Among the present invention, can the moment of torsion transmission plate be set to four, per two is one group, and one group is connected with first hydraulic cylinder, and another group is connected with second hydraulic cylinder, can reduce the axial length of drive unit like this, improves the efficient of concentrating collector.
Apparatus of the present invention, when the moment of torsion transmission plate was in straight down the position, two hydraulic cylinders laid respectively at the both sides that rotation axis axial line and moment of torsion transmitter shaft axial line are confirmed the plane.
Drive unit of the present invention is connected with concentrating collector through driving web joint.
Beneficial effect:Apparatus of the present invention are compared with prior art, have the following advantages:
1. this device has adopted vertical bar shape moment of torsion transmission plate, steel pipe, steel plate to transmit moment of torsion, and it is simple in structure, is easy to processing.
2. this device has adopted the moment of torsion transmitter shaft to transmit moment of torsion, because the driving force of hydraulic cylinder is bigger, and moment is to drive the distance of the axial line of hydraulic cylinder to rotational axis line; This distance is bigger, thus can transfer larger torque, and the space structure that constitutes of rotation axis, moment of torsion transmission plate and moment of torsion transmitter shaft; Can transfer larger torque to driving on the web joint; Carrying capacity is big so this drive unit can carry, and wind resistance is good, and this drive unit has safe and reliable characteristics.
3. the upper end of hydraulic cylinder connects through a pin and moment of torsion transmission plate lower ends, can reduce the axial length of drive unit like this; When one timing of light and heat collection partial-length; Be that effective thermal-arrest length is equal to, and the length of thermal-collecting tube equals the axial length that the axial length of condenser adds drive unit, reduce the axial length of drive unit; Promptly reduce the total length of thermal-collecting tube; Promptly increase the ratio of light and heat collection part on total length, also reduced the thermal loss of thermal-collecting tube, can improve the overall thermal utilization ratio of concentrating collector.
