The specific implementation manner of this embodiment is:
an operator locates the machine room environment monitoring device provided by the scheme in a machine room by means of fixing pieces such as screws, and in an initial state, the dust return prevention turning plate 152 naturally droops under the action of gravity and is attached to the inner wall of the one-way dust collecting cylinder 15, the dust return prevention turning plate 152 enables air flow to enter the one-way dust collecting cylinder 15 from one side of the filter plate 2 through the dust collecting air flow hole 151 and cannot reversely circulate, the exhaust turning plate 131 naturally droops under the action of gravity and is attached to the outer wall of the one-way exhaust valve 13, and the air inlet turning plate 141 seals the upper end of the one-way air inlet valve 14 under the thrust action of the reset sealing spring 142.
After the equipment starts to operate, the display controller 3 is powered on, the bidirectional fan 12 starts to operate, under the monitoring working condition, the operation mode of the bidirectional fan 12 enables air flow to flow along the directions of the one-way air inlet valve 14, the filter plate 2 and the bidirectional fan 12, at the moment, the air pressure in the force measuring air cylinder 1 is reduced, the air inlet turning plate 141 rotates due to the action of negative pressure and enables the one-way air inlet valve 14 to be in an opening state, the dust return prevention turning plate 152 is tightly attached to the inner wall of the one-way dust collecting cylinder 15 due to the action of negative pressure, the one-way dust collecting cylinder 15 and the force measuring air cylinder 1 are in an isolated state, along with the continuous monitoring, air carrying dust gradually enters the air cylinder force measuring 1, the dust is gradually filtered and intercepted by the filter plate 2, the two sides of the filter plate 2 slide to one side of the bidirectional fan 12 along the inner wall of the force measuring air cylinder 1 due to the pressure difference, in the process, the force measuring rod 11 gradually compresses the force measuring spring 221 by the movement of the sliding force measuring cylinder 22, therefore, the force-measuring pressure block 111 compresses the stress sheet 1111, the generated stress data is collected by the stress collector 31 and fed back to the display screen 33, in an ideal state, namely, in a dust-free environment, the bidirectional fan 12 stably operates, the generated air flow velocity is unchanged, after the filter plate 2 slides for a certain distance, the elastic force provided by the force-measuring spring 221 is balanced with the air pressure acting force, the filter plate stops continuously sliding and keeps a static state, and dust exists in a machine room, therefore, when the dust amount accumulated on the side wall of the filter plate 2 is gradually increased, the number of the through micro air holes 21 on the filter plate 2 is gradually reduced, the air flow velocity and the air flow amount generated by the bidirectional fan 12 are unchanged, in order to realize the balance of the air amount, the speed of the air passing through the single micro air hole 21 is gradually increased, therefore, the air pressure acting force is gradually increased, so that the filter plate continuously slides and continuously compresses the force-measuring spring 221, therefore, the stress borne by the stress sheet 1111 is increased continuously, the rate of increase of the stress sheet 1111 can indicate the dust concentration, the higher the dust concentration is, the faster the rate of increase of the stress is, and when the rate exceeds the limit value, the alarm 17 will give out an alarm sound.
After the equipment runs for a period of time, more dust is accumulated on the filter plate 2, and the dust monitoring is difficult to continue effectively, at the moment, an operator controls the reverse running of the bidirectional fan 12 through the control panel 32 to generate reverse airflow, the equipment enters an auxiliary dust collection working condition, under the working condition, the air pressure inside the force measurement air cylinder 1 is increased, the upper end of the unidirectional air inlet valve 14 is sealed by the air inlet turning plate 141, the dust return prevention turning plate 152 rotates under the action of the air pressure and enables the dust collection airflow hole 151 to be opened, the dust accumulated on the filter plate 2 is blown down by the airflow and enters the unidirectional dust collection cylinder 15 with the dust, the dust is adsorbed by the dust collection cotton 153, finally, the clean air pushes the exhaust turning plate 131 to rotate and is discharged out of the equipment, and the temperature and humidity of the air flow are monitored by the temperature and humidity tester 16 in real time.
