<Means for solving the problem> Therefore, in this invention, the propulsion system will not be damaged even if overload occurs due to algae etc. entangled in the foreign car, and the long screw is rotated underwater using an internal combustion engine like in general. In addition to the main propulsion system that uses the same internal combustion engine to propel the ship, it is also possible to propel the vessel by a sub-propulsion system that uses the same internal combustion engine to stir the water with a floating paddle wheel through an air motor. In addition, in the present invention, paddle wheels rotated by motors are installed on both the port and starboard sides, and fender frames are installed around these paddle wheels to prevent the ship from sinking rapidly. That is, the present invention includes a main propulsion device including a screw that rotates underwater via a shaft when an internal combustion engine is operated, an air motor that rotates by operating a compressor connected to the internal combustion engine, and a rotating shaft of the motor. A sub-propulsion device including a paddle wheel connected to a speed reducer to rotate at a reduced speed while stirring water, and a propulsion paddle wheel having the paddle wheel installed in a fender frame on both sides. do.

<Example> An embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in the figure, the present invention is equipped with an internal combustion engine 2 at the slightly rear center of a hull 1, and when the two internal combustion engines 2 operate, a shaft 3 extending rearward and a screw 4 protruding outside the hull at the tip are rotated. Equipped with a main propulsion device. On the other hand, in the present invention, a compressor 5 is connected to both sides of the internal combustion engine, and an accumulator 6 is connected to the rear of the hull 1 from the compressor 5.

The apparatus is equipped with an auxiliary propulsion device that rotates the paddle wheel 19 by rotating an air motor 20 through hoses 18a, 18b, 18c, and 18d connected to the distribution pipe 15.
A worm gear 34 serving as a speed reducer is connected to the rotating shaft of each air motor 20 to rotate the outer wheel 19 at a reduced speed. Specifically, a worm gear 34 is engaged with the rotating shaft of the air motor 20, and the outer wheel 19 is supported by a bearing of the hull 1 in a connecting hole 25 formed in the center of the rotating plate 24.
It passes through the shaft 26 of. The outer wheel 19 is supported by an inner drum 27 and an outer wheel drum 28 provided around a shaft 26, and protrudes a pair of aluminum leg plates 29 that have a rectangular cross section and become thinner toward the outside from the root. Insert the water stirring plate 30, which is thin at the bottom and concave at the bottom and thick at the center and gradually becomes thinner at the tip.
0 is exchangeably fixed by bolts and nuts 31.

On the other hand, in the present invention, in addition to the automatic operation using the air motor, a manual handle 32 is provided near the bow, and the manual handle 32 has a handle rod 33 attached along the gunwale, and a part of the handle rod 33 is attached to the worm gear 34 of the foreign car 19. By meshing, the handle 32 is moved to allow the paddle wheel 19 to move the boat forward or backward.

In the present invention, the accumulator 6 is connected to an air pipe 10 via a manual valve 9 at the inlet of a pipe joint 8, and is connected to the air pipe 10 by an air motor 11 with a reduction gear in the water at the tip of a shaft 12 that protrudes outside the boat. By connecting to the rotating screw 13, an auxiliary propulsion device can also be provided.

Further, in the present invention, the outer car 19 is provided with a fender frame that also serves as an air chamber by the upper deck 39 and the side fender walls 38, so that it can be prevented from sinking even if water floods into the ship.

The distribution pipe 15, pipe 14, and hose 18
A main valve 21 is provided at the connecting portion of a, 18b, 18c, and 18d.A control rod 22 is installed near the main valve 21, and by stretching a wire 23 connecting the control rod 21, the air motor 20 is rotated forward in one direction, reversed, or stopped rotating.

Furthermore, unless the paddle wheel 19 is operated with the rotating shaft 26 above the water, the water stirring plate 30 cannot sufficiently stir the water. The rotary shaft 26 to which the water stirring plate 30 is attached is designed to be above the water. The rear end of the handle rod 33 is a worm gear 40.
It is connected to the central connecting rod 38 through. Therefore, when either handle 32 is moved, both handle rods 33 move and the outer wheel 19 can be rotated. Also, the steering handle 3 near the bow
5, a rod 36 extends toward the stern and operatively connects a rudder 37 to the rear of the screw 13.

<Function> This ship has the outer car 19 arranged as described above, the internal combustion engine 2, the compressor 5, and the accumulator 6.
In order to operate the ship, first, the internal combustion engine 2 is activated to rotate the shaft 3 and screw 4 to directly provide the propulsive force of the main propulsion device, and at the same time, the compressed air produced by the compressor 5 is is once stored in the accumulator 6, and a part of it passes through the air pipe 10 to the air motor 11 with a reducer.
to rotate the shaft 12 and screw 1 at the same time.
3 is rotated to provide the propulsive force of the auxiliary propulsion device together with the screw 4. On the other hand, other compressed air from the accumulator 6 is sent to a distribution pipe 15 at the bow of the ship through an air hose 14. There are intermediate valves 16 on both sides of the pressure gauge of the flow pipe 15, and the flow of the compressed air can be adjusted depending on the pressure. Also, pipe 1 of distribution pipe 15

A main valve 21 is provided at the entrance to the ports c and 18d so that each outer car 19 can be moved independently.

Hoses 18a, 18b, 1 from the distribution pipe 15
Compressed air is sent to the air motor 20 through 8c and 18d. A wire 23 from the operating rod 22 can operate the operating rod 22 to switch the air motor 20 to rotate forward or reverse, thereby causing the outer vehicle 19 to move forward or backward. Thus, the rotation of the shaft 26 of the outer wheel 19 provides a propulsive force to the water stirring plate 30. This water stirrer plate 30 is fixed to a leg plate 29 protruding from the inner drum 27 of the outer car 19 with bolts and nuts 31, and if the water stirrer plate 30 has been used for a long period of time, it may be replaced by loosening the bolts and nuts 31. I can do it.

On the other hand, this boat has a handle 32 that moves a handle rod 33, and the rotation of the handle rod 33 is caused by a worm gear 34 to rotate the outer wheel 19.
The ship can also be propelled manually. Therefore, the internal combustion engine 2 of this ship broke down, and the air motor 1
Even if 1 or 20 is out of order, manual navigation is possible. Further, the steering is performed by moving a steering rod 36 and a rudder 37 using a steering handle 35 to change the direction.

<Effects of the invention> This invention, which has the above-mentioned configuration, navigates a ship using the main propulsion device using a screw from an internal combustion engine and the auxiliary propulsion device using a paddle wheel. It is less noisy and requires less exhaust gas such as smoke, which not only saves energy, but also allows for cleaner navigation in bays, rivers, and for sightseeing in glue marshes. especially,
In the present invention, navigation is possible not only by the main propulsion device but also by the auxiliary propulsion device equipped with a speed reducer, and safe navigation is possible without causing an accident with one of the vessels and causing the vessel to drift due to the other. Furthermore, although the outer wheel is rotated by an air motor, the water stirring plate of the outer wheel does not cause damage such as burning out of the device even if overload occurs due to water resistance or floating obstacles. Furthermore, in this design, the outer cars are installed inside the fender frames on both sides, so even if the ship were to flood, the fender frames would act as air chambers to prevent the vessel from sinking.
