Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, and in particular to a deep sampling unmanned boat with a sampling water inlet control structure. Background Art

[0002] With the continuous development of science and technology, the management of water resources has also increased. Management is carried out in various aspects, such as some inspection sampling research. At present, the inspection efficiency of manual inspection of reservoirs is low. The existing water quality monitoring forms mainly include manual sampling, fixed buoy point sampling and mobile sampling. Most of the reservoir sampling adopts manual sampling. The water quality is taken back to the laboratory through sampling, and various factors are independently analyzed by high-precision instruments to obtain high-precision analysis reports. However, this process is difficult to meet the monitoring timeliness requirements for waters with sudden pollution or frequent water quality changes. With the development of wireless monitoring technology and photovoltaic cells, in some waters with relatively small water surface fluctuations, water quality can be monitored in real time through fixed buoy base stations, which solves the timeliness problem in manual sampling. However, for large-scale reservoir waters, the number of monitoring nodes requires a large investment, and there are some parts that are far away from the central node and difficult to be monitored by automatic monitoring equipment. At the same time, for reservoirs with a depth of tens of meters, manual sampling is difficult to reach a certain depth, and it is impossible to monitor the water quality data of deep water.

[0003] In order to reduce the number of people operating and avoid the potential safety hazards caused by manual collection, the use of unmanned boats for deep-water collection is being studied. The fixed buoy monitoring method is not suitable for scenarios where the water quality fluctuates greatly over time, and frequent layout adjustments increase the cost of monitoring points. Unmanned boats, with their unique maneuverability, have solved the problem of difficulty in obtaining water. At the same time, the samples collected by boats cannot carry a lot, and the pipes deep underwater cannot be guaranteed to be stable and vertical. The pipeline transportation process is prone to abnormal problems such as slipping and staggering. Summary of the invention
