Centralized detection device for air collection sample

Abstract

The invention discloses a centralized detection device for an air collection sample. The centralized detection device comprises a supporting plate, a corner driving mechanism, a circular groove, an L-shaped seat, an electric telescopic rod, an air cylinder, a puncture needle, a pressing ring, a vacuumizing pump and an air detector; the corner driving mechanism is arranged on the upper end face ofthe supporting plate, a driving end of the corner driving mechanism is connected with the center of the bottom of the circular groove, and a plurality of gas collecting bottle clamping mechanisms areannularly arrayed on the bottom face of an inner cavity of the circular groove; the electric telescopic rod is arranged on the supporting plate through the L-shaped seat, the axial direction of the electric telescopic rod is perpendicular to the supporting plate, the telescopic end of the electric telescopic rod faces the supporting plate, the telescopic end of the electric telescopic rod is provided with an installation plate and an air cylinder is disposed on the lower end face of the installation plate, and the telescopic end of the air cylinder is vertically downward and provided with thepuncture needle. The vacuumizing pump and the air detector are arranged on the upper end face of the supporting plate, an air suction end pipeline of the vacuumizing pump is communicated with the puncture needle inner cavity, and an air outlet end pipeline of the vacuumizing pump is communicated with the air detector. The device is convenient to use, and the working intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of air detection, in particular to a centralized detection device for collecting air samples. Background technique [0002] As the public pays more attention to data such as environmental quality and meteorological conditions, the industry has also begun to devote itself to the development of relevant software and hardware, in order to provide real-time data on environmental quality and meteorological conditions that clients are concerned about. In addition, due to the development of modern technology , the cost of data storage has been greatly reduced, and technologies such as cloud computing and big data analysis have become more mature, and the demand for obtaining a large amount of raw data has begun to increase. [0003] At present, the air collection samples are stored in the gas collection cylinders, and then the air samples in each gas collection cylinder are detected by an air detector. This process...

AI Technical Summary

Problems solved by technology

[0003] At present, the air collection samples are stored in the gas-collecting cylinders, and then the air samples in each gas-collecting cylinder are detected by an air detector. This process requires manual use of vacuum equipment to pump the gas in each gas-collecting cylinder. To the air detector for detection, this process needs to be manually held one by one, and then the puncture needle at the suction end of the vacuum equipment is pierced through the stopper of the gas bottle, and then the air in the gas bottle is extracted to the air detector In the process, the operation is cumbersome, so the labor intensity of the staff is high
