Description

Technical Field

[0001] The utility model mainly relates to the technical field of explosion-proof air samplers, and in particular to an explosion-proof air sampler. Background Art

[0002] An explosion-proof atmospheric sampler is an instrument used to collect air samples and detect combustible gases, oxygen and other components in them. The background of this technology can be traced back to the early mine safety detection technology, when mine safety detection mainly relied on manual inspection and simple instruments and equipment. With the continuous development of science and technology, the technology of explosion-proof atmospheric samplers has also been continuously improved and perfected.

[0003] For example, an explosion-proof atmospheric sampler provided by Chinese patent publication number CN207036514U includes a main body, two collecting heads are provided on the left side of the main body, the two collecting heads are arranged side by side at the two ends of the left side of the main body, and a drainage mechanism is also provided on the main body, the drainage mechanism includes a guide shell, a guide cover and a guide unit, the guide shell is arranged on the right side of the main body, the guide cover is arranged on the side of the guide shell away from the main body, there are two guide units, the two guide units are respectively arranged on the upper and lower sides of the main body, and the guide unit includes a guide tube, a motor, a gear set, a transmission rod and a plurality of fan blades arranged on the transmission rod.

[0004] The above application can assist the collection head in collecting the atmosphere by setting up an external drainage mechanism with airflow guiding function, so that the external interference will be relatively small, so that the sampling progress can be better controlled, and the sampling data can be more accurate. Although the drainage mechanism of the above application conducts airflow through the guide tube and the fan blade, the guide tube and the collection head are at the same angle, and can only collect gas in a single direction. The collection range is small, the sampling is limited, and the accuracy of the sampled data is not ideal. Utility Model Content

[0015] The utility model stores the bellows in the placement groove of the mounting block. When a larger range or multi-angle sampling is required, the bellows is taken out and installed on the connecting pipe, and then the angle of the bellows is adjusted to perform sampling. The explosion-proof atmospheric sampler of the utility model can sample gas from different angles and directions, thereby avoiding the limitation of a single sampling point and improving the accuracy and representativeness of sampling. Through multi-angle sampling, the sampling error can be reduced, and the reliability and accuracy of sampling can be improved. The explosion-proof atmospheric sampler can sample gas from different heights, different positions, and different directions, and is suitable for a variety of different environments and occasions.

[0016] After the utility model adjusts the bellows, the adjustment plate is pulled out, and the angle of the mounting plate can be adjusted by the hinge, and then the bellows is fixed by the elastic hoop, so as to fix and support the bellows. The utility model can improve the stability of the bellows by setting the supporting mechanism, reduce the deformation and distortion of the bellows, keep the bellows in a good shape, and ensure the reliability of the connection.
