The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0027] like Figure 1-Figure 3 As shown, a fault detection device for a power distribution line of the utility model is shown, comprising a wirelessly connected walking component 1 and a control component 2, wherein the walking component 1 comprises a bottom support frame 11, a top support frame 12, a first roller 41 and a second roller 42. The bottom support frame 11 is U-shaped, the top support frame 12 is inverted U-shaped, and the bottom of the first side of the top support frame 12 is higher than the bottom of the second side of the top support frame 12. A placement gap 13 is provided between the top of the first side of the bottom support frame 11 and the bottom of the first side of the top support frame 12, so as to allow the wire 3 to be placed on the first roller 41 through the placement gap 13; the top of the second side of the bottom support frame 11 is fixedly connected to the bottom of the second side of the top support frame 12, and a fault detector is fixedly connected to the outer wall of the connection between the bottom support frame 11 and the top support frame 12. The first roller 41 is lower than the top upper plane of the bottom support frame 11, and both ends of the rotating shaft of the first roller 41 pass through the bottom support frame 11. One end of the first roller 41 is fixedly connected to a code disk 15, and an optocoupler counter 16 adapted thereto is provided on the outer side of the code disk 15. The second roller 42 is located above the first roller 41 . The first roller 41 and the second roller 42 are both provided with arc grooves adapted to the outer surface of the wire 3 to allow the wire 3 to pass through the two arc grooves between the first roller 41 and the second roller 42 .

[0028] In this embodiment, the wire 3 is first placed on the first roller 41 through the placement gap 13, so that the wire 3 passes through the two arc grooves between the first roller 41 and the second roller 42, and is fixed between the first roller 41 and the second roller 42. When the first roller 41 and the second roller 42 roll, they can move along the wire 3, so that the fault detector fixed at the connection between the bottom support frame 11 and the top support frame 12 can detect the fault of the wire 3. At the same time, when the first roller 41 rotates, the code disk 15 rotates accordingly, and the optical coupler counter 16 can collect the number of rotations of the first roller 41. After the fault detector detects the fault point, the data collected by the optical coupler counter 16 is transmitted to the control component 2 through wireless communication, thereby obtaining the accurate fault point.

[0029] Furthermore, the fault detector is a contactless fault detector 14, which uses a triode composite amplifier circuit, and the alternating current generates an alternating magnetic field to cause electromagnetic induction of the antenna, generating a weak signal, and the signal is most obvious when the induction coil is placed orthogonally to the wire 3. The contactless fault detector 14 can detect whether there is a fault point in the wire 3 without directly contacting the wire 3, making the detection process safer.

[0030] like Figure 1 and Figure 2 As shown, the walking assembly 1 also includes a movable frame 17 and a hand-tightening bolt 18. The movable frame 17 is adapted to the inner side of the top support frame 12, and the outer wall of the movable frame 17 is in contact with the inner wall of the top support frame 12 and can slide relative to each other. The second roller 42 is rotatably installed in the movable frame 17; a second threaded hole (not shown) is provided at the top of the top support frame 12 to allow the hand-tightening bolt 18 to be threadedly connected to the top support frame 12 through the second threaded hole, and a first threaded hole (not shown) is provided at the top of the movable frame 17 to allow the hand-tightening bolt 18 to be threadedly connected to the movable frame 17 through the first threaded hole.

[0031] Furthermore, both ends of the rotating shaft of the second roller 42 pass through the movable frame 17 . When the first roller 41 rotates, the electric wire 3 can drive the second roller 42 to rotate in the movable frame 17 .

[0032] When installing the walking assembly 1, first place the wire 3 on the first roller 41 through the placement gap 13, and then turn the hand-tightening bolt 18 to make the movable frame 17 slide downward along the inner wall of the top support frame 12, so that the second roller 42 descends, making the distance between the two arc grooves between the first roller 41 and the second roller 42 smaller, and squeezing the wire 3 between the first roller 41 and the second roller 42 to complete the installation of the walking assembly 1.

[0033] When removing the walking assembly 1, the hand-tightening bolt 18 is rotated in the opposite direction to make the movable frame 17 slide upward along the inner wall of the top support frame 12, so that the second roller 42 rises, and the distance between the two arc grooves between the first roller 41 and the second roller 42 becomes larger, and then the wire 3 is taken out through the placement gap 13, and the removal of the walking assembly 1 is completed.

[0034] In this embodiment, a movable frame 17 and a hand-tightened bolt 18 are used to move the second roller 42 in the vertical direction. By adjusting the distance between the two arc grooves between the first roller 41 and the second roller 42, the walking component 1 can be installed on the wire 3 and can be suitable for wires 3 of different sizes.

[0035] like Figure 1 As shown, the walking assembly 1 also includes a first gear 31, the first gear 31 is fixedly connected to the other end of the first roller 41, and the outer side of the first gear 31 is transmission-connected to the second gear 32. The first gear 31 can be driven to rotate by the rotation of the second gear 32, and since the first gear 31 is fixedly connected to the first roller 41, the first roller 41 can be further rotated, and at the same time, the code disk 15 fixedly connected to one end of the first roller 41 also rotates accordingly, and the optical coupler counter 16 counts the number of rotations of the first roller 41 through the code disk 15.

[0036] like Figure 2 As shown, the walking assembly 1 also includes a motor 19. The output end of the motor 19 passes through the bottom support frame 11 from the second side surface of the bottom support frame 11 and is fixedly connected to the second gear 32 for driving the second gear 32 to rotate, thereby driving the first gear 31 to rotate.

[0037] At this time, the second gear 32 is rotated by controlling the motor 19, so that the cooperation between the second gear 32 and the first gear 31 drives the first roller 41 to rotate, thereby driving the walking component 1 to move along the wire 3. The first gear 31 also drives the code disk 15 to rotate, and cooperates with the optical coupler counter 16 to count the number of rotations of the first roller 41, thereby recording the forward length. At the same time, the contactless fault detector 14 performs fault detection, and when a fault occurs, the length of the fault point collected by the optical coupler counter 16 is transmitted to the control component 2 through wireless communication.

[0038] like Figure 1 and Figure 2 As shown, the walking component 1 also includes a mobile power supply 4, which is arranged at the bottom of the bottom support frame 11, and the mobile power supply 4 is also respectively connected to the motor 19, the fault detector 14 and the optocoupler counter 16, for supplying power to the motor 19, the fault detector 14 and the optocoupler counter 16.

[0039] Furthermore, the walking component 1 also includes a first wireless module 5 and a central control module 6, which are respectively fixed at both ends of the mobile power supply 4; the first wireless module 5 is electrically connected to the central control module 6; the central control module 6 is electrically connected to the contactless fault detector 14 and the optocoupler counter 16; the central control module 6 is used to receive the fault point detected by the contactless fault detector 14 and the counting information of the optocoupler counter 16.

[0040] During use, when the contactless fault detector 14 detects a fault, the central control module 6 transmits the length of the fault point collected by the optical coupler counter 16 to the control component 2 through the first wireless module 5 .

[0041] In this embodiment, the layout of each part of the walking assembly 1 is reasonable, which makes full use of the space and has the advantages of small size and convenient carrying and use.

[0042] like Figure 1 and Figure 2 As shown, a third roller 43 is also connected to the inner side of the bottom support frame 11. The third roller 43 is arranged adjacent to and in parallel with the first roller 41 along the extension direction of the placement gap 13, and the third roller 43 is rotatably connected to the bottom support frame 11; a fourth roller 44 is also provided above the third roller 43. The fourth roller 44 is arranged adjacent to and in parallel with the second roller 42 along the extension direction of the placement gap 13, and the fourth roller 44 is rotatably connected to the movable frame 17.

[0043] Specifically, both ends of the rotating shaft of the third roller 43 penetrate the bottom support frame 11, and both ends of the rotating shaft of the fourth roller 44 penetrate the movable frame 17, so as to facilitate relative rotation.

[0044] In this embodiment, when the walking component 1 is used, two rollers are provided on the upper and lower sides of the wire 3, and the four rollers are of the same size and shape, which can ensure the stability of the walking component 1 when moving along the wire 3 and the accuracy of the detection data.

[0045] like Figure 3 As shown, the control component 2 includes a handle portion 21, on which a switch 22 is provided for starting and shutting down the control component 2; a display 23 is fixedly connected to the top of the handle portion 21, on which a total odometer 24 and a fault point odometer 25 are provided, and the display 23 has a second wireless module and a fixed power supply built in, the second wireless module is wirelessly connected to the first wireless module 5, and the fixed power supply is connected to the display 23 and the second wireless module to power both.

[0046] In this embodiment, the start and shut down of the component 2 is controlled by the switch 22, thereby controlling the connection and disconnection of the second wireless module and the first wireless module 5. The optocoupler counter 16 counts the number of rotations of the first roller 41, records the forward length of the walking component 1, and transmits it to the second wireless module through the central control module 6 and the first wireless module 5, and then displays it on the total odometer 24 on the display 23. At the same time, the contactless fault detector 14 performs fault detection. When a fault occurs, the central control module 6 transmits the length of the fault point to the second wireless module through the first wireless module 5, and then displays it on the fault point odometer 25 on the display 23, so that subsequent inspection and maintenance can be performed according to the records of the fault point odometer 25. In this process, wireless communication is used, data transmission is convenient, and the total odometer 24 and the fault point odometer 25 can accurately record the fault point.
