Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to an anti-ultraviolet aging device for environmentally friendly PVC cables. Background Art

[0002] Environmentally friendly PVC cables are environmentally friendly wire and cable products, commonly used in power transmission and wiring systems. They use environmentally friendly polyvinyl chloride (PVC) as insulation material. PVC cables have good corrosion resistance and insulation, but they are also susceptible to oxidation and ultraviolet rays and are prone to aging, so they need to be protected with anti-ultraviolet aging devices.

[0003] The existing environmentally friendly PVC cable's anti-ultraviolet aging device is mostly a layer of protective cover, which is wrapped around the cable side wall and has a certain anti-ultraviolet effect. Although this protective cover can slow down the aging of PVC cables to a certain extent, due to its closed structure and the close fit with the cable, it will greatly limit the heat dissipation of the cable and affect the service life of the cable. Moreover, the flat protective cover is not convenient for bending the cable, and its use is relatively limited. In addition, in order to ensure the firmness of the protective cover, it is generally chosen to install the protective cover during cable processing, which makes subsequent disassembly and replacement inconvenient, and even impossible to achieve complete disassembly, and the flexibility is not strong. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides an anti-ultraviolet aging device for an environmentally friendly PVC cable, which has good air permeability and heat dissipation, is convenient for bending the cable to adjust the angle, and can be quickly disassembled and replaced.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: an anti-ultraviolet aging device for environmentally friendly PVC cables, comprising a protective cover, a protective net and a splint, the protective cover and the protective net are rotatably connected, the protective cover and the protective net can form a cylindrical shape that matches the cable, the protective cover and the protective net are connected and fixed by a fixed structure, the splints are grouped in pairs, and multiple groups of the splints are fixed on the inner side of the protective cover and the protective net, the splint close to the protective cover is connected to the protective cover by a support block, a number of grooves are provided on the outer wall of the protective cover, and an anti-ultraviolet coating is provided on the outer wall of the protective cover and the protective net.

[0006] Furthermore, the fixing structure is provided in plurality, and the fixing structure includes a fixing block and a bolt. The fixing blocks are provided in two and are respectively fixed at the edges of the protective cover and the protective net, and the two fixing blocks are fixed by bolt connection.

[0007] Furthermore, the clamping plate is an arc-shaped plate, and a rubber pad is connected to the inner side of the clamping plate.

[0008] Furthermore, the clamping plate and the supporting block are both made of heat-insulating materials.

[0009] Furthermore, the protective cover is made of polyurethane, and the anti-ultraviolet coating is acrylic paint.

[0010] Compared with the prior art, the utility model has the following advantages: the setting of the protective net facilitates the heat dissipation of the cable, and the support block and the clamping plate can ensure that there is a gap between the cable and the protective shell and the protective cover, which is also convenient for ventilation and heat dissipation; the design of the groove facilitates the bending of the protective shell within a certain range, thereby realizing the bending of the cable, and avoiding excessive bending of the cable; the utility model is flexible and safe; the protective shell and the protective cover are rotatably connected and fixed by bolts, which is convenient and practical for direct and quick installation on the cable and replacement.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Combined with Figure 1 To Attachment Figure 4 An environmentally friendly PVC cable anti-ultraviolet aging device comprises a protective cover 1, a protective net 2 and a clamping plate 3. The protective cover 1 and the protective net 2 are rotatably connected. The protective cover 1 and the protective net 2 can form a cylindrical shape that matches the cable. The protective cover 1 and the protective net 2 are connected and fixed by a fixed structure. The fixed structure is provided with multiple fixed structures, including a fixed block 6 and a bolt 7. The fixed block 6 is provided with two and is respectively fixed at the edges of the protective cover 1 and the protective net 2. The two fixed blocks 6 are connected and fixed by bolts 7. Multiple groups of fixed structures can ensure the connection stability of the protective cover 1 and the protective net 2. Using bolts 7 to fix the fixed block 6 is simple and convenient to operate and firmly fixed.

[0018] Combined with Figure 1 , Attachment Figure 3 , Attachment Figure 4The clamping plates 3 are arranged in groups of two, and multiple groups of the clamping plates 3 are fixedly arranged on the inner side of the protective cover 1 and the protective net 2. The clamping plates 3 are arc-shaped plates, and rubber pads 8 are connected to the inner side of the clamping plates 3. The rubber pads 8 can prevent the clamping plates 3 from damaging the cables, which is safe and reliable.

[0019] Combined with Figure 3 The clamping plate 3 close to the protective cover 1 is connected to the protective cover 1 through a supporting block 4. The clamping plate 3 and the supporting block 4 are both made of heat-insulating materials, which can prevent the heat on the protective cover 1 and the protective net 2 from being transferred to the cable, which is beneficial to improving the service life of the cable.

[0020] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 4 The outer wall of the protective cover 1 is provided with a plurality of grooves, and the outer walls of the protective cover 1 and the protective net 2 are provided with an anti-ultraviolet coating 5. The protective cover 1 is made of polyurethane, and the anti-ultraviolet coating 5 is an acrylic paint, which has good anti-ultraviolet performance and is conducive to ensuring the service life of the device.

[0021] Specific implementation methods of the utility model are as follows: open the protective cover 1 and the protective net 2, place the protective cover 1 and the protective net 2 on the near-light side and the back-light side of the cable respectively, and then rotate the two to form a cylindrical shape and wrap around the cable, and use bolts 7 to fix the adjacent fixing blocks 6 to achieve the fixation of the protective cover 1 and the protective net 2. At this time, the splint 3 is in close contact with the cable to fix the cable, and the cable can dissipate heat through the protective net 2 and the gap between itself and the protective cover 1 and the protective net 2. During the use of the cable, the protective net 2, the protective cover 1 and the anti-ultraviolet coating 5 can play multiple protective roles on the cable and have a good anti-aging effect. When the cable is bent, the groove will stretch or shrink to match its bending.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
