A fixed-wing UAV based on vertical take-off and landing and its natural gas pipeline inspection system and method

Abstract

A fixed-wing unmanned aerial vehicle based on vertical take-off and landing and its natural gas pipeline inspection system. The method includes a fuselage, a vertical tail, a horizontal tail, an aileron, a rotor, and a main wing. On both sides of the upper body, the ailerons are respectively located outside the rear edge of the main wing tip, and the rotors are respectively located on both sides of the fuselage and the front and rear sides of the main wing, and are respectively connected to the main wing through connecting rods; when the drone takes off, first unlock the rotor , the UAV takes off vertically. After flying to the specified height, the front pull motor starts, and the rotor gradually reduces the throttle. When the UAV can fly only under the action of the front pull motor, the rotor stops completely, and the UAV starts to fly Under the action of the front pulling motor, the main wing generates lift to fly. When the UAV enters the landing state, the UAV lands in the rotor mode. An unmanned aerial vehicle, a natural gas content detection system, a camera, and a ground monitoring station constitute a natural gas pipeline inspection system and a method for performing natural gas pipeline inspection through the system.

Description

technical field [0001] The invention relates to the application field of unmanned aerial vehicles, in particular to the field of natural gas pipeline inspection of unmanned aerial vehicles. Background technique [0002] The current rotor UAVs have short flight time and short cruising distance, which cannot meet the application of UAVs in various fields. [0003] Natural gas is closely related to the lives of residents, and it is an important responsibility of society and enterprises to ensure the safety of pipelines for transporting natural gas. In the past, traditional natural gas safety inspections mainly relied on staff using hand-held telemeters for inspections, which resulted in heavy workload and low efficiency. In addition, hand-held telemeters are limited by ground terrain and cannot be used in some places that are difficult for humans to reach. The alternative, helicopters, has high risks, high costs, cumbersome operating procedures, and is not easy to monitor in r...

AI Technical Summary

Problems solved by technology

[0007] Due to the long mileage of natural gas pipelines and the complex terrain across regions, the general line inspection method has high manpower and material costs, single data, poor timeliness, and heavy processing workload, which cannot meet the needs of current pipeline inspections.

Therefore, it is necessary to use a simple structure, reasonable design, easy to use and operate, and long cruising distance to make up for the defects and deficiencies of the existing inspection methods such as large manpower and material resources, difficult inspection work, and poor inspection effects.
