[0002] At present, industrial wastewater, domestic sewage and other waste enter the sea, seriously damaging the ecological environment, so the detection and analysis of the heavy metal content in seawater is particularly important. Marine environment heavy metal pollution monitoring is a key link for assessing marine ecological risk and protecting human health. The monitoring objects mainly include typical heavy metals such as lead, mercury, cadmium, chromium and copper. These substances enter the ocean through industrial wastewater, agricultural non-point sources and atmospheric deposition, and can be enriched through the food chain to cause long-term harm to the ecological system and human health. Monitoring technology covers traditional chemical analysis and emerging artificial intelligence applications, forming a complete system from sample collection to data interpretation. In the current detection process, a heavy metal monitor is generally used to achieve the detection. A marine environment heavy metal pollution monitoring equipment (CN222318922U) is disclosed in a Chinese patent. After the electric push rod 16 performs the water pumping action, the seawater fills the sample chamber 17, and the analysis collection head of the water sample heavy metal monitor 15 directly contacts the sample seawater to perform analysis. The current monitoring equipment cannot adjust the depth of seawater collection according to the actual detection requirements in the actual detection process, which causes the collection head to detect at the same position for a long time, resulting in that the accuracy of the detection cannot be guaranteed. In the sampling and detection process, the traditional sampling method is pumping, which can easily destroy the balance of the internal components of the water sample under the action of the pumping pressure, resulting in differences between the monitoring results and the actual pollution situation.
