Description

Technical Field

[0001] The utility model relates to an integrated rooftop photovoltaic device. Background Art

[0002] Photovoltaic power generation is a clean energy that converts solar energy into electrical energy. Among existing technologies, the main method promoted among residents is rooftop photovoltaic power generation, which occupies the roof structure but not the effective area on the ground.

[0003] In the existing technology, photovoltaic power generation on the roof is installed by drilling holes on the original roof. The stability of the hole-punching installation is relatively poor. Since the windward area of ​​the roof is large, this type of fixing method is very likely to loosen at the connection position, causing the bracket to loosen and break, and eventually causing the photovoltaic panel to fall, which poses certain risks.

[0004] Based on the above problems, we designed a roof-integrated photovoltaic device that is cast into one piece with the roof and has a more stable and reliable fixation. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a roof-integrated photovoltaic device which is cast in one piece with the roof and has a more stable and reliable fixation.

[0006] The utility model is realized through the following technical solutions:

[0007] A roof-integrated photovoltaic device includes a photovoltaic panel and a bracket device supported on both sides of the photovoltaic panel. The bracket device includes a bracket group cast on the roof and a clamping member rotatably installed by the bracket group. The steel bars cast in the roof pass through the bracket group.

[0008] Preferably, the bracket group includes two bracket plates, which are symmetrically arranged, and the bottom of the bracket plate is bent to form a support portion. A connecting plate is provided between the two bracket plates, and a first anchor hole is provided on the plate surface of the connecting plate, and a second anchor hole is provided on the plate surface of the bracket plate. The first anchor hole and the second anchor hole are staggered, and the steel bars passing through the first anchor hole and the second anchor hole are staggered up and down between the two bracket plates; a penetrating assembly hole is provided near the top position of the outer wall of the bracket plate, and the clamping member is installed through the assembly hole.

[0009] Preferably, a sealing base made of rubber is sleeved between the two bracket plates, and the sealing base is interference fit with the bracket plates. During installation, the bottom of the sealing base acts on the top of the cast roof.

[0010] Preferably, the clamping member includes a sleeve, a telescopic tube group and a clamping plate. The sleeve is assembled between the two bracket plates and corresponds to the assembly hole. A stop washer is clamped between the sleeve and the bracket plate. A locking bolt is provided between the bracket plate and the sleeve. After the locking bolt is tightened, the sleeve is clamped and fixed. The telescopic tube group is arranged on the outside of the sleeve, and the clamping plate is installed through the telescopic tube group.

[0011] Preferably, the telescopic tube group includes a bottom tube and a movable tube, the bottom of the bottom tube is connected to the sleeve, the movable tube is inserted into the bottom tube, the upper end of the movable tube is connected to the clamping plate, and a slide groove is vertically provided on the outer wall of the bottom tube. A first locking bolt is fitted between the movable tube and the bottom tube, and the first locking bolt slides vertically along the slide groove.

[0012] Preferably, the clamping plate includes a base plate, two side plates are arranged on the top of the base plate, a top plate is installed through the side plates, and locking screws are fitted between the top plate and the side plates; the photovoltaic panel is supported by the base plate and limited by the side plates, and the photovoltaic panel is clamped between the base plate and the top plate.

[0013] Preferably, anti-slip pads are embedded on the opposite surfaces of the bottom plate and the top plate, and the surfaces of the anti-slip pads are provided with ridges, and the photovoltaic panels are supported by the ridges.

[0014] Preferably, a plurality of supporting feet are provided at the bottom of the supporting portion, and the diameters of the supporting feet gradually decrease downwards.

[0015] There are two ways to install this device:

[0016] The first one is for roofs that have already been built. For roofs that have already been built, it is necessary to drill holes in the roof and plant rebar after drilling. One end of the rebar is vertically bent and inserted into the hole on the roof, and the other end passes through the first rebar hole or the second rebar hole. Then, an outer mold is built on the roof, and concrete is poured in the outer mold. The bracket group is cast and fixed. After casting and fixing, waterproof paint needs to be applied at the casting position. If conditions permit, it can also be covered with waterproof membrane.

[0017] The second method is to fix the bracket group directly to the roof steel bar when inserting the roof steel bar, according to the installation position of the photovoltaic panel, and then cast the bracket group together.

[0018] The first construction method is more complicated, so this device is mainly applicable to roofs under construction.

[0019] For areas that are affected by wind speeds of level 7 or above all year round, the first fixing method needs to be used for roofs that have already been built.

[0020] The beneficial effects of the utility model are:

[0021] This device connects the bracket group with the roof steel bars. After pouring, the bracket group and the roof are connected to form a whole, which has very high stability and avoids loosening. It can effectively support and reinforce the photovoltaic panels and is particularly suitable for installation and use in areas with strong winds. In addition, this device can fine-tune the pitch angle of the photovoltaic panels, allowing the photovoltaic panels to receive sunlight for longer periods of time and increase power generation. The structure of this device is simple and suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1 、 Figure 2 and Figure 3 A roof-integrated photovoltaic device is shown, comprising a photovoltaic panel 1 and a bracket device 2 supported on both sides of the photovoltaic panel 1. The bracket device 2 comprises a bracket group 21 cast on the roof, and a clamping member 22 rotatably installed through the bracket group 21. The steel bars 3 cast in the roof pass through the bracket group 21.

[0035] In the above technical solution, the bracket group 21 is fixed together with the steel bars when pouring the roof, and then the bracket group 21 is cast and fixed by pouring, so that the bracket group 21 and the roof form an integrated structure, the structure is more stable, and then the photovoltaic panel 1 is clamped with the clamping member 22, which makes the installation simple.

[0036] See Figure 4 and Figure 5As shown, the bracket group 21 includes two bracket plates 210, and the two bracket plates 210 are symmetrically arranged. The bottom of the bracket plate 210 is bent to form a support portion 211, and a connecting plate 212 is arranged between the two bracket plates 210. A first anchor hole 213 is penetrated on the plate surface of the connecting plate 212, and a second anchor hole 214 is penetrated on the plate surface of the bracket plate 210. The first anchor hole 213 and the second anchor hole 214 are staggered, and the steel bars 3 passing through the first anchor hole 213 and the second anchor hole 214 are staggered up and down between the two bracket plates 210; a penetrating assembly hole (not shown) is provided near the top position of the outer wall of the bracket plate 210, and the clamping member 22 is installed through the assembly hole.

[0037] In the above technical solution, the support portion 211 formed by bending can allow the bracket plate 210 to be firmly cast into the roof after casting and solidification to prevent it from falling out.

[0038] The steel bars 3 can be passed through the first anchoring holes 213 and the second anchoring holes 214 , thereby further increasing the firmness of the support plate 210 .

[0039] See Figure 4 As shown, a sealing base 232 made of rubber is sleeved between the two bracket plates 210. The sealing base 232 and the bracket plates 210 are interference fit. During installation, the bottom of the sealing base acts on the top of the cast roof.

[0040] See Figure 4 and Figure 6 As shown, the clamping member 22 includes a sleeve 220, a telescopic tube group 221 and a clamping plate 222. The sleeve 220 is assembled between the two bracket plates 210 and corresponds to the assembly hole. A stop washer 223 is clamped between the sleeve 220 and the bracket plate 210. A locking bolt 224 is provided between the bracket plate 210 and the sleeve 220. After the locking bolt 224 is tightened, the sleeve 220 is clamped and fixed. The telescopic tube group 221 is arranged on the outside of the sleeve 220, and the clamping plate 222 is installed through the telescopic tube group 221.

[0041] In the above technical solution, the requirement of tilting installation of the photovoltaic panel 1 can be met by adjusting the length of the telescopic tube group 221 and rotating the sleeve 220 along the locking bolt 224.

[0042] On a flat roof, the length-adjustable telescopic tube set 221 can also be adjusted to level the clamping plate 222 to maintain the horizontal installation requirement of the photovoltaic panel 1.

[0043] See Figure 6As shown, the telescopic tube group 221 includes a bottom tube 2210 and a movable tube 2211. The bottom of the bottom tube 2210 is connected to the sleeve 220, the movable tube 2211 is inserted into the bottom tube 2210, and the upper end of the movable tube 2211 is connected to the clamping plate 222. A slide groove 2212 is vertically provided on the outer wall of the bottom tube 2210. A first locking bolt 2213 is fitted between the movable tube 2211 and the bottom tube 2210, and the first locking bolt 2213 slides vertically along the slide groove 2212.

[0044] In the above technical solution, the height of the clamping plate is adjusted by sliding the movable tube up and down along the bottom tube. After the adjustment is completed, the movable tube is locked by the first locking bolt 2213 to keep the position of the movable tube fixed.

[0045] See Figure 6 As shown, the clamping plate 222 includes a base plate 2220, two side plates 2221 are arranged on the top of the base plate 2220, a top plate 2222 is installed through the side plates 2221, and locking screws 2223 are fitted between the top plate 2222 and the side plates 2221; the photovoltaic panel 1 is supported by the base plate 2220 and limited by the side plates 2221, and the photovoltaic panel 1 is clamped between the base plate 2220 and the top plate 2222.

[0046] In the above technical solution, the cooperation between the bottom plate and the top plate can meet the installation and fixation requirements of photovoltaic panels of different thicknesses.

[0047] See Figure 6 As shown, anti-skid pads 2224 are embedded on the opposite surfaces of the bottom plate 2220 and the top plate 2222 , and ridges 2225 are provided on the surface of the anti-skid pads 2224 , which support the photovoltaic panel 1 through the ridges 2225 .

[0048] In the above technical solution, the ridges 2225 can play a role of spacing, and secondly increase the anti-slip property after being fixed to the photovoltaic panel 1.

[0049] See Figure 5 As shown, a plurality of supporting feet 299 are provided at the bottom of the supporting portion 211 , and the diameter of the supporting feet 299 gradually decreases downward.

[0050] In the above technical solution, the support legs 299 can be used to separate the bottom of the support part 211 from the bottom formwork when pouring the roof, thereby playing a supporting role and facilitating the pouring of concrete; under the supporting effect of the above support legs 299, the steel bars built in the roof formwork are suspended, avoiding the exposed steel bars after pouring.

Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
