Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic installation, and in particular relates to a photovoltaic component fixing structure capable of resisting deformation of a U-steel end. [Background technology]

[0002] Conventional photovoltaic power station brackets are provided with purlins, and photovoltaic modules are installed on the purlins. Usually, the ends of the purlins exceed the edges of the photovoltaic modules, and edge pressure block assemblies are provided near the ends of the purlins. The edge pressure block assemblies are fixed on the purlins and press the frames of the photovoltaic modules.

[0003] U-steel is a common component of photovoltaic support purlins. When the existing photovoltaic power station support purlins are U-steel, the end of the U-steel purlin exceeds the edge of the photovoltaic module and is not protected. Under the action of external forces, the end often deforms. Since the side pressure block assembly is close to the end of the U-steel, the opening of the U-steel is easily deformed, and the side pressure block assembly is very easy to fall off under the action of wind load, and the photovoltaic module loses its restraint and falls off, which is very dangerous. [Utility Model Content]

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic component fixing structure that can resist deformation of the U-steel end, thereby solving the problem that when the bracket purlin is U-steel, the U-steel end is deformed and the side pressure block assembly is easily detached under wind load.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A photovoltaic module fixing structure for resisting deformation of U-steel ends, comprising a U-steel purlin and an edge pressure block assembly arranged near the end of the U-steel purlin, the edge pressure block assembly comprising an edge pressure pad for pressing a frame of the photovoltaic module and a fastener for fixing the edge pressure pad to the U-steel purlin, the edge pressure block assembly also comprising an anti-deformation member, the anti-deformation member and the edge pressure pad are fixed together by the fastener, and the anti-deformation member is provided with an anti-deformation portion for resisting deformation of the end of the U-steel purlin.

[0007] Preferably, the anti-deformation part includes a fixing part overlapped and fixed with the edge pressure pad, and the anti-deformation part is a side protection plate extending downward from both sides of the fixing part, and the side protection plates on both sides are correspondingly located on the outside of the two side walls of the U-steel purlin to resist the outward deformation of the two side walls of the U-steel purlin.

[0008] Preferably, grooves are provided at the waists of both side walls of the U-steel purlin, and the lower edge of the side protection plate extends downward to the upper part of the groove and is provided with a shrinking edge that shrinks into the groove.

[0009] Preferably, the fastener is a pressure block bolt, the side pressure pad is fixed between the fixing portion and the U-steel purlin, and the pressure block bolt is fixed after passing downward through the fixing portion, the side pressure pad and the U-steel purlin.

[0010] Preferably, the pressing block bolt is a hexagon socket bolt; and / or, the pressing block bolt comprises a screw and a nut, and an anti-loosening gasket is provided between the screw and the fixing part and between the nut and the U-steel purlin.

[0011] Preferably, mounting holes cooperating with the pressure block bolts are reserved on the side pressure pad and the fixing portion, and waist-shaped grooves cooperating with the pressure block bolts are arranged at intervals along the length direction on the bottom wall of the U-steel purlin.

[0012] Preferably, the side pressure block assembly includes two pressure block bolts, and the two pressure block bolts are spaced apart along the length direction of the U steel purlin.

[0013] Preferably, the edge pressure pad is provided with a flat plate portion pressed onto the upper side of the U-steel purlin, a vertical portion vertically connected to the flat plate portion and fitted onto the outer side wall of the frame, and a pressing portion vertically connected to the vertical portion and pressed onto the upper side wall of the frame.

[0014] Preferably, the width of the pressing portion is greater than the width of the upper side wall of the frame, and the bottom surface of the pressing portion is provided with anti-slip convex patterns.

[0015] Preferably, the edge pressure pad is made of stainless steel or aluminum alloy profile; and / or the anti-deformation part is a sheet metal part.

[0016] The utility model adopts the above technical solution and has the following beneficial effects:

[0017] 1. Since the anti-deformation member is provided with an anti-deformation portion for resisting deformation of the end of the U-steel purlin, the deformation of the opening position of the end of the U-steel purlin can be prevented, thereby avoiding the side pressure block assembly from falling off under the action of wind load due to the deformation of the U-steel, resulting in the risk of the photovoltaic assembly losing its restraint and falling off.

[0018] Since the anti-deformation member and the side pressure pad are fixed together by fasteners, while resisting the deformation of the U-steel end, the overall structural strength of the side pressure block assembly can be increased, thereby reducing the probability of the side pressure block assembly falling off when the purlin is U-steel.

[0019] 2. Since the fixing part of the anti-deformation member is overlapped and fixed with the side pressure pad, the two are fastened together by fasteners, and the fixation is more reliable; since the side protection plates extend downward from both sides of the fixing part and are correspondingly located on the outside of the two side walls of the U-steel purlin, the protection range covers the U-steel opening position of the U-steel purlin which is most susceptible to deformation, thereby resisting the outward deformation of the two side walls of the U-steel purlin.

[0020] 3. The lower edge of the side protection plate extends downward to the upper part of the groove and is provided with a shrinking edge that shrinks into the groove, that is, the side protection plate covers the outer side of the U-steel opening, and provides targeted protection against deformation of the U-steel opening, thereby providing better protection effect.

[0021] 4. The fasteners are clamp bolts, which pass downward through the fixing part, the side clamp pad and the U-steel purlin to be fixed, so as to facilitate the installation of the side clamp assembly and ensure reliable fixation.

[0022] 5. The clamping bolts are hexagon socket bolts for easy operation. Anti-loosening washers are provided between the screw and the fixing part of the clamping bolts and between the nuts and the U-steel purlins to prevent the clamping bolts from loosening.

[0023] 6. Mounting holes that match the pressure block bolts are reserved on the side pressure pad and the fixed part. Waist-shaped grooves that match the pressure block bolts are arranged at intervals along the length direction of the bottom wall of the U-steel purlin. Therefore, during installation, the side pressure pad and the fixed part are overlapped, and after the mounting holes of the two are aligned, they can be connected with the pressure block bolts. After the screws of the pressure block bolts pass downward through the mounting holes reserved on the side pressure pad and the fixed part, they can be easily aligned with the waist-shaped grooves, which is convenient for installation.

[0024] 7. The two clamp bolts are spaced apart along the length of the U steel purlin to improve the reliability of fixation and avoid loosening and falling off.

[0025] 8. The shape of the edge pressure pad is in close contact with the component frame. Since the width of the pressing part is greater than the width of the upper side wall of the frame, the contact area is large. Furthermore, the bottom surface of the pressing part is provided with anti-slip convex patterns to prevent sliding.

[0026] 9. Since the edge pressure pad is an aluminum alloy profile, which is extruded, it can be industrialized and significantly reduce costs. It also has high strength, is not prone to rust, and has a long service life. The anti-deformation part is a sheet metal part, which has the advantages of light weight, high strength, low cost, and good performance in large-scale mass production.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0035] 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.

[0038] 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.

[0039] The purlins of the photovoltaic power station bracket are U steel, refer to Figures 1 to 4 As shown, the photovoltaic module 2 is installed on the U-steel purlin 5, and the photovoltaic module 2 has a frame 21. This embodiment provides a photovoltaic module fixing structure that resists deformation of the U-steel end, including the U-steel purlin 5 and an edge pressure block assembly arranged near the end of the U-steel purlin, the edge pressure block assembly includes an edge pressure pad 1 for pressing the photovoltaic module frame 21 and a fastener for fixing the edge pressure pad 1 to the U-steel purlin 5, the edge pressure block assembly also includes an anti-deformation member 3, the anti-deformation member 3 and the edge pressure pad 1 are fixed together by the fastener, and the anti-deformation member 3 is provided with an anti-deformation portion for resisting deformation of the U-steel purlin end.

[0040] The technical solution of this embodiment, since the anti-deformation member is provided with an anti-deformation portion for resisting deformation of the end of the U-steel purlin, can prevent the deformation of the opening position of the end of the U-steel purlin, thereby avoiding the side pressure block assembly from falling off under the action of wind load due to the deformation of the U-steel, resulting in the risk of the photovoltaic assembly losing restraint and falling off.

[0041] Since the anti-deformation member and the side pressure pad are fixed together by fasteners, while resisting the deformation of the U-steel end, the overall structural strength of the side pressure block assembly can be increased, thereby reducing the probability of the side pressure block assembly falling off when the purlin is U-steel.

[0042] Specifically, the anti-deformation member 3 includes a fixing portion 31 superimposed and fixed with the side pressure pad 1, and the anti-deformation portion is a side protection plate 32 extending downward from both sides of the fixing portion 31, and the side protection plates 32 on both sides are correspondingly located on the outside of the two side walls of the U-steel purlin to resist the outward deformation of the two side walls of the U-steel purlin. Since the fixing portion of the anti-deformation member is superimposed and fixed with the side pressure pad, the two are fastened together by fasteners, and the fixation is more reliable; since the side protection plates extend downward from both sides of the fixing portion and are correspondingly located on the outside of the two side walls of the U-steel purlin, the protection range covers the U-steel opening position of the U-steel purlin that is most easily deformed, thereby resisting the outward deformation of the two side walls of the U-steel purlin.

[0043] Furthermore, the waist of the two side walls of the U-steel purlin 5 is provided with a groove 51, and the lower edge of the side protection plate 32 extends downward to the upper part of the groove and is provided with a shrinking edge 321 shrinking into the groove. That is, the side protection plate covers the outer side of the U-steel opening, and provides targeted protection against deformation at the U-steel opening, so the protection effect is better.

[0044] It can be understood that the specific structure of the anti-deformation member 3 is not limited to the example of this embodiment.

[0045] In this embodiment, the fastener is a clamp bolt 4, the side clamp pad 1 is arranged between the fixing portion 31 and the U steel purlin 5, and the clamp bolt 4 is fixed after passing through the fixing portion 31, the side clamp pad 1 and the U steel purlin 5. The clamp bolt is used for fastening, which facilitates the installation of the side clamp assembly and is reliable in fixing.

[0046] Specifically, the clamp bolt 4 is a hexagon socket bolt; the clamp bolt 4 includes a screw 41 and a nut 42, and an anti-loosening gasket 43 is provided between the screw and the fixing part and between the nut and the U steel purlin. The hexagon socket bolt is used to facilitate operation. Since the anti-loosening gasket is provided between the screw and the fixing part of the clamp bolt and between the nut and the U steel purlin, the clamp bolt can be prevented from loosening. It is understandable that the fastener can be other common bolts, or fasteners such as rivets and buckles.

[0047] The side pressure pad 1 and the fixing part 31 are provided with mounting holes that match the pressure block bolt 4, namely the first mounting hole 111 and the second mounting hole 311, and the bottom wall of the U steel purlin is provided with waist-shaped grooves that match the pressure block bolts at intervals along the length direction. Therefore, during installation, the side pressure pad and the fixing part are overlapped, and after the mounting holes of the two are aligned, they can be connected with the pressure block bolts. After the screws of the pressure block bolts pass downward through the mounting holes reserved on the side pressure pad and the fixing part, they can be easily aligned with the waist-shaped grooves, which is convenient for installation.

[0048] Furthermore, the side pressing block assembly includes two pressing block bolts 4, and the two pressing block bolts 4 are spaced apart along the length direction of the U steel purlin 5, thereby improving the reliability of fixing and preventing loosening and falling off.

[0049] like Figure 1 and Figure 3 As shown, the edge pressure pad 1 is provided with a flat plate portion 11 pressed on the upper side of the U steel purlin, a vertical portion 12 vertically connected to the flat plate portion and in contact with the outer side wall of the frame, and a pressing portion 13 vertically connected to the vertical portion and pressed on the upper side wall of the frame. Specifically, the width of the pressing portion 13 is greater than the width of the upper side wall of the frame, and the bottom surface of the pressing portion is provided with anti-skid convex patterns 131. In this way, the shape of the edge pressure pad fits the assembly frame, and since the width of the pressing portion is greater than the width of the upper side wall of the frame, the contact area is large, and further, the bottom surface of the pressing portion is provided with anti-skid convex patterns to prevent sliding.

[0050] Specifically, the edge pressure pad 1 is made of stainless steel or aluminum alloy. The anti-deformation member 3 is a sheet metal part. The aluminum alloy profile is extruded to achieve industrialized production, significantly reduce costs, and has high strength, is not easy to rust, and has a long service life. The sheet metal part has the advantages of light weight, high strength, low cost, and good mass production performance.

[0051] 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.
