Middle drag plate type tail vane device of catamaran

Abstract

The invention discloses a middle drag plate type tail vane device of a catamaran. A part of the tail vane device consists of a motor, a screw rod, a middle drag plate, a crank, a bolt, a bearing and a bracket, wherein the part is arranged on a catamaran body by the motor at one end of the screw rod and the bracket at the other end of the screw rod, the middle drag plate is sheathed on the screw rod, and the crank is arranged on the middle drag plate; the other part of the tail vane device consists of a tail vane shaft, a tail vane and a T-shaped groove crossbeam platform, the tail vane is fastened on the tail vane shaft and is arranged on the T-shaped groove crossbeam platform by the tail vane shaft, and the top end of the tail vane shaft is a square rod section; the screw rod is embedded in a T-shaped groove of the T-shaped groove crossbeam platform by a groove structure in the middle drag plate, and a connecting rod is sheathed on a boss of the crank and the square rod section so as to connect the square rod section and the crank together; and the middle drag plate moves horizontally due to the rotation of the screw rod with the power provided by the motor, and the crank and the connecting rod drive the tail vane shaft to rotate so as to drive the tail vane to rotate. According to the middle drag plate type tail vane device, a screw rod-crank-connecting rod mechanism can control the turning of a rudder, the tail vane can be controlled conveniently, and the basis is provided for the remote control.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of ship parts, in particular to a mid-trailer rudder device of a catamaran, which is used to control the navigation of the catamaran. Background technique [0002] The tail rudder device relevant to the present invention mostly adopts the form of "rudder plus steering gear" at present, and its design idea is: the power and the tail rudder device are separated from the rudder, or are supplemented with propellers for assistance. There is also a twist-type horizontal rudder design, and its working method is to rely on the steering gear and the propeller to provide power to make the rudder swing and change direction and propel the hull. At present, this kind of torsional transverse rudder is still relatively rare, and it is mainly designed for special purposes and requires relatively large power. [0003] The above-mentioned rudder needs a large power because it needs to be equipped wi...
