Description

Technical Field

[0001] This utility model belongs to the field of unmanned surface vessel technology for oil spill recovery, and in particular relates to an unmanned surface vessel for monitoring and recovering oil spills on water. Background Technology

[0002] Oil spills refer to the leakage of crude oil or oil products from the work site or storage tank due to accidents or operational errors during the exploration, development, refining, transportation, and storage of oil. By using unmanned surface vessels (USVs) for oil spill monitoring and recovery, the floating oil on the sea surface can be intercepted, recovered, and treated, thereby reducing subsequent economic and environmental damage. USVs for oil spill monitoring and recovery (also known as oil spill recovery USVs or oil pollution monitoring USVs) are innovative surface cleaning equipment that combines unmanned driving technology, sensor technology, and automated recovery technology.

[0003] For example, China's utility model patent number 202320987112.5 provides a "multi-functional unmanned boat for oil spill recovery". This patent includes a boat body with a recovery port on the side of the boat body. The inner wall of the recovery port has a slot, and a filter screen is slidably installed inside the slot. A handle is connected to the top of the filter screen. By rotating the knob, the baffle is rotated, and the filter screen can be pulled out through the handle for cleaning or replacement, which improves the work efficiency of the staff.

[0004] While the aforementioned documents address the issue that existing unmanned oil spill recovery vessels (UAVs) may contain a large amount of debris during oil spill interception, recovery, and treatment, and that this debris could damage internal components of the vessel, they still suffer from the drawback of lacking efficient monitoring capabilities. The UAVs are not equipped with high-precision oil spill detection structures, preventing them from autonomously monitoring and locating oil spills. Therefore, this paper introduces a new type of unmanned vessel for waterborne oil spill monitoring and recovery. Utility Model Content

[0034] The working principle of this utility model is as follows: First, the oil spill monitoring unmanned vessel is placed in a designated water area. Under the operation of the staff at the shore control center, the unmanned vessel travels on the water surface. As the unmanned vessel travels in the designated water area, the oil spill detection sensor 18 detects the water area it passes through as the vessel 1 travels on the water surface. The oil spill detection sensor 18 can accurately detect the slight changes in the oil layer on the water surface, thereby realizing early leakage alarm. The abnormal information is transmitted back to the shore control center in real time through the wireless transmission module in the control box 12. The staff remotely controls the unmanned vessel and turns on the water pump 23. The water pump 23 pumps the water containing oil into the separation tank 13 through the water inlet pipe 20 on one side of the connecting shell 19. The inner cavity of the separation tank 13 is equipped with a separation membrane 15. The material of the separation membrane 15 is an electrospun nanofiber membrane.
