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. Background Art

[0002] BIPV (Building Integrated Photovoltaic) is a form of distributed photovoltaic power generation system that combines photovoltaic power generation technology with architectural design. By seamlessly integrating photovoltaic power generation products into building structures, BIPV not only achieves the power generation function, but also retains the original properties of building materials, such as beauty and durability. It has a wide range of applications and can be used in a variety of building forms such as flat roofs, pitched roofs, curtain walls, ceilings, sun rooms, carports, etc.

[0003] When applying BIPV technology on building roofs, waterproofing and fastening photovoltaic modules are two crucial links. To ensure the waterproof effect, the traditional method usually sets a water guide groove under the gap between adjacent photovoltaic modules, and fixes the water guide groove to the photovoltaic module in some way to achieve rainwater collection and drainage. However, the existing photovoltaic module accessories have the following problems in practical applications:

[0004] When the photovoltaic module accessories are connected to the water guide groove, the installation process is complicated, time-consuming and labor-intensive. Moreover, 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 may also cause scratches, breakage and other unnecessary damages to the photovoltaic panel, thereby affecting the power generation efficiency and service life of the photovoltaic panel. Utility Model Content

[0005] The utility model aims to provide a U-shaped water tank cross arm to simplify the photovoltaic module installation process, improve the installation efficiency, and avoid interference with the photovoltaic module.

[0006] To achieve the above-mentioned purpose, the solution of the utility model is: a U-shaped water tank cross arm, comprising a supporting part and fixing parts located on both sides of the supporting part, wherein the fixing parts are mounted on the U-shaped water tank and used to connect the U-shaped water tank and the pressing block;

[0007] The fixing part has a horizontal mounting platform, a mounting hole is formed on the horizontal mounting platform, the axis of the mounting hole is perpendicular to the horizontal mounting platform, and the mounting hole is used to cooperate with a fastener to fix the pressing block to the cross arm.

[0008] Furthermore, the outer end of the horizontal mounting platform extends horizontally upward and outward in an inclined manner to form a slope, and the slope is used to provide support for the pressing block during installation.

[0009] Furthermore, the lower surface of the horizontal mounting platform has a limiting portion, and the mounting hole passes through the limiting portion. When the horizontal mounting platform is set up on the U-shaped water tank, the limiting portion is embedded in the notch of the groove edge of the U-shaped water tank.

[0010] Furthermore, the limiting portion includes two ridges protruding from the lower surface of the horizontal mounting platform, and the two ridges are located on both sides of the mounting hole.

[0011] Furthermore, a clamping groove for cooperating and fixing with the pressing block is provided at the connection between the supporting part and the fixing part, and the clamping groove penetrates the supporting part along its own axial direction.

[0012] The clamping groove opens at a chamfered angle from the groove opening to the groove bottom.

[0013] Furthermore, a first hollow groove is formed in the middle of the support portion, and the first hollow groove penetrates the support portion along its own axial direction.

[0014] Furthermore, a plurality of second hollow grooves are formed at the connection between the support portion and the fixing portion. The second hollow grooves penetrate the support portion along their own axial direction, and the cross-section of the second hollow grooves is triangular.

[0015] Furthermore, the support portion has a supporting plane, and a limiting protrusion is provided in the middle of the supporting plane.

[0016] Furthermore, the cross arm is a bilaterally symmetrical structure.

[0017] Furthermore, the fastener comprises a hexagon socket bolt.

[0018] After adopting the above scheme, the beneficial effects of the utility model are:

[0019] The utility model optimizes the installation process of photovoltaic modules by changing the installation position on the cross arm. Specifically, the design of the horizontal mounting platform on the fixed part and the mounting holes opened thereon enables the pressure block to be stably placed on the horizontal mounting platform, and the bolt locking operation is performed through the assembly holes that match the mounting holes. Compared with the traditional left-right locking method, this method of locking the bolts from bottom to top 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.

[0020] In addition, the side of the cross arm in traditional technology often needs to extend an extra position as a mounting position, which increases material consumption. However, the utility model optimizes the structural design and integrates the mounting position on the fixed part, without the need for additional extension materials, which not only ensures that the function of the cross arm remains unchanged, but also saves more materials and reduces costs compared to other solutions. This design not only improves the cost-effectiveness of the product, but also helps promote the widespread application and development of photovoltaic building integration (BIPV) technology.

[0031] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The utility model provides a U-shaped water tank cross arm 1, such as Figures 1 to 6As shown, it includes a support portion 11 and a fixing portion 12 located on both sides of the support portion 11, wherein the support portion 11 is used to support the photovoltaic module 5, and the fixing portion 12 is used to connect the U-shaped water tank 4 and the pressing block 2, and then through the cooperation of fasteners, the photovoltaic module 5 and the U-shaped water tank 4 are installed and fixed. The cross arm 1 is designed to be a left-right symmetrical structure, and the left-right symmetrical structure can also ensure that the cross arm 1 can evenly distribute the force when bearing a load, thereby improving its bearing capacity and service life.

[0033] like Figures 1 to 3 As shown, a supporting plane 111 is designed on the supporting portion 11 of the cross arm 1. 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.

[0034] 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 specific structure is as follows: Figures 1 to 3 As shown, the fixing part 12 has a horizontal mounting platform 121. A mounting hole 122 is provided on the horizontal mounting platform 121, and the axis of the mounting hole 122 is perpendicular to the horizontal mounting platform 121. The mounting hole 122 is 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.

[0035] The pressing block 2 is provided with a corresponding assembly hole 21 which matches the mounting hole 122. Figure 4 When assembling, place the pressing block 2 on the horizontal mounting platform 121, and then operate the locking bolt 3 from bottom to top, as shown in FIG. Figure 5 As shown. 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 tool and the photovoltaic panel during the tightening process is avoided, thereby greatly reducing the risk of damaging the photovoltaic panel assembly.

[0036] In order to improve the stability of installation, the present application proposes an optimized horizontal mounting platform 121 design. Specifically, the outer end of the horizontal mounting platform 121 extends horizontally upward and outward, forming a first slope 123. The purpose of this design is to provide stable support and guidance for the pressing block 2 during the installation process. The outer end of the pressing block 2 has a second slope 22 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 22 through the pressing block 2. Due to the limiting effect of the first slope 123, the pressing block 2 will move toward the middle along the slope, and at the same time, the second slope 22 of the pressing block 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 block 2 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.

[0037] As shown in the figure, the lower surface of each horizontal mounting platform 121 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 mounting hole 122 runs 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 ribs 1241 protruding from the lower surface of the horizontal mounting platform 121, and the two convex ribs 1241 are respectively located on both sides of the mounting hole 122.

[0038] In addition, in this design, the key reference Figure 1 The connection between the support part 11 and the fixing part 12 of the cross arm 1 is provided with a clamping groove 13 for fixing with the pressing block 2, and the clamping groove 13 penetrates the support part 11 along its own axis direction. Figure 4 The snap-in groove 13 can be used to cooperate with the pressing block 2 with a Y-shaped end to clamp the photovoltaic panel assembly, which can effectively prevent the photovoltaic panel assembly from being displaced or falling off during use. In this embodiment, in order to further improve the tightness and stability of the fit between the snap-in groove 13 and the pressing block 2, the snap-in groove 13 opens at a chamfered angle from the notch to the bottom of the groove. This design allows the pressing block 2 to enter the snap-in groove 13 more smoothly when inserted, and after being fully embedded, due to the presence of the chamfered angle, the pressing block 2 will be subjected to an inward extrusion force, thereby forming a tighter combination with the snap-in groove 13, ensuring the stable installation of the photovoltaic assembly 5.

[0039] In order to reduce the rigidity stress and reduce the overall weight, hollow grooves are provided at multiple locations on the cross arm 1. Figures 1 to 3As 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.

[0040] In addition, the existing cross arm structure often needs to extend the side of the additional position as the installation position, which increases the material consumption. However, the utility model optimizes the structural design and integrates the installation position on the fixed part, without the need for additional extension materials, which not only ensures that the function of the cross arm remains unchanged, but also saves more materials and reduces costs compared with other solutions.

[0041] The method of using the U-shaped water tank cross arm 1 of the utility model is as follows (reference Figure 5 and Figure 6 ):

[0042] 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.

[0043] Then, place the photovoltaic module 5 on the support portion 11 of the cross arm 1 and ensure that it is placed stably. Continue to place the pressing block 2. The first branch 23 of the Y-shaped front end of the pressing block 2 is embedded in the clamping groove 13 of the cross arm 1. The second branch 24 presses the frame of the photovoltaic module 5. Then adjust the assembly hole 21 at the rear end of the pressing block 2 to align with the mounting hole 122 of the cross arm 1 and the mounting hole 122 of the U-shaped water tank 4.

[0044] Finally, the bolt 3 is locked from bottom to top, completing the whole assembly process. Figure 5 shown.
