Description

Technical Field

[0001] The utility model relates to the technical field of unmanned ships, in particular to a hull structure of an unmanned ship. Background Art

[0002] Water environment monitoring is to use physical, chemical and biological techniques to conduct qualitative, quantitative and systematic comprehensive analysis of pollutants and their related components in the water environment, so as to explore and study the changing laws of water environment quality. Water environment monitoring provides reliable basic data for water environment management and provides a scientific basis for the evaluation of the effectiveness of governance measures. In order to enable the monitoring data to accurately reflect the current quality of the water environment and predict the development trend of water environment pollution, the water environment monitoring data should be representative, accurate, precise, parallel, repeatable, complete and comparable. An unmanned ship is a ship that does not require human control. It is usually composed of an autonomous navigation system, sensors, control system and power system, and can autonomously complete functions such as navigation, mission execution and environmental perception.

[0003] Existing unmanned boats are vulnerable to wind and waves, which may cause the unmanned boats to tilt severely or even capsize, resulting in damage to water quality testing equipment. Utility Model Content
