Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a drone device for gas detection. Background Art

[0002] As the environment deteriorates, environmental monitoring often requires simultaneous monitoring of various gases in the air at high altitudes. Gas detection is a method that uses various sensors and technologies to detect the gas components and concentrations in the air. It is widely used in various fields such as industrial safety, environmental monitoring, and medical diagnosis. When testing high-altitude air, gas detection devices are usually installed on drones, which carry the devices to high altitudes and collect gases. Therefore, a drone-based gas detection device is needed.

[0003] A Chinese patent application, with the authorization publication number CN216411201U, discloses a gas detection device for drones, comprising a drone and a gas detection box. The gas detection box is detachably mounted on the bottom of the drone. The gas detection box comprises a box body, a gas detection module, a circuit board, and a quick-release assembly. The gas detection module is electrically connected to and mounted on the circuit board, which is mounted within the box body. The quick-release assembly is mounted on the top of the box body, and the box body is detachably connected to the drone via the quick-release assembly. The box body is provided with ventilation holes on corresponding sides, and an intake fan and an exhaust fan are provided inside the box body. The intake fan and exhaust fan are respectively arranged at the ventilation holes on both sides of the box body and connected to the circuit board. This utility model adopts open detection, with ventilation holes on both sides of the gas box, dual fans for air intake and exhaust, and sensors arranged in two layers, maximizing contact with the outside air, increasing air intake and exhaust volume, and achieving more accurate measurements.

[0004] Although the gas detection drone mentioned above adopts open detection, with ventilation holes on both sides of the gas box, dual fans are used for air intake and exhaust inside, and the sensors are arranged in two layers, which maximizes contact with the outside air, has a large air intake and exhaust volume, and more accurate measurements, but generally there is a lack of classification chambers on drones. In the process of collecting gas, it is difficult to classify and collect gas in multiple areas, which easily leads to the singleness of experimental data and inaccurate detection. For this reason, we propose a drone device for gas detection. Utility Model Content
