Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaics, specifically to an anchoring system for marine photovoltaic floating bodies. Background Technology

[0002] With the development of photovoltaic technology, photovoltaics have been applied on a large scale and systematically in various fields. As the environmental problems brought about by the oil and petrochemical industry become increasingly prominent, the issue of clean and green energy is receiving more and more attention.

[0003] With the global development of the photovoltaic industry, photovoltaics have received increasing attention due to their advantages such as low cost and no pollution. The biggest challenge for photovoltaic power generation is that it requires a large amount of land. The ever-increasing land costs may restrict the further development of the photovoltaic industry. On this basis, using the vast sea area to deploy photovoltaic equipment for photovoltaic power generation will be a new opportunity for the further development of the photovoltaic industry. Compared with the water surface photovoltaics that are already used in various reservoirs, lakes, fish ponds and other places, the large-scale application of photovoltaic power generation on the sea surface must solve the problem of fixed installation of photovoltaic arrays and ensure that photovoltaic products can withstand the strong winds and waves at sea without being damaged.

[0004] For marine photovoltaic (PV) arrays, anchor lines or chains should be connected to the hydrofoils surrounding the array and secured by anchors sunk to the seabed. However, in practice, the seabed is uneven and subject to sediment movement, leading to uneven stress on the anchor lines. Consequently, after a period of operation, some anchor lines fail to function as intended, resulting in an uneven force provided by the anchoring system. Furthermore, the forces acting on the PV array itself under strong winds and waves are unstable and uneven. Combined with the unevenness of the anchoring system, this results in a typical service life of less than three months for traditional PV arrays. In addition, the excessive number of counterweights, anchors, and other components in traditional PV array anchoring systems leads to extremely high costs and significantly increases the operational difficulty of array deployment. The numerous anchors and other components also cause interference between adjacent PV arrays, further impacting the overall service life and deployment complexity.

[0005] Based on this, the inventors conducted in-depth research on marine photovoltaic floats and their anchoring systems, and used the physical principles of netting to adjust the structural composition of the anchoring system while ensuring anchoring strength, thus designing a simpler anchoring system for marine photovoltaic floats that can solve the above problems. Summary of the Invention

[0006] To overcome the above problems, the inventors have designed an anchoring system for a marine photovoltaic float. The marine photovoltaic float comprises a photovoltaic array consisting of multiple float plates, with multiple hydrofoils arranged around the array. The anchoring system includes a rope net woven from multiple thin ropes and multiple thick ropes. One end of the rope net is fixed to the triangular stabilization system of the hydrofoils, and the other end is connected to the thick ropes. The thick ropes are wrapped around the lower outer side of the photovoltaic array, and the rope net is taut. Utilizing the physical principle of netting, the rope net can be tightened by pulling the end of the thick ropes outward, thus achieving the tightening and fixation of the hydrofoils and the photovoltaic array. Anchor ropes, anchor chains, counterweights, and anchors are then fixedly installed at the ends of the thick ropes to achieve the anchoring of the marine photovoltaic float, thereby completing this invention.

[0007] Specifically, this utility model provides an anchoring system for a marine photovoltaic float, the marine photovoltaic float comprising a photovoltaic array 1 composed of multiple float plates, and multiple hydrofoils 2 arranged around the photovoltaic array 1.

[0008] The anchoring system includes a rope net 3 made of thin ropes, one end of which is fixed to the hydrofoil 2 and the other end is connected to a thick rope 4. Both the rope net 3 and the thick rope 4 are wrapped around the lower outer side of the photovoltaic array 1, and the thick rope 4 can tighten the rope net 3.

[0009] Anchor rope 8, anchor chain 5 and anchor 6 are connected to the thick rope 4. The thick rope 4 is fixed and tightened by the anchor chain 5 and anchor 6, and then the hydrofoil 2 is tightened by the rope net 3.

[0010] The thick rope 4 consists of four strands, evenly distributed around the photovoltaic array 1.

[0011] Preferably, the photovoltaic array 1 is rectangular in shape, and a thick cord 4 is provided on the outer side of each side of the photovoltaic array 1.

[0012] A triangular stabilization system 21 is provided at the bottom of the hydrofoil 2. The triangular stabilization system 21 includes three ropes connected to the hydrofoil 2, and the three ropes are fixed together below the hydrofoil 2. The fixed position is called the fixed point.

[0013] One end of the rope net 3 is fixed to the hydrofoil 2 by being tied to the fixed point;

[0014] Multiple rope loops are provided at the other end of the rope net 3. The thick rope 4 passes through all the rope loops in sequence, thereby tightening the rope net 3 through the thick rope 4.

[0015] The edges of two adjacent thick ropes 4 converge and are connected together to the anchor rope 8, which is also connected to the anchor chain 5.

[0016] Preferably, the anchoring system includes four anchor ropes 8 and four anchor chains 5.

[0017] One end of the anchor chain 5 is connected to the anchor 6, and the other end is connected to the anchor rope 8. A counterweight 7 is provided on the end connected to the anchor rope 8.

[0018] The beneficial effects of this utility model include:

[0019] (1) The anchoring system and anchoring method for marine photovoltaic floats provided by this utility model greatly reduces the number of anchors and counterweights used in the anchoring system, while still having sufficient anchoring force, reducing anchoring costs and shortening the deployment cycle.

[0020] (2) The anchoring system and anchoring method for marine photovoltaic floats provided by this utility model utilize the physical principle of netting to tighten the netting by pulling the thick rope, thereby tightening the marine photovoltaic float. On this basis, the thick rope is fixed to the predetermined position by anchor and counterweight to achieve anchoring of the marine photovoltaic float. The anchoring process is simple and convenient, and the anchoring devices involved are simple and easy to operate, which can greatly improve the efficiency of anchoring operations.

[0021] (3) The anchoring system and anchoring method for marine photovoltaic floats provided by this utility model can adapt to uneven seabed and silt flow, reduce the deployment restrictions of high marine photovoltaic floats, and further improve economic benefits and service life.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent.

[0035] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0036] This utility model provides an anchoring system for marine photovoltaic floating bodies, such as... Figure 1 Figure 2 As shown, the marine photovoltaic float includes a photovoltaic array 1 composed of multiple floats, and multiple hydrofoils 2 are arranged around the photovoltaic array 1. Preferably, a floating channel for discharging electric wires can also be set in the photovoltaic array. In the photovoltaic array, adjacent floats, floating channels and hydrofoils are connected by anchor chains to ensure that the connection strength between them is strong enough and will not break or separate under the action of strong winds and waves.

[0037] The anchoring system includes a rope net 3 made of thin ropes; one end of the rope net 3 is fixed to the hydrofoil 2, and the other end is connected to a thick rope 4. The hydrofoil 2 is provided with outwardly protruding fixing rings. There are three fixing rings, one at each end of the hydrofoil 2 and one at the bottom. A short rope is connected to each of the three fixing rings. The three short ropes are fixed to each other at the bottom. The fixing point is the fixing point. These three short ropes form a triangular stabilization system 21.

[0038] Preferably, multiple loops can be provided at the end of the rope net 3 that is connected to the thick rope 4. The thick rope 4 passes through all the loops, thereby connecting the rope net 3 and the thick rope 4. This connection method allows the rope net 3 to slide to a certain extent on the thick rope 4, so as to adjust its position and tighten the rope net 3 to the maximum extent.

[0039] Preferably, such as Figure 1 As shown, a triangular connecting line is also provided between two adjacent hydrofoils 2 to further fix the hydrofoils to the connecting anchor chain of the photovoltaic array 1.

[0040] In this application, the terms "thick rope" and "thin rope" are relative concepts. Thick ropes are designed to withstand greater tensile force, while thin ropes exert less force than thick ropes. Both thick and thin ropes can be made of steel wire rope.

[0041] In this application, the weft and warp threads of the rope net 3 can be fixed together by binding or weaving, etc. By fixing them together to form a net, the firmness and stability of the anchoring system can be further improved, its ability to resist wind and waves can be enhanced, it is not easily damaged, and its service life can be extended.

[0042] Both the rope net 3 and the thick rope 4 are wrapped around the lower outer side of the photovoltaic array 1, and the thick rope 4 can tighten the rope net 3. A certain distance is maintained between the thick rope 4 and the photovoltaic array 1 to ensure that the rope net 3 can be fully tightened and that each thin rope of the rope net 3 can transmit force, thereby keeping the tension on the photovoltaic array 1 in a balanced state and improving its service life.

[0043] Anchor rope 8, anchor chain 5 and anchor 6 are connected to the thick rope 4. The thick rope 4 is fixed and tightened by the anchor chain 5 and anchor 6, and then the hydrofoil 2 is tightened by the rope net 3.

[0044] In a preferred embodiment, multiple thick ropes 4 are provided and evenly distributed around the photovoltaic array 1; they can be set to 4, 6, 8, etc., as long as they are evenly distributed. Each thick rope 4 corresponds to a region of the photovoltaic array, and the rope net 3 in that region is fully tightened.

[0045] Preferably, the photovoltaic array 1 is rectangular in shape. Accordingly, setting four thick ropes 4 can be a preferred embodiment, so that a thick rope 4 is set on the outer side of each side of the photovoltaic array 1.

[0046] In a preferred embodiment, one end of the rope net 3 is fixed to the hydrofoil 2 by tying it to the fixed point; since there are multiple hydrofoils 2, each hydrofoil 2 has a corresponding fixed point, so there are multiple fixed points, and each fixed point is tied to the rope net 3.

[0047] Multiple rope loops are provided at the other end of the rope net 3. The thick rope 4 passes through all the rope loops in sequence, thereby tightening the rope net 3 through the thick rope 4. After the rope net 3 is laid out, it surrounds the lower outer side of the photovoltaic array 1 and is in the shape of a frustum that is narrower at the top and wider at the bottom.

[0048] When the rope net 3 is unfolded and placed in the water, the rope net 3 forms a predetermined angle with the vertical direction. This angle is affected by factors such as water depth and the size of the photovoltaic array, and is generally set to 30-60 degrees. This design can further improve the stability of the marine photovoltaic float and reduce the breakage rate of the rope.

[0049] In a preferred embodiment, the edges of two adjacent thick ropes 4 converge and are further connected to an anchor rope 8, which is also connected to an anchor chain 5; preferably, the anchoring system has a total of four anchor ropes 8 and four anchor chains 5. The four anchor chains 5 are distributed at the four corners of the photovoltaic array to ensure sufficient tension on the thick ropes 4.

[0050] In a preferred embodiment, one end of the anchor chain 5 is connected to the anchor 6, and the other end is connected to the anchor rope 8, with a counterweight 7 provided at the end connected to the anchor rope 8. This counterweight 7 allows both the anchor chain and the anchor to sink to the seabed, facilitating sufficient anchoring through the anchor structure.

[0051] This invention also provides a method for anchoring a marine photovoltaic float, which is achieved through the anchoring system for the marine photovoltaic float described above.

[0052] Preferably, the method includes the following steps:

[0053] Step 1: Connect multiple floating panels to form a photovoltaic array 1, and connect and arrange hydrofoils 2 at the edge of the photovoltaic array 1;

[0054] Step 2: Secure the rope net 3 in the anchoring system to the hydrofoil 2; wherein, one end of the rope net 3 is secured to the fixed point of the triangular stabilization system 21.

[0055] Then control the thick rope 4 to pass through the rope loop at the other end of the rope net 3;

[0056] Step 3: Connect and fix the thick rope 4 to the anchor rope 8, connect and fix the anchor rope 8 to the anchor chain 5, and then install the anchor 6 and the counterweight 7 on the anchor chain 5.

[0057] Step 4: Arrange the photovoltaic array 1 in the predetermined water area, and simultaneously place anchors 6 and counterweights 7 around the photovoltaic array 1. The tension of the counterweights 7 is used to tighten the thick rope 4 and the rope net 3, so that the rope net 3 of the anchoring system is fully extended and tightens the photovoltaic array 1.

[0058] The marine photovoltaic float with the above-mentioned anchoring system operated continuously for 4 months in sea state 2-3 without any capsizing accidents, and its deployment position remained unchanged. Inspection of the anchoring system's rope net and thick rope revealed no damage.

[0059] The present invention has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and serve only an illustrative purpose. Based on this, various substitutions and improvements can be made to the present invention, all of which fall within the protection scope of the present invention.
