Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a support component and a photovoltaic system using the support component. Background Technology

[0002] With the development of the photovoltaic industry, more and more rooftops with waterproof layers are being fitted with photovoltaic systems. However, for rooftops without pre-installed pipe pile supports, photovoltaic brackets need to be installed before laying the photovoltaic modules. However, in related technologies, installing photovoltaic brackets on the roof poses a risk of water leakage. Utility Model Content

[0003] The main objective of this application is to provide a support assembly designed to improve the waterproofing of roofs.

[0004] To achieve the above objectives, the support assembly proposed in this application includes a chassis, an upper support, a waterproof layer, and an elastic limiting member; the upper support is fixedly installed on the chassis; the waterproof layer is fixedly disposed on the upper support, and the waterproof layer at least covers the side of the upper support away from the chassis, and the waterproof layer covers the chassis; the elastic limiting member is disposed on one of the upper support and the chassis, and the other of the upper support and the chassis has a limiting hole, and a portion of the elastic limiting member is inserted into the limiting hole to limit the upper support.

[0005] In one embodiment, the chassis is detachably connected to the upper support.

[0006] In one embodiment, the chassis is engaged with the upper support.

[0007] In one embodiment, one of the top of the chassis and the bottom of the upper support is provided with a slot, and the other is provided with a boss that engages with the slot.

[0008] In one embodiment, the chassis has a slot, the slot has a first opening and a second opening, the first opening faces upward, and the second opening is adjacent to and communicates with the first opening.

[0009] In one embodiment, the elastic limiting member is installed on the bottom wall and / or the side wall of the slot, the boss is provided with a limiting hole, and a portion of the elastic limiting member is inserted into the limiting hole.

[0010] In one embodiment, the elastic limiting member includes:

[0011] The fixing part is fixedly disposed on the bottom wall or the side wall of the slot; and

[0012] An elastic telescopic part, one end of which is connected to the fixed part, and the other end of which extends into the limiting hole.

[0013] In one embodiment, the bottom wall or side wall of the slot is provided with a threaded hole, and the elastic limiting member is threadedly connected to the threaded hole.

[0014] In one embodiment, at least one of the opposite ends of the boss is chamfered in the orientation direction along the second opening.

[0015] In one embodiment, the chassis includes:

[0016] The disk body has a through hole; and

[0017] Fasteners that pass through the disc body and extend in a direction away from the upper support.

[0018] In one embodiment, the through hole is a through hole, and a gap is provided between the disk body and the bottom of the upper support.

[0019] This application also proposes a photovoltaic system including the aforementioned support assembly, wherein the chassis is used to fix it to the roof, the roof is provided with a waterproof component, and the waterproof layer is thermally fused to the waterproof component.

[0020] The technical solution of this application, by setting a chassis, facilitates the fixed connection between the chassis and the roof, thereby achieving the effect of fixed connection between the support assembly and the roof. By fixing the upper support to the chassis, the photovoltaic bracket can be installed through the upper support. In addition, by fixing the waterproof layer to the upper support and at least covering the side of the upper support away from the chassis, the waterproof layer can effectively waterproof at least the side of the upper support away from the chassis, reducing the risk of rainwater erosion of the upper support, and thus reducing the risk of rainwater entering the support assembly through the connection between the upper support and the chassis. Furthermore, by covering the chassis with the waterproof layer, after hot-air welding of the waterproof layer and the roof's waterproof material, the upper support and the chassis can be jointly wrapped. At this time, even if the upper support tilts due to continuous wind pressure and suction, no obvious gaps will appear between the upper support and the waterproof layer, thereby reducing the risk of water leakage to the roof through the support assembly and improving the waterproof effect of the roof. By placing an elastic limiting member on one of the upper support and the chassis, and providing a limiting hole on the other of the upper support and the chassis, and inserting part of the elastic limiting member into the limiting hole, the upper support can be relatively limited relative to the chassis through the elastic limiting member. This reduces the risk of the upper support sliding relative to the chassis, thereby improving the stability of the waterproof layer and reducing the risk of water leakage to the roof.

[0043] With the development of the photovoltaic industry, more and more rooftops with waterproof layers are being fitted with photovoltaic systems. However, for rooftops without pre-installed pipe pile supports, photovoltaic brackets must be installed before laying the photovoltaic modules. However, related technologies pose a risk of leakage after the photovoltaic brackets are installed on the roof. For example, before laying the photovoltaic modules, an insulation layer is laid on the roof, and then a waterproof layer is laid on top of the insulation layer. The photovoltaic brackets have waterproof membrane, which is typically welded to the waterproof layer on the roof using hot air welding.

[0044] In related technologies, photovoltaic (PV) supports consist of two parts: the lower part is a nail plate structure, which includes a plate body and long screws mounted on the plate body, thus securing the nail plate to the roof. The upper part of the support includes a waterproof disc and a supporting column. The supporting column passes through the waterproof membrane and has a threaded hole at its lower part. The waterproof disc and the nail plate are fastened together with bolts, and the supporting column and the waterproof membrane are laser-welded to prevent leakage. However, during use, due to the continuous action of wind pressure and suction on the support system, the supporting column may tilt locally, and there is still a risk of leakage at the laser-welded joint.

[0045] In order to improve the waterproofing effect of the roof, this application proposes a support assembly.

[0046] Please refer to the reference. Figures 1 to 10 In one embodiment of this application, the support assembly includes a chassis 100, an upper support 200, a waterproof layer 300, and an elastic limiting member 400. The upper support 200 is fixedly installed on the chassis 100. The waterproof layer 300 is fixed to the upper support 200, and the waterproof layer 300 covers at least one side of the upper support 200 away from the chassis 100, and the waterproof layer 300 covers the chassis 100. The elastic limiting member 400 is disposed on one of the upper support 200 and the chassis 100, and the other of the upper support 200 and the chassis 100 is provided with a limiting hole 211. A portion of the elastic limiting member 400 is also inserted into the limiting hole 211 to limit the upper support 200.

[0047] The support assembly in this application is applied to roof 1, which may include a base roof, an insulation layer, and waterproofing material stacked sequentially. For roof 1 without pre-installed tubular supports, a support assembly is typically used to install photovoltaic (PV) brackets, which in turn install PV modules onto the brackets. The base plate 100 is used to fix the support assembly to roof 1, thus achieving the effect of fixing the support assembly to roof 1. For better stability, the base plate 100 can be fixed to the base roof surface of roof 1. The base plate 100 can be circular, rectangular, or other shapes, and can be connected to roof 1 by screws, bolts, or riveting. The upper support 200 is fixedly installed on the base plate 100 and can be used to install the PV brackets. When the upper support 200 is fixedly installed on the base plate 100, it can be connected by screws, bolts, clips, or welding, ensuring good stability after the upper support 200 is connected to the base plate 100. The waterproof layer 300 is fixed to the upper support 200 and at least covers the side of the upper support 200 facing away from the chassis 100. The projection of the waterproof layer 300 onto the roof 1 overlaps the projection of the chassis 100 onto the roof 1. After the waterproof layer 300 is sealed and connected to the waterproof material on the roof 1, it achieves the effect of completely covering both the upper support 200 and the chassis 100. Specifically, the waterproof layer 300 is connected to the waterproof material on the roof 1, for example, by hot air welding or by adhesive bonding. When the waterproof layer 300 is fixed to the upper support 200, it can achieve a good fixed connection with the upper support 200 through methods such as bonding or injection molding. The waterproof layer 300 may only cover the side of the upper support 200 facing away from the chassis 100, or it may cover both the side of the upper support 200 facing away from the chassis 100 and the edge portion of the upper support 200 facing the roof 1. When the waterproof layer 300 covers the upper support 200, it can be adapted to the shape of the upper support 200, thereby facilitating the installation of the photovoltaic bracket and ensuring good stability after the photovoltaic bracket is installed on the upper support 200. Alternatively, the shape of the waterproof layer 300 may differ from that of the upper support 200. For example, the upper support 200 includes a connecting seat connected to the chassis 100 and a fixing seat provided on the connecting seat. The fixing seat is used to fix the photovoltaic bracket, and part of the waterproof layer 300 is adapted to the shape of the fixing seat and covers the fixing seat, thereby facilitating the fixed installation of the photovoltaic bracket. Another part of the waterproof layer 300 covers the connecting seat of the upper support 200, and its shape may differ from the outline of the connecting seat. For example, the connecting seat may be circular, and the part of the waterproof layer 300 used to cover the connecting seat may be rectangular, or the connecting seat may be rectangular, and the part of the waterproof layer 300 used to cover the connecting seat may be circular, etc.

[0048] The elastic limiting member 400 can be connected to the upper support 200, in which case the chassis 100 is provided with a corresponding limiting hole 211, and a portion of the elastic limiting member 400 can extend into the limiting hole 211; or, the elastic limiting member 400 can be connected to the chassis 100, in which case the upper support 200 is provided with a corresponding limiting hole 211. When the elastic limiting member 400 is located between the upper support 200 and the chassis 100, it can be specifically located between the bottom of the upper support 200 and the top of the chassis 100, that is, the elastic limiting member 400 extends in the vertical direction; or the upper support 200 can be sleeved on the chassis 100, in which case the elastic limiting member 400 can also be located between the side wall of the upper support 200 and the side wall of the chassis 100, that is, the elastic limiting member 400 can also extend in the horizontal direction. Taking an elastic limiting member 400 located on the chassis 100 and a limiting hole 211 located on the upper support 200 as an example, the elastic limiting member 400 in this application can be a spring. One end of the spring is fixedly connected to the chassis 100, and the other end can extend into the limiting hole 211 of the upper support 200. Alternatively, the elastic limiting member 400 can include a spring and a limiting post. One end of the spring is fixedly connected to the chassis 100, and the other end is connected to the limiting post. The limiting post can extend into or out of the limiting hole 211 under the elastic extension and contraction of the spring. The shape of the limiting hole 211 can be circular, rectangular, or other shapes.

[0049] The technical solution of this application, by setting up a chassis 100, facilitates the fixed connection between the chassis 100 and the roof 1, thereby achieving the effect of fixed connection between the support assembly and the roof 1. By fixing the upper support 200 to the chassis 100, the photovoltaic bracket can be installed through the upper support 200. In addition, by fixing the waterproof layer 300 to the upper support 200 and at least covering the side of the upper support 200 away from the chassis 100, the waterproof layer 300 can effectively waterproof at least the side of the upper support 200 away from the chassis 100, reducing the risk of rainwater erosion of the upper support 200, and thus reducing the risk of rainwater entering the interior of the support assembly through the connection between the upper support 200 and the chassis 100. Furthermore, since the waterproof layer 300 also covers the chassis 100, after hot-air welding of the waterproof layer 300 and the waterproof material of the roof 1, the upper support 200 and the chassis 100 can be jointly wrapped. Even if the upper support 200 tilts due to continuous wind pressure and suction, there will be no significant gaps between the upper support 200 and the waterproof layer 300, thus reducing the risk of water leakage to the roof 1 through the support assembly and improving the waterproofing effect of the roof 1. By placing the elastic limiting member 400 on one of the upper support 200 and the chassis 100, and providing a limiting hole 211 on the other of the upper support 200 and the chassis 100, with a portion of the elastic limiting member inserted into the limiting hole 211, the upper support 200 can be relatively limited relative to the chassis 100 by the elastic limiting member 400. This reduces the risk of the upper support 200 sliding relative to the chassis 100, thereby improving the stability of the waterproof layer 300 and reducing the risk of water leakage to the roof 1.

[0050] Please refer to the reference. Figures 3 to 10 In one embodiment of this application, the chassis 100 and the upper support 200 are detachably connected.

[0051] By detachably connecting the chassis 100 to the upper support 200, when the upper support 200 is damaged or fails, only the upper support 200, the waterproof layer 300, and the waterproof material on the roof 1 corresponding to the local part of the upper support 200 can be replaced, without having to disassemble and replace the chassis 100, thereby saving replacement costs and simplifying the replacement process.

[0052] Specifically, the chassis 100 and the upper support 200 can be detachably connected by means of screws or snap-fit.

[0053] Please refer to the reference. Figures 3 to 9 In one embodiment of this application, the chassis 100 is snapped into the upper support 200.

[0054] By snapping the chassis 100 to the upper support 200, the need for connecting parts between the chassis 100 and the upper support 200 can be reduced, thereby reducing the number of parts in the support assembly and improving installation efficiency.

[0055] Specifically, when the chassis 100 and the upper support 200 are engaged, one of the chassis 100 and the upper support 200 can be provided with a socket, and the other can be provided with a plug-in block. The plug-in block is inserted into the socket and has an interference fit with the socket, thereby achieving the engagement effect between the chassis 100 and the upper support 200. Alternatively, one of the chassis 100 and the upper support 200 can be provided with a buckle, and the other can be provided with a slot 111. By snapping the buckle into the slot 111, the engagement effect between the chassis 100 and the upper support 200 can be achieved.

[0056] Please refer to the reference. Figures 3 to 10 In one embodiment of this application, one of the top of the chassis 100 and the bottom of the upper support 200 is provided with a slot 111, and the other is provided with a boss 210, which is engaged in the slot 111.

[0057] Specifically, the top of the chassis 100 is provided with a slot 111, and the bottom of the upper support 200 is provided with a boss 210, which engages with the slot 111. Alternatively, the top of the chassis 100 is provided with a boss 210, and the bottom of the upper support 200 is provided with a slot 111, with the boss 210 engaging with the slot 111. During the process of engaging the boss 210 with the slot 111, the boss 210 can be engaged with the slot 111 in the vertical direction; or, the slot 111 has multiple openings, at least one of which is open in the horizontal direction, allowing the boss 210 to engage with the slot 111 in the horizontal direction through the opening of the slot 111.

[0058] By providing a slot 111 on one of the top of the chassis 100 and a boss 210 on the other, and having the boss 210 engage with the slot 111, the chassis 100 and the upper support 200 are connected. In addition, this arrangement facilitates worker operation and improves the installation efficiency of the chassis 100 and the upper support 200.

[0059] Please refer to the reference. Figures 3 to 10 In one embodiment of this application, the chassis 100 is provided with a slot 111, the slot 111 is provided with a first opening 111a and a second opening 111b, the first opening 111a faces upward, and the second opening 111b is adjacent to and connected to the first opening 111a.

[0060] By providing a second opening 111b on the slot 111 that communicates with the first opening 111a, the boss 210 can be inserted into the slot 111 either through the first opening 111a or through the second opening 111b when it is installed in the slot 111.

[0061] Specifically, when the size of the first opening 111a is large enough for the boss 210 to be inserted, the boss 210 can be inserted into the slot 111 from the first opening 111a; or when the inner wall of the first opening 111a of the slot 111 has a limiting strip protruding, the boss 210 can be slid into the slot 111 from the second opening 111b. This allows the boss 210 to be inserted into the slot 111, and also allows the boss 210 inserted into the slot 111 to be limited by the limiting strip on the inner wall of the first opening 111a, thereby reducing the risk of the upper support 200 detaching from the chassis 100 in the vertical direction. Of course, when the inner wall of the first opening 111a of the slot 111 has a limiting strip protruding, the limiting strip can be an elastic strip, and the side of the limiting strip away from the roof 1 can be provided with a guide surface. In this case, the boss 210 can also pass through the first opening 111a and be inserted into the slot 111.

[0062] The opening of the slot 111 in this application is not limited to only the first opening 111a and the second opening 111b. In other examples, the slot 111 may also include a third opening 111c, which is opposite to the second opening 111b and has the opposite orientation. This arrangement allows the boss 210 to slide horizontally into the slot 111 through the third opening 111c, thereby improving the ease of operation for workers installing the chassis 100 and the upper support 200.

[0063] Please refer to the reference. Figures 3 to 11 In one embodiment of this application, the elastic limiting member 400 is installed on the bottom wall and / or the side wall of the slot 111, the boss 210 is provided with a limiting hole 211, and a portion of the elastic limiting member 400 is inserted into the limiting hole 211.

[0064] Specifically, please refer to the following: Figure 7 and Figure 9The elastic limiting member 400 can be installed on the bottom wall of the slot 111. It should be noted that the bottom wall of the slot 111 refers to the wall surface of the slot 111 closest to the roof 1. In this case, the elastic limiting member 400 can elastically extend and retract in the vertical direction. When the elastic limiting member 400 extends and retracts in the vertical direction, it can retract to a position lower than or flush with the bottom wall of the slot 111. At this time, the elastic member is in a state of avoiding the sliding of the boss 210 within the slot 111. When the boss 210 slides within the slot 111 until its limiting hole 211 is vertically aligned with the limiting member, the elastic member extends into the limiting hole 211 under its own elastic force, thereby achieving the effect of limiting the upper support 200 in the horizontal direction, ensuring a good connection between the base 100 and the upper support 200 in the support assembly. Furthermore, this design can reduce the number of steps such as tightening screws, simplifying the operation for workers.

[0065] Alternatively, please refer to the following: Figure 8 and Figure 10 The elastic element can be installed on the side wall of the slot 111. It should be noted that the side wall of the slot 111 refers to the wall adjacent to the bottom wall. In this case, the elastic element can elastically extend and retract in a horizontal direction at an angle to the orientation of the second opening 111b. When the elastic limiting member 400 extends and retracts in a horizontal direction at an angle to the orientation of the second opening 111b, it can retract into the side wall of the slot 111. At this time, the elastic element is in a state of avoiding the sliding of the boss 210 within the slot 111. When the boss 210 slides within the slot 111 until its limiting hole 211 is opposite to the limiting member in the elastic extension and retraction direction of the elastic element, the elastic element extends into the limiting hole 211 under its own elastic force. This achieves the effect of limiting the upper support 200 in the orientation direction of the second opening 111b, ensuring a good connection between the chassis 100 and the upper support 200 in the support assembly. In addition, this setup can reduce the number of steps involved, such as tightening screws, thus simplifying the operation for workers.

[0066] Please refer to the reference. Figures 7 to 11 In one embodiment of this application, the elastic limiting member 400 includes a fixing part 410 and an elastic telescopic part 420. The fixing part 410 is fixedly disposed on the bottom wall or the side wall of the slot 111. One end of the elastic telescopic part 420 is connected to the fixing part 410, and the other end extends into the limiting hole 211.

[0067] The fixing part 410 is used to fix to the bottom wall or side wall of the slot 111. The fixing part 410 can be connected to the slot 111 via a threaded connection. For example, the bottom wall or side wall of the slot 111 has a threaded hole, and the fixing part 410 has an external thread. By threading the fixing part 410 into the threaded hole, a fixed connection is achieved between the fixing part 410 and the bottom wall or side wall of the slot 111. Alternatively, the fixing part 410 can also be connected to the slot 111 via a snap-fit ​​connection. Alternatively, a through hole can be provided in the slot 111, and the fixing part 410 can be inserted into the through hole. The fixing part 410 and the through hole can be press-fitted, bonded with adhesive, or welded to achieve a stable connection.

[0068] The elastic telescopic part 420 can be a spring, or the elastic telescopic part 420 can include an elastic element and a limiting post. The elastic element is installed on the fixed part 410, and the limiting post is connected to the elastic element, so that the limiting post is inserted into the limiting hole 211 of the boss 210 or disengaged from the limiting hole 211 under the action of the elastic element.

[0069] This design makes the connection between the elastic limiting member 400 and the bottom wall or side wall of the slot 111 more secure.

[0070] In one embodiment of this application, the bottom wall or side wall of the slot 111 is provided with a threaded hole, and the elastic limiting member 400 is threadedly connected to the threaded hole.

[0071] This design facilitates a secure connection between the elastic limiting member 400 and the bottom wall or side wall of the slot 111. Furthermore, it allows for easy replacement of the elastic limiting member 400 should it be damaged.

[0072] Please refer to the reference. Figure 7 and Figure 8 In one embodiment of this application, at least one of the opposite ends of the boss 210 is provided with a chamfer 212 in the orientation direction along the second opening 111b.

[0073] This configuration allows the boss 210 to slide along the chamfer 212 of the boss 210 and compress into the wall of the slot 111 when it is inserted into the slot 111 through the second opening 111b. This provides clearance for the boss 210 to continue sliding in the slot 111 in the opposite direction to the second opening 111b, thus facilitating the smooth insertion of the boss 210 into the slot 111.

[0074] Please refer to the reference. Figure 9 and Figure 10In one embodiment of this application, the chassis 100 includes a chassis body 110 and a fastener 120. The chassis body 110 is provided with a through hole 112. The fastener 120 passes through the chassis body 110 and extends in a direction away from the upper support 200.

[0075] Specifically, the disc body 110 can be circular or rectangular, etc. The fastener 120 can be a screw or a bolt.

[0076] By inserting the fastener 120 through the disc body 110 and extending it away from the upper support 200, it is easy to securely connect the fastener 120 to the roof 1, thereby achieving a stable connection between the chassis 100 and the roof 1.

[0077] Please refer to the reference. Figure 3 , Figure 9 and Figure 10 Furthermore, the through hole 112 is a through hole, and a gap 10 is provided between the disk body 110 and the bottom of the upper support 200.

[0078] It is understood that the roof 1 may include a base roof, an insulation layer, and waterproofing material stacked sequentially. Fasteners 120 can be securely connected to the base roof, for example, by threaded connection. The disc body 110 overlaps the waterproofing material on the side furthest from the base roof. However, in actual use, the insulation layer may easily deform and arch upwards.

[0079] By setting the through hole 112 as a through hole and providing a gap 10 between the bottom of the disc body 110 and the upper support 200, the disc body 110 can move up and down along the axis of the fastener 120 under the influence of the insulation layer and waterproof material of the roof 1, thereby reducing the risk of moving the fastener 120 and thus reducing the risk of the roof 1 being damaged due to the fastener 120 pulling on the base roof surface.

[0080] Specifically, in order to provide a gap 10 between the bottom of the disc body 110 and the upper support 200, when the fastener 120 is fastened to the roof 1, the top of the fastener 120 is set higher than the top of the disc body 110. At this time, the upper support 200 can abut against the fastener 120, and form the aforementioned gap 10 with the disc body 110.

[0081] This application also proposes a photovoltaic system, such as Figure 1As shown, the photovoltaic system includes a support assembly, the specific structure of which is as described in the above embodiments. Since this photovoltaic system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The chassis 100 is used to fix the system to the roof 1, which includes a base roof and a waterproof component disposed on the base roof. The waterproof layer 300 is thermally fused to the waterproof component.

[0082] The chassis 100 and the roof 1 can be connected by screws, bolts, or riveting to improve the stability of the connection. The roof 1 is equipped with a waterproof component, which can be a layered structure, a plate structure, or other structures. The material of the waterproof component can be the same as that of the waterproof layer 300, so that the connection effect is better after the waterproof layer 300 and the waterproof component are heat-fused together.

[0083] Furthermore, the roof 1 also includes an insulation layer, which is disposed between the base roof surface and the waterproofing components. The support assembly also includes a fastener 120, one end of which is connected to the chassis, and the other end passes through the waterproofing components and the insulation layer and is connected to the roof 1. The fastener 120 can be a screw or bolt, etc. This arrangement ensures a stable connection between the chassis 100 and the roof 1.

[0084] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
