Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a fastening structure for photovoltaic power generation. Background Technology

[0002] The mounting brackets for solar photovoltaic (PV) panels play a crucial role in supporting and securing the panels, adjusting their angle and orientation to maximize energy capture efficiency, and protecting them from external environmental influences. The brackets are typically connected to the mounting surface via bolts, screws, or a concrete foundation, and are made of weathering steel or aluminum, offering excellent corrosion resistance and strength. Since PV panels are installed in batches, adjacent brackets require a fastening structure for connection. This fastening structure, usually made of weathering steel or aluminum and matching the bracket's structural material, uses bolts, screws, or specially designed clamps to secure adjacent brackets together. However, this process involves separate fastening structures from the mounting brackets, requiring pre-drilling, adjusting connector positions, proper installation, and tightening. This necessitates certain technical skills and tools, creating difficulties for on-site installation. Furthermore, errors during installation can lead to weak or unstable connections, affecting the overall performance of the mounting system. Utility Model Content

[0003] The purpose of this utility model is to provide a fastening structure for photovoltaic power generation, which adds flat plates and right-angle support plates to the outer walls on both sides of the U-shaped bottom frame.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 An embodiment of this utility model provides a fastening structure for photovoltaic power generation, including a U-shaped bottom frame 1 and right-angle support plates 4 and flat plates 5 fixed on the outer walls of both sides of the U-shaped bottom frame 1. A bracket 2 is installed at the top of the U-shaped bottom frame 1, and a solar panel 3 is installed on one side of the outer wall of the bracket 2. A T-shaped anti-detachment structure is provided between the right-angle support plates 4 and the flat plates 5. F-shaped protrusions 7 are integrally formed at both ends of the surface of the flat plates 5. A first slot 701 and a second slot 702 are respectively provided on both sides inside the F-shaped protrusions 7. Rectangular protrusions 9 are installed at both ends of the right-angle support plates 4. The rectangular protrusions 9 and the second slot 702 are interlocked with each other. The rectangular protrusions 9 and the F-shaped protrusions 7 form an interlocking structure. Two symmetrical spring positioning pins 8 are installed on the inner wall of one side of the U-shaped bottom frame 1. The pin ends of the spring positioning pins 8 are interlocked with the F-shaped protrusions 7 and the rectangular protrusions 9.

[0019] The bottom corners of the spiral-shaped base frame 1 are provided with internal threaded holes 101, and the bottom end of the spiral-shaped base frame 1 is provided with an opening. The spiral-shaped base frame 1 is pre-fixed to the mounting surface by bolting.

[0020] The T-shaped anti-detachment structure consists of T-shaped cutting grooves 6 on both sides of the surface of the flat plate 5 and T-shaped inserts 10 integrally formed on both sides of the surface of the right-angle support plate 4. The T-shaped cutting grooves 6 and T-shaped inserts 10 are interlocked. When the right-angle support plate 4 and the flat plate 5 are connected in the vertical direction, the T-shaped cutting grooves 6 and T-shaped inserts 10 are interlocked to prevent the two adjacent loop-shaped bottom frames 1 from becoming loose in the horizontal direction.

[0021] The surfaces of the F-type protrusion seat 7 and the rectangular protrusion plate 9 are provided with concentric through holes. The outer diameter of the pin end of the spring positioning pin 8 is equal to the diameter of the through hole. When the right-angle support plate 4 and the flat plate 5 are connected, the rectangular protrusion plate 9 is located in the second slot 702. At this time, the through holes on the rectangular protrusion plate 9 and the F-type protrusion seat 7 are concentric, and the pin end of the spring positioning pin 8 can enter the through hole, thereby realizing the locking function of the rectangular protrusion plate 9 and the F-type protrusion seat 7, so that the two adjacent loop-shaped bottom frames 1 can be quickly connected.

[0022] The length of the flat plate 5 is equal to the width of the rectangular base frame 1. The rectangular base frame 1, the right-angle support plate 4, and the flat plate 5 are all made of aluminum alloy components. Using aluminum alloy components to manufacture the rectangular base frame 1, the right-angle support plate 4, and the flat plate 5 can effectively reduce the weight of the entire solar photovoltaic system.

[0023] In this embodiment, the operator first removes the two loop-shaped base frames 1 to be connected. One of the loop-shaped base frames 1 is pre-fixed to the mounting surface by bolts. Then, the bracket 2 and the solar panel 3 are installed sequentially on the top of the loop-shaped base frame 1. Next, the operator pulls the spring positioning pin 8, causing the pin end of the spring positioning pin 8 to retract into the first slot 701 and into the interior of the plate 5. Then, the right-angle support plate 4 on the outer wall of the other loop-shaped base frame 1 is connected to the plate 5 via a T-shaped anti-detachment structure. After the right-angle support plate 4 and the plate 5 between the opposite outer walls of the two loop-shaped base frames 1 are connected in place via the T-shaped anti-detachment structure, the rectangular protrusion 9 is located in the second slot 702. The operator then releases the spring positioning pin 8, causing the pin end of the spring positioning pin 8 to automatically... The spring positioning pin 8 and the rectangular protrusion 9 are inserted into the first slot 701, the F-shaped protrusion 7, and the rectangular protrusion 9. At this time, the insertion of the spring positioning pin 8 and the rectangular protrusion 9 prevents the right-angle support plate 4 and the flat plate 5 from separating in the vertical direction, while the T-shaped anti-detachment structure prevents the right-angle support plate 4 and the flat plate 5 from separating in the horizontal direction. This structural design makes the connection between two adjacent loop-shaped bottom frames 1 more secure and less prone to loosening or falling off, preventing the movement or shaking between the brackets and reducing the risk of the brackets loosening or falling off. Moreover, the connection method of using the T-shaped anti-detachment structure and the insertion structure can simplify the installation process. This connection method does not require complicated bolt tightening and adjustment. The connection can be completed simply by inserting the connecting parts, which reduces the time in the installation process and makes it convenient for workers to arrange and connect brackets in batches on site.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
