Abstract

The invention discloses an underwater helicopter with a propeller structure, and belongs to the technical field of underwater delivery. The main composition comprises a dish-shaped hull, a pair of vector propellers, and a pair of propeller structures. The propeller structures can extend to the outside of the dish-shaped hull from the inside of the dish-shaped hull in working, and after working iscompleted, the dish-shaped hull is recovered, and the propeller structures can change the angle between the paddles and the XY plane in a certain scope. According to the underwater helicopter with a propeller structure, due to the unique paddle structure design, the capacity of separating from the ocean current of the underwater helicopter can be effectively improved, and meanwhile, the overall energy consumption can be reduced, so that the underwater helicopter obtain more excellent movement performance and more lasting cruising power.

Description

technical field [0001] The invention relates to the technical field of underwater transportation, in particular to an underwater helicopter with a propeller structure. Background technique [0002] At present, traditional unmanned submersibles are basically suitable for observation and operation of the upper water body of the ocean. They avoid approaching the seabed due to various reasons such as danger, while underwater helicopters can conduct observation and operations near the seabed for a long time. Moreover, the buoyancy adjustment of the existing unmanned submersibles is slow and cannot meet the needs of rapid response. [0003] The new concept "underwater helicopter" based on new principles and new technologies is to develop a flexible submarine-to-submarine working mode around key scientific issues such as improving the maneuverability of the submersible and enriching the working mode of the submersible. New type of submersible. It can realize fixed-point hovering,...
