Abstract

The invention discloses a rudder system structure of a surface ship. In short, the invention improves the prior art that a rudder blade is arranged right behind the propeller into a rudder blade is arranged behind each of two sides of the propeller. The invention can inhibit the left and right or circumferential diffusion of the back-rotating water flow of the propeller, improve the propelling efficiency and achieve the energy-saving effect. The technical scheme is as follows: a steering system structure of a water surface ship is provided with a steering device comprising a steering engine, a steering mechanism, a steering system and the like, wherein a power system is arranged in a ship body of the water surface ship and connected with a stern shaft, and the stern shaft penetrates through a stern board and is connected with a propeller; and a rudder blade vertical to the horizontal plane is respectively arranged behind two sides of the propeller.

Description

Rudder system structure of water surface ship

1. Field of the invention

The invention relates to the field of water surface transportation operation, in particular to a rudder system structure of a water surface ship.

2. Background of the invention

The setting of the surface of water boats and ships that adopt propeller propulsion at present generally is: a power system is arranged in the ship body and connected with a stern shaft, and the stern shaft penetrates through a stern board and is connected with a propeller. The ship has the advantages of simple structure, easy maintenance and the like, is adopted by most of water surface ships, particularly large and medium ships at present, and the stern rudders are generally arranged right behind propellers of the ships so as to improve the maneuverability of the ships; however, such an arrangement has disadvantages: the water flow discharged by the propeller backwards rotates backwards and is approximately conical, and the stern rudder is arranged in the middle of the backward rotation water flow of the propeller, so that the backward rotation water flow can be interfered, the circumferential diffusion of the backward rotation water flow is aggravated, and the propulsion efficiency is reduced. While the ship usually does not need to be steered frequently during navigation, a stern rudder arranged right behind a propeller continuously disturbs the backward whirling water flow.

3. Summary of the invention

The purpose of the present invention is to improve the economy and maneuverability of a surface vessel.

The technical scheme of the invention is as follows: the utility model provides a surface of water boats and ships's rudder system structure, surface of water boats and ships be equipped with and handle the device including steering wheel, steering mechanism and rudder system etc. surface of water boats and ships hull in be equipped with driving system and connect the stern axle, the stern axle pass stern board and connect the screw, the screw both sides after respectively establish the rudder blade of a perpendicular to horizontal plane.

The steering engine controls the two rudder blades through a rudder steering mechanism, and the direction of water flow is interfered by the two rudder blades.

The invention has the advantages of

The invention avoids the interference of a rudder blade arranged right behind the propeller on the back-rotating water flow of the propeller; in a water flow channel formed by the double rudder blades, the left-right or circumferential diffusion of the backspin water flow of the propeller can be inhibited. In conclusion, the beneficial effects of the invention are as follows: 1. the propulsion efficiency can be improved to achieve the energy-saving effect; 2. the maneuverability of the ship can be improved.

4. Description of the drawings

FIG. 1 is a schematic top view of the embodiment

FIG. 2 is a schematic top view of the second embodiment

5. Detailed description of the preferred embodiments

See the drawings. In the figure, 1, a stern board, 2, a stern shaft, 3, a propeller, 4, a rudder stock, 5, a left rudder blade, 6, a transmission rod, 7, a right rudder blade, 8, propeller backward rotation water flow, 9, propeller backward rotation water flow after the two rudder blades are dry, and 10, an upper flow limiting plate.

The first embodiment is as follows: referring to the attached figure 1, a container ship is provided with a steering device comprising a steering engine, a steering mechanism, a steering system and the like, wherein a power system is arranged in a ship body and connected with a stern shaft, the stern shaft penetrates through a stern board to be connected with a propeller, two rudder blades which are vertical to a horizontal plane and have the same shape are respectively arranged behind two sides of the propeller, and a transmission rod is arranged between the left rudder blade and the right rudder blade and is parallel to the left rudder blade and the right rudder blade.

The propeller is not interfered by a rudder blade, and the backward rotary water flow is generally approximately conical; the two rudder blades are arranged outside the approximate cone formed by the backspin water flow of the propeller close to the propeller part, and the two rudder blades are arranged inside the approximate cone far away from the propeller part.

And controlling the two rudder blades to control the course of the container ship: the steering engine drives the rudder stock to rotate the left rudder blade, and simultaneously drives the right rudder blade to rotate in the same direction through the left rudder blade and the transmission rod. (the rudder blade arranged on the left side of the propeller is a left rudder blade and the rudder blade arranged on the right side of the propeller is a right rudder blade when the propeller is seen from the stern forwards.)

Example two: referring to the attached figure 2, the bulk cargo ship is provided with a steering device comprising a steering engine, a steering mechanism, a steering system and the like, wherein a power system is arranged in a ship body and connected with a stern shaft, the stern shaft penetrates through a stern board to be connected with a propeller, rudder blades which are vertical to a horizontal plane and have the same shape are respectively arranged behind two sides of the propeller, a transmission rod is arranged between the left rudder blade and the right rudder blade and are parallel to each other, and a flow limiting plate which is parallel to the horizontal plane is arranged above and below the left rudder blade and the right rudder blade.

The rudder blade and the flow limiting plate form an approximate square pipe; the approximate square tube can inhibit circumferential diffusion of the back-swirling water flow of the propeller.
