[0001] The present invention relates to the technical field of cables, in particular to the technical field of intelligent temperature-controlled composite cables. [Background technology]

[0002] With large-scale urban development and construction, cables are used more and more widely. With the long-term use of cables and high-temperature environment, the temperature of cables can continue to rise, causing local overheating and burning of cables. In severe cases, fire or explosion may occur, causing a large amount of economic losses. In order to prevent major losses caused by excessive cable temperature, it is necessary to detect and control the temperature of the cable in real time. Cable temperature detection is generally carried out by manual handheld detection. Manual detection has high labor intensity and detection error, low detection efficiency, and cannot meet the detection needs. [Summary of the invention]

[0004] To achieve the above-mentioned purpose, the present invention proposes an intelligent temperature-controlled composite cable, comprising a central cross skeleton, an aluminum foil set, a conductive core, an insulating inner sheath, a tensile mesh layer, a heat-conducting exoskeleton layer, a heat-conducting liquid cooling tube, a micro-circulation pump, a temperature sensor, an aluminum-plastic composite layer, a heat-insulating fire-resistant sheath and a wear-resistant outer sheath, wherein the outer side of the central cross skeleton is evenly coated with an aluminum foil set, a plurality of conductive cores coated with insulating sheaths are sandwiched on the outer side of the central cross skeleton, an insulating inner sheath is sleeved on the outer side of the central cross skeleton, and the outer side of the insulating inner sheath is A tensile mesh layer is tightly sleeved on the side, and a heat-conducting exoskeleton layer is coated on the outer side of the tensile mesh layer. A plurality of heat-conducting liquid cooling pipes are axially inserted in the heat-conducting exoskeleton layer, and micro-circulation pumps are connected to both ends of the heat-conducting liquid cooling pipes. A plurality of temperature sensors are evenly arranged in the heat-conducting exoskeleton layer, and the temperature sensors are connected to the micro-circulation pumps. The outer side of the heat-conducting exoskeleton layer is coated with an aluminum-plastic composite layer, and the outer side of the aluminum-plastic composite layer is sleeved with a heat-insulating and fire-resistant jacket, and the outer side of the heat-insulating and fire-resistant jacket is sleeved with a wear-resistant outer jacket.

[0005] Preferably, an arc-shaped heat-conducting sheet is provided at the outer end of the aluminum foil sleeve, and the outer side surface of the arc-shaped heat-conducting sheet is in contact with the insulating inner sheath.

[0006] Preferably, a tensile harness is interspersed along the axis of the center of the central cross frame, and the tensile harness is a multi-strand twisted nylon harness.

[0007] Preferably, the heat-conducting exoskeleton layer is a hollow heat-conducting plastic skeleton layer, and a plurality of heat-conducting support bars are evenly arranged around the heat-conducting exoskeleton layer. The heat-conducting support bars are penetrated by pipe through grooves, and the heat-conducting liquid cooling pipes are inserted in the pipe through grooves. The temperature sensor is fixedly arranged on the outside of the heat-conducting support bars.

[0008] Preferably, the inner side surface of the thermally conductive exoskeleton layer is a smooth arc surface, the thermally conductive exoskeleton layer is tightly fitted on the outer side surface of the anti-tensile mesh layer, the anti-tensile mesh layer is a high thermal conductive mesh layer, and the anti-tensile mesh layer is adhered to the outer side surface of the insulating inner sheath.

[0009] Preferably, the aluminum-plastic composite layer is a thermochromic high-temperature-resistant aluminum-plastic composite film layer, and the aluminum-plastic composite layer is wrapped around the outer side of the heat-conducting exoskeleton layer.

[0010] Preferably, the temperature sensor has a built-in GPS positioning module and a wireless transmission module, the micro-circulation pump has an external power supply module and a touch display hub, the temperature sensor is connected to the power supply module and the touch display hub respectively, and the micro-circulation pump is internally connected to an external cooling liquid tank.

[0011] Beneficial effects of the present invention: The present invention combines a central cross skeleton, an aluminum foil set, a conductive wire core, an insulating inner sheath, a tensile mesh layer, a heat-conducting exoskeleton layer, a heat-conducting liquid cooling tube, a micro-circulation pump, a temperature sensor, an aluminum-plastic composite layer, a heat-insulating fire-resistant sheath and a wear-resistant outer sheath together. After experimental optimization, the central cross skeleton with an aluminum foil set coated on the outer side cooperates with the tensile wire harness to effectively improve the tensile and bending resistance of the wire core of the cable. At the same time, the heat generated by the conductive wire core is quickly thermally conductive through the large-area contact between the aluminum foil set and the insulating inner sheath. The insulating inner sheath, the tensile mesh layer and the heat-conducting exoskeleton layer cooperate with each other to effectively improve the tensile and bending resistance of the middle part of the cable. At the same time, a stable heat dissipation space is formed, which is beneficial to the setting of the heat dissipation structure. The liquid cooling pipe, temperature sensor and micro-circulation pump cooperate with each other. When the temperature sensor senses that the temperature of the heat-conducting exoskeleton layer is too high and reaches the threshold, the micro-circulation pump automatically supplies coolant to the heat-conducting liquid cooling pipe for continuous water cooling until the temperature sensor senses that the temperature of the heat-conducting exoskeleton layer drops below the threshold. The micro-circulation pump stops working. The thermochromic high-temperature aluminum-plastic composite film is used as the outer aluminum-plastic composite layer. During cable maintenance, the high-temperature part of the cable can be quickly identified through the color change effect of the aluminum-plastic composite layer, thereby improving the maintenance efficiency. The heat-insulating and fire-resistant sheath is combined with the wear-resistant outer sheath to effectively prevent the influence of the external high-temperature environment on the internal structure of the cable, thereby improving the stability of cable use, and automatically performing cable detection and cooling operations. The detection efficiency is high, which fully meets the cable temperature control detection needs.
