Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic modules, and specifically to a photovoltaic module carrier and a photovoltaic bracket. 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 installation requirements in different environments. General photovoltaic brackets are fixed to the ground, roof or other structures to keep the photovoltaic modules at a certain tilt angle to maximize the reception of solar radiation. It is impossible to build a three-dimensional photovoltaic bracket on the slope of the colored steel tiles on the roof. Therefore, most of them are currently fixed to the slope of the colored steel tiles by square steel or I-beams, and then the metal connecting plates are fixed to the square steel or I-beams with bolts, and finally the photovoltaic modules are fixed to the metal connecting plates. An existing photovoltaic bracket, such as Figure 1 As shown, it includes a square steel beam 1, a supporting connector 2, an auxiliary frame 5, a rubber pad 6 and a pressing mechanism 4, wherein two supporting connectors 2 are placed on the left and right sides of each square steel beam 1, and an auxiliary frame 5 is slidably assembled on the top of each supporting connector 2. The sliding of the auxiliary frame 5 and the supporting connector 2 is restricted by a locking mechanism. A rubber pad 6 is installed on the upper surface of the auxiliary frame 5, and the rubber pad 6 is bonded to the edge of the photovoltaic module 7 using a double-sided sticker. The pressing mechanism 4 includes a pressing plate, a bolt and a nut. The two ends of the pressing plate press at least two supporting connectors 2 respectively, and then the supporting connector 2 is firmly pressed on the square steel beam 1 with the bolt and the nut. This photovoltaic bracket uses a pressing mechanism 4 to fix at least two supporting connectors 2 at the same time, which facilitates installation and disassembly. Moreover, by releasing the restriction of the locking mechanism on the auxiliary frame 5 and the supporting connector 2, the position of the auxiliary frame 5 can be flexibly changed, that is, the photovoltaic module 7 is flexibly adjusted.

[0003] When the photovoltaic module 7 is installed on the above-mentioned photovoltaic bracket, only the two side edges of the photovoltaic module are bonded to the rubber pads 6 on the two auxiliary frames 5 through double-sided tape. Under the action of wind load, the photovoltaic module is prone to uneven deformation, and there is a risk of hidden cracks. Moreover, the connection strength between the photovoltaic module and the photovoltaic bracket is insufficient. On windy days, the photovoltaic module is easy to separate from the photovoltaic bracket. Utility Model Content

DETAILED DESCRIPTION

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] like Figure 2-Figure 17 As shown, the present application provides a technical solution: a photovoltaic module carrier, used to carry and connect photovoltaic modules, the photovoltaic module carrier is arranged between two adjacent square steel beams 1, or, between the supporting connectors 2 on two adjacent square steel beams 1;

[0050] The photovoltaic module carrier includes a bearing surface and a buffer pad 10, the bearing surface is a plane, and the bearing surface is used to hold up the photovoltaic module;

[0051] The buffer pad 10 has a first surface and a second surface opposite to each other, the first surface is connected to the bearing surface, and the second surface is used to be connected to the photovoltaic module;

[0052] The photovoltaic module carrier includes a second bearing pallet 11, which includes plate body 1, plate body 2 and plate body 3 connected in sequence. Plate body 1 and plate body 3 are respectively connected to two adjacent square steel beams 1, and the upper surface of plate body 2 forms a bearing surface.

[0053] In this embodiment, the bearing surface of the photovoltaic component carrier supports the photovoltaic component 7, and the buffer pad 10 on the bearing surface is also connected to the photovoltaic component 7. Therefore, the contact area between the photovoltaic bracket and the photovoltaic component 7 is increased, and it is no longer dependent on the auxiliary frame 5 to support and connect the photovoltaic component 7. The connection strength between the photovoltaic bracket and the photovoltaic component 7 is improved, thereby avoiding to a certain extent the problem of hidden cracks caused by uneven deformation of the photovoltaic component 7 under the action of wind load, and at the same time greatly reducing the probability of separation between the photovoltaic bracket and the photovoltaic component 7.

[0054] It should be clear that the photovoltaic module carrier can be installed on the square steel beam 1 or the supporting connector 2.

[0055] It should be noted that the buffer pad 10 in this embodiment is preferably an elastic member, such as a rubber pad. Since the rubber pad is elastic, it can compensate for the difference in thermal expansion and contraction between the photovoltaic module 7 and the bearing surface due to temperature changes to a certain extent, thereby avoiding stress deformation of the photovoltaic module 7. The bottom surface of the rubber pad is bonded to the bearing surface, and the top surface thereof is bonded to the bottom surface of the photovoltaic module 7 through a double-sided tape.

[0056] In this embodiment, there are multiple options for the shape and installation position of the photovoltaic component carrier, as long as it can effectively support and connect the photovoltaic components 7.

[0057] Exemplarily, the photovoltaic module carrier includes a first carrier plate 9, such as Figure 2 and Figure 3 As shown, the first bearing support plate 9 includes a first plate body 901 and a second plate body 902 connected to each other, wherein one end of the first plate body 901 away from the second plate body 902 is integrally formed with the supporting connector 2. Figure 2 As shown, the second plate body 902 is parallel to the photovoltaic assembly 7, and the upper surface of the second plate body 902 forms the above-mentioned bearing surface, on which the buffer pad 10 is installed.

[0058] Such as Figure 2 As shown, the two side edges of each photovoltaic module 7 are supported by two auxiliary frames 5, and are also supported by the first bearing plates 9 on the two supporting connectors 2. In this way, the contact area between the photovoltaic bracket and the photovoltaic module 7 is increased, the photovoltaic bracket can support the photovoltaic module 7 more stably, and the connection strength between the photovoltaic bracket and the photovoltaic module 7 is also effectively enhanced.

[0059] It should be noted that the second plate 902 and the first plate 901 can be arranged vertically or inclined relative to each other, that is, the angle formed between the second plate 902 and the first plate 901 is an obtuse angle or an acute angle. No specific limitation is made here.

[0060] Optionally, the first bearing support plate 9 can also be installed on the square steel beam 1 by welding or bolting. That is, the first plate body 901 is fixed to the square steel beam 1 by welding or bolting.

[0061] It should be clear that in order to ensure that the second plate 902 can effectively support the photovoltaic module 7, the length of the second plate 902 in the horizontal direction should be guaranteed to be at a certain length, that is, the end surface of the second plate 902 should be as close as possible to the middle position of the side of the photovoltaic module 7, that is, to achieve the following Figure 2 Status shown.

[0062] For example, Figure 4 and Figure 5As shown, this embodiment provides another photovoltaic module carrier, including a second bearing pallet 11, the second bearing pallet 11 includes a plate body 1, a plate body 2 and a plate body 3 connected in sequence, the plate body 1 and the plate body 3 are respectively connected to two adjacent square steel beams 1, the upper surface of the plate body 2 forms a bearing surface, and a buffer pad 10 is installed on the upper surface of the plate body 2.

[0063] It should be clear that if Figure 5 As shown, the length of the second plate is slightly smaller than the distance between two adjacent square steel beams 1 so as to maximize the fit and support of the photovoltaic module 7 .

[0064] In addition, the plate body 1 and the plate body 2 can be fixed to the square steel beam 1 by welding, or by using the first bolt 13. Of course, if the first bolt 13 is used, the side surfaces of the plate body 1, the plate body 2 and the square steel beam 1 are provided with holes for the first bolt 13 to pass through.

[0065] It should be noted that, in this embodiment, there is no specific limitation on the angle between the plate body 1 and the plate body 2 and the angle between the plate body 3 and the plate body 2. For example, they may be 90° or 120°.

[0066] Optionally, in order to improve the structural strength of the second bearing support plate 11, reinforcing ribs may be welded between plate body 1 and plate body 2, and reinforcing ribs may be welded between plate body 2 and plate body 3. The shape and number of the reinforcing ribs are not specifically limited.

[0067] In addition, optional Figure 6 As shown, the photovoltaic module carrier includes a third bearing tray 12, which is arranged between two supporting connectors 2. The third bearing tray 12 includes a plate body 1, a plate body 2 and a plate body 3 connected to each other. The plate body 1 and the plate body of the third bearing tray 12 are respectively connected to the two supporting connectors 2. Specifically, the third bearing tray 12 and the two second supporting connectors 2 are integrally formed. In this way, the third bearing tray 12 is also fixed while the supporting connector 2 is pressed onto the square steel beam 1 by using a clamping mechanism, and it is not necessary to use bolts for installation, which is more convenient to use.

[0068] For example, Figure 7 As shown, this embodiment provides another photovoltaic module carrier, which includes a fourth carrier plate 14, which is in the shape of a corrugated plate, and the outer contour of the cross section of the fourth carrier plate 14 perpendicular to its extension direction is rectangular, and the upper surface of the fourth carrier plate 14 forms a bearing surface, and a buffer pad 10 is bonded to the upper surface of the fourth carrier plate 14. In this embodiment, as Figure 7 The two ends of the fourth bearing support plate 14 are respectively connected to two adjacent square steel beams 1 through the first bolts 13 .

[0069] Specifically, the fourth load-bearing support plate 14 is composed of a vertical plate arranged vertically and a horizontal plate arranged horizontally, and a reinforcing plate is respectively provided between each horizontal plate and two adjacent vertical plates, and the two reinforcing plates on each horizontal plate form a V-shaped structure. The strength of the fourth load-bearing support plate 14 is enhanced by the provided reinforcing plates, so as to support the photovoltaic module more stably.

[0070] Optionally, two ends of the fourth load-bearing tray 14 are respectively integrally formed with two supporting connectors 2 .

[0071] For example, Figure 8 As shown, this embodiment provides another photovoltaic component carrier, which includes a fifth carrier pallet 15, which is in the shape of a corrugated plate, and the outer contour of the cross section of the fifth carrier pallet 15 perpendicular to its extension direction is an isosceles trapezoid, and the upper surface of the fifth carrier pallet 15 forms a bearing surface.

[0072] In this embodiment, the two ends of the fifth bearing support plate 15 are respectively connected to the two adjacent square steel beams 1 by bolts. It can also be formed integrally with the two supporting connectors 2, that is, Figure 8 Status shown.

[0073] It should be noted that the fifth bearing pallet 15 includes a support member, a first inclined portion 151, a corrugated horizontal portion 152, and a second inclined portion 153 connected in sequence. The first end of each support member is connected to the first inclined portion 151, and the second end of each support member is connected to the second inclined portion 153. In this embodiment, the support member is used to support the first inclined portion 151 and the second inclined portion 153, thereby preventing the first inclined portion 151 and the second inclined portion 153 from being deformed after being subjected to external force, thereby improving the overall strength of the fifth bearing pallet 15.

[0074] In the embodiment of the present application, there is no restriction on the shape and structure of the support member. It is only necessary that the support member can provide support force for the first inclined portion 151 and the second inclined portion 153. For example, in the embodiment of the present application, the support member can be configured as a support rod or a support sheet.

[0075] In the embodiment of the present application, the support member can be connected to the first inclined portion 151 and the second inclined portion 153 in any suitable manner. For example, the support member can be welded or integrally connected to the first inclined portion 151 and the second inclined portion 153. Alternatively, the support member can be detachably connected to the first inclined portion 151 and the second inclined portion 153 by bolts.

[0076] As a specific embodiment, Fig. 9As shown, the support member includes a first support plate, a second support plate and a third support plate which are connected in sequence, wherein the first support plate is fixed to the inner wall of the first inclined portion 151 by bolts, the second support plate is fixed to the inner top wall of the corrugated horizontal portion 152 by bolts, and the third support plate is fixed to the inner wall of the second inclined portion 153 by bolts.

[0077] In this embodiment, the photovoltaic module carrier also includes two edge protection mechanisms 16, which are detachably connected to the carrier surface and are used to limit the movement of the photovoltaic module along its thickness direction and to protect the two opposite sides of the photovoltaic module.

[0078] Specifically, Fig.13 As shown, the edge protection mechanism 16 includes an edge protection seat 161, which includes a fixed plate, an edge protection plate and a limit plate connected in sequence, wherein the edge protection plate is perpendicular to the upper surface of the fixed plate, and the limit plate is fixed to the top of the edge protection plate and parallel to the fixed plate. A threaded hole is opened on the fixed plate.

[0079] As a preferred embodiment, a first elastic pad 162 is installed on the lower surface of the limiting plate, and a second elastic pad 163 is installed on the side of the edge guard plate facing the photovoltaic module.

[0080] The following is to install the edge protection mechanism 16 to Figure 4 The situation on the second bearing tray 11 in the embodiment is described in detail:

[0081] like Fig. 9 As shown, Fig. 9 The direction perpendicular to the paper surface and facing inward is recorded as the front-to-back direction, and the two edge protection mechanisms 16 are respectively installed in the front-to-back directions of the second bearing support plate 11. Fig.10 Status shown.

[0082] Specifically, the two edge guards 161 are respectively inserted into the front and rear end surfaces of the photovoltaic module 7, at which time the fixing plate is attached to the lower surface of the second plate body of the second bearing tray 11, and the second elastic pad 163 on the edge guard plate is attached to the front end surface or the rear end surface of the photovoltaic module 7, while the limit plate is higher than the upper surface of the photovoltaic module 7, and the first elastic pad 162 is attached to the top surface of the photovoltaic module 7. Then, the second bolt 17 is used to fix the fixing plate to the second plate body 902 of the second bearing tray 11.

[0083] Since the limiting plate restricts the photovoltaic assembly 7, it is difficult for the photovoltaic assembly 7 to break away from the photovoltaic bracket in the vertical direction under the action of wind, thereby greatly improving the installation stability of the photovoltaic assembly 7. In addition, since the edge guard is close to the side of the photovoltaic assembly 7, and cooperates with the auxiliary frame 5 on both sides of the photovoltaic assembly 7, the four sides of the photovoltaic assembly 7 can be completely protected, avoiding the side of the photovoltaic assembly 7 from being worn and improving its service life.

[0084] It should be noted that the length and number of the edge protection seats 161 in the edge protection mechanism 16 need to be set according to the shapes of different bearing pallets.

[0085] For example, installing to Figure 2 The length of the edge guard seat 161 on the first bearing support plate 9 is slightly smaller than the distance between the two square steel beams 1, and an edge guard seat 161 is installed between the two adjacent first bearing support plates 9 in the two adjacent square steel beams 1. The two ends of the edge guard seat 161 are respectively connected to the second plate bodies 902 on the two adjacent first bearing support plates 9 on the two square steel beams 1 by bolts.

[0086] For example, install to Figure 7 There are multiple edge guard seats 161 on the fourth load-bearing tray 14, and the length of the edge guard seat 161 is slightly smaller than the length of the horizontal plate on the fourth load-bearing tray 14, and the edge guard seat 161 is installed to the horizontal plate at the high point of the fourth load-bearing tray 14 using bolts.

[0087] For example, install to Figure 8 There are multiple edge guard seats 161 on the fifth bearing tray 15, and the length of the edge guard seat 161 is slightly smaller than the length of the corrugated horizontal portion 152. The edge guard seat 161 is installed on the corrugated horizontal portion 152 at a high position of the fifth bearing tray 15 using bolts.

[0088] After introducing the photovoltaic component carrier 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 photovoltaic component carrier proposed in any one of the above embodiments, an auxiliary frame 5, a supporting connector 2 and a clamping mechanism.

[0089] Among them, Fig.14 As shown, the supporting connector 2 includes a bottom plate 201, a supporting plate 202, a slider 203, a top block 205 and a bottom block 206 which are connected in sequence, wherein the supporting plate 202 is vertically fixed on the bottom plate 201, the slider 203 is fixed on the top of the supporting plate 202, and the slider 203 and the bottom plate 201 are parallel. Further, the top block 205 and the bottom block 206 are respectively fixed on the lower surface of the slider 203 and the upper surface of the bottom plate 201, and the top block 205 and the bottom block 206 are both located on the same side of the supporting plate 202, the top block 205 is located above the bottom block 206, there is a certain distance between the lower surface of the top block 205 and the upper surface of the bottom block 206, and the right side surface of the top block 205 and the right side surface of the bottom block 206 are located in the same vertical plane. Thus, a slot 204 is formed between the bottom plate 201, the support plate 202, the slider 203, the top block 205 and the bottom block 206. Fig.15From the perspective of the structure, the card slot 204 is divided into two parts, namely, slot body one and slot body two, wherein slot body one is formed between the top block 205 and the bottom block 206, and slot body two is formed between the right side of the top block 205, the right side of the bottom block 206, the left side of the support plate 202, the top surface of the bottom plate 201 and the lower surface of the slider 203.

[0090] In this embodiment, if Fig.14 As shown, the auxiliary frame 5 includes a connected substrate 501 and a support plate 502, wherein the support plate 502 is vertically arranged on the upper surface of the substrate 501, wherein the support plate 502 plays the role of edge protection, protecting the side of the photovoltaic module 7 from damage such as external collision and scratching, and effectively extending the service life of the photovoltaic module 7. A slide groove is provided on the lower surface of the substrate 501, and the slide groove extends from one end of the auxiliary frame 5 to the other end thereof. The cross section of the slide groove is T-shaped, and accordingly, the slider 203 is a T-shaped block. A locking mechanism is installed between the auxiliary frame 5 and the slider 203, and the locking mechanism is used to limit the sliding of the auxiliary frame 5 relative to the slider 203.

[0091] In this embodiment, the locking mechanism includes a locking bolt 8, a first threaded hole is opened on the side of the slider 203, and a second threaded hole is opened on the side of the base plate 501. The second threaded hole is connected to the slide groove, and the axis of the first threaded hole and the axis of the second threaded hole are located in the same horizontal plane.

[0092] When fixing the auxiliary frame 5 to prevent the auxiliary frame 5 from sliding relative to the supporting connector 2, it is only necessary to insert the locking bolt 8 into the second threaded hole corresponding to the base plate 501 and then tighten the locking bolt 8, and the locking bolt 8 is further screwed into the first threaded hole of the slider 203.

[0093] In this embodiment, a rubber pad 6 is installed on the upper surface of the substrate 501, and the upper surface and lower surface of the rubber pad 6 are respectively bonded to the photovoltaic module 7 and the substrate 501 using double-sided tape. Since the rubber pad 6 has excellent buffering performance and deformation ability, it can provide expansion and deformation avoidance space for the photovoltaic module 7 and the auxiliary frame 5.

[0094] Optionally, a rubber pad is also installed on the side of the backboard 502 that is in contact with the photovoltaic component 7. The rubber pad is used to prevent the backboard 502 from directly contacting the side of the photovoltaic component 7, so that the auxiliary frame 5 will not damage the side of the photovoltaic component 7 while protecting the side of the photovoltaic component 7.

[0095] Preferably, the pressing mechanism comprises a first pressing member 4, the first pressing member 4 comprises a lower pressing plate member, the lower pressing plate member is as follows: Fig.15, which includes a first pressing plate 401, two first inclined plates 402, two clamping blocks, a first locking bolt 405 and a first locking nut 406. The two first inclined plates 402 are respectively connected to the left and right sides of the first pressing plate 401. The first end of the first inclined plate 402 is connected to the end of the first pressing plate 401. The second end of the first inclined plate 402 is higher than the first pressing plate 401. The angle formed between the first inclined plate 402 and the first pressing plate 401 is an obtuse angle. The clamping block includes a first horizontal plate 403 and a first vertical plate 404 connected to each other. The first horizontal plate 403 and the first vertical plate 404 are perpendicular to each other. The end of the first horizontal plate 403 in the clamping block away from the first vertical plate 404 is connected to the end of the first inclined plate 402. The angle formed between the first inclined plate 402 and the first horizontal plate 403 is also an obtuse angle. A hole for the first locking bolt 405 to pass through is provided in the middle position of the width direction of the first pressing plate 401.

[0096] Furthermore, the first vertical plate 404 is adapted to the second groove of the supporting connector 2, and the distance between the lower surface of the first vertical plate 404 and the lower surface of the first horizontal plate 403 is the same as the height of the bottom block 206. In this way, when fixing the supporting connector 2, the two clamping blocks can be aligned with the clamping grooves 204 of the two supporting connectors 2 at the same time, and then the first pressing member 4 is pushed, the first vertical plate 404 is completely embedded in the second groove, and the lower surface of the first horizontal plate 403 is in contact with the upper surface of the top block 205, and finally the first locking bolt 405 and the first locking nut 406 are used to fix the first pressing plate 401 to the square steel beam 1.

[0097] It should be clear that when the block pieces on both sides of the first pressing piece 4 are respectively inserted into the supporting connecting pieces 2 on both sides of the top of the square steel beam 1, Figure 1 As shown, at this time, the lower surface of the first pressing plate 401 is higher than the top surface of the square steel beam 1, so as to provide the first pressing plate 401 with downward movement space, so as to ensure that the blocking parts on both sides of the first pressing plate 401 can apply pressure to the supporting connecting parts 2 on both sides.

[0098] It should be clear that in this embodiment, the first vertical plate 404 of the clamping mechanism is inserted into the second groove of the supporting connector 2 to restrict the supporting connector 2 and prevent the supporting connector 2 from moving laterally or jerking under external force impact.

[0099] It should be noted that the supporting connector 2 is formed by metal machining, that is, the bottom plate 201, the supporting plate 202, the sliding block 203, the top block 205 and the bottom block 206 are integrally formed. Preferably, aluminum alloy or steel is used for machining.

[0100] In this embodiment, the first pressing plate 401 , the two first inclined plates 402 , the two first horizontal plates 403 , and the two first vertical plates 404 are integrally formed metal parts, preferably made of aluminum alloy or steel.

[0101] In this embodiment, the first clamping member 4 can simultaneously fix the support connectors 2 on both sides of the top of the square steel beam 1, thereby improving the installation efficiency and saving the installation time. When the support connector 2 is subsequently removed, it is only necessary to loosen the first locking nut 406 to release the pressure on the support connector 2, which greatly facilitates the disassembly of the support connector 2 and improves the disassembly efficiency of the photovoltaic bracket.

[0102] As another alternative embodiment, Fig.16 As shown, the clamping mechanism includes two second clamping members 18, two second locking bolts 185 and two second locking nuts 186. The structures of the two second clamping members 18 are exactly the same. The two second clamping members 18 respectively fix the supporting connecting members 2 on the left and right sides of the square steel beam 1 to the square steel beam 1.

[0103] Specifically, Fig.17 and Fig.18 As shown, the second pressing member 18 is different from the first pressing member 4 described above. The second pressing member 18 in this embodiment includes a second pressing plate 181, a second inclined plate 182, a second horizontal plate 183 and a second vertical plate 184 connected in sequence, wherein the width of the second pressing plate 181 (i.e. Fig.18 The length of the second pressing plate 181 from the left end to the right end is smaller than the width of the first pressing plate 401 of the first pressing member 4, and a hole is provided at the top of the second pressing plate 181 for the second locking bolt 185 to pass through. The second inclined plate 182, the second horizontal plate 183 and the second vertical plate 184 have the same structure as the first inclined plate 402, the first horizontal plate 403 and the first vertical plate 404.

[0104] In this embodiment, when the second horizontal plate 183 and the second vertical plate 184 in the second clamping member 18 are simultaneously inserted into the slot 204 of the supporting connector 2, the lower surface of the second clamping plate 181 is higher than the upper surface of the square steel beam 1. Then, the second locking bolt 185 is used to pass through the hole at the top of the square steel beam 1 and the hole on the second clamping plate 181 in sequence from bottom to top, and finally the second locking nut 186 is screwed on the top of the second locking bolt 185 and tightened, and the second locking nut 186 applies a downward force to the second clamping plate 181, and the second vertical plate 184 and the second horizontal plate 183 simultaneously apply a downward pressure to the supporting connector 2, thereby pressing the supporting connector 2 onto the square steel beam 1.

[0105] It can be seen that in this embodiment, two second clamping members 18 are used to cooperate with the supporting connecting members 2 on the left and right sides of the square steel beam 1, so that the second vertical plates 184 of the two second clamping members 18 are respectively inserted into the grooves 204 on the supporting connecting members 2 on the left and right sides of the square steel beam 1, and then the second locking bolts 185 and the second locking nuts 186 are used to fix the second pressure plates 181 of the two second clamping members 18 to the top of the square steel beam 1.

[0106] The method of using the first clamping member 4 to fix the supporting connecting members 2 on the left and right sides of the square steel beam 1 has the following problem: Fig.13 If the supporting connector 2 on the left side is damaged and needs to be repaired or replaced, the first clamping member 4 needs to be removed. At this time, although the supporting connector 2 on the left side can be removed, the supporting connector 2 on the right side is no longer fixed by the first clamping member 4. The lack of effective fixation will cause the photovoltaic component 7 on the right side of the square steel beam 1 to be in an unstable state.

[0107] In this embodiment, two second clamping members 18 are used to fix the supporting connectors 2 on the left and right sides of the square steel beam 1 respectively. In this way, when the supporting connector 2 on the left side of the square steel beam 1 needs to be replaced, it is only necessary to remove the supporting connector 2 on that side, which greatly facilitates subsequent maintenance and replacement work.

[0108] 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.
