The utility model content

Technical problem to be solved in the utility model provide a kind of safe, stable, running resistance is little, energy-saving and emission-reduction, the shipbuilding cost is low and not sprayed by a kind of metal air cushion of dead-weight capacity restriction reclaims ship structure.

In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:

A kind of metal air cushion sprays and reclaims ship structure, comprises hull, and described hull midships section is made up of at least two individually balanced gas cabin, and the bottom in each gas cabin is an open ports; Also be provided with nozzle and the cylinder that is connected at described hull midships section, described nozzle and each gas cabin flush fit.

Described gas bilge portion open ports planimetric position is than the bottom water horizontal line height of hull.

The both sides side plate of described hull extends beyond the bottom-open mouth plane in gas cabin downwards.

After the utility model adopts said structure, compared with prior art have following advantage:

(1) thoroughly changed the existing ship design concept, a kind of new Ship Design Technology is provided.

(2) adopt the gas cabin carrying of lower open mouth to design, significantly reduced hull weight, reduce production costs; Can significantly reduce simultaneously the area of contact of hull bottom and water, reduce the viscous resistance of water, reduce energy resource consumption.

When (3) moving on the hull,, make the good stability of hull, safely, be difficult for turning over side, can satisfy the needs of various dead-weight capacityes because of the air in many gas cabin structure has adsorption to glassware for drinking water.

(4) shallow draft of gas cabin carrying, speed-raising is easy, and the speed of a ship or plane is fast, and the course wave is little.

(5) effect of cylinder: accumulation stores the gas of certain pressure in cylinder.

(6) effect of nozzle: by cooperating with cylinder, air pressure and air communication are crossed nozzle ejection hull are produced impetus forward; Air pressure and air communication are crossed nozzle and are reclaimed in the independent gas cabin of each band extension of midships section alow, form unified synchronously stable air cushion layer, and hull has been played stable air supporting effect.

(7) in a word, spray, it plays the effect that hull moves forward that promotes.Reclaim: it makes the gas cabin of hull produce the saturated air bed course, produces hull air supporting effect; Air supporting has changed the proportion of hull, helps the utilization of plant capacity, energy-conserving action; Increase the physics slip inertia of hull, thereby increased the sliding force of hull, the utilization of favourable plant capacity, energy-conserving action.Promptly spray, reclaim and play the multifunctional effect of a gas.

After the detailed description of reading embodiment of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.
