Multilayer water sample continuous and automatic acquisition type deepwater sampling device

Abstract

The invention discloses a multilayer water sample continuous and automatic acquisition type deepwater sampling device. The deepwater sampling device comprises a barrel which comprises a round top cover, a barrel body and a conical counterweight, water sampling bottles are fixedly arranged outside the barrel body, the barrel body is vertically partitioned into 2-3 inner chambers by partitions in the middle of the barrel body, and a single-chip microcomputer controller and a lithium battery are arranged in the inner chambers respectively. A pressure sensor used for measuring water pressure is fixedly arranged on the outer side wall of the barrel body, a lifting ring and a Bluetooth communication wire are fixedly arranged at the upper end of the round top cover, the lifting ring is connected with a motor lifting device arranged on the water surface, and the Bluetooth communication wire is in wireless communication with a computer on the water surface. Upper and lower end faces of each automatic sampling bottle are provided with water inlets respectively, electromagnetic valves are fixedly arranged at the water inlets respectively, the electromagnetic valves and the pressure sensor are respectively connected with the single-chip microcomputer controller, and the lithium battery is respectively connected with the electromagnetic valves and the pressure sensor to supply power to the same. The multilayer water sample continuous and automatic acquisition type deepwater sampling device has advantages that automatic sampling at six positions different in water depth, and simplicity in operation, high efficiency and continuous sampling of multilayer water samples are realized.

Description

technical field [0001] The invention relates to a water quality sampling device, in particular to a deep water sampling device for continuous and automatic collection of multi-layer water samples. Background technique [0002] With the increasing speed and strength of water resources development and utilization, water environment issues have been paid more and more attention. The water quality element as an evaluation index of water environment is an important index to measure the degree of damage to water areas or whether the water used is healthy. Accurate water quality indicators provide a reliable basis for environmental protection. Water sample collection is one of the important links. It is an important research topic to collect representative water samples that can accurately reflect the concentration and indicators of water quality parameters. [0003] With the intensification of water pollution, groundwater pollution is also increasing, and it has reached a deeper ...

Problems solved by technology

[0004] In the invention patent with the publication number 102128735A, although water quality sampling at different depths can be realized, the entire system relies on water pumps on the water surface, and the underwater and water surface are connected by water pipes. The water samples are prone to cross-contamination, and intelligent automatic operation cannot be realized.

The Chinese invention patent with the application number 201320391655.7 can realize the automation of deep water sampling, but the structure is simple, and only one sample can be taken at a time, resulting in low efficiency
