DETAILED DESCRIPTION

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] The terms "first", "second", etc. in the description and claims of the embodiments of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, such as the first chute and the second chute proposed below, which belong to different chute. It should be understood that the chute used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that shown or described herein.

[0028] Before understanding the embodiments of the present application, it should be noted that in order to simplify the drawings in the present application so that technicians in this field can clearly understand the specific structures of various parts proposed in the embodiments of the present application, the threads of all parts (for example, the fastening bolts 23 mentioned below, etc.) are omitted in the drawings of the present application.

[0029] In order to solve the technical problem that if holes are preset on the beam 1 and the metal plate 2, and there are errors in the preset holes, it is difficult to install the photovoltaic bracket and it is difficult to adjust the actual position of the metal plate. Figure 2 As shown, it includes a crossbeam 1, a metal plate 2, an auxiliary frame 4 and a support assembly 5. Figure 2 and Figure 3 As shown, the auxiliary frame 4 is arranged on one side of the metal plate 2, and the auxiliary frame 4 is provided with a first slide groove 42. Figure 2 and Figure 4 As shown, the support assembly 5 includes a first sliding block 53 , and the first sliding block 53 forms a sliding connection with the first sliding groove 42 along a first direction, and the first direction is parallel to the extension direction of the beam 1 .

[0030] It should be noted that, in the prior art, the metal plate 2 is fixedly installed on the crossbeam 1 with bolts. If the position between the metal plate 2 and the crossbeam 1 needs to be adjusted, the bolts must be removed first, then the metal plate 2 is removed, and then the crossbeam 1 is re-drilled. Then, the metal plate 2 is re-installed in the new hole position with bolts. The entire process of changing the position is particularly cumbersome.

[0031] It should be clear that, in this embodiment, compared with the bolt connection between the metal plate 2 and the cross beam 1, in this embodiment, the auxiliary frame 4 and the support assembly 5 can slide relative to each other through the first slide groove 42 and the first slider 53. In other words, the relative position between the metal plate 2 and the cross beam 1 can be adjusted through the first slide groove 42 and the first slider 53. In other words, during the installation of the photovoltaic bracket, the installation position of the photovoltaic assembly 3 can be flexibly changed, and the steps for changing the position are simple and easy to operate.

[0032] In order to avoid relative displacement between the metal plate 2 and the beam 1 due to natural factors (for example, wind and rain, etc.), in an embodiment of the present application, the first slide groove 42 and the first slider 53 can be interference fit, that is, the friction between the first slide groove 42 and the first slider 53 is large, thereby making it difficult for natural factors to move the metal plate 2.

[0033] In order to facilitate the user to move the metal plate 2 , in one embodiment of the present application, a locking mechanism is installed between the auxiliary frame 4 and the first slider 53 , and the locking mechanism is used to limit the sliding of the auxiliary frame 4 relative to the first slider 53 .

[0034] In the embodiments of the present application, there is no limitation on the locking mechanism, as long as it can lock the positions of the auxiliary frame 4 and the support assembly 5. Figure 2 As shown, the limiting mechanism includes a first bolt, and at least one first threaded hole is opened on the side of the auxiliary frame 4, and the first threaded hole is connected to the first slide groove 42. When the auxiliary frame 4 and the support assembly 5 are locked, the first bolt is inserted into the first threaded hole and then tightened so that the end of the first bolt can conflict with the first slider 53. Since the end of the first bolt can conflict with the first slider 53, the position of the auxiliary frame 4 and the first slider 53 is locked under the limiting action of the first bolt. If unlocking is required later, it is only necessary to loosen the first bolt.

[0035] It should be noted that, in this embodiment, there is no specific restriction on the number of the first threaded holes as long as it is reasonable.

[0036] As another embodiment of the present application, the limiting mechanism may include a first magnetic block and a second magnetic block (not shown in the figure) that are attracted to each other, wherein at least one first mounting groove for mounting the first magnetic block is provided on the inner top wall of the first slide groove 42, and at least one second mounting groove for mounting the second magnetic block is provided on the upper surface of the first slider 53. The first magnetic block is embedded and fixed in the first mounting groove on the inner top wall of the first slide groove 42, and the second magnetic block is embedded and fixed in the second mounting groove on the upper surface of the first slider 53. The mutual attraction of the first magnetic block and the second magnetic block is utilized to limit the connection of the auxiliary frame 4 and the support assembly 5.

[0037] Exemplarily, a second magnetic block is installed in the second mounting groove on the upper surface of each first sliding block 53, and at least one group of second mounting grooves is opened on the inner wall of the first sliding groove 42. Each group of second mounting grooves includes two second mounting grooves, and the second mounting grooves are respectively close to the left and right sides of the first sliding groove 42.

[0038] It should be understood that there are many possibilities for the number and specific positions of the first magnetic blocks and the second magnetic blocks, and no specific limitation is imposed herein.

[0039] In this way, when the auxiliary frame 4 and the supporting assembly 5 are connected, the first sliding groove 42 of the auxiliary frame 4 is first aligned with one end of the top of the supporting assembly 5, and then the auxiliary frame 4 is pushed to make the auxiliary frame 4 slide relative to the supporting assembly 5. When the first magnetic block on the auxiliary frame 4 moves to the specified position, the first magnetic block is attracted by the corresponding second magnetic block, so that the auxiliary frame 4 and the supporting assembly 5 are connected.

[0040] In the embodiment of the present application, there is no restriction on the shape and structure of the auxiliary frame 4, and it only needs to have the first slide groove 42. For example, the auxiliary frame 4 can be a square strip frame. In order to facilitate the connection between the auxiliary frame 4 and the metal plate 2, in one embodiment of the present application, as shown in FIG. Figure 3 As shown, the auxiliary frame 4 further includes a base plate 41 and a support plate 43 which are connected in sequence. The support plate 43 is vertically arranged on the upper surface of the base plate 41. The first slide groove 42 extends from one end of the base plate 41 to the other end thereof. Figure 3 As shown, the cross section of the entire first slide groove 42 is T-shaped. When the first slider 53 of the support assembly 5 is inserted into the first slide groove 42, the first slider 53 and the first slide groove 42 are highly matched to ensure the stability between the support assembly 5 and the auxiliary frame 4.

[0041] It should be explained that, in this embodiment, the length and number of the auxiliary frame 4 and the support assembly 5 are not specifically limited, and there are multiple possibilities. For example, the auxiliary frame 4 and the support assembly 5 are one-to-one corresponding, and the lengths of the auxiliary frame 4 and the support assembly 5 are substantially the same. Alternatively, the length of the support assembly 5 is greater than the length of the auxiliary frame 4, and multiple auxiliary frames 4 are slidably mounted on each support assembly 5. Alternatively, the length of the support assembly 5 is less than the length of the auxiliary frame 4, that is, multiple support assemblies 5 are slidably connected to one auxiliary frame 4 at the same time.

[0042] In the embodiment of the present application, there is no restriction on the shape and structure of the support assembly 5 , that is, the support assembly 5 only needs to have the first sliding block 53 .

[0043] In the embodiments of the present application, Figure 4 As shown, the support assembly 5 further includes a bottom plate 51, a support plate 52 and a first slider 53 which are connected in sequence. The support plate 52 is vertically arranged on the upper surface of the first slider 53, the first slider 53 is vertically arranged on the top of the support plate 52, and the first slider 53 is parallel to the bottom plate 51.

[0044] In this embodiment, in order to ensure the structural strength of the support assembly 5, the bottom plate 51, the support plate 52, and the first slider 53 are all made of metal (for example, aluminum alloy or steel) plates. The bottom plate 51, the support plate 52, and the first slider 53 can be machined and integrally formed.

[0045] In order to ensure that the first slider 53 has a certain flexibility, so that a flexible connection can be formed between the metal plate 2 and the crossbeam 1, such as Figure 4 As shown, a groove 54 may be provided at the top of the first slider 53, and the groove 54 penetrates the first slider 53 along the first direction. It should be understood that the groove 54 allows the first slider 53 to have a certain deformation space under the action of an external force. If the first slider 53 can be deformed, the metal plate 2 and the beam 1 can form a flexible connection through the first slider 53 and the first slide groove 42.

[0046] In order to improve the stability of the subsequent metal plate 2 and the photovoltaic module 3 when they are installed on the beam 1, or in other words, to improve the bearing capacity of the photovoltaic bracket for the photovoltaic module 3. Figure 5 As shown, the support assembly 5 may further include a bearing plate 55 ; the bearing plate 55 is connected to the bottom plate 51 and is used to support the metal plate 2 .

[0047] In order to enable the metal plate 2 to form a flexible connection with the support assembly 5 to reduce the vibration caused by external factors during daily use, in one embodiment of the present application, Figure 3 As shown, a first elastic member 44 may also be provided on the top of the substrate 41. Figure 5 As shown, a second elastic member 57 may also be provided on the top of the supporting plate 55 , and the tops of the first elastic member 44 and the second elastic member 57 are flush.

[0048] In this embodiment, the first elastic member 44 and the second elastic member 57 can be any one of a rubber pad, a rubber spring, and a gas spring. Since the elastic member has excellent buffering performance and deformation ability, it has good vibration reduction performance.

[0049] It should be noted that in the above-mentioned embodiment, the support assembly 5 and the crossbeam 1 can be welded or fixed. Figure 2 As shown, the support assembly 5 is fixed to the cross beam 1 by bolts. In the application scenario where the support assembly 5 is screwed and fixed to the cross beam 1, in order to facilitate the connection between the support assembly 5 and the cross beam 1, in the embodiment of the present application, the photovoltaic support may further include a clamping assembly 6. Figure 6 As shown, the clamping assembly 6 is arranged on the crossbeam 1. Figure 5 As shown, the support assembly 5 is provided with a second slide groove 56. Figure 7 As shown, the clamping assembly 6 includes a second sliding block, and the second sliding block and the second sliding groove 56 can form a sliding connection along the first direction.

[0050] In this embodiment, when installing the photovoltaic bracket, Figure 6As shown, at least two support assemblies 5 are placed on the top surface of the beam 1, and then the clamping assembly 6 is placed between the two support assemblies 5, so that the two ends of the clamping assembly 6 are respectively placed on the two support assemblies 5, and then the clamping assembly 6 and the beam 1 are tightened and fixed with bolts from bottom to top. The bolts give the clamping assembly 6 a downward force, and the two ends of the clamping assembly 6 act on the two support assemblies 5 at the same time, so that the two support assemblies 5 can be tightly pressed, thereby achieving the effect of fixing the two support assemblies 5 at the same time.

[0051] It can be seen that compared with Figure 2 In the embodiment of the photovoltaic bracket, in this embodiment, the clamping assembly 6 can be used to fix at least two support assemblies 5 at the same time, thereby improving the installation efficiency and saving the installation time. When the support assembly 5 is subsequently removed, it is only necessary to loosen the bolts and release the clamping assembly 6 from the support assembly 5, which greatly facilitates the disassembly of the support assembly 5 and improves the disassembly efficiency of the photovoltaic bracket.

[0052] It should be clear that in this embodiment, the support components 5 can be arranged in two rows, and a long strip-shaped clamping component 6 can be used to fix the two rows of support components 5 at the same time, so that the two rows of support components 5 can be fixed at one time, and subsequent disassembly is also very convenient.

[0053] In the embodiment of the present application, there is no limitation on the shape and structure of the second slider and the second slide groove 56. For example, the second slide groove 56 may be a T-shaped slide groove, and the second slider may include a horizontal plate 63 and a vertical plate 64 connected to each other, and the horizontal plate 63 and the vertical plate 64 are perpendicular to each other.

[0054] In the embodiment of the present application, there is no limitation on the shape and structure of the support assembly 5. Figure 7 As shown, the clamping assembly 6 also includes a pressing plate 61 and two inclined plates 62. The two inclined plates 62 are respectively arranged at both ends of the pressing plate 61, and one end of the inclined plate 62 away from the pressing plate 61 is higher than the pressing plate 61, and one end of the horizontal plate 63 away from the vertical plate 64 is connected to one end of the inclined plate 62.

[0055] It should be noted that if the clamping assembly 6 is Figure 6 As shown, if the photovoltaic components on either side of the photovoltaic bracket (not shown in the figure) are damaged, it is necessary to remove the photovoltaic components on both sides of the photovoltaic bracket. In order to facilitate the subsequent removal of the photovoltaic components on either side of the photovoltaic bracket according to needs without removing the photovoltaic components on the other side, in one embodiment of the present application, the clamping component 6 can be as shown in FIG. Fig.17 It should be noted that if the clamping assembly 6 is Fig.17 As shown, the clamping assembly 6 corresponds to the photovoltaic assembly one by one, that is, the clamping assembly 6 corresponding to the photovoltaic assembly to be removed can be removed based on demand, and the corresponding photovoltaic assembly can be removed.

[0056] In the embodiment of the present application, the metal plate 2 may be Figure 1 In order to improve the structural strength of the metal plate 2, in one embodiment of the present application, the metal plate 2 includes a metal corrugation 21 and at least one reinforcement member 22 disposed on the metal corrugation 21. Figure 8 As shown, the metal corrugated sheet 21 includes a first inclined portion 211, a corrugated bottom 212, and a second inclined portion 213 connected in sequence. The first end of each reinforcement member 22 is connected to the first inclined portion 211, and the second end of each reinforcement member 22 is connected to the second inclined portion 213. In this embodiment, the reinforcement member 22 is at least used to support the first inclined portion 211 and the second inclined portion 213, thereby preventing the first inclined portion 211 and the second inclined portion 213 from being deformed after being subjected to external force, that is, the reinforcement member 22 is at least used to limit the relative displacement of the first inclined portion 211 and the second inclined portion 213.

[0057] It should be clear that in the embodiment of the present application, a metal corrugation 21 is arranged on the metal plate 2, and a reinforcement member 22 is arranged in the metal corrugation 21, and the reinforcement member 22 can support the first inclined portion 211 and the second inclined portion 213 of the metal corrugation 21 to increase the overall structural strength of the metal corrugation 21. 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.

[0058] In the embodiment of the present application, there is no restriction on the shape and structure of the first inclined portion 211, the corrugated bottom 212 and the second inclined portion 213. For example, the first inclined portion 211, the corrugated bottom 212 and the second inclined portion 213 can be in the shape of an arc-shaped sheet. In order to facilitate the molding of the metal corrugated 21, in the embodiment of the present application, the first inclined portion 211, the corrugated bottom 212 and the second inclined portion 213 can be as follows: Figure 8 and Fig.11 It is easy to understand that the flat sheet-shaped first inclined portion 211, the corrugated bottom 212 and the second inclined portion 213 are easy to be formed by sheet rolling or stamping.

[0059] In the embodiment of the present application, the reinforcement 22 can be arranged inside the metal corrugated sheet 21 in any suitable manner. For example, if the first inclined portion 211 or the second inclined portion 213 is susceptible to external force in a certain direction during long-term use, the extension direction of the reinforcement 22 can be made parallel to the direction of the force, so that the reinforcement 22 can stably support the first inclined portion 211 or the second inclined portion 213. It should be noted that in order to ensure that the support force provided by the reinforcement 22 to the first inclined portion 211 and the second inclined portion 213 is uniform and equal, in one embodiment of the present application, it can be as follows Figure 8As shown, the extension direction of the reinforcement member 22 can be parallel to the width of the corrugated bottom 212 (i.e., as shown in FIG. Figure 8 The width in b) direction.

[0060] In the embodiment of the present application, there is no limitation on the shape and structure of the reinforcement member 22. It is only necessary that the reinforcement member 22 can provide support force for the first inclined portion 211 and the second inclined portion 213. For example, in the embodiment of the present application, the reinforcement member 22 can be a rod-shaped support rod 221 as shown in FIG9, or the reinforcement member 22 can include a rod-shaped support rod 221 as shown in FIG9. Fig.10 The support sheet 224 is shown in sheet form.

[0061] In the embodiment of the present application, the reinforcement member 22 can be connected to the first inclined portion 211 or the second inclined portion 213 in any suitable manner. Figure 8 As shown, the reinforcement member 22 is welded or integrally connected with the first inclined portion 211 and the second inclined portion 213. Alternatively, the reinforcement member 22 can be detachably connected with the first inclined portion 211 and the second inclined portion 213 through a connecting member (i.e., a connecting rod 222 or a connecting piece 225, etc., hereinafter) as described below.

[0062] It should be noted that in the embodiments of the present application, a connector may be provided only at the first end of the reinforcement 22, so that the first end of the reinforcement 22 can be connected to the first inclined portion 211 through the connector. A connector may also be provided only at the second end of the reinforcement 22, so that the second end of the reinforcement 22 can be connected to the second inclined portion 213 through the connector. A connector may also be provided at both the first end of the reinforcement 22 and the second end of the reinforcement 22. In order to avoid redundancy, in the subsequent embodiments or drawings, only the connection relationship between the first inclined portion 211 and the connector is introduced, or only the connection relationship between the second inclined portion 213 and the connector is introduced. It is easy to understand that in the embodiment in which only the connection relationship between the first inclined portion 211 and the connector is introduced, the connection relationship is also applicable to the second inclined portion 213 and the connector; of course, in the embodiment in which only the connection relationship between the second inclined portion 213 and the connector is introduced, the connection relationship is also applicable to the first inclined portion 211 and the connector, and no repeated description will be made later.

[0063] 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 211 or the second inclined portion 213) and the reinforcing member 22 form a detachable connection. For example, the connecting member can be as follows: Fig.10 The connecting piece 225 shown in the figure has at least one connecting hole, and when in use, the connecting piece 225 and the inclined portion can be connected by bolts or rivets. Alternatively, the connecting member can be as follows Fig. 9As shown, the connecting member includes a connecting ring 223 and a connecting rod 222. One end of the connecting rod 222 is connected to the connecting ring 223, and the other end of the connecting rod 222 is connected to the reinforcing member 22. When in use, the connecting ring 223 and the inclined portion can be connected by bolts or rivets.

[0064] It is easy to understand that if the reinforcement 22 can form a detachable connection with both the first inclined portion 211 and the second inclined portion 213, it is convenient to adjust the position of the reinforcement 22 according to the stress conditions of the metal corrugated sheet 21 during use, or to replace the reinforcement 22 with different mechanical strengths.

[0065] In the embodiment of the present application, there is no restriction on the connection method between the reinforcement member 22 and the connecting member. For example, the reinforcement member 22 and the connecting member can be fixedly connected. It is easy to understand that if the reinforcement member 22 and the connecting member are fixedly connected, in order to make the reinforcement member 22 compatible with the metal corrugated 21, the angle formed between the reinforcement member 22 and the connecting member can be compatible with the angle formed by the corrugated bottom 212 and the first inclined portion 211 or the second inclined portion 213.

[0066] In this embodiment, the matching of the reinforcement member 22 and the metal corrugated sheet 21 means that after the reinforcement member 22 and the metal corrugated sheet 21 are connected, there will be no internal stress between the reinforcement member 22 and the metal corrugated sheet 21 due to the connection. It is easy to understand that if there is internal stress between the reinforcement member 22 and the metal corrugated sheet 21 due to the connection, then during long-term use, the internal stress will cause the reinforcement member 22 or the metal corrugated sheet 21 to deform, thereby affecting the structural strength of the metal corrugated sheet 21 ... Figure 7 As shown, if the angle formed between the reinforcing member 22 and the connecting member is equal to the angle formed between the corrugated bottom 212 and the first inclined portion 211 or the second inclined portion 213, the internal stress formed after the reinforcing member 22 is connected to the metal corrugated 21 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 reinforcing member 22 and the connecting member can be adapted to the angle formed between the corrugated bottom 212 and the first inclined portion 211 or the second inclined portion 213, which means that the two angles are close to being equal.

[0067] In order to make the reinforcement member 22 applicable to the metal corrugated sheet 21 at any angle, in one embodiment of the present application, the reinforcement member 22 can be Fig. 9 and Fig.10As shown, the reinforcing member 22 can be hinged with the connecting member. It is easy to understand that if the reinforcing member 22 is hinged with the connecting member, the angle between the reinforcing member 22 and the connecting member can be adjusted according to the angle between the inclined portion of the metal corrugated sheet 21 and the corrugated bottom 212, so that after the reinforcing member 22 is connected to the metal corrugated sheet 21 at any angle, the internal stress formed between the reinforcing member 22 and the metal corrugated sheet 21 due to the connection is small.

[0068] It should be clear that since the photovoltaic module 3 has an inclined angle and is outdoors, during long-term use, wind and rain may cause the photovoltaic bracket to vibrate, thereby loosening the fastening bolts 23 of the fastening reinforcement 22, which in turn reduces the structural strength of the metal plate 2 in the photovoltaic bracket. If the structural strength of the metal plate 2 is reduced, the photovoltaic module 3 disposed on the photovoltaic bracket is at risk of falling. If the photovoltaic module 3 falls, the photovoltaic module 3 may be damaged at best, or even cause a safety accident at worst.

[0069] In order to prevent the metal plate 2 from losing structural strength due to loosening of the fastening bolts 23, in one embodiment of the present application, Fig.11 As shown, the reinforcement 22 is threadedly connected to the metal corrugated sheet 21 via the fastening bolts 23. Fig.12 As shown, the reinforcement member 22 is further provided with a first limiting strip 226 and a second limiting strip 227. The first limiting strip 226 and the second limiting strip 227 are elastic or plastic, and the first limiting strip 226 has a first plane, and the second limiting strip 227 has a second plane opposite to the first plane. The fastening bolt 23 has a third plane and a fourth plane. When in use, the third plane is opposite to the first plane, and the fourth plane is opposite to the second plane, which is used to limit the rotation of the fastening bolt 23.

[0070] It should be noted that, under the limiting effect between the first plane, the second plane, the third plane and the fourth plane, the fastening bolt 23 cannot rotate during use. If the fastening bolt 23 cannot rotate, then during long-term use, the fastening bolt 23 must not be loosened. In other words, the embodiment of the present application can limit the rotation of the fastening bolt 23 through the first plane on the first limit strip 226 and the second plane on the second limit strip 227, in conjunction with the third plane and the fourth plane on the fastening bolt 23, that is, it can prevent the fastening bolt 23 from loosening. During long-term use, if the fastening bolt 23 is difficult to loosen, the structural strength of the photovoltaic bracket will decrease due to the loosening of the fastening bolt, and the phenomenon of photovoltaic modules falling and being damaged or causing safety accidents will be difficult to occur.

[0071] It should be noted that, in the present embodiment, the first limit strip 226 and the second limit strip 227 are elastic or plastic, that is, the first limit strip 226 and the second limit strip 227 can undergo elastic deformation or plastic deformation, that is, in the subsequent use process, the part of the fastening bolt 23 having the third plane and the fourth plane (for example, it can be the nut or threaded rod of the fastening bolt 23) can be placed between the first limit strip 226 and the second limit strip 227 without damaging the first limit strip 226 and the second limit strip 227, so that the first limit strip 226 and the second limit strip 227 can limit the fastening bolt 23.

[0072] In the embodiment of the present application, there is no restriction on the shape and structure of the first limiting strip 226 and the second limiting strip 227. For example, the first limiting strip 226 and the second limiting strip 227 can be in the shape of a rectangular strip, or in the shape of a rectangular strip. Fig.12 It should be noted that, compared with the rectangular strip, Fig.12 The bottom of the long strip-shaped first limit strip 226 and the second limit strip 227 are arc-shaped, so it is difficult for stress concentration to form at the bottom of the first limit strip 226 and the second limit strip 227, that is, when the part of the fastening bolt 23 with the third plane and the fourth plane is screwed into the first limit strip 226 and the second limit strip 227, the first limit strip 226 and the second limit strip 227 will not crack and separate from the reinforcement 22 due to stress concentration.

[0073] In an embodiment of the present application, the first plane, the second plane, the third plane and the fourth plane can be matched in any reasonable manner to limit the rotation of the fastening bolt 23. For example, in an embodiment of the present application, the first plane, the second plane, the third plane and the fourth plane can be matched in the following manner: Fig.14 In order to stably limit the position of the fastening bolt 23, as shown in FIG. Fig.13 As shown, the first plane and the second plane may be parallel, that is, the third plane and the fourth plane are parallel.

[0074] It should be noted that in the application scenario where the first plane and the second plane are parallel, in order to ensure that the fastening bolt 23 is easily installed between the first limiting strip 226 and the second limiting strip 227, the distance between the first plane and the second plane (i.e. Fig.13 The distance S1 shown in FIG. 1 may be greater than or equal to the distance between the third plane and the fourth plane (ie, Fig.13The distance S2 shown in the figure). It is easy to understand that if the distance between the first plane and the second plane is greater than or equal to the distance between the third plane and the fourth plane, then after installation, the third plane on the fastening bolt 23 is in contact with or has a gap with the first plane on the first limiting strip 226, and the fourth plane on the fastening bolt 23 is also in contact with or has a gap with the second plane on the second limiting strip 227. Compared with the application scenario in which the fastening bolt 23 conflicts with the first limiting strip 226 or the second limiting strip 227 after installation, the application scenario in which the fastening bolt 23 is in contact with or has a gap with the first limiting strip 226 or the second limiting strip 227 after installation is more convenient for installing the fastening bolt 23.

[0075] It should be noted that in the application scenario where the first plane and the second plane are parallel, in order to ensure that the combination of the first plane, the second plane, the third plane and the fourth plane can stably limit the fastening bolt 23. Fig.13 The distance S1 shown in FIG. 1 must be smaller than the maximum outer diameter of the fastening bolt 23 around the third plane and the fourth plane (i.e., Fig.13 It is easy to understand that if the distance between the first plane and the second plane is smaller than the maximum outer diameter of the fastening bolt 23 around the third plane and the fourth plane, the fastening bolt 23 is difficult to rotate under the restriction of the first plane and the second plane.

[0076] In order to facilitate the quick connection of the metal plate 2 with the metal corrugation 21 and the crossbeam 1. In one embodiment of the present application, the photovoltaic support further includes a connecting plate 7, a contoured support plate 8 and at least one fixing plate 71. Fig.15 and Fig.16 As shown, the connecting plate 7 is connected to the supporting assembly 5, and the connecting plate 7 is perpendicular to the top surface of the beam 1, and the connecting plate 7 is parallel to the side of the beam 1. The contoured support plate 8 is vertically fixed to the side of the connecting plate 7 facing the metal plate 2 and close to the bottom of the connecting plate 7. The fixing plate 71 is fixed to the top of the connecting plate 7 and is perpendicular to the connecting plate 7. The fixing plate 71 and the contoured support plate 8 are located on the same side of the connecting plate 7.

[0077] In this implementation, if Fig.15 As shown, the contoured support plate 8 is vertically fixed to the side of the connecting plate 7 and close to its bottom position, and two fixing plates 71 are respectively fixedly installed on both sides of the top of the connecting plate 7, and the fixing plates 71 are parallel to the contoured support plate 8, and the upper surfaces of the two fixing plates 71 are flush. Fig.16 As shown, the shape of the profiled support plate 8 is similar to the shape of the metal corrugated sheet 21. The connecting plate 7, the profiled support plate 8 and the fixing plate 71 form the above-mentioned bearing area. Fig.16As shown, when the metal plate 2 is placed in the load-bearing area, the contoured support plate 8 holds up the bottom surface of the metal plate 2 , while the two fixing plates 71 hold up the lower surface of the top of the metal plate 2 .

[0078] For example, the high points of the metal plate 2 are named as peaks, and the low points are named as low peaks. Fig.16 It can be clearly seen that the lower peak of the metal plate 2 is placed on the contoured support plate 8, and the two adjacent peaks of the metal plate 2 are respectively placed on the two fixing plates 71. In this way, the metal plate 2 can fall into the load-bearing area stably.

[0079] In order to further improve the bearing capacity of the contoured support plate 8 and improve the stability of the metal plate 2 falling into the contoured support plate 8. Fig.16 As shown, the angle formed by the left and right sides of the profiling support plate 8 is an obtuse angle. It should be noted that the angle formed by the left and right sides of the profiling support plate 8 can be slightly smaller than the obtuse angle of the bottom of the metal corrugation 21. In this way, when the bottom of the metal corrugation 21 is pressed into the profiling support plate 8 and slowly moves downward, the profiling support plate 8 is gradually squeezed and opened outward, and then an inward clamping force can be applied to the metal corrugation 21 to clamp the metal corrugation 21.

[0080] It should be clear that in the embodiment of the photovoltaic bracket proposed in the present application, since the auxiliary frame and the supporting connector can slide relative to each other, after the restriction of the auxiliary frame and the supporting connector by the limiting mechanism is released, the relative position of the auxiliary frame and the supporting connector can be changed again, and finally the auxiliary frame and the supporting connector can be re-restricted by the limiting mechanism, so that the installation position of the photovoltaic component can be flexibly changed, and the steps of changing the position are simple and easy to operate. By setting the clamping assembly, at least two supporting assemblies can be fixed at the same time, thereby improving the installation efficiency of the photovoltaic bracket and saving installation time. When the support assembly is subsequently removed, it is only necessary to loosen the nut and release the clamping assembly from the support assembly, which greatly facilitates the disassembly of the support assembly and improves the disassembly efficiency of the photovoltaic bracket.

[0081] After introducing a photovoltaic bracket proposed in an embodiment of the present application, a photovoltaic system proposed in the present application is introduced below. The photovoltaic system includes a photovoltaic component 3 and a photovoltaic bracket proposed in any one of the above embodiments; the photovoltaic component 3 is arranged on the photovoltaic bracket.

[0082] It should be clear that in the embodiment of the photovoltaic system proposed in the present application, since the auxiliary frame and the supporting connector in the photovoltaic bracket can slide relative to each other, after the restriction of the auxiliary frame and the supporting connector by the limiting mechanism is released, the relative position of the auxiliary frame and the supporting connector can be changed again, and finally the auxiliary frame and the supporting connector can be re-restricted by the limiting mechanism, so that the installation position of the photovoltaic component can be flexibly changed, and the steps of changing the position are simple and easy to operate. By setting the clamping assembly, at least two supporting assemblies can be fixed at the same time, thereby improving the installation efficiency of the photovoltaic bracket and saving installation time. When the supporting assembly is subsequently removed, it is only necessary to loosen the nut and release the clamping assembly from the supporting assembly, which greatly facilitates the disassembly of the supporting assembly and improves the disassembly efficiency of the photovoltaic bracket.
