Description

Technical Field

[0001] This utility model relates to photovoltaic brackets, and more particularly to a hole-free fixing structure for carbon steel photovoltaic bracket purlins. Background Technology

[0002] Traditional carbon steel photovoltaic brackets use C-shaped steel purlins, which require fixing the longitudinal beams to the purlins through holes. Different longitudinal beam spans and purlin break points are designed according to different environmental parameters and design conditions. Different purlin lengths and different relative positions to the longitudinal beams result in the need to open different installation holes. This design is extremely complex and cumbersome in design, production and on-site installation, which is not conducive to the application and promotion of photovoltaic brackets.

[0003] In traditional carbon steel photovoltaic brackets, photovoltaic modules are directly fixed to C-shaped steel purlins with bolts. Therefore, the purlins need to be customized according to different module sizes and positions, and the fixing hole positions of the purlins and modules need to be designed. This not only makes the research and development design and factory production steps complicated, but also makes it easy to make mistakes.

[0004] The C-shaped steel purlins of traditional carbon steel photovoltaic brackets typically have their openings angled upwards, which can easily cause water to accumulate in the grooves during rainy weather, accelerating the local corrosion rate of the materials. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a fixing structure for carbon steel photovoltaic bracket purlins that eliminates the need to drill holes in the purlins.

[0006] To solve the above-mentioned technical problems, this utility model provides a carbon steel photovoltaic bracket purlin fixing structure without drilling, including: fixing blocks, fixing connectors and C-shaped steel purlins, as well as longitudinal beams or photovoltaic modules;

[0007] The fixing block has a connecting portion that is fixed to the longitudinal beam or photovoltaic module by a fixing connector, and a pressing portion that extends into the C-shaped steel purlin; when the connecting portion is fixedly connected to the longitudinal beam or photovoltaic module, the pressing portion presses and fixes the C-shaped steel purlin to the longitudinal beam or photovoltaic module.

[0008] In a preferred embodiment, the opening of the C-shaped steel purlin faces the connecting portion.

[0009] In a preferred embodiment: the crimping portion is U-shaped, and its opening direction is located on the side of the crimping portion away from the longitudinal beam or photovoltaic module.

[0010] In a preferred embodiment: the connecting portion includes a protrusion connected to the edge of the U-shaped opening of the crimping portion, and a flat surface that conforms to the longitudinal beam or photovoltaic module, wherein the protrusion and the flat surface are transitioned by a bevel.

[0011] In a preferred embodiment: the fixing connector is a bolt and a nut, and the connecting part and the longitudinal beam or photovoltaic module are provided with clearance openings at corresponding positions. One end of the bolt passes through the clearance opening and is fixedly connected to the nut.

[0012] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0013] This utility model provides a hole-free fixing structure for carbon steel photovoltaic bracket purlins. In the installation of longitudinal beams and purlins, bolts are not required. The purlins can be directly fixed using a fixing block installation scheme. During production, only the shape of the purlins needs to be produced, and no holes need to be drilled in the purlins.

[0014] This utility model provides a hole-free fixing structure for carbon steel photovoltaic bracket purlins. In the installation of photovoltaic modules and purlins, it is not necessary to drill holes in the purlins to install bolts. Fixing blocks can be used to directly fix the photovoltaic modules to the purlins, and then the photovoltaic modules are fixed to the fixing blocks with bolts. During production, only the shape of the purlins needs to be produced, and there is no need to drill holes.

[0015] This utility model provides a hole-free fixing structure for carbon steel photovoltaic bracket purlins. During installation, the fixing block can fix the C-shaped steel purlin opening directly at an angle downwards. Since no holes are made, rainwater cannot flow into the groove of the C-shaped steel purlin from the holes. Attached Figure Description

[0020] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0021] Example 1

[0022] refer to Figure 1 and Figure 3 This embodiment provides a non-drilling fixing structure for carbon steel photovoltaic bracket purlins, including: fixing block 1, fixing connector 2, C-shaped steel purlin 3, and longitudinal beam 4;

[0023] The fixing block 1 has a connecting part 11 that is fixed to the longitudinal beam 4 by a fixing connector 2, and a pressing part 12 that extends into the C-shaped steel purlin 3; when the connecting part 11 is fixedly connected to the longitudinal beam 4, the pressing part 12 presses and fixes the C-shaped steel purlin 3 to the longitudinal beam 4.

[0024] In this embodiment, the opening of the C-shaped steel purlin 3 faces the connecting portion 11. Thus, during installation, the fixing block 1 can fix the opening of the C-shaped steel purlin 3 directly downwards at an angle, and because there are no holes, rainwater cannot flow into the groove of the C-shaped steel purlin 3 from the holes.

[0025] In this embodiment, the crimping portion 12 is U-shaped, and its opening direction is located on the side of the crimping portion 12 away from the longitudinal beam 4 or the photovoltaic module, so as to ensure the contact area between the crimping portion 12 and the C-shaped steel purlin 3.

[0026] Furthermore, the connecting portion 11 includes a protrusion 121 connected to the edge of the U-shaped opening of the crimping portion 12, and a flat surface 122 that conforms to the longitudinal beam 4 or the photovoltaic module. The protrusion 121 and the flat surface 122 are transitioned by a slope 123. The fixing connector 2 is a bolt and a nut. The protrusion 121 and the longitudinal beam 4 or the photovoltaic module are provided with clearance openings at corresponding positions. One end of the bolt passes through the clearance opening and is fixedly connected to the nut.

[0027] Further reference Figure 2 In addition to fixing the C-shaped steel purlin 3 to the longitudinal beam 4, the aforementioned fixing structure can also fix the C-shaped steel purlin 3 to the photovoltaic module.

[0028] Example 2

[0029] refer to Figure 1 In this embodiment, the inclined surface 123 and the plane 122 of the connecting part 11 in embodiment 1 are eliminated. The connecting part 11 extends directly from the edge of the protrusion 121 downward to the vertical plate 121 that abuts against the longitudinal beam 4 or the surface of the photovoltaic module.

Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
