[0002] Inspection drones are devices that use high-resolution cameras and other sensors onboard drones to conduct aerial inspections and detections of specific areas. Inspection drones have demonstrated their unique application value in multiple industries. In the power industry, they can be used to inspect high-voltage lines and substations to detect damage or failures in a timely manner, avoid power outages and equipment damage, and monitor long-distance pipelines and facilities in the oil and gas industry to detect leaks, corrosion and other potential problems. Infrastructure inspections can inspect high-rise buildings, bridges, tunnels and other infrastructure to assess structural integrity and construction progress. In the agricultural field, they can monitor crop growth, assess irrigation needs, and detect pests and diseases early. In nature reserve monitoring, they can track wild animals, assess ecological and environmental changes, and prevent forest fires. In traffic management, they can monitor road conditions, analyze traffic flow, and respond quickly to accident sites. In search and rescue, they can provide real-time images of disaster-stricken areas to assist rescue teams in natural disasters or emergencies.

[0037] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0038] like Figure 1-10 As shown, the inspection drone anti-fall protection frame includes:

[0039] The main body 100 is fixedly connected to the cantilever 200 on all sides, and a wheel shell 201 is fixedly installed on one end of the cantilever 200 away from the main body 100. An anti-collision protection mechanism is provided on the outer edge of the cantilever 200, and the two cantilevers 200 located on the same side of the main body 100 are respectively fixedly connected to the two ends of the cover plate 300, and an ejection mechanism is provided inside the cover plate 300, and a closed protection mechanism adapted to the ejection mechanism is slidably connected inside the cover plate 300;

[0040] The shell 400 and the protective shell 500, the shell 400 is fixedly mounted to the top of the cover plate 300, the shell 400 is connected to the buffer protection mechanism, the protective shell 500 is rotatably connected to the bottom of the main body 100, the protective shell 500 corresponds to one side of the surveillance camera 103 below the main body 100, the other side of the protective shell 500 is provided with a locking mechanism installed on the main body 100, and a limiting mechanism is provided on one side of the connection between the protective shell 500 and the main body 100.

[0041] In the present technical solution, the bottom of the main body 100 is rotatably connected with a bracket 101, the top of the bracket 101 is embedded in the notch opened in the main body 100, and the notches on both sides of the bracket 101 are fixedly connected with pressure sensors 102, and the pressure sensors 102 are electrically connected to the locking mechanism. The bracket 101 is used to support the main body 100, and when supporting, the bracket 101 contacts the pressure sensor 102. When landing or landing quickly while tilting, the bracket 101 is subjected to a large pressure. At this time, the pressure value detected by the pressure sensor 102 changes. At this time, the electrical signal of the pressure sensor 102 is amplified and transmitted to the controller of the drone, thereby controlling the controller of the electromagnetic coil 502 to energize it. At this time, the electromagnetic A magnetic field is formed inside the coil 502 and pulls the armature 503 to reset. The armature 503 drives the limit block 504 to separate from the protrusion 501. At this time, the elasticity of the spring 505 pushes the protective shell 500 to rotate rapidly.

Both ends of each of the first gas generators 208 are connected to the interior of the first airbag 207. A groove 206 is provided on the outer surface of the cantilever 200, and the first airbag 207 is embedded in the groove 206. Both sides of the first airbag 207 are folded and distributed inside the groove 206. When tipping occurs, the first gas generator 208 is activated to generate a large amount of gas and enter the first airbag 207. The first airbag 207 bulges and moves out from the inside of the groove 206, thereby achieving buffering protection around the cantilever 200, avoiding damage to the cantilever 200 when falling, and improving safety protection performance.
