Portable sewage sample collecting device

Abstract

The invention relates to the technical field of environmental protection, in particular to a portable sewage sample collecting device which comprises an electric telescopic rod and a rotary shaft. A first sampler is rotationally connected with the right end of the electric telescopic rod by the rotary shaft, second samplers are slidably connected with the right side of the first sampler, a third sampler is slidably connected with the right end of the corresponding second sampler, supports are fixedly connected with the top of the first sampler, pulleys are rotationally connected with the topsof the supports, ropes are rotationally connected onto the pulleys, a sampling tube cover is fixedly connected with the other end of each rope, and extension springs are fixedly connected with two sides of each sampling tube cover. The portable sewage sample collecting device has the advantages that a telescopic and foldable sampling device comprises the electric telescopic rod, the rotary shaft,the first sampler, the second samplers and the third sampler, and accordingly the portable sewage sample collecting device is convenient to carry; the portable sewage sample collecting device in the design is novel in concept and scientific in design, has a huge economic benefit and an extensive market prospect and is worthy of being popularized and utilized.

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.
