Wave powered cyclic anchoring itinerant ship propulsion system

Abstract

Method of cyclic anchoring itinerant (CAI) propulsion uses a phenomenon of anchored float horizontal motion as wave rises. The method repeats a cycle: Detaching the anchor from an immobile medium as a wave begins descent; Accelerating it in new position as the wave descends; Reattaching it to said medium as a wave rises. The medium can be railway or water. Respectively a trolley or a glider works as the anchor. To drag as anchor the glider orients perpendicular to the link. Improvements: adding an auxiliary propeller accelerating the glider, connecting bow and aft gliders with a single boom, making it telescopic, adding a small submarine hull for permanent observation water space, scientific researches, entertainment. The method allows to reequip watercrafts to all-weather, ocean going watercrafts with an unlimited range of operation. These solutions can be widely used in marine rescue remedies. Experimental models of CAI propulsion system show remarkable results.

1 . Method of ship propulsion based on rise of additional buoyancy force in reply to a pull force of a tilted anchor rope detaining free ship ascent by a wave; a vector sum of these forces is a thrust, renewed by the next wave if during its descent the anchor device unhooks, itinerates forward and hooks in the immobile medium.  
     
     
         2 . Method of ship propulsion, according to  claim 1 , where a railway, mounted on bottom piers, and a trolley, traveling on this railway, are used in the capacity of the medium and the itinerant anchor device, respectively.  
     
     
         3 . Method of ship propulsion, according to the  claim 1 , where surrounding water, and a underwater glider, dangled with two ropes, are used in the capacity of the medium and the itinerant anchor device respectively.  
     
     
         4 . An anchor-trolley set on underwater horizontal railway and itinerating along it for temporary fixing to it as the anchor that needed to generate thrust force when the tilted anchor rope is stretched from a floating mean; so the anchor-trolley is the basic anchoring device for the ship propulsion according to  claim 2 .  
     
     
         5 . An anchor-glider dangling from floating mean with pair of ropes and sliding forward for temporary stops to function as an anchor providing thrust generating, when the tilted anchor rope are stretched from a ship subjected the propulsion according to  claim 3 .  
     
     
         6 . Method improving the anchoring capability of the underwater glider based on imparting to it a designed alterability stabilizing its operation for various values of the pull forces.  
     
     
         7 . Method accelerating the glider itineration based on using an auxiliary propeller as a wave descents; this method improves propulsion quality at the expense of the best position glider can occupy as a wave starts its ascent.  
     
     
         8 . On-board crane manipulating with the anchor-glider and able: 
 a. to lift it for maintenance or preservation against a harmful environment,    b. to turn it left or right to steer the ship,    c. to move it up and down by on-board power, activating the propulsion in calm seas or assisting the propulsion according to  claim 1 ,    d. to control the anchor rope length adapting it to wave parameters.    
     
     
         9 . Method of ship propulsion according to  claim 1 , where two cranes, according to  claim 6 , used to control, simultaneously, two anchor-gliders hanged each with two dangling ropes to increase capability and uniformity of the ship propulsion system as a whole.  
     
     
         10 . Method of ship propulsion, according to the  claim 7 , where two anchor-gliders, hanged each with a single dangling rope and the gliders mutually connected by a common boom-sinker.  
     
     
         11 . Method of ship propulsion, according to  claim 8 , where the boom-sinker is made telescopic, allowing each glider to operate independently that so that propulsion power and quality increases.  
     
     
         12 . A ship propulsion system with the telescopic boom-sinker, as stated by  claim 9 , united with a submarine module to promote underwater observations, scientific research, rescue operations, etc.
