Description

Technical Field

[0001] The utility model relates to the technical field of air quality detection, in particular to an intelligent air quality inspection device. Background Art

[0002] By using dust concentration sensors to conduct air quality testing in a mobile patrol manner, pollution problems can be discovered and resolved in a timely manner, and targeted testing of ambient air quality in different areas and time periods can be performed.

[0003] In the Chinese utility model patent with publication number CN219328710U, an intelligent air quality inspection device is disclosed. The rotation of the screw rod drives the entire slide plate to move left and right, thereby driving the movement of the entire inspection box, starting the air pump and the dust concentration sensor. The air pump draws air from the production workshop, and the air enters the dust concentration sensor through the air intake hood and the air intake pipe for detection. When the dust concentration in the air exceeds the standard, the dust concentration sensor activates the sound and light alarm through the controller to sound an alarm to prompt the staff to deal with it in time.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] A lead screw is used to drive the inspection box to move back and forth for inspection. Although it has a simple structure and is easy to operate, it is necessary to adaptively select a lead screw of corresponding length during long-distance transmission. During long-distance transmission, the rigidity of the lead screw is reduced due to the long distance, which makes the weight or torque borne by the lead screw uneven, further causing the lead screw to bend, thereby affecting the stability of the long-distance movement of the inspection box. In addition, an overly long lead screw occupies too much space during storage and transportation, which reduces the convenience of storage and transportation. At the same time, when conducting air quality inspections on workshop areas of different lengths, it is necessary to adapt to the selection of lead screws of different lengths for installation, resulting in a reserve of multiple different types of lead screws, which increases the cost of quality inspections while reducing the flexibility of using the air quality inspection device.
