Description

Technical Field

[0001] This utility model relates to the field of air environment monitoring technology, specifically to a sampling device for air environment monitoring. Background Technology

[0002] Environmental monitoring is a discipline that uses modern technologies such as chemistry, physics, biology, medicine, telemetry, remote sensing, and computers to monitor, measure, and control various indicator data reflecting environmental quality and its changing trends, thereby making a comprehensive evaluation of environmental quality. Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. It involves monitoring and measuring indicators reflecting environmental quality to determine the level of environmental pollution and the degree of environmental quality. Air sampling is typically required during environmental monitoring to facilitate air quality testing by staff.

[0003] Chinese Patent Publication No. CN211317909U, authorized on August 21, 2020, discloses an air sampling device for environmental monitoring. The device includes a sampling device housing. A cover is bolted to the upper end of the housing, and a ventilation pipe is threaded to the lower end of the cover. A rotating pipe is rotatably connected inside the ventilation pipe. A collecting pipe is fixedly connected to the upper end of the rotating pipe, and a first gear is fixedly sleeved on the outer side of the rotating pipe. The lower end of the first gear contacts the upper end of the cover. This air sampling device uses a motor to drive the rotating pipe and collecting pipe to rotate, allowing the collecting pipe to collect air from different directions, resulting in more uniform air collection and avoiding the limitation of collecting air only from one direction. Furthermore, a splicing frame is designed using a connecting pipe and a base to support the sampling device. The connecting pipe can be stored on the base, which can be installed at the bottom of the sampling device for easy portability.
