Description

Technical Field

[0001] The utility model relates to the technical field of connecting components, and in particular to a connecting structure for a supporting frame and a photovoltaic module. Background Art

[0002] Solar photovoltaic power generation refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic modules are an important component of solar photovoltaic power generation systems, and photovoltaic modules are connected to photovoltaic support frames.

[0003] The support frame is usually supported by a round tube. The existing connection method between the photovoltaic module and the support frame is usually to connect the photovoltaic module to the support frame through a connection structure such as bolts. The connection structure and the support frame and the connection have a small fit range. Therefore, when the photovoltaic module is affected by natural environment such as wind, the connection between the photovoltaic module and the support frame is very easy to detach. Even when the wind is too strong, the connection point between the photovoltaic module and the support frame may be easily damaged.

[0004] Therefore, how to improve the connection strength between the support frame and the photovoltaic module is an issue that needs to be urgently addressed. Utility Model Content

[0006] The implementation of the utility model is completed by the following technical solutions:

[0007] As a first aspect of the utility model, a connection structure for a support frame comprises:

[0008] The first connecting member comprises a first clamping portion, the first clamping portion is arc-shaped, a first connecting portion is provided on one side of the first clamping portion, and a first locking portion is provided on the other side of the first clamping portion extending in a chord direction away from the first clamping portion;

[0009] The second connecting member comprises a second clamping portion, the second clamping portion is arc-shaped, a second connecting portion is provided on one side of the second clamping portion, and the other side of the second clamping portion extends away from the second clamping portion along a tangent direction of the other side of the second clamping portion to form a second locking portion;

[0010] When in use, the first connecting part is movably connected to the second connecting part, so that the first connecting member and the second connecting member clamp the support frame to be fixed, and the first locking part is locked to the second locking part.

[0014] Optionally, the hook is arc-shaped, and an angle α of the hook is 110°-190°.

[0015] Optionally, the second locking portion includes a first locking segment and a second locking segment, the first locking segment and the second locking segment form an L-shape, and the first locking segment and the second locking segment are each provided with at least one first connecting hole.

[0016] Optionally, the first locking portion includes a third locking segment and a fourth locking segment, and the third locking segment and the fourth locking segment are both provided with a second connecting hole, and the second connecting hole corresponds to the first connecting hole one by one.

[0017] Optionally, the connection structure for the support frame further includes a support portion, wherein the support portion is disposed between the first locking portion and the second locking portion, and the support portion is connected to an end of the second locking portion close to the first connecting member.

[0019] Optionally, a weight-reducing groove is provided on the support portion.

[0020] As a second aspect of the present utility model, a photovoltaic module includes: a photovoltaic panel, a frame surrounding the photovoltaic panel, and a support frame connected to the back of the photovoltaic panel;

[0021] It also includes the connection structure for the support frame as described above, and the support frame is connected to the surface of the frame on the same side as the back side of the photovoltaic panel through the connection structure.

[0022] The advantages of the utility model are: improving the stability of the connection between the support frame and the photovoltaic module, improving the convenience of using the connection structure, and at the same time increasing the stability of adjacent frames in the photovoltaic module when connecting with the photovoltaic module.

While the locking segment is connected to the frame, the two adjacent frames are connected, thereby increasing the stability of the connection between adjacent frames in the photovoltaic module.

[0039] As a first aspect of this embodiment, Figures 1 to 4 As shown, a connection structure for a support frame includes:

[0040] The first connecting member 1 comprises a first clamping portion 11, the first clamping portion 11 is arc-shaped, a first connecting portion 12 is provided on one side of the first clamping portion 11, and a first locking portion 13 is provided on the other side of the first clamping portion 11 extending in a direction away from the first clamping portion 11 along the chord of the arc;

[0041] The second connecting member 2 comprises a second clamping portion 21, the second clamping portion 21 is arc-shaped, a second connecting portion 22 is provided on one side of the second clamping portion 21, and the other side of the second clamping portion 21 extends along the tangent direction of the other side of the second clamping portion 21 in a direction away from the second clamping portion 21 to form a second locking portion 23;

[0042] When in use, the first connecting portion 12 is movably connected to the second connecting portion 22 , so that the first connecting member 1 and the second connecting member 2 clamp the support frame to be fixed, and the first locking portion 13 is locked to the second locking portion 23 .

[0043] It should be noted that, in this embodiment, the implementation methods of the movable connection between the second connection part 22 and the first connection part 12 include but are not limited to the following:

[0044] First, the first connection part 12 and the second connection part 22 are hingedly connected via a hinge axis; the hinge axis facilitates the opening and closing of the first connection part 12 and the second connection part 22, and facilitates clamping of the connection of the support frame.

[0045] Second, one of the first connection part 12 or the second connection part 22 is a slider, and the other is a slide groove adapted to the slider, and the first connection part 12 and the second connection part 22 form a sliding connection; in this implementation, the first connection part 12 and the second connection part 22 are designed separately, the structure is simpler, and the production cost is effectively reduced.

[0046] When this implementation method is used, the first connecting part 12 is inserted from the end of the second connecting part 22 to the corresponding position, so that the first connecting member 1 and one side of the second connecting member 2 form a sliding connection to clamp the support frame; therefore, this implementation method requires a certain amount of space along the axial direction of the arc of the first clamping part 11, and is suitable for the situation where the radial space at the connection of the support frame is insufficient.

[0047] Third, one of the first connecting portion 12 or the second connecting portion 22 is a hook, and the other is a hook groove adapted to the hook, and the second connecting member 2 rotates relative to the first connecting portion 12 of the first connecting member 1 through the second connecting portion 22; Figures 1 to 4 As shown, the first connecting part 12 is a hook, the second connecting part 22 is a hook groove, and the first connecting member 1 rotates relative to the hook groove of the second connecting member 2 through the hook; in this implementation, the first connecting part 12 and the second connecting part 22 are designed separately, the structure is simpler, and the production cost is effectively reduced.

[0048] When this implementation method is used, the first connection part 12 of the first connection member 1 is hooked with the second connection part 22 of the second connection member 2, and the first connection member 1 is rotated relative to the second connection member 2 to clamp the support frame; this implementation method requires a certain space along the radial direction of the arc of the first clamping part 11, and is suitable for the situation where the axial space at the connection of the support frame is insufficient.

[0049] Furthermore, in the third implementation, as Figure 3 As shown, when the first connection portion 12 is a hook, the hook of the first connection portion 12 is arc-shaped, and the angle α of the hook is 110°-190°.

[0050] It should be noted that when using the connection structure of this embodiment, the outward end of the second locking portion 23 of the second connecting member 2 is fitted with the installation position, the support frame is clamped by the first connecting member 1 and the second connecting member 2, and a connecting member, such as a bolt, is used to pass through the first locking portion 13 and the second locking portion 23 in sequence and connect to the installation position, so that the first locking portion 13 is locked to the second locking portion 23.

[0051] Further, in this embodiment, when the connection structure of this embodiment is connected to the frame of the photovoltaic panel, especially when the connection structure is connected to two adjacent frames of the photovoltaic panel, the following design is made to more stably install the connection structure:

[0052] like Figures 1 to 4As shown, the second locking portion 23 includes a first locking segment 231 and a second locking segment 232, the first locking segment 231 and the second locking segment 232 are L-shaped, and the first locking segment 231 and the second locking segment 232 are each provided with at least one first connecting hole 24; further, the first locking portion 13 includes a third locking segment 131 and a fourth locking segment 132, and the third locking segment 131 and the fourth locking segment 132 are provided with a second connecting hole 14, and the second connecting hole 14 corresponds one-to-one to the first connecting hole 24.

[0053] It should be noted that when using the connection structure of this embodiment, the first locking section 231 and the second locking section 232 are respectively fitted with adjacent frames, and bolts are used to pass through the second connection hole 14 and the first connection hole 24 in sequence, and the bolts are connected to the frames. In this process, the first locking portion 13 is also locked to the second locking portion 23, and while clamping the support frame, the connection between the adjacent frames is reinforced, making the connection between the adjacent frames of the photovoltaic module more stable.

[0054] It should be noted that, in this embodiment, in order to prevent excessive locking, Figures 1 to 4 As shown, the connection structure further includes a support portion 25 , which is disposed between the first locking portion 13 and the second locking portion 23 , and is connected to an end of the second locking portion 23 close to the first connecting member 1 .

[0055] Furthermore, in order to improve the stability of the connection between the connecting structure and the support frame and increase the contact area between the connecting structure and the support frame, the end of the supporting portion 25 close to the second clamping portion 21 is provided with an arc surface that is concentric and has the same radius as the arc-shaped second clamping portion 21, so that the supporting portion 25 abuts against the support frame to increase the contact area between the connecting structure and the support frame.

[0056] Furthermore, in this embodiment, a weight-reducing groove 251 is provided on the support portion 25 to reduce the deadweight of the connection structure. Without affecting the function of the support portion 25, the weight-reducing groove 251 can be a depression or groove provided on the support portion 25, or can be a through groove provided on the support portion 25 along the axial direction of the second connecting member 2 or perpendicular to the axial direction of the second connecting member 2.

[0057] As a second aspect of this embodiment, a photovoltaic module includes: a photovoltaic panel, a frame surrounding the photovoltaic panel, and a support frame connected to the back of the photovoltaic panel;

[0058] It also includes the connection structure for the support frame as described above, and the support frame is connected to the surface of the frame on the same side as the back side of the photovoltaic panel through the connection structure.
