Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic carports, in particular to a lap-jointed photovoltaic component connection structure and a photovoltaic carport roof. Background Art

[0002] The application scenarios of photovoltaic modules are becoming more and more extensive, such as photovoltaic roofs, photovoltaic facades, photovoltaic bricks, photovoltaic corridors, photovoltaic carports and other photovoltaic elements. By integrating photovoltaic modules into the roof of the photovoltaic carport, the photovoltaic modules can serve as part of the carport roof structure and generate electricity.

[0003] Some existing photovoltaic carport roofs generally use steel structures as the supporting structure of the roof. Aluminum alloy water guide troughs are installed on the steel structure for water conduction, and photovoltaic modules are mounted on the water guide troughs. This installation method of photovoltaic modules is prone to the following problems:

[0004] (1) Since many water channels need to be installed, the installation process is complicated and the cost is high.

[0005] (2) Since the photovoltaic modules are installed on the water gutter, the frame of the photovoltaic modules needs to be directly against the water gutter, which can easily cause deformation of the frame.

[0006] (3) Since the photovoltaic modules are installed on the gutter, under the action of gravity, the photovoltaic modules are easy to slide down along the slope of the carport roof, causing them to fall off the gutter.

[0007] (4) Compared with installing PV panels directly on the steel structure of the roof, installing PV panels on the gutter results in a higher center of gravity and is easily overturned in windy weather. Utility Model Content

[0051] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a lap-jointed photovoltaic assembly connection structure, which is used in the roof of a photovoltaic carport. The lap-jointed photovoltaic assembly connection structure includes a plurality of mounting brackets 100 and a plurality of photovoltaic assemblies 200. The lap-jointed photovoltaic assembly connection structure includes a plurality of photovoltaic assemblies 200 arranged in sequence along the slope direction of the slope of the carport roof. In any two adjacent photovoltaic assemblies 200 along the slope direction, the lower end of the relatively upper photovoltaic assembly 200a overlaps the upper end of the relatively lower photovoltaic assembly 200b, and the mounting bracket 100 is provided at the overlapping portion of the two.

[0052] refer to Figure 3 The mounting support 100 is used to be fixed on the slope, and specifically can be fixed on a slat (not shown) arranged on the slope. The mounting support 100 includes a support plate 110, a first extension portion 120 and a second extension portion 130. The support plate 110 is arranged perpendicular to the slope of the carport. The upper end of the first extension portion 120 along the slope direction of the slope and the upper end of the second extension portion 130 along the slope direction are both connected to the support plate 110, and the second extension portion 130 is located on the side of the first extension portion 120 away from the slope. A first hook 121 is provided at the lower end of the first extension portion 120 along the slope direction. A first protrusion 131 is provided at the lower end of the second extension portion 130 along the slope direction, and the first protrusion 131 protrudes toward the slope.

[0053] refer to Figure 4 and Figure 5The photovoltaic module 200 has an upper frame 210 and a lower frame 220 that are opposite to each other along the slope direction. The upper frame 210 is provided with a first flange 211 extending upward along the slope direction, and the lower frame 220 is provided with a second flange 221 extending upward along the slope direction. A second hook 212 is provided at the upper end of the first flange 211 along the slope direction. A second protrusion 222 is provided at the upper end of the second flange 221 along the slope direction, and the second protrusion 222 protrudes away from the slope surface.

[0054] Combination Figures 2 to 5 Among any two adjacent photovoltaic modules 200 along the slope direction, the second hook 212 of the relatively lower photovoltaic module 200b is used to hook the first hook 121 downward along the slope direction, and the second protrusion 222 of the relatively upper photovoltaic module 200a is used to hook the first protrusion 131 downward along the slope direction.

[0055] The above-mentioned overlapping photovoltaic assembly connection structure, the mounting bracket 100 is used to be fixed on the slope. Among the two photovoltaic assemblies 200 that are adjacent to each other along the slope direction, the second hook 212 of the relatively lower photovoltaic assembly 200b hooks the first hook 121 downward along the slope direction, so that the relatively lower photovoltaic assembly 200b can be hung on the mounting bracket 100 to prevent the photovoltaic assembly 200b from sliding down; the second protrusion 222 of the relatively upper photovoltaic assembly 200a hooks the first protrusion 131 downward along the slope direction, so that the hooking of the first protrusion 131 and the second protrusion 222 can also prevent the relatively upper photovoltaic assembly 200a from sliding down, and then the photovoltaic assembly 200 can be reliably installed on the slope of the roof of the carport through the mounting bracket 100. Moreover, since the lower end of the relatively upper photovoltaic component 200a of any two adjacent photovoltaic components 200 along the slope direction overlaps the upper end of the relatively lower photovoltaic component 200b, water can be guided to flow downward along the slope direction at the overlapping point of the two, thereby playing a water guiding role.

[0056] It can be seen that the above-mentioned overlapping photovoltaic assembly connection structure conducts water through overlapping photovoltaic assemblies, eliminating the installation of water guide grooves, simplifying the installation process and reducing costs. At the same time, the frame of the photovoltaic assembly 200 does not need to be supported on the water guide groove, avoiding the problem of frame deformation caused by this. Moreover, the photovoltaic assembly 200 can be reliably installed on the slope of the roof of the carport through the mounting bracket 100, effectively preventing the photovoltaic assembly 200 from sliding down. In addition, since the second protrusion 222 of the relatively upper photovoltaic assembly 200a hooks the first protrusion 131 downward along the slope direction, when the photovoltaic assembly 200a encounters strong winds, the first protrusion 131 blocks the second flange 221 and the second protrusion 222, which can prevent the photovoltaic assembly 200a from being lifted up, and play a role in resisting wind lifting.

[0057] Furthermore, the photovoltaic assembly 200 can be installed by hooking the second hook 212 of the upper frame 210 of the photovoltaic assembly 200 with the first hook 121 of the corresponding mounting support 100, and the second protrusion 222 of the lower frame 220 of the photovoltaic assembly 200 with the first protrusion 131 of the corresponding mounting support 100; conversely, the photovoltaic assembly 200 can be disassembled separately by unhooking the second hook 212 of the upper frame 210 of the photovoltaic assembly 200 from the first hook 121 of the corresponding mounting support 100, and unhooking the second protrusion 222 of the lower frame 220 of the photovoltaic assembly 200 from the first protrusion 131 of the corresponding mounting support 100. It can be seen that when the above-mentioned overlapping photovoltaic assembly connection structure is used for the roof of the photovoltaic carport, it can simultaneously meet the requirements of anti-slippage of the photovoltaic assembly, independent replacement of a single photovoltaic assembly, and wind resistance of the photovoltaic assembly.

[0058] Combination Figures 1 to 3 As shown, in one embodiment, the support plate 110 , the first protrusion 131 , and the second extension portion 130 form a first slot 132 , and when the second protrusion 222 is hooked with the first protrusion 131 , it is located in the first slot 132 .

[0059] In one embodiment, the length of the first protrusion 131 along the slope direction is greater than the length of the first slot 132 along the slope direction. In this way, the length of the first protrusion 131 is longer and the contact area with the second flange 221 is larger, so that the second flange 221 and the second protrusion 222 can be better blocked, and the photovoltaic component 200 can be more effectively protected from wind.

[0060] Please combine Figures 2 to 4 In one embodiment, the mounting bracket 100 includes a third extension portion 150, the upper end of the third extension portion 150 along the slope direction is connected to the support plate 110, and the upper end of the third extension portion 150 along the slope direction is provided with a third hook 151. The upper frame 210 is provided with a third flange 213 extending upward along the slope direction, and the upper end of the third flange 213 along the slope direction is provided with a fourth hook 214.

[0061] The fourth hook 214 of the relatively lower photovoltaic assembly 200b is used to hook the third hook 151 downward along the slope direction. In this way, the relatively lower photovoltaic assembly 200b can be hung on the mounting bracket 100 through the hooking of the fourth hook 214 and the third hook 151, thereby further strengthening the reliable connection between the photovoltaic assembly 200b and the mounting bracket 100 and preventing the photovoltaic assembly 200b from sliding down.

[0062] When installing the photovoltaic component 200, the fourth hook 214 of the upper frame 210 of the photovoltaic component 200 can be hooked onto the third hook 151 of the corresponding mounting support 100; conversely, the photovoltaic component 200 can be disassembled separately by unhooking the fourth hook 214 of the upper frame 210 of the photovoltaic component 200 from the third hook 151 of the corresponding mounting support 100.

[0063] Please combine Figures 2 to 4 In one embodiment, the first extension portion 120 and the third extension portion 150 are located between the first flange 211 and the third flange 213 of the relatively lower photovoltaic assembly 200b. In this way, an accommodation space can be formed between the first flange 211 and the third flange 213 of the photovoltaic assembly 200b, and the first extension portion 120 and the third extension portion 150 can be reliably placed in the accommodation space, so that the photovoltaic assembly 200b can be more reliably hung on the mounting bracket 100, preventing the photovoltaic assembly 200b from sliding down.

[0064] Please combine Figures 2 to 4 In one embodiment, the lower end of the third extension portion 150 along the slope direction is provided with an abutment portion 152. When the fourth hook 214 of the relatively lower photovoltaic assembly 200b hooks the third hook 151 downward along the slope direction, the abutment portion 152 abuts against the upper end of the upper frame 210 of the relatively lower photovoltaic assembly 200b along the slope direction downward. In this way, the connection between the upper frame 210 of the relatively lower photovoltaic assembly 200b and the mounting support 100 can be prevented from loosening along the slope direction, thereby further improving the reliability of the connection between the photovoltaic assembly 200b and the mounting support 100 and preventing the photovoltaic assembly 200b from sliding down.

[0065] The area of ​​the abutting surface of the abutting portion 152 is larger than the area of ​​the cross section of the third extension portion 150. Compared with the third extension portion 150 directly abutting against the upper frame 210 of the relatively lower photovoltaic assembly 200b, the abutting portion 152 with a larger area abuts against the upper frame 210 of the relatively lower photovoltaic assembly 200b, thereby making the connection between the upper frame 210 of the relatively lower photovoltaic assembly 200b and the mounting bracket 100 more reliable.

[0066] Please combine Figure 2 , Figure 3 and Figure 5In one embodiment, the mounting bracket 100 includes a fourth extension portion 160, and the upper end of the fourth extension portion 160 along the slope direction is connected to the support plate 110. The side of the fourth extension portion 160 facing the slope surface abuts against the upper frame 210 of the relatively lower photovoltaic assembly 200b, and the side of the fourth extension portion 160 facing away from the slope surface abuts against the lower frame 220 of the relatively upper photovoltaic assembly 200a. The fourth extension portion 160 extends downwardly beyond the upper frame 210 of the relatively lower photovoltaic assembly 200b along the slope direction. In this way, when the photovoltaic assembly 200b encounters strong winds, the fourth extension portion 160 can fully block the upper frame 210 of the relatively lower photovoltaic assembly 200b, thereby preventing the photovoltaic assembly 200b from being lifted by the wind, thereby playing an anti-wind lifting role.

[0067] Please refer to Figure 2 In one embodiment, a waterproof rubber strip 300 is sandwiched between the side of the fourth extension portion 160 facing the slope and the upper frame 210 of the relatively lower photovoltaic component 200b, thereby achieving a waterproof effect on the upper end of the relatively lower photovoltaic component 200b.

[0068] Please combine Figure 2 , Figure 3 and Figure 5 In one embodiment, the mounting bracket 100 includes a fourth extension portion 160, the upper end of the fourth extension portion 160 along the slope direction is connected to the support plate 110, and the lower end of the fourth extension portion 160 along the slope direction is provided with a fifth hook 161, and the fifth hook 161 is used to hook the lower end of the lower frame 220 of the relatively upper photovoltaic component 200a along the slope direction upward along the slope direction, thereby providing upward support for the relatively upper photovoltaic component 200a, and can further prevent the photovoltaic component 200a from sliding down.

[0069] Please combine Figure 2 and Figure 5 In one embodiment, a protrusion 230 is provided on a side of the lower frame 220 facing downward along the slope direction, and the protrusion 230 is provided with a groove 231, and the opening of the groove 231 faces the side where the slope surface is located.

[0070] Among them, a water-conducting rubber strip 232 is installed in the groove 231 of the protrusion 230 of the lower frame 220 of the relatively upper photovoltaic component 200a, and the part of the water-conducting rubber strip 232 extending out of the groove 231 is tilted downward for guiding water downward, thereby achieving a waterproof effect on the upper end of the relatively lower photovoltaic component 200b.

[0071] refer to Figure 5 and Figure 6In one embodiment, a hooking groove 233 is formed between a side of the lower frame 220 facing downward along the slope direction and a side of the protrusion 230 facing the slope, and the fifth hook 161 is hooked in the hooking groove 233 .

[0072] Please combine Figure 1 , Figure 6 and Figure 7 In one embodiment, the lap-jointed photovoltaic module connection structure further includes an anti-slip support 400, wherein a support 410 is provided at the lower end of the anti-slip support 400 along the slope direction, wherein the support 410 is provided with a bracket 411, and the bracket 411 has an opening upward along the slope direction. The protrusion 230 of the lower frame 220 of the photovoltaic module 200z at the lowest end along the slope direction can enter the bracket 411 from the opening of the bracket 411 and abut against the groove wall of the bracket 411.

[0073] In this embodiment, the downward sliding force of each photovoltaic component 200 arranged in sequence along the slope direction can be transmitted to the support 410 through the protrusion 230 of the lower frame 220 of the lowest photovoltaic component 200z, so that the support 410 can fully support each photovoltaic component 200 upward along the slope direction, and can fully and reliably prevent the photovoltaic component 200 from sliding down.

[0074] Please combine Figure 1 , Figure 6 and Figure 7 In one embodiment, the anti-slip support 400 includes a first support plate 420 and a second support plate 430 which are perpendicular to each other. The first support plate 420 is perpendicular to the slope surface, and the second support plate 430 is parallel to the slope surface. The end of the first support plate 420 away from the slope surface is fixedly connected to the end of the second support plate 430 which is upward along the slope direction. The support 410 is provided at the lower end of the second support plate 430 along the slope direction.

[0075] Please combine Figure 1 , Figure 6 and Figure 7 In one embodiment, the anti-slip support 400 includes a reinforcing inclined plate 440. The two ends of the reinforcing inclined plate 440 are respectively connected to the first support plate 420 and the second support plate 430, and are inclined to the first support plate 420 and the second support plate 430. The reinforcing inclined plate 440 enhances the support strength of the anti-slip support 400, so that each photovoltaic module 200 can be supported more reliably.

[0076] Please combine Figure 1 , Figure 6 and Figure 7 In one embodiment, the anti-slip support 400 includes a mounting plate 450, and the mounting plate 450 is perpendicular to the first support plate 420. The mounting plate 450 can be fixed to the sandalwood strips arranged on the slope surface by bolt connection or the like. The lower end of the mounting plate 450 along the slope direction is fixedly connected to an end of the first support plate 420 close to the slope surface.

[0077] Please combine Figure 1 , Figure 6 and Figure 7 In one embodiment, the support 410 includes a first support wall 413 and a second support wall 414, one end of the first support wall 413 is fixedly connected to the lower end of the second support plate 430 along the slope direction, and the other end of the first support wall 413 is fixedly connected to one end of the second support wall 414, so that the first support wall 413, the second support wall 414 and the second support plate 430 together form a bracket 411. When the protrusion 230 of the lower frame 220 of the photovoltaic assembly 200z at the lowest end along the slope direction is located in the bracket 411, it abuts against the first support wall 413. In this way, the bracket 411 can wrap the protrusion 230, achieve more reliable cooperation, and effectively prevent the photovoltaic assembly 200 from sliding down.

[0078] Please combine Figure 1 , Figure 6 and Figure 7 In one embodiment, a boss 412 is provided in the groove wall of the bracket 411, and the boss 412 is located at the connection between the second support plate 430 and the first support wall 413. The lower side of the protrusion 230 along the slope direction abuts against the first support wall 413. The side of the protrusion 230 facing the slope abuts against the boss 412, and the side facing away from the slope abuts against the second support wall 414. It can be seen that by providing the boss 412, the protrusion 230 can be closely matched with the bracket 411, so that the support 410 can more reliably support the photovoltaic module 200 to prevent the photovoltaic module 200 from sliding down. At the same time, the protrusion 230 has a good transition effect on the transfer of the load caused by the sliding of the photovoltaic module 200.

[0079] When installing the lap-type photovoltaic assembly connection structure in the embodiment of the present application, first fix the strips on the slope of the carport. Fix the anti-skid support 400 on the corresponding strips. First install the photovoltaic assembly 200z at the lowest end along the slope direction. Specifically, hook the second hook 212 of the upper frame 210 of the photovoltaic assembly 200z with the first hook 121 of its corresponding mounting support 100, and hook the fourth hook 214 of the upper frame 210 of the photovoltaic assembly 200z with the third hook 151 of its corresponding mounting support 100. In this way, the photovoltaic assembly 200z is connected to the corresponding mounting support 100. Then, move the photovoltaic assembly 200z downward so that its protrusion 230 enters the bracket 411 to achieve upward support for the photovoltaic assembly 200z. Next, fix the mounting support 100 connected to the upper end of the photovoltaic assembly 200z along the slope direction on the strips corresponding to the mounting support 100. At this point, the installation of the photovoltaic component 200z at the lowest end along the slope direction is completed.

[0080] The installation of other photovoltaic components 200 can refer to the following process. First, hook the second hook 212 of the upper frame 210 of the photovoltaic component 200 with the first hook 121 of the corresponding mounting support 100, and hook the fourth hook 214 of the upper frame 210 of the photovoltaic component 200 with the third hook 151 of the corresponding mounting support 100, so that the photovoltaic component 200 is connected to the corresponding mounting support 100. Then, hook the second protrusion 222 of the lower frame 220 of the photovoltaic component 200 with the first protrusion 131 of the corresponding mounting support 100, that is, the lower frame 220 of the photovoltaic component 200 is matched with the corresponding mounting support 100. Then, fix the mounting support 100 connected to the upper end of the photovoltaic component 200z along the slope direction on the corresponding sandalwood bar of the mounting support 100. At this point, the installation of the photovoltaic component 200z is achieved.

[0081] It can be understood that the second hook 212 has a certain elastic deformation ability. When the second hook 212 is connected to the first hook 211, an external force can be applied to move the photovoltaic component 200 upward relative to the mounting bracket 100 along the slope direction. In the process of the second hook 212 passing through the first hook 211, the second hook 212 is blocked and squeezed by the first hook 211, so that the second hook 212 can pass over the first hook 211 through its elastic deformation and move to the upper side of the first hook 211, thereby hooking the first hook 211. At the same time, the second hook 212 has a certain hardness, so that when the second hook 212 hooks the first hook 211, it has a certain support strength to achieve reliable hanging of the photovoltaic component 200.

[0082] Similarly, the second protrusion 222 and the fourth hook 214 both have a certain elastic deformation ability to facilitate the cooperation between the second protrusion 222 and the first protrusion 131, and the cooperation between the fourth hook 214 and the third hook 151. Similarly, the second protrusion 222 and the fourth hook 214 both have a certain hardness to facilitate the second protrusion 222 to have a certain support strength when hooked with the first protrusion 131, and the second protrusion 222 to have a certain support strength when cooperated with the first protrusion 13, so as to achieve reliable hanging of the photovoltaic 200. Among them, the cooperation process of the second protrusion 222 and the first protrusion 131, and the cooperation process of the fourth hook 214 and the third hook 151 are similar to the cooperation process of the second hook 212 and the first hook 211, and will not be repeated here.

[0083] The disengagement process between the second protrusion 222 and the first protrusion 131 , the disengagement process between the fourth hook 214 and the third hook 151 , and the disengagement process between the second hook 212 and the first hook 211 are opposite to their respective engagement processes, and will not be described in detail.

[0084] In practical applications, the overlapping photovoltaic module connection structure includes not only a plurality of photovoltaic modules arranged in sequence along the slope direction, but also a plurality of photovoltaic modules arranged in sequence in a direction perpendicular to the slope. The upper frames of the photovoltaic modules adjacent to each other in the direction perpendicular to the slope are adjacent to each other, and the lower frames are adjacent to each other.

[0085] Please refer to Figure 8 In one embodiment, in two adjacent frames along the direction perpendicular to the slope, the first frame 240 has a first extension 241 and a second extension 242 extending toward the second frame 250, and the second frame 250 has a third extension 251 and a fourth extension 252 extending toward the first frame 240. The first extension 241 is located on the side of the second extension 242 away from the slope surface, and the third extension 251 is located on the side of the fourth extension 252 away from the slope surface. The first extension 241 and the third extension 251 are sealed together, and the second extension 242 and the fourth extension 252 are sealed together, so that the four form a water channel to facilitate drainage of the overlapping photovoltaic module connection structure.

[0086] It can be understood that in this embodiment, the two adjacent frames along the direction perpendicular to the slope can be the upper frames of two adjacent photovoltaic modules along the direction perpendicular to the slope, or the lower frames of two adjacent photovoltaic modules along the direction perpendicular to the slope.

[0087] Please refer to Figure 8 In one embodiment, a water retaining plate 243 is provided at one end of the second extension 242 close to the fourth extension 252, and the water retaining plate 243 protrudes from the second extension 242 and the fourth extension 252 in a direction away from the slope. When encountering heavy rain, the rainwater can flow away from the water guide space enclosed by the water retaining plate 243, the first frame 240 and the second extension 242 under the blocking effect of the water retaining plate 243, so as to minimize the rainwater passing between the second extension 242 and the fourth extension 252, and the waterproof effect is better. The water retaining plate and the second extension are integrally formed to ensure the waterproofness between the two.
