Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a photovoltaic support column node connection structure. Background Technology

[0002] In photovoltaic (PV) power generation, the installation of PV panels requires PV support brackets. These brackets are typically height-adjustable to accommodate different installation sites. For example, a Chinese patent document discloses an adjustable PV support column node (application number: CN202022514918.1). The upper steel pipe column is height-adjustable. Bolts are used to fix the upper steel pipe column through longitudinal oval holes, and nuts are then used to secure it. However, the square steel pipe supporting the PV panel needs to withstand significant pressure. Using a single bolt to support the upper steel pipe column, secured only by nuts at both ends, and with the nuts tightened, the pressure between the nuts and the lower steel pipe column only provides temporary support. This cannot stably support the PV panel. If the nuts loosen, the bolt can move within the longitudinal oval holes, affecting the supporting function of the upper steel pipe column.

[0003] Therefore, we propose a photovoltaic support column node connection structure. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic support column node connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic support column node connection structure, comprising a first square steel pipe and a second square steel pipe. The first square steel pipe has a first sliding groove on both its left and right outer walls, a positioning port on the inner wall of the first sliding groove, a first positioning block within the positioning port, an internal hexagonal bolt in the center of the first positioning block, a through groove on the first positioning block, and a push rod within the through groove. The second square steel pipe has a first fixing port on its right side surface and a second fixing port on its left side surface, a second positioning block within the second fixing port, a threaded hole in the center of the second positioning block, second sliding grooves at the center of both ends of the first positioning block, sliders within the second sliding grooves, and a locking slot on the inner wall of the positioning port.

[0006] Preferably, the second square steel pipe is installed inside the first square steel pipe, and the second square steel pipe and the first square steel pipe are slidably connected.

[0007] Preferably, the hexagon socket bolt passes through the first positioning block, the second square steel pipe and connects to the threaded hole, and both the first positioning block and the second square steel pipe are provided with through holes that mate with the hexagon socket bolt.

[0008] Preferably, both the second slide and the bayonet are inclined.

[0009] Preferably, the push rod is connected to the slider, and the push rod is slidably connected to the through groove.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-6This utility model provides a technical solution: a photovoltaic support column node connection structure, including a first square steel pipe 1 and a second square steel pipe 2. The first square steel pipe 1 has first sliding grooves 3 on both its left and right outer walls. The inner wall of the first sliding grooves 3 has a positioning port 4, and a first positioning block 5 is installed inside the positioning port 4. An internal hexagon bolt 6 is installed in the center of the first positioning block 5. A through groove 7 is provided on the first positioning block 5, and a push rod 8 is installed inside the through groove 7. The right side surface of the second square steel pipe 2 has a first fixing port 9, and the left side surface of the second square steel pipe 2 has a second fixing port 10. The first positioning block 5 has a second positioning block 11 with a threaded hole 111 in the middle. The first positioning block 5 has second sliding grooves 12 at both ends, with sliders 13 inside the second sliding grooves 12. A locking slot 14 is provided on the inner wall of the positioning port 4. The height of the second square steel pipe 2 is adjusted by using a tool (e.g., an Allen wrench) to rotate the Allen bolt 6. The Allen bolt 6 rotates and engages with the threaded hole 111, allowing for disassembly. After disassembly, the Allen bolt 6 pushes the push rod 8, which moves the slider 13 into the second sliding groove 12. 13. Disengage from the bayonet 14, loosen the fixing of the first positioning block 5, allowing the first positioning block 5 to move out of the first fixing port 9 and the positioning port 4, and the second positioning block 11 to move out of the second fixing port 10. The second square steel pipe 2 can then move up and down within the first square steel pipe 1. After moving the second square steel pipe 2 to the required height, place the first positioning block 5 into the positioning port 4 provided on the side of the first square steel pipe 1, and simultaneously move one end of the first positioning block 5 into the first fixing port 9. The second positioning block 11 is installed in the same manner as the first positioning block 5, with one end of the second positioning block 11 installed into the second fixing port 10. Inside, the hexagonal socket bolt 6 passes through the first fixing block 5 and the second square steel pipe 2 and connects to the threaded hole 111, and the hexagonal socket bolt 6 is tightened. The first positioning block 5 and the second positioning block 11 provide support and fixation for the second square steel pipe 2, providing stable support for the second square steel pipe 2. After the first positioning block 5 and the second positioning block 11 are installed, the push rod 8 is released, and the slider 13 slides under the action of gravity. The slider 13 locks into the latch 14 to fix the first positioning block 5 and the second positioning block 11, further strengthening the support and fixation of the first square steel pipe 2 by the first positioning block 5 and the second positioning block 11.

[0015] The second square steel pipe 2 is installed inside the first square steel pipe 1. The second square steel pipe 2 and the first square steel pipe 1 are slidably connected. The second square steel pipe 2 moves up and down inside the first square steel pipe 1 to adjust the height of the second square steel pipe 2, thereby arbitrarily adjusting the height of the photovoltaic support column. The socket head cap screw 6 passes through the first positioning block 5 and the second square steel pipe 2 and connects to the threaded hole 111. Both the first positioning block 5 and the second square steel pipe 2 are provided with through holes that mate with the socket head cap screw 6. The socket head cap screw 6 fixes the first positioning block 5 and the second positioning block 11 by mates with the threaded hole 111. The second slide 12 and the bayonet 14 are both inclined. The slider 13 slides under the action of gravity. After the slider 13 slides, it locks the bayonet 14 to fix the first positioning block 5 and the second positioning block 11. The push rod 8 is connected to the slider 13, and the push rod 8 is slidably connected to the through groove 7. The movement of the push rod 8 drives the slider 13 to move. The slider 13 has a locking slot 14 at the moving point, which facilitates the disassembly of the first positioning block 5 and the second positioning block 11.

[0016] Working principle: Rotating the hex bolt 6 causes it to engage with the threaded hole 111, allowing for disassembly. After disassembly, the hex bolt 6 pushes the push rod 8, which in turn moves the slider 13 into the second groove 12. The slider 13 disengages from the latch 14, releasing the first positioning block 5 and causing it to move out of the first fixing port 9 and the positioning port 4. The second positioning block 11 moves out of the second fixing port 10, allowing the second square steel pipe 2 to move up and down within the first square steel pipe 1. After moving the second square steel pipe 2 to the desired height, the first positioning block 5 is placed in the positioning port 4 on the side of the first square steel pipe 1, while simultaneously moving one end of the first positioning block 5 to the first fixing port 9. Inside, the second positioning block 11 is installed in the same way as the first positioning block 5. One end of the second positioning block 11 is installed into the second fixing port 10, so that the internal hex bolt 6 passes through the first fixing block 5 and the second square steel pipe 2 and connects with the threaded hole 111. The internal hex bolt 6 is then tightened. The first positioning block 5 and the second positioning block 11 provide support and fixation for the second square steel pipe 2, providing stable support for the second square steel pipe 2. After the first positioning block 5 and the second positioning block 11 are installed, the push rod 8 is released, and the slider 13 slides under the action of gravity. The slider 13 locks into the locking slot 14 to fix the first positioning block 5 and the second positioning block 11, further strengthening the support and fixation of the first square steel pipe 2 by the first positioning block 5 and the second positioning block 11.
