Gas detection device and gas sampling device thereof

Abstract

The invention discloses a gas detection device and a gas sampling device thereof, and relates to the technical field of gas detection, the gas detection device comprises a main body, a bottom plate is fixedly arranged at the bottom end in the main body, and a plurality of groups of lifting blocks are uniformly arranged at the edge position of the top of the bottom plate. Firstly, in the rotating process of a pressing rotating block, a telescopic rotating rod drives a clamping block to extend into a clamping groove of one lifting block, then the pressing rotating block is pressed, then the telescopic rotating rod drives a first toothed plate to ascend, and the telescopic rotating rod ascends and drives the lifting blocks and a vacuum sampling pipe to ascend through the clamping block at the same time; wherein the first toothed plate ascends to drive the second toothed plate and the ejector rod to descend through the gear, and the vacuum sampling pipe ascends and extends out of the upper part of the main body for a certain distance while the ejector rod descends, so that the ejector rod and the ejector pin extrude each other, the vacuum sampling pipe is opened for gas sampling, and the unsampled vacuum sampling pipe can be conveniently and quickly replaced; and the gas sampling process is more thorough.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas detection device and a gas sampling device thereof. Background technique [0002] Gas detection mainly uses gas sensors to detect the types of gases existing in the environment. Gas sensors are sensors used to detect the composition and content of gases. In urban management, staff are required to perform air gas detection in urban areas to obtain urban Air quality detection data, where gas detectors are usually used for gas detection. [0003] A gas detector is an instrumentation tool for gas leakage concentration detection, including portable gas detectors, hand-held gas detectors, fixed gas detectors, online gas detectors, etc., mainly using gas sensors to detect The types of gases that exist, gas sensors are sensors used to detect the composition and content of gases, and gas sampling is the process of collecting pollutant samples or polluted air samples in the at...

Problems solved by technology

[0005] Based on this, the object of the present invention is to provide a gas detection device and a gas sampling device thereof, to solve the problem of the overall inconvenient portability of the staff in the prior art, the inability to better collect gas in a narrow space and the need to replace different vacuums. The opening and closing of the sampling tube is mostly controlled by electronic control equipment, which has a certain degree of energy consumption.
