[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The utility model provides a U-shaped water tank fixing component, such as Figures 1 to 8 As shown, it includes a cross arm 1, a pressing piece 2 and a fastener. The cross arm 1 includes a supporting portion 11 and a fixing portion 12 located at both ends of the supporting portion 11, and the pressing piece 2 includes a clamping end 21 and a fixing end 22. During assembly, the fixing portion 12 of the cross arm 1 is mounted on the groove edge on both sides of the U-shaped gutter 4, and the supporting portion 11 of the cross arm 1 is used to support the photovoltaic module 5. The fixing portion 12 on each side of the cross arm 1 cooperates with a pressing piece 2, and the clamping end 21 of the pressing piece 2 is clamped with the photovoltaic module 5. The fixed end 22 of the pressing piece 2 corresponds to the fixing portion 12 of the cross arm 1, and the above structure is locked by fasteners to fix the connection between the U-shaped gutter 4 and the photovoltaic module 5.

[0035] The cross arm 1 is designed to be a bilaterally symmetrical structure, which can also ensure that the cross arm 1 can evenly distribute force when bearing a load, thereby improving its bearing capacity and service life.

[0036] like Figure 1 and Figure 2 As shown, the support portion 11 of the cross arm 1 is used to support the photovoltaic module 5. A supporting plane 111 is designed on the support portion 11, and the main function of this supporting plane 111 is to carry and hold up the photovoltaic module 5. In the middle of the supporting plane 111, a limiting protrusion 112 is specially provided. The function of this limiting protrusion 112 is to accurately locate the position of the photovoltaic module 5 when placing the photovoltaic module 5 and ensure its stable placement. At the same time, this limiting protrusion 112 also has a special function, that is, to place a puncture gasket to achieve the effect of puncturing the oxide layer on the surface of the frame of the photovoltaic module 5. By puncturing the oxide layer, good contact between the photovoltaic module 5 and the grounding system can be ensured, thereby facilitating grounding and conductivity, and improving the safety and reliability of the entire system.

[0037] like Figure 1 and Figure 2 As shown, a clamping groove 13 is formed between the support portion 11 and the fixing portion 12 of the cross arm 1, and the clamping groove 13 penetrates the support portion 11 along its own axial direction. The clamping end 21 of the pressing piece 2 cooperates with the clamping groove 13 of the cross arm 1. Specifically, the clamping end 21 of the pressing piece 2 is in a Y-shaped fork shape, and the Y-shaped fork includes a first fork 211 and a second fork 212. The first fork 211 is pressed against the upper end surface of the support portion 11 of the cross arm 1, and the second fork 212 is embedded in the clamping groove 13 of the cross arm 1.

[0038] 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. The installation position of the cross arm 1 and the pressure piece 2 is specifically structured as follows: Figure 1 and Figure 2 As shown, the fixing portion 12 of the cross arm 1 is a horizontal mounting platform 121, and a first mounting hole 122 is formed on the horizontal mounting platform 121, and the axis of the first mounting hole 122 is perpendicular to the horizontal mounting platform 121. Figure 3 As shown, the fixed end 22 of the pressing piece 2 extends horizontally outward from its clamping end 21, and the upper end surface of the fixed end 22 is provided with a horizontal boss 221, and the horizontal boss 221 is provided with a second mounting hole 222, the axis of the second mounting hole 222 is perpendicular to the horizontal boss 221, and the second mounting hole 222 passes through the horizontal boss 221 along its own axial direction.

[0039] When assembling, Figure 4 As shown, the fixed end 22 of the pressing piece 2 is placed on the fixed portion 12 of the cross arm 1, the axes of the first mounting hole 122 and the second mounting hole 222 coincide, and the clamping end 21 of the pressing piece 2 is clamped and matched with the supporting portion 11 of the cross arm 1 to clamp the photovoltaic assembly 5. Subsequently, the fastener passes through the first mounting hole 122 and the second mounting hole 222 from bottom to top and is locked to fix the photovoltaic assembly 5, the pressing piece 2, the cross arm 1 and the U-shaped water tank 4. Compared with the traditional left-right locking method, this method of locking the fastener 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 fastener, the possibility of interference between the tool and the photovoltaic panel during the fastening process is avoided, thereby greatly reducing the risk of damaging the photovoltaic panel assembly.

[0040] In this embodiment, the first mounting hole 122 and the second mounting hole 222 are both threaded holes. Correspondingly, the fastener is a bolt 3, preferably a hexagon socket bolt 3, which has the advantages of compact structure, reliable connection, and not easy to loosen.

[0041] In order to improve the stability of the installation, the present application optimizes the connection between the cross arm 1 and the pressing piece 2. Specifically, Figure 1 , Figure 2 and Figure 5 As shown, the outer end of the horizontal mounting platform 121 of the cross arm 1 extends horizontally upward and outward to form a first slope 123. Figure 3 As shown, the outer end of the fixed end 22 of the pressing piece 2 is horizontally tilted upward to form a second slope 223, and the slope surfaces of the first slope 123 and the second slope 223 abut against each other. The range of the angle α between the first slope 123 and the horizontal plane is 90°<α<180°, and the range of the angle β between the second slope 223 and the horizontal plane is β=180°-α. The purpose of this design is to provide stable support and guidance for the pressing piece 2 during installation. The outer end of the pressing piece 2 has a second slope 223 that matches the first slope 123. When the bolt 3 begins to tighten upward, a downward pulling force is generated, and this pulling force is transmitted to the contact surface of the first slope 123 and the second slope 223 through the pressing piece 2. Due to the limiting effect of the first slope 123, the pressing piece 2 will move toward the middle along the slope, and at the same time, the second slope 223 of the pressing piece 2 is tightly squeezed with the first slope 123 of its contact surface. By using the mechanical principle of the slope, not only the stability and directionality of the pressing piece 2 during the locking process are ensured, but also the photovoltaic panel assembly frame is evenly and tightly pressed by mutual squeezing. This pressing 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.

[0042] The slope design also makes the installation of the components adjustable. The installer can tighten or loosen the bolts 3 according to actual needs and fine-tune the pressing piece 2 to ensure that the connection between the U-shaped water tank 4 and the cross arm 1 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.

[0043] Key References Figure 2 The lower end surface of the horizontal mounting platform 121 on each side of the cross arm 1 is designed with a limiting portion 124, and the limiting portion 124 is used to be firmly connected to the groove edge of the U-shaped water tank 4. The first mounting hole 122 passes through the limiting portion 124 and is used to fix or connect other components. When the horizontal mounting platform 121 is set on the U-shaped water tank 4, its limiting portion 124 will naturally embed into the notch 41 of the groove edge of the U-shaped water tank 4, thereby forming a stable and non-slip connection structure. In this embodiment, the limiting portion 124 includes two convex ridges 1241 protruding from the lower surface of the horizontal mounting platform 121, and the two convex ridges 1241 are respectively located on both sides of the first mounting hole 122.

[0044] In order to increase the stability of the connection, the pressure piece 2 is designed to be non-slip. Figure 3As shown, the lower end surface of the fixed end 22 of the pressing piece 2 has anti-skid lines or anti-skid protrusions 224. When assembled and contacted with the cross arm 1, these structures can effectively prevent sliding during use.

[0045] In order to reduce the rigidity stress and reduce the overall weight, hollow grooves are provided at multiple locations on the cross arm 1. Figure 1 As shown, first, a first hollow groove 14 is provided in the middle of the support portion 11, and the number can be one or more, and the first hollow groove 14 penetrates the support portion 11 along its own axis direction. The cross-sectional shape of the first hollow groove 14 is not specifically limited in this application. In addition to the trapezoid shown in this embodiment, it can also be any shape such as a rectangle or a triangle, and the selection of these shapes mainly depends on the mechanical requirements and manufacturing process considerations in practical applications. Furthermore, a plurality of second hollow grooves 15 are designed at the connection between the support portion 11 and the fixing portion 12, and these second hollow grooves 15 also penetrate the support portion 11 along its own axis direction. In this embodiment, three second hollow grooves 15 are distributed at the connection between the fixing portion 12 and the support portion 11 on each side, and the cross-sections of these second hollow grooves 15 are all triangular. The triangular cross-sectional shape has excellent stability and can reduce the weight of the cross arm 1 to a certain extent. Of course, according to actual needs, the cross-sectional shape of the second hollow groove 15 can also be flexibly selected, such as a rectangle, a trapezoid, etc.

[0046] In addition, the side of the cross arm 1 in the conventional technology often needs to extend to an additional position as a mounting position, such as Figure 8 As shown, this will increase the consumption of materials. However, the utility model optimizes the structural design and integrates the installation position on the fixing part 12, without the need for additional extension materials, which not only ensures that the function of the cross arm 1 remains unchanged, but also saves more materials and reduces costs compared to other solutions. This design not only improves the cost performance of the product, but also helps promote the widespread application and development of photovoltaic building integration (BIPV) technology.

[0047] The method of using the U-shaped sink fixing assembly of the utility model is as follows (reference Figures 5 to 7 ):

[0048] First, place the cross arm 1 on the U-shaped water tank 4, with the support portion 11 of the cross arm 1 located in the U-shaped water tank 4. At the same time, the two fixing portions 12 of the cross arm 1 are respectively mounted on the two groove edges of the U-shaped water tank 4, and the position is adjusted so that the limiting portion 124 is embedded in the notch 41 of the U-shaped water tank 4.

[0049] Then, place the photovoltaic module 5 on the support portion 11 of the cross arm 1 and ensure that it is placed stably, and then continue to place the pressing piece 2, the second fork 212 of the pressing piece 2 is embedded in the clamping groove 13 of the cross arm 1, and the first fork 211 presses the frame of the photovoltaic module 5, and then adjust the second mounting hole 222 of the pressing piece 2 to align with the first mounting hole 122 of the cross arm 1 and the mounting hole of the U-shaped water tank 4;

[0050] Finally, the bolt 3 is locked from bottom to top. As the bolt 3 is tightened, the pressing piece 2 gradually moves inward, so that the Y-shaped fork on it gradually clamps the photovoltaic module 5 and the cross arm 1, and finally the whole assembly process is completed.
