Description

Hydrodynamic layout full-rotation rudder propeller
Technical Field
The utility model relates to a boats and ships power equipment especially relates to a hydrodynamic force overall arrangement rudder oar that turns around entirely.
Background
The existing steering oar mainly ensures the navigation speed and low-speed operation performance, but neglects the unfavorable hydrodynamics performance of the steering oar due to the cancellation of a conventional rudder blade. The stability of the ship is reduced due to the fact that the underwater side projection area of the tail of the ship is reduced after the rudder blade is not arranged. In addition, the conventional rudder blade utilizes relatively high-speed water flow to generate a rudder effect, so that the conventional rudder blade ship can fully utilize the flow speed to generate a certain rudder effect in a rapid navigation section, the rudder effect can be very good also on a high-speed ship, but the rudder effect on a low-speed ship is very poor. The steering of the steering oar changes the thrust direction of the propeller to generate the steering effect, so that the thrust in the advancing direction can be reduced when the steering effect is generated, and particularly the steering of the large steering oar is more obvious, so that the ship can not advance due to the reduction of the thrust in the advancing direction in the torrent navigation section, so that the steering oar is not very suitable for the torrent navigation section and is also not very suitable for a high-speed ship, so that the existing modeling steering oar is generally applied to a large number of low-speed ships in an inland river flat still water area or on the sea, but is not very successful in the torrent navigation section and is also very few in the high-speed ship; in a word, the conventional rudder blade has the characteristic that the rudder effect is very good when the incoming flow speed is high, the rudder effect is very good when the incoming flow speed is low, and the steering effects of the two devices are just opposite.
SUMMERY OF THE UTILITY MODEL
The applicant aims at the defects and carries out research and improvement to provide a hydrodynamic layout full-turning rudder propeller.
The utility model discloses the technical scheme who adopts as follows:
the utility model provides a hydrodynamic force overall arrangement rudder oar that turns around entirely, includes the installation grillage, connect upper gear box and lubricating-oil tank on the installation grillage, installation grillage lower extreme rotates and connects rotation mechanism, rotation mechanism includes that the rudder blade shape goes up pillar and lower gear box, the screw is connected to the gear box down, the screw passes rotation mechanism and installation grillage through drive mechanism and is connected with last gear box.
As a further improvement of the above technical solution:
the lower end of the lower gear box is connected with a rudder blade-shaped lower strut.
The lower gear box is integrally cast with the rudder blade-shaped upper support, and the rudder blade-shaped lower support is detachably connected to the bottom of the lower gear box through a bolt.
And the upper side of the rudder blade-shaped upper support is connected with a connecting flange plate used for connecting a slewing mechanism.
And both sides of the lower gear box are rotatably connected with propellers.
The utility model has the advantages as follows: hydrodynamic layout rudder propeller that turns round all around, rotation mechanism include gear box down, and the last pillar and the lower pillar of rudder blade shape are connected to gear box down, and hydrodynamic layout rudder propeller that turns round all around has conventional rudder blade and the advantage of rudder propeller that turns round all around concurrently, can satisfy the application of torrent section and medium and high-speed ship, have better maneuverability, and it is more energy-conserving to steer the in-process, and the last pillar and the lower pillar of rudder blade appearance are streamlined in addition, and the water flow resistance is little, and energy-conserving effect of totality is obvious.
Drawings
Fig. 1 is the utility model provides a hydrodynamic layout rudder propeller's elevation view.
Fig. 2 is a schematic structural diagram of a hydrodynamic layout full-rotation rudder propeller slewing mechanism provided by the present invention.
In the figure: 1. installing a plate frame; 2. an upper gearbox; 3. a lubricating oil tank; 4. a rudder blade-shaped upper strut; 41. a flange plate; 5. a lower gear box; 6. a propeller; 7. a rudder blade-shaped lower strut.
Detailed Description
The following describes a specific embodiment of the present embodiment with reference to the drawings.
As shown in fig. 1 and fig. 2, the hydrodynamic layout full-rotation rudder propeller of this embodiment, including installation grillage 1, connect upper gear box 2 and lubricating oil tank 3 on the installation grillage 1, installation grillage 1 lower extreme rotates and connects rotation mechanism, rotation mechanism includes rudder blade shape upper prop 4 and lower gear box 5, lower gear box 5 forms with the whole casting of rudder blade shape upper prop 4, lower gear box 5 downside passes through bolt detachable and connects rudder blade shape lower prop 7, rudder blade shape upper prop 4 upside connection flange 41, rotation mechanism passes through flange 41 and is connected with the slewing mechanism in the installation grillage 1, lower gear box 5 both sides all rotate and connect screw 6, two screws 6 pass rotation mechanism and installation grillage 1 through drive mechanism and are connected with upper gear box 2.
When the hydrodynamic layout rudder propeller of this embodiment uses, the hydrodynamic layout rudder propeller passes through installation grillage 1 and connects the boats and ships hull, rudder blade shape goes up pillar 4, under gear box 5 and the rudder blade shape pillar 7 swivelling joint at installation grillage 1 downside, it passes rudder blade shape to go up pillar 4 and 5 oar power transmission to screw 6 of lower gear box through drive mechanism to go up gear box 2, can provide boats and ships thrust, and because pillar 4 and rudder blade shape pillar 7 exist down on the rudder blade shape, make the rudder propeller of gyration have the advantage of traditional rudder blade, can satisfy torrent navigation section and medium and high-speed ship and use, make the rudder propeller operability of gyration better, pillar 4 and rudder blade shape pillar 7 are streamlined down in addition, the water flow resistance is little, energy-conserving effect is obvious.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
