Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) voltage testing, specifically a UAV voltage testing device for power grid transmission lines. Background Technology

[0002] As the "main artery" of power transmission, the safe and stable operation of power grid transmission lines is crucial for ensuring electricity supply for social production and daily life. Voltage testing, a key step in determining whether a line is energized and preventing electric shock accidents, suffers from problems such as low efficiency, high risk, and significant limitations imposed by terrain and environment, thanks to traditional manual methods. With the development of drone technology, drone voltage testing is gradually becoming the mainstream trend; however, existing drone voltage testing devices still have many shortcomings that urgently need to be addressed.

[0003] On the one hand, existing UAV voltage testing devices lack sufficient testing angle and scene adaptability. Most UAVs only have a voltage testing interface in a single location on the fuselage, which limits voltage testing operations to approaching from below the transmission line and makes it difficult to cope with complex line installation environments. On the other hand, the feedback and confirmation mechanism of voltage testing results is flawed. Traditional UAV voltage testing devices mostly rely on the sound and light signals of the testing equipment itself to display results. When the UAV flies at a high altitude or when there is significant ambient light or noise interference, ground operators have difficulty clearly observing or identifying the sound and light signals, making it difficult to confirm the voltage testing results. Therefore, it is necessary to design a UAV voltage testing device for power grid transmission lines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a UAV voltage testing device for power grid transmission lines to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a UAV voltage testing device for power grid transmission lines, comprising a UAV body, wherein mounting interfaces are fixedly installed on the top and bottom of the UAV body, a voltage detector body is provided inside the mounting interface, and a connecting rod is fixedly installed on the surface of the voltage detector body;

[0006] A limiting plate is fixedly installed on the surface of the electroscope body, and limiting mechanisms are provided on both sides of the top and bottom of the drone body.

[0007] Preferably, the limiting mechanism includes a sliding sleeve, four of which are fixedly connected to the top and bottom sides of the UAV body respectively. A sleeve is slidably connected inside the sliding sleeve, and a traction plate is fixedly installed at one end of the sleeve. Limiting buckles that cooperate with the limiting plate are fixedly installed on the front and rear sides of one side of the traction plate.

[0008] Preferably, both sides of the UAV body are rotatably connected to rotating plates via bearing components, a spring is welded to one side of the inner cavity of the sleeve, and a limit rod is welded to one end of the spring.

[0009] Preferably, one end of the limiting rod passes through the rotating plate and extends into the interior of the rotating plate.

[0010] Preferably, the upper and lower sides of one side of the rotating plate are provided with limiting grooves that cooperate with the limiting rod.

[0011] Preferably, an audible and visual alarm device is fixedly installed on both the top and bottom of the drone body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This UAV voltage testing device for power transmission lines, by setting mounting interfaces, voltage detector bodies, and connecting rods at both the top and bottom of the UAV body, enables the UAV body to perform voltage testing from both below and above, improving scene adaptability. When it is necessary to disassemble and replace the voltage detector body and connecting rod, the limiting rod can be pressed. After the limiting rod is pressed, it can disengage from the rotating plate. Then, by rotating the rotating plate, the sleeve can be pulled. The movement of the sleeve drives the traction plate and the limiting buckle to move. After the traction plate and the limiting buckle move, they no longer limit the limiting plate. At this time, it is convenient to disassemble and replace the voltage detector body and connecting rod.

[0014] 2. The UAV voltage testing device for power transmission lines is equipped with an audible and visual signal alarm. The alarm can receive signals, which are then received by a ground receiver to confirm the voltage testing results. The device can also be used for secondary confirmation through its own audible and visual signals, thus improving the convenience of confirming the voltage testing results.

[0021] 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.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a UAV voltage testing device for power grid transmission lines, including a UAV body 1. The top and bottom of the UAV body 1 are fixedly installed with mounting interfaces 2. The mounting interface 2 is provided with a voltage detector body 3 inside. The surface of the voltage detector body 3 is fixedly installed with a connecting rod 4.

[0024] Specifically, a limiting plate 5 is fixedly installed on the surface of the electroscope body 3. Limiting mechanisms are provided on both sides of the top and bottom of the drone body 1. The limiting mechanisms include sliding sleeves 6, of which four are provided and fixedly connected to the top and bottom sides of the drone body 1 respectively. A sleeve 7 is slidably connected inside the sliding sleeve 6. A traction plate 8 is fixedly installed at one end of the sleeve 7. Limiting buckles 9 that cooperate with the limiting plate 5 are fixedly installed on the front and rear parts of one side of the traction plate 8. Rotating plates 10 are rotatably connected to both sides of the drone body 1 through bearing components. A spring 11 is welded to one side of the inner cavity of the sleeve 7. A limiting rod 12 is welded to one end of the spring 11. One end of the limiting rod 12 passes through the rotating plate 10 and extends into the interior of the rotating plate 10. Limiting grooves 13 that cooperate with the limiting rod 12 are opened on the upper and lower sides of one side of the rotating plate 10. By setting mounting interfaces 2, voltage detector bodies 3, and connecting rods 4 at both the top and bottom of the drone body 1, the drone body 1 can perform voltage testing from both below and above, improving scene adaptability. Furthermore, the setting of limiting buckles 9 facilitates the fixation of the two voltage detector bodies 3 and connecting rods 4. When it is necessary to remove and replace the voltage detector bodies 3 and connecting rods 4, the limiting rod 12 can be pressed. After the limiting rod 12 is pressed, it can disengage from the rotating plate 10. Then, by rotating the rotating plate 10, the rotating plate 10 is no longer in contact with the sleeve 7. At this time, the sleeve 7 can be pulled. The movement of the sleeve 7 drives the traction plate 8 and the limiting buckle 9 to move. After the traction plate 8 and the limiting buckle 9 move, they no longer limit the limiting plate 5. At this time, it is possible to remove and replace the voltage detector bodies 3 and connecting rods 4.

[0025] Among them, the top and bottom of the UAV body 1 are fixedly installed with sound and light to electrical signal alarm 14. By setting the sound and light to electrical signal alarm 14, the signal can be received through the sound and light to electrical signal alarm 14, and then the signal can be received through the ground receiver to confirm the voltage test result. At the same time, the sound and light signal of the voltage tester body 3 itself can be used for secondary confirmation, which improves the convenience of confirming the voltage test result.

[0026] Working Principle: This utility model is a UAV voltage testing device for power grid transmission lines. By setting mounting interfaces 2, voltage detector bodies 3, and connecting rods 4 at both the top and bottom of the UAV body 1, the UAV body 1 can perform voltage testing from both below and above, improving scene adaptability. Furthermore, the setting of limiting buckles 9 facilitates the fixation of the two voltage detector bodies 3 and connecting rods 4. When it is necessary to remove and replace the voltage detector bodies 3 and connecting rods 4, the limiting rod 12 can be pressed. After the limiting rod 12 is pressed, it can disengage from the rotating plate 10. Then, by rotating the rotating plate 10... This prevents the rotating plate 10 from contacting the sleeve 7. At this point, the sleeve 7 can be pulled, and the movement of the sleeve 7 will cause the traction plate 8 and the limit buckle 9 to move. After the traction plate 8 and the limit buckle 9 move, they will no longer limit the limit plate 5. This makes it easier to remove and replace the voltage detector body 3 and the connecting rod 4. At the same time, by setting up an audible and visual electrical signal alarm 14, the signal can be received through the audible and visual electrical signal alarm 14. Then, the signal can be received through the ground receiver to confirm the voltage detection result. At the same time, the voltage detector body 3 can also be used for secondary confirmation through its own audible and visual signals, which improves the convenience of confirming the voltage detection result.
