[0002] The newly installed capacity of photovoltaic in China has been increasing year by year, and distributed photovoltaics have developed rapidly. With the support of the carbon peak and carbon neutrality policies, the demand in the building photovoltaic industry represented by BAPV (behind-the-panel photovoltaic) and BIPV (building-integrated photovoltaic) has been accelerating. In the current market, BAPV has become the mainstream form of building photovoltaics due to its advantages of simple installation, operation, and maintenance, and can be used for the renovation of existing roofs. Moreover, China has a vast amount of existing roof resources, and using BAPV behind-the-panel photovoltaic objectively better meets the development needs of distributed photovoltaics at the current stage.

[0052] The photovoltaic support in the embodiment of the present invention can realize the movement of the leg part along the X-axis and Y-axis, the adjustment of the height along the Z-axis, and the rotation of the support clamp around the Z-axis. The adjustment directions are as Figure 5 shown.

[0053] The inner sleeve 8 of the leg in the embodiment of the present invention slides along the groove rail (i.e., the Y-axis) at the bottom of the lower support beam 5 through angle codes and bolts; the lower support beam 5 and the leg as a whole slide along the bottom groove rail (i.e., the X-axis) of the upper support beam 4 through angle codes and bolts, as Figure 6 shown.

[0054] Figure 11 It is a general overview of the distribution and installation of each component of the photovoltaic support system. The photovoltaic support of the present invention is a four-dimensional adjustable modular support that can adapt to a double-sided standing seam roof. In order to realize any change in the angle of the support arrangement direction and the position of the legs, the following steps are adopted to complete the installation:

[0055] The first step: First, connect the upper and lower support beams through angle codes, and the mating planes of the components are butted and fixed so that the top surfaces of the two upper support beams 4 directly bearing the photovoltaic panels are maintained in the same plane, facilitating the subsequent installation of the photovoltaic panels;

[0056] The second step: Place the standing seam clamp on the roof panel, position it to avoid unfavorable support positions under the panel, and tighten the sixth bolt 1101.

[0057] Step 3: Connect the inner sleeve 8 of the outrigger to the bottom slot rail 12 of the lower supporting beam 5 through the π-shaped connector 7, and connect the bottom of the outer sleeve 9 to the placed upright lock-edge fixture through the inverted π-shaped connector 10 with tooth grooves.

[0058] After the installation is completed, enter the adjustment steps, which are as follows:

[0059] 1. First, adjust the insertion position of the height rough adjustment bolt 901 of the outrigger, and tighten it after fixing the height.

[0060] 2. Then adjust the two height fine adjustment bolts 1001, and tighten them so that the transverse teeth 10061 of the attached tooth gasket 1006 are stuck into the transverse tooth grooves 1005 for fixation. If a certain height difference is left between the two bolts, the inverted π-shaped connector 10 can be tilted at a certain angle to fit the inclined top surface of the fixture due to the change in the roof curvature.

[0061] 3. After the inner sleeve 8 of the outrigger and the lower supporting beam 5 are connected by the fixed angle brackets, they can slide freely in two directions in the plane to align with the fixture placed on the roof panel. Among them, the lower supporting beam slides along the lower slot rail 12 of the upper supporting beam 4 through the first bolt 603, and the outrigger slides along the lower slot rail 12 of the lower supporting beam 5 through the third bolt 701.

[0062] 4. After the planar position of the outrigger is adjusted, a certain angle will be generated between the upper supporting beam 4 and the lower supporting beam 5. Its rotation mode is that the upper supporting beam 4 rotates around the central bolt of the first connecting angle bracket 601, and the second connecting angle bracket 602 has a bolt chute 605 to adapt to the change in the angle, as Figure 8 shown. Tighten the two first bolts 603 to fix the translational relationship and rotational relationship between the upper supporting beam 4 and the lower supporting beam 5.

[0063] 5. After the position of the outrigger is adjusted, a rotation angle around the Z-axis will be formed between it and the roof panel fixture 11. Tighten the four fifth bolts 1002 between the inverted π-shaped connector 10 and the fixture to fix its rotation angle.

[0064] Figure 12 It is a schematic diagram of the installation of the photovoltaic support on the upright lock-edge plate. The laying direction of the photovoltaic panel and the direction of the upright lock-edge plate are shown at an angle of 11°.

[0065] Step 4: After adjusting the support, first install the two side pressing plates 3 on one end of the upper supporting beam 4, then place the first photovoltaic panel 1, and use two middle pressing plates 2 to connect and fix the photovoltaic panel 1 and the top surface of the upper supporting beam 4. Then place the second photovoltaic panel 1, and finally fix it with two side pressing plates 3 at the other end of the upper supporting beam 4, and tighten the pressing plate screws. Figure 13 It is a schematic diagram of the installation of the photovoltaic panel 1 on the support.

[0066] A complete bracket and the photovoltaic panel 1 on it constitute a single photovoltaic module. The number of photovoltaic panels 1 on a bracket can be adjusted as needed. Two photovoltaic panels 1 are illustrated above, and there can also be multiple panels arranged side by side. At this point, the installation of a single photovoltaic module is completed. In accordance with the surface height, shape and size of the roof panel, multiple photovoltaic modules can be set up on the same roof panel, and other brackets can be installed according to the above method to form other photovoltaic modules. Different photovoltaic modules have different inclinations, directions, positions, etc.

[0067] In the embodiment of the present invention, the toothed gasket 1006 is inserted into the transverse tooth groove 1005 at different positions to finely adjust the height of the bracket, with an accuracy of up to 1mm. The fixing positions of the two height fine-adjusting bolts 1001 can also be adjusted separately. When the fixing height positions of the two bolts are inconsistent, the inverted π-shaped connector 10 and the clamp thereunder can be tilted at a certain angle, so that the clamp can be completely fitted and fixed on the plate rib when the upright lock edge plate is bent. The lower planes of the upper support beam 4 and the lower support beam 5 are both provided with groove rails 12, which can make the lower connected leg part slide freely along the support beam in two directions; the leg position can be positioned at any point in the plane of the photovoltaic unit. The angle code connecting the upper support beam 4 is provided with a bolt slide 605 for the screw to slide, so as to adapt to the angle deviation caused by the lateral adjustment of the lower leg. The vertical leg is composed of two inner and outer sleeves, and the inner and outer sleeves are connected by a screw plug hole, wherein the outer sleeve 9 is provided with a plurality of plug holes of different heights, and the coarse adjustment of the vertical height of the leg is achieved by changing the bolt insertion position.

[0068] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
