[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] Combine the following Figure 1-Figure 3 An offshore photovoltaic platform body according to an embodiment of the present invention is described.

[0025] The main body of the offshore photovoltaic platform of the embodiment of the present invention includes an upper frame 1, a locking member and an elastic member. A plurality of mounting grooves 13 are provided on the upper surface of the upper frame 1, and the mounting grooves 13 correspond to the photovoltaic modules 2 one by one, and the mounting grooves 13 are provided for the corresponding photovoltaic modules 2 to cooperate. The locking member is pivotally connected to the upper frame 1, and the locking member has an avoidance position located beside the mounting groove 13 and a locking position located inside or above the mounting groove 13. The locking member located at the locking position is suitable for pressing the frame of the photovoltaic module 2. The elastic member connects the locking member and the upper frame 1, and the elastic member presses the locking member toward the locking position.

[0026] According to the offshore photovoltaic platform of the embodiment of the present invention, the upper surface of the upper frame 1 is provided with mounting grooves 13 equal to the number of photovoltaic modules 2, the locking member is pivotally connected to the upper frame 1, and under the pressure of the elastic member, the locking member has a locking position partially located above or inside the mounting groove 13. Therefore, when the photovoltaic module 2 needs to be installed, the locking member is controlled to move to the avoidance position of avoiding the mounting groove 13, and then the photovoltaic module 2 is placed in the mounting groove 13, and then 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 2, or partially located in the mounting groove 13 and pressed against the outer peripheral surface of the frame of the photovoltaic module 2, thereby realizing the locking of the photovoltaic module 2, wherein the entire installation process is completed above the upper frame 1, and the installation efficiency of the photovoltaic module 2 on the upper frame 1 is high.

[0027] It should be noted that when the locking position of the locking member is partially located in the installation groove 13, it is preferred to set a limit groove on the outer peripheral surface of the frame of the photovoltaic module 2, and the locking member is partially inserted into the limit groove when it is in the locking position, 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, and 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 lower end of the column 3 are provided with a float 5. The main body of the offshore photovoltaic platform floats on the sea surface through the float 5, and the upper frame 1 and the photovoltaic module 2 are higher than the sea surface by a certain height.

[0028] In some embodiments, Figure 2 As shown, the upper frame 1 includes a plurality of longitudinal ribs 12 arranged at intervals along a first direction and a plurality of transverse ribs 11 arranged at intervals 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 cross-arranged and surround the sides forming a plurality of mounting grooves 13. The locking member is pivotally connected to the longitudinal ribs 12.

[0029] A plurality of transverse ribs 11 and a plurality of longitudinal ribs 12 are cross-welded to each other, thereby forming a plurality of side surfaces of rectangular mounting grooves 13 of substantially the same size. At this time, by pivotally mounting the locking members on the longitudinal ribs 12, there is no need to design the transverse ribs 11 for mounting the locking members. The structure of the transverse ribs 11 is simpler and the manufacturing cost of the upper frame 1 is lower.

[0030] Specifically, a plurality of longitudinal ribs 12 are arranged at equal intervals in the first direction, and a plurality of transverse ribs 11 are arranged at equal intervals in the second direction. The photovoltaic component 2 arranged in the installation groove 13 is locked and limited only by locking members on two opposite sides in the first direction to complete the reliable installation of the photovoltaic component 2 on the upper frame 1.

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

[0032] In some embodiments, a plurality of locking members are pivotably provided on each longitudinal rib 12 , and each mounting slot 13 corresponds to at least three locking members.

[0033] That is, at least three locking members arranged in a triangle are used to lock the photovoltaic module 2 in the installation groove 13, so as to ensure the reliability of the locking of the photovoltaic module 2 on the upper frame 1. For example, two locking members are correspondingly arranged on one side of each installation groove 13 along the first direction, and one locking member is correspondingly arranged on the other side. This arrangement effectively reduces the number of locking members arranged, thereby effectively reducing the installation cost of the photovoltaic module 2 on the upper frame 1.

[0034] Specifically, the locking member can be a strip rod structure or a cross rod structure. When it is a cross rod structure, it can be rotatably installed at the intersection of the longitudinal rib 12 and the transverse rib 11. At this time, one locking member can simultaneously realize partial positioning of the photovoltaic components 2 in the four installation grooves 13, thereby further reducing the number of locking members arranged, so as to further reduce the installation cost of the photovoltaic components 2 on the upper frame 1.

[0035] In some embodiments, the offshore photovoltaic platform body also includes a tie rod, which corresponds to the longitudinal reinforcement 12 one by one, and is slidably connected to the longitudinal reinforcement 12 along the second direction. The tie rod is also pivotally connected to all locking members on the corresponding longitudinal reinforcement 12.

[0036] Therefore, by pulling two adjacent pull rods to move along the extension direction of the longitudinal reinforcement 12, the locking members corresponding to all the installation grooves 13 located between the two pull rods can be switched to the avoidance position, thereby facilitating the installation of the photovoltaic components 2 in the installation grooves 13, and the installation efficiency of the photovoltaic components 2 on the upper frame 1 is higher.

[0037] Specifically, for photovoltaic components 2 with heavier weight, tools are usually required to move the photovoltaic components 2 to complete their fit in the installation groove 13. At this time, by setting a pull rod, the locking member can be switched to the avoidance position without the staff approaching the locking member next to the corresponding installation groove 13, and the installation of the photovoltaic component 2 is convenient and quick.

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

[0039] That is, when the photovoltaic component 2 needs to be installed in the installation groove 13 far away from the first walking pedal 15, the staff only needs to pull the pull rod at the first walking pedal 15 to switch the locking part corresponding to the installation groove 13 to the avoidance position, which makes it convenient for the staff to install the photovoltaic component 2 with high safety.

[0040] Specifically, Figure 2 As shown, the main body of the offshore photovoltaic platform also includes a second walking pedal 16 extending along the second direction. The first walking pedal 15 and the second walking pedal 16 are cross-connected. The two together separate all photovoltaic components 2 into multiple areas, thereby facilitating the maintenance of the photovoltaic components 2 in each area.

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

[0042] That is, when the photovoltaic component 2 needs to be installed, the push rod motor can be started, and the push rod motor drives the pull rod to move along the length direction of the longitudinal reinforcement 12 to switch the locking piece to the avoidance position. Compared with manually pulling the pull rod, the push rod motor drive method effectively improves the reliability of the position switching of the locking piece, while also freeing the hands of the staff, further improving the subsequent installation efficiency of the photovoltaic component 2.

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

[0044] In some embodiments, Figure 3 As shown, the longitudinal rib 12 has a accommodating cavity extending along the second direction, and the longitudinal rib 12 is provided with an avoidance hole 121 connecting the accommodating cavity and the mounting groove 13. The locking member located at the avoidance position is located in the accommodating cavity, and the locking member located at the locking position protrudes out of the mounting groove 13 through the avoidance hole 121.

[0045] That is, the pull rod and the locking piece are hidden in the accommodating cavity formed by the longitudinal rib 12, which effectively prevents them from being exposed to the sea water and affecting their service life and the locking reliability of the photovoltaic module 2. It also effectively prevents the pull rod and the locking piece from protruding from the upper surface of the photovoltaic module 2 and affecting the appearance of the photovoltaic module 2 and increasing the difficulty of cleaning the photovoltaic module 2.

[0046] Specifically, the locking member is a long strip rod, one end of which is pivotally connected to the pull rod, and the middle part of the locking member is pivotally connected to the longitudinal rib 12. In the case where installation grooves 13 are provided on both sides of the pull rod, the parts of the locking members corresponding to the installation 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 arranged at intervals along the first direction.

[0048] The setting of the ventilation holes effectively ensures the connectivity of air between the upper and lower areas of the upper frame 1, effectively preventing the upper frame 1 and the photovoltaic module 2 from being subjected to excessive pressure difference in the height direction, which may cause the upper frame 1 and the photovoltaic module 2 to be deformed, damaged or detached from the upper frame 1, thereby effectively improving the service life of the photovoltaic module 2.

[0049] In some embodiments, the upper frame 1 also includes a support plate 14 that constitutes the bottom surface of the mounting groove 13, and the support plate 14 is provided with a through hole 141 extending along the height direction. A first channel is defined between the support plate 14 and the photovoltaic component 2, and a second channel extending along the height direction to the upper surface of the upper frame 1 is defined between the outer peripheral surface of the photovoltaic component 2 and the side surface of the mounting groove 13, and the first channel connects the second channel and the through hole 141.

[0050] Therefore, the air below the upper frame 1 can be connected to the air above the upper frame 1 through the through hole 141, the first channel and the second channel, thereby effectively preventing the photovoltaic component 2 from loosening or even detaching from the upper frame 1 due to excessive pressure difference from the height direction, thereby effectively improving the service life of the photovoltaic component 2.

[0051] Specifically, a first through groove is provided on the upper surface of the support plate 14, and the first through groove and the lower surface of the photovoltaic component 2 form a first channel. A second through groove extending along the height direction is provided on the side of the installation groove 13, and the second channel and the peripheral surface of the photovoltaic component 2 form a second channel.
