Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1:

[0040] As Figure 1-6 shown:

[0041] The bottom of the box body 1 is open, and an elastic reset component and a cover plate 5 are installed at the open bottom of the box body 1. The cover plate 5 is driven by the elastic reset component to open or close the opening at the bottom of the box body 1;

[0042] When the opening at the bottom of the box body 1 is closed, the inverted U-shaped plate 6, the first vertical moving component, the second moving wheel 26, the support plate 8, the second vertical moving component, the first slider, the second slider, the transverse moving component, the collection shovel 14, and the collection box 16 are all located inside the box body 1. At this time, the box body 1 moves its position through the first moving wheel 32 at the bottom of the cover plate 5;

[0043] The first vertical moving component is installed on the inner top wall of the box body 1. The first vertical moving component drives the inverted U-shaped plate 6 to move downward to push open the cover plate 5. The cover plate 5 opens the bottom opening of the box body 1 and extends downward from the bottom opening of the box body 1. At this time, the second moving wheel 26 at the bottom of the inverted U-shaped plate 6 abuts against the ground;

[0044] The second vertical moving component is installed on the inner top wall of the inverted U-shaped plate 6. The second vertical moving component drives the support plate 8 to move vertically downward, so that the collection shovel 14 and the collection box 16 extend out from the bottom opening of the box body 1 and descend to the set working height;

[0045] After that, the transverse moving component drives the first slider and the second slider to slide horizontally and linearly on the support plate 8 and approach each other, so that the collection shovel 14 and the collection box 16 with matching structures approach each other. The collection shovel 14 and the collection box 16 approaching each other realize the collection of samples at the fire scene.

[0046] Embodiment 2, improved on the basis of Embodiment 1:

[0047] Refer to Figure 1 - Figure 6, a fire scene sample collection device, comprising a box body 1. At the bottom of the outer walls on both sides of the box body 1, two support rods 2 are fixed by bolts. A rotating sleeve 3 is rotatably connected between the two support rods 2. Torsion springs 4 are sleeved at both ends of the rotating sleeve 3. A cover plate 5 is welded to the outer wall of the rotating sleeve 3. The cover plate 5 covers the bottom of the box body 1.

One end of the hydraulic rod of the first hydraulic cylinder 27 is fixedly connected with the inverted U-shaped plate 6. The first hydraulic cylinder 27 drives the inverted U-shaped plate 6 to move. The top inner wall of the box body 1 is fixed with two first telescopic rods 28 by bolts. The bottom ends of the first telescopic rods 28 are fixedly connected with the inverted U-shaped plate 6. The top inner wall of the inverted U-shaped plate 6 is fixed with a second hydraulic cylinder 29 by bolts.

Push the box body 1 to make the first moving wheels 32 roll on the ground, so as to push the sample collection device to the fire scene.

[0050] Working principle of this embodiment: When in use, first, push the box body 1 to roll on the ground through the first moving wheels 32, so as to push the sample collection device to the fire scene. Then, rotate the rotating screw 36 to make the top frame 37 slide downward to abut against the ground, lift the box body 1 to an appropriate height, and at the same time make the first moving wheels 32 leave the ground. Then, drive the inverted U-shaped plate 6 to move downward under the drive of the first hydraulic cylinder 27, so that the cover plate 5 opens outward, and further makes the second moving wheels 26 contact the ground. Then, push the box body 1 to make the second moving wheels 26 roll on the ground, so as to drive the sample collection device to move. When collecting samples, drive the connecting plate 7 to move downward under the drive of the second hydraulic cylinder 29, so as to drive the collecting shovel 14 and the collecting box 16 to move downward to contact the ground.
