Description

Technical Field

[0001] This invention relates to a reinforced aluminum alloy cable, and more particularly to a reinforced aluminum alloy cable for use in the field of cables. Background Technology

[0002] Aluminum alloy cables, as an advanced cable material, have been widely used in various fields such as construction, industry, and transportation in recent years. With their unique advantages, aluminum alloy cables have gradually replaced traditional copper cables and steel-cored aluminum stranded wires, becoming the ideal choice for modern power transmission and distribution systems.

[0003] The main advantages of aluminum alloy cables are their excellent conductivity and lighter weight. Compared to copper cables, aluminum alloy cables have slightly lower conductivity, but their weight is significantly reduced. This allows for a substantial reduction in installation and transportation costs when wiring long distances and large buildings.

[0004] To address the issue of low strength in aluminum alloy cables, a certain aluminum alloy cable on the market employs an external multi-layer protective layer design, which has a certain market share.

[0005] Chinese invention patent CN117457272B discloses a fireproof aluminum alloy cable, including a sheath layer; multiple fixed brackets and multiple connectors are provided outside the sheath layer; the connectors are generally circular, and multiple connectors are evenly fitted onto the sheath layer; fixed brackets are evenly fixed between adjacent connectors; the expansion body includes an outer heat-conducting sheet, an inner heat-insulating sheet, a side telescopic body, a compression spring, and a filling cavity; the side telescopic body is generally a hollow cuboid with openings at both ends, and the two openings of the side telescopic body are respectively fitted onto the side walls of the outer heat-conducting sheet and the inner heat-insulating sheet; one end of the outer heat-conducting sheet along a clockwise arc direction is hinged to the end of the corresponding fixed bracket away from the sheath layer; the technical effect is to achieve a low probability of the outer heat-conducting sheet of the cable popping out after the cable is hit, and a low probability of the fire extinguishing agent in the filling cavity inside the heat-conducting sheet leaking.

[0006] Existing aluminum alloy cables are still weaker than those made of metals such as copper, making them more susceptible to damage during installation and use, especially when subjected to external forces or bending. In addition, aluminum alloy cables have relatively poor stress relaxation and creep resistance, and are prone to shape and size changes over long-term use, affecting electrical performance and installation and maintenance. Summary of the Invention

[0009] An insulating protective layer is wrapped between the outer ends of multiple elastic reinforcing tubes. An intermediate positioning component covering the flow guide hole is rotatably connected between two adjacent partition rings. The intermediate positioning component includes an outer sheath, an inner pad ring sleeved on the outside of the core body is installed inside the outer sheath, and multiple flow guide channels matching the flow guide hole are opened on the inner pad ring. A planar groove is opened on the outer sheath, and an input tube communicating with the flow guide channel inside the inner pad ring is installed on the planar groove.

[0010] The outer end of the segmented reinforced sleeve is fitted with multiple auxiliary protective rings. Each auxiliary protective ring includes a pair of elastic retaining rings, and multiple pressure detectors are installed inside the elastic retaining rings. An outer probe and an inner probe are installed on the upper and lower sides of the pressure detectors, respectively. A buffer pad is installed on the top of the inner probe, and an arc-shaped buffer plate is installed on the outer probe. Multiple evenly distributed wire harness grooves are opened on the elastic retaining rings, and a terminal block matching the pressure detector is installed inside the wire harness grooves.

[0011] A reinforcing wire is threaded between multiple auxiliary protective rings. The reinforcing wire includes an inner wire harness, on which multiple terminals that match the terminal block are installed.

[0012] The aforementioned reinforced aluminum alloy cable facilitates testing of the cable installation environment and adjustment of the protective effect of each cable segment, enabling the cable to adapt to different installation environments.

[0013] As a further improvement of this application, a partition layer is provided in the middle of the elastic reinforcing tube, and multiple evenly distributed elastic support blocks are provided inside the elastic reinforcing tube.

The two ends of the temperature monitoring line are fixedly connected to two isolation rings respectively, and the isolation rings are equipped with a power connector that matches the temperature monitoring line.

[0016] As another improvement of this application, both ends of the inner wire harness are equipped with anchoring connectors that match the junction box. Signal lines connected in parallel with multiple connectors are installed on the anchoring connectors. The auxiliary protective ring is electrically connected to one connector through the junction box.

[0017] As a further improvement to this application, a protective monitoring system is also included. The protective monitoring system includes a processor, multiple temperature monitoring lines and auxiliary protective rings are electrically connected to the processor through reinforced lines, and the processor is connected to a data processing module, a monitoring module, an alarm module and a communication module.

[0018] The monitoring module is used to collect cable monitoring data, which includes temperature monitoring data of the temperature monitoring line and pressure monitoring data of the auxiliary protective ring.

[0019] The data processing module is used to process cable monitoring data and determine the cable's operating status;

[0040] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] Implementation method 1:

[0042] Figure 1-2The diagram illustrates a reinforced aluminum alloy cable. It includes a core body 1, on which multiple segmented reinforcing sleeves 2 are equidistantly arranged. Each segmented reinforcing sleeve 2 includes a pair of partition rings 201. Multiple elastic reinforcing tubes 202, arranged around the core body 1, are connected between the pair of partition rings 201. In this embodiment, the cable has two pairs of elastic reinforcing tubes 202. The partition rings 201 have flow guide holes communicating with the elastic reinforcing tubes 202. A partition layer is provided in the middle of each elastic reinforcing tube 202. Multiple evenly distributed elastic support blocks are provided inside each elastic reinforcing tube 202. The elastic support blocks enhance the elastic buffering effect of the elastic reinforcing tube 202. The elastic reinforcing tube 202 is configured with left and right sections so that when protective agents are simultaneously introduced at both ends of the elastic reinforcing tube 202, the tube can be quickly filled, facilitating rapid filling of the elastic reinforcing tube 202.

[0043] An insulating protective layer is wrapped between the outer ends of multiple elastic reinforcing tubes 202. An intermediate positioning member 4 covering the flow guide hole is rotatably connected between two adjacent partition rings 201. The intermediate positioning member 4 includes an outer sheath 401. An inner pad ring 402 sleeved on the outside of the core body 1 is installed inside the outer sheath 401. Multiple flow guide channels matching the flow guide hole are opened on the inner pad ring 402. Multiple output ports are provided in the flow guide channels. Each of the multiple output ports is connected to a flow guide hole. A flat groove is opened on the outer sheath 401. An input pipe communicating with the flow guide channel in the inner pad ring 402 is installed on the flat groove. The input end of the flow guide channel is connected to the input pipe.

[0044] When the intermediate positioning component 4 is initially installed, the flow channel is connected to the flow hole. At this time, the protective agent for cable protection can be introduced into the elastic reinforcing tube 202 through the input pipe and flow channel on the intermediate positioning component 4. The elastic reinforcing tube 202 can be filled with a portion of the protective agent as needed, such as pure water to improve the buffering effect of the elastic reinforcing tube 202 and flame retardant to improve the flame retardant effect.

[0045] When it is necessary to close the elastic reinforcing tube 202, rotate the intermediate positioning piece 4 to make the guide hole and the guide channel misaligned, so that the elastic reinforcing tube 202 can be closed; then use the fixing components to fix the intermediate positioning piece 4 and the partition ring 201, the fixing components include locking screws;

[0046] Optionally, the inner gasket ring 402 includes a pair of hollow semi-cylinders that interlock with each other. The flow channels inside the pair of hollow semi-cylinders are connected after they are interlocked. A one-way valve matching the flow channel is installed in the flow hole. By installing a one-way valve at the flow hole as the sealing component of the elastic reinforcing tube 202, the intermediate positioning part 4 can be kept fixed after installation, without the need for rotation to seal the output end of the elastic reinforcing tube 202. The protective agent is sealed when it is introduced into the elastic reinforcing tube 202.

[0047] A temperature monitoring line 3 is threaded through the elastic reinforcing tube 202. Multiple temperature sensing units are evenly distributed on the temperature monitoring line 3. The two ends of the temperature monitoring line 3 are fixedly connected to two isolation rings 201 respectively. A power connector 203 matching the temperature monitoring line 3 is installed on the isolation ring 201. The power connector 203 is connected to multiple temperature monitoring lines 3.

[0048] Multiple auxiliary protective rings 6 are sleeved on the outer end of the segmented reinforcing sleeve 2. Each auxiliary protective ring 6 includes a pair of elastic retaining rings 601. Multiple pressure detectors 602 are installed inside the elastic retaining rings 601. An outer probe 603 and an inner probe 604 are installed on the upper and lower sides of the pressure detectors 602, respectively. The outer probe 603 is used to detect external impact force, and the inner probe 604 is used to detect the expansion state after the cable is filled with protective agent. A buffer pad is installed at the top of the inner probe 604. The buffer pad is in contact with the insulation protective layer. An arc-shaped buffer plate 605 is installed on the outer probe 603. Both the buffer pad and the arc-shaped buffer plate 605 are used for the buffer protection of the cable.

[0049] The elastic retaining ring 601 has multiple evenly distributed wire harness slots, and a terminal block 606 matching the pressure detector 602 is installed in the wire harness slot; the arc-shaped buffer plate 605 covers the arc-shaped area on the surface of the elastic retaining ring 601 between two adjacent wire harness slots.

[0050] A reinforcing wire 5 is threaded between multiple auxiliary protective rings 6. The reinforcing wire 5 includes an inner wire harness 501, on which multiple connectors 502 that match the terminal block 606 are installed.

[0051] Both ends of the inner wiring harness 501 are equipped with anchoring connectors that match the power connector 203. Signal lines connected in parallel with multiple terminals 502 are installed on the anchoring connectors. The auxiliary protective ring 6 is electrically connected to a terminal 502 through the terminal block 606. The power connector 203 is connected to the signal line through the anchoring connector.

[0052] This embodiment, by incorporating segmented reinforcing sleeves 2, enhances the cable's local compressive strength while maintaining overall flexibility. The elastic reinforcing tubes 202 within the segmented reinforcing sleeves 2, through elastic support blocks, improve the elastic buffering effect, effectively absorbing external impacts and reducing the risk of cable damage. Furthermore, the fillability of the elastic reinforcing tubes 202 allows for the addition of different protective agents to the cable as needed.

[0053] Secondly, the design of the intermediate positioning component 4 not only facilitates the input of protective agent into the elastic reinforcing tube 202, but also enables the sealing of the elastic reinforcing tube 202 after the protective agent is filled by rotational misalignment, which is simple to operate and has significant effects.

[0054] By introducing temperature monitoring line 3 and auxiliary protective ring 6, the cable in this embodiment can monitor the internal temperature and external impact force of the cable in real time, providing an important guarantee for the safe operation of the cable. At the same time, temperature monitoring line 3 and auxiliary protective ring 6 can be connected to an external system through reinforcing line 5, enabling real-time transmission of cable monitoring data to the external system, facilitating the monitoring and management of the cable status.

[0055] The second implementation method:

[0056] Figure 7-8 As shown, it also includes a protective monitoring system, which includes a processor. Multiple temperature monitoring lines 3 and auxiliary protective rings 6 are electrically connected to the processor through reinforcing lines 5. 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 devices. A high-pressure pump used to input protective agent into the input pipe of the intermediate positioning component 4 is connected to the communication module via a signal.

[0057] The monitoring module is used to collect cable monitoring data, which includes: temperature monitoring data of temperature monitoring line 3 and pressure monitoring data of auxiliary protective ring 6;

[0058] The data processing module is used to process cable monitoring data and determine the cable operating status. When the pressure detection data of the auxiliary protection ring 6 is greater than the set value during the commissioning after cable laying, the data processing module calculates the amount of protective agent to be filled into the elastic reinforcing tube 202 based on the pressure detection data. The input amount of protective agent is proportional to the pressure detection value. A technical formula for setting the appropriate input amount of protective agent and the pressure detection value can be set by a person skilled in the art within the data processing module.

[0059] The alarm module is used to issue alarms when the cable is in an abnormal operating state.

[0060] An installation method for reinforced aluminum alloy cables includes:

[0061] A1. Lay the cable, lay the cable in the preset area;

[0062] 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 and the power connector 203 are connected to the signal of the external monitoring module through the reinforcement line 5. 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 rings 6 is wired.

[0063] A3, Post-cable laying commissioning: After the cable is laid, the pressure state of the auxiliary protection ring 6 is checked 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.

[0064] A31, when adjusting the segmented reinforcing sleeve 2, a protective agent is input into the elastic reinforcing tube 202 through the intermediate positioning component 4; during adjustment, the data processing module calculates the amount of protective agent input based on the pressure detection value, and then connects to the high-pressure pump through the communication module, so that the high-pressure pump inputs the protective agent into the input tube of the intermediate positioning component 4. The amount of protective agent input is proportional to the pressure detection value in A3. The protective agent includes flame retardant and pure water;

[0065] A32, when the pressure value detected in the inner probe 604 increases, shut down the high-pressure pump and stop the input of the protective agent;

[0066] A4, Cable fixing: Connect and fix the intermediate positioning piece 4 to the external bracket.

[0067] The cable installation method of this embodiment uses an auxiliary protective ring 6 and a reinforcing wire 5 to ensure 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 of 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 is always maintained in the best working condition.

[0068] The cable installation technology in this embodiment also places special emphasis on the commissioning process after cable laying. During the commissioning phase, based on the pressure status information fed back by the auxiliary protective ring 6, the required amount of protective agent input for the elastic reinforcing tube 202 is calculated. This allows for fine adjustment of the segmented reinforcing sleeve 2. During adjustment, protective agent is precisely injected into the elastic reinforcing tube 202. By filling the tube with protective agent, the cable's environmental adaptability is improved, while its compressive strength is also enhanced.

[0069] In addition, this embodiment also introduces a protection monitoring system. This system, through the connection of the processor with multiple temperature monitoring lines 3 and auxiliary protection rings 6, realizes comprehensive and real-time monitoring and efficient data processing of the cable's operating status. Once the cable's operating status becomes abnormal, the alarm module will immediately trigger the alarm mechanism to remind relevant personnel to respond quickly and handle the situation properly.

[0070] In summary, this embodiment achieves the goal of maintaining cable flexibility while enhancing local compressive strength through auxiliary protective ring 6 and segmented reinforcing sleeve 2. Furthermore, it facilitates cable condition adjustment based on the installation environment after installation and allows for real-time monitoring and intelligent management by an external system, ensuring the safe and stable operation of the cable.

[0071] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
