Abstract
The utility model discloses with kind of a catheter type propeller, including propeller hub, it is connected with propeller hub and is connected to blade, blade is uniformly distributed on the periphery of propeller hub, there is terrace with edge on the blade tip edge of blade, terrace with edge is located at the pressure face side of blade, and terrace with edge is vertical with pressure face, and the thickness A of the terrace with edge and the height B of terrace with edge are the 1.5% of airscrew diameter.The catheter type propeller of the utility model, due to having a terrace with edge perpendicular to blade pressure face in the blade tip edge of blade, when rotation, can generate larger thrust, hence it is evident that improve efficiency, reduce operating cost.
Description
Technical field
The utility model is related to a kind of catheter type propellers.
Background technology
Catheter type propeller is a kind of driving tool of ship, refers to that diversion pipe, propeller position are added around propeller
In in diversion pipe, that is, its periphery is covered with a kind of propeller of diversion pipe after propeller installation, and the vertical section of diversion pipe is
Airfoil type, diversion pipe is installed below ship stern forms a unified ichthyoid with hull.Conventional manifold formula propeller due to
The rectified action of diversion pipe increases propeller taper load, so that thrust increases, especially suitable for big in low speed, needs
It is used on the ship of thrust, such as tugboat, push wheel and cargo ship.This propeller arrangement be include propeller hub, be connected with propeller hub and be connected to paddle
Leaf, blade are uniformly distributed on the periphery of propeller hub.Although existing catheter type propeller can generate larger thrust, propeller
The torque being subject to also increases, and needs larger power that can just make its rotary work, therefore conventional manifold formula propeller propulsive efficiency is past
Toward not high, operating cost height.
Invention content
The purpose of this utility model is to provide a kind of thrust and torque increasing propeller itself, improves propulsive efficiency,
Reduce the catheter type propeller of operating cost, overcome the deficiencies in the prior art.
The catheter type propeller of the utility model, including propeller hub, are connected with propeller hub and are connected to blade, and blade is on the periphery of propeller hub
It being uniformly distributed, there is terrace with edge, terrace with edge to be located at the pressure face side of blade on the blade tip edge of blade, terrace with edge is vertical with pressure face,
The thickness A of the terrace with edge and the height B of terrace with edge are the 1.5% of airscrew diameter.
The catheter type propeller of the utility model, due to having the rib perpendicular to blade pressure face in the blade tip edge of blade
Platform, propeller itself can generate larger thrust when rotation, hence it is evident that improve efficiency, reduce operating cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is that vertical view shown in FIG. 1 reduces schematic diagram.
Specific implementation mode
As shown in Figure 1, 2：For the shape of clear expression blade, a blade 2 is only drawn in wherein Fig. 1, is actually existed
There are equally distributed four blades 2 on 1 periphery of propeller hub（Such as Fig. 2）.
The catheter type propeller of the utility model, including propeller hub 1 are connected with propeller hub 1 and are connected to blade 2, blade 2 and propeller hub 1
Between junction formed handing-over line 3.Blade 2 is uniformly distributed on the periphery of propeller hub 1, has terrace with edge 4 on the blade tip edge of blade 2,
Terrace with edge 4 is located at 6 side of pressure face of blade 2, and terrace with edge 4 is vertical with pressure face 6, the thickness A of the terrace with edge 4 and the height B of terrace with edge
It is the 1.5% of airscrew diameter.Due to there is the terrace with edge of the pressure face 6 perpendicular to blade in the blade tip edge of blade, when rotation
Propeller itself can generate larger thrust, hence it is evident that improve efficiency, reduce operating cost.
