Nautical transport vehicle having enhanced stability

A nautical transport vehicle includes at least one floating member, at least one longitudinal fin pivotally mounted on the floating member, and at least one corresponding plate mounted on the floating member and parallel with the longitudinal fin. Thus, the nautical transport vehicle is immersed in the water stably to form a balance support, so that the ship mounted on the nautical transport vehicle is flush rested on the water surface smoothly to obtain tension and buoyancy efficiently.

The present invention relates to a nautical transport vehicle having highly enhanced multi-directional stability.

A conventional nautical transport vehicle in accordance with the prior art shown inFIG. 1is a row-shaped raft1consisting of a plurality of juxtaposed barrels11connected together. Thus, the conventional raft1has a larger contact area with the water surface, so that the conventional raft1has a greater stability. However, the conventional raft1has a slower velocity.

Another conventional nautical transport vehicle in accordance with the prior art shown inFIGS. 2 and 3is a boat2having a V-shaped bottom. However, the conventional raft boat2has a greater stability, so that the conventional raft boat2is easily turned over.

In accordance with the present invention, there is provided a nautical transport vehicle, comprising:

at least one floating member;

at least one longitudinal fin pivotally mounted on the floating member; and

at least one corresponding plate mounted on the floating member and parallel with the longitudinal fin, thereby defining a gap between the corresponding plate and the longitudinal fin to allow a water flow passing through the gap so as to reduce a resistance to a forward movement of the water flow and to adjust a turning angle of the floating member.

Referring to the drawings and initially toFIGS. 4 and 5, a nautical transport vehicle3in accordance with the preferred embodiment of the present invention comprises at least one floating member31, at least one longitudinal fin32pivotally mounted on the floating member31, and at least one corresponding plate33mounted on the floating member31and parallel with the longitudinal fin32, thereby defining a gap331between the corresponding plate33and the longitudinal fin32to allow a water flow passing through the gap331so as to reduce a resistance to a forward movement of the water flow and to adjust a turning angle of the floating member31.

As shown inFIG. 4, the nautical transport vehicle3comprises two layers of laminating longitudinal fins32, and a floating member31mounted between the two layers of laminating longitudinal fins32.

As shown inFIG. 5, the nautical transport vehicle3comprises two symmetrically arranged floating members31each having a hollow inside and each having a planar bottom to have a greater buoyancy.

Thus, the nautical transport vehicle3is immersed in the water stably to form a balance support, so that the ship mounted on the nautical transport vehicle3is flush rested on the water surface smoothly to obtain tension and buoyancy efficiently.

As shown inFIGS. 6-8, the nautical transport vehicle3comprises multiple layers of laminating longitudinal fins32, and multiple floating members31mounted between the multiple layers of laminating longitudinal fins32.

Thus, the nautical transport vehicle3has an adjustable height so that the nautical transport vehicle3is available for a deeper marine zone.

In addition, the nautical transport vehicle3further comprises a connecting plate34mounted on the corresponding plate33and juxtaposed to a bottom of a ship340for attaching the nautical transport vehicle3to the bottom of the ship340.

Thus, the nautical transport vehicle3is attached to a common ship340and is immersed in the water so as to function as a draft balance mechanism in the water. Alternatively, the upper floating members31are located above the water so as to function as an engine room or a deck.

In addition, the nautical transport vehicle3further comprises a plurality of pivot members311mounted on the floating members31to pivot with the water flow upward and downward so as to reduce the resistance to the forward movement of the water flow.

Thus, when the nautical transport vehicle3is located at a lower level, the water flow lifts the pivot members311to provide a buoyant effect to the nautical transport vehicle3and when the nautical transport vehicle3is located at a higher level, the water flow depresses the pivot members311to provide a diving effect to the nautical transport vehicle3. In addition, the pivot members311are pivoted with the water flow upward and downward so as to reduce the resistance to the forward movement of the water flow.

As shown inFIG. 9, the nautical transport vehicle3further comprises a plurality of control gates321each pivotally mounted between any two adjacent longitudinal fins32and each mounted between each of the longitudinal fins32and the corresponding plate33to provide a resistance to the forward movement of the water flow so as to reduce the velocity of the nautical transport vehicle3.

Thus, the control gates321are pivoted to form an obstruction to passage of the water flow to provide a braking effect so as to reduce the velocity of the nautical transport vehicle3, thereby decreasing consumption of the power.

As shown inFIGS. 10-13, the nautical transport vehicle3further comprises a plurality of foils312retractably mounted on the floating members31to expand outward to increase the area of the nautical transport vehicle3.

Thus, the foils312are expanded outward to increase the area of the nautical transport vehicle3to enhance stability and balance of the nautical transport vehicle3and to adjust the draft effect of the nautical transport vehicle3.

As shown inFIGS. 14-16, the nautical transport vehicle3further comprises an attachment float313detachably mounted on a bottom of the floating members31. Preferably, the attachment float313has a substantially arc-shaped profile and has a height gradually reduced from a forward end to a rearward end thereof.

Thus, the attachment float313is detached from the floating members31to prevent the nautical transport vehicle3from getting aground.

As shown inFIGS. 17 and 18, the nautical transport vehicle3comprises a plurality of longitudinal fins32pivotally mounted on the floating member31.

Thus, the longitudinal fins32are pivoted with the water flow to allow the water flow passing through the longitudinal fins32so as to reduce the resistance to the forward movement of the water flow. In addition, the longitudinal fins32are pivoted to adjust directions with the water flow so as to adjust the turning angle of the nautical transport vehicle3.

Accordingly, the nautical transport vehicle is assembled and disassembled easily and conveniently, thereby greatly facilitating assembly and disassembly of the nautical transport vehicle. In addition, the nautical transport vehicle3is immersed in the water stably to form a balance support, so that the ship mounted on the nautical transport vehicle3is flush rested on the water surface smoothly to obtain tension and buoyancy efficiently. Further, the longitudinal fins32are pivoted with the water flow to allow the water flow passing through the longitudinal fins32so as to reduce the resistance to the forward movement of the water flow.
