Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a portable balcony photovoltaic module bracket. Background Technology

[0002] Currently, there are various structural forms of photovoltaic (PV) brackets for balconies. PV brackets consist of multiple components, with the PV modules mounted on them. The brackets are then secured to the balcony railing using multiple fixing points. Traditional balcony PV brackets typically use separate packaging for each component, requiring professional installers or user self-assembly. This presents several problems: the separate packaging and self-assembly not only increase packaging waste but also lead to a cumbersome installation process and a poor user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a portable balcony photovoltaic module support structure that can be pre-assembled in the factory, folded during packaging, and extended during installation, thereby minimizing the workload of users in self-assembly and solving the problem of low efficiency in on-site assembly of modular components.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A portable balcony photovoltaic module support structure includes a column, an inclined beam with its upper end hinged to the column, and a bracing assembly with its first end hinged to the inclined beam and its second end hinged to the column. The photovoltaic module is mounted on the inclined beam. The column is U-shaped, and the upper end of the inclined beam is hinged to the inner side of the column. The bracing assembly includes a first side support plate and a second side support plate arranged parallel to each other in the transverse direction. The first ends of the first and second side support plates are hinged to the inclined beam, and the second ends of the first and second side support plates are respectively hinged to the transverse sides of the column. When separated from the inclined beam, the bracing assembly is in a retracted state. In the retracted state, the inclined beam is stored inside the column. In the retracted state, the first and second side support plates are arranged side-by-side on the transverse sides of the column.

[0006] Preferably, the diagonal bracing assembly includes a first diagonal brace and a second diagonal brace connected along the length direction. The first end of the first diagonal brace is hinged to the diagonal beam, and the second end of the second diagonal brace is hinged to the column. A diagonal brace length adjustment structure is provided between the first diagonal brace and the second diagonal brace.

[0007] Preferably, the diagonal brace length adjustment structure includes an elongated hole provided on one of the first diagonal brace and the second diagonal brace, a limiting hole provided on the other, and a diagonal brace limiting clip connecting the elongated hole and the limiting hole.

[0008] Preferably, the inclined brace limiting clip has a circular ring structure and limiting flanges at both ends in the lateral direction. The inclined brace limiting clip passes through the elongated hole and the limiting hole, and the limiting flange at one end is limited to the elongated hole, while the limiting flange at the other end is limited to the limiting hole.

[0009] Preferably, the column is connected to a clamp that connects to the balcony railing.

[0010] Preferably, the clamp includes a first clamp connected to the upper end of the column. The first clamp includes a hook body and a hook bolt. The hook body is suspended on the horizontal bar of the balcony railing and connected to the hook bolt. The hook body is clamped and fixed to the horizontal bar by the hook bolt.

[0011] Preferably, the clamp includes a second clamp connected to the lower part of the column. The second clamp includes a clamp body and a clamp bolt. The clamp body cooperates with the column to clamp onto the horizontal bar of the balcony railing and is connected to the clamp bolt. The clamp body is clamped and fixed to the horizontal bar by the clamp bolt.

[0012] Preferably, the bottom wall of the column is provided with a waist-shaped fixing hole, and the side wall of the column is provided with a hinge hole.

[0013] Preferably, the inclined beam is equipped with side pressure blocks for fixing the photovoltaic modules.

[0014] Preferably, the side pressure block has a support part supported on the inclined beam, a pressing part pressed against the photovoltaic module frame, and a connecting part connecting the support part and the pressing part, and a pressure block bolt is connected between the connecting part and the inclined beam.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. The inclined beam is equipped with photovoltaic modules, which can be fixed to the inclined beam as a single unit at the factory. The column is U-shaped, with an inner space for storing the inclined beam. The column, inclined beam, and bracing components can all be pre-assembled at the factory, but the inclined beam and bracing components are temporarily separated and not connected. This allows the bracing components and inclined beam to be stored separately. The inclined beam can be stored inside the column, and the first and second side support plates of the bracing components are arranged side-by-side on both sides of the column when stored. During on-site installation, the bracing components are in an extended state and connected to the inclined beam to support it, ensuring the inclined beam is angled and the photovoltaic modules installed on it are at an optimal power generation angle.

[0017] When packaged, the entire support structure is a flat component with relatively long length and width, but relatively small overall thickness, requiring less packaging space. This allows for the completion of most of the assembly work while reducing packaging space.

[0018] During on-site installation, the diagonal bracing components are first switched from the retracted state to the extended state. Then, the diagonal beam is connected to the diagonal bracing components. Only the column and balcony railing need to be fixed. Compared to the original method of connecting the diagonal beam to the column, connecting the diagonal bracing components to the column, and installing the photovoltaic modules on-site, this method reduces the on-site installation process, speeds up the installation, solves the problem of low efficiency in assembling separate parts on-site, and improves the ease of installation.

[0019] 2. The diagonal bracing assembly includes a first diagonal brace and a second diagonal brace connected along their length. The first end of the first diagonal brace is hinged to the inclined beam, and the second end of the second diagonal brace is hinged to the column. A diagonal brace length adjustment structure is provided between the first and second diagonal braces. Therefore, by adjusting the relative positions of the first and second diagonal braces through the diagonal brace length adjustment structure, the length of the diagonal bracing assembly can be adjusted, thereby adjusting the tilt angle of the inclined beam and the angle of the photovoltaic module. This optimizes the illumination angle, adjusts the amount of irradiance received by the photovoltaic module, and solves the problem of insufficient irradiance in traditional balcony photovoltaic systems, resulting in low power generation from the photovoltaic panels.

[0020] 3. The diagonal brace length adjustment structure includes an elongated hole on one of the first and second diagonal braces, a limiting hole on the other, and a diagonal brace limiting clip connecting the elongated hole and the limiting hole. The diagonal brace limiting clip can move along the elongated hole and can be locked in place after movement, thereby adjusting the overlap length of the first and second diagonal braces, i.e., adjusting the length of the diagonal brace assembly, to adjust the tilt angle of the diagonal beam and realize the angle adjustment of the photovoltaic module.

[0021] 4. The column is connected to a clamp for connection with the balcony railing. Referring to existing technology, common balcony railings typically have horizontal and vertical bars, such as two parallel horizontal bars connected vertically between them. A clamp can be used to fix either the horizontal or vertical bar. Specifically, the clamp is fixed to the horizontal bar, comprising a first clamp connected to the upper end of the column and a second clamp connected to the lower part of the column. The first clamp connects to an upper horizontal bar, and the second clamp connects to a lower horizontal bar. During installation on the balcony railing, the first clamp is first suspended and fixed to the upper horizontal bar to secure the upper part of the column; then the second clamp is fixed to the lower horizontal bar to secure the lower part of the column. Using clamps for fixing is convenient and reliable. The clamps are chosen to be fixed to the horizontal bars because the overall force on the photovoltaic support structure is downward, and fixing them to the vertical bars carries the risk of downward slippage.

[0022] 5. The fixing hole is designed as an oblong hole, so that the relative position of the hook bolt and the clamp bolt can be adjusted to correspond with the position of the crossbar, and it is also convenient to fix it with crossbars of different diameters.

[0023] 6. Side pressure blocks for fixing the photovoltaic module frame are installed on the inclined beam. Therefore, the side pressure blocks are assembled with the inclined beam at the factory by pressure block bolts, and the photovoltaic module is fixed as a whole.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0043] The primary application scenario for this embodiment is the installation of photovoltaic power generation devices on balconies with railings, as described below. Figures 1 to 11As shown, a portable balcony photovoltaic module support structure 1 includes a column 11, an inclined beam 12 hinged to the column at its upper end, and a bracing assembly with its first end hinged to the inclined beam and its second end hinged to the column. A photovoltaic module 2 is mounted on the inclined beam 12. The column 11 is U-shaped, with a U-shaped cross-section forming an internal storage cavity. The upper end of the inclined beam 12 is hinged to the inner side of the column. The bracing assembly includes a first side support plate and a second side support plate arranged parallel to each other laterally. The first ends of the first and second side support plates are hinged to the inclined beam, and the second ends are respectively hinged to the lateral sides of the column 11. After the first end of the bracing assembly is separated from the inclined beam, the bracing assembly and the inclined beam can be stored separately. The inclined beam 12 has a retracted (folded) state when stored inside the column during packaging and an extended state for power generation during installation. The inclined beam 12 is separated from the bracing assembly in the retracted state and connected to the bracing assembly in the extended state. The diagonal bracing assembly has a retracted (or folded) state and an extended state. In the retracted state, the diagonal bracing assembly is separated from the inclined beam, and the first side support plate and the second side support plate are respectively arranged side by side on the horizontal sides of the column. In the extended state, the diagonal bracing assembly is connected to the inclined beam to support the inclined beam, so that the inclined beam is set at an angle, and the photovoltaic modules installed on it can be in a better power generation angle.

[0044] The inclined beam is equipped with photovoltaic modules, which can be fixed to the inclined beam as a whole at the factory. The column is U-shaped, with an inner space for storing the inclined beam. The column, inclined beam, and inclined bracing components can all be pre-assembled at the factory, but the inclined beam and inclined bracing components are temporarily separated and not connected. This allows the inclined beam to be stored inside the column. The first and second side support plates of the inclined bracing components are arranged side-by-side on both sides of the horizontal axis of the column when stored. Figure 11 As shown, the whole is a flat component, relatively long in length and width, but relatively thin overall, requiring less packaging space. Thus, it completes most of the assembly work while reducing packaging space.

[0045] During on-site installation, the diagonal bracing components are first switched from the retracted state to the extended state. Then, the diagonal beam is connected to the diagonal bracing components. Only the column and balcony railing need to be fixed. Compared to the original method of connecting the diagonal beam to the column, connecting the diagonal bracing components to the column, and installing the photovoltaic modules on-site, this method reduces the on-site installation process, speeds up the installation, solves the problem of low efficiency in assembling separate parts on-site, and improves the ease of installation.

[0046] In this embodiment, the diagonal bracing assembly includes a first diagonal brace 13 and a second diagonal brace 14 connected along its length. The first end of the first diagonal brace 13 is hinged to the inclined beam, and the second end of the second diagonal brace 14 is hinged to the column. A diagonal brace length adjustment structure is provided between the first diagonal brace 13 and the second diagonal brace 14. Naturally, both the first side support plate and the second side support plate include the first diagonal brace 13 and the second diagonal brace 14. Therefore, by adjusting the relative positions of the first and second diagonal braces through the diagonal brace length adjustment structure, the length of the diagonal bracing assembly can be adjusted, thereby adjusting the tilt angle of the inclined beam and the angle of the photovoltaic module. This optimizes the illumination angle, adjusts the irradiance received by the photovoltaic module, and solves the problem of insufficient irradiance in traditional balcony photovoltaic systems, resulting in low power generation from the photovoltaic panels.

[0047] In some embodiments, the diagonal brace length adjustment structure includes an elongated hole 131 on one of the first and second diagonal braces, a limiting hole 141 on the other, and a diagonal brace limiting clip 15 connecting the elongated hole and the limiting hole. The diagonal brace limiting clip 15 can move along the elongated hole 131 and can be engaged and fixed after movement, thereby adjusting the overlap length of the first and second diagonal braces, that is, adjusting the length of the diagonal brace assembly to adjust the tilt angle of the diagonal beam and realize the angle adjustment of the photovoltaic module.

[0048] Of course, it is understandable that other forms of telescopic structures can also be used to achieve length adjustment of the diagonal brace components.

[0049] like Figure 10 As shown, in some embodiments, the inclined brace limiting clip 15 has a circular structure with limiting flanges 151 at both ends in the lateral direction. The inclined brace limiting clip 15 is composed of two half clips fastened together in the axial direction. Each half clip includes a clip post and a limiting flange connected to one end of the clip post. One half clip is located inside the elongated hole, and the other is located outside the limiting hole. They pass through the elongated hole and the limiting hole respectively to fasten and fix the two clip posts. In this way, the inclined brace limiting clip 15 passes through the elongated hole and the limiting hole, with the limiting flange at one end engaging with the elongated hole and the limiting flange at the other end engaging with the limiting hole. The clip post and the elongated hole can be interference-fitted, which facilitates installation. Since this support structure only supports one photovoltaic module and two support structures are arranged side by side in the lateral direction, the engaging force between the inclined brace limiting clip and the elongated hole is sufficient to ensure that the length of the inclined brace module is fixed after the length is adjusted, thus maintaining the angle of the photovoltaic module. Of course, wavy teeth can also be set on both sides of the width of the elongated hole to increase the clamping force between the diagonal brace limiting clip and the elongated hole.

[0050] Specifically, the column 11 is connected to a clamp for connection with the balcony railing. Referring to existing technology, common balcony railings typically have horizontal and vertical bars, such as two parallel horizontal bars connected vertically between them, which can be fixed to the horizontal or vertical bars using clamps. In this embodiment, the clamp is fixed to the horizontal bar. The clamp includes a first clamp connected to the upper end of the column and a second clamp connected to the lower part of the column. The first clamp is connected to an upper horizontal bar, and the second clamp is connected to a lower horizontal bar. The first clamp includes a hook body 111 and a hook bolt. The hook body is suspended on the horizontal bar of the balcony railing and connected to the hook bolt, which clamps and fixes the hook body to the horizontal bar. The second clamp includes a clamp body 112 and a clamp bolt. The clamp body cooperates with the column to clamp onto the horizontal bar of the balcony railing and is connected to the clamp bolt, which clamps and fixes the clamp body to the horizontal bar. When installing on the balcony railing, first suspend and fix the first clamp to the upper horizontal bar to secure the upper part of the column; then fix the second clamp to the lower horizontal bar to secure the lower part of the column. Using clamps for fixing is convenient and reliable. The clamps are chosen to be fixed to the horizontal bar because the overall force on the photovoltaic support structure is downward, and fixing it to the vertical bar risks downward slippage.

[0051] Furthermore, the hook body 111 has an arc segment that connects with the column body, and also has a vertical extension segment parallel to the column. The upper end of the vertical extension segment connects with the arc segment, and a fixing hole is provided on the vertical extension segment. Therefore, the hook bolt passes through the fixing hole on the column and the vertical extension segment to hold and fix the hook body to the crossbar.

[0052] In this embodiment, the hook body and the column body are an integral structure, formed by bending a pre-punched elongated metal profile. The profile can be stainless steel, or aluminum alloy, to avoid corrosion and extend service life. Specifically, the bottom wall of the column (U-shaped structure) has a waist-shaped fixing hole 113 for connection with hook bolts and clamp bolts. This allows the relative positions of the hook bolts and clamp bolts to be adjusted to align with the crossbar position and facilitates fixing to crossbars of different diameters. Additionally, the side wall of the column (U-shaped structure) has a hinge hole 114 for hinged connection to the upper end of the inclined beam and to the first diagonal brace.

[0053] The photovoltaic module 2 has a rectangular structure and is installed horizontally, meaning it extends laterally. Two support structures 1 are arranged side-by-side along the horizontal direction. An inclined beam is perpendicular to the length of the photovoltaic module. Side pressure blocks 16 for fixing the photovoltaic module are installed on the inclined beam; specifically, each inclined beam has a pressure block 16 connected to each side of the photovoltaic module's width. Each side pressure block 16 has a support portion 162 supported on the inclined beam, a pressing portion 161 pressed against the photovoltaic module's frame, and a connecting portion 163 connecting the support portion and the pressing portion. The support portion 162 is perpendicular to the inclined beam, the pressing portion 161 is parallel to the inclined beam, and the connecting portion 163 has an L-shaped structure. Pressure block bolts 164 connect the connecting portion to the inclined beam.

[0054] Because it is installed and used on a balcony, the columns, inclined beams, side pressure blocks and diagonal bracing components are all made of stainless steel. Of course, aluminum alloy materials can also be used to avoid corrosion and extend service life.

[0055] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
