The proportion of cables in power lines is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of power systems. During cable production, a certain number of samples are taken to test the insulation resistance to determine if the cable's insulation resistance meets the requirements. During testing, the cable sample is placed in a water tank, and then both ends are connected to an insulation resistance tester to measure the cable's insulation resistance.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0020] Reference Figures 1 to 4 This utility model discloses a cable insulation resistance testing device, which includes a water tank 1, a cover 3 fitted around the top of the water tank 1, a movable door 4 installed on the front side of the cover 3, support plates 2 connected to the left and right outer walls of the water tank 1 respectively, and the bottom of the cover 3 is open. Wire holes 6 are provided on both the left and right sides of the cover 3, and a horizontal plate 14 is bolted to the right outer wall of the cover 3 near the bottom. An L-shaped plate 13 is bolted to the top of the horizontal plate 14, and a rotating plate 10 is movably connected to the front inner wall of the L-shaped plate 13 via a rotating shaft and bearing. A reduction motor 15 is bolted to the rear wall of the L-shaped plate 13, and the rear end of the rotating shaft on the rear wall of the rotating plate 10 passes through the inner ring of the bearing and is connected to the output shaft of the reduction motor 15. Arc plates 7 are bolted to the front wall of the rotating plate 10 near the top and bottom respectively, and a winding roller 12 is provided between the two arc plates 7, with a wire inlet hole 11 on the winding roller 12.
[0021] Two curved plates 7 are connected to snap-fit blocks 9 on opposite sides near the left and right sides. The top and bottom of the take-up roller 12, near the rear side, are respectively provided with snap-fit grooves 8 that match the snap-fit blocks 9. This structure enables effective and uniform winding, thereby enabling effective and uniform detection and improving its detection efficiency.
[0022] A mounting plate 16 is installed near the bottom inside the cover 3, and several evenly distributed cable trays 17 are connected to the bottom of the mounting plate 16. An electric cylinder 5 is connected through the top of the cover 3, and the bottom end of the push rod on the electric cylinder 5 is bolted to the top of the mounting plate 16.

[0023] Working Principle: In this technical solution, the cable is first positioned as required by the support plate 2. Then, the right end of the cable is sequentially passed through the threading hole 6, threading hole 17, and inlet hole 11. Next, the push rod of the electric cylinder 5 moves downward, causing the mounting plate 16 and cable tie tube 17 to move downward, bringing the bottom of the cable into contact with the guide wheel 18. The reduction motor 15 drives the winding roller 12 to rotate slowly via the rotating plate 10, arc plate 7, snap-fit block 9, and snap-fit groove 8. The left end of the cable is then connected to the insulation resistance tester, while the right end is connected sequentially to the insulation resistance tester as the winding roller 12 winds up. This allows for effective and uniform winding, resulting in efficient and uniform testing, improving testing efficiency, accurately locating damaged areas, and enhancing overall efficiency.
