TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic systems, in particular to a photovoltaic system and a pressing block device thereof. BACKGROUND

[0002] A photovoltaic module is generally fixed on a purlin by a pressing block. During installation, the two ends of the pressing block are connected with the frames of two adjacent photovoltaic modules and are limited by each other, and then a bolt is sequentially threaded through the pressing block and the purlin to lock the pressing block on the purlin, thereby fixing the photovoltaic module.

[0003] However, when the photovoltaic module is disassembled, the pressing block is difficult to separate from the frame of the photovoltaic module due to the limiting cooperation of the frame and the pressing block. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a photovoltaic system and a pressing block device thereof to solve the problem that the pressing block is difficult to separate from the frame of the photovoltaic module when the photovoltaic module is disassembled.

[0005] A pressing block device, comprising:

[0006] two pressing blocks, each of which comprises a base body and a clamping arm arranged on the base body, the two base bodies are arranged in sequence along a first direction, the two clamping arms extend towards one side close to each other, and the two clamping arms are respectively clamped with the frames of two adjacent photovoltaic modules one by one;

[0007] a locking member for threading along a second direction between the two clamping arms to fix the two pressing blocks on a support member of a building;

[0008] wherein the clamping arm can be elastically deformed, and the clamping arm is configured to separate from the corresponding frame when being pressed.

[0009] In one of the embodiments, the two clamping arms have overlapping portions along the first direction, and the locking member is used to thread along the second direction between the overlapping portions of the two clamping arms.

[0010] In one of the embodiments, the base body comprises a base and a side wall arranged at one end of the base along the first direction, the clamping arm is arranged at the side of the side wall away from the base, the base and the clamping arm of the same pressing block are oppositely arranged, the two bases have overlapping portions extending along the first direction, and the locking member is threaded between the overlapping portions of the two clamping arms and the overlapping portions of the two bases in sequence.

[0011] In one of the embodiments, along the direction from the base to the clamping arm, the thickness of the side wall along the first direction decreases in sequence.

[0012] In one embodiment, the pressing device includes a support block for being disposed between the snap-fit ​​arm and the base along a second direction, and the locking member is sequentially disposed through the snap-fit ​​arm, the support block and the base along the second direction.

[0013] In one embodiment, the two pressure blocks include a first pressure block and a second pressure block, wherein the locking arm and base of the first pressure block are simultaneously sleeved on the locking arm and base of the second pressure block, and the locking member is sequentially inserted along a second direction through the locking arm of the first pressure block, the locking arm of the second pressure block, the support block, the base of the second pressure block, and the base of the first pressure block.

[0014] In one embodiment, a first recess is provided on the base of the first pressing block, and a first protrusion is provided on the base of the second pressing block, wherein the first recess engages with the first protrusion.

[0015] And / or, the first pressure block has a second recess on its locking arm and a second protrusion on its locking arm, the second recess engaging with the second protrusion.

[0016] In one embodiment, the snap-fit ​​arm is provided with a snap hook for engaging with a snap-fit ​​portion on the frame.

[0017] In one embodiment, the snap-fit ​​arm includes a snap-fit ​​section and a crimping section connected in sequence. When the snap-fit ​​arm rotates at a first angle, the snap-fit ​​section tilts from the side wall toward the side away from the base. The snap hook is disposed at one end of the snap-fit ​​section near the crimping section, and the locking member passes through the crimping section.

[0030] Combination Figure 1To facilitate understanding of this case, let's first introduce the photovoltaic module. The photovoltaic module includes a laminate and a frame 400 surrounding the laminate. Two adjacent photovoltaic modules are designated as a first photovoltaic module and a second photovoltaic module, and these modules are arranged along a first direction. 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 each side of the frame 400 along the first direction OX.

[0031] See Figures 1-3 An embodiment of this application provides a pressing device, which includes two pressing blocks 100 and a locking member 300. Each pressing block 100 includes a base 130 and a snap-fit ​​arm 140 disposed on the base 130. The two bases 130 are arranged sequentially along a first direction. The two snap-fit ​​arms 140 extend toward each other and are snapped into the frames 400 of two adjacent photovoltaic modules respectively. The locking member 300 passes through the two snap-fit ​​arms 140 along a second direction to fix the two pressing blocks 100 to the support member 500 on the building. The snap-fit ​​arms 140 are capable of elastic deformation and are configured to disengage from the corresponding frame 400 when pressed.

[0032] Specifically, the snap-fit ​​arm 140 has a first rotation angle and a second rotation angle that are rotatably connected to the base 130; at the first rotation angle, it is combined with... Figure 2 The snap-fit ​​arm 140 snaps into the corresponding frame 400; at the second rotation angle, it engages with... Figure 2 The latching arm 140 disengages from the corresponding frame 400; pressing the latching arm 140 allows it to rotate from a first rotation angle to a second rotation angle, and the locking member 300 is used to lock the latching arm 140 at the first rotation angle.

[0033] In this embodiment, two clamping blocks 100 are respectively clamped to two adjacent photovoltaic modules via two clamping arms 140. Simultaneously, the clamping arms 140 are connected to a support member 500 on the building via a locking member 300, thereby fixing the photovoltaic modules to the support member 500. When disassembling the photovoltaic modules, the locking member 300 is first removed. At this time, the clamping arms 140 are released from the locking member 300. Under external force, the clamping arms 140 can rotate from a first rotation angle to a second rotation angle, thereby causing the clamping arms 140 to disengage from the corresponding frame 400, thus quickly separating the clamping block device from the frame 400 of the photovoltaic module.

[0034] The locking element 300 can be a bolt. The supporting element 500 can be a purlin or main beam on a building.

[0035] In some embodiments, the two latching arms 140 have overlapping portions along a first direction, and the locking member 300 is used to pass sequentially through the overlapping portions of the two latching arms 140 along a second direction to simultaneously lock the two latching arms 140 at a first rotation angle.

[0036] In other embodiments, the locking arms of the two pressure blocks may not overlap. Each locking arm has a semi-circular hole. When the two locking arms are connected to each other, the two semi-circular holes merge into a circular hole. The locking member passes through the circular hole and locks the two locking arms simultaneously at the first rotation angle.

[0037] In some embodiments, combined with Figure 2 and Figure 3 The base 130 includes a base 131 and a side wall 132 disposed at one end of the base 131 along a first direction. The snap-fit ​​arm 140 is disposed on the side of the side wall 132 away from the base 131. The base 131 and the snap-fit ​​arm 140 of the same pressure block 100 are disposed opposite to each other. The two bases 131 have overlapping portions extending along the first direction. The locking member 300 passes through the overlapping portions of the two snap-fit ​​arms 140 and the overlapping portions of the two bases 131 in sequence.

[0038] In this embodiment, the snap-fit ​​arm 140 and the base 131 are respectively disposed at both ends of the side wall 132 along the second direction, and the base 131 and snap-fit ​​arm 140 of the same pressure block 100 are disposed opposite to each other, that is, the pressure block 100 has a semi-enclosed frame structure. The two bases 131 have overlapping portions extending along the first direction, and the two pressure blocks 100 have overlapping portions extending along the first direction, that is, the two pressure blocks 100 are nested together along the first direction, so that the locking member 300 can pass through the overlapping portions of the two snap-fit ​​arms 140 and the overlapping portions of the two bases 131 in sequence along the second direction. In actual use, the sides of the two pressure blocks 100 that are far apart from each other are respectively embedded into the mounting grooves 460 of the two adjacent photovoltaic module frames 400, and part of the base 131 is located on the third side wall 450 of the frame 400. When the locking member 300 is locked, the base 131 can be tightly pressed against the third side wall 450 of the corresponding frame 400.

[0039] In some embodiments, the thickness of the sidewall 132 decreases sequentially along the first direction from the base 131 to the snap-fit ​​arm 140.

[0040] This configuration, by reducing the wall thickness at the connection point between the snap-fit ​​arm 140 and the side wall 132, allows the snap-fit ​​arm 140 to elastically deform relative to the side wall 132, thereby enabling it to switch between the first rotation angle and the second rotation angle.

[0041] In some embodiments, the pressing device includes a support block 200, which is disposed between the snap-fit ​​arm 140 and the base 131 along a second direction, and the locking member 300 passes through the snap-fit ​​arm 140, the support block 200 and the base 131 in sequence along the second direction.

[0042] A support block 200 is disposed between the latching arm 140 and the base 131 to support the latching arm 140 and prevent it from disengaging from the frame 400 when the photovoltaic module is subjected to external loads and the latching arm 140 rotates relative to the side wall 132 to a second rotation angle. The base 131 is disposed on the support member 500, the support block 200 is disposed on the base 131, and the latching arm 140 is disposed on the support block 200. The locking member 300 locks the latching arm 140, the support block 200, and the base 131 simultaneously to the support member 500, thereby simultaneously limiting the latching arm 140 along the first direction and the second direction, thus ensuring that the latching arm 140 is securely locked at the first rotation angle. When disassembling the photovoltaic module, remove the locking piece 300, then move out the support block 200, and then press down on the snap-fit ​​arm 140 so that the snap-fit ​​arm 140 rotates from the first rotation angle to the second rotation angle, that is, the snap-fit ​​arm 140 disengages from the frame 400. At this time, the frame 400 can be removed.

[0043] Furthermore, the two pressure blocks 100 include a first pressure block 110 and a second pressure block 120. The locking arm 140 and the base 131 of the first pressure block 110 are simultaneously sleeved on the locking arm 140 and the base 131 of the second pressure block 120. The locking member 300 passes through the locking arm 140 of the first pressure block 110, the locking arm 140 of the second pressure block 120, the support block 200, the base 131 of the second pressure block 120, and the base 131 of the first pressure block 110 in sequence along the second direction.

[0044] In some other embodiments, the two pressure blocks include a first pressure block and a second pressure block. The locking arm and base of the first pressure block are simultaneously disposed on the locking arm and base of the second pressure block. The locking member passes through the locking arm of the first pressure block, the locking arm of the second pressure block, the support block, the base of the first pressure block and the base of the second pressure block in sequence along the second direction.

[0045] Furthermore, in combination Figure 2 The base 131 of the first pressing block 110 is provided with a first recess 111, and the base 131 of the second pressing block 120 is provided with a first protrusion 121, the first recess 111 and the first protrusion 121 cooperate; and / or, the snap-fit ​​arm 140 of the first pressing block 110 is provided with a second recess 112, and the snap-fit ​​arm 140 of the second pressing block 120 is provided with a second protrusion 122, the second recess 112 and the second protrusion 122 cooperate.

[0046] In this embodiment, when installing the pressing device, the first pressing block 110 is first installed inside the frame 400 of the first photovoltaic module, and then the second pressing block 120 is pushed along the first direction until the first recess 111 engages with the first protrusion 121, and / or the second recess 112 engages with the second protrusion 122. Finally, the support block 200 is installed between the snap-fit ​​arm 140 and the base 131, and then the locking member 300 passes through the snap-fit ​​arm 140, the support block 200, the base 131 and the support member 500 in sequence to fix the pressing device on the support member 500. The first recess 111 engages with the first protrusion 121, and / or the second recess 112 engages with the second protrusion 122, defining the relative positions of the first pressing block 110 and the second pressing block 120 along the first direction, so that the holes on the first pressing block 110 and the second pressing block 120 are aligned, so that the locking member 300 can quickly pass through the first pressing block 110 and the second pressing block 120.

[0047] In some embodiments, the base of the first pressing block has a first recess, and the base of the second pressing block has a first protrusion, with the first recess and the first protrusion engaging. The snap-fit ​​arm of the first pressing block has a second recess, and the snap-fit ​​arm of the second pressing block has a second protrusion, with the second recess and the second protrusion engaging.

[0048] In some other embodiments, the base of the first pressing block is provided with a first recess, and the base of the second pressing block is provided with a first protrusion, the first recess and the first protrusion engaging in the same direction. Alternatively, the snap-fit ​​arm of the first pressing block is provided with a second recess, and the snap-fit ​​arm of the second pressing block is provided with a second protrusion, the second recess and the second protrusion engaging in the same direction.

[0049] In some embodiments, the snap-fit ​​arm 140 is provided with a snap hook 144, which is used to hook with the snap-fit ​​portion 431 on the frame 400.

[0050] In this embodiment, a latching hook 144 is provided on the latching arm 140. When the latching arm 140 is rotated, the latching arm 140 drives the latching hook 144 to move, so that the latching hook 144 disengages from or engages with the latching part 431. The engagement of the latching hook 144 with the latching part 431 enables the latching arm 140 to quickly engage with the frame 400.

[0051] A latching part 431 is provided inside the first sidewall 430 of the frame 400. When the latching arm 140 rotates counterclockwise relative to the sidewall 132, the latching arm 140 drives the latch hook 144 to move upward to the first rotation angle, and the latch hook 144 engages with the latching part 431. When the latching arm 140 rotates clockwise relative to the sidewall 132, the latching arm 140 drives the latch hook 144 to move downward, and the latch hook 144 disengages from the latching part 431.

[0052] In some embodiments, combined with Figure 2 The snap-fit ​​arm 140 includes a snap-fit ​​section 141 and a crimping section 143 connected in sequence. When the snap-fit ​​arm 140 rotates at the first angle, the snap-fit ​​section 141 tilts from the side wall 132 to the side away from the base 131. The snap hook 144 is provided at one end of the snap-fit ​​section 141 near the crimping section 143. The locking member 300 passes through the crimping section 143.

[0053] In this embodiment, when installing the photovoltaic module, the first photovoltaic module is first installed, and then a portion of the first pressing block 110 is embedded into the mounting groove 460 on the frame 400 of the first photovoltaic module. Then, the second pressing block 120 is pushed along the first direction so that a portion of the second pressing block 120 is embedded into the first pressing block 110. The support block 200 is installed and the pressing block device is locked by the locking member 300. Next, the second photovoltaic module is pushed along the first direction towards the side closer to the pressing block device. Since the snap-fit ​​section 141 of the second pressing block 120 is inclined from the side wall 132 to the side away from the base 131, and the snap-fit ​​arm 140 can undergo elastic deformation, the snap-fit ​​portion 431 of the second photovoltaic module can gradually squeeze the snap-fit ​​arm 140 of the second pressing block 120 so that the hook 144 on the snap-fit ​​arm 140 of the second pressing block 120 hooks with the snap-fit ​​portion 431 on the second photovoltaic module. Using the above installation method, after the pressing device is installed, it can be directly locked onto the support 500 by the locking part 300 without repeatedly adjusting the locking part 300.

[0054] Furthermore, a connecting section 142 is provided between the snap-fit ​​section 141 and the crimping section 143. The connecting section 142 is tilted in the opposite direction to the snap-fit ​​section 141, that is, the height of the crimping section 143 is reduced so that the upper part of the locking member 300 does not protrude from the photovoltaic module, thereby improving the aesthetics of the entire photovoltaic system.

[0055] Combination Figure 2 In some embodiments, the base 131 of the first pressing block 110 and the second pressing block 120 are respectively provided with a support portion 1311. The support portion 1311 is used to make there a gap between the two sides of the pressing block device in the first direction OX and the support member 500, so that the third side wall 450 of the frame 400 can be inserted into the gap, thereby pressing the frame 400 onto the support member 500 by the pressing block 100.

[0056] Furthermore, the two support parts 1311 have different heights, that is, the gaps on both sides of the support parts 1311 are different. During installation, the pressure block 100 located on the side with the smaller gap is first embedded into the frame 400 of the first photovoltaic module; then the other pressure block 100 and support block 200 are installed, and the pressure block device is fixed by the locking member 300; finally, the second photovoltaic module is pushed along the first direction OX 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.

[0057] In some embodiments, combined with Figure 2 The base 131 of the first pressing block 110 and the base 131 of the second pressing block 120 each have a slope 1312, and along the direction from the locking member 300 to the side wall 132, the slope 1312 gradually slopes away from the support member 500. The base 131 of the first pressing block 110 and the base 131 of the second pressing block 120 are respectively used to slide into the frame 400 through the slope 1312.

[0058] Specifically, 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 the inclination angle of the inclined surface 1312, so that when the first pressing block 110 is embedded into the mounting groove 460, the inclined surface 1312 and the third sidewall 450 fit together. By setting the inclined surface 1312, the pushing force can be reduced when the base 131 of the second pressing block 120 is pushed into the frame 400 along the first direction OX.

[0059] 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, and a mounting groove 460 is provided on the frame 400. A snap-fit ​​part 431 is provided on the inner wall of the mounting groove 460. The pressing block 100 is used to be embedded into the mounting groove 460 on both sides along the first direction, and the snap-fit ​​parts 431 of two adjacent frames 400 are respectively snapped with two snap-fit ​​arms 140.

[0060] In this embodiment, one end of the first pressing block 110 is embedded in the mounting groove 460 of the first photovoltaic module, and one end of the second pressing block 120 is embedded in the mounting groove 460 of the second photovoltaic module. The locking member 300 simultaneously fixes the first pressing block 110 and the second pressing block 120 to the support member 500, that is, the locking member 300 can simultaneously lock two adjacent photovoltaic modules to the support member 500. At the same time, the two snap-fit ​​arms 140 respectively snap-fit ​​with the snap-fit ​​portions 431 of the two adjacent frame 400 to further enhance the fastening effect on the frame 400. The snap-fit ​​arm 140 is elastically deformable. When installing the first pressure block 110, the snap-fit ​​arm 140 can be pressed to the second rotation angle. At this time, the highest height of the first pressure block 110 along the second direction is less than the slot size of the mounting groove 460, which facilitates the easy insertion of the first pressure block 110 into the mounting groove 460 of the first photovoltaic module. When the snap-fit ​​arm 140 is released, it returns to the first rotation angle and engages with the snap-fit ​​part 431 in the first photovoltaic module. When disassembling the photovoltaic module, the locking member 300 is first removed. At this time, the snap-fit ​​arm 140 is released from the locking member 300. Under the action of external force, the snap-fit ​​arm 140 can rotate from the first rotation angle to the second rotation angle, thereby causing the snap-fit ​​arm 140 to disengage from the corresponding frame 400, and thus quickly separating the pressure block device from the frame 400 of the photovoltaic module.

[0061] 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.

[0062] 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.
