DETAILED DESCRIPTION

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] like Figure 2-Figure 13As shown, the present application provides a technical solution: a bracket connector, used to connect a square steel beam 1 and a photovoltaic module 7, comprising a first support connector 2, an auxiliary frame 5, a clamping mechanism, a locking bolt and a locking nut, wherein the first support connector 2 is arranged on the bearing surface of the square steel beam 1, and the auxiliary frame 5 is slidably assembled on the first support connector 2;

[0044] The clamping mechanism includes a lower pressing plate, at least one side of which is provided with a block member, and the first supporting connecting member 2 includes a first base, and the first base is provided with at least one card slot 204 adapted to the block member;

[0045] When the clamping block of the lower pressing plate is inserted into the clamping groove 204 of the first base, the lower surface of the lower pressing plate is higher than the bearing surface of the square steel beam 1;

[0046] The locking bolts pass through the bearing surface of the square steel beam 1 and the lower pressing plate in sequence, and the locking nuts are screwed to the tops of the locking bolts and are higher than the lower pressing plate.

[0047] It should be noted that a photovoltaic bracket designed by our company, such as Figure 1 As shown, it includes a square steel beam 1, a bearing connector 3, an auxiliary frame 5 and a rubber pad 6. The bottom end of the bearing connector 3 is fixedly installed on the square steel beam 1 by bolts. The lower surface of the auxiliary frame 5 is provided with a slide groove, and the top of the bearing connector 3 cooperates with the slide groove. A threaded hole is opened on the side of the auxiliary frame 5, and a threaded hole is also opened on the side of the top of the bearing connector 3. When fixing the auxiliary frame 5 and the bearing connector 3, the bolts are screwed into the threaded holes on the side of the auxiliary frame 5 and tightened. The rubber pad 6 is installed on the upper surface of the auxiliary frame 5, and the edge of the lower surface of the photovoltaic module 7 is bonded to the rubber pad 6. In this photovoltaic bracket, since the bearing connector 3 and the auxiliary frame 5 are only locked by bolts, after the bolt lock is released, the auxiliary frame 5 can slide relative to the bearing connector 3, so it can play the effect of changing the position of the photovoltaic module 7. Moreover, the rubber pad 6 is elastic and can compensate for the difference in thermal expansion and contraction between the photovoltaic module 7 and the auxiliary frame 5 due to temperature changes to a certain extent, thereby avoiding stress deformation of the photovoltaic module 7.

[0048] Different from the above-mentioned photovoltaic bracket, in this embodiment, when installing the photovoltaic module 7, the square steel beam 1 is fixed to the color steel tile by a fixed connection method such as welding or bolts, and then the first support connecting member 2 is placed on the left and right sides of the top surface of the square steel beam 1, and then the block member at the end of the lower pressure plate is inserted into the slot 204 of the first support connecting member 2, and then the locking bolt is inserted from bottom to top, so that the locking bolt passes through the top surface of the square steel beam 1 and the lower pressure plate in turn, and finally the locking nut is screwed into the top of the locking bolt and tightened, the locking nut gives a downward force to the lower pressure plate, and the lower pressure plate simultaneously acts on the first support connecting member 2, thereby tightly pressing the first support connecting member 2.

[0049] It should be clear that the block member on the lower pressing plate member can be arranged on one side of the lower pressing plate member, or the block member can be arranged on both sides of the lower pressing plate member.

[0050] If, blocking pieces are provided on both sides of the lower pressure plate, then the two blocking pieces on the left and right sides of the lower pressure plate can be simultaneously inserted into the first supporting connecting pieces 2 on the left and right sides of the top surface of the square steel beam 1. At this time, only one such clamping mechanism is needed to simultaneously fix and clamp the first supporting connecting pieces 2 on the left and right sides of the top surface of the square steel beam 1 to the square steel beam 1.

[0051] If only one side of the lower pressure plate is provided with a clamping block, two such clamping mechanisms are required, and the first supporting connectors 2 on the left and right sides of the top surface of the square steel beam 1 are fixed and clamped to the square steel beam 1 respectively.

[0052] It can be seen that compared with Figure 1 In the photovoltaic bracket in this embodiment, the first support connector 2 is fixed by the cooperation of the lower pressure plate, the locking bolt and the locking nut, thereby improving the installation efficiency and saving the installation time. When the first support connector 2 is subsequently removed, it is only necessary to loosen the locking nut and release the pressure of the lower pressure plate on the first support connector 2, which greatly facilitates the disassembly of the first support connector 2 and improves the disassembly efficiency of the photovoltaic bracket.

[0053] As a first specific embodiment, Figure 2 and Figure 3 As shown, the clamping mechanism includes a first clamping member 4 , which includes a lower clamping plate, block members arranged on both sides of the lower clamping plate, a first locking bolt 405 and a first locking nut 406 .

[0054] When using the first clamping piece 4 to fix the first supporting connecting piece 2 on the left and right sides of the top of the square steel beam 1, the first supporting connecting piece 2 can be installed from the left and right sides of the first clamping piece 4 respectively, and the blocking piece on the left side of the lower pressing plate is inserted into the blocking groove 204 of the first supporting connecting piece 2 on the left side of the square steel beam 1. At the same time, the blocking piece on the right side of the lower pressing plate is inserted into the blocking groove 204 of the first supporting connecting piece 2 on the right side of the square steel beam 1. Then the first locking bolt 405 is inserted from bottom to top, so that the first locking bolt 405 passes through the top surface of the square steel beam 1 and the lower pressing plate in turn, and finally the first locking nut 406 is screwed into the top end of the first locking bolt 405 and tightened. The first locking nut 406 gives a downward force to the lower pressing plate, and the two ends of the lower pressing plate act on the two first supporting connecting pieces 2 at the same time, so that the two first supporting connecting pieces 2 can be tightly pressed, thereby achieving the effect of fixing the two first supporting connecting pieces 2 at the same time.

[0055] It can be seen that compared with Figure 1In the photovoltaic bracket, in this embodiment, by using the mutual cooperation of the lower pressure plate, the first locking bolt 405 and the first locking nut 406, at least two first support connectors 2 can be fixed at the same time, thereby improving the installation efficiency and saving the installation time. When the first support connector 2 is subsequently removed, it is only necessary to loosen the first locking nut 406 and release the pressure of the lower pressure plate on the first support connector 2, which greatly facilitates the disassembly of the first support connector 2 and improves the disassembly efficiency of the photovoltaic bracket. Moreover, the block members at both ends of the lower pressure plate can be inserted into the card slots 204 of at least two first support connectors 2 at the same time to better limit the first support connector 2, prevent the first support connector 2 from moving under external impact, and prevent the lower pressure plate and the first support connector 2 from slipping.

[0056] It should be clear that in this embodiment, two rows of first supporting connectors 2 can be provided, and two rows of first supporting connectors 2 can be fixed simultaneously using a long strip of lower pressing plate, so that two rows of first supporting connectors 2 can be fixed at one time, and subsequent disassembly is also very convenient.

[0057] As a preferred embodiment, Figure 3 and Figure 4 As shown, the first supporting connector 2 includes a first base, and the first base includes a first bottom plate 201, a first supporting plate 202, a first slider 203, a top block 205 and a bottom block 206 connected in sequence, wherein the first supporting plate 202 is vertically fixed on the first bottom plate 201, the first slider 203 is fixed on the top of the first supporting plate 202, and the first slider 203 and the first bottom plate 201 are parallel. Further, the top block 205 and the bottom block 206 are respectively fixed to the lower surface of the first slider 203 and the upper surface of the first bottom plate 201, and the top block 205 and the bottom block 206 are both located on the same side of the first 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. In this way, a slot 204 is formed between the first bottom plate 201, the first support plate 202, the first slider 203, the top block 205 and the bottom block 206. Figure 4 From the perspective of the embodiment, the card slot 204 is divided into two parts, namely, the slot body 1 and the slot body 2, wherein the slot body 1 is formed between the top block 205 and the bottom block 206, and the slot body 2 is formed between the right side of the top block 205, the right side of the bottom block 206, the left side of the first support plate 202, the top surface of the first bottom plate 201 and the lower surface of the first slider 203;

[0058] Further, such as Figure 3 and Figure 5As shown, the block member in the first pressing member 4 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, and one end of the first horizontal plate 403 away from the first vertical plate 404 is connected to the end of the lower pressing plate member. Figure 3 As shown, the first vertical plate 404 is matched with the second trough body, 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 the first clamping member 4 is used to fix the first supporting connectors 2 on the left and right sides of the top of the square steel beam 1, the two clamping blocks can be simultaneously aligned with the clamping grooves 204 of two or two rows of first supporting connectors 2, and then the lower pressing plate is pushed, and the first vertical plate 404 is completely embedded in the second trough body, 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 lower pressing plate to the square steel beam 1.

[0059] It should be clear that in this embodiment, the first vertical plates 404 on the left and right sides of the first clamping member 4 are inserted into the groove bodies 2 of the first supporting connectors 2 on both sides, thereby restricting the first supporting connectors 2 to prevent the first supporting connectors 2 from moving laterally or jerking under external force impact.

[0060] In addition, when the lower pressure plate is under stress, the lower surface of the first horizontal plate 403 acts on the upper surface of the top block 205, and the lower surface of the first vertical plate 404 acts on the upper surface of the first bottom plate 201. In this way, there are more stress points at the end of the lower pressure plate and the stress is more dispersed.

[0061] In this embodiment, if Figure 5 As shown, the lower pressing plate in the first pressing member 4 includes a first pressing plate 401 and two first inclined plates 402, 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, and the angle formed between the first inclined plate 402 and the first pressing plate 401 is an obtuse angle. The end of the first horizontal plate 403 in the block member away from the first vertical plate 404 is connected to the end of the first inclined plate 402, that is, 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 in the width direction of the first pressing plate 401.

[0062] 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.

[0063] The first supporting connector 2 is formed by metal machining, that is, the first bottom plate 201, the first supporting plate 202, the first sliding block 203, the top block 205 and the bottom block 206 are formed in one piece, preferably by machining of aluminum alloy or steel.

[0064] As another specific embodiment, Figure 7 As shown, the clamping mechanism includes two second clamping members 12, two second locking bolts 125 and two second locking nuts 126. The second clamping member 12 includes a lower clamping plate and a block member, which is arranged on one side of the lower clamping plate. Unlike the above-mentioned first clamping member 4, only one block member is provided in the second clamping member 12 in this embodiment.

[0065] In this embodiment, the lower pressing plate member in the second pressing member 12 includes a second pressing plate 121 and a second inclined plate 122 connected to each other, and the block member includes a second horizontal plate 123 and a second vertical plate 124 connected to each other, and one end of the second horizontal plate 123 away from the second vertical plate 124 is connected to one end of the second inclined plate 122. The difference between the second pressing member 12 and the first pressing member 4 is that only one block member is provided, and the width of the second pressing plate 121 ( Fig. 9 The distance from the left side to the right side of the second pressing plate 121 is less than the width of the first pressing plate 401. The second inclined plate 122, the second transverse plate 123 and the second vertical plate 124 have the same structure as the first inclined plate 402, the first transverse plate 403 and the first vertical plate 404 described above.

[0066] In this embodiment, when the second horizontal plate 123 and the second vertical plate 124 in the second clamping member 12 are simultaneously inserted into the slot 204 of the first supporting connector 2, the lower surface of the second clamping plate 121 is higher than the upper surface of the square steel beam 1. Then, the second locking bolt 125 is used to pass through the hole at the top of the square steel beam 1 and the hole on the second clamping plate 121 in sequence from bottom to top, and finally the second locking nut 126 is screwed on the top of the second locking bolt 125 and tightened, and the second locking nut 126 applies a downward force to the second clamping plate 121, and the second vertical plate 124 and the second horizontal plate 123 simultaneously apply a downward pressure to the first supporting connector 2, thereby pressing the first supporting connector 2 onto the square steel beam 1.

[0067] It can be seen that in this embodiment, two second clamping members 12 are used to cooperate with the first supporting connecting members 2 on the left and right sides of the square steel beam 1, so that the second vertical plates 124 of the two second clamping members 12 are respectively inserted into the grooves 204 on the first supporting connecting members 2 on the left and right sides of the square steel beam 1, and then the second locking bolts 125 and the second locking nuts 126 are used to fix the second pressure plates 121 of the two second clamping members 12 to the top of the square steel beam 1.

[0068] The method of using the first clamping member 4 to fix the first supporting connecting members 2 on the left and right sides of the square steel beam 1 has the following problem: Fig.13 If the first 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 first supporting connector 2 on the left side can be removed, the first 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.

[0069] In this embodiment, two second clamping parts 12 are used to fix the first supporting connecting parts 2 on the left and right sides of the square steel beam 1 respectively. In this way, when the first supporting connecting part 2 on the left side of the square steel beam 1 needs to be replaced, it is only necessary to remove the first supporting connecting part 2 on that side, which greatly facilitates the subsequent maintenance and replacement work.

[0070] As a specific embodiment, the auxiliary frame 5 includes a connected substrate 501 and a backing plate 502, wherein the backing plate 502 is vertically arranged on the upper surface of the substrate 501, wherein the backing plate 502 plays an edge protection function, protects the side of the photovoltaic module 7 from damage such as external collision and scratching, and effectively prolongs 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 first slider 203 is a T-shaped block. A locking mechanism is installed between the auxiliary frame 5 and the first slider 203, and the locking mechanism is used to limit the sliding of the auxiliary frame 5 relative to the first slider 203.

[0071] In this embodiment, the locking mechanism includes a locking bolt 8, a first threaded hole is opened on the side of the first 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.

[0072] When fixing the auxiliary frame 5 to prevent the auxiliary frame 5 from sliding relative to the first 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 first slider 203.

[0073] It should be noted that there is no specific limitation on the number of the first threaded holes on the first slider 203 and the second threaded holes on the side surface of the substrate 501 , as long as they are reasonable.

[0074] In this embodiment, if Figure 2As shown, 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.

[0075] 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.

[0076] As another locking mechanism, Figure 6 As shown, the locking mechanism includes a first magnetic block 9 and a second magnetic block 10 that attract each other, wherein at least one first mounting groove for mounting the first magnetic block 9 is provided on the upper surface of the first slider 203, and at least one second mounting groove for mounting the second magnetic block 10 is provided on the inner top wall of the slide groove of the substrate 501. The first magnetic block 9 is installed in the first mounting groove of the substrate 501, and the second magnetic block 10 is installed in the second mounting groove on the inner top wall of the slide groove. The mutual attraction of the first magnetic block 9 and the second magnetic block 10 is utilized to fix the auxiliary frame 5 and the first supporting connector 2, and it is also convenient to flexibly change the position of the auxiliary frame 5 later. It should be noted that there is no specific restriction on the number of the first magnetic block 9 and the second magnetic block 10, and they can be reasonably set according to the length of the auxiliary frame 5 and the first supporting connector 2.

[0077] As an optional embodiment, in order to improve the stability of the photovoltaic assembly 7 when it is installed on the square steel beam 1, or in other words, to improve the bearing capacity of the bracket connector for the photovoltaic assembly 7. Fig.10 and Fig.11 As shown, the first supporting connector 2 also includes a connecting plate 207, a supporting plate 208 and a buffer pad 209, wherein the first end of the connecting plate 207 is connected to a side of the first base plate 201 away from the bottom block 206, the second end of the connecting plate 207 is connected to the supporting plate 208, the supporting plate 208 is parallel to the first base plate 201, and the buffer pad 209 is fixed to the upper surface of the supporting plate 208.

[0078] like Fig.10 As shown, the lower surface of the photovoltaic component 7 rests on the auxiliary frame 5 and the buffer pad 209 of the carrier plate 208 at the same time, and the lower surface of the photovoltaic component 7 is bonded to the buffer pad 209 , and the carrier plate 208 is used to hold up the photovoltaic component 7 .

[0079] Exemplarily, the connecting plate 207 is disposed perpendicularly to the first bottom plate 201. Alternatively, the connecting plate 207 is disposed obliquely to the first bottom plate 201, and the angle formed between the connecting plate 207 and the first bottom plate 201 is an obtuse angle.

[0080] As another bracket connector, such as Fig.12 As shown, the bracket connector includes the above-mentioned first support connector 2, the first locking bolt 405, the first locking nut 406, the auxiliary frame 5 and the second support connector 11 in this embodiment.

[0081] The structure of the second supporting connector 11 in this embodiment is different from that of the first supporting connector 2. Specifically, Fig.13 , which is the same as the first supporting connector 2, is that the second supporting connector 11 includes a second bottom plate 111, a second supporting plate 112, and a second slider 113 connected to each other. The second bottom plate 111, the second supporting plate 112, and the second slider 113 are respectively the same as the first bottom plate 201, the first supporting plate 202, and the first slider 203 in the first supporting connector 2.

[0082] The difference is that the second supporting connector 11 also includes a force-bearing plate 114 and an inserting plate 116 , wherein one end of the force-bearing plate 114 is fixedly connected to the side of the second supporting plate 112 , the second end of the force-bearing plate 114 is fixedly connected to the inserting plate 116 , and the force-bearing plate 114 is perpendicular to the inserting plate 116 .

[0083] It should be clear that the plug plate 116 is compatible with the second groove in the first supporting connector 2, and the distance between the lower surface of the force-bearing plate 114 and the lower surface of the plug plate 116 is the same as the height of the bottom block 206 in the first supporting connector 2. In addition, a circular hole is provided in the middle of the force-bearing plate 114 for the first locking bolt 405 to pass through.

[0084] like Fig.12 As shown, when the photovoltaic module 7 is fixed by using the bracket connector, the plug plate 116 of the second support connector 11 is first inserted into the slot 204 of the first support connector 2. Fig.13 , the insert plate 116 is embedded in the second groove of the first supporting connector 2, and the lower surface of the force plate 114 is placed on the upper surface of the bottom block 206. Then the first supporting connector 2 and the second supporting connector 11 are placed on the square steel beam 1, and then the first locking bolt 405 is used to pass through the hole on the top of the square steel beam 1 and the round hole on the force plate 114 in sequence, and finally the first locking nut 406 is screwed on and tightened, and the force plate 114 is subjected to downward pressure, thereby giving downward pressure to the first supporting connector 2 and the second supporting connector 11 together, so as to fix the first supporting connector 2 and the second supporting connector 11 on the square steel beam 1 at the same time.

[0085] In addition, a plurality of first locking bolts 405 and first locking nuts 406 may be used to fix the load-bearing plate 114 .

[0086] Optionally, in order to improve the strength of the load-bearing plate 114, as Fig.10 , the left side of the force-bearing plate 114 is in a triangular shape.

[0087] In this embodiment, the second bottom plate 111 , the second supporting plate 112 , the second sliding block 113 , the force-bearing plate 114 , and the inserting plate 116 are integrally formed metal plates.

[0088] Optionally, a plurality of reinforcing ribs 210 are welded on the first supporting connector 2, and the reinforcing ribs 210 are fixed between the first supporting plate 202 and the first bottom plate 201. Similarly, a reinforcing plate 115 for improving strength is also welded between the second supporting plate 112 and the second bottom plate 111 of the second supporting connector 11. The reinforcing plate 115 and the reinforcing ribs 210 are any one of a right-angled triangular plate, a right-angled trapezoidal plate or a rectangular plate.
