Abstract

The invention discloses a deformable ship stem with a flexible air bag. The ship stem is capable of reducing water resistance in ship sailing and improving the sailing speed of a ship, in peculiar to a deformable ship stem with a flexible air bag. The ship stem comprises a ship body, wherein the bottom of the ship body is provided with a bulbstem which is made of flexible materials and comprises the flexible air bag with an inflatable inner chamber; the flexible air bag is fixedly connected to the front end of the bottom of the ship body through a connecting piece; after the flexible air bag is inflated, the shape of the air bag is a stream line which raises to the front of the ship body; the bottom of the ship body is provided with an air inflating and exhausting system for inflating and exhausting air for the flexible air bag; a ship stem door is arranged above the flexible air bag; and the lower end of the ship stem door is hinged on the ship body. The deformable ship stem with the flexible air bag has the advantages of effectively reducing the sailing resistance of the ship, and the sailing speed is promoted, so that the energy consumed in a ship sailing process is reduced; when the ship arrives on a shore, the air is exhausted from the air bag, the air bag contracts, and a space is vacated for the ship stem door, so that the ship stem door is placed down successfully; and the deformable ship stem with the air bag is especially suitable for ferry ships carrying passengers and vehicles or other ships with ship stem doors; and meanwhile, the ship stem is simple, easy and feasible in structure, and low in cost.

Description

Flexible air-bag deformable bow

Technical field

The present invention relates to a kind ofly can reduce the water resistance of boats and ships in advancing, improve the bow of ship speed, a kind of flexible air-bag deformable bow specifically belongs to the shipbuilding field.

Background technology

Car passenger ferry widespread use inland river and coastal, its stem is provided with the gate, and the stem line style of existing car passenger ferry is more fertile, and therefore the boats and ships water resistance is larger in the navigation process, and in same main engine power situation, the speed of a ship or plane is lower.

Have bulb-bowed boats and ships, its bulb-bowed effect is to change the foremost part of ship line style, the wave making resistance when reducing navigation, and ball nose head commonly used is steel structure at present; If it is first in car passenger ferry stem, steel ball nose to be installed, when transferring at ship bank-head section gate, the first meeting of steel ball nose and stem gate generation space interference, and then cause the stem gate to be difficult to put down, the steel ball nose head that therefore, can not be out of shape can't use on car passenger ferry or other have the boats and ships at first gate.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of can the distortion by inflation and venting realization, satisfies to have the flexible air-bag deformable bow that uses on the boats and ships at first gate.

For the flexible air-bag deformable bow that solves the problems of the technologies described above, comprise hull, it is first that the bottom of hull is provided with the ball nose, the first flexible air-bag with inflatable inner chamber for being made by flexible material of ball nose, flexible air-bag is fixedly connected on the hull bottom front end by attaching parts, is shaped as to the streamline contour of hull the place ahead projection after its inflation; Hull bottom arranges the inflating and exhausting system that promising flexible air-bag fills exhaust; The top of flexible air-bag is equipped with the bow gate, and lower end, bow gate is hinged on hull.

Described flexible air-bag comprises an air sac sealing body, and the vent charge that is connected with inflating and exhausting system is set on the air sac sealing body; External the enclosing of air sac sealing is equipped with the connecting portion that is connected with air sac sealing body one, and described connecting portion is connected with a connecting frame, and connecting frame is captiveed joint with hull.

The end of described connecting portion is set to hollow crimping coupling end, and hollow crimping coupling end parcel is connected on the connecting frame of ring-type, and connecting frame is arranged at intervals with the installation end that is connected with hull.

Compared with prior art, advantage of the present invention and effect:

As the boats and ships bow, in the ship's navigation process, the bow after inflation can effectively reduce ship resistance with the deformable flexible air bag, promotes the speed of a ship or plane, thereby reduces the energy consumption in the ship's navigation process; When boats and ships pulled in to shore, air bags was shunk, and was bow gate vacating space, and the bow gate puts down smoothly, is particularly useful for ferryboat or other Ship Types with first gate that car is carried in carrying, this bow construction simple and feasible simultaneously, and cost is low.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, flexible air-bag deformable bow of the present invention is described in further detail.

As shown in the figure, flexible air-bag deformable bow of the present invention, comprise hull 1, it is first that the bottom of hull 1 is provided with the ball nose, the first flexible air-bag with inflatable inner chamber 3 for being made by flexible material of ball nose, flexible air-bag 3 is fixedly connected on hull 1 bottom front by attaching parts, is shaped as after flexible air-bag 3 inflation to any streamline contour that is conducive to reduce ship resistance of hull the place ahead projection; Hull 1 bottom arranges the inflating and exhausting system 4 that promising flexible air-bag 3 fills exhaust; The top of flexible air-bag 3 is equipped with bow gate 2, and 2 lower ends, bow gate are hinged on hull 1.

Wherein, flexible air-bag 3 comprises an air sac sealing body 5, and the vent charge 8 that is connected with inflating and exhausting system 4 is set on air sac sealing body 5; Air sac sealing body 5 peripheries are provided with the connecting portion 6 that is connected with air sac sealing body 5 one, and connecting portion 6 is connected with a connecting frame 7, and connecting frame 7 is captiveed joint with hull 1.

Further the end of connecting portion 6 arranges hollow crimping coupling end 9 can be set, and hollow crimping coupling end 9 parcels are connected on the connecting frame 7 of ring-type, and connecting frame 7 is arranged at intervals with the installation end 10 that is connected with hull 1.

By above-mentioned setting, the present invention with deformable flexible air bag 3 as bow, flexible air-bag 3 can be inflated and bleed by inflating and exhausting system 4, realize distortion, in the ship's navigation process, bow gate 2 rises, 4 pairs of flexible air-bags 3 of inflating and exhausting system are inflated the bow that forms boats and ships, reduce running resistance when realizing ship's navigation, improve the purpose of ship speed, the state as shown in Figure 1 of the state in the ship's navigation process; When boats and ships pull in to shore, drive to the bank suitable distance, 4 pairs of flexible air-bags 3 of inflating and exhausting system are bled, get rid of air in air bag, gas drains rear flexible air-bag 3 and is close to hull 1, and for transferring vacating space in bow gate 2, transfer at bow gate 2, be convenient to vehicles or pedestrians current up and down, boats and ships pull in to shore state as shown in Figure 2.
