Abstract
A bubble drag reduction ship for inland rivers adopts the characteristics of a longitudinal flow ship, can enable most of water flow to longitudinally flow along the bottom of the ship, is combined with a bubble transmission pipeline in a buoyancy cabin, bubbles are generated below a longitudinal flow ship body and rise to the bottom surface attached to the longitudinal flow ship body through self buoyancy under the condition of overcoming water pressure, and an air layer is formed on the bottom surface of the longitudinal flow ship body so as to reduce the friction between the bottom surface of the longitudinal flow ship body and water in the sailing process and reduce the frictional resistance, so that the longitudinal flow ship body has small resistance and low energy consumption in sailing; and because the waves are smaller than those in the ocean when the ship body sails in the inland river, the generated bubbles can be effectively ensured not to be easily dispersed, the low-energy-consumption operation of the bubble drag reduction ship on the inland river is further ensured, and the low-carbon sailing on the inland river is realized.
Description
Technical Field
The utility model relates to a bubble drag reduction ship for inland river.
Background
The inland river has the characteristics of certain water flow speed, small rolling motion amplitude of the ship and shallow water depth, and when the ordinary ship runs on the inland river, the water flow resistance is large, so that the energy consumption is large when the ship advances, and low-carbon shipping can not be realized.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a bubble drag reduction ship for inland river that resistance is little, the energy consumption is few.
A bubble drag reduction ship for inland river, including indulging a class ship body, be provided with a plurality of buoyancy cabins along perpendicular captain direction in the bottom of indulging a class ship body, all be provided with to indulging a class ship body below gassing and make the bubble attach to the bubble transmission pipeline of indulging a class ship body bottom surface in every buoyancy cabin inside or outside.
The utility model discloses a bubble drag reduction ship for inland river, adopted the characteristics of longitudinal flow ship, can make most rivers vertically flow along the hull bottom, combine the bubble transmission pipeline in the buoyancy cabin simultaneously, the bubble produces and rises to adhering to on the bottom surface of longitudinal flow ship body through self buoyancy under the longitudinal flow ship body and overcoming water pressure's the condition, form the air bed on the bottom surface of longitudinal flow ship body to reduce the bottom surface of longitudinal flow ship body and the friction of water in the course of sailing, reduce frictional resistance, thereby make the longitudinal flow ship body when sailing resistance little, the energy consumption is few; and because the waves are smaller than those in the ocean when the ship body sails in the inland river, the generated bubbles can be effectively ensured not to be easily dispersed, the low-energy-consumption operation of the bubble drag reduction ship on the inland river is further ensured, and the low-carbon sailing on the inland river is realized.

Detailed Description
A bubble drag reduction ship for inland rivers, as shown in fig. 1 to 3, includes a longitudinal flow ship body 1, a plurality of buoyancy tanks 2 are arranged at the bottom of the longitudinal flow ship body 1 along the direction perpendicular to the ship length, and a bubble transmission pipeline which generates bubbles 7 below the longitudinal flow ship body 1 and enables the bubbles to be attached to the bottom surface of the longitudinal flow ship body 1 is arranged inside or outside each buoyancy tank 2. The longitudinal flow ship body 1 is in the prior art, and is characterized in that the head and the tail of a ship body are provided with a relatively long inflow section and a relatively long outflow section, no obvious contraction of the width of the ship exists at the head and the tail of the ship body, the head of the ship body is a flat head instead of a pointed head, and the bottom surface of the ship body is a flat bottom. Normally, the bubble transferring pipes are all arranged inside the buoyancy compartment 2, which has the advantage of not increasing the additional resistance of the longitudinal flow ship body 1, but is inconvenient for maintenance, so that one or more bubble transferring pipes in the buoyancy compartment can be arranged outside the buoyancy compartment according to actual conditions to increase the convenience of maintenance.
The bubble transmission pipeline comprises an air conveying pipe 3 arranged along the length direction of the longitudinal flow ship body 1, a plurality of air outlets are longitudinally arranged on the air conveying pipe 3, an air faucet is arranged on each air outlet, and the air faucet extends to the lower portion of the bottom surface of the longitudinal flow ship body 1. Air delivery pipe 3 and the air compressor intercommunication of placing on the ship body 1 of indulging the class, through air compressor to air delivery pipe 3 in air delivery pipe and form the bubble to discharge bubble to the ship body 1 below of indulging the class through the air cock, can be attached to on the bottom surface of the ship body 1 of indulging the class when guaranteeing that the bubble floats.
The buoyancy chambers 2 are separated by watertight partition bulkheads 4 and the air transfer pipes 3 are externally enclosed by watertight protective walls 5 to prevent water from entering the hull. The watertight partition bulkhead 4 and the watertight protective wall plate 5 are both plates with a watertight sealing function, and both belong to common sealing technical means in the field of ships.
The bottom section line 6 of the buoyancy chamber 2 is in an upwardly arched shape to ensure that the generated bubbles can move along the upwardly arched structure to be uniformly attached to the bottom surface of the entire longitudinal flow ship body 1. The linear radian of the bottom section of the buoyancy chamber 2 needs to be calculated according to the actual ship body, such as: part of curve segments on a commonly used NACA blade profile section of a ship rudder blade design can be intercepted; or adopting a parabolic line type, and determining the camber of the parabolic line type according to CFD calculation and model test. The most reasonable arc line type is obtained through the method, so that the problem that generated bubbles cannot be uniformly distributed on the bottom surface of the whole longitudinal flow ship body 1 due to too fast or too slow flowing is avoided, and the small resistance and the low energy consumption of the bubble drag reduction ship during navigation are further ensured.
