Abstract
The utility model discloses a kind of stern dynamic structurals of ship, including hull, the hull tail end is equipped at least one flow-guiding mouth, the section of the flow-guiding mouth is in " S " type, dynamic structural is set on the flow-guiding mouth, the dynamic structural includes diversion pipe, radome fairing, rudder and propeller, and the propeller, radome fairing and rudder are set in turn in diversion pipe along axial direction, and the diversion pipe is straight barrel type structure；The propeller center is equipped with transmission shaft, and transmission shaft is in horizontally disposed, and transmission shaft is higher than hull bottom surface.The stern dynamic structural of the ship of the utility model, bigger to the thrust of hull, horizontally disposed transmission shaft has shortened length, has reduced costs, and the space utilization rate of cabin is improved, moreover it is possible to reduce the probability that hits a submerged reef.
Description
Technical field
The utility model relates to a kind of stern dynamic structurals of ship.
Background technique
In existing ship, as shown in Figure 1, propeller 101 is in the lower section of ship, transmission shaft 102 is obliquely installed, and
Transmission shaft 102 extends to the lower section of hull, this needs to configure longer transmission shaft 102, leads to increased costs, in addition, transmission shaft
102 Position Design causes engine 103 more placed in the middle in the position of cabin, so that the space utilization rate of cabin is lower；Moreover,
The propeller 101 for more leaning on bottom, increases the resistance of ship in motion, also increases the risk hit a submerged reef.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of stern dynamic structural of ship, it can be with.
In order to solve the above technical problems, the technical solution of the stern dynamic structural of the utility model ship are as follows:
Including hull, the hull tail end is equipped at least one flow-guiding mouth, and the section of the flow-guiding mouth is in " S " type, described
Dynamic structural is set on flow-guiding mouth, and the dynamic structural includes diversion pipe, radome fairing, rudder and propeller, the propeller, rectification
Cover and rudder are set in turn in diversion pipe along axial direction, and the diversion pipe is straight barrel type structure；The propeller center is equipped with transmission
Axis, transmission shaft is in horizontally disposed, and transmission shaft is higher than hull bottom surface.
The 1/2 of the dynamic structural or 1/3 is partially in the lower section of hull bottom surface.
The center of the radome fairing is equipped with the flow guiding head of bullet shape.
What the utility model can achieve has the technical effect that
Compared with prior art, the stern dynamic structural of the ship of the utility model, using the diversion pipe of straight barrel type structure,
The loss of propeller circumferential direction induced power can be reduced；
Compared with prior art, the stern dynamic structural of the ship of the utility model, 1/2 or 1/3 part of dynamic structural
Lower section in hull bottom surface, in conjunction with the flow-guiding mouth of " S " type, so that water flow is more smooth.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments:
Fig. 1 is the structural schematic diagram of the utility model background technique；
Fig. 2 is the structural schematic diagram of the stern dynamic structural of the utility model ship；
Fig. 3 is the portion the A enlarged drawing of Fig. 2；
Fig. 4 is the structural schematic diagram of the embodiment one of the stern dynamic structural of the utility model ship；
Fig. 5 is the structural schematic diagram of the embodiment two of the stern dynamic structural of the utility model ship.
Specific embodiment
As shown in Figure 2 and Figure 3, the utility model provides a kind of stern dynamic structural of ship, including hull 1, the ship
1 tail end of body is equipped at least one flow-guiding mouth 2, and the section of the flow-guiding mouth 2 is in " S " type, and power structure is arranged on the flow-guiding mouth 2
It makes, the dynamic structural includes diversion pipe 3, radome fairing 4, rudder 5 and propeller 6, and the propeller 6, radome fairing 4 and rudder 5 are along axis
To being set in turn in diversion pipe 3, the diversion pipe 3 is straight barrel type structure；6 center of propeller is equipped with transmission shaft 7, transmission
Axis 7 is in horizontally disposed, and transmission shaft 7 is higher than 1 bottom surface of hull.
The 1/2 of the dynamic structural or 1/3 is partially in the lower section of 1 bottom surface of hull.
The center of the radome fairing 4 is equipped with the flow guiding head 8 of bullet shape.
The stern dynamic structural of the ship of the utility model, as shown in figure 4, for the ship of one dynamic structural of setting, such as
Shown in Fig. 5, for the ship that two dynamic structurals are arranged.
Equipped with the ship of the stern dynamic structural of the utility model, in motion, water flow flows to " S " type along hull bottom
Flow-guiding mouth, subsequently into dynamic structural, the 1/2 of dynamic structural or 1/3 is partially in the lower section of 1 bottom surface of hull, so that ship
The water of 1 bottom of body preferably enters flow-guiding mouth 2 along hull bottom, to generate biggish thrust.
A kind of stern dynamic structural of ship provided by the utility model embodiment is described in detail above, this
It applies specific case in text to be expounded the principles of the present invention and embodiment, the explanation of above embodiments is
It is used to help understand the revealed technical solution of the utility model；At the same time, for those skilled in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification is not
It is interpreted as the limitation of the utility model.
