Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket for solar panels. Background Art

[0002] Solar photovoltaic power generation has attracted widespread attention due to its advantages such as cleanliness, safety, convenience, and sustainable development. It has now become an emerging industry that countries around the world are focusing on developing. The main component of solar photovoltaic power generation is the photovoltaic panel, which converts solar radiation energy into electricity.

[0003] Photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are generally made of aluminum alloy, carbon steel and stainless steel.

[0004] In the existing technology, most photovoltaic brackets include purlins, support plates and fastening bolts. There are two parallel purlins, which form a supporting plane and serve as a carrier for the installation of photovoltaic panels. The support plate is fixedly installed on the purlin, and the photovoltaic panel is placed on the support plate. The fastening bolts pass through the support plate and are threadedly connected to the photovoltaic panel to complete the fixation of the photovoltaic panel.

[0005] Regarding the above-mentioned related technologies, in some application scenarios, the photovoltaic bracket needs to be installed on the wall. Currently, most of the purlins are fixed to the wall with screws, but this fixing method has the defect of insufficient firmness, which can easily cause the entire photovoltaic bracket to fall from the wall, so it needs to be improved. Utility Model Content

[0006] In order to facilitate the installation of a photovoltaic bracket on a wall, the present application provides a photovoltaic bracket for a solar panel.

[0007] The photovoltaic bracket for solar panels provided in this application adopts the following technical solutions:

[0008] A photovoltaic bracket for solar panels includes a fixing rod, a limit block, a support plate, a purlin and a clamping assembly, wherein the limit block is provided at one end of the fixing rod, and the end of the fixing rod away from the limit block passes through the wall, and the limit block is used to abut against the wall; the support plate is connected to the fixing rod, and the purlin is connected to the support plate and is used for laying photovoltaic panels; the clamping assembly is provided on the purlin and is used for clamping the photovoltaic panels.

[0009] By adopting this technical solution, during installation, one end of the fixing rod is passed through the wall, allowing the end of the stop block to press against the wall surface. The purlin is then mounted on the support plate, and the photovoltaic panel is placed on the purlin. Finally, the clamping assembly is used to press and secure the photovoltaic panel to the purlin, completing the installation. Because the fixing rod passes through the entire wall, the entire purlin installation is more secure, reducing the possibility of the photovoltaic bracket falling.

[0010] Preferably, the support plate includes a first plate, a second plate and a third plate that are integrally connected, the first plate and the second plate are connected, and an angle is formed between the two; the second plate and the third plate are connected, and an angle is formed between the two, and the second plate and the third plate are used to support the purlin; the fixing rod passes through the first plate, and a threaded portion is provided on the fixing rod, and the first plate is locked to the fixing rod by a nut.

[0011] By adopting the above technical solution, one end of the fixing rod passes through the first plate, the first plate is in contact with the wall, and then a nut is screwed onto the threaded portion to lock the first plate onto the fixing rod.

[0012] Preferably, a slot is provided on the purlin, and an end of the second plate away from the first plate is snapped into the slot.

[0013] By adopting the above technical solution, the second plate can be clamped in the clamping groove, further improving the connection stability between the purlin and the support plate.

[0015] By adopting the above technical solution, the fixing block is installed in the groove of the purlin, and the stud passes through the third plate, and then the nut is screwed on the stud, thereby realizing the connection between the purlin and the support plate.

[0016] Preferably, the clamping assembly includes an edge clamping block and a fastening bolt, wherein the edge clamping block is used to clamp the edge of the photovoltaic panel, and the fastening bolt passes through the edge clamping block and is used to lock the edge clamping block to the purlin.

[0017] By adopting the above technical solution, after the photovoltaic panel is placed on the purlin, the edge pressure block is pressed against the edge of the photovoltaic panel, and then the edge pressure block is locked to the purlin with the fastening bolts to complete the fixation of the photovoltaic panel.

[0018] Preferably, a plurality of friction lines are provided on the supporting surface of the purlin.

[0019] By adopting the above technical solution, the friction lines can increase the roughness of the purlin support surface, increase the contact static friction, and thus improve the stability of the photovoltaic panel installed on the purlin.

[0040] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples shown in the present application.

[0041] The embodiment of the present application discloses a photovoltaic bracket for solar panels. Figures 1 to 3 The photovoltaic bracket includes a fixing rod 1, a limit block 2, a support plate 3, a purlin 4 and a clamping assembly 5. The cross-section of the fixing rod 1 is circular, and the limit block 2 is fixedly connected to one end of the fixing rod 1. The cross-sectional area of the limit block 2 is larger than the cross-sectional area of the fixing rod 1. The end of the fixing rod 1 away from the limit block 2 passes through the wall, and the limit block 2 is used to abut against the wall surface of the wall. The support plate 3 is installed on the end of the fixing rod 1 away from the limit block 2, and the purlin 4 is detachably connected to the support plate 3. The purlin 4 is used for laying and supporting photovoltaic panels. The clamping assembly 5 is installed on the purlin 4 and is used to press the photovoltaic panel onto the purlin 4.

[0042] Combine Figure 4 and Figure 5 During installation, insert one end of the fixing rod 1 through the wall, allowing the end of the stopper 2 to press against the wall surface. Next, install the purlin 4 on the support plate 3, then lay the photovoltaic panel on top of the purlin 4. Finally, use the clamping assembly 5 to press and secure the photovoltaic panel to the purlin 4, completing the installation. Because the fixing rod 1 passes through the entire wall, the entire purlin 4 is installed more securely, reducing the possibility of the photovoltaic bracket falling.

[0043] Specifically, refer to Figure 3 The support plate 3 includes an integrally connected first plate 31, a second plate 32, and a third plate 33. The first plate 31 and the second plate 32 are connected to form an angle therebetween, which is a right angle. The second plate 32 and the third plate 33 are connected to form a 90-degree angle therebetween, and the second and third plates 32 and 33 jointly support the purlin 4. The fixing rod 1 is provided with a threaded portion. The end of the fixing rod 1 away from the stop block 2 passes through the first plate 31. The first plate 31 is locked to the fixing rod 1 with a nut.

[0044] The purlin 4 also has a slot 6 formed on one of its long sides, into which the end of the second plate 32 facing away from the first plate 31 is snapped. In this embodiment, the purlin 4 is mounted to the support plate 3 via a fixing block 7 and a stud 8. The purlin 4 has a groove 9 formed along its length, into which the fixing block 7 is mounted. One end of the stud 8 is fixedly connected to the fixing block 7, and the other end passes through the third plate 33, where it is locked to the third plate 33 with a nut.

[0045] To secure support plate 3 to the wall, first insert one end of fixing rod 1 through the wall and first plate 31, ensuring that first plate 31 is in close contact with the wall. Then, screw a nut onto the threaded portion to secure first plate 31 to fixing rod 1. Next, adjust the position of purlin 4 so that second plate 32 fits within slot 6. Finally, adjust the position of fixing block 7 within groove 9 of purlin 4, pass stud 8 through third plate 33, and screw a nut onto stud 8 to secure purlin 4 to support plate 3.

[0046] The clamping assembly 5 includes an edge clamp 51 and a fastening bolt 52. The edge clamp 51 is installed on the purlin 4 and is used to clamp the edge of the photovoltaic panel; the fastening bolt 52 passes through the edge clamp 51 and is used to lock the edge clamp 51 on the purlin 4. After the photovoltaic panel is placed on the purlin 4, the edge clamp 51 is used to clamp the edge of the photovoltaic panel, and then the fastening bolt 52 is used to lock the edge clamp 51 on the purlin 4 to complete the fixation of the photovoltaic panel. In some embodiments, a plurality of friction lines 10 are provided on the supporting surface of the purlin 4. The friction lines 10 can increase the roughness of the supporting surface of the purlin 4, increase the static friction between the photovoltaic panel and the purlin 4, and thus improve the stability of the photovoltaic panel installed on the purlin 4.

[0047] In some embodiments, please refer to Figure 2 , a positioner 12 is also installed on the purlin 4. The positioner 12 is locked to the purlin 4 by bolts. The positioner 12 is close to the clamping assembly 5. The positioner 12 is used to hang the photovoltaic panel. Since the wall is perpendicular to the ground, the installation position of the photovoltaic panel will be higher. By adding the positioner 12, the photovoltaic panel can be hung on the positioner 12 before being fixed, and then the edge of the photovoltaic panel can be pressed by the clamping assembly 5. The positioner 12 can assist in the installation of the photovoltaic panel and improve the safety of the production operation. If there is no positioner 12, at least two workers are required to carry the photovoltaic panel, and the wall to be installed is a high-altitude operation, which can easily lead to inconvenience in installation and pose a safety risk.

[0048] In addition, refer to Figure 3 , a material-saving cavity 11 is also provided on the purlin 4, and the material-saving cavity 11 is arranged along the length direction of the purlin 4. The material-saving cavity 11 can reduce the material consumption of the purlin 4 and reduce the manufacturing cost; at the same time, it can also reduce the weight of the purlin 4, making it easier to move and transport the purlin 4. In this embodiment, the purlin 4 is made of metal materials such as stainless steel or aluminum alloy, and a protective layer is also coated on the outer surface of the purlin 4. The protective layer can be but not limited to a metal layer, a non-metallic layer and a chemical layer. The protective layer can protect the appearance of the purlin 4, reduce the corrosion of the purlin 4, and extend the service life.

[0049] The implementation principle of a photovoltaic bracket for solar panels in an embodiment of the present application is: during installation, one end of the fixing rod 1 is first passed through the wall and the first plate 31 in sequence, so that the first plate 31 is in contact with the wall; then a nut is screwed onto the threaded portion to lock the support plate 3 on the fixing rod 1.

[0050] Next, adjust the position of the purlin 4 so that the second plate 32 can be snapped into the slot 6. Then adjust the position of the fixing block 7 in the groove 9 of the purlin 4, and let the stud 8 pass through the third plate 33. Use a nut to screw on the stud 8 to achieve the connection between the purlin 4 and the support plate 3.

[0051] Finally, the photovoltaic panel is laid on the purlin 4, and the photovoltaic panel is pressed and fixed to the purlin 4 using the pressing assembly 5 to complete the installation of the photovoltaic panel. Since the fixing rod 1 passes through the entire wall, the installation of the entire purlin 4 is more secure, reducing the possibility of the photovoltaic bracket falling.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
