[0029] The utility model provides a fixing structure for installing a photovoltaic panel to a roof bracket, as shown in the attached Figure 1 and 3 As shown, the fixed structure includes a drain beam 11, a photovoltaic panel 2 and a mounting assembly. The drain beam 11 is fixed to the roof support, or the drain beam 11 can be a rod body that replaces the roof support during the construction phase of the roof support and is welded to the roof support. The photovoltaic panel 2 is installed between two adjacent drain beams 11, and the photovoltaic panel 2 and the drain beam 11 are connected and fixed by the mounting assembly.

[0030] As attached Figure 2 and 4 As shown, the drain beam 11 is hollow inside and penetrated at both ends. Specifically, the drain beam 11 can be a hollow pipe. Partitions 111 are provided on both sides of the upper surface of the drain beam 11, and a strip-shaped water inlet is also provided between the two partitions 111. The water inlet extends into the drain beam 11. Preferably, the two ends of the water inlet extend close to the two ends of the drain beam 11, or the two ends of the water inlet can penetrate outside the two ends of the drain beam 11. The structure of the drain port 101 enables the drain beam 11 to receive rainwater, that is, rainwater enters the drain beam 11 from the drain port 101 and flows downward from the drain beam 11, avoiding rainwater from existing between two adjacent photovoltaic panels 2 on the drain beam 11. Furthermore, a drainage trough 12 can be fixed at the lower end of the drain beam 11 on the roof bracket. The drainage trough 12 is connected to the lower end of each drain beam 11, so that the rainwater discharged from each drain beam 11 can flow downward into the drainage trough 12 uniformly, and then flow out from both ends of the drainage trough 12.

[0031] Continue to refer to the attached Figure 4 , both sides of the photovoltaic panel 2 are provided with recessed pressing grooves 201, and when the photovoltaic panel 2 is placed between two row beams 11, the side of the pressing groove 201 of the photovoltaic panel 2 is correspondingly attached to the partition 111. Furthermore, the side of the partition 111 is fixed with a sealing gasket 112, and the side of the photovoltaic panel 2 is tightly attached to one side of the sealing gasket 112, so that the gap between the photovoltaic panel 2 and the partition 111 can be sealed.

[0032] As attached Figure 4 and 5As shown, the installation assembly includes a fastening nut 34, a first pressing piece 31, a second pressing piece 32 and a fixing screw 33. The fastening nut 34 is placed in the drain beam 11, and the outer diameter of the fastening nut 34 is larger than the width of the water inlet. When installing, the fastening nut 34 can be vertically placed in the drain beam 11 and then placed horizontally so that the fastening nut 34 cannot be directly pulled out. A fixing knob or a hexagonal screw head is fixed at one end of the fixing screw 33. Figure 6 The sides of both sides of the first pressing member 31 are provided with guide parts 35, and the lower ends of the guide parts 35 are provided with inclined guide surfaces. Figure 7 The guide part 35 and the stopper 36 are respectively arranged on both sides of the second pressing member 32, and the stopper 36 of the second pressing member 32 is parallel to the guide part 35, and the bottom surface of the stopper 36 is recessed to form a clearance groove 361. In addition, a plurality of positioning grooves 102 are arranged on the side of the partition 111, and the stopper 36 is provided with a positioning part 362 in the clearance groove 361. When the clearance groove 361 of the stopper 36 is adapted to be inserted into the partition 111, the positioning part 362 is adapted to be inserted into the positioning groove 102. Through this structure, the stopper 36 can be restricted to the partition 111 and cannot move left and right or slide up and down relative to the partition 111.

[0033] The method of installing the photovoltaic panel 2 using the above-mentioned fixing structure is as follows:

[0034] When photovoltaic panels 2 are installed on both sides of the drainage beam 11, as shown in the attached Figure 8 As shown, the fastening nut 34 can be placed in the drain beam 11 first, and then the photovoltaic panels 2 are placed on both sides of the drain beam 11. After that, the first pressure piece 31 is placed between the two photovoltaic panels 2, and the fixing screw 33 is passed through the first pressure piece 31 and then through the water inlet and the fastening nut 34 to be screwed until it is tightened, so that the fixing screw 33 presses the first pressure piece 31 toward the photovoltaic panel 2, and the guide slope 351 is embedded in the pressing groove 201 to pull the two photovoltaic panels 2 on both sides of the drain beam 11 toward the middle of the drain beam 11, so that the two photovoltaic panels 2 are pulled toward the two partitions 111 respectively, so that the photovoltaic panels 2 are only attached to the partitions 111 and are pressed downward by the first pressure piece 31.

[0035] When the drainage beam 11 on the outer side of the roof support is installed and connected to the photovoltaic panel 2, if the photovoltaic panel 2 is installed horizontally from the inner side of the roof support to the outside, at this time, one side of the photovoltaic panel 2 close to the outer row has been fixed by the inner drainage beam 11, so it can be directly installed as shown in the attached figure. Fig. 9As shown, the fastening nut 34 is placed in the drainage beam 11 on the outer side, and then the second pressure piece 32 is lowered on the side drainage beam 11, and the guide slope 351 of the guide part 35 of the second pressure piece 32 is inserted into the pressing groove 201 of the photovoltaic panel 2, and the yield groove 361 of the limiting part 36 of the second pressure piece 32 is inserted into the partition 111 of the drainage beam 11, and then the fixing screw 33 is passed through the second pressure piece 32 and then through the water inlet and the fastening nut 34 to be tightened, so that the fixing screw 33 presses the second pressure piece 32 toward the photovoltaic panel 2, so that the guide slope 351 of the guide part 35 on one side of the second pressure piece 32 is inserted into the pressing groove 201, and at the same time, the limiting part 36 on the other side of the second pressure piece 32 is pressed tightly on the partition 111, so as to realize the installation and fixation of the photovoltaic panel 2 and the roof bracket located on the outer side of the roof bracket.

[0036] It is worth mentioning that when installing the photovoltaic panels 2 on the side of the drain beam 11, they can be installed one by one from the bottom of the drain beam 11 upwards. When installing the first photovoltaic panel 2 at the bottom, first drive the screws 13 into the upper surface below the drain beam 11, then place the photovoltaic panel 2 on the upper surface of the drain beam 11, and use the screws 13 to block the photovoltaic panel 2 to prevent the photovoltaic panel 2 from sliding down and falling on the ground. Afterwards, when arranging and installing upwards, the lowest photovoltaic panel 2 can form a barrier to prevent the photovoltaic panel 2 from sliding down before being fixed during installation. No other operators are required to help block the photovoltaic panel 2, so this method of installation is more convenient.

[0037] In summary, in the structure of the utility model, the first pressure piece 31 and the second pressure piece 32 can be pressed down to the drain beam 11 by screwing the fixing screw 33 downward into the fastening nut 34 located in the drain beam 11, so that the side of the photovoltaic panel 2 is pressed and fixed on the drain beam 11, and the guide slope 351 is embedded in the pressing groove 201 of the photovoltaic panel 2 to pull the photovoltaic panel 2 to the sealing gasket 112 fixed to the partition 111 close to the drain beam 11, so that the gap between the drain beam 11 and the side of the photovoltaic panel 2 fits tightly and is sealed, thereby preventing rainwater from leaking downward from the gap between the photovoltaic panel 2 and the drain beam 11. When the photovoltaic panel 2 needs to be replaced later, the fixing screw 33 can be unscrewed and the first pressure piece 31 and the second pressure piece 32 can be removed to separate the connection between the photovoltaic panel 2 and the drain beam 11, which is very convenient.

[0038] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
