Technical Field
[0001] This utility model relates to the field of lightning protection detection technology, and in particular to a lightning protection detection device based on a drone. Background Technology
[0002] Due to aesthetic and safety requirements, modern buildings no longer have access points on rooftops, making it impossible for technicians to inspect the electrical integrity and corrosion of lightning arresters (lightning strips) on-site. Furthermore, traditional manual inspection methods are risky and time-consuming. A search revealed a patent document with authorization announcement number CN220584312U, which discloses a drone-based lightning protection detection device. This device includes a drone carrier, a safety release device, and pneumatic components. The drone carrier comprises a drone and a fixing clamp positioned beneath the drone. The safety release device employs… The device is installed in the middle of the fixed fixture using a dual-point fixing method. The pneumatic assembly includes a pneumatic clamp, a pneumatic rust removal device, a connecting rod, a mobile air pump, and a grounding resistance tester. The starting point of the connecting rod is connected to the safety release device. The pneumatic rust removal device is installed at a first preset distance from the starting point of the connecting rod. The pneumatic clamp is installed at the ending point of the connecting rod. The output end of the mobile air pump is connected to the input end of the pneumatic rust removal device and the input end of the pneumatic clamp. The grounding resistance tester is connected to the second input end of the pneumatic clamp. The connection method between the UAV and the pneumatic assembly, as well as the structure of the pneumatic assembly, are improved to enhance the stability of the UAV lightning protection detection device, thereby improving detection accuracy and efficiency.
[0003] However, the above design still has shortcomings. The design uses pneumatic devices (pneumatic clamps, pneumatic rust removal devices), which have three problems: First, the power source is unstable. The power source (compressed air) is easily affected by factors such as air pressure changes and air supply, thus affecting the stability and reliability of the clamps and rust removal devices. Second, the precise control and positioning capabilities are poor. The fixed-length connecting rod and the fixed-angle clamp are prone to deviation or instability when clamping and releasing the lightning protection device, affecting the execution effect of the inspection task. Third, the response speed and work efficiency are low. The gas compression and release process requires a certain amount of time, resulting in a relatively slow response speed of the pneumatic clamps and pneumatic rust removal devices, thereby reducing the work efficiency of UAV lightning protection inspection. Utility Model Content
[0004] Purpose of the utility model: The purpose of this utility model is to address the shortcomings of existing technologies, such as poor power source stability, poor precise control and positioning capabilities, and low response speed and working efficiency.

The starting point of the electric telescopic linkage is connected to the lower end of the power supply box, and the ending point is connected to one end of the electric universal joint, the other end of which is connected to the electric grinding fixture. The grounding resistance tester is connected to the electric grinding fixture via a test connection cable.
[0006] Furthermore, the electric grinding fixture includes a grinder, jaws, a grinder motor, and a jaw motor. The grinder motor controls the rotation of the grinder, and the jaw motor controls the opening and closing of the jaws.

Detailed Implementation
[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0018] Reference Figure 1 This is a schematic diagram of the structural relationship of a UAV lightning protection testing device according to an embodiment of the present invention. The device includes a UAV carrier, a power supply box, and an electric component. The UAV carrier includes a UAV and a mounting bracket, which is positioned below the UAV. The power supply box includes a battery, a remote control switch, and a remote wireless remote controller, which are mounted on the mounting bracket using a sliding groove fixing method, providing power to the electric grinding fixture, the electric telescopic linkage, and the electric universal joint. The electric component includes the electric grinding fixture, the electric telescopic linkage, the electric universal joint, and a grounding resistance tester. The starting point of the electric telescopic linkage is connected to the lower end of the power supply box, and the ending point of the electric telescopic linkage is connected to one end of the electric universal joint. The other end of the electric universal joint is connected to the electric grinding fixture. The power output line in the power supply box is located inside the electric telescopic linkage, and the grounding resistance tester is connected to the test line end of the electric grinding fixture.
[0019] During lightning protection testing, the inspectors hover the drone in a suitable position in the air and use the drone's camera to check if the lightning arrester is rusted. Once rust is confirmed, the drone guides the lightning arrester into the jaws of an electric grinder-clamp. After confirming the lightning arrester is in the clamping position via the drone's camera, the power switch of the electric grinder-clamp is remotely turned on, and the jaws close reliably clamp the lightning arrester. The power switch of the grinder is then remotely turned on, and the grinder is used to grind the tested area. After grinding, the power to the grinder is remotely disconnected, and the grinder stops working. A ground resistance tester is then used to begin testing. After the ground resistance test is completed, the power switch of the electric grinder-clamp is remotely turned off, the electric grinder-clamp opens its jaws, and the drone is returned to its original position.
[0020] like Figure 2 As shown, Figure 2 This is a schematic diagram of the electric grinder-clamp structure. Because the electric grinder-clamp is a metal component, it ensures a reliable electrical connection between the clamp's test leads and the lightning arrester. When the electric grinder-clamp's jaws hold the lightning arrester, completing the electrical connection, a grounding resistance tester is activated on the ground to measure the lightning arrester's grounding resistance. After the measurement is complete, ground personnel remotely disconnect the power to the electric grinder-clamp's jaws, the clamps open, and the drone carries it back to the ground.
[0021] like Figure 3 As shown, Figure 3 The diagram shows the structure of the power supply box. The lithium battery pack supplies power to the grinder motor, jaw motor, electric telescopic linkage, and electric universal joint of the electric grinder-clamp via four sets of remote control switches. The status of the four sets of switches can be remotely controlled within a distance of 1000m via a wireless remote control.
[0022] The electric universal joint can control the electric grinding fixture to rotate 360 degrees in the horizontal direction. When the power is on, the joint starts to rotate and stops rotating when the power is off.
[0023] The electric grinder clamp is powered by two 12V DC power supplies, one for the grinder motor and the other for the clamp jaw motor. When the grinder circuit is powered, the grinder operates; when the power is disconnected, it stops operating. When the clamp jaw circuit is powered, the clamp is in a closed clamping state; when the power is disconnected, the clamp jaw is in an open state with a clamping force greater than 220N.
