Therefore, if there are air bubbles, dirt, and impurities in the water sample, it will directly affect the measurement results
When the method of supplying water samples is used for long-term operation, due to the pressure change of the pump and the circulation of water samples in different pipelines, there will be phenomena such as air mixing and bubble precipitation. If the bubbles finally accumulate in the absorption tube and attenuation tube, it will affect the measurement. the accuracy of

The invention discloses a long-term automatic measurement device and method for hyperspectral water body absorption attenuation. The device comprises a hyperspectral water absorption attenuation measuring instrument, a sample chamber, a seawater filter and a purified water storage tank. A water sample outlet of the sample chamber is connected with a first three-way pipe, the first three-way pipe is connected with a second three-way pipe and a third three-way pipe, and the second three-way pipe is connected with a fourth three-way pipe and a first outlet; the third three-way pipe is connected with a fifth three-way pipe and a second outlet; the fourth three-way pipe is connected with an outlet of a seawater filter and a lower opening of an A pipe of a measuring instrument. The fifth three-way pipe is connected with the purified water storage tank and a lower opening of a C pipe of the measuring instrument. An upper opening of the pipe A is connected with an opening A of the sample chamber, an upper opening of the pipe C is connected with an opening C of the sample chamber, and the opening A and the opening C are connected with two inlets of a two-in one-out one-way valve in the sample chamber; and the other outlet of a sixth three-way pipe is connected with a water sample inlet of the sample chamber. According to the device and the method disclosed by the invention, bubbles canbe prevented from gathering in the measuring instrument, automatic cleaning can be realized, and the measuring effect is ensured.
Description
technical field [0001] The invention relates to the technical field of marine monitoring instruments, in particular to a long-term automatic measurement device and method for hyperspectral water body absorption attenuation. Background technique [0002] The hyperspectral water absorption and attenuation measuring instrument (AC-S) is currently the main instrument for in-situ measurement of water absorption and attenuation coefficients in the world. The traditional method of using the AC-S instrument is to use the mooring method, that is, to place the entire instrument in seawater. However, this method must be operated manually and cannot be used online for a long time. In recent years, water sample supply methods have appeared on buoys, shore stations, and scientific research ships, that is, AC-S is carried on an offshore platform or ship, and water samples are taken through the water supply and drainage system and sent to the instrument, and the water samples are discharged...
