Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an insulated windproof overhead cable. Background Art

[0002] When installing power cables, since the power cables themselves have a certain degree of flexibility, they need to be installed on bearing brackets with a certain distance between the bearing brackets. After the power cables are installed on the bearing brackets, the middle part of the power cables will sag, causing the middle part of the cables to be under greater pressure and prone to excessive deformation and damage. Therefore, an insulated windproof overhead cable is needed. Utility Model Content

[0003] The utility model aims to solve the problem in the prior art that after the cable is erected on a bearing bracket, the middle part of the power cable will sag, and an insulated windproof overhead cable is provided.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an insulated windproof overhead cable, comprising a cable body, an overhead mechanism is arranged on the outer wall of the cable body;

[0005] The overhead mechanism includes two support frames, two support legs are fixedly installed at the bottom ends of the two support frames, a first connecting rod is fixedly installed between the opposite sides of every two of the four support legs, two second connecting rods are fixedly installed between the opposite sides of the two first connecting rods, and a casing is fixedly installed between the opposite sides of the two second connecting rods, a threaded screw is movably inserted into the inner wall of the casing, and the outer wall of the threaded screw is threadedly connected to a slider, and the slider is movably inserted into the inner wall of the casing, and the cable body can be suspended through the support frame, and the rotation of the threaded screw can drive the slider to rise and fall.

[0006] Preferably, a support rod is fixedly installed on the top of the slider, and an arc-shaped support plate is fixedly installed on the top of the support rod. An arc-shaped rubber pad is arranged on the top of the arc-shaped support plate. The support rod and the arc-shaped support plate can be driven to rise and fall by the lifting and lowering of the slider. The arc-shaped rubber pad increases the friction force on the cable body. The arc-shaped support plate can effectively bear the weight of the cable body to prevent the cable body from excessively sagging and being damaged by excessive force. At the same time, the height of the arc-shaped support plate can be adjusted to keep the cable body in appropriate tension.

[0007] Preferably, a rotating plate is movably inserted at the bottom end of the casing, and the output shaft of the rotating plate passes through the inner wall of the casing and is fixedly connected to one end of the outer wall of the threaded screw, so that the rotating plate can drive the threaded screw to rotate.

[0008] Preferably, a core is arranged inside the cable body, an insulating layer is arranged on the outer wall of the core, a shielding layer is arranged on the outer wall of the insulating layer, the insulating layer has good electrical resistance and insulation performance, and the shielding layer can effectively shield most high-frequency electromagnetic radiation and external electromagnetic interference.

[0009] Preferably, a filling layer is provided on the outer wall of the shielding layer, and a waterproof layer is provided on the outer wall of the filling layer. Through the setting of the filling layer, the internal gaps of the cable body can be filled. The function of the filling layer is to evenly distribute the mechanical stress and provide buffering and support inside the cable body to enhance the compressive performance of the cable body.

The protective layer is mainly used to protect the internal components of the cable body from mechanical damage, environmental influences, chemical corrosion and other factors.

[0011] Preferably, the cable body is movably inserted into the inner walls of the two support frames.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the cable body is placed between two support frames, the middle part of the cable body may sag due to the certain length of the cable body. For a long time, the middle part of the cable may be subjected to greater pressure and prone to excessive deformation and damage. At this time, the rotating plate can be rotated, and the rotating plate drives the threaded screw to rotate. During the rotation process, the threaded screw drives the arc support plate to move upward through the slider and the support rod until it contacts the middle part of the cable body, thereby effectively bearing the weight of the cable body and avoiding excessive sagging and damage due to excessive force. At the same time, the height of the arc support plate can be adjusted to keep the cable body in proper tension. Appropriate tension can extend the service life of the cable body, reduce the risk of excessive force on the cable body, and reduce the possibility of breakage and damage.

[0014] 2. In the utility model, by setting the reinforcing ribs, the reinforcing ribs are usually a kind of metal wire or synthetic fiber, which is used to enhance the structural strength and tensile performance of the cable. Proper setting of the reinforcing ribs can improve the flexural performance of the cable, making it more flexible during installation and use, and reducing the risk of breakage. By setting the filling layer, the internal gaps of the cable can be filled. The function of the filling layer is to evenly distribute the mechanical stress, provide buffering and support inside the cable, so as to enhance the compressive performance of the cable and reduce the probability of the cable breaking due to excessive force on windy days.

At the same time, the height of the arc support plate 209 can be adjusted to keep the cable body 1 at an appropriate tension. Appropriate tension can extend the service life of the cable body 1, reduce the risk of excessive stress on the cable body 1, and reduce the possibility of breakage and damage. The reinforcement ribs 106 are arranged. The reinforcement ribs 106 are usually a metal wire or synthetic fiber, which is used to enhance the structural strength and tensile strength of the cable body 1. The appropriate arrangement of the reinforcement ribs 106 can improve the flexural performance of the cable body 1, making it more flexible during installation and use, and reducing the risk of breakage. The filling layer 104 can fill the internal gaps of the cable body 1. The filling layer 104 is used to evenly distribute mechanical stress, provide buffering and support inside the cable body 1, so as to enhance the compressive performance of the cable body 1, and reduce the probability of the cable body 1 being broken due to excessive stress on windy days.
