Abstract
The utility model relates to structurally modification of ship propulsion devices and provides a ship propulsion device effective in protection and propelling. The ship propulsion device comprises a shell. The front end of the shell is provided with a water inlet. Both sides of the rear end of the shell are provided with water outlets. The ship propulsion device is structurally characterized in that a strainer is disposed at the water inlet, and a propeller device is disposed in the middle of the shell and is composed of five mutually-opposite four-blade propellers serially connected through a rotary shaft. A power input end of the rotary shaft is connected with a power output end of an engine. A power switch valve is disposed at each water outlet.
Description
Technical field
The utility model relates to the improvement of marine propeller structure.
Background technology
Marine propeller is the instrument that thrust is provided on the boats and ships, and its effect is the power conversion that marine powerplant provides to be become thrust, propelling ship.It is the energy converter that natural force, manpower or mechanical energy is converted to boats and ships thrust.Propelling unit can be divided into active and reaction equation two classes by the mode of action.Drive fibre that ship advances, sail etc. for active by manpower or wind-force, oar, big shield, paddle wheel, waterjet propulsor, screw propeller etc. are reaction equation.The modern transportation boats and ships adopt the reaction equation propelling unit mostly, and most widely used is screw propeller.
Angle of rake propelling effect and the protection effect of existing employing propeller type are not very desirable, require further improvement.
Summary of the invention
The utility model is exactly for the problems referred to above, and the marine propeller that a kind of protection effect is good, propelling is effective is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises housing, the housing front end is provided with water inlet, both sides, housing rear end are provided with water outlet, and its structural feature water inlet is provided with filtering net, and the housing middle part is provided with propeller arrangement, propeller arrangement is composed in series by a rotating shaft by five mutual four pages of reverse screw propellers, and the power intake of rotating shaft links to each other with the engine power mouth; Described water outlet goes out to be provided with the power switch valve.
As a kind of preferred version, housing described in the utility model is Stainless Steel Shell.
