Description

Technical Field

[0001] This utility model belongs to the field of photovoltaics and relates to the support of photovoltaic panels, specifically to a solar photovoltaic panel support frame that is easy to install. Background Technology

[0002] A photovoltaic (PV) power generation system is a clean energy system that directly converts solar energy into electrical energy using the photovoltaic effect. Its core component, the photovoltaic panel, uses the photoelectric conversion properties of semiconductor materials to convert photon energy from solar radiation into direct current (DC) electricity. When deploying PV power generation systems in complex terrains such as mountainous areas, steel trusses are commonly used as the supporting foundation for the PV panels. However, this steel truss system requires a large number of prefabricated steel components. Taking the construction of a 10㎡ PV array (using four 550W modules, 2279×1134mm / module) as an example, the truss supporting the array mainly consists of main beams, secondary beams, diagonal braces, and column components. This requires two 80×80×3mm square steel main beams, four 50×50×2.5mm angle steel secondary beams, eight 40×40×2mm square steel diagonal braces, and four 100×100×4mm square steel columns, totaling 250kg. This presents significant challenges when transporting and handling such systems in mountainous areas. Because the truss installation requires a large number of components, the installation process is cumbersome and inefficient. After the truss is erected, the solar photovoltaic panels need to be installed on the truss. The installation of the solar photovoltaic panels requires specialized equipment or multiple people (usually an 8-person team) to lift the photovoltaic panels to the installation position. This segmented construction method results in low construction efficiency and poses safety hazards due to working at height. Utility Model Content

[0003] This invention addresses the technical problem of cumbersome and inefficient assembly and installation of solar photovoltaic panel support frames by providing an easy-to-install support frame. The support frame utilizes a modular design to reduce weight and improve transportation convenience. Its adjustable hinge structure allows for both flattening and erection of the support rods, enabling the photovoltaic panels to be installed on the ground before being erected as a whole, thus enhancing installation convenience and efficiency.

[0004] The technical solution adopted by this utility model is as follows: a solar photovoltaic panel support frame that is easy to install is provided, including a support column, an assembly column and a vertical column are hinged to the top and bottom of the support column, and a connecting ring and a sleeve are provided on the outer side wall of the support column. The connecting ring is fixedly fitted to the outer side wall of the support column, and the sleeve is movably fitted to the outer side wall of the support column. A flange is coaxially fixedly connected to the bottom of the outer side wall of the vertical column. A connecting plate is coaxially fixedly connected to the assembly column, and a frame is fixedly installed on the connecting plate. A connecting rod is hinged to the bottom of the frame along the circumferential direction, and the other end of the connecting rod is hinged to the connecting ring.

[0005] The modular design of the support column, assembly column, and upright column facilitates transportation. When supporting the solar photovoltaic panel, the upright column is first installed on the support surface. After hinged one end of the support column to the upright column, the support column is laid flat, and the assembly column is hinged to its other end. The frame is then installed on the connecting plate of the assembly column, laid flat, and positioned and fixed on the assembly column. The solar photovoltaic panel is then installed onto the frame, simplifying the installation process. Next, the support column is pulled up along the upright column to a vertical position, and the sleeve slides down along the support column and fits into the upright column, thus connecting the support column and upright column into a single structure, keeping the support column vertical. The support angle of the frame for the solar photovoltaic panel is then adjusted, and the connecting rings on the frame and support column are connected by connecting rods to support the frame, ensuring the stability and reliability of the photovoltaic panel support.

[0006] To further optimize this technical solution, the support column, assembly column, and upright column are all cylindrical. Both ends of the support column are hinged to the assembly column and upright column via hinged joints, and the sleeves are threaded to the support column and upright column.

[0007] The cylindrical structure of the support column and the upright column facilitates threaded connection, making operation simple and use stable and reliable.

[0008] To further optimize this technical solution, the hinge pair includes mutually cooperating hinge seats disposed at both ends of the support column and disposed on the assembly column and the upright column, and the hinge seats are connected by means of connectors.

[0009] To further optimize this technical solution, the hinge seat includes a semi-cylindrical protrusion integrally disposed at both ends of the support column and on the assembly column and the upright column, with the axial sections of the protrusions in contact with each other; a through hole is provided on the axial section of the protrusion, and an adapter groove is provided on the arc surface of the protrusion, the diameter of the adapter groove is larger than the diameter of the through hole, and it is coaxially connected with the through hole, and the connector is assembled in the through hole and the adapter groove.

[0010] The protrusions of the semi-columns integrated on the support column, assembly column, and upright column ensure the strength of the components. The through holes and adapter grooves on the protrusions provide assembly positions for the connectors, and the connectors do not protrude from the adapter grooves, so as not to interfere with the movement of the sleeve, ensuring flexibility and reliability in use.

[0011] To further optimize this technical solution, the connector includes a matching hexagon socket bolt and nut, the shank of the hexagon socket bolt is inserted into the through hole, and the head of the hexagon socket bolt and the nut are respectively located in the adapter groove.

[0012] The hex socket head cap screws connect the mounting column and the upright to the support column through the through hole, and the head and nut of the hex socket head cap screws are located in the fitting groove, so as not to interfere with the movement of the sleeve along the support column to the upright, ensuring stable use.

[0013] To further optimize this technical solution, the outer wall of the sleeve is uniformly and fixedly connected with reinforcing ribs along the circumference.

[0014] The reinforcing ribs enhance the strength of the sleeve and facilitate its tightening.

[0015] To further optimize this technical solution, the outer surface of the protrusion is coated with a Teflon coating.

[0016] Teflon coating reduces frictional resistance on the raised axial section, reduces wear on the hinge pair, and extends the service life of the hinge pair.

[0017] To further optimize this technical solution, the bottom of the outer wall of the support column and the bottom of the outer wall of the column are provided with external threads, the inner wall of the sleeve is provided with matching internal threads, and the outer wall of the support column is threaded with a locking nut, which abuts against the end face of the sleeve.

[0018] The internal thread design on the inner wall of the sleeve allows it to move smoothly along the support column and the column. After the sleeve abuts against the end face of the flange, the lock nut abuts against the end face of the sleeve, thereby enhancing the firmness of the sleeve to the support column and the column and ensuring the reliability of the connection.

[0019] To further optimize this technical solution, the bottom surface of the frame and the top surface of the connecting ring are both provided with connecting seats in the circumferential direction, and both ends of the connecting rod are set in the connecting seats and locked and fixed with the connecting seats by means of locking components.

[0020] The connecting rod is connected to the frame and connecting ring through the connecting seat, which is simple in structure and stable and reliable in use.

[0021] To further optimize this technical solution, the locking component includes a bolt that passes through the connecting seat and the connecting rod, and a nut is provided on the bolt.

[0022] Bolts and nuts tighten and fix the connecting rod to the connecting seat. Its simple structure makes the installation of the connecting rod firm and reliable.

[0023] The beneficial effects of this utility model are as follows: 1. The main body of the support frame consists of support columns, assembly columns and uprights. Its modular design makes it easy to disassemble and transport, effectively reducing transportation difficulties. When assembling and using it, the support columns are installed on the uprights and laid flat, and the frames on the assembly columns are also laid flat, making the installation of photovoltaic panels simple and labor-saving, and improving installation and use efficiency. 2. After the photovoltaic panels are installed on the frame, the support column is pulled up to a vertical position, and the sleeve is moved down to connect with the threaded connection of the column. The connection is strengthened by tightening the lock nut, thus connecting the support column and the column into an integrated structure. Then, the assembly column is rotated to adjust the support angle of the frame for the photovoltaic panels, so as to achieve efficient power generation. The frame is connected to the connecting ring on the support column through the connecting rod, which strengthens the support strength of the frame and ensures the reliability of use. 3. The protrusions integrated with the support columns, assembly columns, and uprights enhance the strength of their hinges and ensure reliable use. The heads and nuts of the hexagonal socket bolts are located in the matching grooves of the protrusions, so as not to interfere with the movement of the sleeves. Furthermore, the hinged joints assist in positioning the uprights and assembly columns with the support columns, ensuring reliable use. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see the appendix Figure 1-6A convenient solar photovoltaic panel support frame includes a support column 1. The top and bottom ends of the support column 1 are hinged to assembly columns 2 and upright columns 3. The support column 1, assembly columns 2, and upright columns 3 are cylindrical structures and can be made of hot-dip galvanized steel. Both ends of the support column 1 are hinged to the assembly columns 2 and 3 via hinge joints. The hinge joints are integrally formed semi-cylindrical protrusions 801 on the support column 1, assembly columns 2, and upright columns 3. The axial sections of the protrusions 801 are in contact with each other, and the axial sections of the protrusions 801 are coated with Teflon to reduce axial stress. To reduce wear on the cross-section and extend service life, a through hole 8011 is provided on the axial cross-section of the protrusion 801, and an adapter groove 8012 is provided on the arc surface of the protrusion 801. The diameter of the adapter groove 8012 is larger than the diameter of the through hole 8011 and is coaxially connected with the through hole 8011. The connecting parts for the hinge pair are assembled in the through hole 8011 and the adapter groove 8012. The connecting parts include matching hexagonal socket head cap screws 9 and nuts 10. The shank of the hexagonal socket head cap screw 9 is inserted into the through hole 8011, and the head of the hexagonal socket head cap screw 9 and the nut 10 are respectively located in the adapter groove 8012. Please see the appendix Figure 1-3 and appendix Figure 6 A flange 301 is fixedly connected to the bottom of the outer wall of the column 3. The flange 301 is fixedly installed on the support surface by anchor bolts 13, etc., to support the column 3, the support column 1 and the assembly column 2. A sleeve 5 is movably fitted on the support column 1. The outer wall of the support column 1 is provided with an external thread 101. The sleeve 5 is threaded to the support column 1. Its inner wall is provided with an internal thread 502. The sleeve 5 moves down along the support column 1 and is threaded to the column 3. After abutting with the end face of the flange 301, the sleeve 5 positions and supports the support column 1 to keep it vertical. A reinforcing rib 501 is fixedly connected to the outer wall of the sleeve 5 along the axial direction. The reinforcing rib 501 enhances the strength of the sleeve 5 and facilitates the screwing of the sleeve 5 to ensure the flexibility of use. A locking nut 11 is threaded to the outer wall of the support column 1. After the locking nut 11 abuts with the end face of the sleeve 5, it enhances the thread engagement strength between the sleeve 5 and the support column 1 and the column 3, and enhances the connection firmness. Please see the appendix Figure 1-3 and appendix Figure 5A connecting plate 201 is coaxially fixedly connected to the assembly column 2. A frame 6 is fixedly installed on the connecting plate 201. After the solar photovoltaic panel is installed on the frame 6, the angle of the solar photovoltaic panel is adjusted by rotating the assembly column 2 along the support column 1 through the hinge. The assembly column 2 and the support column 1 are tightened and fixed by the hexagonal bolts 9 and nuts 10. A connecting rod 7 is hinged to the bottom of the frame 6 in the circumferential direction. A connecting ring 4 is also fixedly connected to the outer wall of the support column 1. The connecting ring 4 is located above the sleeve 5. The other end of the connecting rod 7 is hinged to the connecting ring 4. A connecting seat 12 is connected to both the frame 6 and the connecting ring 4. The connecting rod 7 is locked to the connecting seat 12 by the locking device. A bolt 13 passes through the connecting seat 12 and the connecting rod 7. A nut 10 is connected to the bolt 13. Its structure is simple and the assembly is simple and flexible.

[0028] The working principle of this easy-to-install solar photovoltaic panel support frame is as follows: To ensure convenient transportation and flexible use, the main body of the support frame adopts a modular design, consisting of support column 1, assembly column 2, and upright column 3. Before transportation, it can be disassembled into independent components and packed and bundled separately, effectively reducing transportation difficulty. Structurally, support column 1, assembly column 2, and upright column 3 can all be solid constructions to ensure the strength of the support frame. Compared with traditional truss structure support frames, this support frame significantly reduces the number of main support components (taking the construction of a 10㎡ photovoltaic array as an example, the four 550W photovoltaic panels only require one set of high-strength alloy steel support column 1, assembly column 2, and upright column 3 components), reducing the overall weight by 30% and significantly improving transportation and installation efficiency. When assembling and using the support frame, first, the upright column 3 is fixedly installed on the mountain support surface through flange 301, and the upright column 3 serves as the foundation of the support frame. Then, support column 1 is hinged to upright column 3 in a folded position, and assembly column 2 is hinged to support column 1. The frame 6, mounted on the assembly column 2 via the connecting plate 201, is also in a flat position. The stability of the frame 6 is ensured by tightening the hinge joint between the assembly column 2 and the support column 1, thus facilitating the installation of the solar photovoltaic panels on the frame 6. After the solar photovoltaic panels are installed, the support column 1 is pulled upwards along the hinge joint. Once the support column 1 is vertically erected, the friction between the support column 1 and the hinge seat 8 of the column 3 is increased by tightening the hex bolts 9 and nuts 10 on the hinge joint, thus initially fixing the support column 1. Subsequently, the sleeve 5 on the support column 1 moves down and is threadedly connected to the column 3. Since the head of the hex bolt 9 and the nut 10 are both located in the adapter groove 8012 of the hinge seat 8, they do not obstruct the movement of the sleeve 5. This allows the sleeve 5 to connect the support column 1 and the column 3 into a single structure. The reinforcing rib 501 on the outer wall of the sleeve 5 enhances the strength of the sleeve 5 and the connection strength between the support column 1 and the column 3. After the end face of the sleeve 5 abuts against the flange 301, the locking nut 11 is tightened to prevent the sleeve 5 from loosening and to ensure the reliability of the connection between the support column 1 and the column 3. After the support column 1 is fixed in place, the hinge joint between the support column 1 and the assembly column 2 is loosened, allowing the assembly column 2 to rotate along the hinge joint, thereby adjusting the tilt angle of the solar photovoltaic panel. After adjustment, the hinge joints are retightened, and the connecting rod 7 is installed on the frame 6. The other end of the connecting rod 7 is then connected to the connecting ring 4 on the support column 1. This stabilizes the position of the frame 6, ensuring the support strength for the photovoltaic panels and distributing the stress on the hinge joints, thus improving the overall structural reliability. This completes the installation of the solar photovoltaic panels. The installation time can be reduced from 8 person-hours / 10㎡ for truss structures to 4 person-hours / 10㎡, lowering labor costs. Furthermore, the operation is simple, flexible, and efficient.
