Description

TECHNICAL FIELD

[0002] In the process of surface water resource investigation, a large amount of natural gas is often found to be emitted from water bodies in river, lake, well and other water system environments. These gases often appear from the water bottom, float to the water surface and then dissipate in the atmosphere. Such gases have diverse compositions, most of which are greenhouse gases such as carbon dioxide (CO2), methane (CH4) and hydrogen sulfide (H2S), and also contain a small amount of rare and valuable helium gas (He). The large amount of CO2, CH4 and H2S gas overflowing from the water system can cause great harm to the natural environment and human life, so it is crucial to discover and prevent it as soon as possible.

[0003] The existing collection devices for natural gas in rivers, lakes and other water systems are mostly floating on the water surface. By placing the collection device in the target water area, the collection device floats on the water surface to achieve the purpose of collecting natural gas in water. For example, the patents with application numbers 202020756859.6 and 202120596179.7 achieve gas collection by floating on the water surface for a long time. However, due to the influence of wind and water flow, the water surface will not always remain still, so the changes in the water surface will inevitably disturb the data collection and affect the accuracy of the data. At the same time, the collection and adjustment of the instrument device also need to be assisted by a ship, which is relatively troublesome.
