Description

Technical Field

[0001] The present invention relates to the technical field of cable monitoring and correction, and in particular to a cable with internal monitoring and correction mechanisms. Background Art

[0002] A cable is a carrier used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. It consists of one or more insulated wire cores, a covering layer, a protective layer, and an outer protective layer. During use, a cable will be subjected to mechanical stresses under different conditions, and problems such as fatigue damage are likely to occur after long-term use, directly affecting the service life of the cable. Therefore, it is necessary to monitor the state of the cable so as to immediately correct the attitude of the cable. Traditional cables simply judge the cable state by the tension at the connection end. This monitoring method not only has limited effects, but also has relatively poor monitoring accuracy, and cannot correct the attitude of the cable. At the same time, the loading and unloading are also relatively troublesome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that traditional cables simply judge the cable state by the tension at the connection end. This monitoring method not only has limited effects, but also has relatively poor monitoring accuracy, and cannot correct the attitude of the cable. At the same time, the loading and unloading are also relatively troublesome.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a cable with internal monitoring and correction mechanisms, including an internal core wire. A core wire shield is arranged outside the internal core wire. A core wire insulation is sleeved outside the core wire shield. An insulation shield is sleeved outside the core wire insulation. A water blocking layer is sleeved outside the insulation shield. A PE sheath is sleeved outside the water blocking layer. An inner sheath, an armor, and an outer sheath are sequentially arranged outside the PE sheath. A filling layer is arranged between the inner sheath and the PE sheath. A plurality of internal monitoring and correction modules arranged in a circular matrix are arranged inside the filling layer.

[0005] The internal monitoring and correction module includes an inner adjusting cylinder body fixed inside the filling layer, lateral piston rods slidably installed at both ends of the inner adjusting cylinder body, lateral compression springs for controlling the telescopic movement of the lateral piston rods, flexible pull ropes installed at the outer ends of the lateral piston rods, and an inner monitoring module.

[0006] Circular internal detection seats for installing the inner monitoring module are provided on the inner walls on both sides of the inner adjusting cylinder body.

[0007] The inner monitoring module includes a circular pressure sensor module fixedly installed on the circular internal detection seat, a circular temperature sensor module fixedly installed on the outer side surface of one end of the inner adjusting cylinder body, and a circular humidity sensor module fixedly installed on the outer side surface of the other end of the inner adjusting cylinder body.

[0008] On one end face of the lateral piston rod close to the side of the lateral compression spring, an annular extrusion groove is provided. One end of the lateral compression spring is inserted into the annular extrusion groove and connected to the lateral piston rod, and the other end of the lateral compression spring is sleeved outside the annular internal detection seat and connected to the inner adjustment cylinder block.

[0009] On the outer side face of the inner adjustment cylinder block, there is an externally protruding external limit ring of an integral structure.

[0010] On the outer side face of the external limit ring, a lateral flipping groove is provided. Inside the lateral flipping groove, a flipping type connecting sleeve is movably assembled, and inside the flipping type connecting sleeve, a communication cable for transmitting monitoring signals is installed.

[0011] On the outer side end of the lateral piston rod, an end telescopic blind hole for connecting a flexible pull rope is provided. At the outer opening position of the end telescopic blind hole, an internal thread mounting groove is provided, and an internal adjustment block is fixed at the end of the flexible pull rope.

[0012] Inside the internal thread mounting groove, an external thread limit ring for restricting the internal adjustment block is threadedly assembled.

[0013] On the outer side face of the inner adjustment cylinder block, the inner side of the inner adjustment cylinder block, and the connecting surface of the outer side of the lateral piston rod, arc-shaped transition grooves are all provided.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) By arranging internal monitoring and correction modules in a ring matrix arrangement inside the filling layer, the cable with an internal monitoring and correction mechanism of the present invention can monitor the posture of the cable from multiple directions, greatly improving the monitoring range of the cable and making the monitoring data more comprehensive;

[0016] (2) The entire internal monitoring and correction module can not only monitor the bending degree and stretching deformation length of the cable through the flexible pull ropes at both ends, but also measure the temperature and humidity conditions inside the cable, greatly improving the comprehensiveness of the monitoring data;

[0017] (3) There is an externally protruding external limit ring of an integral structure on the outer side face of the inner adjustment cylinder block, which can improve the installation stability and anti-displacement effect of the entire monitoring and correction device;

[0018] (4) Through the external limit ring, not only can the assembly limiting ability be improved, but also the communication cable can be connected and assembled, thus greatly reducing the damage to the connection end caused by the bending of the cable, and improving the signal transmission performance and facilitating assembly;

[0019] (5) The internal monitoring and correction module adopts a detachable structure design, which can be quickly separated from the flexible pull rope and the communication cable, facilitating loading and unloading and reducing costs;

[0020] (6) By adopting a combined rigid and flexible structure design, it is not affected by the bending of the cable, greatly improving the monitoring accuracy and durability;

[0021] (7) The entire internal monitoring and correction module can not only be elastically reset through the internal lateral extrusion spring, but also correct the posture of the cable, thereby improving the internal tension of the cable and enhancing functionality and practicality.

[0026] The present invention will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Figure 1 、 Figure 2 and Figure 3 As shown in, a cable with an internal monitoring and correction mechanism includes an internal core wire 1, a core wire shield 2 is arranged outside the internal core wire 1, a core wire insulation 3 is sleeved outside the core wire shield 2, an insulation shield 4 is sleeved outside the core wire insulation 3, a water blocking layer 5 is sleeved outside the insulation shield 4, a PE sheath 6 is sleeved outside the water blocking layer 5, an inner sheath 7, an armor 8 and an outer sheath 9 are sequentially arranged outside the PE sheath 6, a filling layer 10 is arranged between the inner sheath 7 and the PE sheath 6, and a plurality of internal monitoring and correction modules arranged in a circular matrix are arranged inside the filling layer 10.

[0029] To cooperate with telescoping and elastic extrusion reset, the internal monitoring and correction module includes an inner adjustment cylinder body 11 fixed inside the filling layer 10, lateral piston rods 12 slidably installed at both ends of the inner adjustment cylinder body 11, a lateral extrusion spring 13 for controlling the telescoping of the lateral piston rods 12, a flexible pull rope 14 installed at the outer ends of the lateral piston rods 12, and an inner monitoring module 15.

[0030] The lateral piston rod 12 consists of an internal slider slidably assembled with the inner adjustment cylinder body 11 and a sliding connecting rod fixed on the side wall of the internal slider. The lateral extrusion spring 13 presses the internal slider inward to control the internal slider to slide towards the middle of the inner adjustment cylinder body 11, and the outer end of the sliding connecting rod is connected to the flexible pull rope 14. Both ends of the flexible pull rope 14 are installed with the inner monitoring module 15, so as to ensure the monitoring of different positions of the cable.

[0031] When there is leakage due to damage to the outer sheath of the cable, the leaked liquid can be introduced to the position of the inner monitoring module 15 through the flexible pull rope 14, thereby expanding the monitoring range.

[0032] To improve the assembly stability, annular internal detection seats 16 for installing the inner monitoring module 15 are provided on the inner walls on both sides of the inner adjustment cylinder body 11.

[0034] The magnitude of the force is monitored by the lateral extrusion spring 13 pressing on the annular pressure sensor module 151. The acting force on the outer periphery of the bending section is larger, while the acting force on the inner side of the bending section becomes smaller.

[0035] When the cable bends, the forces exerted by the flexible pull ropes 14 in different directions are inconsistent. By the magnitude of the acting force of the annular pressure sensor module 151, it can be judged which section is bent, the direction of the bend, the amplitude of the bend, and whether the cable section needs to be corrected; if the forces monitored by all the annular pressure sensor modules 151 in this section gradually become smaller, it indicates that this section of the cable has undergone tensile deformation.

[0036] To cooperate with elastic extrusion assembly, an annular extrusion groove is provided on the end face of the lateral piston rod 12 close to the lateral extrusion spring 13. One end of the lateral extrusion spring 13 is inserted into the annular extrusion groove and connected to the lateral piston rod 12, and the other end of the lateral extrusion spring 13 is sleeved outside the annular internal detection seat 16 and connected to the inner adjustment cylinder body 11.

A communication cable 18 for transmitting monitoring signals is installed inside the flipping type connecting sleeve 172.

[0039] Both ends of the flipping type connecting sleeve 172 are provided with mounting holes for connecting the communication cable 18, which are used to connect the communication cables on both sides in series, and at the same time, it is also convenient to electrically connect the communication cable 18 at the inner end to the annular pressure sensor module 151, the annular temperature sensor module 152, and the annular humidity sensor module 153 respectively.

[0040] To cooperate with the lateral piston rod 12, an end telescopic blind hole 121 for connecting the flexible pull rope 14 is formed at the outer end of the lateral piston rod 12. An internal thread mounting groove is formed at the opening position of the outer side of the end telescopic blind hole 121, and an internal adjustment block 141 is fixed at the end of the flexible pull rope 14.

[0041] To cooperate with the outer limit, an external thread limit ring 122 for restricting the internal adjustment block 141 is threadedly assembled inside the internal thread mounting groove.

[0042] The external thread limit ring 122 is threadedly assembled inside the internal thread mounting groove to perform assembly limit on the internal adjustment block 141.

[0043] To cooperate with the transition, facilitate the connection of signal connection lines, and at the same time improve the lateral stability of the inner adjustment cylinder block 11, arc-shaped transition grooves 19 are formed on the outer side surface of the inner adjustment cylinder block 11, the inner side of the inner adjustment cylinder block 11, and the connecting surface of the outer side of the lateral piston rod 12.
