Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic assembly installation, in particular to a U-shaped water tank cross arm pressure piece. Background Art

[0002] With the increasing attention paid to renewable energy around the world, distributed photovoltaic power generation systems, especially building integrated photovoltaic (BIPV) technology, have become an important direction for the development of green buildings and sustainable energy. BIPV technology seamlessly integrates photovoltaic power generation products into building structures, which not only realizes the power generation function but also retains the original properties of building materials, such as beauty and durability, so it has been widely used.

[0003] When applying BIPV technology on building roofs, waterproofing and fastening of photovoltaic modules are two crucial links. The quality of waterproofing directly affects the service life of the building and the operating efficiency of the photovoltaic power generation system. Traditional waterproofing methods, such as setting up water guides under the gaps between adjacent photovoltaic modules, can collect and drain rainwater to a certain extent, but there are still many problems in practical applications.

[0004] First, when the photovoltaic module accessories are connected to the water channel, the installation process is complicated, time-consuming and labor-intensive, which not only increases the construction cost but also reduces the construction efficiency. Secondly, the bolt installation direction is parallel to the photovoltaic panel, and the installation position is close to the photovoltaic panel. When using tools to tighten the bolts, it is easy to interfere with the photovoltaic panel, which not only affects the installation efficiency, but also may cause scratches, breakage and other unnecessary damage to the photovoltaic panel, thereby affecting the power generation efficiency and service life of the photovoltaic panel. Utility Model Content

[0005] The purpose of the utility model is to provide a U-shaped water tank cross arm pressure piece, which has a simple structure and simplifies the installation process, improves the installation efficiency, and reduces potential damage to the photovoltaic panel when cooperating with the cross arm to fix the photovoltaic component and the waterproof component.

[0006] To achieve the above-mentioned purpose, the solution of the utility model is: a U-shaped water tank cross arm pressure piece, the pressure piece includes a clamping end and a fixed end, the clamping end is clamped with the cross arm to press the photovoltaic component; the fixed end extends horizontally outward from the clamping end, and the fixed end is provided with a mounting hole, and the axis of the mounting hole is perpendicular to the photovoltaic component.

[0007] Furthermore, the upper end surface of the fixed end is provided with a horizontal boss, the mounting hole is arranged on the horizontal boss, and the mounting hole passes through the horizontal boss along the axial direction thereof.

[0008] Furthermore, the mounting hole is a threaded hole.

[0009] Furthermore, the outer end of the fixed end has a horizontally upwardly inclined guide slope.

[0010] Furthermore, the included angle α between the guide slope and the horizontal plane is in the range of 0°<α<90°.

[0011] Furthermore, the clamping end is in a Y-shaped fork, and the Y-shaped fork includes a first fork and a second fork, the lower end face of the first fork abuts against the photovoltaic component, and the upper end face of the second fork abuts against the cross arm to press the photovoltaic component onto the cross arm.

[0012] Furthermore, the lower end surface of the fixed end has anti-skid lines or anti-skid protrusions.

[0013] After adopting the above scheme, the beneficial effects of the utility model are:

[0014] The utility model greatly optimizes the installation process of the waterproof structure of the photovoltaic module by changing the installation position on the pressing piece, which not only improves the work efficiency, but also significantly enhances the safety of the installation. Specifically, the pressing piece includes a clamping end and a fixed end, and the clamping end is clamped with the cross arm to compress the photovoltaic module; and the fixed end is formed by the clamping end extending horizontally outward, and the fixed end is provided with a mounting hole, and the axis of the mounting hole is perpendicular to the photovoltaic module. During the installation process, workers can operate by locking the bolts from bottom to top. Compared with the traditional left and right locking method, this method provides workers with a larger operating space, making the assembly process more convenient and efficient. At the same time, due to the vertical installation of the bolts, the possibility of interference between the tool and the photovoltaic panel during the tightening process is avoided, thereby greatly reducing the risk of damaging the photovoltaic panel assembly.

[0015] In addition, the slope structure of the fixed end of the pressing piece cooperates with the cross arm and the bolt locking piece, and utilizes the mechanical principle of the slope to not only ensure the stability and directionality of the pressing piece during the locking process, but also achieves uniform and tight compression of the frame of the photovoltaic panel assembly through mutual extrusion.

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] The utility model provides a U-shaped water tank 4 cross arm 2 pressing piece 1, which is usually used in conjunction with the cross arm 2 to fix the photovoltaic module 5. Figures 1 to 5 As shown, the pressing piece 1 includes a clamping end 11 and a fixed end 12. The cross arm 2 includes a clamping portion 21 and a fixed portion 22. The clamping end 11 of the pressing piece 1 cooperates with the clamping portion 21 of the cross arm 2 to clamp the photovoltaic module 5. The fixed end 12 of the pressing piece 1 extends horizontally outward from its clamping end 11. The fixed end 12 is provided with a mounting hole 122, and the axis of the mounting hole 122 is perpendicular to the photovoltaic module 5.

[0027] In this embodiment, the clamping end 11 of the pressing member 1 is in a Y-shaped fork shape, and the Y-shaped fork cooperates with the clamping portion 21 of the cross arm 2 to press the photovoltaic module 5. Specifically: Figure 1 As shown, the Y-shaped fork includes a first fork 111 and a second fork 112. The lower end face of the first fork 111 abuts against the photovoltaic module 5, and the upper end face of the second fork 112 abuts against the cross arm 2. Through the synergistic effect of the two forks, the photovoltaic module 5 and the cross arm 2 are tightly pressed together, thereby greatly reducing the risk of the photovoltaic module 5 falling off under severe weather conditions.

[0028] The key point of the utility model is to change the installation position of the assembly components, thereby significantly improving the installation efficiency and safety. Figure 1The fixed end 12 of the pressing piece 1 is formed by the clamping end 11 extending horizontally outward, and the upper end surface of the fixed end 12 is provided with a horizontal boss 121, and the mounting hole 122 is arranged on the horizontal boss 121, and the mounting hole 122 passes through the horizontal boss 121 along its axial direction, and the axis of the mounting hole 122 is specially designed to be perpendicular to the photovoltaic module 5, and the fixing part 22 of the cross arm 2 is also provided with an assembly hole 221 that matches the mounting hole 122 of the pressing piece 1. This design can easily and quickly install the pressing piece 1, the cross arm 2 and the photovoltaic module 5 by bolts 3 or other fixing methods.

[0029] In order to further enhance the reliability of the connection and the convenience of operation, the mounting hole 122 is designed as a threaded hole, and accordingly, a hexagon socket bolt 3 can be used as a fastener. The hexagon socket bolt 3 has the advantages of compact structure, reliable connection, and not easy to loosen. Figure 4 As shown. During assembly, the pressing piece 1 is placed on the fixing portion 22 of the cross arm 2, and then the bolt 3 is tightened from bottom to top. Compared with the traditional left-right tightening method, this method of tightening the bolt 3 from bottom to top provides a larger operating space, allowing workers to operate more conveniently. At the same time, due to the vertical installation of the bolt 3, the possibility of interference between the installation tool and the photovoltaic panel during the tightening process is avoided, thereby greatly reducing the risk of damaging the photovoltaic panel assembly.

[0030] To improve the stability of the installation, Figure 1 and 4 As shown, the outer end of the fixed end 12 of the pressing piece 1 has a first guide slope 123 that is horizontally inclined upward. The range of the angle α between the first guide slope 123 and the horizontal plane is 0°<α<90°, and the first guide slope 123 cooperates with the second guide slope 222 at the end of the mounting portion of the cross arm 2. When the bolt 3 begins to tighten upward, a downward pulling force will be generated, and this pulling force will be transmitted to the contact surface of the first guide slope 123 and the second guide slope 222 through the pressing piece 1. Due to the limiting effect of the second guide slope 222, the pressing piece 1 will move toward the middle along the slope, and at the same time, the first guide slope 123 of the pressing piece 1 is tightly squeezed with the second guide slope 222 of its contact surface. By utilizing the mechanical principle of the slope, not only the stability and directionality of the pressing piece 1 during the locking process are ensured, but also the uniform and tight compression of the frame of the photovoltaic panel assembly is achieved by mutual extrusion. This compression method not only improves the installation stability of the photovoltaic panel assembly, but also helps to reduce the risk of loosening or damage caused by factors such as vibration or wind.

[0031] The slope design makes the installation of the components adjustable. The installer can tighten or loosen the bolts 3 according to actual needs and fine-tune the pressure piece 1 to ensure that the connection between the U-shaped water tank 4 and the cross arm 2 is in the best state. This flexibility not only improves the accuracy of the installation, but also greatly simplifies the installation process, making the entire installation process more efficient and convenient.

[0032] In order to increase the stability of the connection, the pressure piece 1 is designed to be non-slip. Figure 1 and Figure 2 As shown, the lower end surface of the fixed end 12 has anti-skid lines or anti-skid protrusions 124. When assembled and contacted with the cross arm 2, these structures can effectively prevent sliding during use.

[0033] The pressing piece 1 of the present invention is preferably made of aluminum alloy. Aluminum alloy, with its light weight and high strength, can easily bear the weight of the photovoltaic module 5, ensuring the stability and safety of the structure. At the same time, aluminum alloy also has good corrosion resistance, and can be used for a long time even in a humid environment without being easily affected by corrosion, thereby greatly extending the service life of the pressing piece 1.

[0034] The method of using the pressing piece 1 of the utility model is as follows (reference Figure 4 and Figure 5 ):

[0035] First, place the cross arm 2 on the U-shaped water tank 4, and the two fixing parts 22 of the cross arm 2 are respectively mounted on the two groove edges of the U-shaped water tank 4. Then, place the photovoltaic module 5 on the cross arm 2 and ensure that it is placed stably. Continue to place the pressing piece 1. The second fork 112 of the clamping end 11 of the pressing piece 1 is embedded in the clamping groove of the cross arm 2. The first fork 111 presses the frame of the photovoltaic module 5. Then adjust the installation hole 122 of the fixed end 12 of the pressing piece 1 to align with the assembly hole 221 of the cross arm 2 and the assembly hole 221 of the U-shaped water tank 4. Finally, lock the bolt 3 from bottom to top, and complete the whole assembly process. After the assembly is completed, Figure 4 shown.
