[0027] like Figure 1 As shown, this embodiment discloses an atmospheric environment sample collection device based on a UAV platform, including a UAV body 1, a pod 2, a power assembly 3 and a vacuum sampling assembly 4. The pod 2 is arranged at the belly of the UAV body 1; the power assembly 3 is arranged at the end of the pod 2; and the vacuum sampling assembly 4 is arranged in the pod 2.

[0028] like Figure 2As shown, the vacuum sampling component 4 includes a vacuum sampling container 401, a negative pressure sampling port 402 is provided on the vacuum sampling container 401, a sealing plug 403 is provided on the negative pressure sampling port 402, a pull rod 404 is provided on the sealing plug 403, a spring 405 is sleeved on the pull rod 404, one end of the spring 405 rests on the sealing plug 403, and the other end rests on a support plate 406, the support plate 406 is connected to the vacuum sampling container 401 through brackets 407 on both sides, a guide hole 408 is provided on the support plate 406, and the outer end of the pull rod 404 passes through the guide hole 408 and is connected to the power component 3.

[0029] Under natural conditions, the sealing plug 403 presses against the negative pressure sampling port 402, so that the vacuum sampling container 401 is always in a vacuum state. During sampling, the pull rod 404 is pulled outward by the power component 3 to release the sealing plug 403 and the negative pressure sampling port 402. After the outside gas enters the vacuum sampling container 401 under the action of atmospheric pressure, the power component 3 is reset, and the sealing plug 403 continues to seal against the negative pressure sampling port 402 under the action of the spring 405, thus completing the sampling work.

[0030] Before use, the vacuum sampling component 4 evacuates the interior of the vacuum sampling container 401 through an external vacuum pump. Therefore, in this embodiment, a charging and discharging air pipe 409 is provided on the vacuum sampling container 401 , and a gas valve 410 is provided on the charging and discharging air pipe 409 .

[0031] like Figure 3 As shown, the pod 2 includes a cabin body 201, a vacuum sampling container 401 is arranged in the cabin body 201, a connecting seat 202 is arranged on the top of the cabin body 201, and the connecting seat 202 is connected to the belly of the drone body 1 by bolts.

[0032] Since the vacuum sampling container 401 needs to be placed in the cabin 201, the cabin 201 and the vacuum sampling container 401 have the same outer shape. In the present embodiment, the cabin 201 and the vacuum sampling container 401 are both cylindrical structures, and the air filling and discharging pipe 409 on the vacuum sampling container 401 can be inflated and deflated from the rear of the cabin 201.

[0033] Based on the vacuum sampling container 401 with a cylindrical structure, the negative pressure sampling port 402 is opened at one end of the vacuum sampling container 401 , and the filling and discharging air pipe 409 is arranged at the other end of the vacuum sampling container 401 .

[0034] In order to fix the vacuum sampling container 401 on the cabin 201, Figure 4As shown, a limit fixing plate 406-1 is provided at the bottom of the support plate 406, and a connecting plate 201-1 is provided on the outer wall of the cabin 201. When the vacuum sampling container 401 is placed in the cabin 201, the limit fixing plate 406-1 abuts against the connecting plate 201-1, and the two are fixed by bolts.

[0035] like Figure 5 As shown, the power assembly 3 includes a steering gear 301 , which is fixedly mounted on the end of the connecting seat 202 , and the power output shaft of the steering gear 301 drives the pull rod 404 to slide outward through the connecting rod assembly 302 .

[0036] In this embodiment, the connecting rod assembly 302 includes a swing arm 302-1, which is fixed on the power output shaft of the servo 301. The swing end of the swing arm 302-1 is hinged with a sliding sleeve 302-6, and the sliding sleeve 302-6 is slidably mounted on the shift rod 302-2. The lower end of the shift rod 302-2 is fixedly connected to the shift fork 302-3. The shift fork 302-3 has a door-shaped structure. The lower ends of the two vertical parts of the shift fork 302-3 are hinged on the support plate 406, and the two vertical parts of the shift fork 302-3 are provided with sliding holes 302-4, and a shift shaft 302-5 is provided in the sliding hole 302-4. The shift shaft 302-5 is fixed on the pull rod 404.

[0037] When the power assembly 3 is working, the servo 301 drives the swing arm 302-1 to swing, thereby driving the fork 302-3 to swing around the hinge shaft below. While the fork 302-3 rotates, it drives the shift shaft 302-5 in the sliding hole 302-4 to stretch the pull rod 404 outward, thereby releasing the sealed state between the sealing plug 403 and the negative pressure sampling port 402.

[0038] In this embodiment, the drone body 1 is a multi-rotor drone, and two pods 2 are arranged on the belly of the drone body 1 . A camera device 5 is arranged between the two pods 2 , and the camera device 5 is arranged on the drone body 1 .

[0039] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
