Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a gap-filling structure and a photovoltaic system. Background Technology

[0002] In photovoltaic systems, especially distributed rooftop photovoltaic systems or building-integrated photovoltaic systems, after the photovoltaic modules are installed, due to various factors such as the arrangement of the modules and the structural design of the building, some areas of the photovoltaic system may be left uncovered, affecting the waterproof performance of the photovoltaic system. Utility Model Content

[0003] The main objective of this application is to propose a gap-filling structure and a photovoltaic system, which aims to fill gaps in the photovoltaic system to improve its waterproof performance.

[0004] To achieve the above objectives, the gap-filling structure proposed in this application includes:

[0005] The border is formed by two first frame strips and two second frame strips that are set opposite to each other.

[0006] The reinforcing member has two ends connected to the two first frame strips respectively; and

[0007] A mask covers the frame and the reinforcement, and the outer periphery of the mask is connected to the frame.

[0008] In one embodiment, the first frame strip is configured as a tubular structure with an opening on one side, the opening side of the first frame strip is located on the inner periphery of the frame, the first frame strip includes a first sidewall, a second sidewall and a third sidewall, the first sidewall and the opening side of the first frame strip are opposite to each other, the second sidewall and the third sidewall are disposed opposite to each other, and the second sidewall is disposed close to the mask.

[0009] The reinforcing member is configured as a tubular structure with an opening on one side, the opening side of the reinforcing member being located on the side opposite to the mask plate, and the end of the reinforcing member having a folded edge on the side near the mask plate, the folded edge being folded in the direction opposite to the mask plate, and the folded edge being connected to the first side wall by a fastener; or, the reinforcing member is configured as a rod, the second side wall having a limiting protrusion on the side opposite to the mask plate, the reinforcing member being engaged between the two limiting protrusions, and the two limiting protrusions being connected by a fastener on the side of the reinforcing member near the third side wall;

[0010] In one embodiment, both the first frame strip and the reinforcing member are configured as rectangular tubes. The port of the reinforcing member has a connecting protrusion. The port of the reinforcing member abuts against the first frame strip, and the connecting protrusion abuts against the side of the first frame strip opposite to the mask.

[0011] In one embodiment, when a limiting protrusion is provided on the second sidewall, the limiting protrusion is a flanged structure formed by cutting and folding from the second sidewall.

[0012] In one embodiment, when a limiting protrusion is provided on the second sidewall, the limiting protrusion is distributed in multiple intervals along the length direction of the first frame strip.

[0013] This application also proposes a photovoltaic system comprising multiple rows of photovoltaic modules distributed in a first direction, at least one row of photovoltaic modules having a gap, and the gap being provided with the aforementioned gap-filling structure.

[0014] In one embodiment, the photovoltaic system includes multiple beams extending along a first direction and spaced apart along a second direction, the first direction and the second direction intersecting each other. The beams form a first water channel extending along the first direction. The gap filling structure forms a first water passage gap with the photovoltaic modules in the same row, the first water passage gap being located between two beams.

[0015] A water guide is also provided at the location of the gap. The water guide is located below the gap filling structure and forms a second water guide groove. The second water guide groove corresponds to the first water passage gap. A drain outlet is provided on the side of the second water guide groove, and the drain outlet is located above the first water guide groove.

[0016] In one embodiment, in the second direction, drain outlets are provided on both sides of the second water guide channel, and the two drain outlets are respectively arranged opposite to two adjacent first water guide channels.

[0017] In one embodiment, a second water passage gap is formed between the gap filling structure and the photovoltaic modules in the adjacent row, and the second water guide groove is also provided corresponding to the second water passage gap.

[0018] In one embodiment, the photovoltaic system is further equipped with supports and locking components. Two supports are respectively located on opposite sides of the notch filling structure and installed on the beam. Locking components are correspondingly installed on the two supports, and the two locking components form locking grooves with opposite openings. The opposite sides of the notch filling structure are respectively locked into the locking grooves of the two locking components.

[0019] In one embodiment, the multiple rows of photovoltaic modules include at least one row of first photovoltaic modules and at least one row of second photovoltaic modules. The first photovoltaic modules and the second photovoltaic modules are configured as rectangular structures of the same size. The second direction is the length direction of the first photovoltaic module and the width direction of the second photovoltaic module, respectively. The gap filling structure is arranged in at least the same row as the first photovoltaic modules.

[0020] In one embodiment, the photovoltaic system further includes a connection structure disposed on the adjacent side of the first photovoltaic module and the gap filling structure. The connection structure includes two abutting portions spaced apart in the vertical direction. Each of the two abutting portions has a limiting portion protruding on its opposite side. Both the abutting portions and the limiting portions abut against the sides of the first photovoltaic module and the gap filling structure.

[0021] The gap-filling structure of this application is equivalent to a sealing plate, which can seal and cover the gaps left after the photovoltaic modules are installed in the photovoltaic system. This gap-filling structure provides excellent water-blocking effect, ensuring the waterproof performance of the photovoltaic system. In this technical solution, the frame is formed by two first frame strips and two second frame strips, thus constituting a closed square frame structure. The reinforcement effectively enhances the stability of the overall structure. The frame and reinforcement form a skeleton to support the mask. The mask covers the frame and reinforcement, ensuring that the frame and reinforcement are located on the same side of the mask. When installing this gap-filling structure, by facing the frame and reinforcement downwards, they can be hidden, with only the mask exposed on the sun-facing side. This improves the appearance consistency of the photovoltaic system, with the mask primarily providing the water-blocking effect. Furthermore, the reinforcement and first frame strips can be fixed in various ways to ensure the structural stability of the gap-filling structure, thereby reliably sealing the gap.

[0060] This application proposes a gap-filling structure for use in photovoltaic systems.

[0061] Please see Figure 3 and Figure 4 In one embodiment of this application, the gap filling structure 20 includes a frame 100, a reinforcing member 200, and a mask 300. The frame 100 is formed by two opposing first frame strips 110 and two opposing second frame strips 120. The two ends of the reinforcing member 200 are respectively connected to the two first frame strips 110. The mask 300 covers the frame 100 and the reinforcing member 200, and the outer periphery of the mask 300 is connected to the frame.

[0062] Please refer to Figure 1 and Figure 2The gap filling structure 20 of this application is equivalent to a sealing plate, which can seal and cover the gap 13 left after the photovoltaic module 10 is installed in the photovoltaic system. Thus, the gap filling structure 20 can play a good water-blocking role to ensure the waterproof performance of the photovoltaic system. In the technical solution of this application, the frame 100 is formed by two first frame strips 110 and two second frame strips 120, thus forming a closed square frame structure. The setting of the reinforcing member 200 effectively enhances the stability of the overall structure. The frame 100 and the reinforcing member 200 form a skeleton to support the cover plate 300. The cover plate 300 covers the frame 100 and the reinforcing member 200, so that the frame 100 and the reinforcing member 200 are located on the same side of the cover plate 300. When installing the gap filling structure 20, by making the frame 100 and the reinforcing member 200 face downward, the frame 100 and the reinforcing member 200 can be hidden, and only the cover plate 300 is exposed on the sun-facing side, which is conducive to improving the appearance consistency of the photovoltaic system. The cover plate 300 mainly plays the role of water blocking.

[0063] The reinforcing member 200 can be arranged parallel to the second frame strip 120, or it can be arranged at an angle relative to the second frame strip 120. In addition, the mask 300 can be processed by spraying, electroplating and other processes to make the appearance of the mask 300 consistent with the photovoltaic module 10, thereby ensuring the appearance consistency of the photovoltaic system.

[0064] In one embodiment, please refer to Figure 5 and Figure 6 The first frame strip 110 is configured as a tubular structure with an opening on one side. The open side of the first frame strip 110 is located on the inner periphery of the frame 100. The first frame strip 110 includes a first sidewall 111, a second sidewall 112, and a third sidewall 113. The first sidewall 111 is opposite to the open side of the first frame strip 110, and the second sidewall 112 and the third sidewall 113 are opposite to each other. The second sidewall 112 is located close to the mask 300. In this way, the first sidewall 111 can cover the outer periphery of the mask 300 to increase the connection area between the mask 300 and the frame 100, thereby ensuring the connection stability between the mask 300 and the frame 100. The mask 300 is applied to the side where the second sidewall 112 is located. To enhance the connection strength between the mask 300 and the frame strip 101 (first frame strip 110 or second frame strip 120), the mask 300 can sequentially cover the first sidewall 111 and the third sidewall 113. The reinforcing member 200 can be inserted from the open side of the first frame strip 110. Furthermore, the second frame strip 110 can also refer to the structure of the first frame strip 110 and be configured as a tubular structure with its open side located on the inner periphery of the frame 100.

[0065] In one embodiment, please refer to Figure 5Both the first frame strip 110 and the second frame strip 120 have beveled joints 102 at their ends, which are aligned. This maximizes the use of material to form a closed frame structure, reducing material consumption and saving costs. Adjacent frame strips 101 can be fixed together by welding or bonding. The beveled joints 102 allow for welding at the joint, improving ease of operation.

[0066] In one embodiment, please refer to Figure 6 The ends of the first frame strip 110 and the second frame strip 120 are interlocked. That is, in the first frame strip 110 and the second frame strip 120, one is inserted from the open side of the other and fixed by welding, bonding, or fastener 410. This interlocking fit reduces the precision requirements for the processing of the frame strip 101. When both the first frame strip 110 and the second frame strip 120 are open on one side, they have a certain degree of deformation capability, allowing for convenient and reliable interlocking. Furthermore, this structure forms a relatively tight closed structure at the joint, effectively improving the deformation resistance and structural strength of the frame 100.

[0067] In one embodiment, please refer to Figure 7 The reinforcing member 200 is configured as a tubular structure with an opening on one side, the opening side of which is located away from the cover plate 300. In this way, the reinforcing member 200 can stably support the cover plate 300 through the sidewall structure opposite the opening side. Simultaneously, due to the default setting of the opening side, material usage is saved, the weight of the notch filling structure 20 is reduced, and installation is facilitated. The reinforcing member 200 is inserted into the opening side of the first frame strip 110, allowing for a relatively large contact area with the sidewall of the first frame strip 110, thus ensuring the connection stability between the reinforcing member 200 and the first frame strip 110.

[0068] In one embodiment, please refer to Figure 11 and Figure 12 The end of the reinforcing member 200 has a folded edge 201 on the side near the mask 300. The folded edge 201 is folded away from the mask 300 and is connected to the first side wall 111 by a fastener 410. In this way, the folded edge 201 and the first side wall 111 can be fastened together by the fastener 410 to ensure the connection stability between the reinforcing member 200 and the first frame strip 110.

[0069] Among them, fastener 410 can be Figure 11 The self-tapping screws shown Figure 12 The bolt and nut assembly shown. Of course, fastener 410 can also be a rivet or a pin.

[0070] When the fastener 410 is a self-tapping screw, pre-machined holes can be made on the first sidewall 111 to facilitate the alignment of the reinforcing member 200 and reduce the difficulty of driving the self-tapping screw in, thus facilitating operation. Alternatively, neither the first sidewall 111 nor the flange 201 can be drilled. When the fastener 410 is a bolt and nut assembly, the nut can be located on the side of the flange 201 or on the side of the first sidewall 111. Furthermore, when holes are provided on the first sidewall 111 for the fastener 410 to pass through, multiple holes can be distributed at intervals along the length of the first frame strip 110, allowing the reinforcing member 200 to be aligned with one of the multiple holes to facilitate adjustment of the position of the reinforcing member 200 connected to the first frame strip 110.

[0071] In one embodiment, please refer to Figure 13 and Figure 14 The reinforcing member 200 is configured as a rod. The second sidewall 112 has a limiting protrusion 420 on the side facing away from the mask 300. The reinforcing member 200 engages between the two limiting protrusions 420. On the side of the reinforcing member 200 near the third sidewall 113, the two limiting protrusions 420 are connected by fasteners 410. The reinforcing member 200 can be a round rod or other rod-shaped structure. In this embodiment, the reinforcing member 200 is limited between the fasteners 410 and the second sidewall 112, allowing it to be close to the mask 300 and ensuring support for it. The two limiting protrusions 420 limit the reinforcing member 200 on opposite sides, and the second sidewall 112 and fasteners 410 also limit it on the other two sides, effectively surrounding the reinforcing member 200 and fixing it to the first frame strip 110.

[0072] Furthermore, the limiting protrusion 420 is a flanged structure formed by cutting and folding from the second sidewall 112. Specifically, the limiting protrusion 420 is formed by punching the second sidewall 112. This facilitates the processing and forming of the limiting protrusion 420, and by using the second sidewall 112 to form the limiting protrusion 420, material usage can be saved, thereby reducing costs. Of course, in other embodiments, the limiting protrusion 420 may also be erected on the complete second sidewall 112.

[0073] Furthermore, multiple limiting protrusions 420 are distributed at intervals along the length direction of the first frame strip 110. Specifically, multiple pairs of limiting protrusions 420 are distributed at intervals along the length direction of the first frame strip 110, and a space for the reinforcement member 200 is formed between each pair of limiting protrusions 420. The reinforcement member 200 can be installed in one of the multiple pairs of limiting protrusions 420 to facilitate adjustment of the fixed position of the reinforcement member 200 and the first frame strip 110. When multiple reinforcement members 200 are also provided, the number of limiting structures should be greater than the number of reinforcement members 200, so as to provide space for adjusting the installation position of the reinforcement member 200. Of course, it is also possible that a space for the reinforcement member 200 is formed between every two adjacent limiting protrusions 420.

[0074] In other embodiments, the reinforcing member 200 can also be connected to the first frame strip 110 by welding. Welding is a very reliable method, which helps to ensure the connection stability between the reinforcing member 200 and the first frame strip 110.

[0075] In one embodiment, please refer to Figures 8 to 10 The first frame strip 110 is configured as a rectangular tube. In this way, the first frame strip 110 itself forms a circumferentially closed structure, which helps to ensure the structural strength of the first frame strip 110. The second frame strip 120 can also be configured as a rectangular tube. When the first frame strip 110 and the second frame strip 120 are connected, one end is abutted against the side wall of the other, and then fixed by welding, bonding or fastener connection.

[0076] Furthermore, the reinforcing member 200 is configured as a rectangular tube. This creates a circumferentially closed structure for the reinforcing member 200, which helps ensure its structural strength. The end of the reinforcing member 200 abuts against the side wall of the first frame strip 110, and a connecting protrusion 202 protrudes from the end of the reinforcing member 200. This connecting protrusion 202 abuts against the side of the first frame strip 110 opposite to the mask plate 300, thereby increasing the connection area between the reinforcing member 200 and the first frame strip 110, thus ensuring the stability of their connection.

[0077] The reinforcing member 200 not only strengthens the structural strength of the aforementioned sealing plate but also provides space for adjusting its size. The placement of the reinforcing member 200 can be determined based on the number and arrangement of the photovoltaic modules 10 in the photovoltaic system. During on-site construction, the sealing plate is cut near the reinforcing member 200 according to the actual situation, retaining the required portion to fit the size of the notch 13. In the cut portion, the reinforcing member 200 acts as a frame structure on one side, ensuring structural stability after cutting. Furthermore, to enhance the structural stability of the cut portion, the edge of the covering plate 300 can be wrapped around the reinforcing member 200, and the two can be fixed together by welding or bonding.

[0078] In one embodiment, please refer to Figure 4 Multiple reinforcing members 200 are distributed at intervals along the length of the first frame strip 110. This is more conducive to ensuring the structural strength of the notch filling structure 20, and the notch filling structure 20 can be cut at multiple locations to more flexibly adapt to the size of the notch 13.

[0079] In one embodiment, the mask 300 is connected to the frame strip 101 by welding. This achieves a strong bond between the two, improves the overall structure's sealing and stability, effectively prevents the infiltration of external moisture and dust, and enhances the strength and durability of the connection, ensuring the service life of the gap filling structure 20. In other embodiments, the two can also be connected by adhesive or fasteners 410 such as pneumatic nails.

[0080] Provided that strength requirements are met, the frame 100, reinforcing member 200, and mask 300 can be made of metal or plastic. The metal material can be steel or aluminum alloy. It is understood that the first frame strip 110 and the second frame strip 120 of the frame 100 can be the same shape or different shapes, and can be made of the same material or different materials.

[0081] This application also proposes a photovoltaic system; please refer to [link / reference needed]. Figure 1 and Figure 2 The photovoltaic system includes multiple rows of photovoltaic modules 10 distributed in a first direction. At least one row of photovoltaic modules 10 has a notch 13. A notch filling structure 20 is provided at the position of the notch 13. The specific structure of the notch filling structure 20 is as described in the above embodiments. Since this photovoltaic system 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.

[0082] In one embodiment, please refer to Figure 1 and Figure 2 The multi-row photovoltaic module 10 includes at least one row of first photovoltaic module 11 and at least one row of second photovoltaic module 12. The first photovoltaic module 11 and the second photovoltaic module 12 are configured as rectangular structures of the same size. The second direction is the length direction of the first photovoltaic module 11 and the width direction of the second photovoltaic module 12, respectively. The gap filling structure 20 is arranged in the same row as the first photovoltaic module 11 at least.

[0083] It is understood that in photovoltaic systems, the first direction is generally referred to as vertical and the second direction as horizontal. In this embodiment, photovoltaic modules 10 of the same specification are arranged in a mixed manner of horizontal and vertical arrangement. Specifically, for the first photovoltaic module 11, its length direction and arrangement direction are both the second direction, which is a horizontal arrangement, i.e., a horizontal row; for the second photovoltaic module 12, its length direction is the first direction, which is the same as the vertical direction, which is a vertical arrangement, i.e., a vertical row.

[0084] In this way, the available area can be utilized more effectively, maximizing the number of photovoltaic modules 10 installed. At the same time, the standardized specifications of photovoltaic modules 10 can simplify supply chain management, reduce the types and quantities of inventory, and facilitate stocking, replacement and maintenance. Furthermore, the support system, installation method and electrical connection of photovoltaic modules 10 of the same specification can be standardized, which helps to reduce the complexity of on-site construction and improve construction speed and consistency.

[0085] Where the length and width of the photovoltaic module 10 are not integer multiples, a gap 13 will be formed on the side of the first photovoltaic module 11 in a row. This application improves the appearance consistency and waterproof performance of the photovoltaic system by setting a gap filling structure 20 at the position of the gap 13 to cover and seal the gap 13, thus making up for the shortcomings of this arrangement.

[0086] Of course, gaps 13 formed in other locations by the photovoltaic system can also be sealed by the gap filling structure 20.

[0087] In one embodiment, please refer to Figure 15 , Figure 21 and Figure 22 The photovoltaic system includes multiple beams 30 extending along a first direction and spaced apart along a second direction. The first and second directions intersect. The beams 30 form a first water channel 31 extending along the first direction. A first water passage gap 14 is formed between the gap filling structure 20 and the adjacent photovoltaic modules 10 in the same row. The first water passage gap 14 is located between the two beams 30.

[0088] A water guide 40 is also provided at the position of the gap 13. The water guide 40 is located below the gap filling structure 20 and forms a second water guide groove 41. The second water guide groove 41 corresponds to the first water passage gap 14. A drain outlet 42 is provided on the side of the second water guide groove 41. The drain outlet 42 is located above the first water guide groove 31.

[0089] Thus, the first water passage gap 14 is also the vertical gap between the gap filling structure 20 and the photovoltaic modules 10 in the same row. When the first water passage gap 14 is not opposite to the first water guide channel 31, the additional water guide 40 receives the water falling into the first water passage gap 14 and guides the water flow to the first water guide channel 31. The water is then discharged into the first water guide channel 31 through the drain outlet 42, so as to utilize the first water guide channel 31 to concentrate the drainage, which is beneficial to ensuring the waterproof performance of the photovoltaic system.

[0090] Of course, in other embodiments, the gap filling structure 20 can also be tightly connected with the surrounding photovoltaic module 10, that is, without forming a water-passing gap.

[0091] It should be noted that you should refer to [link / reference]. Figure 22 and Figure 23 The gap-filling structure 20 needs to be fixed to the beam 30 by a corresponding installation structure 50. The specific installation structure 50 can refer to the installation structure of the photovoltaic module 10. Specifically, the installation structure 50 includes an installation support 51 and a locking member 52. An installation support 51 is provided on each of the opposite sides of the gap-filling structure 20 within the same first water guide channel 31. The locking member 52 is installed on the installation support 51. The two locking members 52 protrude from the groove of the first water guide channel 31 and form a locking groove 521 with opposite openings. The opposite sides of the gap-filling structure 20 are respectively locked into the locking grooves 521 of the two locking members 52.

[0092] In this embodiment, the supporting force of the beam 30 can be transmitted to the gap filling structure 20 in sequence through the mounting bracket 51 and the locking member 52. The two locking members 52 can limit the gap filling structure 20 in multiple directions. First, the gap filling structure 20 will be clamped between the two locking members 52. Second, the light-facing side and the back-light side of the gap filling structure 20 will be clamped by the two groove walls of the slot 521, which helps to ensure the installation stability of the gap filling structure 20.

[0093] Specifically, when installing the notch filling structure 20, the engaging member 52 can be installed on only one side of the mounting bracket 51 first. In this way, when the side of the notch filling structure 20 is engaged into the slot 521 of the engaging member 52, it will not be interfered with by the other engaging member 52. Then, the other engaging member 52 is installed on the other side of the notch filling structure 20, so that the side of the notch filling structure 20 is engaged into the engaging member 52. Then, the engaging member 52 is installed on the corresponding mounting bracket 51.

[0094] The mounting bracket 51 and the engaging member 52 are respectively provided with mounting holes for the fastener 410 to pass through, so that the mounting bracket 51 and the engaging member 52 are connected by the fastener 410. The mounting hole of at least one of the mounting bracket 51 and the engaging member 52 is a strip hole extending along the first direction, so as to adjust the relative position of the engaging member 52 and the mounting bracket 51 to ensure the installation stability of the notch filling structure 20.

[0095] In other embodiments, the engaging member 52 can also be directly installed inside the first water channel 31.

[0096] Further, please refer to Figure 16 , Figure 24 and Figure 25 On the adjacent sides of the gap filling structure 20 and the first photovoltaic module 11, the two sides can be fixed together by the connection structure 60. The specific connection structure 60 can also refer to the connection structure of the two first photovoltaic modules 11 on the adjacent sides.

[0097] Specifically, the connecting structure 60 includes two abutting portions 61 spaced apart in the vertical direction. Each abutting portion 61 has a limiting portion 62 protruding from its opposite side. Both the abutting portions 61 and the limiting portions 62 abut against the sides of the first photovoltaic module 11 and the gap-filling structure 20. Specifically, the limiting portion 62 abuts against the outer periphery of the first photovoltaic module 11 and the gap-filling structure 20. The two abutting portions 61 abut against the sides of the first photovoltaic module 11 and the gap-filling structure 20 on their respective light-facing and backlighting sides. One abutting portion 61 has a reinforcing portion 63 protruding towards the other abutting portion 61. The reinforcing portion 63 is located in the gap between the first photovoltaic module 11 and the gap-filling structure 20. Fasteners 410 are connected to the two abutting portions 61 and pass through the reinforcing portion 63 to ensure the connection stability of the two abutting portions 61, thereby reliably fixing the adjacent sides of the first photovoltaic module 11 and the gap-filling structure 20.

[0098] In one embodiment, please refer to Figure 15 and Figure 20 In the second direction, drain outlets 42 are provided on both sides of the second water guide channel 41, and the two drain outlets 42 are respectively set opposite to the two adjacent first water guide channels 31. In this way, the drainage efficiency of the second water guide channel 41 can be improved, so that the water in the second water guide channel 41 can be discharged to the first water guide channels 31 on both sides in a timely manner, thereby avoiding excessive water accumulation in the second water guide channel 41 and causing leakage.

[0099] Of course, in other embodiments, the second water guide channel 41 may be provided with a drain outlet 42 on one side. Specifically, the water guide 40 extends from the position opposite to the first water passage gap 14 toward the adjacent beam 30, and a drain outlet 42 is provided on one side opposite to the beam 30.

[0100] In one embodiment, please refer to Figures 17 to 19 A second water-passing gap 15 is formed between the gap-filling structure 20 and the adjacent row of photovoltaic modules 10, and a second water-guiding channel 41 is also correspondingly provided with the second water-passing gap 15. The second water-passing gap 15 is also the lateral gap between the gap-filling structure 20 and the adjacent row of photovoltaic modules 10. In this way, the water-guiding component 40 can also receive water falling into the second water-passing gap 15, so that the water-guiding component 40 can simultaneously play a waterproofing role for both the lateral gap and the vertical gap between the gap-filling structure 20 and other photovoltaic modules 10. There can be one or more second water-passing gaps 15 corresponding to one second water-guiding channel 41. Specifically, the first water-passing gap 14 can be regarded as extending obliquely to the horizontal plane along the first direction, and at least one of its upper end and lower end will meet the second water-passing gap 15. The water-guiding component 40 has a square or near-square structure and is simultaneously provided with respect to the intersecting first water-passing gap 14 and second water-passing gap 15.

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 scope of protection of this application.
