Water body sampling device

Abstract

The invention discloses a water body sampling device. The invention relates to the technical field of river liquid water sampling. An anti-skid sleeve pad fixedly sleeves a negative pressure type drainage unit; an impurity filtering unit is fixedly arranged at the lower middle position in the negative pressure type drainage unit; a sealing cap is fixedly arranged at the bottom of the negative pressure type drainage unit in a sleeving manner; a water pumping pipe is fixedly connected in series to the bottom end surface of the sealing cap. In a water body sampling process, a water body and impurities in the water body are divided into two parts; later-period detection personnel can conveniently and separately detect the two parts; the improvement of the whole water environment is facilitated. A filtering assembly is arranged in the impurity filtering unit, and the filtering assembly is in threaded connection with an external supporting wall, so that part of the filtering assembly can bedetached from the whole water body sampling device, a filtering net existing in the filtering assembly can be cleaned or replaced conveniently, the accuracy of later-period detection data is improved,and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of river liquid water sampling, in particular to a water body sampling device. Background technique [0002] The route through which a river flows, usually referring to a navigable waterway. The Yellow River waterway, another place name waterway. The goal of river leveling is to form afforestation along both sides of the river, to seal the river and grow grass, to restore vegetation, to suppress poplar dust, to control pollution sources, and to form an ecological river. Rivers are divided into five grades, namely, first-class rivers, second-class rivers, third-class rivers, fourth-class rivers, and fifth-class rivers. River earthwork leveling method has been well applied in the dredging of Yongding River and Chaobai River in Beijing, and the effect is also very good after the completion of the project. For the earthwork of the river course, first use the part of soil above the designed river bottom to fil...

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a water body sampling device, which solves the problem of the existing water body sampling device, whose internal water body filtering structure cannot be removed and replaced, so that when the device is used for the second time, the water body residue from the previous time remains In the filtration structure, the inaccuracy of water body detection data after secondary use, and the inability to sample water bodies at different depths in one sampling operation
