Description

Technical Field

[0001] This application relates to the field of anchoring devices for floating photovoltaic systems, and more particularly to an adaptive tension anchoring device for a floating photovoltaic support. Background Technology

[0002] Floating photovoltaic (PV) systems are power generation systems that fix photovoltaic modules to floating PV supports and anchor them to the seabed. The anchoring system of floating PV systems typically includes anchor posts fixed to the seabed, with wire rope clamps fixed to the bottom of the anchor posts. Cables are fixed to the wire rope clamps, and the end of the cable away from the wire rope clamps is fixed to the floating PV support. Usually, the length of the cable has some slack, allowing the cable to adapt to changes in water level during high and low tides.

[0003] However, in environments with large water depths and significant water level differences during high and low tides, this fixing method results in excessive cable slack during low tide, which cannot effectively secure the floating photovoltaic support. This leads to a large displacement of the floating photovoltaic support, and in order to accommodate this displacement, the number of floating photovoltaic supports installed per unit space is relatively small, ultimately resulting in a small capacity for the floating photovoltaic power station. Summary of the Invention

Limiting springs are fixedly connected to both the upper and lower ends of the drive rod. The length direction of the limiting springs is set along the length direction of the tension rod. The end of the limiting spring away from the drive rod is fixedly connected to the side of the floating plate near the anchor column. The limiting spring limits the drive rod, so that the drive rod is close to the guide tube. A vertical rod is fixedly connected to the bottom of the drive rod. A sliding hole is provided on the float plate for the vertical rod to be inserted and moved. The length direction of the sliding hole is set along the length direction of the tension rod. The lower end of the vertical rod passes through the top cylinder wall of the fixed end of the tension rod and is fixedly connected to the moving end of the tension rod.

The length of the cables can adapt to the rising water level, keeping the cable tension within a set range. When the water level falls, the water level measuring component and the transmission component work together to gradually retract the cables, keeping the cable length can adapt to the falling water level, keeping the cable tension within a set range. This effectively fixes the floating photovoltaic support, reduces the displacement of the floating photovoltaic support, allows more floating photovoltaic supports to be installed in a unit space, and increases the capacity of the floating photovoltaic power station. By setting up floats, tension rods, drive rods, limit springs, vertical rods, and hinge rods, the release and retraction of the cable can be controlled; By setting up a support plate, lead screw, base plate, and motor, when encountering severe weather, high wave intensity, and situations where the water level rises and falls rapidly in a short period of time, the operator can manually control the full release of the cable to prevent the transmission components from failing to release the cable in time, thus reducing the occurrence of cable breakage.

[0023] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0024] This application discloses an adaptive tension anchoring device for a floating photovoltaic support. It includes a floating base 1, on which multiple cables 2 are fixedly connected, evenly distributed along the circumferential edge of the floating base 1. Anchor posts 3, corresponding one-to-one with the cables 2, are installed and fixed on the seabed. The height of the anchor posts 3 is greater than the maximum height above sea level. A cover 4 is provided on the side of the anchor posts 3 near the floating base 1. The top of the cover 4 is sealed off, and multiple through holes for seawater flow are opened on the circumferential sidewalls of the cover 4. The height of the cover 4 is greater than the maximum water level fluctuation. Multiple support rods 41 are fixedly connected to the side of the cover 4 near the anchor posts 3, evenly arranged along the height direction of the cover 4. The end of each support rod 41 away from the cover 4 is fixedly connected to the sidewall of the anchor posts 3.

[0025] The side wall of the cover 4 is provided with a strip hole 42 that is compatible with the cable 2. The length direction of the strip hole 42 is set along the height direction of the cover 4. The cable 2 is passed through the strip hole 42. The end of the cable 2 away from the floating base 1 is downward and inclined towards the anchor post 3. A wire rope clamp is fixedly connected to the bottom of the side wall of the anchor post 3. The end of the cable 2 away from the floating base 1 is fixed to the wire rope clamp.

[0026] The enclosure 4 is equipped with a water level measuring component 5 for monitoring changes in water level. The water level measuring component 5 includes a horizontally arranged float 51. Multiple sliders 511 are fixedly connected to the side wall of the float 51. In this embodiment, there are two sliders 511, which are symmetrically distributed around the float 51. The inner side wall of the enclosure 4 is provided with a groove 43 corresponding to each slider 511. The length direction of the groove 43 is set along the height direction of the enclosure 4. Each slider 511 is slidably inserted into the corresponding groove 43. The slider 511 cooperates with the groove 43 to enable the float 51 to move along the height direction of the enclosure 4. The float 51 cannot rotate within the enclosure 4 when it moves. In order to make the float 51 move more smoothly, a ball bearing 52 is rotatably connected to the side wall of the slider 511 near the enclosure 4. The ball bearing 52 rolls with the groove wall corresponding to the groove 43.

[0027] A guide tube 53 for guiding the cable 2 is fixedly connected to the float plate 51. The upper end of the guide tube 53 is inclined towards the floating base 1. An oblique hole 512 is opened through the float plate 51, and the inclination angle of the oblique hole 512 is the same as that of the guide tube 53. The guide tube 53 and the oblique hole 512 are connected. The cable 2 passes through the guide tube 53 and the oblique hole 512. The guide tube 53 cooperates with the float plate 51 to guide the cable 2, so that the section of the cable 2 above the float plate 51 is horizontal and the section of the cable 2 below the float plate 51 is inclined. In order to reduce the rapid wear of the cable 2 caused by the cooperation between the cable 2 and the guide tube 53, an arc plate 54 is fixedly connected to the bottom of the guide tube 53 near the floating base 1. The arc plate 54 gradually bends downward along the side near the floating base 1, and the cable 2 overlaps the arc plate 54.

[0028] A tensioning ring 6 is looped and fixed on the cable 2. The tensioning ring 6 is located below and close to the float 51. A tensioning rod 7 is fixedly connected to the side wall of the tensioning ring 6 near the anchor post 3. The tensioning rod 7 is horizontally set and its length is telescopic. The length direction of the tensioning rod 7 is set along the line connecting the tensioning ring 6 and the anchor post 3. The tensioning rod 7 includes a crossbar 71 fixedly connected to the tensioning ring 6. A sleeve 72 is slidably sleeved on the side of the crossbar 71 away from the tensioning ring 6. A connecting plate 73 is fixedly connected to the top of the side wall of the sleeve 72. The top of the connecting plate 73 is fixedly connected to the lower surface of the float 51.

[0029] The housing 4 is also equipped with a transmission assembly 8 that adjusts the length of the tension rod 7 according to the height position of the float 51. The float 51 cooperates with the transmission assembly 8, the tension rod 7 and the tension ring 6 to keep the tension of the cable 2 within the set range. The transmission assembly 8 includes a drive rod 81 that is slidably connected to the upper surface of the float 51. The drive rod 81 is located on the side of the guide tube 53 near the anchor post 3. The length direction of the drive rod 81 is set along the height direction of the housing 4, and the sliding direction of the drive rod 81 is set along the length direction of the tension rod 7.

[0030] The drive rod 81 includes a bottom cylinder 811 with its opening facing downwards. A transmission rod 812 is slidably inserted into the lower end of the bottom cylinder 811. A connecting spring 813 is fixedly connected to the upper end face of the transmission rod 812. The upper end of the connecting spring 813 is fixedly connected to the inner top surface of the bottom cylinder 811. The bottom cylinder 811, the connecting spring 813, and the transmission rod 812 cooperate to make the length of the drive rod 81 extendable and elastic.

[0031] A T-shaped connecting block 82 is fixedly connected to the upper end face of the bottom cylinder 811. A connecting groove 44 adapted to the connecting block 82 is opened on the inner top surface of the cover 4. The length direction of the connecting groove 44 is set along the length direction of the tensioning rod 7. The connecting block 82 is slidably inserted into the connecting groove 44. A horizontally set transmission plate 83 is fixedly connected to the lower end face of the transmission rod 812. A mating groove 84 adapted to the transmission plate 83 is fixedly connected to the upper surface of the float 51. The two ends of the mating groove 84 are sealed. The transmission plate 83 is slidably inserted into the mating groove 84; the connecting block 82 and the transmission plate 83 are both fixedly connected to the side wall near the anchor column 3. The end of the upper limiting spring 85 near the anchor column 3 is fixedly connected to the groove wall of the corresponding end of the connecting groove 44, and the end of the lower limiting spring 85 near the anchor column 3 is fixedly connected to the corresponding end face of the mating groove 84. The limiting spring 85 limits the drive rod 81, so that the drive rod 81 is close to the guide tube 53.

[0032] A hinge rod 86 is hinged to the upper surface of the transmission plate 83. The end of the hinge rod 86 away from the transmission plate 83 is upward and inclined away from the anchor post 3. The end of the hinge rod 86 away from the transmission plate 83 is hinged to the top of the inner wall of the cover 4. A vertically arranged vertical rod 87 is fixedly connected to the middle of the lower surface of the transmission plate 83. The vertical rod 87 passes through the bottom wall of the mating groove 84 and is slidably inserted into the mating groove 84. A sliding hole 513 for the vertical rod 87 to move is opened on the float plate 51. The length direction of the sliding hole 513 is set along the length direction of the tension rod 7. The vertical rod 87 is inserted into the sliding hole 513. The lower end of the vertical rod 87 passes through the cylinder wall of the sleeve 72 and is slidably inserted into the sleeve 72. The lower end of the vertical rod 87 is fixedly connected to the end of the cross bar 71 near the anchor post 3.

[0033] As the water level rises, the water surface moves upward and pushes the float 51 upward. The movement of the float 51 drives the mating tank 84, the transmission plate 83, and the transmission rod 812 upward. As the transmission rod 812 moves upward, it compresses the connecting spring 813. The transmission plate 83 drives the lower end of the hinge rod 86 upward, causing the lower end of the hinge rod 86 to rotate towards the anchor post 3. At the same time, it pushes the transmission plate 83 and the drive rod 81 towards the anchor post 3 and compresses the limit spring 85. The movement of the transmission plate 83 drives the vertical rod 87, the horizontal rod 71, and the tensioning ring 6 towards the anchor post 3, thereby gradually releasing the cable 2. The length of the cable 2 can adapt to the rising water level, keeping the tension of the cable 2 within the set range.

[0034] As the water level drops, the connecting spring 813 recovers its deformation and pushes the transmission plate 83, the adapter tank, and the float 51 downward, bringing the float 51 into contact with the water surface. Simultaneously, the transmission plate 83 moves downward, causing the lower end of the hinge rod 86 to rotate and reset, moving it closer to the floating base 1. At the same time, the limiting spring 85 recovers its deformation. The limiting spring 85, in conjunction with the hinge rod 86, causes the drive rod 81 and the transmission plate 83 to move away from the anchor post 3. The transmission plate 83 drives the vertical rod 87, the horizontal rod 71, and the tension ring 6 to move away from the anchor post 3, thus gradually retracting the cable 2. This ensures that the length of the cable 2 adapts to the continuously decreasing water level, and the tension of the cable 2 remains within a set range. This effectively secures the floating photovoltaic support, improving its stability, reducing its displacement, allowing for more floating photovoltaic supports to be installed within a given space, and increasing the capacity of the floating photovoltaic power station.

[0035] When encountering severe weather, the waves are strong, causing the water level to rise and fall rapidly in a short period of time. To prevent the cable 2 from breaking due to the transmission component 8 failing to release it in time, the cover 4 is also equipped with a control component 9 for manually controlling the release of the cable 2. The control component 9 includes a support plate 91 set below the float 51. The support plate 91 is horizontally set and located on the side of the guide tube 53 near the floating base 1. The support plate 91 is slidably connected to the cover 4. Multiple T-shaped guide blocks 92 are fixedly connected to the side wall of the support plate 91 near the floating base 1. The inner side wall of the cover 4 is provided with guide grooves 45 corresponding to the guide blocks 92. The length direction of the guide grooves 45 is set along the height direction of the cover 4. Each guide block 92 is slidably inserted into the corresponding guide groove 45. The guide block 92 cooperates with the guide groove 45 to make the support plate 91 slide along the height direction of the cover 4.

[0036] A horizontal base plate 93 is fixedly connected to the bottom of the inner wall of the cover 4. The base plate 93 is located directly below the support plate 91. A lead screw 94 is provided between the upper surface of the base plate 93 and the inner top surface of the cover 4. The length of the lead screw 94 is set along the height direction of the cover 4. The upper end of the lead screw 94 is rotatably connected to the inner top surface of the cover 4, and the lower end of the lead screw 94 is rotatably connected to the upper surface of the base plate 93. The lead screw 94 passes through the support plate 91 and is threadedly engaged with the support plate 91. The lead screw 94 passes through the float plate 51 and is slidably inserted into the float plate 51. A motor 95 for driving the lead screw 94 to rotate is also installed and fixed on the top surface of the cover 4.

[0037] In the initial state, the support plate 91 is located at the bottom of the cover 4. Before severe weather, the operator controls the motor 95 to work, causing the lead screw 94 to rotate. The lead screw 94 cooperates with the guide block 92 and the guide groove 45 to drive the support plate 91 to move upward. When the support plate 91 moves to contact the float 51, the support plate 91 pushes the float 51, the mating groove 84, the transmission plate 83 and the transmission rod 812 to move upward, and compresses the connecting spring 813. At the same time, the transmission plate 83 drives the hinge rod 86 to rotate. When the hinge rod 86 rotates, it pushes the drive rod 81, the vertical rod 87, the horizontal rod 71 and the tension ring 6 to move towards the anchor column 3, and compresses the limit spring 85. While the tension ring 6 moves, the cable 2 is released.

[0038] After the motor 95 has been running for a period of time, the connecting spring 813 is compressed to its limit, and the support plate 91, float plate 51, drive rod 81, crossbar 71 and tension ring 6 move to their limit positions. The operator then turns off the motor 95. At this time, the length of the cable 2 is its maximum usable length, which can adapt to the sudden rise in water level, thereby reducing the occurrence of cable 2 breakage. In actual use, during the process of setting up the adaptive tension anchoring device, the operator can select a suitable length of tension rod 7 according to the actual water level difference of the ebb and flow of the tide, so that the usable length of the cable 2 meets the requirements of the actual situation.

[0039] After the severe weather ends, the operator controls the motor 95 to operate, causing the output shaft of the motor 95 to rotate in the opposite direction. This causes the lead screw 94 to drive the support plate 91 to move downwards and reset. At the same time, the connecting spring 813 and the limit spring 85 both return to their original deformation, causing the float 51, drive rod 81, tension rod 7, and tension ring 6 to move and reset. When the float 51 moves to contact the water surface, the drive rod 81, tension rod 7, and tension ring 6 all stop moving. After the motor 95 has been operating for a period of time, the support plate 91 returns to its initial position. At this time, the operator turns off the motor 95.

[0040] The implementation principle of the adaptive tension anchoring device for a floating photovoltaic support in this application embodiment is as follows: When the water level rises, the water pushes the float 51 upward. At the same time, the float 51, the drive rod 81, and the transmission plate 83 cooperate to move the crossbar 71 and the tension ring 6 towards the anchoring column 3, thereby gradually releasing the cable 2 to adapt to the continuously rising water level. When the water level drops, the limiting spring 85 gradually recovers its deformation and pushes the transmission rod 812 and the float 51 downward, so that the float 51 is always in contact with the water surface. At the same time, the float 51, the drive rod 81, and the transmission plate 83 cooperate to move the crossbar 71 and the tension ring 6 away from the anchoring column 3, thereby retracting the cable 2 to adapt to the continuously falling water level, and the tension of the cable 2 is always kept within the set range.

[0041] Before severe weather arrives, the operator controls motor 95 to operate. After motor 95 operates for a period of time, connecting spring 813 is compressed to its limit, and cable 2 is released to its maximum length. At this time, the operator turns off motor 95. After severe weather ends, the operator controls motor 95 to operate, causing the output shaft of motor 95 to rotate in the opposite direction. This causes lead screw 94 to drive support plate 91 to move downwards and reset. At the same time, float plate 51 also moves downwards and resets. When float plate 51 moves to contact the water surface, tension ring 6 stops moving. After motor 95 operates for a period of time, support plate 91 returns to its initial position, and the operator turns off motor 95.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
