Description

Technical Field

[0001] This application relates to the field of photovoltaic module installation technology, and in particular to a photovoltaic module mounting plate with adjustable length and a photovoltaic module. Background Technology

[0002] When conventional pressure plates are used for installation of photovoltaic (PV) modules in existing power plants, the gap between the PV modules is 6mm. The PV modules are pressed onto the crossbeam by the pressure plates. However, when a slanted beam is located directly below the gap between the PV modules, the U-bolts and washers will interfere with the slanted beam, making installation impossible. In this situation, the only options are to rearrange the PV modules or move them to make room for the slanted beam. This approach leaves a large gap, leading to an unsightly appearance and exacerbating water and rain leaks, among other adverse effects.

[0003] Therefore, how to prevent interference between the inclined beam and the pad is a technical problem that needs to be solved by those skilled in the art, given the above background technology. Utility Model Content

[0004] The purpose of this application is to provide a photovoltaic module mounting plate and a photovoltaic module with adjustable length. By adjusting the length of the mounting plate, the installation position of the locking member relative to the crossbeam can be changed, thereby avoiding interference between the locking member and the inclined beam.

[0005] To achieve the above objectives, this application provides a photovoltaic module mounting plate with adjustable length, comprising:

[0006] A pressure tongue is provided on the crossbeam. The first end of the pressure tongue presses the component frame tightly against the crossbeam, and the second end extends along the length direction of the crossbeam. A plurality of limiting protrusions distributed along the length direction are provided at the second end.

[0007] A pressure plate chamber is clamped at the second end, and a plurality of limiting slots are provided at the clamping end of the pressure plate chamber along the length direction. The limiting slots and the limiting protrusions are engaged in a limiting engagement in the length direction.

[0008] The locking component includes a U-bolt, a washer, and a nut. The U-shaped portion of the U-bolt fits onto the pressure plate chamber and the crossbeam. The thread of the U-bolt passes through the washer. The nut is screwed onto the thread and presses the washer against the crossbeam, thereby locking the pressure plate chamber onto the crossbeam.

[0009] Preferably, the limiting protrusion can engage with different limiting slots to change the relative position of the pressure tongue and the pressure plate chamber in the length direction.

[0010] Preferably, the tongue has a reserved groove in the middle, and the opening of the reserved groove faces the crossbeam so that the water tank wall on the crossbeam enters the reserved groove.

[0011] Preferably, the limiting groove is a through groove extending in a horizontal direction, the horizontal direction being perpendicular to the length direction, and the limiting protrusion slides out of or into the limiting groove along the horizontal direction.

[0012] Preferably, the clamping end of the pressure plate chamber is provided with the limiting slots on both clamping surfaces, and the second end is provided with a clamping block. The limiting protrusions are provided on the upper and lower sides of the clamping block so that the limiting protrusions on the upper and lower sides of the clamping block respectively cooperate with the limiting slots on the two clamping surfaces.

[0013] Preferably, the second end is further provided with a reinforcing pad that fits against the crossbeam, and there is a gap between the reinforcing pad and the clamping block.

[0014] Preferably, the gap has an opening on the side facing the pressure chamber, and one of the clamping surfaces extends into the gap.

[0015] Preferably, the pressure plate chamber is provided with a fixing groove that mates with the U-bolt, and the U-shaped bottom of the U-shaped portion is embedded in the fixing groove.

[0016] Preferably, the end of the pressure plate compartment away from the clamping end is provided with a balancing pad that abuts against the crossbeam, so that the pressure plate compartment is parallel to the crossbeam.

[0017] A photovoltaic module, comprising:

[0018] beam;

[0019] A component frame is provided on the crossbeam, and the component frame is provided with an extension extending along the length direction of the crossbeam;

[0020] Photovoltaic panels are fixed to the frame of the component;

[0021] Mounting plate, such as the photovoltaic module mounting plate with adjustable length as described above, wherein the pressure tongue of the mounting plate presses against the extension to press the module frame against the crossbeam.

[0022] Compared to the aforementioned background technology, the mounting plate of this application includes a pressure tongue and a pressure plate chamber. The pressure plate chamber can clamp or engage with the second end of the pressure tongue, thus allowing the pressure tongue and pressure plate chamber to be considered as a single structure. The pressure plate chamber is locked onto the crossbeam by a locking member, thereby pressing the first end of the pressure tongue against the crossbeam. Furthermore, the second end of the pressure tongue is provided with multiple limiting protrusions, and the clamping end of the pressure plate chamber has multiple limiting slots. Through the cooperation of the limiting protrusions and the limiting slots, the pressure tongue and pressure plate chamber are stably engaged along the length of the crossbeam. Moreover, by cooperating with the limiting protrusions and different limiting slots, the overall length of the pressure tongue and pressure plate chamber can be changed, thereby adaptively changing the locking position of the locking member on the pressure plate chamber, thus avoiding the interference between the pad and the inclined beam caused by the inability to adjust the length of the existing pressure plate.

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.

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.

[0034] 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.

[0035] like Figure 1 As shown, in this embodiment, a photovoltaic module mounting plate with adjustable length is provided. The mounting plate includes a pressure tongue 5, a pressure plate compartment 6, and a locking member 7. The pressure tongue 5 is provided on the crossbeam 3, and the module frame 2 can be pressed tightly onto the crossbeam 3 by the pressure tongue 5. The photovoltaic panel 1 is fixedly provided on the module frame 2, thereby fixing the photovoltaic panel 1 to the crossbeam 3.

[0036] Specifically, the first end of the pressure tongue 5 presses against the extension 21 of the component frame 2, which extends along the length of the crossbeam 3. The first end of the pressure tongue 5 presses the extension 21 against the crossbeam 3, thereby locking the entire component frame 2 onto the crossbeam 3. The second end of the pressure tongue 5 extends along the length of the crossbeam 3 and is located away from the extension 21 of the frame component. Multiple limiting protrusions 511 distributed along the length of the crossbeam 3 are provided at the second end of the pressure tongue 5.

[0037] The pressure plate chamber 6 can be clamped at the second end of the pressure tongue 5, and multiple limiting slots 63 distributed along the length of the crossbeam 3 are provided at the clamping end of the pressure plate chamber 6; please refer to Figure 2 When the pressure plate compartment 6 is clamped at the second end of the pressure tongue 5, the limiting protrusion 511 can be engaged in the limiting groove, so that the limiting groove 63 and the limiting protrusion 511 are engaged in the upper limit in the length direction of the crossbeam 3.

[0038] Since both the limiting protrusion 511 and the limiting slot 63 are distributed along the length of the crossbeam 3, and there are multiple of both, the limiting protrusion 511 can be selected to be engaged in different limiting slots 63 according to the actual situation. This changes the relative position of the pressure tongue 5 and the pressure plate chamber 6 along the length of the crossbeam 3, thereby changing the overall length of the pressure tongue 5 and the pressure plate chamber 6. Please refer to... Figure 1 , Figure 1 The limiting protrusion 511 of the pressure tongue 5 engages with the limiting slot 63 at the front end of the pressure chamber 6. At this time, the overall length of the pressure tongue 5 and the pressure chamber 6 is relatively long; please refer to... Figure 2 , Figure 2 The limiting protrusion 511 of the middle pressure tongue 5 engages with the limiting slot 63 at the rear end of the pressure plate chamber 6. At this time, the overall length of the pressure tongue 5 and the pressure plate chamber 6 is relatively short.

[0039] It should be noted that when installing two adjacent photovoltaic panels 1, one of the module frames 2 can be installed and fixed using the mounting plate, while the other module frame 2 can use either a regular mounting plate or the mounting plate of this application; no further restrictions are imposed here. When using a regular mounting plate to install and fix one of the module frames 2, please refer to... Figure 1 The left component frame 2 is fixed to the measuring plate using a common pressure plate, and the right component frame 2 is fixed using the mounting pressure plate of this application. Therefore, the mounting pressure plate of the right component frame 2 has an adjustable length function. Only by adjusting the length of the mounting pressure plate can interference between the locking part 7 of the mounting pressure plate and the locking part 7 of the common pressure plate and the inclined beam 4 be avoided. The locking part 7 of the common pressure plate can refer to the locking part 7 of this application.

[0040] After the overall length of the pressure tongue 5 and the pressure plate chamber 6 changes, the position of the locking element 7 used to lock the pressure plate chamber 6 and the crossbeam 3 will also change. Therefore, when the inclined beam 4 affects the installation position of the U-bolt 71 or the pad 72, the overall length of the pressure tongue 5 and the pressure plate chamber 6 can be increased by changing the engagement position of the limiting protrusion 511 and the limiting slot 63, so that the locking element 7 can be installed without the position of the inclined beam 4.

[0041] Furthermore, the locking component 7 includes a U-bolt 71, a washer 72, and a nut 73. The U-shaped portion of the U-bolt 71 fits onto the pressure chamber 6 and the crossbeam 3. The thread of the U-bolt 71 passes through the washer 72. The nut 73 is screwed onto the thread and presses the washer 72 against the crossbeam 3, thereby locking the pressure chamber 6 onto the crossbeam 3. A fixing groove 61 that mates with the U-bolt 71 can be provided on the pressure chamber 6. The U-shaped bottom of the U-shaped portion can be embedded in the fixing groove 61, thus limiting the position of the pressure chamber 6. Simultaneously, with the U-bolt 71 fixed to the crossbeam 3 by the washer 72 and the nut 73, the pressure chamber 6 is further locked onto the crossbeam 3. The locking of the pressure chamber 6 to the crossbeam 3 also fixes the pressure tongue 5 to the crossbeam 3, providing a stable pressing effect on the frame assembly. When the lengths of the pressure tongue 5 and the pressure plate chamber 6 change, the position of the pressure tongue 5 relative to the crossbeam 3 remains unchanged, which will cause the position of the pressure plate chamber 6 to change, thereby changing the position of the locking part 7 relative to the crossbeam 3. This allows for easy adjustment of the position of the locking part 7 and avoids interference between the locking part 7 and the inclined beam 4.

[0042] In summary, the mounting plate of this application includes a pressure tongue 5 and a pressure plate compartment 6. The pressure plate compartment 6 can clamp or engage with the second end of the pressure tongue 5, so that the pressure tongue 5 and the pressure plate compartment 6 can be regarded as an integral structure. The pressure plate compartment 6 is locked onto the crossbeam 3 by the locking member 7, so that the first end of the pressure tongue 5 presses the frame assembly onto the crossbeam 3. Furthermore, the second end of the pressure tongue 5 is provided with multiple limiting protrusions 511, and the clamping end of the pressure plate compartment 6 is provided with multiple limiting slots 63. Through the cooperation of the limiting protrusions 511 and the limiting slots 63, the pressure tongue 5 and the pressure plate compartment 6 are stably engaged in the length direction of the crossbeam 3. Furthermore, through the cooperation of the limiting protrusions 511 and different limiting slots 63, the overall length of the pressure tongue 5 and the pressure plate compartment 6 can be changed, thereby adaptively changing the locking position of the locking member 7 on the pressure plate compartment 6, thereby avoiding the situation where the position of the pad 72 and the inclined beam 4 is interfered due to the inability to adjust the length of the existing pressure plate.

[0043] In some embodiments, a reserved groove 53 is provided in the middle of the pressure tongue 5, and the opening direction of the reserved groove 53 is towards the measuring device. For photovoltaic power stations that need to install water tanks 8, please refer to... Figure 3 The water tank 8 is installed on the lower side of the component frame 2 and the upper side of the crossbeam 3. The wall of the water tank 8 can correspond to the position of the reserved groove 53, so that the wall of the water tank 8 enters the reserved groove 53, thereby avoiding the presence of the water tank 8 from affecting the normal installation of the mounting plate.

[0044] Furthermore, the limiting slot 63 of this application is a through slot extending in a horizontal direction, which can be perpendicular to the length direction of the crossbeam 3. Figure 1 and Figure 3In terms of horizontal direction, the pressure plate compartment 6 is in the front-to-back direction. The limiting protrusion 511 can slide out or slide into the limiting slot 63 in the horizontal direction. Specifically, when installing the photovoltaic panel 1, if it is necessary to change the length of the installation pressure plate, the pressure tongue 5 can be slid out from the front or rear side of the pressure plate compartment 6, that is, the limiting protrusion 511 can be slid out from the front or rear side of the limiting slot 63. After adjusting the length, the pressure plate compartment 6 can be reinstalled from the front or rear side of the limiting slot 63. The detachable connection between the pressure tongue 5 and the pressure plate compartment 6 improves the flexibility of the installation pressure plate and makes it more convenient and faster to use.

[0045] To improve the engagement between the pressure tongue 5 and the pressure chamber 6, limiting grooves 63 are provided on both clamping surfaces at the clamping end of the pressure chamber 6. Please refer to... Figure 2 The second end of the pressure tongue 5 is provided with a clamping block 51. The upper and lower sides of the clamping block 51 are provided with limiting protrusions 511. The clamping end of the pressure plate chamber 6 can be clamped on the clamping block 51. At the same time, the limiting slots 63 on the two clamping surfaces can respectively engage with the limiting protrusions 511 on the upper and lower sides of the clamping block 51, so that the pressure plate chamber 6 and the pressure tongue 5 form a whole after being engaged, ensuring the pressing effect of the pressure tongue 5 on the frame assembly.

[0046] At the second end of the pressure tongue 5, there is also a reinforcing pad 52 that fits against the crossbeam 3. Please refer to [reference needed]. Figure 1 The clamping pad 52 and the crossbeam 3 have a stable and frictional contact surface, which makes the reinforcing pad 52 more stable relative to the crossbeam 3. At the same time, the reinforcing pad 52 also provides some support for the pressure tongue 5. When the pressure chamber 6 is locked onto the crossbeam 3, this support makes the locking effect of the pressure chamber 6 more stable. Furthermore, there is a gap between the reinforcing pad 52 and the clamping block 51. The gap has an opening on the side facing the pressure chamber 6. One clamping surface of the pressure chamber 6 can extend into the gap, and after one clamping surface of the pressure chamber 6 extends into the gap, it can abut against the upper side of the reinforcing pad 52. Thus, when the pressure chamber 6 is locked to the crossbeam 3, the locking force is directly transmitted to the crossbeam 3 through the clamping surface and the reinforcing pad 52, so that sufficient friction is generated between the reinforcing pad 52 and the crossbeam 3, thereby preventing the pressure tongue 5 from being displaced when the frame assembly is under load.

[0047] In addition, a balance pad 62 is provided on the side of the pressure chamber 6 away from its clamping end, which abuts against the crossbeam 3. The balance pad 62 and the crossbeam 3 have a stable contact surface, so that the pressure chamber 6 can be parallel to the crossbeam 3 as a whole. After the pressure chamber 6 and the crossbeam 3 are locked, the force on the pressure chamber 6 can be perpendicular to the crossbeam 3, ensuring that the pressure chamber 6 and the crossbeam 3 have a stable locking effect.

[0048] This application also provides a photovoltaic module, which includes a crossbeam 3, a module frame 2, a photovoltaic panel 1, and a mounting plate. The module frame 2 is disposed on the crossbeam 3, and the module frame 2 is provided with an extension 21 extending along the length direction of the crossbeam 3. The photovoltaic panel 1 is fixed on the module frame 2. The mounting plate is the adjustable-length photovoltaic module mounting plate of this application. The pressure tongue 5 of the mounting plate presses against the extension 21 to press the module frame 2 against the crossbeam 3. Therefore, this photovoltaic module also has all the advantages of the adjustable-length photovoltaic module mounting plate.

[0049] 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.

[0050] 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.
