Abstract
The invention discloses an eddy propeller comprising a shell. The shell is provided with a water outlet and a water inlet, and a bearing seat is mounted at the top of the shell. An outboard engine is connected to the upper end of the bearing seat, and a driving shaft of the outboard engine is vertically arranged in the shell and connected with an impeller. A gap is reserved between the impeller and the shell. The outboard engine drives the impeller on the driving shaft to rotate, the small gap exists between the impeller and the shell, water flow can flow in from the water inlet and is ejected out from the water outlet along the shell without flowing back when the impeller rotates at a high speed, and the impeller rotates to drive the water flow to be ejected from the water outlet so as to generate propulsive force for propelling a ship forward or backward; by the design, the ship can be ensured to sail in shoals normally, and the problem that a conventional outboard engine impacts on underwater reefs and stumps as a result of accidents is avoided.
Description
Technical field
The present invention relates to a kind of eddy current propelling unit, belong to outboard engine propelling unit technical field.
Background technology
The appearance of outboard engine provides a great convenience for mankind's waterborne traffic, people can steer a ship easily and arrive the destination of oneself, and need not consider oneself whether to have enough muscle power and skill to control this traditional driving tool of strut, oar and big shield, but, outboard engine has a unavoidable shortcoming, in order to guarantee propulsion coefficient, the propulsive units of outboard engine is all lower than hull bottom, this means, the waters outboard engine excessively shallow in the depth of water cannot provide power, such as there being the marsh in countless shoals; And while navigating by water in shoal, once knock the object of reef stub under the water surface and so on, the heavy personal casualty that causes gently runs out of steam.
Summary of the invention
Technical matters for above-mentioned existence, the object of the invention is: proposed a kind ofly can normally to travel in shoal, the eddy current propelling unit of safety.
Technical solution of the present invention is achieved in that a kind of eddy current propelling unit, comprises housing, and housing is provided with water outlet and water inlet, and described case top is provided with bearing seat; Described bearing seat upper end is connected with outboard engine driving engine; The axle drive shaft of described outboard engine driving engine is vertically set in housing, and axle drive shaft is connected with impeller; Between described impeller and housing, leave gap.
Preferably, described water outlet is tapered.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of eddy current propelling unit of the present invention, by the wheel rotation on outboard engine driven by engine axle drive shaft, between impeller and housing, there is little gap, when impeller high speed rotating, water flow energy enters and penetrates at a high speed and can not flow backwards from water outlet along housing from water inlet, wheel rotation promotes current and advances or fall back from the spouting generation propulsive force promotion of water outlet ship, such design can guarantee that ship normally travels in shoal, has also avoided traditional outboard engine to run into the problem that underwater reefs stub has an accident.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the angle of rake structural representation of a kind of eddy current of the present invention;
Wherein: 1, housing; 2, water outlet; 3, water inlet; 4, bearing seat; 5, outboard engine driving engine; 6, axle drive shaft; 7, impeller.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
By outboard engine driving engine 5, drive the impeller 7 on axle drive shaft 6 to rotate, there is little gap in 1 of impeller 7 and housing, when impeller 7 high speed rotating, water flow energy enters and penetrates at a high speed and can not flow backwards from water outlet 2 along housing 1 from water inlet 3, impeller 7 rotates promotion current and advances or fall back from the spouting generation propulsive force promotion of water outlet 2 ship, such design can guarantee that ship normally travels in shoal, has also avoided traditional outboard engine to run into the problem that underwater reefs stub has an accident.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
