≪ Operation of Example &

Hereinafter, the operation of the amphibious caravan having excellent stability of the ship according to the present invention constructed as described above will be described.

The amphibious camping caravan of the present invention is mounted on a trailer on the ground or traction by a towing vehicle, and is used for camping on the land of a destination desired by the user. When the amphibious camping caravan of the present invention is to be used in a watercraft, the watercraft is moved to the watercraft and floats on the watercraft. At this time, buoyancy can be added to the hull 10 by horizontally spreading the floating wings 12 on both sides of the hull 10.

After the camping caravan is lifted in this manner, the rollover prevention tube 17 constructed in the present invention is operated to prevent the camping caravan from overturning in the water.

3 and 6, the pair of hatch doors 15 are engaged with each other to block the lower end of the tube loading part 14 in a horizontal state, and the tube loading part 14 The rollover prevention tube 17 is installed in the inside of the housing. At this time, water (seawater) may be completely or partially contained in the rollover prevention tube 17.

Thereafter, when the drive motor 16c of the door operating means 16 is driven forward, the spline shaft 16b connected to the drive shaft of the drive motor 16c is connected to the boss 16a coupled to the spline shaft 16b, And the hatch door 15 integrally coupled to the boss 16a rotates toward the water to open the lower end of the tube loading portion 14 in a V-shape as shown in Fig. At this time, the pair of hatch doors 15 are rotated so as to form a V-shape, and the rotation stop is stopped while the vicinity of the center of rotation is stopped by the latching jaws 14b and is supported by the latching jaws 14b.

Subsequently, water is supplied to the inside of the rollover prevention tube 17 by driving the water supply and drain pump 18. As the water is swollen inside the rollover prevention tube 17, the rollover prevention tube 17 expands into water in a V-shaped cross-sectional shape as shown in FIG. Thus, the rollover prevention tube 17 lowers the center of gravity of the hull 10 downward, thereby preventing the overturning of the camping caravan of the present invention when the watercraft is operated in the watercraft.

The bottom surface of the rolled rollover prevention tube 17 is formed so that the bottom surface of the rollover prevention tube 17 is formed in a V shape in a state in which the engagement portion 15a of the hatch door 15 is engaged with the pair of hatch doors 15. [ .

On the other hand, when the camping caravan is moved back to the ground, the water supply and drainage pump 18 is drained to discharge the water (seawater) in the rollover prevention tube 17 to the outside. When the drive motor 16c of the door operating means 16 is driven to rotate in the opposite direction, the spline shaft 16b is reversely rotated and the boss 16a coupled to the spline shaft 16b rotates reversely, The hatch door 15 integrally coupled to the hatch door 15 rotates in a direction in which the lower end of the tube loading part 14 is shielded (that is, the direction in which the hatch door is closed), thereby closing the lower end of the tube loading part 14.

When the hatch door 15 is closed, the rollover prevention tube 17 is pushed into the tube loading part 14 by the hatch door 15 and contracted. Since the bottom surface of the rollover prevention tube 17 has a swallow tail-like sectional structure, the rollover prevention tube 17 smoothly contracts with respect to the center of the bottom surface of the rollover prevention tube 17, .

As described above, in the amphibious caravan of the present invention, since the rollover prevention tube 17 is inflated in the water so that the center of gravity of the hull 10 is lowered, the load is concentrated to the right or left, It is possible to safely operate the watercraft without overturning to a stable float state.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, This is possible.
