Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, specifically to a fixed base and a balcony photovoltaic system using the fixed base. Background Technology

[0002] Balcony photovoltaics, as a form of distributed photovoltaic power generation, is gradually entering people's lives due to its advantages such as utilizing unused building space and providing local power supply. This technological field aims to combine photovoltaic power generation equipment with building balconies to achieve energy self-sufficiency, providing power support for homes or small spaces, and has significant economic and environmental benefits. In recent years, its application in both civil and public buildings has been continuously explored and expanded.

[0003] Currently, most conventional balcony photovoltaic (PV) installation solutions involve mounting the PV brackets onto the tubular railings of the balcony. The fixing method primarily utilizes hooks and clamps; the hooks are attached to the tubular railings, and then the clamps are used for further tightening, thus securing the PV brackets.

[0004] However, with the development of the construction industry, many existing homes, schools, apartments, and other places use concrete for their balcony railings. Because existing hook and clamp structures cannot be used to connect to concrete railings, the application of balcony photovoltaics in these scenarios is limited. Utility Model Content

[0005] In view of this, the present invention provides a fixed base and a balcony photovoltaic system using the fixed base, so as to solve the problem that the installation components of existing balcony photovoltaic systems cannot be adapted to concrete railings.

[0006] This utility model provides a fixed base, comprising: a fixed plate having a connecting hole for a connector to pass through, the fixed plate being fixedly connected to a mounting wall via the connector; and a mounting plate being fixedly connected to the fixed plate, the mounting plate having a mounting groove suitable for inserting a component to be installed, the mounting groove being suitable for snapping and fixing the component to be installed.

[0007] With the above-described configuration, the connecting holes on the mounting plate, in conjunction with the connectors, ensure a stable connection between the mounting base and the mounting wall. The mounting slots on the mounting plate securely engage the inserted components, maintaining a stable position after installation and reducing displacement or shaking caused by external forces, thus improving the overall stability of the installation structure. The snap-fit ​​fixing method is simple to operate, requiring no complicated steps during installation and improving efficiency. This mounting base is not limited by the material of the railing; whether it's a concrete railing or a mounting wall of other materials, it can be securely installed using suitable connectors, effectively solving the problem of existing balcony photovoltaic installation components being incompatible with concrete railings.

[0008] Optionally, the mounting plate is perpendicular to the fixing plate.

[0009] Through the above arrangement, the vertical structure can form a stable right-angle support system between the fixing plate and the mounting plate. When the to-be-mounted member is inserted into the mounting groove, the vertical structure can enable the fixing plate to transmit more force to the mounting wall surface, reducing the possibility of deformation or damage of the mounting plate due to uneven force, and enhancing the overall load-carrying capacity and stability of the fixing base. During installation, the installer can more intuitively judge the installation position and angle, reducing the installation difficulty and improving the installation efficiency.

[0010] Optionally, a locking portion is connected to the mounting plate, and the locking portion has a locking hole for connecting a locking member.

[0011] Through the above arrangement, when the to-be-mounted member is inserted into the mounting groove, the locking member can be installed in the locking hole to tightly connect the to-be-mounted member and the locking portion. The stability of the to-be-mounted member after installation is enhanced, preventing it from accidentally falling out of the mounting groove due to factors such as vibration and external force pulling during use, effectively improving the fixing effect of the fixing base on the to-be-mounted member, and being able to adapt to more diversified installation scenarios.

[0012] Optionally, the locking portion is fixedly connected to a side edge of the mounting plate away from the fixing plate.

[0013] Through the above arrangement, the locking portion is fixed to the side edge of the mounting plate away from the fixing plate, which plays a locking role without affecting the operational convenience of inserting the to-be-mounted member into the mounting groove. When the to-be-mounted member is installed in place, the locking portion at this position can directly act on the edge portion of the to-be-mounted member, providing effective blocking and fastening force to prevent the to-be-mounted member from falling out of the mounting groove. Moreover, this position is convenient for the installer to operate the locking member, so that the installer can easily install the locking member into the locking hole without complex angle adjustment during installation and later maintenance, achieving quick and efficient fixing and improving the overall installation and maintenance convenience.

[0014] Optionally, the locking portion is perpendicular to the mounting plate.

[0015] Through the above arrangement, the perpendicular locking portion and the mounting plate form a stable right-angle structure, which can effectively enhance the overall mechanical properties. When the locking member is used to connect the to-be-mounted member and the locking portion, the perpendicular structure can better disperse the fastening force applied by the locking member, so that the to-be-mounted member is more evenly stressed, avoiding local deformation or damage due to uneven stress, thereby further improving the fixing effect and ensuring that the to-be-mounted member is stably fixed in the mounting groove.

[0016] Optionally, the locking member is a bolt, and the inner wall of the locking hole has a threaded structure matched with the bolt.

[0017] Through the above arrangement, the cooperation of the bolt and the thread can generate a larger fastening force, effectively preventing the displacement or falling of the to-be-installed part during use.

[0018] Optionally, the locking part is arranged near the opening of the installation groove.

[0019] Through the above arrangement, the position of the locking part after insertion is placed on the sliding path of the insertion part of the to-be-installed part, which on the one hand ensures accurate insertion of the to-be-installed part into the appropriate position, and on the other hand prevents the to-be-installed part from sliding out of the installation groove along the sliding path due to vibration, external force impact and other unexpected situations, thereby enhancing the fixing effect of the fixing base on the to-be-installed part and reducing safety hazards.

[0020] Optionally, the height of the side of the installation groove away from the fixing plate is lower than the height of the installation plate.

[0021] Through the above arrangement, in terms of installation convenience, the height of the side of the installation groove away from the fixing plate is lower, which can form an entrance of the installation groove that is easy for the to-be-installed part to be inserted, without the need for precise alignment of the installation groove, and the to-be-installed part is more smooth when inserted.

[0022] Optionally, the connecting hole has at least two connecting holes arranged along the length direction of the fixing plate, and the connecting hole is a waist-shaped hole extending along the width direction of the fixing plate.

[0023] Through the above arrangement, the fixing plate and the installation wall surface have multiple connection points. Compared with a single connecting hole, this multi-point connection mode can more evenly distribute the force borne by the fixing plate, thereby improving the stability of the connection between the fixing base and the installation wall surface, and ensuring that the fixing base can work stably under various working conditions.

[0024] The utility model also provides a balcony photovoltaic, include: photovoltaic board subassembly and fixed base, photovoltaic board subassembly has support frame and photovoltaic board, photovoltaic board fixed connection in support frame, support frame has the connecting portion for with fixed base cooperation, connecting portion is suitable for inserting the installation groove of installation plate.

[0025] Through the above setting, the installation process is greatly simplified. The connecting part of the support frame is inserted into the installation slot of the installation plate to be preliminarily fixed, which is simple to operate and does not require complex installation tools and skills, thereby reducing the installation difficulty, reducing the time and labor cost required for installation, and improving the installation efficiency of the balcony photovoltaic. The cooperation of the installation slot and the connecting part can effectively limit the displacement of the photovoltaic panel assembly. In daily use, the balcony photovoltaic may be affected by external forces such as wind and vibration. After the connecting part is inserted into the installation slot, the installation slot restricts the connecting part in multiple directions, ensures that the photovoltaic panel assembly remains stable on the fixed base, reduces the risk of component damage caused by displacement, and prolongs the service life of the balcony photovoltaic.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0035] The embodiments of the utility model will be described below in combination with Figures 1 to 5 .

[0036] As Figure 1 indicated, a specific embodiment of the fixing base provided in the present embodiment comprises: a fixing plate 1 and a mounting plate 2.

[0037] Specifically, the fixing plate 1 has a connecting hole 3 for passing through a connecting piece, and the fixing plate 1 is fixedly connected to the mounting wall surface 11 through the connecting piece; the mounting plate 2 is fixedly connected to the fixing plate 1, and the mounting plate 2 has a mounting groove 4 suitable for inserting a to-be-mounted piece, and the mounting groove 4 is suitable for clamping and fixing the to-be-mounted piece.

[0038] In the present embodiment, the fixing plate 1 is firmly fixed on the mounting wall surface 11 such as a concrete guardrail through the connecting hole 3 matched with the connecting piece, solving the problem that the hook and the clamping plate in the prior art cannot be adapted to the concrete guardrail. The mounting plate 2 is fixedly connected to the fixing plate 1 and designed with the mounting groove 4 thereon, so that the balcony photovoltaic support can be conveniently inserted and clamped and fixed. This structure not only simplifies the installation process, but also ensures the stability of the photovoltaic support on the concrete guardrail, avoiding the limitation that the traditional installation method cannot be used on the concrete guardrail. Through this design, the balcony photovoltaic support can be widely applied to the concrete guardrail scene, expanding its application range and solving the installation adaptability problem.

[0039] As Figure 2 indicated, a specific embodiment of the fixing base provided in the present embodiment, the mounting plate 2 is perpendicular to the fixing plate 1.

[0040] Specifically, the mounting plate 2 is perpendicular to the fixing plate 1, so that a stable right-angle structure is formed between the mounting plate 2 and the fixing plate 1. The overall rigidity of the fixing base is enhanced, and the direction of the mounting groove 4 is kept perpendicular to the mounting surface of the fixing plate 1, facilitating the insertion and clamping of the balcony photovoltaic support. The mounting plate 2 can better bear the weight of the photovoltaic support and ensure that the support remains in a horizontal state after installation, avoiding the problem of inclined photovoltaic modules or uneven force caused by improper installation angle.

[0041] As Figure 1As shown, this is a specific embodiment of the fixed base provided in this example. The mounting plate 2 is connected to a locking part 5, and the locking part 5 has a locking hole 6 for connecting the locking member 7.

[0042] Specifically, the locking part 5 allows the mounting plate 2 to connect with the locking element 7 through the locking hole 6, further enhancing the stability between the fixed base and the balcony photovoltaic bracket. The presence of the locking part 5 allows the photovoltaic bracket to be secondary fixed by the locking element 7 after being inserted into the mounting slot 4, preventing the bracket from loosening or falling off under external wind or other forces.

[0043] In other embodiments, the locking part 5 can also be configured as a limiting member with a sliding groove structure. After the balcony photovoltaic and the mounting plate 2 are fixed, the locking part can be switched to limit the snap-fit ​​between the balcony photovoltaic and the mounting plate 2.

[0044] like Figure 3 As shown, this is a specific embodiment of the fixed base provided in this example, wherein the locking part 5 is fixedly connected to the side edge of the mounting plate 2 away from the fixed plate 1.

[0045] Specifically, the locking part 5 and the fixing plate 1 are located on the same side of the mounting plate 2. The locking part 5 is fixedly connected to the edge of the mounting plate 2 away from the fixing plate 1, so that the locking part 5 is located on the outer edge of the mounting plate 2, which facilitates operation and maintenance. This layout allows the locking part 7 to be installed and fixed from the outside, avoiding interference with the fixing plate 1 or other components, and simplifying the installation process.

[0046] like Figure 2 As shown, this is a specific embodiment of the fixed base provided in this embodiment, wherein the locking part 5 is perpendicular to the mounting plate 2.

[0047] Specifically, a right-angle structure is formed between the locking part 5 and the mounting plate 2, which enhances the rigidity of the locking part 5 and ensures that it is not easily deformed or loosened when subjected to external forces. This makes the direction of the locking hole 6 perpendicular to the mounting plate 2, which facilitates the installation and fixation of the locking part 7 and further improves the connection stability between the locking part 7 and the locking part 5.

[0048] like Figure 1 and Figure 5 As shown, this is a specific embodiment of the fixed base provided in this example. The locking element 7 is a bolt, and the inner wall of the locking hole 6 has a threaded structure that mates with the bolt.

[0049] Specifically, the bolt can be tightly connected with the locking hole 6 through threads to form a stable mechanical locking. The connection strength between the bolt and the locking hole 6 is enhanced, and the installation and disassembly of the bolt are more convenient, facilitating later maintenance and adjustment. The threaded connection mode can effectively prevent the bolt from loosening due to vibration or external force in long-term use, ensuring the long-term reliability of the locking piece 7. The connection stability between the fixing base and the photovoltaic support is improved, and the safety and durability of the overall structure are enhanced.

[0050] As shown in Figure 3 , a specific embodiment of the fixing base provided in the present embodiment, the locking part 5 is arranged near the opening of the installation groove 4.

[0051] Specifically, the locking part 5 is arranged near the opening of the installation groove 4, so that the locking piece 7 can immediately fix the balcony photovoltaic support after it is inserted into the installation groove 4. It ensures that the photovoltaic support can be quickly locked during installation, avoiding the risk of sliding or deviation of the support when it is not completely fixed. At the same time, the design of the locking part 5 near the opening of the installation groove 4 makes the operation of the locking piece 7 more convenient.

[0052] It should be noted that the present embodiment does not specify the specific position of the locking part 5 on the edge, as long as the locking piece 7 fixed to the locking part 5 can extend in the direction of the sliding groove and limit the clamping assembly inserted into the sliding groove.

[0053] As shown in Figure 3 , a specific embodiment of the fixing base provided in the present embodiment, the height of the side of the installation groove 4 away from the fixing plate 1 is lower than the height of the installation plate 2.

[0054] Specifically, the height of the side of the installation groove 4 away from the fixing plate 1 is lower than the height of the installation plate 2, so that the installation groove 4 forms a lower opening on the side away from the fixing plate 1, facilitating the insertion and positioning of the balcony photovoltaic support. The lower opening height makes the support more smoothly slide into the installation groove 4, reducing the possibility of jamming or misalignment during installation.

[0055] In addition, in other embodiments, the installation groove 4 can be designed as a groove with a gradually decreasing opening, which facilitates the initial insertion of the balcony photovoltaic support, and as the groove body extends inward, the opening gradually narrows, eventually forming a tight clamping structure.

[0056] As shown in Figure 1 , a specific embodiment of the fixing base provided in the present embodiment, the connecting hole 3 has at least two connecting holes arranged along the length direction of the fixing plate 1, and the connecting hole 3 is a waist-shaped hole extending along the width direction of the fixing plate 1.

[0057] Specifically, two connecting holes 3 are arranged along the length direction of the fixing plate 1 at intervals, so that the fixing plate 1 can be fixed to the mounting wall surface 11 at multiple points through the multiple connecting holes 3, thereby enhancing the overall stability and load-bearing capacity of the fixing base. The extension direction of the waist-shaped hole is along the width direction of the fixing plate 1, thereby providing a larger adjustment range, facilitating fine adjustment of the position of the fixing plate 1 according to actual needs during installation, and ensuring close fitting between the fixing base and the mounting wall surface 11.

[0058] It should be noted that the number of connecting holes 3 is not limited in this embodiment, and can be flexibly adjusted according to specific installation needs and environmental conditions. In scenarios requiring higher stability and load-bearing capacity, the number of connecting holes 3 can be increased to enhance the connection strength between the fixing base and the mounting wall surface 11.

[0059] As shown in Figure 4 , a specific embodiment of the balcony photovoltaic provided in this embodiment includes a photovoltaic panel assembly and a fixing base.

[0060] Specifically, the photovoltaic panel assembly has a support frame 8 and a photovoltaic panel 9, the photovoltaic panel 9 is fixedly connected to the support frame 8, the support frame 8 has a connecting portion 10 for cooperating with the fixing base, and the connecting portion 10 is adapted to be inserted into the mounting groove 4 of the mounting plate 2.

[0061] Further, as shown in Figure 5 , the support frame 8 has a vertical surface for fitting with the mounting plate 2, and a connecting bolt is provided as the connecting portion 10, the connecting portion 10 penetrates the support frame 8 from the vertical surface, the connecting bolt is transversely inserted into the mounting groove 4 of the mounting plate 2, and then locked by being inserted into the locking hole 6 of the locking portion 5 through the locking bolt. The connecting portion 10 of the support frame 8 matches the mounting groove 4 of the fixing base, so that the connecting portion 10 can be smoothly inserted into the mounting groove 4 and stably connected through the clamping structure of the mounting groove 4. This design not only simplifies the installation process between the photovoltaic panel assembly and the fixing base, but also ensures the stability and safety of the photovoltaic panel assembly on the mounting wall surface 11. The cooperation between the connecting portion 10 and the mounting groove 4 enables the photovoltaic panel assembly to be quickly positioned and fixed, reducing the possibility of misalignment or loosening during installation.

[0062] It should be noted that, as shown in Figure 4 , the support frame 8 is connected to the mounting wall surface 11 through four evenly distributed fixing bases, which are respectively located at the edge positions near the top and bottom of the support frame 8. The four evenly distributed fixing bases and the support frame 8 provide a stable support structure for the photovoltaic assembly. Of course, the number of fixing bases can be adjusted according to the size of the installed photovoltaic assembly.

[0063] Working principle:

[0064] The fixed base comprises a fixed plate 1 and a mounting plate 2, the fixed plate 1 is fixed on the concrete guardrail through the connecting hole 3 and the expansion bolt, the mounting plate 2 is provided with a mounting groove 4 and a locking part 5, which are used for inserting and fixing the support frame 8 of the photovoltaic panel assembly. The design of the mounting groove 4 facilitates the quick insertion and positioning of the photovoltaic panel assembly, and the locking part 5 is further enhanced by the screw thread cooperation with the locking hole 6, which further enhances the stability of the connection. The overall structure is fixed by multiple points and the anti-falling design, which ensures the safe and stable installation of the photovoltaic panel assembly on the concrete guardrail, expands the application range of balcony photovoltaic, improves the installation efficiency and reliability, and solves the installation problem of balcony photovoltaic support on the concrete guardrail.

[0065] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the present application.
