Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1
The present embodiment provides a guide rail for a photovoltaic module, as shown in fig. 1, the guide rail 10 includes a bottom 12 and two side walls 11 disposed opposite to each other on two sides of the bottom 12, and two side walls 11 and the bottom 12 form a guide rail opening 13;
each of the side walls 11 is provided with a clamping portion 14 protruding toward the rail opening 13 near the rail opening 13, the clamping portion 14 including an extension wall 141 and a connection wall 142 connecting the extension wall 141 and the side wall 11, the extension wall 141 extending from an end of the side wall 11 and being bent toward the inside of the rail 10. The rail 10 is intended to accommodate a fixture 30 of a photovoltaic module (described in detail below), while the rail opening 13 is able to expand outwards, which facilitates the installation of the fixture 30, thanks to the fact that the clamping portion 14 is able to undergo a certain elastic deformation with respect to the bottom 12.
The bottom 12 is provided with a bolt slot 121.
The rail 10 further comprises a reinforcement wall 15 arranged inside the rail connecting the side wall 11 and the bottom 12. Thanks to the reinforcing wall 15, the connection of the side wall 11 to the bottom 12 is more secure and the elastic deformation of the side wall 11 will be limited.
Unlike the prior art photovoltaic module rails, the presence of the bolt slots 121 avoids drilling holes in the bottom of the rails to install the screw means. Moreover, the bolt groove 121 in the embodiment penetrates through the whole photovoltaic guide rail, so that the installation position of the bolt is not limited by the bolt perforation, the installation is more flexible, and the installation time and the installation cost of the photovoltaic module are saved. With equal dimensions and thickness, the cross-sectional moment of inertia and the cross-sectional modulus of the guide rail according to the utility model are greater compared to the U-shaped guide rail of the prior art.
Example two
On the basis of the first embodiment, this embodiment further includes the following features: the bolt groove 121 comprises a bolt groove bottom wall formed by protruding the bottom 12 towards the interior of the guide rail 10, and a bolt groove opening 122 is arranged in the direction of deviating from the bolt groove bottom wall of the bolt groove 121.
This design allows the rail to accommodate the full volume of the bolt slot 121, making the rail 10 more compact.
Example III
On the basis of the first embodiment, this embodiment further includes the following features: inside the guide rail 10 two reinforcement walls 15 are provided, each reinforcement wall 15 connecting the side wall 11 and the bottom wall of the bolt slot.
In this embodiment, the guide rail 10 includes two reinforcing walls 15 therein, and the two reinforcing walls 15 are symmetrical in structure in this embodiment to provide sufficient strength to the side wall 11. Moreover, thanks to the presence of the reinforcing wall 15, the outward elastic deformation of the side walls 11 is hindered, which allows the clamp 30 to be more firmly fixed inside the rail 10.
Example IV
On the basis of the first embodiment, this embodiment further includes the following features: the bolt slot opening 122 is provided with a bolt slot limiting protrusion 123 for limiting the bolt. As shown in fig. 3, the head of the bolt 20 can be fixed in the bolt groove 121 thanks to the bolt groove limiting protrusion 123. Such a design avoids perforation at the bottom of the rail 10. It can be appreciated that such a bolt slot limiting protrusion 123 penetrates the entire length direction of the guide rail 10, so that the installation position of the bolt can be more flexible, the installation position of the bolt can be adjusted at any time, and thus the installation of the photovoltaic module is more convenient.
Example five
On the basis of the first embodiment, this embodiment further includes the following features: an extension wall stopper protrusion 143 is formed on the extension wall 141 near the connection wall 142. The presence of the extension wall stop projection 143 can snap the clip 30 into the rail 10 without disengaging from the rail 10. Hereinafter, the present utility model will be described in detail. Preferably, the extension wall stopper protrusion 143 has a length of 1-5mm. Such a design enables stable clamping of the jig 30, and also enables easy removal of the jig 30 when the jig 30 is removed.
Example six
The extension wall 141 has an angular or cambered surface. As shown in fig. 1, the extension wall 141 has an angular number of 3 in this embodiment. As shown in fig. 2, the number of corners is 2. In other embodiments, the extension wall 141 may be a curved surface (not shown) without a corner. The shape of the extension wall 141 is related to the manufacturing method of the side wall 11, for example, the side wall is formed in a mold, and at this time, the shape of the extension wall 141 is related to the shape of the mold.
Example seven
On the basis of the first embodiment, this embodiment further includes the following features: the guide rail 10 is made of steel or an aluminum alloy, which are all materials commonly used in the art. The guide rail 10 made of steel has higher strength; while the guide rail 10 made of aluminum alloy is lighter and more suitable for installation on a building. Steel and aluminum alloys are also capable of undergoing elastic deformation while providing strength, and thus are ideal materials for manufacturing guide rails. Those skilled in the art can select the specific materials of the guide rail 10 according to actual needs.
Example eight
The present embodiment provides a fastening apparatus for a photovoltaic module, as shown in fig. 3, including a guide rail 10, a clamp 30, and a bolt 20 according to the present utility model. The fixture 30 may be a fixture commonly used in the art, such as an alamong clip, which is simple in shape and convenient to install, and thus is suitable for installation of a photovoltaic module. Thanks to the clamping portion 14, the body of the clamp 30 is fixed in the rail 10 through the rail opening 13 of the rail 10. And the presence of the extension wall stopper protrusions 143 can clamp the clip 30 in the guide rail 10 without being separated from the guide rail 10.
When the clamp 30 is installed, the two sides 10 of the rail are elastically displaced toward the outside of the rail by means of a specific tool, such as a pliers, to expand the rail opening 13, and at this time, the clamp 30 can be inserted into the rail 10 through the expanded rail opening 13. After the clamp 30 is placed in place, as shown in fig. 3, the clamp can be removed, at which point the two side walls 11 of the rail are restored and the two sides of the clamp 30 are clamped, thereby securing the clamp 30 in the rail 10.
The fastening device according to the utility model is easy to install and to disassemble and is therefore particularly suitable for installation of photovoltaic modules on buildings.
