[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the support member provided by the present invention and the photovoltaic installation structure for a distributed photovoltaic system are described in detail below in conjunction with the accompanying drawings.

[0031] At present, photovoltaic power generation has many advantages. First of all, it is a green energy that uses solar energy to generate electricity without polluting the environment. Among them, distributed photovoltaic power generation refers specifically to photovoltaic power generation facilities that are built near the user's site and operate in a way that the user generates electricity for their own use, the excess electricity is connected to the Internet, and the distribution system is balanced and regulated. Distributed photovoltaic power generation follows the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization, making full use of local solar energy resources to replace and reduce fossil energy consumption.

[0032] Existing distributed photovoltaic systems are mainly divided into industrial and commercial photovoltaic systems and household photovoltaic systems. Industrial and commercial photovoltaic systems are installed in factory buildings, commercial buildings and other scenes; while household photovoltaic power generation systems refer to photovoltaic systems in residential building areas, for example: installed in residential roofs, courtyards and other places, which can make full use of the electricity generated by the photovoltaic system. However, when household photovoltaic arrays are used on roofs, there is a gap between two adjacent photovoltaic panels. When it rains, rainwater will fall into the gap, so it is necessary to install waterproof components between two adjacent photovoltaic panels to drain the water.

[0033] However, in the existing roof structure, an M-shaped trough 20 is used for drainage. A support member 10 is provided on the trough 20. The water flowing down between the two photovoltaic panels will flow into the trough 20 through the guide groove 11 on the support member 10. However, the guide groove 11 on the support member 10 is often very small. When the rain is heavy, the tension between the rainwater may cause part of the rainwater to penetrate out of the trough 20, resulting in leakage.

[0034] In order to solve the above problems, Figures 1 to 6 As shown, the utility model discloses a support member 10 and a photovoltaic installation structure. Photovoltaic modules 100 are fixedly connected through the photovoltaic installation structure, wherein the support member 10 is used to support the photovoltaic modules 100.

[0035] The support member 10 has a guide groove 11 extending along a first direction, and the guide groove 11 is used to guide the liquid to flow toward the liquid collecting tank 20. The support member 10 also has at least one pair of anti-overflow portions 12. In a second direction intersecting with the first direction, the same pair of anti-overflow portions 12 are respectively arranged on both sides of the guide groove 11, and the anti-overflow portions 12 are used to block the liquid from flowing along the second direction to prevent the liquid in the guide groove 11 from overflowing in the second direction.

[0036] When in use, rainwater can be guided into the liquid collecting tank 20 through the guide groove 11 on the support member 10. When the rainwater is too heavy, since the anti-overflow parts 12 are arranged on both sides of the guide groove 11, the anti-overflow parts 12 can block the water in the guide groove 11 from flowing in the second direction, so that the rainwater in the guide groove 11 cannot overflow in the second direction and can only flow to the liquid collecting tank 20 in the first direction.

[0037] The support member 10 of the utility model is provided with anti-overflow parts 12 on both sides of the guide groove 11, and the anti-overflow parts 12 can block rainwater from flowing in the second direction, thereby reducing the risk of rainwater in the guide groove 11 overflowing in the second direction, thereby reducing the occurrence of water leakage.

[0038] It can be understood that the anti-overflow portion 12 is a raised structure formed by the support member 10 in the setting direction of the photovoltaic component 100. Since the anti-overflow portion 12 is a raised structure formed in the setting direction of the photovoltaic component 100, after assembly, the raised structure can block rainwater from flowing along the second direction. At the same time, the raised structure extends along the first direction, thereby blocking rainwater flowing along the second direction and guiding rainwater to flow toward the liquid collection tank 20.

[0039] It should also be noted that in the same pair of overflow prevention parts 12, the opposite side of the overflow prevention part 12 is connected to the groove wall of the corresponding guide groove 11 to increase the depth of the guide groove 11. Since the overflow prevention part 12 itself is a convex structure formed toward the setting direction of the photovoltaic module 100, after one side of the overflow prevention part 12 is connected to the groove wall of the guide groove 11, the depth of the guide groove 11 can be increased, thereby increasing the difficulty of rainwater overflowing the guide groove 11 and further reducing the occurrence of water leakage.

[0040] The support member 10 of the present invention is further described below in conjunction with a specific embodiment. In this embodiment, the first direction is the x-axis direction, the second direction is the y-axis direction, and the third direction is the z-axis direction, and the x-axis, y-axis, and z-axis are perpendicular to each other.

[0041] like Figures 1 to 4The first embodiment of the utility model shown in the figure discloses a support member 10, including: a first support plate 111 and a side plate 112. The first support plate 111 is arranged in a direction parallel to the first direction and the second direction; there are two side plates 112, both of which are perpendicular to the first support plate 111, and the two side plates 112 are arranged at intervals along the second direction, and the first support plate 111 is connected between the two side plates 112 to form a guide groove 11. In other words, Figure 1 As shown, the first support plate 111 is arranged perpendicular to the z-axis, the side plate 112 is arranged perpendicular to the y-axis, and the two side plates 112 are arranged parallel and spaced apart on the y-axis. Therefore, the two side plates 112 and the guide groove 11 form a U-shaped guide groove 11, and the guide groove 11 can guide rainwater to flow toward the collection tank 20 along the x-axis.

[0042] The support member 10 of the utility model forms a U-shaped guide groove 11, which can more effectively utilize space under the same width compared with the V-shaped groove in the prior art, so it can accommodate more accumulated water, that is, the volume is larger, making it less likely for rainwater to overflow.

[0043] It should be noted that, in the present embodiment, the side panel 112 and the first support panel 111 are perpendicular to each other, but this is not restrictive. In some other embodiments not shown in the figure, the side panel 112 and the first support panel 111 may not be perpendicular to each other, and the angle between the side panel 112 and the first support panel 111 may range from 45° to 135°, for example: 45°, 50°, 80°, 89°, 91°, 120°, 135°, etc., all within the protection scope of the present utility model.

[0044] It should also be noted that, in the present embodiment, the two side panels 112 are arranged in parallel, which is also not restrictive. In some other embodiments not shown in the figure, the two side panels 112 may not be parallel. Under the premise of not violating the inventive concept and principle of the present invention, the above situations are all within the protection scope of the present invention.

[0045] In this embodiment, a mounting portion 13 for connecting with the pressing block 30 is provided on the first support plate 111. Since the guide groove 11 in this embodiment is a U-shaped structure with a larger internal space, the mounting portion 13 can be provided to connect with the pressing block 30, so that the first support plate 111 is used to support the photovoltaic module 100, so that rainwater flowing between the photovoltaic modules 100 directly enters the guide groove 11, and prevents water leakage while achieving multiple uses of one object. In this embodiment, the mounting portion 13 is a first mounting hole that penetrates the first support plate 111 in the y-axis direction.

[0046] It should be noted that, in the present embodiment, the mounting portion 13 is a first mounting hole, but this is not restrictive. In some other embodiments not shown in the figure, the mounting portion 13 can also be a structure such as bolts and nuts fixedly connected to the first support plate 111. As long as the structure can be connected to the pressure block 30, it is within the protection scope of the present utility model.

[0047] In this embodiment, there are two overflow prevention parts 12, and each side plate 112 is connected to one overflow prevention part 12. Furthermore, the overflow prevention part 12 includes: an overflow prevention plate 121 and a transition plate 122. The length direction of the overflow prevention plate 121 is arranged along the first direction, that is, the x-axis direction. The overflow prevention plate 121 is connected to the corresponding side plate 112 and is located on the side away from the first support plate 111, thereby increasing the depth of the guide groove 11. The transition plate 122 is connected to the overflow prevention plate 121, and the transition plate 122 is used to connect with the liquid collecting tank 20. By setting the overflow prevention plate 121 and connecting the overflow prevention plate 121 to the side of the corresponding side plate 112 away from the first support plate 111, it is equivalent to extending the height of the side plate 112, thereby increasing the depth of the guide groove 11, so that the rainwater in the guide groove 11 is more difficult to overflow, thereby further reducing the occurrence of water leakage.

[0048] It should be noted that the connection position of the transition plate 122 and the corresponding side plate 112 can form an angle, and the transition plates 122 of the two overflow prevention parts 12 are away from each other in the direction away from the first support plate 111 to expand the notch of the guide groove 11. Of course, this is not restrictive, and the connection position of the transition plate 122 and the corresponding side plate 112 can also form a plane.

[0049] Please refer to Figure 1 The side plates 112 and the anti-overflow plate 121 connected to each other have the same width direction, and are arranged along the third direction, that is, the z-axis direction. In other words, the side plates 112 and the anti-overflow plate 121 are connected to each other to form a planar plate structure, so that the anti-overflow plate 121 can be used to the maximum extent to increase the depth of the guide groove 11. In addition, since the transition plate 122 is connected to the anti-overflow plate 121 to form a planar plate structure, and the transition plate 122 is directly connected to the anti-overflow plate 121, when Figure 3 As shown, after the support member 10 is installed on the liquid collecting tank 20, a stable triangular support structure is formed between the planar plate structure formed by connecting the transition plate 122, the anti-overflow plate 121 and the side plate 112, and the inner wall 23 of the liquid collecting tank 20, which effectively prevents the transition plate 122, the anti-overflow plate 121 and the side plate 112 from deforming, and can effectively limit the displacement of the first support plate 111 in the second direction, thereby improving the stability of the first support plate 111 in supporting the photovoltaic module.

[0050] It should be noted that, in the present embodiment, the width direction of the side plate 112 and the width direction of the anti-overflow plate 121 are both arranged along the third direction, that is, the z-axis direction, but this is not restrictive, and in some other embodiments not shown in the figure, the width direction of the side plate 112 and the width direction of the anti-overflow plate 121 may also form an angle with the third direction. Without violating the principle and inventive concept of the present utility model, the above situations are all within the protection scope of the present utility model.

[0051] like Figure 1 As shown, in this embodiment, the anti-overflow plate 121 and the transition plate 122 are connected to form an arc structure. The arc top of the arc structure is oriented in the same direction as the opening of the guide groove 11, both of which are oriented toward the direction in which the photovoltaic module 100 is set. In this embodiment, the anti-overflow plate 121 becomes a part of the groove wall of the guide groove 11 by connecting with the side plate 112, which is equivalent to increasing the height of the groove wall, which is equivalent to increasing the depth of the guide groove 11, so that the rainwater in the guide groove 11 is more difficult to overflow, thereby further reducing the occurrence of water leakage. The anti-overflow plate 121 and the transition plate 122 are connected to form an arc structure. The anti-overflow plate 121 can also increase the width of the notch of the guide groove 11 in the y-axis direction, reduce the probability of water droplets overflowing due to tension, and the surface of the arc structure can also guide rainwater back to the guide groove 11, further reducing the risk of rainwater overflowing the guide groove 11.

[0052] It is understandable that, in the present embodiment, the position where the anti-overflow plate 121 is connected to the transition plate 122 forms an arc structure. However, this is not restrictive. In some other embodiments not shown in the figure, the position where the anti-overflow plate 121 is connected to the transition plate 122 can also form an angle structure. Without violating the principle and inventive concept of the present utility model, the above situations are all within the protection scope of the present utility model. Therefore, from the perspective of manufacturing process, the position where the anti-overflow plate 121 is connected to the transition plate 122 adopts an arc structure, which not only makes the anti-overflow part 12 easier to form, but also has better mechanical properties and saves more materials.

[0053] like Figure 1 As shown, the support member 10 further includes: a connection portion 15, two connection portions 15, located at both ends of the support member 10 in the y-axis direction, and used to connect with the liquid collecting tank 20. The connection portions 15 are arranged one-to-one with the anti-overflow portion 12, each connection portion 15 is connected to the corresponding anti-overflow portion 12, and the connection portion 15 is detachably connected to the liquid collecting tank 20. By providing the connection portion 15, the support member 10 can be detachably connected with the liquid collecting tank 20 through the connection portion 15, which is convenient for later maintenance and replacement.

[0054] In this embodiment, the connecting part 15 includes: a second support plate 151 and a mounting plate 152, the second support plate 151 is parallel to and abuts the support surface 21, and the second support plate 151 is connected to the anti-overflow part 12; the mounting plate 152 is perpendicular to and connected to the second support plate 151, and the mounting plate 152 is connected to the outer wall 22 of the liquid collecting tank 20.

[0055] The relationship between the support member 10 and the photovoltaic installation structure of this embodiment is described in detail below in conjunction with specific application scenarios.

[0056] like Figure 3 and Figure 4 As shown, a photovoltaic installation structure for a distributed photovoltaic system is disclosed. The photovoltaic installation structure can be used for household photovoltaic power generation systems such as rooftop power stations and courtyard power stations, and can also be used for industrial and commercial photovoltaic systems used in factories, commercial buildings, etc.

[0057] The photovoltaic system comprises the above-mentioned support member 10, a pressing block 30 and a liquid collecting tank 20. The liquid collecting tank 20 is arranged along a first direction, the support member 10 is erected at the notch position of the liquid collecting tank 20 along a second direction, and the pressing block 30 is connected to the support frame.

[0058] The collecting tank 20 is an M-shaped tank, the length direction of the collecting tank 20 is a first direction, that is, the x-axis direction; the width direction of the collecting tank 20 is a second direction, that is, the y-axis direction; the height direction of the collecting tank 20 is a third direction, that is, the z-axis direction.

[0059] The outer wall 22 of the liquid collecting tank 20 is perpendicular to the y-axis, and a second mounting hole is provided on the outer wall 22 of the liquid collecting tank 20. The mounting plate 152 is parallel to and fits the outer wall 22 of the liquid collecting tank 20. A third mounting hole corresponding to the second mounting hole is provided on the mounting plate 152. Bolts are sequentially inserted into the second mounting hole and the third mounting hole, and bolts are provided on the bolts. The mounting plate 152 is fixedly connected to the outer wall 22 of the liquid collecting tank 20 by bolts and nuts.

[0060] The inner wall 23 of the liquid collecting tank 20 and the outer wall 22 of the liquid collecting tank 20 are connected to form a support surface 21, and the support surface 21 is located at the notch position of the liquid collecting tank 20, and the support surface 21 is perpendicular to the z-axis direction. The second support plate 151 is perpendicular to the mounting plate 152, that is, the second support plate 151 is parallel to the support surface 21, and the second support plate 151 abuts against the support surface 21, and one end of the second support plate 151 on the y-axis is connected to the mounting plate 152, and the other end is connected to the transition plate 122 of the overflow prevention part 12. The bottom of the guide groove 11 is located inside the liquid collecting tank 20, and the first support plate 111 abuts against the inner wall 23 of the liquid collecting tank 20 at the connection position with the side plate 112.

[0061] In this embodiment, the support plate is supported on the support surface 21 of the liquid collecting tank 20 by the second support plate 151. At the same time, the first support plate 111 and the side plate 112 are connected to the inner wall 23 of the liquid collecting tank 20, which increases the force points, improves the bearing capacity of the support member 10, prevents the support member 10 from deforming, and improves the stability and reliability of supporting the photovoltaic module 100.

[0062] It is understandable that if Figure 4 As shown, when in use, there may be a plurality of support members 10, and the plurality of support members 10 are spaced apart on the liquid collecting tank 20 along the first direction.

[0063] The pressing block 30 is detachably connected to the bottom of the guide groove 11, that is, the pressing block 30 is used to press the photovoltaic component 100 against the bottom of the guide groove 11. At the same time, a limiting space is formed between the pressing block 30 and the groove wall of the guide groove 11 for limiting the photovoltaic component 100 in the second direction.

[0064] Specifically in the first embodiment, the pressing block 30 includes: a pressing arm 31 and a connecting plate 32. There are two pressing arms 31. In the second direction, the two pressing arms 31 are arranged at intervals. The connecting plate 32 is connected between the two pressing arms 31. A through hole is provided on the connecting plate 32. The through hole corresponds to the first mounting hole on the first support plate 111. The bolt passes through the through hole and is fixedly connected to the first mounting hole. When in use, Figure 3 As shown, the pressing block 30 is located between two adjacent photovoltaic modules 100 , and the two pressing arms 31 respectively press the corresponding photovoltaic modules 100 onto the first support plate 111 , thereby fixing the photovoltaic modules 100 .

[0065] In this embodiment, the pressing arm 31 includes: a pressing plate 311 and a limiting plate 312. The pressing plate 311 is arranged in parallel with the first support plate 111, and is used to apply pressure in the z-axis direction to the photovoltaic assembly 100 to press the photovoltaic assembly 100 against the first support plate 111. The limiting plate 312 is connected to the pressing plate 311. The limiting plate 312 is arranged in parallel with the corresponding side plate 112, and a limiting space is formed between the limiting plate 312 and the corresponding side plate 112 to limit the displacement of the photovoltaic assembly 100 in the second direction. By setting the pressing arm 31, not only can the photovoltaic assembly 100 be pressed against the first support plate 111, but also the side plate 112 of the guide groove 11 can be used to limit the position of the photovoltaic assembly 100 in the second direction, thereby improving the stability and reliability of the assembly of the photovoltaic assembly 100.

[0066] like Figure 3As shown, in this embodiment, the photovoltaic installation structure further includes: an anti-slip member 40, which is arranged between the bottom of the guide groove 11 and the photovoltaic assembly 100, that is, between the first support plate 111 and the photovoltaic assembly 100. By setting the anti-slip member 40, the position of the photovoltaic assembly 100 can be prevented, and the stability of the assembly of the photovoltaic assembly 100 can be further improved.

[0067] It should be noted that, in this embodiment, the anti-slip member 40 is a piercing device, which is pre-installed on the first support plate 111 by welding. Figure 5 and Figure 6 In another embodiment of the embodiment shown, the bottom of the guide groove 11 is provided with an anti-skid structure 14, which is a protrusion formed directly on the first support plate 111 by mechanical processing, and can also play an anti-skid role, and therefore, is also within the protection scope of the present utility model.

[0068] Whether the puncture device is welded to the first support plate 111 by welding, or the puncture is directly formed on the first support by machining, the steps in the installation process of the photovoltaic module 100 are reduced, and the installation efficiency is greatly improved.

[0069] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
