A real-time water sample collection system and collection method thereof

Abstract

The invention discloses a real-time water sample acquiring system which comprises a towed body arranged in a sampling water area, a water sampling pipe, a water sampling device, a hydrological parameter detector and a location device, wherein the water inlet end of the water sampling pipe is arranged on the front end of the towed body; the water sampling device is communicated with the water outlet end of the water sampling pipe, and is used for acquiring a water sample through the water sampling pipe; the hydrological parameter detector is used for detecting hydrological parameters of the sampling water area; and the location device is used for obtaining geographical location information of the sampling water area. The real-time water sample acquiring system can be used for acquiring a water sample suitable for trace analysis, can continuously work when a ship is in a sailing state and can also be used for recording hydrological data and location information of the water sample in real time. The invention also provides a real-time water sample acquiring method. According to the invention, hydrological data such as temperature, salinity and depth are monitored in real time while the water sample is acquired, and a real-time and synchronous water sampling sailing track is obtained through a global positioning system and data acquisition. The system and the method meet the requirement of trace analysis sampling and dynamic continuous sampling and further provide detailed real-time sailing track and hydrological information.

Description

technical field [0001] The invention belongs to the fields of trace analysis chemistry and environmental science, and in particular relates to a real-time water sample collection system and a collection method thereof. Background technique [0002] Collecting natural water samples (including: rivers, lakes, oceans, etc.) and analyzing their physical and chemical indicators is an important part of physical, chemical, biological, and environmental science research on natural water samples. The complexity of the medium in natural water samples places high demands on the precision and accuracy of sample collection and analysis. Collecting uncontaminated water samples is a necessary prerequisite for truly reflecting the characteristics of the samples, which also puts forward higher requirements for the water collection system. At present, most of the water harvesting systems on the market belong to the fixed-point water harvesting type, that is, when the shore or the ship is sto...

Problems solved by technology

However, for the collection of surface water samples, due to problems such as hull contamination and surface water pollution, the existing water collection system cannot meet the needs of continuous sample collection without contamination

In recent years, some towed mobile water collectors have been invented and reported in China, including continuous water sample collection devices that use sensors and submersible pumps in the towed body to achieve controllable water sampling depth, but none of them can overcome the potential problems in the water sample collection process. Contamination problem, and it is impossible to obtain the ship's trajectory during sample collection in real time, as well as important hydrological parameters such as temperature and salinity
