Description

Technical Field

[0001] The embodiments in this specification relate to the field of photovoltaic power generation technology, and in particular to a blocking device and a photovoltaic system. Background Technology

[0002] In certain applications, photovoltaic modules are prone to accumulating snow. When the snow on the photovoltaic modules slides off, it can easily damage houses or other objects below, posing a certain safety risk.

[0003] In related technologies, a blocking device is typically installed on the photovoltaic frame of a photovoltaic module to prevent snow accumulation on the module from sliding off. However, this blocking device can only be installed on a photovoltaic frame of a certain shape. When the shape of the photovoltaic frame changes, the blocking device cannot be reliably and stably fixed to the frame, greatly reducing its adaptability and installation stability.

[0004] Therefore, there is an urgent need for a blocking device and a photovoltaic system to solve the above problems. Utility Model Content

[0005] The purpose of this specification is to provide a blocking device and a photovoltaic system to block snow accumulation on photovoltaic modules, thereby avoiding the safety risks caused by snow sliding off the photovoltaic modules. Furthermore, the blocking device has high adaptability and good installation stability.

[0006] To achieve this objective, the embodiments in this specification adopt the following technical solutions:

[0007] A blocking device, comprising:

[0008] A blocking member, the blocking member including a connecting abutment portion and a blocking portion, the end of the blocking portion including a first engagement structure, the first engagement structure abutting against the end face of the photovoltaic frame;

[0009] The tray includes a first fitting part and a second fitting part connected to each other. The first fitting part abuts against the photovoltaic frame, and the second fitting part is fixed to the abutting part.

[0010] As an option, the first occlusal structure may be a serrated structure or a wavy structure, or the first occlusal structure may include a plurality of protrusions spaced apart.

[0012] As an optional solution, the upper end face of the extension plate is provided with a buffer groove.

[0013] As an optional solution, the abutment portion is provided with a material reduction reinforcement hole.

[0014] As an optional solution, the abutting part includes a second engagement structure, the second fitting part includes a third engagement structure, and the second engagement structure and the third engagement structure abut against each other;

[0015] Alternatively, the abutting portion includes a second engagement structure, the second engagement structure and the second fitting portion abutting against each other;

[0016] Alternatively, the second mating portion may include a third engagement structure, which abuts against the abutting portion.

[0017] As an optional solution, the first interlocking structure abuts against the first end face of the photovoltaic frame along a first direction, the second fitting portion is arranged at intervals with the first interlocking structure along the first direction, the second fitting portion abuts against the second end face of the photovoltaic frame along the first direction, and the second fitting portion abuts against and is fixed to the abutting portion along the first direction.

[0018] As an optional solution, the abutting portion abuts against the first sidewall of the photovoltaic frame along the second direction, the first fitting portion and the abutting portion are arranged at intervals along the second direction, and the first fitting portion abuts against the second sidewall of the photovoltaic frame along the second direction, wherein the first direction and the second direction are perpendicular to each other.

[0019] As an alternative, a relief groove is formed at the connection between the first fitting part and the second fitting part, and an extension edge extends from the second end face, with at least a portion of the extension edge being accommodated in the relief groove.

[0020] A photovoltaic system includes a photovoltaic module and a blocking device as described above. The photovoltaic module includes a photovoltaic frame and a photovoltaic body. The photovoltaic frame is fixed to the outside of the photovoltaic body, and the blocking device is installed on the photovoltaic frame.

[0021] This specification provides a blocking device comprising a blocking member and a support plate. The blocking member includes a connected abutment portion and a blocking portion. The end of the blocking portion includes a first engagement structure that abuts against the end face of a photovoltaic frame. The support plate includes a connected first fitting portion and a second fitting portion. The first fitting portion abuts against the photovoltaic frame, and the second fitting portion is fixed to the abutment portion.

In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] like Figure 1 As shown, this embodiment provides a photovoltaic system including a photovoltaic module 20 and a blocking device 10. The photovoltaic module 20 includes a photovoltaic frame 201 and a photovoltaic body 202. The photovoltaic frame 201 is fixed to the outside of the photovoltaic body 202, and the blocking device 10 is installed on the photovoltaic frame 201. The photovoltaic system provided in this embodiment, by installing the blocking device 10 on the photovoltaic frame 201, can effectively block snow accumulation on the photovoltaic module 20, avoiding the safety risks caused by snow sliding off the photovoltaic module 20.

[0037] It should be noted that, in this embodiment, as Figure 1 and Figure 2 As shown, the photovoltaic frame 201 includes a first end face 2011, a second end face 2012, a first sidewall 2013, and a second sidewall 2014. The first end face 2011 and the second end face 2012 are arranged at intervals, as are the first sidewall 2013 and the second sidewall 2014. Both the first end face 2011 and the second end face 2012 are connected to the first sidewall 2013, and both are arranged at an angle to the first sidewall 2013. Furthermore, in this embodiment, the photovoltaic frame 201 also includes an extension edge 2015, which extends inward from the second end face 2012 (i.e., towards the photovoltaic body 202).

[0038] The blocking device in the related technology can only be installed on a photovoltaic frame 201 of one type. When the shape of the photovoltaic frame 201 changes, especially when the shape of the first end face 2011 of the photovoltaic frame 201 changes slightly, the blocking device in the related technology cannot be stably and reliably fixed on the photovoltaic frame 201, which greatly reduces the adaptability and installation stability of the blocking device.

[0039] To solve the above problems, such as Figure 1 and Figure 2As shown, the blocking device 10 provided in this embodiment includes a blocking member 1 and a support plate 2. The blocking member 1 includes a connected abutment portion 11 and a blocking portion 12. The end of the blocking portion 12 includes a first engagement structure 1211, which abuts against the end face of the photovoltaic frame 201. The support plate 2 includes a connected first fitting portion 21 and a second fitting portion 22. The first fitting portion 21 abuts against the photovoltaic frame 201, and the second fitting portion 22 is fixed to the abutment portion 11. The blocking device 10 provided in this embodiment, through the mutual cooperation of the blocking member 1 and the support plate 2 on the photovoltaic frame 201, achieves the installation and fixation of the blocking device 10 on the photovoltaic frame 201. Furthermore, the blocking member 1 effectively blocks snow accumulation on the photovoltaic module 20, avoiding the safety risks caused by snow sliding off the photovoltaic module 20. Furthermore, by providing a first engagement structure 1211, and ensuring that the first engagement structure abuts against the end face of the photovoltaic frame 201, the blocking device 10 can maintain contact with the end face of the photovoltaic frame 201 even if the shape of the end face of the photovoltaic frame 201 changes. This improves the stability of the contact between the first engagement structure 1211 and the end face of the photovoltaic frame 201, thereby enhancing the installation stability of the entire blocking device 10 on the photovoltaic frame 201 and improving the adaptability of the blocking device 10. For example, the contact between the first engagement structure 1211 and the end face of the photovoltaic frame 201 can be a pressing engagement.

[0040] Optionally, in this embodiment, as Figure 1 and Figure 3 As shown, the first engagement structure 1211 is a serrated structure. By designing the first engagement structure 1211 as a serrated structure, it is ensured that the first engagement structure 1211 can stably abut against the end face of the photovoltaic frame 201, effectively improving the contact force and friction between the first engagement structure 1211 and the end face of the photovoltaic frame 201, ensuring the tightness of the contact between the first engagement structure 1211 and the end face of the photovoltaic frame 201, and also ensuring that the first engagement structure 1211 can adapt to the end face of photovoltaic frames 201 with different shapes. In other embodiments, the first engagement structure 1211 can also be a wavy structure. In other embodiments, the first engagement structure 1211 may also include multiple protrusions spaced apart.

[0041] Optionally, in this embodiment, the first engagement structure 1211 abuts against the first end face 2011 of the photovoltaic frame 201 along a first direction, the second fitting portion 22 is spaced apart from the first engagement structure 1211 along the first direction, the second fitting portion 22 abuts against the second end face 2012 of the photovoltaic frame 201 along the first direction, and the second fitting portion 22 abuts against and is fixed to the abutting portion 11 along the first direction. This arrangement ensures that the first engagement structure 1211 and the second fitting portion 22 cooperate to clamp and fix the photovoltaic frame 201 on both sides along the first direction, guaranteeing the stability of the blocking device 10 installed and fixed on the photovoltaic frame 201. It should be noted that the first end face 2011 and the second end face 2012 are spaced apart along the first direction. It should also be noted that the first direction, as shown by the arrow in the figure, is the thickness direction of the photovoltaic body 202.

[0042] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, the abutting portion 11 abuts against the first sidewall 2013 of the photovoltaic frame 201 along the second direction, the first fitting portion 21 is spaced apart from the abutting portion 11 along the second direction, and the first fitting portion 21 is fitted against the second sidewall 2014 of the photovoltaic frame 201 along the second direction, wherein the first direction and the second direction are perpendicular to each other. This arrangement allows the abutting portion 11 and the first fitting portion 21 to cooperate in clamping and fixing the photovoltaic frame 201 on both sides along the second direction. Furthermore, this arrangement ensures that the photovoltaic frame 201 is clamped by corresponding components on the blocking device 10 on both sides along the first direction and both sides along the second direction, further guaranteeing the stability of the entire blocking device 10 installed and fixed on the photovoltaic frame 201. It should be noted that the first sidewall 2013 and the second sidewall 2014 are spaced apart along the second direction. It should also be noted that the second direction, as indicated by the arrow in the figure, is the direction in which the photovoltaic body 202 and the photovoltaic frame 201 extend and tilt.

[0043] In this embodiment, as Figure 1 and Figure 3As shown, the blocking portion 12 includes an extension plate portion 121 and a blocking plate portion 122. The end of the extension plate portion 121 away from the photovoltaic frame 201 is connected to the blocking plate portion 122. The extension plate portion 121 and the blocking plate portion 122 are arranged at an angle. The end of the extension plate portion 121 near the photovoltaic frame 201 includes a first interlocking structure 1211. This arrangement allows snow on the photovoltaic module 20 to be blocked by the blocking plate portion 122 when it slides down the extension plate portion 121, thus avoiding the safety risks caused by snow sliding down the photovoltaic module 20. Furthermore, the structural design of the blocking portion 12 ensures that the blocking plate portion 122, which blocks snow, is as far away from the photovoltaic module 20 as possible, thereby reducing the shading effect of the blocking portion 12 on the photovoltaic module 20 and ensuring that the photovoltaic body 202 in the photovoltaic module 20 can receive more sunlight. Optionally, in this embodiment, the extension plate portion 121 and the blocking plate portion 122 are arranged vertically. It should be noted that in this embodiment, the extension plate portion 121 is connected to the abutment portion 11.

[0044] Optionally, in this embodiment, as Figure 3 As shown, an arc-shaped transition portion 1221 protrudes from the end of the baffle plate portion 122. By providing the arc-shaped transition portion 1221 at the end of the baffle plate portion 122, the end of the baffle plate portion 122 becomes smoother, thereby preventing the end of the baffle plate portion 122 from scratching the operator. In addition, by providing the arc-shaped transition portion 1221, the structural strength of the end of the baffle plate portion 122 is also effectively enhanced.

[0045] Optionally, in this embodiment, as Figure 1 and Figure 3 As shown, a buffer groove 1212 is provided on the upper end surface of the extension plate portion 121. By providing the buffer groove 1212, when snow on the photovoltaic module 20 slides down the extension plate portion 121 to the blocking plate portion 122, the buffer groove 1212 can play a certain role in buffering and blocking the sliding of the snow, thereby reducing the impact of large snowflakes on the blocking plate portion 122 and ensuring the reliability of the entire blocking portion 12 in blocking snow.

[0046] Optionally, in this embodiment, as Figure 1 and Figure 3As shown, the abutment portion 11 has a subtractive reinforcement hole 111. This design not only saves on the weight and material cost of the abutment portion 11, but also ensures the structural rigidity and strength of the abutment portion 11 and the entire blocking member 1. It should be noted that the design of the subtractive reinforcement hole 111 allows the abutment portion 11 and the extension plate portion 121 to form a closed frame structure, ensuring the strength of the entire blocking member 1. Optionally, in this embodiment, the extension plate portion 121 is recessed on the side facing the subtractive reinforcement hole 111 to form a buffer groove 1212. Optionally, in this embodiment, the entire blocking member 1 is a one-piece molded part, which facilitates the processing of the blocking member 1 and also ensures the structural strength of the blocking member 1.

[0047] In this embodiment, as Figure 1 and Figure 3 As shown, the abutting portion 11 includes a second engagement structure 112, and the second fitting portion 22 includes a third engagement structure 221. The second engagement structure 112 and the third engagement structure 221 abut against each other. This arrangement allows the abutting portion 11 and the second fitting portion 22 to engage in an alternating manner, ensuring the tightness and stability of the abutting portion 11 and the second fitting portion 22. Exemplarily, the abutting between the second engagement structure 112 and the third engagement structure 221 can be a pressing engagement. Optionally, in this embodiment, both the second engagement structure 112 and the third engagement structure 221 are serrated structures. In other embodiments, the second engagement structure 112 can also be a wavy structure, and the second engagement structure 112 can also include a plurality of protrusions spaced apart. The third engagement structure 221 can also be a wavy structure, and the third engagement structure 221 can also include a plurality of protrusions spaced apart. Optionally, in other embodiments, the abutting portion 11 may include a second engagement structure 112, which abuts against the second fitting portion 22. Optionally, in other embodiments, the second fitting portion 22 may include a third engagement structure 221, which abuts against the abutting portion 11.

[0048] Optionally, such as Figure 1 , Figure 2 and Figure 4As shown, a clearance groove 23 is formed at the connection between the first fitting portion 21 and the second fitting portion 22. At least a portion of the extended edge 2015 is accommodated in the clearance groove 23, thereby avoiding the extended edge 2015 extending from the second end face 2012 through the clearance groove 23. By setting the clearance groove 23 to avoid the extended edge 2015 of the photovoltaic frame 201, and by abutting the corresponding parts of the first fitting portion 21 and the second fitting portion 22 with the photovoltaic frame 201, the abutment constraint between the tray 2 and the photovoltaic frame 201 is achieved. The size of the clearance groove 23 can be appropriately increased so that the clearance groove 23 avoids extended edges 2015 of different sizes. Compared with the traditional method of using the clearance groove 23 to abut and adapt the extended edge 2015 to achieve the constraint between the tray 2 and the photovoltaic frame 201, the adaptability of the tray 2 is effectively improved.

[0049] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the first fitting portion 21 includes a first plate portion 211, a second plate portion 212, and a third plate portion 213 connected in sequence. The first plate portion 211 is connected to the second fitting portion 22, the second plate portion 212 is spaced apart from the second fitting portion 22, and the third plate portion 213 abuts against the second sidewall 2014. The second fitting portion 22, the first plate portion 211, and the second plate portion 212 together form an avoidance groove 23. The avoidance groove 23 can be formed by bending the first fitting portion 21 accordingly, making the operation convenient and ensuring the structural strength of the entire support plate 2. It should be noted that in this embodiment, the first plate portion 211 and the second fitting portion 22 are arranged perpendicularly, the first plate portion 211 and the second plate portion 212 are arranged perpendicularly, and the second plate portion 212 and the third plate portion 213 are arranged perpendicularly.

[0050] In addition, such as Figure 1 As shown, the blocking device 10 provided in this embodiment also includes a fastener 3. The fastener 3 is provided in both the second fitting part 22 and the abutting part 11. The fastener 3 is used to fix the second fitting part 22 and the abutting part 11 together.

[0051] Optionally, in this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the fastener 3 includes a bolt 31, a flat washer 32, and a spring washer 33. The bolt 31 passes sequentially through the spring washer 33, the flat washer 32, the second mating part 22, and the abutment part 11 into the subtractive reinforcement hole 111. The bolt 31 is threadedly connected to both the second mating part 22 and the abutment part 11. This structural design of the fastener 3 ensures the reliability of the fastener 3 in fixing the second mating part 22 and the abutment part 11, and is simple in structure and easy to operate. Optionally, the second mating part 22 has a first threaded hole 222, and the abutment part 11 has a second threaded hole 113, thereby facilitating the bolt 31 to pass through the first threaded hole 222 and the second threaded hole 113, and ensuring that the bolt 31 is threadedly connected to both the first threaded hole 222 and the second threaded hole 113. Alternatively, in other embodiments, the fastener 3 may be designed as a bolt 31 and a nut, such that the bolt 31 passes through the second mating part 22 and is threadedly connected to the abutment part 11, and the end of the bolt 31 after being threadedly connected to the abutment part 11 extends into the material reduction reinforcing hole 111 and is threadedly connected to the nut.

[0052] To facilitate understanding of the blocking device 10 disclosed in this embodiment, it is now combined with... Figure 1 The specific installation process of the blocking device 10 on the photovoltaic frame 201 is described below:

[0053] First, the second fitting part 22 of the tray 2 abuts against the second end face 2012 of the photovoltaic frame 201, and ensures that the first fitting part 21 of the tray 2 abuts against the second side wall 2014 of the photovoltaic frame 201; then, the blocking member 1 is placed on the tray 2, so that the abutting part 11 of the blocking member 1 abuts against the first side wall 2013 of the photovoltaic frame 201. At this time, the first interlocking structure 1211 abuts against the first end face 2011 of the photovoltaic frame 201, and the second interlocking structure 112 and the third interlocking structure 221 abut against each other; finally, the fastener 3 is screwed onto the second fitting part 22 and the abutting part 11.
