Description
Technical field
The utility model relates to technical field of ships, is specifically related to the new Panama Container Ships line style of a kind of low speed of a ship or plane high energy efficiency.
Background technology
After financial crisis outburst in 2008; American-European Main Developed Countries consumption demand falls sharply; freight container sea-freight amount significantly glides; Central European, Sino-US container marine line takes the lead in implementing boats and ships and slows down; the speed of a ship or plane drops to 12-18kn (joint; in the sea/hour) left and right; Maersk and shipping federation CKYH the biggest in the world (member comprises COSCO, k line, YML, Hanjin Shipping) pass through to reduce ship's speed; to change the situation of freight container transport power surplus, reduce fuel oil consumption and stablize firmly market.In addition, along with IMO (International Maritime Organization's (English: InternationalMaritimeOrganization)) continuous appearance of new regulation and the compulsory execution of boats and ships Energy design index E EDI (EnergyEfficiercyDesignIndex abbreviation), various ships all starts reduction of speed navigation, strive the requirement meeting EEDI, reduce the speed of a ship or plane and become secular trend.
The Panama Canal connects the Pacific Ocean and the Atlantic Ocean, it is important navigation channel, it shortens the voyage of between two ocean 5500 to 10000 nautical miles, shorten the voyage of between east, North America, two sides, west 7000 to 8000 nautical miles, shorten the voyage of between Asia to Europe 4000 to 5000 nautical miles, canal carries the trade shipping in the whole world 5% every year.From Chinese Water Transportation to the U.S., the Panama Canal is must through course line.In recent years, the Panama Canal is widened, within 2007, this canal ship lock is by the ship by long 366m, wide 49m, drinking water 15.2m, this will reduce the cost of China to East Coast of the United States shipping products greatly, meanwhile, widening of the Panama Canal also produces major transformation by the hull lines design of Panamax.In addition, be the situation that reply home-trade amount constantly rises, nowadays the boats and ships throwing in Panamax size in internal trade course line are selected in a lot of coastal area of china acknowledgement of consignment commercial city.
The new Panamanian box ship of exploitation low speed flying height efficiency is by significant and wide market outlook.
Utility model content
In order to solve the technical matters of above-mentioned existence, the utility model provides a kind of low speed of a ship or plane high energy efficiency new Panama Container Ships line style.
The utility model for the adopted technical scheme that solves the problem is: the new Panama Container Ships line style of a kind of low speed of a ship or plane high energy efficiency, comprise bow and the stern of boats and ships, described bow is to midbody, the section of at least 1/2 long hull is " U " type cross section, described stern is to midbody, the section of maximum 1/2 long hull is " V " type cross section, and the section of the ship length namely outside bow " U " type cross section is " V " type cross section.
Further, described bow comprises stem, and described stem is straight stem.
Described boats and ships bow abandons the large ball bow of conventional container ship, adopt section to be " U " type, and stem is the design of straight stem, so can be convenient to the smooth loading of freight container.Described stern section is " V " type cross section, and it is conducive to the viscous pressure resistance reducing boats and ships.
Further, the bottom wheel profile of described bow is vertical stream line pattern, and this line style is conducive to ballast for cruising and eats subsurface water current advance, and boats and ships bow front can be avoided to form whirlpool, thus the enforcement affecting boats and ships is advanced.
Further, described stern is provided with ball tail, and the stern trimming flag outline line slope above described ball tail is 15 ° ~ 22 °.
Further, described stern trimming flag outline line slope is 19 °.
Described stern trimming flag outline line slope is comparatively large, and it is conducive to stern dispersion of flow, avoids forming whirlpool below stern trimming flag, makes the eddy resistance produced due to whirlpool hinder moving ahead of boats and ships.
The beneficial effect that technical scheme described in the utility model is brought is: the new Panama Container Ships line style of low speed of a ship or plane high energy efficiency described in the utility model, boats and ships bow section is adopted to be " U " type, stern section is the new design of " V " type, the speed of a ship or plane of whole boats and ships is made to be reduced to 14 joints by 20 joints of routine, and the resistance that moves ahead is low, propulsion coefficient is high, especially, bow adopts straight stem, the bottom profile of bow is vertical stream line pattern, make boats and ships bow be more prone to loading container, and not easily form whirlpool; Further, the stern trimming flag outline line slope of stern is comparatively large, avoids ship stern and forms whirlpool, for the Panama Canal provides a kind of new herbicide.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is further described.
As shown in Figure 1, provide a kind of low speed of a ship or plane high energy efficiency new Panama Container Ships line style, it comprises bow 1 and the stern 2 of boats and ships, bow 1 place is designed with straight stem 11, at stern 2, place is designed with ball tail 21, is designed with stern trimming flag 22 above ball tail 21, and the outline line slope of this stern trimming flag 22 is 19 °.
As shown in Figure 2, boats and ships bow 1 cross-section structure line design is " U " type structure; Shown in C point, horizon is the design load water line of these boats and ships, along the station track for these boats and ships that design load water line distributes to the left and right sides, each station track near design load water line is almost perpendicular line, bow " U " type structure is in conjunction with the design of straight stem, the vertical branch in hull bench section is more straight, be conducive to the utilization of hold space, be convenient to loading container.
As shown in Figure 3, boats and ships bow 1 side-looking structure lines are designed to vertical stream line pattern, wherein the nadir a distance horizontal base line height of straight stem 11 is H, straight stem 11 is L apart from the spacing of horizontal base line and vertical sweep outline intersection point b, wherein L=13.85m, H=7.3m, this boats and ships bow is indulged between fleetline L/H=1.5 ~ 2
As shown in Figure 4, ship stern 2 end face structure line design is " V " type structure; Can effectively reduce hull wetted surface area, thus reduce friction drag, be conducive to again reducing body prismatic coefficient after boats and ships, move after making fluid boundary layer separation point, thus interlayer stall spot is reduced, viscous pressure resistance decline.
As shown in Figure 5, its outline line slope ratio of stern trimming flag 22 that ship stern 2 is positioned at above ball tail 21 is comparatively large, is conducive to the diffusion of rear current, avoids forming whirlpool at ship stern.From the viewpoint of energy, forming whirlpool at boats and ships afterbody needs hull constantly to provide energy, and the loss of this part energy shows with the form of viscous pressure resistance, so, avoid whirlpool to be also conducive to the reduction of viscous pressure resistance.
The new Panama Container Ships line style of the utility model low speed of a ship or plane high energy efficiency, its speed of a ship or plane is 14 joints, and the more close ship type of its resistance that moves ahead reduces about 4%, and propulsion coefficient improves about 5%.This ship EEDI is 5.941, and the baseline value 16.61 specified than IMO is low by 64%, meets the requirement that EEDI specifies.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
