Surface water sampling device for water quality detection

Abstract

The invention discloses a surface water sampling device for water quality detection. The device comprises a cylinder body, a telescopic mechanism positioned in the cylinder body and an opening mechanism positioned on one side of the cylinder body. Compared with the prior art, the surface water sampling device for water quality detection adopts a telescopic spring to ensure that a cover body shields an opening, so that when the device enters water, surface water cannot enter a water storage layer; a floating ball in a second cavity is lifted upwards after being stressed, the telescopic spring is pressed to bend a bending mechanism, a second connecting rod is pushed to move rightwards to drive the cover body and a communicating pipe to move rightwards to open the opening in the communicatingpipe, so that the communicating pipe communicates with a water inlet passage, water enters the water storage layer through the opening mechanism, and the device is reasonable in structure, has a delayed sampling function, guarantees the water sampling quality and is suitable for popularization.

Description

technical field [0001] The invention relates to a water quality detection sampling device, in particular to a surface water body sampling device for water quality detection. Background technique [0002] Water source is the general term for the source and existence form of water. Water is the source of life, an important intermediary for material, information, and energy transmission, and an irreplaceable resource for the survival of organisms on the earth's surface. Water sources mainly exist in areas such as oceans, rivers and lakes, glaciers and snow-capped mountains. They are updated in the form of big steam sports and so on. Water is a precious resource that human beings cannot live without. [0003] The water quality detector can quickly and accurately analyze and detect the sampled water quality, so it is applied to the detection of many industries, such as the most common aquaculture, waterworks, and environmental protection detection industries, but for the accur...
