Turbine structure and gate structure having flexible joint and inside stuffing for tidal power plant

Abstract

A turbine structure and a gate structure for tidal power plants of the present invention features that middle walls which can be installed as two units of one block are installed with an inside stuffing and a flexible joint so as to absorb and reduce the internal and external effects of the buoyancy and mechanical vibration of the turbine structures and the gate structures on the tidal power plants, save construction costs by shortened construction period and reduced concrete placing quantity, and prevent the cracks of concrete and the generation of hydration heat. The turbine structure having the flexible joint and the inside stuffing for tidal power plants comprises a base which bottom part is on the submarine rock so that a turbine structure between lake and sea which is connected with a gate structure by the medium of a connection structure can be installed as two units of one block; vertical middle walls which are formed on the base, the top of which is closed by a concrete structure wherein a draft tube and a discharge tube by which seawater can move inside; turbine generators which are arranged between the middle walls through the draft tubes; an inside stuffing space which is formed in the middle walls on one side installed in a predetermined distance on the base of the gate structure and filled with seawater; and a flexible joint of connecting the middle walls on the other side.

1 . A turbine structure having a flexible joint and an inside stuffing for tidal power plants, comprising:
 a base whose bottom part is on the submarine rock so that a turbine structure between lake and sea, which is connected with a gate structure by the medium of a connection structure, can be installed as two units of one block;   vertical middle walls which are formed on the base, the top of which is closed by a concrete structure wherein a draft tube and a discharge tube by which seawater can move inside;   turbine generators which are arranged between the middle walls through the draft tubes;   an inside stuffing space which is formed in the middle walls on one side installed in a predetermined distance on the base of the gate structure and filled with seawater; and   a flexible joint of connecting the middle walls on the other aide.   
   
   
       2 . The turbine structure of  claim 1 , wherein the material of the flexible joint is either cork or expandable polystyrene. 
   
   
       3 . The turbine structure of  claim 1 , wherein pipe meters for water level observation may be installed for seawater level management in the inside stuffing space filled with seawater in the middle walls 
   
   
       4 . A gate structure having flexible joint and inside stuffing for tidal power plant, comprising:
 a base which bottom part is on the submarine rock so that a gate structure between lake and sea which is connected with a turbine structure by the medium of a connection structure can be installed as two units of one block;   vertical middle walls which are formed on the base, the top of which is closed by a concrete structure wherein a waterway by which seawater can move inside;   water gates which are arranged on one side of the waterway installed between the middle walls;   an inside stuffing space which is formed in the middle walls on one side installed in a predetermined distance on the base of the gate structure and filled with seawater; and   a flexible joint of connecting the middle walls on the other side.   
   
   
       5 . The gate structure of  claim 4 , wherein the material of the flexible joint is either cork or expandable polystyrene. 
   
   
       6 . The gate structure of  claim 5 , wherein pipe meters for water level observation may be installed for seawater level management in the inside stuffing space filled with seawater in the middle walls
