[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0036] like Figure 1As shown, a gas detection drone device includes: a drone body 1, a plurality of rotors rotatably connected to the top of the drone body 1, a bracket connected to the bottom of the drone body 1, a gas detection module 2 connected to the top of the drone body 1, and a gas neutralization module 3 connected to the bottom of the drone body 1, wherein the gas detection module 2 is connected to the gas neutralization module 3;

[0037] The gas detection module 2 includes: a detection shell 21 connected to the top of the drone body 1, an airflow cavity 22 opened in the detection shell 21, a gas sensor 23 connected to the inner wall of the airflow cavity 22, a plurality of airflow plates 24 connected to the inner wall of the airflow cavity 22, a first pump 25 and a second pump 26 connected to the detection shell 21; the first pump 25 and the second pump 26 are symmetrically connected to the airflow cavity 22; the gas sensor 23 sends neutralization information; and the airflow cavity 22 is provided with an exhaust port 27.

[0038] like Figure 2 As shown, further, the exhaust port 27 is arranged at the top of the arc-shaped cavity.

[0039] Furthermore, a plurality of the air flow plates 24 are relatively connected to the inner wall of the air flow cavity 22 , and the angles formed between the plurality of the air flow plates 24 and the inner wall of the air flow cavity 22 are acute angles.

[0040] Specifically, the airflow plate 24 is made of a lightweight, strong and corrosion-resistant material, such as aluminum alloy or stainless steel, to ensure its durability and stability.

[0041] Specifically, the angle formed between the airflow plate 24 and the inner wall of the airflow chamber 22 is an acute angle (e.g., between 30° and 60°). This design helps to effectively block the airflow in the blocking mode, forcing the gas to change its flow direction during passage, thereby increasing the gas's residence time in the airflow chamber 22. In the guiding mode, the airflow plate 24 can smoothly guide the airflow, reducing resistance.

[0042] Furthermore, when the first pump 25 is turned on and the second pump 26 is turned off, several of the air flow plates 24 are used to block the flow; when the first pump 25 is turned off and the second pump 26 is turned on, several of the air flow plates 24 are used to guide the flow.

[0043] Specifically, when the first pump 25 is on and the second pump 26 is off, the airflow plate 24 is in a flow-blocking state. At this point, the angle and position of the airflow plate 24 restrict direct airflow, forcing the gas to pass slowly through the airflow chamber 22, thereby increasing the contact time and area between the gas and the gas sensor 23. This facilitates gas concentration detection.

[0044] When the first pump 25 is turned off and the second pump 26 is turned on, the airflow plate 24 is in a diversion state. The angle and position changes of the airflow plate 24 allow the airflow to pass through the airflow chamber 22 smoothly, reducing resistance, which is more convenient for rapid identification of gas in this case.

[0045] Furthermore, the gas sensor 23 is connected to the middle of the inner wall of the airflow cavity 22 .

[0046] Specifically, the gas sensor 23 is installed in the middle of the inner wall of the airflow chamber 22 to ensure that the gas has a relatively uniform flow rate and concentration distribution when flowing through this area. Such a location selection helps to improve the accuracy and reliability of detection.

[0047] Furthermore, the gas sensor 23 is an electrochemical gas sensor 23 .

[0048] Specifically, an electrochemical gas sensor 23 is used as the detection element. Electrochemical gas sensor 23 uses chemical reactions to generate electrical signals to detect gas concentrations. It has the characteristics of high sensitivity, fast response, and low power consumption. It is particularly suitable for detecting toxic and harmful gases such as H2S and NO2.

[0049] Furthermore, the airflow cavity 22 is an arc-shaped cavity.

[0050] Specifically, the airflow cavity 22 is designed as an arc-shaped cavity. This shape helps to guide the airflow to form a vortex motion and increase the residence time of the gas in the cavity.

[0051] like Figure 3 As shown, further, the neutralization module includes a water storage tank, a third pump connected to the water storage tank, a nozzle connected to the output end of the third pump, and a controller connected to the third pump; the controller is connected to the gas sensor 23; the controller receives neutralization information.

[0052] Specifically, the controller receives the neutralization information, and the controller controls the third pump to extract the liquid in the water storage tank for spraying.

[0053] Furthermore, the nozzle is an atomizing nozzle. Specifically, the nozzle is made of stainless steel, which has good corrosion resistance and stability.

[0054] More specifically, the nozzle is located directly below the drone body 1, which reduces the risk of the sprayed liquid covering the drone body 1 and causing damage to the drone body 1. At the same time, the atomizing nozzle makes the water mist effect better and improves the neutralization effect.

[0055] Furthermore, the water storage tank is filled with a neutralizer, and the neutralizer is NaOH.

[0056] When the utility model is used, after the drone is controlled to reach the designated position, the first pump 25 is turned on and the second pump 26 is turned off. The gas enters the airflow chamber 22, passes through the airflow plate 24 and reaches the position of the gas sensor 23. The gas concentration is detected by the gas sensor 23, and the gas then goes out through the exhaust port 27; the gas sensor 23 sends neutralization information to the controller, and the controller controls the third pump to extract the solution and release it.

[0057] Turn on the second pump 26 and turn off the first pump 25. The gas enters the airflow chamber 22, passes through the airflow plate 24 and reaches the gas sensor 23. The gas is detected by the gas sensor 23 and then goes out through the exhaust port 27. The gas sensor 23 sends neutralization information to the controller, and the controller controls the third pump to extract the solution and release it.

[0058] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
