FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a schematic top view of the present invention;
FIG. 3 is a schematic top view of the hull;
in the drawings are labeled: 1, a ship body; 2-a hydraulic device; 3-a hinged seat; 4-a propeller; 5-central shaft of propeller; 6-a rotating shaft; 7-concave structure.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
As shown in fig. 1, a marine side propeller connecting structure includes a hull 1 and a side propeller device, wherein the side propeller device includes a propeller 4, a propeller central shaft 5, a hydraulic device 2;
the improved ship is characterized in that an inwards concave structure 7 is arranged below the water level line on the 1 side of the ship body, a hydraulic device 2 is hinged to the upper portion of the inwards concave structure 7, a hinged seat 3 is arranged in the middle of the propeller center shaft 5, the tail portion of the hydraulic device 2 is connected with the hinged seat 3, the hydraulic device 2 can drag the propeller center shaft 5 to move in a hinged connection mode, a rotating shaft 6 is arranged at the bottom of the inwards concave structure 7 of the ship body, the tail portion of the propeller center shaft 5 is connected with the rotating shaft 6, the top portion of the propeller center shaft is connected with the propeller 4, and.
When the propulsion device on one side of the ship body 1 is completely unfolded, the hydraulic device 2 is also completely unfolded, the central shaft 5 of the propeller is horizontally placed, a gap exists between the central shaft and the bottom of the ship body concave structure 7 when the central shaft is horizontally placed, meanwhile, the propeller 4 completely extends out to be fully contacted with water, and the distance exists between the propeller 4 and the outermost edge of the ship body concave structure 7, so that the rotation of the propeller is not influenced, the resistance can be increased due to the close proximity of the propeller, and the energy loss is increased.
When the propulsion device on one side of the ship body 1 is completely retracted, the hydraulic device 2 is also completely retracted, the central shaft 5 of the propeller is vertically placed, a gap exists between the top of the propeller 4 and the top of the concave structure 7 of the ship body, and the outermost edge of the propeller 4 is completely arranged in the concave structure 7 of the ship body, so that when some side propulsion devices do not work, resistance cannot be increased for advancing of the ship, and sundries such as aquatic weeds and the like cannot be hooked.
