Abstract
A motor boat propeller with filtering bossing comprises a propeller mounted at the rear lower end of the hull, and a filtering bossing mounted around and in the front of the propeller. The filtering bossing comprises a guide shell and a cone connected to the front end of the guide shell, an opening is provided at the top of the cone, through holes in the front of the guide shell and on the cone, and a fixing mechanism provided in the upper part of the guide shell for connection to the hull. The utility model is characterized in that since the guide shell guides water backward, the utilization ratio of the power is increased greatly, energy conserved and operating costs reduced; the through holes in the front of the guide shell holds back and filters impurities and aquatic plants, protects the propeller from being twisted and assures proper operation.
Description
Technical field
The utility model relates to the screw propeller on a kind of power driven vessel, specifically is a kind of power driven vessel screw propeller that has the water conservancy diversion filter mantle.
Background technology
Screw propeller on existing a kind of power driven vessel is installed in the lower end of afterbody, and axle drive shaft passes backward from the protrusion position of hull lower end, at the front end of this axle drive shaft paddle wheel is housed.Driving engine when operation in the ship drives the screw propeller rotation by transmission device and promotes current backward, thereby the power that produces forward advances hull.The shortcoming of this screw propeller is that the direction that paddle wheel rotation drives current not only comprises backward, also have towards around various directions, the loss that this just causes a part of power has reduced the degree of utilization of power, has wasted the energy, has increased operating cost; When hull navigates by water in addition, can twine foreign material or hydrophyte on the screw propeller in water, influence its normal operation, when serious even can quit work, and remove very difficulty of these foreign material.
Summary of the invention
The purpose of this utility model just provides a kind of power driven vessel screw propeller that has the water conservancy diversion filter mantle, that prior art exists wastes energy the increase operating cost because water (flow) direction disperses to reduce the degree of utilization of power to solve; And owing to screw propeller twines the problem that foreign material or hydrophyte influence its normal operation.
The technical solution of the utility model is: comprise the screw propeller that is loaded on the afterbody lower end, described screw propeller around and the front portion one water conservancy diversion filter mantle is housed, this water conservancy diversion filter mantle constitutes by stream guiding barrel and with its front end bonded assembly cone, top at this cone is provided with opening, on the front portion of this stream guiding barrel and cone, be covered with through hole, be provided with on the top of described stream guiding barrel and be used for and hull bonded assembly fixed mechanism.
Necking end at this cone is provided with interface.
Described interface is flange or a plurality of fixedly ear with holes that has fixed orifice.
Described fixed mechanism is and the curved ear of both sides, described stream guiding barrel top bonded assembly, is provided with fixed orifice on this curved ear.Described stream guiding barrel is a conical shell, and its rear end is a miner diameter end.
The utility model has the advantages that: because the guide functions of stream guiding barrel has improved the degree of utilization of power greatly with the current deflecting rear, saved the energy, reduced operating cost; Foreign material and hydrophyte have been filtered in the through hole prevention of stream guiding barrel front portion, have avoided screw propeller to be wound, and have guaranteed its normal operation.

Fig. 1 is an overall structure scheme drawing of the present utility model;
Fig. 2 is the sectional structure scheme drawing of the stream guiding barrel of utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Referring to Fig. 1～Fig. 3, the utility model comprises the screw propeller 2 that is loaded on lower end, hull 1 rear portion, described screw propeller 2 around and the front portion one water conservancy diversion filter mantle 3 is housed, this water conservancy diversion filter mantle 3 constitutes by stream guiding barrel 31 and with its front end bonded assembly cone 34, top at this cone is provided with opening, is provided with the flange 35 of band fixed orifice 36 at this open end.Also available 3～4 of flange 35 replaces (not shown) along the uniform fixedly ear with holes of open circumferential.On front portion of this stream guiding barrel 31 (being the right of screw propeller 2 positions) and cone 34, be covered with through hole 33.Be provided with on the top of described stream guiding barrel 31 and be used for and hull 1 bonded assembly fixed mechanism 32.The embodiment of fixed mechanism 32 is and described stream guiding barrel 31 top both sides four curved ears of bonded assembly (referring to Fig. 3), is provided with fixed orifice on this curved ear.
Described stream guiding barrel 31 is a conical shell, and its rear end is a miner diameter end.Such structure has the function of the current that flow through being concentrated pressurization, and current spray stronger in back outlet, produce bigger counteraction propelling thrust.
Water conservancy diversion filter mantle 3 of the present utility model is connected with the front that hull bottom salient stretches out the axle drive shaft of screw propeller 2 its front end interface flange 35 when using with screw; The fixed mechanism 32 usefulness screws of its cylindrical shell 31 are connected with the bottom of hull 1.
Claims (5)
1, a kind of power driven vessel screw propeller that has the water conservancy diversion filter mantle, comprise the screw propeller that is loaded on the afterbody lower end, it is characterized in that: described screw propeller around and the front portion one water conservancy diversion filter mantle is housed, this water conservancy diversion filter mantle constitutes by stream guiding barrel and with its front end bonded assembly cone, top at this cone is provided with opening, on the front portion of this stream guiding barrel and cone, be covered with through hole, be provided with on the top of described stream guiding barrel and be used for and hull bonded assembly fixed mechanism.
2, the power driven vessel screw propeller that has the water conservancy diversion filter mantle according to claim 1, it is characterized in that: the necking end at this cone is provided with interface.
