[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A protection device for high-voltage cable conversion and renovation includes multiple groups of vertical wall components. Each group of vertical wall components is composed of multiple sequentially connected vertical wall modules. The vertical wall components extend along the extension direction of the high-voltage cable, and the vertical wall modules are all installed on fixing members.

[0007] Among them, a connection structure for fixing the vertical wall module is provided on the fixing member, and there is a spacing between adjacent two connection structures for forming an accommodation space for accommodating the high-voltage cable between adjacent two vertical wall modules.

[0008] In one embodiment, both the vertical wall module and the fixing member are made of rubber material.

[0009] In one embodiment, the fixing member includes multiple second bases and first bases at the head and tail ends of the high-voltage cable.

One end of the vertical wall module is a clamping groove with an opening, and the other end is a clamping cylinder that matches it, so that one of the vertical wall modules can rotate around the adjacent vertical wall module.

[0011] In one embodiment, the connection structure on the first base includes a plurality of connection bumps whose quantity is the same as that of the connection grooves of the vertical wall modules. The connection structure on the second base is a single connection bump, and the connection bump and the connection groove match each other.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The present invention will be further described below in conjunction with the drawings.

[0033] Currently, during the transformation of high-voltage cable types, in order to prevent accidental damage to adjacent live-running high-voltage cables when cutting old high-voltage cables, wooden boards are usually nailed for protection, which not only wastes a large number of professional carpenters but also consumes a lot of time. The one-time use of wood causes a large amount of waste and environmental pollution. Moreover, the wooden boards are fixed by nails, and during the installation process, due to the narrow space, the live-running high-voltage cables may be damaged;

[0034] The present invention provides a protection device for the transformation of a high-voltage cable 100. As Figure 1 shown, it includes multiple groups of vertical wall components. Each group of vertical wall components is composed of multiple sequentially connected vertical wall modules 3. 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 members;

[0035] Among them, a connection structure for fixing the vertical wall module 3 is provided on the fixing member, and there is a spacing between adjacent two connection structures for forming an accommodation space for accommodating the high-voltage cable 100 between adjacent two vertical wall modules 3;

[0036] It should be noted that in this embodiment, multiple sequentially connected vertical wall modules 3 form a vertical wall component extending along the high-voltage cable 100. The high-voltage cable 100 is arranged in the accommodation space between adjacent two vertical wall components, effectively protecting the high-voltage cable 100 during the transformation process. That is, by adopting an assembled method, it meets 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 protection structure form is convenient for repeated use and saves the cost of transformation;

[0037] Specifically, in this embodiment, as Figures 1 to 4 shown, both the vertical wall module 3 and the fixing member are made of rubber materials. The fixing member includes multiple second bases 2 and first bases 1 located at the head and tail ends of the high-voltage cable 100. The second bases 2 are located between the first bases 1, and the width of the first base 1 is greater than that of the second base 2 for the high-voltage cable 100 to bend and extend. The bottom of the vertical wall module 3 has multiple connection grooves 305 that cooperate with the connection structure. One end of the vertical wall module 3 is a clamping groove with an opening, and the other end is a clamping cylinder 301 that matches it for one vertical wall module 3 to rotate around the adjacent vertical wall module 3;

[0038] It should be noted that the vertical wall module 3 and the fixing member made of rubber materials are used to protect the high-voltage cable 100. The connection grooves 305 at the bottom of the rubber material vertical wall module 3 are convenient for directly pressing and installing on the connection structure on the rubber material fixing member. When disassembling, just pull it out and use it repeatedly. No other sharp tools are needed, avoiding damage to the high-voltage cable 100 during the transformation operation. At the same time, the adjacent vertical wall modules 3 can adjust the angle, which is convenient for adapting to various bending serpentine extension paths of the high-voltage cable 100. While ensuring the protection in place, compared with the traditional technical solution, it will not affect the work efficiency due to the complex serpentine path of the high-voltage cable 100;

[0039] Further, the connection structure on the first base 1 includes a plurality of connection bumps 5 whose quantity is the same as that of the connection grooves 305 of the vertical wall module 3. The connection structure on the second base 2 is a single connection bump 5, and the connection bump 5 and the connection groove 305 match each other;

[0040] It should be noted that the first base 1 is arranged at the head and tail ends of the high-voltage cable 100 and serves as the main support node. The vertical wall module 3 thereon is completely installed on the first base 1, while the second base 2 serves as the adjustment support node located between the first bases 1, and only one connection bump 5 is required to connect the vertical wall module 3;

[0041] Specifically, in this embodiment, there are 4 groups of connection structures above the first base 1. Each group of connection structures has 6 connection bumps 5, which are symmetrically arranged on both sides, with 3 connection bumps 5 on each side. The bottom of the vertical wall module 3 has 6 connection grooves 305, and the 6 connection grooves 305 completely correspond to the 6 connection bumps 5 in a group of connection structures on the first base 1, so that the vertical wall module 3 can be completely installed on the first base 1. There are also 4 groups of connection structures correspondingly arranged above the second base 2. The distance between adjacent two groups of connection structures is the same as that on the first base 1, but each group of connection structures on the second base 2 only has one connection bump 5, and the connection groove 305 at one end of the vertical wall module 3 matches it, so that each vertical wall module 3 can serve as an angle adjustment node to easily cope with the complex serpentine extension path of the high-voltage cable 100, and at the same time serve as an auxiliary support node to connect the entire protection device;

[0042] In one embodiment, as Figure 2 and Figure 3 shown, the surface of the vertical wall module 3 also has a plurality of bump structures 303 corresponding to the positions of the connection grooves 305 at its bottom. The bump structures 303 on the surface of the vertical wall module 3 correspond to the connection grooves 305 at its bottom, which can realize repeated accumulation on the basis of the vertical wall module 3 to adapt to high-voltage cables 100 of different sizes, and can also solve the situation where there are multiple groups of high-voltage cables 100 at the same position;

[0043] In one embodiment, as Figure 4 shown, the end of the vertical wall module 3 is connected to the clamping 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 clamping groove is 30°.

[0044] In one embodiment, as Figure 1 shown, there are also a plurality of cover plates 4 located above the high-voltage cable 100. The cover plates 4, the vertical wall modules 3 and the connection structure form a closed structure around 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, the high-voltage cable 100 is comprehensively protected by arranging continuous cover plates 4 on the vertical wall modules 3;

[0045] In one embodiment, the present invention further provides a protection method for the transformation of high-voltage cables, including the following steps:

[0046] Step S1: Set up first bases at both the head and tail ends of the high-voltage cable, and install vertical wall modules thereon, so that all the connection grooves of the vertical wall modules are installed on the connection bumps of the first bases;

[0047] Step S2: Lay second bases one by one along the serpentine extension direction of the high-voltage cable, and install vertical wall modules thereon, so that the clamping grooves at one end of the vertical wall modules are set on the connection bumps of the second bases;

[0048] Step S3: Connect adjacent vertical wall modules in the same group of vertical wall components, and adjust the included angle between adjacent two vertical wall modules along the serpentine extension direction of the high-voltage cable, so that the distances between the high-voltage cable and adjacent two groups of vertical wall components are the same;

[0049] Step S4: Set up a cover plate above the high-voltage cable along the serpentine extension direction of the high-voltage cable, and use the cover plate, vertical wall modules and connection structures to form a sealed structure around the high-voltage cable to protect the high-voltage cable;

[0050] Among them, in step S4, both sides of the cover plate are installed on the bump structures of adjacent two groups of vertical wall components;

[0051] It should be noted that compared with the traditional method of nailing wooden boards for protection, this method not only saves a large number of professional carpenters, but also saves a lot of time. There are no problems of high cost and environmental pollution caused by the one-time use of a large amount of wood and its difficulty in recycling. During the transformation process, there are no sharp tool accessories such as nails, etc., that is, the risk of damaging the live high-voltage cable is greatly reduced;
