Description

Technical Field

[0001] The invention relates to the technical field of gas detection, and in particular to a drone-type industrial hazardous gas leakage detection system with freely adjustable angles. Background Art

[0002] Existing gas detection devices can be divided into contact combustion type, electrochemical type, and infrared optical type according to the detection principle. According to the installation form, they can be divided into: point-type combustible gas detectors, independent combustible gas detectors, and portable combustible gas detectors. Traditional electrochemical point-type combustible gas detectors use gas-sensitive elements to react chemically with nearby combustible gases, causing certain properties of the detection elements to change and detecting this change to achieve the detection of combustible gases. However, it has the disadvantages of being easily poisoned when H2S and other gases leak in the monitoring area; the contact combustion type detector has the disadvantages of short life and a sharp drop in sensitivity after being easily contaminated in application. Infrared optical combustible gas detectors generally require a detection cavity, an induced draft fan, and infrared emitting and receiving components. The detector has high detection sensitivity, a variety of types, and reliable performance. Since the existing infrared optical combustible gas detectors are not open optical paths, they still belong to contact measurement.

[0003] By using a thermal imaging gas leak detector to detect gas leaks at the accident site after an accident occurs in a gas processing plant, the detection results can be displayed to the observer quickly and in real time in a way that is acceptable to the human eye, and the diffusion trajectory of combustible or toxic gases can be intuitively determined.

[0004] Referring to the Chinese patent publication number CN205504489U, a drone pipeline inspection device equipped with a laser methane gas leak detector is connected via wireless communication. The utility model combines modern drone technology, laser methane gas leak detection technology, digital imaging system, communication remote transmission technology, and GPS technology to realize the functions of gas pipeline inspection, rapid positioning and leak detection, and real-time video feedback, thereby improving the efficiency of gas inspection and locating gas leaks more accurately.

[0005] Referring to a UAV-mounted laser methane leak inspection instrument with Chinese patent publication number CN211927677U, the laser detector is mounted on the UAV by setting a bracket and a connecting ring, and the detection angle of the laser detector is adjusted by setting a three-axis stabilization gimbal and an adjustment frame, so that when the UAV shakes, the device is always pointed at the detection target, the detection value is stable, and the image is stable and clear.

[0006] Referring to a natural gas pipeline leak detection system based on a drone with Chinese patent publication number CN111947037A, a diversion hood structure is set to solve the technical defect that when using a drone for gas detection, the propeller of the drone will generate a downward airflow to blow away the air near the detection area when the drone is hovering, thereby causing the combustible gas pipeline leak detection system to be unable to accurately detect the leakage of the pipeline.

[0007] Comprehensive analysis of the above reference patents shows the following defects:

[0008] 1) The thermal imaging detection equipment carried by the existing drones can only realize thermal imaging detection in one direction. Since the scene of dangerous gas leakage accidents is relatively complicated, there are often multiple leakage points or many obstacles blocking the detection position. Therefore, in order to facilitate the detection of accident leakage points, it is necessary to adjust the detection direction of thermal imaging. Most of the existing methods for adjusting the detection direction are to directly adjust the posture of the drone to realize the detection of accident points in different directions. For example, the reference patent CN205504489U is a drone pipeline inspection device equipped with a laser methane gas leak detector, and the reference patent CN211927677U is a drone-mounted laser methane leak inspection device. The detector and CN111947037A, a natural gas pipeline leakage detection system based on a drone, have not made any innovations in the angle adjustment part of the drone-mounted detection equipment. The detection direction can only be adjusted by adjusting the attitude of the drone. Adjusting the attitude of the drone is relatively cumbersome. The detection personnel need to use a telescope to first observe the existing attitude of the drone, and then watch the imaging image to make adjustments. The adjustment is cumbersome, has great limitations, and is inflexible to use. It is impossible to detect the conditions of different accident points by directly adjusting the direction of the imaging equipment, and it is impossible to achieve the purpose of quickly and conveniently observing and detecting dangerous gas leakage accident points, which brings great inconvenience to the detection work of the detection personnel.

[0009] 2) The existing thermal imaging detection equipment has poor stabilization and anti-shake effects. For example, the reference patent CN211927677U, a UAV-mounted laser methane leak inspection instrument, fails to design a simple anti-shake structure to combine the anti-shake structure with the angle adjustment mechanism to achieve multifunctional use of the thermal imaging detection equipment on the UAV. Instead, it adopts a larger three-axis stabilization gimbal to solve the problem of shaking suppression of the imaging detection equipment during detection, which is obviously less practical.

[0010] 3) The existing thermal imaging detection equipment is complicated to connect and install with the drone, and it is inconvenient to disassemble and assemble. It is not convenient for people to clean and maintain the thermal imaging detection equipment. It is not possible to separate the thermal imaging detection equipment from the drone quickly and conveniently, which is inconvenient for people to use. Summary of the invention

[0054] Before use, first pull out the T-shaped connecting rod 1044, insert the thermal imaging detector body 11 to be used into the connecting groove 1043, and then loosen the T-shaped connecting rod 1044. The T-shaped connecting rod 1044 will be inserted into the limiting groove 1049 under the action of the reset spring 1046.

[0057] Vertical rotation adjustment: The staff can operate the remote control to send the vertical rotation angle value to the drone body 1, and the central processor 123 controls the electromagnet 1074 corresponding to the threshold vertical angle to start to be powered on, generate magnetism, repel the magnet 1075 outward, and make the T-shaped limit clamp 1073 of the corresponding angle extend and lock, and then the central processor 123 controls the microprocessor 16 to start working, and the microprocessor 16 controls the first air pump 17 and the electromagnetic valve in the pipe connecting the first air pump 17 and the second rotating cylinder 103 to start working, and the second rotating cylinder 103 drives the thermal imaging detector body 11 through the fixed block 1041 It rotates in the vertical direction, and the limit tooth 105 will rotate at this time. When the limit tooth 105 rotates to squeeze and contact with the T-shaped limit clamp 1073 that is extended and locked at this time, the microprocessor 16 controls the first air pump 17 to keep the second rotating cylinder 103 under pressure, thereby locking the thermal imaging detector body 11 in the vertical direction at this time, thereby completing the vertical adjustment of the thermal imaging detector body 11. At the same time, the second angle sensor matrix 108 can detect the rotation angle of the active end of the second rotating cylinder 103, and feed it back to the central processor 123, so that the staff can obtain the horizontal rotation angle in real time.

[0058] After the detection is completed, the staff directly operates the remote control to make the first air pump 17 control the second rotary cylinder 103 to rotate in the opposite direction to the initial position, and the second air pump 122 controls the first rotary cylinder 8 to rotate in the opposite direction to the initial position, thereby realizing the reset adjustment of the equipment.
