Description

Technical Field

[0001] This utility model relates to the installation structure of a photovoltaic system, and more particularly to an angle-adjustable balcony photovoltaic bracket with a control rod at the top and a photovoltaic system. Background Technology

[0002] Previous adjustable-angle balcony photovoltaic designs, such as Figure 1 , Figure 2 As shown, all methods involve drilling bolt holes on the rods and adjusting the bracket angle by installing the rods into different bolt holes. This can meet the requirements for adjusting the angle of the photovoltaic bracket, but the bracket needs to be disassembled and reassembled when adjusting the bracket angle, which is inconvenient.

[0003] Other adjustable-angle balcony photovoltaic support structures include Figure 3 , Figure 4 As shown, one type uses a sliding groove structure, but the sliding groove structure at the connection part is complex and has a high processing cost. Furthermore, because the angle adjustment point is located outside the balcony, personnel cannot adjust the angle from the outside; the entire bracket must be removed from the balcony before the angle can be adjusted, making operation inconvenient. Another type uses a pulley hinge, but this type of hinge can only withstand tension, not compression. When the photovoltaic module is subjected to upward wind suction, the hinge will deform, causing the module angle to change. It is significantly affected by wind loads and has poor stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable balcony photovoltaic bracket with a control rod at the top.

[0005] This utility model relates to an adjustable balcony photovoltaic bracket, comprising a vertical rod, a diagonal rod, a horizontal brace, and a hook. The hook is fixed relative to the vertical rod to form an assembly for installation on the balcony railing. The diagonal rod is used to support the photovoltaic module, and the upper end of the diagonal rod is hinged to the vertical rod. It also includes a control rod, a sliding rod, and a locking device. The sliding rod and the vertical rod form a slidable nested structure. The upper end of the sliding rod is connected to the control rod, and the lower end is hinged to one end of the horizontal brace. The other end of the horizontal brace is hinged to the diagonal rod. The sliding rod and the vertical rod are locked together by a locking device, which allows for releasable locking.

[0006] The adjustable-angle balcony photovoltaic bracket provided by this utility model also includes the following auxiliary technical solutions:

[0007] The sliding rod is placed inside the vertical rod as an internal rod.

[0008] The vertical rod has a groove on its flange plate and a bolt that can slide up and down along the groove. The built-in rod and the cross brace are connected by bolts. The groove restricts the diagonal rod and the vertical rod to form an initial angle greater than zero.

[0009] The locking component is a bolt that connects the vertical rod to the opening in the inner rod flange plate.

[0010] This also includes purlins, which are horizontally fixed to the diagonal braces to form a support for installing photovoltaic modules.

[0011] The web of the diagonal brace and / or purlin has multiple perforated holes arranged along its length.

[0012] The bracket and photovoltaic module are fixed together by bolts and clamps, and the hollow holes serve as the through holes for the bolts.

[0013] The hook opening is equipped with a sealing rod, which is hinged to the end of the hook by rotating a bolt, and the other end is fastened to the hook rod body by a snap-fit ​​structure.

[0014] The lower end of the vertical bar has a clamp for fixing it to the railing.

[0015] A photovoltaic system is also provided, including the aforementioned angle-adjustable balcony photovoltaic bracket and photovoltaic modules mounted on the photovoltaic bracket.

[0016] The implementation of this utility model has the following technical effects:

[0017] The photovoltaic (PV) modules are fixed to the PV support frame. The tilt angle of the PV support frame and modules is adjusted according to the sunlight angle, allowing the system to more effectively receive solar energy and increase module power generation. After the PV support frame and modules are installed on the building's balcony, they do not need to be disassembled. The tilt angle of the PV modules can be adjusted via the control rod at the top of the support frame, reducing the disassembly and assembly process, making operation convenient and quick, and increasing operational safety. Openings at the flange / web plates of the support frame components reduce the overall weight of the support frame while ensuring component strength. These openings can also be used to adjust the bolt connection positions of the components, thereby adjusting the spacing between the support frame and purlins, accommodating the installation needs of modules of different sizes, increasing the applicability of the PV support frame. All connections between PV support frame components and between the support frame and modules are made using bolts, requiring only one bolt for each connection node, facilitating on-site installation and disassembly, and saving construction costs. The PV support frame is fixed to the balcony railing via upper hooks and hook sealing rods, and lower clamps, increasing the overall structural stability and safety. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figures 5 to 9 As shown, this utility model relates to an angle-adjustable balcony photovoltaic bracket, which allows for adjustment of the tilt angle of the photovoltaic module 410 after installation. The structure includes a vertical rod 100, a diagonal rod 200, a horizontal brace 300, a purlin 400, a control rod 500, an internal rod 600, a hook 700, and a clamp 800. The photovoltaic bracket can be made of hot-dip galvanized steel, zinc-aluminum-magnesium steel, or aluminum alloy, and is suitable for installing photovoltaic modules 410 on building balconies.

[0029] A bolt hole 920 is made at the base of the hook 700, and it is installed on the upper end of the vertical rod 100 by bolts 910. A sealing rod 710 is set at the opening of the hook 700. The sealing rod 710 is hinged to the end of the hook 700 by rotating the bolt 910, and the other end is fastened to the hook 700 rod body by a snap-fit ​​structure 720. After the vertical rod 100 is installed on the balcony by the hook 700, the upper end of the hook 700 is fixed to the railing by the sealing rod 710. The lower end of the vertical rod 100 has a clamp 800, which can be adjusted and closed by bolts 910. The clamp 800 fixes the vertical rod 100 to the railing, enhances the reliable connection between the photovoltaic bracket and the balcony, and ensures the stability and safety of the photovoltaic bracket.

[0030] The upper end of the diagonal brace 200 is hinged to the vertical brace 100. The diagonal brace 200 is arranged longitudinally and can be used alone to support the photovoltaic module 410. Preferably, purlins 400 are provided, which are laterally fixed to the diagonal brace 200 to form a transverse arrangement. The two together serve as supports for installing the photovoltaic module 410. The webs of the diagonal brace 200 and the purlins 400 have multiple perforations arranged along the length direction. This reduces the overall weight of the support while ensuring the strength of the components, and also reduces the overall steel consumption and material cost. The positions of the perforations in the webs can be used to adjust the connection positions of the bolts 910, thereby adjusting the spacing between the support and the purlins 400, which can accommodate the installation requirements of modules of different sizes and increase the applicability of the photovoltaic support.

[0031] The sliding rod is nested on the vertical rod 100 and slides up and down. The sliding rod is placed inside the vertical rod 100 as an internal rod 600. The internal design can reduce the volume and weight of the balcony photovoltaic bracket and increase the effective load. Furthermore, the cross-sectional dimensions of the vertical rod 100, internal rod 600, diagonal rod 200, and horizontal brace 300 decrease from large to small, forming a nested structure. The smaller cross-section can slide and rotate inside the larger cross-section.

[0032] The built-in rod 600 has a small upper cross-section and a large lower cross-section. Its upper end connects to the control rod 500, and its lower end is hinged to one end of the cross brace 300. The other end of the cross brace 300 is hinged to the diagonal rod 200. The control rod 500 moves up and down, causing the built-in rod 600 to move up and down within the vertical rod 100, thereby changing the angle between the cross brace 300 and the diagonal brace, thus adjusting the angle of the photovoltaic bracket. Once the target angle is reached, a locking device is used to releasably lock the vertical rod 100 and the built-in rod 600 relative to each other. In a further embodiment, the locking device can be a bolt 910 connected to the opening in the flange plate of the vertical rod 100 and the built-in rod 600. The built-in rod 600 is fixed with bolts 910 to fix the angle of the photovoltaic bracket.

[0033] After the photovoltaic brackets and modules are installed on the building's balcony, they do not need to be disassembled. The tilt angle of the photovoltaic modules can be adjusted from inside the balcony using the control rod 500, reducing the disassembly and assembly process, making operation convenient and quick, and increasing operational safety.

[0034] Furthermore, the flange plate of the vertical rod 100 is provided with a sliding groove 110. The built-in rod 600 and the cross brace 300 are connected by bolts 910. The bolts 910 slide up and down along the sliding groove 110. This structure can achieve reliable sliding in a compact and lightweight manner. By adjusting the control rod 500 up and down, the bolts 910 connecting the built-in rod 600 and the cross brace 300 can be driven to slide up and down along the sliding groove 110, thereby adjusting the tilt angle of the photovoltaic bracket. Another function of the sliding groove 110 is to limit the angle between the inclined rod 200 and the vertical rod 100 to between 5° and 45°. The sliding groove 110 limits the initial angle between the inclined rod 200 and the vertical rod 100 to be greater than zero, so that the upper control rod 500 can be pushed with a small force.

[0035] Furthermore, all components of the photovoltaic support are fixed with bolts 910, and the support and photovoltaic modules 410 are fixed with bolts 910 and pressure blocks (the hollow holes serve as through holes for the bolts 910). Each connection node requires only one bolt 910, which makes on-site installation and disassembly convenient and saves construction costs.

[0036] This utility model has the following advantages:

[0037] 1. The control rod 500, the built-in rod 600, and the cross brace 300 are connected by bolts 910 to form a linkage mechanism. The tilt angle of the photovoltaic bracket can be adjusted by the upper control rod 500.

[0038] 2. The bolt 910 connecting the cross brace 300 and the built-in rod 600 can slide along the angle adjustment groove 110, driving the diagonal rod 200 to rotate. The diagonal rod 200 can form an angle between 5° and 45° with the vertical rod 100.

[0039] 3. The diagonal bar 200 and the vertical bar 100 must have a certain initial angle so that the upper control bar 500 can be pushed with a small force;

[0040] 4. The tilt angle of the module can be varied within a certain range, which can keep the tilt angle of the module at an optimal tilt angle, ensuring the power generation on the front side while meeting safety requirements;

[0041] 5. The cross-sectional dimensions of the vertical rod 100, the built-in rod 600, the diagonal rod 200, and the horizontal brace 300 decrease from large to small, forming a nested structure. The smaller cross-section can slide and rotate inside the larger cross-section.

[0042] 6. The opening in the web plate can be used to adjust the connection position of the 910 bolts of the component, thereby adjusting the spacing of the bracket and purlin 400, which can meet the installation requirements of components of different sizes;

[0043] 7. While ensuring the strength of the photovoltaic support components, the flange plate... / The opening in the web plate reduces the overall weight and material cost of the scaffold;

[0044] 8. All connections between components are made with 910 bolts, which facilitates on-site installation and disassembly and saves construction costs.

[0045] 9. The upper hook 700 of the photovoltaic bracket has a hook 700 sealing rod 710, which can lock the top horizontal bar of the railing inside the hook 700. The lower end has a clamp 800 connected to the vertical bar of the railing 100. The bracket as a whole forms an upper hanging and lower clamp structure system, which is safe and reliable.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
