Description

Technical Field

[0001] The present invention relates to the technical field of floating offshore photovoltaic technology, and in particular to a floating offshore photovoltaic platform structure with liftable photovoltaic panels. Background Art

[0002] Photovoltaic (PV), short for solar photovoltaic power generation, is a novel power generation system that utilizes the photovoltaic effect of semiconductor materials in solar cells to convert solar radiation into electricity. Compared to ground-based PV power plants, floating PV plants avoid land restrictions and also protect the aquatic ecosystem, such as by reducing evaporation and inhibiting algae growth. They can also be integrated with aquaculture, truly achieving comprehensive resource utilization.

[0003] Photovoltaic platforms typically incorporate hydraulic mechanisms to elevate the panels, facilitating cleaning and maintenance. However, existing technologies employ a single-panel adjustment method, employing a hydraulic cylinder at the base of each panel to control the height of each panel. Due to the unique offshore environment, the piston seals of the hydraulic cylinders can age over time, leading to saltwater infiltration, contamination of the hydraulic oil, and electrochemical corrosion of metal components (such as tubing joints), causing leaks. In such cases, hydraulic cylinder failures require repair or replacement. However, existing single-panel adjustment methods utilize a large number of hydraulic cylinders, resulting in a high number of potential problems and increased maintenance costs.

[0021] The connecting mechanism includes a driving assembly, a transmission assembly, and a guide rod 18 and a guide rod 22. The guide rod 18 is fixedly installed inside the cross seat 7 near the end of the connecting groove 8. Both ends of the outside of the guide rod 18 are slidably sleeved with a sliding plate 19. The two sliding plates 19 are fixedly installed on the side close to each other. The two blocking blocks 20 respectively cooperate with their corresponding slots 10.

[0023] The transmission assembly includes a fixed shaft 30, a transmission rod 31 is rotatably sleeved on the outside of the fixed shaft 30, and two sliders 32 are rotatably installed at both ends of the transmission rod 31. The two sliders 32 are slidably installed in the interior of their respective corresponding slide grooves 26.

[0024] Two symmetrically distributed limit plugs 33 are fixedly installed on the side of multiple installation platforms 1 close to the installation plate 3, and two symmetrically distributed limit slots 34 are provided on the side of multiple installation platforms 1 away from the limit plugs 33 and the side of the installation plate 3 close to the installation platform 1. The multiple limit plugs 33 respectively cooperate with their corresponding limit slots 34.

[0025] The front and back ends of the multiple mounting platforms 1 close to the mounting plate 3 are all rotatably mounted with connecting plates 35, and the ends of the multiple connecting plates 35 close to the mounting plate 3 are threadedly connected with fixing bolts 36. The front and back ends of the multiple mounting platforms 1 away from the connecting plates 35 and the front and back ends of the mounting plates 3 close to the mounting platform 1 are all provided with fixing holes 37, and the multiple fixing holes 37 respectively cooperate with their corresponding fixing bolts 36.

[0026] Working principle: When in use, first connect one of the mounting platforms 1 with the mounting plate 3. The operation steps are as follows: the photovoltaic panel 6 above the mounting platform 1 is initially located at the bottom under the action of its own gravity, and the slider 15 on its top is located at the rightmost end inside the slide groove 16. The plug-in column 9 on the telescopic shaft side of the hydraulic cylinder 5 corresponds to the connecting groove 8 on the side of the cross seat 7 above the mounting platform 1, and the two limiting plugs 33 on one side of the mounting platform 1 correspond to the two limiting slots 34 on one side of the mounting plate 3. Push the mounting platform 1 toward the mounting plate 3, so that the plug-in column 9 on the telescopic shaft side of the hydraulic cylinder 5 is inserted into the corresponding connecting groove 8, and the two limiting plugs 33 on one side of the mounting platform 1 are inserted into the two limiting slots 34 on one side of the mounting plate 3. Then rotate the two connecting plates 35 respectively. , make the two fixing bolts 36 correspond to the fixing holes 37 at one end of the front and back of the mounting plate 3 respectively, and finally rotate the two fixing bolts 36 and insert them into the two fixing holes 37 respectively, thereby completing the connection between the mounting platform 1 and the mounting plate 3. When the plug-in column 9 on one side of the telescopic shaft of the hydraulic cylinder 5 is inserted into the corresponding connecting groove 8, the two clamping blocks 20 are first forced to move away from each other, and then drive the two sliding plates 19 to move away from each other outside the guide rod 18, while squeezing the two springs 21. When the plug-in column 9 on one side of the hydraulic cylinder 5 is fully inserted into the corresponding connecting groove 8, the two clamping blocks 20 at this time are clamped into the corresponding clamping groove 10 under the action of the two springs 21, and the connection between the hydraulic cylinder 5 and its adjacent cross seat 7 is completed.

[0027] Subsequently, the connection between two adjacent mounting platforms 1 is achieved through the two limiting plugs 33 and two limiting slots 34 on both sides of the mounting platform 1. The fixation between the two adjacent mounting platforms 1 is then achieved through the connecting plate 35, fixing bolts 36 and fixing holes 37. When connecting two adjacent cross seats 7, the same as described in the above steps, it is only necessary to insert the plug-in column 9 on one side of a cross seat 7 into the connecting groove 8 on the side of the adjacent cross seat 7. The number of required mounting platforms 1 can be adjusted according to needs, thereby adjusting the number of photovoltaic panels 6. By starting the hydraulic cylinder 5, its telescopic shaft pushes multiple cross seats 7 to move to the left at the same time, thereby driving multiple sliders 15 to slide to the left along their corresponding slide grooves 16. The top ends of the multiple adjustment rods 14 lift their corresponding lifting brackets 13, the lengths of the multiple telescopic rods 11 and the multiple telescopic rods 2 12 are extended, and the heights of the multiple photovoltaic panels 6 are synchronously increased. By splicing multiple mounting platforms 1 and mounting plates 3, and connecting multiple cross seats 7 to the telescopic shaft of the hydraulic cylinder 5, multiple photovoltaic panels 6 can be raised and lowered synchronously as the telescopic shaft of the hydraulic cylinder 5 extends and retracts, achieving the effect of one hydraulic cylinder 5 controlling the height of multiple photovoltaic panels 6 at the same time, replacing the existing technology in which each photovoltaic panel 6 requires a hydraulic cylinder 5 to adjust. The number of hydraulic cylinders 5 that may have problems later is also relatively small, greatly reducing maintenance costs.

[0028] When replacing one of the mounting platforms 1 or the photovoltaic panel 6 above it, the operation process is as follows: rotate the threaded rod 27 above the mounting platform 1, and the pushing plate 28 moves backward along the two guide rods 3 29. At this time, the right end of the pushing plate 28 acts on the sliding plate 19 behind it, and the sliding plate 19 at the rear moves backward, and drives the corresponding slider 2 32 to slide inside the corresponding slide groove 26. The transmission rod 31 on the right rotates around the corresponding fixed axis 30 and pushes the sliding plate 19 in front to move forward. The two sliding plates 19 move away from each other synchronously along the guide rod 2 22 and squeeze the two springs 1 21. The two blocks 20 are simultaneously disengaged from their corresponding slots 10, thereby separating the cross seat 7 from the adjacent plug-in column 9 on the right. At the same time, the left end of the pushing plate 28 acts on the sliding plate 2 23 behind it. Under the action of the left end transmission component The two sliding plates 23 slide away from each other along the guide rods 22 and squeeze the two springs 25. The two sliding plates 23 drive the two top blocks 24 to move respectively. The two top blocks 24 act on their corresponding blocking blocks 20, so that the two blocking blocks 20 on one side of the adjacent cross seat 7 are disengaged from the two blocking grooves 10 on the left side of the cross seat 7, thereby separating the cross seat 7 from the adjacent connecting groove 8 on the left side. At this point, the cross seat 7 is not connected to the cross seats 7 on both sides. Subsequently, the two fixing bolts 36 at one end of the bottom of the mounting platform 1 are rotated to disengage the two fixing bolts 36 from the corresponding fixing holes 37, and then the mounting platforms 1 on both sides are pushed to make a certain distance between the mounting platform 1 and the mounting platforms 1 on both sides. The mounting platform can then be taken out, so that the mounting platform 1 or the photovoltaic panel 6 on its top can be replaced or repaired separately.
