Time-phased automatic rain sample sampling device

Abstract

The invention provides a time-phased automatic rain sample sampling device. According to the time-phased automatic rain sample sampling device, a collection hopper is mounted in the middle of an instrument top disc; the instrument top disc is mounted at the top of a barrel; solenoid valves, a pressure sensor and a rotary device are connected with a power supply and a control system; a sampling bottle tray is mounted in the barrel; a sampling bottle is located above the sampling bottle tray; a hollow rotary shaft is located at the center of the barrel; a rotary barrel is connected with the hollow rotary shaft; the rotary device is connected with the hollow rotary shaft; a water outlet of the collection hopper is located above the rotary barrel; a pipe is connected with the rotary barrel; a water outlet of the pipe is located above the sampling bottle; a part, which is close to the water outlet, in the collection hopper is provided with the pressure sensor and the solenoid valve; the pressure sensor is located above the solenoid valve and the pipe is internally provided with the solenoid valve; the hollow rotary shaft is internally provided with the solenoid valve. The time-phased automatic rain sample sampling device is simple in structure, can be used for automatically and accurately collecting rain samples at fixed time, and achieves environment-friendly and energy-saving effects.

Description

Technical field [0001] The invention relates to a rainfall sampling device, in particular to a sampler capable of automatically performing sampling, and a sub-period rain sample automatic sampler capable of collecting rainfall and rain samples at different periods. It belongs to the field of hydrological experiment. technical background [0002] Currently, there is no sampling instrument for rain samples on the market. In the direction of hydrological research, the research on rainfall has gradually expanded from the initial quantitative research to the sample research. In addition, due to the aggravation of environmental pollution, the research on the concentration changes of pollutants in rainwater has attracted more and more attention. So far, the research on the content of pollutants in rainwater in the direction of hydrology and meteorology has adopted manual sampling, which has a large workload and many uncertain factors. In addition, in some remote areas, it is difficul...

Problems solved by technology

Because the water delivery rod is movably connected with the connecting conduit, as far as the prior art is concerned, the simple structure cannot seal the connection between the water delivery rod and the connecting conduit during water injection, that is to say, the water injection mechanism cannot seal the water delivery rod and the connecting conduit when injecting water. Connections that allow water to leak from the junction of the water delivery rod and the connecting conduit, thereby inaccurately measuring rainfall

The structure is too complex
