Abstract
The utility model provides a double-duct propeller ship thruster. A duct is respectively installed on two sides including a left side and a right side of the back portion of a ship body, duct axes of two ducts intersect to form an angle of 45 degrees, a propeller is respectively installed in each duct, one of two propellers rotates towards the left, and the other propeller rotates towards the right. Compared with a ship with the same driving force, the double-duct propeller ship thruster has large propulsive force.
Description
Technical field
The utility model relates to a kind of marine propeller, specifically two shrouded propeller marine propellers.
Background technology
Existing boats and ships are all that a screw propeller promotes after current direction, rely on water body to the boats and ships antagonistic force, and boats and ships are pushed forward.Because backward current relatively disperse, water body is also just smaller to the antagonistic force of boats and ships.The speed that boats and ships advance is slow.
Summary of the invention
The purpose of this utility model is a kind of Novel propeller of design, increases water body to the boats and ships antagonistic force.
The utility model is to realize like this design goal:
In the left and right sides of afterbody, each installs a duct 2, makes the duct axis 5 of two ducts 2 intersect 45 degree; In every duct 2, each installs a screw propeller 3, makes in two screw propellers 3, and one is left-handed, and another is dextrorotation.The left and right is one group, i.e. two shrouded propeller propelling units.Can add as needs and dress up three groups or more.
Because backward current are by duct 2, concentrate from duct outlet 4 and discharge, so current backward are very concentrated, water body is also just larger to the antagonistic force of boats and ships; Again because the duct axis 5 of two ducts 2 intersects 45 degree, and in two screw propellers 3, one is left-handed, another is dextrorotation, so two current backward impact mutually in intersection, more strengthen water body to the boats and ships antagonistic force, promote boats and ships and advance fast.
Description of drawings
Fig. 1 is the utility model structural representation.
Sequence number in upper figure: duct entrance 1, duct 2, screw propeller 3, duct outlet 4, duct axis 5.
The specific embodiment
Below in conjunction with accompanying drawing, a non-limiting examples is illustrated.
In the left and right sides of afterbody, each installs a duct 2, makes the duct axis 5 of two ducts 2 intersect 45 degree; In every duct 2, each installs a screw propeller 3, makes in two screw propellers 3, and one is left-handed, and another is dextrorotation.
The utility model both can use in new boats and ships, can reequip existing ship again.Compare with the boats and ships of identical power, have larger propulsive force.
The utility model can also be as the propelling unit of the aircraft such as aircraft.
Claims (2)
1. two shrouded propeller marine propellers, it is characterized in that: in the left and right sides of afterbody, each installs a duct (2); In every duct (2), each installs a screw propeller (3).
2. according to claim 1 pair of shrouded propeller marine propeller is characterized in that: the duct axis (5) of two ducts (2) intersects 45 degree; In two screw propellers (3), one is left-handed, and another is dextrorotation.
