Abstract

An inland river passenger transport and vehicle roll-on-roll-off ship comprise a ship body and a multi-layer deck, a bulbous bow is arranged on the head portion of an underwater molded line of the ship body, and double-tail fins are arranged on the tail portion of the underwater molded line of the ship body. A full through type is adopted in a main deck of the multi-layer deck, a box shaped structure without a pillar is adopted on the transitional side wall, and a spring board is arranged at one end of the main deck. The full through type is adopted in the main deck and a passenger cabin deck is arranged on an upper deck so as to achieve a roll-on-roll-off ship suitable for inland river transport and a vehicle. By the design of wide ratio of water depth, asymmetric double-tail fins, an internal rotation screw propeller and a large outer floating cross section, the inland river passenger transport and vehicle roll-on-roll-off ship are suitable for navigating in an inland river, and convenient to operate. Meanwhile, the large outer floating cross section is also beneficial to providing larger area of the main deck.

Among the figure: ceiling deck 1, saloon deck 2, engine casing upper deck 3, main deck 4, double tail fins 5, bulbous bow 6, springboard 7, upper strata hold 8, lower floor's hold 9.

The specific embodiment

In Fig. 1, the passenger traffic of a kind of inland river and car carrier comprise hull and multideck, and hull under water molded line stem is provided with bulbous bow 7, and described bulbous bow 7 is breakhead formula bulbous bow 7.Afterbody is provided with double tail fins 6; Bulbous bow 7 can reduce the water blockoff phenomenon of high speed boats and ships hull stem.Aspect ratio L/B is little to improve, the residuary resistance performance of inland river ship type when beam draft ratio B/T is large.

In Fig. 1, also be provided with at least one deck saloon deck on the described main deck 5, in Fig. 3, Fig. 4, saloon deck is provided with bridge deck 2 and ceiling deck 1.Be provided with two-layer saloon deck in this example, in Fig. 5, Fig. 6, namely go up saloon deck 3 and lower saloon deck 4.

Such as Fig. 8, shown in Figure 9, be provided with two-layer hold in the described hull, i.e. upper strata hold 9 and lower floor's hold 10.Described hull adopts two side of a ship structures.This structure has improved the safety performance of boats and ships.

In Fig. 7, the main deck 5 in the multideck adopts complete vertical flow-through, and main deck 5 employings are striden greatly girder construction by the transition side wall support without pillar, and described transition sidewall adopts box-structure, and an end of main deck 5 is provided with springboard 8.But main deck is year car deck of passenger vehicle or lorry, and the loading of vehicle is convenient in the design of this structure, thereby has realized passenger, vehicle mixed transportation.The springboard that arranges, the configuration electric winch lifts by crane, transfers by mechanical drive, when springboard and bank base overlap appropriate after the realization vehicle roll dress.

The afterbody of hull is square tail.Described double tail fins 6 is the asymmetric double tail fins of outer splayed.Described asymmetric double tail fin is namely in the place ahead of screw propeller, the shape of tail fin is unsymmetrical, neither rotational symmetry, neither plane symmetry, the bottom of fin is usually large than top, wake is evenly distributed keeps higher average wake, the cross-sectional plane of " peach " in the similar fruit of cross-sectional plane, the top of fin slopes inwardly, and the bottom is outward-dipping.Adopt the tail type of vertical stream between the double tail fins, cooperate the square tail of entry, can reduce again the residuary resistance of afterbody.Square tail after the optimization, bulbous bow and non-symmetric double tail fin ship mould are a high-efficiency low-resistance ship type.Described hull underwater propulsion unit is inward turning screw.Hull under water afterbody adopt square tail and the asymmetric double tail fins of outer splayed, cooperate the large radius-depth of inward turning than screw propeller, both can increase the effect of prewhirling of incoming flow before the oar, can increase diameter of propeller again, thereby make screw propeller be in high wake district.The combination of these structures is suitable in inland waterway navigation the utility model, and easy to operate.

In Fig. 2, Figure 10, Figure 11, described hull floats the bench section adopt greatly from head to tail outside.From Fig. 2, Figure 11, among cross-sectional plane of the present utility model and Figure 10, relatively can the finding out of the cross-sectional plane of inland navigation craft in the prior art, it is large that outer to float design be midship midship section coefficient of the present utility model, adopting alternatively the midship midship section coefficient is 0.8 ~ 0.9.

Midship midship section coefficient in this example is preferably 0.817.The midship midship section coefficient of more conventional inland navigation craft is generally 0.98 little a lot.Thereby enough drafts are arranged, improved the efficient of screw propeller.Both guaranteed to have guaranteed again sufficient year car floor space under the condition of enough carrying capacity requirements.

The utility model is the ship type of steel, Double bottom, two side of a ship, two stern types, spacious main deck adopts the transition sidewall without the pillar box-structure, and the superstructure that forms vertical flow-through is arranged, not only satisfy the structural strength of ro-ro passenger ship, also fully satisfy dissimilar visitor, charge of trucks discrepancy.

Described hull overall length is 130-160 meters, 18-32 meters of molded breadths, 3.6-6 meters of moldeed depth, the designed draft degree of depth 2.5-4.5m.This example ship adopts following size: 132 meters of overall lengths, 23.2 meters of molded breadths, 5.2 meters of moldeed depth, designed draft degree of depth 4.2m.This standard form ro-ro passenger ship demonstrates fully the requirement of " safety, environmental protection, economy, attractive in appearance ", main engine power 2000kw * 2, and Design Speed 28km/h can load 129 small passenger cars or 42 large part cars and 1000 passengers simultaneously.
