Description

Automatic water sampling device and a suitable method of water collection {{Automatic water sampler and method}

The present invention relates to an apparatus for measuring marine environment information, and more particularly, to an apparatus for automatically collecting sea water by location and by water layer, and a method for collecting water suitable therefor.

In Korea, the three sides of the terrain are in contact with the sea, which has many economic effects from nearby marine resources, and if such marine resources are polluted or temperature changes occur, it is directly or indirectly affected by the surrounding climate and living environment. It is a reality.

In addition, due to land development and industrialization, land soil flows into nearby oceans, or various environmental pollutants are introduced or dumped, causing marine pollution.

Due to the topographical conditions of Korea, the sea, especially the surrounding marine environment, is directly or indirectly intimately connected with real life, and if it is polluted, it will affect national health and national economics.

It is also important to prevent the soil from entering the land, the introduction of various environmental pollution blisters, or the dumping to clean the surrounding marine environment.However, the marine environment is inevitable due to natural influences and unavoidable circumstances caused by temperature changes due to global warming. In order to be prepared for this serious change, it is necessary to promptly and accurately investigate the condition of the surrounding marine environment or the marine environment of the designated area and take appropriate response.

The prior art marine environment survey is a method in which a manpower with expertise navigates to a specific ocean using a vessel, and measures the state of inspection and environmental change through direct survey and sampling of the ocean.

However, the number of people with expertise is relatively small and it takes a long time to be skilled at the same time, and the sea area to be investigated is very wide, and the ocean is severely threatened to safe voyage due to the severe climate change. Due to the very limited date, it is often difficult to make the necessary surveys and measurements. In addition, the continuous investigation in real time due to the rapid climate change of the ocean is very difficult reality.

Therefore, the conventional marine survey method as described above is very economically burdensome, and has been limited in time by the physical and climatic conditions of the researchers or specialists, and at the same time there is a problem that cannot be investigated in real time.

Some improvement of the problems of the prior art as described above is a method of installing a fixed buoy.

BUOY talks about mooring buoys, is fixed not to float in a specific area of the sea, and it is equipped with various measuring and observing equipment, so that wind, air pressure, temperature, humidity, water temperature, digging, flow rate, etc. There is an advantage of acquiring various marine environment information included in real time.

Since buoys are fixed on a specific specific sea, there are very limited sea areas for obtaining information, and in order to acquire marine environment information in a large sea area, buoys need to be installed in many sea areas, which is economically burdensome. Still remains.

In addition, since it is fixedly installed at a specific sea, various attached organisms are parasitic and degrade or degrade the performance of precise high-value measuring equipment, requiring periodic management, such as the reliability of the measured information decreases over time and maintenance costs. This takes a lot of trouble and so on.

Another solution to the above problem is an unmanned measuring vessel that safely and automatically navigates a large sea area at a reasonable cost, arrives at a designated sea area, collects marine or sea water samples, and precisely measures marine environment information in real time. To operate.

These unmanned measuring vessels are equipped with GPS equipment and perform seawater measurement, seawater collection, etc. while navigating the designated sea area under the control of the marine center.

Unmanned measuring vessels are not embarked by skilled technical personnel, so they can operate in designated areas even in bad weather and require low maintenance costs, and have the advantage of quickly and accurately measuring real-time marine environment information in designated areas.

In order to collect seawater using such an unmanned measuring vessel, an automatic water collecting device for collecting seawater by location and water layer is required.

An object of the present invention is to provide an automatic water harvesting device that collects and stores seawater by location and by water layer, which is devised to meet the above requirements.
