[0037] In the above structure, refer to Figure 3 The bottom of the front column bracket and the rear column bracket are respectively provided with a metal airtight adsorption component 100, which is used for the photovoltaic bracket to be installed on the concrete roof. The metal airtight adsorption component mainly includes a metal adsorption shell 110, which is disc-shaped and can form a closed space between the bottom and the roof when bonded to the roof. An air extraction port is opened on the surface, and a rubber sealing plug 130 is provided in the air extraction port.

[0038] Specifically, in this embodiment, the two ends of the rubber sealing plug 130 are respectively provided with a rubber top sealing cover 120 and a rubber inner sealing cover 140, which are used for limiting the position of the rubber sealing plug 130 and sealing the inside and outside, and are both made of penetrable rubber material. The roof needs to be processed before installation, and the roof is smoothed with building mortar or building glue. The bonding side of the metal adsorption shell 110 is coated with slow-drying building structure adhesive. After the metal adsorption shell 110 is bonded to the roof, it is vacuumed so that the metal adsorption shell 110 is firmly adsorbed on the roof to achieve installation without damaging the roof. It should be noted that during the operation of the photovoltaic bracket, it is necessary to regularly arrange inspections of the airtightness of the metal airtight adsorption assembly 100 and deal with hazards such as airtightness damage in a timely manner.

[0039] In this embodiment, the structures of the front column bracket and the rear column bracket 300 are basically the same, and each includes an upper column bracket 320, a lower column bracket 310 and an adjustment screw 301. Figure 4, wherein the lower column bracket 310 is a sleeve bracket, and the upper column bracket 320 can be retractably inserted into the lower column bracket 310, and the positions of the upper column bracket 320 and the lower column bracket 310 can be fixed by adjusting the screw 301, so as to achieve the height adjustment of the upper column bracket 320, so as to facilitate the adjustment of the overall angle of the photovoltaic bracket to adapt to different lighting conditions and improve the power generation efficiency and power generation of the photovoltaic panel module 600. It should be noted that when the photovoltaic bracket is installed and repaired and adjusted, each adjustable column bracket can rise and fall a certain height to better adjust the light-facing angle of the entire photovoltaic panel module 600.

[0040] In the above structure, the metal adsorption shell 110 is integrally welded to the lower column bracket 310, and the lower column bracket of the front column bracket and the lower column bracket of the rear column bracket are connected with the inclined rod assembly 200. The inclined rod assembly 200 is hingedly connected to the lower column bracket 310 by bolts through the inclined rod connection assembly 210, and the inclined rod connection assembly 210 is composed of a node plate and bolts to ensure the overall stability of the photovoltaic bracket.

It should be noted that the position of the connecting plates 413 relative to the support beam 400 is adjustable to adapt to the elevation adjustment of the support beam 400. Specifically, the mounting holes on the support beam 400 for mounting the connecting plates are strip holes, and the position of the connecting plates relative to the support beam 400 is changed by installing the adjustable fixing bolts 412 at different positions of the strip holes.

[0042] Reference Figure 2 and Figure 6 The upper end surface of the metal guide rail 500 is provided with a guide rail groove 512, and the lower end surface is provided with an angular clamp groove 513; wherein the angular clamp groove 513 is used to clamp the head of the fastening bolt 511 to achieve the connection between the metal guide rail 500 and the support beam 400, and the guide rail groove 512 is used to cooperate with the pressure block 520 to fix the photovoltaic panel module 600, and the pressure block 520 presses the photovoltaic panel module 600 by bolts, and the nut is limited in the guide rail groove 512, so as to achieve the fixation of the photovoltaic panel module 600. The guide rail groove 512 can be used to perform any lateral adjustment combination on the photovoltaic panel module 600, so as to achieve the quick and convenient installation of the photovoltaic panel module 600. It should be noted that when the photovoltaic panel module 600 is repaired and replaced later, the guide rail groove 512 can also be used to adjust it laterally to achieve the effect of quick repair and replacement.

[0043] Example 2

[0044] This embodiment further improves the air extraction port. Figure 7The shape of the air suction port relative to the lower part in this embodiment is a cone with a diameter gradually decreasing from the outside to the inside, and the shape of the rubber sealing plug 130 is also an inverted cone that matches it. After the vacuum is completed, under the condition of internal negative pressure, the rubber sealing plug 130 shrinks inward under the external atmospheric pressure, and the rubber sealing plug 130 is further compressed by the constraint of the conical air suction port to achieve a self-sealing effect.

[0045] In addition, after the vacuum operation is completed, an oil sealing operation can be performed above the rubber sealing plug 130 in the air suction port to further improve the sealing effect, and a protective cover is provided at the top opening of the air suction port.

[0046] The specific steps for installing the photovoltaic bracket of this embodiment are as follows:

[0047] Step 1: Treat the roof: Use building mortar or building glue to smooth the roof corresponding to the column foot position;

[0048] Step 2: Apply slow-drying building structure adhesive to the bonding side of the bottom surface of the metal adsorption shell 110;

[0049] Step 3: Bond the metal adsorption shell 110 to the roof. After the bonding is firm, perform vacuuming through the air extraction port. Specifically, insert the needle-shaped suction nozzle of the vacuum pump through the rubber sealing plug 130 and then insert it into the inner space of the metal adsorption shell 110 to perform vacuuming. During the insertion of the suction nozzle, the inverted cone-shaped suction port supports the rubber sealing plug 130.

[0050] Step 4: After the vacuum is completed, inject sealing grease above the rubber sealing plug 130 for oil sealing, and cover it with a protective cover;
