Abstract

The invention discloses a support for atmospheric pollution prevention and control sampling and a using method, and belongs to the technical field of atmospheric sampling auxiliary equipment. The support for atmospheric pollution prevention and control sampling comprises a workbench, and a protection framework is fixedly connected to the bottom end of the workbench. According to the support for atmospheric pollution prevention and control sampling and the using method, a swing connecting plate is arranged, in the protection frame, an adjusting knob rotates to drive a threaded sliding block to slide along the inner wall of the protection frame through a working threaded rod, the threaded sliding block drives the swing connecting plate integrally connected with a swing plate to rotate through a sliding hole plate, the swing connecting plate rotates to drive two sets of movable sliding blocks to move through swing sliding grooves, the two sets of movable sliding blocks can synchronously move, the phenomenon of water leakage caused by untight opening and closing of waterproof umbrella cloth is reduced, the movable sliding blocks drive the two sets of waterproof umbrella cloth connected with the swing hole plate to relatively rotate by 90 degrees through the movable sliding grooves to close the workbench, and waterproof operation on the workbench is achieved.

Description

technical field [0001] The invention relates to the technical field of air sampling, in particular to a support for air pollution prevention and sampling and a use method. Background technique [0002] Atmospheric pollutants enter the atmosphere from man-made sources or natural sources, participate in the circulation process of the atmosphere, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities and physical deposition in the atmosphere. When the concentration increases to a certain level, it will directly or indirectly cause acute and chronic harm to people, organisms or materials. If it is polluted, the atmosphere needs to be sampled. Atmospheric sampling refers to the method of collecting pollutant samples or polluted air samples in the atmosphere. One type of collection method is to pass a large amount of air through a liquid absorbent or a solid absorbent Pollutants with a lower concentration are enriched...
