[0002] my country's power industry is currently developing rapidly, and cables are playing an increasingly important role in it. The quality issues of cables during the production process are of particular concern to the power industry. Generally, the poor concentricity of cables during processing is a thorny issue faced by the industry. Due to the manufacturing process, static electricity attached to the conductor, and other factors, the magnetic induction generated by the surroundings can easily lead to inaccurate concentricity calculations of the cable conductor by the eccentricity meter. This in turn causes the conductor and insulation layer of the cable to be out of focus, resulting in different insulation layer thicknesses across the cable cross-section. This can lead to problems such as short circuits in the conductor copper wire, uneven cable working capacitance, and poor cable transmission performance parameters. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0016] In order to solve the above technical problems, this embodiment provides a device for improving the measurement accuracy of the eccentricity meter, such as Figure 1 As shown, it includes a pay-off component 10, an extrusion component 30, a cooling component 50 and a take-up component 60 arranged in sequence along the conveying direction of the pay-off component 10, a detection component 40 for monitoring the concentricity of the cable is arranged between the extrusion component 30 and the cooling component 50, and a guide component 20 is further provided on the side of the extrusion component 30 close to the pay-off component 10. The conductor is connected to the ground wire through the guide component 20. By further providing a guide component 20 on the side of the extrusion component 30 close to the pay-off component 10, the conductor can be grounded through the guide component 20 before entering the detection component 40 to filter out the interference of static electricity and electromagnetic clutter, thereby reducing the measurement fluctuation amplitude of the detection component 40 data, thereby ensuring the accuracy of the detection component 40 in monitoring the concentricity of the cable, filtering out electromagnetic clutter and electrostatic interference in the conductor, and thereby providing the detection accuracy of the detection component 40 to ensure the concentricity of the conductor and the insulation layer of the cable during processing.

[0017] Specifically, the detection component 40 includes an eccentricometer 41 for calculating the concentricity of the cable, and an induction tube 42 arranged on the side of the eccentricometer 41 close to the cooling component 50, and the monitoring end of the induction tube 42 is connected to the eccentricometer 41. By providing the eccentricometer 41 for calculating the concentricity of the cable, the concentricity of the conductor and the insulation layer during the processing can be monitored and ensured through the eccentricometer 41. A induction tube 42 is provided on one side of the eccentricometer 41, and the monitoring end of the induction tube 42 is connected to the eccentricometer 41, so that the outer diameter and thickness data of the cable can be measured through the induction tube 42, and then the data is fed back to the upper computer connected to the eccentricometer 41, so as to cooperate with the eccentricometer 41 to calculate the concentricity of the cable, and the induction tube 42 can also monitor the current size and electromagnetic waveform amplitude in the cable, so that it can detect whether the guide component 20 completely filters out the electromagnetic clutter interference in the conductor, realize the monitoring of the cable processing concentricity, and ensure the accuracy of the concentricity calculation of the eccentricity of the eccentricometer 41.

[0018] In the above scheme, if Figure 2As shown, the guide assembly 20 includes a guide wheel 21, and a wire groove 23 is provided on the circumferential surface of the guide wheel 21. The inner conductor of the cable is connected to the extrusion assembly 30 through the wire groove 23. Several groups of brush holders 22 are detachably provided on the outside of the guide wheel 21. One side of the brush holder 22 abuts against the guide wheel 21, and the other side of the brush holder 22 abuts against the guide wheel 21 and is grounded. For example, the material of the guide wheel 21 and the brush holder 22 can be copper. By providing a wire groove 23 on the circumferential surface of the guide wheel 21, the inner conductor of the cable can be guided and transported to the extrusion assembly 30 through the wire groove 23, and then several groups of brush holders 22 are detachably provided on the outside of the guide wheel 21, one side of the brush holder 22 abuts against the guide wheel 21, and the other side of the brush holder 22 abuts against the guide wheel 21 and is grounded. Therefore, the electromagnetic clutter interference and static electricity in the conductor can be filtered out by grounding the brush holder 22, thereby improving the accuracy of the concentricity calculation of the heart 41 and filtering out the electromagnetic clutter interference in the conductor.

[0019] Furthermore, the guide assembly 20 also includes a mounting shaft 24, and the guide wheel 21 is rotatably mounted on the mounting shaft 24. A mounting bracket 25 is also provided on the mounting shaft 24 on the side of the guide wheel 21, and the brush holder 22 is detachably mounted on the mounting bracket 25 through fasteners. By providing a mounting bracket 25 on the mounting shaft 24 on the side of the guide wheel 21, the brush holder 22 is detachably mounted on the mounting bracket 25 through fasteners, so that the brush holder 22 can adjust the installation distance from the guide wheel 21 through the mounting bracket 25, and then cooperate with one side of the brush holder 22 to abut against the guide wheel 21, so that the electromagnetic clutter and static electricity in the conductor are filtered out by grounding the brush holder 22, and then the brush holder 22 is detachably mounted on the mounting bracket 25 by setting fasteners, so that the subsequent replacement and maintenance of the brush holder 22 equipment is convenient, and the guide transmission cable is achieved in cooperation with the guide wheel 21.

[0020] In order to ensure that the brush holder 22 is in close contact with the guide wheel 21, as a preferred embodiment, an elastic member is provided in the brush holder 22 to ensure that the brush holder 22 is in close contact with the guide wheel 21. By providing the elastic member in the brush holder 22, the brush holder 22 can be in close contact with the guide wheel 21, thereby ensuring that the electromagnetic noise and static electricity in the conductor can be completely filtered out through the grounding of the brush holder 22, thereby achieving the contact of the brush holder 22 with the guide wheel 21.

[0021] Specifically, the cooling component 50 can be a cooling water trough. By providing the cooling component 50, for example, the cooling component 50 can be a cooling water trough, so that during the extrusion process, the surface temperature of the cable can be cooled by the cooling water trough, thereby avoiding high-temperature deformation of the cable during the extrusion process.

[0022] To sum up, in one or more embodiments of the present application, the present application arranges an extrusion assembly, a cooling assembly and a take-up assembly in sequence in the pay-off assembly and along the conveying direction of the pay-off assembly, and arranges a detection assembly for monitoring the concentricity of the cable between the extrusion assembly and the cooling assembly. A guide assembly is also arranged on the side of the extrusion assembly close to the pay-off assembly, and the conductor is connected to the ground wire through the guide assembly. By further arranging a guide assembly on the side of the extrusion assembly close to the pay-off assembly, the conductor can be grounded through the guide assembly to filter out electromagnetic interference before entering the detection assembly, thereby reducing the measurement fluctuation amplitude of the detection assembly data, thereby ensuring the accuracy of the detection assembly in monitoring the concentricity of the cable, and filtering out electromagnetic interference in the conductor, thereby ensuring the concentricity of the conductor and the insulation layer of the cable during processing.
