Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation equipment technology, and in particular to a windproof photovoltaic panel mounting structure for houses. Background Technology

[0002] Currently, existing photovoltaic panel mounting structures typically include support frames, photovoltaic panel mounting beams, and clamping assemblies for fixing photovoltaic modules. During installation, the clamping assemblies are locked onto the photovoltaic panel mounting beams with bolts, thereby achieving a fixed connection between the photovoltaic modules and the photovoltaic panel mounting beams. Since photovoltaic systems are exposed to the outdoor environment for a long time, especially under conditions of strong winds, typhoons, and continuous wind vibration, photovoltaic modules will be subjected to periodic wind loads and vibrate.

[0003] However, most existing bridging components are mainly fixed to the photovoltaic panel mounting beams by bolt preload. When subjected to long-term vibration, the bridging components are prone to slight displacement along the photovoltaic panel mounting beams, or even loosening, which leads to a decrease in the fixing stability of the photovoltaic modules. In severe cases, it may also cause the photovoltaic modules to shift, damage the connection parts, or even fall off, which not only affects the safe operation of the power generation system, but also increases maintenance costs.

[0004] Therefore, how to provide a windproof photovoltaic panel mounting structure for buildings that can effectively suppress the displacement and loosening of locking components under wind vibration, improve the installation stability of photovoltaic modules and the overall wind resistance performance has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a windproof photovoltaic panel mounting structure for houses, which solves the above technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A windproof photovoltaic panel mounting structure for buildings includes a foundation pier, a front-end transition seat on the foundation pier, a low-level support column on the foundation pier and spaced apart from the front-end transition seat, a high-level support column, a middle transition seat rotatably mounted on the top of the low-level support column, a rear-end transition seat rotatably mounted on the top of the high-level support column, a photovoltaic panel main support beam mounted on the top surface of the front-end transition seat, the middle transition seat, and the rear-end transition seat, a photovoltaic panel mounting beam detachably mounted on the top of the photovoltaic panel main support beam, a photovoltaic module mounted on the top surface of the photovoltaic panel mounting beam, and a locking component for fixing the photovoltaic module to the photovoltaic panel mounting beam. The photovoltaic panel mounting beam is U-shaped, with the top of the photovoltaic panel mounting beam bent from both sides towards the center and from top to bottom to form a bent section. The photovoltaic panel mounting beam has concave sections on both sides of the center that are recessed towards the center. The locking assembly includes a Z-shaped locking block that fits with the photovoltaic module, a pressing block that fits with the bending part, and a fastener that passes through the bottom of the Z-shaped locking block and screws into the pressing block. The pressing block has an inner groove at the contact position with the bending part, and a serrated protrusion is provided at the inner groove position of the pressing block. The bottom shape of the bending part is a tooth shape that fits with the protrusion.

[0007] Furthermore, the photovoltaic panel mounting beam is provided with a plurality of spaced second slots, and the photovoltaic panel mounting beams are provided with connectors, the connectors being provided with a plurality of first slots having the same shape as the second slots.

[0008] Furthermore, the front-end adapter, the middle adapter, and the rear-end adapter have the same structure.

[0009] Furthermore, the front-end adapter includes a triangular body, a connecting plate located on the bottom surface of the triangular body and connected to the photovoltaic module, and a connecting bolt located on the top surface of the triangular body and rotatably connected to the low-position support column and the high-position support column.

[0010] Furthermore, a reinforcing rod is provided between the low-position support column, the high-position support column and the main support beam of the photovoltaic panel, an upper connecting adapter is provided between the reinforcing rod and the main support beam of the photovoltaic panel, and a lower connecting adapter is provided between the reinforcing rod and the low-position support column and the high-position support column.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are: This windproof photovoltaic (PV) panel mounting structure utilizes a locking assembly consisting of PV panel mounting beams, Z-shaped clamps, lower pressure blocks, and fasteners to quickly clamp and secure the PV modules. The lower pressure block has a serrated protrusion in its inner groove, and the bottom surface of the bent portion of the PV panel mounting beam has a matching toothed structure. When the fasteners are tightened, the serrated protrusions and toothed structures engage to create a limiting effect. In windy conditions, the PV modules experience continuous vibration due to wind loads. The displacement tendency caused by this vibration is blocked by the engaging toothed structure, preventing the lower pressure block from sliding along the length of the PV panel mounting beam. This creates a wind-induced self-locking effect, effectively preventing the locking assembly from loosening, shifting, or falling off even under long-term wind-induced vibration conditions. This significantly improves the wind resistance stability and safety of the PV modules after installation, and enhances the overall structure's vibration resistance, deformation resistance, and overturning resistance, significantly improving the safety and stability of the PV system in windy conditions.

[0012] The photovoltaic panel mounting beam has a bending section at the top. When locked, the lower pressure block and the bending section form an upper and lower covering clamping state, which not only increases the clamping area and clamping strength, but also further restricts the lateral displacement of the locking components, so that the photovoltaic modules and the photovoltaic panel mounting beam form a more solid and reliable connection, thereby improving the overall vibration resistance and wind resistance performance.

[0013] A multi-point triangular support system is formed by the front-end adapter, the middle adapter, and the rear-end adapter. By utilizing the characteristics of triangular structure that is stable under force and not easily deformed, a stable load-bearing frame is formed between the main beam of the photovoltaic panel and the low-level support column and the high-level support column. When subjected to strong winds, the wind load can be transferred and dispersed through multiple support points, reducing the phenomenon of local structural stress concentration and improving the overall rigidity and anti-overturning ability of the support.

[0014] By installing reinforcing rods between the main beam of the photovoltaic panel and the low-level and high-level support columns, and in conjunction with the upper and lower connecting adapters to form multiple closed triangular force-bearing units, wind loads can be transmitted through the main beam of the photovoltaic panel, reinforcing rods, low-level and high-level support columns, and upper and lower connecting adapters to form a multi-path force transmission structure. This effectively reduces the sway amplitude of the main beam of the photovoltaic panel, improves the overall bending and torsional resistance, and maintains good structural stability even in strong winds.

[0015] The low-position support column, the middle adapter and the rear adapter adopt a rotating connection structure, which can adjust the installation tilt angle of the photovoltaic module according to the light conditions of the installation area to obtain better light reception. After the tilt angle is adjusted, the triangular support structure can still maintain a stable stress state, thus balancing power generation efficiency and wind resistance performance.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to Figures 1 to 10 This embodiment provides a windproof photovoltaic panel mounting structure for a building, including a foundation pier 1, a front-end adapter 2 mounted on the foundation pier 1, a low-level support column 3 mounted on the foundation pier 1 and spaced apart from the front-end adapter 2, a high-level support column 4, a middle adapter 5 rotatably mounted on the top of the low-level support column 3, a rear-end adapter 6 rotatably mounted on the top of the high-level support column 4, a photovoltaic panel main support beam 7 mounted on the top surfaces of the front-end adapter 2, the middle adapter 5, and the rear-end adapter 6, and a detachable... The photovoltaic panel mounting beam 8, the photovoltaic module 9 disposed on the top surface of the photovoltaic panel mounting beam 8, and the locking component 10 for fixing the photovoltaic module 9 to the photovoltaic panel mounting beam 8 are provided. The photovoltaic panel mounting beam 8 is U-shaped. The top of the photovoltaic panel mounting beam 8 is bent from both sides to the middle and from top to bottom to form a bending part 81. The photovoltaic panel mounting beam 8 has concave parts 82 on both sides of the middle part. The concave parts 82 facilitate the initial positioning of the pressure block 102. The pressure block 102 slides in the photovoltaic panel mounting beam 8 to prevent it from falling.

[0029] The locking assembly 10 includes a Z-shaped locking block 101 that fits with the photovoltaic module 9, a pressing block 102 that fits with the bending portion 81, and a fastener 103 that passes through the bottom of the Z-shaped locking block 101 and screws into the pressing block 102. The pressing block 102 has an inner groove 105 at the contact position with the bending portion 81, and a serrated protrusion 106 is provided at the position of the inner groove 105 of the pressing block 102. The bottom of the bending portion 81 is shaped like a tooth 104 that fits with the protrusion 106.

[0030] During installation, first install the front-end adapter 2 on the foundation pier 1. Then, vertically install the low-position support column 3 and the high-position support column 4 on the foundation pier 1. Place the photovoltaic panel main support beam 7 on the top surface of the rear-end adapter 6 on the high-position support column 4, the top surface of the middle adapter 5 on the low-position support column 3, and the top surface of the front-end adapter 2. Since the height of the high-position support column 4 is greater than the height of the low-position support column 3, the photovoltaic panel main support beam 7 and the foundation pier 1 will form an inclined angle, which is beneficial for the installation of the photovoltaic module 9 in an inclined state. Then, connect the photovoltaic panel mounting beam 8 to the photovoltaic panel main support beam 7 with bolts and place the photovoltaic module 9 on the top surface of the photovoltaic panel mounting beam 8. Next, attach the top of the Z-shaped clip 101 to the photovoltaic module 9 and the bottom of the Z-shaped clip 101 to the photovoltaic panel mounting beam 8. Then, place the lower pressure block 102 on top of the photovoltaic panel mounting beam 8, slide the lower pressure block 102 to move it under the Z-shaped clip 101, and then screw the fastener 103 through the Z-shaped clip 101 and the lower pressure block 102 to fix it. This completes the quick installation of the photovoltaic module 9. The bottom shape of the bent part 81 is toothed 104 and fits with the sawtooth protrusion 106 of the lower pressure block 102. The lower pressure block 102 and the Z-shaped clip 101 are less likely to shift when subjected to wind vibration, and have a good windproof effect.

[0031] The photovoltaic panel mounting beam 8 is provided with a plurality of spaced second slots 83, and the photovoltaic panel mounting beams 8 are provided with a connector 11, which is provided with a plurality of first slots 12 with the same shape as the second slots 83.

[0032] When the length of the photovoltaic panel mounting beam 8 is insufficient and splicing is required, the new photovoltaic panel mounting beam 8 is attached to the original photovoltaic panel mounting beam 8. Then, the second slot 83 on the photovoltaic panel mounting beam 8 is aligned with the first slot 12 on the connector 11. Finally, the photovoltaic panel mounting beam 8 and the connector 11 are locked and fixed together by passing bolts through the second slot 83 and the first slot 12.

[0033] The front-end adapter 2, the middle adapter 5, and the rear-end adapter 6 have the same structure. The front-end adapter 2 includes a triangular body 201, a connecting plate 202 located on the bottom surface of the triangular body 201 and connected to the photovoltaic module 9, and a connecting bolt 203 located on the top of the triangular body 201 and rotatably connected to the low-position support column 3 and the high-position support column 4.

[0034] Since the tilt angle of the photovoltaic module 9 will be adjusted according to the actual site conditions and geographical location, the tilt angle between the main support beam 7 of the photovoltaic panel and the low support column 3 and the high support column 4 is not fixed. Since the top of the triangular body 201 is rotatably installed on the main support beam 7 of the photovoltaic panel through the connecting bolt 203, and the triangular body 201 is installed on the low support column 3, the high support column 4 and the foundation pier 1, it can be installed at any angle.

[0035] A reinforcing rod 13 is provided between the low-position support column 3, the high-position support column 4 and the photovoltaic panel main support beam 7. An upper connecting adapter 14 is provided between the reinforcing rod 13 and the photovoltaic panel main support beam 7. A lower connecting adapter 15 is provided between the reinforcing rod 13 and the low-position support column 3 and the high-position support column 4.

[0036] The reinforcing rod 13 helps to enhance the structural stability between the main supporting beam 7 of the photovoltaic panel and the low-position support column 3 and the high-position support column 4. The upper connecting adapter 14 and the lower connecting adapter 15 disperse the wind load through multi-point force distribution, significantly improving the overall wind resistance performance, especially effectively suppressing the swaying and deformation of the frame in strong wind environments.
