Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Please see Figures 1-8 This utility model provides a technical solution: a distribution network fault locator installation structure, including an adjustable telescopic rod 10, a drive assembly, a power source assembly, and a magnetic suction assembly. The upper end of the adjustable telescopic rod 10 is provided with a loading platform, and the distribution network fault locator is supported above the loading platform.

[0033] The loading platform includes a mounting cylinder 11 fixedly installed on the upper end of the adjustable telescopic rod 10, a bracket 12 fixedly installed on the upper surface of the mounting cylinder 11, and a limiting baffle 13 vertically fixedly installed on the front and back sides of the bracket 12. The bracket 12 and the limiting baffle 13 form a U-shaped support structure, which can support the power distribution fault locator.

[0034] The power distribution fault locator includes an openable upper cover 20 and a lower cover 21. The bottom of the lower cover 21 has a mounting groove, and the lower surface of the upper cover 20 has a threaded hole 22 corresponding to the mounting groove. A guide assembly is provided between the upper cover 20 and the lower cover 21. The guide assembly includes a guide post 60 fixed to the upper surface of the lower cover 21 and a guide groove 61 opened on the lower surface of the upper cover 20 and slidingly engaged with the guide post 60. The engagement of the guide post 60 and the guide groove 61 ensures smooth alignment during the opening and closing of the upper cover 20 and the lower cover 21. The opposing surfaces of the upper cover 20 and the lower cover 21 have mutually engaging clamping grooves 23. The inner surface of the clamping grooves 23 has anti-slip textures. When the upper cover 20 and the lower cover 21 are closed, they can clamp the cable.

[0035] The lower cover 21 integrates a signal acquisition module, a data processing module, and a wireless communication module. The wireless communication module is connected to the remote operation and maintenance platform. After the distribution network fault locator is fixed on the cable, the cable can be monitored using the distribution network fault locator (this technology is existing technology, so it will not be described in detail).

[0036] The magnetic attraction assembly includes an electromagnet 50 fixed on the upper surface of the platform, an embedding groove at the bottom of the lower cover 21, and a magnetic block 51 fixedly installed on the inner wall of the embedding groove. The polarity of the magnetic block 51 is attracted to the magnetic pole of the electromagnet 50 when it is energized. A battery 80 is provided inside the mounting cylinder 11. The bottom of the lower cover 21 of the distribution network fault locator is embedded into the U-shaped support structure of the bracket 12. Then, the distribution network fault locator can be stably fixed in the U-shaped support structure by the electromagnet 50 attracting the magnetic block 51, which achieves quick fixation and prevents the distribution network fault locator from shaking.

[0037] The drive assembly includes a threaded rod 30 rotatably mounted in a mounting groove via a bearing, a connecting plate 31 fixed to the lower end of the threaded rod 30, and four limiting pins 32 arranged in a circumferential array and fixed to the lower end of the connecting plate 31.

[0038] The power source assembly includes a motor 40 fixedly installed on the inner wall of the mounting cylinder 11, and a drive disk 41 connected to the output shaft of the motor 40. The drive disk 41 is located above the mounting cylinder 11. The upper surface of the drive disk 41 is provided with four arc-shaped limiting grooves 42 that cooperate with the limiting pins 32. The arc-shaped limiting grooves 42 on the drive disk 41 are constructed as arc-shaped slide structures, and their curvature matches the movement trajectory of the limiting pins 32.

[0039] After the power distribution fault locator is fixed in the U-shaped support structure, the limiting pin 32 will be inserted into the arc-shaped limiting groove 42. When the drive motor 40 drives the drive disk 41 to rotate, the arc-shaped limiting groove 42 will limit the limiting pin 32, thereby driving the threaded rod 30 to rotate accordingly, so that the upper cover 20 can be vertically raised and lowered along the guide post 60 to complete the clamping or release of the cable. After the power distribution fault locator is clamped on the cable, the electromagnet 50 is de-energized and demagnetized, and then the loading platform can be separated from the power distribution fault locator.

[0040] A camera 70 is provided at the upper end of the mounting cylinder 11. The camera 70 is positioned perpendicularly to the arc-shaped limiting groove 42 on the drive disk 41. The battery 80 is electrically connected to the motor 40, the camera 70 and the electromagnet 50 respectively. The camera 70 is wirelessly connected to the external display screen.

[0041] When the power grid fault locator needs to be removed, the adjustable telescopic rod 10 extends to drive the U-shaped support structure to contact the power grid fault locator. The camera 70 can be used to observe the relative position of the limit pin 32 and the arc-shaped limit groove 42. If the positions do not match, the motor 40 can be driven to rotate and change the position of the limit pin 32. When the positions of the limit pin 32 and the arc-shaped limit groove 42 are properly adjusted, the electromagnet 50 can be driven to attract the magnetic block 51. At this time, the limit pin 32 will be inserted into the arc-shaped limit groove 42. Then, the motor 40 is driven in reverse to release the top cover 20, realizing quick disassembly.

[0042] The adjustable telescopic rod 10 enables stepless adjustment of the installation height, adapting to different terrains and line erection requirements. The magnetic attraction between the electromagnet 50 and the magnetic block 51 provides a quick installation and removal function for the power distribution fault locator, eliminating the need for high-altitude climbing and reducing operational risks.

[0043] Specifically, the working principle and operation method of this utility model are as follows:

[0044] Height adjustment and positioning device fixation

[0045] The adjustable telescopic rod 10 can be used to raise and lower the cargo platform to the target height to adapt to different terrains or cable laying needs.

[0046] Magnetic fixing: The lower cover 21 of the distribution network fault locator is embedded into the U-shaped support structure of the loading platform. After the electromagnet 50 is energized, it attracts the magnetic block 51 at the bottom of the lower cover, realizing the rapid locking of the distribution network fault locator.

[0047] Drive linkage: Start motor 40, drive disk 41 to drive arc limit groove 42 to rotate, arc limit groove 42 limits limit pin 32, forcing connecting disk 31 and threaded rod 30 to rotate synchronously.

[0048] Opening and closing control: When the threaded rod 30 rotates, the upper cover 20 moves vertically up and down along the guide post 60. The guide groove 61 cooperates with the guide post 60 to ensure a stable movement trajectory. The cable is clamped or released by the anti-slip clamping groove 23. The anti-slip texture enhances friction and prevents the cable from slipping.

[0049] Real-time monitoring: The camera 70 is vertically aligned with the drive disk 41 to capture the meshing state of the limit pin 32 and the arc-shaped limit groove 42 in real time, ensuring that there is no misalignment during the drive process.

[0050] Remote operation and maintenance: The signal acquisition module inside the lower cover 21 monitors the cable status in real time, and the data is uploaded to the operation and maintenance platform via the wireless communication module to assist in fault location and diagnosis.

[0051] Quick disassembly: After clamping is completed, the electromagnet 50 is de-energized and demagnetized, and the loading platform is separated from the locator; during maintenance, the adjustable telescopic rod 10 is raised, the camera 70 assists in adjusting the position of the limit pin 32, and the magnetic suction component realizes the quick locking of the power grid fault locator and the loading platform. Then, the reverse drive motor 40 releases the top cover 20 to remove the locator.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
