Description

Technical Field

[0001] The utility model belongs to the technical field of environmental detection, and in particular relates to a liftable air environment sampler. Background Art

[0002] With the development of urbanization, the problem of air quality has become increasingly prominent. In order to accurately understand the types, concentrations and distribution of pollutants in the air and take corresponding protective measures, it is necessary to test the air environment. Existing collection equipment is usually inconvenient to adjust the collection height, and the applicable scenarios are relatively limited.

[0003] A Chinese patent with publication number CN220770616U discloses an atmospheric collection device capable of collecting air at multiple heights. The solution includes a base plate, a placement plate, a fixed frame, a first motor, a second motor, a moving assembly and a rotating assembly. A circular plate is arranged inside the fixed frame. The above solution utilizes the first motor to drive the circular plate to move up and down to lift the main body of the atmospheric collection device, and utilizes the second motor to drive the circular plate to rotate so that the main body of the atmospheric collection device rotates, so that the main body of the atmospheric collection device can collect air at different heights and directions.

[0004] When the above scheme is used, in order to collect air in multiple directions at multiple specified heights, the first motor and the second motor need to be repeatedly turned on and off multiple times, and the number of times the motor switches are operated is large, and the sampling efficiency is low. Utility Model Content

[0012] The principle and effect of this technical solution:

[0013] The clutch mechanism is placed in the first working state, at which time the motor is connected to one of the screws through the clutch mechanism, and drives the screw to rotate, and then drives the other screw to rotate through the transmission belt. The two vertical rods move vertically as the screws rotate, and then drive the moving plate and the sampler body to move vertically.

[0014] Through the above arrangement, the purpose of driving the movable plate and the sampler body to move vertically is achieved.
