Description

Technical Field

[0001] This invention relates to the field of photovoltaic construction technology, specifically a fixed offshore photovoltaic construction device. Background Technology

[0002] Offshore photovoltaic (PV) construction mainly employs two structures: pile-based fixed type and floating type. In nearshore areas with shallow water depth (usually less than 5 meters), pile-based fixed type is mostly used, which involves driving steel pipe piles into the seabed and then installing PV brackets and modules.

[0003] Existing photovoltaic (PV) installation equipment typically includes cooling channels at the top of the solar panels during assembly and power generation to ensure proper heat dissipation during long-term operation. However, since PV operations take place at sea, maintenance and cleaning are challenging. The power generation modules in the middle section of the panel have limited contact area with the sea breeze. When debris from the shore or seabird droppings fall onto this middle section, it severely impacts the power generation efficiency and effectiveness of the internal modules. Summary of the Invention

The photovoltaic heat dissipation structure includes: a photovoltaic module mounted on the top of the mounting disk by screws; a detachable assembly component snapped onto one side of the top of the photovoltaic module; and a tapered guide component snapped onto the top of the detachable assembly component and matching the photovoltaic module. The tapered guide component guides and transmits natural airflow into the interior of the photovoltaic module and performs heat dissipation treatment on the photovoltaic module. The photovoltaic module is arranged at an angle, and the tapered guide component is installed on the higher side of the photovoltaic module arranged at an angle.

[0006] As a preferred embodiment of the present invention, the pre-assembled structure includes: Two metal retaining rings are provided, each abutting against one side of the top of the offshore steel support, and the two metal retaining rings are connected and fixed by screws. A vertical support body is snapped and fixed to the side of the extending protrusion block. The vertical support body is welded and fixed to the center of the side of the metal fixing ring. The vertical support body is made of high-strength steel. The vertical support body has extension assembly blocks welded and fixed on both sides of its top, and an installation disc is fixed to the top of the extension assembly blocks by screws.

[0007] In a preferred embodiment of the present invention, the mounting disc comprises a lower base plate, a middle plate, and a top mounting base. The lower base plate is mounted on the top of the extension assembly block by screws. The middle plate is fixedly mounted on the top of the lower base plate by screws. Mounting bases are welded and fixed to both sides of the top of the middle plate. The top of the mounting base is set as an inclined surface, and the photovoltaic module is fixed to the top of the mounting base by screws.

[0008] As a preferred embodiment of the present invention, the photovoltaic module includes: A photovoltaic panel is mounted on the top of the mounting base by screws. Multiple photovoltaic power generation modules are installed inside the photovoltaic panel, and the multiple photovoltaic power generation modules are connected in parallel. The recessed portion is formed inside the photovoltaic panel and is disposed on the side of multiple photovoltaic power generation modules. Multiple recessed portions are provided and form a mesh structure.

[0009] In a preferred embodiment of the present invention, the top of the photovoltaic power generation module is provided with multiple vertical grooves, which enable the photovoltaic power generation module to achieve rapid heat dissipation. The photovoltaic panel has a detachable assembly component installed on the outer side of its top by screws.

[0010] As a preferred embodiment of the present invention, the detachable assembly includes: A concave embedding frame is installed on the outer side of the top of the photovoltaic panel by screws, and an assembly bracket is installed and fixed on the inner side of the concave embedding frame; A vertical upper protrusion is installed on the top of the assembly bracket body. Multiple vertical upper protrusions are provided, and a gap is left between two adjacent vertical upper protrusions. An upper inclined surface is provided on the top of the assembly bracket body. Multiple upper inclined surfaces are provided, and the upper inclined surface is provided between two adjacent vertical upper protrusions.

[0011] As a preferred embodiment of the present invention, the top end of the upper inclined surface is disposed on the side of the vertical groove, and the top of the vertical upper protrusion is engaged and fixed with a tapered guide assembly.

[0012] As a preferred embodiment of the present invention, the tapered guide assembly includes: A tapered guide component, wherein an inner embedded block is installed on the inner side of the tapered guide component, and the tapered guide component is fixed to the top of the vertical upper protrusion by the inner embedded block; The tapered guide component has arc-shaped surfaces on its left and right sides.

[0013] As a preferred embodiment of the present invention, the arcuate surface of the tapered guide component is disposed on the side of the vertical groove, and the arcuate surface of the tapered guide component is disposed on the top of the upper inclined surface.

[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In fixed offshore photovoltaic construction equipment, airflow from the marine environment transmitted to the photovoltaic panels can be guided and transmitted. This ensures that the airflow for heat dissipation at sea can be concentrated and transmitted to the vertical grooves on the photovoltaic power generation module through two trumpet-shaped conical guide components. This concentrates the airflow through the heat dissipation channels (vertical grooves) generated during the photovoltaic power generation operation, improving the heat dissipation effect on each power generation unit inside the photovoltaic power generation module. At the same time, it expands the path length for airflow to move (flow) within the vertical grooves inside the photovoltaic power generation module, ensuring that the airflow can be concentrated to treat the photovoltaic power generation module (on the photovoltaic panel) located in the middle. When impurities (including but not limited to: seabird droppings) adhere to the surface of the photovoltaic panel, it is easier to remove the impurities (including but not limited to: seabird droppings), ensuring the stability and efficiency of offshore photovoltaic power generation operations. 2. In fixed offshore photovoltaic (PV) installations, by constructing PV power generation modules (on PV panels) within the marine environment and setting the PV power generation modules (on PV panels) for solar power generation on an inclined plane, the duration of solar radiation on the PV power generation modules (on PV panels) can be increased, thereby improving the efficiency and capacity of solar power generation. Furthermore, the effect of airflow transmission to the PV power generation modules (on PV panels) can be improved, enhancing the heat dissipation capacity and effectiveness of the PV power generation modules (on PV panels) during power generation operation. 3. In fixed offshore photovoltaic construction equipment, the structure allows for simple and convenient installation and disassembly of photovoltaic panels and conical guide components. This ensures that the disassembly and installation of photovoltaic panels and conical guide components can be completed quickly during cleaning (and after cleaning), thus guaranteeing sustainable solar photovoltaic power generation.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] Please see Figures 1-9 A fixed offshore photovoltaic (PV) construction device includes an offshore steel support column 10; a pre-assembled structure 20 installed on the outer side of the top of the offshore steel support column 10; an mounting disc 30 installed on the top of the pre-assembled structure 20 by screws; and a PV guiding and heat dissipation structure 40 installed on the top of the mounting disc 30 by screws. The PV guiding and heat dissipation structure 40 includes: a PV module 401 installed on the top of the mounting disc 30 by screws; a detachable assembly component 402 snapped and fixed to one side of the top of the PV module 401; and a conical guide component 403 snapped and fixed to the top of the detachable assembly component 402 and matching the PV module 401. The conical guide component 403 guides and transmits natural wind to the interior of the PV module 401 and performs heat dissipation treatment on the PV module 401. The PV module 401 is obliquely arranged, and the conical guide component 403 is installed on the higher side of the obliquely arranged PV module 401.

[0020] The working principle is as follows: When conducting offshore solar power generation operations, a pre-embedded (fixed) offshore steel support column 10 is first erected at sea (within the coastal area). An installation disc 30 is then installed on top of the offshore steel support column 10 via a pre-assembly structure 20, and a photovoltaic module 401 is installed on top of the installation disc 30. The photovoltaic module 401 then converts solar energy and generates electricity. During actual solar power generation, a detachable assembly component 402 and a conical guide component 403 can be installed on the side of the photovoltaic module 401. The conical guide component 403 guides and transports the airflow blowing onto the photovoltaic module 401, ensuring that the airflow is uniformly and stably transmitted to the interior of the photovoltaic module 401. It also treats impurities (including but not limited to seabird droppings) adhering to the photovoltaic module 401, reducing the probability of impurities (including but not limited to seabird droppings) accumulating and adhering to the surface of the photovoltaic module 401 while ensuring the contact area between the airflow and the photovoltaic module 401, thus guaranteeing the power generation effect and capacity of the photovoltaic module 401.

[0021] For details, please refer to the following: Figure 4 , Figure 5and Figure 6 The pre-assembled structure 20 includes two metal fixing rings 201, which abut against the top of the marine steel support 10 on both sides and are fixed together by screws. A vertical support body 202 is snapped onto the side of the extension protrusion 203 and welded to the center of the side of the metal fixing rings 201. The vertical support body 202 is made of high-strength steel. Extension assembly blocks 204 are welded to both sides of the top of the vertical support body 202, and an installation disc 30 is fixed to the top of the extension assembly blocks 204 by screws.

[0022] In the fixed offshore photovoltaic construction device of the present invention, when assembling the mounting disc 30, the metal fixing ring 201 is first placed against both sides of the top of the offshore steel support column 10, and the metal fixing ring 201 is installed and fixed to the outside of the offshore steel support column 10 by screws. Then, the vertical support body 202 is installed on the extended protrusion 203 on the outside of the metal fixing ring 201 by snap-fit, and the mounting disc 30 is installed and fixed by the extended assembly blocks 204 on both sides of the top of the vertical support body 202.

[0023] For details, please refer to the following: Figure 5 The mounting disc 30 consists of a lower base plate 301 at the bottom, a middle plate 302 in the middle, and a mounting base 303 at the top. The lower base plate 301 is mounted on the top of the extension assembly block 204 by screws. The middle plate 302 is fixedly mounted on the top of the lower base plate 301 by screws. The mounting bases 303 are welded and fixed on both sides of the top of the middle plate 302. The top of the mounting base 303 is set as an inclined surface, and the photovoltaic module 401 is fixedly mounted on the top of the mounting base 303 by screws.

[0024] In the fixed offshore photovoltaic construction device of the present invention, the design of the mounting base 303 structure can ensure that the photovoltaic module 401 is in an inclined state after installation, avoiding rainwater accumulation on the surface of the photovoltaic module 401, and ensuring the contact area between the airflow and the photovoltaic module 401.

[0025] For details, please refer to the following: Figure 7 and Figure 8 The photovoltaic module 401 includes a photovoltaic panel 4011, which is mounted on the top of the mounting base 303 by screws. Multiple photovoltaic power generation modules 4012 are installed inside the photovoltaic panel 4011 and are connected in parallel. There is also a recess 4013, which is formed inside the photovoltaic panel 4011 and is located on the side of the multiple photovoltaic power generation modules 4012. Multiple recesses 4013 are provided and form a mesh structure.

[0026] In this solution, the top of the photovoltaic power generation module 4012 is provided with multiple vertical grooves 40121. The photovoltaic power generation module 4012 achieves rapid heat dissipation through the vertical grooves 40121. The outer side of the top of the photovoltaic panel 4011 is equipped with a detachable assembly component 402 by screws.

[0027] In the fixed offshore photovoltaic construction device of the present invention, when solar power generation is carried out, multiple parallel photovoltaic power generation modules 4012 can absorb sunlight and convert it into electrical energy, which is then transmitted to an energy storage device connected to the photovoltaic panel 4011. The design of the recessed portion 4013 allows for the independent space of each photovoltaic power generation module 4012, ensuring that the power generation of each module (due to high temperatures) does not interfere with each other. The design of the vertical groove 40121 isolates each photovoltaic unit on the photovoltaic power generation module 4012, ensuring effective heat dissipation for each unit without affecting power generation efficiency.

[0028] For details, please refer to the following: Figure 7 , Figure 8 and Figure 9 The detachable assembly component 402 includes a concave embedding frame 4021, which is installed on the outer side of the top of the photovoltaic panel 4011 by screws, and an assembly bracket body 4022 is installed and fixed on the inner side of the concave embedding frame 4021; a vertical upper protrusion 4023, which is installed on the top of the assembly bracket body 4022, and multiple vertical upper protrusions 4023 are provided, with a gap between two adjacent vertical upper protrusions 4023; and an upper inclined surface 4024, which is provided on the top of the assembly bracket body 4022, and multiple upper inclined surfaces 4024 are provided, with the upper inclined surface 4024 located between two adjacent vertical upper protrusions 4023.

[0029] In this design, the top of the upper inclined surface 4024 is located on the side of the vertical groove 40121, and the top of the vertical upper protrusion 4023 is fixedly engaged with the tapered guide assembly 403.

[0030] In the fixed offshore photovoltaic construction device of the present invention, each conical guide component 403 can be assembled and fixed by installing the vertical upper protrusion 4023. The design of the upper inclined surface 4024 structure allows airflow to be transmitted through the inclined surface of the upper inclined surface 4024 to the interior of the vertical groove 40121, cleaning impurities adsorbed inside the vertical groove 40121. At the same time, it increases the path length of airflow within the vertical groove 40121, ensuring effective heat dissipation for the photovoltaic power generation module 4012 in the middle part (photovoltaic panel 4011).

[0031] For details, please refer to the following: Figure 7 , Figure 8 and Figure 9The tapered guide assembly 403 includes a tapered guide component 4031, an inner insert block 4032 is installed on the inner side of the tapered guide component 4031, and the tapered guide component 4031 is snapped and fixed to the top of the vertical upper protrusion 4023 by the inner insert block 4032; wherein, the left and right sides of the tapered guide component 4031 are provided with arc-shaped surfaces 4033, the arc-shaped surfaces 4033 are recessed into one side of the inner insert block 4032, and the recessed part of the arc-shaped surfaces 4033 is the top.

[0032] In this design, the arc-shaped surface 4033 of the tapered guide component 4031 is disposed on the side of the vertical groove 40121, and the arc-shaped surface 4033 of the tapered guide component 4031 is disposed on the top of the upper inclined surface 4024.

[0033] In the fixed offshore photovoltaic construction device of the present invention, the design of the conical guide component 4031 allows airflow to be transmitted through the arc-shaped surface 4033 to the interior of the vertical groove 40121, achieving concentrated airflow transmission. Furthermore, the trumpet shape formed by the two conical guide components 4031 expands and concentrates the transmission of airflow from the marine environment, making it more convenient and focused to transmit the airflow to the photovoltaic panel 4011, thus enhancing the airflow's ability and effectiveness in cleaning impurities from the surface of the photovoltaic panel 4011.
