[0028] The following detailed description will further explain the present application with reference to the above mentioned drawings. DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The drawings show several embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments and is not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Referring to Figures 1 to 8 , the waste heat utilization device for the photovoltaic module 80 in an embodiment of the present application is shown, which comprises a support plate 10 for supporting the photovoltaic assembly 60 and a first clamping member 20 and a second clamping member 30 respectively arranged at both ends of the support plate 10. The first clamping member 20 comprises a cylindrical portion 21 and a flange portion 22 arranged at the top of the cylindrical portion 21. The second clamping member 30 comprises an arc-shaped clamping block with a notch on one side, and the notch is directed in the same direction as the length direction of the support plate 10. The support plate 10 is provided with an avoiding groove 11 below the second clamping member 30, so that when the second clamping member 30 on one side of a support plate 10 is clamped on the first clamping member 20 of another support plate 10, the support plate 10 will not interfere with the cylindrical portion 21.

[0033] Understandably, by setting a first snap-fit ​​20 on one side of the support plate 10 and a second snap-fit ​​30 on the other side, when two adjacent support plates 10 are connected in the length direction, one support plate 10 is placed on or connected to the other support plate 10, so that the first snap-fit ​​20 moves closer to the second snap-fit ​​30. The cylindrical part 21 moves through the relief groove 11 and moves towards the notch of the arc-shaped snap-fit ​​block under the guidance of the relief groove 11 until the cylindrical part 21 and the two ends of the notch are pressed and embedded into the center of the arc-shaped snap-fit ​​block, so that the arc-shaped snap-fit ​​block locks the cylindrical part 21, and the flange 22 above the cylindrical part 21 achieves height limitation, thereby fixing the connection between the two support plates 10. This method eliminates the need for additional clamps, effectively reducing the weight of the photovoltaic module 60 and the support plate 10. Furthermore, by strategically positioning the first snap-fit ​​member 20 and the second snap-fit ​​member 30, the spacing between the photovoltaic modules 60 on the two support plates 10 can be adjusted, or even eliminated, allowing the photovoltaic modules 60 to abut against each other to form a waterproof plane, thus reducing the need for breathable waterproof components and lowering overall costs. Moreover, this snap-fit ​​connection method is simple and direct, resulting in high installation efficiency. The simple installation method allows for robot-assisted installation, further increasing efficiency. Therefore, this invention solves the problem of the lack of an auxiliary connection structure for photovoltaic modules 60 in the prior art that reduces the installation cost of photovoltaic panels.

[0034] It should be noted that the integrated photovoltaic building material module combines photovoltaic modules and building materials into one unit. Using special materials and processes, the photovoltaic modules are made into forms such as roofs, exterior walls, and windows, and can be used directly as building materials, generating electricity while also serving as a building material. Specifically, the combined structure of the support plate 10 and the photovoltaic module in this application allows the structure to serve as a waterproof layer for the roof and also to generate photovoltaic power, further contributing to building energy conservation. Furthermore, the auxiliary connection structure of this application allows the integrated photovoltaic building material module to be easily and directly fixed to the roof, serving both as a waterproof layer and generating photovoltaic power, thus reducing overall installation costs.

[0035] As an example, and not a limitation, in some optional embodiments, the auxiliary connection structure also includes rivets 40, and a receiving groove 211 is provided on the cylindrical portion 21 for installing the rivets 40, which are used to connect with the roof support structure. In specific implementations, by providing the receiving groove 211 on the cylindrical portion 21 and by additionally providing rivets 40 to cooperate with the receiving groove 211, the connection strength between the two support plates 10 can be further strengthened to ensure the wind resistance of the fixed connection between the support plates 10. In addition, in specific implementations, the roof support structure connection is usually a roof purlin 80, which is fixedly connected to the roof purlin 80 by rivets 40. This allows the photovoltaic integrated module to be directly fixed to the roof through the support plate 10 without the need for other auxiliary connection support structures to connect the support plate 10 and the roof, greatly reducing costs. Furthermore, the rivet connection method is quick to install and improves the installation and fixing efficiency.

[0036] Specifically, the arc-shaped snap-fit ​​block includes an arc-shaped portion 31 and an arc-shaped block 32 disposed below the arc-shaped portion 31. The arc-shaped portion 31 and the support plate 10 enclose an arc-shaped space. The arc-shaped block 32 includes a main body portion 321 and clamp portions 322 disposed at both ends of the main body portion 321. The main body portion 321 is disposed within the arc-shaped space, and the clamp portions 322 are located outside the arc-shaped space and are elastic. In actual use, the elastic design of the clamp portions 322 makes it easy for the cylindrical portion 21 to be embedded in the center of the arc-shaped portion 31, and the connection is mainly made by rivets 40. When rivets 40 are not provided, the fixed connection between the two support plates 10 is achieved by the interference fit between the arc-shaped portion 31 and the cylindrical portion 21. Furthermore, it should be noted that in specific implementation, the support plate 10 can be made of a profiled metal plate. The cylindrical part 21 and the flanged part 22 can be formed by partially punching and trimming on the support plate 10, thus forming the cylindrical part 21 and the flanged part 22, that is, partially forming the first snap-fit ​​part 20. In addition, the arc-shaped part 31 can also be formed by partially punching and trimming on the support plate 10, and then combined with the arc block 32 to form the second snap-fit ​​part 30. Thus, most of the structure is made of the material of the support plate 10 itself, which reduces the overall weight and saves material costs.

[0037] Furthermore, the cross-sectional area of ​​the clamp part 322 is larger than that of the main body part 321 and the arc-shaped space. By limiting the cross-sectional area, i.e. the volume, of the clamp part 322, the clamp is fixed in a specific position, and the orientation of the notch is fixed, thereby ensuring that the clamp will not rotate or fall off, thus ensuring the normal use of the clamp.

[0038] Specifically, the auxiliary connection structure also includes a snap fastener 50, which includes a circular ring portion 51 and a column portion 52 disposed below the circular ring portion 51. The snap fastener 50 is sleeved on the column portion 21, and the circular ring portion 51 is located between the flange portion 22 and the arc-shaped portion 31. By setting the snap fastener 50 sleeved on the column portion 21, when the two support plates 10 are connected and fixed, the circular ring portion 51 abuts against the flange portion 22 and the arc-shaped portion 31, thereby filling the gap between the first snap fastener 20 and the second snap fastener 30, thereby restricting the degree of freedom in the height direction of the two and increasing the difficulty of separating the two from each other, so that the connection between the two support plates 10 will not shake, further enhancing the connection strength between the two support plates 10, thereby improving the overall wind resistance of the multiple photovoltaic modules 60.

[0039] Furthermore, the support plate 10 has a wave-shaped structure, with multiple first snap-fit ​​pieces 20 and second snap-fit ​​pieces 30 equidistantly distributed on the troughs of the support plate 10. In specific implementation, by setting the support plate 10 to a wave-shaped structure, multiple points of support are formed at the bottom of the photovoltaic module 60 to enhance the support strength. The wave-shaped support plate 10 also creates a heat dissipation channel below the photovoltaic module 60, thereby dissipating and reducing the heat generated during photovoltaic power generation. In addition, the wave-shaped support plate 10 provides space for the first snap-fit ​​pieces 20 and second snap-fit ​​pieces 30, preventing interference between the first snap-fit ​​pieces 20 and second snap-fit ​​pieces 30 and the photovoltaic module 60, or the need for additional mounting components to assist in installation. Furthermore, the multiple equidistantly arranged first snap-fit ​​pieces 20 and second snap-fit ​​pieces 30 enhance the structural strength between the two support plates 10.

[0040] As an example, and not a limitation, in some optional embodiments, a photovoltaic module 60 is mounted on the support plate 10, and the photovoltaic module 60 is fixedly connected to the crest of the support plate 10. Waterproof baffles 70 are provided on both sides of the bottom of the photovoltaic module 60. In actual implementation, gaps may appear between the two photovoltaic modules 60 due to assembly errors, and the waterproof effect achieved by tightly adhering the photovoltaic modules 60 together may not be ideal. Therefore, in actual implementation, additional adhesive can be used to bond the two photovoltaic modules 60 together. Furthermore, by providing waterproof baffles 70 on both sides of the bottom of the support plate 10, and by overlapping and adhesively bonding the waterproof baffles 70 on the two support plates 10, the waterproof effect is ensured while avoiding the use of adhesive on the photovoltaic module 60, which could easily damage the photovoltaic module 60 during disassembly and recycling.

[0041] Furthermore, the support plate 10 is also provided with a waterproof groove 12, which is located inside the first snap-fit ​​member 20 or the second snap-fit ​​member 30. In addition, in specific implementations, the overall waterproof effect can be further enhanced by setting the waterproof groove 12 and placing waterproof tape inside the groove.

[0042] In summary, the auxiliary connection structure of the photovoltaic building material integrated module in the above embodiments of this utility model, by setting a first snap-fit ​​member 20 on one side of the support plate 10 and a second snap-fit ​​member 30 on the other side, allows the two adjacent support plates 10 to be connected in the length direction. This is achieved by one support plate 10 being placed on or connected to the other support plate 10, causing the first snap-fit ​​member 20 to move closer to the second snap-fit ​​member 30. The cylindrical part 21 moves through the clearance groove 11 and moves towards the notch of the arc-shaped snap-fit ​​block under the guidance of the clearance groove 11 until the cylindrical part 21 and the two ends of the notch are pressed and embedded into the center of the arc-shaped snap-fit ​​block. This causes the arc-shaped snap-fit ​​block to lock the cylindrical part 21, and the flanged part 22 above the cylindrical part 21 achieves height-direction limitation, thereby fixing the connection between the two support plates 10. This method eliminates the need for additional clamps, effectively reducing the weight of the photovoltaic module 60 and the support plate 10. Furthermore, by strategically positioning the first snap-fit ​​member 20 and the second snap-fit ​​member 30, the spacing between the photovoltaic modules 60 on the two support plates 10 can be adjusted, or even eliminated, allowing the photovoltaic modules 60 to abut against each other to form a waterproof plane, thus reducing the need for breathable waterproof components and lowering overall costs. Moreover, this snap-fit ​​connection method is simple and direct, resulting in high installation efficiency. The simple installation method allows for robot-assisted installation, further increasing efficiency. Therefore, this invention solves the problem of the lack of an auxiliary connection structure for photovoltaic modules 60 in the prior art that reduces the installation cost of photovoltaic panels.

[0043] In addition, this utility model also proposes a photovoltaic system, including multiple photovoltaic modules that are equidistantly distributed and interconnected. Each photovoltaic module includes a photovoltaic component 60 and the aforementioned auxiliary connection structure for the photovoltaic component 60 disposed below the photovoltaic component 60. The auxiliary connection structure for the photovoltaic component 60 is used to connect two adjacent photovoltaic components 60 in the same column.
