Infrared camera and unmanned aerial vehicle carrying out natural gas line patrolling based on infrared camera

Abstract

The invention relates to an infrared camera and an unmanned aerial vehicle carrying out natural gas line patrolling based on the infrared camera. The unmanned aerial vehicle comprises the infrared camera, a body, a vertical tail, a horizontal tail, ailerons, rotor wings, main wings, a compass and a GPS; a front pull motor is arranged at the front part of the body; the main wings are located on thetwo sides of the upper part of the body; the ailerons are correspondingly located on the outer sides of the rear edges of wingtips of the main wings; the rotor wings are located on the two sides of the body and the front side and the rear side of the main wings correspondingly; and the rotor wings are connected with the main wings through connecting rods correspondingly. When the unmanned aerialvehicle takes off, the rotor wings are unlocked first, the unmanned aerial vehicle vertically takes off and flies to a specified altitude, and then the main wings produce lifting force for flying; andwhen the unmanned aerial vehicle enters into a descending state, the unmanned aerial vehicle descends in a rotor wing mode. The measured natural gas content and recorded latitudes and longitudes, heights, and unmanned aerial vehicle attitude information by the scheme can be transmitted to a ground monitoring station in real time, so that the leakage situation of a natural gas line is observed inreal time conveniently.

Description

technical field [0001] The invention relates to the application field of an infrared camera, in particular to the field of an unmanned aerial vehicle for inspecting natural gas pipelines based on an infrared camera. Background technique [0002] Natural gas is closely related to the lives of residents. my country's natural gas pipelines have the characteristics of long total mileage, large span of construction years, frequent safety incidents and accidents, and the total mileage of pipelines shows a trend of rapid growth. Strengthening the safety patrol management of pipelines will make the situation more severe. The safety of pipelines for transporting natural gas is an important responsibility of society and enterprises. 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 us...

AI Technical Summary

Problems solved by technology

In the past, the traditional natural gas safety inspection mainly relied on the staff to use the hand-held telemeter to detect, the workload was heavy and the efficiency was low

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 real time

The current rotor UAVs have short flight time and short cruising distance, which cannot meet the application of UAVs in various fields. At the same time, the current rotor UAVs are basically equipped with natural gas content detection when inspecting natural gas pipelines. System and camera, the system is complex and expensive

[0003] At present, most of the natural gas pipeline inspection UAVs are six-rotor UAVs. Although the six-rotor UAVs can meet the requirements of various terrain inspections, their flight speeds are slow, the cruising distance is short, and they cannot independently match the flight height.

[0004] 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.
