Description

[0001] (This application is a divisional application of “Solar Photovoltaic Panel Support System”. The application date of the original application is November 30, 2021, the application number is 202111445469.2, and the name of the invention is “Solar Photovoltaic Panel Support System”.) Technical Field The present invention mainly relates to solar photovoltaic power generation technology, and in particular to a solar photovoltaic panel support system. Background Art

[0002] Solar energy is the energy generated by the continuous nuclear fusion reaction process of sunspots inside or on the surface of the sun. Solar energy has the advantages of abundant resources, longevity, wide distribution, safety, cleanliness and reliable technology. Since solar energy can be converted into many other forms of energy, its application range is very wide. To obtain electricity from solar energy, it needs to be achieved through photoelectric conversion of solar cells.

[0003] When installing existing solar photovoltaic panels, most of them are first installed in an aluminum frame, and then the aluminum frame is connected to the base by bolts. The molding cost of the aluminum frame is extremely high, and the aluminum frame is easy to deform. The weight of the photovoltaic panel is large. After long-term use, the photovoltaic panel will fall off under the action of wind and rain.

[0004] In order to solve the stability problem of the aluminum frame, the prior art also proposes to replace the aluminum frame with a steel frame. The steel frame is composed of a steel frame. In order to ensure that the steel frame has the functions of clamping the photovoltaic panel and connecting the bottom base at the same time, the steel frame is usually provided with an S-shaped frame, that is, there are two upper and lower notches on the steel frame, one notch is used to clamp the photovoltaic panel, and the other notch is used to penetrate the bolts to connect the bottom base. However, this S-shaped frame with upper and lower notches needs to withstand positive and negative wind loads and snow loads. When the load is too large, the lower notch of the photovoltaic frame is prone to deformation and local collapse, which can easily cause the entire support system to collapse. To solve this problem, it is usually adopted to change the thickness of the frame profile to increase the local strength of the frame profile. However, changing the thickness of the frame profile will undoubtedly greatly increase the cost of the frame system. Summary of the invention

In this structure, when the fastening bolt 22 is tightened, the fastening bolt 22 drives the pressing plate 21 to press the connecting groove 12. The pressing plate 21 forms a full support for the connecting groove 12, that is, supports each groove edge of the connecting groove 12. The structure is simple and reliable.

[0079] In this embodiment, the pressing plate 21 is set as a flat plate, which is pressed on the connection grooves 12 of two adjacent steel frames 1 and supports the groove edges, and the fastening bolts 22 are passed through the middle position of the pressing plate 21 and are threadedly connected with the T-nuts 23. The pressing plate 21 is pressed on the connection grooves 12 of two adjacent steel frames 1 and forms a full support for the connection grooves 12 of the two adjacent steel frames 1, which is suitable for the installation and connection of adjacent steel frame units.

[0080] In this embodiment, a plurality of latch teeth 211 are arranged at the bottom of one end of the flat plate located in the connecting groove 12. The arrangement of the latch teeth 211 increases the friction between the flat plate and the connecting groove 12, and has a further anti-retraction function.

[0081] In this embodiment, the top groove edge of the clamping groove 11 is bent upward to form a top horizontal edge, the top horizontal edge is bent downward to form a side vertical edge connected to the connecting groove 12, the bottom groove edge of the connecting groove 12 is bent downward to form a bottom horizontal edge, and the bottom horizontal edge is bent upward to form a side vertical edge connected to the clamping groove 11.

In this structure, the pressure plate 21 plays the main role of connection and filling support, and the setting of the flexible sleeve 24 enables the pressure plate 21 to form a soft connection with the connecting groove 12, ensuring that the connecting groove 12 has a very small deformation capacity. When the photovoltaic panel 3 is subjected to excessive positive and negative wind loads and snow loads, the force exerted on the upper clamping groove 11 will be quickly transmitted to the connecting groove 12, and the force will be unloaded through the buffering of the flexible sleeve 24. On the one hand, it can avoid local collapse of the connecting groove 12; on the other hand, it can prevent the clamping groove 11 from deformation. The structure is simple and ingenious.

The pressing plate 21 is pressed on the top of two adjacent steel frames 1 at the same time, and is suitable for the installation and connection of adjacent steel frame units.

[0106] Embodiment 9: Figures 17 to 19 The ninth embodiment of the solar photovoltaic panel support system of the present invention is shown, which is basically the same as the first embodiment, except that in this embodiment, the steel frame 1 is an open frame formed by bending a steel plate. The open frame is easier to form and has lower cost.

[0107] In this embodiment, the two broken edges of the open frame and the connecting groove 12 do not exceed the contour area of ​​the steel frame 1. In this structure, the connecting groove 12 is located within the contour area of ​​the steel frame 1, making the overall steel frame 1 more compact and slender, more beautiful and durable.

[0108] In this embodiment, the fastener 2 includes a pressure plate 21, a fastening bolt 22, a T-nut 23 and a flexible sleeve 24. The T-nut 23 is placed in the base 4, the pressure plate 21 is built in the flexible sleeve 24, one end of the flexible sleeve 24 is pressed into the connecting groove 12 and forms support for each groove edge thereof, the fastening bolt 22 is passed through the flexible sleeve 24 and the pressure plate 21 and is threadedly connected with the T-nut 23. When the fastening bolt 22 is tightened, the fastening bolt 22 drives the flexible sleeve 24 and the pressure plate 21 to press the connecting groove 12. In this structure, the pressure plate 21 plays the main role of connection and filling support, and the setting of the flexible sleeve 24 enables the pressure plate 21 to form a soft connection with the connecting groove 12, ensuring that the connecting groove 12 has a very small deformation capacity. When the photovoltaic panel 3 is subjected to excessive positive and negative wind loads and snow loads, the force exerted on the upper clamping groove 11 will be quickly transmitted to the connecting groove 12, and the force will be unloaded through the buffering of the flexible sleeve 24. On the one hand, it can avoid local collapse of the connecting groove 12; on the other hand, it can prevent the clamping groove 11 from deformation. The structure is simple and ingenious.

[0109] In this embodiment, the top groove edge of the clamping groove 11 is bent downward to form a broken edge, and the bottom groove edge of the connecting groove 12 is bent upward to form another broken edge. In this structure, the two broken edges are respectively placed on the clamping groove 11 and the connecting groove 12, and the structure is simple and practical.

[0110] In this embodiment, the fracture edge on the clamping groove 11 is located in the clamping groove 11 and is in close contact with the top groove edge of the clamping groove 11. This arrangement improves the strength of the top of the clamping groove 11.

[0111] In this embodiment, the fracture edge on the connecting groove 12 is located in the connecting groove 12 and is perpendicular to the bottom groove edge of the connecting groove 12. This arrangement is equivalent to forming a retaining edge structure on the fracture edge to prevent the flexible sleeve 24 and the pressing plate 21 from retreating.

[0112] In this embodiment, a reinforcing platform 121 is formed on the bottom edge of the connecting groove 12 and is recessed into the connecting groove 12. The provision of the reinforcing platform 121 improves the strength of the steel frame 1.

[0113] In this embodiment, the flexible sleeve 24 and the pressing plate 21 are both configured as a U-shaped plate, which is simultaneously pressed into the connection grooves 12 of two adjacent steel frames 1 and supports each groove edge thereof, and the fastening bolt 22 is passed through the middle position of the flexible sleeve 24 and the pressing plate 21 and is threadedly connected with the T-shaped nut 23. The flexible sleeve 24 and the pressing plate 21 are simultaneously pressed into the connection grooves 12 of the two adjacent steel frames 1 and form a filling-type support for the connection grooves 12 of the two adjacent steel frames 1, which is suitable for the installation and connection of adjacent steel frame units.

[0114] Embodiment 10: Fig. 20 The tenth embodiment of the solar photovoltaic panel support system of the present invention is shown, which is basically the same as the embodiment 9, except that: in this embodiment, the flexible sleeve 24 and the pressing plate 21 are both set as a U-shaped plate, one end of which is pressed into the connection groove 12 and supports each groove edge, and the other end is pressed onto the base 4, and the fastening bolt 22 is passed through the flexible sleeve 24 and the pressing plate 21 and is threadedly connected with the T-nut 23.
