Deformable ship stem with flexible air bag

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

[0001] technical field [0002] The invention relates to a bow capable of reducing the water resistance during the moving of the ship and increasing the speed of the ship, in particular a deformable bow with a flexible air bag, which belongs to the field of ship manufacturing. Background technique [0003] Car-passenger ferries are widely used in inland rivers and coastal areas, and their bows are equipped with gates. The bow of existing car-passenger ferries is fatter, so the water resistance of the ship is relatively large during navigation, and the speed of the ship is relatively low under the same power of the main engine. [0004] For ships with bulbous bows, the function of the bulbous bows is to change the line shape of the bow of the ship and reduce the wave-making resistance during navigation. Currently, the commonly used bulbous bows are steel structures; First, when the bow gate is lowered when the ship docks, the steel bulbous nose will interfere with the bow gat...

[0004] For ships with bulbous bows, the function of the bulbous bows is to change the line shape of the bow of the ship and reduce the wave-making resistance during navigation. Currently, the commonly used bulbous bows are steel structures; First, when the bow gate is lowered when the ship docks, the steel bulbous nose will interfere with the bow gate in space, which will make it difficult to lower the bow gate. For use on ships with the first gate
