Description

Technical Field

[0001] This invention belongs to the field of cable structure technology, specifically relating to a multi-cable parallel anti-bias cable structure. Background Technology

[0002] Cable current imbalance prevention is a technical measure to address the problem of uneven current distribution in multi-core cables or cable bundles. When multiple cables transmit electrical energy in parallel, differences in conductor length, impedance, and asymmetrical laying paths, such as some cables being bent, near metal components, or with unbalanced loads, can easily lead to current concentration in a few cables, causing localized overheating, accelerated insulation aging, or even cable burnout, affecting power supply reliability. Current imbalance prevention requires a multi-pronged approach, addressing it from design, laying, and operation stages: selecting impedance-matched cables; optimizing laying paths to avoid uneven spacing, excessive bending, or proximity to magnetic materials; using current-sharing devices, such as current-sharing resistors and reactors, to balance the current; and monitoring the current and temperature of each cable during operation, adjusting the load or handling faults promptly to ensure even current distribution and guarantee the safe and stable operation of the cables.

[0003] When cables are laid at high altitudes, due to the weight of the cables themselves, there will be a certain degree of bending between the two fixing points after the cables are fixed at both ends. This means that when multiple cables are laid, if the degree of bending caused by the weight of each cable, such as the bending radius and the length of the bending section, is different, it will indirectly break the impedance balance through the bending difference, such as "uneven inductive reactance" and "increased local resistance" due to excessive bending, thus inducing or aggravating the bias current. 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 multi-cable parallel anti-bias cable structure.

[0005] The technical solution adopted to solve the above technical problems is: to provide a multi-cable parallel anti-bias cable structure, including a cable jacket mechanism, wherein the inside of the cable jacket mechanism is respectively provided with filler, cross-shaped separator and multiple conductor assemblies, the multiple conductor assemblies realize power transmission, and the filler and cross-shaped separator are used to separate the multiple conductor assemblies;

[0006] The outer wall of the cable jacket mechanism is provided with multiple internal connecting mechanisms. A top fixing mechanism and a bottom fixing mechanism are provided between the multiple internal connecting mechanisms. The top fixing mechanism and the bottom fixing mechanism connect and fix the multiple internal connecting mechanisms. A second bolt assembly is installed between the top fixing mechanism and the bottom fixing mechanism.

[0007] Furthermore, the cable sheath mechanism includes a cable outer sheath, the outer wall of which is fixedly connected with multiple integrally structured marking protrusions, the inner wall of which is provided with galvanized steel strip armor, and the inner wall of which is provided with an inner sheath.

[0008] Through the above technical solution, during the cable production process, based on the marking protrusions left on the outer wall when the cable sheath is extruded, and according to the cable's inherent strength, multiple equidistant marking points are selected for component installation. Multiple internal connection mechanisms are installed at these points, ensuring that the cable's bending degree between the two points remains within a safe range when fixed. Based on the position of the marking protrusions, four slots are opened at the marking points, which respectively penetrate the cable sheath, galvanized steel tape armor, and inner sheath, facilitating the installation of internal connection mechanisms. Simultaneously, during cable use, the galvanized steel tape armor and inner sheath enhance the overall cable's support strength.

[0009] Furthermore, the cross-shaped separator assembly includes a cross-shaped separator plate, and each port of the cross-shaped separator plate is fixedly connected to an integrated snap-fit ​​port.

[0010] With the above technical solution, after the opening is completed, the integrated locking port in the cross-shaped separator assembly is exposed, and the inclined structure at the top of the integrated locking port can guide the insertion of the internal connecting mechanism.

[0011] Furthermore, the conductor assembly includes a spiral copper wire assembly, the outer wall of which is provided with an inner shielding layer, the outer wall of which is provided with a cross-linked polyethylene insulation layer, and the outer wall of which is provided with a metal shielding layer.

[0012] The above technical solution uses multiple sets of spiral copper wire assemblies to complete power transmission. Cross-linked polyethylene insulation layer is used as the main insulation material to isolate the conductor from the external current, prevent leakage and short circuit, and ensure the safe power transmission of the cable.

[0013] Furthermore, the internal connection mechanism includes a U-shaped slot plate, the inner wall of which is provided with multiple integrated triangular limiting strips, and an L-shaped connecting strip is fixedly connected to the end of the U-shaped slot plate away from the triangular limiting strips. A rubber sealing sleeve is fixedly connected to the bottom of the outer wall of the L-shaped connecting strip.

[0014] With the above technical solution, after the opening is completed, the internal connecting mechanism is removed and waterproof glue is applied to the bottom of the rubber sealing sleeve. Then, the U-shaped slot plate in the internal connecting mechanism is inserted into the slot. Through the U-shaped structure at the bottom of the U-shaped slot plate, the filler on both sides is squeezed and inserted into the integrated locking port. The locking and fixing are achieved by the triangular limiting strip and the protrusion on the outer wall of the integrated locking port. The installation sequence of multiple internal connecting mechanisms is bottom, sides, and top. After inserting multiple internal connecting mechanisms, the opening can be sealed by multiple rubber sealing sleeves. The rubber sealing sleeve at the top covers the rubber sealing sleeves on both sides, and the bottom of the rubber sealing sleeves on both sides covers the bottom rubber sealing sleeve.

[0015] Furthermore, the cross-shaped dividing assembly, the U-shaped slot plate, and the multiple triangular limiting strips are all made of glass fiber reinforced polypropylene, and the multiple rubber sealing sleeves in the multiple internal connecting mechanisms are fitted together in pairs.

[0016] Through the above technical solution, the glass fiber reinforced polypropylene material can lead out the structural components and bear the strength and rigidity required for a certain suspension load, while maintaining the necessary insulation. Multiple rubber sealing sleeves fit together in pairs, and the structure can effectively prevent rainwater from entering the groove during external use.

[0017] Furthermore, the top fixing mechanism includes a connecting block, with an installation ring fixedly connected to the top of the connecting block. A set of first arc-shaped connecting rods are fixedly connected to both sides of the connecting block. A first L-shaped connecting plate is fixedly connected to the bottom center of the connecting block and the inner wall of one end of each of the two sets of first arc-shaped connecting rods. A first multi-hole connecting piece is fixedly connected to the outer wall of one end of each of the two sets of first arc-shaped connecting rods. A first limiting sleeve and two second limiting sleeves are slidably connected to the plurality of first L-shaped connecting plates, with the first limiting sleeve located at the bottom center of the connecting block. A first limiting rod is fixedly connected to the front and rear ends of the plurality of first L-shaped connecting plates. A rubber open ring is fixedly connected to the bottom of the front and rear faces of the first limiting sleeve. A set of fixing shafts is fixedly connected to the front and rear faces of the first limiting sleeve. A corresponding set of locking clamps is rotatably connected to each of the two sets of fixing shafts. A first bolt assembly is provided at the bottom of each of the two sets of locking clamps.

[0018] With the above technical solution, when laying the cable, the internal connection mechanism at the top is determined according to the order in which multiple rubber sealing sleeves are pressed together. Then, the first limiting sleeve and two second limiting sleeves in the top fixing mechanism are pushed outward to expose the L-shaped structure on one side of multiple first L-shaped connecting plates. This structure is then slidably connected between the top internal connection mechanism and the two side internal connection mechanisms. After that, the first limiting sleeve and two second limiting sleeves are reset to complete the connection between the L-shaped connecting strip and the first L-shaped connecting plate. During the installation process, the bottom openings of the two rubber open rings can be opened so that they can be fitted onto the front and rear ends of the multiple rubber sealing sleeves.

[0019] Furthermore, the bottom fixing mechanism includes two second arc-shaped rods, a second L-shaped connecting plate is fixedly connected to the bottom between the two second arc-shaped rods, a second multi-hole connecting piece is fixedly connected between both ends of the two second arc-shaped rods, a third limiting sleeve is slidably connected to the outer wall of the second L-shaped connecting plate, a second limiting rod is fixedly connected to the front end face and the rear end face of the third limiting sleeve, connecting ears are fixedly connected to both sides of the inner wall of the two second arc-shaped rods, a threaded rod passes through the connecting ear, a nut assembly is provided on the outer wall of one end of the threaded rod, and a connecting steel cable is fixedly connected to the other end of the threaded rod.

[0020] Through the above technical solution, the bottom fixing mechanism is similarly installed to complete the engagement of the second L-shaped connecting plate. Multiple second bolt assemblies are used to fix the top and bottom fixing mechanisms. During further limiting, two sets of locking clamps are rotated to compress the outer walls of the two rubber open rings, engage multiple first and second limiting rods, and finally fix the system using the first bolt assembly. This compression of the two rubber open rings and multiple rubber sealing sleeves achieves effective sealing, preventing rainwater from entering. Simultaneously, the engagement of the multiple first and second limiting rods limits the movement of the first limiting sleeve, two second limiting sleeves, and a third limiting sleeve. Finally, a connecting steel cable is installed between the two marked points, connected by threaded rods and nut assemblies at both ends. This establishes two connecting steel cables between the two points, further supporting the cable body and preventing significant bending due to the cable's own weight.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention designs a top fixing mechanism and a top fixing mechanism. When the cable is laid, the top fixing mechanism and the top fixing mechanism are installed according to the points of multiple internal connection mechanisms designed and installed to fix the cable. Between two marked points, connecting steel cables are installed and connected by the threaded rods and nut assemblies at both ends of the connecting steel cables. This achieves the setting of two connecting steel cables between the two points, further realizing the support of the cable body and avoiding large bending of the cable due to its own weight. Within the distance between the two points, the cable bending is further avoided by the two connecting steel cables set on both sides of the bottom of the cable. (1) This avoids the increased probability of multiple cables deflecting due to bending; (2) This invention installs the internal connection mechanism during cable production and avoids measurement work during subsequent cable laying according to the factory-designed point markings, ensuring that the top fixing mechanism and top fixing mechanism can be quickly installed during subsequent laying. In addition, by designing rubber sealing sleeves, the top rubber sealing sleeve covers the rubber sealing sleeves on both sides, and the bottom of the rubber sealing sleeves on both sides covers the bottom rubber sealing sleeves on both sides. During external use, this structure can effectively prevent rainwater from entering the groove. It can be sealed again during subsequent laying and installation, further improving the waterproof effect. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] like Figures 1-5As shown, this embodiment of a multi-cable parallel anti-bias cable structure includes a cable jacket mechanism 1, which includes a cable outer sheath 101. Multiple integrally formed marking protrusions 102 are fixedly connected to the outer wall of the cable outer sheath 101. A galvanized steel strip armor 103 is provided on the inner wall of the cable outer sheath 101, and an inner sheath 104 is provided on the inner wall of the galvanized steel strip armor 103. During cable production, based on the marking protrusions 102 left on the outer wall when the cable outer sheath 101 is extruded, and based on the cable's inherent strength... Multiple equidistant marking points are selected for component installation. Multiple internal connection mechanisms 5 are installed at these points to ensure that the bending degree of the cable between the two points is within a safe range when the two points are fixed. Based on the position of the marking protrusions 102, four slots are made at the marking points to pass through the cable outer sheath 101, galvanized steel tape armor 103, and inner sheath 104, respectively, thereby facilitating the installation of the internal connection mechanisms 5. At the same time, during cable use, the galvanized steel tape armor 103 and inner sheath 104 can improve the overall support strength of the cable.

[0037] like Figures 1-6 As shown, the cable jacket mechanism 1 is internally equipped with a filler 2, a cross-shaped separator 3, and multiple conductor assemblies 4. The multiple conductor assemblies 4 enable power transmission. The filler 2 and the cross-shaped separator 3 are used to separate the multiple conductor assemblies 4. The cross-shaped separator 3 includes a cross-shaped separator plate 31. Each port of the cross-shaped separator plate 31 is fixedly connected to an integrated snap-fit ​​port 32. After the opening is completed, the integrated snap-fit ​​port 32 in the cross-shaped separator 3 is exposed. The inclined structure at the top of the integrated snap-fit ​​port 32 can guide the internal connection mechanism 5 to be inserted. The conductor assembly 4 includes a spiral copper wire assembly 401. The outer wall of the spiral copper wire assembly 401 is provided with an inner shielding layer 402. The outer wall of the inner shielding layer 402 is provided with a cross-linked polyethylene insulation layer 403. The outer wall of the cross-linked polyethylene insulation layer 403 is provided with a metal shielding layer 404. Power transmission is accomplished through multiple sets of spiral copper wire assemblies 401. The cross-linked polyethylene insulation layer 403 serves as the main insulation material, isolating the conductor from the external current, preventing leakage and short circuits, and ensuring the safe power transmission of the cable.

[0038] like Figures 1-7As shown, the outer wall of the cable jacket mechanism 1 is provided with multiple internal connecting mechanisms 5. Each internal connecting mechanism 5 includes a U-shaped slotted plate 501. The inner wall of the U-shaped slotted plate 501 is provided with multiple integrated triangular limiting strips 502. An L-shaped connecting strip 503 is fixedly connected to the end of the U-shaped slotted plate 501 away from the triangular limiting strip 502. A rubber sealing sleeve 504 is fixedly connected to the bottom of the outer wall of the L-shaped connecting strip 503. After opening, the internal connecting mechanism 5 is removed, and waterproof adhesive is applied to the bottom of the rubber sealing sleeve 504. Then, the U-shaped slotted plate 501 in the internal connecting mechanism 5 is inserted into the slot. Through the U-shaped structure at the bottom of the U-shaped slotted plate 501, the filler material 2 on both sides is squeezed and inserted into the integrated engaging port 32. The engaging and fixing is achieved through the triangular limiting strip 502 and the protrusion on the outer wall of the integrated engaging port 32. Multiple internal... The installation sequence of the connecting mechanism 5 is bottom, sides, and top. After inserting multiple internal connecting mechanisms 5, the opening can be sealed by multiple rubber sealing sleeves 504. The top rubber sealing sleeve 504 covers the sides of the rubber sealing sleeves 504, and the sides of the rubber sealing sleeves 504 cover the bottom sides of the bottom rubber sealing sleeve 504. The cross-shaped dividing component 3, the U-shaped slot plate 501, and multiple triangular limiting strips 502 are all made of glass fiber reinforced polypropylene. The multiple rubber sealing sleeves 504 in the multiple internal connecting mechanisms 5 are fitted together in pairs. The glass fiber reinforced polypropylene material can lead out the structural components and bear the strength and rigidity required for a certain suspension load, while maintaining the necessary insulation. The multiple rubber sealing sleeves 504 are fitted together in pairs. During external use, this structure can effectively prevent rainwater from entering the slot.

[0039] like Figures 1-10As shown, a top fixing mechanism 6 and a bottom fixing mechanism 7 are provided between multiple internal connecting mechanisms 5. The top fixing mechanism 6 and the bottom fixing mechanism 7 connect and fix the multiple internal connecting mechanisms 5. The top fixing mechanism 6 includes a connecting block 601, and a mounting ring 602 is fixedly connected to the top of the connecting block 601. A set of first arc-shaped connecting rods 603 are fixedly connected to both sides of the connecting block 601. The bottom center of the connecting block 601 and the inner wall of one end of each of the two sets of first arc-shaped connecting rods 603 are fixedly connected to... The outer wall of one end of each of the first L-shaped connecting plate 604 and the two sets of first arc-shaped connecting rods 603 is fixedly connected with a first multi-hole connecting piece 605. A first limiting sleeve 606 and two second limiting sleeves 607 are slidably connected to the multiple first L-shaped connecting plates 604, with the first limiting sleeve 606 located at the center of the bottom of the connecting block 601. The front and rear ends of the multiple first L-shaped connecting plates 604 are fixedly connected with first limiting rods 608. The bottom of the front and rear faces of the first limiting sleeves 606 are fixedly connected with... A rubber open ring 609 is provided. A set of fixed rotating shafts 610 are fixedly connected to both the front and rear faces of the first limiting sleeve 606. A corresponding set of locking clamps 611 are rotatably connected to each of the two sets of fixed rotating shafts 610. A first bolt assembly 612 is provided at the bottom of each of the two sets of locking clamps 611. During cable laying, the internal connecting mechanism 5 at the top is determined based on the sequence of mutual pressing of the multiple rubber sealing sleeves 504. Then, the first limiting sleeve 606 and the two second limiting sleeves in the top fixing mechanism 6 are connected... The sleeve 607 is pushed outward to expose the L-shaped structure on one side of the multiple first L-shaped connecting plates 604, which is then slidably connected between the top internal connecting mechanism 5 and the two side internal connecting mechanisms 5. Then, the first limiting sleeve 606 and the two second limiting sleeves 607 are reset to complete the connection between the L-shaped connecting strip 503 and the first L-shaped connecting plate 604. During the installation process, the bottom openings of the two rubber open rings 609 can be opened so that they can be fitted onto the front and rear ends of the multiple rubber sealing sleeves 504.

[0040] like Figures 1-12As shown, the bottom fixing mechanism 7 includes two second arc-shaped rods 701. A second L-shaped connecting plate 702 is fixedly connected to the bottom between the two second arc-shaped rods 701. A second multi-hole connecting piece 703 is fixedly connected between both ends of the two second arc-shaped rods 701. A third limiting sleeve 704 is slidably connected to the outer wall of the second L-shaped connecting plate 702. A second limiting rod 705 is fixedly connected to both the front and rear faces of the third limiting sleeve 704. Connecting ears 706 are fixedly connected to both sides of the inner walls of the two second arc-shaped rods 701. A threaded rod 707 passes through the connecting ear 706. A nut assembly 708 is provided on the outer wall of one end of the threaded rod 707. A connecting steel cable 709 is fixedly connected to the other end of the threaded rod 707. Similarly, the bottom fixing mechanism 7 is installed to complete the engagement of the second L-shaped connecting plate 702. The top fixing mechanism 6 and the bottom fixing mechanism 7 are fixed by multiple second bolt assemblies 8. When further limiting, the two sets of locks are rotated. The clamp 611 is tightened to compress the outer walls of the two rubber open rings 609, engage the multiple first limiting rods 608 and the second limiting rods 705, and finally fix them with the first bolt assembly 612. This effectively seals the two rubber open rings 609 and the multiple rubber sealing sleeves 504, preventing rainwater from entering. Simultaneously, the engagement of the multiple first limiting rods 608 and the second limiting rods 705 prevents the first limiting sleeve 606, the two second limiting sleeves 607, and the third limiting sleeve 704 from sliding freely. Finally, a connecting steel cable 709 is installed between the two marked points, connected by the threaded rods 707 and the nut assembly 708 at both ends of the connecting steel cable 709. This establishes two connecting steel cables 709 between the two points, further supporting the cable body and preventing significant bending due to its own weight. A second bolt assembly 8 is installed between the top fixing mechanism 6 and the bottom fixing mechanism 7.

[0041] The working principle of this embodiment is as follows: During the cable production process, based on the marking protrusions 102 left on the outer wall when the cable outer sheath 101 is extruded, and according to the cable's own strength, multiple equidistant marking points are selected for component installation. Multiple internal connecting mechanisms 5 are installed at these points so that when two points are fixed, the bending degree of the cable between them is within a safe range. Based on the position of the marking protrusions 102, four slots are opened at the marking points, respectively penetrating the cable outer sheath 101, the galvanized steel strip armor 103, and the inner sheath 104, thereby exposing the integrated locking port 32 in the cross-separation assembly 3. The internal connecting mechanism 5 is removed, and waterproof glue is applied to the bottom of the rubber sealing sleeve 504. Then, the internal connecting mechanism 5 is installed. The U-shaped slot plate 501 in structure 5 is inserted into the slot. Through the U-shaped structure at the bottom of the U-shaped slot plate 501, the filler material 2 on both sides is squeezed and then inserted into the integrated locking port 32. The locking and fixing are achieved by the triangular limiting strip 502 and the protrusion on the outer wall of the integrated locking port 32. The installation sequence of multiple internal connecting mechanisms 5 is bottom, sides, and top. After inserting multiple internal connecting mechanisms 5, the opening can be sealed by multiple rubber sealing sleeves 504. The top rubber sealing sleeve 504 covers the sides rubber sealing sleeves 504 on both sides, and the bottom of the sides rubber sealing sleeves 504 covers the sides of the bottom rubber sealing sleeve 504. During external use, this structure can effectively prevent rainwater from entering the slot.

[0042] During cable laying, the internal connecting mechanism 5 at the top is determined according to the order in which multiple rubber sealing sleeves 504 are pressed together. Then, the first limiting sleeve 606 and two second limiting sleeves 607 in the top fixing mechanism 6 are pushed outward to expose the L-shaped structure on one side of multiple first L-shaped connecting plates 604. This structure is then slidably connected between the top internal connecting mechanism 5 and the two side internal connecting mechanisms 5. After that, the first limiting sleeve 606 and two second limiting sleeves 607 are reset to complete the connection between the L-shaped connecting strip 503 and the first L-shaped connecting plate 604. During the installation process, the bottom openings of the two rubber open rings 609 can be opened to fit onto the front and rear ends of the multiple rubber sealing sleeves 504. Finally, the bottom fixing mechanism 7 is installed in the same way to complete the engagement of the second L-shaped connecting plate 702. The top fixing mechanism 6 and the bottom fixing mechanism 7 are then fixed by multiple second bolt assemblies 8.

[0043] During further limiting, the two sets of locking clamps 611 are rotated to compress the outer walls of the two rubber open rings 609 and engage the multiple first limiting rods 608 and the second limiting rods 705 respectively. Finally, the first bolt assembly 612 is used to fix them. In turn, by compressing the two rubber open rings 609 and the multiple rubber sealing sleeves 504, an effective seal is achieved to prevent rainwater from entering. At the same time, by engaging and limiting the multiple first limiting rods 608 and the second limiting rods 705, the first limiting sleeve 606, the two second limiting sleeves 607 and the third limiting sleeve 704 are prevented from sliding freely.

[0044] Finally, a connecting steel cable 709 is installed between the two marked points. The connecting steel cable 709 is connected by the threaded rod 707 and nut assembly 708 at both ends, thereby setting two connecting steel cables 709 between the two points, which further supports the main body of the cable and prevents the cable from bending significantly due to its own weight.

[0045] 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.
