Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket technology, specifically to a quick-installation mechanism for crossbeams and frames that does not require drilling. Background Technology

[0002] In photovoltaic (PV) power generation systems, PV modules need to be mounted and fixed to supporting beams via their aluminum frames to form the entire PV array. Traditional installation methods typically require pre-drilling holes in the beams and then securing them with bolts through the holes in the frames and beams, or using separate clamping blocks and bolt combinations to clamp the frames to the beams. These traditional installation methods have the following disadvantages: The process is cumbersome and inefficient: it requires precise positioning and drilling on the crossbeam, which increases the number of production and on-site installation steps and time. Structural strength reduction: Drilling holes in the beam will damage its structural integrity, reduce the beam's load-bearing capacity and wind pressure resistance, especially in thin-walled profiles; High positioning accuracy is required: the holes on the crossbeam must correspond precisely to the positions of the frame, otherwise it will lead to installation difficulties or make installation impossible. Poor installation flexibility: Once drilling is completed, the position of the frame on the crossbeam is difficult to adjust, making it unable to meet the fine-tuning needs during on-site installation.

[0003] Therefore, there is an urgent need for an installation mechanism that requires no drilling into the crossbeam, is quick to install, has a reliable connection, and allows for position adjustment. Utility Model Content

[0004] The purpose of this utility model is to provide a quick installation mechanism for the crossbeam and frame without drilling, which solves the above problems, realizes a quick and reliable connection between the photovoltaic module frame and the crossbeam, and does not require pre-drilling holes in the crossbeam, thus maintaining the structural integrity of the crossbeam and allowing for position adjustment during installation.

[0005] Technical Solution: This utility model provides a quick-installation mechanism for a crossbeam and frame without drilling, comprising: a photovoltaic module frame, a crossbeam, and a connector; the crossbeam is positioned below the photovoltaic module frame, and the two are perpendicularly intersecting; the connector has a U-shaped structure, with one side of the upper part punched and bent inward to form a boss, and a notch forming a sliding part for the C-side of the frame, and a bolt hole is provided in the middle of the bottom of the connector; the connector is fitted onto the outside of the crossbeam and slides in along the crossbeam, the bottom surface of the photovoltaic module frame (i.e., the C-side in industry terminology) enters the sliding part for the C-side of the frame, the boss presses down and fastens the C-side of the photovoltaic module frame, and a fixing bolt is screwed into the bolt hole, the fixing bolt is continuously screwed in and pressed against the bottom surface of the crossbeam, fixing the photovoltaic module frame, the crossbeam, and the connector.

[0006] Furthermore, in the aforementioned quick-installation mechanism for beams and frames that requires no drilling, the beam can be selected from various conventional forms such as U-shaped beams, C-shaped beams, and square tube beams, and the connecting parts are all compatible.

[0007] Furthermore, in the aforementioned quick-installation mechanism for beams and frames that requires no drilling, the width of the sliding part of the frame C-side is equal to the extension length of the photovoltaic module frame C-side, to ensure that the frame can slide in smoothly and be precisely positioned.

[0008] Furthermore, in the aforementioned quick-installation mechanism for beams and frames that requires no drilling, the connector is placed close to the bottom surface of the beam during installation and adjustment. At this time, the boss is positioned higher than the C-side of the photovoltaic module frame. When fixing, it is pulled down, and the boss fastens to the C-side of the photovoltaic module frame.

[0009] Furthermore, in the aforementioned quick-installation mechanism for beams and frames that requires no drilling, the bolt holes are formed by punching and flanging the bottom of the connector, and the inside of the flanged holes is tapped, which increases the engagement length of the threads and improves the connection strength.

[0010] Furthermore, in the aforementioned quick-installation mechanism for beams and frames that requires no drilling, the length of the fixing bolt is greater than the depth of the bolt hole, to ensure that the end of the bolt can reliably abut against the bottom surface of the beam and generate sufficient preload.

[0011] Furthermore, in the aforementioned quick-installation mechanism for beams and frames that requires no drilling, spring washers and gaskets are sequentially installed between the fixing bolts and the connecting parts from the outside to the inside. The spring washers effectively prevent the bolts from loosening due to vibration, while the gaskets distribute pressure and protect the workpiece surface.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: The quick installation mechanism for the crossbeam and frame without drilling described in this utility model completely avoids drilling holes in the crossbeam, maintaining the structural strength and integrity of the crossbeam, and improving the load-bearing capacity and reliability of the entire support system; the connector can slide along the crossbeam, and the frame can slide directly in, and fixation can be completed by tightening a single bolt, greatly simplifying the installation process and improving installation efficiency; before final tightening, the connector and frame can slide arbitrarily on the crossbeam, facilitating on-site adjustment of the photovoltaic module installation position, with high fault tolerance and strong adaptability; through the dual action of the boss pressing down on the C-side of the frame and the bolt pressing against the bottom surface of the crossbeam, stable and reliable clamping and fixing are achieved, with good tensile and shear resistance; it is compatible with crossbeams of various cross-sectional forms, has a wide range of applications, and reduces production and inventory costs; the use of punched and bent connectors and standard fastening parts makes the manufacturing process simple and low-cost.

[0015] Example

[0016] like Figure 1-5 The diagram illustrates a quick-installation mechanism for a crossbeam and frame that requires no drilling. It includes a photovoltaic module frame 1, a crossbeam 2, and a connector 3. The crossbeam 2 is positioned below the photovoltaic module frame 1, with the two perpendicularly intersecting. The crossbeam 2 can be of various conventional forms, such as a U-shaped beam, a C-shaped beam, or a square tube beam, and the connector 3 is compatible with all of them. The connector 3 has a U-shaped structure, with one side of the upper part punched and bent inward to form a boss 31, and a notch forming a sliding part 32 on the C-side of the frame. A bolt hole 33 is located in the middle of the bottom of the connector 3. The connector 3 is fitted onto the outside of the crossbeam 2 and slides along the crossbeam 2. The bottom surface (i.e., the C-side) of the photovoltaic module frame 1 enters the sliding part 32 on the C-side of the frame. The boss 31 presses down to fasten the C-side of the photovoltaic module frame 1. A fixing bolt 34 is screwed into the bolt hole 33, and the fixing bolt 34 is continuously screwed in to press against the bottom surface of the crossbeam 2, thus fixing the photovoltaic module frame 1, the crossbeam 2, and the connector 3.

[0017] like Figure 5 The diagram shows a quick-installation mechanism for a beam and frame that requires no drilling. The width of the sliding part 32 on the C-side of the frame is equal to the extension length of the C-side of the photovoltaic module frame 1.

[0018] In this embodiment, during installation, the connector 3 is inserted from the end of the crossbeam 2. When adjusting the position, the connector 3 is pressed tightly against the bottom surface of the crossbeam 2. At this time, the boss 31 is higher than the C-side of the photovoltaic module frame 1, which facilitates position adjustment. When it is fixed, it is pulled down and tightened, and the boss 31 is fastened to the C-side of the photovoltaic module frame 1. The fixing bolt 34 is tightened with a tool. As the bolt is screwed in, its end will press against the bottom surface of the crossbeam 2. According to the principle of action and reaction, the boss 31 forms a downward pressure on the photovoltaic module frame 1 and the crossbeam 2. Through the downward pressure of the boss 31 and the tightening force of the fixing bolt 34, the photovoltaic module frame 1, the crossbeam 2 and the connector 3 are firmly locked together to form a stable whole.

[0019] like Figure 4 The diagram shows a quick-installation mechanism for a crossbeam and frame that does not require drilling. The bolt hole 33 is formed by punching and flanging the bottom of the connector 3, and the inside of the flanged hole is tapped. The length of the fixing bolt 34 is greater than the depth of the bolt hole 33.

[0020] In this embodiment, when the fixing bolt 34 is installed, a spring washer 341 and a gasket 342 are arranged between the bolt and the connector 3 from the outside to the inside. The spring washer 341 can effectively prevent the fixing bolt 34 from loosening due to vibration, while the gasket 342 can distribute pressure and protect the surface of the connector 3.

[0021] It should be noted that the above description is merely a technical solution of the utility model and not a limitation. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the utility model without departing from the scope of the present utility model, and all such modifications and substitutions should be covered within the scope of the claims of the present utility model.
