Rotary decoupling biaxial solar condenser parallel tracking mechanism

The invention relates to a rotary decoupling biaxial solar condenser parallel tracking mechanism and belongs to the field of machine manufacturing. The rotary decoupling biaxial solar condenser parallel tracking mechanism comprises a fixed platform, a movable platform, a first support chain and a second support chain, wherein the movable platform is used for mounting a solar condenser. The fixed platform comprises a base, a limit support chain with the top end provided with a Hooke hinge a, and two stand columns or hinges with movable pairs or rotary pairs; the movable platform is connected to the fixed platform through the limit support chain and further connected with the fixed platform through the first support chain and the second support chain to form a parallel mechanism; the movable platform can rotate around the outer circle and the inner circle of the Hooke hinge wound on the limit support chain, namely, obtains two degrees of freedom, and meanwhile, the two rotation motions of the movable platform are decoupled. The rotary decoupling biaxial solar condenser parallel tracking mechanism has the advantages of being high in rigidity and dynamic performance, low in energy consumption and the like.
