In described solar energy tracking and driving system, described rocking bar is vertical with described rotating shaft.
In described solar energy tracking and driving system, the sensitive surface of the vertical or parallel described cumulative device of described rocking bar.
In described solar energy tracking and driving system, described slide block driving mechanism comprises and the coaxial screw mandrel that is connected of described reducing motor, be provided with the screw mandrel cover of the internal thread that matches with described wire rod thread, described screw mandrel cover relatively rotates connection with described slide block in the plane of parallel rocking bar.
In described solar energy tracking and driving system, described slide block driving mechanism also comprises the bearing of parallel described rocking bar, and the inner ring of described bearing is fixed on described screw mandrel and puts, and the outer ring of described bearing is fixed on the described slide block; Perhaps described screw mandrel cover is fixed on the outer ring of bearing of parallel described rocking bar, and described slide block is fixed in the inner ring of described bearing.
At described solar energy tracking and driving system, the vertical described rotating shaft of described screw mandrel.
Implement solar energy tracking and driving system of the present invention, because the slide block endplay device changes the circumferential shearing force that the rotating shaft rotation produces into translation required thrust, can change the size of required thrust by the relative position of regulating rocking bar and slide block, thereby avoid producing the circumferential shearing force between worm and gear in the prior art or the gear pair, simple in structure, use common material and technology to realize, and do not have the failure conditions of broken teeth, implementation cost is lower, and performance is more reliable.On the other hand, relatively rotate the screw mandrel cover that is connected with slide block by being provided with, make slide block along and the coaxial screw mandrel rectilinear motion that is connected of reducing motor, the torque conversion that reducing motor is exported is the required thrust of slide block rectilinear motion.The special profile of tooth (rectangle or trapezoidal) of screw mandrel makes this structure stronger than the ability that worm and gear or gear pair bear shearing force.The present invention is by providing a kind of novel structure that is different from the past, solved the need servomechanism installation cost that exists in the prior art high and problem that lost efficacy easily; Compared with prior art, do not need special material and technology during manufacturing, practical, cost is lower, more reliable performance.
