[0016] 3. The present invention adopts a collection detection component to make the air sucked in by the upper vertical pipe enter into the hose, and the air sucked in by the lower vertical pipe enter into the connecting hose. The hose and the connecting hose collect the air into the collection pipe, and the two horizontal pipes respectively fill the inhaled air into the two suction hoses, and then fill the air into the collection pipe through the two suction hoses. The dust concentration sensor monitors the dust concentration, and can collect and detect the air sucked in a large area horizontally and vertically, thereby improving the detection range;

In summary, according to the detection needs, large-area detection of air in the vertical range and the horizontal range can be achieved, and the detection range is wider.

[0037] In this technical solution, as shown in the attached Figure 4-12 As shown, the collection detection assembly includes a collection suction pipe 35 fixedly installed on one side of the detection housing 1; the collection suction pipe 35 is connected to the detection housing 1, and a hose 36 is fixedly connected to the top of the outer wall of the collection suction pipe 35, and a connecting hose 37 is fixedly connected to one end of the collection suction pipe 35; the hose 36 is fixedly connected to the vertical suction pipe 13, and the bottom end of the connecting hose 37 is fixedly connected to another vertical suction pipe 13, and a threaded tube 38 with a threaded connection is embedded in the other side of the detection housing 1, and a negative pressure pump 39 is fixedly installed at one end of the threaded tube 38, and the negative pressure pump 39 is used for negative pressure air, and a filter 40 is fixedly installed on the inner wall of the threaded tube 38; a dust concentration sensor 41 is fixedly installed on one side of the inner wall of the detection housing 1. The collection suction pipe 35 is connected to the detection housing 1, and the collection suction pipe 35 and the inner wall of the detection housing 1 are polished.

[0038] The working method of the environment detection device for dust environment in this embodiment is as follows:

[0039] Step 1: During the vertical displacement detection, the operator installs the mounting bracket 14 on the steel beam in the dust environment by bolts, and fixes the mounting bracket 14. The mounting bracket 14 can support the detection housing 1 and increase the stability of the detection housing 1. The negative pressure pump 39 can be started by the controller 16 to generate negative pressure suction, and then the drive motor 5 is started by the controller 16. The drive motor 5 drives the screw 4 to rotate forward inside the sliding frame 3. The screw 4 carries two sleeves 6 to approach each other under the action of the thread transmission force, and the two sleeves 6 respectively carry two racks 8 to approach each other. The distance between the two sleeves 6 is reduced, the rack 8 carries the gear ring 9 to rotate, the gear ring 9 carries the rotating shaft 10 to rotate on the protective frame 2, and the rotating shaft 10 rotates inside the concave sleeve 11 at the same time, and the detection housing 1 can support the two concave sleeves 11, so that the rotating shaft 10 carries the rotating ring 12 to rotate, and the rotating ring 12 drives the vertical suction pipe 13 to rotate. The upper vertical straw 13 can rotate counterclockwise, while the lower vertical straw 13 can rotate clockwise. The two vertical straws 13 can vertically inhale air over a large area, and the air enters the two vertical straws 13 .

[0040] Step 2, during the displacement switching detection, the upper sleeve block 6 can approach the first displacement distance sensor 7. When the distance sensed by the first displacement distance sensor 7 is the same as the distance sensed by the controller 16, the drive motor 5 is started by the controller 16, and the drive motor 5 drives the screw 4 to reverse, so that the two sleeve blocks 6 move away from each other, thereby increasing the distance between the two sleeve blocks 6. The two sleeve blocks 6 carry two racks 8 to move respectively, and the distance between the two racks 8 increases. The two gear rings 9 rotate synchronously, and the gear ring 9 carries the rotating shaft 10 to rotate inside the concave sleeve block 11. The rotating shaft 10 drives the rotating ring 12 to rotate the vertical straw 13. The upper vertical straw 13 can rotate clockwise, while the lower vertical straw 13 can rotate counterclockwise. The two vertical straws 13 can inhale air over a large area within the vertical range.

[0041] Step 3: During the lateral displacement detection, the reduction motor 20 is started through the controller 16, and the reduction motor 20 drives the transmission screw 19 to rotate forward. The transmission screw 19 drives the sleeve block 21 to move rightward under the action of the thread transmission force, so that the sleeve block 21 carries the two concave blocks 23 to move rightward synchronously, and the two concave blocks 23 respectively carry the two linkage shafts 24 to move rightward, and the linkage shaft 24 drives the sleeve rod 25 to move, and the sleeve rod 25 carries the linkage rack 27 to approach the support frame 18, and at the same time, the linkage rack 27 drives the sliding sleeve block 33 to move, and the sliding sleeve block 33 can slide on the outer wall of the sliding column 34. In this way, the sliding sleeve 33 can move closer to the support frame 18, and the linkage rack 27 drives the transmission gear ring 28 to rotate. The transmission gear ring 28 causes the rotating rod 29 to rotate on the protective side frame 17. The rotating rod 29 also drives the rotating ring 30 to rotate. The rotating ring 30 drives the transverse suction pipe 31 to rotate. The front transverse suction pipe 31 can rotate counterclockwise, and the rear transverse suction pipe 31 can rotate clockwise. The two transverse suction pipes 31 can inhale air in a large area horizontally.

[0042] Step 4, during precise displacement, the sleeve block 21 approaches the position of the second displacement distance sensor 22. When the distance sensed by the second displacement distance sensor 22 is the same as the distance set by the controller 16, the reduction motor 20 is started through the controller 16. The reduction motor 20 drives the transmission screw 19 to reverse. The transmission screw 19 carries the sleeve block 21 to move leftward under the action of the thread transmission force. The sleeve block 21 also carries the two concave blocks 23 to move leftward. The two concave blocks 23 respectively carry the two linkage shafts 24 to move leftward. The linkage shaft 24 drives the sleeve rod 25 to move. The sleeve rod 25 carries the connecting column 26 away from the support frame 18. At the same time, the two protective side frames 17 move away from the support frame 18. The distance between the two protective side frames 17 increases. The protective side frame 17 carries the transmission gear ring 28 to rotate. The transmission gear ring 28 drives the rotating rod 29 to rotate the transverse suction pipe 31. The front transverse suction pipe 31 rotates clockwise, while the rear transverse suction pipe 31 rotates counterclockwise. The two transverse suction pipes 31 can be displaced laterally to inhale air.

[0043] Step 5. During the collection detection, the air sucked in by the upper vertical pipette 13 enters the hose 36, and the air sucked in by the lower vertical pipette 13 enters the connecting hose 37. The air is collected into the collecting pipette 35 through the hose 36 and the connecting hose 37. The two horizontal pipettes 31 respectively inject the inhaled air into the two suction hoses 32, and then inject the air into the collecting pipette 35 through the two suction hoses 32. The air is collected into the detection shell 1 through the collecting pipette 35. The dust concentration sensor 41 inside the detection shell 1 senses the dust concentration, and determines whether the sensed value is the same as the concentration value set by the detection host 15. If they are the same, the detection host 15 maintains normal operation. If they are not the same, the detection host 15 will issue an alarm, and the negative pressure pump 39 will suck the air inside the detection shell 1 into the threaded pipe 38, which is filtered by the filter 40. In this way, the air is discharged externally, completing the environmental detection operation in a dusty environment.
