Thrust generating apparatus

Technical field

The present invention relates to be arranged at the thrust generating apparatus of the side thruster of the bow end of displacement type ship oceangoing ship or after run, and with the revolving door of its interlock and automatic shutter outside plate opening.

Background technology

Side thruster is to be arranged at the bow of boats and ships or the device that is used to make the ship cross motion of stern.This side thruster is installed on argosy mostly, and especially offshore is pulled in to shore in often the boats and ships such as ferry boat.On the other hand, for little type ship, because operation is relatively easy, or not too effort can make ship move, so installation side is less to angle of rake situation.

But, along with being short of hands and the situation of occupant's aging in recent years, in little type ship, using the requirement of the function of side thruster also to improve.Therefore, real the opening of Japan proposes to have a kind of side thruster in the flat 5-16594 communique, and it makes from the seawater jet flow of the seawater that is used for the clear water cooling mechanism with pump, produces propulsive force thus.

Patent documentation 1:(Japan) open flat 5-16594 communique in fact

When using various boats and ships; the environmental protection and the saving energy become unavoidable big problem with the development of few sonization, aging society; at occupant's aging, economize under peopleization, the international situation, in the ship simplification of various operations, safety guarantee obtain attention gradually.Especially under province's energy of the boats and ships self that turn to main body with main frame tool electronic and situation that high performance becomes important topic, device of the present invention provides a kind of be easy to technically realize offshore the pull in to shore simplification of operation, the side thruster of rationalization.

At above-mentioned problem, proposition has utilization seldom to compress the jet flow of the sea water pump on the ship of ship valency and obtains the method for thrust, but, the high capacity head of pump is also bigger generally speaking, randomly high-revolving jet flow being discarded to marinely also can become eddy current, can not bring into play thrust as required counter-force, only rely on its water column surpass around seawater viscosity and slide and simultaneously in the unlimited seawater zone under hydrostatic pressure diffusion disappear, actv. thrust can not be provided.

The initial motion of the big more rotation of resistance of desiring the displacement hull that makes it to move in this phenomenon is difficult more, thereby can't realize practicability.

In addition, for the thrust of the side thruster of displacement type ship oceangoing ship, be not requirement its at a high speed, but require under dead slow speed, can obtain big thrust effectively.One of problem of the present invention is that the ejection current of sea water pump that diameter is little are transformed to large diameter current.Be that purpose is to discharge effectively the general angle of rake current that are similar to practical diameter under certain output.

On the other hand, but the screw propeller with reverse thrust generation function that common side thruster utilization is disposed in the pipeline that connects port and starboard produces thrust, and originally side thruster being arranged at as far as possible the bow leading section is favourable for obtaining bow tailspin commentaries on classics thrust then.

But,, promptly be used to make a complicated grade that is of screw propeller rotation and the restriction in the interior configuration of ship owing to device single-piece size, have to side thruster is arranged at position near the hull parallel portion, thus, the length of pipeline will surpass necessary length, thereby causes thrust to descend.Therefore, if move in the aperture position of side thruster pipeline gangway is had an angle of incidence on floating line the place ahead, then the resistance of hull can increase, and can cause the inflow of other objects.Therefore, if protective device is set, then can cause the resistance of passage self to increase in gangway openings at two ends portion.Above-mentioned situation is no exception to quarter of a ship, because these restrictions make side thruster be difficult to be configured in only position.

In addition, about thrust generation direction,, may realize just have only, but its enforcement can bring the complicated problem of mechanism by the rotating screw main body in order all to obtain the thrust that equates in positive and negative any one direction.

In addition, the angle of rake wake flow of propeller type can become eddy current, and specific efficiency is lower mutually with the straight feed water flow of the jet flow of general-purpose pump.

bracket

45a, 45b, 46 bunchiness are connected in bar 18, and thus, revolving door 15 is fixed in locked position of coupler, and nozzle 12 is fixed in the reception position 38 on the hull line of centers.

From above-mentioned state (position during navigation) when entering the mooring operation, bar 18 is promoted to position 48 among Figure 18.So the bracket 46 that is fixed in the vertical component effect 11 of bleed pipe can left rotation and right rotation, and be positioned at bracket 45a, the 45b of the position of the path part 49 that is arranged at bar 18 can be to the opposite sense rotation of the open sides of the notch 51 that is arranged at its perforate 50.Thus, revolving door 15 can be towards side of a ship rotation separately.Therefore, the revolving door 15 that nozzle 12 rotates any side of a ship of a side is promoted by this nozzle 12 and rotates, when after the rotation bar 18 being depressed, and can be fixing to the revolving door 15 of side board by the large-diameter portion 52 of bar.

In addition, the relation of the perforate 50 of the large-diameter portion 52 of bar 18, minor diameter part 49 and

bracket

45a, 45b, notch 51 is as described below.That is, the diameter of large-diameter portion 52 is littler than the diameter of perforate 50, but bigger than the width H (Figure 10) of notch 51.The diameter of minor diameter part 49 is littler than width H.

In addition, fix in the time of for nozzle 12 and two side of a ship revolving doors 15, by above-mentioned operation, revolving

door

15,15 is via

bracket

45a, 45b and bar 18 and become one, therefore, the revolving door that utilizes two sides of a

ship block

44,44 separately stops rotation to the left and right and finishes to rotate, but by utilizing countersunk-heat bolt (not shown) in the handle 19 on the work deck etc. to fix, can form safety device thus.

For the argosy that exceeds above-mentioned embodiment, need make rotating operation lighter.For this point, owing to do not have moving part on the nozzle, therefore part or all that is easy to nozzle is made of plastic, and, by revolving door is made as square, and at four jiaos above-below direction the sea water resistance castor is set, and for the rigidity of strengthening revolving door in the air vessel of revolving door injecting plastics etc., all easy to implement.

In addition, in order to realize maximizing, needing to increase capacity of pump causes the ship valency to rise, but, as shown in Figure 1, if the boiler check valve 53b of the boiler check valve 53a of induction pipe side and bleed pipe side is ended valve as plug, and connect clear water pipe 54 and clean sea water pumps 4, then can under the situation that does not reduce durable years, control cost and use the general-duty clarified water pump in a side of said pump.

Along with the ship type strengthens, the size of propelling unit chamber also can increase.For this situation, can prolong by prolongation ring 13, and the measures such as length expansion of nozzle 12 self are dealt with nozzle 12.In addition, as shown in Figure 3, be under the situation of U type 61 or V-type 62 in bow portion section ship type, also can profit use the same method and deal with.

In addition, in order to avoid contacting the revolving door near zone of the canoe that uses the mooring rope at the bow afterbody of mooring operation etc., especially in order under the medium situation of muddy water at night, to observe the floating line near zone, therefore near the working lamp work deck side of a ship end etc. is to cover the watertight cover that toughened glass is made on the white dome-type toughened glass system reflection sphere of light source or the luminary 59 that does not need power wiring with light, and be installed on the door directly over and hull end floating line near, thus, can improve near the bow tail end that has comprised the side thruster that revolving door and outside plate are difficult to differentiate safety.

In addition, though embodiments of the present invention mainly are to be illustrated as bow thruster, as shown in figure 22, can utilize the sea water pumps in the Machine Room 73 and to directly apply to the situation of quarter of a ship 72 also a lot.

In addition, under the smooth situation of hull bottom such as shallow draft, expanded letter ship, also can pass through application engineering scheme 5 and technical scheme 6 described inventions, and nozzle 12 is overhang hull bottom deal with.

Below its details is described.Among Figure 21, half fusiform guard shield 6 is used to put in order the current in the outside of the bleed pipe 11 that hangs bell shaped nozzle 12 and use as rudderpost, to be provided as the horizontal profile of rudder face be fleetline empennage 66 in the bottom thereon, and integral body becomes the area distributions that plays the balanced rudder effect.

Bleed pipe vertical component effect 11 is positioned at steering gear compartment 67 bottoms, utilizes the vertical power of bearing 68 corresponding horizontal directions and floating up and down, and be provided with at an upper portion thereof can 360 degree rotations steering engine 69.In addition, said apparatus can utilize the prior art of practicability.

In addition, above the bleed pipe vertical component effect 11 that uses as rudderpost, be set to bleed pipe 10, and keep the water tightness of connecting portions by seal closure 70 with the fixing pipe arrangement of sea water pump 4.

According to this device, as shown in figure 22, except the function of performance as the side thruster of quarter of a ship, also can migrate and make propelling unit, under this situation, the wake gain that utilizes the expansion of discharging jet and advance along with hull is appended in the rear end in order further to obtain thrust the ring 71 with aerofoil profile is set.

In addition, a plurality of these devices that comprise sea water pump are installed according to the ship type, and the expansion of the ability by the electric motor driven pump of convertor controls etc., be easy to increase thrust.
