High-precision atmosphere sampler

Abstract

The invention relates to the technical field of air samplers, in particular to a high-precision air sampler which comprises a storage box body, an upper cover plate is connected to the left side of the top end of the storage box body through a rotating shaft, a movable blade is connected to the right side of the upper cover plate through a rotating shaft, a limiting ring is fixedly connected to the right end of the storage box body, and the limiting ring penetrates through the movable blade, a sampler main body is placed in the storage box body, a transmission mechanism is arranged in the storage box body, and the transmission mechanism comprises a first chamber. According to the invention, an operator can quickly and conveniently place and take the sampler main body, and can open and close an upper cover plate to control left and right movement of two groups of clamping plates so as to control clamping and clamping release of the sampler main body, so that the operator can quickly and conveniently place and take the sampler main body, meanwhile, the stability of the sampler main body can be ensured during transportation, and the practicability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of atmospheric samplers, in particular to a high-precision atmospheric sampler. Background technique [0002] In order to better detect the atmospheric environment, the air is generally sampled by an atmospheric sampler, and the sampled gas is analyzed to understand the degree of pollution of the environment by harmful gases, and the actual situation of the pollution is provided to the relevant competent departments to take Countermeasures, so as to ensure people have a healthy living environment, it has the characteristics of small size, convenient use, high suction negative pressure, stable flow rate and long running time. [0003] However, a high-precision atmospheric sampler currently on the market has the following problems during use: a. Since the operator needs to perform atmospheric sampling in different outdoor environments, the operator needs to put the atmospheric sampler inside the box For trans...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a high-precision atmospheric sampler, which can solve the problems that it is inconvenient for the operator to store and take the atmospheric sampler in the above background technology, and it is inconvenient to carry the outdoor sampling as a whole.
