Description
Technical Field
[0001] This application relates to the technical field of photovoltaic module installation, particularly to a roofing BIPV waterproof bracket and a fastener for fixing a water trough. Background Art
[0002] BIPV, i.e., Building Integrated PV, is building-integrated photovoltaics. PV is Photovoltaic. BIPV technology is a technology that integrates solar power generation (photovoltaic) products into buildings. BIPV is suitable for most buildings, and can be installed in various forms such as flat roofs, pitched roofs, curtain walls, ceilings, etc. However, at the top of a building with building-integrated photovoltaics, there are gaps between adjacent two photovoltaic panels, and rainwater will fall into these gaps when it rains. Therefore, an M-shaped water trough is generally provided at the bottom of the photovoltaic module.
[0003] In related technologies, a roofing BIPV waterproof bracket generally includes a fastener. After the fastener is pressed against the M-shaped water trough, it is then locked to a cross beam by bolts, that is, the M-shaped water trough is fixed by the friction force between the fastener and the cross beam.
[0004] However, when the angle of the house or the construction angle of the power station is too large, there is a risk of the M-shaped water trough slipping when the fastener is not pressed tightly or the worker forgets to lock the fastener. Summary of the Utility Model
[0005] Based on this, in view of the problem that the M-shaped water trough is prone to slipping, it is necessary to provide a roofing BIPV waterproof bracket and a fastener for fixing a water trough.
[0006] A fastener for fixing a water trough, the fastener is used to fix the water trough to a cross beam, and the fastener includes:
[0007] A first side wall, which is used to be arranged on the cross beam and fixedly connected to the cross beam;
[0008] A second side wall, which is arranged at an angle with the first side wall, the second side wall is used to be connected to the outer wall of the water trough, and a stop structure is arranged on the first side wall, the stop structure is used to cooperate with the higher side of the cross beam along the roof slope direction to limit the downward sliding of the water trough.
[0009] In one embodiment, the stop structure is a stop member, and the stop member is located on the higher side of the cross beam along the roof slope direction.
[0010] In one embodiment, the stop member is a baffle or a block.
[0011] In one embodiment, the fastener includes at least two support walls for supporting on the cross beam, the at least two support walls are arranged at intervals along the length direction of the cross beam, and are located on the side of the first side wall away from the second side wall;
[0012] Along the length direction of the cross beam, the support wall close to the second side wall is used to be crimped in the groove on the side wall of the water tank.
[0013] In one embodiment, the first side wall is used to be connected with the cross beam by a plastic wing nut.
[0014] In one embodiment, the stop structure is a U-bolt. The first side wall has connecting sections extending out of the cross beam respectively on both sides along the length direction of the water tank, and both ends of the U-bolt pass through the two connecting sections respectively to be connected with the cross beam.
[0015] In one embodiment, the second side wall is used to be connected with the water tank by a nut.
[0016] In one embodiment, a through hole is formed on one of the second side wall and the water tank, and a convex part is arranged on the other one, and the convex part is used to cooperate with the through hole.
[0017] A roofing BIPV waterproof bracket includes a cross beam, a water tank and a water tank fixing fastener. The cross beam is used to be fixed on the roof. The water tank is fixed on the cross beam by the fastener, and the photovoltaic module is used to be arranged on the water tank.
[0018] In one embodiment, the water tank is an M-shaped water tank. The outer wall of the M-shaped water tank is turned up to form a groove. The fastener has a support wall, and the support wall is located on the side of the first side wall far from the second side wall, and the support wall is crimped in the groove.
[0019] For the above-mentioned roofing BIPV waterproof bracket and the fastener for fixing the water tank, the second side wall is used to cooperate with or be connected to the outer wall of the water tank. At the same time, the first side wall is fixedly connected with the cross beam, that is, the fastener directly connects the cross beam and the water tank, so as to avoid the problem of the water tank slipping caused by the large slope of the roof or the water tank not being tightly pressed. In addition, a stop structure is arranged on the first side wall, and the stop structure is used to cooperate with the cross beam along the inclined direction of the water tank, that is, when the worker forgets to lock the fastener, when the water tank slides along the roof until the stop structure cooperates with the cross beam, the cross beam can prevent the water tank from further sliding down through the fastener, further reducing the risk of the water tank slipping.

[0032] Along the slope direction of the roof, a plurality of cross beams 300 are arranged in sequence on the BIPV roof. The water trough 200 extends along the slope direction of the roof, and the water trough 200 is vertically arranged on the plurality of cross beams 300 and is fixedly connected to each cross beam 300 through a fastener 100. In the related art, generally only the water trough 200 is crimped on the cross beam 300 through the fastener 100. However, for a roof with a relatively large inclination angle, when the fastener 100 is not tightened or the worker forgets to lock the fastener 100, there is a risk of the water trough 200 slipping.
[0033] Refer to Figure 1 and Figure 2An embodiment of the present application provides a fastener 100 for fixing a water tank. The fastener 100 is used to fix the water tank 200 on the beam 300. The fastener 100 includes a first side wall 110 and a second side wall 120. The first side wall 110 is used to be arranged on the beam 300 and fixedly connected to the beam 300. The second side wall 120 is arranged at an angle with the first side wall 110. The second side wall 120 is used to be connected to the outer wall of the water tank 200. The first side wall 110 is provided with a stopper structure, which is used to cooperate with the side of the beam 300 that is higher along the roof slope direction to limit the water tank 200 from sliding down.
[0034] In this embodiment, the second side wall 120 is used to cooperate with or connect with the outer wall of the water tank 200, and the first side wall 110 is fixedly connected with the cross beam 300, that is, the fastener 100 directly connects the cross beam 300 with the water tank 200, so as to avoid the problem of the water tank 200 sliding down due to the large slope of the roof or the water tank 200 not being pressed. In addition, a stop structure is provided on the first side wall 110, and the stop structure is used to cooperate with the side of the cross beam 300 that is higher along the roof slope direction, that is, when the worker forgets to lock the fastener 100, when the water tank 200 slides along the roof until the stop structure cooperates with the cross beam 300, the cross beam 300 can prevent the water tank 200 from sliding down further through the fastener 100, further reducing the risk of the water tank 200 sliding down.
[0035] Specifically, the angle between the second side wall 120 and the first side wall 110 is related to the structure of the water tank. For example, when the water tank is an M-shaped water tank, the second side wall 120 is perpendicular to the first side wall 110. That is, as long as the first side wall 110 can be fixedly connected to the beam 300, the second side wall 120 can be connected to the outer wall of the water tank 200.
[0036] In some embodiments, the stop structure is a stopper 150 , and the stopper 150 is located on a higher side of the beam 300 along the roof slope direction.
[0037] In some embodiments, along the slope direction of the roof, the cross beam 300 has a higher side and a lower side. When the fastener 100 is installed, the side of the fastener 100 with the stopper 150 is located outside the higher side of the cross beam 300. At this time, when the gutter 200 slides down, the higher side wall of the cross beam 300 contacts the stopper 150 to limit the downward movement of the fastener 100. At the same time, since the second side wall 120 of the fastener 100 is connected to the outer wall of the gutter 200, the cross beam 300 can prevent the gutter 200 from sliding down further through the stopper 150.
[0038] In another embodiment, stoppers 150 are respectively arranged on both sides of the second side wall 120 along the inclined direction of the water tank 200. When installing the mounting fastener 100, there is no need to distinguish the installation direction of the stopper 150 on the fastener 100, which simplifies the installation steps. When the water tank 200 slides down, the stopper 150 located on the side of the cross beam 300 close to the ridge is used to prevent the water tank 200 from sliding further.
[0039] In some embodiments, the stopper 150 is a baffle or a stop block.
[0040] In some of these embodiments, when the stopper 150 is a stop baffle, combined Figure 2 , in order to reduce consumables, the stop baffle is arranged on one side of the second side wall 120 along the inclined direction of the water tank 200. During use, the stop baffle is located on the side of the cross beam 300 close to the ridge.
[0041] In some other embodiments, when the stopper 150 is a stop block, combined Figure 4 , a stop block is arranged on one side of the second side wall 120 along the inclined direction of the water tank 200, or stop blocks are respectively arranged on both sides of the second side wall 120 along the inclined direction of the water tank 200, combined Figure 3 .
[0042] In some embodiments, combined Figure 1 and Figure 5 , the fastener 100 includes at least two support walls for supporting on the cross beam 300. The at least two support walls are arranged at intervals along the length direction of the cross beam 300 and are located on the side of the first side wall 110 away from the second side wall 120. Along the length direction of the cross beam 300, the support wall close to the second side wall 120 is used to press-fit into the groove 220 on the side wall of the water tank 200.
[0043] Specifically, the fastener 100 includes a first support wall 130 and a second support wall 140. The first support wall 130 is in the same plane as the second side wall 120. The second side wall 120 is located above the first side wall 110, and the first support wall 130 is located below the second side wall 120. The water tank 200 is an M-shaped water tank 200, and the bottom of the side wall of the M-shaped water tank 200 is turned outwards to form a groove 220. During installation, the first support wall 130 is inserted into the groove 220, and then the fastener 100 is tightly fastened to the cross beam 300 through bolts, that is, the first support wall 130 can be pressed tightly in the groove 220.
[0044] Among them, setting at least two support walls is used to make the bottom of the fastener 100 form a stable support with the cross beam 300. At the same time, in order to increase the anti-slip property of the support wall, anti-slip strips can be arranged at the bottom of the support wall, or the roughness of the bottom surface of the support wall can be increased, or the contact area between the support wall and the cross beam 300 can be increased.
[0045] In some embodiments, the first side wall 110 is used to connect with the cross beam 300 through a plastic wing nut. Among them, the cross beam 300 is in a portal structure and cannot be directly connected to the fastener 100 by bolts. Therefore, a plastic wing nut can be used to fix the fastener 100 to the cross beam 300.
[0046] In some other embodiments, combined Figure 4 , the stop structure is a U-bolt. The first side wall 110 has connecting sections 112 that extend out of the cross beam 300 on both sides along the length direction of the water tank 200, and both ends of the U-bolt pass through the two connecting sections 112 respectively to connect with the cross beam 300.
[0047] In this embodiment, through holes 111 are respectively formed on the two connecting sections 112. During installation, directly make the two ends of the U-bolt pass through the two through holes 111 respectively, and lock the two ends with nuts, then the connection between the fastener 100 and the cross beam 300 can be realized. At the same time, the U-bolt can serve as a stop structure. When the water tank 200 slides down, the cross beam 300 can limit the movement of the fastener 100 through the U-bolt. At the same time, since the fastener 100 is fixed to the water tank 200, the further sliding of the water tank 200 can be prevented.
[0048] In some embodiments, the second side wall 120 is fixedly connected to the water tank 200. Specifically, the second side wall 120 is used to connect with the water tank 200 through a nut. Of course, the second side wall 120 can also be welded, bonded or connected to the water tank 200 through straps.
[0049] In some other embodiments, combined Figure 5 , a through hole 210 is formed on one of the second side wall 120 and the water tank 200, and a protrusion 121 is provided on the other, and the protrusion 121 is used to cooperate with the through hole 210. During installation, insert the protrusion 121 into the through hole 210. When the water tank 200 is not pressed tightly, the dragging effect of the protrusion 121 on the through hole 210 can also play a role in preventing the water tank 200 from slipping.
[0050] Among them, it can be that a through hole 210 is formed on the second side wall 120, and a protrusion 121 is provided on the water tank 200, and the protrusion 121 is used to cooperate with the through hole 210.
[0051] Or, it can also be that a through hole 210 is formed on one of the water tanks 200, and a protrusion 121 is provided on the second side wall 120, and the protrusion 121 is used to cooperate with the through hole 210.
[0052] An embodiment of the present application discloses a roofing BIPV waterproof bracket, which includes a cross beam 300, a water trough 200, and a water trough fixing fastener 100. The cross beam 300 is used to be fixed on the roof. The water trough 200 is fixed on the cross beam 300 through the fastener 100, and a photovoltaic module is to be arranged on the water trough 200.
[0053] In this embodiment, the cross beam 300 is used to be fixed on the roof. The water trough 200 is fixed on the cross beam 300 through the fastener 100. The photovoltaic module is arranged on the water trough 200, and the gap between two adjacent photovoltaic modules is located on the water trough 200. When rainwater flows downward along the gap between two adjacent photovoltaic modules, it can be collected by the water trough 200, preventing the situation of rain leakage.
[0054] The second side wall 120 is used to cooperate with or connect to the outer wall of the water trough 200. At the same time, the first side wall 110 is fixedly connected to the cross beam 300, that is, the fastener 100 directly connects the cross beam 300 and the water trough 200, thus being able to avoid the problem of the water trough 200 slipping due to a large slope of the roof or the water trough 200 not being tightly pressed. In addition, a stop structure is arranged on the first side wall 110. The stop structure is used to cooperate with the cross beam 300 along the inclined direction of the water trough 200, that is, when the worker forgets to lock the fastener 100, when the water trough 200 slides along the roof until the stop structure cooperates with the cross beam 300, the cross beam 300 can prevent the water trough 200 from further sliding through the fastener 100, further reducing the risk of the water trough 200 slipping.
[0055] In some embodiments, combined with Figure 5 , the water trough 200 is an M-shaped water trough 200. The outer wall of the M-shaped water trough 200 is turned up to form a groove 220. The fastener 100 has a support wall, and the support wall is located on the side of the first side wall 110 away from the second side wall 120, and the support wall is crimped in the groove 220.
[0056] Specifically, the fastener 100 includes a first support wall 130 and a second support wall 140. The first support wall 130 and the second side wall 120 are on the same wall surface. The second side wall 120 is located above the first side wall 110, and the first support wall 130 is located below the second side wall 120. The water trough 200 is an M-shaped water trough 200, and the bottom of the side wall of the M-shaped water trough 200 is turned outwards to form a groove 220. During installation, the first support wall 130 is inserted into the groove 220, and then the fastener 100 is tightly fastened to the cross beam 300 through bolts, that is, the first support wall 130 can be pressed tightly in the groove 220.
[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.
[0058] The embodiments described above merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
