Air quality detection device and method thereof

Abstract

The invention relates to the technical field of air quality detection devices, in particular to an air quality detection device and a method thereof. The air quality detection device comprises a base and an air detection device, a lower telescopic rod is installed at the upper end of the base, an upper telescopic rod is installed at the upper end of the lower telescopic rod, an air inlet control device is installed at the upper end of the upper telescopic rod, and a buffer plate is installed on the outer side of the upper end of the air inlet control device; the air detection device is arranged on the outer side of the lower telescopic rod, and the cavity is formed in the middle of the lower end of the air inlet control device, so that the air detection device can be in contact with external air to keep real-time monitoring when the air velocity is normal, after the flow speed of external air is increased, the air inlet control device moves downwards to cover the air detection device, and the two sides of the deceleration channel are arranged in a continuous bending shape, so that the intermittently entering airflow can be in contact with the air detection device only after being fully blocked by the two sides of the deceleration channel, and the effects of reducing the flow speed of the air and improving the detection precision are achieved.

Description

technical field [0001] The invention relates to the technical field of air quality detection devices, in particular to an air quality detection device and a method thereof. Background technique [0002] The problem of air quality has become a very important indicator after the implementation of China's environmental protection policy. Therefore, real-time detection and monitoring of air quality in various environments is required. Generally, multiple air monitoring points will be set up in a city, especially In the construction project implementation site, the installed air PM2.5 concentration monitoring instrument can achieve timely alarm and stop the high-pollution construction behavior. [0003] However, most of the existing air quality detection devices lack the structure to control the flow rate of the external air, so that when a large air flow from the outside comes into contact with the air quality detection device, it will instantly increase the concentration of PM2...

Problems solved by technology

[0003] However, most of the existing air quality detection devices lack the structure to control the flow rate of the external air, so that when a large air flow from the outside comes into contact with the air quality detection device, it will instantly increase the concentration of PM2.5 particles detected by it, resulting in The accuracy of monitoring is reduced, and the existing quality control and inspection devices cannot protect some flying rocks produced on the construction site, resulting in easy damage to the equipment
