Fig.19 As shown in the figure, the intermediate rotating member 21 is driven to rotate clockwise by the installation shaft 13, so that the active base member 18 and the intermediate rotating member 21 rotate relative to each other, and at the same time, the intermediate rotating member 21 drives the rotating long rod 31 connected to the intermediate rotating member 21 to rotate clockwise, and due to the linear guidance of the four guide slots 20, the active rotating member 10 is extended to limit the high-voltage cables 43 located in the two equipment installation rooms 8. At the same time, as shown in the attached figure Fig.24 As shown, the active rotating member 10 extends toward the auxiliary rotating wheel 9, and pushes the high-voltage cable 43 between the two toward the auxiliary rotating wheel 9, so that an inclination angle is generated between the high-voltage cable 43 located at the front end of the tower body 1 and the conveying rotating wheel 3, so as to prevent the high-voltage cable 43 located at the front end of the tower body 1 from contacting the front end of the tower body 1; and when the mounting shaft 13 is connected to the active base member 18 and the intermediate rotating member 21, the active base member 18 and the intermediate rotating member 21 cannot rotate relative to each other, so that the position of one end of the rotating long rod 31 connected to the intermediate rotating member 21 is fixed, thereby fixing the position of the active rotating member 10, and making the four active rotating members 10 and one active base member 18 rotate together; And can be attached Fig.24 The front end is equipped with a wire release device. Fig.24 A winding device is provided at the rear end, and the unwinding device and the winding device perform unwinding or winding operations through a rotating reel, and can also be used in the adjacent Fig.24A fixed rotating wheel and an adjustable rotating wheel with adjustable diameter are fixedly arranged at the rear end, and the diameter of the adjusting rotating wheel can be adjusted by the active rotating member 10, that is, the circular member is driven to rotate by the rotation of the shaft body, and an adjusting component is arranged in the adjusting rotating wheel through a linear slide groove, and the circular member drives the adjusting component to move linearly through a deflection rod to adjust the diameter of the adjusting wheel to the adjacent Fig.24 The rear high-voltage cable 43 is limited, and then the shaft is locked, so that the high-voltage cable 43 slides and rubs between the fixed rotating wheel and the adjusting rotating wheel to slow down the downward movement of the high-voltage cable 43 .

[0024] The present invention can be explained by the following operation mode: First, one end of the high-voltage cable 43 is passed through an auxiliary rotating wheel 9 and four active rotating parts 10, and the high-voltage cable 43 is pulled upward to place the high-voltage cable 43 on the upper end of a group of conveying rotating wheels 3, as shown in the attached figure. Fig.24 As shown, one end of the high-voltage cable 43 is located at the rear end of the tower body 1, and at the same time, the end of the high-voltage cable 43 located at the rear end of the tower body 1 is connected to the winding device, and the end of the high-voltage cable 43 located at the front end of the tower body 1 is connected to the unwinding device, so as to facilitate the subsequent tightening operation; then the installation shaft 13 is pushed to move toward the inner center of the installation base frame 7 until the first magnet 26 and the second magnet 28 are against each other and attracted by opposite poles, as shown in the attached figure. Figure 6 , Attachment Figure 7 and attached Figure 8 As shown, at this time, the limiting disc 27 abuts against the inner wall of the movable chamber 22 on one side of the second through hole 25, and the push long plate 17 is pulled to make the push long plate 17 abut against the first limiting plate 14, and then the bolts are screwed into the threaded holes of the limiting slide rail 16 and the threaded holes of the push long plate 17 to lock the position of the push long plate 17, and the push long plate 17 prevents the installation shaft 13 from moving toward the outside of the installation base frame 7, so that the installation shaft 13 is connected to the intermediate rotating member 21; Then, the intermediate rotating member 21 is rotated by rotating the rotating shaft 13. Fig. 9 and attached Fig.19 As shown, when the intermediate rotating member 21 rotates clockwise, the intermediate rotating member 21 drives the ends of the four rotating long rods 31 connected to the intermediate rotating member 21 to rotate clockwise, and the ends of the four rotating long rods 31 connected to the active rotating member 10 move away from the intermediate rotating member 21, thereby allowing the four active rotating members 10 to move away from the intermediate rotating member 21 to perform an extension movement, and the two sides of the high-voltage cables 43 located in the two equipment installation rooms 8 are abutted by the auxiliary rotating wheels 9 and the active rotating member 10 to limit the high-voltage cables 43; Then, the installation shaft 13 is pulled to move toward the outside of the installation base frame 7 until the third magnet 29 and the fourth magnet 33 abut against each other and attract each other with opposite poles. Fig.21 , Attachment Fig. 22 and attached Fig.23As shown, at this time, the limiting disc 27 abuts against the inner wall of the active chamber 22 on one side of the first through hole 24, and the long push plate 17 is unlocked and pulled to make the long push plate 17 abut against the second limiting plate 15, and then the bolts are screwed into the threaded holes of the limiting slide rail 16 and the threaded holes of the long push plate 17 to lock the position of the long push plate 17, and the long push plate 17 is used to prevent the installation shaft 13 from moving toward the inside of the installation base frame 7, so that the installation shaft 13 is connected to the active base member 18 and the intermediate transfer member 21; When the high voltage cable 43 is being laid out, Fig.24 As shown, the wire-releasing device and the wire-winding device are started, and the wire-releasing movement of the wire-releasing device allows the high-voltage cable 43 at the front end of the tower body 1 to move toward the adjacent Fig.24 The tower body 1 moves to the right, and the winding movement of the winding device allows the high-voltage cable 43 at the rear end of the tower body 1 to move to the adjacent Fig.24 The high-voltage cables 43 located in the two equipment installation rooms 8 move upward, and the upwardly moving high-voltage cables 43 push the four active rotating parts 10 to rotate, as shown in the attached figure. Fig.19 As shown in the figure, the four active rotating parts 10 and the active base part 18 are rotated clockwise, and as shown in the figure Fig.11 and attached Fig.14 As shown, the active base member 18 allows the rotating ratchet 37 to rotate clockwise through the annular connecting member 36; When the rotating ratchet 37 rotates clockwise, the teeth of the rotating ratchet 37 adjacent to the pawl rod 40 push the pawl rod 40 to deflect upward, so that the pawl rod 40 is away from the rotating ratchet 37, and the rotating ratchet 37 is rotated by a certain angle. At the same time, under the elastic force of the reset torsion spring 41, the pawl rod 40 is deflected downward, so that the pawl rod 40 is located in the tooth groove of the rotating ratchet 37 and the rotating ratchet 37 is prevented from rotating. Then, the rotating ratchet 37 is driven to rotate clockwise, so that the rotating ratchet 37 and the four active rotating parts 10 are intermittently rotated clockwise. The ratchet wheel 37 is rotated to drive the first gear 38 to rotate intermittently clockwise, and the first gear 38 is meshed with the second gear 42 to drive the second gear 42 to drive the auxiliary rotating wheel 9 to rotate intermittently counterclockwise through the rotating shaft 11, and the rotation tangential driving force of the auxiliary rotating wheel 9 and the four active rotating parts 10 close to the side of the high-voltage cable 43 is in the upward direction, so that the auxiliary rotating wheel 9 and the four active rotating parts 10 intermittently push the high-voltage cable 43 upward to accelerate the upward movement of the end of the high-voltage cable 43; When tightening the high voltage cable 43, Fig.25 As shown, the winding movement of the wire-releasing device allows the high-voltage cable 43 at the front end of the tower body 1 to move toward the adjacent Fig.25 The tower body 1 moves to the left, and the winding movement of the winding device allows the high-voltage cable 43 at the rear end of the tower body 1 to move to the adjacent Fig.25The high-voltage cables 43 located in the two equipment installation rooms 8 move downward, and the high-voltage cables 43 moving downward push the four active rotating parts 10 to rotate, as shown in the attached figure. Fig.19 As shown in the figure, the four active rotating parts 10 and the active base part 18 are rotated counterclockwise, and as shown in the attached Fig.11 and attached Fig.14 As shown, the active base member 18 allows the rotating ratchet 37 to rotate counterclockwise through the annular connecting member 36; When the rotating ratchet 37 rotates counterclockwise, the pawl rod 40 is stuck in the tooth groove of the rotating ratchet 37, and the rotating ratchet 37, the first gear 38 and the four active rotating parts 10 stop rotating. Since the first gear 38 is meshed with the second gear 42 to stop the second gear 42 and the auxiliary wheel 9 from rotating, the high-voltage cables 43 in the two equipment installation rooms 8 are transformed from rolling friction to sliding friction, and the friction force of one end of the high-voltage cable 43 in the two equipment installation rooms 8 is increased to slow down the downward movement of that end of the high-voltage cable 43.
