A cable fault location device for a distribution network according to claim 6, characterized in that: The inner surface of the outer gear ring (520) is sleeved with a rotating drum (530), wherein a driving motor (540) is provided at the end of the rotating drum (530), and the output end of the driving motor (540) is fixedly connected to the side opposite to the rotating drum (530). In order to assemble the material storage box body (300) and the driving motor (540) and provide power, the outer surface of the material storage box body (300) is sleeved with a base (200), and the end of the base (200) is fixedly connected to a mounting platform (210) via a support rod, and the front and rear ends of the bottom of the base (200) are equipped with battery packs (220) via a battery box.

8. A cable fault location device for a distribution network according to claim 7, characterized in that: A scraper bracket (600) is sleeved on the surface end of the rotating drum (530), wherein one side of the scraper bracket (600) is connected to a transmission shaft (610), and a plurality of anti-limit groove cavities (301) used in conjunction with the transmission shaft (610) are formed at the end of the material storage box body (300), and the transmission shaft (610) passes through the anti-limit groove cavities (301) and extends to the inner cavity of the material storage box body (300) and is connected to a scraper plate (620).

9. A cable fault location device for a distribution network according to claim 8, characterized in that: The bottom of the base (200) is connected to a bearing base (700) via a fixing rod, the right side of the end of the bearing base (700) is fastened with a splicing seat (710) via bolts, and the end of the splicing seat (710) is threadedly sleeved with a push rod (720), the right side of the bottom of the bearing base (700) is installed with a driving roller (740), one side of the end of the bearing base (700) is screwedly installed with a second driving motor (730), and the output end of the second driving motor (730) and the power shaft of the driving roller (740) are both sleeved with a bevel gear transmission member (750), and the two bevel gear transmission members (750) are meshed with each other.

10. A method for locating a cable fault in a distribution network, comprising the cable fault locating device in a distribution network according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. When locating a cable fault, the detection unit (110) is stored in the storage box (100), the storage box (100) is pushed in cooperation with the telescopic push-pull rod (103), and the storage box (100) is carried and moved in cooperation with the telescopic push-pull rod (103); the faulty cable is located and detected by the detection probe (120) in cooperation with the detection unit (110); S2. The user holds the push rod (720) and, with the second drive motor (730) as the power source, transmits power to the drive roller (740) through the bevel gear transmission member (750), driving the bearing base (700) and the detection probe (120) to move, and detects the cables laid around; S3. When the detection probe (120) detects that the cable at the corresponding position is abnormal, the drive motor 1 (540) is driven to drive the rotating drum (530), and the outer gear ring (520) and the inner gear ring (510) are used to drive the material-dispensing turntable (500), so that the material-dispensing turntable (500) retracts the discharge partition (400); S4. The discharge partition (400) is retracted inwardly to expose the end opening of the discharge barrel (310), so that the marked powder in the storage box (300) is put into the discharge barrel (310) and falls through the discharge hole (311), thereby physically marking the cable fault point at that location, so as to facilitate the subsequent secondary detection and positioning of the faulty cable; S5. When the driving motor 1 (540) drives the rotating drum (530), the rotating drum (530) synchronously drives the scraper bracket (600) to rotate, and then drives the scraper plate (620) to rotate a certain angle through the transmission shaft (610), and uses the scraper plate (620) to scrape the marking powder on the guide inclined plate (320) so that it cannot adhere to the inner wall of the guide inclined plate (320), thereby effectively marking and locating the cable at the abnormal location.
