Description

Technical Field

[0001] This utility model relates to the field of electrical variable measurement technology, specifically to an efficient insulator resistance detection device. Background Technology

[0002] In electrical variable measurement operations, measuring transmission lines involves measuring multiple electrical variables, including but not limited to voltage, current, impedance, and capacitance. Among these, the inspection of insulators is crucial. Insulators primarily support conductors and prevent current leakage; they can withstand mechanical loads and electrical stresses, ensuring the safe and stable operation of the power system. High-quality insulators reduce energy loss, prevent short circuits and grounding faults, improve transmission efficiency, and ensure grid reliability. However, with prolonged loads and exposure to high-altitude environments, including sunlight, wind, rain, and snow, insulators can experience resistance degradation, seriously threatening the operational safety of transmission lines. Therefore, periodic inspections are necessary. The insulator inspection industry commonly employs traditional manual inspection, combined drone-mounted robot inspection, and drone-mounted inspection with loads.

[0003] China Patent Network (patent publication number CN108896887B) discloses a tension insulator testing device and method, including a drone, a first camera, a processing module, a flight control system, sensors, and a testing device. The drone includes a drone body, an arm, a propeller, and landing gear. One end of the arm is connected to the drone body, and the other end is connected to the propeller. The landing gear is located at the bottom of the drone body. The first camera is located on the outside of the drone body. The processing module is used to receive the images captured by the first camera. The flight control system is used to receive the processing results of the processing module. The sensors are located on the drone body, and the testing device is connected to the drone body.

[0004] The above-mentioned testing method requires operating a drone to fly above the insulator, controlling the landing gear to be parallel to the insulator, and then controlling the drone to align its testing part with the insulator before automatically landing for testing. This testing method requires the drone to be very close to the insulator. In case of accidental discharge from the line, the drone may be damaged, leading to a crash, which poses a safety hazard. In addition, the testing process is not adjustable, and its applicability will be reduced if the insulator installation angle is different. Therefore, we propose a high-efficiency insulator resistance testing device. Utility Model Content

This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this invention is to provide an efficient insulator resistance detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency insulator resistance detection device, comprising a drone body, a mounting bracket threadedly fixed to the bottom end of the drone body, a detection component fixed to the bottom end of the mounting bracket, the detection component comprising a first insulating rod, an electrical control box connected to one end of the first insulating rod, a charging port plug and a switching port plug respectively installed on one side of the electrical control box, a second insulating rod inserted into the inner hole of the other end of the first insulating rod, and an insulating rod connector sleeved at the connection between the first insulating rod and the second insulating rod, a scale plate fixed to one end of the second insulating rod, and a probe bracket attached to one side of the scale plate, probe inserts fixed to both sides of the front end of the probe bracket, and a probe inserted into one end of the probe insert.

[0011] Furthermore, the gimbal housing is fastened to the bottom of the gimbal bracket via a quick connector, and a control board and a communication antenna are installed inside the gimbal housing.

[0012] Furthermore, the mounting frame includes a belly mounting plate, and the top surface of the belly mounting plate is threaded to the bottom belly of the UAV body. Shock absorbers are connected around the bottom surface of the belly mounting plate, and the bottom end of the shock absorbers is connected to an upper carrier connecting plate.

Pipe clamps are connected to the two sides of the bottom end of the pipe rack, and a first insulating rod is fastened to the inner wall of the pipe clamp.

[0013] Furthermore, the pipe clamp is fixedly connected to the upper connecting plate of the carrier through the pipe hanger frame, and the pipe clamp is fastened to the middle section of the first insulating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The probe bracket in this testing device can be rotated and adjusted according to the different installation methods of the insulator strings during testing, to ensure tight contact between the probe and the steel caps at both ends of the insulator. In addition, if the probe accidentally gets stuck on the insulator sheet during testing, the drone can increase its power and fly backward to pull out the probe, reducing the risk of crash. At the same time, it can be connected with the pipe rack of the insulating material to further improve the safety of the testing process and reduce safety hazards such as puncture.

[0029] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0030] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] This utility model provides, for example Figure 1-7The device for high-efficiency detection of insulator resistance shown includes a drone body 1, a mounting bracket 2 is threadedly fixed to the bottom end of the drone body 1, a detection component 3 is fixed to the bottom end of the mounting bracket 2, the drone body 1 includes a drone 101, and a gimbal shell 102 is provided on one side of the bottom of the drone 101, a quick connector 103 is connected to the top end of the gimbal shell 102, and a gimbal bracket 104 is connected to the top end of the quick connector 103.

[0032] To provide a stable wireless control process and reduce detection operations, such as Figure 1 As shown, this detection device structure is wiredly connected to the gimbal housing 102 mounted on the gimbal bracket 104 via the drone 101. Communication is achieved through this wired connection, and the issuance of control tasks and feedback of detection results are all displayed on the drone remote controller. This allows for full integration of information, eliminating the need for an additional remote controller for detection, thus reducing costs and operational complexity. Communication with the detection component 3 is achieved wirelessly via the control board and communication antenna inside the gimbal housing 102, preventing external high voltage from entering the drone and destroying it, thereby improving operational safety.

[0033] like Figure 2 As shown, the mounting frame 2 includes a belly mounting plate 201, and the top surface of the belly mounting plate 201 is threaded to the bottom belly of the UAV body 1. Shock absorbers 202 are connected around the bottom surface of the belly mounting plate 201. The bottom end of the shock absorber 202 is connected to the upper connecting plate 203 of the carrier. The bottom end of the upper connecting plate 203 of the carrier is connected to the pipe rack 204. The lower connecting plate 205 of the carrier is fixed between the inner walls on both sides of the pipe rack 204. The bottom ends of the pipe rack 204 are connected to the pipe clamps 206. The inner wall of the pipe clamps 206 is fastened with a first insulating rod 301.

[0034] To maintain stability during the connection and flight control process, such as Figure 2 As shown, the structure of this testing device features a pipe clamp 206 installed in the middle of the first insulating rod 301. The clamp is installed in a semi-open manner, which facilitates the assembly and disassembly of the insulating rod. At the same time, the pipe clamp 206, the pipe frame 204, and the connecting plate 203 on the carrier are fixedly connected together, improving the overall rigidity and structural stability. The connecting plate 203 on the carrier is connected to the fuselage mounting plate 201 through a shock absorber 202, which prevents the overall vibration of the testing component 3 from being transmitted to the UAV 101 during the testing process, thus avoiding any impact on the flight attitude of the UAV 101. In addition, the pipe clamp 206 on the first insulating rod 301 is the center of gravity of the entire testing system, thereby reducing the power consumption of the UAV for stabilization and improving flight stability. The pipe frame 204 is also made of insulating material to prevent external high voltage from being transmitted to the testing component 3 and penetrating the UAV 101 along the pipe frame 204, causing a crash.

[0035] like Figure 3-7As shown, the detection component 3 includes a first insulating rod 301. One end of the first insulating rod 301 is connected to an electrical control box 302. A charging port plug 303 and a switch port plug 304 are respectively installed at the charging port and switch port on one side of the electrical control box 302. A second insulating rod 305 is inserted into the inner hole of the other end of the first insulating rod 301. An insulating rod connector 306 is sleeved at the connection between the first insulating rod 301 and the second insulating rod 305. A scale 307 is fixed to one end of the second insulating rod 305. A probe bracket 308 is attached to one side of the scale 307. Probe inserts 309 are fixed to both sides of the front end of the probe bracket 308. A probe 310 is inserted into one end of the probe insert 309.

[0036] Finally, to further improve the safety and adjustability of the detection process, such as... Figure 3-7 As shown, the probe bracket 308 of this testing device is fixed to the head end of the second insulating rod 305 by a clamping method. A scale line is provided on the upper rear side of the probe bracket. A scale 307, which is mounted next to the second insulating rod 305, allows the probe bracket 308 to rotate according to the reading on the scale 307 after the clamping screw is loosened. Depending on the installation method of the insulator string during testing, the probe bracket 308 is rotated and adjusted according to the scale 307 to ensure tight contact between the probe 310 and the steel caps at both ends of the insulator. Furthermore, each probe 310 is equipped with a probe clamp in the middle section, reducing the length of the probe cantilever beam, thereby improving the rigidity of the probe 310, reducing vibration amplitude, and facilitating operation. Each probe 310 has an "eight"-shaped tip, which serves as a guide when it comes into contact with the insulator during operation, improving the error tolerance of the pilot's operation. The end of the probe 310 is embedded in the probe plug 309 by an irregular bending method. The probe 310 is inserted and removed by elastic deformation, which facilitates the installation of the probe 310. If the probe 310 is accidentally stuck on the insulator sheet, the UAV 101 can increase its power and fly backward to pull out the probe 310, reducing the risk of crash. The probe plug 309 has holes on the inside, which allow the wires inside the probe bracket 308 to contact the end of the probe 310, so that the probe 310 can be connected to the board in the control box 302 for stable testing.

[0037] In summary, the structure of this testing device, during use, firstly, the gimbal housing 102 containing the control board and communication antenna is installed on the gimbal bracket 104. The entire testing component 3 is fixed to the belly of the UAV via the belly mounting bracket 2. The second insulating rod 305 is pulled out from the first insulating rod 301 to a suitable length, and the screws of the insulating rod connector 306 are tightened to fix the two insulating rods together. Then, the probe 310 is inserted into the probe plug 309. Depending on the different operating scenarios and the installation method of the insulator, the probe bracket 308 is rotated so that the two probes 310 and the insulator string are always kept on the same horizontal line. When testing the tension horizontal insulator string, the probe bracket 308 is kept horizontal, and the probe 310 is in close contact with the steel caps on both sides of the insulator for testing. When testing the suspension insulator string, the probe bracket 308 is rotated 90 degrees to keep it vertical, and the probe 310 is in close contact with the steel caps at the top and bottom ends of the insulator for testing.

[0038] After preparation, the detection system is switched on, and the pilot controls the detection unit via the drone remote controller and control system to begin operation. The pilot then controls the drone to take off, carrying the device, and flies to the vicinity of the insulator. Two probes contact the steel caps at both ends of the insulator. Upon contact, the device automatically performs the detection and displays the measured values ​​in real-time on the remote controller. Simultaneously, the drone's video recording function is activated, capturing the appearance of the target insulator. When the insulator resistance falls below the set threshold, an audible and visual alarm will sound on the remote controller to notify the pilot.
