Abstract
The present invention relates to a ship, which is suitable for sailing in an ice sea. The present invention comprises a nozzle, a pump and a heater, wherein the nozzle is assembled on an outer plate of a ship body. The pump sucks seawater from a water inlet at the bottom of the ship, and discharges the seawater into the sea from the nozzle. The heater is arranged between the pump and the nozzle, and is used for heating the seawater before the seawater is discharged into the sea. The discharged seawater forms a water layer between a ship shell and floating ice, which reduces friction during sailing and also perform the function of forcibly pushing the floating ice away from the ship body.
Description
The present invention relates to can be under low friction drag, and the boats and ships in the marine navigation of icing or freezing comprise icebreaker more.
Meet obstructions in the process that the boats and ships of described type navigate by water in the marine environment of icing or freezing more.These resistances are because the required power that opens ice, and the friction force between the friction force that navigation produces in seawater usually and hull and the ice that has been broken produces.For the merchant ship that navigates by water in the water of the many ice that opened ice, the friction force of the piece that opens ice is maximum in above-mentioned three kinds of power.
In the prior art relevant for the proposal of eliminating the collision resistance between solid friction resistance or ice and the hull, namely adopt the way that forms a stream layer on the shell surface, make hull only run into the resistance of fluid rather than a kind of resistance of solid property, total drag reduction that the term of voyage hull is run into.For example, among the PCT publication number WO8300850, a kind of icebreaker has adopted with sea intake, and the shell that nozzle is housed on the outside plate and a pump that links to each other with sea intake and nozzle is arranged is so that on shell, namely between ship and ice, form a sea water layer.
An object of the present invention is to provide a kind of boats and ships of the marine navigation freezing, comprise icebreaker.This ship, pushes the ice cube of profile open and form a sea water layer that surrounds whole profile, thereby the resistance when making navigation obviously descends by a kind of simple structure in a kind of efficient mode.
The present invention achieves the above object at the sea going boats and ships of ice by providing a kind of.The hull of this ship comprises: an outside plate that the end of sea intake is arranged and consist of the hull side; Some nozzles that are contained in the outside plate; A pump that connects sea intake and nozzle is in order to suck seawater and enter marine from nozzle from water inlet.Nozzle can be contained in below the sea and direction makes progress, and the seawater of discharging thus will rise along profile, forms an actv. sea water layer.Because the seawer quality of draining is very big, just effectively glacon is pushed open from shipboard.Therefore the seawater of discharging forms one makes the resistance that runs in the ship's navigation be limited to the resistance of fluid along the hull side without any the sea water layer of obvious stretching, extension or diffuse fluid, and its numerical value significantly reduces.
In a perfect embodiment of the present invention, a temperature booster is connected between pump and the nozzle, is used for heating the seawater that is sucked by pump, and used thermal source is positioned at boats and ships inside.The surface that the seawater that heats like this discharges to melt any icing material that contacts with hull by nozzle forms one deck sea water layer thus at an easy rate along the hull side.Thermal source can be the high temperature discharge water that is obtained by ship ship engine cooling, or the steam that receives the ship boiler under High Temperature High Pressure.This makes and adopts a temperature booster to become possibility, the heat energy of the surplus of this temperature booster dependence high temperature discharge water thermal source or the part circulating energy that utilization obtains from steam.Final result is effective utilization of energy and comprehensive minimizing of system dimension.
According to the type of dress thermal source in board, seawater can be discharged by nozzle with the form of hot sea water or with the form of steam.The seawater of discharging with vapor form can warm near the seawater the nozzle by direct contact, discharges hot sea water from nozzle and also obtains same effect.One group of additional nozzle can be installed in the position of above tide on outside plate, and is configured to point to the sea, thereby strengthens the effect of pushing floating ice from shipboard open.The seawater of discharging from this group nozzle does not need heating.
Be lower than in the outboard plate one group of nozzle that is used for discharging to stern seawater also can be installed on the position on sea.This structure will make the backward mobile friction drag that also reduces widely between shell and seawater of floating ice.If have below the sea such arrangement towards above nozzle to produce one shunting towards stern, then effect is almost in opposite directions.
Other features and advantages of the present invention will embody from the explanation that following connection with figures is done.Identical reference symbol shows same or similar part in its whole features in the accompanying drawing.
Brief description of drawings
Fig. 1 is the overall lateral plan of hull that embodies the present invention's boats and ships.
Fig. 2 is that Fig. 1 is along the cutaway view of A-A line.
Fig. 3 is the sketch of one of general structure of temperature booster drawn in the presentation graphs 2 example.
Fig. 4 is another routine sketch of the general structure of temperature booster in the presentation graphs 2.
Being described as follows of most preferred embodiment:
Fig. 1 and Fig. 2 show according to general concrete ship of the present invention.The hull of this ship comprises the end that sea intake 1 is housed.Pump 2 links to each other with water inlet 1, in order to suck seawater.This pump further is connected to downward top nozzle 73 with a prescription with temperature booster 3.
Be the occasion of the high temperature and high pressure steam that obtained by ship boiler at thermal source, shown in Fig. 4 embodiment, temperature booster 3 is a chamber, its inside hold the pipe 5 of one section transmission steam '.In Fig. 3, temperature booster 3 links to each other with pipe 4, pipe 6.Pipe 4 the other end connects pump 2, and pipe 6 links to each other with nozzle 71,72.From the steam of boiler through pipe 5 ', pipe 5 ' guiding steam is by the chamber of temperature booster 3.Vapour cycle is got back to boiler then.Pump 2 sucks seawater from water inlet, and sends it the chamber of temperature booster 3 to via pipe 4.The heat that steam has is passed to seawater in the temperature booster Room 3 by managing 5 wall, and then, seawater is with the form of hot sea water or steam nozzle 71 and reverse flow nozzle 72 under importing one group by pipe 6 under the effect of pump 2.
Said nozzle 71,72, the 73rd is made in the outside plate that consists of profile.Optimal cases as shown in Figure 2 receives from the hot sea water of temperature booster 3 or the lower nozzle 71 of steam via pipe 6, near alow, is directed upwards towards the sea, in order to form direction towards the warm sea water layer of the one deck on sea along profile.Receive reverse flow nozzle group 72 from the hot sea water of temperature booster 3 or steam via pipe 6 and be contained in below the sea shortly past the place on sea, be suitable for spraying hot sea water or steam to stern.In the outside plate of profile, nozzle block 73 is installed in the position that the sea is above.This group nozzle points to the sea downwards, in order to glacon is pushed away hull.In order to reach this purpose, top nozzle 73 directly links to each other with pump 2 by pipe, in order to the seawater ejection of being brought up by pump is gone.Should be noted that top nozzle 73 can link to each other with pipe 6, sprays hot water like that in order to resemble nozzle 71,72.Lower nozzle 71, the position of reverse flow nozzle 72 and top nozzle 73, distribution, number and injection pressure, preferably according in the ship's navigation process because the existence of ice imposes on the friction force distribution of shell selectes.
When ice sea-freight row, seawater is discharged from lower nozzle 71, forms the sea water layer that one deck direction makes progress along profile, simultaneously glacon is pushed away hull.In case of necessity, seawater also sprays from top nozzle 73 to the sea, and floating ice is pushed open from profile.Up and down like this concerted action of nozzle 71,73 is in order to more effectively form a water layer between hull and ice on every side.By discharging simultaneously seawater from reverse flow nozzle 72, can further reduce the resistance that hull is met when the ice Hainan Airlines are capable.In addition, as mentioned above, because the seawater of nozzle 71,72,73 discharges can be heated or be transformed into by temperature booster steam, therefore between hull and ice on every side, can form a water layer in a kind of very effective mode.
Because the present invention can be made into the concrete form that differs widely on many surfaces and not break away from its spirit and scope, therefore, in claims defined, the present invention should be understood to be not limited to special embodiment.
