Problems solved by technology

[0003] Before air detection, it is usually necessary to detect the air through a gas collection device, but most of the existing gas collection devices are stored through the sample air bag, the storage capacity is small, and it is easy to expand and rupture due to the extrusion of foreign objects during transportation. And after the sample airbag is used for a long time, various bacterial impurities will adhere to its inner wall, which will seriously interfere with the detection accuracy of the gas collected later, resulting in inaccurate detection data. Therefore, the present invention proposes a gas sampling method for environmental detection. device to solve the above problems

Embodiment 1

[0020] see figure 1 , in an embodiment of the present invention, a gas sampling device for environmental detection, comprising a base 1, a lifting assembly, a bearing platform 8 and a sampling cylinder 20, the bearing platform 8 is arranged above the base 1, and the lifting assembly is arranged on the base 1 and the bearing Between the platforms 8, the sampling cylinder 20 is arranged above the carrying platform 8 through a plurality of telescopic rods 23. The telescopic rods 23 are electric telescopic rods. The assembly can flexibly adjust the collection height of the sampling cylinder 20. The lifting assembly includes two internally threaded pipes 26, both of which are rotatably mounted on the base 1 through bearings. The two internally threaded pipes 26 are threadedly connected to A threaded rod 7, the upper ends of the two first threaded rods 7 are fixedly connected to the bottom of the bearing platform 8, and one of the two internally threaded pipes 26 is provided with a ...

Embodiment 2

[0026] see figure 2 The difference between the embodiment of the present invention and embodiment 1 is that, further, in order to facilitate the movement of the device, a plurality of rollers 31 are symmetrically arranged at the bottom of the base 1, and the rollers 31 are self-locking rollers, and the collectors pass through a plurality of Roller 31 can move this device easily and conveniently, saves time and effort, is convenient and practical.

[0027]The working principle of the present invention is: when the present invention is in use, first move the device to the collection point, then adjust the lifting assembly according to the collection height required, then unscrew the sealing cover 22 and start the second servo motor 24, the second servo motor 24. The second belt transmission mechanism 9 drives the two second threaded rods 25 to rotate, and the rotation of the two second threaded rods 25 drives the mounting plate 11 to move toward the direction of the sampling cy...

Abstract

The invention discloses a gas sampling device for environmental detection. The gas sampling device comprises a base, a lifting assembly, a bearing table and a sampling cylinder, wherein the bearing table is arranged above the base; the lifting assembly is arranged between the base and the bearing table; the sampling cylinder is arranged above the bearing platform through using a plurality of telescopic rods; two strip-shaped plates are fixedly mounted on the bearing table; two second threaded rods are rotationally mounted between the two strip-shaped plates in a front-back symmetry manner; a mounting plate is arranged between the two second threaded rods in a threaded penetrating manner; and a push rod is fixedly mounted on the mounting plate, and a rotating pipe for cleaning the samplingcylinder is rotationally mounted on the mounting plate through a bearing. The gas sampling device is reasonable in structural layout, large in collection amount, can guarantee safety of gas samples inthe gas sample transportation process, has a sampling barrel cleaning function, can clean the sampling barrel after one-time collection is completed, avoids interference of substances remaining in the sampling barrel on detection of gas collected next time to affect detection precision, and is simple in operation, convenient to use and quite practical.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a gas sampling device for environmental detection. Background technique [0002] With the continuous progress of human civilization, the disadvantages of social development are gradually manifested, which has caused almost irreversible damage to the earth we depend on for survival, especially in terms of air quality, the damage is particularly obvious. Nowadays, there is a certain degree of air quality testing. Standards, air detection in a broad sense, refers to the detection of air components, and air detection in a narrow sense, mainly from the perspective of application, focusing on indoor air detection. A series of standards have been formulated for air detection, namely Air testing standards. [0003] Before air detection, it is usually necessary to detect the air through a gas collection device, but most of the existing gas collection devices are stored th...
