DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0023] The utility model provides a technical solution: Figure 1-2 , Figure 4 As shown, in the present embodiment, an air gas sampling device mounted on a drone includes a drone body 100 and a telescopic assembly 200 of a gas sampling mechanism, wherein the drone body 100 includes a chassis 101 installed thereon, and the telescopic assembly 200 of the gas sampling mechanism includes a fixed block 201, wherein the fixed block 201 is connected to both side ends inside the chassis 101 by welding, wherein the interior of the fixed block 201 is connected with a rotating bolt 202 by penetration, and the outer side of the rotating bolt 202 is connected with a connecting block 211 by rotation, and one end of the connecting block 211 is connected and fixed to a telescopic hydraulic cylinder 210 by bolts, and a telescopic guide column 209 is installed inside the telescopic hydraulic cylinder 210, and one end of the telescopic guide column 209 is connected to the outer end of a rotating pin 208 by bolts, and the rotating pin 208 is connected to the interior of the fixed block 201 by penetration, and the fixed block 201 is connected to one end side of a gas sampling body 206 by welding.
[0024] like Figure 4 As shown, a gas sampling hole 207 is provided at one end of the gas sampling body 206, and movable bolts 205 are installed on both side ends of the gas sampling body 206. The movable bolts 205 are connected to the inside of the first connecting rod 203 and the second connecting rod 204 by rotation. The inside of one end of the first connecting rod 203 and the second connecting rod 204 is connected to the rotating bolt 202 by rotation, and the rotating bolt 202 is connected to the inside of the fixed block 201 through a penetration.
[0025] The drone is started and operated, and the air gas sampling device is used to sample the air gas. When the gas sampling device is completed, the telescopic guide column 209 is moved by driving the telescopic hydraulic cylinder 210. When the telescopic guide column 209 retracts inwardly inside the telescopic hydraulic cylinder 210, the rotating latch 208 on the telescopic guide column 209 rotates on the fixed block 201, and the gas sampling body 206 moves upward and moves into the chassis 101. The connecting block 211 at one end of the telescopic hydraulic cylinder 210 rotates on the rotating bolt 202. When the gas sampling body 206 moves upward, it further drives the first connecting rod 203 and the second connecting rod 204. The connecting rod 204 moves upward, and drives the first connecting rod 203 and the second connecting rod 204 to rotate through the movable bolt 205. At the same time, the first connecting rod 203 and the second connecting rod 204 are driven to rotate through the rotating bolt 202. By moving the gas sampling device to the inside of the drone chassis 101, it can avoid vibration and impact on the gas sampling device during long-term flight of the drone, and avoid loosening or falling off of the connecting parts of the gas sampling device, thereby affecting the stability of the gas sampling device. Moving the gas sampling device into the chassis 101 can provide better protection measures to prevent external environmental factors from causing damage to the gas sampling device.
[0026] like Figure 1 , Figure 3 , Figure 5 As shown, brackets 103 are connected to both sides of the chassis 101 by welding, and the lower end of the bracket 103 is fixed to the floor panel 102 by bolts. Sliding grooves 301 are provided inside the lower end of the chassis 101 on both sides, and the first sliding rod 302 and the second sliding rod 303 are connected inside the sliding grooves 301 by sliding. Sliding through holes 304 are provided inside the first sliding rod 302 and the second sliding rod 303. A screw rod 305 is connected inside the first sliding rod 302 by rotation, and an electric motor 306 is installed at one end of the screw rod 305. The electric motor 306 is connected to one end of the chassis 101 by bolts. A support guide column 307 is connected inside the second sliding rod 303 by sliding, and a mounting plate 308 is installed at one end of the support guide column 307. The lower ends of the first sliding rod 302 and the second sliding rod 303 are connected and fixed to the closed door 309 by welding.
[0027] When the gas sampling device is recovered into the UAV chassis 101, the electric motor 306 is driven to drive the screw rod 305 to rotate inside the first sliding rod 302, and the rotation of the screw rod 305 further drives the first sliding rod 302 and the second sliding rod 303 to move. The movement of the first sliding rod 302 and the second sliding rod 303 further drives the closed door 309 to move. The lower end of the UAV chassis 101 is closed by the movement of the closed door 309. By closing the lower end opening of the UAV chassis 101, the gas sampling device can be effectively protected from external factors, such as bad weather, accidental collisions, etc., which helps to reduce the possibility of damage to the gas sampling device and ensure the safety of the sampling process.
[0028] The utility model provides an air gas sampling device mounted on a drone, and the specific working principle is as follows: the drone is started and operated, and the air gas sampling device is used to sample the air gas. When the gas sampling device is completed, the telescopic guide column 209 is driven to move by driving the telescopic hydraulic cylinder 210. When the telescopic guide column 209 is retracted inwardly inside the telescopic hydraulic cylinder 210, the rotating pin 208 on the telescopic guide column 209 rotates on the fixed block 201, and at the same time, the gas sampling body 206 moves upward and moves into the inside of the chassis 101. The connecting block 211 at one end of the telescopic hydraulic cylinder 210 rotates on the rotating bolt 202. When the gas sampling body 206 moves upward, it further drives the first connecting rod 203 and the second connecting rod 204 to move. The movable bolt 205 drives the first connecting rod 203 and the second connecting rod 204 to rotate, and the rotating bolt 202 drives the first connecting rod 203 and the second connecting rod 204 to rotate. The gas sampling device is moved to the inside of the UAV chassis 101. When the gas sampling device is recovered to the inside of the UAV chassis 101, the electric motor 306 drives the screw rod 305 to rotate inside the first sliding rod 302. The rotation of the screw rod 305 further drives the first sliding rod 302 and the second sliding rod 303 to move. The movement of the first sliding rod 302 and the second sliding rod 303 further drives the closed door 309 to move. The lower end of the chassis 101 of the UAV is closed by the movement of the closed door 309.
