Description

[0002] As a renewable energy source, solar energy has become an important part of human energy use, especially the use of solar energy to generate electricity through photovoltaic modules is becoming more and more widespread.

[0003] Photovoltaic modules are usually installed in open areas. During thunderstorms, photovoltaic power generation systems are more susceptible to lightning strikes. After being struck by lightning, static electricity will accumulate on the photovoltaic modules. It is necessary to install a grounding conductive sheet on the photovoltaic modules to quickly transfer the electricity generated by the lightning strike to the ground in a timely manner to avoid the photovoltaic modules being destroyed.

[0004] In a photovoltaic module, there is a height difference between the photovoltaic panel and the module frame. When the photovoltaic module is tilted, water and dust will accumulate at the module frame at the lower end of the photovoltaic module. After the water evaporates, the remaining dust will form a dust belt, which will block the photovoltaic module and seriously affect the power generation efficiency and power generation of the photovoltaic module. In order to avoid the above problems, a deflector is usually set on the photovoltaic module.

[0049] The photovoltaic power generation system provided by the embodiment of the present application is first described below.

[0050] like Figure 1 As shown, the photovoltaic power generation system provided in the embodiment of the present application includes: a photovoltaic bracket (not shown in the figure), and a photovoltaic component 1 fixed to the photovoltaic bracket.

[0051] The photovoltaic bracket is fixed on the mounting surface.

[0054] like Figure 2 and Figure 3As shown, the photovoltaic module 1 includes a photovoltaic panel 11 and a module frame 12 located outside the photovoltaic panel 11. There is a height difference between the photovoltaic panel 11 and the module frame 12. Water, dust, etc. will accumulate inside the module frame 12 at the lower end of the photovoltaic module 1, that is, there is a water accumulation area inside the module frame 12 at the lower end of the photovoltaic module 1, and the water accumulation area can accumulate water, dust, etc.

[0055] It should be noted that the water accumulated in the water accumulation area may be rainwater or cleaning fluid for cleaning photovoltaic modules.

[0056] like Figure 2 and Figure 3 As shown, the photovoltaic power generation system provided in the embodiment of the present application further includes a flow guide 3 and a pressing block 4. The flow guide 3 is fixed to the photovoltaic support (not shown in the figure) through the pressing block 4.

[0057] It should be noted that the pressing block 4 is a pressing block used to fix the photovoltaic module 1 on the photovoltaic support, and the pressing block 4 can be called a medium pressing block. In this way, the photovoltaic module 1 and the deflector 3 can be fixed by the pressing block 4, which simplifies the installation of the photovoltaic power generation system and improves the installation efficiency of the photovoltaic power generation system.

[0058] In some embodiments, the photovoltaic support may include a clamp 6 and a fastener 5, wherein the clamp 6 is used to be fixed on the mounting surface of the photovoltaic support, and the fastener 5 is used to fix the pressing block 4 and the clamp 6. The fastener 5 may be a bolt or other fasteners.

[0059] The installation method of the above-mentioned deflector 3 is: first pre-install the pressure block 4, the fastener 5, and the clamp 6; then pre-install the deflector 3 on the bottom side of the pressure block 4; then install the deflector 3, the pressure block 4, the fastener 5, and the clamp 6 together, wherein the deflector 3 is placed on the component frame 12, the clamp 6 is installed on the installation surface, the fastener 5 is rotated and tightened, and the deflector 3 is pressed onto the component frame 12 through the pressure block 4, thereby fixing the deflector 3 on the component frame 12.

[0060] In the above embodiment, in order to facilitate the fixed connection between the clamp 6 and the installation surface, the installation surface can be selected as a roof surface, the roof surface is provided with roof tiles 2, and the clamp 6 clamps the roof tiles 2, that is, the clamp 6 is fixed on the roof tiles 2.

[0061] In the embodiment of the present application, the deflector 3 is installed by means of a pressing block 4, a fastener 5 and a clamp 6. Installation and disassembly only require operating the fastener 5, which greatly increases the convenience of operation and can effectively improve the installation efficiency of the photovoltaic power generation system.

[0062] In some other embodiments, the pressing block 4 can be fixed to the photovoltaic support through a connecting assembly, the connecting assembly includes a clamp 6 and a fastener 5, the clamp 6 is fixed to the photovoltaic support, and the fastener 5 is fixed to connect the pressing block 4 and the clamp 6. In this embodiment, the installation method of the deflector 3 can refer to the installation method mentioned above, which will not be repeated here. In this embodiment, the convenience of operation is also improved, which can effectively improve the installation efficiency of the photovoltaic power generation system.

[0063] The deflector of the photovoltaic power generation system provided in the embodiment of the present application, namely the deflector 3 mentioned above, is described in detail below.

[0064] Combination Figure 2-Figure 4 As shown, the guide 3 includes: a crimping piece 31 , a first guide piece 32 , and a second guide piece 35 .

[0065] In the deflector 3, the crimping piece 31 is used to be crimped onto the component frame 12 of the photovoltaic component 1 through the pressing block 4. It should be noted that the crimping piece 31 is crimped onto the component frames 12 of two photovoltaic components 1, a part of the crimping piece 31 is crimped onto the component frame 12 at a lower position in one photovoltaic component 1, and a part of the crimping piece 31 is crimped onto the component frame 12 at a higher position in another photovoltaic component 1. Among them, the component frame 12 at a lower position in one photovoltaic component 1 is higher than the component frame 12 at a higher position in another photovoltaic component 1, that is, the crimping piece 31 is crimped onto two component frames 12 of different heights.

[0066] The crimping piece 31 is crimped onto the component frame 12 to fix the entire deflector 3 .

[0067] In the embodiment of the present application, the crimping sheet 31 is fixed to the bottom side of the pressing block 4. When disassembling, the pressing block 4 is removed and the deflector 3 can be removed, which simplifies the installation and disassembly of the deflector; the crimping sheet 31 is fixed by crimping the pressing block 4, that is, the deflector 3 is fixed by crimping the pressing block 4, which simplifies the installation structure and reduces the installation cost.

[0068] After the guide 3 is installed, there is a gap between the pressing block 4 and the pressing piece 31, which can be called a guide gap 7, and water has a capillary effect in the guide gap 7. The guide gap 7 is connected to the water accumulation area of ​​the photovoltaic module, so that the water in the water accumulation area (the water may be mixed with foreign matter such as dust) can enter the guide gap 7.

[0069] The second guide plate 35 is disposed on the crimping plate 31 . The second guide plate 35 is located at one end of the guide gap 7 . The second guide plate 35 is used to guide the accumulated water in the water accumulation area through the guide gap 7 , and also to discharge the water in the guide gap 7 .

[0070] As mentioned above, a portion of the above-mentioned crimping piece 31 is crimped onto a lower component frame 12 in one photovoltaic component 1, and a portion of the above-mentioned crimping piece 31 is crimped onto a higher component frame 12 in another photovoltaic component 1. Based on this, the second guide plate 35 corresponds to a lower component frame 12 in one photovoltaic component 1.

[0071] In order to facilitate the drainage of the accumulated water, the top end of the second guide plate 35 is located at one end of the guide gap 7 , and the bottom end of the second guide plate 35 is away from the guide gap 7 .

[0072] There may be one or more second guide plates 35. When there are more than two second guide plates 35, any two second guide plates 35 are sequentially distributed along the length direction of the guide gap 7. In this way, the guide effect and guide efficiency are improved.

[0073] It should be noted that the length direction of the guide gap 7 is the length direction of the crimping piece 31 , and is also the length direction of a side of the component frame 12 where the crimping piece 31 is located.

[0074] At least one of the crimping sheet 31 and the second guide sheet 35 is a conductive sheet, which is provided with a piercing structure 38 for piercing the protective film of the pressing block 4 and the component frame 12 to enable electrical conduction between the component frame 12 and the ground.

[0075] In some embodiments, the crimping plate 31 and the second guide plate 35 are both conductive plates. In this way, in the entire guide 3, the second guide plate 35 and the crimping plate 31 are both used to make electrical conduction between the component frame 12 and the ground, thereby improving the conductivity reliability and the conductivity effect.

[0076] It should be noted that, when the photovoltaic bracket includes a fastener 5 and a clamp 6, and the pressing block 4 is fixed to the clamp 6 by the fastener 5, the pressing block 4, the fastener 5 and the clamp 6 are all conductive parts, and the clamp 6 is electrically conductive to the ground. When there is thunderstorm weather, current passes through the surface of the photovoltaic module 1, and the current can be led to the ground through the crimping piece 31, the pressing block 4, the fastener 5 and the clamp 6 in sequence, and / or the current can be led to the ground through the second guide piece 35, the pressing block 4, the fastener 5, the clamp 6 in sequence, and the clamp 6 leads the current to the ground.

[0077] When the pressing block 4 is fixed to the photovoltaic support through the connecting assembly, the pressing block 4, the connecting assembly and the photovoltaic support are all conductive parts, and the photovoltaic support and the ground are electrically conductive. When there is thunderstorm weather, there is current passing through the surface of the photovoltaic assembly 1, and the current can be led to the ground through the crimping piece 31, the pressing block 4, the connecting assembly and the photovoltaic support in sequence, and / or the current can be led to the ground through the second guide piece 35, the pressing block 4, the connecting assembly and the photovoltaic support in sequence.

[0078] In some embodiments, the portion where the crimping sheet 31 contacts the pressing block 4 is provided with an upper puncture structure and a lower puncture structure, the upper puncture structure is used to puncture the protective film of the pressing block 4, and the lower puncture structure is used to puncture the protective film of the component frame 12. It can be understood that the upper puncture structure and the lower puncture structure are both partial structures of the puncture structure 38.

[0079] The portion of the second guide plate 35 in contact with the pressure block 4 is arranged on the puncturing structure 38, and the puncturing structures 38 are distributed on both sides of the second guide plate 35. The puncturing structure 38 on one side is used to puncture the protective film of the pressure block 4, and the puncturing structure 38 on the other side is used to puncture the protective film of the component frame 12.

[0080] The protective film may be an aluminum alloy oxide film or other films, which are not limited in the present embodiment. The puncture structure 38 may be a point puncture in terms of technology, that is, the puncture structure 38 has a puncture angle, which is used to scratch the protective film. Of course, the puncture structure 38 may also be other structures, which are not limited in the present embodiment.

[0081] In the embodiment of the present application, the crimping sheet 31 is installed in cooperation with the pressing block 4. During the process of fixing the pressing block 4, the force of the puncturing structure 38 on the protective film is increased, thereby improving the reliability of the puncturing structure 38 puncturing the protective film. Moreover, the puncturing structure 38 is also provided on the second guide sheet 35, the puncturing point is clear, the puncturing is precise, and the conductive effect can be greatly improved.

[0082] The first guide plate 32 is disposed on the crimping plate 31 . The first guide plate 32 extends from the inside of the component frame 12 to the outside of the component frame 12 . The first guide plate 32 is used to guide the accumulated water out of the water accumulation area.

[0083] As mentioned above, a portion of the above-mentioned crimping piece 31 is crimped onto a lower component frame 12 in one photovoltaic component 1, and a portion of the above-mentioned crimping piece 31 is crimped onto a higher component frame 12 in another photovoltaic component 1. Based on this, the first guide plate 32 corresponds to a lower component frame 12 in one photovoltaic component 1.

[0084] There may be one or two first guide plates 32. When there are two first guide plates 32, the two first guide plates 32 are respectively located at two ends of the crimping plate 31 in the length direction, thus improving the guiding efficiency and guiding effect.

[0085] The specific structure of the first guide plate 32 is selected according to actual conditions. In some embodiments, the first guide plate 32 includes a guide front section 321, a guide middle section 322 and a guide rear section 323 connected in sequence, wherein the guide front section 321 extends into the component frame 12, and the guide rear section 323 is located outside the component frame 12.

[0086] The front diversion section 321 extends to the water accumulation area, and there is a gap between the front diversion section 321 and the photovoltaic module 1. The water in the water accumulation area enters the gap between the front diversion section 321 and the photovoltaic module 1, the gap between the middle diversion section 322 and the photovoltaic module 1 through capillary action, and then reaches the rear diversion section 323. The water is discharged out of the module frame 12 under the action of its own gravity.

[0087] The diversion middle section 322 may be provided with through holes. In the case of excessive rainfall, water may pass through the through holes and flow down the first diversion plate 32 to discharge the component frame 12, thereby increasing the diversion water volume and improving the diversion effect and efficiency.

[0088] In the embodiment of the present application, in the process of draining the water from the water accumulation area, the dust in the water will also be drained out, thereby reducing the formation of dust accumulation belts and improving the power generation efficiency of the photovoltaic module.

[0089] The deflector of the photovoltaic power generation system provided in the embodiment of the present application integrates the diversion function and the conductive function, that is, it realizes the optimized integration of the existing deflector and the existing crimping plate, which can not only improve the formation of the dust accumulation belt but also solve the problem of grounding of the photovoltaic module. The deflector component installed on the photovoltaic module can meet the needs of diversion and ground conduction. Compared with the prior art that requires the installation of two components, the deflector and the crimping plate, the components that need to be installed are reduced, which is more conducive to workers' installation, simplifies the installation of the photovoltaic power generation system, improves the installation efficiency of the photovoltaic power generation system, and saves the installation cost of the photovoltaic power generation system.

[0090] At the same time, in the deflector of the photovoltaic power generation system provided in the embodiment of the present application, the accumulated water in the water accumulation area of ​​the photovoltaic component is discharged through the mutual cooperation of the deflection gap 7 between the crimping plate and the pressing block and the second deflector, and the first deflector, thereby effectively increasing the deflection area, increasing the deflection position, and improving the deflection effect.

[0091] In the embodiment of the present application, the crimping sheet 31 includes: a first crimping portion 311, a second crimping portion 312, and a connecting portion 313; wherein the first crimping portion 311 and the second crimping portion 312 are used to be crimped on the component frames 12 of two photovoltaic components 1, and the first crimping portion 311 is used to be crimped on the lower component frame 12 in one photovoltaic component 1, and the second crimping portion 312 is used to be crimped on the higher component frame 12 in another photovoltaic component 1; the connecting portion 313 connects the two ends of the first crimping portion 311 and the second crimping portion 312 and forms a mounting hole 314 for inserting the pressure block 4.

[0092] It should be noted that there are two connecting parts 313, which are respectively located at the two ends of the first crimping part 311 (the second crimping part 312). In the case where the crimping sheet 31 is a conductive sheet, the first crimping part 311, the second crimping part 312, and the connecting part 313 are all conductive parts, and the piercing structure 38 of the crimping sheet 31 is arranged on the first crimping part 311 and the second crimping part 312.

[0093] In the above-mentioned guide plate 3 , the second guide plate 35 and the first guide plate 32 are both arranged on the first crimping portion 311 , and the second guide plate 35 is located in the mounting hole 314 .

[0094] The above-mentioned guide device 3 has a simple structure, which facilitates the installation of the guide device 3 and the pressing block 4, and also facilitates the second guide plate 35 to guide the water out of the water accumulation area through the guide gap.

[0095] In order to simplify the installation, the crimping piece 31 is an integrated structure, that is, the first crimping portion 311 , the second crimping portion 312 , and the connecting portion 313 are an integrated structure.

[0096] In some other embodiments, the crimping sheet 31 may also be selected to have other structures, which is not limited in this embodiment.

[0097] In the embodiment of the present application, the second guide plate 35 can be arranged along the vertical direction, or can be arranged inclined relative to the vertical direction.

[0098] When the second guide plate 35 is arranged in the vertical direction, the crimping plate 31 is more likely to move during the process of fixing the pressure block 4. In particular, when the pressure block 4 is fixed by tightening the fastener 5, the crimping plate 31 will rotate, which may easily cause the second guide plate 35 to shift and tilt, affecting the second guide plate 35 from guiding and puncturing the protective film.

[0099] In order to avoid the above problems, in some embodiments, the second guide plate 35 is tilted relative to the vertical direction, one end of the second guide plate 35 is a connecting end, the connecting end of the second guide plate 35 is connected to the crimping plate 31, and the other end of the second guide plate 35 is a free end, and the free end of the second guide plate 35 is farther away from the component frame 12 corresponding to the second guide plate 35 than the connecting end of the second guide plate 35.

[0100] In the above embodiment, in the process of fixing the pressing block 4, there is a strong interaction between the second guide plate 35 and the side surface of the pressing block 4. Under the joint limiting action of the pressing block 4 and the component frame 12, the second guide plate 35 is prevented from being offset or skewed, thereby ensuring the guiding effect of the second guide plate 35; due to the strong interaction between the second guide plate 35 and the side surface of the pressing block 4, when the second conductive plate 35 is a conductive plate, the puncture possibility of the puncture structure 38 is guaranteed, thereby enhancing the conductive effect; and the entire deflector 3 is prevented from being offset.

[0101] In some embodiments, the inclination angle of the second guide plate 35 relative to the vertical direction is in the range of 5°-8°. In this way, the second guide plate 35 can be prevented from being deflected and skewed to the greatest extent, and the entire guide 3 can be prevented from being deflected. In actual situations, the above range can also be appropriately adjusted, and the embodiments of the present application do not limit this.

[0102] In the embodiment of the present application, there is a gap between the first guide plate 32 and the crimping plate 31, and the first guide plate 32 is connected to the crimping plate 31 through the connecting plate 36. There is a gap between the connecting plate 36 and the photovoltaic module 1. In this way, foreign matter such as dust flowing through the gap between the first guide plate 32 and the photovoltaic module 1 can enter the gap between the connecting plate 36 and the photovoltaic module 1, reducing the probability of the gap between the first guide plate 32 and the photovoltaic module 1 being blocked by foreign matter such as dust, thereby improving the reliability of the guide.

[0103] The connecting piece 36 may be a curved structure or a folded line structure. In some embodiments, the connecting piece 36 is a folded line structure, that is, the connecting piece 36 is a bent plate, and the bent plate has a step structure, which improves the stability of the deflector 3, thereby reducing the probability of the deflector 3 being damaged and deformed during transportation; at the same time, it also increases the area of ​​the water passage, which is more conducive to drainage when the water volume is large.

[0104] In some other embodiments, the deflector 3 further includes a reinforcing rib 37, which extends from the first deflector 32 to the crimping sheet 31, and the reinforcing rib 37 is fixed to the first deflector 32, the connecting sheet 36 and the crimping sheet 31. In this way, the structural strength of the first deflector 32 and the connecting sheet 36 is improved, and the stability of the entire deflector 3 is improved.

[0105] During the installation of the deflector 3, i.e., during the fixing of the pressing block 4, the pressing block 4 squeezes the crimping sheet 31. Since the thickness of the deflector 3 is relatively thin, the deflector 3 is more likely to be greatly deformed, resulting in the first deflector 32 being warped upward, and the flow guiding performance of the first deflector 32 being weakened, especially when the pressing block 4 is fixed by the fastener 5. In order to avoid the above problems, the crimping sheet 31 can be improved by pre-adding a deformation structure to the crimping sheet 31. Figure 6 As shown, in some embodiments, in the length direction of the crimping sheet 31, the first guide sheet 32 ​​is located at both ends of the crimping sheet 31; the crimping sheet 31 is a curved structure, and the middle part of the length direction of the crimping sheet 31 protrudes toward the top side of the crimping sheet 31. Exemplarily, the crimping sheet 31 is an arc-shaped structure. When the pressing block 4 is pressed down, the curved structure of the crimping sheet 31 can offset the deformation caused by the downward pressure, thereby avoiding the first guide sheet 32 ​​from warping up, and improving the stability of the guide effect of the first guide sheet 32.

[0106] In the embodiment of the present application, the crimping sheet 31 and the first guide sheet 32, the reinforcing rib 37 and other components can be connected by welding. The deformation structure pre-added on the crimping sheet 31 can estimate the direction and shrinkage of the deformation after welding in advance based on the properties of the welded metal. Before welding, the workpiece is pre-deformed by mechanical methods so that the deformation after welding meets the requirements.

[0107] It should be noted that, when the crimping piece 31 includes a first crimping portion 311, a second crimping portion 312 and a connecting portion 313, the first crimping portion 311 and the second crimping portion 312 are both bent structures, and the middle portion of the first crimping portion 311 in the length direction protrudes toward the top side of the crimping piece 31, and the middle portion of the second crimping portion 312 in the length direction protrudes toward the top side of the crimping piece 31.

[0108] like Figure 3-Figure 6 As shown, in some embodiments, the above-mentioned guide 3 also includes a wire clamp, which is arranged on the bottom side of the crimping plate 31, and the wire clamp and the second guide plate 35 are respectively located on both sides of the width direction of the crimping plate 31, and the width direction of the crimping plate 31 is the width direction of the component frame 12; the wire clamp has a wire clamp portion 34, and the wire clamp portion 34 is used to clamp the cable connecting the photovoltaic component 1 and the photovoltaic connector.

[0109] When the crimping piece 31 includes a first crimping portion 311 , a second crimping portion 312 and a connecting portion 313 , the first guide piece 32 and the second guide piece 35 are disposed at the first crimping portion 311 , and the wire clamp is disposed at the second crimping portion 312 .

[0110] The specific structure of the wire clamp and the wire clamp portion 34 is selected according to actual conditions, and this embodiment does not limit this.

[0111] In the above embodiment, after the deflector 3 is installed, the cables connecting the photovoltaic component 1 and the photovoltaic connector can be placed in the wire clamp portion 34, which plays a role in arranging and fixing the cables, avoiding the cables from being scattered around, thereby avoiding the scattered cables from being immersed in water and affecting the power generation of the photovoltaic component 1; it also avoids the operation and maintenance personnel from kicking the cables off, eliminating the safety risks caused by the cables being kicked off, avoiding affecting the power generation of the photovoltaic component 1, and improving safety and reliability.

[0112] The cable may be an MC4 terminal connection cable, where MC is the abbreviation of Multi-Contact, and MC refers to the Swiss Electric Connector Company; 4 is the size standard of the metal core diameter. Of course, the cable may also be of other types, which is not limited in the present embodiment of the application.

[0113] In the above embodiment, the functions of the existing deflector, the existing crimping sheet and the wire clamp are optimized and integrated into one structural member (deflector 3), which has a simple structure and is more convenient for workers to install, thereby improving installation efficiency and saving installation costs.

[0114] like Figure 3-Figure 5 As shown, in some embodiments, the above-mentioned deflector 3 also includes a supporting member; wherein; the supporting member is arranged on the bottom side of the crimping plate 31, and the supporting member and the second deflector 35 are respectively located on both sides of the width direction of the crimping plate 31, and the width direction of the crimping plate 31 is the width direction of the component frame 12; the supporting member has a supporting portion 33, and the supporting portion 33 is used to support the bottom side of the component frame 12.

[0115] As mentioned above, a portion of the crimping piece 31 is crimped onto a lower component frame 12 in one photovoltaic component 1, and a portion of the crimping piece 31 is crimped onto a higher component frame 12 in another photovoltaic component 1. Based on this, the supporting portion 33 is used to support the higher component frame 12 in another photovoltaic component 1.

[0116] In the above embodiment, the supporting portion 33 supports the assembly frame 12, so that the deflector 3 and the assembly frame 12 are mutually limited in the vertical direction, thereby avoiding the deflector 3 from shifting up and down before and during installation.

[0117] The specific structure of the supporting member and the supporting portion 33 is selected according to actual conditions. For example, the supporting portion 33 is L-shaped, which is not limited in this embodiment.

[0118] In some other embodiments, the deflector 3 includes a wire clamp and a supporting member. The specific structures of the wire clamp and the supporting member are referred to above and will not be described again here.

[0119] In the above embodiment, in order to simplify the structure and installation, the wire clamp and the supporting member are an integrated structure. Of course, the wire clamp and the supporting member can be a split structure.

[0120] In the above embodiment, in order to facilitate installation of the deflector 3 and wire fixing, the supporting portion 33 can be selected to be located on the top side of the wire clamp portion 34. Of course, the supporting portion 33 and the wire clamp portion 34 can also be selected to be distributed in other directions, which is not limited in this embodiment.

[0121] like Figure 7 As shown, the contact surface between the pressing block 4 and the crimping sheet 31 is provided with a first concave-convex structure 41, and the first concave-convex structure 41 is used to increase the roughness of the above-mentioned contact surface, thereby increasing the force between the pressing block 4 and the crimping sheet 31 and improving the stability of the deflector 3; the first concave-convex structure 41 also ensures that a guide gap 7 is formed between the pressing block 4 and the crimping sheet 31, thereby facilitating the formation of the guide gap 7 and improving the guide effect.

[0122] Exemplarily, the first concave-convex structure 41 includes a protrusion and a concave portion, wherein a concave portion may be formed between two adjacent protrusions, and a protrusion may be formed between two adjacent concave portions. The protrusion may be tooth-shaped or dot-shaped. The first concave-convex structure 41 may also be other structures, as long as the roughness of the above-mentioned contact surface can be increased, and the embodiment of the present application does not limit this.

[0123] In actual situations, the contact surface between the crimping sheet 31 and the pressing block 4 may be provided with a second concave-convex structure, which is used to increase the roughness of the contact surface between the crimping sheet 31 and the pressing block 4 and to ensure that a flow guide gap 7 is formed between the pressing block 4 and the crimping sheet 31. For the specific structure of the second concave-convex structure, reference may be made to the first concave-convex structure 41, which will not be described in detail here.

[0124] In the embodiment of the present application, the first concave-convex structure 41 and the second concave-convex structure can be provided at the same time or separately, depending on the actual situation.

[0125] Since the above-mentioned deflector 3 has the above-mentioned technical effects, the photovoltaic power generation system provided in the embodiment of the present application includes the above-mentioned deflector 3, and the photovoltaic power generation system provided in the embodiment of the present application also has the corresponding technical effects, which will not be repeated here.

[0126] The technical features mentioned above and the technical features shown individually in the drawings can be combined with each other arbitrarily, as long as the combined technical features are not contradictory.
