Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, this hair of Detailed description of the invention is now compareed
Bright specific embodiment.
Fig. 1 is the perspective view for showing gondola driver accoding to exemplary embodiment, and Fig. 2 is shown according to exemplary implementation
The cross-sectional view of the gondola driver of example.As shown in Figures 1 and 2, gondola driver accoding to exemplary embodiment may include
Shell 100, motor 300, propeller 500 and water flow guiding elements 700.Gondola driver accoding to exemplary embodiment can be with
It is mounted on the bottom of the hull of ship and can be located under the water surface, for example, can be immersed in seawater.
Shell 100 can have the installation space for installing motor 300.For example, shell 100 may include middle part
110 and the side positioned at middle part first end 130 and the second end 150, and can be common by middle part 110 and end 130,150
Limit installation space.Shell 100 can be formed by the material of such as steel.In one exemplary embodiment, shell 100 can lead to
It crosses increasing material manufacturing (AM) technique to be formed, this will be described in detail hereinafter.
