Description

Technical Field

[0001] The present 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 cables are new material power cables with aluminum alloy materials as conductors, adopting advanced technologies such as special roll-forming type wire stranding production processes and annealing treatments. Aluminum alloy power cables make up for the deficiencies of previous pure aluminum cables. Although they do not improve the electrical conductivity of the cables, their bending performance, anti-creep performance, and corrosion resistance are greatly improved, and they can ensure the continuous performance stability of the cables during long-term overload and overheating. However, the current aluminum alloy cables have poor shear resistance. When the cables are subjected to shear loads during use, the cables are easily damaged, resulting in shortened service life and the cables being unable to 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 of poor shear resistance of existing aluminum alloy cables.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a shear-resistant protective aluminum alloy cable, including:

[0005] At least one conductor core;

[0006] Support rubber strips, provided with at least one fixing hole; the conductor cores are respectively inserted into the fixing holes in a one-to-one correspondence;

[0007] At least one first armor, sleeved on the support rubber strip; the outer diameter of one end of the first armor is smaller than the inner diameter of the other end; and

[0008] At least one second armor, sleeved on the support 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 support rubber strip is bent, the adjacent first armor and the second armor can slide.

[0009] In a possible implementation manner, the first armor includes:

[0010] An inner liner, sleeved on the support rubber strip; the diameter of one end of the inner liner is smaller than the diameter of the other end; and

[0011] A plurality of armor plates, one end of which is fixed on the inner liner, one side of the armor plate is inserted into the inside of the adjacent armor plate, and the armor plates cover the outer peripheral surface of the inner liner; when the first armor is bent, the adjacent armor plates can slide.

[0012] In a possible implementation, the armored sheet is an arc-shaped plate, one end of the armored sheet has a smaller width than the other end, and the end with the smaller width of the armored sheet is fixed on the inner lining layer.

[0013] In a possible implementation, the support rubber strip includes at least three support portions, the support portions abut against the inner walls of the first armor and the second armor, and the fixing holes are arranged between the support portions.

[0014] 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 in sliding fit with the first armor and the second armor.

[0015] In a possible implementation, an installation groove is formed on the support portion, and the support ring is fixed in the installation groove.

[0016] In a possible implementation, an insulating layer is coated on the outside of the wire core.

[0017] In a possible implementation, there is a certain gap between the insulating layer and the inner wall of the fixing hole.

[0018] In a possible implementation, it further includes a protective layer coated on the outside of the first armor and the second armor.

[0019] In a possible implementation, it further includes a plurality of protective wires arranged parallel to the axis of the support ring, and the protective wires are arranged in a circle along the circumferential direction of the support ring; a plurality of installation holes are provided on the support ring, and the protective wires are respectively inserted into the installation holes.

[0020] The beneficial effects of the anti-shear protective aluminum alloy cable provided by the present invention are as follows: Compared with the prior art, the wire core is wrapped by the support rubber strip, the first armor and the second armor. When a shearing force is received, most of the shearing force is transmitted to the support rubber strip through the first armor or the second armor, and the shearing force received by the wire core is smaller. Therefore, the influence of the shearing force on the wire core is smaller.

[0021] When laying the cable, it usually needs to be bent. 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 relative to each other, so that the first armor and the second armor can bend along with the cable. When laying the cable, it can be ensured that the cable can be bent according to requirements. Description of the Drawings

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the following further details the present invention with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Refer to Figure 1 and Figure 4 , and now the shear-resistant protective aluminum alloy cable provided by the present invention will be described.

[0031] Refer to Figure 1 and 2 , a shear-resistant protective aluminum alloy cable provided by an embodiment of the present invention includes: at least one conductor core 1, a support rubber strip 2, at least one first armor 3 and at least one second armor 4.

[0032] The support rubber strip 2 is provided with at least one fixing hole 21; the wire cores 1 are respectively inserted into the fixing holes 21 in a one-to-one correspondence. The first armor 3 is sleeved on the support 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 support 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. There is a certain gap between the first armor 3 and the second armor 4, and at the same time, the first armor 3 and the second armor 4 have a certain elasticity and can undergo a certain deformation. When the support rubber strip 2 bends, the adjacent first armor 3 and second armor 4 slide to meet the requirements of cable bending.

[0033] For the anti-shear protective aluminum alloy cable provided by the present invention, compared with the prior art, the number of the first armors 3 is the same as that of the 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 wire cores 1 inside. When the cable body receives a shearing force, the shearing force first acts on the first armors 3 and the second armors 4. Most of the shearing force is absorbed by the first armors 3 and the second armors 4, and the remaining shearing force is transmitted to the support rubber strip 2 through the first armor 3 or the second armor 4. Most of the shearing force is borne by the first armors 3, the second armors 4 and the support rubber strip 2, and the remaining small part of the shearing force acts on the wire cores 1, reducing the damage to the wire cores 1 caused by the shearing force.

[0034] When laying the cable, the cable usually needs to be bent according to the environmental conditions. When the anti-shear protective aluminum alloy cable provided by the embodiment of the present invention bends, the wire cores 1 and the support rubber strip 2 can bend according to the requirements. Since there is a certain gap reserved between the first armor 3 and the second armor 4, and at the same time, both the first armor 3 and the second armor 4 can elastically deform, when the wire cores 1 and the support rubber strip 2 bend, sliding and elastic deformation occur between the first armor 3 and the second armor 4 at the bending part, so as to meet the bending requirements of the support rubber strip 2 and the wire cores 1 and ensure that the support rubber strip 2 and the wire cores 1 can bend smoothly.

[0035] Refer to Figure 3 , in a possible implementation manner, the first armor 3 includes an inner lining layer 31 and a plurality of armor plates 32. The inner lining layer 31 is sleeved on the support rubber strip 2; the diameter of one end of the inner lining layer 31 is smaller than that of the other end. One end of the armor plate 32 is fixed on the inner lining layer 31, one side of the armor plate 32 is inserted into the inside of the adjacent armor plate 32, and the armor plate 32 covers the outer peripheral surface of the inner lining layer 31; when the first armor 3 bends, the adjacent armor plates 32 slide.

[0036] In a possible implementation manner, the armor plate 32 is an arc-shaped plate, the width of one end of the armor plate 32 is smaller than that of the other end, and the end with a smaller width of the armor plate 32 is fixed on the inner lining layer 31.

[0037] In a preferred embodiment, the inner lining 31 is a rubber hose, and the function of the inner lining 31 is to fix the armor sheet 32. The inner lining 31 is in the shape of a trumpet, and the thickness of the inner lining 31 is the same at all places. The inner diameter and outer diameter of one end are smaller than the inner diameter and outer diameter of the other end, and the outer diameter of the thinner end of the inner lining 31 is smaller than the outer diameter of the other end. The length of the armor sheet 32 ​​is the same as that of the inner lining 31, and one side of the armor sheet 32 ​​is inserted into the gap between the adjacent armor sheet 32 ​​and the inner lining 31. And all the armor sheets 32 are arranged in this way on the outer peripheral surface of the inner lining 31 to form a curved surface.

[0038] A through hole is provided on the side wall of the end with a smaller inner diameter of the inner lining layer 31, and the number of the through holes is the same as the number of the armor sheets 32, and they correspond one to one. The armor sheet 32 ​​is an arc-shaped stainless steel plate, and a mounting portion is provided at the end with a smaller width of the armor sheet 32. The mounting portion is cylindrical, and the diameter of the mounting portion is slightly larger than the diameter of the through hole. After the mounting portion is inserted into the through hole, the mounting portion is fixed in the through hole under the action of friction. 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.

[0039] 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. 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.

[0040] In a preferred embodiment, the inner lining 31 is a hose made of soft plastic, and the function of the inner lining 31 is to fix the armor sheet 32. The inner lining 31 is in the shape of a trumpet, and the thickness of the inner lining 31 is the same at all places. The inner diameter and outer diameter of one end are smaller than the inner diameter and outer diameter of the other end, and the outer diameter of the thinner end of the inner lining 31 is smaller than the outer diameter of the other end. The length of the armor sheet 32 ​​is the same as that of the inner lining 31, and one side of the armor sheet 32 ​​is inserted into the gap between the adjacent armor sheet 32 ​​and the inner lining 31. And all the armor sheets 32 are arranged in this way on the outer peripheral surface of the inner lining 31 to form a curved surface.

[0041] A through hole is provided on the side wall of the smaller-diameter end of the inner lining layer 31. The number of through holes is the same as the number of armored sheets 32 and they correspond one by one. The armored sheet 32 is an arc-shaped stainless steel plate, and an installation part is provided at the end with a smaller width of the armored sheet 32. The shape of the installation part is cylindrical, and the diameter of the installation part is slightly larger than the diameter of the through hole. After the installation part is inserted into the through hole, under the action of friction, the installation part is fixed in the through hole. When the installation part receives a moment, it can rotate around its own axis in the through hole. The armored sheet 32 is installed on the inner lining layer 31 through the cooperation of the installation part and the through hole.

[0042] When the inner lining layer 31 bends along with the support rubber strip 2 and the wire core 1, the armored sheet 32 located in the bending direction naturally warps up, and the armored sheets 32 located on both sides of the bending direction can rotate in the through holes. During this process, the armored sheets 32 located on both sides of the bending direction slide with the armored sheet 32 located in the bending direction and the armored sheet 32 located on the back of the bending, so that the armored sheet 32 does not hinder the bending of the inner lining layer 31, the support rubber strip 2 and the wire core 1. At the same time, the armored sheet 32 has a certain elasticity. When the anti-shear protection type aluminum alloy cable provided in the embodiment of the present invention bends, if the movement amount of the armored sheet 32 reaches the limit, the armored sheet 32 can undergo a certain amount of deformation to meet the bending requirements.

[0043] In a preferred embodiment, the inner lining layer 31 is a rubber hose, and the function of the inner lining layer 31 is to fix the armored sheet 32. The shape of the inner lining layer 31 is trumpet-shaped, and the thickness of each part of the inner lining layer 31 is the same. The inner diameter and outer diameter of one end of the inner lining layer 31 are both smaller than the inner diameter and outer diameter of the other end. At the same time, the outer diameter of the thinner end of the inner lining layer 31 is smaller than the outer diameter of the other end. The length of the armored sheet 32 is the same as the length of the inner lining layer 31, and one side of the armored sheet 32 is inserted into the gap between the adjacent armored sheet 32 and the inner lining layer 31. And all the armored sheets 32 are arranged in a circle on the outer peripheral surface of the inner lining layer 31 in this way to form a curved surface.

[0044] A through hole is provided on the side wall of the smaller-diameter end of the inner lining layer 31. The number of through holes is the same as the number of armored sheets 32 and they correspond one by one. The armored sheet 32 is an arc-shaped engineering plastic plate with good structural strength, and an installation part is provided at the end with a smaller width of the armored sheet 32. The shape of the installation part is cylindrical, and the diameter of the installation part is slightly larger than the diameter of the through hole. After the installation part is inserted into the through hole, under the action of friction, the installation part is fixed in the through hole. When the installation part receives a moment, it can rotate around its own axis in the through hole. The armored sheet 32 is installed on the inner lining layer 31 through the cooperation of the installation part and the through hole.

[0045] When the inner liner 31 bends along with the support rubber strip 2 and the wire core 1, the armor plates 32 located in the bending direction naturally tilt up, and the armor plates 32 located on both sides of the bending direction can rotate in the through holes. During this process, the armor plates 32 on both sides of the bending direction slide against the armor plates 32 in the bending direction and the armor plates 32 on the back of the bend, so that the armor plates 32 do not hinder the bending of the inner liner 31, the support rubber strip 2, and the wire core 1. At the same time, the armor plates 32 have a certain elasticity. When the anti-shear protective aluminum alloy cable provided in the embodiment of the present invention bends, if the movement amount of the armor plates 32 reaches the limit, the armor plates 32 can undergo a certain amount of deformation to meet the bending requirements.

[0046] In a preferred embodiment, the inner liner 31 is a rubber tube made of soft plastic, and the function of the inner liner 31 is to fix the armor plates 32. The shape of the inner liner 31 is trumpet-shaped, and the thickness of the inner liner 31 is the same everywhere. The inner diameter and outer diameter of one end of the inner liner 31 are both smaller than the inner diameter and outer diameter of the other end. At the same time, the outer diameter of the thinner end of the inner liner 31 is smaller than the outer diameter of the other end. The length of the armor plates 32 is the same as the length of the inner liner 31, and one side of the armor plates 32 is inserted into the gap between adjacent armor plates 32 and the inner liner 31. And all the armor plates 32 are arranged in a circle on the outer peripheral surface of the inner liner 31 in this way, enclosing a curved surface.

[0047] Through holes are provided on the side wall of the end of the inner liner 31 with a smaller inner diameter. The number of through holes is the same as the number of armor plates 32 and they correspond one by one. The armor plates 32 are arc-shaped engineering plastic plates with good structural strength. Installation parts are provided at the ends of the armor plates 32 with a smaller width. The shape of the installation parts is cylindrical, and the diameter of the installation parts is slightly larger than the diameter of the through holes. After the installation parts are inserted into the through holes, under the action of friction, the installation parts are fixed in the through holes. When the installation parts receive a torque, they can rotate around their own axes in the through holes. The armor plates 32 are installed on the inner liner 31 through the cooperation of the installation parts and the through holes.

[0048] When the inner liner 31 bends along with the support rubber strip 2 and the wire core 1, the armor plates 32 located in the bending direction naturally tilt up, and the armor plates 32 located on both sides of the bending direction can rotate in the through holes. During this process, the armor plates 32 on both sides of the bending direction slide against the armor plates 32 in the bending direction and the armor plates 32 on the back of the bend, so that the armor plates 32 do not hinder the bending of the inner liner 31, the support rubber strip 2, and the wire core 1. At the same time, the armor plates 32 have a certain elasticity. When the anti-shear protective aluminum alloy cable provided in the embodiment of the present invention bends, if the movement amount of the armor plates 32 reaches the limit, the armor plates 32 can undergo a certain amount of deformation to meet the bending requirements.

[0049] In a possible implementation, the support rubber strip 2 includes at least three support portions 22, the support portions 22 are abutted against the inner walls of the first armor 3 and the second armor 4, and the fixing holes 21 are arranged between the support portions 22.

[0050] The material of the support rubber strip 2 is natural rubber, which has certain elasticity and relatively high hardness. When the cable as a whole is subjected to a shearing force, most of the shearing force is borne by the first armor 3 and the second armor 4, and a part of the shearing force will be transmitted to the support rubber strip 2 through the first armor 3 and the second armor 4. Then, the support rubber strip 2 with relatively high hardness bears most of the transmitted shearing force. At the same time, the support rubber strip 2 has certain elasticity and can undergo elastic deformation to meet the bending requirements of the cable.

[0051] The material of the support rubber strip 2 is nitrile rubber, which has certain elasticity and relatively high hardness. When the cable as a whole is subjected to a shearing force, most of the shearing force is borne by the first armor 3 and the second armor 4, and a part of the shearing force will be transmitted to the support rubber strip 2 through the first armor 3 and the second armor 4. Then, the support rubber strip 2 with relatively high hardness bears most of the transmitted shearing force. At the same time, the support rubber strip 2 has certain elasticity and can undergo elastic deformation to meet the bending requirements of the cable.

[0052] The material of the support rubber strip 2 is neoprene, which has certain elasticity and relatively high hardness. When the cable as a whole is subjected to a shearing force, most of the shearing force is borne by the first armor 3 and the second armor 4, and a part of the shearing force will be transmitted to the support rubber strip 2 through the first armor 3 and the second armor 4. Then, the support rubber strip 2 with relatively high hardness bears most of the transmitted shearing force. At the same time, the support rubber strip 2 has certain elasticity and can undergo elastic deformation to meet the bending requirements of the cable.

[0053] Refer to Figure 4 In a possible implementation, it further includes a support ring 5 sleeved on the support rubber strip 2. The support ring 5 is arranged perpendicular to the support rubber strip 2, and the support ring 5 is in sliding fit with the first armor 3 and the second armor 4.

[0054] In a possible implementation, an installation groove 23 is formed on the support portion 22, and the support ring 5 is fixed in the installation groove 23.

[0055] In a preferred embodiment, the material of the support ring 5 is stainless steel, which has relatively high hardness. After part of the shearing 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 shearing force, reduce the shearing force borne by the support rubber strip 2, and protect the support rubber strip 2 and the wire core 1.

[0056] In a preferred embodiment, the support ring 5 is made of engineering plastic material and has a relatively 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 wire core 1.

[0057] In a preferred embodiment, the support ring 5 is made of aluminum alloy material and has a relatively high hardness. At the same time, a reinforcing rib is provided on the inner wall of the support ring 5. The reinforcing rib further improves the hardness of the support ring 5. 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 wire core 1.

[0058] In a possible implementation, an insulating layer 6 is coated on the outside of the wire core 1.

[0059] 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, due to the different tensile resistance properties of the wire core 1 and the support rubber strip 2, there is a difference in the amount of stretching between the two. During this process, relative displacement will occur between the wire core 1 and the support rubber strip 2. The moving gap provided between the insulating layer 6 and the inner wall of the fixing hole 21 satisfies the relative displacement between the wire core 1 and the support rubber strip 2.

[0060] In a possible implementation, a protective layer 7 is further included, which is coated on the outside of the first armor 3 and the second armor 4.

[0061] The protective layer 7 is sleeved on the outside of the first armor 3 and the second armor 4, so that each armor piece 32 fits on the inner lining layer 31. When the cable body is bent, the armor piece 32 located on the back of the bending direction can fit on the inner lining layer 31, keeping the overall structure of the cable compact. At the same time, the protective layer 7 wraps each armor piece 32, which can prevent sundries such as grit in the environment from entering the gaps between the armor pieces 32 and the gaps between the first armor 3 and the second armor 4, causing unnecessary wear when the first armor 3 and the second armor 4 move and each armor piece 32 moves. At the same time, it can prevent sundries from jamming the first armor 3 and the second armor 4 and each armor piece 32, thereby avoiding affecting the bending performance of the cable.

[0062] 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 in a circle along the circumferential direction of the support ring 5; a plurality of mounting holes 51 are provided on the support ring 5, and the protection wires 8 are respectively inserted into the mounting holes 51. The protection wires 8 connect the respective support rings 5 into a whole. When the shear force is transmitted from between the 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.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
