DETAILED DESCRIPTION OF THE INVENTION

(30) The following provides a detailed description on the technical solution of the embodiments of the present invention along with the accompanied drawings of FIG. 1FIG. 29. Clearly, it can be understood that the embodiments described in the following refer to only a portion of the embodiments of the present invention, which shall not be treated as all of the embodiments of the present invention. In view of the embodiments of the present invention, any other embodiments achieved by a person skilled in the art in this field based on the present invention without any effort of inventiveness shall be considered to be part of the scope of the present invention.

(31) As shown in FIG. 1FIG. 29, the present invention provides a grid assembly intelligent photovoltaic power generation system, comprising a supporting unit, a separated composite stand 2, a shaft with square of a shape of cross-section 5 and photovoltaic panels 1. The shaft with square of a shape of cross-section 5 is arranged on the separated composite stand 2 and is capable of rotating on the separated composite stand 2. The separated composite stand 2 is secured on the supporting unit. A plurality of photovoltaic panels 1 are secured onto the shaft with square of a shape of cross-section 5 to form a single-row of photovoltaic panel grid; wherein in a condition that a plurality of the photovoltaic panel grids form a photovoltaic array, a certain distance is formed between each row of the photovoltaic panel grid.

(32) The supporting unit comprises a standing column 3, a main beam with double-slot 4 and a base 8. The top portion of the standing column 3 is connected to the main beam with double-slot 4 and a bottom portion thereof is connected to the base 8.

(33) The shaft with square of a shape of cross-section 5 and the main beam with double-slot 4 are arranged perpendicular to each other and are installed onto the separated composite stand 2 via a self-lubricating composite sleeve with the square shape-to-circle shape portion 9. The bottom portion of the separated composite stand 2 is connected to T-shape bolts installed inside slots 41 at a top portion of the main beam with double-slot 4. The photovoltaic panels 1 are installed onto the shaft with square of a shape of cross-section 5 via a secure beam 10.

(34) The present invention further comprises a transmission shaft 7 and a driving shaft 6. The transmission shaft 7 includes one end connected to the shaft with square of a shape of cross-section 5 and another end connected to the driving shaft 6.

(35) The present invention further comprises an intelligent type control box with a processing unit 14, an angle detector and a driving mechanism; wherein the intelligent type control box with the processing unit 14 is installed at the standing column 3, the angle detector is installed on the photovoltaic panel grid at a lateral side of the intelligent type control box with the processing unit 14, and the driving mechanism is connected to the driving shaft 6.

(36) The main beam with double-slot 4 includes special slots 41 for T-shape bolts formed on top and bottom portions thereof.

(37) A wear-resistant composite spacer 11 is arranged between the separated composite stand 2 and the self-lubricating composite sleeve with the square shape-to-circle shape portion 9.

(38) The standing column installation shaft 81 at a top portion of the base 8 includes two rows of secure holes formed thereon, and each row of the secure holes include three threaded holes arranged at 120 degrees with each other. A protective cover is arranged at a connecting portion between the base 8 and the standing column 3.

(39) The self-lubricating composite sleeve with the square shape-to-circle shape portion 9 includes a square hole formed at middle portion thereof, and a small circular plate 93 and a large circular plate 91 are arranged at two sides thereof respectively. A central circular column 92 is arranged between the large circular plate 91 and small circular plate 93. The axial line of the large circular plate 91 and the axial line of the small circular plate 93 are non-collinear.

(40) The top portion of the separated composite stand 2 includes a sleeve installation portion 21 having a circular hole formed thereon. The lower portion of the sleeve installation portion 21 includes a vertical plate 24, and a side plate 22 is arranged at two sides of the vertical plate 24 and perpendicular to the vertical plate 24. The lower portion of the side plate 22 includes a horizontal plate 23 arranged perpendicular thereto, and the horizontal plate 23 includes secure holes 25 formed thereon.

(41) As shown in FIG. 1, the present invention can be reconfigured to increase and expand the photovoltaic panels according to different conditions. The single-row photovoltaic array can use the driving linkage shaft mechanism to control the movement of the driving shaft 6, and the driving shaft 6 can further drive the transmission shaft 7 to move, followed by using the transmission shaft 7 to push the shaft with square of a shape of cross-section 5 to rotate such that the entire single-row of photovoltaic array is driven to rotate; therefore, it is able to achieve the adjustment of the angle of the photovoltaic panels 1. At different regions, the inclination angle of the photovoltaic panels 1 can be different. In addition, the inclination photovoltaic system can also be used to calculate and control the inclination angle of the photovoltaic panels 1 at each time interval such that the photovoltaic panels 1 being arranged at the most optimal positions at all times can be achieved, and it is of the highest utilization rate of the sunlight. After the entire system is assembled completely, the end portion and the central portion of the system can be further arranged with stabilizing supportive stands 13 respectively in order to ensure that during the process of use, the present invention is more stable and reliable.

(42) In addition, a gap is designed between the rear and front signal-row of the photovoltaic array in order to ensure that when the photovoltaic panels 1 are rotated to the horizontal level, there is still a certain distance between the front and rear photovoltaic panels; therefore, such configuration is able to prevent interference between the front and rear photovoltaic panels during the rotation thereof. Furthermore, with the reasonable design of the gap and the rotation of the photovoltaic panels, the photovoltaic panels 1 can be rotated to control the amount of sunlight exposure for the land or agricultural sheds 12 underneath the photovoltaic panels 1; therefore, the amount of sunlight exposure for the land or agricultural sheds 12 underneath the photovoltaic panels is adjustable, which facilitates the growth of the agricultural crops on land or in the agricultural sheds 12.

(43) As shown in FIG. 4 and FIG. 8, the shaft with square of a shape of cross-section 5 and the main beam with double-slot 4 are arranged perpendicular to each other. The photovoltaic panels 1 are installed onto the shaft with square of a shape of cross-section 5 via the secure beam 10. The shaft with square of a shape of cross-section 5 is installed on the separated composite stand 2 via the self-lubricating composite sleeve with the square shape-to-circle shape portion 9. The bottom portion of the separated composite stand 2 is connected via the T-shape bolt inside the slot 41 installed on the top portion of the main beam with double-slot 4, and the main beam with double-slot 4 is further connected to the standing column 3. The bottom of the standing column 3 is connected to the base 8 via the T-shape bolts. One end of the transmission shaft 7 is connected to the shaft with square of a shape of cross-section 5 and another end thereof is connected to the driving shaft 6. Since the main beam with double-slot 4 and the shaft with square of a shape of cross-section 5 are perpendicular to each other and are connected via the separated composite stand 2, the present invention can be form of a web structure. Consequently, when a certain number of single-row photovoltaic arrays are installed on the main beam with double-slot 4, the entire structure can be of greater stability and greater performance in terms of wind resistance and tipping-over resistance.
