Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic brackets, and in particular to an anchorage wind-resistant system for a single-layer cable flexible photovoltaic bracket. Background Technology

[0002] Photovoltaic (PV) brackets, often referred to as the "skeleton" of a photovoltaic (PV) power plant, are specialized structural components designed and installed to support and secure PV modules within a PV power generation system. They are a crucial supporting structure in PV systems, and safety and ease of installation are their core requirements.

[0003] Traditional photovoltaic (PV) mounting systems, due to limitations in row spacing and clearance, can no longer fully meet diverse needs in terms of comprehensive land use and efficient utilization. Flexible PV mounting systems, with their high clearance, large span, and strong flexibility, are better suited to market demands.

[0004] However, flexible photovoltaic supports often experience large displacements under wind loads. In reciprocating wind load environments, the cable structure undergoes high-frequency and large-amplitude vibrations, leading to damage to photovoltaic modules and resulting in a series of economic losses. Utility Model Content

[0005] To address the issue mentioned above where flexible photovoltaic supports often experience significant displacement under wind loads, leading to high-frequency and large-amplitude vibrations in the cable structure during reciprocating wind loads and consequently damage to the photovoltaic modules, this invention provides an anchorage wind-resistant system for a single-layer cable flexible photovoltaic support.

[0006] This utility model provides an anchorage wind-resistant system for a single-layer cable-stayed flexible photovoltaic support, which adopts the following technical solution:

[0007] A wind-resistant anchoring system for a single-layer cable flexible photovoltaic support includes a central beam. Both the front and rear ends of the top of the central beam are connected to component cables. Multiple photovoltaic modules are laid on the top of the two sets of component cables. A wind-resistant cable is connected to the bottom of the central beam. A NUT clamp is sleeved in the middle of the wind-resistant cable. The wind-resistant cable is connected to a wind-resistant anchor pile through the NUT clamp.

[0008] By adopting the above technical solution, multiple photovoltaic modules are laid flat on two module cables. When the wind blows, under the action of wind suction load and horizontal wind load, the module cables can transfer the force to the wind-resistant anchor piles through the wind-resistant cables and NUT clamps. This effectively reduces the displacement of the module cables under wind load, enhances structural stability, avoids damage to the module cables due to large deformation, ensures the stable and healthy operation of flexible photovoltaic power stations, and promotes the long-term development of the flexible photovoltaic support industry.

[0009] Optionally, a longitudinal circular hole is provided on the side of the central beam near the component cable, and a U-shaped bolt is inserted inside the longitudinal circular hole. The inner top wall of the U-shaped bolt abuts against the top of the component cable, and the bottom of the U-shaped bolt extends out of the central beam and is screwed with a bolt.

[0010] By adopting the above technical solution, the component cable can be fixed to the top of the central beam.

[0011] Optionally, U-shaped pull rings are connected to both ends of the top of the wind-resistant cable and the middle beam. The front and rear ends of the inner walls of the two sets of U-shaped pull rings are welded with pads. A reserved hole is opened in the middle of the pad. A transverse circular hole is opened on the side of the middle beam near the wind-resistant cable. A shaft pin is inserted inside the reserved hole and the transverse circular hole.

[0012] By adopting the above technical solution, the wind-resistant cable can be fixedly connected to the bottom of the middle beam.

[0013] Optionally, the top of the wind-resistant anchor pile is connected to an ear plate, and the wind-resistant cable is connected to the top of the wind-resistant anchor pile through the round hole of the ear plate via a NUT clamp. The wind-resistant cable is V-shaped in general.

[0014] By adopting the above technical solution, the wind-resistant cable can be connected to the round hole on the ear plate through the NUT clamp, and the wind-resistant cable prestress can be applied through the NUT clamp.

[0015] Optionally, both ends of the wind-resistant cable pass through the interior of two sets of U-shaped pull rings and are equipped with multiple wire rope clamps, and a steel strand collar is provided at the connection between the wind-resistant cable and the U-shaped pull rings.

[0016] By adopting the above technical solution, the ends of the wind-resistant cable can be easily fixed by multiple wire rope clamps, and the setting of the steel strand loop makes it easy to connect the wind-resistant cable to the U-shaped pull ring.

[0017] Optionally, it also includes the ground, with three-quarters of the length of the wind-resistant anchor pile located below the ground and one-quarter of the length of the wind-resistant anchor pile located above the ground.

[0018] By adopting the above technical solution, most of the wind-resistant anchor piles are inserted below the ground, while the wind-resistant anchor piles located at the top of the ground are easy to connect with the wind-resistant cable.

[0019] Optionally, the wind-resistant anchor pile is an H-beam, the bottom of the wind-resistant anchor pile is spiked, and multiple pull-out steel plates are welded to both sides of the lower web of the wind-resistant anchor pile, and the multiple pull-out steel plates are inclined upwards.

[0020] By adopting the above technical solution, the spiked design facilitates the driving of wind-resistant anchor piles, and the combined arrangement of multiple pull-out steel plates increases the pull-out resistance of the wind-resistant anchor piles.

[0021] In summary, this utility model has at least one of the following beneficial effects:

[0022] By using a combination of wind-resistant cables, NUT clamps, and wind-resistant anchors, the structural loads generated by negative and horizontal winds can be transferred to the wind-resistant anchors through the wind-resistant cables and NUT clamps. This effectively reduces the vibration amplitude of the module cables under wind loads, prevents damage to the photovoltaic modules, enhances structural stability, and thus ensures the stable and healthy operation of the flexible photovoltaic power station.

[0023] By setting the bottom of the wind-resistant anchor piles into a spike shape, it is easier for the wind-resistant anchor piles to be inserted into the ground. At the same time, the pull-out resistance of the wind-resistant anchor piles is effectively improved by the combination of multiple pull-out steel plates. Attached Figure Description

A longitudinal circular hole is formed on the side of the central beam 2 near the component cable 7, and a U-bolt 21 passes through the interior of the longitudinal circular hole. The inner top wall of the U-bolt 21 abuts against the top of the component cable 7, and the bottom of the U-bolt 21 extends out of the central beam 2 and is screwed with a bolt. This allows the component cable 7 to be fixed to the top of the central beam 2.

[0035] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 4 and Figure 5 Multiple photovoltaic modules 1 are laid on the top of the two sets of component cables 7. Wind-resistant cables 3 are connected to the bottom of the central beam 2. U-shaped pull rings 22 are connected to the top two ends of the wind-resistant cables 3 and the central beam 2. The front and rear ends of the inner walls of the two sets of U-shaped pull rings 22 are welded with pads 24. A reserved hole is opened in the middle of the pad 24. A transverse circular hole is opened on the side of the central beam 2 near the wind-resistant cables 3. A shaft pin 23 is inserted into the reserved hole and the transverse circular hole. In this way, the wind-resistant cables 3 can be fixedly connected to the bottom of the central beam 2.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 6 The wind-resistant cable 3 has two ends that pass through the interior of two sets of U-shaped pull rings 22 and are equipped with multiple wire rope clamps 32.

The multiple wire rope clamps 32 facilitate the fixing of the ends of the wind-resistant cable 3, and the steel strand collar 31 facilitates the connection between the wind-resistant cable 3 and the U-shaped pull rings 22.

[0037] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 7 A NUT clamp 4 is sleeved in the middle of the wind-resistant cable 3. The wind-resistant cable 3 is fixedly connected to the wind-resistant anchor pile 5 through the NUT clamp 4. An ear plate 51 is fixedly connected to the top of the wind-resistant anchor pile 5. The wind-resistant cable 3 is connected to the top of the wind-resistant anchor pile 5 through the round hole of the ear plate 51 via the NUT clamp 4. The wind-resistant cable 3 is V-shaped. This allows the wind-resistant cable 3 to be connected to the round hole on the ear plate 51 through the NUT clamp 4, and thus the prestress of the wind-resistant cable 3 can be applied through the NUT clamp 4.

Multiple pull-out steel plates 52 are welded to both sides of the lower web of the wind-resistant anchor pile 5, all inclined upwards. The spiked design facilitates the driving of the wind-resistant anchor pile 5, and the coordinated arrangement of the multiple pull-out steel plates 52 increases the pull-out resistance of the wind-resistant anchor pile 5.

[0040] Working principle: In use, U-bolts 21 are inserted into the interior of the central beam 2 to fix two component cables 7 to the top of the central beam 2. Then, multiple photovoltaic modules 1 are laid flat on the two component cables 7.

The middle part of the wind-resistant cable 3 is connected to the top of the wind-resistant anchor pile 5 through NUT clamps 4. When the wind blows, under the action of wind suction load and horizontal wind load, the component cables 7 can transfer the force to the wind-resistant anchor pile 5 through the wind-resistant cable 3 and NUT clamps 4, effectively reducing the displacement of the component cables 7 under the action of wind load, enhancing structural stability, avoiding damage to the photovoltaic modules 1 due to large deformation, ensuring the stable and healthy operation of the flexible photovoltaic power station, and promoting the long-term development of the flexible photovoltaic support industry.
