Description

Technical Field

[0001] The utility model relates to the technical field of environmental assessment monitoring, in particular to an air monitoring device for environmental assessment. Background Art

[0002] Air monitoring for environmental assessment is used to measure and evaluate pollutants present in the air, so that the air can be treated based on the measurement data.

[0003] Publication (Announcement) No.: CN218298171U, an air quality monitoring device, which uses a cleaning mechanism to clean the side of a filter mechanism away from an air inlet, and at the same time provides a back-blowing airflow to the air inlet through a back-blowing mechanism, and the back-blowing airflow can blow the dust swept by the cleaning mechanism away from the filter mechanism to prevent the dust from re-adhering to the filter mechanism;

[0004] In the above scheme, the cleaning mechanism and the back-blowing mechanism need to be realized by different power equipment, which consumes a lot of energy and has a complex structure. This scheme provides an air monitoring device for environmental assessment, which can use air flow as a power source to provide power for dust cleaning. Utility Model Content

In windy weather, air flows through the inner cavity in the middle of the cylindrical detector, which can drive the fan blade to rotate, and a cleaning plate is slidingly provided on the inner wall of the annular filter, and the cleaning plate is connected to the rotating shaft, which is suitable for the situation where the outdoor air flow is good.

[0007] Preferred technical solution one: a motor is fixed on the grid, and the rotating shaft is connected to the output shaft of the motor. The output shaft of the motor can actively drive the rotating shaft to rotate, thereby driving the fan blades to rotate and accelerate the flow of air in the middle cavity of the annular filter. It is suitable for situations where indoor air flow is poor.

[0008] Preferred technical solution two: a horizontal column is rotatably installed on the rear side of the grid, and the front end of the horizontal column is fixedly connected to the rear end shaft of the rotating shaft or the motor. Two groups of spiral grooves with opposite spiral directions are opened on the horizontal column, and the front and rear ends of the two groups of spiral grooves are connected to each other. The connecting rod fixed on the rear side of the cleaning plate slides through the rear end of the grid, and a connecting ring is fixed on the rear end of the grid. The connecting ring is rotatably and slidably sleeved on the horizontal column, and the protrusion fixed on the inner wall of the connecting ring slides along the spiral groove. The technical effect of driving the connecting ring to move back and forth is achieved through the continuous rotation of the horizontal column.

[0009] Preferred technical solution three: a vertical shaft is fixed on the bottom side of the cylindrical detector, and the vertical shaft is rotatably connected to the mounting seat. At the same time, a fixed bevel gear 1 is sleeved on the mounting seat, and a fixed bevel gear 2 is arranged at the rear end of the horizontal column. A transmission shaft is rotatably provided on a bracket fixed on the cylindrical detector, and a transmission bevel gear 1 and a transmission bevel gear 2 are respectively arranged at the upper and lower ends of the transmission shaft, and the transmission bevel gear 1 is meshed with the fixed bevel gear 2, and the transmission bevel gear 2 is meshed with the fixed bevel gear 1.

[0010] Preferred technical solution four: a reduction box is installed on the rear side of the grid, the front input shaft of the reduction box is fixedly connected to the rotating shaft or the rear end shaft of the motor, and the rear output shaft of the reduction box is fixed to the cross column.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. Depending on the use environment, choose whether to install a motor. The motor can accelerate the air flow when the air itself has poor fluidity, and draw air from a distance for detection;

[0013] 2. Based on the principle of self-service, the horizontal column is driven to rotate by the flowing detection airflow, and the cleaning plate automatically cleans the annular filter. During the cleaning, the flowing airflow will directly carry away the removed dust;

[0014] 3. The arrangement of the fixed bevel gear 1, the fixed bevel gear 2, the transmission bevel gear 1 and the transmission bevel gear 2 can simultaneously drive the cylindrical detector to rotate while the motor promotes the flow of air, thereby realizing air detection in multiple directions around.
