Abstract
Description
Technical Field
[0001] This disclosure relates to the field of marine photovoltaic technology, and more specifically, to an integrated device for marine photovoltaic and communication. Background Technology
[0002] Given the abundance of resources in the ocean, current development of the ocean is far from sufficient. To improve ocean utilization, offshore power generation projects can be deployed on the sea. Offshore power generation includes offshore photovoltaic power generation systems, which can convert solar energy at sea into electricity, thereby providing users with ample power resources.
[0003] The core component of an offshore photovoltaic (PV) power generation system is the photovoltaic module, which converts solar energy into electrical energy and transmits it. To improve the utilization rate of solar energy by the PV modules, multiple sets of different PV modules are usually installed in a single marine area. These PV modules need to work together to achieve efficient power transmission. Currently, communication devices are commonly used to connect different PV modules to achieve data reception and transmission. However, these communication devices are often installed independently outside the PV modules. Such independent communication devices often have relatively low connection strength, poor integration with the PV modules, are easily damaged by the marine environment, and have a short service life.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0030] In related technologies, offshore power generation systems include offshore wind power generation and offshore photovoltaic power generation. Offshore photovoltaic power generation is a device that uses photovoltaic panels to convert solar energy into electrical energy. Since the sea has abundant solar energy resources, deploying photovoltaic power generation systems at sea is an effective means of utilizing clean energy.
[0031] To facilitate the layout and construction of offshore photovoltaic (PV) systems, PV modules are often laid out in designated zones. To enable data reception and transmission between PV modules in different zones or between different PV modules within the same zone, communication devices are typically installed on the PV modules. Currently, these communication devices are often independently located in areas near the PV modules, and communication between the modules is achieved through wireless communication. However, this method of setting up communication devices not only occupies offshore space, but also the independent connections of these communication devices often cannot withstand the effects of offshore conditions for extended periods, thus compromising their lifespan.
[0032] Based on this, the present disclosure provides an integrated device for marine photovoltaic and communication, such as... Figure 1 As shown, combined with Figures 2 to 3 The integrated device includes: photovoltaic modules 50, multiple communication base stations 10, and pole structure 20.
[0033] The photovoltaic modules 50 are installed in the main area, which includes multiple sub-photovoltaic areas. The photovoltaic modules 50 are laid on the sea surface through support units 51. Each sub-photovoltaic area includes at least one support unit 51, and the support unit 51 includes an operation and maintenance channel 30 for the maintenance of the photovoltaic modules 50. Each sub-photovoltaic area is equipped with at least one communication base station 10. The communication base stations 10 in adjacent sub-photovoltaic areas establish data transmission through a wireless communication network. The communication base station 10 is connected to the operation and maintenance channel 30 through a pole structure 20. The bottom end 201 of the pole structure is fixedly connected to the bottom surface 301 of the operation and maintenance channel, and the side 302 of the pole structure near the bottom end 201 is fixedly connected to the side 302 of the operation and maintenance channel. The communication base station 10 is located at the top end 202 of the pole structure, and the diameter of the bottom end 201 of the pole structure is larger than the diameter of the top end 202 of the pole structure.
[0034] The integrated device for marine photovoltaic and communication disclosed herein connects multiple communication base stations 10 to an operation and maintenance channel 30 via a pole structure 20. This enables communication between photovoltaic modules 50 in multiple different sub-photovoltaic areas or multiple different main areas. The pole structure 20 is fixed to the existing structure of the operation and maintenance channel 30, thus ensuring its secure connection within the marine photovoltaic system. The communication base stations 10 are then connected to the pole structure 20, improving the integration between the communication base stations 10 and the photovoltaic modules 50. The bottom end 201 of the pole structure is fixedly connected to the bottom surface 301 of the operation and maintenance channel, and the side 302 of the pole structure 20 near the bottom end 201 is fixedly connected to the side 302 of the operation and maintenance channel. This enhances the reliable connection of the communication base stations 10 within the marine photovoltaic system and prevents damage to the pole structure 20 from reducing the service life of the communication base stations 10. Furthermore, the pole structure 20 is simple and has high structural strength. Its top-narrow and bottom-wide structure ensures structural strength while improving economic efficiency.
[0035] In this disclosure, photovoltaic modules 50 are set in a main area, which includes multiple sub-photovoltaic areas. The shape and specific location of the main area can be determined and adjusted according to the actual design requirements of offshore photovoltaics. The number of sub-photovoltaic areas in the main area, as well as the positional relationship and area of adjacent sub-photovoltaic areas, can be determined according to actual design and usage requirements. For example, the area of each sub-photovoltaic area may be the same, or some sub-photovoltaic areas may have the same area, or the area of each sub-photovoltaic area may be different. For example, the main area may include two, three, four, five, or even more sub-photovoltaic areas. This disclosure does not make any specific limitations.
[0036] Photovoltaic modules 50 are laid on the sea surface via support units 51, such as Figure 3 As shown, the support unit 51 supports the photovoltaic module 50, which converts solar energy into electrical energy. The support unit 51 can be a grid structure assembled from multiple rods. One side of the support unit 51 is used to install the photovoltaic module 50, and the other side is connected to a pile foundation, which can be fixed to the seabed. The support unit 51 provides support and installation space for the photovoltaic module 50. Multiple support units 51 can be set up in a sub-photovoltaic area, and multiple photovoltaic modules 50 can be installed on one support unit 51. The number and layout of the photovoltaic modules 50 can be adaptively adjusted as needed. The specific structure and dimensions of the support unit 51 can be designed and improved according to actual design and usage requirements; the specific structure of the support unit 51 is not detailed here. In addition, offshore photovoltaic systems may also include other necessary components or devices for offshore power generation, which are not mentioned here.
[0037] The various parts of the integrated marine photovoltaic and communication device provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings:
[0038] In the embodiments provided in this disclosure, such as Figure 3 As shown, combined with Figure 1 The integrated device includes a photovoltaic module 50, which is set in a main area. The main area includes multiple sub-photovoltaic areas. The photovoltaic module 50 is laid on the sea surface through a support unit 51. Each sub-photovoltaic area includes at least one support unit 51. The support unit includes an operation and maintenance channel 30 for the maintenance of the photovoltaic module 50.
[0039] Each support unit 51 includes an operation and maintenance channel 30, which is integrated within the support unit 51 and serves to inspect and maintain the photovoltaic modules 50, inspect and maintain the cables, and cope with extreme weather conditions. It should be noted that the operation and maintenance channel 30 can be part of the support unit 51 or can be a separate structure integrated within the support unit 51. The operation and maintenance channel 30 can also be a structure composed of multiple rods with channels; for example, the operation and maintenance channel 30 can be a grid structure composed of multiple square steel members with channels. The specific structure and location of the operation and maintenance channel 30 can be determined according to actual design requirements. The operation and maintenance channel 30 provided in this disclosure includes operation and maintenance channels 30 applicable to various support units 51, and the specific structural form of the operation and maintenance channel 30 is not limited.
[0040] Each maintenance channel 30 may include a bottom surface 301 and a side surface 302. In this disclosure, the bottom surface 301 of the maintenance channel refers to the side of the maintenance channel 30 that is close to the sea surface and parallel or substantially parallel to the sea surface, or it may refer to the plane of the maintenance channel 30 that is close to the sea surface and has an angle with the sea surface. The side surface 302 of the maintenance channel refers to the side of the maintenance channel 30 that is perpendicular or substantially perpendicular to the sea surface, and the side surface 302 may be perpendicular to the ground or have an angle of less than 90° with the ground. In the embodiments of this disclosure, the example of the side surface 302 and the bottom surface 301 of the maintenance channel being perpendicular to each other is used for explanation. When the angle between the bottom surface 301 and the side surface 302 of the maintenance channel is less than 90°, the structure and arrangement of the pole structure 20 in the integrated device of this disclosure can be adaptively changed, all of which are within the protection scope of this disclosure.
[0041] In the embodiments provided in this disclosure, such as Figure 1 As shown, combined with Figure 3 The integrated device includes multiple communication base stations 10, with at least one communication base station 10 set in each sub-photovoltaic area. The communication base stations 10 in adjacent sub-photovoltaic areas establish data transmission through a wireless communication network.
[0042] The communication base station 10 can be a Mesh base station, relay base station, Small Cell base station, distributed base station, virtual base station, wireless access point, vehicle-mounted base station, drone base station, satellite base station, self-organizing network base station, and edge computing base station, etc. However, in the embodiments provided in this disclosure, the communication base station 10 is described using a Mesh base station as an example. But for other types of base stations, the structure of the device can be adapted to accommodate changes in the type of communication base station 10.
[0043] To ensure the reliability of wireless communication between adjacent sub-photovoltaic areas, at least one communication base station 10 is set up in each sub-photovoltaic area. For example, the number of communication base stations 10 in each sub-photovoltaic area can be one, two, three or even more. The number of communication base stations 10 can be determined according to parameters such as the area of each sub-photovoltaic area.
[0044] In the embodiments provided in this disclosure, the integrated device includes a pole structure 20, and each communication base station 10 is connected to the maintenance channel 30 through the pole structure 20. The pole structure 20 and the communication base station 10 can have a one-to-one correspondence; the communication base station 10 and the maintenance channel 30 can also have a one-to-one correspondence or a many-to-one relationship. However, to ensure the maximum utilization rate of the communication base station 10, typically one communication base station 10 is installed on one maintenance channel 30.
[0045] In some embodiments, the bottom end 201 of the pole structure is fixedly connected to the bottom surface 301 of the maintenance channel. The bottom end 201 of the pole structure is connected to the bottom surface 301 of the maintenance channel via a first connector 41, which limits the position of the pole structure 20 along its extension direction. Figure 2 As shown, combined with Figure 1 The first connecting member 41 can be a flange, having a central flange hole 401 and sub-flange holes 402 arranged circumferentially around the central flange hole 401. The bottom end 201 of the upright structure passes through and is fixed in the central flange hole 401, and the flange is fixedly connected to the bottom surface 301 of the maintenance channel through multiple sub-flange holes 402. The axis of the upright structure 20 and the axis of the first connecting member 41 are perpendicular or approximately perpendicular to the bottom surface 301 of the maintenance channel, respectively. Specifically, the bottom end 201 of the upright structure and the flange can be connected by interference fit, bonding, or bolting; the flange and the maintenance channel 30 can be connected by bolting, riveting, or bonding. The first connecting member 41 connects the upright structure 20 to the bottom surface 301 of the maintenance channel, limiting and fixing the upright structure 20 along its length to achieve initial connection between the upright structure 20 and the bottom surface 301 of the maintenance channel.
[0046] like Figure 1As shown, in order to limit the position of the upright structure 20 in a direction perpendicular to the upright structure 20, the integrated device also includes a second connector 42. One end of the second connector 42 is vertically connected to the bottom surface 301 of the maintenance channel, and the other end of the second connector 42 is vertically connected to the first connector 41. The second connector 42 is used to limit the position of the first connector 41 in a direction perpendicular to the upright structure 20, thereby limiting the position of the upright structure 20. For example, the second connector 42 can be a U-shaped clamp. After the upright structure 20 is connected to the bottom surface 301 of the maintenance channel (such as the square steel constituting the bottom surface 301) through the first connector 41, the U-shaped clamp is then connected to the side surface 302 of the first connector and the bottom surface 301 of the maintenance channel. By positioning the second connector 42 on the bottom surface 301 of the maintenance channel, the first connector 41 is limited, thereby achieving the purpose of limiting the position of the upright structure 20 in a direction perpendicular to the upright structure 20. It should be noted that the second connector 42 can also be a buckle, clamp or other structure. The number of the second connector 42 can be 1, 2, 3 or more. The number of the second connector 42 can be selected according to its own structural dimensions and the specific dimensions of the first connector 41, etc., to ensure that the second connector 42 limits the first connector 41.
[0047] like Figure 1 As shown, the integrated device also includes a plurality of third connectors 43, wherein the plurality of third connectors 43 are disposed on the side 302 of the upright structure 20 near the bottom end 201. In a direction parallel to the upright structure 20, the plurality of third connectors 43 are spaced apart on the upright structure 20, and each third connector 43 connects the upright structure 20 and the side 302 of the maintenance channel. The upright structure 20 is connected to the side 302 of the maintenance channel through the plurality of third connectors 43, thereby further fixing the upright structure 20 and improving the stability and support reliability of the upright structure 20.
[0048] The third connector 43 can be one of the following structures: a U-shaped clamp, a clip, or a buckle. Multiple third connectors 43 can effectively fix the pole structure 20 and the maintenance channel 30. The number of third connectors 43 can be 2, 3, 4, 5, or even more. The number of third connectors 43 can be selected according to the length of the pole structure 20 and the height of the side 302 of the maintenance channel, ensuring the reliability of the fixation of the bottom 201 of the pole structure. Specifically, multiple third connectors 43 are distributed at intervals along the height of the side 302 of the maintenance channel. Furthermore, the multiple third connectors 43 can be evenly distributed to ensure the uniformity of force on each third connector 43, thereby improving the connection reliability between the pole structure 20 and the maintenance channel 30.
[0049] In the embodiments provided in this disclosure, the diameter of the bottom end 201 of the upright structure is larger than the diameter of the top end 202 of the upright structure. The upright structure 20 may include a first main body portion 21 and a second main body portion 22, which are connected along the length of the upright structure 20. The first main body portion 21 includes the bottom end 201 of the upright structure, and the second main body portion 22 includes the top end 202 of the upright structure. The diameter of the first main body portion 21 is larger than the diameter of the second main body portion 22, and the length of the first main body portion 21 is smaller than the length of the second main body portion 22. This provides stable support to the bottom end 201 of the upright structure, while using a smaller diameter second main body portion 22 reduces the structural weight, facilitates the installation of the upright structure 20, and ensures the economic efficiency of the upright structure 20.
[0050] Specifically, to ensure the supporting performance of the first main body 21 and the installation performance of the second main body 22 on the communication base station 10, the length ratio of the first main body 21 to the second main body 22 can be 7:10 to 8:10. For example, the length of the first main body 21 can be 1500mm to 2000mm, and the length of the second main body 22 can be 2200mm to 2800mm. Specifically, the length of the first main body 21 can be 1800mm, and the length of the second main body 22 can be 2200mm. The ratio of the diameter of the first main body 21 to the diameter of the second main body 22 is 2:1 to 4:3. The diameter of the first main body 21 can be 110mm to 120mm, and the diameter of the second main body 22 can be 70mm to 80mm. Specifically, the diameter of the first main body 21 can be 114mm, and the diameter of the second main body 22 can be 76mm. This ensures the supporting strength of the pole structure 20 while improving economy.
[0051] In the embodiments provided in this disclosure, such as Figure 1 As shown, the integrated device also includes a base station frame 11, one side of which is connected to the side 302 of the pole structure. The communication base station 10 is installed inside the base station frame 11. The base station frame 11 is installed on the side of the second main body 22 and near the top 202 of the pole structure, ensuring the installation height of the communication base station 10, thereby ensuring the communication signal and signal coverage area of the communication base station 10, achieving comprehensive signal coverage among multiple communication base stations 10 and improving communication quality.
[0052] The base station frame 11 can be a frame structure made of multiple stainless steel rods. The shape of the base station frame 11 matches the shape of the communication base station 10, ensuring that the communication base station 10 can be assembled inside the base station frame 11. In addition, the base station frame 11 can be a hollow structure or a box structure. When the base station frame 11 is a box structure, a door structure needs to be set on the box to facilitate the assembly of the communication base station 10.
[0053] In the embodiments provided in this disclosure, the power of the communication base station 10 can be provided by the photovoltaic module 50. That is, after the photovoltaic module 50 converts solar energy into electrical energy, the voltage can be converted into a voltage matched to the communication base station 10 through a power conversion device, thereby providing power to the communication base station 10, further improving the integration of marine photovoltaic systems. Furthermore, as... Figure 1 As shown, in order to centrally manage and distribute weak current signals to the communication base station 10, the integrated device may further include a weak current box 60. The weak current box 60 is connected to both the communication base station 10 and the photovoltaic module 50. The weak current box 60 is used to convert the voltage generated by the photovoltaic module 50 to provide power to the communication base station 10. It should be noted that the weak current box 60 provided in this disclosure can be any structure or type of weak current box 60 available in the art. The specific weak current box 60 can be selected according to the usage requirements, and the specific structure of the weak current box 60 will not be described in detail here.
[0054] To ensure the positional relationship between the low-voltage box 60 and the communication base station 10 meets operational requirements, the low-voltage box 60 can be installed at the top 202 of the pole structure, i.e., the low-voltage box 60 is installed on the second main body 22, and the communication base station 10 and the low-voltage box 60 are sequentially arranged along the direction from the top 202 to the bottom 201 of the pole structure. The integrated device also includes a first extension member 44, which is installed perpendicular to the pole structure 20, with one end connected to the pole structure 20 and the low-voltage box 60 mounted on the other end of the first extension member 44. The first extension member 44 can be a crossbar or crossbeam, and there can be multiple first extension members 44 to meet the installation requirements of the low-voltage box 60. Specifically, the first extension 44 can be a crossarm, which is set along the length direction perpendicular to the upright structure 20. There are two crossarms, one end of each of the two crossarms is connected to the upright structure 20, and the other end extends along the length direction perpendicular to the upright structure 20. The low-voltage box 60 is mounted on the two crossarms, and the other end of the crossarms is fixed to the other end of the upright structure 20 by a clamp to limit the position of the low-voltage box 60.
[0055] The pole structure 20, the first connector 41, the second connector 42, the third connector 43, the base station frame 11, the first extension 44 and other structures provided in this disclosure can all be made of metal materials, such as stainless steel or aluminum alloy, which ensures the structural strength, connection reliability and support reliability of each component, thereby improving the structural strength and stability.
[0056] The integrated device for marine photovoltaic and communication disclosed herein connects multiple communication base stations 10 to an operation and maintenance channel 30 via a pole structure 20. This enables communication between photovoltaic modules 50 in multiple different sub-photovoltaic areas or multiple different main areas. The pole structure 20 is fixed to the existing structure of the operation and maintenance channel 30, thus ensuring its secure connection within the marine photovoltaic system. The communication base stations 10 are then connected to the pole structure 20, improving the integration between the communication base stations 10 and the photovoltaic modules 50. The bottom end 201 of the pole structure is fixedly connected to the bottom surface 301 of the operation and maintenance channel, and the side 302 of the pole structure 20 near the bottom end 201 is fixedly connected to the side 302 of the operation and maintenance channel. This enhances the reliable connection of the communication base stations 10 within the marine photovoltaic system and prevents damage to the pole structure 20 from reducing the service life of the communication base stations 10. Furthermore, the pole structure 20 is simple and has high structural strength. Its top-narrow and bottom-wide structure ensures structural strength while improving economic efficiency.
