Technical Field

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

[0002] Cable is a carrier used to transmit electrical energy, information and realize electromagnetic energy conversion. It consists of one or more insulating cores, a coating, a protective layer and an outer sheath. During use, the cable will be subjected to mechanical stress in different situations. Long-term use is prone to fatigue damage and other problems, which directly affects the service life of the cable. Therefore, it is necessary to monitor the status of the cable so that the cable posture can be corrected in real time. Traditional cables simply judge the cable status by the tension at the connection end. This monitoring method is not only limited in effect, but also has poor monitoring accuracy. It is also impossible to correct the cable posture, and loading and unloading is also more troublesome. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the traditional cable simply judges the cable status by the pulling force at the connection end. This monitoring method not only has limited effect, but also has poor monitoring accuracy, and cannot correct the cable posture. At the same time, loading and unloading is also troublesome.

[0008] An annular extrusion groove is provided on the end surface of the lateral piston rod close to the lateral extrusion spring. One end of the lateral extrusion spring is inserted into the annular extrusion groove and connected to the lateral piston rod. The other end of the lateral extrusion spring is sleeved on the outside of the annular internal detection seat and connected to the inner adjusting cylinder body.

[0009] The outer side surface of the inner regulating cylinder body is provided with an outer limiting ring of an integral structure protruding outward.

[0010] A lateral flip groove is provided on the outer side surface of the external limit ring, a flip connection sleeve is movably mounted inside the lateral flip groove, and a communication cable for transmitting monitoring signals is installed inside the flip connection sleeve.

[0011] The outer end of the lateral piston rod is provided with an end telescopic blind hole for connecting the flexible pull rope, the outer opening position of the end telescopic blind hole is provided with an internal thread installation groove, and the end of the flexible pull rope is fixed with an internal adjustment block.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3 A cable with an internal monitoring and correction mechanism is shown, comprising an internal core wire 1, a core wire shield 2 is arranged on the outside of the internal core wire 1, a core wire insulation 3 is sheathed on the outside of the core wire shield 2, an insulation shield 4 is sheathed on the outside of the core wire insulation 3, a water-blocking layer 5 is sheathed on the outside of the insulation shield 4, a PE sheath 6 is sheathed on the outside of the water-blocking layer 5, an inner sheath 7, an armor 8 and an outer sheath 9 are arranged in sequence on the outside of 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 ring matrix are arranged inside the filling layer 10.

[0022] In order to cooperate with the telescopic and elastic extrusion reset, the internal monitoring correction module includes an inner adjusting cylinder 11 fixed inside the filling layer 10, a lateral piston rod 12 slidably installed at both ends of the inner adjusting cylinder 11, a lateral extrusion spring 13 for controlling the telescopic movement of the lateral piston rod 12, a flexible pull rope 14 installed at the outer end of the lateral piston rod 12, and an inner monitoring module 15.

[0023] The lateral piston rod 12 is composed of an internal slider slidably assembled with the inner adjusting cylinder 11 and a sliding connecting rod fixed on the side wall of the internal slider. The lateral extrusion spring 13 squeezes the internal slider inward to control the internal slider to slide toward the middle of the inner adjusting cylinder 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 inner monitoring modules 15 to ensure monitoring of different positions of the cable.

[0024] The flexible pull rope 14 can also be used to guide the leaked liquid to the inner monitoring module 15 when the outer sheath of the cable is damaged and leaks occur, thereby increasing the monitoring range.

[0025] In order to improve assembly stability, both inner walls of the inner regulating cylinder 11 are provided with an annular inner detection seat 16 for mounting the inner monitoring module 15 .

[0026] In order to cooperate with the monitoring of internal force, temperature and humidity, the inner monitoring module 15 includes an annular pressure sensor module 151 fixedly mounted on the annular internal detection seat 16, an annular temperature sensor module 152 fixed on the outer surface of one end of the inner adjusting cylinder 11, and an annular humidity sensor module 153 fixed on the outer surface of the other end of the inner adjusting cylinder 11.

[0027] The force is monitored by squeezing the annular pressure sensor module 151 with the lateral squeezing spring 13. The force at the periphery of the bending section is larger, while the force at the inner side of the bending section becomes smaller.

[0028] When the cable bends, the forces applied by the flexible pull rope 14 in different directions are inconsistent. The magnitude of the force applied by the annular pressure sensor module 151 can be used to determine which section is bent, the direction of the bending angle, the magnitude of the bending, and whether the section of the cable needs to be corrected. If the forces detected by all the annular pressure sensor modules 151 in this section gradually decrease, it means that the section of the cable has been stretched and deformed.

[0029] In order to cooperate with the elastic extrusion assembly, an annular extrusion groove is opened 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. The other end of the lateral extrusion spring 13 is sleeved on the outside of the annular internal detection seat 16 and connected to the inner adjusting cylinder 11.

[0030] In order to cooperate with the outer limiting function, the outer side surface of the inner adjusting cylinder body 11 is provided with an outer limiting ring 17 of an integral structure protruding outward.

[0031] In order to cooperate with lateral assembly, a lateral flip groove 171 is opened on the outer side of the external limit ring 17, and a flip connection sleeve 172 is movably assembled inside the lateral flip groove 171, and a communication cable 18 for transmitting monitoring signals is installed inside the flip connection sleeve 172.

[0032] Both ends of the flip-type connecting sleeve 172 are provided with mounting holes for connecting the communication cables 18, which are used to connect the communication cables on both sides in series. It is also convenient to use the communication cable 18 at the inner end to electrically connect with the annular pressure sensor module 151, the annular temperature sensor module 152 and the annular humidity sensor module 153 respectively.

[0033] In order to cooperate with the outer end of the lateral piston rod 12, an end telescopic blind hole 121 for connecting the flexible pull rope 14 is opened, an internal thread installation groove is opened at the outer opening position of the end telescopic blind hole 121, and an internal adjustment block 141 is fixed to the end of the flexible pull rope 14.

[0034] In order to cooperate with the outer limiting, the inner thread of the inner thread installation groove is equipped with an outer thread limiting ring 122 that limits the inner adjustment block 141.

[0035] The external thread limiting ring 122 is threadably assembled in the internal thread installation groove to limit the internal adjustment block 141 .

[0036] In order to facilitate the transition and connect the signal lines conveniently while also improving the lateral stability of the inner adjusting cylinder 11 , arc-shaped transition grooves 19 are provided on the outer side surface of the inner adjusting cylinder 11 , the inner side of the inner adjusting cylinder 11 and the outer connecting surface of the lateral piston rod 12 .

[0037] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
