The periphery of the interface between the first bearing 242 and the second bearing 243 is covered with a sleeve 25, one end of the sleeve 25 abuts against the inner side wall of the first guide rod 311, and the other end abuts against the inner side wall of the second guide rod 312. With such an arrangement, the first bearing 242 and the second bearing 243 are connected, and the interval between the first guide rod 311 and the second guide rod 312 is not easy to deform under the action of external force, so that the stability of the transmission device is better, and the service life is longer.
As shown in fig. 1, the transmission device further includes a housing 4 for accommodating the telescopic mechanism 1, the transmission mechanism 2 and the guide mechanism 3, and the housing 4 is fixedly connected to the guide mechanism 3. The motor 21 is mounted on a side wall outside the housing 4. So set up, play waterproof dirt-proof effect to telescopic machanism 1, drive mechanism 2 and guiding mechanism 3, can prolong transmission's life.
The present invention also discloses a photovoltaic rack system, please refer to fig. 13 to 14, the photovoltaic rack system includes: a plurality of stands 5 interval arrangement, the rotatable setting of a girder 6 is in the top of a plurality of stands 5, be fixed with a plurality of photovoltaic boards on the girder 6, wherein, be fixed with regulating arm 7 on the girder 6, with regulating arm 7 is corresponding be equipped with mount pad 51 on the stand 5, transmission one end articulate in regulating arm 7 and the other end articulate in mount pad 51, thereby through adjusting transmission's flexible drive girder 6 rotation is adjusted the inclination of photovoltaic board. In particular, the upper telescopic rod 131 of the transmission device is hinged to the adjusting arm 7 and the lower telescopic rod 132 is hinged to the mounting seat 51. The photovoltaic support system is provided with a plurality of transmission devices and further comprises linkage rods 8, the transmission devices are connected with the linkage rods 8 respectively to enable the transmission devices to move synchronously, so that the photovoltaic support system can drive the main beam 6 synchronously at multiple points, specifically, the linkage rods 8 are connected between the adjacent lead screws 22 respectively to drive the main beam 6 to rotate synchronously by synchronously driving the transmission devices, and the inclination angle of the photovoltaic panel is adjusted.
Please refer to fig. 15 and 16, the transmission device of the present invention can also be used for linkage between two photovoltaic support systems arranged side by side, wherein, push arms 61 are respectively fixed on the positions of the main beams 6 corresponding to the two photovoltaic support systems, the two push arms 61 are respectively hinged at two ends of a connecting rod 10, a support 9 is further fixed on the base surface between the two photovoltaic support systems, the lower telescopic rod 132 of the transmission device is connected to the support 9, and the upper telescopic rod 131 of the transmission device is hinged at one end of the connecting rod 10. The connecting rod 10 can be driven to reciprocate along the B-B direction by driving the transmission device, so that the main beams of the two photovoltaic support systems are driven to synchronously rotate. Wherein, the position of the support can also be arranged on one photovoltaic bracket system and is not limited to the position shown in fig. 15.
In summary, the transmission device of the present invention connects the transmission mechanism 2 with the telescoping mechanism 1, and the guiding mechanism 3 is used to limit the telescoping mechanism 1, the motor 21 drives the screw rod 22 to rotate, so that the transmission nut 23 on the screw rod 22 drives the left and right ends of the telescoping mechanism 1 fixed thereto to move left and right, and the upper and lower ends of the telescoping mechanism 1 drive the upper telescoping rod 131 and the lower telescoping rod 132 to move up and down. The transmission device is applied to the photovoltaic support system, and the main beam 6 is driven to rotate through the extension of the transmission device so as to adjust the inclination angle of the photovoltaic panel.
The above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, and the understanding of the present specification should be based on the technical personnel in the technical field, such as the directional descriptions of "front", "back", "left", "right", "upper", "lower", etc., although the present specification has described the present invention in detail with reference to the above embodiments, the ordinary skilled in the art should understand that the technical personnel in the technical field can still make modifications or equivalent substitutions on the present invention, and all the technical solutions and modifications thereof without departing from the spirit and scope of the present invention should be covered in the claims of the present invention.
