Description

Technical Field

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

[0002] Solar photovoltaic (PV) panels are used to convert solar energy into electrical energy to power electrical equipment or feed power into the grid to meet electricity needs. Typically, several PV panels are combined to form a photovoltaic array, which is then fixed to a supporting structure on a building roof, ground, or water. During installation, the PV panel frames are usually secured to a supporting beam using clamps, bolts, and nuts. However, this conventional clamping method is not satisfactory. Firstly, installation is cumbersome; bolts need to penetrate the clamps and supporting beams from top to bottom, making nut installation and tightening inconvenient and inefficient. Furthermore, with a large number of panels, the support beam has many holes, which can affect its rigidity and load-bearing capacity. Secondly, over time, factors such as temperature changes, wind, and vibration can cause the bolts to loosen, leading to loosening of the PV panels and poor structural stability. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a photovoltaic panel installation structure for a rooftop photovoltaic system, including a photovoltaic bracket and several photovoltaic panels, wherein the photovoltaic bracket has a supporting keel, and the photovoltaic panels are connected to the supporting keel through a connecting component; characterized in that: the connecting component includes a pressure block, a pull rod, and a pull-down plate; the cross-section of the pressure block is U-shaped, and the upper edges of its two side plates are bent outward and extended to form pressure plates, and a through hole is provided at the corresponding position of the two side plates of the pressure block; one end of the pull rod passes through the through holes on the two side plates in sequence; the pull-down plate is L-shaped and consists of two pieces, the upper sides of the vertical plates of the two pull-down plates are rotatably connected to the two ends of the pull rod through a rotating shaft, and the horizontal plates of the two pull-down plates face opposite directions;

Its width is greater than or equal to the width of the side plate of the pressure block, and its depth is greater than or equal to the distance between the lower side of the pressure block bottom plate and the upper side of the pull rod. The pressure block of the connecting assembly extends into the receiving groove. The length direction of the pull rod is consistent with the length direction of the receiving groove, and both ends of the pull rod are diffracted to both sides of the supporting keel. The horizontal plates of the two pull plates are located on the lower side of the supporting keel and are fixed to the supporting keel by locking bolts.

[0006] The frame of the photovoltaic panel extends between the pressure plate of the pressure block and the supporting keel, and the pressure plate presses the photovoltaic panel firmly onto the supporting keel.

[0007] Furthermore, the horizontal plate of the pull-down plate is provided with a screw hole, and the locking bolt is threadedly connected to the screw hole, with its screw end abutting against the lower side of the supporting keel.

[0008] Furthermore, a locking nut is fixed on the upper or lower side of the horizontal plate of the pull-down plate. A through hole is provided on the horizontal plate corresponding to the screw hole of the locking nut.

[0025] Example: See Figure 1 , Figure 2 A photovoltaic panel installation structure for a rooftop photovoltaic system includes a photovoltaic support frame and several photovoltaic panels 1. The photovoltaic support frame has load-bearing keels 2, and further includes columns and load-bearing beams. The load-bearing keels 2 are spaced apart above the load-bearing beams, and the length direction of the load-bearing keels 2 is perpendicular to the length direction of the load-bearing beams. In practice, the load-bearing keels 2 are made of aluminum alloy profiles, thereby improving structural stability and reducing weight.

[0026] The photovoltaic panel 1 is connected to the supporting keel 2 via a connecting assembly. The connecting assembly includes a pressure block 3, a pull rod 4, and a pull-down plate 5. The pressure block 3 has a U-shaped cross-section, with the upper edges of its two side plates bent outwards and extending to form pressure plates. A through hole is provided at the corresponding position on the lower part of each side plate of the pressure block 3, and one end of the pull rod 4 passes through the through holes on the two side plates in sequence. The pull-down plate 5 is L-shaped and consists of two pieces. The upper sides of the vertical plates of the two pull-down plates 5 are rotatably connected to the two ends of the pull rod 4 via a rotating shaft 6, and the horizontal plates of the two pull-down plates 5 face each other. In implementation, two arms 10 are formed on the upper side of the pull-down plate 5, and the two arms 10 are located on both sides of the pull rod 4. The two arms 10 and the pull rod 4 are connected by a pin that passes through the two arms 10 and the pull rod 4, which makes assembly more convenient.

[0027] The upper side of the supporting keel 2 is provided with a receiving groove. The length direction of the receiving groove is perpendicular to the length direction of the supporting keel 2 and extends through both sides of the supporting keel 2. Its width is greater than or equal to the width of the side plate of the pressure block 3, and its depth is greater than or equal to the distance between the lower side of the bottom plate of the pressure block 3 and the upper side of the pull rod 4. The pressure block 3 of the connecting assembly extends into the receiving groove. The length direction of the pull rod 4 is consistent with the length direction of the receiving groove, and both ends of the pull rod 4 radiate to both sides of the supporting keel 2. The horizontal plates of the two pull-down plates 5 are located on the lower side of the supporting keel 2 and are fixed to the supporting keel 2 by locking bolts 7. To further improve the connection stability, the vertical plates of the pull-down plates 5 are also connected to the supporting keel 2 by self-tapping screws.

[0028] In one embodiment, the horizontal plate of the pull-down plate 5 is provided with a screw hole, and the locking bolt 7 is threadedly connected to the screw hole, with its screw end abutting against the lower side of the bearing keel 2; the structure is simple and easy to process.

[0029] In another embodiment, a locking nut 8 is fixed to the upper or lower side of the horizontal plate of the pull-down plate 5, and the locking nut 8 is welded to the horizontal plate. A through hole is provided on the horizontal plate corresponding to the screw hole of the locking nut 8. The screw of the locking bolt 7 passes through the locking nut 8 and the through hole, and is threadedly connected to the locking nut 8, with its screw end abutting against the lower side of the supporting keel 2. This further improves the connection stability of the locking bolt 7. As an optimization, an elastic washer 9 is provided between the bolt head of the locking bolt 7 and the horizontal plate, which can absorb vibration, reduce the impact of vibration on the locking bolt 7, and ensure the connection stability of the locking bolt 7. A gasket is provided between the elastic washer 9 and the bolt head of the locking bolt 7.

[0030] The frame of the photovoltaic panel 1 extends between the pressure plate of the pressure block 3 and the supporting keel 2, and the pressure plate presses the photovoltaic panel 1 onto the supporting keel 2.

[0031] This solution involves inserting the frame of the photovoltaic panel 1 between the pressure plate of the pressure block 3 and the supporting keel 2. Then, the pressure block 3 is pulled downwards and tightened using locking bolts 7 on the underside of the supporting keel 2, thereby pressing the photovoltaic panel 1 firmly. The installation process of the connecting components all takes place under the supporting keel 2, making installation convenient and improving efficiency. During installation, no holes need to be drilled in the supporting keel 2, ensuring its structural stability and strength, thus enhancing the stability of the entire photovoltaic system. Furthermore, the pull rod 4 and the pull-down plate 5 form a U-shaped structure that holds the supporting keel 2, increasing the stress points on the connectors and further improving connection stability.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
