[0020] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0021] The first implementation method: Figure 1-2 A reinforced aluminum alloy cable is shown.

The intermediate positioning member 4 includes an outer sheath 401, and an inner gasket ring 402 sleeved on the outer side of the core body 1 is installed in the outer sheath 401. The inner gasket ring 402 is provided with multiple guide channels matching the guide holes, and the guide channels are provided with multiple output ports, and the multiple output ports are respectively connected to one guide hole. A plane groove is provided on the outer sheath 401, and an input pipe communicating with the guide channel in the inner gasket ring 402 is installed on the plane groove, and the input end of the guide channel is communicated with the input pipe; When the intermediate positioning member 4 is initially installed, the guide channel is connected to the guide hole. At this time, the protective agent for cable protection can be input into the elastic reinforcement tube 202 through the input pipe and the guide channel on the intermediate positioning member 4; the elastic reinforcement tube 202 can be filled with a part of the protective agent according to actual needs, such as pure water for improving the buffering effect of the elastic reinforcement tube 202 and a flame retardant for improving the flame retardant effect; When the elastic strengthening tube 202 needs to be closed, the middle positioning member 4 is rotated to make the guide hole and the guide channel staggered, so that the elastic strengthening tube 202 can be closed; and then the middle positioning member 4 and the partition ring 201 are fixed by a fixing member, and the fixing member includes a locking screw; Optionally, the inner gasket ring 402 includes a pair of hollow semi-cylinders that are clamped together, and the guide channels in the pair of hollow semi-cylinders are connected after the clamping. A one-way valve matching the guide channel is installed in the guide hole. The one-way valve is installed at the guide hole as a closing component of the elastic reinforced tube 202, so that the intermediate positioning member 4 can remain fixed after installation, and there is no need to rotate to close the output end of the elastic reinforced tube 202. The protective agent is input into the elastic reinforced tube 202 and is closed.

[0022] A temperature monitoring line 3 is passed through the elastic reinforcement tube 202, and a plurality of evenly distributed temperature sensing units are arranged on the temperature monitoring line 3. The two ends of the temperature monitoring line 3 are respectively fixedly connected to two partition rings 201, and an electric socket 203 matching the temperature monitoring line 3 is installed on the partition ring 201; the electric socket 203 is connected to the plurality of temperature monitoring lines 3; The outer end of the segmented reinforcement sleeve 2 is sleeved with multiple auxiliary protection rings 6, and the auxiliary protection ring 6 includes a pair of elastic clamps 601, and multiple pressure detectors 602 are installed in the elastic clamps 601; the upper and lower sides of the pressure detector 602 are respectively installed with an outer probe 603 and an inner probe 604, the outer probe 603 is used to detect external impact force, and the inner probe 604 is used to detect the expansion state of the cable after the protective agent is filled, and a buffer pad is installed on the top of the inner probe 604, and the buffer pad is attached to the insulating protective layer, and an arc buffer plate 605 is installed on the outer probe 603, and the buffer pad and the arc buffer plate 605 are both used for buffering protection of the cable; The elastic clamp ring 601 is provided with a plurality of evenly distributed wire harness grooves, in which a wiring seat 606 matching the pressure detector 602 is installed; the arc-shaped buffer plate 605 covers the arc-shaped area on the surface of the elastic clamp ring 601 between two adjacent wire harness grooves; A reinforcement line 5 is passed through between the plurality of auxiliary protection rings 6 . The reinforcement line 5 includes an inner wire harness 501 . A plurality of wiring heads 502 matching with the wiring base 606 are installed on the inner wire harness 501 .

[0023] Both ends of the inner wiring harness 501 are equipped with anchor connectors matching the power socket 203, and signal lines connected in parallel with multiple wiring heads 502 are installed on the anchor column. The auxiliary protective ring 6 is electrically connected to a wiring head 502 through the wiring socket 606, and the power socket 203 is connected to the signal line through the anchor connector.

[0024] In this embodiment, by providing the segmented reinforcement sleeve 2, the cable maintains overall flexibility while enhancing local compression resistance. The elastic reinforcement tube 202 in the segmented reinforcement sleeve 2 enhances the elastic buffering effect through the elastic support block, which can effectively absorb external impact and reduce the risk of cable damage. In addition, the fillability of the elastic reinforcement tube 202 allows the cable to be added with different protective agents as needed.

[0025] Secondly, the design of the middle positioning member 4 is not only convenient for inputting the protective agent into the elastic reinforcement tube 202, but also can achieve sealing of the elastic reinforcement tube 202 after the protective agent is filled in by means of rotational dislocation, which is easy to operate and has significant effects.

[0026] By introducing the temperature monitoring line 3 and the auxiliary protection ring 6, the cable of this embodiment can monitor the temperature inside the cable and the external impact force in real time, providing an important guarantee for the safe operation of the cable. At the same time, the temperature monitoring line 3 and the auxiliary protection ring 6 can be connected to the external system through the reinforcement line 5, and the monitoring data of the cable can be transmitted to the external system in real time, which is convenient for monitoring and managing the cable status.

[0027] Second implementation method: Figure 7-8 As shown, it also includes a protection monitoring system, which includes a processor, multiple temperature monitoring lines 3 and auxiliary protection rings 6 are electrically connected to the processor through a reinforcement line 5, and the processor is connected to a data processing module, a monitoring module, an alarm module and a communication module. The communication module is used to connect to external equipment, and a high-pressure pump for inputting a protective agent into an input pipe of the intermediate positioning member 4 is connected to the communication module signal; The monitoring module is used to collect cable monitoring data, which includes: temperature monitoring data of the temperature monitoring line 3 and pressure monitoring data of the protection ring 6; The data processing module is used to process the cable monitoring data and determine the cable operation status. When the pressure detection data of the auxiliary protection ring 6 is greater than the set value during the debugging after the cable is laid, the data processing module calculates the amount of protective agent to be filled into the elastic reinforcement tube 202 according to the pressure detection data. The input amount of the protective agent is proportional to the pressure detection value. A technical formula related to the input amount of the protective agent and the pressure detection value is set by a person skilled in the art in the data processing module. The alarm module is used to generate an alarm when the cable operation status is abnormal.

[0028] A method for installing a reinforced aluminum alloy cable comprises: A1, laying cables, laying cables in the preset area; A2, after the cable is laid, multiple auxiliary protection rings 6 are installed on the segmented reinforcement sleeve 2. After the auxiliary protection rings 6 are installed, the multiple auxiliary protection rings 6 are connected to the power socket 203 through the reinforcement line 5 to connect the signal of the external monitoring module. It should be noted that the reinforcement line 5 is set on the side of the cable away from the ground, and only the upper half of the auxiliary protection ring 6 is connected; A3, debugging after cable laying: After the cable is laid, the pressure state of the auxiliary protection ring 6 is detected according to the cable installation environment. When the detection value of the outer probe 603 of the auxiliary protection ring 6 is greater than the set value, the segmented reinforcement sleeve 2 is adjusted; A31, when the segmented reinforcement sleeve 2 is adjusted, the protective agent is input into the elastic reinforcement tube 202 through the intermediate positioning piece 4; when adjusting, the data processing module calculates the input amount of the protective agent according to the pressure detection value, and then connects the high-pressure pump through the communication module, so that the high-pressure pump inputs the protective agent into the input pipe of the intermediate positioning piece 4, and the input amount of the protective agent is proportional to the pressure detection value in A3, and the protective agent includes flame retardant and pure water; A32, when the pressure value detected in the inner probe 604 increases, the high-pressure pump is turned off and the input of the protective agent is stopped; A4, cable fixing, connect and fix the middle positioning piece 4 to the external bracket.

[0029] The cable installation method of this embodiment adopts the configuration of auxiliary protection ring 6 and reinforcement wire 5, which ensures that the external impact force and internal temperature changes can be accurately captured and fed back in real time after the cable is laid. In addition, with the close cooperation between the external monitoring module and the data processing module, the operating status of the cable can be accurately judged and efficiently processed, thereby ensuring that it always maintains the best working state.

[0030] The cable installation technology in this embodiment also places special emphasis on the debugging link after the cable is laid. During the debugging stage, the required protective agent input amount of the elastic reinforcement tube 202 is calculated according to the pressure state information fed back by the auxiliary protection ring 6, so as to make fine adjustments to the segmented reinforcement sleeve 2. During the adjustment, the protective agent is accurately injected into the elastic reinforcement tube 202. While the protective agent is filled to improve the environmental adaptability of the cable, its pressure resistance is also enhanced.

[0031] In addition, this embodiment also introduces a protection monitoring system, which realizes comprehensive, real-time monitoring and efficient data processing of the cable operation status through the connection between the processor and multiple temperature monitoring lines 3 and auxiliary protection rings 6. Once the cable operation status becomes abnormal, the alarm module will immediately trigger the alarm mechanism to remind relevant personnel to respond quickly and handle it properly.

[0032] In summary, this embodiment achieves that the cable maintains flexibility while improving the local compressive resistance through the auxiliary protective ring 6 and the segmented reinforcement sleeve 2. After installation, it is easy to adjust the cable status according to the installation environment, and introduce an external system for real-time monitoring and intelligent management, ensuring the safe and stable operation of the cable.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
