[0042] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] Example 1:

[0044] The present invention provides a distribution line fault location device, such as Figure 1As shown, the device comprises a main body 1 and a positioning assembly. The main body 1 comprises an end cap 12, while the positioning assembly 2 comprises a rotating member 21, a connecting member 22, a fixed platform 23 fixed axially below the connecting member 22, and a positioning rod 24 connected to the fixed platform 23. The rotating member 21 further comprises a threaded rod 211 that is rotatable relative to the end cap 12, and the connecting member 22 is movably connected to the threaded rod 211 via threads. When the threaded rod 211 rotates relative to the end cap 12, the connecting member 22, driven by the threads, moves along the direction in which the threaded rod 211 extends, thereby driving the fixed platform 23 to move along the direction in which the threaded rod 211 extends, thereby moving the positioning rod 24.

[0045] In this embodiment, the threaded rod 211 is horizontally arranged on the end cover 12, that is, the positioning rod 24 can move in the horizontal direction, thereby adapting to different fault locations. Moreover, when moving the positioning rod 24, it is only necessary to rotate the threaded rod 211 in situ, which has the advantages of saving time and effort, and can also reduce the volume of the positioning device.

[0046] Furthermore, the connecting member 22 includes a first slider 221 and a telescopic rod 222. The first slider 221 is sleeved onto the threaded rod 211, and the first slider 221 and the threaded rod 211 are threadedly sleeved together. A fixed rod 222a is connected to the lower end of the telescopic rod 222, wherein the fixed rod 222a is used to be fixedly connected to the fixed platform 23. When the fixed platform 23 needs to be moved vertically, the electrically controlled telescopic rod 222 can be simply activated to move axially. This enables the positioning rod 24 to move horizontally and vertically, broadening the application areas of the positioning device. To ensure the stability of the fixed platform 23 during the telescopic movement of the telescopic rod 222, prevent the fixed platform 23 from swinging, and ensure smooth movement, two telescopic rods 222 are provided in this embodiment. One end of each telescopic rod 222 is fixedly connected to the connecting member 22, and the other end of each telescopic rod 222 is fixedly connected to the fixed rod 222a.

[0047] Specifically, a first groove 121 is provided on the lower surface of the end cap 12, and both ends of the threaded rod 211 are rotatably fixed to the side walls of the first groove 121 via bearings 3. A first through-hole 122 is provided on the end cap 12, and the first through-hole 122 is located within the first groove 121. The rotating member 21 also includes a motor 123, a first gear 124, and a second gear 125 located on the upper surface of the end cap 12. Parts of the first gear 124 and the second gear 125 are located within the first through-hole 122, and the first gear 124 is sleeved on the output shaft of the motor 123, while the second gear 125 is sleeved on the threaded rod 211 and meshes with the first gear 124. When the motor 123 provides rotational power to the first gear 124, the first gear 124 drives the second gear 125 to rotate, and the second gear 125 drives the threaded rod 211 to rotate, thereby realizing the horizontal movement of the positioning rod 24. In this embodiment, the movement of the positioning rod 24 in the horizontal direction is achieved through the transmission of force, which reduces the volume of the positioning device and facilitates operation.

[0048] Furthermore, a second groove 126 is provided in the first groove 121, wherein the second groove 126 is provided at the top of the first groove 121, and the width of the second groove in the horizontal direction is smaller than that of the first groove 121. A limit block 223 is also fixed axially above the first slider 221, and a portion of the limit block 223 is inserted into the second groove 126. When the first slider 221 moves along the threaded rod 211, a portion of the limit block 223 moves in the second groove 126, ensuring the linear movement of the first slider 221. When the limit block 223 moves to the horizontal edge of the second groove 126, a portion of the limit block 223 abuts against the side wall of the second groove 126, thereby preventing the first slider 221 from moving further, thereby performing a limiting function, preventing the fixed platform 23 from touching the positioning device during movement, and protecting the safety of the device. It should be noted that the "displacement" referred to in the present invention refers to the displacement of the first slider 221 on the threaded rod 211.

[0049] In this embodiment, if Figure 2As shown, the device body 1 also includes two support legs 13 for supporting and fixing the end cover 12. Furthermore, the two support legs 13 each include a first support leg 131, a second support leg 132 and a latch 133. The first support leg 131 is fixed to the lower surface of the end cover 12, and a pulley 14 is also fixed to the end of the first support leg 131 away from the end cover 12, and a first positioning hole 15 is provided on the side wall of the first support leg 131 near the pulley 14. The second support leg 132 is designed as a hollow structure, and a plurality of second positioning holes 16 of different heights are provided along the axial direction of the second support leg 132. At least a portion of the first support leg 131 can be inserted into the second support leg 132, and the pulley 14 abuts against the side wall of the second support leg 132 and can slide along the inner side wall of the second support leg 132. When the height of the end cover 12 needs to be changed, the first support leg 131 only needs to be slid up and down along the second support leg 132, and the pulley 14 can reduce the force during sliding; when the first support leg 131 needs to be fixed, the pin 133 is passed through the second positioning hole 16 and the first positioning hole 15 in sequence. Furthermore, in order to ensure the firmness of the fixation between the first support leg 131 and the second support leg 132, a plurality of third positioning holes 17 are provided on the inner side wall of the second support leg 132, and the plurality of third positioning holes 17 are respectively aligned with the plurality of second positioning holes 16. The pin 133 can be inserted into the third positioning hole 17 through the first positioning hole 15, thereby ensuring the stability of the first support leg 131. In this embodiment, the plurality of second positioning holes 16 can enable the end cover 12 to adapt to different heights, so that the positioning device can be placed at an appropriate height when the distribution line is being repaired. In this embodiment, the surface of the pin 133 has external threads, and the corresponding first positioning hole 15, second positioning hole 16 and third positioning hole 17 all have internal threads. The threaded fixation can further ensure the stability between the first support leg 131 and the second support leg 132.

[0050] Further, such as Figure 3As shown, the fixing platform 23 also includes a fixing seat 231, a first curved block 232, a second curved block 233, a second slider 242, and a threaded fastener 4. The positioning rod 24 is connected to the bottom of the second slider 242, and an arc-shaped gap 28 is defined between the first curved block 232 and the second curved block 233. Specifically, the first curved block 232 is provided with a plurality of first threaded holes 25, which are spaced apart on the first curved block 232. The second curved block 233 is provided with a second through-hole 26, and the second slider 242 is provided with a third threaded hole 27. The positioning rod 24 passes through the second through-hole 26 and is fixedly connected to the second slider 242 located within the arc-shaped gap 28. The threaded fastener 4 can pass through the first threaded hole 25 and the third threaded hole 27 and firmly abut the second slider 242 against the second curved block 233, preventing the second slider 242 from moving within the arc-shaped gap 28, thereby securing the positioning rod 24. When the angle of the positioning rod 24 needs to be adjusted, the threaded fastener 4 can be loosened from the third threaded hole 27 and removed from the third threaded hole 27. At this time, the position of the second slider 242 in the arc-shaped gap 28 can be adjusted, so that the positioning rod 24 and the second slider 242 move in the arc-shaped gap like a pendulum. The threaded fastener 4 is then passed through the other first threaded hole 25 and tightened into the third threaded hole 27, thereby fixing the second slider 242 and tilting the positioning rod 24 to a certain angle. This combination allows the angle of the positioning rod 24 to be adjusted, broadening the scope of use.

[0051] Example 2:

[0052] The difference from the first embodiment is that the first arc block 233 is provided with a fourth through-hole, and at the same time, two locking blocks that can extend out of the second slider 242 are movably embedded on the second slider 242. The parts of the two locking blocks extending out of the second slider 242 can respectively contact and abut against the first arc block 232 and the second arc block 233. The locking blocks are arranged to face each other on a side that extends into the second slider 242, and a semi-inverted conical arc groove is provided on the surface. The third threaded hole 27 on the second slider 242 is designed to be connected to the semi-inverted conical arc groove in the direction of the rotation. So that one end of the threaded fastener 4 can extend between the two semi-inverted conical arc grooves. When the dynamic threaded fastener 4 causes one end of the threaded fastener 4 to extend between the two semi-inverted conical arc grooves, one end of the threaded fastener 4 contacts and abuts against the inner wall of the semi-inverted conical arc groove, and the spacing between the semi-inverted conical arc grooves is increased, thereby increasing the length of the locking block extending out of the second slider 242, so that the extended part can contact and abut against the first arc block 232 and the second arc block 233 respectively, thereby completing the locking block of the second slider 242 and the first arc block 232 and the second arc block 233. In this way, the positioning rod 24 can be infinitely adjusted, which is more suitable.

[0053] When the second slider 242 is moved, in order to reduce the friction resistance between the second slider 242 and the second arc block 233 and the first arc block 232 , moving wheels 29 are further provided at the upper and lower ends of the second slider 242 .

[0054] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
