Description

Technical Field

[0001] This invention relates to the field of atmospheric dust sampling technology, and in particular to a sampler that collects both dry and wet deposition. Background Technology

[0002] Dry and wet deposition in the air is an important monitoring item for atmospheric environmental monitoring in my country. Dry deposition refers to the process by which various particles suspended in the atmosphere settle at their own terminal velocity; wet deposition refers to the process by which various particles suspended in the atmosphere settle due to the scouring effect of precipitation. Southern and northern my country experience frequent rainfall in summer, requiring large amounts of precipitation samples to be evaporated, increasing measurement and analytical errors, and even causing sampler overflows during heavy rain. Current dry and wet deposition samplers mainly consist of precipitation sensors, precipitation collection devices, dust collection devices, and a control system.

[0003] CN101013070A discloses a multi-functional fully automatic sampler for rain and dustfall, which automatically collects rainwater during rainfall using a rain sensor and can continuously and automatically collect dustfall samples from different time periods. CN 209166918U discloses a fully automatic continuous rain and dustfall sampler, which includes a rainwater collection tank, a dustfall collection tank, and a rain sensor on the housing, and a segmented collection mechanism inside the housing. After receiving a signal, the rain sensor sends a signal to a programmable controller, which then sends a signal to a solenoid valve, which controls the opening of the guide pipe. CN 204359560U discloses a multi-functional automatic atmospheric dustfall sampler, which consists of a rainwater sensor controller, a non-directional transmission device, a housing, and a dustfall collection tank. The rainwater sensor can automatically send a signal to the controller to automatically collect rainwater 5-10 seconds after it starts raining, while simultaneously shutting off the collection of dry dustfall samples. CN105784424A discloses an automatic dry and wet dust sampler for sand source areas, equipped with a solar panel, a battery, and a precipitation sensor. The motor, battery, and precipitation sensor are electrically connected to a PLC controller. A cover plate rotatable around a pivot in the horizontal plane is included, with the pivot connected to a motor mounted on a base for control. CN107192585A discloses a micro-powered rain and dust collection system, including a water collection tank, a time-sharing collection tray, a sample storage bottle, a precipitation sensor, and a controller. The bottom end of a collection pipe is located inside the rotating tray and connected to a connecting pipe. The time-sharing collection tray has multiple spaced branch pipe holes. The rotating tray is driven by a first power mechanism to rotate, aligning the water outlet of the connecting pipe with each branch pipe hole. The water is collected in the sample storage bottle. All of the above samplers use precipitation sensors and control systems, requiring power and signal control systems, and have complex structures. Summary of the Invention
