Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, and in particular to an end structure of a flexible photovoltaic support. Background Technology

[0002] Flexible photovoltaic (PV) support systems utilize flexible components such as steel wire ropes and cables as the main load-bearing and support structures. A stable cable net is formed through tensioning technology to install PV modules. For flexible PV support systems, the end structures are crucial for ensuring the stability and safety of the entire system. They need to be firmly anchored to the foundation and reliably connected to the load-bearing main cables and stable stay cables.

[0003] However, in existing technologies, the bottom of the flexible photovoltaic support structure is usually fixed to the pile foundation, and the top is fixed with clamp anchors to install the stay cables and main cables. This solution is not convenient for workers to install in complex mountainous terrain environments, and the clamp anchors are prone to detachment under the influence of severe weather, which can lead to structural damage to the entire system.

[0004] Therefore, there is an urgent need to propose a flexible photovoltaic support end structure to solve the above problems. Utility Model Content

[0032] This embodiment provides a flexible photovoltaic support end structure. The end column body of the flexible photovoltaic support end structure is installed by hinge, and the inclined cable is tensioned and fixed by a second compression anchor and suspended to the top of the end column body. This not only solves the problems of inconvenient installation for workers and safety of high-altitude operations, but also avoids the risk of the clamp anchor coming off the anchor.

[0033] Specifically, such as Figures 1 to 4 As shown, the flexible photovoltaic support end structure includes a cable-stayed assembly 100, a cable assembly 200, and an end post assembly 300. The cable-stayed assembly 100 includes a cable-stayed base 110 and a first compression anchor 120, with the cable-stayed base 110 fixed to the ground. The cable assembly 200 includes a cable 210, one end of which is installed on the cable-stayed base 110 via the first compression anchor 120.

The end post base 310 is fixed to the ground, the bottom of the end post body 320 is hinged to the end post base 310, and the top is provided with an opening slot. The second compression anchor 330 is sleeved on the other end of the cable 210, and the cable 210 passes through the opening slot and hangs on the end post body 320, so that the second compression anchor 330 abuts against the side of the end post body 320 away from the cable-stayed base 110.

[0034] Based on the above design, the cable assembly 100 includes a cable base 110 and a first compression anchor 120. The cable assembly 200 includes a cable 210. One end of the cable 210 is installed on the cable base 110 through the first compression anchor 120. The cable 210 is tensioned and fixed by the first compression anchor 120, resulting in high cable strength and good performance. The end column assembly 300 includes an end column base 310, an end column body 320, and a second compression anchor 330. The bottom of the end column body 320 is hinged to the end column base 310, and the top is provided with an opening slot. The second compression anchor 330 is sleeved on the other end of the cable 210. The cable 210 passes through the opening slot and is hung on the end column body 320, so that the second compression anchor 330 abuts against the end column body 320. In actual installation, first install the end column base 310, then lay the end column body 320 flat and install it to the end column base 310 using hinge bolts 410. Then rotate and straighten the end column body 320, and install pins 420 to fix the end column body 320. At the same time, first install the second compression anchor 330 on the ground, and then suspend it into the opening slot at the top of the end column body 320. This can solve the problems of inconvenient installation for workers and safety of high-altitude operations, and also avoid the risk of the clamp anchor coming off the anchor.

[0035] Optionally, the end column body 320 can be made of either square or round tubing, depending on the requirements.

[0036] Optionally, continue as follows Figure 2As shown, the cable-stayed assembly 100 also includes a cable-stayed pile foundation 130, and a cable-stayed base 110 is fixed to the cable-stayed pile foundation 130. The cable-stayed base 110 is fixed to the ground through the cable-stayed pile foundation 130, which provides good stability.

[0037] Specifically, the inclined base 110 is fixed to the inclined pile foundation 130 by multiple bolts, which makes disassembly convenient.

[0038] Similarly, continue as follows Figure 3 As shown, the end column assembly 300 also includes an end column pile foundation 340, and the end column base 310 is fixed to the end column pile foundation 340. The end column base 310 is fixed to the ground through the end column pile foundation 340, which has good stability.

[0039] In this embodiment, the bottom of the end column body 320 is hinged and fixed to the end column base 310 by hinge bolts 410 and pins 420. Specifically, the end column base 310 includes a lower base 312 and an upper base 311. The first base plate of the lower base 312 is fixed to the end column pile foundation 340 by bolts, and the second base plate of the upper base 311 is fixed to the bottom of the end column body 320. Two first connecting plates are arranged opposite to each other on the first base plate, and a second connecting plate is arranged on the second base plate. The second connecting plate is sandwiched between the two first connecting plates. The hinge bolts 410 pass through and connect the first connecting plates and the second connecting plates to realize the hinged connection between the upper base 311 and the lower base 312. After the end column body 320 is rotated from a horizontal position to a vertical position, the pins 420 pass through the first connecting plates and the second connecting plates to fix the upper base 311 and the lower base 312.

[0040] Optionally, the side wall of the end column base 310 is provided with reinforcing ribs. In this embodiment, the reinforcing ribs are located on the outer side wall of the first connecting plate, connecting the first base plate and the first connecting plate, and preventing the first connecting plate from bending and deforming to both sides.

The limiting hole is located on the side of the opening slot away from the inclined base 110. The end column assembly 300 also includes a limiting bushing 350. The limiting bushing 350 is sleeved on the inclined cable 210 and locked in the limiting hole to prevent the inclined cable 210 from running off.

[0042] It should be noted that the limiting bushing 350 can also be replaced by a square hole part.

[0043] In this embodiment, there are two opening slots. The stay cables 210 and the stay components 100 correspond one-to-one with the opening slots. That is, one end of each of the two stay cables 210 is fixed to an end column body 320, and the other end of each of the two stay cables 210 is fixed by two sets of stay components 100 respectively.

[0044] Furthermore, the cable assembly 200 also includes a main cable 220. A first hole is provided between the two opening slots of the end column body 320. The main cable 220 passes through the first hole and is tensioned and fixed by the third compression anchor 230, which is safe and cost-effective. Moreover, the main cable 220 is located between the two inclined cables 210, which provides good stability.

[0045] Furthermore, a support sleeve 240 is also fitted onto the main cable 220, located between the first hole and the third compression anchor 230. The support sleeve 240 serves two purposes: firstly, it allows for a certain length of the main cable 220 to be used after maintenance and disassembly, ensuring sufficient length and avoiding the increased cost of replacing the main cable 220; secondly, it facilitates tensioning operations by the tensioning machine.

[0046] Optionally, continue as follows Figure 2 As shown, the cable-stayed assembly 100 also includes a U-bolt 140 and a connecting sleeve 150. A second hole is provided on the cable-stayed base 110. The U-bolt 140 passes through the second hole, hooking its bottom onto the cable-stayed base 110. The connecting sleeve 150 is fitted onto the open end of the U-bolt 140. The cable-stayed cable 210 passes through the connecting sleeve 150, and a first compression anchor 120 abuts against the side of the connecting sleeve 150 facing the cable-stayed base 110. That is, a rocker arm structure is formed by passing the U-bolt 140 through the second hole, and then the connecting sleeve 150 passes through the U-bolt 140. The cable-stayed cable 210 is installed via the first compression anchor 120. This structure allows adjustment of the U-bolt 140's direction according to the terrain, and the cable-stayed cable 210 can be tightened using the nut on the connecting sleeve 150, ensuring the cable-stayed cable 210 is taut and taut after installation.

[0047] Optionally, continue as follows Figure 1 As shown, the flexible photovoltaic support end structure includes multiple end column assemblies 300. Two end column assemblies 300 form a group. Between two end column bodies 320 within the same group of end column assemblies 300, there is an end column crossbar 510 and an end column support rod 520. The two ends of the end column crossbar 510 are connected to the top side plates of the two end column bodies 320, respectively. One end of the end column support rod 520 is connected to the bottom side plate of one end column body 320, and the other end is connected to the top side plate of the other end column body 320. This structural design forms two triangular structures, simultaneously providing support and tension, making the overall structure more stable under stress.
