Portable sewage sample collecting device

Abstract

The invention relates to the technical field of environmental protection, in particular to a portable sewage water sample collection device, comprising an electric telescopic rod and a rotating shaft, the right end of the electric telescopic rod is connected to a first sampler through the rotating shaft, and the first sampler The right side is slidably connected with a second sampler, the right end of the second sampler is slidably connected with a third sampler, the top of the first sampler is fixedly connected with a bracket, and the top of the bracket is rotatably connected with a pulley, and the pulley A rope is connected to rotate on the top, and the other end of the rope is fixedly connected with a sampling tube cover, and the two sides of the sampling tube cover are fixedly connected with tension springs. , the second sampler and the third sampler form a retractable and foldable sampling device, which is more convenient to carry. This design concept is novel, scientific in design, has huge economic benefits and broad market prospects, and is worth popularizing and using.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a portable sewage water sample collection device. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The main monitoring items can be divided into two categories: one is a comprehensive indicator reflecting the water quality status, Such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand, etc.; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium , cadmium, mercury and organic pesticides, etc. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above monitoring items, sometimes it is necessary to measure the flow...

AI Technical Summary

Problems solved by technology

[0003] Most of the sewage water sample collection devices currently on the market are either too simple in structure, and the collection and measurement of sewage cannot meet the standard requirements and specifications. When conducting research, the data is not authoritative and representative, or the volume is large , is not suitable for portable use, and has certain limitations when used. Some sewage sampling devices do not achieve layered sampling, and the sampled data is not completely reliable. Therefore, a portable sewage water sample collection device is proposed to solve the above problems.
