[0001] This invention relates to the field of offshore photovoltaic power generation technology, specifically to an offshore photovoltaic platform body and a floating offshore photovoltaic platform that facilitates the assembly and disassembly of photovoltaic modules. Background Technology

[0002] Currently, solar power plants are mainly concentrated on land, requiring a large land area. To address this land issue, floating offshore photovoltaic (PV) platforms have seen rapid development. To improve power generation efficiency, these platforms typically deploy hundreds of PV modules, resulting in a large installation area. However, given the relatively weak strength of PV modules, stepping on adjacent modules during installation and removal makes this process difficult and inefficient. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a marine photovoltaic platform body that facilitates the assembly and disassembly of photovoltaic modules, which has the advantage of convenient assembly and disassembly of photovoltaic modules.

[0006] The main body of the offshore photovoltaic platform for easy assembly and disassembly of photovoltaic modules according to an embodiment of the present invention includes an upper frame, a mounting sleeve, a first drive module, a second drive module, and an electric suction cup. An electronic control system is provided at the center of the upper surface of the upper frame, and photovoltaic modules surrounding the electronic control system are laid on the upper surface of the upper frame. The mounting sleeve is installed above the upper frame and surrounds the electronic control system.

[0007] According to an embodiment of the present invention, the main body of an offshore photovoltaic platform for easy installation and removal of photovoltaic modules includes a first drive module pivotally connected to the mounting sleeve around its central axis, and a second drive module mounted on the first drive module. This allows the second drive module to move to any side of the mounting sleeve and radially along the mounting sleeve to any position above the upper frame. When installation or removal of the photovoltaic modules is required, simply drive the first drive module to rotate around the mounting sleeve. The first drive module then drives the second drive module to move radially along the mounting sleeve, moving the electric suction cup above the photovoltaic module's placement or installation position. The second drive module then drives the electric suction cup downwards to attract the photovoltaic module. Repeating the operation of the first and second drive modules moves the photovoltaic module to the designated position, completing the installation or removal of the photovoltaic module. The entire process requires no manual handling of the photovoltaic modules and does not compress other photovoltaic modules.

[0012] In some embodiments, the upper surface of the upper frame is provided with a plurality of mounting slots, each mounting slot corresponding to a photovoltaic module, and the mounting slots are for the corresponding photovoltaic modules to cooperate with.

[0013] The main body of the offshore photovoltaic platform for easy assembly and disassembly of photovoltaic modules also includes a locking member and an elastic member. The locking member is pivotally connected to the upper frame. The locking member has a clearance position located beside the mounting slot and a locking position located inside or above the mounting slot. The locking member located in the locking position is adapted to press the frame of the photovoltaic module. The elastic member connects the locking member and the upper frame and presses the locking member toward the locking position.

[0014] In some embodiments, the upper frame includes a plurality of longitudinal ribs spaced apart along a first direction and a plurality of transverse ribs spaced apart along a second direction, wherein the first direction, the second direction, and the height direction are perpendicular to each other, and the plurality of longitudinal ribs and the plurality of transverse ribs are arranged intersectingly and surrounding to form a plurality of mounting grooves, and all the locking members are pivotally connected to the longitudinal ribs.

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following is combined Figures 1-4 This invention describes the main body of an offshore photovoltaic platform that facilitates the assembly and disassembly of photovoltaic modules according to an embodiment of the present invention.

[0027] The main body of the offshore photovoltaic platform for easy assembly and disassembly of photovoltaic modules according to an embodiment of the present invention includes an upper frame 1, a mounting sleeve 2, a first drive module 6, a second drive module 7, and an electric suction cup 8. An electronic control system 120 is located at the center of the upper surface of the upper frame 1, and photovoltaic modules 130 are laid around the electronic control system 120 on the upper surface of the upper frame 1. The mounting sleeve 2 is mounted above the upper frame 1 and surrounds the electronic control system 120. The first drive module 6 is pivotally connected to the mounting sleeve 2 about its central axis. The second drive module 7 is mounted on the first drive module 6 and is adapted to reciprocate radially along the mounting sleeve 2. The electric suction cup 8 is mounted on the second drive module 7 and is adapted to reciprocate vertically.

[0028] According to an embodiment of the present invention, the main body of the offshore photovoltaic platform for easy installation and removal of photovoltaic modules includes a first drive module 6 pivotally connected to the mounting sleeve 2 around its central axis. A second drive module 7 is mounted on the first drive module 6, thereby allowing the second drive module 7 to move to any side of the mounting sleeve 2 and radially move above any position of the upper frame 1. When it is necessary to install or remove the photovoltaic module 130, simply drive the first drive module 6 to rotate around the mounting sleeve 2. The first drive module 6 drives the second drive module 7 to move radially along the mounting sleeve 2, so that the electric suction cup 8 moves above the placement or installation position of the photovoltaic module 130. Then, the second drive module 7 drives the electric suction cup 8 to move down and suction the photovoltaic module 130. Subsequently, the first drive module 6 and the second drive module are driven repeatedly to move the photovoltaic module 130 to the set position, completing the installation or removal of the photovoltaic module 130. The entire process does not require manual handling of the photovoltaic module 130, nor does it compress other photovoltaic modules 130. The installation and removal of the photovoltaic module 130 is convenient and safe.

[0029] It should be noted that when it is necessary to disassemble the photovoltaic module 130, the connection between the photovoltaic module 130 and the upper frame 1 must be disconnected before the aforementioned electric suction cup 8 can be used to disassemble the photovoltaic module 130. Furthermore, as... Figure 1 As shown, the main body of the offshore photovoltaic platform, which facilitates the assembly and disassembly of photovoltaic modules, also includes a lower frame 9 and a column 10. The column 10 is connected between the upper frame 1 and the lower frame 9 in the height direction. The lower frame 9 and the column 10 are provided with a float 110 at their lower ends. The main body of the offshore photovoltaic platform floats on the sea surface through the float 110, so that the upper frame 1 and the photovoltaic modules 130 are higher than the sea surface by a certain height.

[0030] In some embodiments, such as Figure 3 As shown, the main body of the offshore photovoltaic platform that facilitates the assembly and disassembly of photovoltaic modules also includes a gear ring 4, a first motor 3, and a gear 5. The gear ring 4 is pivotally fitted around the central axis of the mounting sleeve 2 on the outside of the mounting sleeve 2. The first drive module 6 is connected to the gear ring 4. The first motor 3 is installed on the mounting sleeve 2. The motor shaft of the first motor 3 is coaxially connected to the gear 5, and the gear 5 meshes with the gear ring 4.

[0031] That is, the first motor 3 drives the first drive module 6 through the transmission mechanism formed by the gear ring 4 and the gear 5, ensuring that the first drive module 6 can automatically rotate 360°, and the movement of the electric suction cup 8 is more labor-saving.

[0032] Specifically, the outer circumferential surface of the mounting sleeve 2 is provided with an annular guide groove. The gear ring 4 includes an annular plate and multiple straight teeth disposed on the lower surface of the annular plate. A portion of the annular plate is rotatably fitted into the annular guide groove, and the multiple straight teeth are located on the outer circumferential side of the mounting sleeve 2. The first motor 3 is mounted on the inner side of the mounting sleeve 2. The motor shaft of the first motor 3 passes through the mounting sleeve 2 and is connected to a gear 5 located outside the mounting sleeve 2. The gear 5 is located below the gear ring 4 and meshes with the gear ring 4.

[0033] Alternatively, the first drive module 6 can be manually pushed to complete the rotation of the first drive module 6 around the mounting sleeve 2.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, the first drive module 6 includes a guide rail, a second motor, a lead screw, and a slider. The guide rail extends radially along the mounting sleeve 2, and the first end of the guide rail is connected to the gear ring 4. The second motor is mounted on the first end of the guide rail. The lead screw extends radially along the mounting sleeve 2 and is coaxially connected to the motor shaft of the second motor. The slider is threadedly engaged with the lead screw and is slidably connected to the guide rail along the radial direction of the mounting sleeve 2. The slider is connected to the second drive module 7.

[0035] At this time, the second motor drives the lead screw to rotate, which in turn drives the slider to slide back and forth along the radial direction of the mounting sleeve 2 relative to the guide rod, so as to realize the movement of the electric suction cup 8 at any position along the radial direction of the mounting sleeve 2, which is convenient and reliable.

[0036] Specifically, the slider is slidably positioned below the guide rail, and the end of the lead screw furthest from the second motor is rotatably mounted on the guide rail around its axis.

[0037] In some embodiments, the second drive module 7 includes a push rod motor, which is mounted on the slider, and the push rod of the push rod motor extends in the height direction and is connected to the electric suction cup 8.

[0038] The push rod motor can move the electric suction cup 8 to any position along the height direction, ensuring that the electric suction cup 8 can be tightly attached to the upper surface of the photovoltaic module 130, while also effectively avoiding excessive pressure on the photovoltaic module 130 from the electric suction cup 8, which could damage the photovoltaic module 130, thus effectively ensuring the reliability of the installation and removal of the photovoltaic module 130.

[0039] It should be noted that the electronic control system 120 includes a battery for collecting electrical energy generated by the photovoltaic module 130. The first motor 3, the second motor and the push rod motor are all powered by the battery, eliminating the need for an additional power supply. This effectively reduces power supply costs while ensuring that the three motors can operate virtually indefinitely, further guaranteeing the reliability of the photovoltaic module 130 during installation and removal.

[0040] In some embodiments, such as Figure 1As shown, a fence 16 is provided above the upper frame 1, surrounding all photovoltaic modules 130. A slide rail is formed on the fence 16, extending circumferentially along the mounting sleeve 2 and connected end to end. The slide rail forms an annular groove with the opening facing upward. A roller is provided at the second end of the guide rail, and the roller rolls and engages in the annular groove.

[0041] The slide rail on the fence 16 provides support for the second end of the guide rail, effectively preventing the guide rail, its push rod motor, electric suction cup 8, and photovoltaic module 130 from becoming tilted due to excessive weight. This effectively improves the service life of the photovoltaic module 130 installation and removal device. At the same time, the rolling cooperation between the roller and the annular slide groove effectively reduces the friction between them, ensuring that the rotation of the guide rail along the circumference of the mounting sleeve 2 is effortless and reliable.

[0042] In some embodiments, such as Figure 4 As shown, the upper surface of the upper frame 1 is provided with multiple mounting slots 13, each corresponding to a photovoltaic module 130, and the mounting slots 13 are for the corresponding photovoltaic module 130 to mate with. The main body of the offshore photovoltaic platform, which facilitates the installation and removal of photovoltaic modules, also includes locking components and elastic components. The locking components are pivotally connected to the upper frame 1. The locking components have a clearance position located beside the mounting slot 13 and a locking position located inside or above the mounting slot 13. The locking components located in the locking position are suitable for pressing the frame of the photovoltaic module 130. The elastic components connect the locking components and the upper frame 1, and the elastic components press the locking components toward the locking position.

[0043] Therefore, when it is necessary to install the photovoltaic module 130, the locking member is moved to a position that avoids the mounting groove 13. Then, the photovoltaic module 130 is placed in the mounting groove 13. After that, the control of the locking member is released. Under the action of the elastic member, the locking member is partially located above the mounting groove 13 and abuts against the upper surface of the frame of the photovoltaic module 130, or partially located in the mounting groove 13 and pressed against the outer periphery of the frame of the photovoltaic module 130. This achieves the locking of the photovoltaic module 130. The entire installation process is completed above the upper frame 1, which further improves the installation efficiency of the photovoltaic module 130 on the upper frame 1.

[0044] In some embodiments, such as Figure 4 As shown, the upper frame 1 includes a plurality of longitudinal ribs 12 spaced apart along a first direction and a plurality of transverse ribs 11 spaced apart along a second direction. The first direction, the second direction and the height direction are perpendicular to each other. The plurality of longitudinal ribs 12 and the plurality of transverse ribs 11 are arranged intersectingly and surround to form a plurality of mounting grooves 13. All locking elements are pivotally connected to the longitudinal ribs 12.

[0045] Multiple horizontal ribs 11 and multiple vertical ribs 12 are welded together to form the sides of multiple rectangular mounting slots 13 of roughly the same size. At this time, by pivoting the locking parts onto the vertical ribs 12, there is no need to design the horizontal ribs 11 for the installation of locking parts. The structure of the horizontal ribs 11 is simpler and the manufacturing cost of the upper frame 1 is lower.

[0046] Specifically, multiple longitudinal ribs 12 are arranged at equal intervals in the first direction, and multiple transverse ribs 11 are arranged at equal intervals in the second direction. The photovoltaic module 130 installed in the mounting groove 13 is locked and limited only by locking members on opposite sides in the first direction, so as to complete the reliable installation of the photovoltaic module 130 on the upper frame 1.

[0047] In some embodiments, the main body of the offshore photovoltaic platform that facilitates the assembly and disassembly of photovoltaic modules also includes tie rods, which correspond one-to-one with the longitudinal ribs 12. The tie rods are slidably connected to the longitudinal ribs 12 along the second direction, and the tie rods are also pivotally connected to all locking elements on the corresponding longitudinal ribs 12.

[0048] Therefore, by pulling two adjacent tie rods along the extension direction of the longitudinal rib 12, the locking parts corresponding to all the mounting slots 13 between the two tie rods can be switched to the avoidance position, which facilitates the installation of the photovoltaic module 130 in this part of the mounting slot 13, and the installation efficiency of the photovoltaic module 130 on the upper frame 1 is higher.

[0049] Specifically, by setting a pull rod, the locking component can be switched to the avoidance position without the staff having to approach the locking component next to the corresponding mounting slot 13, making the installation and removal of the photovoltaic module 130 convenient and quick.

[0050] In some embodiments, such as Figure 4 As shown, the upper frame 1 also includes a support plate 14 forming the bottom surface of the mounting groove 13. The support plate 14 is provided with a through hole 15 extending in the height direction. A first channel is defined between the support plate 14 and the photovoltaic module 130. A second channel is defined between the outer peripheral surface of the photovoltaic module 130 and the side surface of the mounting groove 13, extending in the height direction to the upper surface of the upper frame 1. The first channel connects the second channel and the through hole 15.

[0051] Therefore, the air below the upper frame 1 can communicate with the air above the upper frame 1 through the through hole 15, the first channel and the second channel, thereby effectively preventing the photovoltaic module 130 from being loosened or even detached from the upper frame 1 due to excessive pressure difference from the height direction, and effectively improving the service life of the photovoltaic module 130.

[0052] Specifically, the upper surface of the tray 14 is provided with a first through groove, which surrounds the lower surface of the photovoltaic module 130 to form a first channel. The side of the mounting groove 13 is provided with a second through groove extending in the height direction, which surrounds the periphery of the photovoltaic module 130 to form a second channel.
