Description

A purlin structure for a photovoltaic module support Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a purlin structure for a photovoltaic module support. Background Technology

[0002] The function of photovoltaic (PV) panel mounting brackets is to fix and support PV modules. Common PV panel mounting bracket arrangements are two rows, one above the other, with a gap of approximately 10-30mm between the rows and columns. A common bracket scheme is a "four-purlin arrangement," where adjacent purlins meet end-to-end, and a purlin connector is installed at the point of contact to connect the two adjacent purlins together.

[0003] Regarding the existing patent number: CN201821392866.1, patent name: Purlin assembly for photovoltaic panel mounting bracket, it adopts a method of connecting the first purlin and the second purlin to each other, which makes the purlin assembly easy to install and has strong rigidity, making it suitable for pilot testing in large-span applications. However, during assembly, it is necessary to produce two different sizes of purlins, resulting in high production costs. Furthermore, when the connection length is long, the top surface of the purlin will become increasingly higher or lower, which is not convenient for installing photovoltaic modules.

[0004] Therefore, since it does not meet the existing requirements, we propose a purlin structure for photovoltaic module support. Summary of the Invention

[0005] The purpose of this utility model is to provide a purlin structure for a photovoltaic module support, so as to solve the problems mentioned in the background art, such as the need to produce two different sizes of purlins during assembly, resulting in high production costs, and the fact that when the connection length is long, the top surface of the purlin will become higher or lower, which is inconvenient for installing photovoltaic modules.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a purlin structure for a photovoltaic module support, comprising a purlin, one end of which is provided with a filling end, and the other end of which is provided with a plug-in end. The plug-in ends of the purlins are all movably inserted into the top of the filling end of another purlin. The bottom end of each plug-in end is provided with a bottom groove, and the filling end is movably engaged into the interior of the bottom groove.

[0007] Preferably, the purlin has multiple side holes on both sides, the side holes between the filling end and the plug end overlap each other, and the filling end and the plug end are connected by a bolt inserted into the internal thread of the side hole.

[0008] Preferably, the bottom end of the purlin is provided with multiple bottom holes, and a fixed platform is movably installed at the bottom end of each purlin. A threaded rod is fixedly installed at the top of the fixed platform, and the threaded rod is movably inserted into the interior of one of the bottom holes.

[0009] Preferably, a clamping ring is fixedly installed at the bottom end of the fixed platform, and a main beam is provided inside the clamping ring.

[0010] Preferably, a nut is movably installed between the threaded rod and the bottom hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the cooperation of the filling end and the plug-in end, allows the device to be used by inserting the plug-in end into the top of the filling end on the surface of another purlin, so that multiple purlins can be combined and connected with each other. This allows the device to be adapted to different photovoltaic module sizes for splicing and combination. At the same time, the device can be easily combined and extended, and the top surface of the purlin will not become higher or lower during the combination and extension.

[0013] 2. This utility model, through the cooperation of the bottom hole and the fixing platform, allows the fixing platform to be installed inside the bottom hole at different positions according to the position of the main beam during use. This makes the device adaptable to the installation position of the fixing platform when the main beam is in different positions, which facilitates the use of the device.

[0014] 3. By setting the side holes, this utility model allows the two purlins to be connected by bolts, thereby improving the connection strength between the two purlins and preventing them from separating. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please refer to Figures 1 to 4. One embodiment of this utility model is provided: a purlin structure for a photovoltaic module support, including a purlin 1, one end of the purlin 1 is provided with a filling end 2, and the other end of the purlin 1 is provided with a plug-in end 3. The plug-in end 3 of the purlin 1 is movably inserted into the top of the filling end 2 of another purlin 1. The bottom end of the plug-in end 3 is provided with a bottom groove 10, and the filling end 2 is movably inserted into the bottom groove 10.

[0022] By combining the filling end 2 and the plug end 3, the device can be used by inserting the plug end 3 into the top of the filling end 2 on the surface of another purlin 1, so that multiple purlins 1 can be connected to each other. This allows the device to be adapted to different photovoltaic module sizes for splicing and combination. At the same time, the device can be easily combined and extended, and the top surface of the purlin 1 will not become higher or lower during the combination and extension.

[0023] The purlin 1 has multiple side holes 4 on both sides. The side holes 4 between the filling end 2 and the insertion end 3 overlap each other. The filling end 2 and the insertion end 3 are connected by bolts inserted into the internal threads of the side holes 4.

[0024] The side hole 4 allows the two purlins 1 to be connected by bolts, thereby increasing the strength of the connection between the two purlins 1 and preventing them from separating.

[0025] The bottom end of the purlin 1 is provided with multiple bottom holes 5. A fixed platform 6 is movably installed at the bottom end of each purlin 1. A threaded rod 7 is fixedly installed at the top of the fixed platform 6. The threaded rod 7 is movably inserted into the interior of one of the bottom holes 5.

[0026] By using the bottom hole 5 and the fixed platform 6 together, the fixed platform 6 can be installed inside the bottom hole 5 at different positions according to the position of the main beam 9 during use. This allows the device to be adapted to the installation position of the fixed platform 6 when the main beam 9 is in different positions, making the device convenient to use.

[0027] A clamping ring 8 is fixedly installed at the bottom of the fixed platform 6, and a main beam 9 is provided inside the clamping ring 8.

[0028] Nuts are movably installed between the threaded rod 7 and the bottom hole 5.

[0029] When in use, the purlin structure of the photovoltaic module support can be connected by inserting the plug end 3 into the top of the filling end 2 on the surface of another purlin 1, so that multiple purlins 1 can be combined and connected with each other. This allows the device to be adapted to different photovoltaic module sizes for splicing and combination. At the same time, the device can be easily combined and extended, and the top surface of the purlin 1 will not become higher or lower during the combination and extension.

[0030] Depending on the position of the main beam 9, the fixing platform 6 can be installed inside the bottom hole 5 at different positions, so that the device can be adapted to the installation position of the fixing platform 6 when the main beam 9 is in different positions, which facilitates the use of the device.

[0031] The side hole 4 allows the two purlins 1 to be connected by bolts, thereby increasing the strength of the connection between the two purlins 1 and preventing them from separating.
