Description

Technical Field

[0001] This invention belongs to the field of cable technology, specifically relating to a flexible, multi-resistant, fire-resistant insulated cable. Background Technology

[0002] Flexible fireproof cable is a special cable designed for high-temperature extreme environments such as fires. It combines the two core functions of flexible laying and continuous power supply in fire. Through a special combination of materials and structure, it can maintain circuit integrity in high-temperature flame environments. At the same time, like ordinary power cables, it can be coiled and turned to adapt to complex laying paths.

[0003] However, existing flexible fire-resistant cables have room for improvement in terms of long-term stability and thermal shock protection of their internal structure. For example, their thick insulation layer greatly sacrifices flexibility, thus reducing ease of use in fire and high-temperature environments. Furthermore, existing flexible fire-resistant cables still have the potential for internal combustion and damage in fire and high-temperature environments. Their thick protective layer makes it difficult for operators to visually identify the internal condition of the cable, greatly increasing the risk of use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a flexible, multi-resistant, fire-resistant insulated cable.

[0005] The technical solution adopted to solve the above technical problems is: a flexible multi-resistance insulated fireproof cable, including an outer protective sleeve, an indicator clamp wrapped around the outside of the outer protective sleeve, fireproof putty filling the inside of the outer protective sleeve, a shaping sleeve attached to the inside of the fireproof putty, a plurality of copper sleeves arranged inside the shaping sleeve, and filler tape arranged between the plurality of copper sleeves.

[0006] Furthermore, the fireproof putty is provided with a partition ring inside, and a fixing component is installed between several of the copper sleeves, with the middle part of the fixing component being fixedly connected to the filler wire strip.

[0007] The above technical solution forms a multi-layered isolation structure, which effectively prevents the transmission of high temperature. The synergistic effect of the isolation ring and the fixing components enhances the stability of the internal structure of the cable. Even in extreme high temperature environments, the relative position of the copper sleeve and the filler tape remains unchanged, preventing internal structural damage caused by thermal expansion.

[0008] Furthermore, the center of the prompt clamp, the fixing component, and the partition ring are aligned together.

[0009] The above technical solutions ensure that the cable's structure remains relatively stable when subjected to external forces or high temperatures, preventing any impact on its overall performance and safety due to displacement or misalignment. This also makes installation and maintenance more convenient, improving work efficiency.

[0010] Furthermore, the prompting clamp includes two semicircular rings, with a column fixedly connected to the middle of the two semicircular rings, and concave rings fixedly connected to both ends of the two semicircular rings respectively. One concave ring has a second retaining ring rotatably connected to both sides, and the other concave ring has a first retaining ring rotatably connected to the inner side. The first retaining ring and the second retaining ring respectively rotatably engage with the concave ring on the other semicircular ring.

[0011] The above technical solution suggests that the clamp adopts this unique design, which allows the two semi-circular rings to be easily opened and closed, facilitating the installation and disassembly of the cable. The rotating engagement design of the concave ring with the first and second retaining rings further ensures the clamp's firmness in the closed state, effectively preventing the clamp from accidentally loosening, thereby better protecting the cable and ensuring its safe and stable operation in various complex environments.

[0012] Furthermore, an extension plate is fixedly connected to the end of the second retaining ring away from the concave ring. The extension plate is in contact with another semi-circular ring. A bolt structure is provided between the extension plate and the semi-circular ring. A retaining seat is fixedly connected to the surface of the concave ring. A retaining block is fixedly connected to both sides of the end of the first retaining ring away from rotation. The retaining block and the retaining seat are slidably engaged.

[0013] The above technical solution, with its extension plate and bolt structure, provides an additional fixing method for the clamp's closure, enhancing its stability after closure and preventing it from loosening when the cable is subjected to external pulling or vibration. The sliding engagement design of the clamp seat and the clamp block further improves the convenience and robustness of clamp closure. Operators simply slide the clamp block into the clamp seat to achieve rapid clamp closure, and this engagement method effectively prevents the clamp from opening on its own during operation, providing a reliable guarantee for the safe operation of the cable.

[0014] Furthermore, a magnetic sheet is slidably connected to one end of the column near the semi-circular ring. A secondary column is fixedly connected to one end of the magnetic sheet inside the column. A guide plate is fixedly connected to the other end of the secondary column away from the magnetic sheet. A spring sheet is attached to one side surface of the guide plate where the secondary column is located. Both ends of the spring sheet are fixedly connected to the inside of the column.

[0015] Through the above technical solution, the connection design between the magnetic sheet and the secondary column and guide plate, combined with the elastic effect of the spring, allows the magnetic sheet to retract into the column when not subjected to external magnetic field force. At the same time, the spring also serves as a buffer and reset mechanism, ensuring the stability and reusability of the magnetic sheet after sliding.

[0016] Furthermore, the inside of the column is rotatably connected to the upper and lower parts respectively. A first pull plate is fixedly connected to one side of the pull plate. The first pull plate is engaged and slidably connected to the guide rail plate. A second pull plate is fixedly connected to the end of the pull plate away from the first pull plate. A sliding groove is engaged and driven to the end of the second pull plate away from the pull plate. A limit plate is fixedly connected to several sliding grooves.

[0017] Furthermore, the column is rotatably connected to the upper and lower ends on the side away from the semicircular ring. The folded corner of the folded strip is rotatably connected to the column. A prompting plate is fixedly connected to the end of the folded strip outside the column. A fan-shaped block is fixedly connected to the end of the folded strip away from the prompting plate. A thin spring is provided between the two fan-shaped blocks. The surface of the fan-shaped block is attached to and slidably connected to the surface of the limiting plate.

[0018] With the above technical solution, when the magnetic sheet is affected by temperature, the magnetic sheet moves. The first pull plate and the guide rail plate push the rotating shaft to rotate. The second pull plate pulls the limiting plate through the slide groove, so that the limiting plate is separated from the sector block. Under the action of the spring, the folding strip rotates. The operator can observe the degree of rotation of the indicator plate to judge the internal temperature of the cable, avoid internal fire, and improve the safety of the cable.

[0019] Furthermore, the fixing component includes a ring body with recessed grooves evenly arranged on its surface. A plurality of square posts are disposed between the inner ring and the surface of the ring body, and the square posts are located between the recessed grooves. A fixing blade is fixedly connected to one end of each square post on the outer side. A copper sleeve is located between the recessed groove and the fixing blade. A pin is fixedly connected to one end of each square post away from the fixing blade. The pin is engaged and slidably connected with the filler wire.

[0020] Through the above technical solution, the recessed groove and fixing blade can fix the copper sleeve inside the cable. With the external clamping reminder clamp, the stability of the copper sleeve is further enhanced, avoiding displacement and entanglement of the internal copper sleeve during daily use. At the same time, the gap formed between the fixing components allows for efficient exchange and dispersion of internal temperature, avoiding the accumulation of high temperature and improving the service life of the cable.

[0021] Furthermore, the partition ring has a T-shaped cross-section, and a thermoplastic magnetic ring is provided on the outer surface of the partition ring, which is attracted to the magnetic sheet.

[0022] Through the above technical solution, the T-shaped cross-section partition ring can effectively divide the internal space of the cable, ensuring the independence of the functions of each part.

[0023] Furthermore, the inner side of the outer protective sleeve is provided with a first wrapping tape, the inner side of the first wrapping tape is respectively attached to the surface of the fireproof putty and the partition ring, the copper sleeve includes a copper core, the surface of the copper core is wrapped with a mother tape, the outer surface of the mother tape is wrapped with a second wrapping tape, the second wrapping tape is respectively in contact with and attached to the recessed groove and the fixing blade.

[0024] Through the above technical solutions, the design of the first wrapping tape not only enhances the tight connection between the outer protective sheath and the internal structure, but also provides initial fireproofing and insulation. The filling of fireproof putty further improves the cable's fire resistance, effectively preventing the spread of fire. As the core component of the cable, the copper core, with its surface wrapped with mother tape, not only enhances conductivity but also provides a certain degree of mechanical protection. The second wrapping tape fits tightly against the outer surface of the mother tape, and its contact design with the recessed grooves and fixing blades makes the copper sheath more stable inside the cable, less prone to displacement or damage, thus ensuring the long-term stable operation of the cable.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. This invention, through a cuff comprising a magnetic sheet, a thermoplastic magnetic ring, and a mechanical linkage structure, can convert changes in magnetic attraction caused by temperature variations inside the cable into changes in the angle of an externally visible indicator board. This enables real-time, intuitive monitoring and early warning of the cable's internal operating temperature, allowing operators to quickly determine whether there is overheating or potential fire hazard inside the cable without removing the heavy protective layer. This greatly improves the safety of the cable in high-risk fire environments and reduces the risk of hidden internal damage.

[0027] 2. This invention achieves stable, independent, and flexible fixing of multiple copper sleeves through a fixing assembly consisting of a ring, a recessed groove, a fixing blade, and a square column, which works in conjunction with an external clamp. While ensuring the overall flexibility of the cable and facilitating its installation, it effectively prevents displacement, entanglement, or structural damage to the internal conductors caused by long-term use or thermal shock, thus balancing the two core requirements of flexibility and stability.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] like Figures 1 to 11As shown, this embodiment of a flexible, multi-resistant, fire-resistant insulated cable includes an outer protective sleeve 1, with a warning clamp 2 wrapped around the outside of the outer protective sleeve 1, fireproof putty 3 filling the inside of the outer protective sleeve 1, a shaping sleeve 4 attached to the inside of the fireproof putty 3, a plurality of copper sleeves 5 disposed on the inside of the shaping sleeve 4, and a filler tape 8 disposed between the plurality of copper sleeves 5, and a first wrapping tape 101 disposed on the inside of the outer protective sleeve 1, the inside of the first wrapping tape 101 being attached to the surfaces of the fireproof putty 3 and the isolation ring 7 respectively. While ensuring the overall flexibility of the cable and facilitating its laying, it effectively prevents displacement, entanglement or structural damage of the internal conductors due to long-term use or thermal shock, thus taking into account both the two core requirements of flexibility and stability.

[0042] like Figures 1 to 3 As shown, the fireproof putty 3 has an isolation ring 7 inside, and a fixing component 6 is installed between several copper sleeves 5. The middle part of the fixing component 6 is fixedly connected to the filler wire strip 8. The isolation ring 7 and the fixing component 6 work together to enhance the stability of the internal structure of the cable. Even in extreme high temperature environments, the relative position of the copper sleeves 5 and the filler wire strip 8 can remain unchanged, preventing the internal structure from being damaged due to thermal expansion.

[0043] like Figures 1 to 3 As shown, the common center of the clamp 2, fixing component 6, and isolation ring 7 are aligned, which makes the installation and maintenance of the cable more convenient and improves work efficiency.

[0044] like Figures 4 to 5 As shown, the cuff 2 includes two semicircular rings 201. The cuff 2 adopts this unique design, which allows the two semicircular rings 201 to be opened and closed easily. A column 202 is fixedly connected to the middle of the two semicircular rings 201, and concave rings 205 are fixedly connected to both ends of the two semicircular rings 201. A second retaining ring 207 is rotatably connected to both sides of one concave ring 205, and a first retaining ring 206 is rotatably connected to the inner side of the other concave ring 205. The first retaining ring 206 and the second retaining ring 207 respectively rotatably engage with the concave ring 205 on the other semicircular ring 201.

[0045] like Figures 5 to 6 As shown, the end of the second retaining ring 207 away from the concave ring 205 is fixedly connected to an extension plate 208. The extension plate 208 fits against another semi-circular ring 201. A bolt structure 209 is provided between the extension plate 208 and the semi-circular ring 201. A retaining seat 210 is fixedly connected to the surface of the concave ring 205. The two sides of the end of the first retaining ring 206 away from rotation are fixedly connected to retaining blocks 211 respectively. The retaining blocks 211 and retaining seats 210 slide and engage, which further ensures the firmness of the reminder clamp 2 in the closed state and can effectively prevent the reminder clamp 2 from being accidentally loosened, thereby better protecting the cable and ensuring that the cable can operate safely and stably in various complex environments.

[0046] like Figures 7 to 8As shown, a magnetic sheet 204 is slidably connected to one end of the column 202 near the semi-circular ring 201. A secondary column 212 is fixedly connected to one end of the magnetic sheet 204 inside the column 202. A guide plate 222 is fixedly connected to the other end of the secondary column 212 away from the magnetic sheet 204. A spring piece 213 is attached to one side surface of the guide plate 222 where the secondary column 212 is located. Both ends of the spring piece 213 are fixedly connected to the inside of the column 202. The spring piece 213 also plays a role in buffering and resetting, ensuring the stability and reusability of the magnetic sheet 204 after sliding.

[0047] like Figures 7 to 8 As shown, the column 202 has rotating shafts 221 rotatably connected to its upper and lower sides. A first pull plate 214 is fixedly connected to one side of the rotating shaft 221, and the first pull plate 214 is engaged and slidably connected to the guide rail plate 222. A second pull plate 215 is fixedly connected to the end of the rotating shaft 221 away from the first pull plate 214. A sliding groove 216 is engaged and driven at the end of the second pull plate 215 away from the rotating shaft 221. A limit plate 217 is fixedly connected to several sliding grooves 216. The upper and lower ends of the column 202 away from the semicircular ring 201 are rotatably connected to... There is a folded strip 220, and the folded corner of the folded strip 220 is rotatably connected to the column 202. One end of the folded strip 220 located outside the column 202 is fixedly connected to an indicator plate 203. The other end of the folded strip 220 away from the indicator plate 203 is fixedly connected to a fan-shaped block 219. A thin spring 218 is set between the two fan-shaped blocks 219. The surface of the fan-shaped block 219 is attached to and slidably connected to the surface of the limiting plate 217. The operator can observe the degree of rotation of the indicator plate 203 to judge the internal temperature of the cable, avoid internal fire, and improve the safety of the cable.

[0048] like Figure 9 As shown, the fixing component 6 includes a ring 601. The surface of the ring 601 is uniformly arrayed with recessed grooves 602. Several square posts 603 are arranged through the inner ring of the ring 601 and the surface. The square posts 603 are located between the recessed grooves 602. A fixing blade 604 is fixedly connected to the outer end of the square post 603. The copper sleeve 5 is located between the recessed grooves 602 and the fixing blade 604. A pin 605 is fixedly connected to the end of the square post 603 away from the fixing blade 604. The pin 605 is engaged and slidably connected with the filler tape 8. The recessed grooves 602 and the fixing blade 604 can fix the copper sleeve 5 inside the cable. With the external clamping clamp 2, the fixing stability of the copper sleeve 5 is further enhanced.

[0049] like Figure 10 As shown, the partition ring 7 has a T-shaped cross-section, which can effectively divide the internal space of the cable and ensure the independence of the functions of each part. A thermoplastic magnetic ring 701 is provided on the outer surface of the partition ring 7, and the thermoplastic magnetic ring 701 and the magnetic sheet 204 are attracted to each other.

[0050] like Figure 11 As shown, the copper sleeve 5 includes a copper core 501, with a mother tape 502 wrapped around the surface of the copper core 501. A second wrapping tape 503 is wrapped around the outer surface of the mother tape 502. The second wrapping tape 503 contacts and adheres to the recessed groove 602 and the fixed blade 604 respectively. The second wrapping tape 503 is tightly attached to the outer surface of the mother tape 502. The contact design with the recessed groove 602 and the fixed blade 604 makes the copper sleeve 5 more stable inside the cable, less prone to displacement or damage, thereby ensuring the long-term stable operation of the cable.

[0051] The working principle of this embodiment is as follows:

[0052] Under normal operating conditions, the internal structure of the cable works together to ensure stability and safety. The fireproof putty 3 and the internal T-shaped isolation ring 7 together form a multi-layered, segmented heat insulation barrier, which can effectively block the direct influence of external ambient temperature. The fixing component 6 uses the recessed groove 602 and fixing blade 604 on its ring body 601 to firmly engage each copper sleeve 5, which is composed of copper core 501, mother tape 502 and second wrapping tape 503, in the predetermined position. At the same time, the pin 605 in its square post 603 engages with the filler tape 8, ensuring the integrity and relative positional stability of the internal cable structure, so that the cable is flexible while its impact resistance and deformation resistance are significantly enhanced.

[0053] When a fire or abnormally high temperature occurs in the environment where the cable is located, its unique early warning mechanism will be triggered. Heat is transferred inward through the outer protective sleeve 1 and the first wrapping tape 101, causing the temperature of the isolation ring 7 embedded in the fireproof putty 3 to rise. After reaching a certain critical temperature, the magnetism of the thermoplastic magnetic ring 701 on the surface of the isolation ring 7 will be significantly weakened or disappear.

[0054] At this point, the magnetic force balance between the magnetic sheet 204 inside the clamp 2 column 202 and the thermoplastic magnetic ring 701 is broken. Under the elastic restoring force of the spring sheet 213, the magnetic sheet 204 drives the secondary column 212 and the guide plate 222 to slide into the column 202.

[0055] The movement of the guide plate 222 pushes the first pull plate 214 that meshes with it, thereby driving the rotating shaft 221 to rotate. The rotation of the rotating shaft 221 causes the second pull plate 215 on the other side to move. The second pull plate 215 pulls the limiting plate 217 along a predetermined path through the sliding groove 216 that meshes with it, so that it slides off the surface of the two sector blocks 219.

[0056] Once the limiting plate 217 releases its restriction on the sector blocks 219, the two sector blocks 219, under the expansion force of the central thin spring 218, push the fixed fold strip 220 to rotate around its central fold angle. The indicator plate 203 at the outer end of the fold strip 220 then pops outward from its state of being attached to the column 202, forming a clear visual warning angle.

[0057] By observing the pop-up status of the indicator panel 203, operators can intuitively and quickly determine that the inside of the cable is in a high-temperature hazardous environment, potentially indicating insulation damage or fire risk. This allows for timely action such as power outages, evacuation, or fire suppression. This early warning mechanism does not require damage to the cable structure, enabling non-contact, visual monitoring of the internal condition and significantly improving the safety and maintainability of cables used in complex or hazardous environments.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
