[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0020] See also Figure 1-5An overhead insulated power cable includes a cable body, the cable body includes an internal conductive core 4, an external insulating layer 2, and a core wrapping layer 3 filled between the conductive core 4 and the insulating layer 2. Support components 5 are provided on the top and bottom of the insulating layer 2. The two support components 5 are located in the same vertical plane and are arranged in parallel. A protective layer 1 is provided on the outside of the insulating layer 2 to wrap the support components 5. The support member 5 includes horizontal bending hinges 501 connected in series to form a chain shape. The axial direction of the horizontal bending hinge 501 is consistent with the radial direction of the cable body, so that the horizontal bending hinge 501 can bend in a plane parallel to the axial direction of the cable body. By providing a support component 5, the support component 5 is composed of a plurality of horizontal bending hinges 501 in series, and the horizontal bending hinge 501 is arranged in a manner such that the axial direction is consistent with the radial direction of the cable body, so that the horizontal bending hinge 501 cannot be bent up and down, but can be bent horizontally. After the cable body is installed overhead, the horizontal bending hinge 501 is used to bear the weight of the cable, thereby preventing the cable from falling significantly and not affecting the change of the horizontal direction of the cable body, which is convenient for changing the direction when laying the cable. During installation, it can be directly hoisted and fixed in an overhead position without pre-setting a bridge frame, which greatly reduces the installation workload and saves the material cost of the bridge frame. During installation, first release the cable body as a whole and pre-place it on the ground at the installation location, and the two supporting parts 5 need to meet the vertical and parallel positions up and down. Then use the lifting equipment to lift the cable as a whole, and then fix it to the overhead frame after it reaches the set height. It should be noted that the lifting equipment includes but is not limited to cranes, hoists, lifting hoists, etc.

[0021] The outer side of the horizontal bending hinge 501 is provided with a heat shrink tubing 502; like Figure 2 As shown, by setting a heat shrink tube 502, the heat shrink tube 502 is sleeved on the outside of the horizontal bending hinge 501, and can shrink and deform after being heated, so that it can fit tightly on the outside of the horizontal bending hinge 501, thereby protecting the horizontal bending hinge 501. The heat shrink tube 502 has plasticity and will not affect the bending work of the horizontal bending hinge 501. In addition, it can also play a wear-resistant protection function to prevent the insulation layer 2 from being worn when the horizontal bending hinge 501 is frequently bent.

[0022] The horizontal bending hinge 501 includes a first square hinge 5011 located on the outside and a second square hinge 5012 located on the inside. Both the first square hinge 5011 and the second square hinge 5012 have hinge holes 5014 at their ends. Quick-release pins 5013 are located in the hinge holes 5014 and connect the first and second square hinges 5011 and 5012. like Figure 3 and Figure 4 As shown, by setting the first square hinge 5011 and the second square hinge 5012, the first square hinge 5011 and the second square hinge 5012 are connected in series end to end using a quick-release pin 5013, and the quick-release pin 5013 is set in a manner with its axial direction perpendicular to the ground, so that the first square hinge 5011 and the second square hinge 5012 can only bend on the horizontal plane and cannot be bent up and down, thereby achieving the purpose of supporting the cable body to remain horizontal, and the single section length of the first square hinge 5011 and the second square hinge 5012 is shorter, and the bending radius is shorter, which is suitable for cables with small mass and that need to be laid with frequent changes of direction.

[0023] The quick-release pin 5013 includes hinged sections 50131 corresponding to the hinged holes 5014. A locking section 50132 having a diameter smaller than the inner diameter of the hinged hole 5014 is disposed between the hinged sections 50131. An elastic clip 50134 is quickly connected to the outer side of the locking section 50132. A disassembly plate 50133 is disposed on the side of the elastic clip 50134. The elastic clip 50134 has an inner diameter consistent with that of the locking section 50132, and an outer diameter larger than that of the hinged hole 5014. like Figure 4 and Figure 5 As shown, by providing an elastic clamp 50134, the elastic clamp 50134 can be quickly connected with the locking section 50132 of the quick-release pin 5013, and its own outer diameter is larger than the hinge hole 5014. When the elastic clamp 50134 is clamped with the locking section 50132, the diameter of the middle section of the quick-release pin 5013 is larger than the hinge hole 5014, so that the quick-release pin 5013 is fixed. When the elastic clamp 50134 is separated from the locking section 50132, the diameter of the locking section 50132 is smaller than the inner diameter of the pin hole, so the quick-release pin 5013 can be pulled out. In this way, the first square hinge 5011 and the second square hinge 5012 can be quickly disassembled, so that the cable as a whole can be bent up and down when it needs to be bent up and down by disconnecting the horizontal bending hinge 501, allowing the cable as a whole to bend up and down according to laying requirements without affecting the integrity of the cable body. The opening size of the elastic clip 50134 is smaller than the diameter of the locking section 50132 and is elastic. By utilizing this design feature, the elastic clip 50134 will not slip off without external force after connection, thereby ensuring the stability of the connection between the first square hinge 5011 and the second square hinge 5012. Example 2

[0024] refer to Figure 6-10 The specific horizontal bending hinge 501 includes a first cylindrical hinge 5015 and a second cylindrical hinge 5017 connected in series at intervals. The end surface of the second cylindrical hinge 5017 is provided with a fixed pin 5016 rotatably connected to the first cylindrical hinge 5015; By setting a first cylindrical hinge 5015 and a second cylindrical hinge 5017, the first cylindrical hinge 5015 and the second cylindrical hinge 5017 are hinged by using a fixed pin shaft 5016 whose axis is perpendicular to the ground, so that the two can only bend in the horizontal plane, thereby supporting the cable body. The single body length of the first cylindrical hinge 5015 and the second cylindrical hinge 5017 is longer, and the number of interfaces within the same length is smaller, which correspondingly reduces the cumulative mechanical error of each section, and can better support the cable body horizontally, which is suitable for laying cables with heavier mass and larger turning radius.

[0025] A slot 5018 is formed at the tail end of the first cylindrical hinge 5015 , and a block 5019 is formed at the tail end of the second cylindrical hinge 5017 to be horizontally plugged into the slot 5018 ; like Figure 8 As shown, by setting the card slot 5018 and the card block 5019, the card slot 5018 can be horizontally inserted into the card slot 5018, so that the first cylindrical hinge 5015 and the second cylindrical hinge 5017 can be connected in series and are easy to disassemble, and the horizontal plug-in method is used to prevent the two from moving up and down, and thus will not be affected by the gravity of the cable. At the same time, the card connection method of the two can withstand greater tension and gravity. It should also be noted that after the heat shrink tube 502 shrinks, it can fit tightly with the first cylindrical hinge 5015 and the second cylindrical hinge 5017, which can limit the card block 5019 from sliding out of the card slot 5018.

[0026] A positioning frame 6 for fixing the position of the support component 5 is provided on the outside of the insulating layer 2. The positioning frame 6 includes a right semicircular clamp 601 and a left semicircular clamp 602. The upper and lower ends of the right semicircular clamp 601 and the left semicircular clamp 602 are provided with a clamping plate 605 that fits with the support component 5. The clamping plate 605 has an interference fit with the support component 5. like Figure 10 As shown, by setting the left semicircular card 602 and the right semicircular card 601, the left semicircular card 602 and the right semicircular card 601 can be attached to the outside of the insulating layer 2, and the two can be sleeved outside the insulating layer 2 after being combined, and a slot for fixing the support component 5 is formed at the upper and lower ends by using the card plate 605. The support component 5 can be positioned by using the card plate 605 so that the support component 5 can be arranged in a straight line outside the insulating layer 2, avoiding the problem of support failure of the support component 5 due to not being in the same straight line. The left semicircular card 602 and the right semicircular card 601 are set separately so that they can be sleeved outside the insulating layer 2 from both sides, avoiding the problem of cumbersome sleeve installation work due to the long cable.

[0027] The inner sides of the right semicircular card 601 and the left semicircular card 602 are provided with a self-adhesive surface 606 that adheres to the insulating layer 2. The two ends of the right semicircular card 601 and the left semicircular card 602 are respectively provided with a groove 603 and a protrusion 604 that are plugged into each other; like Figure 10 As shown, by providing the groove 603 and the protrusion 604, the protrusion 604 can be horizontally inserted into the groove 603, so that the right semicircular card 601 and the left semicircular card 602 can be accurately docked, ensuring that the positions of the card plates 605 on both sides correspond, thereby ensuring that the card plates 605 can be tightly clamped and fixed to the support component 5; In addition, self-adhesive surfaces 606 are provided on the inner sides of the right semicircular card 601 and the left semicircular card 602, so that both can be adhered to the outer side of the insulating layer 2, thereby forming a stable supporting and positioning structure.

[0028] The outer side of the protective layer 1 is provided with a mounting frame 8, which includes a right arc hoop 801 and a left arc hoop 802. The bottom ends of the right arc hoop 801 and the left arc hoop 802 are provided with a pin rod 803 hinged to each other. The top ends of the right arc hoop 801 and the left arc hoop are both provided with a through hole 806, and a bolt 805 is provided in the through hole 806. The outer sides of the right arc hoop 801 and the left arc hoop 802 are provided with a perforated ear plate 804 for installation and fixation; like Figure 9 As shown, by setting up a mounting frame 8, the mounting frame 8 is an external auxiliary mounting component, which consists of a left arc hoop 802 and a right arc hoop 801, both of which can rotate around the pin rod 803. After closing, they can be sleeved on the outside of the protective layer 1 and fixed with bolts 805, and the perforated ear plates 804 on the sides of the two can be connected to the overhead frame. The position of the perforated ear plates 804 in the accompanying drawings is only one embodiment of the present technical solution, and can be customized according to the installation position. For example, if the cable is fixed on the top plate, the perforated ear plates 804 can be customized on the upper part. If the cable is fixed on the wall, the perforated ear plates 804 can be customized on the side.

[0029] The outer side of the protective layer 1 is provided with a direction mark 7 for indicating a specific direction when the cable is installed; like Figure 1 As shown, by setting a direction mark 7, the arrows of the direction mark 7 point to the two support components 5 respectively and are perpendicular to the two support components 5. Its purpose is to identify the direction of the cable, that is, when the cable is installed, it is necessary to ensure that the indication along the direction mark 7 is perpendicular to the ground, thereby ensuring that the support component 5 can play the purpose of horizontal support. Example 3

[0030] The present invention also provides a method for manufacturing an overhead insulated power cable, comprising the following steps: S1. After assembling the horizontal bending hinge 501, wrap it with a heat shrink tubing 502 to form a supporting component 5. The conductive core 4, the core wrapping layer 3 and the insulating layer 2 are processed into a cable body using existing methods. S2. Fix the right semicircular card 601 and the left semicircular card 602 in the positioning frame 6 to the outside of the cable body using the self-adhesive surface 606, and then place the supporting component 5 in the card plate 605 of the positioning frame 6; S3. Finally, wrap the protective layer 1 around the outside of the cable body and the supporting component 5, and print the direction mark 7.

[0031] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
