Description

An intelligent water collector

technical field

The invention relates to an intelligent water collector, which is a controllable intelligent water collector that can be mounted on a marine environment monitoring ship in the deep sea field.

Background technique

Marine environmental monitoring is an important part of marine environmental protection and is of great significance to environmental protection and governance. In marine environmental monitoring, some monitoring items and parameters are measured by on-site sensors, and some need to be analyzed by using corresponding instruments and equipment in shore or shipboard laboratories after on-site sampling. Due to technical reasons, nutrients, trace Parameters such as metals often need to collect tens of liters of seawater and bring it back to the laboratory for determination. There are generally two ways to collect seawater: the pump cooperates with the pipeline to pump water, and the seawater collector is lowered to collect water.

The method of using pipelines and pumps to pump water is suitable for quickly collecting a large number of water samples in relatively shallow waters. The working process is that after the marine monitoring ship reaches the target position, the pipeline is manually lowered to the specified depth, and the pump works to collect water. The lowering and recovery of the pipeline requires a lot of manpower. The resistance of the pipeline in the sea current greatly affects the stability of the hull. Time flushing to reduce the pollution of impurities or surface water samples to the required depth water samples.

Traditional manual water collection bottles include Nansen bottles, Nice Gold bottles, Guo Fuluo bottles, Van Dorn bottles and so on. After decades of refinement, dozens of models and sizes of water collectors have been developed, but the basic principle of operation is the same, you put the sampling bottle under the water, slide it down the cable to make the hammer, and trigger the mechanism to close bottle cap. Such a water sampling device can use a winch. Since the inclination of the steel wire rope in the ocean current cannot be controlled, the sampling depth cannot be accurately controlled and recorded. It can only be estimated by the operator based on the on-site visual inspection; It is cumbersome; it often happens that the bottle cap is not closed or the hammer is lost, and it may be necessary to repeatedly lower the water collector to complete a water collection work.

The electric push rod is a waterproof electric push rod with a stroke of 50mm and a thrust of 100Kg, and has the characteristics of lightness, small vibration and precise limit.

The control cabin includes a multi-beam parameter meter and a controller, and the multi-beam parameter meter monitors parameters such as pH value, temperature and water pressure of the seawater in real time, and then stores them in the controller, and detects the seawater in real time The pressure is used to locate the depth at which it is located. When the water collection depth set by the controller is reached, the controller sends a command, and the bottle cap automatic opening and closing device works to close the upper and lower bottle caps to complete the water collection action.

Compared with the prior art, the present invention has the following obvious outstanding substantive features and significant advantages:

The present invention records seawater parameters in real time through a multi-beam parameter meter and measures seawater depth by measuring seawater pressure, and can accurately complete water collection at a specified depth, greatly improving the accuracy of water sample collection and avoiding inaccurate depths The problem of repeated water collection.
