[0037] 1. This method reduces the necessary opening or cutting steps in traditional assembly. The assembly can be completed only through the installation grooves and fastening bolts, which not only simplifies the construction process, improves work efficiency, but also reduces the requirements for the professional skills of construction workers. Workers only need to receive simple training on the installation positions of components to be competent for the work, thus effectively reducing labor costs.

[0038] 2. The profiles used in this scheme have different specifications and have been classified before leaving the factory. Workers only need to distinguish and cut the required profiles according to the construction drawings, further shortening the construction time and reducing labor costs. In contrast, the traditional scheme uses square tubes of uniform specifications, which not only need to be cut on site according to the construction drawings, but also often cause material waste, increased construction time and rising labor costs due to misoperations by workers.

[0039] In summary, the assembly method of the photovoltaic support system of the present invention brings substantial improvements to the installation of photovoltaic supports with its characteristics of high efficiency, simplicity and cost savings. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0075] The present invention provides a photovoltaic support system and an assembly method thereof, as Figures 2 to 22 shown. The photovoltaic support includes a support frame and a herringbone roof frame erected on the support frame. Among them, the support frame includes a plurality of columns 2 and transverse beams 3, and the transverse beam 3 is connected to the column 2 through a first connecting member 91. The roof frame includes a plurality of inclined beams 5 and cross beams 6. The inclined beam 5 is connected to the column 2 through a second connecting member 92, and the cross beam 6 is connected to the inclined beam 5 through a third connecting member 93.

[0076] Referring to Figure 3 and Figure 4 , including but not limited to the profiles 1 used as the columns 2, inclined beams 5, cross beams 6 and transverse beams 3, a plurality of mounting grooves 12 with a T-shaped cross section are provided on the outer surface of the main body 11 of the profile 1. The fastening assembly 10 is used to cooperate with the mounting groove 12 between each connecting member 9 and the profile 1 to achieve a fixed connection. As Figure 8 shown, the fastening assembly 10 includes a bolt 101 and a nut 102. An installation hole 9-1 for the bolt 101 to pass through is provided on the connecting member 9. The head of the bolt 101 is limited in the mounting groove 12 of the profile 1, and the rod portion of the bolt 101 passes through the installation hole 9-1 on the connecting member 9 and is fastened by the nut 102, thereby realizing the connection and fixation of each profile 1 and the connecting member 9.

[0077] In order to further improve the efficiency and flexibility of on-site assembly construction. As Figure 3 shown, in this solution, the mounting groove 12 is designed to extend along the length direction of the main body 11 of the profile 1, so as to provide a wide and flexible sliding space for the bolt 101, enabling it to move freely along the length direction in the mounting groove 12, thereby providing as many mounting point selection options as possible to ensure that the bolt 101 can achieve a stable fixing effect at each ideal position. In addition, lateral notches are provided on both sides of the mounting groove 12 to facilitate the head of the bolt 101 to enter and exit the mounting groove 12.

[0078] The main body 11 of the profile 1 is usually designed as a hollow structure, but this design is not an absolute necessary limitation condition. It can be flexibly adjusted according to actual application requirements. The main advantage of adopting the hollow main body 11 structure is that it is beneficial to greatly reduce the overall weight, thereby improving the handling and installation efficiency of the photovoltaic support; at the same time, the hollow design can also effectively improve the material utilization rate, reduce the cost-benefit, and make the manufacturing of the photovoltaic support more economical and efficient. In addition, the hollow structure provides greater flexibility for the profile 1, facilitating plug-in assembly with components such as the base 7 and the connecting member 9.

[0079] Regarding the shape of the cross section of the profile 1, we provide a variety of designs, including but not limited to options such as quadrilateral, pentagon, hexagon, and octagon, as Figure 6As shown, the selection of these shapes is completely based on actual assembly requirements and scenario applications. This solution does not make specific limitations on this to ensure maximum flexibility and adaptability. In this solution, according to needs, the profile 1 with an octagonal cross-section is selected as the column 2, and the profile 1 with a rectangular cross-section is selected as the diagonal beam 5, the cross beam 6, and the transverse tension beam 3.

[0080] Regarding the number of mounting grooves 12 distributed on the outer periphery of the main body 11 of the profile 1, as Figure 6 shown, it includes but is not limited to two, three, or four mounting grooves 12. The specific number also depends on the assembly requirements and application scenarios. In this solution, the column 2 has four mounting grooves 12, both the diagonal beam 5 and the cross beam 6 have three mounting grooves 12, and the transverse tension beam 3 is provided with two mounting grooves 12.

[0081] This solution has also made significant improvements to the structure of the profile 1, as Figure 4 and Figure 5 shown, the connection between the mounting groove 12 and the main body 11 on the profile 1 in this solution has a J-shaped structure 13. Specifically, the J-shaped structure 13 includes a horizontal side 131 and two vertical sides. The first vertical side 132 and the second vertical side 133 are located at both ends of the horizontal side 131 and extend parallel in the same direction from both ends of the horizontal side 131. During the processing, these components are integrally formed with the main body 11. Compared with the traditional sharp bending angle, this J-shaped transition structure can effectively disperse stress, greatly reduce the stress concentration phenomenon, so that the stress distribution at the connection is more uniform and reasonable. This design not only significantly improves the anti-fatigue performance of the profile 1 during use, enhances the structural stability, but also greatly improves the overall bearing capacity and reliability of the photovoltaic support profile 1, providing guarantee for the safe and efficient operation of the photovoltaic support.

[0082] To improve the connection stability, the bolt 101 in the fastening component 10 of this solution uses a T-shaped bolt 101, as Figure 4 and Figure 8 shown, the head of the T-shaped bolt 101 is a parallel hexagon, and one group of parallel sides is the long sides, and the other two groups are the short sides. The cooperation method of the T-shaped bolt 101 with the mounting groove 12 on the profile 1 is as follows: Slide the head of the T-shaped bolt 101 into the lateral notch of the mounting groove 12, and then rotate a certain angle so that its head is stuck in the groove pit of the mounting groove 12. In this way, the T-shaped bolt 101 cannot continue to slide in the mounting groove 12.

[0083] The specific structure of the photovoltaic support system of the present invention is as follows:

[0084] <Support frame>

[0085] As Figure 10As shown, the support frame includes columns 2, horizontal tie beams 3 and diagonal braces 4, which are the key to supporting the roof including the roof frame, photovoltaic modules, etc.

[0086] The columns 2 are distributed in a matrix and supported between the ground and the roof. The columns 2 can be directly fixed to the ground or fixed through a base 7. In this embodiment, a base 7 is provided, as Figure 9 shown, the base 7 includes a base plate 71 and a connecting column 72. The bottom of the base plate 71 is fixed to the ground through fasteners. The middle of the connecting column 72 is shaped to fit the outer periphery of the column 2 for the column 2 to be inserted. Installation holes 9-1 are provided on the side wall of the connecting column 72. Since the column 2 is a profile 1 with installation holes 9-1, during installation, after the bottom of the column 2 is inserted into the connecting column 72, it can be fixedly connected to the base 7 through the cooperation of the fastening assembly 10 with the corresponding installation grooves 12 and installation holes 9-1. In addition, a reinforcing plate for obliquely supporting the two is provided between the outer side wall of the column 2 of the base 7 and the base plate 71.

[0087] The horizontal tie beams 3 are horizontally arranged between the columns 2 at the edge of the matrix, and the horizontal tie beams 3 are connected to the columns 2 through the first connectors 91.

[0088] In this embodiment, the first connector 91 is a U-shaped hoop, as Figure 11 and Figure 12 shown. The middle of the U-shaped hoop is a clamping part for clamping the horizontal tie beam 3, and installation holes 9-1 are provided on both side walls of the clamping part. The two sides of the U-shaped hoop are installation parts, which are parallel to the surface of the column 2 and are provided with installation holes 9-1 for cooperating with the fastening assembly 10.

[0089] The diagonal braces 4 are obliquely arranged between the columns 2 and the horizontal tie beams 3, and the three form a triangular structure. As Figure 10 shown, the upper end of the diagonal brace 4 is connected to the horizontal tie beam 3 through the fourth connector 94. As Figure 13 shown, the fourth connector 94 includes an L-shaped hoop 941 and a U-shaped hoop 942. The L-shaped hoop 941 and the U-shaped hoop 942 are clamped together as shown in the figure. The upper part is used for clamping the horizontal tie beam 3, and the lower part is used for connecting to the diagonal brace 4. Installation holes 9-1 are correspondingly provided at each installation site on the hoop.

[0090] As Figure 10 shown, the lower end of the diagonal brace 4 is connected to the column 2 through the fifth connector 95. As Figure 14 shown, the fifth connector 95 includes a straight hoop, and installation holes 9-1 are correspondingly provided at each installation site on it. The connector and the profile 1 are fixed through the cooperation of the fastening assembly 10 with the installation grooves 12 and installation holes 9-1.

[0091] Here, an L-shaped angle steel can be selected as the diagonal brace 4, or the profile 1 with the installation groove 12 described above can be selected as the diagonal brace 4.

[0092] <Roof skeleton>

[0093] As Figure 15 and Figure 16 shown, the roof skeleton includes a plurality of diagonal beams 5 and cross beams 6.

[0094] The diagonal beam 5 is erected on the top of the column 2 and is inclined from the ridge to the eaves. The diagonal beam 5 and the column 2 are connected by a second connecting member 92. As Figure 15 and 17 shown, the second connecting member 92 is composed of an upper connecting portion and a lower connecting portion. The upper connecting portion is in a U-shaped structure with an upward opening for connecting the diagonal beam 5, and the lower connecting portion is in a ring structure surrounding the column 2 for connecting the column 2. Both the upper connecting portion and the lower connecting portion are provided with installation holes 9-1 for cooperating with the fastening assembly 10.

[0095] For the convenience of production, processing and assembly, the structure of the second connecting member 92 is further improved in this solution. As Figure 17 shown, each group of the second connecting members 92 is composed of two connecting plates 921 with exactly the same structure. These two connecting plates 921 are combined together in a left-right splicing manner and surround the outer periphery of the column 2, thus forming a connection structure that is both stable and firm and easy to assemble. Specifically, each connecting plate 921 adopts an arc-shaped structure design, which enables it to better fit the curved surface of the column 2 and increases the stability and tightness of the connection. On both sides of each connecting plate 921, an extension arm 922 is respectively provided. The left and right extension arms 922 on the same connecting plate 921 are staggeredly distributed in the horizontal direction, that is, one extension arm 922 is on the upper side and the other extension arm 922 is on the lower side. In this way, when the two connecting plates 921 are spliced with the arc-shaped openings facing each other, the extension arms 922 on different sides of the two connecting plates 921 are in an up-down staggered splicing state, forming a ring structure.

[0096] Refer to Figure 18 , the diagonal beams 5 on both sides of the roof are connected by a ridge connecting member 97. Each group of ridge connecting members 97 includes two connecting heads 971. The inner ends of the two diagonal beams 5 are connected through the connecting heads 971, forming a herringbone structure at the ridge of the photovoltaic support. In other words, the outer ends of the two connecting heads 971 are respectively connected to one diagonal beam 5 on the same side, and the inner ends of the two connecting heads 971 are connected to each other by fasteners to connect the two diagonal beams 5. Refer to Figure 19, the cross-section of the connector 971 is U-shaped. This design enables the inclined beam 5 to be well embedded and carried within the U-shaped connector 971. As a result, the ends of the inclined beam 5 are tightly wrapped by the two side plates 973 of the U-shaped connector 971, greatly enhancing the stability and reliability of the connection. Specifically, as Figure 19 shown, the connector 971 is formed by enclosing a bottom plate 972 and two side plates 973, forming a stable U-shaped structure. Installation holes 9-1 corresponding to the installation grooves 12 on the inclined beam 5 are provided on both the bottom plate 972 and the side plates 973, and each installation hole 9-1 corresponds to a set of fasteners.

[0097] The two connectors 971 are connected through connection ears 974. Specifically, the inner ends of the side plates 973 of the connector 971 extend inwards to form connection ears 974, and circular installation holes 9-2 for cooperating with the fasteners are provided on the connection ears 974. The connection ears 974 of the two connectors 971 are connected through the cooperation of the fasteners and the circular installation holes 9-2. The fasteners here can be any bolt 101 and nut 102 assemblies.

[0098] The cross beam 6 is laid on the inclined beam 5 and is in a state parallel to the ridge. The cross beam 6 and the inclined beam 5 are connected by a third connector 93. As Figure 20 shown, the third connector 93 is composed of two U-shaped parts. The bottoms of these two U-shaped parts are connected, and the opening of the upper U-shaped part 931 faces upwards for connecting the cross beam 6, and the opening of the lower U-shaped part 932 faces downwards for connecting the inclined beam 5. Installation holes 9-1 for cooperating with the fastening assembly 10 are provided on the U-shaped parts.

[0099] During assembly, the upper connecting part in the second connector 92 and the lower U-shaped part 932 in the third connector 93 jointly enclose the outer periphery of the inclined beam 5, and the third connector 93 is inside (closer to the inclined beam 5), while the second connector 92 is outside. In other words, during assembly, the installation holes 9-1 on the upper connecting part of the second connector 92 correspond to the installation holes 9-1 on the lower U-shaped part 932 of the third connector 93, forming corresponding hole groups one by one. Each group of corresponding installation holes 9-1 is tightly connected through a set of bolt 101 and nut 102 assemblies. This design not only ensures the installation accuracy but also significantly improves the firmness and stability of the overall structure.

[0100] Compared with the existing method of locking and surrounding the profile 1 through the connector 9, the stability of the structure is stronger in the present solution by the way of the installation groove 12 cooperating with the fastening assembly 10 to lock the connector.

[0101] <Drainage layer>

[0102] The drainage layer is composed of several U-shaped water troughs 8, as Figure 21As shown, the U-shaped water trough 8 is arranged on the cross beam 6 and is inclined from the ridge to the eaves. The U-shaped water trough 8 is connected to the cross beam 6 through the sixth connecting member 96 and is fixed by cooperating with the mounting groove 12 on the cross beam 6 through the fastening assembly 10. As Figure 22 As shown, the sixth connecting member 96 includes a U-shaped hoop. The middle part of the U-shaped hoop is a clamping part that surrounds the U-shaped water trough 8. The clamping part has undulations 961 that adapt to the upper surface of the U-shaped water trough 8, so that it can perfectly fit the upper surface of the U-shaped water trough 8, effectively preventing the slipping phenomenon that may occur under the impact of water flow or the action of wind, and greatly improving the overall stability. The middle part of the U-shaped hoop extends to both sides to form a mounting part parallel to the surface of the cross beam 6. Mounting holes 9-1 for cooperating with bolts 101 are provided on the mounting part.

[0103] The mounting holes 9-1 on the connecting member 9 described in this case can be selectively set as runway-shaped mounting holes 9-3 or circular mounting holes 9-2. The mounting holes for cooperating with ordinary bolts 101 are preferably circular mounting holes 9-2, and the mounting holes for cooperating with T-shaped bolts 101 are preferably runway-shaped mounting holes 9-3. The design of the runway-shaped mounting holes 9-3 allows for a certain degree of fine adjustment during the installation process, ensuring the precise alignment and tight fit between the profile 1 and the connecting member 9.

[0105] Preparation before assembly: Select profiles 1 of the required size as the columns 2, inclined beams 5, cross beams 6, and transverse tension beams 3. In addition, before assembling the main profiles 1, some fastening assemblies 10 can be pre-assembled on the connecting member 9, that is, the bolts 101 are inserted into the mounting holes 9-1, and the nuts 102 are locked but not tightened, as Figure 12 shown. This is because, depending on the structure, some fastening assemblies 10 need to be pre-assembled on the connecting member 9 for smooth installation, while some fastening assemblies 10 need to connect the connecting member 9 and the profile 1 first, and then insert the bolts 101 and lock the nuts 102.

[0106] Installation of column 2: Pre-assemble the fastening assembly 10 on the mounting hole 9-1 of the base 7, then align the mounting groove 12 of the column 2 with the bolt 101 on the base 7, insert it into the connecting column 72 of the base 7, and lock the nut 102 after insertion, refer to Figure 9 ;

[0107] Installation of transverse tension beam 3: Install the mounting part of the U-shaped hoop in the first connecting member 91 on the column 2 through the fastening assembly 10, then insert the transverse tension beam 3 through the middle part of the U-shaped hoop, and lock the nut 102 after adjusting to the required position, refer to Figure 10 ;

[0108] Installation of the diagonal brace 4: Fix the fourth connecting piece 94 on the cross beam 3. Then fix the fifth connecting piece 95 below the first connecting piece 91 (at a position about 500 - 600 mm) that has been fixed on the column 2. Next, fixedly connect the upper end of the diagonal brace 4 to the fourth connecting piece 94 and the lower end to the fifth connecting piece 95. Refer to Figure 10 。

[0109] Installation of the inclined beam 5 and the cross beam 6:

[0110] Pre - assemble the fastening assembly 10 on the second connecting piece 92 and the third connecting piece 93.

[0111] Connect the lower connecting part of the second connecting piece 92 to the upper end of the column 2, and then pass the inclined beam 5 through the upper connecting part of the second connecting piece 92 on the column 2. Next, embed the lower U - shaped part 932 of the third connecting piece 93 into the upper connecting part of the second connecting piece 92.

[0112] Finally, pass the cross beam 6 through the upper U - shaped part 931 of the third connecting piece 93 and adjust it to the required position. After the above - mentioned structure is connected, lock the nuts 102 at each place. Refer to Figure 15 。

[0113] Connection of the inclined beam 5 at the ridge:

[0114] First, pre - assemble the fastening assembly 10 on the ridge connecting piece 97. Then connect a connecting head 971 to the inner end of each inclined beam 5, lock the connecting ears 974 of the corresponding two connecting heads 971 through fasteners, and then lock the nut 102 of the fastening assembly 10. Refer to Figure 18 。

[0115] It should be noted that the installation sequence of the above - mentioned profiles 1 and connecting pieces 9 is not fixed, and can be adjusted according to actual requirements and installation convenience.
