Field liquid automatic sampling handcart

Abstract

The invention discloses a field liquid automatic sampling handcart. The field liquid automatic sampling handcart comprises an object carrying plate, wherein the upper surface of the object carrying plate is provided with a slide groove; a slide block is arranged in the slide groove; the upper surface of the slide block is fixedly connected with a retaining block; the left side surface of the retaining block is fixedly connected with a telescopic device; the left end of the telescopic device is fixedly connected with the right side surface of a retaining plate. The field liquid automatic sampling handcart has the advantages that by arranging a control panel, a water pump, a fixed pulley, the retaining block, the telescopic device, the slide block, the slide groove, a damping device, a firstelectrical push rod, a first telescopic rod and a first spring, a water suction pipe can move down, one end of the water suction pipe can extend into water, a water pump is controlled to work, and the water suction pipe can suck the water into a casing, so as to sample a water body; the collection of the water sample by a worker is not needed, the time of the worker is shortened, and the labor intensity is improved; the worker does not need to carry multiple tools, so that the sampling is convenient, and the working efficiency of the worker is improved.

Description

technical field [0001] The invention relates to the technical field of field sampling, in particular to an automatic field liquid sampling trolley. Background technique [0002] Collect water samples from polluted water bodies and analyze and measure them to obtain basic data on water body pollution. Water samples for analysis should be representative and reflect the chemical composition and characteristics of the water body. The method, location, time, and frequency of sampling are all determined according to the characteristics of the water body and the purpose of analysis. [0003] In the research of various environmental factors, it is often necessary to conduct sampling research in the research object area. However, most of the existing technologies use manual sampling. Due to the large amount of collection, the time and physical strength of the workers are wasted, and the collection efficiency of the workers is reduced. Reduced, and workers need to carry a lot of aux...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a trolley for automatic sampling of field liquids, which solves the problem that most of the prior art uses manual sampling. Due to the large amount of collection, the time and physical strength of the workers are wasted, and the labor force of the workers is greatly reduced. The collection efficiency is reduced, and workers need to carry a lot of auxiliary tools into sampling bottles and extractors when collecting, which brings a lot of inconvenience to sampling
