Description

Technical Field

[0001] The utility model relates to the technical field of cable armoring, in particular to a novel cable armoring structure of anti-corrosion galvanized steel strips. Background Art

[0002] In the field of power transmission and communication, cables are an indispensable infrastructure, widely used to connect different devices, transmit power and information. In order to ensure the stability and safety of cables in various environments and conditions of use, continuous technological innovation is essential. Because cables are mostly used outdoors, they are inevitably exposed to harsh environments for a long time, such as rainy and snowy weather. Therefore, in order to prevent rain and humid air from entering the interior of the cable, the cable needs to have strong protection capabilities; because the cable is used outdoors, it may be deformed by external pressure, so an additional protective structure is needed to offset the pressure of the deformation of the armor on the conductor.

[0003] Therefore, it is very necessary to invent a new type of cable armor structure with anti-corrosion galvanized steel strip. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a new type of cable armor structure of anti-corrosion galvanized steel strip, so as to solve the problems that the existing cable armor structure still has the problem that the armor is easily damaged to the conductor after being compressed and deformed, the armor has poor protection ability, and cannot be used for a long time in harsh environment. A new type of cable armor structure of anti-corrosion galvanized steel strip includes a cable cushion layer, an armor support layer, a protective armor and an armor protective sleeve, the cable cushion layer is coated on the outside of the cable filler, and the armor support layer is tightly attached to the outer surface of the cable cushion layer, and the protective armor is covered on the armor support layer; the armor protective sleeve is wrapped on the outside of the protective armor.

[0005] The protective armor includes a protective armor steel belt, a matching armor steel belt, an outer buffer layer and an inner anti-deformation layer, and the matching armor steel belt is fixedly installed on the bottom surface of the protective armor steel belt, and the outer buffer layer is adhesively fixedly installed on the surface of the protective armor steel belt; the inner anti-deformation layer is adhesively fixedly installed on the surface of the matching armor steel belt.

[0006] The armor support layer adopts a layer of rubber pipe, and the armor support layer is tightly fitted to the outer surface of the cable cushion layer and is bonded and fixed by glue; the surface of the armor support layer is roughly polished, and a layer of metal mesh is arranged inside the armor support layer for structural support: the armor support layer provides additional structural support for the cable, increases the overall stiffness and strength of the cable, which is crucial for maintaining the shape and structure of the cable, especially when the protective armor is covered, so that the pressure will not be directly applied to the conductor inside the cable, causing the conductor to bend, thereby causing the loss of electricity during transmission.

[0007] The protective armor steel belt and the matching armor steel belt inside the protective armor are both made of galvanized steel metal belts, and the thickness of the protective armor steel belt is greater than that of the matching armor steel belt, and the width of the matching armor steel belt is consistent with that of the protective armor steel belt; the matching armor steel belt is offset to one side on the bottom surface of the protective armor steel belt, and a misalignment is formed between the protective armor steel belt and the matching armor steel belt; the outer buffer layer adopts a rubber pad that matches the protective armor steel belt, and the inner anti-deformation layer adopts a soft silicone pad that matches the matching armor steel belt, which has the following functions: ① Mechanical protection: The protective armor provides mechanical protection for the cable during transportation, installation and use. It can prevent the external environment from squeezing, bending, stretching and other mechanical damage to the cable, thereby protecting the conductor and insulator inside the cable from damage; ② Anti-corrosion: If the cable is used in harsh environmental conditions, such as humid, corrosive gas or chemical environments, the protective armor can provide corrosion protection. ③Fixation and fit: The fitting armored steel belt is located on the bottom surface of the protective armored steel belt. Its main function is to fit with the protective armored steel belt to ensure a firm connection between the two and prevent them from sliding or separating relative to each other during the use of the cable. It can also fill the gap formed after the protective armored steel belt is installed. ④Dislocation structure: One side of the fitting armored steel belt is offset to form a dislocation structure with the protective armored steel belt. This dislocation can increase the overall stability and mechanical strength of the protective armor and improve the durability of the cable. ⑤Prevent the armor from being impacted by the outside: The participation of the outer buffer layer can make the metal armor directly impacted, and the outer buffer layer can provide a certain degree of protection for the armor: ⑥Prevent internal cable damage. When the armor is deformed after receiving a large impact, the inner anti-deformation layer will change its properties, cooperate with the deformation of the armor, and prevent the deformation of the armor from affecting the internal cable.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] 1. The armor support layer of the utility model is provided for structural support: the armor support layer provides additional structural support for the cable, increases the overall rigidity and strength of the cable, which is essential for maintaining the shape and structure of the cable, especially when the protective armor is covered, so that the pressure will not be directly applied to the conductor inside the cable, causing the conductor to bend, thereby causing the loss of electricity during transmission.

[0010] 2. The setting of the protective armor of the utility model has the following functions: ① Mechanical protection: The protective armor provides mechanical protection for the cable during transportation, installation and use. It can prevent the external environment from squeezing, bending, stretching and other mechanical damage to the cable, thereby protecting the conductors and insulators inside the cable from damage; ② Anti-corrosion: If the cable is used in harsh environmental conditions, such as moisture, corrosive gases or chemicals, the protective armor can provide additional protection against corrosion, which helps to extend the service life of the cable and maintain its performance; ③ Fixation and fit: The fitting armor steel belt is located on the bottom surface of the protective armor steel belt. Its main function is to fit with the protective armor steel belt to ensure a firm bond between the two. ④ Dislocation structure: one side of the armored steel belt is offset to form a dislocation structure with the protective armored steel belt. This dislocation can increase the overall stability and mechanical strength of the protective armor and improve the durability of the cable; ⑤ Prevent the armor from being impacted by the outside: The participation of the outer buffer layer can make the metal armor directly receive the impact, and the outer buffer layer can provide a certain protection for the armor: ⑥ Prevent internal cable damage. When the armor is deformed after receiving a large impact, the inner anti-deformation layer will change its properties, cooperate with the deformation of the armor, and prevent the deformation of the armor from affecting the internal cable.
