Description
Technical Field
[0001] The present invention relates to the technical field of integrated protection of power transmission lines, and in particular to an integrated protection insulation device for power transmission lines. Background Art
[0002] Integrated protection for transmission lines is a comprehensive system project that aims to ensure the safe and stable operation of transmission lines and protect the safety of people and equipment. Installing insulating equipment on high-voltage transmission lines, such as insulators and insulating sleeves, can effectively isolate current and voltage and reduce the risk of electric shock and overvoltage. According to relevant standards and specifications, the safe distance between transmission lines and surrounding buildings, trees, construction machinery, etc. is clearly defined to reduce damage to cables caused by external impacts.
[0003] For example, the patent publication number published on the China Patent Network is: CN 217508143 U, and the patent name is: A power transmission line protection device, including a protection device body, an adjustment mechanism and a shock absorbing device, the top of the protection device body is provided with an adjustment mechanism, the outer side of the adjustment mechanism is provided with a shock absorbing device, and the shock absorbing device includes two side panels fixedly installed on the top of the protection device body. The power transmission line protection device, by providing an elastic ball in the shock absorbing device structure, can drive the first contact plate and the elastic ball to be in abutment state, and by the rebound effect of the elastic ball, the vibration force can be effectively buffered to avoid the possibility of damage to the transmission line due to the influence of the vibration force, and by providing a spring and a slide groove in the adjustment mechanism, it is convenient to adjust the support position of the protective shell, so that it is suitable for transmission lines of different diameters, so that the overall purpose of having a good protection effect on the transmission line is achieved, thereby reducing the maintenance cost of the transmission line.
[0004] However, the assembly and decoration of existing protective devices are relatively simple, mainly by clamping multiple transmission lines to squeeze and contact each other inside. When multiple transmission lines are in contact or close to each other, the electromagnetic environment will become more complicated, increasing electromagnetic interference and electromagnetic radiation, and having adverse effects on surrounding electronic equipment and human health.
[0005] At the same time, the contact or close distance between transmission lines may lead to insufficient electrical clearance, increase the risk of short circuit and flashover, which will not only damage power equipment, but also cause fire or electric shock accidents, posing a threat to personnel safety.
[0006] In addition, when multiple transmission lines are in contact with each other or closely arranged, a fault in one line may affect other lines. For example, faults such as short circuits or flashovers may spread to other lines through electromagnetic induction or contact conduction, leading to a greater risk of power outages.
[0007] Therefore, it is necessary to redesign the integrated protective insulation device of the transmission line. Summary of the invention

The transmission structure 5 can drive the opening and closing structure 4 to move and achieve a self-positioning effect on the adjusted opening and closing structure 4. Support structures 6 are provided on both sides of the support frame 2 and are located outside the opening and closing structure 4. The support structure 6 can move synchronously during the movement of the opening and closing structure 4. The support structure 6 can provide auxiliary support to the transmission cable 1 after the movement is completed, thereby increasing the contact area between the transmission cable 1 and the positioning structure 3.
[0045] refer to Figure 5 The support frame 2 includes a sleeve 7 arranged on the inner side of the transmission cable 1. The sleeve 7 is made of high-strength, corrosion-resistant material. A plurality of openings 8 are provided on the surface of the sleeve 7. The interior of the sleeve 7 is arranged to be hollow. Sealing edges 9 are provided on both sides of the sleeve 7. The positioning structure 3 is arranged on the outer surface of the sleeve 7, and the transmission structure 5 is located inside the sleeve 7.
[0046] As a technical optimization solution of the present invention, the bearing frame 2 adopts a sleeve 7 structure. The internal hollow design facilitates the installation of the transmission structure 5. The opening 8 on the surface facilitates interaction with the external environment. The setting of the edge sealing 9 enhances the stability of the structure, making the bearing frame 2 both light and strong, and able to effectively support and protect the transmission cable 1.
[0047] refer to Figure 5The positioning structure 3 includes a connecting block 10 arranged on the outside of the sleeve 7 and spaced apart from the opening 8. The inner side of the connecting block 10 is movably connected to a shaft 11 through a bearing. A shielding frame 12 is fixedly connected to the surface of the shaft 11. The shielding frame 12 extends to the outside of the power transmission cable 1 from a side away from the shaft 11. The shielding frames 12 are symmetrically arranged and form a closed loop wrapped around the surface of the transmission cable when in contact. The opening and closing structure 4 can use the shaft 11 to drive the shielding frame 12 to swing toward each other.
[0048] As a technical optimization solution of the present invention, by setting the connecting block 10, the shaft rod 11 and the shielding frame 12, independent connection and shielding protection of the transmission cable 1 are achieved. The symmetrical setting of the shielding frame 12 and the formation of a closed loop effectively prevent the external environment from damaging the transmission cable 1, thereby improving the safety and service life of the cable.
[0049] refer to Figure 8 The opening and closing structure 4 includes a load-bearing ring 13 arranged on both sides of the sleeve 7, and a plurality of extrusion frames 14 are fixedly connected to the outside of the load-bearing ring 13. The side of the extrusion frame 14 away from the load-bearing ring 13 is set to a cone shape. Both ends of the shaft 11 penetrate the outside of the connecting block 10 and are fixedly connected with a force-bearing rod 15. The side of the force-bearing rod 15 away from the shaft 11 extends to the outside of the extrusion frame 14. In the process of the transmission structure 5 driving the load-bearing ring 13 to move toward each other, the extrusion frame 14 on the surface of the load-bearing ring 13 can be used to squeeze the force-bearing rod 15, so that the force-bearing rod 15 drives the shielding frame 12 to swing inward by the shaft 11. The side of the force-bearing rod 15 away from the shaft 11 is movably connected to a roller 30 through a pin shaft, and the outer surface of the roller 30 contacts the outer surface of the extrusion frame 14. When working, the load-bearing ring 13 is arranged on both sides of the sleeve 7 and is relatively The transmission structure 5 is in a static or preset initial position. When the transmission structure 5 starts to work, the transmission structure 5 drives the load-bearing ring 13 to move toward each other. As the load-bearing ring 13 moves toward each other, the conical design of the extrusion frame 14 makes it gradually approach the force-bearing rod 15. Due to the guiding effect of the cone, the extrusion frame 14 generates an outward extrusion force on the force-bearing rod 15. After being extruded by the extrusion frame 14, the force-bearing rod 15 rotates through the shaft 11, driving the side away from the shaft 11, i.e., the side where the roller 30 is located, to swing inward. During the process of the force-bearing rod 15 swinging inward, the outer surface of the roller 30 keeps in contact with the outer surface of the extrusion frame 14 and rolls. This rolling helps to reduce friction and makes the movement of the force-bearing rod 15 smoother. The roller 30 may also play a role in auxiliary positioning to ensure that the force-bearing rod 15 maintains the correct direction and position during the movement.
[0050] As a technical optimization solution of the present invention, by setting a load-bearing ring 13, an extrusion frame 14, a force-bearing rod 15 and an axial rod 11, a synchronous clamping connection of multiple positioning structures 3 shielding frames 12 is achieved, which simplifies the operation process, improves work efficiency, and ensures the firmness and reliability of the clamping.

During the rotation of the bidirectional screw 16 carrying the bidirectional screw 16, the rotating wheel 17 can use the thread to push the carrying ring 13 to move toward each other.
[0052] As a technical optimization solution of the present invention, by setting a bidirectional screw 16 and a rotating wheel 17 and using the thread to push the supporting ring 13 to move toward each other, thereby driving the opening and closing structure 4 to work, it can have the advantages of simple structure, high transmission efficiency, good self-positioning effect, etc., ensuring the stable operation and precise control of the device.
[0053] refer to Figure 4 The support structure 6 includes a bracket 18 fixedly connected to both sides of the outer surface of the sleeve 7, and a rocker arm 19 is movably connected to the inner side of the bracket 18 through a pin shaft. A support frame 20 is fixedly connected to the side of the rocker arm 19 away from the bracket 18, and an insulating material 21 is fixedly connected to the outer surface of the support frame 20. The side of the support frame 20 away from the rocker arm 19 is wrapped around the surface of the power transmission cable 1. A linkage structure 22 is provided on the surface of the rocker arm 19. The linkage structure 22 can start the rocker arm 19 to swing during the continuous movement of the opening and closing structure 4. A spring plate 31 is fixedly connected to the outer side of the force-bearing rod 15, and the side of the spring plate 31 away from the force-bearing rod 15 contacts with the surface of the bracket 18. The spring plate 31 is elastic. When the extrusion frame 14 is out of contact with the force-bearing rod 15, the spring plate 31 can use its elasticity to push the force-bearing rod 15 to reset and swing.
[0054] As a technical optimization solution of the present invention, by setting the bracket 18, the rocker arm 19, the support frame 20 and the linkage structure 22, the synchronous movement of the opening and closing structure 4 and the auxiliary support of the transmission cable 1 are realized during the movement, the contact area between the transmission cable 1 and the positioning structure 3 is increased, the protection effect is improved, and the stability and bearing capacity of the entire device are also enhanced.
[0055] refer to Figure 4 The linkage structure 22 includes a push plate 23 fixedly connected to the side of the rocker arm 19 close to the bracket 18. The push plate 23 extends to the outside of the extrusion frame 14 away from the side of the rocker arm 19. The outside of the extrusion frame 14 can contact the inside of the push plate 23 during the movement and push the push plate 23 to swing.
[0056] As a technical optimization solution of the present invention, by setting the interaction between the push plate 23 and the extrusion frame 14, the rocker arm 19 is automatically started to swing during the movement of the opening and closing structure 4, so that the movement of the supporting structure 6 is synchronized with the movement of the opening and closing structure 4, thereby improving the overall coordination and working efficiency of the device.

When the sleeve plate 24 swings with the rocker arm 19, the slide rod 26 can be used to squeeze the shift fork 25 so that it is inserted into the surface of the shielding frame 12.
[0058] As a technical optimization solution of the present invention, by setting the shift fork 25 and the sleeve plate 24, the shift fork 25 can be inserted into the surface of the shielding frame 12 during the swinging of the rocker arm 19, thereby further stabilizing the position of the shielding frame 12 and preventing the two shielding frames 12 from displacement and separation.

The carrying ring 13 is sleeved on the surface of the limiting strip 29 and is slidably connected to the limiting strip 29 .
[0062] As a technical optimization solution of the present invention, by setting the limit strip 29, the load-bearing ring 13 can slide more smoothly and accurately inside the sleeve 7, thereby avoiding the load-bearing ring 13 from shifting or shaking during the movement, ensuring the transmission accuracy and stability of the transmission structure 5, and ensuring the normal operation of the device.
[0063] The working principle and use process of the present invention are as follows: First, the device is installed on the inner side of the transmission cable 1, and its main body is a carrier frame 2 in the shape of a sleeve 7. The surface of the sleeve 7 is provided with a plurality of openings 8 to facilitate the operation of the internal structure and the interaction with the external environment. The interior of the sleeve 7 is hollow, and sealing edges 9 are provided on both sides to fix and protect the internal structure. On the outer surface of the sleeve 7, a series of connecting blocks 10 arranged at intervals with the openings 8 are provided. These connecting blocks 10 are movably connected to the shaft 11 through bearings, and a shielding frame 12 is fixed on the shaft 11. The shielding frame 12 extends from the side of the shaft 11 away from the shaft 11 to the outside of the transmission cable 1. The shielding frames 12 are symmetrically arranged. When they contact each other, they can form a closed loop wrapped around the surface of the transmission cable 1, thereby providing shielding protection. Inside the sleeve 7, there are supporting rings 13 on both sides, and a conical extrusion frame 14 is fixed to the outside of the supporting ring 13. Both ends of the shaft 11 pass through the connecting block 10 and are fixedly connected to the force-bearing rod 15, and the force-bearing rod 15 extends to the outside of the extrusion frame 14. At this time, the device is in the initial state, and the shielding frame 12 may be in an open state and is not in close contact with the power transmission cable 1. In order to activate the protection function, the operator will rotate the rotating wheel 17 located outside the sleeve 7 and exposed through the opening 8. The rotating wheel 17 is fixedly connected to the bidirectional screw 16 inside the sleeve 7. Both ends of the bidirectional screw 16 pass through the supporting ring 13 and the edge sealing 9, and are movably connected to the edge sealing 9 through bearings. When the rotating wheel 17 rotates, the bidirectional screw 16 rotates accordingly, and uses its thread to push the supporting rings on both sides. 13 move toward each other. As the carrying ring 13 moves toward each other, the conical extrusion frame 14 on its outer side gradually approaches the force-bearing rod 15. Due to the conical design of the extrusion frame 14, they will gradually apply pressure to the force-bearing rod 15, so that the force-bearing rod 15 is squeezed and moves along the direction of the shaft 11. This movement causes the shaft 11 to drive the shielding frame 12 to swing inward until the shielding frame 12 is tightly wrapped around the surface of the transmission cable 1 to form a closed loop, thereby achieving shielding and protection for the transmission cable 1. During the movement of the opening and closing structure 4, the linkage of the supporting structure 6 is also triggered. The swing rod 19 on the inner side of the bracket 18 is movably connected to the push plate 23 by a pin shaft, and a push plate 23 is fixed on its surface. When the extrusion frame 14 moves and contacts the push plate 23, it will push the push plate 23 to swing, thereby driving the swing rod 19 and the support frame 20 fixed thereon move toward the direction of the transmission cable 1. The outer surface of the support frame 20 is covered with an insulating material 21. When they move to the surface of the transmission cable 1, they can provide additional support, increase the contact area between the transmission cable 1 and the positioning structure 3, and improve the protection effect. In addition, the outer side of the swing rod 19 is also fixedly connected to a sleeve plate 24 through a pin shaft. The fork 25 on the inner side of the sleeve plate 24 will be squeezed by the slide bar 26 during the swinging process of the sleeve plate 24, so that it is plugged into the surface of the shielding frame 12, further stabilizing the position of the shielding frame 12. At the same time, the guide rod 28 on the outer side of the fork 25 passes through the vertical plate 27 and is slidably connected to the vertical plate 27, providing guidance and support for the movement of the fork 25. In the whole working process, the transmission structure 5 drives the opening and closing structure 4 to move.Then, the positioning structure 3 is driven to close through the shaft 11 and the force-bearing rod 15, and the linkage of the supporting structure 6 is triggered at the same time, so as to realize comprehensive protection and support of the transmission cable 1 and avoid contact between adjacent transmission cables 1.
[0064] In summary: the integrated protective insulation device for the transmission line realizes independent connection and all-round shielding protection of the transmission cable 1 through the design of the positioning structure 3 and the shielding frame 12, effectively preventing the external environment from infringing the transmission cable 1, such as wind, rain, dust, animal bites, etc., and improving the safety and service life of the cable. The support frame 2 adopts a sleeve 7 structure, and the internal hollow design facilitates the installation of the transmission structure 5 and the support structure 6, while reducing the overall weight, making the device compact and easy to install and disassemble.
