Description

Technical Field

[0001] This utility model relates to the field of power cable transmission protection, and in particular to a cable reel protection structure. Background Technology

[0002] Traditional cable transportation methods (such as direct loading into steel-side boxes) lack effective cushioning structures. Bumps and vibrations during transportation can easily cause scratches on the surface of cold shrink terminals or damage to their internal structure. For example, rigid collisions during forklift transportation may damage the insulation or semi-conductive layers of cold shrink terminals, increasing the risk of leakage. Cold shrink terminals are sensitive to humidity and contaminants, but some packaging solutions do not use sealants or waterproof materials, which may allow moisture to seep in and affect the insulation performance of the terminals. Cold shrink terminals have a short storage period (usually six months to two years). If the transportation period is too long or the storage environment is improper (such as high temperature or ultraviolet exposure), materials such as silicone rubber may age prematurely, leading to elastic failure or a decrease in insulation performance.

[0003] Existing technologies include some cable reel protection structures that use cushioning materials to cover and protect the inside of the reel body and side plates to protect the cable. However, for long-distance cable transportation, factors such as shaking during transportation need to be considered, and specific areas of the cable (such as cable terminals) require targeted protection. While the above solutions can provide cable protection to a certain extent, there is still a problem of inadequate protection of the internal cable structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable reel protection structure that provides protection for both the inside and outside of the cable terminal. The multi-layer protection can effectively protect the cable and ensure the reliability of long-distance cable transportation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An embodiment of this utility model provides a cable reel protection structure, including a cable and a cable reel, wherein the cable is wound around the cable reel to form a winding layer, and a first wrapping layer is provided on the outside of the winding layer;

[0007] The cable has a cable terminal, and the cable terminal is provided with a protective structure; the protective structure includes a second wrapping layer and a third wrapping layer, the second wrapping layer is provided on the outside of each phase of the cable terminal, and the third wrapping layer is provided on the outside of the second wrapping layer of each phase.

[0008] As a further implementation, a padding layer is provided between the winding layer and the cable reel, and the padding layer supports the inner end of the cable.

[0009] As a further implementation, the underlayment includes multiple pad blocks.

[0010] As a further implementation, the first wrapping layer includes a first foam layer, a first stretch film, and a first fixing layer arranged sequentially from the inside to the outside.

[0011] As a further implementation, the outer side of the first fixing layer is secured with cable ties.

[0012] As a further implementation, the second wrapping layer includes a second foam layer and a second stretch membrane arranged sequentially from the inside to the outside.

[0013] As a further implementation, the third wrapping layer includes a third foam layer, a third stretch membrane, and a third fixing layer arranged sequentially from the inside to the outside.

[0014] As a further implementation, multiple layers of fourth stretch membrane are also provided on the outside of the third fixing layer.

[0015] As a further implementation, the outer end of the cable located at the cable terminal is fixed to the cable reel by a pull rope.

[0016] As a further implementation, the cable termination does not protrude beyond the periphery of the cable reel.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The cable of this utility model is wound around the cable reel, and each phase core of the cable terminal is provided with a wrapping layer, and a wrapping layer is provided on the outside of each phase core. At the same time, a wrapping layer is also provided on the outside of the cable winding layer wound around the cable reel, forming a multi-level protection structure to ensure the stability of the cable during transportation and achieve effective protection measures.

[0019] (2) Each wrapping layer of this utility model includes a foam layer and a stretch film. By wrapping and fixing the cable end with the foam layer and stretch film, it can effectively prevent the cable from shifting or colliding due to vibration or external force during transportation, thereby protecting the cable end from damage. Furthermore, wrapping and covering the entire cable reel with foam layer and stretch film can further enhance the overall stability of the cable and reduce shaking and friction during transportation; at the same time, a fixing layer is also set on the outside of the cable terminal and the outside of the wrapping layer to further secure the cable to the cable reel.

[0020] (3) The cable inner end of this utility model is provided with a pad between the cable reel and the cable reel, so that the inner end of the cable can still be easily taken out for a certain length after the cable is loaded onto the reel, so as to meet the installation of the cable terminal after the cable is cut.

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] In the description of this utility model, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Example 1:

[0029] This embodiment provides a cable reel protection structure, including a cable and a cable reel 1, as shown below. Figure 1 and Figure 2 As shown, the cable is wound in multiple layers on the outside of the cable reel 1 to form a winding layer; in order to ensure the safe and long-distance transportation of the cable, this embodiment sets a protective structure for each phase and multiple phases of the cable terminal, and sets a protective structure after the cable is wound in the cable reel 1 to form a multi-level protection.

[0030] For ease of description, the outer wrapping layer of the cable winding is referred to as the first wrapping layer; since the cable is composed of multi-phase conductors 5, the outer wrapping layer of each phase conductor 5 at the cable terminal is referred to as the second wrapping layer, and the common wrapping layer outside the second wrapping layers of all phase conductors 5 is referred to as the third wrapping layer. In this embodiment, the cable is composed of three-phase ground wires and one-phase main wire; therefore, after the second wrapping layers are respectively set outside the ground wires and the main wire, the third wrapping layer is set outside the second wrapping layers.

[0031] Each sheathing layer is installed after the cable withstand voltage test. Specifically, for the second sheathing layer outside each phase conductor 5, such as... Figure 3As shown, the second wrapping layer includes a second foam layer 6 and a second stretch film 7. The second foam layer 6 wraps around the outside of the main wire and ground wire at the cable terminal, and then the second stretch film 7 fixes the second foam layer 6 to the corresponding wire core 5. Next, a third foam layer 8 is jointly provided on the outside of the 3+1 phases, and the second stretch film 7 is placed on the outside of the third foam layer 8 to ensure a complete seal from the cable branch to the umbel end and T-joint end. Then, a third fixing layer 10 and a fourth stretch film (not shown in the figure) are placed on the outside of the second stretch film 7, and the fourth stretch film fixes the third fixing layer 10, further strengthening the fixation. The fourth stretch film can be wrapped in multiple layers, such as three layers.

[0032] The end of the cable terminal is the cable outer end 4. After the cable is wrapped, the cable outer end 4 is fixed to the cable reel 1 by a pull rope to ensure the initial fixation of the wrapping layer. Then, a first wrapping layer (not shown in the figure) is set on the outside of the wrapping layer. The first wrapping layer includes a first foam layer, a first stretch film, and a first fixing layer arranged sequentially from the inside to the outside. The first foam layer is wrapped around the outside of the wrapping layer, and then the first stretch film is wrapped to completely cover all cable areas to ensure that moisture does not enter the end. The first fixing layer is wrapped around once, and finally, it is tied tightly with a cable tie.

[0033] In this embodiment, each foam layer is made of white foam plastic; each fixing layer is made of woven bags, which not only strengthens the protection but also has a low cost.

[0034] Considering that the cable terminal and protective structure will be larger than the original cable outer diameter after installation, it is necessary to select a suitable cable reel 1 size to ensure that the cable terminal does not protrude from the perimeter edge of the cable reel 1 after installation.

[0035] In this embodiment, a padding layer is also provided between the winding layer and the cable reel 1, such as... Figure 1 and Figure 2 As shown, the padding layer is located inside the cable connector to support the cable connector and maintain a certain distance between it and the cable reel 1. This allows the inner end of the cable to be easily removed after being reeled, facilitating the installation of the cable termination after disconnection. The padding layer consists of multiple pad blocks 3, which are spaced apart along the circumference of the cable reel 1.

[0036] This embodiment uses a foam layer and stretch film to wrap and secure the cable ends, effectively preventing displacement or collisions caused by vibration or external forces during transportation, thus protecting the cable ends from damage. Furthermore, covering the entire cable reel with foam and stretch film further enhances the overall stability of the cable, reducing shaking and friction during transport. The foam layer and stretch film have excellent sealing properties, effectively preventing moisture from entering the cable ends and avoiding performance degradation of the cable insulation due to moisture. This embodiment, through multi-layer wrapping and sealing, ensures that the cable maintains its original electrical performance during transportation, reducing performance degradation caused by environmental factors.

[0037] Furthermore, by winding the cable around the cable reel 1 and setting up a protective structure, the cable does not extend beyond the circumference of the cable reel 1, making it easier to handle and stack the cable during transportation, which can improve transportation efficiency and reduce space occupation.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
