Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle detection, and in particular to an amusement facility detection system based on unmanned aerial vehicles. Background Art

[0002] At present, drone systems have been used to a certain extent in power line inspection, bridge quality inspection, wind turbine blade damage inspection, pipeline inspection, and highway maintenance inspection. In recent years, major domestic special inspection agencies have gradually carried out research on the introduction of drones into large special equipment such as cranes and petrochemical enterprises, including emergency rescue, accident site investigation, inspection and testing, etc. Drones can free inspection personnel from high-altitude, high-temperature, toxic and harmful high-risk working environments, and achieve safer and more efficient inspections.

[0003] For large-scale amusement facilities, during long-term use, due to the influence of factors such as alternating loads, friction and wear, and welding defects, defects such as weld cracking, wear of key components, and structural deformation will occur. Long-term outdoor parking will cause paint peeling, rust, and material aging. However, due to many factors such as the scale of the equipment, the high location of key components, and certain dangers in the inspection environment, it is difficult for inspectors to inspect and test key components that are prone to wear and corrosion in some difficult-to-reach areas of this type of equipment. The existence of uninspected blind spots will leave potential safety hazards for the operation of the equipment. Due to the high structural complexity of amusement facilities, as well as the large size, large footprint, and excessive height, it is easy to make omissions during manual inspections, and safety problems of facilities on the ground or without the assistance of lifting tools cannot be discovered in time.
