Simultaneous sampling device of multiple water layers for water body pollution detection

Abstract

The invention relates to the technical field of meters and instruments, and discloses a simultaneous sampling device of multiple water layers for water body pollution detection. The simultaneous sampling device comprises an operating floor, and a bracket is fixedly connected above the operating floor; an elliptical disk drives a first connecting rod to move, so that a second connecting rod and a third connecting rod rotate with a lug at the joint of which as a rotation point, the third connecting rod moves up and down to drive a pressing plate to synchronously move, the pressing plate is squeezed away from a rubber ball, when the rubber ball squeezes a gear lever, the gear lever moves downward to deviate from a moving rod to drive a waterstop to separate from a water inlet, sewage from different water layers is filled into a collection chamber respectively, and the rubber ball is squeezed, the air is discharged into the water, the sewage is sucked into a collection bottle from the water inlet, the sampling speed is accelerated, as the water level rises, a floating block moves up to block a pass hole of an air conveying pipe and blocks the water inlet, when the rubber ball is strokeand it is discovered that the deformation degree thereof is smaller, it indicates that the sewage in the collection bottle has been collected, thereby reaching an effect of simultaneous water collection at different water layers.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to multi-water layer simultaneous sampling equipment for water body pollution detection. Background technique [0002] Instrumentation refers to equipment that uses scientific principles to measure, detect, and observe research objects to obtain various physical quantities, material components, and property parameters. If it is classified according to its purpose and use, it includes environmental protection instruments, environmental protection Instrument refers to everything related to environmental protection, which can be produced in a factory and can be replaced by an independent instrument, including water pollution analysis instruments. Before the sewage is recorded and analyzed, it is necessary to sample the sewage. At present, there are the following problems in the sampling of the water body : [0003] Since the water body is divided into surface layer, interlayer and...

AI Technical Summary

Problems solved by technology

[0003] Since the water body is divided into surface layer, interlayer and deep layer, it is necessary to analyze the sewage in different water layers separately. However, when sampling sewage, the general equipment can only sample the sewage in a single water layer, and it is often necessary to replace the equipment and take multiple samples. , the operation is cumbersome, not convenient enough, and it takes a long time, the work efficiency is low, and because the equipment is placed under the water surface, it is inconvenient for the operator to know the sampling situation, which may easily lead to insufficient sample volume or too long sampling time
