Manipulating device of retractable bow rudder

Abstract

The invention discloses a manipulating device of a retractable bow rudder. The manipulating device comprises a steering device, a left rudder retracting device and a right rudder retracting device, the steering device comprises a steering engine, a steering rocker arm, a rotation shaft, a transition rocker arm, a connecting rod, a steering shaft rocker arm, a steering shaft, a left sliding seat, aleft arc-shaped guide rail, a right sliding seat and a right arc-shaped guide rail, and the steering engine is connected with the steering rocker arm. The transition rocker arm is connected with thesteering rocker arm through the rotation shaft. The two ends of the connecting rod are hinged to the transition rocker arm and the steering shaft rocker arm correspondingly, the steering shaft rockerarm is arranged in the middle of the steering shaft and fixedly connected with the steering shaft, and the left sliding seat and the right sliding seat are arranged at the two ends of the steering shaft correspondingly. The left arc-shaped guide rail and the right arc-shaped guide rail are symmetrically arranged, the left rudder retracting device and the right rudder retracting device are connected with the steering device through the left sliding seat and the right sliding seat correspondingly and can rotate by 90 degrees around the left arc-shaped guide rail and the right arc-shaped guide rail. By adoption of multi-mechanism intersection design, the relation of the connecting rod and the rocker arms of mechanisms is optimized in a limited space, and the overall manipulating performance of an underwater vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of underwater submersibles, in particular to a retractable bow rudder control device. Background technique [0002] The bow rudder is located at the head of the submersible, and can be divided into two types: fixed and retractable. The fixed type is similar to the casing rudder of the active model; the retractable device is more complicated. If the rudder is damaged, it can be designed to be foldable and arranged in the superstructure space above the bow load waterline with a larger aspect ratio. The reason for setting the bow horizontal rudder is that it can independently control the trim and dive depth, especially in the emergency situation where the stern rudder jams, the advantage of the bow rudder is more obvious. However, the bow rudder also has obvious defects. Due to the small effective space of the bow, the collapsible bow rudder is prone to conflict with other equipment in the arrangement. Domest...

Problems solved by technology

However, the bow rudder also has obvious defects. Due to the small effective space of the bow, the collapsible bow rudder is prone to conflict with other equipment in the arrangement.

Domestic research on the bow rudder device is less, and due to the less application in the active models, the research on the device is relatively backward, and the design experience is lacking, so it is urgent to carry out research on this technology
