Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic technology, and more specifically, to a support assembly and a photovoltaic system. Background Technology

[0002] In photovoltaic systems, it is usually necessary to install support structures such as roofs. Support structures typically include multiple supports that work together to support the supporting structure, which in turn supports the photovoltaic panels.

[0011] Optionally, the fixing base includes a plate and a seat, the seat being located at the upper end of the plate and integrally connected to the plate; the fastener is connected to the fixing base on the plate; the sealing structure is located above the plate and connected to the plate; the sealing structure is thermally fused to the waterproof membrane layer to form a single unit.

[0012] Optionally, the fixing seat is provided with a first through hole;

[0013] The fastener passes through the first through hole and the waterproof membrane layer in sequence and is connected to the support layer. The sealing structure is located above the fastener and is integrally connected to the plate body.

[0014] Alternatively, the fastener passes sequentially through the sealing structure, the first through-hole, and the waterproof membrane layer and is connected to the support layer, such that a portion of the sealing structure is sandwiched between the fastener and the plate.

[0015] Optionally, the base includes a first base and a second base, wherein the first base is integrally connected to the plate, and the second base is detachably connected to the first base.

[0016] Optionally, the through-type support is detachably fixedly connected to the support structure;

[0017] Alternatively, the penetrating support and the supporting structure are movably connected in a set direction, and the set direction is set at a preset angle with the supporting surface formed by the supporting layer.

[0018] Optionally, the bracket assembly further includes a first connector, the through-type support is provided with a first connection hole, the support structure is provided with a second connection hole, and the first connector passes through the first connection hole and the second connection hole;

[0019] When the penetrating support and the supporting structure are relatively movable in the set direction, the axial direction of the first connector is consistent with the set direction, and at least one of the first connecting hole and the second connecting hole is movably disposed relative to the first connector in the axial direction of the first connector; or, the axial direction of the first connector is set at the preset angle with the set direction, one of the first connecting hole and the second connecting hole is a round hole and the other is an oblong hole, and the extension direction of the oblong hole is consistent with the set direction.

[0023] In the bracket assembly and photovoltaic system disclosed herein, the bracket assembly includes penetrating and non-penetrating supports. The penetrating supports pass through the waterproof membrane layer of the supporting surface structure and connect to the supporting layer of the supporting surface structure. The non-penetrating supports connect to the waterproof membrane layer. Both penetrating and non-penetrating supports are used to connect to the supporting structure. The support structure is supported on the supporting surface structure through the combined use of the penetrating and non-penetrating supports. The supporting structure can be reused for the installation of, for example, photovoltaic modules. A greater number of supports can be arranged between the supporting structure and the supporting surface structure, thereby reducing the required number of penetrating supports and reducing the structural requirements for connecting the supports to the supporting layer. This reduces the overall layout cost of the bracket assembly while still meeting the support and fixation requirements of the supporting structure, and also reduces the possibility of leakage from the waterproof membrane layer. Furthermore, since the structural requirements for connecting the supports to the supporting layer are reduced, the impact on the supporting layer is minimized, ensuring the structural reliability of the supporting layer.

[0049] The first aspect of the embodiments of this disclosure provides a support assembly including a plurality of supports 1, through which a support structure 62 is supported on a support surface structure 5.

[0050] like Figure 1 and Figure 4 As shown, Figure 1 This is a schematic diagram of the support structure 62 supported by the bracket assembly in the first embodiment of this disclosure; Figure 4 This is a schematic diagram of the support assembly when the waterproof membrane layer 51 of the support surface structure 5 holds the non-penetrating support 11 under the wind suction condition in the first embodiment of this disclosure.

[0051] The plurality of supports 1 include a non-penetrating support 11 and a penetrating support 12. The penetrating support 12 is used to pass through the waterproof membrane layer 51 of the support surface structure 5 and connect to the support layer 53 of the support surface structure 5. The non-penetrating support 11 is used to connect to the waterproof membrane layer 51. The non-penetrating support 11 and the penetrating support 12 are respectively used to connect to the support structure 62.

[0052] Specifically, the main difference between the penetrating support 12 and the non-penetrating support 11 lies in whether it penetrates the waterproof membrane layer 51 and connects to the support layer 53. The penetrating support 12 partially penetrates the waterproof membrane layer 51 and connects to the support layer 53, thus fixing the penetrating support 12 relative to the support layer 53. In some scenarios, the penetrating support 12 can press the waterproof membrane layer 51 against the support layer 53. The non-penetrating support 11 only connects to the waterproof membrane layer 51 and is not directly connected to the support layer 53.

[0053] It should be noted that this specification will use the use of bracket components in photovoltaic systems as an example to illustrate the content of this disclosure, and references should be made accordingly. Figure 16 As shown, in this configuration, multiple supports 1 are connected to the support structure 62, and through the support structure 62, to the photovoltaic panel module 61. The support structure 62 may include purlin components. The support surface structure 5 may be a roof structure. For example, the support surface structure 5 may include, from bottom to top, a support layer 53, an insulation layer 52, and a waterproof membrane layer 51. The support layer 53 may include a steel plate layer. However, it should be understood that, without departing from the design concept of this disclosure, it may also be used in other applications. For example, the support structure 62 may be used to support other structures.

[0054] Thus, the support assembly in this disclosure includes penetrating supports 12 and non-penetrating supports 11. The penetrating supports 12 are used to pass through the waterproof membrane layer 51 of the support surface structure 5 and connect to the support layer 53 of the support surface structure 5. The non-penetrating supports 11 are used to connect to the waterproof membrane layer 51. The non-penetrating supports 11 and the penetrating supports 12 are respectively used to connect to the support structure 62. The support structure 62 is supported on the support surface structure 5 by the non-penetrating supports 11 and the penetrating supports 12. The support structure 62 can be reused for the installation of, for example, photovoltaic modules. More supports 1 can be arranged between the support structure 62 and the support surface structure 5, which can reduce the number of penetrating supports 12 and reduce the structural requirements for arranging the support layer 53 to connect to the supports 1. Thus, while taking into account the support and fixation requirements of the support structure 62, the overall arrangement cost of the support assembly can be reduced, and the possibility of leakage of the waterproof membrane layer 51 can be reduced. In addition, since the structural requirements for arranging the support layer 53 and connecting it to the support 1 can be reduced, the impact on the support layer 53 can be reduced to a certain extent, ensuring the structural reliability of the support layer 53.

[0055] like Figure 4As shown, optionally, the portion of the waterproof membrane layer 51 connected to the non-penetrating support 11 is configured to be movable relative to the support layer 53.

[0056] Specifically, the waterproof membrane layer 51 is laid on the insulation layer 52, and it has a fixed connection portion 511, a movable connection portion 512, and an intermediate connection portion 513 between the fixed connection portion 511 and the movable connection portion 512. The fixed connection portion 511 is fixedly disposed relative to the support layer 53, and the movable connection portion 512 is movable relative to the support layer 53. The structural form of the connection between the fixed connection portion 511 of the waterproof membrane layer 51 and the support layer 53 is not limited, nor is the structural form of the connection between the movable connection portion 512 and the non-penetrating support 11. For example, a portion of the fixed connection portion 511 of the waterproof membrane layer 51 is connected to the penetrating support 12, thereby fixing this portion of the fixed connection portion 511. A portion of the movable connection portion 512 of the waterproof membrane layer 51 is connected to the non-penetrating support 11.

[0057] Specifically, the movable connecting part 512 can move relative to the support layer 53 in a set direction, and the set direction is set at a preset angle with the support surface 531 formed by the support layer 53. The preset angle is a right angle. Figure 4 In the diagram, the direction is set to be consistent with the Z-axis direction. When the non-penetrating support 11 moves, causing the movable connecting part 512 to move and making the intermediate connecting part 513 between the fixed connecting part 511 and the movable connecting part 512 in a tensile and taut state, the waterproof membrane layer 51 can restrict the movable connecting part 512 from continuing to move away from the support layer 53, thereby providing tension to the non-penetrating support 11. This tension can be used to prevent the non-penetrating support 11 from flying out, which is beneficial to improving the wind suction resistance of the support structure 62.

[0058] For example, such as Figure 1 As shown, under natural working conditions (which can be understood as windless working conditions), the support structure 62 can be supported by the non-penetrating support 11 and the penetrating support 12 together, ensuring the reliability of the support structure 62. For example, the support structure 62 can obtain relatively uniform support within its coverage area.

[0059] like Figure 4 and Figure 5 As shown, under wind suction conditions, the penetrating support 12 fixes the supporting structure 62. At the same time, the supporting structure 62 has a tendency to move upward in a set direction, and the non-penetrating support 11 has a tendency to move upward relative to the supporting layer 53. The waterproof membrane layer 51 is stretched and applies tension to the non-penetrating support 11, so that the non-penetrating support 11 can apply tension to a certain extent, avoiding excessive force on the penetrating support 12 and preventing the supporting structure 62 from flying out due to wind suction.

[0060] Thus, under natural working conditions (or windless working conditions), the non-penetrating support 11 and the penetrating support 12 can jointly support the support structure 62, allowing the support structure 62 to receive support at multiple locations within its coverage area. At this time, the waterproof membrane layer 51 can be in a relatively natural state; for example, the waterproof membrane layer 51 can be attached to the insulation layer 52 without affecting the walking and working of maintenance personnel on the support layer 53. Under wind suction conditions, when the support structure 62 and its upper structure, such as photovoltaic modules, are subjected to wind force greater than gravity, the penetrating support 12 can restrict the upward movement of the support structure 62 at its connection position. The non-penetrating support 11 transmits force to the waterproof membrane layer 51 it is connected to. When the middle connection part 513 of the waterproof membrane layer 51 is tightened, the tension transmitted through the waterproof membrane layer 51 can also restrict the upward movement of the support structure 62 at the connection position of the non-penetrating support 11, allowing the support structure 62 to receive tension at multiple locations within its coverage area. Therefore, the bracket assembly of this embodiment can not only realize the installation of the support structure 62, such as the photovoltaic panel assembly 61, on the support layer 53, but also prevent the photovoltaic panel assembly 61 from flying out under conditions such as wind suction. Under both natural and wind suction conditions, the bracket assembly can provide position-holding forces for the support structure 62 at multiple locations within the coverage area of ​​the support structure 62, ensuring the installation reliability of the support structure 62 and reducing the risk of damage to the support structure 62 and its upper structure due to excessive local stress under wind suction or snow pressure conditions (such as snow accumulation on the photovoltaic panel).

[0061] It should be understood that in some scenarios, when the intermediate connection 513 of the waterproof membrane layer 51 is just at the critical state of being stretched and not stretched, the non-penetrating support 11 can be suspended. In this way, in the initial stage of the wind suction condition, the gravity of the support structure 62 and the initial stiffness formed by its connection with the penetrating support 12 can be used to resist its wind suction force. When the support structure 62, such as the purlin assembly, has a certain initial deformation, the intermediate connection 513 is stretched, and the non-penetrating support 11 can apply force to prevent the support structure 62 from deforming too much and breaking.

[0062] In the above embodiments, optionally, fixed connecting portions 511 are distributed in multiple directions around the movable connecting portion 512 in a plane parallel to the support surface 531.

[0063] Thus, under wind suction conditions, when the non-penetrating support 11 and its connected movable connection 512 move upward in a set direction, the movable connection 512 can be subjected to the force transmitted by the fixed connection 511 in multiple directions through the intermediate connection 513, reducing the possibility of continued deformation of the support structure 62 at the connection of the non-penetrating support 11 and reducing the risk of damage to the support structure 62.

[0064] Optionally, in the inner side of at least one movable connection 512, which is parallel to the support surface 531, at least two fixed connection portions 511 are located on a circumference with the movable connection 512 as the center, and the at least two fixed connection portions 511 are evenly distributed on the circumference.

[0065] For example, for any movable connecting part 512, at least two fixed connecting parts 511 are correspondingly provided, wherein the at least two fixed connecting parts 511 can be approximately located on the same circumference, and the center of the circumference is provided corresponding to the movable connecting part 512. The outside of the circumference can also have other fixed connecting parts 511, but these other fixed connecting parts 511 are not used to serve as a tension fixing end for the movable connecting part 512, and will not be described in detail later.

[0066] like Figure 4 As shown, for example, two fixed connection portions 511 are distributed on the circumference, and the line connecting the two fixed connection portions 511 passes through the center of the circle. In this case, the fixed connection portion 511 can be simply understood as the junction where the waterproof membrane layer 51 and the support layer 53 adhere and separate under wind suction conditions.

[0067] Thus, under wind suction conditions, when the non-penetrating support 11 and its connected movable connection 512 move upward in the set direction, the fixed connection 511 evenly distributed on the circumference applies force through the corresponding intermediate connection 513, so that the resultant force on the movable connection 512 is approximately downward in the set direction, and the tension on the support structure 62 at the non-penetrating support 11 is mainly downward in the set direction. The movement direction of the support structure 62 at the non-penetrating support 11 is highly controllable, and the stress stability is high.

[0068] The method of connecting the non-penetrating support 11 to the waterproof membrane layer 51 is not limited. For example, in some scenarios, the two can be connected as one unit by adhesive.

[0069] like Figure 8 As shown in the above embodiment, optionally, the non-penetrating support 11 includes a support body 111 and a waterproof membrane structure 113. The upper end of the support body 111 is used to connect with the support structure 62. The waterproof membrane structure 113 is connected to the support body 111, and the waterproof membrane structure 113 is integrated with the waterproof membrane layer 51.

[0070] For example, waterproof membrane structures 113 are distributed on one or more sides of the base body 111. The waterproof membrane structures 113 are connected to the base body 111 and are fixed to each other at the connection point. The two can be connected as a whole by means of adhesive bonding, injection molding, etc., or they can be detached. The lower end of the waterproof membrane structure 113 is connected to the movable connection part 512 of the waterproof membrane layer 51 as a whole, for example, by means of adhesive bonding or hot melt bonding.

[0071] In this case, it is convenient to connect the non-penetrating support 11 to the waterproof membrane layer 51, and the contact area between the waterproof membrane structure 113 and the waterproof membrane layer 51 can be set to a relatively large size as needed.

[0072] Furthermore, the non-penetrating support 11 also includes a pressure plate 112, which is detachably connected to the support body 111, and a portion of the waterproof membrane structure 113 is sandwiched between the pressure plate 112 and the support body 111.

[0073] In other words, the waterproof membrane structure 113 is pressed tightly onto the seat body 111 by the corresponding pressure plate 112, which facilitates connection operations and maintenance.

[0074] Furthermore, the waterproof membrane structure 113 and the waterproof membrane layer 51 are thermally fused together to form a single unit. This thermal fusion connection can be achieved using hot air welding, which will not be described in detail later.

[0075] like Figure 3 As shown in the above embodiment, optionally, the penetrating support 12 includes a fixing seat 121 and a fastener 122. The fastener 122 passes through the waterproof membrane layer 51. The fastener 122 is connected to the fixing seat 121 and the support layer 53 respectively. The fixing seat 121 is sealed to the waterproof membrane layer 51 through a sealing structure 123.

[0076] The method by which the fixing seat 121 is sealed to the waterproof membrane layer 51 through the sealing structure 123 is not a limitation, as long as it prevents leakage from the fixing seat 121 to the bottom of the waterproof membrane layer 51.

[0077] In this way, the fixed base 121 is connected and fixed to the support structure 62 by the fastener 122 and waterproofed by the sealing structure 123. This can meet the requirement of reliable fixation of the penetrating support 12 on the support layer 53, and also reduce the possibility of poor water leakage of the waterproof membrane layer 51 due to the arrangement of the fastener 122, thus achieving better installation reliability and waterproof reliability.

[0078] In some scenarios, the sealing structure 123 can be in the form of a sealing ring to achieve the sealing requirement. This is not shown in the attached drawings and will not be described in detail in this manual.

[0079] like Figure 6 and Figure 7As shown, optionally, the sealing structure 123 is made of a waterproof membrane material and is located within the support surface 531 formed by the support layer 53. The projection of the sealing structure 123 covers the projection of the outer periphery of the fixing seat 121 on the support surface 531. The sealing structure 123 is connected to the fixing seat 121, and the sealing structure 123 is integrated with the waterproof membrane layer 51. The connection area formed by the connection of the sealing structure 123 and the waterproof membrane layer 51 surrounds the outer periphery of the fixing seat 121.

[0080] Specifically, taking the projection outline of the outer periphery of the fixing base 121 onto the support surface 531 as the boundary, the sealing structure 123 has a portion corresponding to the area enclosed by the projection outline, and also has a portion corresponding to the area enclosed by the projection outline. The portion located inside is connected to the fixing base 121, and the connection is sealed. The portion located outside is connected to the waterproof membrane layer 51 as a whole, so that the connection area formed by the connection between the sealing structure 123 and the waterproof membrane layer 51 surrounds the outer periphery of the fixing base 121.

[0081] The sealing structure 123 and the waterproof membrane layer 51 can be made of the same waterproof membrane material, which makes it easy for the two to be connected into one by heat fusion.

[0082] Thus, the sealing structure 123 is made of waterproof membrane material, which facilitates the connection between the sealing structure 123 and the waterproof membrane layer 51. The structural design of the sealing structure 123 allows it to have a relatively complete connection area with the waterproof membrane layer 51, ensuring the waterproof performance of the outer periphery of the fixing seat 121.

[0083] like Figure 6 and Figure 7 As shown, the fixing base 121 includes a plate 1211 and a seat 1212. The seat 1212 is located at the upper end of the plate 1211 and is integrally connected to the plate 1211. The fastener 122 is connected to the fixing base 121 on the plate 1211. The sealing structure 123 is located above the plate 1211 and is connected to the plate 1211. The sealing structure 123 is thermally fused to the waterproof membrane layer 51.

[0084] In this case, even if the sealing structure 123 covers the upper surface of the plate 1211 but not the entire seat 1212, the sealing structure 123 can still ensure the waterproof performance at the fixing seat 121, which facilitates the arrangement of the sealing structure 123.

[0085] In the above embodiments, it should be understood that in some scenarios, the fixing base 121 is provided with a first through hole 1213 (the first through hole 1213 is in...). Figure 7 It is shown that it is not in Figure 3(As shown), the fastener 122 passes through the first through hole 1213 and the waterproof membrane layer 51 and is connected to the support layer 53. At this time, the sealing structure 123 also needs to achieve a seal at the first through hole 1213, which will be used as an example for explanation later. Of course, it should be understood that the fastener 122 can also be integrally connected with the fixing seat 121.

[0086] like Figure 7 and Figure 19 As shown, exemplarily, the fastener 122 passes through the first through hole 1213 and the waterproof membrane layer 51 in sequence and is connected to the support layer 53. The sealing structure 123 is located above the fastener 122 and is integrally connected to the plate body 1211.

[0087] Specifically, the fastener 122 can be a first screw or anchor, etc. The sealing structure 123 at least covers the location of the fastener 122 and the outer periphery of the fixing seat 121. Thus, the sealing structure 123 can be connected to the fixing seat 121 on the outer periphery of the fastener 122, i.e., the outer periphery of the first through hole 1213, by means of hot air welding or the like, forming a sealing structure 123 at the installation position of the fastener 122 above the fastener 122. The sealing structure 123 prevents external rainwater from entering the first through hole 1213 by connecting to the fixing seat 121 on the outer periphery of the first through hole 1213. Furthermore, the sealing structure 123 is also connected to the fixing seat 121 and the waterproof membrane layer 51 on the outer periphery of the fixing seat 121 by means of hot air welding or the like, forming a sealing structure 123 at the junction of the outer periphery of the fixing seat 121 and the waterproof membrane layer 51, which can prevent rainwater from entering below the waterproof membrane layer 51 from the outer periphery of the fixing seat 121, ensuring the waterproof performance of the support layer 53.

[0088] Unlike the design where the sealing structure 123 is located above the fastener 122, in some scenarios, the fastener 122 passes sequentially through the sealing structure 123, the first through-hole 1213, and the waterproof membrane layer 51 and connects to the support layer 53, so that a portion of the sealing structure 123 is sandwiched between the fastener 122 and the plate 1211. This design is not shown in the figure.

[0089] At this time, the fastener 122 can connect the fixed base 121 to the support layer 53 and the sealing structure 123 to the fixed base 121. The part where the sealing structure 123 is connected to the fastener 122 can achieve a similar effect to a sealing ring, preventing rainwater from leaking from the first through hole 1213.

[0090] It should be understood that in some scenarios, when a sealing structure 123 is provided and the sealing structure 123 is made of waterproof membrane material, the lower surface of the plate 1211 can also be connected to the waterproof membrane layer 51 by adhesive or other waterproofing methods to improve its waterproof performance.

[0091] like Figure 7 and Figure 19 As shown, the seat 1212 further includes a first seat 12121 and a second seat 12122. The first seat 12121 is integrally connected to the plate 1211, and the second seat 12122 is detachably connected to the first seat 12121.

[0092] For example, the lower end of the second seat 12122 is provided with a second groove structure 12125, the lower end of the first seat 12121 is integrally connected to the plate 1211, the upper end of the first seat 12121 is accommodated in the second groove structure 12125, and the first seat 12121 and the second seat 12122 are detachably connected by horizontally arranged bolts. In this case, it is convenient for the processing and replacement of the second seat 12122.

[0093] It should be understood that in some scenarios, in addition to covering the upper surface of the plate 1211, the sealing structure 123 may also have a portion arranged on the surface of the first seat 12121. For example, the sealing structure 123 is located between the first seat 12121 and the second seat 12122, and is thermally fused with the first seat 12121. In this way, the sealing structure 123 and the fixed seat 121 can achieve a larger contact area, thereby improving the reliability of its connection with the fixed seat 121.

[0094] In the above embodiments, the penetrating support 12 is optionally detachably fixedly connected to the support structure 62.

[0095] like Figure 6 As shown, exemplarily, the upper end of the through-type support 12 has a first groove structure 12123. A portion of the support structure 62 is accommodated in the first groove structure 12123, for example, the longitudinal purlin 622 of the support structure 62 is accommodated in the first groove structure 12123. The first groove structure 12123 has a first connecting hole 12124, and the longitudinal purlin 622 has a second connecting hole 623. The first connecting hole 12124 and the second connecting hole 623 extend axially along the Y-axis direction. The first connecting member 4 passes through the first connecting hole 12124 and the second connecting hole 623 along the Y-axis direction and connects the first groove structure 12123 and the longitudinal purlin 622 together. The first connecting hole 12124 and the second connecting hole 623 can both be round holes, and the displacement of the two in a set direction is restricted by the connecting action of the first connecting member 4.

[0096] It should be understood that, unlike the first embodiment described above, the technical solution in which the first connector 4 passes through the first connecting hole 12124 and the second connecting hole 623 along the Y-axis direction and connects the first groove structure 12123 and the longitudinal purlin 622 together is different. Figure 9 , 10 As shown, Figure 9 This is a schematic diagram of the support assembly when the waterproof membrane layer 51 of the support surface structure 5 holds the non-penetrating support 11 under the wind suction condition in the second embodiment of this disclosure. Figure 10 for Figure 9 For a detailed enlarged view of point E, please refer to [link / reference]. Figure 10 The first connecting hole 12124 and the second connecting hole 623 can be extended along the Z-axis direction. The first connecting piece 4 passes through the first connecting hole 12124 and the second connecting hole 623 and connects the first groove structure 12123 and the longitudinal purlin 622 together. It can also fix the relative position of the through-type support 12 and the support structure 62.

[0097] like Figure 12 and 13 As shown, please refer to the following for details. Figure 13 Unlike the above embodiment where the penetrating support 12 and the support structure 62 are detachably and fixedly connected, optionally, the penetrating support 12 and the support structure 62 are connected in a relatively movable direction, and the set direction is set at a preset angle with the support surface 531 formed by the support layer 53. Ideally, the preset angle is a right angle.

[0098] At this time, the axial direction of the first connector 4 is consistent with the set direction, and at least one of the first connecting hole 12124 and the second connecting hole 623 is movably disposed relative to the first connector 4 along the axial direction of the first connector 4; or, the axial direction of the first connector 4 is set at the preset angle to the set direction, one of the first connecting hole 12124 and the second connecting hole 623 is a round hole, and the other is an oblong hole, the extension direction of the oblong hole is consistent with the set direction. Further explanation will follow with specific embodiments.

[0099] In this embodiment, under the condition of wind suction, when the wind suction force is greater than the weight of the support structure 62, the support structure 62 can move as a whole along the set direction to the end away from the support layer 53, that is, the upper end, until the resultant force of the tension provided by the entire bracket assembly and the weight of the support structure 62 cancels out the wind suction force.

[0100] In this embodiment, the travel distance of the penetrating support 12 and the supporting structure 62 relative to each other in a set direction (this travel distance is referenced) Figure 13 The corresponding L2) can be designed as a non-penetrating support 11 with a travel distance in a set direction (this travel distance is referenced). Figure 12Consistent with L1, when the support structure 62 is located at the lower limit position near the lower end in the set direction, the non-penetrating support 11 and the penetrating support 12 support the support structure 62 respectively, so that the support structure 62 can maintain a good stress condition and reduce the possibility of uneven stress and local bending. Under the wind suction condition, when the support structure 62 is located at the upper limit position near the upper end in the set direction, the non-penetrating support 11 and the penetrating support 12 provide tension to the support structure 62 respectively, so that the support structure 62 can maintain a good stress condition and reduce the possibility of uneven stress and local bending.

[0101] In a further alternative embodiment where the penetrating support 12 and the support structure 62 are relatively movable in a predetermined direction, the bracket further includes at least one of a first buffer structure 2 and a second buffer structure 3; the first buffer structure 2 is connected to the penetrating support 12 and is located on the movement path of the support structure 62 moving towards one end in the predetermined direction; the second buffer structure 3 is connected to the penetrating support 12 and is located on the movement path of the support structure 62 moving towards the other end in the predetermined direction.

[0102] For example, the first buffer structure 2 and the second buffer structure 3 are in Figure 13 The diagram schematically shows a first buffer structure 2 disposed between the penetrating support 12 and the supporting structure 62 to buffer the upward movement of the penetrating support 12 in a predetermined direction; a second buffer structure 3 disposed between the penetrating support 12 and the supporting structure 62 to buffer the downward movement of the penetrating support 12 in a predetermined direction. The penetrating support 12 may be provided with structures for mounting the first buffer structure 2 and the second buffer structure 3, for example, a guide member 7 connected to the fixed base 121, which guides the second buffer structure 3, and the upper end of the guide member 7 limits the second buffer structure 3.

[0103] Specifically, under wind suction conditions, when the wind suction force is large, the support structure 62 may move upward at a high speed in the set direction and collide with the penetrating support 12, potentially affecting the reliability of the entire photovoltaic system. The first buffer structure 2 is configured to buffer the upward movement of the support structure 62 in the set direction, reducing the impact on the support structure 62. When the wind suction force gradually weakens, the support structure 62 may move downward at a high speed in the set direction and collide with the penetrating support 12, potentially affecting the reliability of the entire photovoltaic system. The second buffer structure 3 is configured to buffer the downward movement of the support structure 62 in the set direction, reducing the impact on the support structure 62.

[0104] The specific structures of the first buffer structure 2 and the second buffer structure 3 are not limited; they can be buffer pads or elastic elements, etc.

[0105] like Figure 11-16 In the third embodiment of this disclosure shown, specific reference is made. Figure 13 The first connecting hole 12124 and the second connecting hole 623 extend axially along the Y-axis. The first connecting hole 12124 is an oblong hole extending in a set direction, and the second connecting hole 623 is a round hole. The first connecting member 4 passes through the first connecting hole 12124 and the second connecting hole 623. The first connecting member 4 is axially limited by a pin or nut. The first connecting member 4 can move in a set direction with the longitudinal purlin 622 of the support structure 62. The first buffer structure 2 can be located above the first connecting member 4. For example, the first buffer structure 2 is a buffer pad, which is guided by the guide member 7. The second buffer structure 3 can be located below the first connecting member 4. The second buffer structure 3 is a buffer pad set at the bottom of the groove of the first groove structure 12123.

[0106] like Figure 17-19 As shown, in the fourth embodiment of this disclosure, the first connecting member 4 is arranged vertically, similar to that in the second embodiment (see the second embodiment for reference). Figure 10 The method is similar; for details, please refer to [the relevant documentation]. Figure 18 The first connecting member 4 is arranged vertically, but the penetrating support 12 and the supporting structure 62 can move relative to each other vertically. The first connecting member 4 is axially limited by a pin or nut. The first buffer structure 2 includes a spring, which is sleeved on the first connecting member 4. The lower end of the spring abuts against the longitudinal purlin 622, and the upper end is limited by the upper end of the first connecting member 4. Thus, the first buffer structure 2 can buffer the upward movement of the supporting structure 62 in a set direction, reducing the impact on the supporting structure 62. The second buffer structure 3 can be arranged in a similar manner, but is not shown in the figure. (Reference) Figure 8 The first connecting member 4 can be set as a U-shaped member with the opening facing downward. A spring is sleeved on the U-shaped member, passes through the longitudinal purlin 622 and the fixing seat 121 and is threadedly connected to the nut.

[0107] In the above embodiments, optionally, multiple penetrating supports 12 are distributed on a set enclosure line, and all non-penetrating supports 11 are located inside the area enclosed by the set enclosure line.

[0108] It should be understood that the enclosing line is a virtual closure line, as referenced. Figure 16 Multiple penetrating supports 12 are distributed on a rectangular enclosure line, and all non-penetrating supports 1 are located in the inner area of ​​the rectangle. Other penetrating supports 12 can also be arranged in the inner area of ​​the rectangle.

[0109] like Figure 16As shown, for example, a region is formed by multiple penetrating supports 12 on the outermost side. In this region, non-penetrating supports 11 and penetrating supports 12 are arranged alternately along the Y-axis. Multiple non-penetrating supports 11 and penetrating supports 12 are arranged in sequence along the X-axis, so that all supports are distributed in a matrix of layer 1.

[0110] Thus, all the outer supports 1 adopt through-type supports 12, which can serve as the main support of the support structure 62, while the non-through-type supports 11 serve as the auxiliary support of the support structure 62, which helps to ensure the reliability of the support structure 62.

[0111] Secondly, the photovoltaic system provided in this disclosure includes the support assembly described in the above embodiments.

[0112] like Figure 16 As shown, specifically, the photovoltaic system also includes a support structure 62 and a photovoltaic panel assembly 61. The non-penetrating support 11 and the penetrating support 12 of the support assembly are respectively connected to the support structure 62 and connected to the photovoltaic panel assembly 61 through the support structure 62.

[0113] The support structure 62 includes purlin components, photovoltaic panel components 61 are mounted on the purlin components, and the purlin components are connected to the bracket components.

[0114] In other words, the photovoltaic panel module 61 is connected to the support module through the purlin module, thereby dispersing the gravity or wind suction force of the entire support structure 62 to a certain extent through the purlin module.

[0115] like Figure 16 As shown, the purlin assembly further includes a transverse purlin 621 and a longitudinal purlin 622, which are connected to each other.

[0116] For example, in a set direction, the photovoltaic panel assembly 61, the horizontal purlin 621 and the vertical purlin 622 are distributed from top to bottom and connected in sequence.

[0117] In this way, the purlin module can effectively disperse the gravity or wind suction force of the entire support structure 62, and the stress reliability of the entire photovoltaic system is high.

[0118] While the above disclosure is provided, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this disclosure.
