[0036] In related technologies, snow-blocking clamps are installed on the frames of photovoltaic modules to reduce personal injury and property damage, thereby reducing the volume and weight of large-volume and heavy snowfalls. However, the snow-blocking clamps are one-piece structures; such structures can only accommodate frames of one height. In actual production, the height of the frame varies, therefore, existing technologies require different snow-blocking clamps to adapt to frames of different heights, which involves the development of molds and other components, leading to a significant increase in costs. Therefore, the embodiments of this application aim to solve the technical problem of poor adaptability of existing snow-blocking clamps by providing a highly versatile snow-blocking clamp that can accommodate frames of different heights.
[0037] Reference Figure 1 and Figure 2 As shown, this application embodiment provides a snow-blocking clamp 1000 for mounting on the frame 500 of a photovoltaic module 10. It includes:
[0038] The body 100 is provided with a plurality of first connecting portions 110 spaced apart along the height direction;
[0039] A first component 200 is provided with a hook 210 for clamping the frame 500; a second connecting part 220 is provided at one end of the first component 200 away from the hook 210, and the second connecting part 220 can cooperate with the plurality of first connecting parts 110 so that the first component 200 can be placed at different height positions of the body 100.
[0040] In the technical solution of this application embodiment, a plurality of first connecting portions 110 arranged along the height direction are provided on the body 100 of the snow-blocking clamp 1000; a second connecting portion 220 adapted to the first connecting portion 110 is provided on the first component 200 of the snow-blocking clamp 1000; then, when the snow-blocking clamp 1000 is placed on the frame 500, the second connecting portion 220 can be installed on the first connecting portion 110 adapted to the height of the frame 500 according to the height of the frame 500, that is, the first component 200 can be placed at different height positions; during installation, the hook 210 of the first component 200 is hooked onto the inner side of the frame 500, and then the snow-blocking clamp 1000 is placed on the frame 500. Therefore, the technical solution of this application embodiment separates the first component 200 from the body 100, and the first component 200 can be set at different height positions of the body 100 to adapt to the frame 500 of different heights, thereby improving the adaptability of the snow-blocking clamp 1000 and making the snow-blocking clamp 1000 universal.
[0041] In some embodiments, the first connecting portion 110 can be one of a threaded hole and a threaded post, and the second connecting portion 220 can be the other of a threaded hole and a threaded post, meaning that the body 100 and the first component 200 can be connected by threads. In other embodiments, the first connecting portion 110 can be a through hole, and the second connecting portion 220 can be a threaded post. The second connecting portion 220 passes through the through hole, allowing the threaded post to pass through to the other side of the body 100, and the threaded post is fixed by bolts, so that the first component 200 is fixed to the body 100.
[0042] As an optional implementation of the above embodiments, such as Figure 2 He Ru Figure 3As shown, the main body 100 has a snow-blocking section 120 that extends along the height direction. The snow-blocking section 120 can be heightened to block large snow accumulations into smaller ones. The first connecting portion 110 includes one of a slot and a locking head disposed on the snow-blocking section 120; the second connecting portion 220 includes the other of a slot and a locking head; the slot and the locking head are adapted to each other. In an embodiment, the locking head is installed into the slot, and the component is disposed on the snow-blocking section 120. Further, the slots or locking heads are distributed along the height direction, and the implementer can then place the first component 200 in the slot or on the locking head that matches the height of the matching frame 500 according to the actual situation.
[0043] like Figure 3 As shown, the first connecting portion 110 includes a first clamping edge 111 and a second clamping edge 112 disposed opposite to each other. Both the first clamping edge 111 and the second clamping edge 112 extend from the snow-blocking section 120 toward the frame 500 and form a first slot S1. The first slot S1 has a clearance opening S2, which is adapted to the first component 200. The second connecting portion 220 is a first locking head adapted to the first slot S1. In an embodiment, the first locking head is installed into the first slot S1, and the first clamping edge 111 and the second clamping edge 112 are used to hold the first locking head on the snow-blocking section 120. The first component 200 extends out of the first slot S1 through the clearance opening S2. Further, the first slot S1 is distributed along the height direction, allowing the implementer to set the first locking head of the first component 200 on a first locking head that matches the height of the frame 500 according to the actual situation.
[0044] Alternatively, in some other embodiments, the first connecting portion 110 includes a second clamping head disposed on the snow-blocking section 120; the second connecting portion 220 includes a third clamping edge and a fourth clamping edge disposed opposite to each other, the third clamping edge and the fourth clamping edge both extending from the first member 200 away from the hook body 210 and forming a second clamping groove; the second clamping groove is adapted to the second clamping head. That is, in the embodiments, the second clamping groove of the first member 200 is engaged with the second clamping head on the snow-blocking section 120, and the first member 200 is held on the snow-blocking section 120 by clamping the second clamping head with the third clamping edge and the fourth clamping edge. Further, the second clamping head is distributed along the height direction, and the implementer sets the second clamping groove of the first member 200 on the second clamping head matching the height of the frame 500 according to the actual situation.
[0045] As an optional implementation of the above embodiments, the first clamping edge 111 and the second clamping edge 112 are close to each other at the end away from the snow-blocking section 120. In this embodiment, the first clamping edge 111 and the second clamping edge 112 being close to each other can constrain the first component 200 in the first horizontal direction, reducing the risk of the first component 200 falling off and improving the stability of the structure. In other embodiments, the third clamping edge and the fourth clamping edge are close to each other at the end away from the hook body 210, which can constrain the first component 200 in the horizontal direction, reducing the risk of the first component 200 falling off and improving the stability of the structure.
[0046] As an optional implementation of the above embodiments, the first clamping edge 111 and the second clamping edge 112 extend horizontally to form a horizontally extending first slot S1, and at least one end of the first slot S1 in the horizontal direction forms a first insertion port. In this embodiment, the first clip can be inserted into the first slot S1 through the first insertion port in the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to the height direction and perpendicular to each other; the surface defined by the first horizontal direction and the second horizontal direction is generally parallel to the light-receiving surface (front) of the photovoltaic module 10. The light-receiving surface refers to the main surface that directly faces the sun and is used to receive sunlight.
[0047] The third and fourth clamping edges extend horizontally to form a horizontally extending second slot, and at least one end of the second slot in the horizontal direction forms a second insertion port. In an embodiment, the second clip can be inserted into the second slot along the second horizontal direction through the second insertion port. The first and second horizontal directions are perpendicular to the height direction and are perpendicular to each other; the surface defined by the first and second horizontal directions is generally parallel to the light-receiving surface (front) of the photovoltaic module 10. The light-receiving surface refers to the main surface that directly faces the sun and is used to receive sunlight.
[0048] Combination Figures 1 to 4 As shown, in an optional embodiment of the above example, the body 100 has a horizontal segment 130; the horizontal segment 130 is connected to the first component 200 via a connector 400. To improve the stability of the overall structure, in this embodiment, after the second connecting portion 220 of the first component 200 is installed to the first connecting portion 110, the first component 200 is then fixed to the horizontal segment 130 of the body 100 via the connector 400. In this embodiment, the horizontal segment 130 and the snow-blocking segment 120 are arranged intersecting each other, and are usually set to be perpendicular to each other. The connector 400 can be a threaded component or a part including a threaded structure.
[0049] For example, in some embodiments, the connector 400 includes a bolt and a slider nut. A groove adapted to the slider nut is provided on the horizontal segment 130. The slider nut is pre-assembled into the groove, and the first component 200 is fixedly connected to the slider nut and the body segment 100 by bolts, realizing a detachable connection and fixing the first component 200 to the body 100.
[0050] In some embodiments, the horizontal segment 130 is provided with a first connecting hole, the axis of which is parallel to the height direction; the first component 200 is provided with a second connecting hole. The snow-blocking clamp 1000 further includes a connector 400, which is used to connect the first connecting hole and the second connecting hole so that the first component 200 is disposed on the body 100. In this embodiment, that is, after the connector 400 connects the body 100 and the first component 200, it achieves constraint on the first component 200 in the height direction, thereby improving the stability of the overall structure. In this embodiment, the connector 400 may include a threaded component. The threaded component is fastened to the first connecting hole and the second connecting hole, further fixing the first component 200 to the body 100, thereby improving the overall stability of the snow-blocking clamp 1000.
[0051] In this embodiment, the area where the first connecting hole is located is thickened, which can increase the structural strength of the body 100, and also enable rapid installation and improve construction convenience.
[0052] As an optional implementation of the above embodiments, such as Figure 4 As shown, the hook 210 extends outward at an angle from the end of the first component 200 away from the second connecting portion 220, and the extension direction of the hook 210 forms an acute angle α with the height direction. In some embodiments, the end of the first component 200 is provided with a hook 210 that is inclined outward at 17°. During installation, the hook 210 can hook onto the component frame 500A, maximizing the clamping effect of the clamp and solving the problem of the current snow-blocking clamp 1000 being easy to fall off.
[0053] In the embodiment, the angle between the extension direction and the height direction of the hook 210 is typically set according to the specific shape of side A. The purpose of this angle is to increase the clamping force of the clamp so that the snow-blocking clamp 1000 can stably hook onto the frame 500.
[0054] As an optional implementation of the above embodiments, such as Figure 4 As shown, the first component 200 is provided with anti-slip teeth 230. For example... Figure 2 and Figure 4As shown, when the snow-blocking clamp 1000 is fixed to the frame 500, the anti-slip teeth 230 abut against the frame 500. In this embodiment, anti-slip teeth 230 are provided on the snow-blocking clamp 1000 and are used to abut against the frame 500 to increase friction, thereby improving the stability of the snow-blocking clamp 1000 and effectively reducing the risk of the snow-blocking clamp 1000 falling off. The part of the first component 200 that contacts the frame 500 is provided with continuous anti-slip teeth 230, the size of which is set to 1x0.5mm, that is, tooth width 1mm and tooth height 0.5mm. The specific size of the anti-slip teeth 230 can be set according to specific circumstances and is not specifically limited.
[0055] In some embodiments, the anti-slip teeth 230 are formed on the surface of the first member 200 and may be serrated or wavy.
[0056] like Figure 2 As shown in the illustration, this application also proposes a photovoltaic module 10, including a frame 500 and a snow-blocking clamp 1000. The snow-blocking clamp 1000 adopts some or all of the technical solutions in the foregoing embodiments, thus the photovoltaic module 10 has some or all of the technical advantages of the foregoing embodiments.
[0057] like Figure 1 and Figure 5 As shown, the frame 500 includes side A (upper part) and side C (lower part). In some embodiments, the first member 200 hooks onto side A; the snow-blocking assembly also has a second member 300, which is spaced apart from the first member 200 in the height direction, and hooks onto side C. The second member 300 may be integrally mounted on the body 100. Figure 1 It can also be detachably connected (e.g., via threaded connection) to the body 100. Figure 5 In some other embodiments, the first member 200 may also be used to hook side C, while the second member 300 hooks side A.
[0058] The border includes side A, side B, and side C. Sides A and C are located at opposite ends of side B in a first direction. Sides A, B, and C are common terms used by those skilled in the art. Sides A, B, and C are different parts of the border named according to the size, shape, and position of the component, and each has a different function:
[0059] The A-side refers to the top edge of the frame, which is the edge of the top of the photovoltaic panel visible from a top-down view. The basic function of the A-side is to ensure that the edge of the solar panel is protected from damage caused by external forces, and it is also an important component for fixing the position of the photovoltaic panel during assembly.
[0060] The B-sides refer to the two sides of the frame. Their main function is to support and fix the position of the photovoltaic panels, constrain the ends of the panels, and ensure that the panels are arranged evenly and neatly. The B-sides also provide some protection against damage to the edges.
[0061] The C-edge refers to the lower edge of the frame, which is typically connected to the bracket or frame in the mounting system. The presence of the C-edge helps maintain the stability and uprightness of the component, and also facilitates connection with other structural components.
[0062] As an optional implementation of the above embodiments, multiple snow-blocking clamps 1000 are provided, and the multiple snow-blocking clamps 1000 are spaced apart on the frame 500. In this embodiment, the multiple snow-blocking clamps 1000 spaced apart on the frame 500 can break large snow accumulations into multiple smaller snow accumulations, thereby reducing the volume and weight of falling snow. In some embodiments, the photovoltaic module 10 is quadrilateral, that is, it has four frames 500. Multiple snow-blocking clamps 1000 can be provided on each frame 500. The spacing between the snow-blocking clamps 1000 is not specifically limited, that is, the number is not specifically limited, and can be specifically set by the implementer according to the situation.
[0063] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
