Automatic water sample collection system with controllable depth

Abstract

The invention discloses an automatic water sample collection system with a controllable depth and relates to the fields of water environment monitoring, hydrology and water resources and protection. The automatic water sample collection system comprises three main facilities such as a water intake facility, a water storage facility and an air pump, wherein the water intake facility is connected with a vertical fixing rod by virtue of a water intake pipe; the fixing rod is connected with a fixing rack and arranged in a top-bottom adjustable manner; scales are arranged on the fixing rack; the fixing rack is fixed on a boat by virtue of retaining screws; an external probe joint is arranged at the bottom of the fixing rod; the other end of the water intake pipe is connected with a sealing box;a sealing cover is arranged on the sealing box (water storage facility); a water inlet hole is formed in the sealing box and connected with the water intake plate; a rotatable sample bottle holder isarranged in the sealing box and is capable of loading a certain quantity of water sample bottles for collecting water samples; an exhaust hole is formed in the sealing cover; the pressure in the sealing box is reduced by exhausting so as to automatically take water. The automatic water sample collection system disclosed by the invention is controllable and safe, automatic water intake can be realized, and security risk in the water sample collection process is reduced to the lowest.

Description

technical field [0001] The invention relates to the fields of water environment monitoring, hydrology and water resources and protection, and in particular to an automatic depth-controllable water sample collection system. Background technique [0002] In recent years, people have paid more and more attention to water environment safety issues, and the quality requirements for water environment monitoring have also become higher and higher. To further strengthen the management of water environment monitoring, effectively improve the level of water environment monitoring, and dynamically understand the pollution and quality of water resources is the current The key work of my country's water environment, the water environment monitoring of "big rivers and rivers" will be the top priority of this work, so large-scale water sample collection and analysis will become more frequent in the future. Among them, an effective, safe and fast water sample collection system is essential i...
