Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic components, and specifically to a bracket connection component and a photovoltaic bracket. Background Art

[0002] Photovoltaic brackets are special brackets used to install and support photovoltaic modules. They are generally customized according to the size and shape of photovoltaic modules to meet the installation requirements in different environments. Generally, photovoltaic brackets are fixed on the ground, roof or other structures to keep the photovoltaic modules at a certain tilt angle to maximize the reception of solar radiation. At present, when photovoltaic modules are installed on the slope of the roof color steel tiles. Figure 1 As shown, the square steel beam 1 is fixed to the inclined surface of the color steel tile, and then the metal connecting plate 2 is fixed to the square steel beam 1 by bolts, and finally the photovoltaic module 1 is fixed to the metal connecting plate 2. The advantages of using the above-mentioned square steel beam 1 and metal connecting plate 2 to directly install the photovoltaic module on the inclined surface of the roof color steel tile are mainly as follows: First, use the existing structure: for the inclined roof, the inclination angle of the roof can be directly used, and there is no need to build an additional three-dimensional bracket to adjust the angle of the photovoltaic module, which can save materials and installation costs. Second, simplify the installation process: directly fixing the square steel and photovoltaic modules on the inclined roof can simplify the installation process, reduce installation time and labor intensity. Third, aesthetics: directly installing photovoltaic modules on the inclined roof can make the modules and the roof integrated and maintain the aesthetics of the building. Fourth, windproof effect: for light roofs such as color steel tiles, directly paving photovoltaic modules can provide better windproof effect, because the contact area between the modules and the roof is larger and the fixation is more secure.

[0003] However, the above installation method has the following problems: First, after the photovoltaic module 3 is installed in place, it is very troublesome to adjust the installation position again. Second, since the photovoltaic module 3 is in hard contact with the metal connecting plate 2, in a large temperature difference environment, due to the different expansion coefficients between the photovoltaic module 3 and the metal connecting plate 2, stress deformation will occur between the two, which is easy to cause deformation and damage of the photovoltaic module 3.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that, in the description of the present application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0035] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0036] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.

[0037] like Figure 1-Figure 7 As shown, the present application provides a technical solution: a bracket connection assembly, used to connect the square steel beam 1 and the photovoltaic module 3, including an auxiliary frame 4, a supporting connector 5, an elastic member 8 and a limiting mechanism; the supporting connector 5 is installed on the bearing surface of the square steel beam 1, and extends along the length direction of the square steel beam 1; a card slot 403 is provided on the auxiliary frame 4, and the card slot 403 extends from one end of the auxiliary frame 4 to the other end thereof, and a card block mechanism adapted to the card slot 403 is provided on the supporting connector 5, and the card slot 403 cooperates with the card block mechanism so that the auxiliary frame 4 can slide relative to the supporting connector 5; the limiting mechanism is installed between the auxiliary frame 4 and the supporting connector 5, and is used to limit the sliding of the auxiliary frame 4 relative to the supporting connector 5; the elastic member 8 is provided on the auxiliary frame 4, and is used to carry and connect the photovoltaic module 3.

[0038] In this embodiment, when the photovoltaic module 3 is installed on the color steel tile of the roof, the square steel beam 1 is fixed to the color steel tile by welding or bolts. At this time, the square steel beam 1 is parallel to the color steel tile, that is, the square steel beam 1 is in an inclined state. Then the support connector 5 is fixed to the bearing surface of the square steel beam 1, that is, the upper surface of the square steel beam 1. Then, the card slot 403 on the auxiliary frame 4 is aligned with the card block mechanism of the support connector 5 and the auxiliary frame 4 is pushed to the specified position, and then the limit mechanism is used to limit the sliding of the auxiliary frame 4 relative to the support connector 5, and finally the photovoltaic module 3 is installed on the elastic member 8.

[0039] It should be noted that in the past, the photovoltaic module 3 was pasted onto the metal connecting plate 2, and the metal connecting plate 2 was fixed to the square steel beam 1 with bolts. When the installation position of the photovoltaic module 3 relative to the square steel beam 1 is subsequently changed, the bolts can only be removed first, the metal connecting plate 2 can be removed, and then the square steel beam 1 can be re-punched, and then the metal connecting plate 2 can be re-installed to the new hole position with bolts. The process of changing the position is relatively cumbersome, and because the photovoltaic module 3 and the metal connecting plate 2 are directly attached to each other, in a large temperature difference environment, the expansion coefficients between the photovoltaic module 3 and the metal connecting plate 2 are different, which makes the photovoltaic module 3 easy to deform.

[0040] It should be clear that in the present embodiment, compared with the installation method of using the metal connecting plate 2 to fix the photovoltaic module 3, in the present embodiment, since the auxiliary frame 4 and the supporting connector 5 can slide relative to each other, after the restriction of the auxiliary frame 4 and the supporting connector 5 by the limiting mechanism is released, the relative position of the auxiliary frame 4 and the supporting connector 5 can be changed again, and finally the limiting mechanism can be used to re-restrict the auxiliary frame 4 and the supporting connector 5. In this way, the installation position of the photovoltaic module 3 can be flexibly changed, and the steps for changing the position are simple and easy to operate.

[0041] Secondly, since the elastic member 8 is elastic, it can compensate to a certain extent for the difference in thermal expansion and contraction between the photovoltaic module 3 and the auxiliary frame 4 caused by temperature changes, thereby avoiding stress deformation of the photovoltaic module 3 .

[0042] In addition, the use of the bracket connection assembly can make it easier and faster to install the photovoltaic assembly 3 on the square steel beam 1, thereby improving the efficiency of installation and disassembly.

[0043] In the embodiments of the present application, Figure 2 and Figure 3 As shown, the supporting connector 5 includes a bottom plate 501, a vertical plate 502, a top plate 503 and two side blocks 504 connected in sequence, wherein the vertical plate 502 is vertically arranged on the upper surface of the bottom plate 501, the top plate 503 is vertically arranged on the top of the vertical plate 502, and the top plate 503 is parallel to the bottom plate 501, and the two side blocks 504 are respectively arranged on the upper surface of the top plate 503. The top plate 503 and the two side blocks 504 form the above-mentioned block mechanism.

[0044] Preferably, the bottom plate 501, the vertical plate 502, the top plate 503 and the two side blocks 504 are all made of metal plates, preferably aluminum alloy.

[0045] Exemplarily, the bottom plate 501, the vertical plate 502, the top plate 503 and the two side blocks 504 are integrally formed by machining.

[0046] Optionally, to enhance the overall strength of the supporting connector 5, a row of reinforcing ribs are provided on the left and right sides of the vertical plate 502, one end of the reinforcing rib is connected to the side of the vertical plate 502, and the other end is connected to the upper surface of the bottom plate 501. The reinforcing rib can be any one of a right-angled triangular plate, a right-angled trapezoidal plate or a rectangular plate.

[0047] In the embodiments of the present application, Figure 2 and Figure 3As shown, the auxiliary frame 4 includes a base plate 401 and a support plate 402 connected to each other, and the support plate 402 is vertically arranged on the top surface of the base plate 401. The card slot 403 is arranged at the bottom position of the base plate 401 and penetrates the lower surface of the base plate 401. The cross section of the entire card slot 403 is T-shaped. When the card block mechanism of the support connector 5 is inserted into the card slot 403 of the base plate 401, the two side blocks 504 are respectively placed on the inner bottom walls on the left and right sides of the card slot 403. The height fit between the card block mechanism and the card slot 403 is utilized to ensure the stability between the support connector 5 and the auxiliary frame 4.

[0048] Furthermore, the elastic member 8 is fixed to the top surface of the substrate 401, such as Figure 2 As shown, the lower surface of the photovoltaic module 3 is connected to the elastic member 8, and the elastic member 8 plays the role of supporting and connecting the photovoltaic module 3. The back plate 402 is attached to the side of the photovoltaic module 3 to play the role of edge protection, protecting the side of the photovoltaic module 3 from external collision, scratches and other damages, effectively extending the service life of the photovoltaic module 3.

[0049] Exemplarily, the main body of the auxiliary frame 4 is made of glass.

[0050] In this embodiment, the elastic member 8 is any one of a rubber pad, a rubber spring, and a gas spring, preferably a rubber pad. The upper surface and the lower surface of the rubber pad are respectively bonded to the photovoltaic module 3 and the substrate 401 using double-sided tape. Since the rubber pad has excellent buffering performance and deformation ability, it can provide expansion and deformation avoidance space for the photovoltaic module 3 and the auxiliary frame 4.

[0051] Optionally, a buffer pad, preferably a rubber pad, is installed on the side of the backboard 402 that is in contact with the photovoltaic component 3. The buffer pad is used to prevent the backboard 402 from directly contacting the side of the photovoltaic component 3, so that the auxiliary frame 4 will not damage the side of the photovoltaic component 3 while protecting the side of the photovoltaic component 3.

[0052] It should be explained that, in this embodiment, the length and number of the auxiliary frame 4 and the supporting connector 5 are not specifically limited, and there are multiple possibilities. For example, the auxiliary frame 4 and the supporting connector 5 are one-to-one corresponding, and the lengths of the auxiliary frame 4 and the supporting connector 5 are substantially the same. Alternatively, the length of the supporting connector 5 is greater than the length of the auxiliary frame 4, and multiple auxiliary frames 4 are slidably mounted on each supporting connector 5. Alternatively, the length of the supporting connector 5 is less than the length of the auxiliary frame 4, that is, multiple supporting connectors 5 are slidably connected to one auxiliary frame 4 at the same time.

[0053] In this embodiment, if Figure 2As shown, the limiting mechanism includes a second bolt 7, and at least one first threaded hole is opened on the side of the base plate 401, the first threaded hole is connected to the slot 403, and the axial direction of the first threaded hole is the same as the width direction of the base plate 401. At least one second threaded hole is opened on the side of each side block 504. When the auxiliary frame 4 and the supporting connector 5 are locked, the second bolt 7 is inserted into the first threaded hole and then tightened, and the second bolt 7 is screwed into the second threaded hole of the side block 504. When the locking state is released, it is only necessary to unscrew the second bolt 7.

[0054] It should be noted that the number of the first threaded hole and the second threaded hole is not specifically limited as long as it is reasonable. For example, multiple threads are evenly arranged on the side block 504 of the supporting connector 5 along its length direction, and multiple threads are evenly arranged coaxially on the side surface of the base plate 401 along its length direction.

[0055] As another embodiment, the limiting mechanism includes a first magnetic block 10 and a second magnetic block 11 that are attracted to each other, wherein at least one first mounting groove for mounting the first magnetic block 10 is provided on the inner top wall of the slot 403, and at least one second mounting groove for mounting the second magnetic block 11 is provided on the upper surface of the side block 504. The first magnetic block 10 is embedded and fixed in the first mounting groove on the inner top wall of the slot 403, and the second magnetic block 11 is embedded and fixed in the second mounting groove on the upper surface of the side block 504. The first magnetic block 10 and the second magnetic block 11 are attracted to each other, so as to connect the auxiliary frame 4 and the supporting connector 5.

[0056] Exemplarily, a second magnetic block 11 is installed in the second mounting groove on the upper surface of each side block 504, and at least one group of second mounting grooves is opened on the inner wall of the card slot 403, each group of second mounting grooves includes two second mounting grooves, and the second mounting grooves are respectively close to the left and right sides of the card slot 403.

[0057] It should be understood that there are many possibilities for the number and specific positions of the first magnetic blocks 10 and the second magnetic blocks 11, and no specific limitation is made herein.

[0058] In this way, when connecting the auxiliary frame 4 and the supporting connector 5, first align the slot 403 of the auxiliary frame 4 with one end of the top of the supporting connector 5, and then push the auxiliary frame 4 to make the auxiliary frame 4 slide relative to the supporting connector 5. When the first magnetic block 10 on the auxiliary frame 4 moves to the specified position, the first magnetic block 10 is attracted by the corresponding second magnetic block 11, so that the auxiliary frame 4 and the supporting connector 5 are connected.

[0059] In this embodiment, a first circular hole is formed on the top of the bottom plate 501 of the support connector 5, and a second circular hole is formed on the upper surface of the square steel beam 1. When installing the support connector 5, the first circular hole on the bottom plate 501 of the support connector 5 is aligned with the second circular hole on the square steel beam 1, and then the bottom plate 501 is fixed to the square steel beam 1 using the first bolt 6 and the nut.

[0060] As another specific embodiment, Figure 5 and Figure 6 As shown, the support connector 5 is fixed to the square steel beam 1 using a clamping member 9. Specifically, as Figure 6 As shown, the upper surface of the bottom plate 501 of the supporting connector 5 is provided with an integral hook block 505 , which is an inverted L-shaped plate structure, and a slot is formed between the hook block 505 and the right side surface of the vertical plate 502 .

[0061] Further, such as Figure 7 As shown, the clamping member 9 includes a plug-in block, a third bolt 903 and a locking nut 904. The plug-in block includes a block body 901 and a plug-in block 902 connected to each other. At least one circular hole for the third bolt 903 to pass through is opened on the upper surface of the block body 901. The upper surface of the plug-in block 902 is flush with the upper surface of the block body 901. The thickness of the plug-in block 902 is less than the thickness of the block body 901, so that the lower surface of the plug-in block 902 is lower than the lower surface of the block body 901. The slot on the supporting connector 5 is completely matched with the plug-in block 902. A plurality of holes for the third bolt 903 to pass through are also opened on the square steel beam 1 along its length direction.

[0062] When fixing the supporting connector 5, insert the insert block 902 of the clamping piece 9 into the slot of the supporting connector 5, and then use the third bolt 903 to insert the third bolt 903 upward from the inside of the square steel beam 1. The third bolt 903 passes through the hole on the top surface of the square steel beam 1 and the round hole on the block 901 in turn. Finally, screw the locking nut 904 on the top of the third bolt 903 and tighten it. The locking nut 904 acts on the block 901, so that the insert block 902 presses down the bottom plate 501 tightly to firmly fasten the supporting connector 5 to the square steel beam 1.

[0063] When the supporting connector 5 is subsequently removed or the position of the supporting connector 5 is changed, it is only necessary to loosen the locking nut 904 so that the locking nut 904 no longer presses the insert block 902, which is very convenient to use.

[0064] It should be noted that the square steel beams 1 are evenly arranged on the roof colored steel tiles, and the left and right sides of each photovoltaic module 3 are respectively installed on two square steel beams 1 using the bracket connection assembly, that is, each square steel beam 1 carries at least two photovoltaic modules 3 at the same time.

[0065] The supporting connector 5, the auxiliary frame 4 and the pressing member 9 in this embodiment are all prepared in large quantities in the factory. In addition, before the photovoltaic module 3 leaves the factory, the rubber pad can be fixed to the auxiliary frame 4 using a double-sided tape, and then the auxiliary frame 4 and the photovoltaic module 3 are assembled.

[0066] After reaching the installation site, first install the square steel beam 1 on the roof color steel tile, build a basic support base system, then use the clamping piece 9 to fix the support connector 5 to the square steel beam 1, and then directly assemble the photovoltaic module 3 with the attached frame 4 to the support connector 5. The entire installation process is convenient and fast, greatly saving installation time and improving installation efficiency. It is also very convenient to disassemble the photovoltaic module 3 later.

[0067] After introducing the bracket connection assembly proposed in the embodiment of the present application, a photovoltaic bracket proposed in the embodiment of the present application is introduced below.

[0068] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
