Abstract
The utility model discloses a stem flow guiding pipe device which comprises a hollow flow guiding tube with openings at two ends and a plurality of compressed air pipes arranged in the flow guiding tube. The flow guiding tube is arranged in the middle head portion of a ship. Compared with the prior art, water flow of a ship head flows into the bottom of the ship through the flow guiding tube, resistance produced by a manner that the water flow shocks the stem is reduced, forward motive power of the ship is saved, and at the same time panting damages to the stem from the water flow is reduced. And air bubbles released from the compressed air pipes lubricate the bottom of the ship with airs, and therefore frictional resistance between the bottom of the ship and the water flow is reduced, the forward motive power of the ship is further saved.
Description
Technical field
The utility model relates to a kind of guiding device peculiar to vessel, is specifically related to a kind of bow mozzle device.
Background technology
The full formed ship oceangoing ship is when navigation, the water that flows to bow can be a lot, a large amount of current easily impact, pat bow, bring very large resistance to ship's navigation, bounce simultaneously and also easily damage bow construction, and the full formed ship oceangoing ship is when navigation, the friction drag that hull bottom and water generates are larger, thus very large resistance brought to ship's navigation.
The utility model content
The utility model purpose: the purpose of this utility model is in order to remedy the deficiencies in the prior art, provide a kind of can be with 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 comprised of the hollow flow-guiding pipe of both ends open and the some compressed air tubies that are arranged in the mozzle, and described mozzle device is arranged on the stem of boats and ships, middle position.
Described mozzle radially 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 evenly is arranged on the inwall of mozzle, and the distance between the 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: the utility model has adopted after such structure, the current of fore flow into hull bottom by the mozzle device, reduced the resistance that the water impact bow produces, saved the onward impulse of boats and ships, reduce simultaneously current to the damage of bouncing of bow, and the air bubble that discharges in the compressed air tube carries out air lubrication to hull bottom, reduce the friction drag of hull bottom and current, further saved the onward impulse of boats and ships.

The specific embodiment
Specific embodiment
A kind of bow mozzle device, the mozzle device is comprised of the hollow flow-guiding pipe 1 of both ends open and the some compressed air tubies 2 that are arranged in the mozzle 1, the mozzle device is arranged on the stem of boats and ships, the middle position, in the ship's navigation, the current that flow to bow flow to stern by the mozzle device, flow in the water, reduced the resistance of current to bow, mozzle 1 radially is that flexible bending is curved, avoided the 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, the surface is provided with many intensive apertures, be used for releasing air in the mozzle 1, in mozzle 1, form air-water mixture, air bubble floated up to hull bottom after air-water mixture flowed out mozzle, form alow the air layer of 1～2 cm thick, hull bottom is lubricated.Compressed air tube 2 evenly is arranged on the inwall of mozzle 1, distance between adjacent two compressed air tubies 2 is 3-6 times of compressed air tube 2 calibers, be compared with existing technology, the utility model can reduce bow wave making height, reduces the resistance to water-flow of bow, saves the onward impulse of boats and ships, reduce by 2～4% resistance, the intensive air bubble that utilizes compressed air tube to discharge carries out air lubrication to hull bottom, reduces the friction drag of hull bottom and water, further reduces by 2～4% resistance.
