Description

Technical Field

[0001] The utility model relates to the field of photovoltaic equipment, in particular to a connection component and a BIPV bracket. Background Art

[0002] Photovoltaic building integration (BIPV) is usually composed of purlins, gutters, support components and photovoltaic panels. The installation process is generally to fix the gutters on the roof purlins at a preset spacing, set multiple support components on the gutters, lay the photovoltaic panels on the support components, and fix them with pressing blocks. However, the installation of BIPV arrays is often affected by roof engineering errors, resulting in the installation spacing of the gutters being inconsistent with the preset, which in turn affects the installation of photovoltaic panels. In the existing technical solutions, after the photovoltaic panels are laid, the holes of the pressing blocks need to be aligned with the threaded holes on the support components, and then locked with fasteners. If there is a large error in the spacing of the gutters, or the photovoltaic components are not laid tightly enough, the holes of the pressing blocks cannot be aligned with the threaded holes. In this case, it is necessary to remove and reinstall the gutters, or adjust the fixed and installed parts, which is very inconvenient.

[0003] The traditional solution has the following shortcomings: First, since the holes of the rivet nuts of the component supports need to be aligned with the holes of the component blocks and then locked with fasteners, the construction has a low fault tolerance rate; second, on-site dismantling or re-drilling will consume a lot of manpower and material resources and extend the construction time. At the same time, there are difficulties in quality control and may also damage the strength and life of the roof purlins; finally, the existing support component design lacks sufficient strength and stability, especially when facing severe weather conditions such as strong winds and thick snow, which leads to limited load-bearing capacity and durability of the entire system. Utility Model Content

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose a connection assembly and a BIPV bracket, adopting the following technical solutions:

[0005] The utility model provides a connection component, including a support base, an embedded part and a bolt, the support base is provided with a mounting hole, the embedded part is provided with a screw hole, the lower end of the bolt is fixedly connected to the screw hole after passing through the mounting hole, the embedded part is provided with an elastic buckle, the elastic buckle can be slidably connected to the mounting hole left and right, and the screw hole is exposed in the mounting hole.

[0006] As a further improvement, it also includes a pressing block, which is provided with a through hole. The bolt passes through the through hole and the mounting hole in sequence and is threadedly connected to the screw hole.

[0007] As a further improvement, the support base comprises a connecting plate provided with the mounting hole, and connecting ears are fixedly provided on both left and right sides of the connecting plate.

[0008] As a further improvement, the above-mentioned mounting hole is a strip-shaped hole extending leftward and rightward.

[0009] As a further improvement, the elastic buckle comprises two clamping joints symmetrically arranged on the embedded part, and the screw hole is located between the two clamping joints.

[0010] As a further improvement, a plurality of first reinforcing ribs are provided at the connection between the connecting plate and the connecting ear, and a plurality of second reinforcing ribs are provided around the mounting hole of the connecting plate.

[0011] As a further improvement, both the front and rear sides of the connecting plate are provided with folded edges.

[0012] The utility model further provides a BIPV bracket, comprising any of the above-mentioned connecting components.

[0013] As a further improvement, it also includes a main water tank, the supporting base of the above-mentioned connecting component is fixedly connected across the top of the above-mentioned main water tank, and the lower end surface of the above-mentioned photovoltaic panel abuts against the upper end surface of the above-mentioned main water tank, and the pressing block of the above-mentioned connecting component abuts against the upper end surface of the photovoltaic panel.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] First, the utility model provides mounting holes and slidable embedded parts on the support base, so that the width of the fixed photovoltaic panel can be adjusted to a certain extent during the installation of the photovoltaic panel, thereby adapting to the engineering errors that may exist between the roof purlin and the main water tank. This structure improves the flexibility and fault tolerance of the installation, making the installation under different conditions and environments more convenient and effective.

[0016] Secondly, in the present invention, two elastic buckles are arranged on the upper end surface of the embedded part. When installing, the embedded part is pre-installed by snapping the elastic buckles to the inner side of the strip-shaped installation hole. This structure makes it easier to adjust the position of the embedded part when the photovoltaic panel is installed and fixed, and simplifies the installation process and reduces the installation time.

[0017] Thirdly, in the present invention, the connection between the connecting plate and the connecting ear of the supporting base is provided with reinforcing ribs to improve the structural strength and stability of the entire connecting assembly, so that the bracket can better withstand the loads brought by the photovoltaic panels and environmental factors (such as strong winds and thick snow). In addition, the folding design on the front and rear sides of the connecting plate further enhances the overall stability and durability of the connecting assembly.

[0018] Fourthly, the utility model can be flexibly installed above the main water tank, allowing installation on roof structures of different types and sizes.

[0032] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0033] In the description of the present invention, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. The terms "upper", "lower", "side", "end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0034] like Figure 1-Figure 3 As shown, a connection assembly provided by the utility model includes a support base 1, an embedded part 2 and a bolt 3, the support base 1 is provided with a mounting hole 11, the embedded part 2 is provided with a screw hole 21, the lower end of the bolt 3 is fixedly connected to the above-mentioned screw hole 21 after passing through the mounting hole 11; the embedded part 2 is provided with an elastic buckle 22, the elastic buckle 22 can be slidably connected to the mounting hole 11 left and right, and the screw hole 21 is exposed in the mounting hole 11.

[0035] In a specific embodiment, referring to Figure 4 and Figure 5 The support base 1 is installed on the main water tank 600, and the embedded part 2 is clamped into the mounting hole 11 from the bottom of the support base 1, and slides in the radial direction of the bolt 3 in the mounting hole 11. During installation, the photovoltaic panel 700 is laid on the support base 1, and then the photovoltaic panel 700 is clamped by the pressing block 4. Obviously, the pre-installation of the embedded part 2 can be realized through this structure, and the position of the embedded part 2 can be adjusted by sliding, and the width of the fixed photovoltaic panel 700 can be adjusted to a certain extent, which simplifies the installation process and reduces the installation time.

[0036] like Figure 1-Figure 3 As shown, it further includes a pressing block 4, on which a through hole 41 is provided. The bolt 3 passes through the through hole 41 and the mounting hole 11 in sequence and is threadedly connected to the above-mentioned screw hole 21.

[0037] In a specific embodiment, the above-mentioned pressure block 4 is a bilateral pressure block 4, and its left and right sides are extended to form an abutment portion 42, and the abutment portion 42 is provided with a strip groove 421 to enhance the friction of the abutment surface. The bolt 3 is sequentially sleeved with a flat washer 44 and a spring washer 43 between the upper end surface of the pressure block 4 and the bolt cap 31. The flat washer 44 provides a flat and stable surface to help disperse the pressure between the bolt cap 31 and the pressure block 4, and the spring washer 43 provides a continuous tightening force to prevent the bolt 3 from loosening due to factors such as vibration.

[0038] like Figure 1 and Figure 2As shown, the mounting hole 11 is a strip hole extending left and right, the elastic clip 22 is integrally formed with the embedded part 2, the elastic clip 22 is specifically two symmetrically arranged clip joints, the bolt 3 hole is arranged between the two clip joints, and the distance between the two clip joints matches the front and rear width of the strip hole.

[0039] In a specific embodiment, the mounting hole 11 is arranged in the middle of the connecting plate 1a, and its length direction is the connecting direction of the two connecting ears 1c. The embedded part 2 is slidably connected to the mounting hole 11 through a clamping joint. By sliding and changing the position of the embedded part 2, the width of the fixed photovoltaic panel 700 is adjusted to a certain extent. Through this structure, during the installation process of the photovoltaic panel 700, the engineering error that may exist between the purlin 500 and the main water tank 600 is adapted, which greatly reduces the strict requirements on the accuracy of construction and construction materials, improves the flexibility and fault tolerance of installation, and makes the installation work more convenient and effective.

[0040] like Figure 1 and Figure 2 As shown, the support base 1 includes a connecting plate 1a with a mounting hole 11, and connecting ears 1c are fixed on the left and right sides of the connecting plate 1a. The connecting plate 1a and the connecting ears 1c are connected by a ramp structure 1b, and the connecting plate 1a, the ramp structure 1b and the connecting ears 1c are integrally formed.

[0041] In a specific embodiment, the left and right sides of the support base 1 extend and bend upward and downward respectively to form a slope structure 1b, and the outer side of the slope structure 1b is bent downward to form a connecting ear 1c, and the connecting ear 1c further includes a horizontal support part and a bent connecting part. More specifically, one side of the support base 1 is bent upward by 30°, extended for a distance and then bent downward by 30° to form a Z-shaped structure with a negative angle of 150°, and the outer side of the second bending part is extended for a distance and then bent downward by 30°, and the other side of the support base 1 is set in the same way. In this way, the middle horizontal part of the support base 1 forms the above-mentioned connecting plate 1a, and the two sides are connecting ears 1c. The connecting plate 1a and the connecting ears 1c are connected by the slope structure 1b, and the horizontal plane height of the connecting plate 1a is lower than the horizontal plane height of the connecting ears 1c on both sides. When the connecting assembly is affected by frontal pressure, vibration or lifting force, the Z-shaped structure on both sides will undergo a certain deformation and return to the original state, which can effectively absorb and release energy. The slope structure 1b provides a smooth transition, reduces stress concentration, and helps to extend the service life of the entire structure.

[0042] like Figure 1-Figure 3 As shown, a plurality of first reinforcing ribs 12 are provided at the connection between the connecting plate 1a and the connecting ear 1c. In a specific embodiment, the first reinforcing ribs 12 are respectively provided at the bends between the slope structure 1b and the connecting plate 1a and the connecting ear 1c; Figure 1 and Figure 2 As shown, the connecting plate 1a is provided with a plurality of second reinforcing ribs 13 around the mounting hole 11. More specifically, the second reinforcing ribs 13 are integrally formed metal convex strips, which are provided on the front and rear sides of the strip hole and are parallel to the long side direction of the strip hole.

[0043] The connection components provided by the utility model are mostly used on roofs, balconies or open spaces, and often need to face harsh environmental conditions such as strong winds and snow. For example, strong winds can cause the connection components to vibrate. By setting reinforcing ribs, the structural strength of the bending part and the bending resistance of the connecting plate 1a are improved, and the stress generated by wind force, pressure or other effects is evenly distributed to prevent the connection components or their components from bending or breaking.

[0044] Furthermore, Figure 1 and Figure 2 As shown, the front and rear sides of the connecting plate 1a are extended and bent downward to form a folded edge 14, which further enhances the overall strength of the connecting plate 1a. At the same time, the processing of the folded edge 14 is simple, and the sharp edge of the plate is eliminated. When installing, the folded edge 14 on the front and rear sides of the connecting plate 1a can be held to better operate and avoid scratching the palm.

[0045] The utility model further provides a BIPV bracket including the above-mentioned connection assembly. Figure 4 As shown, the BIPV bracket is composed of purlins 500, main water tanks 600 and other components. Usually, the purlins 500 are evenly arranged between the roof trusses in a horizontal direction and fixed by welding or connecting pieces, and the main water tanks 600 are arranged perpendicular to the purlins 500. In a specific embodiment, a plurality of main water tanks 600 are arranged at intervals and fixedly connected to the upper end surface of the purlins 500 by bolts 3. The interval between two adjacent main water tanks 600 matches the left and right widths of the photovoltaic panels 700, and ensures that there is a certain drainage gap between each photovoltaic panel 700.

[0046] like Figure 5 As shown, the longitudinal section of the main water tank 600 is M-shaped, and the upper end surface of the M-shaped main water tank 600 is flat, which is used to abut against the photovoltaic panel 700. A plurality of connecting components are arranged in an array at the upper end of the main water tank 600, and the connecting ears 1c on both sides of the support base 1 are fixedly connected to the two sides of the main water tank 600 by bolts 3. Figure 4 As shown, the photovoltaic panel 700 is laid on the main water tank 600, and the pressing block 4 abuts against the upper end surface of the photovoltaic panel 700 and is locked and fixed by bolts 3. In particular, the pressing blocks 4 on the leftmost and rightmost connection components can be set as single-sided pressing blocks 4 (not specifically shown in the figure), that is, the pressing block 4 is only provided with the abutting portion 42 on one side.

[0047] like Figure 4As shown, a plurality of auxiliary water tanks 800 are disposed laterally at the upper end of the main water tank 600 to further improve drainage efficiency, reduce overflow risks, and prevent accumulated water from contacting and corroding the bracket and photovoltaic panel 700 for a long time.

[0048] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
