The specific embodiment
Now with embodiments of the present invention will be described by referring to the drawings in detail.
Fig. 1 is the mounting structure figure of a kind of liftable all-direction propeller of the present invention.This scalable all-direction propeller generally integrally is installed on the propelling unit cabin in the hull.As shown in Figure 1, this all-direction propeller mainly comprises: main motor 101, motor bearing 102, hydraulic ram 103, spline shaft 104, propelling unit cabin 105, hull are strengthened structure 106, guiding mechanism 107 and cylindrical shell 108 under water.
According to groundwork of the present invention, liftable all-direction propeller of the present invention needs to comprise at least: main motor 101, motor bearing 102, hydraulic ram 103 and cylindrical shell 108.
Wherein, main motor 101 is arranged on the motor bearing 102.Hydraulic ram 103 as lift system is fixed on the motor bearing 102 by a bearing pin.The upper box body of cylindrical shell 108 is connected with a connector at the place, bottom of hydraulic ram 103, realizes propelling unit rise and fall function.Guiding mechanism 107 has pilot bar under water, this under water the pilot bar of guiding mechanism 107 be connected with cylindrical shell 108 via a plate, guarantee that cylindrical shell can vertically move in the process that rises or descend.Preferably, this pilot bar is two, but the present invention is not limited to this, can adopt the pilot bar of any amount according to actual needs.
