Unmanned ship device and sample reserving method for automatic water sample reserving

Abstract

The invention relates to an unmanned ship device and a sample reserving method for automatic water sample reserving. The unmanned ship device comprises an unmanned ship main body, an energy and control unit and an automatic water sample reserving unit arranged in a cabin of the unmanned ship main body and a water multi-parameter monitoring probe arranged on the lower side of the unmanned ship mainbody. The water multi-parameter monitoring probe transmits water parameter data to the energy and control unit through a transmission cable; the automatic water sample reserving unit comprises a sampling bottle, a supporting body mechanism provided with the sampling bottle, a sampling pump arranged on the outer side of the unmanned ship main body, a sampling hose connected to the sampling pump and a swing arm water taking mechanism which controls the sampling hose to rotate. The unmanned ship device has the monitoring and sample reserving functions at the same time, triggers sampling by online monitoring data and preset conditions, and is immediate to reserve samples; the reserved samples are highly consistent to online monitoring objects, so that the follow-up application and analysis application are improved.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an unmanned ship device and a method for automatically retaining water quality samples. Background technique [0002] In the field of water environment monitoring, when performing online monitoring of surface water bodies such as rivers, lakes, reservoirs, and coastal waters, the traditional online water quality monitoring system is generally located at a fixed monitoring site, and can only monitor water quality at a certain point, which can only represent a fixed point. Water quality conditions within a limited range, but to obtain water quality conditions in different regions, multiple monitoring stations need to be arranged, which has high investment costs, long construction period, difficult maintenance, high operating costs, inability to flexibly move according to needs, and inability to freely adjust water samples There are shortcomings such as monitoring depth, and ...

AI Technical Summary

Problems solved by technology

When the movable online monitoring probe measures the water quality status, according to the water quality risk status that the monitoring application is concerned about, once it is found that the current water quality status needs in-depth analysis, it is required to keep water quality samples in time. The conventional mobile monitoring system does not have monitoring and sample retention at the same time. capacity, if the corresponding water quality samples are not retained, follow-up in-depth analysis cannot be carried out, and data application and decision-making will also lack convincing

If artificial or other systems are used independently to retain samples in addition to the mobile online monitoring system, there will be problems of time delay and sampling location differences, resulting in inconsistencies between the retained water samples and the online data, reducing the value of subsequent application analysis
