In the present utility model, "horizontal" and "vertical" are used to describe a general positional relationship, and are not strictly "horizontal" or "vertical".
Referring to fig. 1-2, a fracture monitoring and reinforcing structure for a cable conductor according to a preferred embodiment is shown, comprising: the function wire 310 located at the inner side is wound around the plurality of monitoring wires 210 and the insulating rubber 110 covering the function wire 310 and the monitoring wires 210.
Further, as a preferred embodiment, the center of the insulating rubber 110 has a first hole through which the functional wire 310 passes.
Further, as a preferred embodiment, the middle portion of the insulating rubber 110 has a plurality of second holes through which the monitoring wires 210 pass.
Further, as a preferred embodiment, a plurality of second holes are arranged around the first hole.
Further, as a preferred embodiment, the monitor line 210 is a conductor.
Further, as a preferred embodiment, the strength of the monitoring line 210 is greater than the strength of the insulating rubber 110.
Further, as a preferred embodiment, the monitor wire 210 is spaced from the outer edge of the insulating rubber 110.
Further, as a preferred embodiment, the method further comprises: the upper computer 410 and the lower computer 510, and two ends of each monitoring line 2 are connected with the upper computer 410 and the lower computer 510.
Further, as a preferred embodiment, the insulating rubber 110 and the monitoring line 210 primarily take on traction.
Further, as a preferred embodiment, the monitoring line 210 functions to monitor cable breakage.
Further, as a preferred embodiment, the function wire 310 does not take on traction, and the function wire 310 functions as a function cable for power supply or communication.
Further, as a preferred embodiment, the present utility model provides a fracture monitoring method wherein the monitoring line 210 is a conductor, preferably steel wire, copper wire or carbon fiber.
Specifically, the lower computer 510 outputs a high level signal in real time. When the monitor line 210 connects the upper computer 410 and the lower computer 510, the upper computer 410 can obtain the high level signal output by the lower computer 510 due to the connection of the line.
Specifically, when the cable wire breaks due to frictional wear or pulling, the monitoring wire 210 eventually breaks. At this time, the upper computer 410 and the lower computer 510 are disconnected to obtain a low level signal, so as to know the breakage of the monitoring line of the channel.
Further, as a preferred embodiment, since the monitoring wires 210 are uniformly distributed in the insulating rubber 110 in a ring shape, the upper computer 410 can monitor the current damage or breakage of the cable in real time according to the broken positions and number of the monitoring wires 210.
Further, as a preferred embodiment, the greater the number of monitor lines 210 distributed, the greater the accuracy of the monitoring,
Further, as a preferred embodiment, in terms of structural reinforcement, since the monitoring wire 210 is made of a material having much higher strength than the insulating rubber 110, such as steel wire or carbon fiber. According to the mechanics of the composite material, the monitoring wires 210 play a role in reinforcing and toughening, and bear the load together with the insulating rubber 110.
Further, as a preferred embodiment, by designing the distance x of the monitoring line 210 from the edge of the insulating rubber 110, the allowable thickness of the cable wear can be controlled;
Further, as a preferred embodiment, by the diameter a of the cable, the diameter B of the functional layer, the number n of the monitoring wires and the diameter d, according to the following composite mechanical formulas (1) and (2), the pulling forces F 1、F2 and F 3 respectively applied to the insulating rubber 110, the monitoring wires 210 and the functional wires 110 under a given load F can be calculated, and the stress condition of the current cable can be calculated and analyzed in real time according to the current breaking condition of the monitoring wires.
F＝F1+F2+F3 (1)
F1/S1E1＝F2/S2E2＝F3/S3E3 (2)
Wherein S 1、S2 and S 3 are the areas of the insulating rubber 110, the monitoring wire 210 and the functional wire 110, and E 1、E2 and E 3 are the elastic moduli of the materials used for the insulating rubber 110, the monitoring wire 210 and the functional wire 110, respectively.
S3＝πB2/4 (3)
S2＝nπd2/4 (4)
S1＝π(A2-B2-nd2)/4 (5)
Further, as a preferred embodiment, the allowable number L of the monitoring wires in the cable wires when broken can be controlled, so that the allowable damage degree of the cable wires is controlled. It can be considered that in an extreme case, only the monitoring lines bear all loads, the number n0 of the required monitoring lines can be calculated according to the mechanics of materials, and the allowable number l=n-n 0 of the monitoring lines at the time of breakage.
The fracture monitoring method designed by the utility model utilizes the monitoring line which is arranged and penetrates through the whole cable line, and a passage is formed between the upper computer and the lower computer. With the long-term friction wear or stress pulling of the cable, the cable is broken from external wear or internal pulling, and after the monitoring line is broken, the passages of the upper computer and the lower computer are cut off. At this time, the upper computer can know the whole fracture condition of the cable conductor.
The fracture monitoring method of the utility model provides a theoretical formula based on composite mechanics. According to the formula, the materials, the positions and the number of the monitoring lines can be reasonably selected, and a fracture threshold value is set.
The fracture monitoring structure designed by the utility model adopts a three-layer structure design, namely an insulating layer, a monitoring layer and a functional layer. The insulating layer and the monitoring layer mainly bear traction force, and meanwhile the monitoring layer also plays a role in monitoring cable breakage. The functional layer does not bear traction force and mainly serves as a functional cable to play a role in power supply or communication.
The foregoing description is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, and it will be appreciated by those skilled in the art that equivalent substitutions and obvious variations may be made using the description and illustrations of the present utility model, and are intended to be included within the scope of the present utility model.
