[0002] Dangerous chemicals refer to highly toxic chemicals and other chemicals with properties such as toxicity, corrosion, explosion, combustion, and combustion support, which are harmful to the human body, facilities, and environment. Dangerous chemicals should be stored separately by category, warehouse, piece, and shelf. Their storage warehouses should meet the standards, strictly control the temperature, and lightning protection facilities should be installed, etc. In the event of a leakage during the storage or transportation of dangerous chemicals, in order to avoid the impact of chemicals on the external environment and the health of nearby personnel, an unmanned aerial vehicle is used to check the on-site situation.

[0003] During the use of an unmanned aerial vehicle, components such as cameras and smoke collectors on the vehicle are required to view and collect data on the on-site environment, so as to facilitate the judgment of the on-site situation. However, during the use of existing unmanned aerial vehicles, the vehicle only analyzes the on-site situation, resulting in low practicability of the device, and the vehicle cannot effectively protect the monitoring components during use. For this reason, an unmanned aerial vehicle applied to three-dimensional prevention and control of dangerous chemical accidents is proposed to solve the above problems. Content of the Utility Model

Specific implementation manners

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a non - manned aircraft for three - dimensional prevention and control of hazardous chemical accidents, including a fuselage 1. A plurality of groups of support legs 2 are respectively arranged on the outer side of the fuselage 1, and propellers 3 are respectively arranged on the upper end surfaces of the support legs 2. A camera 7 is arranged on the front of the fuselage 1, and a smoke collector 8 is arranged below the camera 7. A first servo motor 4 is arranged on the fuselage 1 above the camera 7, and one end of the output shaft of the first servo motor 4 is connected to a rotating shaft 5 through a coupling. A protective cover 6 is arranged on the outer wall of the rotating shaft 5.

[0020] Furthermore, under the action of the first servo motor 4, the protective cover 6 forms a rotating structure with the fuselage 1 through the rotating shaft 5. Thus, when the aircraft is flying normally, the camera 7 and its related monitoring components can be protected by the protective cover 6, and under the action of the first servo motor 4, the protective cover 6 is prevented from affecting the monitoring process of the accident scene by this device.

[0021] Fixing plates 9 are respectively arranged on both sides of the lower end surface of the fuselage 1, and support plates 11 are respectively arranged on the lower end surfaces of the fixing plates 9. Bolts 10 are respectively screwed on the fixing plates 9, and the other ends of the bolts 10 are screwed into the connecting rod. The other ends of the connecting rods are respectively connected to the water storage tank 12 and the outer shell 19.

[0022] Further, the water storage tank 12 and the outer shell 19 respectively form a spiral locking structure with the fixing plate 9 through bolts 10 and connecting rods, so that it is convenient to spiral mount components such as the water storage tank 12 and the exhaust fan on the aircraft through the bolts 10, thereby increasing the practicality of the aircraft.

[0023] A water pump 13 is provided on the upper end surface of the water storage tank 12, and multiple groups of water inlet pipes 14 are provided on the water pump 13. The other ends of the water inlet pipes 14 are respectively connected to the spray arms 15, and nozzles 16 are provided below the spray arms 15. Fixed blocks 17 are respectively provided on both sides of the spray arms 15 on the support legs 2, and elastic limit blocks 18 are respectively provided on the outer walls on both sides of the spray arms 15. Limit holes are correspondingly opened on both sides of the fixed blocks 17, and the elastic limit blocks 18 are inserted into the limit holes.

[0024] Further, the spray arm 15 forms an elastic snap - limit structure with the fixed block 17 through the elastic limit block 18 inserted into the limit hole, and the nozzle 16 forms a communication structure with the water storage tank 12 through the water inlet pipe 14 and the spray arm 15 under the action of the water pump 13. Thus, when the aircraft is working, the nozzles 16 can prevent high - temperature situations such as fires from affecting the relevant components of the aircraft, and at the same time, the nozzles 16 spray the accident scene to reduce risks.

[0025] A second servo motor 20 is provided at the rear of the outer shell 19, and an output shaft is provided on the second servo motor 20. Multiple groups of fan blades 21 are provided on the outer wall of the output shaft.

[0026] Further, the fan blades 21 form a rotating structure inside the outer shell 19 through the output shaft under the action of the second servo motor 20. Thus, when a gas substance leaks, the rotating fan blades 21 can increase the air fluidity in the vicinity, thereby preventing the concentration of dangerous gases from being too high and increasing the danger.

[0027] Working principle: When using the unmanned aircraft applied to the three-dimensional prevention and control of hazardous chemical accidents, first, the corresponding treatment device can be selected according to the situation of the on-site accident. If it is necessary to monitor the scene of a flammable chemical accident, the water storage tank 12 can be placed on the support plate 11 and screwed on through the bolt 10. At the same time, the spray arm 15 can be snap-fitted on the support leg 2 through the elastic limit block 18. When the aircraft monitors the accident scene, the water pump 13 can be started, so that the spray head 16 is driven to work through the water inlet pipe 14 and the spray arm 15, so as to spray the scene through the spray head 16 to reduce the risk and avoid damage to the aircraft caused by the fire; if it is necessary to deal with a gas chemical accident, the shell 19 and its related components can be installed on the fixed plate 9 through the bolt 10, and after on-site monitoring, the aircraft can be moved to a suitable position, so that the fan blade 21 is driven to rotate under the action of the second servo motor 20, so as to increase the fluidity of the air near the gas chemical through the rotating fan blade 21; during the monitoring of the on-site situation by the aircraft components, the first servo motor 4 can be used to drive the rotating shaft 5 to rotate, so as to protect the relevant monitoring components through the protective cover 6, thereby ensuring the service life of the aircraft. This is the use process of the unmanned aircraft applied to the three-dimensional prevention and control of hazardous chemical accidents.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
