[0027] Embodiment 1

[0028] As Figures 1-5 shown, the present utility model provides a dust collection device for environmental monitoring, including an assembly frame 1. The upper surface of the assembly frame 1 is fixedly connected with a collection box 2. The center of one side of the assembly frame 1 is fixedly connected with a height-adjusting electric push rod 6. The top of the height-adjusting electric push rod 6 is fixedly connected with a built-in rod 11. The outer wall of the built-in rod 11 is slidably sleeved with a collar 14. The outer wall of the collar 14 is slidably connected with a positioning sleeve 10. The outer wall of the built-in rod 11 is provided with a positioning hole 12.

[0029] One side of the collar 14 is fixedly connected with an installation box 15. One end of the installation box 15 is fixedly connected with a first collection pipe 3. One side of the first collection pipe 3 is fixedly connected with the collection box 2 through a hose 25 connected thereto. The second collection pipe 4 and the third collection pipe 5 are sequentially arranged below the first collection pipe 3.

[0030] The inner wall of the installation box 15 is fixedly connected with an electromagnet 17, and the inner wall of the electromagnet 17 is slidably connected with an insertion column 18. One end of the insertion column 18 movably penetrates into the inside of the collar 14.

[0031] Embodiment 2

[0032] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, both the second collection pipe 4 and the third collection pipe 5 are fixedly connected with an installation box 15 and a collar 14. One side of the collar 14 is fixedly connected with a slider 16, and the outer wall of the slider 16 is fixedly connected with a solenoid valve 7.

[0033] One end of the insertion column 18 is fixedly connected with a return spring 19, and one end of the return spring 19 is fixedly connected with the inner wall of the installation box 15.

[0034] Embodiment 3

[0035] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a positioning groove 13 is provided on one side of the positioning sleeve 10. One side of the collar 14 is fixedly connected with a slider 16, and the outer wall of the slider 16 is slidably connected with the inner wall of the positioning groove 13. The outer wall of the built-in rod 11 is movably connected with a top ring, and the outer wall of the top ring is fixedly connected with the inner wall of the top end of the positioning sleeve 10.

[0036] The outer wall of one end of the insertion column 18 is movably inserted into the inner wall of the positioning hole 12. The inside of the collection box 2 is respectively separated by a partition board into storage chambers 20 corresponding to the first collection pipe 3, the second collection pipe 4, and the third collection pipe 5. The inner wall of the storage chamber 20 is movably connected with a piston plate 21, and one side of the piston plate 21 is fixedly connected with a connecting rod 23. When sucking and collecting dust in the air through the first collection pipe 3, the side-positioned electric push rod 24 is started, so that the side-positioned electric push rod 24 pulls the connecting rod 23 to drive the piston plate 21 to move in the storage chamber 20, so that a negative pressure is generated inside the storage chamber 20, and then the dust in the air is sucked and collected. The second collection pipe 4 and the third collection pipe 5 can similarly suck and collect the corresponding dust in the air according to the power generated by the drive of the corresponding side-positioned electric push rod 24.

[0037] The sides of the storage chamber 20 are separated by the piston plate 21 and are respectively provided with pipes for discharging dust and air. When it is necessary to discharge the dust in the storage chamber 20, the side-positioned electric push rod 24 is started, and the piston plate 21 is moved to the left, squeezing the dust and discharging it through the pipe to the detection equipment connected thereto for detection. Since the piston plate 21 moves left and right on the inner wall of the storage chamber 20 to squeeze the air, the dust therein can be discharged cleanly, facilitating the subsequent storage of different dust samples.

[0038] One end of the connecting rod 23 is fixedly connected with a connecting frame 22. Both ends of the connecting frame 22 are fixedly connected with side electric push rods 24. The upper surface of the assembly frame 1 is fixedly connected with a controller 8. One side of the assembly frame 1 is fixedly connected with a push handle 9. The bottom end of the assembly frame 1 is fixedly connected with universal wheels.

[0039] Next, the working principle of the dust collection device for environmental monitoring will be specifically described.

[0040] As Figures 1-5 shown, when it is necessary to adjust the dust suction at a specified position of the first collection tube 3, the electromagnet 17 is activated through the controller 8 to generate a magnetic force to push the plug column 18 into the positioning hole 12. Then, the height adjustment electric push rod 6 is activated to push the built-in rod 11 upward. During the upward movement of the built-in rod 11, the collar 14 is driven to move upward through the plug column 18. The collar 14 drives the first collection tube 3 to move upward to a suitable position and then stops. When the position of the second collection tube 4 needs to be adjusted, the corresponding electromagnet 17 is also activated and then inserted onto the built-in rod 11 and moves upward under the drive of the built-in rod 11 to a suitable position. When the installation box 15 moves, the electromagnet 17 can stop operating.

[0041] When it is necessary to reset the first collection tube 3 and the second collection tube 4, the height adjustment electric push rod 6 can be used to pull the built-in rod 11 downward. When the installation box 15 is reset, the plug column 18 can be reset under the pull of the reset spring 19 and disengaged from the positioning hole 12.

[0042] When sucking and collecting dust in the air through the first collection tube 3, the side electric push rod 24 is activated, so that the side electric push rod 24 pulls the connecting rod 23 to drive the piston plate 21 to move in the storage chamber 20, causing a negative pressure inside the storage chamber 20, thereby sucking and collecting the dust in the air. The second collection tube 4 and the third collection tube 5 can similarly suck and collect the corresponding dust in the air according to the power generated by the drive of the corresponding side electric push rod 24.

[0043] In general, the above has described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
