Description

Technical Field

[0001] This utility model relates to the field of solar energy support technology, and in particular to a modular aluminum alloy photovoltaic base support bracket. Background Technology

[0002] The unique design of the solar panel mounting system allows the modules to be angled according to different regions, thus fully utilizing local solar energy resources and maximizing the power generation efficiency of the solar panels. Furthermore, detailed analysis and practical application of the photovoltaic module connection methods, material selection, and support load stress analysis have been conducted, resulting in excellent physical properties such as earthquake resistance, wind resistance, snow pressure resistance, and corrosion resistance, enabling the photovoltaic modules to be applied in a wider range of regions.

[0003] Most aluminum alloy photovoltaic support brackets on the market are currently made up of front columns, rear columns, diagonal beams, and diagonal bracing beams, which are fixed together by a directional angle. However, this type of support bracket has the following shortcomings in actual use: When assembling the support bracket, the operator needs to carry fasteners, hexagonal nuts, washers, and fastening tools (wrench, screwdriver, or electric wrench) to fix the directional angle to the connection nodes of the front column, rear column, diagonal beam, or diagonal bracing beam with fasteners. Due to the structural limitations of some connection positions, it is not convenient to insert fasteners and insert tools, resulting in a large workload and difficulty in assembling the entire support bracket, reducing the convenience and efficiency of the support bracket assembly.

[0004] In view of this, it is particularly important to design and manufacture an aluminum alloy photovoltaic base support that can achieve tool-free quick assembly of the base support bracket and effectively improve the convenience and efficiency of assembly. This is especially important in the design, manufacturing and actual use of base support brackets. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the assembly of existing aluminum alloy photovoltaic base supports is labor-intensive and difficult, which reduces the convenience and efficiency of the installation and disassembly of the base supports. Therefore, a modular aluminum alloy photovoltaic base support is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular aluminum alloy photovoltaic support bracket includes a front column, a rear column located to the left of the front column, an inclined beam located between the upper ends of the front and rear columns, and an inclined bracing beam located between the rear column and the inclined beam. The upper ends of the front column, the upper ends of the rear column, and the upper and lower ends of the inclined bracing beam are rotatably mounted with directional angles. The front column, the rear column, and the inclined beam are provided with a modular locking mechanism on the side facing the directional angle for tool-free convenient fixing of the directional angle to the front column, the rear column, and the inclined beam.

[0007] As a further description of the above technical solution: The module locking mechanism includes a limiting plug fixed at one end of the direction angle, a limiting buckle fixed at the right end of the rear column and the lower end of the inclined beam for accommodating the limiting plug, and a rotary locking part located at the right end of the rear column and the lower end of the inclined beam at the other end of the direction angle.

[0008] As a further description of the above technical solution: The rotary locking part includes an L-shaped rotary buckle rotatably mounted on the right end of the rear column and located on the upper side of the directional angle and on the lower end of the inclined beam and located on the right side of the directional angle, an inner thread seat fixed on the free end of the L-shaped rotary buckle, an outer threaded stud screwed onto the inner thread seat by thread, and an inner threaded hole opened on the directional angle and matching the outer threaded stud.

[0009] As a further description of the above technical solution: A knob is installed at the outer end of the external stud, and the outer surface of the knob has multiple inwardly recessed grooves arranged in a ring array.

[0010] As a further description of the above technical solution: The right end of the rear column and the lower end of the inclined beam are both fixedly connected with parallel guide rails, and a guide groove corresponding to the guide rail is opened on the side of the directional angle close to the guide rail.

[0011] As a further description of the above technical solution: The lower ends of both the front and rear columns are fixedly connected to a base, and the base has fixing holes at both ends.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, the original base support structure has been scientifically and rationally improved. A limiting plug and an internal threaded hole are set at the directional angle. At the same time, limiting buckles, L-shaped buckles, external studs, and knobs are set on the rear column and the inclined beam. The limiting plug at the directional angle can be pre-slid into the limiting buckle under the rear column or the inclined beam. Then, the L-shaped buckle on the rear column or the inclined beam can be rotated in the directional angle direction to fit. Finally, when the knob is held and rotated, the external stud on the L-shaped buckle can be screwed into the internal threaded hole of the directional angle, thus locking the directional angle to the rear column or the inclined beam. This structure enables tool-free modular assembly of the base support components, effectively reducing the workload and difficulty of the base support installation and disassembly operations, thereby improving the convenience and efficiency of the base support assembly or disassembly operations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a modular aluminum alloy photovoltaic base support bracket, including a front column 1, a rear column 2 located on the left side of the front column 1, an inclined beam 3 located between the upper ends of the front column 1 and the rear column 2, and an inclined bracing beam 4 located between the rear column 2 and the inclined beam 3. The upper ends of the front column 1, the upper ends of the rear column 2, and the upper and lower ends of the inclined bracing beam 4 are all rotatably mounted with a direction angle 5. The front column 1, the rear column 2, and the inclined beam 3 are provided with a modular locking mechanism on the side facing the direction angle 5 for tool-free convenient fixing of the direction angle 5 to the front column 1, the rear column 2, and the inclined beam 3.

[0017] Specifically, such as Figure 1-3 As shown, the module locking mechanism includes a limiting plug 501 fixed on one end of the direction angle 5, a limiting buckle 6 fixed on the right end of the rear column 2 and the lower end of the inclined beam 3 and used to accommodate the limiting plug 501, and a rotary locking part provided on the right end of the rear column 2 and the lower end of the inclined beam 3 and located at the other end of the direction angle 5.

[0018] The rotary locking part includes an L-shaped rotary buckle 7 rotatably installed on the right end of the rear column 2 and located above the direction angle 5 and on the lower end of the inclined beam 3 and located to the right of the direction angle 5, an inner thread seat 701 fixed on the free end of the L-shaped rotary buckle 7, an outer thread 8 screwed onto the inner thread seat 701, and an inner thread hole 502 opened on the direction angle 5 and matching the outer thread 8. When the outer thread 8 on the L-shaped rotary buckle 7 is screwed into the inner thread hole 502 of the direction angle 5, the direction angle 5 can be stably locked between the limit buckle 6 and the L-shaped rotary buckle 7.

[0019] In addition, a knob 801 is installed on the outer end of the external stud 8, which makes it easy for the operator to hold and rotate the external stud 8 for adjustment. The knob 801 has multiple inwardly recessed grooves in a ring array on its outer side, which effectively increases the contact area and contact friction between the knob 801 and the operator's hand.

[0020] Specifically, such as Figure 1-3 As shown, the right end of the rear column 2 and the lower end of the inclined beam 3 are both fixedly connected with parallel guide slides 10. The side of the directional angle 5 closest to the guide slide 10 is provided with a guide groove 503 corresponding to the guide slide 10. The setting of the guide slide 10 and the guide groove 503 improves the accuracy of guiding the upper limit plug 501 of the directional angle 5 into the limit buckle 6. On the other hand, after the directional angle 5 is fixed, it can effectively limit the lateral displacement, shaking and abnormal noise of the directional angle 5 on the rear column 2 or the inclined beam 3, thereby improving the structural load-bearing stability after the bottom support bracket assembly is fixed.

[0021] Specifically, such as Figure 1-3 As shown, the lower ends of the front column 1 and the rear column 2 are both fixedly connected to a fixed base 9. The left and right ends of the fixed base 9 are provided with fixing holes 901. The fixed base 9 and the fixing holes 901 are provided to facilitate the front column 1 and the rear column 2 to be fixed to the ground or fixed base by fasteners, thereby realizing the fixing operation of the lower end of the bottom support bracket.

[0022] Working principle: When assembling the base support bracket, the operator first takes the front column 1 and the rear column 2, aligns the direction angle 5 of the upper end of the front column 1 and the rear column 2 with the corresponding limiting buckle 6 on the inclined beam 3, and then inserts the limiting plug 501 on the direction angle 5 into the limiting buckle 6 on the inclined beam 3. Next, the L-shaped buckle 7 at the corresponding position on the inclined beam 3 is rotated in the direction angle 5 direction. When the free end of the L-shaped buckle 7 is in contact with the direction angle 5, the operator can then hold and rotate it. Turn knob 801 to screw the external stud 8 inward into the internal threaded hole 502 of the direction angle 5. At this time, the direction angle 5 of the front column 1 and the rear column 2 can be fixed together below the inclined beam 3. Finally, take the inclined support beam 4 and align the direction angle 5 at the upper and lower ends of the inclined support beam 4 with the corresponding limiting buckles 6 on the inclined beam 3 and the rear column 2. Then, the direction angle 5 can be fixed according to the above operation steps. At this time, the inclined support beam 4 can be triangularly fixed between the rear column 2 and the inclined beam 3, thus completing the tool-free and convenient installation operation of the bottom support bracket.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
