Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that, in the description of the present application, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the apparatus or elements to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.
Furthermore, it should be understood that the dimensions of the various elements shown in the figures are not drawn to actual scale, e.g., the thickness or width of some layers may be exaggerated relative to other layers for ease of description.
It should be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined or illustrated in one figure, no further detailed discussion or description thereof will be necessary in the following description of the figures.
The terms first, second and the like in the description and in the claims of embodiments of the application and in the above-described figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order, such as first and second parts, that are not necessarily required to be described in the context of their respective parts. It is to be understood that the components so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein.
Before understanding the embodiments of the present application, it is noted that in order to simplify the drawings in the present application so that a person skilled in the art can clearly understand the specific structures of the various parts proposed in the embodiments of the present application, threads of all parts (for example, the fastening bolt 6 and the threaded rod 62, etc. hereinafter) are omitted in the drawings of the present application.
In order to solve the technical problem that the fastening bolt of the outdoor photovoltaic bracket has loosening risk, which is proposed in the background art, the application provides an embodiment of a photovoltaic bracket connecting structure, wherein the photovoltaic bracket comprises a first part and a second part, and the first part and the second part are connected through the fastening bolt 6. In this embodiment, the first part and the second part may be any parts of the photovoltaic bracket that need to be connected by fastening bolts, for example, if the first part is a metal corrugated board 2, the second part may be the supporting member 5. Of course, if the first part is the support 5, the second part may also be the metal corrugated sheet 2. Or if the first part is a metal corrugated board 2, the second part may be a cross beam 1. Of course, if the first part is the cross beam 1, the second part may also be the metal corrugated board 2, which will not be described in detail later.
In the present embodiment, the photovoltaic bracket connection structure includes a first limit bar 71, a second limit bar 72, and a fastening bolt 6. As shown in fig. 3 and 4, the first stop bar 71 has a first plane, and the second stop bar 72 has a second plane opposite to the first plane. And the first and second stopper bars 71 and 72 have elasticity or plasticity. As shown in fig. 5 to 7, the fastening bolt 6 has a third plane 63 and a fourth plane 64. In use, as shown in fig. 8 and 9, the third plane 63 is opposite the first plane and the fourth plane 64 is opposite the second plane for restricting rotation of the fastening bolt 6. It is noted that the fastening bolt 6 cannot be rotated during use under the restriction between the first plane, the second plane, the third plane 63 and the fourth plane 64. If the fastening bolt 6 cannot be rotated, the fastening bolt 6 must not be loosened during long-term use. That is, the embodiment of the present application can restrict the rotation of the fastening bolt 6, that is, can prevent the fastening bolt 6 from loosening, by the first plane on the first stopper 71 and the second plane on the second stopper 72, in cooperation with the third plane and the fourth plane on the fastening bolt 6. In the long-term use process, if the fastening bolt 6 is difficult to loosen, the structural strength of the photovoltaic support is reduced due to the loosening of the fastening bolt, and the phenomenon that the photovoltaic assembly falls down to be damaged or a safety accident is caused is difficult to occur.
In order to further define the position of the fastening bolt 6, the fastening bolt 6 is prevented from rotating. In one embodiment of the present application, as shown in fig. 4 and 9, a threaded hole 73 is formed between the first limit bar 71 and the second limit bar 72. As shown in fig. 4, the photovoltaic bracket connection structure further includes a screw 9, and the screw 9 is matched with the threaded hole 73. In use, the screw 9 is screwed into the threaded hole 73 such that the tip of the screw 9 abuts against the fastening bolt 6, and the position of the fastening bolt 6 can be further defined.
It should be noted that, in the present embodiment, the first and second stopper bars 71 and 72 have elasticity or plasticity, that is, the first and second stopper bars 71 and 72 can be elastically deformed or plastically deformed, that is, the portion (for example, the nut 61 hereinafter) of the fastening bolt 6 having the third and fourth planes 63 and 64 can be placed between the first and second stopper bars 71 and 72 without damaging the first and second stopper bars 71 and 72 during subsequent use, so that the first and second stopper bars 71 and 72 can limit the fastening bolt 6.
In the embodiment of the present application, no limitation is made to the shape and configuration of the first and second stopper bars 71 and 72. For example, the first and second stopper bars 71 and 72 may have a rectangular bar shape or an elongated bar shape as shown in fig. 4. It should be noted that, with respect to the rectangular bar shape, since the bottoms of the first and second limit bars 71 and 72 of the rectangular bar shape as shown in fig. 4 are arc-shaped, it is difficult for the bottoms of the first and second limit bars 71 and 72 to form stress concentration, that is, when the portion of the fastening bolt 6 having the third and fourth planes 63 and 64 is screwed between the first and second limit bars 71 and 72, the first and second limit bars 71 and 72 are not broken to be separated from the first part (for example, the supporting member 5 as shown in fig. 4 or the metal corrugated sheet 2 as shown in fig. 8) due to stress concentration.
In embodiments of the present application, the first, second, third and fourth planes 63, 64 may cooperate in any reasonable manner to limit rotation of the fastening bolt 6. For example, in one embodiment of the present application, the first, second, third and fourth planes 63, 64 may be mated as shown in fig. 12. In order to be able to stably position the fastening bolt 6, the first plane and the second plane may be parallel, i.e. the third plane 63 and the fourth plane 64 may be parallel, as shown in fig. 11.
It should be noted that, in an application scenario where the first plane and the second plane are parallel, in order to ensure that the fastening bolt 6 is easily mounted between the first limit bar 71 and the second limit bar 72, a distance between the first plane and the second plane (i.e., a distance S1 shown in fig. 11) may be equal to or greater than a distance between the third plane 63 and the fourth plane 64 (i.e., a distance S2 shown in fig. 11). It will be readily appreciated that if the distance between the first plane and the second plane is equal to or greater than the distance between the third plane 63 and the fourth plane 64, then, after installation, the third plane 63 on the fastening bolt 6 is in contact with or has a gap from the first plane on the first stop strip 71, and the fourth plane 64 on the fastening bolt 6 is also in contact with or has a gap from the second plane on the second stop strip 72. Compared with the application scene that the fastening bolt 6 is abutted against the first limit bar 71 or the second limit bar 72 after installation, the application scene that the fastening bolt 6 is in contact with the first limit bar 71 or the second limit bar 72 or has a gap after installation is more convenient for installing the fastening bolt 6.
It should be noted that, in the application scenario where the first plane and the second plane are parallel, the combination of the first plane, the second plane, the third plane 63, and the fourth plane 64 can perform stable limiting on the fastening bolt 6. The distance between the first plane and the second plane (i.e., the distance S1 shown in fig. 11) must be smaller than the maximum outer diameter of the fastening bolt 6 (i.e., the outer diameter S3 shown in fig. 11) around the third plane 63 and the fourth plane 64 in the circumferential direction. It will be readily appreciated that if the distance between the first and second planes is less than the maximum outer diameter of the fastening bolt 6 in the circumferential direction about the third and fourth planes 63, 64, the fastening bolt 6 is difficult to rotate under the restriction of the first and second planes.
In the embodiment of the present application, there is no limitation in the shape and configuration of the fastening bolt 6. For example, the fastening bolt 6 may be a threaded rod having only a thread. To facilitate rotation of the fastening bolt 6, in one embodiment of the present application, the fastening bolt 6 may include a threaded rod 62 and a nut 61. As shown in fig. 5 to 7, the nut 61 is provided at one end of the threaded rod 62, and the third plane 63 and the fourth plane 64 are provided to the nut 61. By the arrangement of the screw cap 61, the user can rotate the fastening bolt 6 by means of the tool through the screw cap 61.
In the embodiment of the present application, the shape and configuration of the nut 61 are not limited, and it is only required to have the third plane 63 and the fourth plane 64, for example, the nut 61 may have a hexagonal block structure as shown in fig. 5, or a square block structure as shown in fig. 6.
To further facilitate the rotation of the fastening bolt 6, in an embodiment of the application the nut 61 may be provided with a first limit groove 65. The axes of the nut 61, the threaded rod 62 and the first limit groove 65 are all coincident. By the arrangement of the first limit groove 65, the user can rotate the fastening bolt 6 by means of a tool through the first limit groove 65.
In the embodiment of the present application, the shape and the structure of the first limiting groove 65 are not limited, and only need to be capable of rotating in cooperation with a certain tool. For example, as shown in fig. 5, the first limiting groove 65 may be in a shape of a regular hexagon groove, and the fastening bolt 6 may be rotated by means of an internal hexagonal wrench in cooperation with the first limiting groove 65 during use. Or the first limiting groove 65 can also be in a cross groove shape as shown in fig. 7, and the fastening bolt 6 can be rotated by means of a cross screwdriver matched with the first limiting groove 65 during use.
It should be appreciated that in embodiments of the present application, the first and second stop bars 71, 72 may be disposed at any suitable location on the photovoltaic bracket. In order to facilitate fixing the first and second limiting bars 71, 72, the first and second limiting bars 71, 72 may be disposed on a first part, which may be a metal corrugated board 2, a supporting member 5, a cross beam 1, etc. in the photovoltaic bracket. In this embodiment, the fastening bolt 6 is screwed with the second part.
In a specific embodiment of the present application, as shown in fig. 8, the first limit bar 71 and the second limit bar 72 may be integrally provided on the metal corrugated board 2 (i.e., the first part), and the beam 1 (i.e., the second part) may be internally provided with an internal thread groove (not shown), and in use, the beam 1 and the metal corrugated board 2 are connected together through the fastening bolt 6 and the internal thread groove. The fastening bolt 6 is hard to rotate loose due to the first and second stopper bars 71 and 72 and the stopper action.
It should be noted that during long-term use, disassembly repair or maintenance of the photovoltaic bracket or the photovoltaic module 3 is required. In the application scenario that the internal thread groove is arranged on the second part, if the internal thread groove on the second part is damaged due to frequent installation and disassembly, the whole second part needs to be replaced, and the cost is high. In order to reduce the cost of use, in an embodiment of the application, the photovoltaic bracket connection structure further comprises a nut 8. As shown in fig. 9, in use, the cross member 1 and the metal corrugated sheet 2 can be connected by the nuts 8 and the fastening bolts 6. In the application scenario of frequently dismantling the photovoltaic bracket or the photovoltaic module 3, even if the nut 8 or the fastening bolt 6 is damaged, the replacement cost is low.
It is easy to understand that in the application scenario where the nut 8 is used, if only the fastening bolt 6 is limited, but the nut 8 is not limited, the fastening bolt 6 still has a possibility of loosening. In the embodiment of the application, in order to limit the nut 8, as shown in fig. 9, the second part is further provided with a profiling groove 11, the profiling groove 11 being adapted to the nut 8.
It should be noted that in the embodiment of the present application, the matching of the profiling groove 11 with the nut 8 means that the nut 8 can be put into the profiling groove 11, and the nut 8 cannot be rotated after the nut 8 is put into the profiling groove 11. For example, the profiling groove 11 may be a regular hexagonal groove if the nut 8 is in the form of a regular hexagonal block, or the profiling groove 11 may be a square groove if the nut 8 is in the form of a square block, etc., which will not be described in detail herein.
It should be clear that if the profiled groove 11 is provided in the second part, the structural strength of the second part may be affected. In order to avoid affecting the structural strength of the second part, in one embodiment of the present application, as shown in fig. 10, a plastic ring 81 may be provided on the nut 8, the plastic ring 81 being capable of plastic deformation, the plastic ring 81 may be a metal ring or a plastic ring, etc. The fastening bolt 6 is provided with a second limiting groove 621, and the extending direction of the second limiting groove 621 is parallel to the axial direction of the fastening bolt 6.
In use, if the fastening bolt 6 and the nut 8 are connected in place, the plastic ring 81 is deformed by an external force and pressed into the second limiting groove 621. It is easy to understand that if the plastic ring 81 is pressed into the second limiting groove 621, the nut 8 is hard to rotate under the restriction of the plastic ring 81 and the second limiting groove 621. If the nut 8 cannot be rotated, the tightening bolt 6 is difficult to loosen.
It is clear that in the embodiment of the photovoltaic bracket connection structure provided by the application, the fastening bolt can be limited to rotate by matching the first plane on the first limit bar and the second plane on the second limit bar with the third plane and the fourth plane on the fastening bolt, namely loosening of the fastening bolt can be avoided. In the long-term use process, if the fastening bolt is difficult to loosen, the strength of the photovoltaic support structure is reduced due to the loosening of the fastening bolt, and the phenomenon that the photovoltaic module falls down to be damaged or causes safety accidents is difficult to occur.
After introducing the photovoltaic bracket connection structure provided by the embodiment of the present application, a photovoltaic bracket provided by the present application is described below, and specifically, the photovoltaic bracket includes the photovoltaic bracket connection structure provided by any one of the embodiments.
In a specific embodiment of the application, as shown in fig. 1, the photovoltaic bracket further comprises a cross beam 1 and a metal corrugated sheet 2. The metal corrugated sheet 2 is connected to the cross member 1, and the metal corrugated sheet 2 has metal corrugations 4.
In order to increase the strength of the metal corrugations 4 to increase the overall strength of the metal corrugated sheet 2, in one embodiment of the present application, the photovoltaic bracket further includes at least one support 5, as shown in fig. 2, each support 5 being disposed on the metal corrugations 4.
In the embodiment of the present application, the supporting member 5 mainly supports the metal corrugation 4 to enhance the overall strength of the metal corrugated sheet 2. In the present embodiment, the shape and the configuration of the support 5 are not limited at all, and for example, the support 5 may have a rod-like structure or a sheet-like structure as shown in fig. 4.
It is to be clear that in the present embodiment, as shown in fig. 1 and 3, the metal corrugation 4 includes a first inclined portion 41, a corrugation bottom portion 42, and a second inclined portion 43 which are connected in order. The support 5 is connected at one end to the first inclined portion 41 and at the other end to the second inclined portion 43 in use. In order to avoid the mismatching of the self angle of the supporting member 5 and the angle between the first inclined portion 41 and the corrugated bottom 42 or the angle between the second inclined portion 43 and the corrugated bottom 42 in the metal corrugated 4, the supporting member 5 and the metal corrugated 4 form a larger internal stress after the supporting member 5 is mounted on the metal corrugated 4. In one embodiment of the present application, as shown in fig. 13, the support 5 may include a support piece 51 and a connection piece 52, and the support piece 51 and the connection piece 52 are hinged.
It should be clear that in the present embodiment, the supporting sheet 51 mainly functions to support the metal corrugations 4, and the connecting sheet 52 mainly functions to form a connection with the first inclined portion 41 or the second inclined portion 43. Because the supporting piece 51 and the connecting piece 52 are hinged, in the use process, the angles of the supporting piece 51 and the connecting piece 52 can be adjusted according to the angles of the first inclined part 41 and the corrugated bottom 42 or the angles of the second inclined part 43 and the corrugated bottom 42 in the metal corrugated 4, so that the supporting piece 5 can be suitable for the metal corrugated 4 with different angles.
It should be noted that the embodiment of the photovoltaic bracket provided by the application has the photovoltaic bracket connection structure provided by the embodiment, so that the photovoltaic bracket can limit the rotation of the fastening bolt by matching the first plane on the first limit bar and the second plane on the second limit bar with the third plane and the fourth plane on the fastening bolt, i.e. can avoid loosening of the fastening bolt. In the long-term use process, if the fastening bolt is difficult to loosen, the strength of the photovoltaic support structure is reduced due to the loosening of the fastening bolt, and the phenomenon that the photovoltaic module falls down to be damaged or causes safety accidents is difficult to occur.
Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined in the appended claims and their equivalents.
