Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring and data collection technology, specifically a sampling device for environmental monitoring. Background Technology

[0002] With the rapid development of national industry, the amount of pollutants in the ambient air caused by industrial production is becoming increasingly serious, necessitating regular testing of the ambient air, and therefore requiring the use of air sampling devices.

[0003] A search revealed that the prior art, under publication number CN217930995U, discloses an air sampling device for environmental monitoring. This device includes a support plate, a support column fixedly mounted at the rear upper part of the support plate, a baffle fixedly mounted at the front upper part of the support column, a groove in the middle of the support column, a threaded rod movably mounted in the middle of the groove, and a movable block movably mounted on the middle outer side of the threaded rod. A sampler is mounted at the front end of the movable block. Through the designed support column, baffle, groove, threaded rod, drive motor, and movable block, the support column is mounted at the rear upper part of the support plate, the groove is located in the middle of the support column, the baffle is mounted at the upper end of the support column, and the threaded rod is mounted in the middle of the groove. When the drive motor is activated, it rotates the threaded rod, causing the movable block and sampler to move upwards. This allows the sampler to rise and detect air at a higher altitude. Furthermore, the sampler's operation at a higher altitude prevents damage from passersby or children, thus protecting the sampling device.

[0004] However, while the air sampling device of this utility model is height-adjustable to prevent damage from the elderly and children, dust and impurities enter and exit the air sampling device. These dust and impurities in the air adhere to the inner wall of the internal pipes of the air sampling device, making it difficult to clean the gas sampling device and causing interference with the subsequent gas sampling test results. Furthermore, the air sampling device collects air from a fixed location, allowing only gas sampling at a specific point. This results in significant errors in gas detection and makes it difficult to comprehensively assess gas quality. Therefore, a sampling device for environmental monitoring is needed.
