River water quality detection sampling device

Abstract

The invention discloses a river water quality detection sampling device which comprises a telescopic main rod, wherein an antiskid sleeve and a rope winding ring are fixedly arranged on the outer surface wall of the telescopic main rod sequentially from top to bottom; an internal thread of the telescopic main rod is engaged with an external thread of a telescopic auxiliary rod; an annular fixing buckle is arranged on a sampling fixing ring fixedly connected to the lower surface wall of the telescopic auxiliary rod; a sampling bottle is arranged in the annular fixing buckle; the sampling bottleis rotatably connected with a sealing cover through a rotating hinge; a magnetic block is arranged on the outer surface wall of the sampling bottle; a turbine flowmeter is mounted on an extension connecting rod fixedly connected to the lower surface wall of the sampling fixing ring; a thermometer and a pressure sensor are symmetrically mounted on the outer surface wall of the turbine flowmeter; ahook is fixedly mounted on the lower surface wall of the extension connecting rod. The device disclosed by the invention is simple in structure and easy to operate; without an electronic device, thedevice is rarely damaged, thus the production cost, the using cost and the maintaining cost are relatively low; moreover, the bottle body is easy to clean.

Description

technical field [0001] The invention relates to the technical field of water quality testing and sampling equipment, in particular to a river water quality testing and sampling device. Background technique [0002] In environmental water quality monitoring, sampling is the first step in water quality monitoring. Only accurate sampling can ensure the smooth progress of water quality analysis. According to relevant guidelines and standard requirements, surface water quality sampling is usually located between 0.5m below the water surface and 0.5m from the river bottom. In other special cases, such as deep wells and water quality sampling in water treatment units, many sampling requirements are different. Depth water sampling. At this stage, many water quality samples are taken manually using glass bottles. This method can be used for shallow sampling, and it is easy to mix in water at other depths during the sampling process, and it is also dangerous when sampling in some lar...

Problems solved by technology

At this stage, many water quality samples are taken manually by using glass bottles. This method can be used for shallow sampling, and it is easy to mix in water from other depths during the sampling process. It is also dangerous when sampling in some large water bodies.

In addition, the existing water quality sampling device is unknown to the sampling water pressure, water temperature and water flow rate, and cannot provide more sufficient data in the later water quality testing process, and the test results are not ideal
