[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 7 , the interphase spacer opening and closing hook-type lifting automatic tightening mechanism includes an interphase spacer 4, the outer wall of the interphase spacer 4 is symmetrically fixed with an anti-slip ring 41, the anti-slip ring 41 is composed of three discs and the diameter of the discs at both ends is larger than the diameter of the central disc, the interphase spacer 4 is a long round rod and is made of insulating material, the interphase spacer 4 is used to fix the spacing between the wires to prevent the wires from whipping each other, suppressing breeze vibration and sub-spacing oscillation. At the same time, by installing anti-slip rings 41 on the interphase spacer 4, when the device is lifted by a drone, the connection part with the interphase spacer 4 is prevented from sliding, and the device is prevented from tilting when it is lifted. The two anti-slip rings 41 are respectively connected to the control servo 5 by ropes. The control servo 5 has an existing device for releasing the rope connected to the anti-slip ring 41 to achieve the effect of disengaging from the anti-slip ring 41. I will not go into details here. The left and right ends of the interphase spacer rod 4 are respectively fixed with hooks 1, and the lower ends of the hooks 1 are respectively provided with symmetrical clamping blocks 2. The opposite ends of the two hooks 1 are respectively provided with electric push rods 3 connected to the clamping blocks 2, and the electric push rods 3 are fixed on the hook 1. The electric push rods 3 are extended and retracted to push the clamping blocks 2 to clamp the wires, thereby fixing the ropes, preventing the wires from whipping each other, and effectively suppressing breeze vibration and sub-span oscillation. The hook 1 is L-shaped and has a bend at one end. One of the two clamping blocks 2 is fixedly connected to the hook 1, and a connecting block 21 is fixed at one end of the other clamping block 2. The connecting block 21 is fixedly connected to the telescopic cylinder 36. The L-shaped hook 1 has a downward bend at one end to facilitate the fixing of the clamping block 2. At the same time, the opposite ends of the two clamping blocks 2 are provided with an arc groove, which is convenient for clamping the wire in the arc groove to prevent the wire from detaching.

[0027] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The electric push rod 3 includes a front plate 31 and a rear plate 32. The end of the front plate 31 away from the rear plate 32 is provided with a plurality of pillars. The front plate 31 is fixed on the hook 1. The rear plate 32 is used to fix the motor 33 and the fixed cylinder 34. The motor 33 and the fixed cylinder 34 are fixed between the front plate 31 and the rear plate 32. The output end of the motor 33 is fixedly connected to a gear 331. The right end of the fixed cylinder 34 is threadedly connected to a transmission cylinder 35. The outer wall of the transmission cylinder 35 is provided with a plurality of tooth grooves 351 along its circumference. The gear 331 rotates and engages with the tooth grooves 351 to drive the transmission cylinder 35 to rotate. The transmission cylinder 35 is threadedly engaged with the fixed cylinder 34. The transmission cylinder 35 is moved from the fixed cylinder 34 The gear 331 is meshed with the gear 331 through the gear groove 351, and the motor 33 provides power to drive the gear 331 to rotate. At the same time, the gear 331 and the transmission cylinder 35 are transmitted, and the transmission cylinder 35 is threadedly connected to the fixed cylinder 34 and the telescopic cylinder 36. The telescopic cylinder 36 is slidably connected to the fixed rod 341. The transmission cylinder 35 rotates to make the transmission cylinder 35 and the telescopic cylinder 36 move synchronously, pushing the clamping block 2 to clamp the wire, achieving a larger stroke ratio, simple structure, high reliability, and small size. The right end of the transmission cylinder 35 is threadedly connected to the telescopic cylinder 36, and the right end of the telescopic cylinder 36 is connected to the clamping block 2. When the transmission cylinder 35 rotates and extends from the inside of the fixed cylinder 34, it drives the telescopic cylinder 36 to extend. At the same time, the transmission cylinder 35 is threadedly connected to the telescopic cylinder 36. Since the slide groove 361 is engaged with the guide bar 342, the fixed cylinder 34 cannot rotate, and the telescopic cylinder 36 is extended from the inside of the transmission cylinder 35, achieving the effect of synchronous extension of the transmission cylinder 35 and the telescopic cylinder 36, and achieving a larger stroke ratio. A fixed rod 341 is fixed to the inside of the fixed cylinder 34, and the telescopic cylinder 36 is slidably connected to the fixed rod 341. The outer wall of the fixed rod 341 is symmetrically provided with a guide bar 342. A tooth groove 351 is opened on the outer wall of the transmission cylinder 35, and the depth of the tooth groove 351 is greater than the screw thread on the outer wall of the transmission cylinder 35. The pattern ensures that when the gear 331 is engaged with the tooth groove 351, it does not affect the threaded connection between the telescopic cylinder 36 and the transmission cylinder 35. The corresponding connection between the slide groove 361 and the guide bar 342 prevents the telescopic cylinder 36 from rotating, so that the telescopic cylinder 36 and the transmission cylinder 35 are extended synchronously. The inner wall of the telescopic cylinder 36 is symmetrically provided with a slide groove 361. The telescopic cylinder 36 is slidably connected to the fixed rod 341 through the slide groove 361 and the guide bar 342. The transmission cylinder 35 is located inside the fixed cylinder 34, and the telescopic cylinder 36 is located inside the transmission cylinder 35. The outer surface of the transmission cylinder 35 is threadedly connected to the inner surface of the fixed cylinder 34, and the outer surface of the telescopic cylinder 36 is threadedly connected to the inner surface of the transmission cylinder 35.

[0028] When using this utility model:

[0029] First, the drone is used to control the servo 5 and lift the device to the specified position. Then, the clamping block 2 on the hook 1 is brought into contact with the wire. Next, the electric push rod 3 is controlled to work so that the clamping block 2 clamps and fixes the wire. During the operation of the electric push rod 3, the gear 331 rotates and engages with the tooth groove 351 to drive the transmission cylinder 35 to rotate. The transmission cylinder 35 is threadedly engaged with the fixed cylinder 34. The transmission cylinder 35 extends from the inside of the fixed cylinder 34. When the transmission cylinder 35 rotates and extends from the inside of the fixed cylinder 34, it will drive the telescopic cylinder 36 to extend. At the same time, the transmission cylinder 35 is threadedly connected to the telescopic cylinder 36. Since the slide groove 361 is engaged with the guide bar 342, the fixed cylinder 34 cannot rotate, and the telescopic cylinder 36 is extended from the inside of the transmission cylinder 35. Finally, by controlling the servo 5 to contact and fix the rope connected to the anti-slip ring 41, the disengagement effect is achieved, thereby achieving the spacing of the wires.
