Description

Unmanned aerial vehicle type industrial hazardous gas leakage detection system capable of freely adjusting angle

Technical Field

The invention relates to the technical field of gas detection, in particular to an unmanned aerial vehicle type industrial hazard gas leakage detection system with an angle capable of being freely adjusted.

Background

Existing gas detection devices can be classified into a contact combustion type, an electrochemical type, and an infrared optical type according to a detection principle. The installation form can be divided into: the traditional electrochemical point-type combustible gas detector utilizes a gas sensitive element to carry out chemical reaction with combustible gas nearby the gas sensitive element, so that the detection of the combustible gas is realized by the variable quantity of the change detection of certain properties of the detection element. However, the gas leakage such as H2S and the like occurs in the monitoring area, and the gas leakage is easy to cause the defects of poisoning and the like; the contact combustion type detector has the defects of short service life, rapid sensitivity reduction after being easily polluted and the like in application, and an infrared optical type combustible gas detector generally needs a detection cavity, an induced draft fan and an infrared emission and receiving component. The existing infrared optical type combustible gas detector is not an open light path, and still belongs to contact type measurement.

By adopting the thermal imaging gas leak detector, after an accident occurs in a gas processing operation factory, gas leakage detection is carried out on the accident site, so that the detection result can be rapidly displayed to an observer in a manner acceptable by human eyes in real time, and the diffusion track of combustible gas or toxic gas can be intuitively judged.

Refer to chinese patent publication No. CN205504489U for a unmanned aerial vehicle pipeline inspection device carrying a laser methane gas leakage detector, and connect through wireless communication. The utility model discloses combine together modern unmanned aerial vehicle technique, laser methane gas leakage detection technique, digital imaging system, communication teletransmission technique and GPS technique, realized patrolling and examining hourglass and real-time video passback function to gas pipeline, quick location, improved gas patrol efficiency, it is more accurate to leak the location to the gas.

Refer to chinese patent publication CN 211927677U's an unmanned aerial vehicle carries laser methane and leaks patrol appearance, through setting up support and go-between with laser detector carry on unmanned aerial vehicle, through setting up the triaxial and increasing steady cloud platform, set up adjustment frame adjustment laser detector's detection angle, make unmanned aerial vehicle when rocking, the pointing of equipment is on the detection target all the time, and the detected value is stable, and the image is also stable clear.

Refer to chinese patent publication No. CN111947037A and leak detection system based on unmanned aerial vehicle natural gas line, through setting up the reposition of redundant personnel cover structure, solved and carry out the gas detection time measuring using unmanned aerial vehicle, its screw can produce the air near decurrent air current blowing detection zone when unmanned aerial vehicle suspends and then lead to the combustible gas line to leak the technical defect of the condition of revealing that detection system can not the accurate detection pipeline.

A comprehensive analysis of the above referenced patents can yield the following drawbacks:

1) the existing thermal imaging detection equipment carried on the unmanned aerial vehicle can only singly realize thermal imaging detection in one direction, because the scene situation of dangerous gas leakage accidents is complex, a plurality of leakage points or a plurality of obstacles can often appear to block the detection position, therefore, in order to detect the accident leakage points, the detection direction of thermal imaging needs to be adjusted, most of the existing methods for adjusting the detection direction directly adjust the posture of the unmanned aerial vehicle to realize detection on the accident points in different directions, for example, refer to an unmanned aerial vehicle pipeline inspection device carrying a laser methane gas leakage detector of patent CN205504489U, an unmanned aerial vehicle-carried laser methane leakage inspection device of CN211927677U and a natural gas pipeline leakage detection system based on the unmanned aerial vehicle of CN111947037A, no innovation is carried out on the angle adjusting part of the unmanned aerial vehicle detection equipment, and only the detection direction can be adjusted by adjusting the posture of the unmanned aerial vehicle, the unmanned aerial vehicle gesture of adjustment is loaded down with trivial details relatively, need the testing personnel to observe the current gesture of unmanned aerial vehicle earlier with the telescope, watch the formation of image again and adjust, the adjustment is loaded down with trivial details, the limitation is big, and use inflexible, can not realize through direct adjustment imaging device direction, realize detecting the condition of different accident points, can't reach not only fast but also convenient observe the purpose that detects to dangerous gas leakage accident point, thereby bring very big inconvenience for testing personnel's detection achievement.

2) The stable anti-shake effect of current thermal imaging check out test set is relatively poor, refer to patent CN211927677U for example and fail to design a simple anti-shake structure for an unmanned aerial vehicle carries laser methane and leaks the appearance of patrolling and examining, combine anti-shake structure and angle adjustment mechanism, realize carrying out the multi-functional use to the thermal imaging check out test set on the unmanned aerial vehicle, but through adopting the great triaxial of a volume to increase steady cloud platform, solve the shake suppression problem of imaging check out test set when detecting, it is practical obviously lower.

3) Current thermal imaging check out test set is comparatively loaded down with trivial details when being connected the installation with unmanned aerial vehicle, and the dismouting is inconvenient, and inconvenient people clears up the thermal imaging check out test set and maintains, can not realize not only quick but also convenient getting off thermal imaging check out test set and unmanned aerial vehicle separation to inconvenient people's use.
