When the strip tooth plate 24 needs to be unlocked, the telescopic end of the micro electric telescopic rod 29 is controlled by the external remote controller to contract so that the fixing rod 30 is separated from the fixing hole 28, thereby unlocking the strip tooth plate 24).

[0035] In the present invention, an air guide scoop 10 is provided at one end of the air inlet hole of the dust monitor body 4, and the air guide scoop 10 is funnel-shaped, which is convenient for wind to enter the air inlet hole of the dust monitor body 4, thereby facilitating the dust monitor body 4 to monitor dust; an air volume monitor 11 (the prior art) is installed in the air guide scoop 10, which is convenient for monitoring the wind entering the air inlet hole of the dust monitor body 4, so as to determine the rotation angle of the dust monitor body 4; a fan 3 is installed at the other end of the air inlet hole of the dust monitor body 4 through a bracket 2, which is convenient for blowing air into the air inlet hole of the dust monitor body 4 in a windless environment, so that dust enters the air inlet hole of the dust monitor body 4, ensuring that the dust monitor body 4 can accurately measure the dust data in the air in a windless or windy environment; a rectangular plate 2 32 is provided in the box body 1, and a rectangular plate 32 is provided in the box body 1. A pressure sensor 31 is provided on plate 2 32, wherein when the bar-shaped tooth plate 17 contacts the pressure sensor 31, the air volume monitor 11 rotates 360°; the box body 1 is installed with a control device 20 that cooperates with the air volume monitor 11 and the pressure sensor 31; wherein, through the coordinated use of the pressure sensor 31, the control device 20 and the fan 3, it is convenient to blow air into the air duct of the dust monitor body 4 in a windless environment, so that dust can enter the dust monitor body 4, thereby facilitating dust monitoring and ensuring the accuracy of dust data in a windless environment; the control device 20 includes a processor and a controller, and the processor is connected to the air volume monitor 11 and the pressure sensor 31 by wires, and the electric push rod 16 and the fan 3 are electrically connected to the controller by wires.

[0036] In the present invention, the stabilizing member includes two groups of support plates 2 symmetrically arranged on the box body 1, a guide rod 9 is provided between each group of support plates 2, a slider 22 is slidably provided on the outer wall of the guide rod 9, and a bracket 8 is movably hinged between the slider 22 and the cylindrical tube 6, which is convenient for the sliding and limiting of the bracket 8, thereby facilitating the stable lifting and lowering of the cylindrical tube 6.

[0037] In the present invention, a plurality of limit strips 21 are evenly arranged on the outer wall of the connecting shaft 13, and a limit groove is provided on the inner wall of the hollow shaft 19 to cooperate with the limit strips 21, so that the hollow shaft 19 can drive the connecting shaft 13 to rotate when rotating.

[0038] Working principle: When the present invention is used to monitor dust in the air, the electric push rod 16 is first turned on, and the rectangular frame 25 is driven to move by the extension of the telescopic end of the electric push rod 16. The movement of the rectangular frame 25 is divided into two processes:

[0039] Process 1: Under the action of the extrusion spring 26, the movement of the rectangular frame 25 will drive the movable block 27 to move, and then drive the bar-shaped toothed plate 24 to move, thereby driving the gear 23 and the screw 14 to rotate; then the bracket 8 limits the cylindrical barrel 6, so that the cylindrical barrel 6 will not rotate with the rotation of the screw 14, so the threaded sleeve 15 will not rotate with the screw 14, thereby realizing the lifting of the cylindrical barrel 6, and the lifting of the cylindrical barrel 6 drives the rectangular plate 5 and the mounting plate 12 to lift, thereby realizing the lifting of the dust monitor body 4, realizing the monitoring of air at different heights, improving the versatility of the dust monitoring device, and further facilitating the monitoring of dust at the construction site;

[0040] After the dust monitor body 4 is adjusted to a suitable position, the fixing rod 30 is inserted into the fixing hole 28 by extending the telescopic end of the micro electric telescopic rod 29, so as to limit the position of the second strip tooth plate 24, and prevent the second strip tooth plate 24 from moving with the rectangular frame 25, thereby fixing the position of the dust monitor body 4;

[0041] Process 2: As the rectangular frame 25 continues to move, the bar-shaped toothed plate 17 meshes with the gear 18 and causes the gear 18 to rotate, thereby driving the hollow shaft 19 to rotate, and then the connecting shaft 13 rotates with the cooperation of the limit bar 21, thereby driving the mounting plate 12 to rotate, and further driving the dust monitoring instrument body 4, so as to find the direction of wind flow, thereby facilitating dust monitoring;

[0042] As the dust monitor body 4 rotates, when the air inlet holes of the dust monitor body 4 are aligned with the flow direction of the wind, the wind will pass through the air inlet holes of the dust monitor body 4, and then the air volume monitor 11 will monitor the wind, and then the air volume monitor 11 will transmit the signal to the processor in the control device 20, and the processor processes and controls the telescopic end of the electric push rod 16 to stop extending through the controller; the dust is driven into the air volume monitor 11 by the wind, and then the dust is monitored;

[0043] Among them, when the wind volume monitor 11 rotates 360° and the wind volume monitor 11 still does not monitor the wind, at this time, the bar tooth plate 17 will contact the pressure sensor 31, and then the pressure sensor 31 will transmit the signal to the control device 20, which will be processed by the processor in the control device 20 and turned on by the controller. Then the fan 3 will blow air into the air duct of the dust monitor body 4, which is convenient for monitoring the dust and improving the work efficiency of dust monitoring.

[0044] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
