[0023] The utility model provides a kind of electric power cable insulation fault positioning device, including one half circle storehouse 1 and two half circle storehouse 2, the inside fixed mounting of one half circle storehouse 1 and two half circle storehouse 2 has photoelectric diameter gauge 3, and one half circle storehouse 1 side slidingly connects with detection point position adjusting assembly 4, and detection point position adjusting assembly 4 includes slide 41, mounting plate 42, drive assembly 43 and driving wheel 44, and mounting plate 42 is fixedly connected in the side of slide 41, and drive assembly 43 is fixedly installed in the other end of mounting plate 42, and the output of drive assembly 43 is drivingly connected with the center of driving wheel 44, and drive assembly 43 includes driving motor 431 and speed changer 432, and the output of driving motor 431 is drivingly connected with the input of speed changer 432, and the output of speed changer 432 is drivingly connected with the center of driving wheel 44, and the both ends of one half circle storehouse 1 are respectively fixedly connected with one connecting plate 11, and the side of two one connecting plate 11 is fixedly connected with positioning rod 12 in symmetry, and the both ends of two half circle storehouse 2 are respectively fixedly connected with two connecting plate 21, and the side of two two connecting plate 21 is symmetrically provided with positioning hole 22, and the one end of positioning rod 12 is movably penetrated in the inside of positioning hole 22, and the one end of positioning rod 12 is threadedly connected with locating nut 13.

[0024] Embodiment two: as Figure 1 Figure 4 ​As shown, the power cable insulation fault location device of this utility model includes a first semi-circular chamber 1 and a second semi-circular chamber 2. A photoelectric diameter gauge 3 is fixedly installed inside the first semi-circular chamber 1 and the second semi-circular chamber 2. A detection point adjustment component 4 is slidably connected to one side of the first semi-circular chamber 1. The detection point adjustment component 4 includes a slide table 41, a mounting plate 42, a drive component 43 and a drive wheel 44. The mounting plate 42 is fixedly connected to one side of the slide table 41, and the drive component 43 is fixedly installed at the other end of the mounting plate 42. The output end of the drive component 43 is connected to the center of the drive wheel 44. An arc-shaped slide rail 14 is fixedly connected to one side of the first semi-circular chamber 1. The slide table 41 is slidably connected to the outside of the arc-shaped slide rail 14. Several positioning adjustment holes 141 are opened inside the arc-shaped slide rail 14. A positioning adjustment rod 411 is movably passed through the inside of the slide table 41. One end of the positioning adjustment rod 411 movably passes through the inside of a positioning adjustment hole 141 and is threadedly connected to another positioning nut 13.

[0025] The overall effect of this embodiment is that when the power cable insulation fault location device fails to determine the fault location after one inspection on the suspended cable, the positioning nut 13 is rotated, the positioning adjustment rod 411 is pulled out from the positioning adjustment hole 141, the position of the slide table 41 on the arc-shaped slide rail 14 is adjusted, and then the positioning adjustment rod 411 and the positioning nut 13 are installed respectively. Due to the adjustment of the position of the detection point adjustment component 4, the first semi-circular chamber 1 and the second semi-circular chamber 2 are rotated around the cable as the axis under the action of gravity, and the detection area of ​​the photoelectric diameter gauge 3 is replanned and adjusted to cover the area missed in the first inspection process. After two inspection operations, it is ensured that the photoelectric diameter gauge 3 can achieve all-round, no-dead-angle inspection of the outer surface of the suspended cable, thereby effectively improving the integrity and accuracy of cable inspection.

[0026] The usage and working principle of this device are as follows: First, place the No. 2 semi-circular chamber 2 on the suspended cable to be tested. Then, pass the positioning rods 12 at both ends of the No. 1 semi-circular chamber 1 through the positioning holes 22. Rotate the positioning nut 13 to install the No. 1 semi-circular chamber 1 and the No. 2 semi-circular chamber 2 on the suspended cable to be tested. The two photoelectric diameter gauges 3 respectively test the surface of the cable. At the same time, the drive motor 431 drives the speed reducer 432 to work. The speed reducer 432 drives the drive wheel 44 to rotate, driving the power cable insulation fault location device to adjust the detection point on the suspended cable. When the light from the photoelectric diameter gauge 3 shines on the surface of the cable, it will be reflected or blocked. The photoelectric sensor in the diameter gauge receives these light signals and converts them into electrical signals, thereby measuring the diameter data of the cable. When the diameter data of the cable is less than the standard data, it is determined that there is damage to the outer surface of the cable in this area. The drive motor 431 stops working, thereby locating the fault in the insulation layer of the power cable.

[0027] If the power cable insulation fault location device fails to pinpoint the fault location after one inspection of the suspended cable, the positioning nut 13 is rotated to pull the positioning adjustment rod 411 out of the positioning adjustment hole 141. The position of the slide table 41 on the arc-shaped slide rail 14 is adjusted, and then the positioning adjustment rod 411 and the positioning nut 13 are installed again. Due to the adjustment of the position of the detection point adjustment component 4, the first semi-circular chamber 1 and the second semi-circular chamber 2 rotate around the cable as the axis under the action of gravity. This re-plans and adjusts the detection area of ​​the photoelectric diameter gauge 3, aiming to cover the area missed in the initial inspection process. After two inspection operations, it is ensured that the photoelectric diameter gauge 3 can achieve all-round, blind-angle inspection of the outer surface of the suspended cable.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
