Abstract

The utility model discloses a bow and particularly relates to a deformable flexible air bag bow which can reduce water resistance in the navigating process of a vessel and improve navigational speed of the vessel. The deformable flexible air bag bow comprises a vessel body, a bulbous bow is arranged at the bottom of the vessel body, and the bulbous bow is a flexible air bag which is made of flexible material and provided with an inflatable inner cavity. The flexible air bag is fixedly connected at the front end of the bottom of the vessel body through a connecting piece. The inflated flexible air bag is in a streamline shape and protrudes toward the front of the vessel body. A filling and air discharging system is arranged at the bottom of the vessel body and used for filling and discharging air in the flexible air bag. A bow gate is installed above the flexible air bag. The lower end of the bow gate is hinged to the vessel body. The deformable flexible air bag bow has the advantages that the navigation resistance of the vessel can be effectively reduced, the navigational speed is increased, and therefore, energy consumption in the navigating process of the vessel is reduced; when the vessel is in shore, the air in the air bag is discharged and retracted so that space can be made for the bow gate, and the bow gate is dropped smoothly. The deformable flexible air bag bow is particularly suitable for ferries carrying passengers and vehicles or other vessels with bow gates. Meanwhile, the bow is simple and practicable in structure and low in cost.

Description

Flexible air-bag deformable bow

Technical field

The utility model relates to a kind ofly can reduce the water resistance of boats and ships in advancing, and improves the bow of ship speed, and specifically a kind of flexible air-bag deformable bow 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 fertile, and therefore the boats and ships water resistance is bigger in the navigation process, and under 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 at present is steel structure; If in car passenger ferry stem steel ball nose head is installed, then pull in to shore the stem gate when transferring at boats and ships, steel ball nose is first can the space interference to take place with the stem gate, 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 at car passenger ferry or other boats and ships with first gate.

Summary of the invention

The technical problems to be solved in the utility model provides 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, the bottom of hull is provided with ball nose head, 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 the hull.

Described flexible air-bag comprises an air sac sealing body, and the exhausr port that fills 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 the 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 is bow gate vacating space, and the bow gate puts down smoothly, is particularly useful for ferryboat or other Ship Types that has first gate that car is carried in carrying, this bow construction simple and feasible of while, and cost is low.

The specific embodiment

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

As shown in the figure, flexible air-bag deformable bow of the present utility model, comprise hull 1, the bottom of hull 1 is provided with ball nose head, 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 any streamline contour that is conducive to reduce ship resistance to hull the place ahead projection after flexible air-bag 3 inflations; 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 the hull 1.

Wherein, flexible air-bag 3 comprises an air sac sealing body 5, arrange on the air sac sealing body 5 be connected with inflating and exhausting system 4 fill exhausr port 8; Air sac sealing body 5 outer periphery are equipped 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 utility model with deformable flexible air bag 3 as bow, flexible air-bag 3 can be inflated and bleeds 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 the air bag, gas drains back flexible air-bag 3 and is close to hull 1, transfers vacating space for bow gate 2, and transfer at bow gate 2, it is current up and down to be convenient to vehicles or pedestrians, and boats and ships pull in to shore state as shown in Figure 2.
