Figure 7 This is a perspective view of the protection section in a cable terminal tower cable protection device according to this application. Figure 8 This is a perspective view of the protected section in a cable terminal tower cable protection device according to this application.Figure 6 , Figure 7 and Figure 8 As shown, the protection mechanism 33 includes at least one set of protection components 331. Each set of protection components 331 includes at least twenty protection segments 332. Adjacent protection segments 332 are sequentially hinged end-to-end. Each protection segment 332 includes a set of third rotating plates 3321 and a support block 3322 connected between the third rotating plates 3321. The support block 3322 also has a cable 20 limiting hole in the middle. Each set of third rotating plates 3321 includes two third rotating plates 3321. Specifically, a support block 3322 is provided between the two third rotating plates 3321, and the support block 3322 is used to support the two... The third rotating plate 3321 has a hinge hole 313A at one end and an arc-shaped limiting groove 3231 at the other end. A hinge post 3232 is located at the center of the bottom of the arc-shaped limiting groove 3231. A right-angle limiting groove 3132 is also provided at the end of the third rotating plate 3321 near the arc-shaped limiting groove 3231. A baffle 314 is sandwiched between each third rotating plate 3321 and the support block 3322. Both ends of the third rotating plate 3321 are arc-shaped joints 3131. It should be noted that the baffle 314 on one protective section 332 and... The right-angled limiting groove 3132 on another protection segment 332 or the right-angled limiting groove 3132 on the second rotating plate 323 can cooperate with each other. Simultaneously, the right-angled limiting groove 3132 in one protection segment 332 can also cooperate with the baffle 314 on the first rotating plate 313. Furthermore, the hinge hole 313A on one protection segment 332 cooperates with the hinge post 3232 on another protection segment 332 or the hinge post 3232 provided in the arc-shaped limiting groove 3231 on the second rotating plate 323. The hinge post 3232 on one protection segment 332 can also cooperate with the first rotating plate 313. The hinge hole 313A on 13 is matched with the arc-shaped limiting groove 3231 of the third rotating plate 3321 of one protection section 332 and the arc-shaped connector 3131 of the third rotating plate 3321 on another protection section 332 relative to the arc-shaped limiting groove 3231 or the arc-shaped connector 3131 on the first rotating plate 313. The arc-shaped connector 3131 of the third rotating plate 3321 of one protection section 332 relative to the arc-shaped limiting groove 3231 can also match the arc-shaped limiting groove 3231 on the second rotating plate 323. The limiting holes 312A of each cable are connected.

[0042] Here, when the arc-shaped limiting groove 3231 cooperates with the corresponding arc-shaped connector, the protection section 332 swings along a preset direction during the daily protection of the cable 20. The range of rotation of the arc-shaped connector around the hinge point with the arc-shaped limiting groove 3231 is limited to prevent excessive swinging of the protection mechanism 33, which could cause excessive bending of the cable 20 and damage to the cable 20, thereby protecting the integrity of the cable 20. In addition, the cooperation between the right-angle limiting groove 3132 and the baffle 314 is to prevent the cable 20 from tilting excessively towards the tower 10 during the daily installation of the cable 20, which could result in insufficient safety distance. Specifically, according to actual needs, the protection mechanism 33 cannot be bent on the side where the right-angle limiting groove 3132 cooperates with the baffle 314, and remains flat.

[0043] Here, the cable 20 is connected to the tower body 10, and the limiting protection device 30 covers the cable 20. The limiting protection device 30 includes a first end protection head 31, a second end protection head 32, and a protection mechanism 33 hinged between the first end protection head 31 and the second end protection head 32. The first end protection head 31 includes a first connecting seat 311, a first limiting head 312 connected to the first connecting seat 311, and a set of first rotating plates 313 connected to the first limiting head 312. The first limiting head 312 has a cable 20 limiting hole in the middle. The second end protection head 32 includes a second connecting seat 321, a connecting... The second limiting head 322 is connected to the second connecting seat 321, and a set of second rotating plates 323 are connected to the second limiting head 322. The second limiting head 322 is also provided with a cable 20 limiting hole in the middle. The protection section 332 includes a set of third rotating plates 3321 and a support block 3322 connected between the third rotating plates 3321. The support block 3322 is also provided with a cable 20 limiting hole in the middle. The cable 20 limiting holes are connected to each other, which improves the stability of the cable 20 and avoids the risk of the cables 20 getting tangled together during the daily operation of the cable terminal tower cable protection device.

[0044] To facilitate understanding, the working principle of this application is further described as follows: In use, the cable 20 passes through the cable limiting hole 312A of each structure, so that the protection mechanism 33 completely covers the cable 20, and is connected to the fixed ends of the cable 20 at both ends of the cable 20 by bolts through the first connecting seat 311 on the first end protection head 31 and the second connecting seat 321 on the second end protection head 32.

[0045] For cables 20 that require special protection, such as those that are biased towards the tower body 10 and pose a risk to their safe distance, the cables 20 can be wrapped by the cooperation between the right-angled limiting groove 3132 and the baffle 314 (the side where the right-angled limiting groove 3132 and the baffle 314 cooperate is the vertical side and cannot be bent). According to actual needs, the staff can choose to place the side of the cable 20 that cannot be bent inward closer to the side where the right-angled limiting groove and the baffle 314 are combined, and the side that can be bent inward closer to the opposite side, which effectively improves the stability of the use of the cables 20 and avoids the risk of the cables 20 getting tangled together.
