Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] The method of the present invention is to place the stern rudder blades at a position perpendicular to the water flow, thereby generating huge braking resistance, so that the ship brakes and decelerates quickly. The ground rotates 90° to a position perpendicular to the water flow to become a brake baffle, thereby realizing braking deceleration; the method of the present invention is realized by using an emergency brake steering device, and its control system is composed of an emergency brake steering device, an executive The movement direction control unit of the mechanism, the actuator, and the rudder angle transmitter form a closed-loop control system to control the rotation of the rudder blade. The rudder angle transmitter has a feedback loop connected to the emergency braking steering device. When the blade is not at the zero rudder angle position, the rudder ang...

Abstract

A method for brkaing ship by rudder features that the rudder installed at stern is controlled to make it perpendicular to water stream, so generating huge braking resistance to quickly decelerate it.

Description

technical field [0001] The invention relates to a method for braking and decelerating a ship, in particular to a method for braking and decelerating a ship by using rudder blades Background technique [0002] In recent years, my country's inland river vessel marine accidents have occurred frequently and are on an accelerated upward trend. Hundreds of major accidents occur every year, and hundreds of ships sink, causing a large number of casualties, direct economic losses of hundreds of millions of yuan, and huge losses to the country and people's lives and properties. loss. Therefore, it is imminent to take targeted measures to solve the safety problems of ship navigation. Ships sailing in inland rivers are like cars driving on roads. It is not difficult to imagine the consequences if the brakes of cars fail to work. However, for a long time, the problem of "brakes" of ships has not attracted enough attention. In various editions of the "Ship Maneuvera...
