Description

Technical Field

[0001] This application relates to the field of photovoltaic system technology, and in particular to photovoltaic systems and their briquetting devices. Background Technology

[0002] Photovoltaic modules are typically fixed to purlins using clamps. Each clamp has two sidewalls. During installation, the two sidewalls of the clamp are connected to the frames of two adjacent photovoltaic modules, and then bolts are passed through the clamp and purlin in sequence to lock the clamp onto the purlin, thus securing the photovoltaic modules.

[0003] However, when the photovoltaic module is subjected to a downward load, the frame can easily cause the two side walls of the pressure block to bend to the side that is far apart from each other, which can cause the pressure block to come off the frame of the photovoltaic module. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic system and its pressing device to address the problem that when photovoltaic modules are subjected to compressive loads, the frame and the two side walls of the pressing block tend to bend to the side that are far apart from each other.

[0005] A briquetting device, the briquetting device comprising:

[0006] The first pressing block includes a first base and snap-fit ​​arms respectively disposed on both sides of the first base along a first direction. Each snap-fit ​​arm is provided with a first snap-fit ​​structure and a second snap-fit ​​structure arranged sequentially along a second direction. The first snap-fit ​​structure is used to snap-fit ​​with the frame of the photovoltaic module.

[0007] The second pressure block is disposed between the two locking arms. The second pressure block has a third locking structure, which is locked in one-to-one with the second locking structure.

[0008] The locking element passes sequentially through the second pressure block, the first pressure block, and the support member on the building to secure the three together.

[0009] In one embodiment, the second pressure block includes a second base, and the second base is provided with third snap-fit ​​structures at both ends along a first direction. The second base is disposed on the first base, and the locking member is used to pass through the second base, the first base, and the support member in sequence.

[0010] In one embodiment, two second snap-fit ​​structures extend toward each other on one side, and the third snap-fit ​​structure hooks onto the corresponding second snap-fit ​​structure.

[0011] In one embodiment, the snap-fit ​​arm and / or the first snap-fit ​​structure are capable of elastic deformation.

[0012] In one embodiment, the two first snap-fit ​​structures extend toward each other on one side, the first snap-fit ​​structure being located on the side of the second snap-fit ​​structure away from the first base, and the side of the first snap-fit ​​structure away from the second snap-fit ​​structure being provided with a hook for engaging with a snap-fit ​​portion on the frame.

[0013] In one embodiment, along the second direction, the first snap-fit ​​structure gradually tilts away from the snap-fit ​​arm towards the side away from the second snap-fit ​​structure.

[0014] In one embodiment, a support portion is provided on the side of the first base away from the second base, the support portion being used to create gaps between the first base and the support member on both sides along a first direction.

[0015] In one embodiment, the first base has a ramp on the side away from the second base, and along the direction from the middle to both sides in a first direction of the first base, the ramp gradually slopes away from the support member, and the two sides of the first base along the first direction are respectively used to slide into the frame through the ramp.

[0016] In one embodiment, the first base and / or the second base includes a first bottom wall and a second bottom wall spaced apart along a second direction, the first bottom wall and the second bottom wall being connected to each other at their ends along a first direction.

[0017] A photovoltaic system includes a support, photovoltaic modules, and a pressing device. The photovoltaic modules have frames, and the pressing device simultaneously presses the frames of two adjacent photovoltaic modules onto the support. The frames are provided with snap-fit ​​parts, and the snap-fit ​​parts of two adjacent frames respectively snap-fit ​​with corresponding snap-fit ​​arms. A locking member is used to simultaneously fix a first pressing block and a second pressing block to the support.

[0018] In the aforementioned photovoltaic system and its clamping device, the two locking arms of the first clamping block are respectively used to clamp onto the frame of the photovoltaic module through the first locking structure, thereby connecting the first clamping block to the frame and facilitating the fixing of the photovoltaic module to the support member. Simultaneously, the third locking structure corresponds one-to-one with the second locking structure, that is, the second clamping block increases the strength of the locking arms, preventing the two locking arms from bending to opposite sides when the photovoltaic module is subjected to external loads, thus preventing the clamping block from detaching from the photovoltaic module. Furthermore, the first and second clamping blocks are set separately. The locking arms of the first clamping block clamp onto the frame of the photovoltaic module. Due to the limited strength of a single first clamping block, it is easy to embed into the frame, making installation more labor-saving. Attached Figure Description

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0029] Combination Figure 1 To facilitate understanding of this case, let's first introduce the photovoltaic module. The photovoltaic module includes a laminate and a frame surrounding the laminate. Two adjacent photovoltaic modules are designated as a first photovoltaic module and a second photovoltaic module. The frame 400 includes a first sidewall 430, a second sidewall 440, and a third sidewall 450 connected sequentially to form a mounting groove 460. A snap-fit ​​portion 431 is provided on the inner side of the first sidewall 430, and a mating surface 451 is provided on the inner side of the third sidewall 450. A pressing device is embedded into the corresponding mounting groove 460 on the frame 400 on both sides along a first direction.

[0030] See Figures 1-3An embodiment of this application provides a pressing device, which includes a first pressing block 100, a second pressing block 200, and a locking member 300. The first pressing block 100 includes a first base 110 and snap-fit ​​arms 120 respectively disposed on both sides of the first base 110 along a first direction. Each snap-fit ​​arm 120 is provided with a first snap-fit ​​structure 130 and a second snap-fit ​​structure 140 arranged sequentially along a second direction. The first snap-fit ​​structure 130 is used to snap-fit ​​with the snap-fit ​​portion 431 on the frame 400 of the photovoltaic module. The second pressing block 200 is disposed between the two snap-fit ​​arms 120. The second pressing block 200 has a third snap-fit ​​structure 220, which snaps into the second snap-fit ​​structure 140 in a one-to-one correspondence. The locking member 300 passes through the second pressing block 200, the first pressing block 100, and the support member 500 on the building in sequence to fix the three together.

[0031] In this embodiment, the two snap-fit ​​arms 120 of the first pressure block 100 are respectively used to snap onto the frame 400 of the photovoltaic module through the first snap-fit ​​structure 130, thereby connecting the first pressure block 100 to the frame 400 and facilitating the fixing of the photovoltaic module onto the support member 500 through the first pressure block 100. Simultaneously, the third snap-fit ​​structure 220 is connected one-to-one with the second snap-fit ​​structure 140, that is, the second pressure block 200 increases the strength of the snap-fit ​​arms 120, preventing the two snap-fit ​​arms 120 from bending to opposite sides when the photovoltaic module is subjected to external loads, thus preventing the pressure block from detaching from the photovoltaic module. Furthermore, the first pressure block 100 and the second pressure block 200 are separately arranged. The snap-fit ​​arms 120 of the first pressure block 100 snap onto the frame 400 of the photovoltaic module. Since the strength of a single first pressure block 100 is limited, it is easy to embed into the frame 400, making installation more labor-saving.

[0032] In some embodiments, the second pressing block 200 includes a second base 210, and the second base 210 is provided with a third snap-fit ​​structure 220 at both ends along the first direction. The second base 210 is disposed on the first base 110, and the locking member 300 is used to pass through the second base 210, the first base 110 and the support member 500 in sequence.

[0033] In this embodiment, the second base 210 is disposed on the first base 110, so that the locking member 300 passes through the second base 210, the first base 110 and the support member 500 in sequence, so as to fix the second pressing block 200 and the first pressing block 100 on the support member 500 at the same time.

[0034] In other embodiments, the ends of the two third snap-fit ​​structures furthest from the second snap-fit ​​portion can be connected to each other. In this case, the second pressure block and the first pressure block are spaced apart, and the second pressure block is located inside the two snap-fit ​​arms, with both ends snapped into the second snap-fit ​​portion, to prevent the two snap-fit ​​arms from bending to the side furthest from each other.

[0035] In some embodiments, two second snap-fit ​​structures 140 extend toward each other, and a third snap-fit ​​structure 220 hooks onto the corresponding second snap-fit ​​structure 140.

[0036] With this configuration, the third snap-fit ​​structure 220 and the second snap-fit ​​structure 140 are connected by a hook, facilitating the quick connection of the second pressure block 200 and the first pressure block 100. Specifically, the third snap-fit ​​structure 220 and the second snap-fit ​​structure 140 are hooked together by a U-shaped structure.

[0037] In some embodiments, the snap-fit ​​arm 120 and / or the first snap-fit ​​structure 130 can undergo elastic deformation.

[0038] Specifically, the snap-fit ​​arm 120 can undergo elastic deformation; or the first snap-fit ​​structure 130 can undergo elastic deformation; or both the snap-fit ​​arm 120 and the first snap-fit ​​structure 130 can undergo elastic deformation.

[0039] This application thins the snap-fit ​​arm 120 and the first snap-fit ​​structure 130, enabling both the snap-fit ​​arm 120 and the first snap-fit ​​structure 130 to undergo elastic deformation. During photovoltaic system installation, the first photovoltaic module is first installed; then the first snap-fit ​​structure 130 is snapped into the frame 400 of the first photovoltaic module; next, the locking device is locked onto the support member 500 by the locking member 300; finally, the second photovoltaic module is pushed towards the side closest to the locking device along the first direction, causing the second photovoltaic module to compress the other snap-fit ​​arm 120 and the first snap-fit ​​structure 130, resulting in elastic deformation, and thus the other first snap-fit ​​structure 130 snaps into the frame 400 of the second photovoltaic module. Because the snap-fit ​​arm 120 and the first snap-fit ​​structure 130 can undergo elastic deformation, the locking device can be directly locked by the locking member 300 during photovoltaic module installation, eliminating the need for repeated adjustments to the locking member 300, resulting in high installation efficiency.

[0040] In some embodiments, two first snap-fit ​​structures 130 extend toward each other, the first snap-fit ​​structure 130 is located on the side of the second snap-fit ​​structure 140 away from the first base 110, and a hook portion 141 is provided on the side of the first snap-fit ​​structure 130 away from the second snap-fit ​​structure 140, the hook portion 141 being used to hook with the snap-fit ​​portion 431 on the frame 400.

[0041] In this embodiment, the first snap-fit ​​structure 130 is located on the side of the second snap-fit ​​structure 140 away from the first base 110, and the side of the first snap-fit ​​structure 130 away from the second snap-fit ​​structure 140 is provided with a hook portion 141. That is, when the snap-fit ​​arm 120 is embedded into the frame 400 of the photovoltaic module, it is convenient for the snap-fit ​​portion 431 on the inner side of the first sidewall 430 to hook with the hook portion 141.

[0042] In some embodiments, along a second direction, the first snap-fit ​​structure 130 gradually tilts away from the snap-fit ​​arm 120 toward the side away from the second snap-fit ​​structure 140. The second direction is a vertical direction.

[0043] In this embodiment, when installing the pressure block, since the first snap-fit ​​structure 130 is tilted away from the snap-fit ​​arm 120 to the side away from the second snap-fit ​​structure 140, the snap-fit ​​portion 431 on the frame 400 can gradually push the first snap-fit ​​structure 130 or the snap-fit ​​arm 120 to deform, thereby reducing the thrust and making installation easier.

[0044] In some embodiments, the first base 110 and / or the second base 210 include a first bottom wall 211 and a second bottom wall 212 spaced apart along a second direction.

[0045] In this embodiment, the second base 210 is described as including a first bottom wall 211 and a second bottom wall 212 spaced apart along a second direction. The first bottom wall 211 and the second bottom wall 212 are connected to each other at both ends along the first direction. The first bottom wall 211 and the second bottom are provided to ensure the support strength of the second base 210. The first bottom wall 211 and the second bottom wall 212 are spaced apart to reduce their own weight.

[0046] The first bottom wall 211 is located on the side of the second bottom wall 212 away from the first base 110, and the first bottom wall 211 is provided with a third snap-fit ​​structure 220 on both sides along the first direction.

[0047] In other embodiments, the first base 110 may include a first bottom wall 211 and a second bottom wall 212 spaced apart along the second direction, or the first base 110 and the second base 210 may each include a first bottom wall 211 and a second bottom wall 212 spaced apart along the second direction.

[0048] In some embodiments, a support portion 113 is provided on the side of the first base 110 away from the second base 210, and the support portion 113 is used to create a gap between the first base 110 and the support member 500 on both sides along the first direction.

[0049] In this embodiment, the bottom of the first base 110 is provided with two support portions 113, and there is a preset distance between the support portions 113 and the two ends of the first base 110 along the first direction. The two support portions 113 are used to support the first base 110, so that when the first base 110 is placed on the support member 500, there is a gap between the two ends of the first base 110 along the first direction and the support member 500, so that the third sidewall 450 of the frame 400 can extend into the gap, thereby pressing the frame 400 onto the support member 500 by the first pressing block 100. The preset distance is greater than or equal to the length of the third sidewall 450 of the frame 400.

[0050] Furthermore, the two support parts 113 have different dimensions along the second direction to support two different gaps. During installation, the side of the first pressure block 100 with the smaller gap is first embedded into the frame 400 of the first photovoltaic module, and then the pressure block device is fixed. Finally, the second photovoltaic module is pushed along the first direction towards the side closer to the pressure block device. At this time, since the gap on the side closer to the second photovoltaic module is larger, it is easy for the pressure block device to be easily embedded into the frame 400 of the second photovoltaic module.

[0051] In some embodiments, the first base 110 has a slope 114 on the side away from the second base 210, and the slope 114 gradually slopes away from the support 500 along the direction from the middle to both sides in the first direction of the first base. The two sides of the first base along the first direction are respectively used to slide into the frame 400 through the slope 114.

[0052] With this configuration, the inclined surface 114 gradually slopes towards the second base 210 along the direction from the center to both sides in the first direction of the base. Correspondingly, a mating surface 451 is provided on the third sidewall 450 of the frame 400. The inclination angle of the mating surface 451 is the same as that of the inclined surface 114, so that when the first pressing block 100 is embedded into the mounting groove 460, the inclined surface 114 and the third sidewall 450 fit together. By setting the inclined surface 114, the pushing force can be reduced when the first base 110 is pushed into the frame 400 in the first direction.

[0053] An embodiment of this application also provides a photovoltaic system, which includes a support member 500, a photovoltaic module, and a pressing device. The photovoltaic module has a frame 400. The pressing device simultaneously presses the frames 400 of two adjacent photovoltaic modules onto the support member 500. The frame 400 is provided with a snap-fit ​​part 431. The snap-fit ​​parts 431 of two adjacent frames 400 respectively snap-fit ​​with the corresponding snap-fit ​​arms 120. The locking member 300 is used to simultaneously fix the first pressing block 100 and the second pressing block 200 to the support member 500.

[0054] In this embodiment, the strength of the snap-fit ​​arm 120 is increased by the second pressure block 200, which prevents the two snap-fit ​​arms 120 from bending to the opposite side when the photovoltaic module is subjected to external load, thereby causing the pressure block to come out of the photovoltaic module and thus enhancing the support strength of the entire photovoltaic system.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
