AI Technical Summary
Existing water samplers are susceptible to external contamination during the sampling process, have no adjustable rinsing depth, insufficient depth control precision, complex sealing structures, and insufficient reliability under high pressure, making it difficult to obtain absolutely clean seawater samples.
A depth-triggered interlocking water sampler is designed, employing a deck locking component, a cover-opening energy storage element, a water pressure unlocking component, and a CTD electrical signal triggering component. The opening and closing of the end cover is controlled by water pressure and electrical signals to achieve adjustable depth flushing and precise sealing. A high-pressure resistant sealing ring is used to ensure sealing performance.
It achieves clean sampling of water samples, with adjustable rinsing depth, precise depth control, and reliable sealing. It is suitable for marine scientific research and marine environmental monitoring, and can meet the needs of seawater trace element collection in different sea areas.
