Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a horizontal photovoltaic component installation structure. [Background technology]

[0002] Photovoltaic modules are rectangular structures. Existing photovoltaic power stations usually use rectangular photovoltaic module arrays, which have three installation methods: horizontal installation, vertical installation, and horizontal and vertical combination. The horizontal installation method means that the length direction of the photovoltaic module is consistent with the horizontal direction, the vertical installation method means that the length direction of the photovoltaic module is consistent with the vertical direction, and the horizontal and vertical combination installation method means the combination of horizontal photovoltaic modules and vertical photovoltaic modules.

[0003] Currently, vertically mounted photovoltaic modules are all fixed on the long side, and short side fixation is not allowed. However, in scenarios where photovoltaic modules are all installed horizontally and need to be equipped with longitudinal water guide grooves, the short side fixing method has to be used for installation, because the longitudinal water guide groove needs to be fixed, and the longitudinal water guide groove can only be installed along the inclination angle of the photovoltaic module.

[0004] However, the short side fixed in the long side span of the module may have a large deflection and deformation under the action of gravity, and may also deform upward in the long side span under the action of wind suction load. Over time, it will affect the quality of the photovoltaic module and the power generation, and there will be a risk of falling or breaking. [Contents of the utility model]

[0005] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a horizontally mounted photovoltaic assembly installation structure to solve the problem that deformation is easily generated in the middle of the long side span of the horizontally mounted photovoltaic assembly.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A horizontally mounted photovoltaic assembly installation structure includes a plurality of horizontal beams arranged side by side in the longitudinal direction, and the horizontally mounted photovoltaic assembly is fixed on the horizontal beams. The horizontally mounted photovoltaic assembly installation structure also includes an intermediate support member arranged below the middle position of the length of the photovoltaic assembly and extending along the width direction of the photovoltaic assembly. The upper side of the intermediate support member is connected to the frame on both sides of the width of the photovoltaic assembly, and the lower side is connected to the horizontal beams to limit the upper and lower deformation of the middle position of the length of the photovoltaic assembly.

[0008] Preferably, the upper part of the intermediate support member is provided with an upper support portion extending obliquely upward to both lateral sides, the upper end of the upper support portion is provided with an upper fixing portion extending horizontally to the outer side in the lateral direction, and the upper fixing portion is fixed to the frame of the photovoltaic module by means of support fasteners; the lower part of the intermediate support member is provided with a lower support portion extending obliquely downward to both lateral sides, the lower end of the lower support portion is provided with a lower fixing portion extending horizontally to the outer side in the lateral direction, and the lower fixing portion is fixed to the crossbeam by means of support fasteners.

[0009] Preferably, the support member fastener is a self-drilling screw; and / or, the middle portion of the intermediate support member is provided with an intermediate connecting portion extending laterally and connecting the upper supporting portion and the lower supporting portion.

[0010] Preferably, the intermediate support member is composed of two upper and lower isosceles trapezoidal sheet metal members, and the upper bottoms of the upper and lower sheet metal members are welded together.

[0011] Preferably, the intermediate support member extends integrally along the entire longitudinal direction of the horizontally mounted photovoltaic assembly.

[0012] Preferably, a longitudinal water guide groove is provided below the length end of the photovoltaic component, and the longitudinal water guide groove is connected to a pressing block assembly for fixing the photovoltaic component, and the pressing block assembly includes a lower pressing block supporting the photovoltaic component, an upper pressing block pressed on the upper side of the photovoltaic component, and a pressing block fastener connecting the upper pressing block and the lower pressing block.

[0013] Preferably, the longitudinal water guide groove is an M-shaped structure, and side fixing edges extending laterally outward are provided on both sides of the bottom of the longitudinal water guide groove, and the side fixing edges are fixed to the cross beam by screws; and / or, a transverse water guide groove is provided below the gap between two longitudinally adjacent photovoltaic components in the horizontally mounted photovoltaic component, and the transverse water guide groove is connected to the longitudinal water guide groove.

[0014] Preferably, the upper pressing block is provided with a U-shaped portion and side wings extending outward from both sides of the mouth of the U-shaped portion, the U-shaped portion is inserted into the gap between two adjacent photovoltaic modules, and the side wings are pressed onto the side A of the frame of the photovoltaic module.

[0015] Preferably, the lower pressing block is provided with a supporting surface supported on the bottom surface of the C side of the photovoltaic module frame, and the lateral sides of the lower pressing block are provided with folding parts folded toward the sides of the longitudinal water guide groove, and the folding parts are fixed to the sides of the longitudinal water guide groove by screws.

[0016] Preferably, the lower pressing block is provided with upper convex parts on both lateral sides thereof to cooperate with the lateral sides of the longitudinal water guide groove, and the lower pressing block is provided with a concave part between the supporting surface and the upper convex parts; and / or, the bottom surface of the side wing is provided with a serrated surface.

[0017] The utility model adopts the above technical solution and has the following beneficial effects:

[0018] 1. An intermediate support is set below the middle position of the length of the horizontally mounted photovoltaic module. The intermediate support extends along the width direction of the photovoltaic module, and the upper side of the intermediate support is connected to the frames on both sides of the width of the photovoltaic module, and the lower side is connected to the crossbeam to limit the vertical deformation of the middle position of the length of the photovoltaic module. In this way, since the intermediate support can limit the vertical deformation of the middle position of the length of the photovoltaic module, the photovoltaic module will not produce a large deformation in the middle of the span under the action of gravity load or wind suction load, ensuring the safety of the photovoltaic module and the power generation quality.

[0019] 2. The two upper supporting parts on the upper side of the intermediate supporting member and the two lower supporting parts on the lower side are combined to form an X-shaped structure. The advantages are, first, saving materials and thus cost. Secondly, it can play a good supporting role, because the two upper supporting parts can support the photovoltaic modules under the support of the two lower supporting parts, thereby preventing the middle part of the photovoltaic modules from deforming downward under the action of gravity load. If the photovoltaic modules are subjected to wind suction loads, since the lower side of the lower supporting parts is fixed, the two lower supporting parts pull the two upper supporting parts downward, and the two upper supporting parts pull the photovoltaic modules, thereby preventing the middle part of the photovoltaic modules from deforming upward.

[0020] 3. The middle support is fixed to the frame and beam of the photovoltaic module by self-drilling screws. Therefore, it can be rotated and drilled into the frame and beam of the photovoltaic module by using the taper to achieve the effect of self-drilling and self-tapping, which greatly facilitates the installation, and the installation is reliable and not easy to loosen.

[0021] The middle connecting part can bear the downward pressure of the upper supporting part, and can also bear the upward pressure of the lower supporting part, thereby improving the bearing capacity of the middle supporting member.

[0022] 4. The middle support is composed of two isosceles trapezoidal sheet metal parts, and the upper and lower bottoms of the two sheet metal parts are welded together. Since the sheet metal parts have the advantages of light weight, high strength, low cost, and good large-scale mass production performance, the two sheet metal parts are welded and fixed as one, which is convenient for processing. Therefore, the industrial production of the middle support can be realized, which significantly reduces the cost.

[0023] 5. Since the intermediate support extends integrally along the entire longitudinal direction of the horizontally mounted photovoltaic modules, a row of photovoltaic modules only requires one intermediate support for easy installation. At the same time, since the intermediate support provides support in the entire longitudinal direction, the support is comprehensive and the supporting effect is good.

[0024] 6. Use a pressure block assembly to fix the photovoltaic module to the longitudinal water guide groove to achieve fixation of both ends of the length of the photovoltaic module.

[0025] 7. Since a transverse water guide groove is provided below the gap between two longitudinally adjacent photovoltaic modules in a horizontally mounted photovoltaic module, and the transverse water guide groove is connected to the longitudinal water guide groove, the water on the surface of the photovoltaic module flows to the transverse water guide groove and then converges into the longitudinal water guide groove to achieve smooth drainage.

[0026] 8. The side wings on both sides of the U-shaped opening of the upper pressing block are pressed onto the A side of the photovoltaic module frame, thereby pressing and fixing the photovoltaic module.

[0027] 9. The lower pressing block is supported on the bottom surface of the C side of the photovoltaic module frame through the supporting surface, and then the photovoltaic module is clamped and fixed with the pressing of the upper pressing block;

[0028] The folded parts on both sides of the lower pressing block are fixed to the sides of the longitudinal water guide groove by screws, so that the longitudinal water guide groove has both drainage and load-bearing functions for the photovoltaic components.

[0029] 10. The shape of the lower pressing block matches the M-shaped structure of the longitudinal water guide groove, which can not only effectively support the photovoltaic modules, but also ensure the reliable fixation of the lower pressing block and the longitudinal water guide groove;

[0030] Since the bottom surface of the side wing is provided with a serrated surface, the friction between the side wing and the side A of the photovoltaic module frame can be increased to avoid loosening.

[0031] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[Specific implementation method]

[0038] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0039] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0040] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0043] Reference Figures 1 to 4As shown, a horizontal photovoltaic assembly installation structure, a plurality of horizontal photovoltaic assemblies 100 are arranged in a rectangular array, and the horizontal photovoltaic assembly installation structure includes a plurality of crossbeams 200 arranged side by side in the longitudinal direction, and the width sides (long sides) of the horizontal photovoltaic assembly 100 are fixed on the crossbeams 200. The horizontal photovoltaic assembly installation structure also includes an intermediate support member 300 arranged below the middle position of the length of the photovoltaic assembly and extending along the width direction of the photovoltaic assembly, and the upper side of the intermediate support member 300 is connected to the width side frames 101 of the photovoltaic assembly, and the lower side is connected to the crossbeam 200, so as to limit the upper and lower deformation of the middle position of the length of the photovoltaic assembly.

[0044] In the above technical solution, since the intermediate support can limit the upward and downward deformation of the middle position of the length of the photovoltaic module, the photovoltaic module will not produce large deformation in the mid-span under the action of gravity load or wind suction load, thereby ensuring the safety and power generation quality of the photovoltaic module.

[0045] Specifically, Figure 3 As shown, the upper portion of the intermediate support member 300 is provided with an upper support portion 32 extending obliquely upward to both sides in the lateral direction, and the upper end of the upper support portion is provided with an upper fixing portion 31 extending horizontally outward in the lateral direction, and the upper fixing portion 31 is fixed to the photovoltaic module frame 101 by a support fastener. The lower portion of the intermediate support member 300 is provided with a lower support portion 34 extending obliquely downward to both sides in the lateral direction, and the lower end of the lower support portion 34 is provided with a lower fixing portion 35 extending horizontally outward in the lateral direction, and the lower fixing portion 35 is fixed to the crossbeam 200 by a support fastener.

[0046] In the above technical solution, the two upper support parts on the upper side of the intermediate support member and the two lower support parts on the lower side are combined to form an X-shaped structure. The advantages are, first, saving materials and thus saving costs. Secondly, it can play a good supporting role, because the two upper support parts can support the photovoltaic module under the support of the two lower support parts, thereby preventing the middle part of the photovoltaic module from deforming downward under the action of gravity load. If the photovoltaic module is subjected to wind suction load, since the lower side of the lower support part is fixed, the two lower support parts pull the two upper support parts downward, and the two upper support parts pull the photovoltaic module, thereby preventing the middle part of the photovoltaic module from deforming upward.

[0047] Wherein, the support fastener is a self-drilling screw. Therefore, it can be rotated and drilled into the frame and beam of the photovoltaic module by itself using the taper, achieving the effect of self-drilling and self-tapping, which greatly facilitates the installation, and further glues to prevent loosening, so the installation is reliable and not easy to loosen. The middle part of the intermediate support member 300 is provided with an intermediate connecting part 33 that extends laterally and connects the upper support part and the lower support part. The intermediate connecting part can bear the downward pressure of the upper support part, and can also bear the upward pressure of the lower support part, thereby improving the bearing capacity of the intermediate support member.

[0048] Furthermore, the intermediate support member 300 is composed of two upper and lower isosceles trapezoidal sheet metal parts, and the upper and lower bottoms of the two sheet metal parts are welded together. Since sheet metal parts have the advantages of light weight, high strength, low cost, and good mass production performance, the two sheet metal parts are welded and fixed as one, which is convenient for processing, thereby realizing the industrialized production of the intermediate support member and significantly reducing the cost.

[0049] In this embodiment, the intermediate support member 300 extends integrally along the entire longitudinal direction of the horizontally mounted photovoltaic assembly. Therefore, a row of photovoltaic assemblies only requires one intermediate support member for easy installation. At the same time, since the intermediate support member supports the entire longitudinal direction, the support is comprehensive and the support effect is good. Of course, it is understandable that the intermediate support member can also be divided into multiple sections along the entire longitudinal direction of the horizontally mounted photovoltaic assembly and spliced ​​into a whole.

[0050] Referring to the prior art, a longitudinal water guide groove 400 is provided between the length end of the photovoltaic module and the crossbeam, and the longitudinal water guide groove 400 can extend integrally along the entire longitudinal direction of the horizontally mounted photovoltaic module. Moreover, a transverse water guide groove 600 is provided below the gap between two longitudinally adjacent photovoltaic modules in the horizontally mounted photovoltaic module, and the transverse water guide groove 600 is connected to the longitudinal water guide groove 400, so that the water on the surface of the photovoltaic module flows to the transverse water guide groove and then converges to the longitudinal water guide groove. Of course, it can be understood that the gap can also be not provided, and the water on the surface of the photovoltaic module flows into the longitudinal water guide groove. In addition, a main water trough is usually provided below the longitudinal direction of the horizontally mounted photovoltaic module, and the lower end of the longitudinal water guide groove is connected to the main water trough. In this way, the water flow first converges from the transverse water guide groove to the longitudinal water guide groove, and then from the longitudinal water guide groove to the main water trough, and finally the main water trough is connected to the drain pipe, forming a well-defined drainage path, which is conducive to speeding up drainage and avoiding leakage.

[0051] Referring to the prior art, in order to fix the photovoltaic assembly, the longitudinal water guide groove 400 is connected with a pressing block assembly 500 for fixing the photovoltaic assembly, and the pressing block assembly 500 includes a lower pressing block 51 for supporting the photovoltaic assembly, an upper pressing block 52 pressed on the upper side of the photovoltaic assembly, and a pressing block fastener 53 connecting the upper pressing block 52 and the lower pressing block 51. Thus, the fixing of the two ends of the length of the photovoltaic assembly is achieved.

[0052] In this embodiment, the longitudinal water guide groove 400 is an M-shaped structure, and the bottom sides of the longitudinal water guide groove are provided with side fixing edges 41 extending laterally outward, and the side fixing edges 41 are fixed to the cross beam by screws, for example, self-drilling screws and glue. A bottom support 42 is provided in the middle of the bottom of the longitudinal water guide groove 400, which is supported on the cross beam.

[0053] Specifically, the upper pressing block 52 is provided with a U-shaped portion 521 and side wings 522 extending outward from both sides of the mouth of the U-shaped portion. The U-shaped portion 521 is inserted into the gap between two adjacent photovoltaic modules, and the side wings 522 are pressed against the A side of the photovoltaic module frame. The photovoltaic module is thereby pressed and fixed. The lower pressing block 51 is provided with a supporting surface 514 supported on the bottom surface of the C side of the photovoltaic module frame, and the lateral sides of the lower pressing block are provided with folding portions 511 folded toward the side of the longitudinal water guide groove, and the folding portions 511 are fixed to the side of the longitudinal water guide groove by screws, for example, also fixed by self-drilling screws and glue. In addition, the lateral sides of the lower pressing block are provided with upper convex portions 512 that cooperate with the lateral sides of the longitudinal water guide groove, and the lower pressing block 51 is provided with a lower concave portion 513 between the supporting surface and the convex portion. The bottom surface of the side wing is provided with a serrated surface.

[0054] In the above technical solution, the lower pressing block is supported on the bottom surface of the C side of the frame of the photovoltaic module through the supporting surface, and then the photovoltaic module is clamped and fixed by the pressing of the upper pressing block. The folding parts on both sides of the horizontal direction of the lower pressing block are fixed to the side of the longitudinal water guide groove by screws, so that the longitudinal water guide groove has both drainage and load-bearing functions for the photovoltaic module, and after being fixed as a whole with the crossbeam and the photovoltaic module, it is not easy to bend and twist, which can solve the problems of leakage caused by bending and twisting of the water tank in the prior art, improve the waterproof performance of the photovoltaic power station, and reduce the frequency and maintenance cost. The shape of the lower pressing block is matched with the M-shaped structure of the longitudinal water guide groove, which can not only effectively support the photovoltaic module, but also ensure the reliable fixation of the lower pressing block and the longitudinal water guide groove. In addition, the width sides (long sides) of the horizontal photovoltaic module 100 are fixed on the crossbeam 200 through the longitudinal water guide groove, and the middle position of the length of the photovoltaic module is fixed on the crossbeam 200 through the intermediate support member 300.

[0055] In addition, since the bottom surface of the side wing is provided with a serrated surface, the friction between the side wing and the side A of the photovoltaic module frame can be increased to prevent loosening.

[0056] The installation process of the horizontal photovoltaic module in this embodiment is as follows: after the photovoltaic bracket is constructed, first fix the longitudinal water guide 400 according to the position of the short side of the horizontal photovoltaic module, then place the middle support member 300 below the middle position of the module length, and use self-drilling screws to fix the middle support member 300 to the crossbeam 200. Then install the transverse water guide 600, and finally install the module, and use self-drilling screws to fix the connection position of the frame 101 on both sides (long sides) of the module width and the middle support member 300.

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
