Ship structure

Abstract

A ship structure includes a ship hull formed of independently inflatable left and right garboard strakes, left and right side strakes, a floor plate and upper stretcher plates connected between the left and right side strakes, a portable box arranged at the rear side of the ship hull, a drive unit steering control motor mounted at a mount of the portable box, a rotary wheel supported on the mount of the portable box and rotatable by the drive unit steering control motor, a drive unit supported on the rotary wheel, a propeller suspending outside of the ship hull and rotatable by the drive unit to propel the ship hull on water.

What the invention claimed is: 
     
         1 . A ship structure comprising a ship hull, said ship hull comprising left and right garboard strakes arranged at a bottom side, left and right side strakes symmetrically arranged at opposing left and right sides, a plurality of connection strips joining said left and right garboard strakes and said side strakes, and a floor plate horizontally connected between said left and right side strakes and suspending above said left and right garboard strakes, said left and right garboard strakes and said side strakes being inflatable fabric plate members each comprising two cover layers peripherally sealed, an air chamber surrounded by the peripherally sealed cover layers, and a plurality of fiber strips evenly distributed in said air chamber and connected between said two cover layers. 
     
     
         2 . The ship structure as claimed in  claim 1 , wherein said left and right garboard strakes are joined together, forming a bottom shell of the ship hull, said bottom shell having a substantially V-shaped front part for breaking the waves and a flat rear part for floating on water. 
     
     
         3 . The ship structure as claimed in  claim 1 , wherein said ship hull further comprises a lower stretcher plate horizontally connected between said left and right side strakes at a front side above said floor plate, and an upper stretcher plate horizontally connected between said left and right side strakes and spaced above said lower stretcher plate, said upper stretcher plate defining an opening for the mounting of a cabin, said upper stretcher plate and said lower stretcher plate being inflatable fabric plate members each comprising two cover layers peripherally sealed, an air chamber surrounded by the peripherally sealed cover layers, and a plurality of fiber strips evenly distributed in the air chamber and connected between the two cover layers. 
     
     
         4 . The ship structure as claimed in  claim 1 , wherein the air chambers of said left and right garboard strakes and said side strakes are respectively filled with a foam material. 
     
     
         5 . The ship structure as claimed in  claim 1 , further comprising a portable box arranged at a rear side of said ship hull, said portable box comprising a mount disposed on the outside, a drive unit steering control motor mounted at said mount of said portable box, a rotary wheel supported on said mount of said portable box and rotatable by said drive unit steering control motor, a drive unit supported on said rotary wheel, a propeller suspending below said mount of said portable box outside of said ship hull and rotatable by said drive unit to propel said ship hull on water. 
     
     
         6 . The ship structure as claimed in  claim 5 , wherein said drive unit comprises a cowling cowl, a fuel injection engine mounted inside said cowling cowl, a control unit, an air compressor operable by said fuel injection engine subject to the control of said control unit, and a pneumatic motor rotatable by said air compressor; said ship hull is equipped with a plurality of high pressure gas cylinders, said high pressure gas cylinders being accommodated in between said left and right garboard strakes and said floor plate for storing the high pressure gas produced by said air compressor and inflating the air chambers of said left and right garboard strakes and said side strakes. 
     
     
         7 . The ship structure as claimed in  claim 6 , wherein said drive unit further comprises a first valve connected between said pneumatic motor and said air compressor for the input of the high pressure gas produced by said air compressor into said pneumatic motor subject to the control of said control unit. 
     
     
         8 . The ship structure as claimed in  claim 6 , wherein said drive unit further comprises a second valve connected between said pneumatic motor and said high pressure gas cylinders and controlled by said control unit to let the high pressure gas produced by said air compressor be stored in said high pressure gas cylinders.
