Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and more specifically, to a water guide for a photovoltaic assembly and a photovoltaic module. Background Art

[0002] In a photovoltaic power station, the frame of the photovoltaic module is higher than the encapsulating glass of the photovoltaic module. If the photovoltaic module is tilted at a small angle, the lowest point of the encapsulating glass surface will be at the module frame, where water will accumulate. This water will have an adverse effect on the photovoltaic module. Therefore, the accumulated water needs to be drained.

[0003] At present, accumulated water is mainly discharged by installing water guides on photovoltaic modules. However, the diversion cross-section of the diversion channel formed between the water guide and the photovoltaic module is easily blocked by foreign matter such as particles and dust on the surface of the photovoltaic module, resulting in slow drainage or even drainage failure.

[0004] In addition, the water guide is fixed by a mounting plate and fasteners, which makes the installation more complicated and the installation efficiency is low.

[0082] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0083] like Figure 1-5 、 Figure 8-13 、 Figure 17-22 、 Figures 27-29 As shown, the water deflector for a photovoltaic module provided in an embodiment of the present invention includes: a fixing portion 110, at least one water deflector 120, and a first transition portion 130. The fixing portion 110 is fixed to the water deflector mounting location; the water deflector 120 is configured to form a flow channel b with the photovoltaic module 200; and the first transition portion 130 connects the fixing portion 110 and an adjacent water deflector 120 to form a first gap a between the fixing portion 110 and the adjacent water deflector 120.

[0084] It is understood that a predetermined distance exists between the first transition portion 130 and the photovoltaic module 200, and this predetermined distance is greater than zero to prevent the first transition portion 130 from obstructing the first gap a. This ensures that the first gap a is open in the flow-guiding direction of the flow-guiding channel b. Specifically, in the flow-guiding direction, one end of the first gap a is open, the other end of the first gap a is also open, and the first gap a is conductive in the flow-guiding direction.

[0085] The water guide installation position is the location where the water guide for the photovoltaic module needs to be installed and fixed. Figure 7 、 Figure 12 、 Figure 14 、 Figure 15 、 Figure 18 、 Figure 20 、 Figure 22 and Figure 28 As shown, the water guide installation position can be selected to be distributed on the component frame 210 of the photovoltaic component 200; Figure 23 and Figure 24As shown, the photovoltaic module 200 can also be fixed to the module support device 300, and the water guide installation positions are distributed on the module support device 300; Figure 25 and Figure 26 As shown, the photovoltaic component 200 is fixed to the component support device 300, the component support device 300 is fixed on the bearing surface 400, the water guide installation positions are distributed on the bearing surface 400, and the bearing surface 400 is the supporting surface of the roof surface, the ground or the floating device.

[0086] The specific structure of the component bracket device 300 is selected according to actual needs and is not limited in this embodiment.

[0087] The water guide for the photovoltaic module provided in the above embodiment is provided with a fixed part 110, a water guide part 120 and a first transition part 130, and the first transition part 130 is used to connect the water guide part 120 and the fixed part 110 so that a first gap a is provided between the water guide part 120 and the fixed part 110, thereby effectively avoiding the formation of a dead angle between the fixed part 110 and the first transition part 130, thereby avoiding the accumulation of foreign matter such as particles and dust on the surface of the photovoltaic module 200 and the blockage of the guide channel b, thereby improving the water guide performance.

[0088] In the above photovoltaic module water guide, there are many distribution modes of the fixing portion 110, the first transition portion 130 and the water guide portion 120. In one embodiment of the present application, Figure 1-5 、 Figure 8-13 and Figure 29 As shown, the fixing portion 110, the first transition portion 130 and the water guide portion 120 are distributed along the diversion width direction of the water guide portion 120. It can be understood that the diversion width direction of the water guide portion 120 is Figure 5 、 Figure 8 、 Figure 9 The fixing portion 110, the first transition portion 130 and the water guide portion 120 are used to be distributed along the horizontal side of the component frame 210, such as Figure 6 shown.

[0089] With the above distribution method, the number of the fixing parts 110 may be one or more than two, which can be selected based on actual needs.

[0090] Using the above distribution method, such as Figure 7 、 Figure 12 、 Figure 14 and Figure 15As shown, the water deflector installation position can be selected to be distributed on the component frame 210 of the photovoltaic component 200, that is, the fixing portion 110 is used to be fixedly connected to the component frame 210. Specifically, the fixing portion 110 is used to be fixedly connected to the frame top surface, and / or frame side surface, and / or frame bottom surface of the component frame 210. Of course, the water deflector installation position can also be selected to be distributed on the component support device 300, that is, the fixing portion 110 is used to be fixedly connected to the component support device 300; the water deflector installation position can also be selected to be distributed on the bearing surface 400, that is, the fixing portion 110 is used to be fixedly connected to the bearing surface 400.

[0091] With this distribution method, the first gap a can be an open gap in the distribution direction of the fixed portion 110 and the water guide portion 120. Specifically, in the distribution direction of the fixed portion 110 and the water guide portion 120, one end of the first gap a is open, and the other end of the first gap a is also open; and the first gap a is continuous in the distribution direction of the fixed portion 110 and the water guide portion 120.

[0092] In another embodiment of the present application, Figure 17-22 、 Figure 27 and Figure 28 As shown, the fixing portion 110, the first transition portion 130 and the water guide portion 120 are distributed along the height direction of the water guide for photovoltaic modules. It can be understood that the height direction of the water guide for photovoltaic modules is Figure 18 、 Figure 20 、 Figure 22 and Figure 28 The fixing portion 110, the first transition portion 130 and the water guide portion 120 are distributed along the thickness direction of the component frame 210, such as Figure 18 、 Figure 20 、 Figure 22 and Figure 28 shown.

[0093] Using the above distribution method, such as Figure 17 、 Figure 19 、 Figure 21 and Figure 27 As shown, the projection of the water guide 120 adjacent to the fixed portion 110 on the projection plane can be selected to overlap with the projection of the fixed portion 110 within the projection plane. In this case, the fixed portion 110 can be located in the middle or at one end of the water guide 120 in the diversion width direction of the water guide 120. Of course, it is also possible to select a non-overlapping projection of the water guide 120 adjacent to the fixed portion 110 on the projection plane and the projection of the fixed portion 110 within the projection plane. It should be understood that the above projection plane is perpendicular to the height direction of the water guide for photovoltaic modules.

[0094] With the above distribution method, the number of the fixing portions 110 can be one or more. If there are more than two fixing portions 110, at least two fixing portions 110 can be connected to the same first transition portion 130. Alternatively, the fixing portions 110 and the water guide portions 120 can be arranged in a one-to-one correspondence. In this case, the first transition portions 130 can also be arranged in a one-to-one correspondence with the fixing portions 110.

[0095] Using the above distribution method, such as Figure 18 、 Figure 20 、 Figure 22 and Figure 28 As shown, the water deflector installation position can be selected to be distributed on the component frame 210 of the photovoltaic component 200, that is, the fixing portion 110 is used to be fixedly connected to the component frame 210. Specifically, the fixing portion 110 is used to be fixedly connected to the side surface of the component frame 210, and / or the fixing portion 110 is used to be fixedly connected to the bottom surface of the component frame 210.

[0096] Using the above distribution method, such as Figure 23 and Figure 24 As shown, the water deflector mounting positions may be distributed on the component support device 300, that is, the fixing portion 110 is used for fixed connection with the component support device 300. Specifically, the component support device 300 includes a pressing block 310, a purlin 320, and a clamp 330, wherein the purlin 320 is fixed to the clamp 330, the pressing block 310 is fixed to the purlin 320, and the water deflector mounting positions are distributed on the purlin 320, that is, the fixing portion 110 is used for fixed connection with the purlin 320.

[0097] Of course, the water guide installation positions may be distributed on the fixture 330 or the pressing block 310 according to actual needs. Accordingly, the component bracket device 300 may also have other structures and is not limited to the above embodiment.

[0098] Using the above distribution method, such as Figure 25 and Figure 26 As shown, the water guide installation positions can also be distributed on the bearing surface 400, that is, the fixing portion 110 is used for fixed connection with the bearing surface 400. Specifically, the bearing surface 400 is a roof surface.

[0099] The above distribution method avoids the formation of a dead angle between the water guide for the photovoltaic module and the module frame 210 after installation, thereby enhancing the anti-clogging performance of the water guide for the photovoltaic module.

[0100] In another embodiment of the present application, the two aforementioned embodiments may be combined. Specifically, there are at least two fixing portions 110, each of which is connected to a corresponding water guide portion 120 via a first transition portion 130. The at least one fixing portion 110, the first transition portion 130 corresponding to the fixing portion 110, and the water guide portion 120 are arranged along the diversion width of the water guide portion 120, and the at least one fixing portion 110, the first transition portion 130 corresponding to the fixing portion 110, and the water guide portion 120 are arranged along the height of the water guide for a photovoltaic module.

[0101] By adopting the above distribution method, at least one water-guiding part 120 can be selected to be connected to two fixed parts 110 through the first transition part 130, wherein one fixed part 110, its corresponding first transition part 130, and the water-guiding part 120 are distributed along the diversion width direction of the water-guiding part 120, and the other fixed part 110, its corresponding first transition part 130, and the water-guiding part 120 are distributed along the height direction of the water guide for photovoltaic modules.

[0102] Using the above distribution method, at least two water-guiding parts 120 can also be selected, at least one water-guiding part 120 is connected to the fixed part 110 through the first transition part 130 and the three are distributed along the diversion width direction of the water-guiding part 120, at least one water-guiding part 120 is connected to the fixed part 110 through the first transition part 130 and the three are distributed along the height direction of the water guide for photovoltaic modules.

[0103] Herein, the first transition portion 130 corresponding to the fixing portion 110 refers to the first transition portion 130 connected to the fixing portion 110 .

[0104] The specific structure of the first transition portion 130 is selected according to actual needs. In one embodiment of the present application, the first transition portion 130 includes: at least one flat plate and / or at least one curved plate.

[0105] If the first transition portion 130 only includes a flat plate, the flat plate and the fixed portion 110 can be arranged relative to each other at an angle so that the fixed portion 110, the first transition portion 130 and the water-guiding portion 120 form a through-groove structure; or the first transition portion 130 and the top surface of the fixed portion 110 can be arranged in parallel, in which case there is a gap between the top of the fixed portion 110 and the component frame 210.

[0106] If the first transition portion 130 comprises at least two flat plates, there is an angle between the at least two flat plates, which can be a right angle, an acute angle, or an obtuse angle. In order to facilitate production and manufacturing, the angle between the at least two flat plates can be a right angle. Figure 1-5 、 Figure 17-22 、 Figure 27 and Figure 28As shown, the first transition portion 130 includes three flat plates, with two adjacent flat plates arranged vertically. Figure 8 and Figure 9 As shown, the first transition portion 130 includes two flat plates, and two adjacent flat plates are vertically arranged.

[0107] like Figure 10 、 Figure 11 and Figure 13 As shown, the first transition portion 130 includes a curved plate. The type of the curved plate can be selected according to actual needs. For example, the curved plate can be an arc-shaped plate, etc. This embodiment does not limit this. In actual application, you can also choose Figure 10 、 Figure 11 and Figure 13 The curved plate shown is formed by splicing at least two curved plates.

[0108] In one embodiment of the present application, to enhance the diversion effect, the first transition portion 130 is a through-groove structure. It is understood that the notch of the through-groove structure is intended to face the frame 210 of the photovoltaic module 200; the notch of the through-groove structure is opposed to the bottom of the through-groove structure, and one of the two opposing sides of the through-groove structure is connected to the fixing portion 110, and the other side is connected to the water diversion portion 120. In this embodiment, the first transition portion 130 includes at least two flat plates and / or at least one curved plate, i.e., at least two flat plates and / or at least one curved plate form the through-groove structure.

[0109] In the above-mentioned water guide for photovoltaic modules, the first transition portion 130 connects the fixed portion 110 and the adjacent water guide portion 120 , that is, one end of the first transition portion 130 is connected to the fixed portion 110 , and the other end of the first transition portion 130 is connected to the adjacent water guide portion 120 .

[0110] In practical applications, such as Figure 1-6 、 Figure 8-11 、 Figure 13 、 Figures 27-29 As shown, the first transition portion 130 is connected to the water guide portion 120 adjacent to the fixing portion 110; or Figure 17-22 As shown, the water guide portion 120 and the first transition portion 130 adjacent to the fixing portion 110 have an overlapping portion.

[0111] To enhance connection strength, the water guide portion 120 adjacent to the fixed portion 110 and the first transition portion 130 may overlap. To minimize interference with flow diversion, the first transition portion 130 may be connected to the top surface of the water guide portion 120 adjacent to the fixed portion 110. It should be understood that the top surface of the water guide portion 120 is the side of the water guide portion 120 that faces away from the diversion channel b. This means that the top surface of the water guide portion 120 faces away from the diversion channel b.

[0112] In one embodiment of the present application, if at least one fixed portion 110, its corresponding first transition portion 130, and the water guide portion 120 are selected to be distributed along the diversion width direction of the water guide portion 120, the top of at least one fixed portion 110 can be selected to be higher than the top of the water guide portion 120; or, the top of at least one fixed portion 110 can be selected to be lower than the top of the water guide portion 120 and the fixed portion 110 can be lower than the first transition portion 130 corresponding to it; or, the top of at least one fixed portion 110 can be flush with the top of the water guide portion 120.

[0113] In the above embodiment, if the top of the fixed portion 110 is higher than the top of the water-guiding portion 120 or the tops of the fixed portion 110 and the tops of the water-guiding portion 120 are flush, the first transition portion 130 may be located at the top of the fixed portion 110, or in the middle or bottom of the fixed portion 110. If the top of the fixed portion 110 is lower than the top of the water-guiding portion 120 and the first transition portion 130 is higher than the fixed portion 110, the first transition portion 130 is located at the top of the fixed portion 110. To facilitate installation and improve the diversion effect, the first transition portion 130 may be selected to connect the top of the fixed portion 110 and the top of the water-guiding portion 120, and the first transition portion 130 may be higher than the fixed portion 110. In this case, the first transition portion 130 is located at the top of the fixed portion 110 and the top of the water-guiding portion 120.

[0114] In one embodiment of the above structure, Figure 8 and Figure 9 As shown, the top of the water guide portion 120 can be flush with the top of the first transition portion 130; or Figure 1-5 、 Figure 7 、 Figure 10-15 The top of the water guide portion 120 is lower than the top of the first transition portion 130 .

[0115] In one embodiment of the present application, in order to improve the strength, especially the strength of the fixing portion 110, as shown in FIG. Figure 2 As shown, at least one fixing portion 110 is provided with a flange 112. It is understood that, in this case, there can be one fixing portion 110 or more than two fixing portions 110. The position of the flange 112 can be selected according to actual needs, as long as it does not affect the flow diversion.

[0116] In one embodiment of the above structure, the flange 112 is used to form a first flow-guiding gap with the component frame 210. This not only increases the structural strength of the fixing portion 110, but also enables the flange 112 to achieve a water-guiding function, thereby improving the water-guiding effect.

[0117] If the fixed portion 110, first transition portion 130, and water guide portion 120 are distributed along the diversion width of the water guide portion 120, the cross-sectional area of the water guide channel can be increased, allowing water accumulated in the component to be discharged in a shorter time. Given the same dust settling rate in the water, the water diversion and dust removal effects are improved. In this case, the flange 112 is located at the top of the fixed portion 110 connected to the first transition portion 130, or the flange 112 is located at the top of the fixed portion 110 connected to the first transition portion 130, and on both sides of the middle portion of the fixed portion 110 connected to the top.

[0118] In practical applications, other methods can also be used to improve the diversion effect. Figure 3 As shown, at least one guide groove 113 is provided on the inner side of at least one fixed portion 110. The guide groove 113 is used to form a second guide gap with the component frame 210, thereby improving the drainage efficiency. In this case, there can be one fixed portion 110 or more than two. If the fixed portion 110, the first transition portion 130 and the water guide portion 120 are distributed along the guide width direction of the water guide portion 120, the guide groove 113 extends from the top of the fixed portion 110 to the bottom of the fixed portion 110, thereby increasing the cross-sectional area of the water guide channel, and the accumulated water in the photovoltaic component 200 can be discharged in a shorter time. When the dust sedimentation speed in the water is the same, the water guide effect and dust removal effect are better.

[0119] It is understandable that the inner side of the fixing portion 110 refers to a side of the fixing portion 110 that is close to the component frame 210 .

[0120] In one embodiment of the above structure, the guide groove 113 is formed by the fixing portion 110 protruding to one side, which can also improve the structural strength of the fixing portion 110. Of course, if the strength of the fixing portion 110 meets the requirements, the guide groove 113 can also be directly formed on the surface of the fixing portion 110, and is not limited to the above embodiment.

[0121] The number of the guide grooves 113 can be one or more than two, which can be selected according to actual needs and is not limited in this embodiment.

[0122] In the above photovoltaic module water guide, the shape of the fixing portion 110 is selected according to actual needs. Figure 13 、 Figure 17 、 Figure 18 、 Figure 21 、 Figure 22 、 Figure 24 、 Figure 25 、 Figure 27 and Figure 28 As shown, the fixing portion 110 is in the shape of a letter "I"; Figure 11 and Figure 12 、 Figure 19 and Figure 20As shown, the fixing part 110 is L-shaped; as Figure 1-5 , Figure 7-10 and Figure 29 shown, the above-mentioned fixing part 110 is in a "U" shape. Of course, the above-mentioned fixing part 110 can also be selected in other shapes, not limited to the above limitations.

[0123] In a specific embodiment, at least one fixing part 110 has a fixing structure for directly fixing to the water guide device installation position. Specifically, the above-mentioned fixing structure is a fixing surface for bonding or magnetically attracting to the water guide device installation position; or, the fixing structure is a fixing hole for installing to the water guide device installation position through a fastener; or, the fixing structure is a slot structure for clamping to the water guide device installation position. Of course, the above-mentioned fixing structure can also be selected in other ways, not limited to the above embodiments.

[0124] In the actual application process, in order to improve stability, the above-mentioned fixing part 110 is a fixing surface for bonding to the water guide device installation position. At this time, the fixing part 110 is used for bonding to the water guide device installation position. This method is particularly suitable for the case where the above-mentioned fixing part 110 is L-shaped or "one" shaped. Specifically, if the above-mentioned fixing part 110 is L-shaped, the L-shaped fixing part 110 and the component frame 210 can be positioned for easy bonding and fixing; if the above-mentioned fixing part 110 is "one" shaped, the structure is relatively simple and the installation is also relatively simple. Of course, the above-mentioned fixing part 110 can also be selected in a "U" shape or other shapes.

[0125] In a specific embodiment, for the convenience of disassembly and assembly, the above-mentioned fixing structure is a slot structure for clamping to the water guide device installation position. This method is particularly suitable for the case where at least one fixing part 110, and its corresponding first transition part 130 and water guide part 120 are distributed along the diversion width direction of the water guide part 120, and is also particularly suitable for the case where the above-mentioned fixing part 110 is in a "U" shape. Of course, the above-mentioned fixing part 110 can also be selected in other shapes.

[0126] In another embodiment of the above structure, as Figure 4 shown, at least one fixing part 110 includes a first fixing plate, a second fixing plate and a third fixing plate that are fixedly connected in sequence. The first fixing plate and the third fixing plate are respectively located at both ends of the second fixing plate and form a slot structure; among them, at least one of the first fixing plate, the second fixing plate and the third fixing plate is provided with a threaded hole 114 and a screw or bolt passing through the threaded hole 114.

[0127] It can be understood that the screw or bolt is in threaded cooperation with the threaded hole 114, and the whole fixing part 110 is clamped to the component frame 210 by the screw or bolt abutted against the component frame 210. At this time, the water guide device installation positions are distributed on the component frame 210. Of course, the water guide device installation positions can also be selected to be distributed at other positions, and this embodiment does not limit this.

[0128] The number of threaded holes 114 is selected according to actual needs and is not limited in this embodiment. Figure 3 As shown, if the fixing portion 110 is provided with a guide groove 113 , the threaded hole 114 may be optionally provided in the guide groove 113 .

[0129] In another embodiment, Figure 15 and Figure 16 As shown, the water deflector for photovoltaic modules further includes a fixing auxiliary component 150 , which is used to be fixed at the water deflector installation position, and at least one fixing portion 110 is indirectly fixed at the water deflector installation position through the fixing auxiliary component 150 .

[0130] The type of the fixing auxiliary member 150 can be selected according to actual needs. Figure 15 and Figure 16 As shown, the fixing auxiliary member 150 is a clamping member used to clamp and fix the corresponding fixing portion 110 to the water deflector mounting position. In this case, the water deflector mounting position is distributed on the component frame 210. Of course, the water deflector mounting position can also be distributed in other positions, and this embodiment is not limited to this.

[0131] In practical applications, the auxiliary fixing member may also be configured as another structure, not limited to a clamping member. For example, the auxiliary fixing member may be a connecting plate, one end of which is fixedly connected to the fixing portion 110, and the other end of which is fixed to the water guide installation position. This embodiment is not limited to this.

[0132] In actual application, the temperature of the water guide for photovoltaic modules changes, and the water guide for photovoltaic modules is easy to deform. In order to avoid the water guide for photovoltaic modules from falling off due to deformation, Figure 1-3 、 Figure 10 As shown, at least one of the fixing portions 110 is provided with a barb structure 111 capable of piercing the water guide installation position.

[0133] The specific position and number of the barb structures 111 are selected based on actual conditions and are not limited in this embodiment.

[0134] In the above structure, the barb structure 111 can enhance the connection stability between the fixing portion 110 and the water deflector mounting position, especially when the fixing portion 110 is snap-fitted to the water deflector mounting position. Of course, the barb structure 111 can also be provided when the fixing portion 110 is bonded to the water deflector mounting position.

[0135] On the other hand, in order to further avoid clogging of the diversion channel b, the present application Figure 10 、 Figure 11 and Figure 13As shown, the water guide 120 is provided with at least one through-hole 124. It will be appreciated that through-hole 124 is connected to the diversion channel b. This allows external water (rainwater or water sprayed by a spraying device) to enter the diversion channel b through through-hole 124, thereby disturbing and flushing dust within the water guide 120. This facilitates the discharge of dust from the diversion channel b along with the water flow, thus enhancing the anti-clogging capability.

[0136] The number, size and specific location of the through holes 124 are selected according to actual needs. In order to improve the cleaning effect, at least two through holes 124 can be selected and distributed in sequence along the diversion direction of the diversion channel b.

[0137] In practical applications, the through holes 124 may be formed by drilling holes in the water guide 120 , or a component with through holes 124 may be provided on the water guide 120 , for example, a mesh component with through holes 124 may be provided on the water guide 120 .

[0138] In one embodiment of the present application, in order to facilitate flow diversion, as Figure 7 As shown, the water guide 120 comprises a water diversion section 121, a water diversion section 122, and a drainage section 123, which are connected in sequence. The water diversion section 121 is used to attract water accumulated on the photovoltaic module 200, while the water diversion section 122 is used to guide the accumulated water attracted by the water diversion section 121 to the drainage section 123, which is used to drain the accumulated water. The water diversion section 121 and the water diversion section 122 form a first angle, while the water diversion section 122 and the drainage section 123 form a second angle. In this structure, the water diversion section 121 and the water diversion section 122 are essential components of the water diversion section 120; the provision of the drainage section 123 improves the diversion and drainage performance.

[0139] Specifically, after the above-mentioned fixing part 110 is installed in the water guide installation position, a diversion channel b is formed between the water guide part 120 and the photovoltaic component 200. The diversion channel b includes: a first diversion section b1 formed by the water guide section 121 and the packaging glass and the component frame 210, a second diversion section b2 formed by the water guide section 122 and the component frame 210, and a third diversion section b3 formed by the drainage section 123 and the component frame 210. The first diversion section b1, the second diversion section b2, and the third diversion section b3 are connected in sequence to form a continuous and unobstructed diversion channel b to divert and discharge the accumulated water on the photovoltaic component 200.

[0140] The specific shape of the water guide portion 120 can be selected based on actual needs. Optionally, the water diversion section 121, water diversion section 122, and drainage section 123 are all flat plate structures, with the water diversion section 121 and the water diversion section 122 transitionally connected by a first transition section, and the water diversion section 122 and the drainage section 123 transitionally connected by a second transition section. It is understood that both the first and second transition sections can be curved, such as arc-shaped, but this embodiment is not limited thereto.

[0141] In actual application, the drainage section 123 and the water guide section 122 may be arranged in parallel, and are not limited to the above embodiment. At least one of the water guide section 121, the water guide section 122 and the drainage section 123 may be a curved plate, and are not limited to a flat plate structure.

[0142] In another embodiment of the present application, in order to simplify the structure, the water guide portion 120 may only include: a water diversion section 121 and a water guide section 122 connected in sequence, that is, the water guide portion 120 does not include a drainage section 123 .

[0143] In the water guide for the photovoltaic module, Figure 5 、 Figure 9 、 Figure 17-22 、 Figure 27 and Figure 28 As shown, there is one water guide portion 120, which is located on one side of the fixing portion 110; Figure 1-4 、 Figure 6 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 12 As shown, there are two water guides 120 , one water guide 120 is located on one side of the fixing portion 110 , and the other water guide 120 is located on the other side of the fixing portion 110 .

[0144] In the above-mentioned water guide for photovoltaic modules, if there are two water guide portions 120 , the two water guide portions 120 may be located on the same side of the fixing portion 110 .

[0145] On the other hand, in order to improve the water conduction efficiency, the present application Figure 29 As shown, there are at least two adjacent water guides 120, and the two adjacent water guides 120 are connected by a second transition portion 140 so that there is a second gap c between the two adjacent water guides 120. It can be understood that the two water guides 120 are adjacent, which means that there is no fixed portion 110 and the first transition portion 130 between the water guides 120. The second transition portion 140 is used to have a preset distance with the photovoltaic component 200, and the preset distance is greater than zero to avoid the second transition portion 140 blocking the second gap c. Specifically, the above-mentioned second gap c is an open gap in the diversion direction of the diversion channel b, and the above-mentioned second gap c is an open gap in the distribution direction of any two water guides 120. In this way, the cross-sectional area of the diversion channel b can be increased, and the accumulated water in the component can be discharged in a shorter time. Under the condition that the dust sedimentation speed in the water is the same, the water diversion effect and dust removal effect are better.

[0146] The second transition portion 140 is flush with the top of the water guide portion 120, or the second transition portion 140 is higher than the water guide portion 120. In order to improve the water guide effect, the second transition portion 140 can be selected to be higher than the water guide portion 120.

[0147] The specific structure of the second transition portion 140 is selected according to actual needs. Optionally, the second transition portion 140 is a through-slot structure. It is understood that the notch of the through-slot structure is used to face the component frame 210.

[0148] In another aspect of the present application, to simplify the structure, the fixing portion 110, the water guide portion 120, and the first transition portion 130 may be an integrated structure. Furthermore, the fixing portion 110, the water guide portion 120, and the first transition portion 130 may be an integrated structure. Of course, at least two of the fixing portion 110, the water guide portion 120, and the first transition portion 130 may also be separate structures, and the present invention is not limited to the above embodiment.

[0149] It is understandable that if the water guide for a photovoltaic assembly includes the second transition portion 140 , the fixing portion 110 , the water guide portion 120 , the first transition portion 130 and the second transition portion 140 may be an integrated structure.

[0150] The various situations mentioned in the above embodiments can be combined accordingly according to actual needs. In order to more specifically illustrate the technical solution provided by this embodiment, five embodiments are described below.

[0151] Implementation

[0152] like Figure 1-7 As shown, the water deflector for a photovoltaic module provided in this first embodiment includes: a fixed portion 110, a water deflector 120, and a first transition portion 130. In this first embodiment, the fixed portion 110, the first transition portion 130, and the water deflector 120 are arranged along the diversion width of the water deflector 120; the top of the first transition portion 130 is higher than the top of the water deflector 120, and the first transition portion 130 is higher than the fixed portion 110.

[0153] The functions and effects of the fixing portion 110 , the water guide portion 120 and the first transition portion 130 can be found in the foregoing description and will not be repeated here.

[0154] like Figure 1-5 、 Figure 7 As shown, the above-mentioned fixing portion 110 includes a first fixing plate, a second fixing plate and a third fixing plate fixedly connected in sequence; wherein, the first fixing plate, the second fixing plate and the third fixing plate are all flat plates, the first fixing plate and the third fixing plate are arranged in parallel, and the first fixing plate and the third fixing plate are both perpendicular to the second fixing plate; the first fixing plate and the third fixing plate are respectively located at both ends of the second fixing plate, and the first fixing plate and the third fixing plate are both located on the same side of the second fixing plate.

[0155] The fixing method of the fixing portion 110 can be selected according to the needs.

To improve stability, the first fixing plate and / or the third fixing plate are provided with a barb structure 111. Of course, the second fixing plate may also be provided with a barb structure 111, which is not limited in this embodiment.

[0156] In order to facilitate the connection, you can use Figure 3 The structure shown.

The screw is threadedly engaged with the threaded hole 114, and the entire fixing portion 110 is fixed to the component frame 210 by the screw abutting against the component frame 210 and the slot structure. In addition, the fixing portion 110 is provided with a guide groove 113, which is distributed on the first fixing plate, the second fixing plate and the third fixing plate. In this case, the threaded hole 114 is provided in the guide groove 113. The guide groove 113 is formed by the fixing portion 110 protruding to one side, which not only improves the diversion effect and efficiency, but also improves the structural strength of the entire fixing portion 110.

[0157] In order to facilitate the card connection, it is also used Figure 4 The structure shown. Figure 4 As shown, in the fixing part 110, the first fixing plate, the second fixing plate and the third fixing plate are all provided with threaded holes 114 and screws passing through the threaded holes 114. The screws are threadedly engaged with the threaded holes 114, and all the screws are abutted against the component frame 210 to achieve the fixing of the entire fixing part 110 to the component frame 210.

[0158] To optimize the flow diversion, the first and second fixing plates of the fixing portion 110 may be provided with flanges 112, which not only improves the flow diversion efficiency and effect, but also increases the structural strength of the fixing portion 110. Of course, only the first fixing plate may be provided with flanges 112, which is not limited in this embodiment.

[0159] In the above-mentioned fixing portion 110, the angle between the second fixing plate and the first fixing plate can be an acute angle, and the angle between the third fixing plate and the second fixing plate can be an acute angle; at least one of the first fixing plate, the second fixing plate and the third fixing plate can also be a curved plate, for example, the above-mentioned fixing portion 110 is C-shaped, but is not limited to the above limitation.

[0160] In the first embodiment, the top of the fixing portion 110 is used to contact the module frame 210 , and the top of the water guide portion 120 is higher than the top of the fixing portion 110 to ensure that the water guide portion 120 and the photovoltaic module 200 form a diversion channel b.

[0162] In the first embodiment, for the specific structure of the water guide portion 120 , please refer to the above description and will not be repeated here.

[0163] In this first embodiment, the first transition portion 130 is a through-groove structure. Specifically, the first transition portion 130 includes two parallel vertical plates and a horizontal plate. The two vertical plates are perpendicular to the horizontal plate. One vertical plate is connected to the fixing portion 110, and the other vertical plate is connected to the water guide portion 120. The two vertical plates are of unequal lengths. The angle between the vertical and horizontal plates in the first transition portion 130 can be acute or obtuse, and this is not limited in this first embodiment.

Specifically, the fixing part 110 is in an L shape. At this time, it can be selected that the fixing surface is located on the side surface of the fixing part 110, that is, the side surface of the fixing part 110 is used for bonding with the side surface of the component frame 210.
