Description

Technical Field

[0001] The utility model belongs to the field of testing platforms for environmental testing, and specifically relates to a testing platform for environmental testing. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the environmental quality status. Environmental monitoring is to determine the environmental pollution status and the level of environmental quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators and ecosystems. A testing bench is required for environmental testing, but the existing testing bench does not have a purification function. Direct discharge after detecting harmful gases will cause pollution again.

[0003] A Chinese patent with publication number CN213669395U discloses a test bench for environmental testing, including a support box, the top of the support box is fixedly connected to a test bench body, the bottom of the inner cavity of the support box is fixedly connected to a fan, the left side of the test bench body is connected to an air suction pipe, the surface of the air suction pipe is connected to a one-way valve, the bottom of the air suction pipe is connected to an air supply hose, the left side of the fan is connected to an air inlet pipe, the end of the air supply hose away from the air suction pipe is connected to the air inlet pipe, the right side of the fan is connected to an air blowing pipe, and the bottom of the right side of the support box is fixedly connected to a purification box. The utility model enables the test bench to have purification capability through the coordinated use of a support box, a test bench body, a fan, an air suction pipe, a one-way valve, a gas transmission hose, an air inlet pipe, an air blowing pipe, a purification box, a first filter screen, a second filter screen and an air outlet pipe, so that the toxic or harmful gas after detection is purified before being discharged, thereby avoiding secondary pollution.

[0004] In view of this, the present utility model is proposed. Utility Model Content
