Description

Technical Field

[0001] This invention relates to the field of intelligent power cable technology, specifically to an intelligent power cable suitable for complex environments and a method for manufacturing its protection. Background Technology

[0002] As an important carrier of electrical energy transmission, power cables are widely used in power grid transmission and distribution, power equipment connection and power supply systems in complex environments. With the development of smart grids and the energy internet, power cables are gradually evolving towards intelligence. In addition to undertaking the basic function of power transmission, they also need to have the capabilities of status monitoring, fault early warning and information interaction. However, when existing power cables are used in complex environments (such as humidity, high temperature, mechanical impact, and overhead laying), they are easily affected by external factors, which can lead to scratches, damage, or even cracks in the outer sheath. Once damage occurs, it is usually discovered through manual inspection or periodic testing, which has the defects of untimely detection and delayed response, thus affecting the safety and reliability of cable operation.

[0003] In addition, most existing cables adopt passive protection structures, which lack the ability to actively respond to damage and cannot quickly self-repair after damage occurs. At the same time, in long-distance overhead or complex installation environments, the cable is subjected to concentrated stress and large swing, which can easily cause mechanical fatigue and structural damage, further reducing its service life.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. An adaptive pressure-triggered self-repair component is set up. Through the cooperation between the various components within the adaptive pressure-triggered self-repair component, the use, inspection, and repair process of smart power cables is optimized. The pressure changes inside the smart power cable are used to adjust the liquid flow direction inside the flexible liquid storage chamber and the repair agent storage chamber. The properties of the moisture-curing polyurethane cable repair adhesive inside the repair agent storage chamber are utilized to quickly repair the damage to the smart power cable when it is scratched or damaged. The pressure inside the smart power cable is detected in real time by a hydraulic sensor to ensure that the damage to the smart power cable can be repaired quickly. At the same time, it allows maintenance personnel to detect and repair the damage in a timely manner, thereby effectively improving the convenience and safety of smart power cable maintenance. Simultaneously, the flexible liquid storage chamber and the internal insulating heat-conducting oil of the liquid-conducting capillary tube assist the intelligent power cable in heat conduction and dissipation, ensuring that the intelligent power cable can continuously maintain a suitable temperature range during use. At the same time, the splicing structure of the components inside the connection installation box and the repair agent storage chamber allows maintenance personnel to quickly replace the repair agent storage chamber during the maintenance of the intelligent power cable, ensuring that the moisture-curing polyurethane cable repair adhesive maintains good performance throughout the use of the intelligent power cable, further improving the overall convenience of maintenance and use of the intelligent power cable.

[0015] 2. An external lifting and adjusting support mechanism is set up. Through the cooperation between the various components inside the external lifting and adjusting support mechanism, the installation and adjustment process of the smart power cable is optimized. The smart power cable is assisted in pulling by the snap-fit ​​base, snap-fit ​​top seat and mounting rectangular plate, which effectively improves the overall stress of the smart power cable. It prevents the weight of the cable from being entirely applied to the connection points at both ends of the cable when the smart power cable is connected over a long distance, thereby improving the stability and reliability of the smart power cable installation. Furthermore, the elastic rubber connecting column provides additional buffering characteristics for the swinging smart power cable by utilizing its expansion and contraction characteristics, further improving the safety and stability of the smart power cable in use. Meanwhile, the height of the intelligent power cable can be adjusted by a dual-head adjustable motor and a winding disc, further improving the stress distribution on the intelligent power cable. This makes the overall stress distribution more uniform when the intelligent power cable is installed overhead. By changing the height of the intelligent power cable, the indirection between the bottom diameter and the bottom surface diameter is altered, effectively preventing the intelligent power cable from rubbing against moving equipment at its bottom during use and thus improving the safety and ease of height adjustment of the intelligent power cable.

[0016] In summary, by coordinating the adaptive pressure-triggered self-healing component and the various components within the external lifting and adjusting support mechanism, the usage detection and adjustment process of the intelligent power cable is optimized. The stress distribution on the intelligent power cable is improved by connecting the various components on the mounting rectangular plate and the mounting side plate, making the overall adjustment process more convenient and effectively enhancing the safety of the intelligent power cable. Furthermore, by detecting the internal pressure of the intelligent power cable and monitoring its changes, the system proactively monitors the cable's usage in real time and actively repairs it after damage, effectively improving both the safety and convenience of using the intelligent power cable.

[0021] like Figure 11 As shown, a method for manufacturing intelligent power cable protection suitable for complex environments includes the following steps: S1. Internal molding: The external structure of the internal conductor 1 is independently processed and molded by winding equipment and extrusion equipment, and the rubber filler strip 5 is wrapped around the outside of the internal signal transmission line 6 to complete the production of the internal components of the cable. S2. Internal assembly: Then, the internal conductor 1 and rubber filler strip 5 are filled to the outside of the internal support isolation bracket 4 through the corresponding assembly equipment, and then the internal components of the cable are assembled and formed through the corresponding production equipment. S3. External molding: Then, the splicing rubber sleeve 901 is extruded and wrapped onto the outside of the outer rubber protective layer 8 using the corresponding equipment to complete the rapid molding of the cable's external structure. S4. External assembly: The liquid-conducting capillary 906 is arranged on the outside of the splicing rubber sleeve 901 using appropriate assembly equipment, and the braided protective layer 902 and the external rubber isolation layer 903 are wrapped on the outside of the liquid-conducting capillary 906 using appropriate equipment to complete the external structure forming of the cable. S5. Debugging and Testing: The installers install the hardened arc box 904, the snap-fit ​​base 1001, and the snap-fit ​​top seat 1002, along with the components connected to them, onto the outside of the cable. After the cable assembly is completed, the parameters are tested to complete the installation and connection of each component of the cable.

[0022] The working principle and usage process of this invention: In the actual application of this invention, during the production of intelligent power cables, the inner insulation barrier layer 2 is first wrapped around the outside of the inner conductor 1 by a winding device, and then the inner insulation rubber layer 3 is wrapped around the outside of the inner conductor 1 by an extrusion device. Next, the inner conductor 1 is spliced ​​to the outside of the inner support isolation bracket 4 by an assembly device, and the rubber filler strip 5 and the internal signal transmission line 6 are arranged in sequence at the side gap of the inner support isolation bracket 4. Then, the outer insulation barrier layer 7 is wrapped around the outside of the rubber filler strip 5 by a winding device to bundle and tighten the various structures spliced ​​on the outside of the inner support isolation bracket 4. Finally, the outer rubber protective layer 8 is wrapped around the outside of the outer insulation barrier layer 7 by an extrusion device to complete the production of the inner body of the intelligent power cable. When it is necessary to assemble the various structures on the outside of the smart power cable, the splicing rubber sleeve 901 is wrapped around the outside of the outer rubber protective layer 8 by the extrusion equipment, so that the liquid guiding capillary 906 is arranged on the outside of the splicing rubber sleeve 901. The braided protective layer 902 and the outer rubber isolation layer 903 are wrapped around the outside of the liquid guiding capillary 906 by the winding equipment and the extrusion equipment, so as to realize the installation of the various components on the outside of the cable. When a smart power cable is needed, the internal conductor 1 should be connected to a suitable position first, and the internal signal transmission line 6 should be connected to the corresponding receiving device. Then, according to the installation position of the hardened arc box 904, the corresponding end of the liquid guiding capillary 906 should be cut off and one end of it should be connected to the flexible liquid storage chamber 905. Then, the other end of the corresponding liquid guiding capillary 906 should be connected to the one-way liquid guiding valve 907. Then, the repair agent storage chamber 913 should be connected to the bottom of the liquid guiding connecting pipe 908 through the connecting round box 909 to complete the initial assembly of the external structure of the smart power cable. Next, using an external liquid storage device, insulating heat-conducting oil is injected into the flexible liquid storage chamber 905 and the liquid-conducting capillary 906 through a one-way liquid-conducting valve 907. The hydraulic pressure inside the liquid-conducting capillary 906 is monitored in real time by a hydraulic sensor 912 inside the liquid-conducting connecting pipe 908 to ensure that the pressure in the top area of ​​the repair agent storage chamber 913 remains within a suitable range. Then, by torturing the adjusting bolt 914, the telescopic base plate 915, the energy storage spring 916, and the telescopic top plate 917 are synchronously raised along the inner wall of the repair agent storage chamber 913 to achieve… Energy storage is achieved in the repair agent storage chamber 913 to ensure that the pressure of the moisture-curing polyurethane cable repair adhesive inside the repair agent storage chamber 913 is always kept within a suitable range. Then, the bottom of the connection mounting box 910 is sealed by the sealing bottom cover 911 to achieve external protection of the repair agent storage chamber 913. At the same time, the connection mounting box 910 is fixed to the side of a suitable mounting bracket by the mounting side plate 923, and the bottom of the hardened mounting arc box 904 is further supported by the support sleeve 922 to realize the intelligent power cable connection installation. When the intelligent power cable is cut externally, causing damage to the liquid-conducting capillary 906, the insulating heat-conducting oil inside the liquid-conducting capillary 906 leaks, causing a decrease in pressure on the upper layer of the limiting isolation plate 920. Under the pressure of the moisture-curing polyurethane cable repair adhesive below it, the isolation elastic plate 919 expands upward. When the limiting isolation plate 920 is broken by the expansion of the isolation elastic plate 919, the top piercing plate 921 pierces the top of the isolation elastic plate 919, causing the moisture-curing polyurethane cable repair adhesive inside the repair agent storage cavity 913 to overflow into the flexible liquid storage cavity 905 and the liquid-conducting capillary 906. After the overflowed moisture-curing polyurethane cable repair adhesive spills out from the cut and comes into contact with air, the isocyanate end groups inside the moisture-curing polyurethane cable repair adhesive react with the moisture in the air to generate polyurethane elastomer, thus repairing the cut and damaged part of the intelligent power cable. The hydraulic sensor 912 monitors sudden changes in values ​​to provide early warning of damage to the intelligent power cable, so that personnel can react quickly and perform manual repairs. When auxiliary support and adjustment of the smart power cable are required, the snap-fit ​​base 1001 and snap-fit ​​top seat 1002 are snapped to the outside of the outer rubber isolation layer 903 by bolts. Then, the splicing connecting cable 1004 is connected to the snap-fit ​​top seat 1002 by connecting bolts 1003. The mounting rectangular plate 1008 is installed in the appropriate position by bolts to fix the mounting round hole 1010. The top of the mounting rectangular plate 1008 is isolated by the limiting silicone ring 1009 to make the mounting rectangular plate 1008 more stable. When the height of the smart power cable needs to be adjusted, the double-headed adjusting motor 1011 drives the winding disc 1012 to rotate. During the rotation of the winding disc 1012, the traction adjusting cable 1007 is wound up. The winding of the traction adjusting cable 1007 drives the splicing connecting cable 1004 and the elastic rubber connecting post 1005 to rise synchronously. The rise of the splicing connecting cable 1004 achieves the height adjustment of the smart power cable. When the cable body sways, the elastic rubber connecting post 1005 is used to buffer and consume the kinetic energy of the smart power cable during the swaying process, thereby effectively improving the stress condition of the smart power cable and further improving the safety of the smart power cable.
