Description

Technical Field

[0001] The present application relates to the field of cable detection equipment technology, and in particular to a high-voltage cable safety puncture device. Background Art

[0002] In the power industry, the inspection and maintenance of high-voltage cables is of vital importance, as it is directly related to the stability and safety of the power system. Currently, the direct puncture method is commonly used to detect high-voltage cable faults. This involves using specialized puncture tools to secure the cable and then physically puncture it to determine the insulation condition inside the cable.

[0003] Most existing piercing tools are relatively random in fixing high-voltage cables, making it difficult to stably fix high-voltage cables. In addition, the piercing body is heavy. After being fixed to fixed furniture, the fixing clamp is not fixed to the ground, causing the piercing body to easily fall over. Ultimately, it is impossible to accurately pierce the predetermined position. Therefore, there is a lot of room for improvement.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

The bottom of one of the clamping plates 3 is fixedly connected to a suction cup 501 through two fixing columns 5. The two suction cups 501 can be used to fix the clamping plate 3 to the ground to prevent the main body 1 from tipping over due to its own gravity during the piercing process, which may cause inaccurate piercing of the high-voltage cable body 2. Both ends of the clamping plate 3 are fixedly connected to a supporting plate 502. The bottom of the supporting plate 502 is fixedly connected to two fixed feet 503. When the two suction cups 501 are fixed to the ground, the two fixed feet 503 contact the ground. The two supporting plates 502 support the high-voltage cable body 2 on both sides of the clamping plate 3, preventing the high-voltage cable body 2 from rotating, so that the left and right sides of the pierced area remain level, making the piercing more accurate.

[0021] Reference Figure 2 The two threaded rods 301 rotate through the two ends of the clamping plate 3 and are fixedly connected to the top of the other clamping plate 3. The threaded rods 301 are threadedly connected with threaded sleeves 302. The two threaded sleeves 302 can be rotated upward to pull up the clamping plate 3, and the high-voltage cable body 2 can be placed between the two clamping plates 3. Then, the two threaded sleeves 302 are rotated downward to drive one clamping plate 3 to be pressed down, thereby fixing the upper and lower sides of the high-voltage cable body 2.

[0022] Reference Figure 2 and Figure 3 One end of the two telescopic rods 4 is slidably connected to the two sliding holes 401 of the splint 3, and the other ends of the two telescopic rods 4 are slidably connected to the two sliding holes 401 of the other two splints 3.
