Abstract
The utility model discloses a kind of hydrology rudder for ship paddle composite structures, including two propellers, it is characterized by: described two propellers are separately positioned in two shallow tunnels, the tunnel top depth D/d=1.10 in the shallow tunnel, tunnel top line is gradually curved to two sides, twin shaft spacing b/B=1.3/3=0.433；Further include having rudder blade, a flowing plate processed is respectively equipped with above and below the rudder blade；By the way that two propellers are separately positioned on two shallow tunnels, tunnel top line is gradually curved the rudder paddle composite structure to two sides, is conducive to shallow water water suction, the stability of hull is improved, in addition, flowing plate processed is all arranged above and below rudder blade, it can be improved steerage, facilitate operation.
Description
Technical field
The utility model relates to technical field of ships, in particular to the rudder paddle composite structure of a kind of hydrology ship.
Background technique
Huanghe water is shallow, water flow is anxious, silt is big, and how the Yellow River ship guarantees ship performance, is one such as the speed of a ship or plane, maneuverability
Crucial technical problem.
Hydrology ship be for hydrologic monitoring, it is very high to the stability requirement of ship itself during monitoring, and show
The design of some hydrology rudder for ship paddles is unreasonable, and stability is poor when leading to encounter the hydrological environment that water flow is big, silt is big, is difficult to operate.
Utility model content
It is poor in order to solve existing hydrology ship stability, it is not easy to which that the problem of operating, the utility model provide a kind of stabilization
Good, the maneuverable hydrology rudder for ship paddle composite structure of property.
To achieve the goals above, technical solution provided by the utility model is: a kind of hydrology rudder for ship paddle composite structure, packet
Two propellers are included, described two propellers are separately positioned in two shallow tunnels, the tunnel top depth D/d=in the shallow tunnel
1.10, tunnel top line is gradually curved to two sides, twin shaft spacing b/B=1.3/3=0.433；It further include having rudder blade, on the rudder blade
Just and it is respectively arranged below with a flowing plate processed.
As a kind of preferred technical solution, the propeller is five vane propellers.
In the above-mentioned technical solutions, further, the platter surface ratio of the propeller is 0.7.
Damping cave is equipped with above the propeller as a preferred technical solution,.
The propeller is arranged on A-frame as a preferred technical solution, and the A-frame is using asymmetric herringbone
Frame setting.
Further, the rudder exhibition side of a ship ratio of the hydrology ship is 0.574.
In the above-mentioned technical solutions, the area of rudder coefficient of the hydrology ship is 7%.
The beneficial effect of the utility model compared with the existing technology is: the rudder paddle composite structure is by dividing two propellers
It She Zhi not be gradually curved in two shallow tunnels, tunnel top line to two sides, be conducive to shallow water water suction, improve the stability of hull,
In addition, flowing plate processed is all arranged above and below rudder blade, it can be improved steerage, facilitate operation.
Detailed description of the invention
Fig. 1 is the propeller distribution map of the utility model；
Fig. 2 is the cross-sectional view in the face A-A in Fig. 1；
Fig. 3 is the cross-sectional view in the face B-B in Fig. 2.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1-3, a kind of hydrology rudder for ship paddle composite structure, hull 1, at the rear of hull 1, there are two spirals for setting
Paddle 2, in the present embodiment, propeller 2 use five vane propellers, and the platter surface ratio of propeller 2 is 0.7, can prevent vibration and
Vacuole occurs, and the stability of hull is improved while can reduce noise.
Two propellers 2 are separately positioned in two shallow tunnels 3, and propeller 2 is arranged on A-frame 4, and A-frame 4 uses
Asymmetric A-frame setting.Using asymmetric A-frame, flat stern middle line on propeller is distorted to the left to reduce on the left of waterline
Angle of exit, in front of paddle upper left hull surface along waterline towards longitudinal gradient in tail direction also reduce thus, point in the region
Weaken from flowing, Disengagement zone diminution, reduces energy consumption, to reduce Ship Resistance.
In addition, asymmetric A-frame successfully improves the forward and backward flow field of paddle with its distorted shape, ship resistance is reduced
Power, wake flow rotating energy loses after having recycled part ship；Simultaneously as the anti-paddle efficiency of generation acquisition of preswirl makes spiral shell before its paddle
It revolves paddle propulsive efficiency to improve, achieves preferable energy-saving effect.
The tunnel top depth D/d=1.10 in shallow tunnel 3, tunnel top line are gradually curved to two sides, twin shaft spacing b/B=1.3/3
=0.433；Damping cave 7 is equipped with above propeller 2, damping cave 7 can improve the stability of hull into hull vibration is reduced.
A flowing plate 6 processed is respectively arranged below with above rudder for ship design aspect, rudder blade 5, it is 0.574 that rudder, which opens up side of a ship ratio, rudder face
Product coefficient is 7%, which can be improved steerage, facilitate operation.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
