Movement Mechanism and Solar Plant Using Said Mechanism

Abstract

Movement mechanism for at least an interception element assembled mobile on a support frame to assume an optimized interception condition. The movement mechanism is suitable to be assembled on the support frame and to be constrained to the interception element, in order to allow the movement thereof with respect to the support frame, and comprises a fixed body suitable to be assembled on the support frame, a rotating body assembled rotatable inside the fixed body around an axis of rotation and suitable to be constrained to the interception element, and a plurality of rolling members disposed rotating between relative sliding tracks made both on the fixed body and also on the rotating body. The mechanism movement comprises at least a compensation seating made on the fixed body and/or on the rotating body which extends with respect to said sliding tracks in a direction substantially parallel to the axis of rotation, to define a controlled play of axial displacement controlled by the rolling members.

1 .

         2 . The movement mechanism as in  claim 1 , wherein the compensation seating is made on the ring-nut at least on one side of the relative sliding track. 
     
     
         3 . The movement mechanism as in  claim 1 , wherein it comprises elastic contrast means provided inside the compensation seating, to at least partly absorb the movement of the rolling members. 
     
     
         4 . The movement mechanism as in  claim 1 , wherein said rolling members comprise at least an annular crown of rolling rollers. 
     
     
         5 . The movement mechanism as in  claim 1 , wherein said rolling members comprise at least an annular crown of rolling balls. 
     
     
         6 . A solar plant comprising at least an interception element, a support frame on which said interception element is assembled mobile to assume an optimized interception condition, and at least a movement mechanism assembled on the support frame, and constrained to said interception element, in order to allow the movement thereof with respect to the support frame, said movement mechanism comprising a fixed body assembled on said support frame, a rotating body assembled rotatable inside the fixed body around an axis of rotation and constrained to the interception element, and a plurality of rolling members disposed rotating between relative sliding tracks made both on the fixed body and also on the rotating body, wherein the movement mechanism comprises at least a compensation seating made on the fixed body and/or on the rotating body and extending with respect to said sliding tracks in a direction substantially parallel to the axis of rotation, to define a controlled play of axial displacement of said rolling members, wherein said fixed body comprises at least a ring-nut attached radially to the fixed body and on which a relative sliding track is made, the compensation seating is made directly on the fixed body and the ring-nut is disposed axially mobile inside said compensation seating. 
     
     
         7 . The solar plant as in  claim 6 , wherein the compensation seating is made on the ring-nut at least on one side of the relative sliding track. 
     
     
         8 . The solar plant as in  claim 6 , wherein for each movement mechanism it comprises one or more attachment elements able to allow the direct or indirect attachment of the interception element to the fixed body. 
     
     
         9 . The solar plant as in  claim 6 , wherein it also comprises at least a drive member kinematically connected to the movement mechanism, to command the rotation of the rotating body. 
     
     
         10 . The solar plant as in  claim 6 , wherein it comprises at least a position transducer member operatively connected to the rotating body of the movement mechanism, to control the parameters of rotation thereof.
