Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electroscopes, in particular to a hanging high-voltage electroscope with a fixing ring. Background Art

[0002] A high-voltage electroscope is a specialized tool used to detect whether high-voltage electrical equipment is energized. In power systems, accurate use of the electroscope is crucial to ensuring worker safety and the proper operation of equipment. A high-voltage electroscope typically consists of a probe, an insulating rod, and other components. Its operating principle is to contact the high-voltage equipment with the probe, inducing an electric field and generating a signal to determine whether the equipment is energized. For high-voltage equipment of different voltage levels, a high-voltage electroscope of the corresponding specifications is required to ensure accurate and safe detection. In practical applications, the electroscope must possess excellent insulation performance, sensitivity, and reliability to accurately detect the presence of high voltage electricity in complex power working environments.

[0003] Existing high-voltage electrostatic test scenarios present several challenges. Conventional high-voltage electrostatic testers used in power operations in most regions of my country currently have the following specifications: a retracted length of approximately 380mm, an extended length of approximately 1000mm, an effective insulation length of approximately 700mm, a handle length of approximately 130mm, a telescopic insulating rod with approximately five sections, and a weight of approximately 400 grams. During operation, personnel must climb the pole to approximately 1.5 meters below the line, take safety precautions (wear a hard hat and safety belt when climbing, attach a personal safety lanyard upon reaching the operating position, and don insulating gloves) before removing the electrostatic tester for operation. This process involves extending the personnel's hands, making it difficult to grasp objects with insulating gloves. Lines that have not undergone electrical testing should be treated as live lines for operation. The safe testing distance for 10kV power is 0.7 meters. This testing procedure carries the risk of falling from height and electric shock. Furthermore, traditional electrostatic testers are relatively simple to operate, often requiring only manual operation with an insulating rod, lacking flexibility and versatility. In some complex working environments, it is impossible to meet the actual needs. Therefore, the art proposes a hanging high-voltage electroscope with a fixing ring to solve the above problem.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a hanging high-voltage electroscope with a fixing ring, including a sleeve 1 and a combination component. The sleeve 1 is the basic part of the entire device, and its inner side is slidably connected to the sleeve 2, the inner side of the sleeve 2 is slidably connected to the sleeve 3, the inner side of the sleeve 3 is slidably connected to the sleeve 4, and the inner side of the sleeve 4 is slidably connected to the slide bar 5. This nested design allows the entire device to be compactly stored together when not in use, making it easy to carry and store. The sleeve 1, sleeve 2, sleeve 3, sleeve 4 and slide bar 5 are all made of insulating carbon fiber. This material has excellent insulation properties and high strength, which can ensure safety during the electrical testing process. At the same time, the exposed length of each part is 1.5 meters. When all stretched and unfolded, the stacked length is exactly 7.5 meters, which can meet the needs of testing high-voltage electricity at high places. The top of the slide bar 5 is provided with an electrical testing component, which is used to test the existence of high voltage electricity. The electrical testing component includes an electrical tester body 6, and one end of the electrical tester body 6 is fixedly connected with a hook 7. This hook 7 can be conveniently hung at the electrical test ring for high-voltage electricity detection. The outer side of the electrical tester body 6 is fixedly connected with a data The data line 8 is used to transmit the signal detected by the electroscope body 6 to the external receiver connected to it, so that the state of the high voltage electricity can be known. The outer side of the sleeve 1 is fixedly connected to the limit block 9. One end of the data line 8 passes through the inner side of the limit block 9. The limit block 9 can fix the data line 8 to prevent the data line 8 from shaking during use. The interior of the sleeve 1, the sleeve 2, the sleeve 3, the sleeve 3 and the sleeve 4 are all provided with an L-shaped groove 10, and the inner side of the L-shaped groove 10 is provided with a groove 11. The outer sides of the sleeve 2, the sleeve 3, the sleeve 4 and the slide bar 5 are all fixedly connected with a fixed Column 12, the outer side of the fixed column 12 is slidably connected to the inner side of the L-shaped groove 10, and the outer side of the fixed column 12 is fitted with the inner side of the groove 11. Through this design, the sleeve 1 and the slide bar 5 can be pulled in opposite directions, so that the middle sleeve 2 2, sleeve three 3 and sleeve four 4 are all pulled out. At this time, each fixed column 12 is located at the corner of the corresponding L-shaped groove 10, and then it is rotated one by one so that the fixed column 12 enters the inner side of the groove 11. In this way, the sleeve 1 is erected, which can keep the five-section rod-shaped structure from the sleeve 1 to the slide bar 5 in a stretched state, providing stable support for the inspection of high voltage electricity.

[0025] Specifically, the sleeve 1 and the slide bar 5 can be pulled in opposite directions. During this process, due to the special connection method between the sleeves, the middle sleeve 2, sleeve 3, and sleeve 4 will be completely pulled out in turn. At this time, you can see that each fixing column 12 is accurately located at the corner of the corresponding L-shaped groove 10. Then, carefully rotate these fixing columns 12 one by one. As the rotation proceeds, the fixing columns 12 will gradually enter the inner side of the groove 11. In this way, when the sleeve 1 is erected, the five-section rod-shaped structure from the sleeve 1 to the slide bar 5 can be stably maintained in a stretched state. It is worth mentioning that the sleeve 1, sleeve 2, sleeve 3, sleeve 4, and slide bar 5 are all made of insulating materials with excellent insulation performance. The carbon fibers are carefully made, and their exposed length is 1.5 meters. When fully stretched and unfolded, the stacked length is 7.5 meters. This length is just right for accurately testing high-voltage electricity at high places. Then, the hook 7 at one end of the electroscope body 6 is firmly hung on the electroscope ring. At this time, the electroscope body 6 will quickly transmit the detected signal to the external receiver connected to the data line 8 through the data line 8. In this way, the staff will be able to know the status of the high-voltage electricity in time. Compared with the traditional method of staff climbing the pole to 1.5 meters below the high-voltage electricity for testing, this method of testing electricity is obviously safer and more reliable. It greatly reduces the risk of staff directly contacting high-voltage electricity and provides better protection for the life safety of staff.

[0026] Reference Figure 2-Figure 4 , the combination component is arranged on the outside of the electroscope body 6, and the combination component is used to assemble the electroscope body 6 with the external drone. The combination component includes two assembly frames 13, and the assembly frame 13 is arranged on the outside of the electroscope body 6. Two telescopic rods 14 are fixedly connected to the outside of the assembly frame 13. The telescopic rods 14 can be adjusted in length as needed to adapt to different drone support frame sizes. One end of the two telescopic rods 14 on the front and rear sides is fixedly connected with a nut 15. A stud is provided at one end of the electroscope body 6, and the nut 15 is threadedly connected to the outside of the stud. In this way, the assembly frame 13 can be firmly mounted on the electroscope body 6. The inner side of the assembly frame 13 is rotatably connected to two clamping jaws 16, and the outer side of the clamping jaws 16 is fixedly connected to a dial plate 17. By pressing the dial plate 17, the middle position of the two clamping jaws 16 can be opened, which makes it convenient to clamp the clamping jaws 16 on the support frame of the drone. A torsion spring 18 is sleeved on the rotating shaft of the two clamping jaws 16, and the two ends of the torsion spring 18 are respectively fixedly connected to the outer sides of the two clamping jaws 16. The torsion spring 18 can provide clamping force for the clamping jaws 16 to ensure that the clamping jaws 16 will not be easily loosened after clamping the drone support frame.

[0027] Specifically, the two nuts 15 can be accurately screwed onto the studs on the outside of the electroscope body 6 to ensure the firmness of the connection. Then, the two dial plates 17 can be gently pressed to slowly open the middle position of the two clamps 16. Then, the four sets of clamps 16 can be firmly clamped on the support frame of the drone. In order to ensure the stability of the drone during flight, the drone can be properly counterweighted. In this way, the entire electroscope can be smoothly lifted using a drone for electrical testing. This mode is particularly suitable for those staff who are proficient in operating drones. It provides a variety of ways for electrical testing operations. Whether it is testing electricity through a stretching sleeve or using a drone, it can better ensure the personal safety of the staff. This innovative design brings more convenience and safety to high-voltage electrical testing work.

[0028] Working principle: First, the sleeve 1 and the slide bar 5 can be pulled in opposite directions so that the middle sleeve 2 2, sleeve 3 3 and sleeve 4 4 ​​are all pulled out. At this time, each fixing column 12 is located at the corner of the corresponding L-shaped groove 10, and then they are rotated one by one so that the fixing column 12 enters the inner side of the groove 11. In this way, the sleeve 1 is erected, which can keep the five-section rod-shaped structure from sleeve 1 to slide bar 5 in a stretched state. Moreover, sleeve 1 1, sleeve 2 2, sleeve 3 3, sleeve 4 4 ​​and slide bar 5 are all made of insulating carbon fiber, and the exposed length is 1.5 meters, which is just the stacked length of 7.5 meters, which is just right for testing high voltage electricity. Hang the hook 7 on the test ring, and the tester body 6 will transmit the test signal to the external receiver connected to the data line 8 through the data line 8, so that the status of the high voltage electricity can be known. This method of testing electricity is safer than the staff climbing the pole to 1.5 meters below the high voltage electricity for testing electricity.

[0029] In addition, the two nuts 15 can be screwed onto the studs on the outside of the electroscope body 6, and then the two dial plates 17 can be pressed to open the middle position of the two clamps 16. The four sets of clamps 16 can be clamped on the support frame of the drone, and then the drone can be properly weighted. The drone can be used to lift the entire electroscope for electrical testing operations. This mode is suitable for staff who are proficient in operating drones, and provides a variety of ways for electrical testing operations, which can better ensure the personal safety of staff.
