The utility model content

Technical problem to be solved in the utility model provides a kind of solar energy tracking rotation platform driving mechanism, adopts this driving mechanism, makes rotation platform follow the tracks of the precision of the sun with stable higher.

For solving the problems of the technologies described above, the utility model provides a kind of solar energy tracking rotation platform driving mechanism, its circular rotation platform comprises inside and outside several concentric circuit orbits, be located between two adjacent tracks and some first tie-beams of space, two orthogonal second tie-beams, the intersection point of two second tie-beams and the center of circle of described track coincide, each track cross level is placed on some support wheels, each support wheel is located on the supporting seat, the some support wheels and the rounded layout of respective support seat of each track below, rotation platform links to each other with bearing on being located at centre mount by the intersection area of two second tie-beams, the radius of setting outermost that circuit orbit is d, uniform some cylindrical pin on the circumferential outer rim of radius greater than arbitrary track of 0.3d, driven wheel engagement on the output shaft of cylindrical pin and pin tooth motor is so that rotation platform links to each other with pin tooth motor.

For can concise description for the purpose of the problem, below solar energy tracking rotation platform driving mechanism described in the utility model be all abbreviated as this driving mechanism.

After adopting above technical scheme, the activation point of pin tooth motor meets the following conditions: apart from the distance in the track center of circle greater than 0.3d, d is the radius of outermost that circuit orbit, like this, the type of drive of this driving mechanism is: pin tooth motor is uniform some cylindrical pin engaged transmission on the circumferential outer rim greater than arbitrary track of 0.3d by driven wheel and radius, the driven rotary platform rotates, making rotation platform carry out the azimuth to the sun follows the tracks of, as seen, adopt motor and by belt or compare with the type of drive of transmission synchronously with existing, the useful life of driven wheel is longer, driven wheel because of season difference variation little to the influence of its telescopic level, like this, precision and stability that rotation platform is followed the tracks of the sun have just been guaranteed, can satisfy the light gathering photovoltaic power generating system of high tracking accuracy or the demand of concentration photo-thermal system, reduce driven wheel and stirred the moment of torsion of cylindrical pin, adopt the lower pin tooth motor of power can overcome the driving torque of rotation platform, therefore, adopt this driving mechanism, make rotation platform follow the tracks of the precision of the sun with stable higher.

As optimization of the present utility model, described pin tooth motor is arranged on the motor cabinet, pin tooth motor is provided with counter, the output shaft of the contact of counter and pin tooth motor is perpendicular, also be provided with the counting gear that is in the driven wheel below on the output shaft of pin tooth motor, counting gear contacts with the contact of counter.

Pin tooth motor, counter all links to each other with the control circuit of peripheral hardware, the driving frequency of pin tooth motor is by the software set that presets in the control circuit, when pin tooth motor is received the driving signal operation that control circuit transmits, the driven wheel rotation, stir cylindrical pin by it, the driven rotary platform rotates, meanwhile, stir counter by counting gear, counter is counted the cylindrical pin of having stirred according to the programming software that control circuit presets, and whenever stirs once, it is identical that the anglec of rotation of rotation platform keeps, like this, can more accurately control, follow the tracks of the precision and the stability of the sun with further raising rotation platform the rotation of rotation platform.
