[0002] Green development and efficient development will become the future direction of the energy system construction. In current green power technologies, photovoltaic power generation is one of the most important technologies. It can be foreseen that the construction of photovoltaic power stations will be greatly accelerated. Building small photovoltaic power stations on existing building roofs not only realizes the utilization of idle roofs, but also enables the close combination of the power generation side and the user side, minimizing transmission losses to the greatest extent. The current rooftop photovoltaic system is relatively complex in construction and often requires the destruction of the existing roof surface, etc. This not only increases costs, but also damages the original roof waterproof system due to the need to drive fixing nails on the roof surface.

[0017] Further, the installation guide groove and the support connecting rod are fixedly connected by a plurality of positioning screws.

[0018] Further, one end of the support connecting rod is welded to the connecting plate.

[0019] The present invention also discloses an installation method of the photovoltaic module installation device described above, including the following steps:

[0020] S1. First, a plurality of support units are connected in series to form the first row of support rods; repeating S1 forms multiple rows of support rods; the multiple rows of support rods are evenly laid on the roof;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The following further describes the present invention in detail with reference to specific embodiments, which is an explanation rather than a limitation of the present invention.

[0039] As Figures 1-3As shown in the figure, the present invention discloses a photovoltaic module installation device, which includes multiple columns of support rods and multiple positioning rods 6; each column of support rods includes multiple support units connected in series, such as Figures 4-6 As shown, each support unit includes a support connecting rod 2, an installation guide groove 3 and a connecting plate 5. The installation guide groove 3 is fixedly installed above the support connecting rod 2; one end of the support connecting rod 2 is fixedly connected to the connecting plate 5; a first connection hole 7 for penetrating the positioning rod 6 is opened at one end of the connecting plate 5 where it is connected to the support connecting rod 2, and a second connection hole 8 is opened at the other end of the connecting plate 5; a third connection hole 9 is opened at the other end of the support connecting rod 2, and the third connection hole 9 communicates with the second connection hole 8 on the adjacent support connecting rod 2; adjacent two columns of support rods are connected by the positioning rod 6.

[0040] As Figure 2 shown, the odd-numbered support connecting rods 2 arranged in parallel of the i-th column of support rods and the (i + 1)-th column of support rods are connected by the positioning rod 6; the even-numbered support connecting rods 2 arranged in parallel of the (i + 1)-th column of support rods and the (i + 2)-th column of support rods are connected by the positioning rod 6. This makes the positioning rods 6 crosswise arranged, ensuring that the distance between two columns of support rods remains consistent, and at the same time making the entire bottom support structure more stable.

[0041] Specifically, as Figure 4 shown, the support connecting rod 2 is a square steel.

[0042] As Figure 4 shown, one end of the support connecting rod 2 is welded to the connecting plate 5, and the connection is more stable. During on-site installation, only the connecting plate 5 needs to be connected to the head end of another support connecting rod 2, reducing the on-site installation time.

[0043] The installation guide groove 3 is positioned in a structure similar to an I-beam, which is convenient for welding to the lower support connecting rod 2, and at the same time can also hold the photovoltaic module 14.

[0044] Specifically, as Figures 7-8 shown, adjacent two support connecting rods 2 are connected end to end, and the second connection hole 8 of the previous support connecting rod 2 and the third connection hole 9 of the subsequent support connecting rod 2 are fixedly connected by a bolt and nut assembly.

[0045] As Figure 9 shown, the positioning rod 6 is a round rod, and the positioning rod 6 passes through the first connection hole 7 on the connecting plate 5 and the support connecting rod 2 to fixedly connect the two support connecting rods 2 arranged in parallel.

[0046] More preferably, external threads are prefabricated at both ends of the positioning rod 6, and the positioning rod 6 is threadedly connected to the first connection hole 7.

[0047] As Figure 9 shown, nuts 11 are provided at both ends of the positioning rod 6, and flat gaskets 12 and spring gaskets 13 are installed inside the nuts 11.

[0048] As Figure 4 shown, the installation guide groove 3 and the support connecting rod 2 are fixedly connected by a plurality of positioning screws.

[0049] The present invention also discloses an installation method of the photovoltaic module installation device described above, including the following steps:

[0050] S1. First, connect a plurality of support units in series to form a first row of support rods;

[0051] Repeat S1 to form multiple rows of support rods; lay the multiple rows of support rods evenly on the roof 1;

[0052] S2. Install a positioning rod 6 between the multiple rows of support rods to reinforce and connect two adjacent rows of support rods;

[0053] S3. As Figure 10 shown, install the photovoltaic module 14 on the installation guide groove 3 to fully cover the entire roof 1.

[0054] When the roof structure is an inverted V-shaped structure as Figure 1 shown, it is only necessary to fix the support connecting rods 2 symmetrically arranged at the topmost end by bolts.

[0055] The present invention realizes connection and expansion through the cooperation holes between the support connecting rods 2. The photovoltaic module 14 is fixed on the support connecting rod 2 by the installation guide groove 3 and positioning screws welded on the support connecting rod 2. The two rows of support connecting rods 2 are connected by the positioning rod 6 to realize the shaping of the two rows of support connecting rods 2. The single-row quantity and the number of rows of the support connecting rods 2 can be randomly combined according to the size of the roof 1 to realize the laying of the entire roof 1.
