Then, the brackets are installed on the raised brackets, and the photovoltaic panels are installed on the top of the brackets.

[0004] Since the lifting support is a single structure, although it can meet the requirements of complex roof structures, the installation of each one is time-consuming and inconvenient. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A photovoltaic installation auxiliary frame for BIPV roofs includes a beam assembly 1, a connecting beam 3 is provided inside the beam assembly 1, and a longitudinal beam 2 is welded between the connecting beam 3 and the beam assembly 1. The beam assembly 1, the connecting beam 3 and the longitudinal beam 2 constitute a frame structure.

[0028] The crossbeam assembly 1 includes a galvanized steel square tube 101. Multiple cable insertion holes 102 are provided on both the front and rear sides of the galvanized steel square tube 101, and multiple top openings 103 are provided on the top of the galvanized steel square tube 101 and multiple bottom openings 104 are provided on the bottom of the galvanized steel square tube 101.

[0029] The longitudinal beam 2 includes a galvanized steel square tube 101 and cable insertion holes 102 opened on the front and rear sides of the galvanized steel square tube 101.

[0030] The connecting beam 3 includes a galvanized steel square tube 101, cable insertion holes 102 on the front and rear sides of the galvanized steel square tube 101, a top opening 103 on the top of the galvanized steel square tube 101, and a bottom opening 104 on the bottom of the galvanized steel square tube 101.

[0031] By adopting the above technical solution, an auxiliary frame is welded according to the shape and size of the photovoltaic panel 4. The crossbeam assembly 1 is fixed to the roof with bolts. The bolts pass through the bottom opening 104 of the crossbeam assembly 1 and are fixed into the roof. The bottom opening 104 and the top opening 103 are set to correspond to each other to facilitate the installation of bolts. Bolts can be set at the four corners of the auxiliary frame. In order to increase the stability of the auxiliary frame, a small number of bolts can be added in the middle of the crossbeam assembly 1. The photovoltaic panel 4 is installed on the top opening 103 of the connecting beam 3 with bolts. The nuts on the bolts are located at the bottom of the bottom opening 104 to lock the bolts. The auxiliary frame formed by welding the crossbeam assembly 1, the longitudinal beam 2 and the connecting beam 3 facilitates the installation of the photovoltaic panel 4. The crossbeam assembly 1, the longitudinal beam 2 and the connecting beam 3 can be freely welded according to the shape of the photovoltaic panel 4, so as to flexibly handle the actual installation situation. Compared with the need to install and raise the brackets one by one, the installation is more convenient, and the auxiliary frame is a whole, which has higher stability.

[0032] Specifically, such as Figure 1 and Figure 5 As shown, an adjustment component 5 is provided at the bottom of the connecting beam 3. The adjustment component 5 includes a central connecting nut 502 fixed inside the connecting beam 3. A lifting screw 503 is threadedly connected to the interior of the central connecting nut 502.

[0033] The top of the lifting screw 503 is welded with a nut head 504, and the bottom of the lifting screw 503 is fixed with a rubber base 501.

[0034] A photovoltaic panel 4 is installed above the crossbeam assembly 1, the longitudinal beam 2 and the connecting beam 3, and the middle connecting nut 502 is fixed inside the bottom opening 104.

[0035] Bottom opening 104, top opening 103 and cable insertion hole 102 are evenly distributed at equal intervals along the surface of galvanized steel square tube 101.

[0036] By adopting the above technical solution, the adjustment component 5 is set on the bottom opening 104, avoiding the position of the bolts on the photovoltaic panel 4. When setting the adjustment component 5, there is a bottom opening 104 in the middle. The bottom opening 104 without the adjustment component 5 is used to pass bolts through to fix the photovoltaic panel 4. After the auxiliary frame is installed, the height of the auxiliary frame can be adjusted according to the actual laying condition of the roof. When leveling, the nut head 504 is rotated by a tool. Since the middle connecting nut 502 is fixed inside the bottom opening 104, when the nut head 504 is rotated, it can drive the lifting screw 503 to rotate. Thus, the lifting screw 503 pushes the rubber base 501 to move downward, so that the rubber base 501 is close to the roof plane. Through the setting adjustment component 5, the lifting screw 503 can be driven to rotate under the action of the nut head 504, thereby pushing the rubber base 501 to move downward, so that the rubber base 501 is close to the roof plane, and the auxiliary frame is leveled.

[0037] Working principle:

[0038] The auxiliary frame is welded according to the shape and size of the photovoltaic panel 4. The auxiliary frame, which is welded by the crossbeam assembly 1, the longitudinal beam 2 and the connecting beam 3, is fixed to the roof through the crossbeam assembly 1. The bolts pass through the bottom opening 104 of the crossbeam assembly 1 and are inserted into the roof for fixation. The bottom opening 104 and the top opening 103 are set to correspond to each other to facilitate the installation of bolts.

[0039] Before installing the photovoltaic panel 4, the auxiliary frame is leveled. The nut head 504 is rotated by a tool. Since the middle connecting nut 502 is fixed inside the bottom opening 104, when the nut head 504 is rotated, it can drive the lifting screw 503 to rotate, thereby pushing the rubber base 501 downward through the lifting screw 503, so that the rubber base 501 is close to the roof plane.

[0040] 3. The photovoltaic panel 4 is installed on the top opening 103 of the connecting beam 3 by bolts. The bolts pass through the bottom opening 104 corresponding to the top opening 103. The nut on the bolt is located at the bottom of the bottom opening 104. Tighten the bolt to fix the photovoltaic panel 4. The cables required for the photovoltaic panel 4 can be connected by passing them through the cable entry hole 102 of the crossbeam assembly 1, the longitudinal beam 2 and the connecting beam 3.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
