Deep water sampling system

Abstract

The invention relates to a deep water sampling system. The system comprises a generator, a sampling container, a sampling container fixing base, a water inlet, a water outlet, a vent valve, a vacuum negative pressure gauge, a water sample intake, a water pump and a sampling water tube, wherein the generator provides power support for the system; the water inlet, the water outlet, the vent valve, the vacuum negative pressure gauge and the water sample intake are arranged on the sampling container; the water pump is connected with the sampling container; a bottom valve and a heavy object are connected to the sampling water tube; the sampling water tube is provided with a water depth detector; the generator is connected with the water pump; the water pump is connected with the water outlet on the sampling container; and the sampling water tube is connected with the water inlet on the sampling container. The whole system adopts the water pump to pump water and the front end of the water pump is connected with the sampling container for sampling a water sample, so that the may influence of water flow passing through the pump on sampling of the water quality is avoided. The system has simple structure, is convenient to operate and use and is economic and practical. Water at different depths of deep water areas such as rivers, lakes and the like and narrow water areas such as a mountain channel deep reservoir and the like without large-size ships can be accurately sampled.

Description

technical field [0001] The invention relates to deep water sample sampling technology, in particular to a deep water sampling system used in deep water areas such as rivers and lakes, as well as narrow water areas such as mountain channel deep reservoirs without large ships. Background technique [0002] With the increasing intensity and speed of water resources development and utilization, people's awareness of ecological environment is increasing day by day, and water environment issues are gradually paid attention to at home and abroad. At present, water environment is the focus of domestic environmental protection and project environmental assessment related work. Water quality elements, as water environment evaluation indicators, are important indicators to measure the degree of damage to water areas and whether drinking water is healthy. Accurate water quality indicators can provide a reliable basis for environmental protection, and water sample collection is an importa...

Problems solved by technology

However, the working environment during sampling is often a river with a very fast flow rate. The suspended cable with scales will float with the current in the turbulent water flow, rather than perpendicular to the river surface. The scale displayed by the suspended cable can neither accurately reflect the The depth of the river water sample; and the sampling cylinder must be lifted by the winch to take out the water sample, and it is impossible to achieve multi-point continuous sampling
