Detailed Implementation

[0027] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a chemical reconnaissance device based on a drone includes a remote controller (not shown) and a drone 3 equipped with a toxic gas detection sensor 1 and a thermal imaging reconnaissance device 2. The bottom of the drone 3 is equipped with a nuclear, biological, and chemical liquid collection device 100 and a nuclear, biological, and chemical soil collection device 200. The nuclear, biological, and chemical soil collection device 200 includes a rotating component and two sampling claws 4. The rotating component can drive the two sampling claws 4 to rotate relative to or in opposite directions for grabbing or releasing soil samples. The lower end of the collection hose 5 of the nuclear, biological, and chemical liquid collection device 100 can be lowered into a body of water for collecting water samples. The drone 3, the toxic gas detection sensor 1, the thermal imaging reconnaissance device 2, the nuclear, biological, and chemical liquid collection device 100, and the nuclear, biological, and chemical soil collection device 200 are all wirelessly connected to the remote controller.

[0029] During installation, the toxic gas detection sensor 1 and the thermal imaging reconnaissance device 2 are positioned at the edge of the drone 3. The nuclear, biological, and chemical liquid collection device and the nuclear, biological, and chemical soil collection device are both mounted side-by-side on the mounting frame 6 at the bottom of the drone. The bottom of the drone 3 is equipped with a clamping component 7 for securing the two extended sampling claws 4. The clamping component can be secured using either electromagnetic adsorption or mechanical claws, allowing the two sampling claws to be fixed in place during drone flight to prevent scratches.

[0030] As a preferred structure, such as Figure 2As shown, the rotating component includes a first motor 8, a driving gear 9, and a driven gear 10 meshing with it. The output shaft of the first motor 8 is coaxially fixed with the driving gear 9. The axles of the driving gear 9 and the driven gear 10 are respectively fixedly connected to the roots of the two sampling claws 4. The sampling claw 4 includes a telescopic arm and a bucket 11 at its end. The first motor is an asynchronous motor, started by a remote control. The meshing driving and driven gears drive the two sampling claws to rotate simultaneously relative to or opposite to each other. Relative motion enables the two sampling claws to grip and collect samples, while opposite motion allows the gripped soil samples to be released and unloaded.

[0031] In the specific design, the roots of the two buckets 11 can be abutted by elastic buffer pads 12 to avoid rigid collisions during sample grabbing; the free ends of the buckets are equipped with serrations 13, and the serrations 13 at the ends of the two buckets 11 can interlock; at the same time, both sides of the buckets 13 are equipped with elastic guards (not shown in the figure). The guards can be made of rubber material, and the interlocking serrations at the ends of the two buckets can ensure that the sample is retained inside the bucket, minimizing the leakage of soil samples from the bucket edges during flight.

[0032] In specific embodiments of this utility model, such as Figure 4 , 6 As shown, the nuclear, biological, and chemical liquid collection device includes a collection tube retraction component, a water pump 14, and a water collection tank 15. The collection tube retraction component drives the collection hose 5 to descend and ascend. A tubular filter screen 16 is provided at the lower inlet of the collection hose 5 to prevent sediment from clogging it. The lower end of the filter screen 16 is sealed, and a counterweight 17 is placed at the bottom of the filter screen 16 to ensure the collection hose 5 smoothly enters the water. The inlet of the water pump 14 is connected to the outlet of the collection hose 5, and the outlet of the water pump 14 is connected to the water collection tank 15. The bottom of the water collection tank 15 has a drain outlet 18 to facilitate the discharge of water samples from the tank. The top of the water collection tank 15 has a pressure relief valve 19 to prevent damage caused by excessive pressure.

[0033] In specific design, such as Figure 4 As shown, the collection tube winding and unwinding component includes a second motor 20 and a reel 21 for winding the collection hose 5. The output shaft of the second motor 20 is coaxially fixed with the reel 21. Both ends of the reel 21 are provided with baffles 22. The reel 21 is rotatably engaged with the baffles 22 through bearings 23. The outlet end of the collection hose 5 is connected to the end of the reel 21 and the discharge channel embedded in the baffle 22. The discharge channel is connected to the water pump 14 through a discharge pipe 24. Figure 5As shown, the discharge channel includes a water outlet 25, a drainage groove 26, and a guide hole 27. The guide hole 27 is disposed through the truncated cone at the end of the reel 21. The drainage groove 26 is disposed inside the baffle 26. The end face of the drainage groove 26 is rotatably engaged with the truncated cone at the end of the reel 21 and is sealed by a sealing ring 31. The water outlet 25 is disposed at the bottom of the drainage groove 26, and the outlet of the water outlet 25 is connected to the discharge pipe 24.

[0034] To further optimize the above structure, a limiting plate 36 is installed below the reel 21. The limiting plate 36 is fixed to the bottom of the baffle 22, and the limiting plate 36 has a long strip-shaped limiting hole in the middle for the collection hose 5 to pass through. The limiting hole can limit the collection hose and prevent the collection hose 5 from swinging too much relative to the reel 21 during the winding and unwinding process.

[0035] The aforementioned nuclear, biological, and chemical liquid sampling device is suitable for water sample collection in different areas. However, soil sampling is different; when sampling soil from non-planar plots, the sampling angle of the sampling claw needs to be adjusted. In specific design, such as... Figure 3 As shown, the rotating component is connected to the mounting frame 6 via a swing mechanism. The swing mechanism includes a swing motor 32, a swing arm 33, and a mounting plate 34. The swing motor 32 and its two end drive shafts 35 are connected to the mounting frame 6. The drive shafts 35 are connected to the swing arm 33, and the lower end of the swing arm 33 is connected to the mounting plate 34. The rotating component is located at the bottom of the mounting plate 34. This structure facilitates soil sampling on slopes. The angle of the UAV can be pre-adjusted to allow the sampling claw to rotate perpendicular to the soil surface, and then the rotating component can be driven to perform sampling. Furthermore, the telescopic arm has two or more sections and can be hydraulically or electrically driven, allowing for fine-tuning of the sampling claw length during sampling.

[0036] To further optimize the above solution, the top of the drone 3 is equipped with a wind speed and direction sensor 28, which is wirelessly connected to the remote controller. Simultaneously, the bottom of the drone 3 is equipped with three or more support legs 29, and the bottom of each support leg 29 is equipped with a foot pad 30 to provide support when the drone descends and lands, thus providing support for the nuclear, biological, and chemical soil sampling device when digging for soil samples and ensuring stability during the sampling process.

[0037] In practical implementation, the parameters of the toxic gas detection sensor are as follows: gas collection capacity of 1-5 liters, collection flow rate of 1L / min; capable of detecting toxic gases (Sarin GB, Soman GD, V% V, mustard gas H), detection range: 1-30ppm, response time: 10s.

[0038] The thermal imaging reconnaissance device can determine the observation altitude from the air based on the size of the person's own heat source. Temperature measurement methods include point measurement and area measurement. Measurement range: -20℃ to 150℃ (high gain mode), 0℃ to 500℃ (low gain mode); digital zoom: 28x; infrared wavelength: 8μm to 14μm; infrared temperature measurement accuracy: ±2°.

[0039] The wind direction and speed sensor can withstand gusts up to level 6. The wind speed measurement range is 0-60m / s, with an accuracy of ±3x and a resolution of 0.1m / s; the wind direction measurement range is 0-359°, with an accuracy of ±3° and a resolution of 1°.

[0040] The collection tank of the nuclear, biological and chemical liquid collection device 100 has a volume of 1-5 liters and is fully sealed; the collection hose has a lifting length of 10 meters and a retraction speed of 0.1-0.1 m / min.

[0041] The sampling claw of the nuclear, biological and chemical soil sampling device 200 can swing freely to adapt to soil sampling operations at different angles on the ground, and the extension range of the sampling claw is 390mm-800mm.

[0042] In summary, this invention boasts advantages such as simple and compact structure, convenient remote operation, and high safety. It allows for remote control of a drone equipped with a toxic gas detection sensor and a thermal imaging reconnaissance device to conduct chemical reconnaissance of contaminated areas. This facilitates the detection of toxic gases and the determination of personnel locations in the reconnaissance area from high altitude. Simultaneously, it utilizes nuclear, biological, and chemical liquid and soil sampling devices to collect water and soil samples, enabling a thorough understanding of the contamination situation and timely intervention. This invention obtains reconnaissance data without requiring personnel to enter the site, saving time and effort and providing strong technical support for minimizing personal injury and property damage.
