[0002] In order to prevent damage caused by lightning strikes, lightning protection facilities are usually installed on buildings or structures. In order to ensure that lightning protection facilities work effectively in the long term, they need to be professionally inspected regularly. Traditional lightning protection inspections are mostly done by manually carrying test wires, that is, inspectors carry test wires to the top of the building to conduct lightning protection inspections on the building's lightning protection facilities, such as roof lightning strips and lightning rods. This detection method cannot detect high-risk locations, and the detection process is cumbersome, dangerous, inefficient, and labor-intensive for inspectors, which consumes a lot of manpower and material resources.

[0003] In order to solve the above problems, the industry has begun to use drones to carry test lines to conduct lightning protection inspections on lightning protection facilities such as lightning rods. Using drones to carry test lines to conduct lightning protection inspections can greatly improve inspection efficiency, reduce labor costs and work intensity, and improve safety factors. However, the current lightning protection inspection equipment based on drones still has the following problems: During the inspection process, the inspection components, such as the inspection end of the test line, need to be connected to the lightning rod. For the connection between the inspection end of the test line and the lightning rod, the inspection end of the test line can only be magnetically sucked to the lightning protection facility, such as the lightning rod, after the drone flies to the approximate position. However, the connection between the test line and the lightning rod using the magnetic connection method is not reliable, easy to loosen, virtual connection, and there are also fixed requirements for the material of the lightning rod, which affects the effectiveness of lightning protection inspection of the lightning rod.

[0037] In order to more clearly demonstrate the objectives, technical solutions and advantages of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] Figure 1 FIG. 1 is a schematic diagram of the structure of the lightning protection rod detection connection device of this embodiment. Figure 1 As shown, the connecting device comprises a sleeve 1 and a connecting mechanism 2 connected to the sleeve 1;

[0040] The sleeve 1 is used to be sleeved on the lightning rod 6. Figure 3 , Figure 4 1 is a structural diagram of a lightning rod connection and detection using the lightning rod detection and connection device according to an embodiment of the present invention; Figure 3 , 4 As shown, when the connection device is used to perform lightning protection testing on the lightning rod 200, the connection device is carried by a drone to cover the sleeve 1 on the lightning rod 200.

[0041] The connection mechanism 2 includes a conductive member 21 and a motor 22 for driving the conductive member 21 to move. The motor 22 has a brush 221 conductively connected to the conductive member 21 . The brush 221 is conductively connected to the test line 300 .

[0042] In this embodiment, a part of the conductive member 21 is arranged inside the sleeve 1, and the part of the conductive member 21 inside the sleeve 1 can be electrically connected to the lightning rod 6. Since the lightning rod is exposed to the outdoors for a long time, a rust layer is easily formed on its surface; some lightning rods are coated with anti-corrosion and anti-rust insulating paint on their surfaces to prevent rust. In order to further ensure the reliability of the connection between the conductive member and the lightning rod, and prevent the rust layer, anti-corrosion and anti-rust insulating paint and other insulating layers on the surface of the lightning rod from affecting the effectiveness of the connection, the conductive member 21 can remove the rust, insulating paint and other insulating layers on the surface of the lightning rod 6 and the part connected to it when moving.

[0043] During the test, after the drone 400 puts the sleeve 1 on the lightning rod 200, the conductive member, driven by the motor, removes the insulating layer of the surface of the lightning rod 200 and its connecting parts through movement, and then the conductive member can form an effective connection with the lightning rod 200. Since the conductive member is also conductively connected to the brush of the motor, and the brush is conductively connected to the test end of the test line 300 during the test, the ground end of the test line is connected to the ground resistance tester 500 and other ground detection equipment. In this way, the ground resistance tester 500 and other ground detection equipment can be connected to the lightning rod at high altitude through the connection device, so as to perform electrical path testing.

[0044] It should be noted that when performing lightning rod inspection, the ground resistance tester 500 is set on the ground, one end of which is connected to the end of the test line 300 opposite to the test end; the other end is connected to the nearby soil outside the building ground grid (for example, connected to two grounding iron rods inserted into the nearby soil outside the building ground grid, not shown in the figure), so as to form a closed loop, namely: lightning rod 200-down conductor (not shown in the figure)-grounding part at the bottom of the building-nearby soil outside the building ground grid-ground resistance tester 500, so as to achieve the purpose of detecting the grounding resistance of the lightning rod 200 at the top of the building (the grounding resistance of the building grounding body and the soil).

[0045] In order to facilitate the control of the UAV, the sleeve is put on the lightning rod, so that the sleeve can pick up the lightning rod in the air. Figure 1 As shown, the sleeve 1 is in a conical funnel shape, and its diameter gradually increases from top to bottom. The larger opening at the lower end is conducive to the sleeve finding the position of the lightning rod when it is sleeved. Further, the upper end of the sleeve 1 is closed, and it can be sleeved on the top of the lightning rod 6. The sleeve with a closed upper end is conducive to the sleeve being buckled on the top of the lightning rod in the form of a cap-type sleeve, which is conducive to fixing the relative position between the sleeve and the lightning rod.

[0046] Furthermore, the sleeve 1 can be fixedly connected to the lightning rod. For example, the sleeve forms an interference fit with the outer surface of the lightning rod at its minimum diameter. The fixed connection between the sleeve and the lightning rod can make the connection between the connecting device and the lightning rod more reliable and effective.

[0047] Furthermore, a spring 11 is installed on the inner surface of the closed end of the sleeve 1 (the closed end in this embodiment is the upper end), and when the sleeve 1 is sleeved on the top end of the lightning rod 6, the spring 11 can form compression between the top end of the lightning rod 6 and the closed end of the sleeve. With such an arrangement, when the sleeve is removed from the lightning rod after the test, the spring can exert a downward force on the sleeve, so that the entire connection device is easy to detach from the lightning rod.

[0048] Further, such as Figure 1 As shown, the conductive member 21 is a steel file, one end of which is connected to the output end of the motor 22, and the steel file is conductively connected to the brush. The motor 22 can drive the steel file to rotate with its own axis as the rotating axis. The sleeve 1 has an opening, and part of the file surface of the steel file extends into the sleeve 1 through the opening. When the sleeve 1 is sleeved on the lightning rod 6, the steel file can be conductively connected to the lightning rod 6, and the steel file can remove the insulating layer on the surface of the lightning rod 6 when rotating.

[0049] Furthermore, in order to reduce the motor speed, the output end of the motor 22 is connected to the steel file through a reducer 23. Figure 1 As shown, the reducer of this embodiment is a turbine worm reducer.

[0050] In order to facilitate the control of the connection mechanism 2, the connection mechanism 2 further includes a remote control mechanism, which is used to remotely control the start and stop of the motor 22. This arrangement allows the staff on the ground to drive the front steel file through the remote control motor to remove the insulation part of the lightning rod and achieve effective connection with the lightning rod.

[0051] Further, such as Figure 1 , 2 As shown, the remote control mechanism includes a controller 241 and a remote controller 242 connected to the controller 241 by signal. The controller 241 is connected to the sleeve 1 and the controller 241 is connected to the motor 22 by line. When in use, the remote controller 242 sends a control signal to the controller 241. The controller 241 controls the start or stop of the motor 22 according to the control signal sent by the remote controller 242. When the motor 22 starts, the conductive parts such as the steel file in the connection mechanism start to move to remove the insulating layer on the surface of the lightning rod and effectively connect with the lightning rod. Such a setting allows the staff to control the connection mechanism on the ground through the remote controller.

[0052] In order to better install the connection mechanism on the sleeve 1, the connection mechanism 2 further includes a fixing platform 25, such as Figure 1 As shown, the fixed platform 25 is fixedly connected to the outer surface of the sleeve 1 , and the motor 22 , the reducer 23 and the controller 241 are installed on the fixed platform 25 .

[0053] In order to facilitate the drone to carry the connecting device and reduce the load burden of the drone, and also to prevent the ground resistance tester from outputting a large current to the test line during work and burning out the motor, further, the sleeve 1 and the reducer 23 are both made of plastic insulating material.

[0054] In order to facilitate monitoring of the rust condition of the lightning rod, the rust and paint removal of the connection mechanism, and the connection condition, the connection device further includes a remote monitoring mechanism 3, and the remote monitoring mechanism 3 includes an image acquisition component, which is used to collect an image of the connection between the conductive member 21 and the lightning rod 6. Figure 1 As shown, the image acquisition component is also installed on the fixed platform 25. In this embodiment, the image acquisition device is a camera.

[0055] Furthermore, the remote monitoring mechanism 3 also includes an image display device arranged on the ground, and the image acquisition component transmits the acquired image back to the image display component on the ground, so that the staff can monitor the working condition of the connection device on the ground.

[0056] Furthermore, the connection device further comprises an outer cover 4 which is arranged outside the sleeve 1 and the connection mechanism 2. The outer cover 4 is provided to protect the sleeve and the connection mechanism and the remote monitoring mechanism installed on the sleeve.

[0057] Furthermore, in order to provide effective power support for the connection device, the connection mechanism 2 also includes a battery 5 for powering the motor 22 and the image acquisition device. In this embodiment, the battery is a 12V battery box.

[0058] like Figure 3 , 4 As shown, when the lightning rod detection connection device of this embodiment is used to connect and detect the lightning rod, the lightning rod detection connection device and the test line are carried on the unmanned aerial vehicle, and the test end of the test line is conductively connected to the brush of the lightning rod detection connection device motor, and the ground end is connected to the ground resistance tester; the ground control end controls the flight of the unmanned aerial vehicle, and the unmanned aerial vehicle carries the test line and the lightning rod detection connection device to fly to the top of the building, and the sleeve of the lightning rod detection connection device is sleeved and fixed on the lightning rod; the motor drives the conductive part of the lightning rod detection connection device to move so as to remove the insulating layer on the surface of the lightning rod, and then the conductive part forms a good conductive connection with the lightning rod; because the brush and the conductive part also form a conductive connection, the connection between the ground resistance tester and the lightning rod at the top of the building can be realized through the connection device, so as to perform an electrical path test.

[0059] Embodiment 2

[0060] Figure 3 , Figure 4 This is a lightning protection rod detection and connection system based on a drone in this embodiment, such as Figure 3 , 4 As shown, the connection system of this embodiment includes the lightning protection rod detection connection device 100 of the first embodiment, as well as a test line 300 and a drone 400;

[0061] The drone 400 is used to carry the test line 300 and the lightning protection rod detection connection device 100 to fly to the lightning protection rod 200, so that the sleeve 1 of the lightning protection rod detection connection device 100 is sleeved and fixed on the lightning protection rod 200;

[0062] The test end of the test line 300 is connected to the drone 400 and the test end is conductively connected to the brush 221 of the motor 22 of the lightning protection rod detection connection device 100, and the ground end of the test line 300 is used to connect to the ground resistance tester 500;

[0063] During connection, the sleeve 1 is sleeved and fixed on the lightning rod 200 by the drone 400, and the conductive member 21 of the lightning rod detection connection device 100 moves under the drive of the motor 22 to remove the insulating layer on the surface of the lightning rod 200, and the conductive member 21 is conductively connected to the lightning rod 200.

[0064] When the lightning rod detection connection system of this embodiment is used to connect and detect the lightning rod, the ground end of the test line is connected to the ground resistance tester, and the ground control end controls the flight of the drone. The drone carries the test line and the lightning rod detection connection device to the top of the building, and the sleeve of the lightning rod detection connection device is connected and fixed on the lightning rod; the motor drives the conductive part of the lightning rod detection connection device to move so as to remove the insulating layer on the surface of the lightning rod, and then the conductive part forms a good conductive connection with the lightning rod. Since the brush and the conductive part also form a conductive connection, the connection system can realize the connection between the ground resistance tester and the lightning rod at the top of the building, so as to perform an electrical path test.

[0065] Embodiment 3
