Abstract

The invention discloses a full-automatic day-parting rainwater sampling device which comprises a power module, a rainwater sensor, a micro-programmed control unit (MCU), a stepping motor, a stepping motor driver, a rainwater collection module, a communication module and an upper computer, wherein the power module is respectively connected with the MCU and the stepping motor driver; the rainwater sensor is connected with the MCU; the MCU is connected with the upper computer for communication by the communication module; the rainwater sensor has a function of starting the operation of the whole rainwater sampling device; the upper computer is used for controlling the MCU by the communication module; the MCU is used for controlling the stepping motor by the stepping motor driver; the stepping motor is connected with the rainwater collection module, so that rainwater can be sampled. The full-automatic day-parting rainwater sampling device is high in practical performance and good in gas-tightness; most of all, the rainwater of different time periods can be collected in different bottles; furthermore, the device is better in the aspect of automatic control and is more humanized.

Description

technical field [0001] The invention belongs to the technical field of meteorological environment sample collection, and relates to a rainwater sampling device, in particular to a sampling device for automatically collecting rainwater samples reflecting different time periods. [0002] Background technique [0003] Rainfall is a common phenomenon in daily life. As the problem of smog continues to intensify, scholars and experts have gradually increased their research on the impact of rainfall on smog. Therefore, how to better collect rain samples has become a concern of scholars. The rainwater sampling device is a tool for collecting rainwater. It plays an important role in collecting rainwater, calculating the rainfall, judging the rain pattern, and analyzing the content of various chemical substances in the rainwater. At present, the precipitation automatic sampling device used in China mainly includes rain sensor, dust cover, rain gauge and precipitation collection devic...
