Supercritical flow water taking device

Abstract

The invention relates to a supercritical flow water taking device. The supercritical flow water taking device comprises a water taking device, a hollow rod connected with the outer side of the water taking device, and a moveable device. The water taking device is a hollow bull horn shape of which two ends are opened. Two ends of the water taking device are provided with a first opening and a second opening, and the inner diameter of the first opening is greater than the inner diameter of the second opening. The hollow rod is a hollow straight tube. The bottom end of the hollow rod is connectedwith the outside wall of the water taking device, and the hollow rod is communicated with the interior of the water taking device. The moveable device comprises a cone rubber stopper, a cable connected with one end of the cone rubber stopper, and a handle connected with the other end of the cone rubber stopper. The cone rubber stopper comprises a bi-directional cone and a fixed part installed atone end of the bi-directional cone. The radius of the bottom surface of the bi-directional cone is greater than the inner diameter of the second opening of the water taking device. The supercritical flow water taking device is capable of greatly relieving the water flow resistance, so the internal air is easily discharged from the tail part under the supercritical flow environment, and the water taking process is convenient.

Description

technical field [0001] The invention relates to the field of environmental science, in particular to a rapid water intake device. Background technique [0002] In environmental science research, the collection and analysis of water samples in different environments is the basis of environmental analysis and evaluation. River water, as an important part of surface water, requires comprehensive and three-dimensional collection. The current water collection work usually relies on speedboats, assault boats, etc. to sail into the center of the river or take samples from the hard-to-reach river bank boundaries. However, due to the wide range of work area space, the sampling process needs to control the time interval not to be too large. In order to allow water samples to be transferred and stored as soon as possible , requiring the speedboat to continue driving. During the driving of the speedboat, due to the high speed, the water flow has great resistance in the lateral directio...

AI Technical Summary

Problems solved by technology

During the driving of the speedboat, due to the high speed, the water flow has great resistance in the lateral direction, and the traditional water dispensers suitable for still water intake are difficult to work normally. For the same reason, the water intake tools such as scoops and buckets are difficult to fill the water at one time, and the efficiency is extremely low. , and easy to get rid of, resulting in losses
