River water sampling detection device for environmental assessment and use method thereof

Abstract

The invention discloses a river water sampling detection device for environmental evaluation and a use method thereof, and relates to the technical field of river water sampling detection devices. The device comprises a floating platform supporting assembly, a first connecting rope and a sampling assembly, the sampling assembly comprises a sampling barrel, a sealing cover, a curved surface moving part and an air bag part; the sealing cover is in threaded running fit with the sampling barrel; the curved-surface moving part is in sliding fit with the sampling barrel; the inner wall of the sampling barrel is in sliding fit with a limiting assembly. According to the invention, the driving motor is started to drive the plurality of sampling assemblies to do lifting motion, and the length of the first connecting rope between the adjacent sampling barrels is controlled, so that sampling collection at different specified depths in a sampling area is realized; the air blower is started to introduce air into each group of air bag components, the curved surface sealing plate is driven to move, the water inlet groove is opened, river water with different depths enters the corresponding sampling barrels, the air in the air bag components is exhausted, and the curved surface sealing plate seals and blocks the water inlet groove.

Description

technical field [0001] The invention belongs to the technical field of river water sampling and detection devices, in particular to a river water sampling and detection device for environmental assessment and a use method thereof. Background technique [0002] With the development of the times, environmental protection has become more and more important, especially for water resources, which are the necessary energy for human survival. Therefore, in the process of daily environmental inspection and restoration, it is necessary Resources are sampled and tested. [0003] However, there are some shortcomings in the integrated device for sampling, collection and detection of river water for environmental assessment on the market. The traditional collection and detection device has a relatively single collection capacity. Usually, the pumping hose is put into the river water at a specified depth and the pump is used for fixed-point sampling. , It is impossible to collect river w...

[0003] However, there are some shortcomings in the integrated device for sampling, collection and detection of river water for environmental assessment on the market. The traditional collection and detection device has a relatively single collection capacity. Usually, the pumping hose is put into the river water at a specified depth and the pump is used for fixed-point sampling. , it is impossible to collect river water at different depths synchronously, and it is difficult to drain the remaining river water in the pumping hose, which affects the final data of sampling collection and detection, and increases the operating intensity of the staff
