[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described here are only used to explain the utility model and are not used to limit the utility model.

The lock buckle 11 cooperates with the lock sleeve 21. By buckling the lock buckle 11 on the lock sleeve 21, the box cover 2 can cover the opening of the box body 1 and lock it. By removing the lock buckle 11 from the lock sleeve 21, the box cover 2 can be opened. At a position close to the opening of the box body 1, the box body 1 is also fixedly installed with one side of a first fixing plate 51, and the other side of the first fixing plate 51 is hingedly connected to one side of a cover plate 5 through a hinge. The other side of the cover plate 5 cooperates with one side of a second fixing plate 55 through a knob 54, and the other side of the second fixing plate 55 is fixedly installed on the box body 1. One end of a connecting column 56 is fixedly mounted on the knob 54, and the connecting column 56 is rotatably matched with the cover plate 5. A limit plate 57 is fixedly mounted on the other end of the connecting column 56. When the knob 54 is in the Figure 5 When the knob 54 is in the position shown, the limit plate 57 will prevent the cover 5 from opening. When the knob 54 is rotated 90°, the limit plate 57 will also rotate and retract. Figure 2 When the knob 54 is in a state parallel to the side wall of the box body 1, the cover 5 is in an open state. A controller 53 is also fixedly installed in the middle of the cover 5 to control the monitoring mechanism at the bottom.

[0024] The monitoring mechanism includes a sampling probe 3, which is fixedly mounted on the box 1; a particle detector 32 is installed directly below the sampling probe 3, and the particle detector 32 is connected to the sampling probe 3 through a vertical first air pipe 31, and the particle detector 32 is connected to an air pump 35 through an air path, and one end of an air outlet pipe 36 is also installed on the air pump 35, and the other end of the air outlet pipe 36 passes through the box 1; the air pump 35, the controller 53, and the particle detector 32 are all electrically connected to a power module 38, and the power module 38, the particle detector 32, and the air pump 35 are all fixedly mounted on the box 1, and the controller 53 is electrically connected to the air pump 35 and the particle detector 32. Among them, the particle detector 32, the air pump 35, and the power module 38 are all fixedly mounted on the box 1.

[0025] As a further illustration of this example, a flow controller 52 is also fixedly mounted on the cover plate 5, one end of the second air pipe 33 is connected to the particle detector 32, and the other end passes through the cover plate 5 upward to communicate with the air inlet of the flow controller 52, and a third air pipe 34 is connected to the air outlet of the flow controller 52, and the third air pipe 34 passes through the cover plate 5 and is downwardly connected to the air pump 35. An adjusting knob is provided on the flow controller 52, and the size of the gas channel is changed by twisting the adjusting knob, thereby adjusting the flow, which is similar to the switch of an old-fashioned faucet.

[0026] As a further illustration of this example, a protective cover 39 is fixedly installed on the outside of the sampling probe 3. A gap is provided between the protective cover 39 and the sampling probe 3. Air is sucked in from the bottom along the gap, thereby preventing debris or moisture from entering the trachea and affecting the monitoring of particulate matter.

[0027] As a further illustration of this example, an opening is provided on one side of the box body 1 where the lock buckle 11 is installed, and a heat dissipation fan 12 is installed on the opening, and the heat dissipation fan 12 is electrically connected to the power module 38. The heat dissipation fan 12 can discharge the heat generated by the monitoring mechanism during operation, thereby preventing damage to the equipment due to excessive temperature in the box body 1.

[0028] As a further illustration of this example, a wireless communication module 37 is also fixedly installed inside the box 1, and the wireless communication module 37 is electrically connected to the controller 53 and the power module 38. The controller 53 sends the data detected by the particle detector 32 to the inspector's device through the wireless communication module 37, thereby realizing remote monitoring.

[0029] As a further illustration of this example, an ultrasonic wind force and direction detector 4 is also fixedly installed on the top of the box body 1, and a noise detector 41 is fixedly installed on the ultrasonic wind force and direction detector 4. The ultrasonic wind force and direction detector 4 and the noise detector 41 are both electrically connected to the power module 38 and the controller 53, so as to facilitate the detection of wind and noise.

[0030] By controlling the controller 53 to control the power module 38 to power the air pump 35, air will flow in from the sampling probe 3, directly enter the particle detector 32 through the first air pipe 31, and when the airflow is stable, that is, when the data of the particle detector 32 is stable, the reading is taken, and the gas is discharged to the outside of the box 1 through the air outlet pipe 36. When detecting the air, the power module 38 will also power the ultrasonic wind force and direction detector 4, the noise detector 41 and the cooling fan 12, so that they can operate synchronously.

[0031] In summary, the difference between the online monitoring device for air particles provided by the utility model and the prior art is that the utility model installs the particle detector 32 just below the sampling probe 3 and connects it through the vertical first air pipe 31, so that the air flow is more stable, the deposition of particles is avoided, and the measurement error is reduced. By connecting the particle detector 32 to the controller 53, the controller 53 transmits the data to the inspector's device through the wireless communication module 37, so that the user can obtain the data of the sensor at any time, so as to facilitate the monitoring of the particle content in the air. In addition, the setting of the ultrasonic wind force and direction detector 4 and the noise detector 41 also facilitates the monitoring of local wind and noise.
