Floating and steering integrated device for small submersible

Abstract

The invention relates to an upward-floating and steering integrated device for a small submersible. The upward-floating and steering integrated device comprises a water tank, a supporting board, a piston water tank, a water inflow pipeline, two outlet pipelines, a communicating pipeline, a gear steering mechanism, an injection pump, a main butt joint device, two auxiliary butt joint devices, two electromagnetic valves, a left pipe, a right pipe, a front pipe and a rear pipe. The gear steering mechanism is adopted for combining a steering mechanism and an upward-floating mechanism into a whole, and rapid switching of upward-floating and steering is achieved. Thrust generated by water sprayed from the insides of the pipelines is used for replacing thrust generated by a propeller, and horizontal steering and rapid upward-floating of the small submersible are achieved. The flow is controlled through the electromagnetic valves, under the condition that the advancing condition of the small submersible is not affected, upward-floating avoidance can be achieved according to the size of an obstacle, the technical performance is good, work is reliable, manufacturing, installation and maintenance are easy, the small submersible can avoid the obstacle in time when encountering the obstacle and can float upwards rapidly as well under an emergency, and the underwater operation safety of the small submersible is improved.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a floating and steering integrated device for a small submersible, which can realize the floating and steering of the small submersible. Background technique [0002] At present, most small submersibles use steering propellers to realize the steering function, and the floating function is mostly realized by discharging the seawater in the submersible. The influence of external forces will have a certain impact on its underwater operation, so how to make the layout and integration of small submersibles as reasonable as possible within a limited volume is particularly important. [0003] The Chinese invention patent application with the publication number CN 103963952 A discloses a steering propulsion system for a small submersible, which includes a steering mechanism and a propulsion mechanism arranged on the upper and lower layers of the system, and is connec...
