Description

Technical Field

[0001] The present disclosure relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic module frame and an offshore photovoltaic module. Background Art

[0002] Offshore photovoltaic power generation is a new energy utilization and resource development model. It moves photovoltaic power stations from land to sea. Using photovoltaic technology to build power stations on the ocean, it boasts high power generation capacity, minimal land occupation, and ease of integration with other industries. Compared to onshore photovoltaics, offshore photovoltaics offer natural environmental advantages. Due to the open, unobstructed water surface, the sun shines longer and is fully utilized, significantly increasing power generation.

[0003] In the prior art, a frame is typically installed around the edge of a photovoltaic module. This frame protects the edges of the photovoltaic glass and allows the module to be tied to a floating platform via ropes. The frame is typically a slender, extruded profile. However, the portion of the frame that connects to the photovoltaic module and the portion that connects to the ropes are of different lengths, resulting in material waste. Utility Model Content

[0033] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0034] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of an offshore photovoltaic module when it is floating on the water, and "inner" and "outer" refer to the inner and outer positions relative to the contours of the corresponding component. Terms such as "first" and "second" are used in this disclosure to distinguish one element from another and do not imply order or importance. Furthermore, when the following description refers to the accompanying drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements.

[0035] According to one aspect of the specific embodiment of the present disclosure, a photovoltaic module frame is provided, referring to Figures 1 to 4 As shown, the photovoltaic module frame may include a split protection frame 1 and a mounting frame 2 .

[0036] In the assembled state, both the protective frame 1 and the mounting frame 2 extend along a first direction. The protective frame 1 may be provided with a receiving groove 10 extending along the first direction. The receiving groove 10 is used to receive the edge of a power generation panel (not shown) of an offshore photovoltaic module to protect the panel. The panel may be, for example, a plate-shaped member formed by sealing a solar cell with an encapsulant between front and back glass.

[0037] When the protective frame 1 and the mounting frame 2 are assembled, a mounting frame 2 can be connected to a preset position on each protective frame 1. The length of the mounting frame 2 along the first direction is less than the length of the protective frame 1. A mounting groove 20 extending along the first direction can be provided on a side of the mounting frame 2 facing away from the protective frame 1. The mounting groove 20 is used to install a rope. For example, a member fixed on the rope is embedded in the mounting groove 20. The mounting groove 20 can be a groove with a circular cross-section.

[0038] Through the above technical solution, the photovoltaic module frame provided by the present disclosure is constructed as a split structure, wherein the protective frame 1 is used to accommodate the edge of the power generation panel of the offshore photovoltaic module to protect the power generation panel, and the installation frame 2 is used to install the rope. The installation frame 2 and the protective frame 1 are two independent structures, and the installation frame 2 can be connected to a preset position of the protective frame 1. Through this split design, the protective frame 1 and the installation frame 2 can be processed separately, and the length of the installation frame 2 can be set according to the actual use of the rope and the installation frame 2, thereby avoiding the waste of profiles and saving costs.

[0039] In order to facilitate the assembly of the protective frame 1 and the power generation panel, refer to Figures 1 to 4 As shown, the side of the protective frame 1 facing away from the receiving groove 10 (i.e., the side facing away from the power generation panel) is flat, while the side of the mounting frame 2 facing away from the protective frame 1 is in an outwardly arched shape. For example, the mounting groove 20 is a groove with a circular cross-section, so the wall of the mounting groove 20 is in an arc shape that arches away from the protective frame 1.

[0040] Since the side of the protective frame 1 facing away from the power generation panel is constructed as a plane, it is convenient for the protective frame 1 to cooperate with the robot, so that the robot can evenly push the protective frame 1 under force so that the edge of the power generation panel is embedded in the receiving groove 10, thereby completing the framing. This can not only improve the assembly efficiency, but also avoid the deformation of the photovoltaic module frame caused by uneven force. Afterwards, the installation frame 2 is assembled to the preset position of the protective frame 1.

[0041] In order to facilitate the assembly between the protection frame 1 and the installation frame 2, refer to Figures 1 to 4 As shown, a connecting structure 3 can be provided between the protective frame 1 and the mounting frame 2, so that the mounting frame 2 and the protective frame 1 can slide relative to each other in a first direction and can be locked relative to each other in a second direction perpendicular to the first direction, that is, the mounting frame 2 and the protective frame 1 cannot be separated in the second direction. Through the connecting structure 3, the mounting frame 2 can be connected to the protective frame 1 in a manner extending parallel to the protective frame 1 and can slide in the first direction to a preset position.

[0042] The mounting frame 2 can also be positioned at a preset position on the protective frame 1. Alternatively, the protective frame 1 and the mounting frame 2 can be riveted together at the preset position. Alternatively, a limiting member can be provided at the preset position of the protective frame 1. The limiting member can be configured so that when the mounting frame 2 is at the preset position, the limiting member can be located at both ends of the mounting frame 2, thereby retaining the mounting frame 2 in the preset position through the stopper provided by the limiting member. The limiting member can be a stop block, a snap, or other structure.

[0043] During the actual assembly process, the installation frame 2 can also be connected to the protective frame 1 through the connecting structure 3 first, and the installation frame 2 can be slid to the preset position on the protective frame 1. Then, the installation frame 2 needs to be restricted from sliding in the length direction of the protective frame 1 so that the installation frame 2 remains in the preset position. For example, the installation frame 2 can be fixed at the preset position by rivets, or the installation frame 2 can be limited at the preset position by a cable tie and / or a stop block or clip set at the preset position. Finally, the protective frame 1 is assembled with the power generation panel.

[0044] The protective frame 1 can be substantially the same length as the length of the power generation panel. Depending on the actual situation, the mounting frame 2 can be longer, that is, a mounting frame 2 of a longer length can be connected to one protective frame 1. For example, the mounting frame 2 can be 800-1000 mm. In addition, the mounting frame 2 can also be segmented, that is, a plurality of shorter mounting frames 2 are connected to one protective frame 1, and these mounting frames 2 are spaced apart on the same protective frame 1. It should be noted that the present disclosure does not specifically limit the number of mounting frames 2 connected to one protective frame 1 and the length of each mounting frame 2.

[0045] In order to enable the installation frame 2 and the protection frame 1 to slide relative to each other along the first direction and to be locked relative to each other along the second direction, as a specific embodiment of the present disclosure, reference is made to Figures 1 to 4 As shown, the connecting structure 3 may include a slider 31 and a slide groove 32 that can be fitted into each other, that is, the outer contour of the cross section of the slider 31 along the second direction (hereinafter referred to as the cross section of the slider 31) and the inner contour of the cross section of the slide groove 32 along the second direction (hereinafter referred to as the cross section of the slide groove 32) can match each other, the slide groove 32 can extend along the first direction, one of the slider 31 and the slide groove 32 can be placed in the protective frame 1, and the other of the slider 31 and the slide groove 32 can be set in the installation frame 2.

[0046] As an alternative, refer to Figures 1 to 4 As shown, the slider 31 is provided on the installation frame 2, and the slide groove 32 is provided on the protection frame 1. As another option not shown, the slider 31 can be provided on the installation frame 2, and the slide groove 32 can be provided on the protection frame 1.

[0047] As an embodiment of the slider 31 and the chute 32, refer to Figure 3 and Figure 4 As shown, the cross-sections of the slide groove 32 and the slider 31 can both be T-shaped, so that the slider 31 can slide in the slide groove 32 along the first direction without falling out of the slide groove 32 along the second direction, thereby allowing the mounting frame 2 and the protective frame 1 to slide relative to each other along the first direction and be locked relative to each other along the second direction.

[0048] As another unillustrated embodiment of the slider 31 and the slot 32, the cross-sections of the slot 32 and the slider 31 can both be dovetail-shaped, so that the slider 31 can slide in the slot 32 along the first direction without falling out of the slot 32 along the second direction, thereby allowing the mounting frame 2 and the protective frame 1 to slide relative to each other along the first direction and be locked relative to each other along the second direction.

[0049] As another embodiment of the slider 31 and the chute 32, refer to Figure 1 and Figure 2 As shown, the cross-sections of the slide groove 32 and the slider 31 can both be L-shaped, so that the slider 31 can slide in the slide groove 32 along the first direction without falling out of the slide groove 32 along the second direction, thereby allowing the mounting frame 2 and the protective frame 1 to slide relative to each other along the first direction and be locked relative to each other along the second direction.

[0050] It should be noted that in the specific embodiment of the present disclosure, there is no specific restriction on the cross-sectional shapes of the slider 31 and the slide groove 32, as long as the slider 31 can slide in the slide groove 32 along the first direction without falling out of the slide groove 32 along the second direction.

[0051] In order to improve the connection reliability between the installation frame 2 and the protection frame 1, refer to Figure 3 As shown, the connection structure 3 may include multiple groups of sliders 31 and sliding grooves 32 .

[0052] As an option, multiple groups of sliders 31 and slide grooves 32 can have the same structure, for example, Figure 3 The cross sections of the two groups of sliders 31 and the sliding grooves 32 shown in FIG are both T-shaped.

[0053] As another option, multiple groups of sliders 31 and slide grooves 32 can also have different structures. Taking the connecting structure 3 including two groups of sliders 31 and slide grooves 32 as an example, the cross-section of one group of sliders 31 and slide grooves 32 can be T-shaped, and the cross-section of the other group of sliders 31 and slide grooves 32 can be a cross-section.

[0054] As an option, all sliders 31 can be set on the protection frame 1, and all slide grooves 32 can be set on the installation frame 2, or all sliders 31 can be set on the installation frame 2, and all slide grooves 32 can be set on the protection frame 1.

[0055] As another option, a portion of the multiple sliders 31 can be set on the protective frame 1, and accordingly, the sliding grooves 32 that cooperate with these sliders 31 can be set on the mounting frame 2; another portion of the multiple sliders 31 can be set on the mounting frame 2, and the sliding grooves 32 that cooperate with these sliders 31 can be set on the protective frame 1.

[0056] In order to enable the mounting frame 2 and the protective frame 1 to slide relative to each other in the first direction and be locked relative to each other in the second direction, as another specific embodiment of the present disclosure, the connecting structure 3 may also include a first groove 33 and a second groove 34, wherein the first groove 33 can be arranged on the protective frame 1 and extend along the first direction, and the second groove 34 can be arranged on the mounting frame 2 and extend along the first direction; wherein, one side wall of the first groove 33 is accommodated in the second groove 34, and one side wall of the second groove 34 is accommodated in the first groove 33, so that the first groove 33 and the second groove 34 are locked to each other along the second direction.

[0057] In order to improve the connection reliability between the installation frame 2 and the protection frame 1 , the connection structure 3 may include multiple groups of first grooves 33 and second grooves 34 .

[0058] In addition, reference Figure 1 and Figure 4 As shown, the connection structure 3 may also include a group of sliders 31 and sliding grooves 32 , and a group of first grooves 33 and second grooves 34 .

[0059] In order to facilitate the assembly between the installation frame 2 and the protection frame 1, refer to Figures 1 to 4 As shown, the opening directions of the receiving groove 10 and the installation groove 20 are both away from the connection structure 3 to prevent the power generation panel in the receiving groove 10 and / or the rope in the installation groove 20 from interfering with the assembly between the installation frame 2 and the protection frame 1.

[0060] According to another aspect of the specific embodiment of the present disclosure, a photovoltaic assembly frame is provided, referring to Figures 1 to 4 As shown, the photovoltaic module frame may include a split protection frame 1 and a mounting frame 2 .

[0061] In the assembled state, both the protective frame 1 and the mounting frame 2 extend along a first direction. The protective frame 1 may be provided with a receiving groove 10 extending along the first direction. The receiving groove 10 is used to receive the edge of a power generation panel (not shown) of an offshore photovoltaic module to protect the panel. The panel may be, for example, a plate-shaped member formed by sealing a solar cell with an encapsulant between front and back glass.

[0062] When the protective frame 1 and the mounting frame 2 are assembled, each preset position on the protective frame 1 can be connected to a mounting frame 2. A mounting groove 20 extending along a first direction can be provided on a side of the mounting frame 2 facing away from the protective frame 1. The mounting groove 20 is used to mount a rope, for example, a member fixed to the rope is embedded in the mounting groove 20. The mounting groove 20 can be a groove with a circular cross-section.

[0063] In order to facilitate the assembly of the protective frame 1 and the power generation panel, refer to Figures 1 to 4As shown, the side of the protective frame 1 facing away from the receiving groove 10 (i.e., the side facing away from the power generation panel) can be flat, and the side of the mounting frame 2 facing away from the protective frame 1 can be an outwardly arched arc. For example, the mounting groove 20 is a groove with a circular cross-section, so the wall of the mounting groove 20 is an arc that arches away from the protective frame 1.

[0064] Through the above technical solution, since the side of the protective frame 1 facing away from the power generation panel is constructed as a plane, it is convenient for the protective frame 1 to cooperate with the robot, so that the robot can evenly push the protective frame 1 under force to embed the edge of the power generation panel into the receiving groove 10, thereby completing the framing. This can not only improve the assembly efficiency, but also avoid the deformation of the photovoltaic module frame caused by uneven force. Afterwards, the installation frame 2 is assembled to the preset position of the protective frame 1.

[0065] Based on the above technical solutions, the present disclosure further provides an offshore photovoltaic module comprising at least one pair of photovoltaic module frames according to the above technical solutions. The offshore photovoltaic module may further include a rectangular power generation panel, which may include a laminated front glass, a solar cell array, and a back glass. An encapsulant may be provided between the front glass and the back glass to seal the solar cells. At least one pair of opposite sides of the rectangular power generation panel are provided with any of the photovoltaic module frames according to the above technical solutions.

[0066] Through the above technical solution, the offshore photovoltaic module provided by the present disclosure has the same technical effect as the photovoltaic module frame in the above technical solution. In order to avoid unnecessary repetition, it will not be described here.

[0067] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0069] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
