Abstract
A high-speed ship features that a special propeller is equipped int unnel formed at the bottom of hull and the enclosed tail of the tunnel is at least 5 cm lower than floating line of empty ship but higher than the enclosed front end of the tunnel.
Description
The present invention relates to boats and ships, the particularly line style designing technique of boats and ships hull, relating in particular to can be in the more shallow inland river of drinking water or the boats and ships of the high-speed type of the worn-out water propeller device used of ocean shallow water area shipping.
During ship design is at home and abroad in recent years made, because many coastal harbors and river course, inland river are subjected to the shallow restriction of water, large ship, the particularly ton boats and ships unloading that all can't sail into the harbour need be lightered transfer by canoe, has a strong impact on development coastal and the inland water transport industry, if will build the superport harbour, then expensive big, the cycle is long, and it is slow to take effect.Cruiseway is because water is shallow, and cruising range only accounts for the seldom part of national river length overall, if will build railway, highway, then needs to invest a huge sum of money, takies a large amount of soils and valuable good farmland again.Best approach is a development of water transport, its small investment, instant effect.The general employing of conventional boats and ships line style design tail propulsion mode, when the designer satisfied propelling unit the best drinking water design, the hull form designed draft can't satisfy the requirement of travelling in the navigation channel deeply.If the design drauht is more shallow, the best effect that advances of propelling unit blade out of reach, also surface easily, then influence propulsion coefficient and maneuvering performance, boats and ships for the tail tunnel type tail end propulsion mode of routine, because its tunnel design length is subjected to the restriction of marine engine position, afterbody tunnel length is restricted, cause the tunnel buttock line short and steep, curvature change is bigger, to make the current after the propelling unit work be subjected to ponding, and aggravated the disorder of stern propelling unit ambient water, for above-mentioned reasons, make all kinds of tail tunnel type ship oceangoing ships fail in shallow water area and shallow water cruiseway, to be widely used, thereby can't in shallow draft waterway, bring into play the advantage of water transport transportation.
Chinese patent " W type tunnel body fleetline boats and ships " (CN87103815), to be hull elevation profile line style be W shape line style (and can adopt double-enclosure formula twin tunnel) to the characteristics of this patented technology in the hull length overall is made as station, 1.5 station to 6 scope at 10 stations, and propelling unit is positioned at the tunnel scope.Its advantage is obviously to improve conventional boats and ships line style and improve propulsion coefficient, has overcome the shortcoming of tail tunnel type ship oceangoing ship, mainly is applicable to the ultra shallow draft vessel as the rapids and shoals in general shallow draft waterway and various river courses.Its shortcoming is that the afterbody enclosed point yardstick of this W type ship oceangoing ship does not determine that promptly hull afterbody enclosed point yardstick does not clearly provide its yardstick underwater, thereby impacts for manufacturing and designing of boats and ships.
The objective of the invention is and to do further to improve to above-mentioned prior art, automatically arrange the principle of taking out method and/or vacuum suction method and producing the vacuum self-priming when adopting propelled at high velocity, solve above-mentioned W shape line style afterbody enclosed point yardstick and do not have problem identificatioin, thereby design a kind of high-speed ship of spacious water propeller device, make it to help further improving the propulsion coefficient of boats and ships, improve stability, road-holding property and the navigability of boats and ships simultaneously.
