Technical Field
[0001] This invention relates to the field of marine engineering technology, and in particular to a sliding launching structure for a floating marine photovoltaic module and its operating method. Background Technology
[0002] Developing and utilizing solar energy resources is a significant step in my country's transition to renewable energy, possessing enormous potential to meet global energy demands. Over the past decade, the photovoltaic industry has expanded at an average annual growth rate of 133%. Following global trends and vigorously promoting the rational utilization of solar energy resources aligns with the needs of the times and global strategies. With my country's vigorous promotion of its marine economy and continuous exploration of deep-sea resources, the development of floating offshore photovoltaic systems has been put on the agenda.
[0003] Compared to onshore photovoltaic systems, floating offshore photovoltaic systems are easier to track, eliminating the need for complex tracking systems on land. Solar energy can be tracked through floating modules, resulting in lower energy consumption, lower cost, and higher efficiency than onshore photovoltaic systems under the same conditions.
[0004] Despite its significant development advantages, offshore floating photovoltaic (PV) systems also face considerable challenges in installation and construction. Currently, the foundation types for floating PV systems under research or undergoing trial installations are primarily semi-submersible truss, thin-film, or concrete foundations, often in a multi-module matrix configuration. Due to structural limitations, hoisting can easily lead to breakage or damage to the floating PV modules; wet towing installation is constrained by wind and wave conditions, easily causing collisions or water accumulation on the modules.
[0005] Designing a structure that avoids the difficulties of hoisting floating offshore photovoltaic modules and prevents them from being affected by wind and waves during launching is a problem that needs to be solved by those skilled in the art. Summary of the Invention
[0006] In view of the shortcomings of the prior art described above, the technical problem solved by the present invention is to provide a sliding launching structure and its working method for floating marine photovoltaic modules that can avoid the difficulties caused by hoisting floating marine photovoltaic modules and avoid the impact of wind and waves on floating marine photovoltaic modules during the launching process.
[0007] To achieve the above and other related objectives, the present invention provides a sliding launching structure for a floating offshore photovoltaic module, comprising:
[0008] A sliding plate is provided, one end of which is movably mounted on the side of the main construction vessel's hull. The sliding plate is connected to a plate drive device, which can drive the sliding plate to swing relative to the main construction vessel. When the sliding plate is in operation, it moves to a position away from the main construction vessel's hull, and is inclined relative to the horizontal plane. A hull sliding groove is provided on the main construction vessel's deck. A plate sliding groove is provided on the sliding plate. When the sliding plate is in operation, the output end of the hull sliding groove is opposite to the input end of the plate sliding groove, and the hull sliding groove and the plate sliding groove form a guide groove.
[0009] A slider is disposed in the guide groove, and the slider can move in the guide groove; a floating marine photovoltaic module is disposed above the slider, and the lower part of the floating marine photovoltaic module is provided with a mooring hole;
[0010] The drum is installed on the main construction vessel;
[0011] A cable, one end of which is wound around the drum, and the other end of which passes through the mooring hole and is connected to the tugboat. The cable and the mooring hole are detachably connected.
[0012] Preferably, the upper part of the drum is provided with a through hole, and the cable is led out from the through hole.
[0013] Preferably, the drum is connected to a transmission device, which drives the drum to rotate.
[0014] Preferably, the hull groove is embedded in the top surface of the ship deck of the main construction vessel; the plate groove is embedded in the top surface of the sliding plate.
[0015] Preferably, the plate driving device is a hydraulic device, and the top support component of the hydraulic device is connected to the sliding plate.
[0016] Preferably, the cable and the mooring hole can be detachably connected via a connector.
[0017] The present invention discloses a method for the operation of the sliding launching structure of a floating offshore photovoltaic module:
[0018] The floating marine photovoltaic module is set above the slider. After the other end of the cable passes through the mooring hole, the other end of the cable is connected to the tugboat. The cable is connected to the mooring hole.
[0019] During operation, the tugboat tows the cable, which drives the slider to move in the guide groove. The floating marine photovoltaic module above the slider also moves with the slider. The floating marine photovoltaic module slides from the ship's deck to the sliding plate and then enters the water. After the floating marine photovoltaic module is towed into place, the cable is disconnected from the mooring hole, the cable is released, and the mooring system is connected to the mooring hole. The tugboat then releases the cable, and the drum retracts the cable, completing the installation of the floating marine photovoltaic module.
[0020] As described above, the sliding launching structure and its operating method for the floating offshore photovoltaic module of the present invention have the following beneficial effects:
[0021] 1) The sliding launching structure and its working method of the floating marine photovoltaic module of the present invention can effectively reduce the difficulty of transporting and installing the floating marine photovoltaic module and avoid the floating marine photovoltaic module being affected by wind and waves during the launching process, that is, to avoid the floating marine photovoltaic module being hit by waves.
[0022] 2) The sliding launching structure of floating offshore photovoltaic modules can effectively assist in the loading and launching of floating offshore photovoltaic modules. The construction method of floating offshore photovoltaic modules does not require the use of cranes, eliminating the difficulty of hoisting, which can avoid damage to floating offshore photovoltaic modules and ensure the structural safety of floating offshore photovoltaic modules.
[0023] 3) The drum of the sliding launching structure of the floating marine photovoltaic module of the present invention can control the rate of cable winding and unwinding in real time according to the changes in tidal current and wind speed, so as to realize the uniform launching of the floating marine photovoltaic module, maintain sliding stability, and improve construction safety.

[0047] like Figures 1 to 4 As shown, the sliding launching structure of the floating offshore photovoltaic module in this embodiment includes:
[0048] A sliding plate 100 is movably mounted at one end on the side of the hull 11 of the main construction vessel 10. The sliding plate 100 is connected to a plate drive device 200, which can drive the sliding plate 100 to swing relative to the main construction vessel 10. When the sliding plate 100 is in operation, it moves to a position away from the hull 11 of the main construction vessel 10, and the sliding plate 100 is inclined relative to the horizontal plane. A hull slide groove 13 is provided on the ship deck 12 of the main construction vessel 10. A plate slide groove 14 is provided on the sliding plate 100. When the sliding plate 100 is in operation, the output end of the hull slide groove 13 is opposite to the input end of the plate slide groove 14, and the hull slide groove 13 and the plate slide groove 14 form a guide slide groove 15.
[0049] A slider 300 is disposed in a guide groove 15 and can move within the guide groove 15; a floating offshore photovoltaic module 20 is disposed above the slider 300 and a mooring hole 21 is provided at the lower part of the floating offshore photovoltaic module 20.
[0050] 400 drums are installed on the main construction vessel 10.
[0051] The cable 500 has one end wound around the drum 400 and the other end passing through the mooring hole 21. The other end of the cable 500 is connected to the tugboat 30. The cable 500 and the mooring hole 21 are detachably connected.
[0052] The sliding launching structure of the floating offshore photovoltaic module and the construction method of the floating offshore photovoltaic module 20 of the present invention can effectively reduce the transportation and installation difficulty of the floating offshore photovoltaic module 20 and avoid the floating offshore photovoltaic module 20 from being hit by waves.
[0053] The sliding launching structure of the floating offshore photovoltaic module can effectively assist the loading and launching operations of the floating offshore photovoltaic module 20. The construction method of the floating offshore photovoltaic module 20 does not require the use of a crane, eliminating the difficulty of hoisting, which can avoid damage to the floating offshore photovoltaic module 20 and ensure the structural safety of the floating offshore photovoltaic module 20.
[0054] The drum 400 of the sliding launching structure of the floating marine photovoltaic module of the present invention can control the speed of winding and unwinding the cable 500 in real time according to the changes in tidal current and wind speed, so as to achieve uniform launching of the floating marine photovoltaic module 20, maintain sliding stability, and improve construction safety.
[0055] The drum 400 is located below the deck 12 of the main construction vessel 10. A through hole is provided in the upper part of the drum 400, through which the cable 500 is led out. This structure facilitates the cable 500 being led out from the drum 400.
[0056] The drum 400 is connected to the transmission device 700, which drives the drum 400 to rotate. The transmission device 700 provides power to the drum 400 and drives the drum 400 to rotate, thereby releasing the cable 500.
[0057] The hull slide 13 is embedded in the top surface of the ship deck 12 of the main construction vessel 10; the plate slide 14 is embedded in the top surface of the sliding plate 100, so the overall structure of the sliding launching structure is more compact.
[0058] The plate drive device 200 is a hydraulic device 600, and the top support component of the hydraulic device 600 is connected to the sliding plate 100.
[0059] The sliding plate 100 can adjust the deployment angle of the floating offshore photovoltaic module 20 according to the weight, size and internal connection method of different types of floating offshore photovoltaic modules 20 through the top support component of the hydraulic device 600, so as to meet the stability requirements of the floating offshore photovoltaic module 20 when it is launched.
[0060] When the sliding plate 100 is in operation, it is lifted by the support component of the hydraulic device 600. One end of the sliding plate 100 connected to the main construction vessel 10 is level with the surface of the ship deck 12, and the other end of the sliding plate 100 is tilted into the water. When the sliding plate 100 is not in operation, it moves to a position close to the side 11 of the main construction vessel 10 and is retracted to the side of the side 11 of the main construction vessel 10. Figure 1 In the diagram, a solid line for the sliding plate 100 indicates the position of the sliding plate 100 when it is in operation; a dashed line for the sliding plate 100 indicates the position of the sliding plate 100 when it is not in operation.
[0061] The cable 500 and the mooring hole 21 can be detachably connected via a connector. In this embodiment, the connector can be a shackle or the like.
[0062] The cable 500 of the sliding launching structure connects to the existing mooring hole 21 of the floating offshore photovoltaic module 20 during the sliding process. The tension of the cable 500 can be used as the main driving force for towing the floating offshore photovoltaic module 20 into the water, while preventing the cable 500 from detaching from the floating offshore photovoltaic module 20.
[0063] During transportation and installation, the mooring holes 21 and cables 500 on the floating offshore photovoltaic module 20 are fixed by connectors.
[0064] The present invention also relates to a construction method for a floating offshore photovoltaic module 20, wherein the floating offshore photovoltaic module 20 is installed on a sliding launching structure;
[0065] The floating offshore photovoltaic module 20 is positioned above the slider 300. The other end of the cable 500 passes through the mooring hole 21 and is connected to the tugboat 30. The cable 500 is connected to the mooring hole 21. The floating offshore photovoltaic module 20 is positioned above the cable 500.
[0066] During operation, the tugboat 30 tows the cable 500, which in turn drives the slider 300 to move in the guide chute 15. The floating marine photovoltaic module 20 above the slider 300 also moves with the slider 300. The floating marine photovoltaic module 20 slides from the ship's deck 12 to the sliding plate 100 and then enters the water. After the floating marine photovoltaic module 20 is towed into place, the cable 500 is disconnected from the mooring hole 21, the cable 500 is released, and the mooring system 40 is connected to the mooring hole 21. The tugboat 30 then releases the cable 500, and the drum 400 retracts the cable 500. The installation of the floating marine photovoltaic module 20 is then completed.
[0067] The sliding launching structure and construction method of the floating offshore photovoltaic module can effectively reduce the construction difficulty of the floating offshore photovoltaic module 20 and increase the types of floating offshore photovoltaic modules 20 that can be installed, thereby improving construction efficiency and safety and saving construction costs.
[0068] With the development of deep-sea areas and the efficient utilization of marine areas, the demand and benefits of floating offshore photovoltaic modules 20 are increasing. Floating offshore photovoltaic modules 20 have a large area and a low height above the sea surface. The construction method of floating offshore photovoltaic modules 20 can avoid the problems of difficult transportation and installation and easy wave impact. The construction method of floating offshore photovoltaic modules 20 will not limit the large-scale application of floating offshore photovoltaic modules 20.
[0069] The construction vessel can complete the integrated transportation and installation of floating offshore photovoltaic modules 20. The transportation and installation includes various foundation types of floating offshore photovoltaic modules 20, such as thin-film type and semi-submersible truss type. The sliding launching structure of floating offshore photovoltaic modules has a wide range of applications, is less restricted, and saves construction and installation costs, resulting in significant cost reduction and efficiency improvement.
[0070] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
