Water sample extraction and storage device for watercourse water quality detection

Abstract

The invention discloses a water sample extraction and storage device for watercourse water quality detection. The device comprises a base, wherein a water guide cavity is mounted on the left side of the upper end of the base; a lifting piston is arranged in the water guide cavity; a lifting rod is mounted in the middle of the upper end of the lifting piston; a guide plate is mounted in the middleof the upper end if the lifting rod; a guide rod is mounted in the middle of the upper end of the guide plate; a first support rod is mounted on the left side of the upper end of the water guide cavity; a second support rod is mounted on the right side of the upper end of the first support rod; a water storage tank is mounted in the middle of the upper end of the base; a mixing shaft is arranged in the water storage tank; a rotation cam is mounted in the middle of the upper end of the mixing shaft; a traction motor is mounted on the left side of the upper end of the second support rod; a traction wheel is mounted in the middle of the traction motor; the traction wheel is wound with a traction cable; a fixed pulley is wound with the left end of the traction cable; and the tail end of the traction cable is connected with a water-proof tank. The device achieves sampling of water quality of different water levels of a watercourse; water samples are stored in a disturbance manner after water quality sampling; and a phenomenon of static settlement of the water samples is avoided.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a device for extracting and storing water samples for river water quality detection. Background technique [0002] Water is the source of life. Human beings cannot do without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, not only between cou...

Problems solved by technology

[0004] Before water quality testing, water quality sampling must be carried out first, but the existing water quality sampling device has a complex structure, and cannot quickly sample the water quality of the water level at the bottom of the river bottom, and it takes a long time and low efficiency to sample the water level in other places. After water sampling, we will temporarily store the water because we cannot detect it in time. However, during the storage process, because it is left standing, a part of the suspended matter in the water will be precipitated, which seriously affects the quality and quality of the later water quality testing. Detection efficiency, poor practicability
