Description

Technical Field

[0001] The embodiments in this application relate to the field of photovoltaic equipment technology, and in particular to an interlocking component and a photovoltaic power station. Background Technology

[0002] In related technologies, photovoltaic modules can be installed and fixed on the corrugated steel roof using mounting components such as clamps and clamps, so that the photovoltaic modules can be stably set on the corrugated steel roof and oriented towards the light source, ensuring the stable conversion of light energy by the photovoltaic system.

[0003] However, most rooftop photovoltaic (PV) modules cannot be stepped on, so maintenance platforms are usually installed next to the PV modules for users to walk on in order to clean or maintain them. However, installing maintenance platforms can increase the construction cost of PV power plants, and the platforms also occupy a certain amount of roof space, which affects the area where PV modules can be installed. Utility Model Content

[0004] This application provides several embodiments of an interlocking component and a photovoltaic power station, aiming to achieve overall connection and assembly of photovoltaic modules, reduce the need for maintenance pedals, and improve the practicality and reliability of the interlocking component.

[0005] An embodiment of this application proposes an interlocking assembly including a first lock, a second lock, and a fastener. The first lock has a mounting groove and two opposing first sidewalls, each with a first connecting hole communicating with the mounting groove. The second lock is insertable into the mounting groove and has two opposing second sidewalls, each with a second connecting hole. The fastener is inserted into the first and second connecting holes and connects the first and second locks. The first lock is used to connect a sidewall of a photovoltaic module parallel to the corrugated steel sheet, and the second lock is used to connect another adjacent sidewall of a photovoltaic module parallel to the corrugated steel sheet.

[0006] In one embodiment, the interlocking assembly has a height direction. The first sidewall has a plurality of first connection holes arranged along the height direction, and the fastener can be inserted into any of the first connection holes. And / or, the second sidewall has a plurality of second connection holes arranged along the height direction, and the fastener can be inserted into any of the second connection holes.

[0007] In one embodiment, the fastener includes a fixed rod, a movable rod, and an elastic element. The fixed rod is inserted into the first connecting hole and connected to the first lock. The fixed rod has a receiving hole. The movable rod is movably inserted through the receiving hole along the axis of the fixed rod and can be inserted into the second connecting hole. The elastic element is disposed in the receiving hole and connects the fixed rod and the movable rod.

[0008] In one embodiment, the fixing rod is threadedly connected to the first lock.

[0009] In one embodiment, the interlocking assembly has a first installation direction, in which a first guide slope is connected to the side of the second sidewall adjacent to the first lock, and the first guide slope is inclined relative to the first installation direction.

[0010] In one embodiment, the interlocking assembly has a second installation direction, in which two opposite sides of the second sidewall are respectively connected to a second guide slope, and the second guide slope is inclined relative to the second installation direction.

[0011] In one embodiment, the inner sidewall of the mounting groove is provided with one of a limiting protrusion or a limiting groove, and the second sidewall is provided with the other of a limiting protrusion or a limiting groove. Both the limiting protrusion and the limiting groove extend along the second mounting direction, and the limiting protrusion is engaged in the limiting groove.

[0012] An embodiment of this application also proposes a photovoltaic power station, which includes photovoltaic modules and interlocking components. The interlocking components are those described above, and the interlocking components connect two adjacent photovoltaic modules to the sidewalls of the frame parallel to the corrugations of the color steel sheet.

[0013] In one embodiment, the interlocking assembly has a height direction, and the side wall of the frame of the photovoltaic module parallel to the corrugations of the color steel sheet has two fixing bosses, which are arranged opposite to each other in the height direction; the first lock has a first mounting surface facing the photovoltaic module, and the second lock has a second mounting surface facing the photovoltaic module, and the first mounting surface and / or the second mounting surface has two fixing slots, which are arranged opposite to each other in the height direction; the two fixing bosses are respectively engaged in the two fixing slots.

[0014] In one embodiment, the photovoltaic power station further includes a pad, which is disposed below the frame of the photovoltaic module and the corrugated steel sheet, and is used to support the photovoltaic module.

[0015] In the various embodiments provided in this application, an interlocking assembly is set between two adjacent photovoltaic modules. A first lock is connected to the side wall of the frame of one photovoltaic module, and a second lock is connected to the side wall of the frame of another adjacent photovoltaic module. The second lock is inserted into the mounting groove of the first lock, and fasteners are inserted into the first connecting hole of the first side wall and the second connecting hole of the second side wall. The fasteners connect the first lock and the second lock to achieve the interlocking installation of the interlocking assembly. Thus, the two adjacent photovoltaic modules can be connected to form a whole by the interlocking assembly, which effectively enhances the overall structural strength of the photovoltaic module and enables the photovoltaic module to be stepped on. This helps to reduce the number of maintenance steps in the photovoltaic power station, reduce the construction cost of the photovoltaic power station, and achieve a larger installation area for photovoltaic modules, thereby improving the practicality and reliability of the interlocking assembly.

[0022] In related technologies, photovoltaic (PV) modules can be installed and fixed onto corrugated steel roofs using clamps, clamps, and other mounting components. This ensures the PV modules are stably positioned on the roof, facing the light source, and guarantees the stable conversion of solar energy by the PV system. However, most rooftop PV modules do not meet the requirement of being walkable. Maintenance platforms are typically installed next to the PV modules for users to walk on for cleaning or maintenance. However, installing maintenance platforms increases the construction cost of PV power stations and also occupies roof space, affecting the area where the PV modules can be installed.

[0023] It should be noted that corrugated steel roofing can be used for the roof of a building or other walls. The roof can be formed by sequentially splicing the corrugated steel sheets. In existing photovoltaic power stations, photovoltaic modules are mostly installed independently on the roof using clamps, clamps, and other mounting components. These mounting components can be connected to the corrugated steel sheets to fix and support the photovoltaic modules, allowing multiple modules to be arranged sequentially on the corrugated steel roof. However, the mounting components are spaced at intervals along with the corrugated steel sheets on the photovoltaic modules. This can lead to cantilevered areas at the edges of the photovoltaic modules without support, resulting in lower structural strength and making the modules unable to meet the structural strength requirements for being stepped on. Therefore, to facilitate regular cleaning or maintenance of the photovoltaic modules on the roof, maintenance platforms are usually installed next to the modules, allowing users to move on these platforms to perform cleaning or maintenance work. The installation of maintenance ramps increases the amount of building materials required for photovoltaic (PV) systems, thus raising construction costs. Furthermore, these ramps occupy installation space, impacting the area where PV modules can be installed and resulting in a lower rooftop installation rate. To address these issues, this application proposes an interlocking component 100.

[0024] Please see Figure 1 , Figure 2 and Figure 4In one embodiment of this application, the interlocking assembly 100 includes a first lock 10, a second lock 30, and a fastener 50. The first lock 10 has a mounting groove 13 and two opposing first sidewalls 11, each with a first connecting hole 111 communicating with the mounting groove 13. The second lock 30 can be inserted into the mounting groove 13 and has two opposing second sidewalls 31, each with a second connecting hole 311. The fastener 50 is inserted into the first connecting hole 111 and the second connecting hole 311 and connects the first lock 10 and the second lock 30. The first lock 10 is used to connect a sidewall of a photovoltaic module 200 parallel to the corrugated 41 of a color steel tile 400, and the second lock 30 is used to connect another adjacent sidewall of a photovoltaic module 200 parallel to the corrugated 41 of a color steel tile 400.

[0025] In this application, the photovoltaic power station can install the interlocking component 100 between adjacent photovoltaic modules 200. Specifically, the interlocking component 100 can be installed between the sidewalls of the frame parallel to the corrugations 41 of the corrugated steel sheet 400 and the two adjacent photovoltaic modules 200. By using the interlocking component 100 to connect and lock the two adjacent photovoltaic modules 200, multiple photovoltaic modules 200 arranged in a row can be connected to form a whole. The cantilever at the edge of the adjacent photovoltaic modules 200 can be supported by the interlocking component 100, which effectively enhances the overall structural strength of the photovoltaic modules 200, so that the photovoltaic modules 200 can better meet the function of being stepped on, and at the same time enhance the overall wind resistance of the photovoltaic modules 200.

[0026] The interlocking assembly 100 can connect and fix the first lock 10 to the side wall of the frame of one photovoltaic module 200, and connect and fix the second lock 30 to the side wall of the frame of another adjacent photovoltaic module 200. During the assembly of the photovoltaic power station, when two adjacent photovoltaic modules 200 are arranged and installed, the second lock 30 is inserted into the mounting groove 13 of the first lock 10, and the first connecting hole 111 on the first side wall 11 of the first lock 10 is connected to the second connecting hole 311 on the second side wall 31 of the second lock 30. By inserting the fastener 50 into the first connecting hole 111 and the second connecting hole 311, the fastener 50 locks the first lock 10 and the second lock 30. Thus, under the action of the interlocking assembly 100, the interlocking connection of the two adjacent photovoltaic modules 200 is realized, and the overall assembly of the photovoltaic module 200 is achieved.

[0027] The first lock 10 has two opposite first sidewalls 11 each provided with a first connecting hole 111, and the second lock 30 has two opposite second sidewalls 31 each provided with a second connecting hole 311. When the second lock 30 is inserted into the mounting slot 13 of the first lock 10, the first connecting hole 111 on one first sidewall 11 is connected to the second connecting hole 311 on one second sidewall 31, and the first connecting hole 111 on the other first sidewall 11 is connected to the second connecting hole 311 on the other second sidewall 31. At this point, the interlocking assembly 100 can utilize a fastener 50 that passes through the first lock 10 and the second lock 30, with the fastener 50 inserted into the first connecting holes 111 and 311 on opposite sides of the first lock 10 and the second lock 30; alternatively, the interlocking assembly 100 can utilize two fasteners 50 respectively positioned on opposite sides of the first lock 10 and the second lock 30, with one fastener 50 inserted into the first connecting hole 111 and 311 on one side of the first lock 10 and the second lock 30, and the other fastener 50 inserted into the first connecting hole 111 and 311 on the other side of the first lock 10 and the second lock 30. Furthermore, by utilizing the locking connection between the first lock 10 and the second lock 30 on both sides, a more stable connection and installation of the interlocking assembly 100 can be achieved, ensuring the overall connection stability and reliability of the photovoltaic module 200, and better improving the overall structural strength of the photovoltaic module 200.

[0028] By using the interlocking component 100 to connect the cantilevered structures of two adjacent photovoltaic modules 200, the two adjacent photovoltaic modules 200 can cooperate in bearing the force, which enhances the overall structural strength of the photovoltaic modules 200. This allows the photovoltaic modules 200 to meet the structural strength requirements for being stepped on, thereby reducing the need for maintenance steps in the photovoltaic power station, thus reducing the construction cost of the photovoltaic power station. At the same time, it can reduce the impact of maintenance steps on the installation space of the photovoltaic modules 200, allowing the photovoltaic modules 200 to be fully installed on the roof or roof surface, enabling the photovoltaic power station to achieve higher power generation, and effectively improving the practicality and reliability of the interlocking component 100.

[0029] It should be noted that both the first lock 10 and the second lock 30 can be connected and fixed to the side wall of the photovoltaic module 200 using fastening structures such as screws, bolts, and clips. This application does not limit the connection and fixing method of the first lock 10 and the second lock 30 on the photovoltaic module 200. The fastener 50 can use fastening structures such as pins and bolts, or it can use a pin structure with a certain elasticity to facilitate the assembly of the first lock 10 and the second lock 30. This application does not limit the structural form of the fastener 50, as long as it can achieve a stable locking of the first lock 10 and the second lock 30.

[0030] In one embodiment of this application, an interlocking assembly 100 is provided between two adjacent photovoltaic modules 200. A first lock 10 is connected to the side wall of the frame of one photovoltaic module 200, and a second lock 30 is connected to the side wall of the frame of another adjacent photovoltaic module 200. The second lock 30 is inserted into the mounting groove 13 of the first lock 10, and a fastener 50 is inserted into the first connecting hole 111 of the first side wall 11 and the second connecting hole 311 of the second side wall 31. The fastener 50 connects the first lock 10 and the second lock 30 to achieve the interlocking installation of the interlocking assembly 100. Thus, the interlocking assembly 100 can be used to connect two adjacent photovoltaic modules 200 into a whole, effectively enhancing the overall structural strength of the photovoltaic modules 200. This allows the photovoltaic modules 200 to achieve a step-on function, which helps to reduce the number of maintenance steps in the photovoltaic power station, reduce the construction cost of the photovoltaic power station, and achieve a larger installation area for the photovoltaic modules 200, thereby improving the practicality and reliability of the interlocking assembly 100.

[0031] It should be noted that using materials such as corrugated steel sheets 400 to form the roof of the building allows the photovoltaic modules 200 to be placed directly on the corrugated steel sheets 400, with the bottom surface of the photovoltaic modules 200 in direct contact with the locking edge of the corrugated steel sheets 400. This reduces the bottom clearance of the photovoltaic modules 200 and improves the overall structural strength of the photovoltaic modules 200. Photovoltaic power stations can install the photovoltaic modules 200 horizontally, with the long side of the photovoltaic modules 200 perpendicular to the corrugation 41 of the corrugated steel sheets 400. In this case, the interlocking components 100 can connect the short sides of the frames of two adjacent photovoltaic modules 200, enhancing the overall structural assembly stability and reliability of the photovoltaic modules 200. Alternatively, photovoltaic power stations can also install the photovoltaic modules 200 vertically on the corrugated steel sheet 400 roof or roof surface, with the short side of the photovoltaic modules 200 perpendicular to the corrugation 41 of the corrugated steel sheets 400. In this case, the interlocking components 100 can connect the short sides of the frames of two adjacent photovoltaic modules 200, enhancing the overall structural assembly stability and reliability of the photovoltaic modules 200. Interlocking component 100 connects the long sides of the frames of two adjacent photovoltaic modules 200, enhancing the overall structural assembly stability and reliability of the photovoltaic modules 200. In addition, photovoltaic power plants can also use a combination of horizontal and vertical installation of photovoltaic modules 200, so that the installation directions of some photovoltaic modules 200 and other photovoltaic modules 200 are perpendicular. In this case, interlocking component 100 can connect the long side of the frame of one photovoltaic module 200 and the short side of the frame of another photovoltaic module 200 to better enhance the overall structural assembly stability and reliability of the photovoltaic modules 200.

[0032] There can be two, three, four, or other interlocking components 100 between adjacent photovoltaic modules 200. The number of interlocking components 100 between adjacent photovoltaic modules 200 in this application is not limited. Users can set an appropriate number of interlocking components 100 according to the length of the module frame to better improve the overall structural strength of the photovoltaic module 200.

[0033] See Figure 6 and Figure 8 In one embodiment of this application, the interlocking assembly 100 has a height direction. A first sidewall 11 has a plurality of first connection holes 111 arranged along the height direction, into which a fastener 50 can be inserted. And / or, a second sidewall 31 has a plurality of second connection holes 311 arranged along the height direction, into which a fastener 50 can be inserted.

[0034] It is understandable that, since roofs or roofs constructed with materials such as corrugated steel sheet 400 are usually difficult to ensure the overall flatness of the corrugated sheet 41, the photovoltaic modules 200 installed on the roof or roof may be misaligned in the height direction of two adjacent photovoltaic modules 200. This height direction can be the thickness direction of the photovoltaic module 200, resulting in a certain installation height difference between two adjacent photovoltaic modules 200.

[0035] Therefore, in some embodiments of this application, the first lock 10 may have a plurality of first connecting holes 111 arranged along the height direction on the first sidewall 11. Using these multiple first connecting holes 111, when there is a height difference between two adjacent photovoltaic modules 200, one of the first connecting holes 111 can be connected to a corresponding second connecting hole 311. The fastener 50 is then stably passed through the first connecting hole 111 and the second connecting hole 311, achieving a stable connection and assembly of the interlocking assembly 100. Furthermore, the first lock 10 and the second lock 30 can be connected at a certain offset position in the height direction, allowing the interlocking assembly 100 to stably connect two photovoltaic modules 200 with a certain height difference. This facilitates better adaptation of the interlocking assembly 100 to photovoltaic power stations in various installation environments, further improving the practicality and structural reliability of the interlocking assembly 100. Specifically, the first lock 10 may have multiple first connecting holes 111 arranged along the height direction on both opposite sidewalls, ensuring stable dual-sided installation of the first lock 10 and the second lock 30, further improving the overall structural stability and reliability of the interlocking assembly 100.

[0036] In other embodiments, the second lock 30 may have multiple second connecting holes 311 arranged along the height direction on the second sidewall 31. Using these multiple connecting holes 311, when there is a height difference between two adjacent photovoltaic modules 200, the first connecting hole 111 can communicate with a corresponding second connecting hole 311. This allows the fastener 50 to stably pass through the first connecting hole 111 and lock the first lock 10 and the second lock 30 with the corresponding second connecting hole 311, ensuring a stable connection between the interlocking assembly 100 and the two adjacent photovoltaic modules 200. By arranging multiple second connecting holes 311 along the height direction on the second lock 30, the second lock 30 can be installed at a certain offset distance relative to the first lock 10 along the height direction, achieving a staggered connection between the first lock 10 and the second lock 30 in the height direction. This allows the interlocking assembly 100 to be better applied to photovoltaic power plants in various installation environments, further improving the practicality and structural reliability of the interlocking assembly 100. The second lock 30 can have multiple second connecting holes 311 provided along the height direction on both opposite side walls, ensuring stable dual-side installation of the first lock 10 and the second lock 30, and further improving the overall structural stability and reliability of the interlock assembly 100.

[0037] In other embodiments, the interlocking assembly 100 may have a first lock 10 having a plurality of first connecting holes 111 arranged along the height direction on the first side wall 11, and a second lock 30 having a plurality of second connecting holes 311 arranged along the height direction on the second side wall 31. This allows the first lock 10 and the second lock 30 to be stably connected in a staggered manner in the height direction, so that any first connecting hole 111 can be stably connected to any second connecting hole 311. This enables the fastener 50 to stably connect and cooperate with the first connecting holes 111 and the second connecting holes 311 to achieve a stable assembly of the interlocking assembly 100, ensuring the interlocking assembly 100 is adaptable to the installation of photovoltaic modules 200 in various installation environments, and further improving the practicality and reliability of the interlocking assembly 100.

[0038] See Figure 7 In one embodiment of this application, the fastener 50 includes a fixed rod 51, a movable rod 53, and an elastic element 55. The fixed rod 51 is inserted into the first connecting hole 111 and connected to the first lock 10. The fixed rod 51 is provided with a receiving hole. The movable rod 53 is movably inserted through the receiving hole along the axis of the fixed rod 51 and can be inserted into the second connecting hole 311. The elastic element 55 is provided in the receiving hole and connects the fixed rod 51 and the movable rod 53.

[0039] In this embodiment, the movable rod 53 is axially inserted into the receiving hole of the fixed rod 51, and the movable rod 53 and the fixed rod 51 are connected by the elastic element 55. This allows the fastener 50 to adopt a pin structure that can elastically extend and retract along the axis. Thus, the fastener 50 can insert the fixed rod 51 into the first connecting hole 111 and fix the fixed rod 51 to the first lock 10. At this time, the movable rod 53 can extend into the mounting groove 13, and when the movable rod 53 is subjected to a certain axial force, it can compress the elastic element 55 and retract into the receiving hole. Furthermore, when the second lock 30 is inserted into the mounting slot 13, the side wall of the second lock 30 can abut against the end of the movable rod 53 and apply a certain axial force to the movable rod 53, so that the second lock 30 can push the movable rod 53 back to avoid it during the insertion into the mounting slot 13, ensuring that the second lock 30 can be stably inserted into the mounting slot 13 of the first lock 10; when the second lock 30 and the first lock 10 are engaged and connected, so that the second connecting hole 311 on the second lock 30 is relatively connected to the first connecting hole 111, the movable rod 53 loses the pushing force of the second lock 30, and the elastic member 55 can restore the elastic deformation to apply elastic force to the movable rod 53, so that the movable rod 53 can be inserted into the second connecting hole 311, so that the fastener 50 can be stably inserted into the first connecting hole 111 and the second connecting hole 311, ensuring a stable connection between the first lock 10 and the second lock 30.

[0040] By using the elastically retractable fastener 50 to connect the first connecting hole 111 and the second connecting hole 311, the fastener 50 can be pushed forward to avoid installation during the insertion of the second lock 30 into the mounting slot 13. After the second lock 30 is stably inserted into the mounting slot 13, the connection and assembly of the interlock assembly 100 can be completed. This helps to reduce the assembly operation steps of the interlock assembly 100 and further improves the assembly convenience and practicality of the interlock assembly 100.

[0041] In one embodiment of this application, the fixing rod 51 is threadedly connected to the first lock 10.

[0042] In this embodiment, the fastener 50 can have a threaded structure that engages with the outer periphery of the fixing rod 51 and the inner wall of the first connecting hole 111. During the insertion of the fixing rod 51 into the first connecting hole 111, the threaded engagement between the outer periphery of the fixing rod 51 and the inner wall of the first connecting hole 111 achieves a stable connection between the fixing rod 51 and the first lock 10. Alternatively, a fixing cap can be provided at the end of the fixing rod 51 away from the movable rod 53. In this case, a sleeve that engages with the fixing cap can be provided on the first side wall 11 of the first lock 10, and the surfaces of the sleeve and the fixing cap that engage with each other can be threaded. The threaded connection between the fixing cap and the sleeve achieves a stable connection between the fixing rod 51 and the first lock 10. Furthermore, with the fixed rod 51 threadedly connected to the first lock 10, the fixed rod 51 can be stably installed on the first lock 10, which can more stably cause the movable rod 53 to retract and avoid the insertion of the second lock 30, ensuring that the fastener 50 locks the first lock 10 and the second lock 30, and further improving the structural stability and reliability of the interlock assembly 100.

[0043] See Figure 6 and Figure 8 In one embodiment of this application, the interlocking assembly 100 is provided with a first installation direction. In the first installation direction, the side of the second sidewall 31 adjacent to the first lock 10 is connected to a first guide slope 33. The first guide slope 33 is inclined relative to the first installation direction.

[0044] In this embodiment, the interlocking assembly 100 can move and insert the second lock 30 relative to the first lock 10 along a first installation direction. The first installation direction can be a direction perpendicular to the corrugations 41 of the color steel tile 400, that is, along the arrangement direction of multiple photovoltaic modules 200 arranged side by side perpendicular to the corrugations 41 of the color steel tile 400. By setting an inclined first guide slope 33 on the side of the second side wall 31 near the first lock 10, the first guide slope 33 can be used to push the movable rod 53 of the fastener 50 to retract and avoid it more smoothly during the process of inserting the second lock 30 into the mounting groove 13, thereby better reducing the mutual interference between the second lock 30 and the fastener 50 during the process of inserting the second lock 30 into the mounting groove 13, and further improving the assembly convenience of the interlocking assembly 100.

[0045] See Figure 9 and Figure 10 In one embodiment of this application, the interlocking assembly is provided with a second installation direction. In the second installation direction, the two opposite sides of the second sidewall 31 are respectively connected with second guide slopes 35, and the second guide slopes 35 are inclined relative to the second installation direction.

[0046] In this embodiment, the interlocking assembly 100 can move and insert the second lock 30 relative to the first lock 10 along the second installation direction. The second installation direction can be a direction parallel to the corrugated 41 of the color steel tile 400, or it can be the thickness direction of the photovoltaic module 200, that is, the height direction of the interlocking assembly 100. By setting the second guide slope 35 on the opposite sides of the second side wall 31 along the second installation direction, and setting the second guide slope 35 at an angle relative to the second installation direction, the second lock 30 can be inserted into the mounting groove 13 along the second installation direction. During this process, the second guide slope 35 can be used to push the movable rod 53 of the fastener 50 back to avoid it more smoothly, thereby reducing the mutual interference between the second lock 30 and the fastener 50 during the insertion of the second lock 30 into the mounting groove 13 and further improving the assembly convenience of the interlocking assembly 100.

[0047] See Figure 9 and Figure 10 In one embodiment of this application, the inner sidewall of the mounting groove 13 is provided with one of a limiting protrusion 131 or a limiting groove 313, and the second sidewall 31 is provided with the other of a limiting protrusion 131 or a limiting groove 313. Both the limiting protrusion 131 and the limiting groove 313 extend along the second mounting direction, and the limiting protrusion 131 is engaged in the limiting groove 313.

[0048] In this embodiment, the first lock 10 may have a limiting groove 313 extending along the second installation direction on the inner sidewall of the mounting groove 13, and a limiting protrusion 131 extending along the second installation direction on the second sidewall 31 of the second lock 30; or, the first lock 10 may have a limiting protrusion 131 extending along the second installation direction on the inner sidewall of the mounting groove 13, and a limiting groove 313 extending along the second installation direction on the second sidewall 31 of the second lock 30. By making the shape of the limiting protrusion 131 correspond to that of the limiting groove 313, when the second lock 30 is inserted into the mounting groove 13 of the first lock 10 along the second installation direction, the limiting protrusion 131 can be engaged with the limiting groove 313 to achieve limiting assembly of the first lock 10 and the second lock 30, thereby improving the connection stability and reliability of the interlocking assembly 100.

[0049] At this time, the limiting protrusion 131 and the limiting groove 313 extending along the second installation direction are used to achieve the limiting assembly of the first lock 10 and the second lock 30. This helps to guide the insertion and installation of the second lock 30, and allows the limiting protrusion 131 to be stably inserted into the limiting groove 313 along the second installation direction, ensuring the stable assembly of the interlock assembly 100 and further improving the overall structural stability and reliability of the interlock assembly 100.

[0050] This application also proposes a photovoltaic power station, which includes a photovoltaic module 200 and an interlocking module. The specific structure of the interlocking module is as described in the above embodiments. Since this photovoltaic power station adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] See Figure 5 and Figure 8 In one embodiment of this application, the interlocking assembly has a height direction. The sidewall of the frame of the photovoltaic module 200 and the corrugated 41 of the color steel tile 400 is provided with two fixed protrusions 21, which are arranged opposite to each other in the height direction. The first lock 10 is provided with a first mounting surface facing the photovoltaic module 200, and the second lock 30 is provided with a second mounting surface facing the photovoltaic module 200. The first mounting surface and / or the second mounting surface is provided with two fixed slots 40, which are arranged opposite to each other in the height direction. The two fixed protrusions 21 are respectively engaged in the two fixed slots 40.

[0052] In this embodiment, the height direction of the interlocking component can be the thickness direction of the photovoltaic module 200. By setting two fixed protrusions 21 on the side wall of the frame parallel to the corrugated 41 of the color steel tile 400, two fixed slots 40 can be set on the mounting surfaces of the first lock 10 and the second lock 30. The two fixed protrusions 21 are respectively engaged in the fixed slots 40 to achieve a stable connection between the interlocking component and the photovoltaic module 200.

[0053] In some embodiments, the interlocking assembly can provide two opposing fixing slots 40 on the first mounting surface facing the photovoltaic module 200, so that the first lock 10 can engage with the fixing boss 21 of the photovoltaic module 200 using the fixing slots 40, thereby achieving a stable connection and installation between the first lock 10 and the photovoltaic module 200; at this time, the second lock 30 can be connected to another adjacent photovoltaic module 200 using fastening structures such as screws and bolts.

[0054] In other embodiments, the interlocking assembly can provide two opposing fixing slots 40 on the second mounting surface facing the photovoltaic module 200, so that the second lock 30 can engage with the fixing boss 21 of the photovoltaic module 200 using the fixing slots 40, thereby achieving a stable connection between the second lock 30 and the photovoltaic module 200; in this case, the first lock 10 can be connected to another adjacent photovoltaic module 200 using fastening structures such as screws and bolts.

[0055] Alternatively, in other embodiments, the interlocking assembly may have two opposing fixing slots 40 on the first mounting surface facing the photovoltaic module 200, and two opposing fixing slots 40 on the second mounting surface facing the photovoltaic module 200. This allows the first locking device 10 to engage with a fixing boss 21 of one photovoltaic module 200 using the fixing slots 40, and the second locking device 30 to engage with a fixing boss 21 of another adjacent photovoltaic module 200 using the fixing slots 40. By having both the first locking device 10 and the second locking device 30 of the interlocking assembly 100 engage with the fixing boss 21 using the fixing slots 40, the assembly of the interlocking assembly 100 between two adjacent photovoltaic modules 200 can be improved, thus enhancing the ease of assembly of the interlocking assembly 100 on the photovoltaic module 200 and further increasing assembly efficiency.

[0056] See Figure 3 In one embodiment of this application, the photovoltaic power station further includes a pad 300, which is disposed below the frame of the photovoltaic module 200 and the corrugated 41 of the color steel tile 400, and is used to support the photovoltaic module 200.

[0057] It is understandable that when multiple photovoltaic modules 200 are arranged in a direction perpendicular to the corrugations 41 of the corrugated steel sheet 400 to form a whole, the edge of the photovoltaic module 200 located in this whole is not adjacent to other photovoltaic modules 200, which can easily lead to the cantilever at the edge not being well supported. Therefore, by setting up a pad 300 in the photovoltaic power station, the pad 300 can be placed below the cantilever of the edge of the whole formed by the photovoltaic module 200. By installing the pad 300 on the bottom surface of the frame of the corrugated steel sheet 400 that connects the photovoltaic module 200 to the corrugations 41 of the corrugated steel sheet 400, the pad 300 can provide a certain degree of support for the photovoltaic module 200, enhance the overall structural stability and reliability of the photovoltaic module 200, enable the photovoltaic module 200 to achieve better step-proof functionality, and reduce the need for maintenance steps in the photovoltaic power station.

Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
