[0018] The present invention provides a photovoltaic support system and an installation method, such as Figures 1 to 25 As shown, the photovoltaic support system includes a roof frame 1, a support frame 3 and a waterproof frame 2. The support frame 3 is supported between the roof frame 1 and the ground, and the waterproof frame 2 is erected on the roof frame 1 for erecting photovoltaic components 6.

[0019] The following is an introduction to the installation method of the photovoltaic support system in combination with the various accessories in the photovoltaic support system: Set up the support skeleton: like Figure 1 As shown, the support frame 3 is composed of a plurality of columns 31 arranged at intervals. A required number of columns 31 are prepared first, and the lower ends of the columns 31 are fixed to the ground or a designated platform according to a preset laying spacing.

[0020] like Fig. 22 and Fig.23 As shown, the photovoltaic support system of the present invention also includes a base 14, which includes a bottom plate 141 and four side plates 142 vertically arranged on the bottom plate 141. The side plates 142 enclose a cubic connecting column for the column 31 to be plugged in, and a connecting hole 143 is opened on the wall of the side plate 142. In addition, in order to enhance the stability of the structure, a reinforcing plate 144 is provided between the outer side of the side plate 142 and the bottom plate 141 to support the two obliquely. The highest point of the reinforcing plate 144 is located below the connecting hole 143 and does not block the connecting hole 143. During assembly, the lower end of the column 31 is inserted into the connecting column of the base 14, and the fastener 19 is locked with the connecting hole 143 to fix the column 31 to the base 14.

[0021] This solution also adds a movable end cover 145, and a through hole 146 is opened in the middle of the end cover 145 for the column 31 to pass through. After the position of the column 31 is determined and fixed, the end cover 145 is put on the column 31, and the end cover 145 can slide up and down along the column 31, slide down to cover the base 14, making the power station more beautiful, or slide up to reveal the base 14.

[0022] like Fig.18 , 19As shown, a guardrail 15 is also provided between the columns 31 as a reinforcement accessory, which is assembled through a corner clamp assembly 17 or a straight clamp assembly 16 in conjunction with a fastener 19 .

[0023] like Fig.17 As shown, a mounting groove 311 is provided at the upper end of the column 31 , and mounting holes 18 are provided on both sides of the mounting groove 311 for easy connection with the subsequent inclined beam 11 .

[0024] Assemble the roof frame: like Figure 1 As shown, the roof frame 1 is composed of a plurality of inclined beams 11 and transverse beams 12. Two inclined beams 11 are connected at the ridge as a group and are inclined from the ridge to the eaves to form a gable roof with two slopes.

[0025] In order to facilitate construction and assembly, the ends of the two inclined beams 11 in this solution are connected and fixed by the inclined beam ridge connection assembly 4. Specifically, Figure 2 and 3 As shown, each group of inclined beam ridge connection components 4 includes two connectors 41, each connector 41 is composed of two U-shaped connecting plates 42, the two sides of the U-shaped connecting plates 42 are bent outward in opposite directions to form a joint 43, and a mounting hole 18 is provided on the joint 43. The mounting holes 18 on the two U-shaped connecting plates 42 of the same group correspond to each other and are equal in number. The number of mounting holes 18 on each joint 43 is at least one, and in order to enhance the firmness, it can also be set to multiple. In this embodiment, the number of mounting holes 18 on each joint 43 is 2. In addition, a connecting ear 44 is formed at the inner end of the connector 41, and a mounting hole 18 is also provided on the connecting ear 44. The mounting hole 18 on the connecting ear 44 is used to connect the two connectors 41.

[0026] During construction and assembly, the inclined beam 11 is first embedded in the installation groove 311 of the column 31, and the inclined beam 11 is connected and fixed to the column 31 by the fasteners 19 and the installation holes 18; then the two U-shaped connecting plates 42 are snapped together on both sides of the inner end of one inclined beam 11 as a group, and the fasteners 19 are used to pass through the corresponding installation holes 18 on the joint 43 and locked, and the second inclined beam 11 and the second group of U-shaped connecting plates 42 are fixed. There is no need to cut the bevel angle of the inclined beam 11 or weld it. Instead, the ends of the two inclined beams 11 fixed with the connecting heads 41 are aligned, and the mounting holes 18 of the connecting ears 44 on the two connecting heads 41 are aligned, and then another fastener 19 is used to pass through the mounting holes 18 on the connecting ears 44 and locked, so that the assembly of a group of inclined beams 11 is completed, and the above-mentioned connection operation of the inclined beams 11 is repeated until all the inclined beams 11 are laid; The fasteners 19 described in this case are preferably high-strength, corrosion-resistant bolt and nut sets to ensure the stability and durability of the connection assembly. The bolt and nut sets are detachable fasteners, which not only make it easy to connect the parts connected by them, but also can be removed and reassembled at any time in the event of assembly errors. The angle of the inclined beam 11 can also be freely adjusted by loosening the fasteners 19, which is more flexible in use, faster to install, more efficient in construction, and lower in labor costs.

[0027] Then assemble the crossbeam 12: Figure 1 and 4 As shown, the cross beams 12 in the roof frame 1 are arranged on the diagonal beams 11 at intervals and are parallel to the length direction of the roof ridge. The connection between the diagonal beams 11 and the cross beams 12 is fixed by the cross diagonal beam clamp assembly 8. Figure 5 As shown, the cross beam clamp assembly 8 includes an I-shaped plate 81 and two U-shaped pieces 82. The I-shaped plate 81 is attached to the cross beam 12. The two U-shaped pieces 82 surround the diagonal beam 11 from below and are connected to the I-shaped plate 81, thereby fixing the diagonal beam 11 and the cross beam 12. Repeat the above operation until all cross beams 12 are assembled.

[0028] Assemble the waterproof frame: like Figure 6 As shown, the waterproof frame 2 is composed of a plurality of U-shaped gutters 21 mounted on the crossbeam 12. Two U-shaped gutters 21 are connected at the ridge as a group and tilted from the ridge to the eaves, in a state parallel to the inclined beam 11. The connection between the crossbeam 12 and the U-shaped gutters 21 is fixed by a U-shaped gutters clamp assembly 9. The U-shaped gutters clamp assembly 9 also adopts a combination of an upper "J"-shaped plate and a lower U-shaped piece. Figure 6 and Figure 7 .

[0029] Also for the convenience of assembly, the ends of the two U-shaped gutters 21 in this solution are connected by a U-shaped gutters ridge connection assembly 10. Figure 8 and Fig. 9 As shown, the U-shaped gutter ridge connection assembly 10 includes two U-shaped connection seats 101, and the two sides of the U-shaped connection seats 101 are bent outward in opposite directions to form a mounting portion 102. The mounting portion 102 is provided with a mounting hole 18, and the mounting hole 18 on the mounting portion 102 corresponds to the mounting hole 18 on the U-shaped gutter 21. The number of mounting holes 18 on each mounting portion 102 is at least one, and in order to enhance the firmness, it can also be set to multiple. In this embodiment, the number of mounting holes 18 on each mounting portion 102 is 3. In addition, a transfer ear 103 is formed at the inner end of the U-shaped connection seat 101, and the transfer ear 103 is also provided with a mounting hole 18. The mounting hole 18 on the transfer ear 103 is used to connect the two U-shaped connection seats 101.

[0030] During construction and assembly, the U-shaped connection seat 101 is placed below the inner end of the U-shaped water tank 21, so that the inner end of the U-shaped water tank 21 is embedded in the U-shaped connection seat 101, and then 6 sets of fasteners 19 are used to match the mounting holes 18 on the overlapped portion to fix the U-shaped water tank 21 to the U-shaped connection seat 101, and then the operation is repeated to fix the second U-shaped water tank 21 and the U-shaped connection seat 101. After all are fixed, the two U-shaped water tanks 21 are overlapped in an offset manner, so that the transfer ears 103 on the two U-shaped connection seats 101 are aligned, and the fasteners 19 are matched with the mounting holes 18 to fix them, and the assembly of the two U-shaped water tanks 21 is completed. Similarly, the angle of the U-shaped water tank 21 can be adjusted by loosening and tightening the fasteners 19.

[0031] After the two U-shaped gutters 21 are assembled, a U-shaped gutters ridge cover 5 is placed on the joint between the two. The outer periphery of the U-shaped gutters ridge cover 5 matches the shape of the inner peripheral wall of the U-shaped gutters 21. Fig.10 After covering, the waterproof property of the U-shaped water tank 21 can be improved to prevent water from leaking from the connection, and at the same time, it will not interfere with the installation of other components.
