Abstract

The invention relates to a ship energy-saving bulbous bow. The energy-saving bulbous bow comprises a plurality of bulbous bow housings of different sizes, wherein the smallest bulbous bow housing (3) is fixedly and hermetically assembled with a hull; a bulbous bow housing storage region (1) is arranged on a deck or in a cabin of a bow part, and the rest bulbous bow housings are stored in the region; the bow part is also provided with a manipulator (4); according to the speed and the draft of the ship, the manipulator is used for grabbing the corresponding bulbous bow to assemble and replace on the outer side of the smallest bulbous bow housing (3). By considering the adaptability of the ship and the draft to the size of the ship bulbous bow, the bulbous bow is adjusted into a proper big one when the ship is sailing at high speed and deep draft and is adjusted into a proper small one when the ship is sailing at low speed and shallow draft so as to meet the different sailing requirements.

Description

A kind of ship energy saving bulb bow
Technical field
The present invention relates to a kind of stem of ship, more particularly, to a kind of bulb bow of ship, belong to Ship Design Technology neck Domain.
Background technology
Research both domestic and external have realized that by install additional before hull bulb bow produce wave making emerging with what hull produced Ripple interferes thus reducing the effect that wave making resistance reaches energy-conservation.Bulb bow optimization is in prior art, stem Alignment Design One of a difficult problem.
As is well known, big bulb bow absorbs water to the high speed of a ship or plane and is beneficial to ship domain deeply, but the low speed of a ship or plane but has to shallow draft Greatly harm, vice versa.So in the size design process to bulb bow, needing the drinking water taking into full account ship deep Degree, and speed of a ship or plane situation.
But, for the ship of some species, the speed of a ship or plane changes greatly, and draft also changes greatly, and this results in hull Bulb bow do not adapt to various in the case of energy saving requirement.How to realize the further energy saving optimizing of bulb bow, be this area One technical barrier.
Content of the invention
The technical problem to be solved in the invention is: for the ship of some species, the speed of a ship or plane changes greatly, draft Change greatly, this result in hull bulb bow do not adapt to various in the case of energy saving requirement.
The present invention takes technical scheme below:
A kind of ship energy saving bulb bow, described energy-conservation bulb bow includes several bulb bow cases of different sizes, wherein Minimum bulb bow case 3 and the assembling of hull fixing seal；It is provided with bulb bow case on the deck at stem position or in cabin to deposit Put region 1, remaining bulb bow case leaves in this region；Stem position is additionally provided with mechanical hand 4, according to the speed of a ship or plane of ship, eats Water depth, described mechanical hand captures corresponding bulb bow case and carries out assembling replacing outside minimum bulb bow case 3.
Further, described mechanical hand 4 is hydraulic machinery handss.
Further, it is provided with the hatch door 2 for mechanical hand 4 turnover above bulb bow.
A kind of ship energy saving bulb bow, described energy-conservation bulb bow includes several bulb bow cases of different sizes, wherein Minimum bulb bow case is assembled with hull fixing seal；Remaining bulb bow case is divided into symmetrical two in central fore-and-aft vertical plane Point, it is respectively stored in the both sides that fore-body divides, when operation of ship to the specific speed of a ship or plane, draft operating mode, by drive mechanism Extract the bulb bow case of coupling, by the track on minimum bulb bow, be fed forward, be combined into complete bulb bow, two There is sealing device point junction.
Further, the quantity phase of the quantity of described bulb bow case compound mode corresponding with ship speed and draft With.
The present invention considers the ship's speed and draft adaptability to ship bulb bow size, when ship is in the high speed of a ship or plane, depth Navigate by water during drinking water, bulb bow is tuned into suitably big bulb bow；Navigate by water when ship is in the low speed of a ship or plane, shallow draft, bulb bow is adjusted Become suitably little bulb bow, meet different navigation demands, with scientific and technological development, can memory metal and removable skeleton technology Maturation us all can be helped preferably to realize this function.
The beneficial effects of the present invention is:
1) ship resistance is effectively reduced by wave-making interaction.
2) greatly improve the energy-saving effect of ship's navigation.
3) structure is simple, easy to implement.
Brief description
Fig. 1 is the vertical section line illustration of ship bulb bow, and in figure h represents bulb bow height, and l represents bulb bow length.
Fig. 2 is the cross section line illustration of ship bulb bow, in figure, and b represents bulb bow width.
Fig. 3 is that the mechanical hand corresponding bulb bow case of crawl carries out assembling showing of replacing outside minimum bulb bow case It is intended to.
Specific embodiment
With reference to specific embodiment, the present invention is further described.
Embodiment (one):
Referring to Fig. 3, a kind of ship energy saving bulb bow, described energy-conservation bulb bow includes several bulb bow covers of different sizes Shell, wherein minimum bulb bow case 3 and the assembling of hull fixing seal；It is provided with bulb bow on the deck at stem position or in cabin Case storage area 1, remaining bulb bow case leaves in this region；Stem position is additionally provided with mechanical hand 4, according to the boat of ship Speed, draft, described mechanical hand captures corresponding bulb bow case to carry out assembling more outside minimum bulb bow case 3 Change.
Described mechanical hand 4 is hydraulic machinery handss.
It is provided with the hatch door 2 for mechanical hand 4 turnover above bulb bow.
Referring to Fig. 1-Fig. 2, when ship is in the high speed of a ship or plane, deep drinking water navigation, bulb bow can be changed by Robot actions Case, so that the effectively bulb-bowed length (l) of ship, wide (b), high (h) become big, reaches optimal Bulb bows and hull cooperation, Make wave making resistance minimum, be finally reached energy-saving effect.
Referring to Fig. 1-Fig. 2, when ship navigates by water in the low speed of a ship or plane, shallow draft, bulb bow can be changed by Robot actions Case, the effectively bulb-bowed length (l) of ship, wide (b), high (h) are diminished, and reach optimal Bulb bows and hull cooperation, make Wave making resistance is minimum, is finally reached energy-saving effect.
Due to the difference of the plentiful degree, the speed of a ship or plane and drinking water of ship, bulb-bowed size length (l), wide (b), high (h) want root Determine according to cfd numerical simulation or test.
To sum up, the present invention passes through to change bulb-bowed size length (l) of hull, wide (b), high (h), obtains the ball of optimal size Nose is first and hull mates, and reduces wave making resistance, reaches the effect of energy-conservation.
Embodiment (two):
A kind of ship energy saving bulb bow, described energy-conservation bulb bow includes several bulb bow cases of different sizes, wherein Minimum bulb bow case is assembled with hull fixing seal；Remaining bulb bow case is divided into symmetrical two in central fore-and-aft vertical plane Point, it is respectively stored in the both sides that fore-body divides, when operation of ship to the specific speed of a ship or plane, draft operating mode, by drive mechanism Extract the bulb bow case of coupling, by the track on minimum bulb bow, be fed forward, be combined into complete bulb bow, two There is sealing device point junction.
The quantity of described bulb bow case is identical with the quantity of the corresponding compound mode of ship speed and draft.
Above-mentioned two embodiment adaptability to ship bulb bow size all in view of ship's speed and draft, when ship exists Navigation when the high speed of a ship or plane, deep drinking water, bulb bow is tuned into suitably big bulb bow；Navigate by water when ship is in the low speed of a ship or plane, shallow draft, will Bulb bow is tuned into suitably little bulb bow, meets different navigation demands, with scientific and technological development, can memory metal and removable The maturation of skeleton technology all can help us preferably to realize this function.
