Description

Technical Field

[0001] This invention relates to the field of cable protection technology, and in particular to a cable with high-efficiency protection capabilities. Background Technology

[0002] In the existing technology, cables are laid in areas that need to withstand the pressure of heavy objects (compression zones). For such areas, protection is required after the cable is laid to avoid damage caused by compression. In the existing technology, cement is poured directly onto the surface of the cable for protection. However, when the cement block is cracked or the temperature difference causes the cement block to expand and contract, the cable inside the cement block will be subjected to hard pulling, thus being damaged.

[0003] In addition, in the existing technology, some cable laying scenarios are only for temporary use, and it is inconvenient to use cement for protection, so they are only covered with soil. Summary of the Invention

[0004] To overcome the shortcomings mentioned in the background art, the present invention provides: a cable with high-efficiency protection capability, including a first fixing plate; a bending section is provided on the cable body, the bending section is placed in the pressure-resistant area; a first fixing plate is provided on each side of the bending section of the cable body, the first fixing plate is fixed to the cable body by a first fixing device; a round pipe is fixed to each of the two first fixing plates facing each other; the bending section is closed and protected by the connection of the two round pipes.

[0005] More preferably, the inner diameter of the circular tube is larger than the outer diameter of the cable body.

[0006] More preferably, when the cable laying site can be protected with cement, after burying the cable body and the round pipe in the cable trench, cement is poured on the outside of the round pipe for protection.

[0007] More preferably, a second fixing plate is fixed to each side of the curved section of the cable body by a second fixing device; the second fixing plate is located between the two round pipes; a support plate is detachably connected between the two second fixing devices.

[0008] More preferably, each of the two second fasteners has multiple diagonal braces fixed to its opposite side.

[0009] More preferably, the support plate is designed with an upward arched shape.

[0010] More preferably, when the support plate is insufficient to support the pressure applied from above, its lateral span increases.

[0011] More preferably, when cement cannot be used to protect the cable laying site, soil is not injected into the round pipe, and a support plate is installed on the upper side of the curved section of the cable body for protection.

[0012] More preferably, when the two second fixing plates are squeezed apart and moved, the bent section is straightened, and the cable between the first fixing device and the second fixing device is squeezed and bent in the round tube.

[0013] The advantages of this invention are as follows: For scenarios where cement protection can be used, the outer diameter of the circular tube and the cement layer combine to form a rigid outer shell. The inner diameter of the circular tube is larger than that of the cable and the bending section, which avoids the problem of rigid tension caused by thermal expansion and contraction or cracking of cement. For temporary laying scenarios without cement, the span of the support plate adaptively expands when it is under pressure, driving the second fixing plates on both sides to move away from each other, simultaneously straightening the bending section to release pressure, and squeezing and storing the cable inside the circular tube, thus achieving efficient protection of the cable.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: As Figures 1-2 As shown, the present invention provides: a cable with high-efficiency protection capability, including a first fixing plate 1, a first fixing device 2, and a round tube 3; a bending section 100a is provided on the cable body 100, and the bending section 100a is placed in the pressure-resistant area; a first fixing plate 1 is provided on each side of the bending section 100a of the cable body 100, and the first fixing plate 1 is fixed to the cable body 100 by the first fixing device 2; a round tube 3 is fixed to each of the two first fixing plates 1 facing each other; the bending section 100a is sealed and protected by the two round tubes 3 being joined together.

[0019] The inner diameter of the circular tube 3 is larger than the outer diameter of the cable body 100.

[0020] When the cable laying site can be protected with cement, after burying the cable body 100 and the round pipe 3 in the cable trench, pour cement on the outside of the round pipe 3 for protection.

[0021] In the existing technology, cables are laid in areas that need to withstand the pressure of heavy objects (compression zones). For such areas, protection is required after the cable is laid to avoid damage caused by compression. In the existing technology, cement is poured directly onto the surface of the cable for protection. However, when the cement block is cracked or the temperature difference causes the cement block to expand and contract, the cable inside the cement block will be subjected to hard pulling, thus being damaged.

[0022] Based on the above structure and problems, the working principle of this invention is as follows:

[0023] Firstly, in this invention, a bending section 100a is provided in the middle of the cable body 100, and the bending section 100a is placed in the pressure-resistant area. Then, the first fixing plate 1 is fixed to both ends of the bending section 100a by the first fixing device 2. At this time, the two round tubes 3 are connected together and the bending section 100a is sealed and protected. Then, cement is poured on the outside of the round tubes 3 for protection. After the cement solidifies, even if the cement block expands and contracts due to heat or cannot withstand the pressure and cracks, the cable inside the round tubes 3 will be automatically straightened or bent because it is set in a bent shape, so as not to cause damage to the cable and greatly improve the protection capability of the cable.

[0024] Furthermore, a second fixing plate 4 is fixedly connected to each side of the curved section 100a of the cable body 100 by a second fixing device 5; the second fixing plate 4 is located between the two round tubes 3; a support plate 7 is detachably connected between the two second fixing devices 5.

[0025] Each of the two second fasteners 5 is fixed with multiple diagonal rods 6 on opposite sides, thereby increasing the fixing strength of the second fasteners 5.

[0026] The support plate 7 is designed with an upward arched shape.

[0027] When the support plate 7 is insufficient to support the pressure applied from above, its lateral span increases.

[0028] When the cable laying site cannot be protected with cement, soil is not injected into the circular pipe 3, and a support plate 7 is installed on the upper side of the curved section 100a of the cable body 100 for protection.

[0029] When the two second fixing plates 4 are squeezed apart and moved, the bent section 100a is straightened, and the cable between the first fixing device 2 and the second fixing device 5 is squeezed and bent in the round tube 3.

[0030] In addition, in the existing technology, some cable laying scenarios are only for temporary use, and it is inconvenient to use cement for protection, so only soil is used to cover them;

[0031] Based on the above structure and problems, the working principle of this invention is as follows:

[0032] On both sides of the bent section 100a of the cable body 100, a second fixing plate 4 is fixed by a second fixing device 5. The second fixing plate 4 is located between two circular pipes 3, and a support plate 7 is installed between the two second fixing devices 5. When the cable is laid, except for the space inside the circular pipe 3, the rest of the components are covered with soil. When a heavy object presses down, it is supported by the support plate 7 which has an upward arch shape. When the support plate 7 is insufficient to support the pressure applied from above, its left and right spans increase, which in turn causes the two second fixing plates 4 to move apart. At this time, the bent section 100a is straightened and is not crushed by the pressure. At the same time, the cable between the first fixing device 2 and the second fixing device 5 is crushed and bent in the circular pipe 3 for protection.

[0033] In the above, the present invention addresses scenarios where cement protection can be used. The outer diameter of the circular tube 3 is combined with the cement layer to form a rigid shell. The inner diameter of the circular tube 3 is larger than that of the cable and the bending section 100a, thus avoiding the problem of rigid pulling caused by the thermal expansion and contraction or cracking of the cement. For temporary laying scenarios without cement, the span of the support plate 7 adaptively expands when it is under pressure, driving the second fixing plates 4 on both sides to move away from each other, simultaneously straightening the bending section 100a to release the pressure, and squeezing and storing the cable inside the circular tube 3, thus achieving efficient protection of the cable.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
