Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and specifically to a photovoltaic bracket and a metal plate thereof. Background Art

[0002] Photovoltaic brackets are special brackets used to install and support photovoltaic modules. They are generally customized according to the size and shape of photovoltaic modules to meet the installation requirements in different environments. Generally, photovoltaic brackets are fixed on the ground, roof or other structures to keep the photovoltaic modules at a certain tilt angle to maximize the reception of solar radiation. Figure 1 As shown, it includes a crossbeam and a metal plate. When in use, the crossbeam and the metal plate are connected by bolts, and then the photovoltaic component is set on the metal plate. The metal plate can support the photovoltaic component to keep a certain tilt angle of the photovoltaic component.

[0003] It should be clear that in sparsely populated areas (for example, deserts or wastelands), the thickness of the metal plate is generally set to a critical thickness in order to save costs. Most metal plates at the critical thickness can ensure good structural strength within their service life, that is, they can stably support photovoltaic modules. Even if the structural strength of a small number of metal plates deteriorates and cannot stably support photovoltaic modules, causing the photovoltaic modules to fall off, it will not cause safety accidents due to its location in sparsely populated areas. It is easy to understand that if such photovoltaic brackets are used in areas with dense populations (for example, roofs or bus station tops, etc.), the structural strength of the metal plates is prone to deterioration during long-term use, leading to safety accidents. If the photovoltaic bracket is redesigned for areas with dense populations, the cost will be higher. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] It should be noted that, in the description of the present application, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0039] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0040] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.

[0041] In order to solve the technical problem of low structural strength of the flat metal plate mentioned in the background art, the present application proposes an embodiment of a metal plate, specifically, the metal plate comprises a metal corrugation 4 and at least one supporting member 5 arranged on the metal corrugation 4. Figure 2As shown, the metal corrugated sheet 4 includes a first inclined portion 41, a corrugated bottom 42, and a second inclined portion 43 connected in sequence. The first end of each support member 5 is connected to the first inclined portion 41, and the second end of each support member 5 is connected to the second inclined portion 43. In this embodiment, the support member 5 is at least used to support the first inclined portion 41 and the second inclined portion 43, thereby preventing the first inclined portion 41 and the second inclined portion 43 from being deformed after being subjected to external force, that is, the support member 5 is at least used to limit the relative displacement of the first inclined portion 41 and the second inclined portion 43.

[0042] It should be clear that the embodiments of the present application provide metal corrugations on the metal plate, and support members are provided in the metal corrugations, and the support members can support the first inclined portion and the second inclined portion of the metal corrugations to increase the overall structural strength of the metal corrugations. Compared with the flat metal plates in the prior art, the structural strength of the metal plates in the present application is greatly increased. Without changing the thickness of the plate, the metal plate is applied to photovoltaic brackets with dense crowds, which can effectively prevent the photovoltaic components from falling off due to insufficient support force, thereby reducing the probability of safety accidents.

[0043] In the embodiment of the present application, there is no restriction on the shape and structure of the first inclined portion 41, the corrugated bottom 42 and the second inclined portion 43. For example, the first inclined portion 41, the corrugated bottom 42 and the second inclined portion 43 can be in the shape of an arc-shaped sheet. In order to facilitate the forming of the metal corrugated 4, in the embodiment of the present application, the first inclined portion 41, the corrugated bottom 42 and the second inclined portion 43 can be as follows Figure 2 and Figure 3 It is easy to understand that the flat sheet-shaped first inclined portion 41, the corrugated bottom 42 and the second inclined portion 43 are easy to be formed by sheet calendering or stamping.

[0044] In the embodiment of the present application, the support member 5 can be arranged inside the metal corrugated sheet 4 in any suitable manner. For example, if the first inclined portion 41 or the second inclined portion 43 is susceptible to external force in a certain direction during long-term use, the extension direction of the support member 5 can be made parallel to the direction of the force, so that the support member 5 can stably support the first inclined portion 41 or the second inclined portion 43. It should be noted that in order to ensure that the support force provided by the support member 5 to the first inclined portion 41 and the second inclined portion 43 is uniform and equal, in one embodiment of the present application, it can be as follows Figure 3 As shown, the extension direction of the support member 5 can be parallel to the width of the corrugated bottom 42 (i.e., as shown in FIG. Figure 3 The width in b) direction.

[0045] In the embodiment of the present application, there is no limitation on the shape and structure of the support member 5. It is only necessary that the support member 5 can provide support force for the first inclined portion 41 and the second inclined portion 43. For example, in the embodiment of the present application, the support member 5 may include: Figures 3 to 5 The support rod 51 shown, or the support member 5 may include Figure 6 The support sheet 54 is shown.

[0046] In the embodiment of the present application, the support member 5 can be connected to the first inclined portion 41 or the second inclined portion 43 in any suitable manner. Figure 3 As shown, the support member 5 is welded or integrally connected with the first inclined portion 41 and the second inclined portion 43. Alternatively, the support member 5 can be detachably connected with the first inclined portion 41 and the second inclined portion 43 through a connecting member as described below.

[0047] It should be noted that in the embodiments of the present application, a connecting member may be provided only at the first end of the support member 5 so that the first end of the support member 5 can be connected to the first inclined portion 41 through the connecting member. A connecting member may also be provided only at the second end of the support member 5 so that the second end of the support member 5 can be connected to the second inclined portion 43 through the connecting member. A connecting member may also be provided at both the first end of the support member 5 and the second end of the support member 5. In order to avoid redundancy, in the subsequent embodiments or drawings, only the connection relationship between the first inclined portion 41 and the connecting member is introduced, or only the connection relationship between the second inclined portion 43 and the connecting member is introduced. It is easy to understand that in the embodiment in which only the connection relationship between the first inclined portion 41 and the connecting member is introduced, the connection relationship is also applicable to the second inclined portion 43 and the connecting member; of course, in the embodiment in which only the connection relationship between the second inclined portion 43 and the connecting member is introduced, the connection relationship is also applicable to the first inclined portion 41 and the connecting member, and no repetitive description will be made later.

[0048] In the embodiment of the present application, there is no restriction on the shape and structure of the connecting member, as long as the connecting member can make the inclined portion (the first inclined portion 41 or the second inclined portion 43) form a detachable connection with the support member 5. For example, the connecting member can be as follows: Figure 4 The threaded rod 52 shown in the figure can be connected to the inclined portion by a nut when in use. Alternatively, the connecting member can be as follows Figure 6 The connecting piece 55 shown in the figure has at least one connecting hole, and when in use, the connecting piece 55 and the inclined portion can be connected by bolts or rivets. Alternatively, the connecting member can be as follows Figure 5 As shown, the connecting member includes a connecting ring 56 and a connecting rod 53. One end of the connecting rod 53 is connected to the connecting ring 56, and the other end of the connecting rod 53 is connected to the supporting member 5. When in use, the connecting ring 56 and the inclined portion can be connected by bolts or rivets.

[0049] It is easy to understand that if the support member 5 can form a detachable connection with both the first inclined portion 41 and the second inclined portion 43, it is convenient to adjust the position of the support member 5 according to the stress conditions of the metal corrugated sheet 4 during use, or to replace the support member 5 with a different mechanical strength.

[0050] In the embodiment of the present application, there is no restriction on the connection method between the support member 5 and the connecting member. For example, the support member 5 and the connecting member can be fixedly connected. It is easy to understand that if the support member 5 and the connecting member are fixedly connected, in order to make the support member 5 compatible with the metal corrugated sheet 4, the angle formed between the support member 5 and the connecting member (i.e., Figure 7 The angle C shown in FIG. 4 may be the angle formed by the corrugated bottom 42 and the first inclined portion 41 or the second inclined portion 43 (ie, Figure 7 The angle D) shown needs to be adapted.

[0051] In this embodiment, the support member 5 is adapted to the metal corrugated sheet 4, which means that after the support member 5 is connected to the metal corrugated sheet 4, there will be no internal stress between the support member 5 and the metal corrugated sheet 4 due to the connection. It is easy to understand that if there is internal stress between the support member 5 and the metal corrugated sheet 4 due to the connection, the internal stress will cause the support member 5 or the metal corrugated sheet 4 to deform during long-term use, thereby affecting the structural strength of the metal corrugated sheet 4 ... Figure 7 As shown, if the angle C is equal to the angle D, the internal stress formed after the support member 5 is connected to the metal corrugated sheet 4 is 0, that is, the internal stress reaches the minimum. That is to say, in the embodiment of the present application, the angle formed between the support member 5 and the connecting member can be adapted to the angle formed by the corrugated sheet bottom 42 and the first inclined portion 41 or the second inclined portion 43, which means that the two angles are close to being equal.

[0052] In order to make the support member 5 applicable to the metal corrugated sheet 4 at any angle, in one embodiment of the present application, the support member 5 can be as follows: Figures 4 to 6 As shown, the support member 5 can be hinged with the connecting member. It is easy to understand that if the support member 5 is hinged with the connecting member, the angle between the support member 5 and the connecting member can be adjusted according to the angle between the inclined portion of the metal corrugated sheet 4 and the corrugated bottom 42, so that after the support member 5 is connected to the metal corrugated sheet 4 at any angle, the internal stress formed between the support member 5 and the metal corrugated sheet 4 due to the connection is small.

[0053] As can be seen from the foregoing, the connectors in the above embodiments all have parts (e.g., threaded rods 52 or bolts, etc.) that need to pass through the metal plate 2. In order to facilitate the adjustment of the actual position of the support member 5 during use, in the embodiments of the present application, a plurality of through holes (not shown in the figure) may be provided on the first inclined portion 41 and / or the second inclined portion 43, and each through hole is arranged in sequence along the extension direction of the metal corrugated plate 4. It is easy to understand that since the through holes are preset in the inclined portion, the parts in the connector may be passed through the corresponding through holes according to the actual position of the support member 5 during use, so that the support member 5 can be connected to the metal corrugated plate 4.

[0054] It is easy to understand that if through holes are opened on the metal plate 2, and the more through holes there are, the more serious the decrease in the structural strength of the metal plate 2 will be. In order to avoid the decrease in the structural strength of the metal plate 2, in one embodiment of the present application, Figure 8 As shown, the first inclined portion 41 and / or the second inclined portion 43 may be provided with a T-shaped slide rail 21, the extension direction of the T-shaped slide rail 21 is parallel to the extension direction of the metal corrugated sheet 4, and a slider 6 is provided in the T-shaped slide rail 21. The connecting member further includes a fastening bolt 7, which is threadedly connected to the slider 6.

[0055] When using, Figure 8 As shown, the spacing between the support member 5 and the slider 6 can be reduced by rotating the fastening bolt 7. If the spacing between the support member 5 and the slider 6 is reduced, the support member 5 and the slider 6 can clamp the T-shaped slide rail 21, that is, the support member 5 can be stably connected to the inclined portion (that is, the first inclined portion 41 or the second inclined portion 43). It is easy to understand that in this embodiment, the fastening bolt 7 does not need to pass through the metal plate 2, that is, there is no need to set a through hole on the metal plate 2, that is, the structural strength of the metal plate 2 can be ensured.

[0056] In another embodiment of the present application, Fig. 9 As shown, the support member 5 and the slider 6 can be an integrated structure. When in use, the end of the fastening bolt 7 can conflict with the inner wall of the T-shaped slide rail 21. It is easy to understand that if the end of the fastening bolt 7 can conflict with the inner wall of the T-shaped slide rail 21 when in use, then under the reaction force, the slider 6 can also conflict with the inner wall of the T-shaped slide rail 21. In other words, under the action of the resistance force formed between the slider 6 and the T-shaped slide rail 21, the support member 5 can form a stable connection with the inclined portion. In this embodiment, the fastening bolt 7 does not need to pass through the metal plate 2, which can ensure the structural strength of the metal plate 2.

[0057] It should be clear that in the embodiment of the present application, through the provision of the T-shaped slide rail 21, the user can adjust the position of each support member 5 in the metal corrugation 4 as required, so that the metal corrugation 4 can be adjusted to different structural strengths according to the usage. For example, at the position where a larger supporting force is required in the metal corrugation 4, a few more support members 5 can be set; at the position where a smaller supporting force is required in the metal corrugation 4, a few less support members 5 can be set. In the embodiment of the present application, the extension length of the T-shaped slide rail 21 can be equal to the extension length of the metal corrugation 4. In order to save costs, in one embodiment of the present application, the T-shaped slide rail 21 can be set only at the position on the metal corrugation 4 where the support member 5 may be installed. That is to say, in this embodiment, if Fig.10 As shown, the T-shaped slide rail 21 may have multiple sections, and each section of the T-shaped slide rail 21 is sequentially distributed along the extension direction of the metal corrugated sheet 4. It is easy to understand that, relative to the T-shaped slide rail 21 whose extension length is equal to the length of the metal corrugated sheet 4, Fig.10 The segmented T-shaped slide rail 21 shown can reduce the total length of the T-shaped slide rail 21 , that is, reduce the production cost.

[0058] It should be clear that in the embodiment of the metal plate proposed in the present application, metal corrugations are arranged on the metal plate, and support members are arranged in the metal corrugations, and the support members can support the first inclined portion and the second inclined portion of the metal corrugations to increase the overall structural strength of the metal corrugations. Compared with the flat metal plate in the prior art, the structural strength of the metal plate in the present application is greatly increased.

[0059] After introducing the metal plate proposed in the embodiment of the present application, a photovoltaic bracket proposed in the embodiment of the present application is introduced below. The photovoltaic bracket includes the metal plate proposed in any one of the above embodiments.

[0060] Specifically, the photovoltaic bracket can be Figure 2 As shown, it includes a crossbeam 1 and a metal plate 2. Each metal plate 2 is connected to the crossbeam 1. When in use, the photovoltaic assembly 3 can be arranged on the metal plate 2. Since the metal corrugation 4 is arranged on the metal plate 2 in this embodiment, and the support member 5 is arranged in the metal corrugation 4, the support member can support the first inclined portion 41 and the second inclined portion 43 of the metal corrugation 4 to increase the overall structural strength of the metal corrugation 4. Compared with the flat metal plate in the prior art, the structural strength of the metal plate 2 in the present application is greatly increased.

[0061] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
