Abstract
Description
Technical Field
[0001] This application relates to the field of grounding boxes, and more particularly to a cross-connection protective grounding box. Background Technology
[0002] Cross-connection protection grounding boxes are key equipment in power systems used for cross-connection grounding of cable lines. Their main function is to ensure that the metal sheath of the cable is at a suitable potential during normal operation, so as to avoid endangering equipment and personnel safety due to excessive induced voltage. At the same time, they can effectively achieve grounding protection and prevent the fault from spreading when a cable fault occurs.
[0003] Currently, with the continuous development of power systems, the requirements for the safety and stability of cable lines are increasing, and the application of cross-interconnection protective grounding boxes is becoming more and more widespread. However, existing cross-interconnection protective grounding boxes have some problems that urgently need to be solved. Among them, the limited internal space of the grounding box is a particularly prominent issue. In actual use, when long grounding wires need to be placed, due to the unreasonable internal space layout of the box, the grounding wires often end up in a messy and tangled state. This messy wiring not only affects the overall efficiency of wiring, making it difficult to quickly and accurately locate the required wiring when operating the grounding box, increasing operation time and difficulty; but it also has a certain negative impact on subsequent maintenance of the grounding box. During maintenance, messy wiring may cover up some potential fault points, making it difficult for maintenance personnel to comprehensively and accurately troubleshoot problems, prolonging maintenance time, and even failing to completely resolve the hidden dangers of the grounding box due to misjudgment, thereby affecting the safe and stable operation of the power system.
[0004] Regarding the aforementioned technologies, the inventors believe that grounding boxes have the drawback of making it inconvenient to organize the wiring during use. Therefore, they have proposed a cross-interconnection protective grounding box to solve the above problems. Utility Model Content
[0005] To address the issue of inconvenient wiring organization during the use of grounding boxes, this application provides a cross-interconnection protective grounding box.
[0006] The cross-interconnection protective grounding box provided in this application adopts the following technical solution:
[0007] A cross-interconnection protective grounding box includes a box body. A fixed inner cavity is formed in the middle of the front face of the box body. Several fixed pipes are fixedly connected to the bottom of the inner wall of the box body extending to the outside of the box body. A fixed partition is fixedly installed at the bottom of the inner wall of the box body. Several fixed holes are formed on the upper surface of the fixed partition. A bearing support is fixedly installed on one side of the inner wall of the fixed inner cavity near the bottom of the fixed partition. A support rod is rotatably installed inside the bearing support. A limit screw is threadedly connected at a position symmetrical to the bearing support on the outer surface of the box body. One side of the limit screw extends into the fixed inner cavity and is fixedly connected to a limit sleeve. A partition component is also provided between the fixed inner cavity and the fixed partition for dividing the bottom space inside the fixed inner cavity.
[0008] Preferably, the partition assembly includes several fixed guide rails, which are symmetrically and parallelly fixed to the bottom surface of the fixed partition and the bottom end of the inner wall of the fixed cavity. A movable baffle is movably installed between two symmetrical fixed guide rails, and a notch is opened on one side of the movable baffle on the outer surface of the support rod.
[0009] Preferably, a fixing groove is provided in the middle of one side of the limiting sleeve, the outer diameter of the support rod is smaller than the inner diameter of the fixing groove, one side of the support rod is located inside the fixing groove, and the support rod and the fixing groove are engaged with each other.
[0010] Preferably, the length of the support rod is less than the distance between the two sides of the inner wall of the fixed cavity, and the support rod is located in the middle of the fixed cavity and the fixed partition.
[0011] Preferably, the movable baffle is fixedly connected to the upper and lower ends with limiting protrusions, and the fixed guide rail is provided with a guide groove inside, with the limiting protrusions located inside the guide groove, and the limiting protrusions and the guide groove interlocking with each other.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] By incorporating a partitioning component, the bottom space within the fixed cavity can be flexibly divided using fixed guide rails and movable baffles, providing a convenient foundation for wiring organization. Simultaneously, the rotatable design of the support rod greatly enhances the flexibility and efficiency of wiring organization. In practice, the support rod can be rotated to separate it from the limiting sleeve and removed. Different grounding wires can then be orderly wound onto the support rod, achieving initial wiring organization. Subsequently, the support rod with the grounding wires wound can be placed back between the fixed cavity and the fixed partition. By rotating the support rod, the movable baffle can be slid within the fixed guide rail using the notch on one side, dividing the bottom space within the fixed cavity into different areas. The organized wiring can then be placed in the corresponding areas, effectively preventing the grounding wires from tangling and significantly improving the overall efficiency of wiring use.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0019] This application discloses a cross-interconnection protective grounding box. (Refer to...) Figure 1-3 A cross-interconnection protective grounding box includes a box body 1. A fixed inner cavity 2 is formed in the middle of the front face of the box body 1. Several fixed pipes 3 are fixedly connected to the bottom of the inner wall of the box body 1 extending to the outside of the box body 1. A fixed partition 4 is fixedly installed at the bottom of the inner wall of the box body 1. Several fixed holes 5 are formed on the upper surface of the fixed partition 4. A bearing support 6 is fixedly installed on one side of the inner wall of the fixed inner cavity 2 near the bottom of the fixed partition 4. A support rod 7 is rotatably installed inside the bearing support 6. The length of the support rod 7 is less than the distance between the two sides of the inner wall of the fixed inner cavity 2. The support rod 7 is located in the fixed inner cavity 2. At the midpoint between the fixed partition 4 and the outer surface of the housing 1, a limit screw 8 is threadedly connected to the bearing support 6 at a position symmetrical to the outer surface of the housing 1. One side of the limit screw 8 extends into the fixed inner cavity 2 and is fixedly connected to a limit sleeve 9. A fixed slot 10 is provided in the middle of one side of the limit sleeve 9. The outer diameter of the support rod 7 is smaller than the inner diameter of the fixed slot 10. One side of the support rod 7 is located inside the fixed slot 10. The support rod 7 and the fixed slot 10 are engaged with each other. A partition assembly is also provided between the fixed inner cavity 2 and the fixed partition 4 to separate the bottom space inside the fixed inner cavity 2.
[0020] Remove the support rod 7 by rotating it. Wrap different grounding wires around the support rod 7 in a certain order to complete the initial wiring arrangement. Place the support rod 7 with the grounding wires wrapped back between the fixed inner cavity 2 and the fixed partition 4. Rotate the limiting screw 8 so that the fixing groove 10 on the limiting sleeve 9 engages with one side of the support rod 7 to fix the position of the support rod 7.
[0021] Reference Figure 2 and Figure 3The partition assembly includes several fixed guide rails 11, which are symmetrically and parallelly fixed to the bottom surface of the fixed partition plate 4 and the bottom end of the inner wall of the fixed inner cavity 2. A movable baffle 12 is movably installed between two symmetrical fixed guide rails 11. One side of the movable baffle 12 is located on the outer surface of the support rod 7 and has a notch 13. Limiting protrusions are fixed to both the upper and lower ends of the movable baffle 12. A guide groove is opened inside the fixed guide rail 11, and the limiting protrusion is located inside the guide groove. The limiting protrusion and the guide groove are interlocked.
[0022] The limiting protrusions at the upper and lower ends of the movable baffle 12 engage with the guide groove inside the fixed guide rail 11. Therefore, when the support rod 7 rotates, it will push the movable baffle 12 to slide smoothly inside the fixed guide rail 11 through the notch groove 13, thereby dividing the bottom space inside the fixed inner cavity 2 into different areas.
[0023] The implementation principle of a cross-interconnection protective grounding box according to an embodiment of this application is as follows: When using the cross-interconnection protective grounding box, first rotate the limiting screw 8 to separate the limiting sleeve 9 from the support rod 7, and then rotate and remove the support rod 7. Different grounding wires are wound onto the support rod 7 in a certain order to complete the initial wiring arrangement.
[0024] Next, the support rod 7 with the grounding wire wound around it is placed back between the fixed inner cavity 2 and the fixed partition 4. Rotating the support rod 7 causes the movable baffle 12 to rotate. Since the movable baffle 12 has a notch 13 on one side that mates with the support rod 7, and the limiting protrusions at the upper and lower ends of the movable baffle 12 engage with the guide groove inside the fixed guide rail 11, the rotation of the support rod 7 will push the movable baffle 12 to slide smoothly within the fixed guide rail 11 through the notch 13, thus dividing the bottom space inside the fixed inner cavity 2 into different areas.
[0025] Continue rotating the limiting screw 8 until the fixing groove 10 on the limiting sleeve 9 engages with one side of the support rod 7, fixing the position of the support rod 7 and thus fixing the position of the movable baffle 12, completing the separation of the wiring space. At this time, the grounding wires wrapped around the support rod 7 are separated and placed in their respective areas, avoiding mutual entanglement.
[0026] When subsequent adjustments or maintenance of the wiring are required, rotate the limit screw 8 again to separate the limit sleeve 9 from the support rod 7, and then rotate the support rod 7 to adjust the position of the movable baffle 12 for easy viewing and operation of the internal wiring.
