Abstract

Supporting structure (10) for a parabolic-linear solar plant (14) of the concentrating type, suitable to supporting mirrors (12) with a curved surface, which intercept the sun's rays and directing them towards a receiver member to produce energy, such as a receiver tube (16) in which a heat exchange fluid flows and/or concentration-type pho tovoltaic cells, the receiver member is disposed along a first axis (X) of substantial alignment of the focuses of said mirrors (12). The sup porting structure (10) comprises a supporting shaft (18) that develops parallel to a second rotation axis (Y) parallel to said first axis (X), sup porting centrings (22) of mirrors (12) are mounted along said support ing shaft (18), placed transversal from opposite sides with respect to said supporting shaft (18) in a manner coordinated with the position of said mirrors (12). Each of the supporting centrings (22) has pivot ing ends (26) coupled with the supporting shaft (18). The supporting structure (10) further comprises first positioning blocks (34) disposed along the supporting shaft (18) in a manner coordinated to the dis position of the centrings (22), which have, on opposite sides with re spect to the supporting shaft (18), first supporting faces (36) turning, during the use, towards the centrings (22). Said pivoting ends (26) of the centrings (22) carry second positioning blocks (38) having second supporting faces (40) turning, during the use, towards the support ing shaft (18) and apt to cooperate in beating with the first support ing faces (36). The first supporting faces (36) and second supporting faces (40) have surfaces processed together to define reciprocally co ordinated shapes, so as to ensure the precise positioning of centrings (22) with respect to the supporting shaft (18), so that the mirrors (12) supported by centrings (22) are correctly oriented with their focuses properly aligned along the first axis (X).

Abstract

Movement mechanism (10) for moving an interception element (11) of a solar plant. The mechanism (10) is mounted on a support frame (12) and is constrained to the interception element (11) to allow the movement thereof with respect to the support frame (12). The mechanism (10) comprises a drive member (17) which generates a motion, and a transmission kinematism (19) which transmits the motion to a rotation shaft (16) constrained to the interception element (11). The transmission kinematism (19) comprises a first mechanical member (22) with gears mounted rotatable on a first support (20) and mechanically connected to the drive member (17), and a second mechanical member (23) with gears engaged on the first mechanical member (22), mounted on a second support (21), and keyed to the rotation shaft (16). The first and the second support (20, 21) are pivoted to each other with respect to a determinate pivoting axis (X), in order to rotate around the pivoting axis (X), so as to bring together/distance the first and the second mechanical member (22, 23).

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 (12) and to be constrained to the interception element (11), in order to allow the movement thereof with respect to the support frame (12), and comprises a fixed body (20) suitable to be assembled on the support frame (12), a rotating body (21) assembled rotatable inside the fixed body (20) around an axis of rotation (X) and suitable to be constrained to the interception element (11), and a plurality of rolling members (23) disposed rotating between relative sliding tracks (25, 27) made both on the fixed body (20) and also on the rotating body (21). The mechanism movement comprises at least a compensation seating (30) made on the fixed body (20) and/or on the rotating body (21) which extends with respect to said sliding tracks (25, 27) in a direction substantially parallel to the axis of rotation (X), to define a controlled play of axial displacement controlled by the rolling members (23).
