[0001] The present invention belongs to the technical field of photovoltaic brackets, and in particular relates to a large-span flexible photovoltaic bracket connection structure. Background Art

Photovoltaic brackets are brackets used to place, install and fix photovoltaic components in photovoltaic power generation systems. With the rapid development of photovoltaic power station construction, photovoltaic brackets in complex terrains such as mountains and pools usually use traditional flexible photovoltaic brackets.

[0017] 2. When encountering strong winds, the photovoltaic panels are affected by the wind and drive the suspension cables to swing. When the wind stops, the second spring uses its own resilience and the damping retraction of the damping telescopic rod to drive the suspension cables to slowly reset and straighten, thereby reducing the swing of the suspension cables caused by wind and improving the wind resistance of the device.

[0018] 3. When the suspension cable pulls the telescopic end of the damping telescopic rod due to swinging, the suspension cable will slide frictionally with the guide hole. The ball bearing can change the sliding friction into rolling friction, thereby reducing friction damage and increasing the service life of the device.

[0019] 4. When the suspension cable is stretched due to the weight of the photovoltaic panel for a long time, the hydraulic rod drives the second mounting frame to slide into the slide groove of the first mounting frame, so as to straighten the suspension cable that has become loose due to the stretching, so as to prevent the photovoltaic panel from swinging sharply due to the wind force caused by the loose suspension cable;

[0020] 5. When the second mounting bracket moves, the screw rod will be driven to move synchronously through the connecting block. At this time, the nut screwed on the outside of the screw rod will be separated from the guide sleeve. After the position of the second mounting bracket is determined, tighten the nut. The nut against the guide sleeve can prevent the photovoltaic panel from pulling the second mounting bracket suddenly down through the suspension cable when the hydraulic rod fails, thereby ensuring the reliability of the device.

[0036] A method for using a large-span flexible photovoltaic support connection structure:

[0037] Step 1: After connecting the fixing holes on the first base 11 and the cable 12 with the embedded screws on the ground and fixing them with nuts, place the photovoltaic panel 2 evenly on the suspension cable 38, and make the suspension cable 38 between the first clamping block 21 and the second clamping block 211, and use the bolt 212 to penetrate the through hole of the second clamping block 211 and connect it with the threaded hole of the first clamping block 21, so that the first clamping block 21 and the second clamping block 211 clamp and fix the suspension cable 38, thereby completing the fixation of the photovoltaic panel 2, and increase the friction force of the first clamping block 21 and the second clamping block 211 on the suspension cable 38 through the anti-slip pad 22, and at the same time, when the bolt 212 is tightened, the round head pin 214 is driven by the first spring 213 to be inserted into the positioning hole of the bolt 212, so as to prevent the bolt 212 from loosening, thereby improving the installation stability of the photovoltaic panel 2.

[0038] Step 2: When encountering strong winds, the photovoltaic panel 2 will shake due to the wind, which will drive the suspension cable 38 to swing. Since the connecting sleeve 37 on the outside of the suspension cable 38 is connected to the telescopic end of the damping telescopic rod 33 through the spring buckle 36, when the suspension cable 38 swings, it will pull the telescopic end of the damping telescopic rod 33. At this time, the telescopic end of the damping telescopic rod 33 drives the connecting ring 34 to squeeze the second spring 35 due to the pulling. When the wind stops, the second spring 35 uses its own resilience and the damping retractability of the damping telescopic rod 33 to drive the suspension cable 38 to perform chronic reset and straightening, thereby reducing the swing of the suspension cable 38 caused by the wind, thereby improving the wind resistance of the device. When the suspension cable 38 pulls the telescopic end of the damping telescopic rod 33 due to the swing, the suspension cable 38 will slide frictionally with the guide hole, and the sliding friction can be changed to rolling friction through the ball 39, thereby reducing friction damage and increasing the service life of the device.

[0039] Step three: When the cable 38 is stretched due to the weight of the photovoltaic panel 2 for a long time, the second mounting frame 32 is driven by the hydraulic rod 31 to slide into the slide groove of the first mounting frame 3, so that the cable 38 that has become loose due to the stretching can be straightened again, so as to prevent the photovoltaic panel 2 from swinging greatly due to the wind force caused by the looseness of the cable 38. When the second mounting frame 32 moves, it will drive the screw rod 41 to move synchronously through the connecting block 4. At this time, the nut 43 screwed on the outer side of the screw rod 41 will separate from the guide sleeve 42. When the position of the second mounting frame 32 is determined, the nut 43 is tightened. The nut 43 is against the guide sleeve 42 to prevent the photovoltaic panel 2 from suddenly falling through the cable 38 to pull the second mounting frame 32 after the hydraulic rod 31 fails, so as to ensure the reliability of the device.
