Description

Technical Field

[0001] The present invention relates to the field of aircraft, and in particular to a monitoring drone for social security. Background Art

[0002] An unmanned aircraft is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an on-board computer. In the civil field, drones + industry applications are the real rigid demand for drones; their current applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] After searching, the Chinese patent application with application publication number CN209051593U discloses a social security monitoring drone, which belongs to the field of security monitoring. A social security monitoring drone, the existing drones have all their cameras exposed to the outside whether in use or not, which will cause irreversible damage to the camera in the long run. The camera is hidden inside the protective shell when the device is designed, and the camera is placed outside the protective shell through the hydraulic lifting rod when in use, which can effectively protect the camera, and there are multiple usage states. In a place with good light, you only need to start the hydraulic lifting rod to lift the high-precision camera out of the protective shell. When the light is not good, continue to start the hydraulic lifting rod to lift the auxiliary night imaging camera out of the protective shell, which can more effectively assist monitoring.
