Description

TECHNICAL FIELD

[0001] The present application relates to the field of offshore photovoltaic power generation, in particular to a jacket foundation shared anchoring system and method for offshore wind-solar co-located power generation. BACKGROUND

[0002] With the development of marine engineering technology, the pace of developing new energy gradually moves from land to sea, and offshore photovoltaic power generation technology and offshore wind power technology have developed rapidly.

[0003] Currently, the wind turbine used in offshore wind power technology is usually supported by a jacket foundation. The pile body is driven into the deep seabed, and the friction between the pile and the seabed soil and the bearing capacity of the pile end are used to fix the jacket foundation. These piles can withstand huge vertical and horizontal loads to ensure their stability under the action of wind, wave and current. The research on floating offshore photovoltaic platforms is still in its infancy, and the anchoring methods used at present are different, mainly including catenary mooring and tension mooring.

[0004] In order to fully improve the power generation efficiency and save space and facility deployment cost, the wind-solar co-located power generation technology of constructing offshore photovoltaic power generation and offshore wind power projects in the same area has become a new trend. However, the existing independent anchoring system has some problems in this scenario.

[0005] On the one hand, the operating environment and stress characteristics of offshore photovoltaic platforms and offshore wind turbine jacket foundations are different. The wind turbine jacket foundation mainly bears the weight of the wind turbine generator, wind load and wave load, while the photovoltaic platform is relatively light, but the orientation and angle of the solar panels need to be considered. This makes their requirements for the anchoring system different, and the traditional anchoring method cannot meet the needs of both. On the other hand, when wind and waves act on the offshore wind-solar co-located system, the wind turbine jacket foundation and the photovoltaic platform will move to different degrees, such as sway, surge, heave, etc. These movements may cause the respective mooring cables to interfere with each other, affecting the stability and safety of the system.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0022] As shown in Figure 1 and 2 A jacket foundation shared mooring system for offshore wind and light co-sited power generation includes a plurality of jacket foundations 1 for supporting wind turbines, and the plurality of jacket foundations 1 are arranged in an array.

[0023] All the jacket foundations 1 are divided into groups, and the number of jacket foundations 1 in each group is at least three. Jacket foundations 1 in the same group can enclose a photovoltaic installation area for accommodating a floating photovoltaic platform 3.

[0024] The jacket foundation 1 includes a suction pile 4 inserted into the seabed, the suction pile 4 supports the wind turbine through a support frame 7, and the suction pile 4 is fixedly and detachably connected with a plurality of mooring lines 2 for connecting the floating photovoltaic platform 3, and the mooring lines 2 extend into the photovoltaic installation area.

[0025] The present application is applicable to offshore wind and light co-sited power generation projects, i.e. power generation projects that include both wind turbines and floating photovoltaic platforms 3. During construction, first, the positions of the jacket foundations 1 are selected according to the design requirements of the project, and the jacket foundations 1 are installed. The distribution mode and area of the photovoltaic installation area enclosed by the jacket foundations 1 are determined according to the design requirements of the project. Then, the wind turbines are arranged on the jacket foundations 1, and the floating photovoltaic platform 3 is arranged in the photovoltaic installation area. Subsequently, the floating photovoltaic platform 3 is connected with the jacket foundation 1 by using the mooring lines 2, and the main construction of the project is completed.

[0026] The present application uses the jacket foundation 1 to support the wind turbine, and uses the jacket foundation 1 to enclose the photovoltaic installation area for installing the floating photovoltaic platform 3, and then uses the mooring lines 2 to anchor the floating photovoltaic platform 3, so that the floating photovoltaic platform 3 and the wind turbine can share the jacket foundation 1, and the shared mooring is realized, which can effectively realize wind and light co-sited power generation in the same area. On the other hand, the floating photovoltaic platform 3 can effectively absorb part of the wave energy, avoid the jacket foundation 1 from being damaged by the sea waves for a long time, and ensure the stability of the jacket foundation 1 and the stability of the wind turbine; the wind turbine can also absorb the energy of the sea wind, which can reduce the vibration amplitude of the floating photovoltaic platform 3 caused by the sea wind, ensure the stability of the floating photovoltaic platform 3, and thus improve the power generation efficiency of the floating photovoltaic platform 3.

[0027] The jacket foundation 1 of the present application can support both wind turbines and pull floating photovoltaic platforms 3, thereby integrating wind power and photovoltaic power generation in the same sea area, more efficiently utilizing offshore space resources, and improving energy output per unit area. The present application allows photovoltaic panels to be arranged in the gaps of the wind farm or below the wind turbine units, thereby increasing energy output without occupying additional large areas of the sea, and can share infrastructure such as power transmission systems, monitoring systems, and maintenance facilities, thereby reducing the cost of separately constructing wind or photovoltaic power generation. Wind energy and solar energy peak at different times of the day, allowing the entire power plant to output more stable and reliable electricity, reducing electricity fluctuations, and reducing the impact on the power grid. During construction, because the maintenance team can simultaneously service both wind power and photovoltaic power facilities, the time and risk of offshore operations can also be reduced.

[0028] The following provides two embodiments of the jacket foundation 1. Embodiment one

[0029] As shown in Figures 3 to 6 , the specific structure of the jacket foundation 1 is that the jacket foundation 1 includes an anchor ring 5 fixedly arranged at the top of the suction cylinder 4, and a plurality of connection assemblies 6 for connecting the mooring cables 2 are fixedly arranged on the anchor ring 5. The connection assembly 6 includes a fixed ring 18 and a first connection ring 19, wherein the fixed ring 18 is fixedly arranged on the anchor ring 5, and the first connection ring 19 passes through the fixed ring 18 and is detachably connected with the mooring cable 2. During installation of the jacket foundation 1, the suction cylinder 4 is continuously conveyed downward, and after the suction cylinder 4 is inserted into the seabed, the seawater and the floating soil in the suction cylinder 4 are pumped out. After the position of the suction cylinder 4 is stabilized, the mooring cable 2 is connected with the anchor ring 5, without the need for complex operations under the sea surface, making it easier to construct.

[0030] The specific structure of the anchor ring 5 is that the anchor ring 5 includes two half rings 9, the first ends of the two half rings 9 are connected by a hinge 8, and the second ends of the two half rings 9 are detachably connected. The two half rings 9 and the hinge 8 can be prefabricated as a whole, and during installation of the anchor ring 5, the second ends of the two half rings 9 are connected, and the two second half rings 9 are connected with the suction cylinder 4, thereby completing the installation. The installation process is simple and efficient.

[0031] The detachable connection mode of the second ends of the two half-rings 9 is that the half-rings 9 include inner sides 14 and outer sides 12, the inner sides 14 and the outer sides 12 are both arc-shaped plates and are coaxially arranged, the inner sides 14 and the outer sides 12 are connected through a connecting part 13, and a fixing ring 18 is fixedly arranged on the connecting part 13. One inner side 14 and one outer side 12 of one half-ring 9 are each provided with a positioning groove 15, and one inner side 14 and one outer side 12 of the other half-ring 9 are each fixedly connected with a positioning rod 16. The positioning rod 16 is inserted into the positioning groove 15 and is connected through a pin 17. When the second ends of the two half-rings 9 are connected, the two half-rings 9 are rotated around the axis of the hinge 8 by rotating the two half-rings 9 until the positioning rod 16 is inserted into the positioning groove 15. At this time, the two half-rings 9 are combined into a complete anchoring ring 5, and then the positioning rod 16 and the side wall of the positioning groove 15 are connected through the pin 17, so that the second ends of the two half-rings 9 are connected, and the operation process is simple. The position where the pin 17 contacts the two half-rings 9 can be welded and reinforced, so as to further improve the structural strength of the anchoring ring 5. On the other hand, between the inner side 14 and the outer side 12 of the half-ring 9, a containing gap is left. When the half-ring 9 is connected with the suction cylinder 4, the top of the suction cylinder 4 can be inserted into the containing gap. At this time, the inner side 14 is located on the inner side of the suction cylinder 4, the outer side 12 is located on the outer side of the suction cylinder 4, and the connecting part 13 is attached to the top end of the suction cylinder 4. Thus, the inner side 14 and the outer side 12 are limited by the suction cylinder 4, which can prevent the anchoring ring 5 from deviating or shaking in the horizontal direction, improve the stability of the position of the anchoring ring 5, and further ensure the stability of the floating photovoltaic platform 3.

[0032] After the top of the suction cylinder 4 enters the containing space, the anchoring ring 5 needs to be further connected with the suction cylinder 4. In order to further simplify the construction process and reduce the construction difficulty, the half-ring 9 is fixedly connected with the suction cylinder 4 through a plurality of mounting rods 10. A plurality of mounting insertion holes 11 for matching the mounting rods 10 are arranged on the suction cylinder 4, and a plurality of through holes for the mounting rods 10 to pass through are arranged on the inner side 14 and the outer side 12. Through the cooperation of the mounting rod 10 and the mounting insertion hole 11, the suction cylinder 4 and the anchoring ring 5 can be connected and reinforced only by using the plug-in mode, which is simple to operate and fast to install. Moreover, the connection is achieved through a plurality of mounting rods 10, and the directions of different mounting rods 10 are different, which can effectively ensure the connection strength of the suction cylinder 4 and the anchoring ring 5. Embodiment two

[0033] As shown in Figures 7 to 11 , a plurality of wing plates 20 are fixedly arranged on the circumferential side wall of the suction cylinder 4 and are uniformly distributed in the circumferential direction. The wing plates 20 are parallel to the axis of the suction cylinder 4 and are inserted into the seabed. The top of the suction cylinder 4 is closed by a top plate, a plurality of second connecting rings 22 are fixedly arranged on the top plate, and the second connecting rings 22 are detachably connected with the mooring cable 2.

[0034] The wing plate 20 includes a plate body 24, with recessed portions 26 disposed in the middle of both sides of the plate body 24. A diverter portion 25 is disposed on one edge of the plate body 24 facing away from the suction cylinder 4. The diverter portion 25 has a semicircular cross-section, with its arc-shaped edge facing away from the suction cylinder 4. The provision of the wing plate 20 enhances the suction cylinder 4's anti-overturning capability and horizontal load-bearing capacity, thereby more stably supporting the wind turbine and the towed floating photovoltaic platform 3, ensuring the safety and reliability of the entire power plant. The second connecting ring 22 is detachably connected to the mooring line 2; installation is simplified by simply hooking the mooring line 2 to the second connecting ring 22.

[0035] In order to further facilitate the insertion of the wing plate 20 into the seabed, a piercing portion 27 is connected to the bottom of the diversion portion 25. The piercing portion 27 is conical, and the tip is arranged downward.

[0036] The second connecting ring 22 is specifically configured as follows: the second connecting ring 22 is fixedly connected to the base 21, which is in turn fixedly connected to the top plate. Multiple fixed wedges 23 are fixedly mounted on the sidewalls of the base 21, with the larger ends of the fixed wedges 23 fixedly connected to the top plate. The combination of the base 21 and the fixed wedges 23 enhances the stability of the second connecting ring 22, thereby ensuring the stability of the ends of the mooring lines 2 and, therefore, the ability to stably pull the floating photovoltaic platform 2.

[0037] like Figure 12 As shown, based on the above two embodiments, in order to further ensure the position stability of the floating photovoltaic platform 3 and prevent damage to some mooring cables 2 or high-frequency vibration that may cause significant displacement of the floating photovoltaic platform 3, among all mooring cables 2 connected to the same jacket foundation 1, the mooring cables 2 located at the edge are reinforced using multiple position reinforcement assemblies. The position reinforcement assembly includes two fixedly connected rings 28, which are mounted on one mooring cable 2. After the jacket foundation 1 is connected to the floating photovoltaic platform 3 using the mooring cables 2, the position reinforcement assemblies are used to reinforce the adjacent two mooring cables 2 at the edge. Specifically, the two rings 28 of the position reinforcement assembly are respectively mounted on the adjacent two mooring cables 2. The two fixedly connected rings 28 maintain a stable distance between the two adjacent mooring cables 2, thereby ensuring a stable connection between the jacket foundation 1 and the floating photovoltaic platform 3.

[0038] The specific connection mode between the two collars 28 in the position reinforcing assembly is that the collar 28 is fixedly connected with a connecting rod 29 extending along the radial direction of the collar 28, the connecting rod 29 is fixedly connected with an adapter plate 30, and the connecting rod 29 and the adapter plate 30 are perpendicular to each other, and the two adapter plates 30 are fixedly connected through the combination of a plurality of adapter bolts 31 and adapter nuts 32. The two connecting rods 29 can have a certain distance between the two collars 28, and according to the specific situation of the mooring rope 2 to be connected, a connecting rod 29 with a suitable length can be selected to ensure that the two adjacent mooring ropes 2 can be smoothly connected through the position reinforcing assembly.

[0039] The method for sharing anchorages of jacket foundations for offshore wind and solar co-located power generation is based on the above-mentioned system for sharing anchorages of jacket foundations for offshore wind and solar co-located power generation, and comprises the following steps S1-S3.

[0040] S1, deploy the jacket foundations 1 based on the installation requirements of wind turbines, and all the jacket foundations 1 are arranged in an array.

[0042] S3, place the floating photovoltaic platform 3 into the photovoltaic installation area, and connect the floating photovoltaic platform 3 with the jacket foundation 1 by using the mooring ropes 2, and one jacket foundation is connected with a plurality of mooring ropes 2. After the jacket foundation 1 and the floating photovoltaic platform 3 are connected by using the mooring ropes 2, the position reinforcing assembly is used to reinforce the adjacent two mooring ropes 2 among all the mooring ropes 2 located at the edge positions.
