Description

Technical Field

[0001] The utility model relates to the technical field of dust sampling and detection, in particular to a building dust sampling and detection device for building safety detection. Background Art

[0002] With the accelerated pace of urban development and the vigorous development of urban construction, urban buildings are constantly expanding. However, during urban construction, dust caused by construction is also constantly generated. Dust can enter the lungs of construction workers through the nasal cavity or throat, causing a variety of diseases. Therefore, it is particularly important to detect the dust generated during construction.

[0003] When detecting dust, the operator usually pushes the device to the construction site and uses an air pump to absorb the dust into the device for detection. However, the adsorption tube of most existing detection devices is fixedly installed on the device, so it can only absorb and detect dust in one direction. The dust generated in the same place may be different due to different construction materials. If the dust generated in other directions needs to be adsorbed and detected, the device needs to be manually pushed to change its direction. If the ground is muddy or bumpy, it is time-consuming and labor-intensive to manually push the device. Utility Model Content
