Description

Technical Field

[0001] This invention relates to the field of floating photovoltaic anchoring technology, and in particular to a self-resetting anchoring device that can adapt to changes in water level and its usage method. Background Technology

[0002] As is well known, traditional photovoltaic power generation mainly relies on land resources, but faces problems such as land occupation, ecological impact, and rising surface temperatures. With the increasing demand for clean energy, floating photovoltaic power generation effectively solves the problem of scarce land resources by utilizing idle water space, while also possessing comprehensive advantages such as enhanced cooling efficiency, reduced evaporation, and protection of aquatic ecosystems.

[0003] Currently, in existing floating photovoltaic power stations under construction, the floating photovoltaic arrays need to be anchored to the seabed by steel cables. Due to the large fluctuations in water levels in some water areas, especially in areas with significant water level changes, the anchoring cables cannot be taut at lower water levels. This causes the floating photovoltaic arrays to move along the water surface, which can easily lead to collisions, deviation of the modules from the optimal tilt angle, and other adverse situations. This seriously affects the lifespan, yield, and maintenance difficulty of the photovoltaic arrays. Furthermore, the design must fully consider the cable design margin, which significantly increases the project cost.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a self-resetting anchoring device and its method of use that can adapt to changes in water level, making it suitable for areas with varying and significant water level changes, and ensuring effective and reliable anchoring throughout use.

[0006] According to the present invention, a self-resetting anchoring device capable of adapting to changes in water level is disposed between a floating array float and an anchoring foundation; the self-resetting anchoring device includes:

[0007] The first anchoring cable is configured to connect the anchor cable self-tensioning mechanism and the anchor cable synchronization mechanism;

[0008] The second anchoring cable is configured to connect the anchor cable synchronization mechanism to the floating array floats;

[0009] The anchor rope self-tensioning mechanism has a disc spring bolt assembly inside. The anchor rope self-tensioning mechanism is configured to be fixedly connected to the anchor foundation and can autonomously control the compression degree of the internal disc spring bolt assembly according to the water level changes in the area of ​​use.

[0010] The anchor rope synchronization mechanism is configured to simultaneously wind up the first anchor rope and the second anchor rope.

[0011] According to some embodiments of the present invention, the anchor rope self-tensioning mechanism includes an upper reset sleeve, a disc spring bolt assembly and a lower steel plate. The lower steel plate is fixedly connected to the anchor foundation by pre-embedded short bolts, and the anchor foundation is also fixedly connected to the anchor rope synchronization mechanism by pre-embedded long bolts.

[0012] The top of the upper reset sleeve is open and connected to the first anchoring cable. Its bottom has an opening and a cover. The lower steel plate has a central opening. The disc spring bolt assembly is placed inside the upper reset sleeve and is connected to the lower steel plate and the upper reset sleeve through the opening and the central opening, respectively.

[0013] According to some embodiments of the present invention, the disc spring bolt assembly includes a combined disc spring, a bolt, and a washer. The bottom end of the bolt is sequentially connected to the combined disc spring, the upper reset sleeve, and the lower steel plate, and the top end of the bolt is connected to the washer.

[0014] According to some embodiments of the present invention, the anchor rope synchronization mechanism includes a bearing, a large reel, and a small reel, the large reel and the small reel being synchronously rotated and connected to the bearing; one end of the first anchoring cable is connected to the top of the upper reset sleeve, and the other end of the first anchoring cable is wound around the small reel; one end of the second anchoring cable is wound around the large reel, and the other end of the second anchoring cable is connected to the floating array float.

[0015] According to some embodiments of the present invention, the first anchoring cable includes multiple first anchoring cables and one second anchoring cable; the second anchoring cable includes several third anchoring cables; one end of each of the multiple first anchoring cables is fixedly connected to the top periphery of the upper reset sleeve, and the other end of the multiple first anchoring cables is connected to one end of the second anchoring cable, and the other end of the second anchoring cable is wound around a corresponding small reel; each third anchoring cable is connected to the floating array float via a corresponding large reel.

[0016] A method of using a self-resetting anchoring device that can adapt to changes in water level, according to the present invention, includes:

[0017] In the initial state, the area in use is at the lowest water level, the combined disc spring assembly is in a pre-compressed state, the upper reset sleeve and the lower steel plate are in contact, and both the first anchoring cable and the second anchoring cable are in a taut state.

[0018] When the water level in the area rises, the anchor rope synchronization mechanism releases the second anchor rope and simultaneously retracts the first anchor rope. The upper reset sleeve disengages from the lower steel plate, and the combined disc spring assembly retracts further, so that both the first and second anchor ropes are in a taut state.

[0019] When the water level in the area drops, the combined disc spring releases its elastic potential energy, causing the upper reset sleeve to move closer to the lower steel plate. This causes the anchor rope synchronization mechanism to release the first anchoring cable and simultaneously retract the second anchoring cable, ensuring that both the first and second anchoring cables are taut.

[0020] According to the present invention, a self-resetting anchoring device and its method of use that can adapt to changes in water level can utilize the cooperation of an anchor rope self-tensioning mechanism and an anchor rope synchronization mechanism to ensure that the first and second anchoring cables remain taut even when the water level changes, thus reliably fixing the floating array to the anchoring foundation at all times. This effectively solves the adverse effects of water level changes on the anchoring of floating photovoltaic arrays. Furthermore, the present invention is also applicable to working environments with large water level variations, and has advantages such as convenient and quick construction, low cost, and high feasibility.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] The following is based on Figures 1-6 The self-resetting anchoring device that can adapt to changes in water level according to the present invention will be described in detail.

[0048] like Figure 1 As shown in the figure, an adaptive self-resetting anchoring device 1, provided by an embodiment of the present invention, is disposed between the floating array float 2 and the anchoring foundation 3. Please refer to... Figures 2 to 6The self-resetting anchoring device 1 includes a first anchoring cable 11, a second anchoring cable 12, an anchoring cable self-tensioning mechanism 13, and an anchoring cable synchronization mechanism 14. Specifically: the first anchoring cable 11 is configured to connect the anchoring cable self-tensioning mechanism 13 and the anchoring cable synchronization mechanism 14; the second anchoring cable 12 is configured to connect the anchoring cable synchronization mechanism 14 and the floating array float 2; the anchoring cable self-tensioning mechanism 13 has a disc spring bolt assembly 132 inside, and is configured to be fixedly connected to the anchoring foundation 3, and can autonomously control the compression degree of the internal disc spring bolt assembly 132 according to changes in the water level of the area; the anchoring cable synchronization mechanism 14 is configured to synchronously wind up the first anchoring cable 11 and the second anchoring cable 12.

[0049] In practical implementation, multiple anchoring foundations 3 can be set at the bottom of the floating array float 2, and a set of self-resetting anchoring devices 1 is set between each anchoring foundation 3 and the floating array float 2. In use, each set of self-resetting anchoring devices 1 can effectively anchor the floating array float 2 according to the water level. Under the coordinated action of the anchor rope self-tensioning mechanism 13 and the anchor rope synchronization mechanism 14, the first anchoring cable 11 and the second anchoring cable 12 are always kept taut during the anchoring process, avoiding adverse situations such as collisions caused by the floating array float 2 moving along the water surface, deviation of the components from the optimal tilt angle, and serious increase in cable design margin, thus ensuring a longer lifespan, higher yield, and easier operation and maintenance of the photovoltaic array.

[0050] Please refer to Figure 3 and Figure 4 The anchor rope self-tensioning mechanism 13 of this embodiment includes an upper reset sleeve 131, a disc spring bolt assembly 132, and a lower steel plate 133. The lower steel plate 133 is fixedly connected to the anchor foundation 3 by pre-embedded short bolts 1413. The anchor foundation 3 is also fixedly connected to the anchor rope synchronization mechanism 14 by pre-embedded long bolts 1412. The top of the upper reset sleeve 131 is open and connected to the first anchor cable 11. Its bottom has a cover 1311 with an opening 1311-1. The lower steel plate 133 is provided with a central opening 133-1. The disc spring bolt assembly 132 is placed inside the upper reset sleeve 131 and is connected to the lower steel plate 133 and the upper reset sleeve 131 through the opening 1311-1 and the central opening 133-1, respectively.

[0051] In practice, an upper steel plate 1411 is fixedly connected to each end of the bearing 141, and each upper steel plate 1411 is fixedly connected to the anchoring foundation 3 by several pre-embedded long bolts 1412.

[0052] Initially, the disc spring bolt assembly 132 is in a pre-compressed state, and the bottom of the upper reset sleeve 131 is tightly fitted with the lower steel plate 133. After the water level in the usage area rises, the net distance between the floating array float 2 and the anchor rope synchronization device increases, the disc spring bolt assembly 132 is further compressed, and the net distance between the upper reset sleeve 131 and the lower steel plate 133 gradually increases. After the water level in the usage area drops, the net distance between the floating array float 2 and the anchor rope synchronization device decreases, the disc spring bolt assembly 132 releases its stored elastic potential energy, and the net distance between the upper reset sleeve 131 and the lower steel plate 133 gradually decreases. Therefore, regardless of whether the water level rises or falls, the net distance variable caused by the water level change can be balanced by the anchor rope self-tensioning mechanism 13, so that the first anchor rope and the second anchor rope are always in a taut state, forming an effective and stable anchoring effect.

[0053] Please refer to Figure 4 The disc spring bolt assembly 132 of this embodiment includes a combined disc spring 1321, a bolt 1322, and a washer 1323. The bottom end of the bolt 1322 is sequentially connected to the combined disc spring 1321, the upper reset sleeve 131, and the lower steel plate 133, and the top end of the bolt 1322 is connected to the washer 1323. It can be understood that the two ends of the bolt 1322 are fastened together by nuts to form a single unit.

[0054] More specifically, the combined disc spring 1321 can be composed of multiple disc springs stacked and mated together. In use, the lower steel plate 133 and the upper reset sleeve 131 are tightly connected by the disc spring bolt assembly 132. The disc spring bolt assembly 132 applies an initial preload, which can put the combined disc spring 1321 in a compressed state.

[0055] The initial state of the self-resetting anchoring device 1 is the lowest water level in the area of ​​use. At this time, the combined disc spring 1321 is in a compressed state. Preferably, the initial compression displacement is 10% of the maximum compression displacement, which is used to better accumulate elastic potential energy and thus obtain better self-resetting capability.

[0056] Understandably, the design requires determining the highest and lowest water levels in the area in use, and ensuring that the combined disc spring 1321 does not reach its maximum compression displacement at the highest water level, and that the floating array float 2, under its own weight and the tension of the disc spring bolt assembly 132, will not cause the floating array float 2 to be completely submerged in the water, thereby causing the related aquatic devices of the floating array to be submerged in the water.

[0057] In the implementation of this invention, the disc springs and bolts 1322 used in the disc spring bolt assembly 132 have a high degree of industrialization, a complete industrial chain and standard specifications, low cost, and high construction feasibility. The combined disc springs 1321 used in the disc spring bolt assembly 132 have high flexibility, and their stiffness and deformation capacity can be flexibly designed by adjusting the number of overlaps and matings.

[0058] Please refer to Figure 3 The anchor rope synchronization mechanism 14 of this embodiment includes a bearing 141, a large reel 142 and a small reel 143. The large reel 142 and the small reel 143 are synchronously rotatably connected to the bearing 141. One end of the first anchoring cable 11 is connected to the top of the upper reset sleeve 131, and the other end of the first anchoring cable 11 is wound around the small reel 143. One end of the second anchoring cable 12 is wound around the large reel 142, and the other end of the second anchoring cable 12 is connected to the floating array float 2.

[0059] It is understood that the "size" in the large roll 142 and the small roll 143 does not have an absolute numerical meaning, but is a relative concept. That is, the radius of the large roll 142 is greater than the radius of the small roll 143. In specific implementation, the radius ratio of the large roll 142 and the small roll 143 can be adjusted according to actual needs, so that the self-resetting anchoring device 1 of this embodiment of the invention can be applied to areas with different water level changes and large water level changes. In particular, when the water level change in the area of ​​use is too large, by reasonably setting the radius ratio of the large roll 142 and the small roll 143, the waste caused by using too many combined disc springs 1321 can also be avoided.

[0060] The anchor rope synchronization device, in conjunction with the state changes of the anchor rope self-tensioning mechanism 13, enables real-time adjustment of the release and retraction of the first anchor rope 11 and the second anchor rope 12. Specifically, when the water level in the area of ​​use rises, the net distance between the floating array float 2 and the anchor rope synchronization device increases, the bearing 141 rotates in the forward direction, releasing the third anchor rope 121 and retracting the second anchor rope 112. The retraction of the second anchor rope 112 drives the upper reset sleeve 131 to move in the direction of the retraction of the second anchor rope 112, thereby further compressing the disc spring bolt assembly 132.

[0061] When the water level in the area drops, the net distance between the floating array float 2 and the anchor rope synchronization device decreases, the third anchor rope 121 begins to slack, and the upper reset sleeve 131 moves automatically along the elongation direction of the second anchor rope 112 under the action of the elastic potential energy of the disc spring bolt assembly 132, causing the second anchor rope 112 to be released, which in turn drives the bearing 141 to rotate in the opposite direction and retract the third anchor rope 121.

[0062] Please refer to Figure 1 , 34, 5, In this embodiment of the invention, the first anchoring cable 11 includes multiple first anchoring cables 111 and one second anchoring cable 112; the second anchoring cable 12 includes several third anchoring cables 121; one end of each of the multiple first anchoring cables 111 is fixedly connected to the top periphery of the upper reset sleeve 131, and the other end of each of the multiple first anchoring cables 111 is connected to one end of the second anchoring cable 112, and the other end of the second anchoring cable 112 is wound around a corresponding small reel 143; each third anchoring cable 121 is connected to the floating array float 2 through a corresponding large reel 142.

[0063] For example, there are four first anchor ropes 111, which are evenly arranged on the top of the upper reset sleeve 131; there are two third anchor ropes 121, which are respectively set on two large reels 142.

[0064] The advantages of the self-resetting anchoring device 1 that can adapt to changes in water level according to the present invention are that the self-resetting anchoring device 1 can be used in working environments with large changes in water level; the components of the self-resetting anchoring device 1 can be prefabricated and connected by fastening nuts, etc., making installation convenient, quick and easy, and at a low cost.

[0065] The following is based on Figures 1-5 The self-resetting anchoring device 1 that can adapt to changes in water level according to the present invention will be described in detail.

[0066] Please refer to Figure 1-5 The present invention provides a method for using a self-resetting anchoring device 1 that can adapt to changes in water level, comprising:

[0067] In the initial state, the area in use is at the lowest water level, the combined disc spring 1321 assembly is in a pre-compressed state, the bottom of the upper reset sleeve 131 and the lower steel plate 133 are tightly fitted, and the first anchoring cable 11 and the second anchoring cable 12 are both in a taut state.

[0068] When the water level in the area rises, the anchor rope synchronization mechanism 14 releases the second anchor cable 12 and simultaneously contracts the first anchor cable 11. The upper reset sleeve 131 moves along the contraction direction of the first anchor cable 11, and the upper reset sleeve 131 disengages from the lower steel plate 133. The combined disc spring 1321 assembly further contracts, so that both the first anchor cable 11 and the second anchor cable 12 are in a taut state.

[0069] When the water level in the area drops, the disc spring bolt assembly 132 releases the stored elastic potential energy, causing the upper reset sleeve 131 to move along the elongation direction of the first anchoring cable 11. This causes the upper reset sleeve 131 to move closer to the lower steel plate 133, driving the anchor rope synchronization mechanism 14 to release the first anchoring cable 11 and simultaneously contract the second anchoring cable 12, so that both the first anchoring cable 11 and the second anchoring cable 12 are in a taut state.

[0070] In practice, when the water level in the area rises, the net distance between the floating array float 2 and the anchor rope synchronization device increases, the bearing 141 rotates in the forward direction, releasing the third anchor rope 121 and contracting the second anchor rope 112. The contraction of the second anchor rope 112 drives the upper reset sleeve 131 to move in the direction of the contraction of the second anchor rope 112, thereby further compressing the combined disc spring 1321. In this way, the second anchor rope 112 and the third anchor rope 121 are always in a taut state.

[0071] When the water level in the area drops, the net distance between the floating array float 2 and the anchor rope synchronization device decreases, and the third anchor rope 121 is about to enter a slack state. Since the disc spring bolt assembly 132 contains elastic potential energy, the combined disc spring 1321 releases elastic potential energy to cause the upper reset sleeve 131 to move along the extension direction of the second anchor rope 112. That is, the distance between the upper reset sleeve 131 and the lower steel plate 133 decreases, the second anchor rope 112 is released, and the bearing 141 rotates in the opposite direction, which in turn causes the third anchor rope 121 to contract. In this way, the second anchor rope 112 and the third anchor rope 121 are always in a taut state.
