The contact switch 23 is aligned with the front end of the rectangular hole of the limit plate 20, and the contact switch 23 is electrically connected to the controller of the motor 12.

[0030] The spring 10 elastically connects the shaft rod 9 and the anchor rod 2, and the shaft rod 9 is rotationally connected to the middle and rear part of the wire clamp shell 1 through the pull rod 11, thereby shock-absorbing and buffering the swing and extension of the wire clamp shell 1, reducing the impact on the cable and increasing the service life of the cable. Example 3

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, on the basis of embodiments 1 and 2, it also includes a motor 12, a drive shaft 13 and a pendulum 14, the motor 12 is installed on the wire clamp housing 1, the output shaft of the motor 12 is transmission-connected with the drive shaft 13, the drive shaft 13 is rotatably installed on the wire clamp housing 1, one end of the pendulum 14 is connected to the drive shaft 13, and a striking hammer is arranged at the other end of the pendulum 14; it also includes a torsion spring 19, one end of the pendulum 14 is rotatably mounted on the drive shaft 13, one end of the torsion spring 19 is connected to the drive shaft 13, and the other end of the torsion spring 19 is connected to the pendulum 14.

Since the cable power supply device and the power supply module belong to the prior art, the circuit setting of the cable power supply device is not described in detail here; the controller of the motor 12 integrates a KSD301 low-temperature thermostat and a B30 tilt switch. The temperature control switch allows the motor to be turned on only at freezing temperatures, and the tilt switch prevents the motor from being turned on when excessive tilting and swinging occurs, to avoid accidental contact with the switch due to changes in cable tension caused by wind, hovering birds, etc., which causes the motor to be turned on accidentally. Since the temperature control switch and the tilt switch belong to the prior art, the temperature control switch and the tilt switch are not described here. The circuit setting of the switch is not described in detail. When the cable is frozen, the tension of the cable on the two clamping plates 3 and the clamp shell 1 increases. The clamp shell 1 pulls the shaft 9 forward through the pull rod 2 11, so that the shaft 9 and the anchor rod 2 are relatively far away from each other to compress the spring 10, so that the rear end of the rectangular hole of the limit plate 20 is close to the contact switch 1 22. When the contact switch 1 22 is triggered, the device determines that the cable is too thickly frozen.

The pendulum 14 is elastically connected to the drive shaft 13 through the torsion spring 19, and the drive shaft 13 drives the pendulum 14 to swing through the torsion spring 19. When the striking hammer strikes the cable, the torsion spring 19 buffers the pendulum 14 to avoid damage to the motor 12, so that the cable vibrates, shakes off the ice, and improves the safety of the cable.

[0034] When the cable between the poles breaks and the broken ends of the cable fall to the ground, the ground will become a high-voltage danger zone. At this time, the tension of the cable on the two clamping plates 3 and the clamp housing 1 is reduced, so that the spring 10 is extended, and the shaft rod 9 is relatively close to the anchor rod 2. The elastic force of the spring 10 pulls the shaft rod 9 toward the anchor rod 2, so that the front end of the rectangular hole of the limit plate 20 is close to the contact switch 23.

The motor 12 drives the drive shaft 13 to rotate reciprocatingly, and the drive shaft 13 drives the swing arm 17 to reciprocate. The swing arm 1 17 continuously pushes the swing arm 2 18 to swing back and forth, so that the swing arm 2 18 reciprocates and drives the driving shaft of the hydraulic unit 15, thereby pressurizing the hydraulic oil in the hydraulic unit 15, so that the hydraulic oil drives the cutter 16 to extend, and the cutter 16 cuts the cable from the front end surface of the wire clamp shell 1. When the cutter 16 cuts the cable, the insulating plate 24 insulates and blocks the cross section of the cable to reduce leakage of the cable cross section. The two broken sections of the cable between the two poles fall to the ground after being cut, thereby avoiding the broken ends of the charged cable falling on the ground to form a dangerous area, thereby improving the safety under the cable.

Then, when the cable is frozen, the clamping shell 1 pulls the shaft 9 forward through the pull rod 11, so that the limit The rear end of the rectangular hole of the limit plate 20 is close to the contact switch 22. When the contact switch 22 is triggered, the device determines that the cable is too thickly frozen. The contact switch 22 sends a signal to the controller of the motor 12. The motor 12 starts to drive the drive shaft 13 to rotate reciprocatingly.

Finally, when the cable breaks, the elastic force of the spring 10 pulls the shaft rod 9 toward the anchor rod 2, so that the front end of the rectangular hole of the limit plate 20 is close to the contact switch 23. When the contact switch When switch 23 is triggered, the device determines that the cable is broken, and contact switch 23 sends a signal to the controller of motor 12. Motor 12 drives drive shaft 13 to rotate back and forth, and drive shaft 13 drives swing arm 17 to swing back and forth, so that swing arm 17 continuously pushes swing arm 2 18 to swing back and forth, thereby swing arm 2 18 reciprocates and drives the drive shaft of hydraulic unit 15, thereby pressurizing the hydraulic oil in hydraulic unit 15, so that hydraulic oil drives cutter 16 to extend, so that cutter 16 cuts the cable, and insulating plate 24 insulates and blocks the cross section of the cable to reduce leakage of the cable cross section.
