Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a cable lead-in protection tube. Background Art

[0002] Cable uplinks are the sections of cable that extend upward from ground-level distribution facilities, running along poles, walls, or supports to connect to overhead lines or other electrical equipment. They are a crucial transitional link in power systems, connecting underground cables to above-ground lines or equipment. They typically utilize power cables with high insulation and mechanical strength, along with appropriate anchoring, protection, and grounding measures.

[0003] Traditional protective measures mostly use a single and fixed protective tube. This type of protection has a single function and limited protection performance. When facing external impact, it is easy to cause damage to the protective tube and the cable lead-in line.

[0004] Therefore, it is necessary to design a cable lead-in protection tube. Utility Model Content

The protective inner layer is arranged on the inner side of the protective outer layer and the protective inner layer is spaced apart from the protective outer layer.

[0008] In one embodiment, a reflective tape is provided on a side of the protective outer layer facing away from the protective inner layer.

[0009] In one embodiment, a protective cover is provided on the top of the tubular structure formed by the two protective plates.

[0010] In one embodiment, a sealing rubber ring is fixedly connected to the interior of the protective cover, and the sealing rubber ring is a water-swelling rubber ring.

[0011] In one embodiment, a limiting rod is fixedly connected to the bottom of the protective cover, and the limiting rod is used to be inserted into the gap between the protective inner layer and the protective outer layer.

[0012] In one embodiment, an indicator block is fixedly connected to the outer side wall of the protective cover.

[0013] In one embodiment, a connecting piece is provided on the outer wall of each protective plate, and a connecting hole is opened on the connecting piece. The fastening screw passes through the two connecting holes in sequence and is threadedly connected with the nut, so that the two protective plates can be connected by the fastening screw.

[0028] A cable lead protection tube, such as Figure 1-Figure 2As shown, it includes a protective plate 1, a protrusion 101, a spring 3 and an arc-shaped rubber plate 4. The opposite ends of the protective plate 1 are respectively provided with a protrusion 101 and a slot 102. There are two protective plates 1. The protrusion 101 of one protective plate 1 is used to plug and cooperate with the slot 102 of the other protective plate 1, so that the two ends of one protective plate 1 are plugged into the two ends of the other protective plate 1 one by one, and the two protective plates 1 can be enclosed to form a tubular structure. One end of the spring 3 is fixedly connected to the inside of the protective plate 1, and the end of the spring 3 away from the protective plate 1 is fixedly connected to the arc-shaped rubber plate 4.

[0029] The present invention provides two protective plates 1, so that the two protective plates 1 can form a tubular structure by plugging and fitting the slots 102 and the protrusions 101 between each other to protect the cable lead-in line inside, thereby forming a first layer of protection; and at least one arc-shaped rubber plate 4 is provided inside each protective plate 1, and each arc-shaped rubber plate 4 is connected to the corresponding protective plate 1 through a spring 3, and the number of arc-shaped rubber plates 4 is consistent with the number of springs 3 and is provided in a one-to-one correspondence; by providing the springs 3 and the arc-shaped rubber plates 4, when the protective plate 1 is impacted by an external force, the spring 3 will convert the rigid impact into a flexible impact and act on the cable lead-in line through the arc-shaped rubber plate 4, thereby avoiding the rigid impact directly acting on the cable lead-in line and causing the cable lead-in line to be damaged; due to the buffering of the spring 3, a second layer of protection is formed, so that the protective plate 1 is When impacted by the outside world, the cable lead-in wire located inside it is not easily damaged; and the present embodiment adopts an arc-shaped rubber plate 4, which, on the one hand, can fit the cable lead-in wire more closely in shape, avoiding its shape being too sharp and scratching the cable lead-in wire, further reducing the probability of damage to the cable lead-in wire; on the other hand, the arc-shaped rubber plate 4 adopted in the present embodiment has a certain elasticity, and its material can be made of existing materials, such as polyurethane, etc. The arc-shaped rubber plate 4 with a certain elasticity can also play a certain buffering role against external impact, reduce the destructive force of external impact on the cable lead-in wire, and thus reduce the probability of damage to the cable lead-in wire; therefore, a third layer of protection is formed by arranging the arc-shaped rubber plate 4; through the three-layer protection, the cable lead-in wire is effectively protected, so that the cable lead-in wire is not easily damaged when the protective plate 1 is impacted.

[0030] In one embodiment, the protective plate 1 includes a protective inner layer, a protective outer layer, and a partition connecting the protective inner layer and the protective outer layer. The protective inner layer is arranged on the inner side of the protective outer layer and the protective inner layer and the protective outer layer are spaced apart. This arrangement can also play a certain buffering role against external impacts, reduce the destructive force of external impacts on the cable lead-in wire, and thus reduce the probability of damage to the cable lead-in wire. It should be noted that its buffering principle is that when subjected to external impact, the partition will undergo buckling deformation. This buckling process will absorb part of the energy, thereby reducing the destructive force of external impacts on the cable lead-in wire; and the partition forms multiple force transmission paths. When subjected to external force, the force can be transmitted through these complex paths. Compared with a single solid structure, this multi-path force transmission method enables stress to be distributed and transmitted through different force transmission path elements, reduces local stress concentration, and improves the impact resistance of the structure, so that the cable lead-in wire is not easily damaged by external impact.

[0031] like Figure 1 As shown, a reflective tape 2 is provided on the side of the protective outer layer away from the protective inner layer. The design of the reflective tape 2 can effectively attract pedestrians or vehicles to achieve a warning effect, thereby preventing pedestrians or vehicles from hitting the device and ensuring the safety of the device and the cable lead-in line.

[0032] like Figure 1-Figure 2 As shown, a protective cover 8 is provided on the top of the tubular structure formed by the two protective plates 1. Connectors 5 are provided on the outer walls of each protective plate 1. The two protective plates 1 can be connected via the two connectors 5. The design of the connectors 5 further improves the tightness of the connection between the two protective plates 1, preventing the protective plates 1 from falling off and effectively improving the stability of the device. The connectors 5 are provided with connection holes, and fastening screws are sequentially passed through the two connection holes and then threadedly connected to nuts, so that the two protective plates 1 can be connected via the fastening screws.

[0033] like Figure 1 and Figure 4 As shown, the cable lead-in protection tube also includes a base 6, which is located at the bottom of the protective plate 1. The tubular structure formed by the two protective plates 1 is plugged into the base 6, and a fixing nail 7 is fixedly connected to the bottom of the base 6. The base 6 can limit and fix the protective plate 1, and further lower the center of gravity of the protective plate 1, thereby improving the stability of the protective plate 1. At the same time, the fixing nail 7 at the bottom of the base 6 can facilitate the fixed installation of the base 6 to prevent the device from offsetting during subsequent work.

[0034] like Figure 1 and Figure 3As shown, a protective cover 8 is provided on the top of the protective plate 1, and a sealing rubber ring 9 is fixedly connected to the inside of the protective cover 8. The sealing rubber ring 9 is made of a water-absorbing and expanding rubber ring. The design of the protective cover 8 can cover the enclosed protective plate 1 to prevent insects, rodents and other creatures from entering the device and damaging the cable lead-in line. At the same time, the design of the sealing rubber ring 9 that absorbs water and expands can reduce the infiltration of rainwater in rainy weather, thereby further ensuring the safety of the cable lead-in line.

[0035] like Figure 4 As shown, the bottom of the protective cover 8 is fixedly connected with a limit rod 10, and the limit rod 10 is used to be inserted into the gap between the protective inner layer and the protective outer layer. The outer wall of the protective cover 8 is fixedly connected with an indicator block 11. The limit rod 10 can provide effective limitation for the protective cover 8 to prevent the protective cover 8 from moving at will. At the same time, the indicator block 11 can facilitate the staff to quickly realize the connection work between the protective cover 8 and the protective plate 1, thereby improving work efficiency.

[0036] The present invention relates to a device for protecting a cable lead-in wire. When in use, one end of the cable lead-in wire is passed through the base 6 and the protective cover 8. Then, the cable lead-in wire is placed between the two protective plates 1. Then, the protrusion 101 of one protective plate 1 is inserted into the slot 102 of the other protective plate 1, so that the two protective plates 1 are connected through the protrusion 101 and the slot 102. At this time, the arc rubber plate 4 is kept in contact with the cable lead-in wire. Then, the two protective plates 1 after encirclement are inserted into the base 6, and the protective cover 8 is put on the two protective plates 1 after encirclement, thereby completing the assembly of the device. Then, the base 6 is fixedly installed on the ground to provide protection for the cable lead-in wire. When the protective plate 1 is hit, the spring 3 connected to the hit protective plate 1 is compressed after being squeezed by the protective plate 1. Then, the spring 3 is restored by its own resilience and the force applied to it is dissipated during the restoration process, thereby providing a buffer for the cable lead-in wire inside the device to prevent the cable lead-in wire from being damaged by impact. The work is now completed.

[0037] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
