Description

Technical Field

[0001] The present invention relates to the technical field of cable detection devices, and in particular to a cable fault detection device used in a distribution network. Background Art

[0002] Cable fault detector is an important tool for maintaining various cables as the smooth flow of wired communications and the transmission of electricity depend on the normal operation of cable lines. It adopts multiple fault detection methods and applies the most advanced electronic technology achievements of the contemporary era. Before detecting cable faults, the detector needs to be used with a detection rod to locate the cable fault site and further repair the cable.

[0003] However, when using a traditional cable fault detection device, when the fault site is found, a rod is inserted into the ground, and then a branch or a carried tool is used to mark the location. The marking traces are similar to the surrounding environment. It is easy to see the marks clearly when digging, and it is easy to dig up the cable by mistake, causing secondary damage. At the same time, when detecting the cable position on dry and hard ground, the positioning stability is poor due to the sharp end of the rod and the small ground contact area. In a dry environment, the detection head needs to be moistened with water, and the amount of water added will affect the use effect of the detection head, and then affect the detection efficiency. Since the detector needs to view the data presented on it at any time, the outer shell is easy to rotate and close when the operator walks, which affects the operator's observation and the use effect of the detector.

Continue to press, and the squeeze block 908 then slides, and the seventh spring 909 is then stretched, and the squeeze block 908 drives the wet sponge layer 907 to moisten the detection head. When the detection head needs to be used for detection, the pressing rod 901 is pressed, and the pressing rod 901 slides and then presses down the connecting column 902. The sixth spring 904 is compressed, and the connecting column 902 slides and drives the protective groove 906 on the protective block 905 to separate from the detection head. The second torsion spring 903 is reset, and then drives the connecting column 902 to rotate to the outside. At this time, the pressing rod 901 is released, and the connecting column 902 drives the protective block 905 to rise, exposing the detection head. When the sponge layer 907 inside the protective groove 906 is no longer wet, water can be added to the internal sponge layer 907 through the water injection hole 910;

[0050] When it is necessary to open the housing 2, the pressing bar 401 is pressed, and the pressing bar 401 slides and drives the card block 404 to slide out of the card slot of the limit block 403, thereby releasing the limit of the card block 404. At the same time, the pressing bar 401 slides and drives the connecting rod 407 to slide. The sliding of the connecting rod 407 causes the roller 409 to roll inside the guide groove 408. The rolling of the roller 409 drives the connecting bar 410 and the card column 411 to slide. The card column 411 then slides out of the card hole 412 on one side of the rotating shaft 302. At this time, the first torsion spring 303 is reset. Under the action, the rotating shaft 302 drives the shell 2 to rotate, and the shell 2 is opened. At the same time, due to the torsion of the first torsion spring 303, the shell 2 is effectively prevented from rotating during use. At this time, since the clamping column 411 is in conflict with the bottom end of the rotating shaft 302, the connecting rod 407 and the pressing bar 401 are not reset. When the shell 2 is closed, when the clamping column 411 slides into the inside of the clamping hole 412, under the action of the first spring 405, the pressing bar 401 is reset, and the clamping block 404 is also clamped into the clamping groove on one side of the limit block 403, thereby closing the shell 2.
