Technical Field
The invention relates to the technical field of ships, in particular to a rudder propeller device with a tail vane.
Background
Due to the operation requirement, offshore engineering ships such as measuring ships and submarine cable ships often need to carry out measurement or cable laying operation along a fixed route, and in order to resist the influence of external environmental forces such as stormy waves and currents, dynamic positioning systems are generally configured. To achieve good dynamic positioning performance, a full-turn rudder propeller is often used as a propeller of the dynamic positioning system. However, the rudder propeller device swings left and right at a small angle in unstable water flow; in addition, in order to ensure that the rudder propeller rotates by 360 degrees and meet the requirement of sufficient incoming flow at the position of the rudder propeller, a large part of the tail hull is often cut off, so that the side projection area of the hull is small and the center of the hull is deviated, the phenomena of leftward and rightward swinging of a ship and poor course stability occur during free navigation or towing dispatching and operation, and the energy consumption and the operation efficiency of a host are adversely affected.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
Referring to fig. 1-2, the present invention provides a structure diagram of a rudder propeller device with a tail vane, including: the device comprises a driving mechanism 1, a driving shaft 2, a propeller 3, a guide pipe 4 and a tail vane 5, wherein the driving mechanism 1 is fixedly arranged on a ship body 6; the driving shaft 2 is arranged in the driving mechanism 1 and is connected with the propeller 3; the conduit 4 is fixedly connected with the driving mechanism 1; the tail vane 5 is arranged at the center line behind the conduit 4.
Specifically, a streamlined tail blade 5 is arranged at the center line behind the conduit 4, and the side projection center of the rudder propeller device is moved backwards, so that the rudder propeller which often swings under the disturbance of water flow tends to be stable. In addition, the tail vane 5 also increases the side projection area of the stern body 6, and moves the side area center backwards, so that the course stability of the ship in free sailing, towing and dispatching or operation states can be improved.
Further, one end of the driving shaft 2 is fixedly connected with the ship body 6, and the other end of the driving shaft 2 is connected with the propeller 3.
Further, the propeller 3 is installed inside the duct 4.
Further, the tail vane 5 includes at least a first tail vane and a second tail vane, and the first tail vane and the second tail vane are respectively disposed at two sides of the central line behind the conduit 4.
Referring to fig. 3, which is a plan view of a specific embodiment of the rudder propeller device with the tail blades 5 provided by the present invention, the tail blades 5 are respectively arranged on two sides of a center line behind the conduit 4, and by adding the tail blades 5, a side projection center of the rudder propeller device is moved backward, so that the rudder propeller which often swings under the disturbance of water flow tends to be stable. In addition, the tail vane 5 also increases the side projection area of the stern body 6, and moves the side area center backwards, so that the course stability of the ship in free sailing, towing and dispatching or operation states can be improved.
Further, the tail vane 5 is connected with the guide pipe 4 by welding.
Specifically, the tail vane 5 is directly welded at the rear end of the guide pipe 4, the water flow in front of the guide pipe 4 and the whole guide pipe 4 are not influenced, so that the thrust generated by the guide pipe 4 is not influenced, and the tail vane 5 is directly connected with the guide pipe 4 and can rotate along with the rudder propeller, so that the rudder propeller serving as a propeller of a ship dynamic positioning system is not influenced.
Further, the thickness of the tail vane 5 is a predetermined thickness, and the length of the tail vane 5 can extend to the vicinity of the stern vertical line.
Specifically, the tail vane 5 can be directly welded on the outer side or the inner side of the guide pipe 4, the shape of the tail vane 5 is an NACA airfoil shape, the thickness is as small as possible, the requirement on strength is met, and the length can be extended to the position near a stern vertical line at most. The vertical line of the stern is the intersection point of the rear edge of the stern sealing plate and the summer full waterline and is perpendicular to the base line. The tail vane 5 is directly connected with the guide pipe 4, so that the structure is very simple, an additional driving mechanism 1 is not needed, and the operation of the steering oar is facilitated.
Further, the tail vane 5 is a streamlined tail vane.
Specifically, the tail vane 5 is small in thickness, and the tail vane 5 is a streamline tail vane, so that the influence on the water flow is small, and no obvious additional resistance is generated.
