Swivel-type floating structure using buoyancy

Abstract

A swivel-type floating structure using buoyancy is provided. The structure includes a buoyant plate configured to have a buoyancy to float on a surface of water; one or more first link bars configured to have one end rotatably assembled to at least one first plate bracket fixed to both sides of the buoyant plate by means of a pin, and the other end rotatably assembled to a first ground bracket fixed to a ground adjacent to the buoyant plate by means of another pin; and one or more second link bars configured to have one end rotatably assembled to at least one second plate bracket fixed to a first end of the buoyant plate by means of a pin, and the other end rotatably assembled to a second ground bracket fixed to a ground adjacent to the first ground bracket by means of another pin.

What is claimed is: 
     
         1 . A swivel-type floating structure using buoyancy, comprising:
 a buoyant plate configured to have a buoyancy to float on a surface of water;   at least one first link bar configured to have a first end rotatably assembled to at least one first plate bracket fixed to both sides of the buoyant plate by means of a first pin, and a second end rotatably assembled to a first ground bracket fixed to a ground adjacent to the buoyant plate by means of a second pin; and   at least one second link bar configured to have a first end rotatably assembled to at least one second plate bracket fixed to a first end of the buoyant plate by means of a third pin, and a second end rotatably assembled to a second ground bracket fixed to the ground adjacent to the first ground bracket by means of a fourth pin.   
     
     
         2 . The swivel-type floating structure according to  claim 1 , wherein the at least one first link bar comprises:
 a pair of first plate brackets provided on both ends of the first end of the buoyant plate, and   a pair of link bars of a predetermined length disposed in pairs with each end thereof rotatably connected; and   the at least one second link bar comprises:   a second plate bracket provided on a second end of the buoyant plate and   one link bar of a predetermined length disposed between a pair of first link bars with one end thereof rotatably connected.   
     
     
         3 . The swivel-type floating structure according to  claim 1 , wherein the at least one first link bar comprises:
 a pair of first plate brackets provided on both ends of the first end of the buoyant plate, and   a pair of link bars of a predetermined length disposed in pairs with each end thereof rotatably connected; and   the at least one second link bar comprises:   a pair of second plate brackets provided on both sides of a second end of the buoyant plate and   a pair of link bars disposed in parallel with the at least one first link bar with each end thereof rotatably connected.   
     
     
         4 . The swivel-type floating structure according to  claim 1 , wherein the at least one first link bar and the at least one second link bar comprise:
 an upper link pipe having an upper end rotatably assembled to the first and second plate brackets fixed to the buoyant plate and having an elongated guide hole formed at a lower portion; and   a lower link bar having a lower end rotatably assembled to the first and second ground brackets fixed to the ground, an upper end inserted into an opened lower end of the upper link pipe to be reciprocated, and a latching guide bar engaged with the elongated guide hole.   
     
     
         5 . The swivel-type floating structure according to  claim 1 , wherein the at least one first link bar and the at least one second link bar are disposed parallel to each other.
