[0001] This utility model belongs to the field of booster station technology, specifically relating to an anchoring device for a photovoltaic power generation booster station. Background Technology
[0002] The photovoltaic power generation booster station is the core power conversion and transmission unit of a floating photovoltaic power station. Its stable operation directly depends on a reliable anchoring device. The anchoring device needs to work with the anchor cable and the underwater anchor head to fix the floating body carrying the booster station equipment in the designated water area, so as to prevent the floating body from shifting or capsizing due to wind, waves and water flow. It is a key structure to ensure the power generation efficiency and operational safety of the power station.
[0003] In practical applications, existing photovoltaic power generation substation anchoring devices are prone to continuous friction at the long-term contact points between the anchor cable and the limiting ring due to the swaying of the floating body caused by wind and waves. Traditional devices lack wear protection mechanisms, and the increased wear of the anchor cable will shorten its service life, which not only increases maintenance costs but may also lead to the risk of floating body instability due to anchor cable failure. Utility Model Content

The same anchor cable is wound around the two take-up and release rollers. An anchoring head is set below the circular float. Limiting rings are set on the top of the anchoring head and on one side of the two take-up and release rollers. The two upper limiting rings are fixedly connected to the top of the circular float, and the lower limiting ring is fixedly connected to the top of the anchoring head. The anchor cable passes through the three limiting rings in sequence. Mounting plates are provided on the sides of the two take-up and release rollers that are far apart from each other, and mounting shafts are rotatably mounted on the sides of the two mounting plates that are close to each other.

[0006] Preferably, the gear transmission assembly includes a gearbox and a fixed box connected to each other. One end of the mounting shaft away from the first motor passes through the inner wall of the fixed box and is fixedly sleeved with a first bevel gear. Rotary shafts are rotatably mounted on the inner walls of both sides of the gearbox. End face gears are fixedly sleeved on the rotating shafts. One end of the rotating shaft extends into the fixed box and is fixedly mounted with a second bevel gear. The second bevel gear meshes with the first bevel gear.
[0007] Preferably, the drive assembly includes a second motor, which is fixedly mounted on the side of one of the gearboxes and the top of the circular float.

At the same time, with the cooperation of a second motor, gear transmission assembly and rotating ring, it can drive the two take-up and release rollers of the same anchoring mechanism to rotate in opposite directions, realizing the switching of the connection position between the anchor cable and the limiting ring, effectively reducing the wear of the anchor cable during long-term use, and combining water level adaptability with component wear protection capability, thereby improving the overall stability and service life of the device.

Detailed Implementation
[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0017] like Figures 1-7 As shown, an anchoring device for a photovoltaic power generation booster station includes a circular float 1, with four anchoring mechanisms fixedly installed on the top of the circular float 1. The anchoring mechanism includes two take-up and release rollers 7 and a first motor 11. The same anchor cable 2 is wound around the two take-up and release rollers 7. An anchoring head 3 is provided below the circular float 1. Limiting rings 8 are provided on the top of the anchoring head 3 and on one side of the two take-up and release rollers 7. The two upper limiting rings 8 are fixedly connected to the top of the circular float 1, and the lower limiting ring 8 is fixedly connected to the top of the anchoring head 3. The anchor cable 2 passes through the three limiting rings 8 in sequence. Mounting plates 10 are provided on the sides of the two take-up and release rollers 7 that are far apart from each other, and mounting shafts 9 are rotatably mounted on the sides of the two mounting plates 10 that are close to each other. The two take-up and release rollers 7 are respectively fixedly sleeved on the two mounting shafts 9. One of the mounting shafts 9 passes through the mounting plate 10 and is fixedly connected to the output shaft of the first motor 11. The first motor 11 is fixedly mounted on the top of the circular float 1 and the side of the mounting plate 10. The other take-up and release roller 7 is equipped with a gear transmission assembly. The gear transmission assembly includes a gearbox 5 and a fixed box 6 connected to each other. One end of the mounting shaft 9, away from the first motor 11, passes through the inner wall of the fixed box 6 and is fixedly sleeved with a first bevel gear 14. Rotary shafts 12 are rotatably mounted on the inner walls of both sides of the gearbox 5. End face gears 15 are fixedly sleeved on the rotating shafts 12. One end of the rotating shaft 12 extends into the fixed box 6 and is fixedly mounted with a second bevel gear 13. The second bevel gear 13 meshes with the first bevel gear 14.
[0018] A drive assembly is mounted on the top of the circular float 1, and the drive assembly is connected to four gear transmission assemblies.
[0019] In use, multiple solar panels, batteries, transformers, and control boxes can be placed on the circular float 1. When in use, first fix the four anchor heads 3 to the bottom of the water, and then start the four first motors 11 to make the four take-up and release rollers 7 rotate. The rotation of the four take-up and release rollers 7 can retract the anchor cable 2, thereby tightening the anchor cable 2 and stabilizing the circular float 1. When the water level drops or rises, the anchor cable 2 can be retracted or released to meet the fixation requirements of different water levels.
[0020] The drive assembly includes a second motor 4, which is fixedly mounted on the side of one of the gearboxes 5 and the top of the circular float 1. The end of the rotating shaft 12 away from the second bevel gear 13 is fixedly connected to the output shaft of the second motor 4. A rotating ring 17 is rotatably mounted on the circular float 1. A plurality of evenly arranged meshing teeth 16 are fixedly mounted on the top of the rotating ring 17. The meshing teeth 16 are engaged with the end face gear 15 (meshing engagement). When the anchor cable 2 is fixed at the same water level for a long period of time, the water surface will fluctuate due to wind and waves, causing the connection between the anchor cable 2 and the limiting ring 8 to wear continuously. At this time, by simultaneously starting four first motors 11 and two second motors 4, the second motor 4 will start and cause the rotating shaft 12 to rotate. The rotating shaft 12 will drive the end face gear 15 to rotate. The end face gear 15 will drive the rotating ring 17 to rotate through multiple meshing teeth 16. At the same time, the multiple meshing teeth 16 will drive the other three end face gears 15 to rotate, which will in turn cause the four second bevel gears 13 and the four first bevel gears 14 to rotate. The rotation of the four first bevel gears 14 will drive the four take-up and release rollers 7 to rotate. At the same time, the output shafts of the four first motors 11 will drive the other four take-up and release rollers 7 to rotate in the opposite direction, so that one take-up and release roller 7 will take up the anchor cable 2 and the other take-up and release roller 7 will release the anchor cable 2. This allows the connection between the anchor cable 2 and the limiting ring 8 to be replaced, reducing the wear of the anchor cable 2.
[0021] like Figure 4 As shown, an annular cavity 18 is formed at the top of the circular float 1, and a rotating ring 17 is rotatably installed inside the annular cavity 18. The annular cavity 18 is used to limit the movement of the rotating ring 17.
[0022] The inner top wall of the annular cavity 18 is provided with four clearance holes, which correspond to the positions of the four gearboxes 5. The four end face gears 15 pass through the four clearance holes respectively.
[0023] A cylinder 19 is fixedly installed at the bottom of the circular float 1. The cylinder structure disclosed in patent CN222432533U can be adopted.
[0024] like Figure 1 and Figure 2 As shown, the bottom limiting ring 8 is located in the middle of the two upper limiting rings 8. The advantage of this design is that it ensures that the forces on both ends of the anchor cable 2 are balanced.
[0025] like Figure 2 As shown, both ends of the anchor cable 2 are fixedly connected to two take-up and release rollers 7. The advantage of this arrangement is that when one take-up and release roller 7 rotates, the anchor cable 2 can be taken up or released; when the two take-up and release rollers 7 rotate in opposite directions, the connection position between the anchor cable 2 and the limiting ring 8 can be switched.
[0026] Working principle: In use, multiple solar panels, batteries, transformers and control boxes can be placed on the circular float 1. When in use, first fix the four anchor heads 3 to the bottom of the water, and then start the four first motors 11 to make the four take-up and release rollers 7 rotate. The rotation of the four take-up and release rollers 7 can retract the anchor cable 2, thereby tightening the anchor cable 2 and stabilizing the circular float 1. When the water level drops or rises, the anchor cable 2 can be retracted or released to meet the fixation requirements of different water levels. When the anchor cable 2 is fixed at the same water level for a long period of time, the water surface will fluctuate due to wind and waves, causing the connection between the anchor cable 2 and the limiting ring 8 to wear continuously. At this time, by simultaneously starting four first motors 11 and two second motors 4, the second motor 4 will start and cause the rotating shaft 12 to rotate. The rotating shaft 12 will drive the end face gear 15 to rotate. The end face gear 15 will drive the rotating ring 17 to rotate through multiple meshing teeth 16. At the same time, the multiple meshing teeth 16 will drive the other three end face gears 15 to rotate, which will in turn cause the four second bevel gears 13 and the four first bevel gears 14 to rotate. The rotation of the four first bevel gears 14 will drive the four take-up and release rollers 7 to rotate. At the same time, the output shafts of the four first motors 11 will drive the other four take-up and release rollers 7 to rotate in the opposite direction, so that one take-up and release roller 7 will take up the anchor cable 2 and the other take-up and release roller 7 will release the anchor cable 2. This allows the connection between the anchor cable 2 and the limiting ring 8 to be replaced, reducing the wear of the anchor cable 2.
