Technical Field

[0001] This application relates to the field of photovoltaic module installation technology, and in particular to a photovoltaic module installation structure and a photovoltaic module. Background Technology

[0002] Existing photovoltaic panels are usually fixed to photovoltaic brackets with external bolts and nuts, such as U-bolts, which are used with nuts to fix the photovoltaic panels to the photovoltaic brackets. When photovoltaic panels are installed in an external environment, the external bolts are prone to rust, which makes disassembly difficult during later maintenance, seriously affecting the efficiency of photovoltaic panel disassembly and replacement, and increasing maintenance costs and time costs.

[0003] Therefore, given the aforementioned background technology, how to improve the efficiency of photovoltaic panel disassembly and replacement is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] The mounting block has a first end that engages with the mounting slider for limiting, and a second end that is spaced apart from the main body of the support frame to form a receiving space for clamping the photovoltaic panel.

[0008] A bolt is located between the first end and the second end, and passes through the mounting clip and the mounting slider in sequence;

[0009] A limiting retaining ring is sleeved on the shank of the bolt and abuts against the lower end face of the mounting slider. The limiting retaining ring includes a movable telescopic part, which is axially engaged with the thread of the shank in a first position and axially disengaged from the thread of the shank in a second position.

[0010] Preferably, the telescopic part has a locking part at one end facing the rod. In the first position, the locking part extends between adjacent threads of the rod and is axially locked with the threads. In the second position, the locking part disengages from the adjacent threads of the rod.

[0012] The retaining ring body is sleeved on the outer periphery of the rod, and through grooves are provided on the opposite side walls of the retaining ring body for the telescopic part to move. The telescopic part is provided in each through groove.

[0013] The drive unit is rotatably located at the other end of the telescopic part and outside the retaining ring body;

[0014] A support portion is provided on the outer surface of the two side walls of the retaining ring body having the through groove. The end of the support portion away from the retaining ring body abuts against the middle of the driving portion, so that the driving portion rotates around the abutment position as the axis and drives the telescopic portion to move to the first position or the second position.

[0015] Preferably, the telescopic part is provided with a limiting baffle, and a first elastic element is provided between the limiting baffle and the side wall of the retaining ring body. The first elastic element is used to provide the telescopic part with an elastic force facing the rod.

The upper surface of the upper wing plate is provided with a limiting groove, the first end of which is inserted into the limiting groove, and the limiting retaining ring abuts against the lower surface of the lower wing plate.

[0017] Preferably, the mounting block further includes a connecting end connecting the first end and the second end. The connecting end includes a first connecting end parallel to the mounting slider. The first connecting end and the mounting slider are provided with threaded holes for threaded connection with the bolt. The head of the bolt abuts against the upper surface of the first connecting end.

[0018] Preferably, the connecting end further includes a second connecting end parallel to the side wall of the photovoltaic panel. The second connecting end has a built-in groove on its end face facing the photovoltaic panel. An auxiliary pressing block moves within the built-in groove. A second elastic element is provided between the auxiliary pressing block and the groove wall of the built-in groove.

[0022] Compared to the aforementioned background technology, the mounting slider of this application is movably engaged with the main body of the support frame, and the mounting block is also engaged with the mounting slider in a limiting engagement. When the photovoltaic panel is pressed onto the main body of the support frame, the mounting block and the mounting slider can be connected by bolts. At this time, the traditional fixing nut is replaced by a limiting retaining ring fitted onto the shank of the bolt. The limiting retaining ring abuts against the lower end of the mounting slider. After the bolt is assembled in place, the telescopic part of the limiting retaining ring can move to the first position, and the telescopic part is axially engaged with the thread of the shank.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, a photovoltaic module mounting structure is provided. This mounting structure includes a mounting slider 2, a mounting block 3, bolts 6, and a limiting retaining ring 5. The mounting slider 2 is mounted on the support frame body 1 and is movably engaged with it. Therefore, the position of the mounting slider 2 on the support frame body 1 can be adjusted according to the actual installation position of the photovoltaic panel 4. Further, the upper end of the mounting slider 2 is located outside the support frame body 1 to facilitate the installation of the mounting block 3 at the upper end of the mounting slider 2. Specifically, the first end 31 of the mounting block 3 is engaged with the mounting slider 2, while the second end 34 of the mounting block 3 is spaced apart from the upper surface of the support frame body 1, thus forming a receiving space for clamping the photovoltaic panel 4. When the photovoltaic panel 4 is placed in this receiving space, it can be assembled into the receiving space by the compression of the second end 34 of the mounting block 3. The photovoltaic panel 4 is an existing structure and will not be described in detail here.

[0038] Bolt 6 is located between the first end 31 and the second end 34 of mounting block 3. The shank 61 of bolt 6 passes through mounting block 3 and mounting slider 2 in sequence. When bolt 6 gradually locks mounting block 3 and mounting slider 2, the first end 31 of mounting block 3 is engaged with mounting slider 2, and the locking position of bolt 6 is located between the first end 31 and the second end 34. Therefore, the second end 34 of mounting block 3 will generate a squeezing force that squeezes the upper wall of the outer edge of photovoltaic panel 4, thereby pressing photovoltaic panel 4 into the accommodating space formed by the second end 34 and the support frame body 1.

[0039] To facilitate the quick locking or loosening of the mounting block 3 and mounting slider 2 by the bolt 6, a limiting ring 5 is fitted onto the rod 61 of the bolt 6, and the limiting ring 5 can abut against the lower end face of the mounting slider 2. The limiting ring 5 includes a movable telescopic part 52. When the bolt 6 is installed in place, the telescopic part 52 can move to the first position, and the telescopic part 52 can be axially engaged with the thread of the rod 61. This, combined with the abutment effect between the limiting ring 5 and the lower end face of the mounting slider 2, can quickly limit and fix the bolt 6, preventing it from being loosened and thus avoiding displacement and loosening of the bolt 6. When the telescopic part 52 moves to the second position, the axial engagement between the telescopic part 52 and the thread of the rod 61 is released. At this time, the bolt 6 can be turned to quickly loosen the mounting block 3 and mounting slider 2, realizing the rapid disassembly of the photovoltaic panel 4.

[0040] It should be noted that during the process of the telescopic part 52 moving from the first position to the second position, the telescopic part 52 will gradually move away from the rod part 61; conversely, during the process of the telescopic part 52 moving from the second position to the first position, the telescopic part 52 will gradually move closer to the rod part 61.

[0041] In summary, the mounting slider 2 of this application is movably engaged with the support frame body 1, and the mounting block 3 is also engaged with the mounting slider 2 in a limiting manner. When the photovoltaic panel 4 is pressed onto the support frame body 1, the mounting block 3 and the mounting slider 2 can be connected by bolts 6. At this time, the traditional fixing nut is replaced by a limiting ring 5, which is sleeved on the rod 61 of the bolt 6. The limiting ring 5 abuts against the lower end of the mounting slider 2. After the bolt 6 is assembled in place, the telescopic part 52 of the limiting ring 5 can move to the first position, and the telescopic part 52 is axially engaged with the thread of the rod 61. At this time, the limiting ring 5 can quickly limit and fix the bolt 6, preventing the bolt 6 from shifting and loosening. When it is necessary to remove the photovoltaic panel 4, the telescopic part 52 moves to the second position, and the thread of the telescopic part 52 is released from the axial engagement with the rod 61, so that the bolt 6 can be quickly removed. In the above manner, the photovoltaic panel 4 can be quickly disassembled and installed with the cooperation of the bolt 6 and the limiting ring 5, thereby improving the efficiency of disassembling and replacing the photovoltaic panel 4 itself.

[0042] A locking part is provided at the end of the telescopic part 52 facing the rod part 61. When the telescopic part 52 is in the first position, the locking part can extend between two adjacent threads of the rod part 61, thereby axially engaging the locking part with the threads. When the locking part is in the second position, the locking part can disengage from the two adjacent threads of the rod part 61, thereby loosening the bolt 6. The telescopic part 52 can be a telescopic rod or a telescopic block, and the locking part can be an arc-shaped wall surface formed at the end of the telescopic part 52.

[0043] Please refer to Figure 3 and Figure 4 The limiting retaining ring 5 also includes a retaining ring body 51, a driving part 53, and a supporting part 54. The retaining ring body 51 is a hollow block structure. The retaining ring body 51 is sleeved on the outer periphery of the rod part 61 and abuts against the lower end face of the mounting slider 2. Through slots 58 are provided on the opposite side walls of the retaining ring body 51 for the telescopic part 52 to move. That is, each through slot 58 is provided with a corresponding telescopic part 52. The two telescopic parts 52 are engaged with the thread of the rod part 61, making the engagement effect more stable and reliable. The through slot 58 can be a square slot or a round slot, and the corresponding telescopic part 52 should be a square rod or a round rod. However, considering that the telescopic part 52 should avoid rotation, the through slot 58 is preferably a square slot.

[0044] The drive unit 53 is rotatably disposed at the other end of the telescopic unit 52 and located on the outside of the retaining ring body 51. The support unit 54 is disposed on the outer surface of the two side walls of the retaining ring body 51 having the through groove 58. Please refer to [reference needed]. Figure 4 The end of the support part 54 away from the retaining ring body 51 slides against the middle of the drive part 53, so that when the drive part 53 is rotated under force, it can rotate around the position abutting the support part 54 as the axis, thereby driving the telescopic part 52 to move to the first position or the second position; furthermore, the drive part 53 can be connected to the telescopic part 52 through the hinge 57. The drive part 53 can be a drive rod or a drive block, and the support part 54 can be a support plate or a support rod, which will not be described in detail here.

[0045] It should be noted that there are many ways to make the drive unit 53 rotate under force, such as using electric drive to make the drive unit 53 rotate, using a power cylinder to make the drive unit 53 rotate, or using manual pressing to make the drive unit 53 rotate. These will not be described in detail here, but all fall within the scope of protection of this application.

[0046] Furthermore, a limiting baffle 55 is provided on the telescopic part 52, and a first elastic element 56 is provided between the limiting baffle 55 and the side wall of the retaining ring body 51. The first elastic element 56 can provide elastic force for the telescopic part 52 to move towards the rod part 61; that is, when the drive part 53 is rotated by manual pressing, pressing the drive part 53 can make the telescopic part 52 reach the second position, and under the action of the first elastic element 56, when the external pressing force is removed, the first elastic element 56 can make the telescopic part 52 automatically return to the first position, realizing the automatic thread limiting and locking engagement between the telescopic part 52 and the rod part 61. The first elastic element 56 can be a tension spring.

[0047] Further, please refer to Figure 4 The limiting baffle 55 can be located inside the retaining ring body 51, and the corresponding first elastic member 56 is disposed between the limiting baffle 55 and the inner side wall of the retaining ring body 51. The first elastic member 56 has an initial tension amount; the limiting baffle 55 can also be located outside the retaining ring body 51, and the first elastic member 56 is disposed between the limiting baffle 55 and the outer side wall of the retaining ring body 51. The first elastic member 56 has an initial compression amount.

[0048] In addition, please refer to Figure 3 The mounting slider 2 has an I-shaped cross-section. The upper wing plate 21 and lower wing plate 22 of the I-shape can clamp the mounting position of the support frame body 1, thereby allowing the mounting slider 2 to be stably set in the mounting position of the support frame body 1. A limiting groove 211 is provided on the upper surface of the upper wing plate 21. The limiting groove 211 can be a rectangular groove. The first end 31 of the mounting block 3 can be inserted into the limiting groove 211 and movably engaged with the limiting groove 211. The limiting retaining ring 5 abuts against the lower surface of the lower wing plate 22. Specifically, the upper end face of the retaining ring body 51 abuts against the lower surface of the lower wing plate 22.

[0049] Please refer to Figure 3 The mounting block 3 also includes a connecting end that connects the first end 31 and the second end 34. The connecting end, the first end 31, and the second end 34 are an integral structure. In this embodiment, the connecting end includes a first connecting end 32 parallel to the mounting slider 2. The first connecting end 32 and the mounting slider 2 are provided with threaded holes for threaded connection with the bolt 6. The head of the bolt 6 abuts against the upper surface of the first connecting end 32. That is, the positions of the threaded holes on the first connecting end 32 and the mounting slider 2 correspond, and the mounting block 3 and the mounting slider 2 are connected together through the cooperation of the bolt 6 and the threaded holes.

[0050] In addition, the connection end also includes a second connection end 33 parallel to the sidewall of the photovoltaic panel 4, please refer to Figure 3The first connecting end 32 has a built-in groove 331 on its end face facing the photovoltaic panel 4. A movable auxiliary pressing block 332 is provided within the built-in groove 331. A second elastic element 333 is provided between the auxiliary pressing block 332 and the groove wall of the built-in groove 331. The second elastic element 333 provides elastic force to the auxiliary pressing block 332 to support its movement towards the photovoltaic panel 4. The built-in groove 331 can be a circular groove. When the second connecting end 33 is in contact with the side wall of the photovoltaic panel 4, the auxiliary pressing block 332 can press against the photovoltaic panel 4 using the elastic force of the second elastic element 333, thereby improving the stability between the mounting block 3 and the photovoltaic panel 4. The second elastic element can also be a tension spring.

[0051] In some embodiments, the second end 34 may abut against the upper wall of the outer edge of the photovoltaic panel 4, please refer to Figure 1 A number of limiting holes 41 are provided on the upper wall of the outer edge of the photovoltaic panel 4. The end face of the second end 34 facing the photovoltaic panel 4 is provided with a locking rod 341 that is inserted into the limiting holes 41. When installing the photovoltaic panel 4, the locking rod 341 can be inserted into the limiting holes 41 first, and the photovoltaic panel 4 can be easily fixed. At this time, the photovoltaic panel 4 does not need to be moved manually, thereby reducing the fatigue of the installer. Then, the second end 34 can be pressed against the upper wall of the outer edge of the photovoltaic panel 4 by tightening the bolt 6. After the bolt 6 is tightened, the limiting ring 5 can be locked into the rod 61 of the bolt 6 to prevent the bolt 6 from loosening.

[0052] In addition, several elastic pads 342 are fixed on the outer circumferential surface of the locking rod 341, please refer to... Figure 3 After the locking rod 341 is inserted into the limiting locking hole 41, the elastic locking pad 342 can be interference-fitted with the limiting locking hole 41, thereby improving the positioning effect of the locking rod 341 on the photovoltaic panel 4.

[0053] This application also provides a photovoltaic module, which includes a photovoltaic panel 4, a support frame body 1, and a photovoltaic module mounting structure as described above. Therefore, this photovoltaic module also has all the advantages of the photovoltaic module mounting structure.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0055] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
