Abstract

The invention discloses a height-adjustable outdoor air sampling device, relates to the field of environment detection, and mainly solves the problem that when outdoor air is sampled, after different heights need to be adjusted, an air extracting pump is used for extracting air and sampling, and waste is caused due to the fact that a large number of electric equipment is used. The device comprises a sampling column, a rotating mechanism, a fixing mechanism, a control mechanism and a sampling mechanism are arranged on one side of the sampling column, a first lifting line is retracted through rotation of a servo motor, a sampling barrel is driven to ascend, the height is adjusted, and air is extracted and sampled through movement of a stretching rod. The air sampling device has the beneficial effects that the height adjustment and air sampling processes can be completed through one motor arranged in the sampling mechanism, the sampling cost is reduced, the consumption is reduced, the height can be adjusted for sampling, and a plurality of sampling spaces are arranged in the sampling cylinder, so that more samples can be conveniently taken, and the detection result is more accurate.

Description

technical field [0001] The invention relates to the field of environment detection, in particular to a height-adjustable outdoor air sampling device. Background technique [0002] Everyone needs to breathe air, and the quality of the air is closely related to everyone's health. In order to ensure people's health, it is necessary to ensure the quality of the air, so that the outdoor air needs to be tested, and the air quality at different heights is different. air for sampling. [0003] In the prior art, for example, the patent number is CN201610510116, and the patent name is a patent for an air sampling device, which mainly includes the sampling machine body, air pump, first air extraction pipe, second air extraction pipe, third air extraction pipe, and dust particle filter. The device and the air storage tank sample the air at different heights through the different lengths of the first air extraction pipe, the second air extraction pipe, and the third air extraction pipe....
