They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, a power distribution network frame for power distribution network planning includes a pole 1. A fixing mechanism is provided at the top of the pole 1. The fixing mechanism includes a top box 201, which is fixedly connected to the top of the pole 1. Two sliders 203 are slidably connected to the inner surface of the top box 201. A transmission mechanism is provided inside the top box 201. The transmission mechanism includes a connecting shaft 403, which is rotatably connected to the top box 201. A gear 404 is fixedly connected to the connecting shaft 403. A synchronization mechanism is provided inside the top box 201. The synchronization mechanism includes two worm gears 501, which are fixedly connected to the front and rear ends of the connecting shaft 403. The bottom of the worm gears 501 is engaged with a worm gear. A limiting shaft 503 is fixedly connected to the wheel 502 and the worm gear 502. A timing belt 504 is connected to the limiting shaft 503. When the gear 404 rotates, it will also drive the connecting shaft 403 to rotate. The rotation of the connecting shaft 403 will drive the worm gears 501 on the front and rear sides to rotate. The rotation of the worm gears 501 will drive the worm wheel 502 below to rotate. The rotation of the worm wheel 502 will drive the two timing belts 504 to rotate. A lifting mechanism is provided inside the rod body 1. Sliding mechanisms are provided on both sides of the top box 201. An auxiliary mechanism is provided on the rod body 1. A mounting plate 9 is fixedly connected to the bottom of the rod body 1. Several reinforcing ribs 8 are fixedly connected to the mounting plate 9. The reinforcing ribs 8 are fixedly connected to the rod body 1.

[0027] The fixing mechanism includes several extension blocks 202, which are fixedly connected to both sides of the top box 201.

[0028] The sliding mechanism includes two circular grooves 301. The circular grooves 301 are located on the side of the slider 203 away from the center of the top box 201. A ball 302 is rotatably connected to the inner surface of the circular grooves 301. A connecting rod 303 is fixedly connected to the side of the ball 302 away from the center of the top box 201. A crossarm 304 is fixedly connected to the other end of the connecting rod 303. Several insulators 305 are fixedly connected to the crossarm 304. When encountering strong winds, the cable will be affected by the wind and sway. Since the length of the cable is fixed, the cable will pull the insulators 305. The force on the insulators 305 will pull the slider 203 through the connecting rod 303 and the crossarm 304. Since the wind will cause the cable to dance, its pulling direction is not fixed. Therefore, when the crossarm 304 is under force, the ball 302 will rotate on the inner surface of the circular grooves 301.

[0029] The transmission mechanism includes two racks 401, which are fixedly connected to the side of the slider 203 near the center of the top box 201. Several springs 402 are fixedly connected to the slider 203, and the other end of the springs 402 is fixedly connected to the top box 201. When the slider 203 slides, it will drive the racks 401 to slide. The sliding of the racks 401 will drive the gear 404 to rotate. The rotation of the gear 404 will drive the other rack 401 to slide, so that the slider 203 on the other side will also slide away from the center of the top box 201. When the slider 203 slides, it will compress the springs 402 to ensure that the tension generated by the cable will be absorbed by the springs 402 when encountering strong winds, so as to avoid the cable being directly subjected to the force on the top of the rod 1 and causing it to deform, thereby enhancing its service life.

[0030] The lifting mechanism includes a take-up roller 601, which is connected to the bottom end of the synchronous belt 504. A rope is fixedly connected to the take-up roller 601. The take-up roller 601 is rotatably connected to the inner wall of the rod 1. A connecting plate 602 is suspended at the bottom of the take-up roller 601, and a counterweight 603 is suspended at the bottom of the connecting plate 602. When the synchronous belt 504 rotates, it will drive the take-up roller 601 to rotate and release the rope. The rotation of the take-up roller 601 will cause the connecting plate 602 to descend through the rope, thereby lowering the height of the counterweight 603. The lowering of the height of the counterweight 603 will lower the center of gravity of the device, thereby preventing the rod 1 from bending or tipping over due to strong winds and enhancing safety.

[0031] The auxiliary mechanism includes a rotating shaft 701, which is rotatably connected to the top of the top box 201. Several wind cups 702 are fixedly connected to the top of the rotating shaft 701. A lightning rod 703 is fixedly connected to the top of the top box 201. A grounding pin 704 is fixedly connected to the bottom of the mounting plate 9. The wind force will cause the wind cups 702 to rotate, which makes it convenient for operators to observe the wind force. When encountering thunderstorms, the lightning rod 703 can prevent the main body of the device from being struck by lightning and guide the lightning to the ground through the grounding pin 704.

[0032] Working principle: When using this device, the operator first fixes the device to the designated position through the mounting plate 9, and then fixes the cable to the insulator 305.

[0033] When the device encounters strong winds, the cable will sway due to the wind. Since the cable length is fixed, the cable will pull on the insulator 305. The force on the insulator 305 will pull the slider 203 through the connecting rod 303 and the crossarm 304. Because the wind force will cause the cable to gallop, and its pulling direction is not fixed, when the crossarm 304 is under force, the ball 302 will rotate on the inner surface of the circular groove 301 to accommodate the cable's galloping and cause the slider 203 to slide away from the center of the top box 201. At the same time, it will drive the rack 401 to slide. The sliding of the rack 401 will drive the gear 404 to rotate. The rotation of the gear 404 will drive the other rack 401 to slide, causing the slider 203 on the other side to slide away from the center of the top box 201. While the slider 203 is sliding, the spring 402 will be compressed to ensure that the tension generated by the cable will be absorbed by the spring 402 in windy weather, and the slider 203 on the other side will be released, so as to avoid the cable being directly subjected to the force on the top of the rod 1 and causing it to deform, thus enhancing its service life.

[0034] When gear 404 rotates, it also drives connecting shaft 403 to rotate. The rotation of connecting shaft 403 drives the worm gears 501 on both sides to rotate. The rotation of worm gears 501 drives the worm wheel 502 below to rotate. The rotation of worm wheel 502 drives the two synchronous belts 504 to rotate. The rotation of synchronous belts 504 drives take-up roller 601 to rotate and release rope. The rotation of take-up roller 601 causes connecting plate 602 to descend through the rope, thus lowering the height of counterweight 603. The lowering of the height of counterweight 603 lowers the center of gravity of the device, thereby preventing the rod 1 from bending or tipping over due to strong winds and enhancing safety.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
