Portable sampling device for field use and method of use thereof

Abstract

The invention relates to a field portable sampling device; a shell is internally provided with a power supply chamber, a water pump chamber and a solution chamber, wherein the power supply chamber is internally provided with a lithium battery; an outer shell of the power supply chamber is provided with a switch; the water pump chamber is internally provided with a water pump; the switch and the water pump are electrically connected with the lithium battery by electric wires; the solution chamber is divided into a solution filtering chamber and a solution collection chamber by a clapboard; the height of the clapboard is lower than that of the solution chamber; a water inlet of the water pump is connected with a water inlet pipe which extends outside the shell; a water outlet of the water pump is connected with a water outlet pipe; a pipe orifice of the water outlet pipe is communicated with the solution filtering chamber; the bottom of the solution filtering chamber takes on a funnel shape and is provided with a slagging hole; the solution collection chamber is transparent, and the bottom of the solution collection chamber is provided with a liquid discharge hole; and a liquid discharge valve is arranged on the liquid discharge hole. The field portable sampling device solves the technical problem that other mechanical power water pumps can not work normally since the field is lack of electric energy, so that manpower and material resources are saved, and the working efficiency of sampling is increased. The field portable sampling device also overcomes the defect the existing pedal absorber or mechanical sampling device is less in absorbing quantity.

Description

Technical field: [0001] The invention relates to a portable field sampling device and its application method, which is especially suitable for extracting leached water and runoff water in the process of farmland nitrogen and phosphorus monitoring when there is no power in the field, and belongs to the technical field of agricultural equipment. Background technique: [0002] As people pay more and more attention to the safety of agricultural environment, especially considering the impact of farmland nitrogen and phosphorus nutrient leaching and runoff loss on water eutrophication, more and more researches are now focusing on the non-point source pollution of farmland fertilizers. At present, the long-term positioning monitoring devices for nitrogen and phosphorus leaching loss and runoff loss in the field are mainly in-situ soil leaching solution collectors and runoff collection pools, such as the in-situ monitoring device for farmland underground leaching disclosed in Chinese...

Problems solved by technology

However, the general DC water pump needs to be connected to the DC external power supply. To control the operation of the water pump, you need to disconnect and connect the power cable, which is not only difficult to carry, but also extremely inconvenient to operate. In addition, it is very inconvenient to charge the DC power supply.
