Sampling probes, automatic sampling devices and container inspection systems

Abstract

Provided are a sampling probe, an automatic sampling device including the sampling probe and a container detection system. The sampling probe includes: a mounting base; a housing mounted on the mounting base, the housing defines a first accommodating chamber, the accommodating chamber has an opening, and an opening is formed on the housing to communicate with the first accommodating chamber and the shell. Exhaust holes on the outside of the body; joints, formed on the outer edge of the opening of the first accommodation chamber and formed to be sealed and combined with the air outlet of the outer box of the container; and suction devices, installed on the on the casing, and is configured to suck the air in the container into the first accommodation chamber through the air outlet. The sampling probe can collect the smell of toxic and harmful gases / hazardous chemicals inside the container at the air outlet of the container without damaging the overall structure of the container.

Description

technical field [0001] Embodiments of the present disclosure relate to a detection system suitable for detecting a specific gas in a container, and more particularly, to a sampling probe suitable for detecting a specific gas in a container, an automatic sampling device including the sampling probe, and a container detection system. Background technique [0002] Radiation imaging technology has been widely used in the safety detection of large containers, especially for the detection of high-density substances in containers that have obvious attenuation of ray intensity. However, radiation imaging technology is difficult to detect and identify low atomic number and low density substances such as toxic and harmful gases, fumigants, high-flammable gases, trace drugs, and explosives in containers. On the other hand, photoionization, Fourier transform infrared spectroscopy, microbalance, surface acoustic wave, and gas chromatography-ion mobility spectrometry are very suitable for...

Problems solved by technology

However, on the one hand, because the container body is relatively sealed, volatile samples can only diffuse out from the container door cracks and the container ventilator, and the volatilization amount is limited; / Hazardous chemical samples will be diluted rapidly after being combined with the air outside the container. The collected samples are difficult to represent the actual situation of the samples in the container, the detection error is high, and it is easy to cause false positives

[0004] In addition, a container gas detection device has also been developed. When detecting toxic and harmful gases / hazardous chemicals in the container, the operator must hold the sampling probe and insert the sampling probe through the container door to inhale and sample. On the one hand, the sampling It is cumbersome and cannot be intelligentized, and may cause harm to the operator; on the other hand, forcibly sampling at the container door gap may damage the sampling probe or the waterproof performance of the container
