Description

Technical Field

[0001] The invention belongs to the technical field of cables, and more specifically, relates to a shear-resistant protective aluminum alloy cable. Background Art

[0002] Aluminum alloy power cable is a new type of power cable with aluminum alloy as conductor, special roll-formed wire stranding production process and annealing treatment and other advanced technologies. Aluminum alloy power cable makes up for the shortcomings of pure aluminum cables in the past. Although it does not improve the electrical conductivity of the cable, its bending performance, creep resistance and corrosion resistance are greatly improved, which can ensure that the cable maintains continuous performance stability when overloaded and overheated for a long time. However, the current aluminum alloy cable has poor shear resistance. When the cable is subjected to shear load during use, the cable is easily damaged, resulting in a shortened service life and the cable cannot work. Summary of the invention

[0003] The purpose of the present invention is to provide a shear-resistant protective aluminum alloy cable, aiming to solve the problem that the existing aluminum alloy cables have poor shear resistance.

[0004] To achieve the above object, the technical solution adopted by the present invention is: to provide a shear-resistant protective aluminum alloy cable, comprising: at least one conductor core; The supporting rubber strip is provided with at least one fixing hole; the conductive wire cores are passed through the fixing holes one by one; At least one first armor, sleeved on the supporting rubber strip; the outer diameter of one end of the first armor is smaller than the inner diameter of the other end; and At least one second armor is sleeved on the supporting rubber strip; the second armor has the same structure as the first armor; the thinner end of the second armor is inserted into the thicker end of the first armor; when the supporting rubber strip is bent, the adjacent first armor and second armor can slide. In a possible implementation, the first armor includes: An inner lining layer is sleeved on the supporting rubber strip; the diameter of one end of the inner lining layer is smaller than the diameter of the other end; and A plurality of armor sheets, one end of which is fixed on the inner lining layer, one side of which is inserted into the inner side of the adjacent armor sheet, and the armor sheet is covered on the outer peripheral surface of the inner lining layer; when the first armor is bent, the adjacent armor sheets can slide.

[0005] In a possible implementation, the armor sheet is an arc-shaped plate, the width of one end of the armor sheet is smaller than the width of the other end, and the end of the armor sheet with the smaller width is fixed to the inner lining layer.

[0006] In a possible implementation, the supporting rubber strip includes at least three supporting parts, the supporting parts abut against inner walls of the first armor and the second armor, and the fixing holes are arranged between the supporting parts.

[0007] In a possible implementation, it further includes a support ring sleeved on the support rubber strip, the support ring is arranged perpendicular to the support rubber strip, and the support ring is slidably matched with the first armor and the second armor.

[0008] In a possible implementation manner, a mounting groove is formed on the support portion, and the support ring is fixed in the mounting groove.

[0009] In a possible implementation manner, the outside of the conductor core is coated with an insulation layer.

[0010] In a possible implementation manner, a certain gap is provided between the insulating layer and the inner wall of the fixing hole.

[0011] In a possible implementation, it also includes a protective layer wrapped around the first armor and the second armor.

[0012] In a possible implementation, it further includes a plurality of protection wires arranged parallel to the axis of the support ring, and the protection wires are arranged along the circumference of the support ring; a plurality of mounting holes are provided on the support ring, and the protection wires are passed through the mounting holes one by one.

[0013] The beneficial effect of the shear-resistant protective aluminum alloy cable provided by the present invention is that, compared with the prior art, the conductor core is wrapped by the supporting rubber strip, the first armor and the second armor. When a shear force is received, most of the shear force is transmitted to the supporting rubber strip through the first armor or the second armor, and the shear force applied to the conductor core is small, so the shear force has little effect on the conductor core.

[0014] When laying a cable, it is usually necessary to bend it. Since the first armor and the second armor are not fixedly connected, when the cable is bent, the first armor and the second armor slide between them, so that the first armor and the second armor can bend with the cable. When laying the cable, it can be ensured that the cable can be bent as required. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Reference Figure 1 and Figure 4 , the shear-resistant protective aluminum alloy cable provided by the present invention is now described.

[0020] Reference Figure 1 and 2 An embodiment of the present invention provides a shear-resistant protective aluminum alloy cable, comprising: at least one conductor core 1, a supporting rubber strip 2, at least one first armor 3 and at least one second armor 4.

[0021] The supporting rubber strip 2 is provided with at least one fixing hole 21; the conductor cores 1 are passed through the fixing holes 21 in a one-to-one correspondence. The first armor 3 is sleeved on the supporting rubber strip 2; the outer diameter of one end of the first armor 3 is smaller than the inner diameter of the other end. The second armor 4 is sleeved on the supporting rubber strip 2; the second armor 4 has the same structure as the first armor 3; the thinner end of the second armor 4 is inserted into the thicker end of the first armor 3. A certain gap is provided between the first armor 3 and the second armor 4, and the first armor 3 and the second armor 4 have a certain elasticity and can undergo a certain deformation. When the supporting rubber strip 2 is bent, the adjacent first armor 3 and the second armor 4 slide to meet the bending requirements of the cable.

[0022] Compared with the prior art, the shear-resistant protective aluminum alloy cable provided by the present invention has the same number of first armors 3 as that of second armors 4, and the first armors 3 and the second armors 4 are connected end to end. The first armors 3 and the second armors 4 protect the conductor core 1 inside. When the cable body receives shear force, the shear force first acts on the first armor 3 and the second armor 4. Most of the shear force is absorbed by the first armor 3 and the second armor 4, and the remaining shear force is transmitted to the supporting rubber strip 2 through the first armor 3 or the second armor 4. Most of the shear force is borne by the first armor 3 and the second armor 4 and the supporting rubber strip 2, and the remaining small part of the shear force acts on the conductor core 1, thereby reducing the damage to the conductor core 1 caused by the shear force.

[0023] When laying cables, the cables usually need to be bent according to environmental conditions. When the shear-resistant protective aluminum alloy cable provided by the embodiment of the present invention is bent, the conductor core 1 and the supporting rubber strip 2 can be bent according to demand. Since a certain gap is reserved between the first armor 3 and the second armor 4, and the first armor 3 and the second armor 4 can be elastically deformed, when the conductor core 1 and the supporting rubber strip 2 are bent, sliding and elastic deformation occur between the first armor 3 and the second armor 4 at the bending part, thereby meeting the bending requirements of the supporting rubber strip 2 and the conductor core 1, and ensuring that the supporting rubber strip 2 and the conductor core 1 can be bent smoothly.

[0024] Reference Figure 3 In a possible implementation, the first armor 3 includes an inner lining layer 31 and a plurality of armor sheets 32. The inner lining layer 31 is sleeved on the supporting rubber strip 2; the diameter of one end of the inner lining layer 31 is smaller than the diameter of the other end. One end of the armor sheet 32 ​​is fixed on the inner lining layer 31, one side of the armor sheet 32 ​​is inserted into the inner side of the adjacent armor sheet 32, and the armor sheet 32 ​​is covered on the outer peripheral surface of the inner lining layer 31; when the first armor 3 is bent, the adjacent armor sheets 32 slide.

When the mounting portion receives a torque, it can rotate around its own axis in the through hole. The armor sheet 32 ​​is installed on the inner lining layer 31 through the cooperation of the mounting portion and the through hole.

In this process, the armor sheets 32 located on both sides of the bending direction slide with the armor sheets 32 located in the bending direction and the armor sheets 32 located on the back of the bending, so that the armor sheets 32 will not hinder the bending of the inner lining layer 31, the supporting rubber strip 2 and the conductor core 1. At the same time, the armor sheets 32 have a certain elasticity. When the shear-resistant protective aluminum alloy cable provided in the embodiment of the present invention is bent, if the movement of the armor sheets 32 reaches the limit, the armor sheets 32 can be deformed to a certain extent to meet the bending requirements.

When the mounting portion receives a torque, it can rotate around its own axis in the through hole. The armor sheet 32 ​​is installed on the inner lining layer 31 through the cooperation of the mounting portion and the through hole.

[0037] When the inner lining layer 31 bends along with the supporting rubber strip 2 and the conductor core 1, the armor sheet 32 ​​located in the bending direction naturally rises, and the armor sheets 32 located on both sides of the bending direction can rotate in the through hole. In this process, the armor sheets 32 located on both sides of the bending direction slide with the armor sheets 32 located in the bending direction and the armor sheets 32 located on the back of the bending, so that the armor sheets 32 will not hinder the bending of the inner lining layer 31, the supporting rubber strip 2 and the conductor core 1.

When the shear-resistant protective aluminum alloy cable provided in the embodiment of the present invention is bent, if the movement of the armor sheets 32 reaches the limit, the armor sheets 32 can be deformed to a certain extent to meet the bending requirements.

[0039] The material of the supporting rubber strip 2 is natural rubber, which has certain elasticity and high hardness. When the cable as a whole receives shear force, most of the shear force is borne by the first armor 3 and the second armor 4, and part of the shear force is transmitted to the supporting rubber strip 2 through the first armor 3 and the second armor 4. The supporting rubber strip 2 with higher hardness bears most of the transmitted shear force. At the same time, the supporting rubber strip 2 has certain elasticity and can be elastically deformed to meet the bending requirements of the cable.

[0044] In a preferred embodiment, the support ring 5 is made of stainless steel with high hardness. After part of the shear force is transmitted to the support rubber strip 2 through the first armor 3 and the second armor 4, the support ring 5 will bear part of the transmitted shear force, reduce the shear force borne by the support rubber strip 2, and protect the support rubber strip 2 and the conductor core 1.

[0045] In a preferred embodiment, the support ring 5 is made of engineering plastic material with high hardness. After part of the shear force is transmitted to the support rubber strip 2 through the first armor 3 and the second armor 4, the support ring 5 will bear part of the transmitted shear force, reduce the shear force borne by the support rubber strip 2, and protect the support rubber strip 2 and the conductor core 1.

[0046] In a preferred embodiment, the support ring 5 is made of aluminum alloy and has high hardness. At the same time, a circle of reinforcing ribs is provided on the inner wall of the support ring 5. The reinforcing ribs further increase the hardness of the support ring 5.

[0047] In a possible implementation, the outside of the conductor core 1 is covered with an insulating layer 6 .

[0048] In a possible implementation, a certain gap is provided between the insulating layer 6 and the inner wall of the fixing hole 21. When the cable body is bent, the conductor core 1 and the supporting rubber strip 2 have different tensile properties, resulting in a difference in the stretching amount of the two. During this process, the conductor core 1 and the supporting rubber strip 2 will undergo relative displacement. A movable gap is provided between the insulating layer 6 and the inner wall of the fixing hole 21 to satisfy the relative displacement between the conductor core 1 and the supporting rubber strip 2.

[0049] In a possible implementation, it further includes a protective layer 7 covering the outside of the first armor 3 and the second armor 4 .

[0050] The protective layer 7 is sleeved on the outside of the first armor 3 and the second armor 4, so that each armor sheet 32 ​​fits on the inner lining layer 31. When the cable body is bent, the armor sheet 32 ​​located at the back of the bending direction can fit on the inner lining layer 31, so that the overall structure of the cable remains compact. At the same time, the protective layer 7 wraps up each armor sheet 32, which can prevent sand and gravel in the environment from entering the gaps between the armor sheets 32 and the gaps between the first armor 3 and the second armor 4, and generating unnecessary wear when the first armor 3 and the second armor 4 move and the elder armor sheet 32 ​​moves. At the same time, it can prevent debris from getting stuck in the first armor 3 and the second armor 4, and each armor sheet 32, thereby preventing the bending performance of the cable from being affected.

[0051] In a possible implementation, it further includes a plurality of protection wires 8 arranged parallel to the axis of the support ring 5, and the protection wires 8 are arranged along the circumference of the support ring 5; the support ring 5 is provided with a plurality of mounting holes 51, and the protection wires 8 are correspondingly passed through the mounting holes 51. The protection wires 8 connect the support rings 5 ​​as a whole, and when the shear force is transmitted from between two support rings 5 ​​to the support rubber strip 2, the shear force is dispersed to the adjacent support rings 5 ​​through the protection wires 8, further reducing the shear force transmitted to the support rubber strip 2.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
