Description

Comprehensive sampling device for ambient air Technical Field The utility model relates to the technical field of environmental monitoring, in particular to an environment air comprehensive sampling device. Background The comprehensive atmospheric particulate sampler is precise equipment for collecting suspended particulate matters (such as PM 2.5、PM10 and TSP) and gaseous pollutants in air, has the core functions of collecting the particulate matters with different particle diameters on a filter membrane through a multi-stage gas circuit separation technology, supporting synchronous collection of the gaseous pollutants (such as SO 2、NOX and VOCs), providing reliable data for air quality assessment and pollution source analysis, and is widely applied to the fields of environmental monitoring, industrial emission detection and scientific research. The comprehensive atmospheric particulate sampler mainly comprises a sampling host and a divider, and is generally provided with a tripod for conveniently erecting equipment in field operation, the tripod is supported after the sampling host reaches a sampling position, and then the sampling host is mounted on the top of the tripod, but the sampling is generally carried out in a plurality of sampling positions in the field, so that the tripod and the sampling host are required to be frequently assembled and disassembled, and are also required to be separated in carrying, the operation is troublesome, and the detection effect is affected. In order to solve the above problems, an ideal technical solution is always sought. Disclosure of Invention The utility model aims at overcoming the defects of the prior art, thereby providing an environment air comprehensive sampling device which is convenient to transfer between different sampling points in the field. In order to achieve the purpose, the technical scheme includes that the comprehensive sampling device for the ambient air comprises a sampling host, a divider, a folding support and a handle arranged on the sampling host, wherein the folding support comprises a bearing base and three folding support legs, the sampling host is arranged on the top of the bearing base, each folding support leg comprises a first connecting rod, a middle connecting rod and a last telescopic rod, the tops of the three first connecting rods are respectively connected to the middle of the front section of the bottom of the bearing base and the two sides of the rear section of the bottom of the bearing base, two ends of the middle connecting rod are respectively hinged with the bottom end of the first connecting rod and the starting end of the last telescopic rod through a hinge mechanism, each hinge mechanism is provided with a rotation angle locking mechanism, and the folding support legs can achieve a straight state or achieve a state that the middle connecting rod is horizontal, the last telescopic rod is vertically upwards and is arranged around the sampling host through rotation of the hinge mechanism. The folding support leg has the advantages that when the folding support legs are unfolded and the length of each tail telescopic rod is adjusted during field operation, the support of the sampling host can be achieved, when the folding support leg is transferred, the three folding support legs are folded, the three tail telescopic rods are arranged around the sampling host in a surrounding mode, the size of equipment is effectively reduced, workers can conveniently carry the handles to transfer the equipment, meanwhile, in the folded state, the three middle connecting rods are horizontally arranged to form a platform, and the platform can be directly placed on the ground for sampling under a proper scene, and therefore operation scenes are widened.
