Water quality sampling box

Abstract

The invention discloses a water quality sampling box which comprises a supporting base. A supporting vertical rod is fixedly arranged on the top face of the supporting base. A plurality of positioningholes A are formed in the supporting vertical rod, a fixing rod A is fixedly arranged at the portion, close to the bottom end, of the supporting vertical rod, a reel A is rotationally connected to the fixing rod A, the supporting vertical rod is hinged to a supporting transverse rod through a hinge device, a plurality of positioning holes B are formed in the supporting transverse rod, and a fixing rod B is fixedly arranged at one end of the supporting transverse rod. Due to ascending and descending of a steel wire rope, the device can be effectively controlled to stop at any depth in water, aworker can conveniently perform water sample collection at different water levels, the box can adapt to factors of different distances to the shore and different heights from the water surface, precise sampling can be performed on the water quality at the preset position, water samples of different volumes can be collected through multipledifferent sampling bottles so that a worker can conveniently collect more samples, more working time can be shortened, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a water quality sampling box. Background technique [0002] With the rapid development of modern economy and industry, the pollution to the environment is also intensified, especially the pollution of air and water resources, which directly affects the living environment and health of human beings. Environmental protection has been paid more and more attention by the country and the people, and the protection of the environment should be carried out simultaneously from multiple aspects such as prevention and governance. [0003] The premise of water pollution control is the need for accurate sampling and testing. The distance from the same river to the bank is different, the flow velocity is different, and the pollution and self-recovery conditions are also different. When assessing the water quality, the water quality at different locations of the river width sh...

AI Technical Summary

Problems solved by technology

However, most of the existing water quality sampling equipment cannot accurately locate and sample the predetermined position in the width direction of the river, and some equipment that can accurately locate can only perform fixed-point sampling at a single distance. , Difficult to operate, and not versatile; each time multiple, multi-point sampling is performed, multiple devices are required to perform

And in many cases, the volume of the water volume obtained by collecting water samples is not the same, which will also make the water quality data at the detection place inaccurate, so it is necessary to collect water samples of different volumes many times, which will be very troublesome and delay a lot of time. Work efficiency is severely reduced
