[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Currently, during the high-voltage cable replacement and renovation process, in order to prevent accidental damage to adjacent energized high-voltage cables when cutting old high-voltage cables, wooden boards are usually nailed together for protection. This not only wastes a lot of professional carpenters, but also consumes a lot of time. A large amount of wood is wasted when used at once, causing environmental pollution. In addition, the wooden boards are fixed by nails, and during the installation process, due to the confined space, the energized high-voltage cables may be damaged.

[0029] This utility model provides a protective device for high-voltage cable replacement and retrofitting, such as Figure 1 As shown, it includes multiple sets of vertical wall components, each set of vertical wall components consists of multiple vertical wall modules 3 connected in sequence. The vertical wall components extend along the extension direction of the high-voltage cable 100, and the vertical wall modules 3 are all installed on the fixing parts.

[0030] The fastener is provided with a connection structure for fixing the vertical wall module 3. There is a gap between two adjacent connection structures so that a space for accommodating the high-voltage cable 100 can be formed between two adjacent vertical wall modules 3.

[0031] It should be noted that in this embodiment, multiple sequentially connected vertical wall modules 3 form a vertical wall assembly extending along the high-voltage cable 100. The high-voltage cable 100 is set in the accommodating space between two adjacent vertical wall assemblies, effectively protecting the high-voltage cable 100 during the transformation and modification process. That is, the assembly method is adopted to meet the serpentine extension scenario of the high-voltage cable 100, greatly improving its transformation efficiency while effectively protecting the high-voltage cable 100. The assembled protective structure is convenient for reuse and saves the cost of transformation and modification.

[0032] Specifically, in this embodiment, such as Figures 1 to 4 As shown, the vertical wall module 3 and the fixing components are all made of rubber material. The fixing components include multiple second bases 2 and a first base 1 located at the beginning and end of the high voltage cable 100. The second bases 2 are located between the first bases 1. The width of the first base 1 is greater than that of the second base 2 so that the high voltage cable 100 can be bent and extended. The bottom of each vertical wall module 3 has multiple connecting grooves 305 that cooperate with the connecting structure. One end of the vertical wall module 3 is a locking groove with an opening, and the other end is a locking cylinder 301 that matches it, so that one of the vertical wall modules 3 can rotate around the adjacent vertical wall module 3.

[0033] It should be noted that the high-voltage cable 100 is protected by the vertical wall module 3 made of rubber material and the fasteners. The connecting groove 305 at the bottom of the rubber vertical wall module 3 allows for direct pressing onto the connection structure on the fasteners. It can be pulled out for disassembly and reused repeatedly without the need for other sharp tools. This avoids damage to the high-voltage cable 100 during the transformation and modification process. At the same time, the angle of the adjacent vertical wall module 3 can be adjusted to adapt to the various curved and serpentine extension paths of the high-voltage cable 100. This ensures adequate protection and, compared to traditional technical solutions, does not affect work efficiency due to the complex serpentine path of the high-voltage cable 100.

[0034] Furthermore, the connecting structure on the first base 1 includes multiple connecting protrusions 5, the same number as the connecting grooves 305 of the vertical wall module 3, and the connecting structure on the second base 2 is a single connecting protrusion 5, with the connecting protrusion 5 matching the connecting groove 305.

[0035] It should be noted that the first base 1 is set at both ends of the high-voltage cable 100 as the main support node, and the vertical wall module 3 on it is completely installed on the first base 1. The second base 2, as the adjustment support node located between the first bases 1, only needs one connecting protrusion 5 to connect the vertical wall module 3.

[0036] Specifically, in this embodiment, four sets of connecting structures are provided on the top of the first base 1. Each set of connecting structures has six connecting protrusions 5, which are symmetrically arranged on both sides, with three connecting protrusions 5 on each side. The bottom of the vertical wall module 3 has six connecting grooves 305. The six connecting grooves 305 correspond completely to the six connecting protrusions 5 in one set of connecting structures of the first base 1, so that the vertical wall module 3 can be completely installed on the first base 1. The top of the second base 2 is also provided with four sets of connecting structures. The spacing between two adjacent sets of connecting structures is the same as that on the first base 1, but each set of connecting structures on the second base 2 has only one connecting protrusion 5. The connecting groove 305 at one end of the vertical wall module 3 matches it, so that each vertical wall module 3 can be used as an angle adjustment node to easily cope with the complex serpentine extension path of the high-voltage cable 100, and also as an auxiliary support node to connect the entire protective device.

[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the surface of the vertical wall module 3 also has multiple protrusion structures 303 corresponding to the connection grooves 305 at its bottom. The protrusion structures 303 on the surface of the vertical wall module 3 correspond to the connection grooves 305 at its bottom, which means that it can be repeatedly added on the basis of the vertical wall module 3 to accommodate high-voltage cables 100 of different sizes, and can also solve the problem of multiple sets of high-voltage cables 100 at the same location.

[0038] In one embodiment, such as Figure 4 As shown, the end of the vertical wall module 3 is connected to the positioning cylinder 301 through the connecting section 304, and the included angle between the left and right ends of the connecting section 304 and the opening of the positioning groove is 30°.

[0039] In one embodiment, such as Figure 1 As shown, it also includes multiple cover plates 4 located above the high-voltage cable 100. The cover plates 4, together with the vertical wall module 3 and the connecting structure, form a closed structure surrounding the high-voltage cable 100. The two sides of the cover plates 4 are respectively connected to two adjacent vertical wall modules 3. That is, by setting continuous cover plates 4 on the vertical wall module 3, the high-voltage cable 100 is protected in all directions.

[0040] Specifically, the two sides of the cover plate 4 are respectively installed on the protrusion structure 303 of the two adjacent sets of vertical wall components;

[0041] It should be noted that, compared with traditional wooden board nailing protective devices, the protective device provided by this utility model utilizes the mutually cooperating vertical wall module 3 and fasteners, which can be quickly assembled and disassembled and adjusted at will along the extension direction of the high-voltage cable 100. This not only saves a lot of professional carpenters, but also saves a lot of time. It does not have the cost problem of using a large amount of wood at one time and being difficult to recycle, nor does it have the problem of environmental pollution. During the modification process, there are no sharp tools or accessories, such as nails, which greatly reduces the risk of damage to the energized high-voltage cable.
