[0049] A cable high voltage detector comprises a shielding shell 21 for installing a cable and a cable detector 11. A transformer is installed in the cable detector 11 and the transformer is externally connected to a power supply. The shielding shell 21 is fixedly connected to the side wall of the cable detector 11. The cover plate 22 is rotatably connected to the shielding shell 21. A placement cavity 23 with an opening facing upward is provided in the shielding shell 21. A bottom plate 27 is fixedly connected to the bottom wall of the placement cavity 23. Two fixing rods 28 are provided and are symmetrically fixedly connected to the top wall of the bottom plate 27. A sliding groove is provided on the top wall of the bottom plate 27. A sliding rod 30 is slidably connected in the sliding groove. A plurality of limiting rings 29 are provided and the limiting rings 29 are fixedly connected to the fixing rods 28 in pairs in a symmetrical position. A guide block 33 is fixedly connected to the side wall of the placement cavity 23.

[0050] In order to clamp and fix the cable, a clamping assembly is also provided, which includes: a clamping plate 24 and a threaded rod 26. The clamping plate 24 is fixedly connected to the side wall of the placement cavity 23, and two symmetrical slots 25 are provided on the clamping plate 24. The threaded rod 26 is rotatably connected to the top wall of the clamping plate 24 and one end of the threaded rod 26 extends into the slot 25. The threaded rod 26 is made of plastic, and a conductive plate is provided in the slot 25, which is electrically connected to the transformer in the cable detector 11.

[0051] In order to drive the sliding rod 30 to reciprocate in the horizontal direction, a reciprocating assembly is also provided, which includes: a driving motor 31, a gear 32, a rack 20, a limiting plate 34, a connecting plate 35, and a guide shaft 19. The driving motor 31 is fixedly connected to the side wall of the shielding shell 21, the gear 32 is fixedly connected to the output shaft of the driving motor 31, the rack 20 is slidably connected to the side wall of the placement cavity 23, the rack 20 is provided with a waist-shaped hole, and a plurality of latch teeth are evenly spaced on the side walls around the waist-shaped hole, and the gear 32 is located in the waist-shaped hole of the rack 20 and meshes with the latch teeth. A square block is fixed at the lower end of the sliding rod 30, and two limiting plates 34 are provided and fixedly connected to the square block below the sliding rod 30 in a symmetrical position, and the two ends of the limiting plate 34 are in sliding contact with the two end side walls of the rack 20. The connecting plate 35 is fixedly connected to the top wall of the rack 20 , the guide shaft 19 is fixedly connected to the connecting plate 35 , and the guide shaft 19 is in sliding contact with the guide block 33 .

[0052] Working or installation process:

[0053] Open the cover plate 22, and insert one end of the cable into a slot 25, then rotate the threaded rod 26, which is threadedly connected with the clamping plate 24 so that the threaded rod 26 moves downward, and the threaded rod 26 moves downward and presses one end of the cable in the slot 25, and the cable is passed around one of the fixing rods 28 so that the cable is located between two limit rings 29 on the fixing rod 28; then pass the cable around the sliding rod 30 and pass the other end of the cable around another fixing rod 28, and finally insert the other end of the cable into another slot 25, and rotate another threaded rod 26; fix the two ends of the cable in the slot 25 by the two threaded rods 26, so that the cable presents a triangular shape;

[0054] Cover the cover plate 22 and energize the transformer in the cable detector 11. The shield shell 21 and the cover plate 22 are used to electrically shield the cable during high-voltage detection, so that the human body and electrical equipment are protected from interference and harm from the high-voltage power supply.

[0055] The driving motor 31 is started, and the output shaft of the driving motor 31 drives the gear 32 to rotate. The gear 32 engages with the latch teeth to drive the rack 20 to move. The rack 20 moves and pushes the limit plate 34. The limit plate 34 drives the sliding rod 30 to move horizontally back and forth in the slide groove. Since the guide shaft 19 is in sliding contact with the side wall of the guide block 33, the guide shaft 19 is guided by the side wall of the guide block 33, so that during the horizontal reciprocating movement of the rack 20, the rack 20 moves up and down along the arc surface of the waist-shaped hole in a certain period of time;

[0056] During the reciprocating movement of the sliding rod 30, the sliding rod 30 pulls the cable wound around the sliding rod 30 and changes the shape of the cable triangle. During the high-voltage detection of the cable, the reciprocating movement of the sliding rod 30 makes the cable statically curved, thereby increasing the authenticity of the cable detection.

[0057] After the inspection is completed, the staff turns off the transformer, opens the cover plate 22 , and rotates the threaded rod 26 in the opposite direction to take the cable inserted into the slot 25 out of the placement cavity 23 .

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
