When the driving member of the present invention is used, the driving shaft 400 transmits the torque to the driving dial 301 of the sheave mechanism 300, and the driving dial 301 is matched with the driven sheave 302 to drive the driven sheave to rotate, so as to drive the supporting beam 100 to rotate relative to the upright post 200 under the action of the driving mechanism 500. The driving member of the present invention has a self-locking function of the sheave mechanism 300, so that the support beam 100 is not easily shaken in bad weather, thereby prolonging the service life of the photovoltaic module 600.

In order to reduce the friction during the rotation of the support beam 100 with respect to the column 200, a bearing is provided between the support beam 100 and the column 200. The inner race of the bearing is fixed to the support beam 100 and the outer race of the bearing is fixed to the column 200. Or the inner ring of the bearing is fixed to the column 200 and the outer ring of the bearing is fixed to the support beam 100. Due to the characteristics of the bearing, the friction force of the support beam 100 relative to the upright post 200 in the rotating process is reduced, and the stability of the support beam 100 in the rotating process is improved.

The transmission shaft 400 and the driving dial 301 can transmit through splines, flat keys, threads and the like, and a universal joint coupler is arranged between the transmission shaft 400 and the driving dial 301 in the embodiment of the invention and transmits torque to the driving dial 301 through the universal joint coupler.

When the support beam 100 is in a horizontal state, please refer to fig. 3, when the support beam 100 needs to be adjusted in a first direction, the transmission shaft 400 is rotated, and under the driving action of the transmission shaft 400, the driving dial 301, the driven sheave 302 and the transmission mechanism 500 all rotate and drive the support beam 100 to deflect in the first direction, and due to the limiting action of the sheave mechanism 300, the support beam 100 can be locked at the position, please refer to fig. 4; when the support beam 100 needs to be adjusted in the second direction, the transmission shaft 400 is rotated in a reverse direction, and under the driving action of the transmission shaft 400, the driving dial 301, the driven sheave 302 and the transmission mechanism 500 are all rotated, and the support beam 100 is driven to deflect in the second direction, and due to the limiting action of the sheave mechanism 300, the support beam 100 can be locked at the position, please refer to fig. 5.

In one embodiment of the present invention, the Geneva gear 300 is mounted on the mast 200, or the Geneva gear 300 is mounted directly on the support beam 100. Take the example of the geneva gear 300 being disposed on the shaft 200: a driving dial 301 and a driven sheave 302 of the sheave mechanism 300 are both rotatably arranged on the upright post 200; or the geneva mechanism 300 is arranged on the upright post 200 through a fixing frame 303, the driving dial 301 and the driven geneva 302 matched with the driving dial 301 are rotatably arranged in the fixing frame 303, and the fixing frame 303 is fixed on the upright post 200. The fixing frame 303 is welded to the column 200 or detachably mounted to the column 200. When the fixing frame 303 is installed on the column 200, a rotating shaft for fixing the driving dial 301 and the driven sheave 302 may be fixed on the column 200 as a fixing member.

It should be noted that, in the embodiment of the present invention, the number of the transmission grooves on the driven sheave 302 is six, but the number of the transmission grooves in the embodiment of the present invention is not limited to six, and may be seven, eight, nine, and so on, and the larger the number of the transmission grooves, the more precise the angle adjustment of the support beam 100 during the transmission of the sheave mechanism 300. When the number of the transmission grooves is multiple, the transmission grooves are symmetrically arranged on the driven grooved wheel 302.

The transmission mechanism 500 functions to convert the rotational motion of the driven sheave 302 into the rotational motion of the support beam 100. In one embodiment of the invention the transmission mechanism is a linkage mechanism, a gear mechanism or the like.

When the transmission mechanism 500 is a link mechanism, the transmission mechanism 500 includes a link rod, two ends of the link rod are hinged to the driven sheave 302 and the support beam 100, wherein the link rod is directly hinged to the driven sheave 302, and can also be hinged to the driven sheave 302 through other components, specifically, a transmission rod 304 is relatively fixedly disposed on the driven sheave 302, the transmission rod 304 can synchronously rotate relative to the driven sheave 302, the transmission rod 304 is fixed on the driven sheave 302, and the link rod is hinged to the transmission rod 304. The driven sheave 302 can rotate under the action of the driving dial 301, and the driving rod 304 is fixed relative to the driven sheave 302, so that the driving rod 304 rotates relative to the driven sheave 302, the rotating motion of the connecting rod can drive the connecting rod to move, and further, the connecting rod can drive the supporting beam 100 to rotate, thereby achieving the purpose of adjusting the angle of the supporting beam 100.

In order to reduce the friction between the connecting rod and the support beam 100, a bearing may be provided between the connecting rod and the support beam 100.

Further, in order to improve the stability in the angle adjustment process, the number of the connecting rods in the transmission mechanism is multiple, and the multiple connecting rods, the transmission rod 304 and the support beam 100 form a parallel four-bar linkage. Preferably, the number of the connecting rods is two, i.e. a first connecting rod 501 and a second connecting rod 502, respectively, the first connecting rod 501 and the second connecting rod 502 are hinged between the driven sheave 302 and the support beam 100, respectively, and the first connecting rod 501, the second connecting rod 502, the driven sheave 302 and the support beam 100 form a parallel four-bar linkage.

When the transmission mechanism is hinged to the driven sheave 302 through the transmission rod 304, the first link 501 and the second link 502 are respectively located at both ends of the transmission rod 304. The first link 501, the second link 502, the transmission rod 304 and the support beam 100 form a parallel four-bar linkage, and due to the characteristics of the parallel four-bar linkage, the geneva gear 300 can stably drive the support beam 100 to perform angle adjustment.

When the transmission mechanism 500 is a gear mechanism, the transmission mechanism 500 includes a driving gear 503 coaxially and fixedly connected to the driven sheave 302, and an arc gear 504 engaged with the driving gear 503, wherein the arc gear 504 is fixedly connected with respect to the support beam 100, and a center of the arc gear 504 is on a rotation axis of the support beam 100.

The driven sheave 302 drives the driving gear 503 to rotate in the process of rotating under the action of the driving dial 301, the driving gear 503 can drive the arc gear 504 to rotate due to the engagement of the arc gear 504 and the driving gear 503, and the arc gear 504 can drive the support beam 100 to rotate relative to the upright post 200 due to the fact that the circle center of the arc gear 504 is on the rotation axis of the support beam 100. The arc gear 504 may be an outer ring gear or an inner ring gear. Referring to fig. 6 and 7, the arc gear 504 in fig. 6 is an outer ring gear, and the arc gear 504 in fig. 7 is an inner ring gear.

In order to enhance the connection strength of the arc gear 504 to the support beam 100, the arc gear 504 is fixed to the support beam 100 by a bent arm beam. Further, the bent arm beam is fixed to the main body of the support beam 100 by an F-shaped connection beam 505 for easy installation. Or when the support beam 100 is coupled to the column 200 by a rotating shaft, that is, the support beam 100 is fixed to the rotating shaft, the F-shaped connection beam 505 is fixed to the rotating shaft; or when the support beam 100 is coupled to the column 200 through the rotation hole, the support beam 100 is provided with a rotation frame 101, the rotation frame 101 has a rotation hole, the rotation frame 101 is fixed to the support beam 100, and the F-shaped connection beam 505 is fixed to the rotation frame 101. Furthermore, in order to further improve the connection strength between the support beam 100 and the rotating frame 101 or the rotating shaft, the support beam 100 and the rotating shaft or the rotating frame 101 are further provided with a reinforcing rod 102, one end of the reinforcing rod 102 is fixed on the support beam 100, and the other end of the reinforcing rod 102 is fixed on the rotating shaft or the rotating frame 101.

Because above-mentioned drive component has above beneficial effect, including above-mentioned drive component's photovoltaic support also has corresponding effect, and the no longer repeated description here.

In one embodiment of the present invention, the number of support beams 100 is plural, the number of columns 200 is plural, and the number of driving members is plural, each driving member being provided on a corresponding column 200, the driving shafts 400 of the driving members located in the same row being coaxially arranged. The object of driving the support beam 100 at multiple points can be achieved by providing a plurality of driving members.

In one embodiment of the present invention, the driving members located in the same row share one driving shaft 400. The transmission shaft 400 can simultaneously drive the plurality of sheave mechanisms 300 on the transmission shaft 400 to simultaneously operate in the rotating process, and due to the structural characteristics of the sheave mechanisms 300, even if the moment of the photovoltaic module 600 on the sheave mechanisms 300 on the same row of the upright posts 200 is different, the angles of the driven sheaves 302 corresponding to the driving mechanisms are the same due to the synchronous angles of the sheave mechanisms 300 in the rotating process, and the probability of the twisting of the supporting beams 100 arranged in the same row is very low, so that the service life of the photovoltaic module 600 can be further prolonged.

As described above, the transmission shaft 400 in the embodiment of the present invention may be driven by a human power or a motor, and specifically, the transmission shaft 400 is provided with a manual rocker mechanism or a driving motor.
