Technical Field

[0001] The present invention relates to the technical field of power cables, in particular to a tensile-resistant, heat-insulating, double-layer armored, fire-resistant power cable. Background Art

[0002] Power cables are an indispensable and important part of the power system. Their main function is to transmit electrical energy from power plants to various electricity users to ensure the normal operation of the power system.

[0003] Most current power cables have poor tensile strength. When subjected to external mechanical shock, the cores are prone to compression and wear. This provides insufficient protection for the cable's internal structure, making the cable easily damaged. While some damage often cannot be directly seen from the outside, it can greatly reduce the cable's service life and easily create safety hazards during use. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a tensile-resistant, heat-insulating, double-layer armored fire-resistant power cable, which has the advantage of being able to separate and protect the cable cores, thereby improving their service life. It solves the problem in the existing technology that when the cable encounters external mechanical impact, the cores are prone to extrusion and wear, and the protection ability of the internal structure of the cable is insufficient, making the cable easily damaged.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A tensile-resistant, heat-insulating, double-layer armored, fire-resistant power cable, comprising a plurality of core bodies as the main body of the device, a protective mechanism for protecting the core bodies being arranged on the outside of the plurality of core bodies, the protective mechanism comprising an insulating layer, a separation mechanism for avoiding extrusion between the plurality of core bodies being arranged between the plurality of core bodies, an armor mechanism for improving the overall tensile strength of the cable being arranged on the outside of the protective mechanism, the separation mechanism comprising a fixing rod, a plurality of circular rings being mounted on the fixing rod, a plurality of notches being provided on the plurality of circular rings, a connecting plate being fixedly connected to the plurality of circular rings, a plurality of arc-shaped airbag blocks and a plurality of arc-shaped frames being mounted on both sides of the plurality of connecting plates, a plurality of diamond-shaped holes being provided on the plurality of arc-shaped frames, and a filling tape being filled in the insulating layer.

[0006] Furthermore, a shielding layer is installed on the outer side of the insulating layer, and a protective layer is installed on the outer side of the shielding layer.

[0007] Furthermore, the thickness of the insulating layer is 1.5 mm and is made of PVC. The thickness of the shielding layer is 1 mm and is made of copper wire. It is woven and covered on the outside of the insulating layer to form a tight metal mesh. The thickness of the protective layer is 1.5 mm and is made of rubber. It is sleeved on the outside of the shielding layer.

[0008] Furthermore, the armoring mechanism includes a first armoring layer and a second armoring layer, a plurality of card blocks are installed on the first armoring layer, and a plurality of card slots that fit with the plurality of card blocks are opened on the inner side of the second armoring layer.

[0009] Furthermore, the thickness of the first armor layer is 2 mm, it is made of steel wire, and is wound around the outside of the protective layer; the thickness of the second armor layer is 2 mm, it is made of aluminum tape, and is wound around the outside of the first armor layer.

[0010] Furthermore, the fixing rod is located at a central position, and the plurality of arc-shaped airbag blocks and the plurality of arc-shaped frames are staggeredly distributed.

[0011] Furthermore, the interior of the plurality of arc-shaped airbag blocks is filled with polyurethane material, the fabric thereof is made of nylon, and the material of the plurality of arc-shaped frames is aluminum.

[0012] Furthermore, the filling belt is made of polyester, and the plurality of connecting plates are distributed in a circular array around the fixing rod.

[0013] By means of the above technical solution, the present invention provides a tensile-resistant, heat-insulated, double-layer armored, fire-resistant power cable, which has at least the following beneficial effects: 1. This tensile-type heat-insulating double-layer armored fire-resistant power cable is equipped with a separation mechanism so that the device can separate and protect multiple cores. The fixing rod makes it easy to install multiple rings and easily adjust the positions of multiple connecting plates, thereby separating multiple core bodies. The core bodies are buffered and protected by multiple arc-shaped airbag blocks. The diamond-shaped holes on the multiple arc frames make the braided texture more stable and more elastic in structure, thereby further buffering the core bodies, thereby avoiding extrusion damage between the core bodies and improving the service life of the device.

[0014] 2. This tensile-type heat-insulating double-layer armored fire-proof power cable is equipped with a protection mechanism so that the device can protect the internal wire core body. The flame retardant effect of the cable is improved by the PVC insulation layer. A tight metal mesh is formed by the copper wire shielding layer. The higher the braiding density, the better the shielding effect. It also has good flexibility. The rubber protective layer makes the cable highly elastic and flexible, making the cable suitable for frequent movement.

[0015] 3. This tensile-type, heat-insulating, double-layer armored fire-resistant power cable effectively improves the tensile strength of the device by setting an armoring mechanism. The first layer of steel wire armor can effectively prevent the cable from being stretched or twisted during movement, ensuring the stability of the cable's internal structure. The second layer of aluminum tape armor makes the overall armor layer of the device lighter, while enhancing the cable's compressive and wear resistance. During long-term use, it can effectively reduce friction and wear between the cable and the surrounding environment, reducing the risk of damage due to external force.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Most power cables in the prior art have poor tensile strength. When subjected to external mechanical impact, the cores are easily squeezed and worn, and the protection of the internal structure of the cable is insufficient, making the cable easily damaged. However, this will greatly reduce the service life of the cable and easily cause safety hazards during use. The following describes a tensile-resistant, heat-insulating, double-layer armored, fire-resistant power cable provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0020] Example 1: In order to avoid the extrusion and wear between the cores when the cable encounters external mechanical impact, and effectively improve the protection ability of the internal structure of the cable, combined with Figure 1-Figure 5 As shown, a tensile-resistant, heat-insulating, double-layer armored, fire-resistant power cable is proposed. A plurality of core bodies 1 are provided as the main body of the device. A protective mechanism 3 is provided on the outside of the plurality of core bodies 1 to protect the plurality of core bodies 1. A separation mechanism 2 is provided between the plurality of core bodies 1 to avoid squeezing between the plurality of core bodies 1. An armor mechanism 4 is provided on the outside of the protection mechanism 3 to improve the overall tensile strength of the cable.

[0021] In order to avoid squeezing and damaging the multiple core bodies 1, a separation mechanism 2 is proposed. A fixing rod 201 is provided. A plurality of rings 202 are installed on the fixing rod 201. A plurality of rings 202 are provided with notches 203. A plurality of rings 202 are fixedly connected to a connecting plate 204. A plurality of arc-shaped airbag blocks 205 and a plurality of arc frames 206 are respectively installed on both sides of the plurality of connecting plates 204. A plurality of arc frames 206 are provided with a plurality of diamond-shaped holes 207. The insulating layer 301 is filled with a filling tape 208. By sequentially installing the plurality of rings 202 to the fixing rod 201, On the top, the multiple rings 202 can be easily disassembled and assembled under the action of the notch 203, and the multiple arc-shaped airbag blocks 205 and the multiple arc-shaped frames 206 are fixed by multiple connecting plates 204. The multiple arc-shaped frames 206 have the characteristics of lightness and high load-bearing capacity through multiple diamond-shaped holes 207. The weaving texture thereof is more stable in structure and will not be easily deformed. The multiple arc-shaped airbag blocks 205, the multiple arc-shaped frames 206 and the filling belt 208 can effectively buffer the multiple core bodies 1, thereby avoiding extrusion damage between the core bodies 1 and improving the service life of the device.

[0022] Among them, the fixing rod 201 is located in the center position, so that the multiple rings 202 drive the multiple connecting plates 204 to be distributed in a circular array, and the multiple arc-shaped airbag blocks 205 and the multiple arc-shaped frames 206 are staggered. The interior of the multiple arc-shaped airbag blocks 205 is filled with polyurethane material, which has good elasticity and wear resistance. It can quickly expand and buffer when squeezed, thereby protecting the core body 1 and having certain fire resistance to prevent internal fire. The material of the multiple arc frames 206 is aluminum, which makes it lighter as a whole. At the same time, it can effectively buffer the core body 1 with the diamond holes 207. The filling belt 208 is made of polyester material, which has high strength and wear resistance, can withstand large tension and friction, and has good insulation and flame retardant properties, which improves the safety performance of the cable and can meet the use requirements of the cable in different environments. Example 2: In order to protect the internal core body 1 from damage by the external environment, Figure 1 and Figure 5 As shown, a protection mechanism 3 is proposed, by setting an insulating layer 301, a shielding layer 302 is installed on the outside of the insulating layer 301, and a protective layer 303 is installed on the outside of the shielding layer 302. The thickness of the insulating layer 301 is 1.5 mm, and it is made of PVC. PVC is a thermoplastic resin that improves the flame retardant effect of the cable. The thickness of the shielding layer 302 is 1 mm, and it is made of copper wire. It is woven and covered on the outside of the insulating layer 301 to form a tight metal mesh. The higher the weaving density, the better the shielding effect. The copper wire shielding layer has good flexibility and conductivity. The thickness of the protective layer 303 is 1.5 mm, and it is made of rubber. It is sleeved on the outside of the shielding layer 302. Due to its soft and light characteristics, the cable can be moved frequently, which greatly improves the overall fireproof and heat-insulating effect of the cable.

[0023] Example 3: In order to effectively improve the tensile strength of the cable, Figure 1 and Figure 2 As shown, an armoring mechanism 4 is proposed, which is provided with a first armoring layer 401 and a second armoring layer 404. A plurality of card blocks 402 are installed on the first armoring layer 401, and a plurality of card slots 403 that fit with the plurality of card blocks 402 are opened on the inner side of the second armoring layer 404. The thickness of the first armoring layer 401 is 2 mm, and it is made of steel wire and is wound around the outside of the protective layer 303. The steel wire armor has high flexibility and tensile strength, and is suitable for cables that need to be frequently bent or moved. It can effectively prevent the cable from being stretched or twisted during movement, ensuring the stability of the internal structure of the cable. It also has good grounding performance, which helps to reduce electromagnetic interference. The thickness of the second armor layer 404 is 2mm. It is made of aluminum tape and is wrapped around the outside of the first armor layer 401. The aluminum tape is relatively light and has good corrosion resistance. It can enhance the cable's compressive strength and wear resistance. During long-term use, it can effectively reduce the friction and wear between the cable and the surrounding environment, reduce the risk of damage due to external force extrusion, thereby improving the overall tensile strength of the cable and ensuring the use effect of the power cable.
