Description

Technical Field

[0001] This utility model relates to the field of power distribution network monitoring technology, specifically a power distribution network fault location and monitoring device. Background Technology

[0002] The power distribution network fault location monitoring device is a specialized piece of equipment used to detect and locate line faults. It utilizes radar ranging principles, transmission line theory, and the principle of discontinuous reflection of media to accurately measure the time delay from the transmitted pulse to the reflected pulse and then automatically calculate the distance, thereby accurately locating the line fault. It can also measure the insulation resistance of the line to help determine whether there is a fault in the line and, to some extent, predict the insulation performance of the line.

[0003] In the existing technology, distance measuring and monitoring devices are usually connected to the line by crimping terminals to form a conductive path. However, when multiple sets of wires are connected, the wires will become tangled, affecting the stability of signal transmission. In addition, the contact area between the terminals and the wires is small, resulting in poor connection stability. The wires are easily loosened and detached due to external influences, which affects the normal use of the distance measuring and monitoring device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-6As shown, this utility model provides a technical solution: a power distribution network fault location monitoring device, including a monitoring device body 1, a first positioning frame 2, and a second positioning frame 3. A terminal block 11 is fixedly installed on the surface of the monitoring device body 1. A mounting base 12 and a mounting base 2 13 are fixedly installed on the surface of the monitoring device body 1 respectively. The first positioning frame 2 is rotatably connected to the mounting base 12, and the second positioning frame 3 is rotatably connected to the mounting base 2 13. A limit plate 14 is fixedly installed on the surface of the monitoring device body 1. A groove 201 is formed at the bottom of the first positioning frame 2, and a groove 301 is formed at the top of the second positioning frame 3. Cable trays 202 are formed at the bottom of the first positioning frame 2 and the top of the second positioning frame 3. Frames 4 are fixedly connected to the first positioning frame 2 and the top of the second positioning frame 3. The two frames 4 have the same structure. A guide rod 41 is fixedly connected to the bottom of one of the frames 4, and the bottom of the guide rod 41 is fixedly connected to the top of the first positioning frame 2. A toothed groove 42 is provided on one end of the inner side of the first positioning frame 2. A knob 5 is rotatably mounted on the surface of the first positioning frame 2. A threaded rotating rod 6 is rotatably mounted on the top of the frame 4. A connecting plate 61 is rotatably connected to the bottom of the threaded rotating rod 6. A connecting rod 62 is fixedly connected to the bottom of the connecting plate 61. A clamping block 63 is fixedly connected to the bottom of the connecting rod 62. A rotating plate 21 is rotatably mounted inside the groove 201. The bottom end of the rotating plate 21 extends downward to the outside of the groove 201. The two sides of the rotating plate 21 are respectively fixedly connected to... There is a spring 22 and a locking block 23. The side of the spring 22 is fixedly connected to the inner wall of the groove 201. The rotating plate 31 is rotatably installed inside the groove 301. The top of the rotating plate 31 extends upward to the outside of the groove 301. The two sides of the rotating plate 31 are fixedly connected to the spring 32 and the locking block 33 respectively. The side of the spring 32 is connected to the inner wall of the groove 301. The rear end of the knob 5 is fixedly connected to the push rod 51. The push rod 51 is rotatably installed inside the groove 201.

[0025] In this embodiment, the first positioning frame 2 and the second positioning frame 3 are connected to the mounting base 12 and the mounting base 13 respectively, so that the first positioning frame 2 and the second positioning frame 3 can rotate to adjust the angle. The first groove 201 and the second groove 301 are set thereto. The first spring 22 and the second spring 32 fix the angle of the first rotating plate 21 and the second rotating plate 31 respectively. At the same time, the first locking block 23 and the second locking block 33 abut against each other to make the first rotating plate 21 and the second rotating plate 31 rotate. The first locking block 23 and the second locking block 33 limit each other to allow the first positioning frame 2 and the second positioning frame 3 to be combined and connected. The wire harness grooves 202 at the upper and lower ends can separate and organize the wires, so that the connected wires can be neatly arranged and avoid excessive wire tangling, which would affect the stability of signal transmission. The limiting plate 14 can limit the angle of the first positioning frame 2 to prevent the first positioning frame 2 from sagging during connection and use, which would affect the normal connection of the wires.

[0026] Example 2

[0027] like Figures 1-6 As shown, the outer surface of the threaded rotating rod 6 is threadedly connected to the inner wall of the frame 4. The connecting plate 61 is slidably installed on the surface of the guide rod 41. The bottom end of the connecting rod 62 extends slidably inside the wire harness groove 202. The clamping block 63 is set inside the wire harness groove 202. The surface of the connecting plate 61 is provided with a sliding groove 611. A slider 64 is slidably installed inside the sliding groove 611. Both the front and rear ends of the slider 64 are fixedly connected with protrusions 65. A spring 66 is fixedly installed inside the connecting plate 61. One end of the protrusion 65 is fixedly connected to the side of the spring 66. The other end of the protrusion 65 extends outside the sliding groove 611, and the extended end of the protrusion 65 meshes with the toothed groove 42.

[0028] In this embodiment, the threaded rotating rod 6 is threadedly connected to the frame 4. Rotating the threaded rotating rod 6 allows the connecting plate 61 and the connecting rod 62 to move together. The guide rod 41 can limit the connecting plate 61, preventing it from rotating with the threaded rotating rod 6. The clamping block 63 is installed inside the wire harness groove 202 and moves to clamp and fix the wires inside the wire harness groove 202, improving the stability of the connection between the wires and the main body 1 of the monitoring device. This prevents the wires from loosening and falling off, which would cause the main body 1 of the monitoring device to malfunction. The toothed groove 42 provides one-way limit to the slider 64, preventing the connecting plate 61 from moving upward. This ensures the stability of the clamping block 63 during use and prevents the clamping block 63 from loosening due to the rotation of the threaded rotating rod 6 during monitoring. The protrusion 65 extends outward on the surface of the connecting plate 61. Pushing the protrusion 65 to make it slide will separate the slider 64 from the toothed groove 42, thereby releasing the one-way limit on the connecting plate 61.

[0029] Working principle: The wiring is fixed by crimping with terminal 11, allowing the main body of the monitoring device 1 to monitor the wiring. After the wiring is installed and connected, the first positioning frame 2 and the second positioning frame 3 are rotated inward simultaneously, causing them to contact each other. This combs multiple sets of wiring through the corresponding cable trays 202, separating and combing the wiring to prevent tangling due to excessive wiring. Simultaneously, when the first positioning frame 2 and the second positioning frame 3 are in contact, the locking blocks 23 and 33 gradually approach and press against each other, causing the rotating plates 21 and 31 to rotate under pressure. After the springs 22 and 32 return to their original positions... The first positioning frame 23 and the second positioning frame 33 are mutually limited, and the first positioning frame 2 and the second positioning frame 3 are connected and fixed. Then, by rotating the threaded rotating rod 6, the pressing block 63 is moved down to press and fix the line. The toothed groove 42 limits the slider 64 in one direction so that the connecting plate 61 cannot move upward, thus reinforcing the connected line and improving the stability during use. By rotating the knob 5, the push rod 51 is rotated and the rotating plate 21 and the rotating plate 31 are pushed. The first positioning frame 2 and the second positioning frame 3 can be separated by moving the first positioning frame 23 and the second positioning frame 3 away from each other, so that the main body 1 of the monitoring device can be disassembled and maintained later.
