Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, and in particular to a connecting component for photovoltaic panel installation and a carbon steel bracket for BIPV. Background Technology

[0002] With the rapid development of new energy technologies, photovoltaic power generation systems are being used more and more widely, especially in the field of building-integrated photovoltaics (BIPV). The installation structure of photovoltaic modules not only needs to meet the requirements of a stable and reliable mechanical connection, but also needs to have excellent conductivity to ensure the safe operation of the system and extend the service life of the photovoltaic panels.

[0003] Existing photovoltaic (PV) panel installation structures typically use clamps and support bases secured with bolts. However, since PV panel support structures are usually made of metals such as aluminum alloys, an oxide film easily forms on their surface, leading to static electricity buildup and affecting the safety and overall performance of the PV equipment. Furthermore, current BIPV arrays often suffer from discrepancies between the installation and intended spacing of the main water tanks due to roof engineering errors, affecting the installation of PV modules. This often necessitates the removal and reinstallation of the water tanks or adjustments to already fixed installations, which is extremely inconvenient. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a connecting component for photovoltaic panel installation and a carbon steel bracket for BIPV, and the following technical solution is adopted:

[0005] This utility model provides a connection component for photovoltaic panel installation, including a support base, an embedded part, a pressure block, and a bolt. The support base is provided with a clearance hole. The lower end of the bolt passes through the pressure block and the clearance hole in sequence and is threaded to the embedded part. The component also includes a conductive sheet with a mounting hole. The elastic buckle of the embedded part passes through the clearance hole and engages with the front and rear edges of the mounting hole.

[0006] As a further improvement, the photovoltaic panel is sandwiched between the conductive sheet and the pressure block, and the conductive sheet is provided with a plurality of puncture portions for piercing the oxide film on the surface of the photovoltaic panel.

[0007] As a further improvement, the upper surface of the conductive sheet is provided with several annular protrusions to form the aforementioned puncture portion.

[0008] As a further improvement, the support base is provided with a second reinforcing rib around the clearance hole, and the annular protrusion is located above the second reinforcing rib.

[0009] As a further improvement, the conductive sheet is provided with ear plates on both the front and rear sides of the mounting hole, and the elastic buckle is engaged with the upper ends of the two ear plates.

[0010] As a further improvement, the lower end face of the aforementioned ear plate is provided with several protrusions that abut against the aforementioned support base.

[0011] As a further improvement, the aforementioned ear plate and conductive sheet are integrally formed.

[0012] As a further improvement, the aforementioned clearance hole is a strip-shaped hole extending to the left and right, and the aforementioned conductive sheet and the embedded part are slidably pre-installed on the upper and lower sides of the aforementioned clearance hole.

[0013] As a further improvement, after the above-mentioned elastic buckle is engaged with the conductive sheet, the front and rear walls of the elastic buckle fit into the mounting hole.

[0014] Another aspect of this utility model provides a BIPV carbon steel bracket, including a main water tank and a connecting component with the structure described above; the support base of the connecting component is fixedly connected across the top of the main water tank, and the lower end face of the photovoltaic panel abuts against the upper end face of the main water tank; the pressure block of the connecting component abuts against the upper end face of the photovoltaic panel; the conductive sheet pierces the oxide film on the surface of the photovoltaic panel; and the static electricity generated by the photovoltaic panel is discharged sequentially through the conductive sheet, the support base (1), and the main water tank (600).

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Firstly, this invention achieves pre-installation of the conductive sheet and the embedded part by setting clearance holes on the support base and mounting holes on the conductive sheet, along with a sliding pre-embedded part, making photovoltaic panel installation more convenient. Secondly, during the fixed installation of the photovoltaic panel, the width of the fixed photovoltaic panel can be adjusted to a certain extent by moving the conductive sheet and the embedded part in the clearance holes, thereby accommodating possible engineering errors between the roof purlins and the main water channel. This structure improves the flexibility and fault tolerance of installation, making installation more convenient and effective under different conditions and environments.

[0017] Secondly, the conductive sheet in this invention is provided with several piercing parts for penetrating the photovoltaic panel support, allowing static electricity on the photovoltaic panel support to be discharged through the conductive sheet, connecting components, and BIPV carbon steel support, preventing static electricity accumulation and effectively improving the overall safety and stability of the photovoltaic system. Furthermore, the second reinforcing rib on the support base provides stable support for the conductive sheet to pierce the outer surface of the photovoltaic panel support.

[0018] Thirdly, in this invention, the conductive sheet has ear plates on both the front and rear sides of the mounting hole. Elastic clips engage with the upper ends of the two ear plates for pre-installation. The lower ends of the ear plates have several protrusions that abut against the support base. During pre-installation, the protrusion structure reduces the space for downward deformation of the ear plates under external force, preventing accidental separation of the elastic clips from the ear plates. Furthermore, the contact between the ear plates and the elastic clips confines the external force during pre-installation to the ear plates, without affecting the overall structure of the conductive sheet, thereby improving overall reliability.

[0033] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0034] In the description of this utility model, the terms "part", "side", "end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] like Figure 1 and Figure 2 As shown, this application provides a connection assembly for photovoltaic panel installation, including a support base 1, an embedded part 2, a pressure block 3, and a bolt 4. The support base 1 is provided with a clearance hole 11. The lower end of the bolt 4 passes through the pressure block 3 and the clearance hole 11 in sequence and is threadedly connected to the embedded part 2. The assembly also includes a conductive sheet 5, which is provided with a mounting hole 51. The elastic buckle 21 of the embedded part 2 passes through the clearance hole 11 and engages with the front and rear edges of the mounting hole 51.

[0036] In one specific embodiment, reference is made to... Figure 1 and Figure 5 The support base 1 is installed on the main water tank 600. The embedded part 2 passes through the clearance hole 11 and the mounting hole 51 from the bottom of the support base 1 and is then snapped into the upper end face of the mounting hole 51. Furthermore, the embedded part 2 and the conductive sheet 5 can slide radially along the bolt 4 within the clearance hole 11. During installation, the photovoltaic panel 700 is laid on top of the conductive sheet 5 on the support base 1, and then the photovoltaic panel 700 is clamped by the pressure block 3. Obviously, this structure allows for the pre-installation of the embedded part 2 and the conductive sheet 5, and by sliding and adjusting the position of the embedded part 2 and the conductive sheet 5, the width of the fixed photovoltaic panel 700 is adjusted to a certain extent, simplifying the installation process and reducing installation time. By locking with the bolt 4, the photovoltaic panel 700 is pressed down, so that the conductive sheet 5 is tightly fitted with the frame of the photovoltaic panel 700, and the static electricity generated on the photovoltaic panel 700 is discharged.

[0037] Furthermore, such as Figure 5As shown, the photovoltaic panel 700 is sandwiched between the conductive sheet 5 and the pressure block 3. Since the support structure of the photovoltaic panel 700 is usually made of metal materials such as aluminum alloy, an oxide film easily forms on its surface. Therefore, in this embodiment, the conductive sheet 5 is provided with several piercing portions for piercing the oxide film on the surface of the photovoltaic panel 700. Specifically, the upper surface of the conductive sheet 5 is provided with several annular protrusions 52, forming the aforementioned piercing portions. After the conductive sheet 5 pierces the oxide film, it contacts the internal conductive layer and discharges static electricity.

[0038] As a preferred option, such as Figure 1 , Figure 2 and Figure 3 As shown, the conductive sheet 5 has a rectangular cross-section. Several second reinforcing ribs 13 are arranged around the aforementioned clearance hole 11. More specifically, the second reinforcing ribs 13 are integrally formed metal protrusions, located on the front and rear sides of the strip-shaped hole, and parallel to the long side of the strip-shaped hole. In this embodiment, annular protrusions 52 are located at the four corners of the conductive sheet 5, with two annular protrusions 52 at each corner. The annular protrusions 52 are positioned above the second reinforcing ribs 13. When the pressure block 3 is locked to the support base 1, the second reinforcing ribs 13 provide stable support for the annular protrusions 52, allowing the annular protrusions 52 to better pierce the outer surface of the photovoltaic panel 700 bracket.

[0039] like Figure 1 and Figure 2 As shown, the aforementioned pressure block 3 is a double-sided pressure block, with both its left and right sides extending to form abutment portions 32. The abutment portions 32 are provided with strip-shaped grooves to enhance the friction of the abutment surfaces. A flat washer 34 and a spring washer 33 are sequentially fitted between the upper end face of the pressure block 3 and the bolt cap 41. The flat washer 34 provides a flat and stable surface to help disperse the pressure between the bolt cap 4 and the pressure block 3, while the spring washer 33 provides a continuous tightening force to prevent the bolt 4 from loosening due to vibration or other factors.

[0040] like Figure 1 and Figure 3 As shown, the conductive sheet 5 has ear plates 53 on both the front and rear sides of the mounting hole 51, and elastic buckles 21 are engaged with the upper ends of the two ear plates 53. The purpose of setting the ear plates 53 is twofold: firstly, to realize the pre-installation of the conductive sheet 5 and the embedded part 2; secondly, during pre-installation, to limit the force of the elastic buckles 21 on the conductive sheet 5 to the ear plates 53, so as to avoid deformation of the outer periphery of the conductive sheet 5 due to force, which would lead to structural damage and thus affect the conductivity.

[0041] Furthermore, several protrusions 54 are provided on the lower end face of the ear plate 53 to abut against the support base 1. Specifically, when the conductive sheet 5 is thin, the ear plate 53 is prone to downward deformation under external forces, such as the weight of the embedded part 2 itself, shaking during installation, or collisions, which may cause the elastic buckle 21 to accidentally separate from the ear plate 53. With the protrusions 54 provided, when the ear plate 53 deforms downward, the protrusions 54 abut against the upper surface of the support base 1, which can prevent the ear plate 53 from deforming further, thereby preventing the embedded part 2 from accidentally separating from the conductive sheet 5.

[0042] In one specific embodiment, the ear plate 53 and the conductive sheet 5 are integrally formed. The conductive sheet 5 is formed by cutting two partition grooves at the corner of the mounting hole 51 to form the mounting hole 51 and the ear plate 53.

[0043] like Figure 1 and Figure 2 As shown, the clearance hole 11 is a strip-shaped hole extending left and right. The elastic buckle 21 is integrally formed with the embedded part 2. Specifically, the elastic buckle 21 consists of two symmetrically arranged snap-fit ​​connectors. The bolt 4 hole is located between the two snap-fit ​​connectors. The distance between the two snap-fit ​​connectors matches the front and rear width of the strip-shaped hole. The conductive sheet 5 and the embedded part 2 are pre-installed on the upper and lower sides of the clearance hole 11, sliding left and right. After the elastic buckle 21 and the conductive sheet 5 are engaged, the front and rear walls of the elastic buckle 21 fit into the mounting hole 51.

[0044] like Figure 1 and Figure 2 As shown, the support base 1 includes a connecting plate 1a with a clearance hole 11, and connecting ears 1c are fixed on both 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.

[0045] In one specific embodiment, a clearance hole 11 is located in the middle of the connecting plate 1a, with its length direction aligned with the line connecting the two connecting ears 1c. The embedded part 2 and the conductive sheet 5 are slidably engaged with the clearance hole 11 via a snap-fit ​​connector. 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. This structure accommodates potential engineering errors between the purlin 800 and the main water tank 600 during the installation of the photovoltaic panel 700, significantly reducing the stringent requirements for the precision of construction and materials, improving the flexibility and tolerance of installation, and making the installation work more convenient and efficient.

[0046] In one specific embodiment, the left and right sides of the support base 1 extend and bend upwards and then downwards respectively to form a ramp structure 1b. The outer side of the ramp structure 1b bends downwards to form a connecting ear 1c. The connecting ear 1c further includes a horizontal support portion and a bent connecting portion. More specifically, one side of the support base 1 bends upwards by 30°, extends a certain distance, and then bends downwards by 30° to form a Z-shaped structure with a 150° concave angle. The outer side of the second bend extends a certain distance and then bends downwards by 90°. The other side of the support base 1 is symmetrically arranged in the same manner. Thus, the middle horizontal portion of the support base 1 forms the aforementioned connecting plate 1a, and the two sides are connecting ears 1c. The connecting plate 1a and the connecting ears 1c are connected by the ramp structure 1b, and the horizontal height of the connecting plate 1a is lower than the horizontal height of the connecting ears 1c on both sides. When the connecting components are subjected to frontal pressure, vibration, or lifting force, the Z-shaped structures on both sides will deform to a certain extent and return to their original state, effectively absorbing and releasing energy. The ramp structure 1b provides a smooth transition, reduces stress concentration, and helps extend the service life of the entire structure.

[0047] like Figure 1 and Figure 2 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 one specific embodiment, the first reinforcing ribs 12 are respectively provided at the bends between the ramp structure 1b and the connecting plate 1a and the connecting ear 1c.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, both the front and rear sides of the connecting plate 1a extend and bend downwards to form flanges 14, which enhances the overall strength of the connecting plate 1a. At the same time, the flanges 14 are easy to process and eliminate the sharp edges of the plate. During installation, the flanges 14 on the front and rear sides of the connecting plate 1a can be held more easily and avoid scratching the palms.

[0049] Another aspect of this utility model provides a carbon steel bracket for BIPV, such as... Figure 1 , Figure 4 and Figure 5 As shown, the BIPV carbon steel support frame consists of components such as purlins 800 and main water channels 600. In this embodiment, both the purlins 800 and the main water channels 600 are made of carbon steel. Typically, the purlins 800 are horizontally and evenly arranged between the roof trusses and fixed by welding or connectors. The main water channels 600 are arranged perpendicular to the purlins 800. In one specific embodiment, multiple main water channels 600 are spaced apart and fixed to the upper surface of the purlins 800 by bolts 4. The spacing between two adjacent main water channels 600 matches the left and right width of the photovoltaic panels 700, ensuring a certain drainage gap between each photovoltaic panel 700.

[0050] like Figure 5 As shown, the longitudinal section of the main water tank 600 is M-shaped. The upper surface of the M-shaped main water tank 600 is flat and used to abut against the frame of the photovoltaic panel 700. Multiple of the aforementioned connecting components are arrayed on the upper end of the main water tank 600. Specifically, the support base 1 of the connecting component is fixedly connected horizontally above the main water tank 600, and the lower surface of the photovoltaic panel 700 abuts against the upper surface of the main water tank 600. The pressure block 3 of the connecting component abuts against the upper surface of the photovoltaic panel 700. Figure 5 As shown, the annular protrusion 52 of the conductive sheet 5 should be set to a sufficient height to pierce the frame of the photovoltaic panel 700. The conductive sheet 5 pierces the oxide film on the surface of the photovoltaic panel 700, and the static electricity generated by the photovoltaic panel 700 is discharged in sequence through the conductive sheet 5, the support base 1 and the main water tank 600.

[0051] like Figure 4 As shown, several auxiliary water tanks 900 are horizontally arranged at the upper end of the main water tank 600 to further improve drainage efficiency, reduce the risk of overflow, and prevent water from contacting and corroding the bracket and photovoltaic panel 700 for a long time.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
