Description

Technical Field

[0001] This invention relates to the field of monitoring devices, and more particularly to an atmospheric composition monitoring device and its usage method. Background Technology

[0002] In atmospheric monitoring, a common method is to use sensors to monitor the content of various components in the air. For example, patent application number 201720570859.5 discloses an atmospheric monitoring box and an atmospheric monitoring system, relating to the field of atmospheric monitoring equipment. The atmospheric monitoring system includes a power supply box, a support platform, and an atmospheric monitoring box. The atmospheric monitoring box includes a shell, an atmospheric sampling device, an analysis device, and a display device. The analysis device is located inside the shell and electrically connected to the display device, which is located on the outer surface of the shell. The atmospheric sampling device includes a sampling body, a temperature sensor, a humidity sensor, and a particulate matter detector. The sampling body is fixedly connected to one side of the shell and has a sampling channel that passes through the sampling body and communicates with the outside. Compared with the prior art, the atmospheric monitoring box provided by this utility model can collect accurate data even in rainy or dusty weather, greatly improving the reliability of the data collected by the atmospheric monitoring box.

[0003] However, the aforementioned patents still cannot completely eliminate the impact of rainwater and dust, because rainwater and dust can still enter the sampling channel 132 through the airflow fan 139 and come into contact with the sensor, thereby affecting the accuracy of the collected data, and improvements are needed.

This effectively prevents rainwater from interfering with sensor readings. Furthermore, the air drawn in by the fan flows through the first and second air ducts into the water inside the bend. The water accumulated in the bend filters out some of the dust in the air before the air comes into contact with the sensor, effectively preventing dust in the air from affecting the sensor.

Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0023] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1-5 As shown, an atmospheric composition monitoring device includes a housing 1 made of stainless steel. A fan 11 is installed on the top of the housing 1 and welded to the housing 1. The air outlet of the fan 11 is fixedly connected to the upper end of the air outlet pipe 10, which passes through the top of the housing 1. The lower end of the air outlet pipe 10 is fixedly connected to the upper end of the first air guide pipe 2, which is located inside the water supply pipe 3. The upper end of the water supply pipe 3 is fixedly connected to the top of the housing 1. The lower end of the water supply pipe 3 is fixedly connected to the left end of the bend pipe 4, which is U-shaped. The right end of the bend pipe 4 is fixedly connected to the upper end of the drain pipe 5. A sensor 6 is installed inside the drain pipe 5 and is detachably connected to the bend pipe 4. A drainage mechanism is installed inside the bend pipe 4. The lower end of the first air guide pipe 2 is fixedly connected to the upper end of the second air guide pipe 9, which extends to the bottom of the bend pipe 4. The water supply pipe 3, the bend pipe 4, and the drain pipe 5 are all made of plastic.

[0026] The drainage mechanism includes a base 16, which is fixed to the lower end of the bend 4. A lower guide pipe 20 is fixedly installed through the base 16 and located in the center of the base 16. An upper guide pipe 13 is installed above the lower guide pipe 20 and is fixedly installed through the upper end of the bend 4. Both the upper guide pipe 13 and the lower guide pipe 20 are fitted onto the drain pipe 17, which is slidably connected to the upper guide pipe 13 and the lower guide pipe 20. A float 14, made of wood, is fixedly fitted onto the drain pipe 17. Block 14 is located inside the bend 4. Several drainage holes 19 are opened at the lower part of the drain pipe 17. The upper and lower ends of the drain pipe 17 are respectively fixed with an upper limit block 12 and a lower limit block 18. Both the upper limit block 12 and the lower limit block 18 are disc-shaped. A limit plate 21 is provided above the base 16. The limit plate 21 is fixedly sleeved on the drain pipe 17. A spring 15 is sleeved on the drain pipe 17. The spring 15 is located between the float 14 and the base 16. The upper end of the spring 15 is fixedly connected to the float 14, and the lower end of the spring 15 is fixedly connected to the limit plate 21.

[0027] A water tank 8 is provided below the drain pipe 17. The top of the water tank 8 is open. The water tank 8 is fixedly connected to the bottom of the shell 1. The bottom of the water tank 8 is fixedly connected to the upper end of the second drain pipe 22. The lower end of the second drain pipe 22 passes through the bottom of the shell 1 and extends to the bottom of the shell 1. Multiple support pipes 7 are fixedly provided on the bottom surface of the shell 1.

[0028] The support tube 7 is internally threaded with a support block 23. A caster wheel 24 is installed at the bottom of the support block 23. A sealing disc 25 is located below the caster wheel 24. The sealing disc 25 is threadedly connected to the inner wall of the support tube 7. The center of the bottom surface of the sealing disc 25 is fixed to a knob 26. The sealing disc 25 can be easily rotated and removed by setting the knob 26.

[0029] Working principle: When in use, the fan 11 is turned on, drawing in air from outside the housing 1. The air then flows sequentially through the outlet pipe 10, the first guide pipe 2, and the second guide pipe 9 before being discharged into the bend 4. When it rains, rainwater flows through the fan 11, outlet pipe 10, first guide pipe 2, and second guide pipe 9 into the bend 4 and accumulates there, preventing it from flowing into the drain pipe 5 and affecting the sensor 6. As rainwater accumulates in the bend 4, the air discharged through the second guide pipe 9 is first discharged into the rainwater, where it filters out some of the large dust and impurities before flowing into the drain pipe 5 and contacting the sensor 6. Through sensor 6 atmospheric components .

[0030] When a large amount of rainwater accumulates in the bend 4, the rainwater causes the float 14 to rise. The float 14 then causes the drain pipe 17 to slide upward along the upper guide pipe 13 and the lower guide pipe 20, allowing the drain hole 19 at the top to enter the bend 4. The water in the bend 4 then enters the drain pipe 17 through the drain hole 19 at the top and is discharged through the drain hole 19 at the bottom, causing the water level in the bend 4 to drop. The float 14 and the drain pipe 17 descend synchronously. When the drain hole 19 at the top moves out of the bend 4, the drainage stops.

[0031] The water discharged from drain pipe 17 flows into water tank 8 and then is discharged through second drain pipe 22.

[0032] When it is necessary to move this device, rotate the knob 26 to drive the sealing disc 25 to rotate synchronously, thereby removing the sealing disc 25. Then, grasp the part where the universal wheel 24 is fixed to the support block 23 and rotate it to drive the support block 23 to rotate and move the support block 23 down, so that the universal wheel 24 moves to below the support tube 7. Then push this device to drive it to move using the universal wheel 24.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
