Abstract

The invention relates to fully rotary type underwater propellers. Each fully rotary type underwater propeller is composed of a propulsion mechanism, a horizontal steering mechanism, a vertical steering mechanism and an electronic element set; under the action of the horizontal steering mechanism and the vertical steering mechanism, the propulsion mechanism can rotate around the Y axis and the Z axis; the situation that internal cables are wound due to relative rotation between the components is avoided, and thus the propulsion mechanism can rotate at any angle around the Y axis and the Z axis and can continuously rotate by multiple circles; the rotation angles of the propulsion mechanism around the Y axis and the Z axis can be determined by detecting output signals of a horizontal steering shaft position detecting device and a vertical steering shaft position detecting device; and a second sealed cabin is provided with at least one watertight plug connector, and the watertight plug connectors can conduct electric power and signal transmission with submersibles or the outside and can also achieve collaborative operation among the multiple fully rotary type underwater propellers. The fully rotary type underwater propellers are high in flexibility and compact in structure, and the modular design of the submersibles is beneficially achieved.

Description

technical field [0001] The invention belongs to the technical field of underwater equipment, in particular to a fully rotary underwater propeller. Background technique [0002] For underwater sports equipment such as submersibles, underwater propellers are an important part of them. In the existing technology, the fixed propeller can only provide thrust in a single direction. In order to realize the controllability and flexibility of the submersible’s movement, it is necessary to arrange multiple fixed propellers in different directions, or to combine fixed propellers. Propellers and rudders lead to complex structures and bulky submersibles. The use of vector propulsion technology can improve the controllability and flexibility of the submersible. [0003] In the Chinese invention patent application publication specification CN101941517A, a swing type propeller is disclosed. This swing type propeller drives the gear through the rack, so that the direction of the propeller ...
