Abstract
The invention discloses a kind of bow mozzle device, mozzle device is made up of with the some compressed air tubies be arranged in mozzle the hollow flow-guiding pipe of both ends open, and described mozzle device is arranged on the stem of boats and ships, middle position.The present invention compared to the prior art, the current of fore flow into hull bottom by mozzle device, decrease the resistance that water impact bow produces, save the onward impulse of boats and ships, reduce current simultaneously and damage is bounced to bow, and the air bubble discharged in compressed air tube carries out air lubrication to hull bottom, decrease the friction drag of hull bottom and current, further save the onward impulse of boats and ships.
Description
Technical field
The present invention relates to a kind of guiding device peculiar to vessel, be specifically related to a kind of Guide pipe device for stem.
Background technology
Full formed ship oceangoing ship is when navigating by water, the water flowing to bow can be a lot, a large amount of current easily impact, pat bow, very large resistance is brought to ship's navigation, bounce simultaneously and also easily damage bow construction, and full formed ship oceangoing ship is when navigating by water, hull bottom and water produce larger friction drag, thus bring very large resistance to ship's navigation.
Summary of the invention
Goal of the invention: the object of the invention is to make up the deficiencies in the prior art, provides and a kind ofly by the current deflecting hull bottom of bow, and can reduce the mozzle device of the friction force of hull bottom and water.
Technical scheme: a kind of bow mozzle device, described mozzle device is made up of with the some compressed air tubies be arranged in mozzle the hollow flow-guiding pipe of both ends open, and described mozzle device is arranged on the stem of boats and ships, middle position.
Described mozzle radial direction is Curved, and the entrance of mozzle is arranged on bow designed draft line place, and outlet is arranged on the front end of collision bulkhead.
Described compressed air tube is evenly arranged on the inwall of mozzle, and the distance between adjacent compressed air tube is 3-6 times of compressed air tube caliber.
Described compressed air tube is distributed on the semi arch inwall of mozzle.
Beneficial effect: after present invention employs such structure, the current of fore flow into hull bottom by mozzle device, decrease the resistance that water impact bow produces, save the onward impulse of boats and ships, reduce current simultaneously and damage is bounced to bow, and the air bubble discharged in compressed air tube carries out air lubrication to hull bottom, decrease the friction drag of hull bottom and current, further save the onward impulse of boats and ships.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the lateral plan of accompanying drawing 1.
Detailed description of the invention
Specific embodiment
A kind of bow mozzle device, mozzle device is made up of with the some compressed air tubies 2 be arranged in mozzle 1 the hollow flow-guiding pipe 1 of both ends open, mozzle device is arranged on the stem of boats and ships, middle position, in ship's navigation, the current flowing to bow flow to stern by mozzle device, flow in water, decrease the resistance of current to bow, mozzle 1 radial direction is that flexible bending is curved, avoid generation loss in head, the entrance of mozzle 1 is arranged on bow designed draft line place, and outlet is arranged on the front end of collision bulkhead.Compressed air tube 2 is distributed on the semi arch inwall of mozzle 1, surface is provided with many intensive apertures, be used for releasing air in mozzle 1, air-water mixture is formed in mozzle 1, after air-water mixture flows out mozzle, air bubble floats up to hull bottom, form the air layer of 1 ~ 2 cm thick alow, hull bottom is lubricated.Compressed air tube 2 is evenly arranged on the inwall of mozzle 1, distance between adjacent two compressed air tubies 2 is 3-6 times of compressed air tube 2 caliber, compared to the prior art, the present invention can reduce bow wave making height, reduces the resistance to water-flow of bow, saves the onward impulse of boats and ships, reduce by the resistance of 2 ~ 4%, the intensive air bubble utilizing compressed air tube to discharge carries out air lubrication to hull bottom, reduces the friction drag of hull bottom and water, reduces by the resistance of 2 ~ 4% further.
