Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket design technology, specifically to a photovoltaic bracket and a photovoltaic system. Background Technology

[0002] Wall-mounted photovoltaic (PV) brackets have a wide range of applications and a large market presence in various residential scenarios. Furthermore, building a PV power station on a wall results in less shading and better light absorption, maximizing the utilization of clean photovoltaic energy while saving installation space.

[0003] In related technologies, the frame of a photovoltaic module is connected to the photovoltaic support structure using bolts. However, during the connection process, when the bolts are tightened, the connecting parts of the photovoltaic support structure may rotate, resulting in a loose fit between the connecting parts and the frame of the photovoltaic module, posing a risk of the photovoltaic module detaching or falling. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic bracket and a photovoltaic system to solve the problem of unreliable adhesion between the connector and the frame of the photovoltaic module, which poses a safety hazard.

[0005] In a first aspect, this utility model provides a photovoltaic bracket, comprising: a wall-mounting assembly, a connector, and a telescopic assembly; at least two wall-mounting assemblies are provided, each adapted to be connected to a wall; at least two connectors are provided, with each wall-mounting assembly and connector corresponding to one of them, each connector comprising a platform portion, a first connecting portion, and a protruding structure, the platform portion being adapted to be connected to a photovoltaic frame, the first connecting portion being connected to the platform portion, and the protruding structure being connected to the platform portion and disposed on the side of the platform portion away from the first connecting portion, the protruding structure being adapted to abut against the photovoltaic frame; at least one telescopic assembly is provided, the telescopic assembly being disposed between the wall-mounting assembly and the connector, and connected to both the wall-mounting assembly and the connector.

[0006] Beneficial effects: By adding a protruding structure to the connector, the protruding structure and the platform part abut against the photovoltaic frame on both sides, making the contact area between the connector and the photovoltaic frame larger. At the same time, because the connector and the photovoltaic frame are in contact at multiple angles, the rotation of the connector is effectively restricted when tightening the bolts, thereby ensuring the connection stability between the connector and the photovoltaic frame and preventing the photovoltaic module from falling off.

[0007] In one alternative embodiment, the wall-mounting assembly includes a base and a hanger, the base being adapted to connect to a wall, the hanger having a groove, a portion of the base being embedded in the groove and connected to the hanger, and the hanger being connected to the connector or the telescopic assembly.

[0008] Beneficial effects: The connection method of embedding part of the base into the groove of the hanging bracket increases the contact area and friction between the two, effectively preventing the wall-mounted components from loosening due to external forces such as wind and vibration during long-term use, and ensuring the stability of the connection between the photovoltaic bracket and the wall.

[0009] In one optional embodiment, the base includes a main body and a protrusion, the main body being connected to the protrusion and adapted to be connected to a wall, the protrusion being embedded in the groove, the protrusion having a first mounting hole, the hanger having a second mounting hole communicating with the groove, the second mounting hole corresponding to the first mounting hole, and the wall-mounted assembly further including a first fastener, the first fastener being sequentially inserted through the second mounting hole and the first mounting hole.

[0010] Beneficial effect: By passing the first fastener through the corresponding first and second mounting holes, the protrusion of the base and the groove of the hanger are tightly fixed together, forming a reliable mechanical connection.

[0011] In one alternative embodiment, the base further includes an extension that connects to the protrusion and abuts against the hanging element.

[0012] Beneficial effects: The extension part abuts against the hanging part, which is equivalent to adding an extra support point at the connection between the base and the hanging part, improving the overall structural stability and load-bearing capacity of the wall-mounted component; at the same time, by setting the extension part, the hanging part can be hung first and then tightened during installation, which greatly reduces the difficulty of operation.

[0013] In one alternative embodiment, the second mounting hole is a waist-shaped hole.

[0014] Beneficial effects: The second mounting hole is a waist-shaped hole, which can compensate for the installation position deviation between the base and the hanging part. Accurate installation can be achieved by adjusting the position of the first fastener in the waist-shaped hole, thereby improving the overall applicability of the photovoltaic bracket.

[0015] In one alternative embodiment, the hanger includes a mounting portion and a second connecting portion, the mounting portion being connected to the second connecting portion, the mounting portion having the groove, and the second connecting portion being connected to the connector or the telescopic assembly.

[0016] In one optional embodiment, there are two first connecting parts, which are spaced apart and abut against the two ends of the second connecting part respectively. The first connecting part is provided with a third mounting hole, and the second connecting part is provided with a fourth mounting hole. The photovoltaic bracket also includes a second fastener, which is sequentially inserted through the third mounting hole and the fourth mounting hole at one end and the third mounting hole at the other end.

[0017] Beneficial effects: The two spaced-apart first connecting parts abut against each other at both ends of the second connecting parts and are fixed by the second fasteners passing through the mounting holes, forming a stable connection structure and ensuring the overall stability of the photovoltaic bracket.

[0018] In one optional embodiment, the telescopic assembly includes a diagonal brace outer sleeve, a diagonal brace inner sleeve, and a fixing member. One of the diagonal brace outer sleeve and the diagonal brace inner sleeve is connected to the wall-mounting assembly, and the other of the diagonal brace outer sleeve and the diagonal brace inner sleeve is connected to the connecting member. The diagonal brace outer sleeve has a cavity, and a portion of the diagonal brace inner sleeve is embedded in the cavity. The diagonal brace outer sleeve has a first fixing hole, and the diagonal brace inner sleeve has a plurality of second fixing holes. The fixing member passes through the first fixing hole and any one of the second fixing holes in sequence.

[0019] Beneficial effects: By selecting different positions of the second fixing hole to match the first fixing hole and using fasteners for fixing, the depth of the inner sleeve of the diagonal brace embedded in the outer sleeve of the diagonal brace can be changed, thereby adjusting the overall length of the telescopic component and thus changing the installation angle of the photovoltaic frame.

[0020] In one optional embodiment, the ends of the outer sleeve and the inner sleeve of the diagonal brace are rounded ends.

[0021] Beneficial effect: By using the arc-shaped end structure design, interference between the end and the wall-mounted component or connector can be avoided when adjusting the connection angle between the outer and inner sleeves of the diagonal brace and the wall-mounted component or connector.

[0022] Secondly, this utility model provides a photovoltaic system, including the aforementioned photovoltaic bracket. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0034] According to an embodiment of the present invention, in a first aspect, a photovoltaic bracket is provided, comprising: a wall-mounted component 10, a connector 20, and a telescopic component 30; at least two wall-mounted components 10 are provided, and the wall-mounted components 10 are adapted to be connected to a wall; at least two connectors 20 are provided, and the wall-mounted components 10 and connectors 20 are provided in a one-to-one correspondence, the connector 20 includes a platform portion 21, a first connecting portion 22, and a protruding structure 23, the platform portion 21 is adapted to be connected to a photovoltaic frame 40, the first connecting portion 22 is connected to the platform portion 21, the protruding structure 23 is connected to the platform portion 21 and is disposed on the side of the platform portion 21 away from the first connecting portion 22, and the protruding structure 23 is adapted to abut against the photovoltaic frame 40; at least one telescopic component 30 is provided, the telescopic component 30 is disposed between the wall-mounted component 10 and the connector 20, and is connected to the wall-mounted component 10 and the connector 20.

[0035] By using the photovoltaic bracket of this embodiment, the additional protrusion structure 23 provided on the connector 20 abuts against the photovoltaic frame 40 on both sides using the protrusion structure 23 and the platform part 21, so that the contact area between the connector 20 and the photovoltaic frame 40 is larger. At the same time, since the connector 20 and the photovoltaic frame 40 are in contact at multiple angles, the rotation of the connector 20 is effectively restricted when tightening the bolts, thereby ensuring the connection stability between the connector 20 and the photovoltaic frame 40 and preventing the photovoltaic module from falling off.

[0036] It should be noted that in the relevant technology, during the connection process between the photovoltaic frame 40 and the photovoltaic bracket, when the rotating bolt is tightened, it may cause the connecting piece 20 of the photovoltaic bracket to rotate, which may result in the connecting piece 20 not being firmly attached to the photovoltaic module frame, posing a risk of the photovoltaic module coming off or falling.

[0037] Therefore, in this embodiment, by setting the protruding structure 23, the protruding structure 23 is used to limit the contact with the photovoltaic frame 40 at another angle, thereby restricting the rotation of the connector 20 when tightening the bolt, thus ensuring the connection stability between the connector 20 and the photovoltaic frame 40.

[0038] Specifically, such as Figure 3 As shown, there are two protruding structures 23, which are spaced apart.

[0039] It should be noted that in other alternative embodiments, multiple protrusions 23 may be provided at intervals.

[0040] Specifically, in this embodiment, such as Figure 1 As shown, there are four wall-mounted components 10 and four connectors 20, and two telescopic components 30. Two of the wall-mounted component 10 brackets are directly connected to the connectors 20, and the other two wall-mounted components 10 are connected to the connectors 20 through the telescopic components 30.

[0041] Furthermore, the two telescopic components 30 are connected to the lower frame of the photovoltaic frame 40 via the connector 20, and the angle between the photovoltaic frame 40 and the wall is adjusted by the synchronous extension and retraction of the two telescopic components 30.

[0042] It should be noted that in other alternative embodiments, the wall-mounted component 10, the connector 20, and the telescopic component 30 can be adjusted according to the actual situation. For example, only two wall-mounted components 10 and two connectors 20 are provided, and only one telescopic component 30 is provided. The two connectors 20 are respectively connected to the upper and lower edges of the photovoltaic frame 40. Alternatively, the number of telescopic components 30 can be equal to the number of wall-mounted components 10, that is, the telescopic components 30 are respectively connected to the upper and lower edges of the photovoltaic frame 40 through the connectors 20.

[0043] In one embodiment, such as Figure 2 As shown, the wall-mounted assembly 10 includes a base 11 and a hanger 12. The base 11 is adapted to be connected to a wall, and the hanger 12 has a groove 121. A portion of the base 11 is embedded in the groove 121 and connected to the hanger 12, as shown. Figure 1 As shown, the hanger 12 is connected to the connector 20 or the telescopic assembly 30.

[0044] Specifically, such as Figure 1 As shown, two of the hanging parts 12 are connected to the connector 20, and two of the hanging parts 12 are connected to the telescopic assembly 30.

[0045] It is worth noting that the connection method in which some of the bases 11 are embedded in the grooves 121 of the hanging parts 12 increases the contact area and friction between the two, effectively preventing the wall-mounted components 10 from loosening due to external forces such as wind and vibration during long-term use, thus ensuring the stability of the connection between the photovoltaic bracket and the wall.

[0046] Furthermore, such as Figure 4 As shown, the base 11 includes a main body 111 and a protrusion 112. The main body 111 is connected to the protrusion 112. The main body 111 is adapted to be connected to the wall. The protrusion 112 is embedded in the groove 121. A first mounting hole 1121 is provided on the protrusion 112. The hanger 12 is provided with a second mounting hole 122. The second mounting hole 122 communicates with the groove 121. The second mounting hole 122 is correspondingly provided with the first mounting hole 1121. The wall-mounted assembly 10 also includes a first fastener 13. The first fastener 13 is sequentially inserted through the second mounting hole 122 and the first mounting hole 1121.

[0047] It is worth noting that by passing the first fastener 13 through the corresponding first mounting hole 1121 and second mounting hole 122, the protrusion 112 of the base 11 and the groove 121 of the hanger 12 are tightly fixed together, forming a reliable mechanical connection.

[0048] It should be noted that the main body 111 and the protrusion 112 can be connected separately or integrally formed.

[0049] Specifically, the first fastener 13 is a bolt, and the protrusion 112 is detachably connected to the hanger 12 by the bolt.

[0050] Furthermore, such as Figure 5 As shown, the hanger 12 includes a hanging part 123 and a second connecting part 124. The hanging part 123 is connected to the second connecting part 124. The hanging part 123 has a groove 121. The second connecting part 124 is connected to the connector 20 or the telescopic assembly 30.

[0051] Specifically, two of the second connecting parts 124 are connected to the connector 20, and two of the second connecting parts 124 are connected to the telescopic assembly 30.

[0052] Furthermore, such as Figure 4 As shown, the base 11 also includes an extension 113, which is connected to the protrusion 112 and abuts against the hanging piece 12.

[0053] Specifically, such as Figure 4 As shown, the extension 113 is formed by extending outward from a portion of the structure of the protrusion 112.

[0054] It is worth noting that the extension 113 abuts against the hanging part 12, which is equivalent to adding an extra support point at the connection between the base 11 and the hanging part 12, thereby improving the overall structural stability and load-bearing capacity of the wall-mounted assembly 10. At the same time, by setting the extension 113, the hanging part 12 can be hung first and then tightened during installation, which greatly reduces the difficulty of operation.

[0055] Furthermore, such as Figure 5 As shown, the second mounting hole 122 is a slotted hole.

[0056] It is worth noting that the second mounting hole 122 is an oblong hole, which can compensate for the installation position deviation between the base 11 and the hanger 12. Accurate installation can be achieved by adjusting the position of the first fastener 13 in the oblong hole, thereby improving the overall applicability of the photovoltaic bracket.

[0057] In one embodiment, such as Figure 3 As shown, there are two first connecting parts 22, which are spaced apart and abut against both ends of the second connecting part 124 respectively. The first connecting part 22 is provided with a third mounting hole 221, and the second connecting part 124 is provided with a fourth mounting hole 1241. The photovoltaic bracket also includes a second fastener, which is sequentially inserted through the third mounting hole 221 and the fourth mounting hole 1241 at one end and the third mounting hole 221 at the other end.

[0058] Specifically, the second fastener includes a bolt and a nut. The bolt passes through the third mounting hole 221 and the fourth mounting hole 1241 at one end and the third mounting hole 221 at the other end in sequence, and is fastened by the nut.

[0059] It is worth noting that the two spaced-apart first connecting parts 22 and second connecting parts 124 abut against each other at both ends and are fixed by the second fasteners through the mounting holes, forming a stable connection structure and ensuring the overall stability of the photovoltaic bracket.

[0060] In one embodiment, such as Figure 1 and Figure 6 As shown, the telescopic assembly 30 includes a diagonal brace outer sleeve 31, a diagonal brace inner sleeve 32, and a fixing member 33. One of the diagonal brace outer sleeve 31 and the diagonal brace inner sleeve 32 is connected to the wall-mounted assembly 10, and the other of the diagonal brace outer sleeve 31 and the diagonal brace inner sleeve 32 is connected to the connector 20. The diagonal brace outer sleeve 31 has a cavity, and part of the diagonal brace inner sleeve 32 is embedded in the cavity. The diagonal brace outer sleeve 31 has a first fixing hole 311, and the diagonal brace inner sleeve 32 has a plurality of second fixing holes 321. The fixing member 33 passes through the first fixing hole 311 and any one of the second fixing holes 321 in sequence.

[0061] Specifically, the inner sleeve 32 of the diagonal brace has three second fixing holes 321.

[0062] Of course, in other alternative embodiments, the number of second fixing holes 321 can be adjusted according to the actual situation.

[0063] Of course, in other alternative embodiments, only one second fixing hole can be opened on the inner sleeve 32 of the diagonal brace, and multiple first fixing holes 311 can be opened on the outer sleeve 31 of the diagonal brace.

[0064] Specifically, fastener 33 is a pin.

[0065] It is worth noting that by selecting different positions of the second fixing hole 321 to cooperate with the first fixing hole 311 and using the fastener 33 for fixing, the depth of the inner sleeve 32 of the diagonal brace embedded in the outer sleeve 31 of the diagonal brace can be changed, thereby adjusting the overall length of the telescopic component 30 and thus changing the installation angle of the photovoltaic frame 40.

[0066] It should be noted that in other alternative embodiments, the telescopic component 30 can also be a telescopic hydraulic cylinder, pneumatic cylinder, or other structure.

[0067] Furthermore, as shown in 6, the ends of the outer sleeve 31 and the inner sleeve 32 of the diagonal brace are rounded ends.

[0068] It should be noted that when the ends of the diagonal brace outer sleeve 31 and the diagonal brace inner sleeve 32 are square ends, when adjusting the connection angle between the diagonal brace outer sleeve 31 and the diagonal brace inner sleeve 32 and the wall-mounted component 10 or the connector 20, the pointed end of the square end may scratch and interfere with the wall-mounted component 10 or the connector 20.

[0069] It is worth noting that, through the end structure design of the arc end, interference between the end and the wall-mounted component 10 or the connector 20 can be avoided when adjusting the connection angle between the outer sleeve 31 and the inner sleeve 32 of the diagonal brace and the wall-mounted component 10 or the connector 20.

[0070] According to an embodiment of the present invention, in a second aspect, a photovoltaic system is provided, including the photovoltaic support described above.

[0071] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
