Description

Technical Field

[0001] This invention relates to the field of optical energy storage straight-line flexible technology, and more specifically, to an optical energy storage straight-line flexible cable with corrosion resistance and its protective structure. Background Technology

[0002] The photovoltaic-storage-DC-flexible system is a new type of integrated energy utilization system that combines photovoltaic power generation, energy storage, DC power distribution, and flexible control technologies, aiming to achieve efficient energy utilization, flexible dispatch, and low carbon emissions. The photovoltaic power station is the core component of the system, generating electricity through a large-scale deployment of photovoltaic panels.

[0003] Because photovoltaic panels require a large footprint, and the land area suitable for building photovoltaic power plants is limited, marine photovoltaic power generation projects have gradually emerged. For example, deep-sea floating photovoltaic power generation projects use ring-shaped pipes assembled from prefabricated high-density polyethylene (HDPE) pipes as floating units. By setting four mooring points and multiple cables to anchor the floating units to the seabed, the stability of the floating body is significantly improved. A high-strength elastic film (0.3-0.5 mm thick) is laid in the middle of the floating body, allowing it to directly contact the seawater and move vertically with the waves (amplitude ±0.5 meters). Customized photovoltaic modules are then connected to the film via prefabricated connectors. Cables attached to the photovoltaic modules are tied around the floating body and ultimately transmitted to an energy storage station via submarine cables. By utilizing the cooling effect of water, the operating temperature of the photovoltaic modules can be reduced by 5-10°C, and the power generation efficiency can be increased by more than 10%.

[0004] To effectively utilize the cooling effect of seawater, the thin film needs to maintain the largest possible contact area with the seawater. Therefore, the thin film will fluctuate synchronously with the waves, and the photovoltaic modules installed on the thin film will also fluctuate synchronously. At this time, the cables on the photovoltaic modules and the connecting sections tied to the float will continuously swing, bend, and stretch due to the large fluctuation difference between the float and the thin film. Long-term, high-frequency, and large-amplitude deformation will seriously reduce the service life of the cables, thereby significantly reducing the overall service life of the equipment. Summary of the Invention

[0005] The present invention provides a corrosion-resistant photovoltaic energy storage straight flexible cable and its protective structure. The problem to be solved is that the cable on the existing photovoltaic module and the connection section tied to the float will continuously swing, bend and stretch due to the large fluctuation difference between the float and the film. Long-term high-frequency large-amplitude deformation will seriously reduce the service life of the cable, thereby significantly reducing the overall service life of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective structure for a photovoltaic energy storage straight flexible cable with corrosion resistance, comprising: a photovoltaic power generation mechanism, the photovoltaic power generation mechanism comprising an annular floating body tube floating on the water surface, the inner ring of the annular floating body tube being provided with a high-elastic film, and a plurality of photovoltaic panels being uniformly laid on the high-elastic film;

[0007] An installation ring is concentrically arranged on the annular floating tube, and the installation ring is arranged parallel to the annular floating tube. A protective mechanism is provided on the installation ring. The protective mechanism includes several protective sleeves fixedly installed on the installation ring, and both ends of the protective sleeves are open. A cable 1 is provided at both ends of the protective sleeves. The ends of the two cable 1s that are close to each other are connected to a cable 2. The cable 2 is located inside the cable 1. The end of the two cable 1s that is close to the high elastic film is connected to the corresponding photovoltaic panel, and the end of the two cable 1s that is close to the installation ring is fixedly connected to the installation ring.

[0008] In a preferred embodiment, two protective bags are symmetrically arranged inside the protective sleeve. The ends of the two protective bags near the high-elastic film are connected to the same annular connecting bag, and a water pipe is provided at the end of each protective bag near the mounting ring. A circulating water supply device is connected to the outside of the water pipe.

[0009] In a preferred embodiment, the second cable is located in the middle of the two protective bags, and the end of the second cable near the high-elastic film passes through the annular connecting bag, and the second cable is adapted to the protective bag.

[0010] In a preferred embodiment, a plurality of support components are uniformly fitted on the annular float tube. The support components are fixedly connected to the mounting ring and are used to fix the mounting ring above the annular float tube.

[0011] In a preferred embodiment, a plurality of cable fixing seats are uniformly arranged on the high-elastic film, and a section of cable connected to the photovoltaic panel is fixedly connected to the corresponding cable fixing seat.

[0012] In a preferred embodiment, a plurality of fixing rings are fitted onto the annular float tube, and a connecting rod is provided on the fixing ring, the connecting rod being fixedly connected to a corresponding protective sleeve.

[0013] In a preferred embodiment, a plurality of cable clamps are fitted onto the mounting ring, and the cable clamps are fixedly connected to a section of cable near the mounting ring.

[0014] In a preferred embodiment, a plurality of buoys are evenly arranged on the outer side of the annular floating tube.

[0015] In a preferred embodiment, the protective sleeve is inclined downward at the end near the elastic film.

[0016] A corrosion-resistant optical storage straight flexible cable includes a conductor, an insulation layer, a sheath, and a corrosion-resistant layer arranged sequentially from the inside to the outside of the conductor, and the cable passes through the interior of a protective sleeve.

[0017] The beneficial effects of this invention are as follows:

[0018] By setting up a protective structure, this invention can restrict the cable between the photovoltaic panel and the mounting ring to a small amplitude of oscillation within the protective sleeve when the high-elastic film fluctuates with the waves, thereby effectively reducing the deformation amplitude of the cable and significantly improving the service life of the cable.

[0019] This invention uses a recyclable water-filled protective bag to absorb cable vibration and reduce its vibration frequency, while also absorbing and carrying away some of the excess heat generated during cable transmission, thereby further improving the overall service life of the equipment.

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Refer to the instruction manual appendix Figures 1 to 4 A protective structure for a corrosion-resistant photovoltaic energy storage cable includes: a photovoltaic power generation mechanism 1, which includes an annular floating tube 11 floating on the water surface, a high-elastic film 12 arranged in the inner circle of the annular floating tube 11, and a plurality of photovoltaic panels 15 uniformly laid on the high-elastic film 12.

[0028] It should be noted that the photovoltaic power generation mechanism 1 is assembled from prefabricated pipe fittings made of high-density polyethylene (HDPE) or other materials with similar functions known to those skilled in the art, and the photovoltaic power generation mechanism 1 is hollow, thereby providing a certain support for the overall equipment.

[0029] Furthermore, the high-elastic film 12 is a high-strength elastic film, and the high-elastic film 12 is made of high-density polyethylene (HDPE) or other materials with similar functions known to those skilled in the art. The surface of the high-elastic film 12 can be coated with a nano anti-fouling coating to inhibit the adhesion of algae and shellfish, thereby significantly extending the cleaning cycle.

[0030] An installation ring 14 is concentrically arranged on the annular floating tube 11. The installation ring 14 is parallel to the annular floating tube 11. A protective mechanism 2 is provided on the installation ring 14. The protective mechanism 2 includes several protective sleeves 21 fixedly installed on the installation ring 14. Both ends of the protective sleeves 21 are open. A cable 24 is provided at both ends of the protective sleeves 21. The ends of the two cable 24 that are close to each other are connected to a cable 25. The cable 25 is located inside the cable 24. The end of the two cable 24 that is close to the high elastic film 12 is connected to the corresponding photovoltaic panel 15. The end of the two cable 24 that is close to the installation ring 14 is fixedly connected to the installation ring 14.

[0031] It should be noted that the mounting ring 14 is located above the annular float tube 11, and the mounting ring 14 is also a hollow annular tube made of the same material as the annular float tube 11; the second cable 25 is an elastic wire harness cable, and the second cable 25 is connected to the two sections of the first cable 24 as a whole cable. The stretchable range of the second cable 25 matches the fluctuation range of the high elastic film 12 and a certain amount of redundant space is reserved.

[0032] In this embodiment, the specific implementation scenario is as follows: the other end of a section of cable 24 connected to the photovoltaic panel 15 extends into the corresponding protective sleeve 21, and a section of cable 24 near the mounting ring 14 is fixed on the mounting ring 14. Due to the setting of cable 25, when the high-elastic film 12 and the photovoltaic panel 15 fluctuate up and down with the waves, cable 24 and cable 25 will only fluctuate slightly within the protective sleeve 21, thereby effectively reducing the deformation amplitude of cable 24 and cable 25, and thus significantly improving the service life of cable 24 and cable 25.

[0033] Refer to the instruction manual appendix Figure 3 and Figure 4 In this embodiment, two protective bags 22 are symmetrically arranged inside the protective sleeve 21. The ends of the two protective bags 22 near the high elastic film 12 are connected to the same annular connecting bag, and the ends of the two protective bags 22 near the mounting ring 14 are each provided with a water pipe 23, and the water pipe 23 is connected to a circulating water supply device.

[0034] It should be noted that the protective bag 22 has a semi-circular cross-section, and its inner diameter is larger than the overall diameter of cable 25. By connecting the upper and lower protective bags 22 to the same annular connecting bag, the two protective bags 22 are connected, similar to folding a water pipe once. The ends of the two protective bags 22 away from the annular connecting bag are connected to water pipes 23. The upper water pipe 23 is the input end, and the lower water pipe 23 is the output end. The circulating water supply device connected to the water pipes 23 can draw seawater into the protective bag 22 for circulation. Through the seawater circulating in the protective bag 22, a large part of the heat generated by cable 1 24 and cable 2 25 can be absorbed and carried away, thereby further improving the service life of the equipment.

[0035] Refer to the instruction manual appendix Figure 3 and Figure 4 In this embodiment, cable 25 is located in the middle of the two protective bags 22, and the end of cable 25 near the high elastic film 12 passes through the annular connecting bag, and cable 25 is compatible with the protective bag 22.

[0036] It should be noted that the ring-shaped connecting bag is circular with a hole in the middle through which cables 24 and 25 can pass. The water-filled protective bag 22 can absorb part of the vibration of cables 24 and 25 when they vibrate, thereby effectively reducing the deformation frequency of cables 24 and 25.

[0037] Refer to the instruction manual appendix Figure 1 and Figure 2 In this embodiment, a plurality of support components 13 are uniformly sleeved on the annular float tube 11. The support components 13 are fixedly connected to the mounting ring 14. The support components 13 are used to fix the mounting ring 14 above the annular float tube 11.

[0038] It should be noted that the support component 13, the annular float tube 11, and the mounting ring 14 are all detachable connections and can be connected by bolts or other quick-connect fittings. These are mature technologies well known to those skilled in the art and will not be described in detail in this embodiment.

[0039] Refer to the instruction manual appendix Figure 1 and Figure 2In this embodiment, a plurality of cable fixing seats 16 are uniformly arranged on the high elastic film 12, and a section of cable 24 connected to the photovoltaic panel 15 is fixedly connected to the corresponding cable fixing seat 16.

[0040] It should be noted that several photovoltaic panels 15 are connected in series, and each series contains dozens or more photovoltaic panels 15, which can be adjusted according to the actual situation. Each series is connected to the combiner box by a single set of cables 24, and one end of the single set of cables 24 can be fixed to the high-elastic film 12 through the cable fixing seat 16.

[0041] Refer to the instruction manual appendix Figure 1 and Figure 2 In this embodiment, a plurality of fixing rings 17 are sleeved on the annular float tube 11, and a connecting rod 18 is provided on the fixing ring 17. The connecting rod 18 is fixedly connected to the corresponding protective sleeve 21.

[0042] It should be noted that the size of the protective sleeve 21 can be adjusted according to the actual situation. The fixing ring 17 and the connecting rod 18 can work together to support the protective sleeve 21, thereby improving the stability of the protective sleeve 21.

[0043] Refer to the instruction manual appendix Figure 1 and Figure 2 In this embodiment, a plurality of cable fixing clips 19 are fitted on the mounting ring 14, and the cable fixing clips 19 are fixedly connected to a section of cable 24 near the mounting ring 14.

[0044] It should be noted that the cable clamp 19 can be adjusted in size according to actual conditions, and the cable clamp 19 and the mounting ring 14 are detachably connected by bolts or other quick-connect fittings. This is a well-known and mature technology in the art, and will not be described in detail in this embodiment.

[0045] Refer to the instruction manual appendix Figure 1 In this embodiment, several floats 3 are evenly arranged on the outer side of the annular float tube 11.

[0046] It should be noted that the installation of float 3 can effectively improve the overall stability of the equipment.

[0047] Refer to the instruction manual appendix Figure 1 and Figure 2 In this embodiment, the protective sleeve 21 is inclined downward at the end near the high elastic film 12.

[0048] It should be noted that the tilt angle of the protective sleeve 21 can be adjusted according to the actual situation to adapt to the fluctuation of the waves.

[0049] Refer to the instruction manual appendix Figure 5In this embodiment, the cable 24 includes a conductor 241. The outer side of the conductor 241 is provided with an insulation layer 242, a sheath 243 and a corrosion-resistant layer 244 from the inside out. The cable 24 passes through the inside of the protective sleeve 21.

[0050] It should be noted that, since this equipment is located at sea for extended periods, the corrosiveness of seawater is significantly stronger than that of terrestrial environments. Therefore, it is necessary to improve the corrosion resistance of cables 24 and 25. The corrosion-resistant layer 244 can be made of polyethylene (PE), polyvinyl chloride (PVC), neoprene rubber, or other materials with good corrosion resistance. This will improve the water resistance, chemical corrosion resistance, and weather resistance of cables 24 and 25, and provide good resistance to seawater, salts, acids, and alkalis. These materials also have high elasticity and abrasion resistance, providing excellent protection for the cables in marine environments and reducing damage caused by friction and vibration.

[0051] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
