front sealing plate 6. The surface of the first sliding frame 2 has a first insertion port 7 that extends to the rear. The first insertion ports 7 at the front and rear are staggered. The L-shaped slide rods 3 at the front and rear both have a second insertion port 8 that works with the first insertion port 7.
[0024] In use, the U-shaped frame 1 is pre-installed in the designated position. When maintenance is required, the front sealing plate 6 is unlocked by inserting the key into the lock cylinder 16. Then, the front sealing plate 6 is pulled forward under the limit of the guide plate 15. When the front sealing plate 6 moves forward, the second insert 10 is pulled out from the inside of the first insert 7 and the second insert 8 at the front. At this time, the first insert 9 just touches the first sliding frame 2 and is not inserted. Then, the side sealing plate 4 is pulled away from both sides under the limit of the first sliding frame 2, exposing both sides of the U-shaped frame 1. When the side sealing plate 4 is pulled open, the second insert 8 at the rear coincides with the first insert 7 at the rear. At this time, the front sealing plate 6 is pulled again so that the front sealing plate 6 inserts the first insert 9 at the rear into the inside of the first insert 7 and the second insert 8 at the rear through the guide plate 15. At this time, the side sealing plate 4 is fixed.
[0025] Furthermore, horizontal tie rods 14 are fixedly connected to the front and rear of both sides of the guide plate 15. The first insert 9 and the second insert 10 are fixedly connected to the two ends of the front and rear horizontal tie rods 14, respectively. Irregular grooves 11 are opened on the lower part of both sides of the surface of the U-shaped frame 1. An L-shaped support plate 12 that cooperates with the first insert 9 is slidably installed on the inner side of the irregular groove 11. A spring 13 is fixedly connected between the rear of the L-shaped support plate 12 and the inner wall of the irregular groove 11.
[0026] At the same time, when the guide plate 15 is pulled, the horizontal tie rod 14 will also push the L-shaped tray 12 out from the inside of the irregular slide groove 11. After the L-shaped tray 12 is pushed out, the front cover plate 6 is flipped so that it rests on the top of the L-shaped tray 12. Then maintenance work is carried out, and the cable is inserted from the junction box 18 to connect with the copper busbar assembly 17.
[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
