Description

River and lake patrol ship

Technical Field

Background

The river and lake inspection boat is a boat suitable for short-term navigation in river and lake water areas, and is mainly used for daily river inspection, supervision, comprehensive command and the like.

The existing patrol ship steering mode mainly realizes steering by pushing water flow through a propeller and combining steering of a rudder, and the principle of the current patrol ship steering mode is that under the driving of the propeller, the flow velocity of the water flow on two sides of the rudder generates a difference value, the flow velocity of the water flow side of the rudder is slower than that of the water flow side, so that the pressure on the water flow side of the rudder is increased, the pressure on the water flow side of the rudder is reduced, and steering of a ship body is realized under the action of pressure difference.

However, in the conventional ship with a single rudder design, the flow lines around the rudder blades are separated from the rear edge of the rudder blades, so that eddy currents are generated, the rudder force is rapidly reduced, when the phenomenon occurs, the corresponding rudder angle is the limit rudder angle, and when the rudder of the ship is turned over to exceed the limit rudder angle, the rudder force is reduced, and the ship is easy to turn on one side.

The extreme rudder angle and the size of rudder blade aspect ratio are in an inverse proportion relation, for inland river ships, the extreme rudder angle of the single steering rudder is about thirty-five degrees due to the fact that the rudder blade aspect ratio is mostly set to be one, the ship body needs a large rotating distance in the process of steering, and safe steering is difficult to achieve for river channels with small widths.
