[0044] See also Figure 3 , Fig.11 and Fig.12 In one embodiment of the present invention, the support shell 1 includes a first fixed tube 11, a support frame 12, a second fixed tube 13, an adapter 15, an insulating tube 16, a first galvanized rod 17 and a second galvanized rod 18, the support frame 12 is fixedly connected between the first fixed tube 11 and the second fixed tube 13, the drive module 53 is fixedly connected to the support frame 12, the threaded adjustment tube 51 is rotatably connected between the first fixed tube 11 and the second fixed tube 13, the copper tube sleeve 14 is fixedly connected in the second fixed tube 13, the adapter 15 is fixedly connected to the end of the second fixed tube 13, the insulating tube 16 is fixedly connected to the adapter 15, the base 4 is rotatably connected to the insulating tube 16, one end of the first galvanized rod 17 is fixedly connected to the copper tube sleeve 14, the first galvanized rod 17 passes through the insulating tube 16, one end of the second galvanized rod 18 is rotatably connected to the other end of the first galvanized rod 17, and the other end of the second galvanized rod 18 is fixedly connected to the lightning rod 8.

[0045] See also Figure 3 and Fig.11 Furthermore, a copper pressing block 551 and a copper ball head 552 are respectively provided at both ends of the copper rod 55, the copper pressing block 551 is in contact with the surface of the bridge cable 3, a conductive groove 141 is provided on the inner wall of the copper tube sleeve 14, and the copper ball head 552 is in sliding contact with the conductive groove 141.

[0046] In the embodiment of the present invention, the first galvanized rod 17 is an L-shaped rod, the rotation axis of the first galvanized rod 17 is consistent with the axis of the insulating tube 16, and the copper pressing block 55 has the functions of conducting electricity and pressing the bridge cable 3 at the same time.

[0047] Working principle: When installing the bridge cable 3, first pass one end of the bridge cable 3 through the cable hole 215, and wrap the bridge cable 3 in the cable groove 211, and then use the locking nut 571 and the anchor bolt 57 to connect the first anchor plate 214 and the second anchor plate 56. At this time, the copper pressure block 551 abuts against the surface of the bridge cable 3 to pre-fix the bridge cable 3. Then use the driving module 53 and the transmission gear to control the rotation of the threaded adjustment tube 51. Due to the sliding contact between the guide key 111 and the guide groove 212, the rotating threaded adjustment tube 51 controls the connection frame 21 to move toward the first fixed tube 11 through the threaded rod 52. The pressure block 222 that moves with the connection frame 21 slides with the first fixed tube 11 using the inclined surface of the surface The connection method drives the pressure block 222, the arc plate 221 and the clamp 223 to move radially along the guide rail 216. The two clamps 223 are used to clamp the bridge cable 3 in the cable groove 211. The flexible seals 225 on both sides are tightly wrapped around the surface of the bridge cable 3 to seal the cable hole 215. When it is necessary to adjust the traction angle of the support shell 1 or the bridge cable 3 with the insulating tube 16 as the axis, since the first galvanized rod 17 rotates coaxially with the insulating tube 16, and the first galvanized rod 17 is rotatably connected with the second galvanized rod 18, it is no longer necessary to re-disassemble the second galvanized rod 18 according to the change of the traction angle of the support shell 1, and the displacement sensor 7 and the pressure sensor 6 are used to monitor the coordinate parameters of the end of the bridge cable 3 and the traction force of the bridge cable 3 respectively;

[0048] When the bridge cable 3 is struck by lightning, the current is introduced into the ground along the bridge cable 3, the copper pressing block 551, the copper rod 55, the copper ball head 552, the conductive groove 141, the copper tube sleeve 14, the first galvanized rod 17, the second galvanized rod 18 and the lightning rod 8. Similarly, the lightning rod 8 can also shunt the current to each bridge cable 3 through the second galvanized rod 18, the first galvanized rod 17, the copper tube sleeve 14, the copper pressing block 551, the copper rod 55, the copper ball head 552 and the conductive groove 141.

[0049] When extreme weather causes changes in stress or traction on the surface of the cable 3, since the pressure sensor 6 can monitor the traction parameters of the cable 3 in real time, when extreme weather causes changes in stress or traction parameters on the surface of the cable 3, the remote computer controls the driving module 53 to adjust the position of the connecting frame 21 in the first fixed tube 11 or adjusts the coordinate parameters of the end of the cable 3 according to the traction abnormality data transmitted by the pressure sensor 6, thereby ensuring that the cable 3 is within the standard traction threshold, thereby extending the service life of the cable 3.

[0050] In summary, the present application utilizes the design of mutual cooperation among the supporting shell 1, the anchoring device 2, the adjusting device 5, the pressure sensor 6 and the displacement sensor 7. (1) On the one hand, the anchor bolt 57 is used to connect the first anchoring plate 214 and the second anchoring plate 56, and at the same time, the copper pressure block 551 is driven to pre-fix the bridge cable 3, thereby preventing the bridge cable 3 from falling off from the cable groove 211 during the process of the connecting skeleton 21 entering the first fixed tube 11. On the other hand, during the process of the connecting skeleton 21 entering the first fixed tube 11, the pressure block 222 can be used to slide with the first fixed tube 11 to drive the clamp 223 to clamp and fix the bridge cable 3 in the cable groove 211. The flexible sealing member 225 is tightly wrapped around the surface of the bridge cable 3. When the pressure block 222 is separated from the first fixed tube 11, the elastic force of the return spring 224 drives the clamp 223 to separate from the bridge cable 3. The bridge cable 3 is easy to disassemble and assemble and has good sealing performance.

[0051] (2) When the bridge cable 3 is struck by lightning, the current is introduced into the ground along the bridge cable 3, the copper pressure block 551, the copper rod 55, the copper ball head 552, the conductive groove 141, the copper tube sleeve 14, the first galvanized rod 17, the second galvanized rod 18 and the lightning rod 8. Since the first galvanized rod 17 rotates coaxially with the insulating tube 16 and the first galvanized rod 17 and the second galvanized rod 18 are rotatably connected, the structural design not only has the function of absorbing lightning and draining the current into the ground, but also can keep the installation position of the second galvanized rod 18 unchanged when adjusting the traction of the bridge cable 3, and has the characteristics of lightning absorption and easy adjustment.

[0052] Since the displacement sensor 7 and the pressure sensor 6 are used to monitor the coordinate parameters of the end of the bridge cable 3 and the traction of the bridge cable 3 respectively, when extreme weather causes changes in the stress or traction on the surface of the bridge cable 3, the remote computer controls the driving module 53 to adjust the position of the connecting skeleton 21 in the first fixed tube 11 or adjust the coordinate parameters of the end of the bridge cable 3 according to the abnormal traction data transmitted by the pressure sensor 6, thereby ensuring that the bridge cable 3 is within the standard traction threshold, thereby extending the service life of the bridge cable 3 and having the characteristics of automatically adjusting the traction of the bridge cable 3 or the coordinate parameters of the end of the bridge cable 3.
