Description

Technical Field

[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. Background Technology

[0002] Currently, solar power plants are mainly concentrated on land, requiring a large land area. To address this issue, floating offshore photovoltaic (PV) platforms have seen rapid development. To improve power generation efficiency, floating offshore PV platforms typically deploy hundreds of PV modules, resulting in a large installation area. However, given the complex marine environment, sufficient connection strength is required between the PV modules and the platform body. In related technologies, PV modules are usually fixed to the upper frame of the platform body using straps or threaded fasteners. Furthermore, to prevent the straps or threaded fasteners from blocking sunlight and affecting the power generation efficiency of the PV modules, they are often located below the PV modules. This requires workers to install the PV modules on the upper frame from below, resulting in low installation efficiency. 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 has the advantage of high installation efficiency of photovoltaic modules.

[0009] In some embodiments, each of the longitudinal ribs is pivotally provided with a plurality of the locking elements, and each of the mounting slots corresponds to at least three of the locking elements.

[0013] In some embodiments, the longitudinal rib has a receiving cavity extending along the second direction, the longitudinal rib is provided with a clearance hole communicating with the receiving cavity and the mounting groove, the locking member located in the clearance position is located in the receiving cavity, and the locking member located in the locking position protrudes from the clearance hole portion into the mounting groove.

[0014] In some embodiments, the transverse ribs are provided with a plurality of ventilation holes spaced apart along the first direction.

[0015] In some embodiments, the upper frame further includes a support plate forming the bottom surface of the mounting groove, the support plate having a through hole extending in the height direction, a first channel defining a space between the support plate and the photovoltaic module, and a second channel extending in the height direction to the upper surface of the upper frame defining a space between the outer peripheral surface of the photovoltaic module and the side surface of the mounting groove, the first channel connecting the second channel and the through hole.

[0023] 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.

[0024] The following is combined Figures 1-3 The main body of the offshore photovoltaic platform according to an embodiment of the present invention is described.

[0025] The main body of the offshore photovoltaic platform according to this embodiment of the invention includes an upper frame 1, a locking member, and an elastic member. The upper surface of the upper frame 1 is provided with multiple mounting slots 13, each corresponding to a photovoltaic module 2, and the mounting slots 13 are for the corresponding photovoltaic module 2 to mate with. The locking member is pivotally connected to the upper frame 1, and has a clearance position located beside the mounting slot 13 and a locking position located inside or above the mounting slot 13. The locking member in the locking position is suitable for pressing against the frame of the photovoltaic module 2. The elastic member connects the locking member and the upper frame 1, and the elastic member presses against the locking member towards the locking position.

[0026] According to an embodiment of the present invention, the upper surface of the offshore photovoltaic platform has mounting slots 13 equal in number to the number of photovoltaic modules 2. A locking member is pivotally connected to the upper frame 1, and under the pressure of an elastic member, the locking member has a locking position partially located above or inside the mounting slots 13. Thus, when it is necessary to install the photovoltaic modules 2, the locking member is controlled to move to a position that avoids the mounting slots 13. Then, the photovoltaic modules 2 are placed in the mounting slots 13. Subsequently, the control of the locking member is released, and under the action of the elastic member, the locking member is partially located above the mounting slots 13 and abuts against the upper surface of the frame of the photovoltaic modules 2, or partially located inside the mounting slots 13 and pressed against the outer periphery of the frame of the photovoltaic modules 2, thereby locking the photovoltaic modules 2. The entire installation process is completed above the upper frame 1, resulting in high installation efficiency of the photovoltaic modules 2 on the upper frame 1.

[0027] It should be noted that when the locking position of the locking component is partially located within the mounting groove 13, it is preferable to provide a limiting groove on the outer periphery of the frame of the photovoltaic module 2. When the locking component is in the locking position, it partially engages with the limiting groove, thereby effectively improving the installation strength of the photovoltaic module 2 on the upper frame 1. In addition, the main body of the offshore photovoltaic platform also includes a lower frame 4 and a column 3. The column 3 is connected between the upper frame 1 and the lower frame 4 in the height direction. The lower frame 4 and the column 3 are provided with a float 5 at their lower ends. The main body of the offshore photovoltaic platform floats on the sea surface through the float 5, so that the upper frame 1 and the photovoltaic module 2 are higher than the sea surface by a certain height.

[0028] In some embodiments, such as Figure 2 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 the side of forming a plurality of mounting grooves 13. The locking member is pivotally connected to the longitudinal ribs 12.

[0029] 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.

[0030] 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 2 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 2 on the upper frame 1.

[0031] It should be noted that, such as Figure 1 and Figure 2 As shown, the outer contour of the upper frame 1 is a regular hexagon. The upper frame 1 also includes multiple intersecting support ribs, which are welded below multiple longitudinal ribs 12 and transverse ribs 11.

[0032] In some embodiments, each longitudinal rib 12 is pivotally provided with a plurality of locking elements, and each mounting groove 13 corresponds to at least three locking elements.

[0033] That is, at least three locking members arranged in a triangular pattern are used to lock the photovoltaic module 2 in the mounting slot 13 to ensure the reliability of locking the photovoltaic module 2 on the upper frame 1. For example, each mounting slot 13 has two locking members on one side and one locking member on the other side along the first direction. This arrangement effectively reduces the number of locking members and thus effectively reduces the installation cost of the photovoltaic module 2 on the upper frame 1.

[0034] Specifically, the locking element can be a strip-shaped structure or a cross-shaped structure. When it is a cross-shaped structure, it can be rotatably installed at the intersection of the longitudinal rib 12 and the transverse rib 11. At this time, one locking element can simultaneously limit the partial positioning of the photovoltaic module 2 in the four mounting slots 13, thereby further reducing the number of locking elements and further reducing the installation cost of the photovoltaic module 2 on the upper frame 1.

[0035] In some embodiments, the main body of the offshore photovoltaic platform 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.

[0036] 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 2 in this part of the mounting slot 13, and the installation efficiency of the photovoltaic module 2 on the upper frame 1 is higher.

[0037] Specifically, for the photovoltaic module 2 which is relatively heavy, tools are usually needed to move the photovoltaic module 2 to complete its fitting in the mounting slot 13. At this time, by setting a pull rod, the locking part can be switched to the avoidance position without the staff having to approach the locking part next to the corresponding mounting slot 13, making the installation of the photovoltaic module 2 convenient and quick.

[0038] In some embodiments, such as Figure 2 As shown, the main body of the offshore photovoltaic platform also includes a first walking pedal 15 extending along a first direction. The first walking pedal 15 and the photovoltaic module 2 are arranged along a second direction. One end of the lever extends to the first walking pedal 15 and is connected to a handle.

[0039] That is, when it is necessary to install the photovoltaic module 2 in the mounting slot 13 which is far away from the first walking pedal 15, the staff only needs to pull the lever at the first walking pedal 15 to switch the locking part corresponding to the mounting slot 13 to the avoidance position. The staff can install the photovoltaic module 2 conveniently and with high safety.

[0040] Specifically, such as Figure 2 As shown, the main body of the offshore photovoltaic platform also includes a second traveling pedal 16 extending along the second direction. The first traveling pedal 15 and the second traveling pedal 16 are intersected and connected. Together, they divide all the photovoltaic modules 2 into multiple areas, which facilitates the maintenance of the photovoltaic modules 2 in each area.

[0041] In some embodiments, the upper frame 1 includes a enclosure 17 surrounding all photovoltaic modules 2, and the main body of the offshore photovoltaic platform also includes a push rod motor, which is mounted on the enclosure 17 and connected to the pull rod drive.

[0042] In other words, when photovoltaic module 2 needs to be installed, the push rod motor can be started. The push rod motor drives the pull rod to move along the length of the longitudinal rib 12 to switch the locking part to the avoidance position. Compared with manually pulling the pull rod, the push rod motor driving method effectively improves the reliability of the locking part's position switching, while also freeing up the workers' hands and further improving the subsequent installation efficiency of photovoltaic module 2.

[0043] Specifically, both ends of the multiple longitudinal beams and multiple transverse beams are welded to the inner edge of the enclosure 17 or to the top of the enclosure 17.

[0044] In some embodiments, such as Figure 3 As shown, the longitudinal rib 12 has a receiving cavity extending in the second direction. The longitudinal rib 12 is provided with a clearance hole 121 that connects the receiving cavity and the mounting groove 13. The locking member in the clearance position is located in the receiving cavity, and the locking member in the locking position protrudes partially from the clearance hole 121 into the mounting groove 13.

[0045] That is, the pull rod and locking component are both hidden in the cavity formed by the longitudinal rib 12, which effectively prevents them from being exposed to the seawater and affecting their service life and locking reliability of the photovoltaic module 2. At the same time, it also effectively prevents the pull rod and locking component from protruding from the upper surface of the photovoltaic module 2, which would affect the appearance of the photovoltaic module 2 and increase the difficulty of cleaning the photovoltaic module 2.

[0046] Specifically, the locking element is a long strip rod. One end of the locking element is pivotally connected to the pull rod, and the middle part of the locking element is pivotally connected to the longitudinal rib 12. When there are mounting grooves 13 on both sides of the pull rod, the locking elements corresponding to the mounting grooves 13 on both sides are pivotally mounted on the pull rod.

[0047] In some embodiments, the transverse rib 11 is provided with a plurality of ventilation holes spaced apart along a first direction.

[0048] The ventilation holes effectively ensure airflow between the upper and lower areas of the upper frame 1, effectively preventing the upper frame 1 and photovoltaic module 2 from being deformed or damaged or detached from the upper frame 1 due to excessive pressure difference from the height direction, thus effectively improving the service life of the photovoltaic module 2.

[0049] In some embodiments, the upper frame 1 further includes a support plate 14 forming the bottom surface of the mounting groove 13. The support plate 14 is provided with a through hole 141 extending in the height direction. A first channel is defined between the support plate 14 and the photovoltaic module 2. A second channel is defined between the outer peripheral surface of the photovoltaic module 2 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 141.

[0050] Therefore, the air below the upper frame 1 can communicate with the air above the upper frame 1 through the through hole 141, the first channel and the second channel, thereby effectively preventing the photovoltaic module 2 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 2.

[0051] Specifically, the upper surface of the tray 14 is provided with a first through groove, which surrounds the lower surface of the photovoltaic module 2 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 2 to form a second channel.
