[0024] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0025] A cable fixing device for an electric power tower, referring to Figure 1 , including an iron tower 1, the outer end of the iron tower 1 is connected to a connecting box 2 by bolts, and also includes a connecting mechanism 3 arranged at the bottom end of the connecting box 2, the bottom end of the connecting mechanism 3 is connected to a fixing mechanism 4, and a cable is connected and installed in the fixing mechanism 4.

[0026] Reference Figure 2-Figure 4 The connecting mechanism 3 includes a connecting main rod 31, an insulating terminal 32, a buffer box 33, a middle end mechanism 34 and a connecting sub-rod 35. The top of the connecting main rod 31 is fixedly connected to the middle end of the bottom of the connecting box 2. The outer top of the connecting main rod 31 is fixedly connected to the insulating terminal 32, which can improve the safety of the cable. The bottom end of the connecting main rod 31 is movably connected to the buffer box 33. The outer middle end of the connecting main rod 31 is connected to the middle end mechanism 34. The outer side of the middle end mechanism 34 is fixedly connected with no less than two groups of connecting sub-rods 35 at equal intervals, and is connected to the top surface of the buffer box 33 through the connecting sub-rod 35. The bottom end of the connecting sub-rod 35 is fixedly connected to the top surface of the buffer box 33, which can improve the connection stability between the connecting main rod 31 and the buffer box 33. The bottom end of the buffer box 33 is connected to the fixing mechanism 4. The bottom end of the connecting rod 31 extends through the buffer box 33 and is fixedly connected to a bottom plate 311. A groove 312 is formed at the middle end of the bottom of the bottom plate 311. The bottom plate 311 is a regular polygon with at least three sides. It should be noted that the number of sides of the bottom plate 311 can be set according to the use environment and use requirements, and is not limited here; The buffer box 33 has a buffer cavity 331 at its inner end. At least two sets of curved plates 332 are fixedly connected to the inner side of the buffer cavity 331. A coil spring 333 corresponding to the groove 312 is installed at the middle end of the inner bottom of the buffer cavity 331. The number and position of the curved plates 332 correspond to the number of sides of the bottom plate 311 and can contact the outer side of the bottom plate 311. Furthermore, an opening corresponding to the connecting rod 31 is provided at the top end of the buffer cavity 331. The diameter of the opening is larger than that of the connecting rod 31, and the connecting rod 31 can move within the opening. Among them, there is a protrusion at the middle end of the inner bottom of the buffer cavity 331. The protrusion is integrated with the middle end of the inner bottom of the buffer cavity 331. The outer end of the protrusion is fixedly connected to the inner end of the coil spring 333. The outer side of the coil spring 333 can contact the inner side of the groove 312. When the bottom plate 311 is subjected to force, the groove 312 squeezes the outer side of the coil spring 333, causing the coil spring 333 to squeeze inward and then release the elastic force to reset. The elastic force can respond to pressure from different directions. Specifically, when encountering strong winds, the wind blows the bottom box 41, and the bottom box 41 can drive the buffer box 33 to move. During the movement, the arc plate 332 can squeeze the bottom plate 311, so that the bottom box 41 and the buffer box 33 can move to avoid facing the wind directly and unloading the force. At the same time, the inner side of the groove 312 can also squeeze the compression spring 333 to improve the movement effect and enhance the unloading effect.

[0027] Reference Figure 2 and Figure 5 The middle-end mechanism 34 includes a middle box 341, an active cavity 342, a through-hole 343, a spring 1 344 and an extrusion block 345. A group of middle boxes 341 are movably connected to the middle end of the outer side of the main rod 31. The inner end of the middle box 341 is provided with an active cavity 342. The upper and lower ends of the inner side of the active cavity 342 are provided with through-holes 343 corresponding to the connection to the main rod 31. The main rod 31 can be connected through the two groups of through-holes 343. No less than two groups of springs 1 344 are installed at equal intervals inside the active cavity 342. The other end of the spring 1 344 is fixedly connected to a group of extrusion blocks 345. The side of the extrusion blocks 345 close to the connection to the main rod 31 is all set to an arc shape, and the end of the extrusion blocks 345 close to the connection to the main rod 31 can be extended into the through-hole 343 and fit into the outer side of the connection to the main rod 31. Among them, a set of discs are fixedly connected to the upper and lower ends of the main rod 31 near the upper and lower ends of the middle box 341. The discs can cover the opening 343 to prevent impurities from falling into the opening 343 and affecting the normal use of the opening 343; Specifically, when the buffer box 33 is moved by the wind, the middle box 341 can be driven to move by connecting the auxiliary rod 35, and the outer side of the main rod 31 is squeezed by the spring 1 344 and the squeezing block 345 to achieve the moving effect, which can avoid the buffer box 33 and the bottom box 41 from directly resisting the strong wind and reduce the impact of the wind on the buffer box 33 and the bottom box 41.

[0028] Reference Figure 1 、 Figure 2 and Figure 6 The fixing mechanism 4 includes a bottom box 41, an inlet and outlet 42 and a roller 43. The bottom box 41 can store and protect the cables. The top of the bottom box 41 is fixedly connected to the bottom of the buffer box 33. Two sets of inlets and outlets 42 are opened on the left and right ends of the bottom box 41. The front and rear ends of the inlet and outlet 42 are rotatably connected to a set of rollers 43. The rollers 43 can protect the cables and reduce friction damage between the cables and the inlet and outlet 42 when the cables are in the inlet and outlet 42. A set of middle plates 411 are installed at the middle end of the bottom box 41. A set of through holes 412 are opened in the middle end of the middle plates 411, and a set of rotating wheels are rotatably connected at the positions of the left and right ends of the middle plates 411 near the front and rear ends of the through holes 412. The cables can contact the outside of the rotating wheels, which is conducive to bending the cables. At least two sets of sliding grooves 413 are opened at equal intervals on the left and right ends of the bottom surface of the bottom box 41. A set of clamping mechanisms 415 are connected to the sliding grooves 413 through springs 414. The bottom box 41 is designed as a spindle shape, which can effectively reduce wind resistance and reduce the impact of wind; The connection directions of the springs 2 414 in the two adjacent sets of the sliding grooves 1 413 are opposite, so that the positions of the two adjacent sets of the clamping mechanisms 415 are staggered, which is beneficial for the bending and storage of the cable.

[0029] Specifically, the cable enters the bottom box 41 through the inlet and outlet 42 at one end and the roller 1 43 inside the inlet and outlet 42, and extends out of the bottom box 41 from the inlet and outlet 42 at the other end and the roller 1 43 inside the inlet and outlet 42 after passing through the clamping mechanism 415 and the through hole 412 in sequence. The spring 2 414 can push the clamping mechanism 415 to move in a staggered manner, so that the cable is distributed in an "S" shape in the bottom box 41, thereby increasing the retained length of the cable in the bottom box 41. When the cable is stretched by strong wind, the clamping mechanism 415 can squeeze the spring 2 414 so that the cable is straightened in the bottom box 41, so that the extended cable can adapt to the length of the wind, thereby avoiding pulling the cable when the strong wind blows, thereby causing damage to the cable. After the wind dies down, the spring 2 414 pushes the clamping mechanism 415 and the cable to reset.

[0030] Reference Figure 6The clamping mechanism 415 includes a slider 1 4151, a clamping member 4152, a roller 2 4153, a slider 2 4154 and a spring 3 4156. The slider 1 4151 is slidably connected to the slide groove 1 413. The side of the slider 1 4151 close to the spring 2 414 is fixedly connected to the spring 2 414 and can be pushed along the slide groove 1 413 by the elastic force of the spring 2 414. A group of mouth-shaped clamping members 4152 are fixedly connected to the top of the slider 1 4151, which is convenient for the passage of the cable. A group of rollers 2 4153 are provided at the front and rear ends of the clamping member 4152. The upper and lower ends of the two groups of rollers 2 4153 are rotatably connected to a group of sliders 2 415 4. The upper and lower ends of the clamping member 4152 are both provided with second slide grooves 4155 corresponding to the two sets of second rollers 4153. The two sets of second rollers 4153 can move left and right in the clamping member 4152 through the cooperation between the second slider 4154 and the second slide groove 4155. The two sides of the two sets of second slide grooves 4155 at the bottom end that are away from each other are connected to the second slider 4154 through a third spring 4156. The two ends of the third spring 4156 are respectively fixedly connected to the inner side of the second slide groove 4155 at the bottom end and the outer side of the second slider 4154. The third spring 4156 can push the second roller 4153 through elastic force, so that the two sets of second rollers 4153 move relative to each other, thereby clamping the cable. Among them, the second roller 4153 and the first roller 43 are both concave wheels, which can improve the clamping effect of the cable and adapt to cables of different sizes, thereby increasing the scope of application.

[0031] Specifically, the cable is clamped by two sets of rollers 2 4153 , and the cable is bent or straightened as the slider 1 4151 moves.
