Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic device. Background Technology

[0002] Photovoltaic (PV) installations typically generate electricity by mounting solar photovoltaic (PV) modules on a frame and placing them in a sunny location to receive sunlight. To increase power generation, a large area of ​​PV modules often needs to be installed. However, for ease of transportation, existing PV installations usually involve transporting the mounting frame and PV modules to the site first, followed by on-site assembly, a relatively cumbersome process. Utility Model Content

[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0060] In the description of this utility model, it should be understood that the use of terms such as "first" and "second" to define the components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0061] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0062] like Figures 1 to 10 As shown, the photovoltaic device in this embodiment includes a photovoltaic component having a first state and a second state. The photovoltaic component can switch between the first state and the second state. The photovoltaic component includes a first photovoltaic module 1 and a second photovoltaic module 2.

[0063] The first photovoltaic module 1 includes a first mounting frame 11, a solar photovoltaic panel 100 located on the first mounting frame 11, and a first connection structure 12 disposed on the first mounting frame 11;

[0064] The second photovoltaic module 2 includes a second mounting frame 21, a solar photovoltaic panel 100 located on the second mounting frame 21, and a second connecting structure 22 disposed on the second mounting frame 21 and slidably engaged with the first connecting structure 12. Through the sliding engagement of the first connecting structure 12 and the second connecting structure 22, the first mounting frame 11 can drive the first photovoltaic module 1 to slide relative to the second mounting frame 21 and the second photovoltaic module 2.

[0065] In the first state, such as Figures 4 to 10As shown, the first mounting bracket 11 is located above the second mounting bracket 21 and folded relative to the second mounting bracket 21. In this application, the second mounting bracket 21 is positioned above the photovoltaic component on a horizontal surface, with the second mounting bracket 21 also positioned on a horizontal surface. At this time, the solar photovoltaic panel 100 on the second mounting bracket 21 is also in a state perpendicular or approximately perpendicular to the vertical direction. The first mounting bracket 11 is located above the second mounting bracket 21, that is, the first mounting bracket 11 is vertically above the second mounting bracket 21. Simultaneously, the projections of the first mounting bracket 11 and the second mounting bracket 21 on the horizontal plane completely overlap or at least partially overlap. Figures 4 to 10 As shown, the first state of the photovoltaic components is that the first photovoltaic module 1 and the second photovoltaic module 2 are folded together.

[0066] In the second state, such as Figures 1 to 3As shown, the first mounting bracket 11 is located to the side of the second mounting bracket 21 and unfolds relative to the second mounting bracket 21. In the second state, the height of the first mounting bracket 11 relative to the second mounting bracket 21 is less than its height relative to the second mounting bracket 21 in the first state. In this application, the "side" of the second mounting bracket 21 is defined with the photovoltaic component placed on a horizontal surface and the second mounting bracket 21 placed on the horizontal surface as a reference. At this time, the bottom surface of the second mounting bracket 21 is in contact with the horizontal surface, and the side of the second mounting bracket 21 is also along the horizontal surface away from the center of the second mounting bracket 21. The solar photovoltaic panel 100 located on the second mounting bracket 21 is also in a state that is perpendicular or approximately perpendicular to the vertical direction. The height direction of the second mounting bracket 21 is the direction in which the second mounting bracket 21 rises vertically. The fact that the height of the first mounting bracket 11 relative to the second mounting bracket 21 in the second state is less than its height relative to the second mounting bracket 21 in the first state means that when the second mounting bracket 21 is placed on the horizontal surface, the height of the first mounting bracket 11 relative to the ground is smaller in the second state than in the first state. The switching between the first and second states is achieved by sliding the first mounting bracket 11 relative to the second mounting bracket 21 and moving it along the height direction of the second mounting bracket 21. That is, with the second mounting bracket 21 placed on a horizontal surface as a reference, the solar photovoltaic panel 100 on the second mounting bracket 21 is also in a state perpendicular or approximately perpendicular to the vertical direction. The sliding connection structure 12 and the second connection structure 22 of this application can not only slide relative to each other in the horizontal direction but also move relative to each other in the vertical direction. This allows the first mounting bracket 11 to slide relative to the second mounting bracket 21 in the horizontal direction and move it along the height direction, ultimately enabling the photovoltaic component to switch from the first state to the second state, and vice versa. The photovoltaic component in this embodiment includes a first photovoltaic module 1 and a second photovoltaic module 2. In the second state, in addition to being able to unfold relative to each other in the horizontal direction and having a larger overall size in the horizontal direction to increase the area exposed to sunlight, it can also reduce the overall size of the vertical structure in the first state, further aligning the first photovoltaic module 1 and the second photovoltaic module 2 in the height direction.

[0067] The photovoltaic device of this embodiment has a first state and a second state by providing a sliding connection structure 12 and a second connection structure 22 between adjacent first photovoltaic modules 1 and second photovoltaic modules 2. During transportation, the photovoltaic device can be switched to the first state where the first mounting frame 11 and the second mounting frame 21 are folded. In this state, the photovoltaic device is compact and easy to transport. During installation, the first mounting frame 11 and the second mounting frame 21 slide relative to each other, and the first mounting frame 11 moves along the height direction of the second mounting frame 21, allowing the first photovoltaic module 1 and the second photovoltaic module 2 to be unfolded and aligned, thus facilitating installation.

[0068] In some embodiments, such as Figure 3 , Figures 6 to 10 As shown, the first connecting structure 12 includes a first strip groove 121 disposed on the first mounting bracket 11, and the second connecting structure 22 includes a second strip groove 221 disposed on the second mounting bracket 21 and a sliding member 222. In the embodiment shown, both the first strip groove 121 and the second strip groove 221 are straight strip grooves. The sliding member 222 includes a first end and a second end. The first end of the sliding member 222 is slidably engaged with the first strip groove 121 and can rotate relative to the first strip groove 121, and the second end of the sliding member 222 is slidably engaged with the second strip groove 221 and can rotate relative to the second strip groove 221. In this embodiment, the sliding of the first mounting bracket 11 relative to the second mounting bracket 21 can be achieved through the sliding engagement of the first end of the sliding member 222 with the first strip groove 121. By rotating the first end of the slider 222 with the first strip groove 121 and rotating the second end of the slider 222 with the second strip groove 221, the first mounting bracket 11 can move along the height direction of the second mounting bracket 21. For example, the photovoltaic component can move from... Figure 6 The first state shown has switched to Figure 1 In the second state shown, with the second mounting bracket 21 placed on a horizontal surface as a reference, the solar photovoltaic panel 100 on the second mounting bracket 21 is in a state perpendicular or approximately perpendicular to the vertical direction. First, the sliding of the second end of the sliding member 222 relative to the second strip groove 221 causes the first mounting bracket 11 to slide horizontally relative to the second mounting bracket 21. When the sliding reaches a point where the second end of the sliding member 222 can no longer slide relative to the second strip groove 221 and the first end of the sliding member 222 can no longer slide relative to the first strip groove 121, the first end of the sliding member 222 rotates relative to the second end. That is, the first end of the sliding member 222 rotates relative to the first strip groove 121, and the second end of the sliding member 222 rotates relative to the second strip groove 221. At this point, the first mounting bracket 11 can move along the height direction of the second mounting bracket 21 (at this time, the first mounting bracket 11 will also further extend horizontally relative to the second mounting bracket 21), thereby achieving the switch from the first state to the second state. This embodiment can achieve an effective and reliable switch between the first and second states of the photovoltaic component.

[0069] In some embodiments, such as Figure 6 , Figures 8-10 and Figure 13As shown, the slider 222 includes a slider 2221 and pulleys 2222 mounted on the slider 2221, which respectively slide in cooperation with the first strip groove 121 and the second strip groove 221. In the embodiment shown, the slider 2221 includes an end plate, two connecting shafts at both ends of the end plate, bushings respectively mounted on the two connecting shafts, bearings mounted on the bushings, bearing retaining rings for limiting the axial displacement of the bearings on the connecting shafts, and wheel bodies disposed on the outer rings of the bearings. In this embodiment, by the rolling of the pulleys 2222 within the first strip groove 121 and the second strip groove 221, the slider 222 can smoothly slide relative to the first strip groove 121 and the second strip groove 221. At the same time, when the end of the slider 222 needs to rotate relative to the first strip groove 121 and the second strip groove 221, the arrangement of the pulleys 2222 also makes the rotation easier to achieve, thereby making the switching between the first state and the second state of the photovoltaic component easier and smoother.

[0070] In some embodiments, such as Figure 3 , Figure 6 , Figure 9 , Figure 10 and Figure 14As shown, the first strip groove 121 is provided with a first limiting part for restricting the sliding of the first end of the slider 222 relative to the first strip groove 121, and the second strip groove 221 is provided with a second limiting part for restricting the sliding of the second end of the slider 222 relative to the second strip groove 221. In the second state, the first mounting bracket 11 and the second mounting bracket 21 are constrained to continue moving away from each other by the restriction of the first end of the slider 222 by the first limiting part and the restriction of the second end of the slider 222 by the second limiting part. During the process of switching from the first state to the second state, when the first end and the second end of the slider 222 are respectively restricted from further sliding by the first limiting part and the second end of the slider 222 are respectively restricted from further sliding by the second limiting part, the transition to the second state is further achieved by rotating the first end of the slider 222 relative to the first limiting part and rotating the second end of the slider 222 relative to the second limiting part. The first limiting part in this embodiment restricts the sliding limit of the first end of the slider 222 relative to one end of the first strip groove 121. This prevents the first end of the slider 222 from sliding further after reaching the position limited by the first limiting part. At this point, the first end of the slider 222 can rotate relative to the first strip groove 121. In other words, the first limiting part only restricts the sliding position of the first end of the slider 222, but does not restrict its relative rotation. Similarly, the second limiting part restricts the sliding limit of the second end of the slider 222 relative to one end of the second strip groove 221. This prevents the second end of the slider 222 from sliding further after reaching the position limited by the second limiting part. At this point, the second end of the slider 222 can rotate relative to the second strip groove 221. In other words, the second limiting part only restricts the sliding position of the second end of the slider 222, but does not restrict its relative rotation. In this embodiment, by setting the first limiting part and the second limiting part, when the photovoltaic component switches from the first state to the second state, the sliding of the first mounting bracket 11 relative to the second mounting bracket 21 is stable and controllable, ensuring that the first mounting bracket 11 and the second mounting bracket 21 are unfolded to the expected position, thereby ensuring that the relative rotation between the second end and the first end of the sliding member 222 can proceed smoothly, so that the first mounting bracket 11 can move relative to the second mounting bracket 21 in the height direction at the expected position, and realize a reliable switch from the first state to the second state.

[0071] In some embodiments, such as Figure 9 and Figure 10As shown, the first limiting portion includes a first damping member 123 and a second damping member disposed on two opposing groove walls of the first strip groove 121. During the transition from the first state to the second state, when the first end of the slider 222 slides from a position away from the first damping member 123 to a position closer to the first damping member 123 and then simultaneously contacts the first damping member 123 and the second damping member, the first damping member 123 and the second damping member slow down and limit the further sliding of the first end of the slider 222 through friction. Figure 9 and Figure 10 In the illustrated embodiment, the first damping member 123 and the second damping member are located at the ends of the first strip groove 121, and respectively on the upper and lower groove wall surfaces of the first strip groove 121. Specifically, in the embodiment shown in the figure, both ends of the first strip groove 121 are provided with first limiting portions. During the process of switching from the first state to the second state, when the first end of the slider 222 slides from a position not in contact with the first limiting portion to a position in contact with the first limiting portion, the first damping member 123 and the second damping member decelerate the first end of the slider 222 first through friction, and then limit the further movement of the first end of the slider 222 through friction. And / or, the second limiting portion includes a first damping member 123 and a second damping member disposed on the two opposing groove walls of the second strip groove 221. During the transition from the first state to the second state, the second end of the sliding member 222 slides from a position away from the first damping member 123 to a position closer to the first damping member 123, and then, when simultaneously contacting the first damping member 123 and the second damping member, the first damping member 123 and the second damping member slow down and limit the further sliding of the second end of the sliding member 222 through friction. Figure 9 and Figure 10In the illustrated embodiment, the first damping member 123 and the second damping member are located at the ends of the second strip groove 221, respectively on the upper and lower groove walls of the second strip groove 221. Specifically, in the embodiment shown in the figure, both ends of the second strip groove 221 are provided with second limiting portions. During the process of switching from the first state to the second state, when the second end of the sliding member 222 slides from a position not in contact with the second limiting portion to a position in contact with the second limiting portion, after the first damping member 123 and the second damping member contact the second end of the sliding member 222, the second end of the sliding member 222 is located between the first damping member 123 and the second damping member. The second end of the sliding member 222 is decelerated first by friction, and then the further sliding of the second end of the sliding member 222 is restricted by friction. In this embodiment, the first damping element 123 and the second damping element decelerate and limit the end of the sliding element 222 through friction. Compared with directly setting a blocking wall for limiting, the deceleration and limiting process in this embodiment is smooth and gentle, with less impact, which helps to reduce damage to the sliding element 222. In some embodiments, the first damping element 123 and the second damping element are made of resin. Specifically, ABS material (acrylonitrile-butadiene-styrene copolymer) can be selected. While the first damping element 123 and the second damping element can effectively perform the friction deceleration and limiting function, the damage to the sliding element 222 is less, thus enabling the friction deceleration and limiting function to be performed effectively for a long time.

[0072] In some embodiments, such as Figure 14As shown, the first damping member 123 and the second damping member respectively include a first extension member 1231 and a second extension member 1232 connected to each other. The first extension member 1231 and the second extension member 1232 of the first damping member 123 are stepped, and the first extension member 1231 and the second extension member 1232 of the second damping member are stepped. During the process of switching from the first state to the second state, the first end of the slider 222 slides from a position away from the first damping member 123 to a position closer to the first damping member 123. When the first damping member 123 and the second damping member come into contact simultaneously, the first end of the sliding member 222 first comes into contact with the second extension member 1232 of the first damping member 123 and the second damping member and is decelerated by the second extension member 1232 of the first damping member 123 and the second damping member. Then the first end of the sliding member 222 comes into contact with the first extension member 1231 of the first damping member 123 and the second damping member and is restricted from further sliding by the first extension member 1231 of the first damping member 123 and the second damping member. In the embodiment shown in the figure, the first extension member 1231 and the second extension member 1232 are elastic, and the thickness difference between the first extension member 1231 and the second extension member 1232 is small. Due to the small size of the stepped surface formed by the thickness difference, during the process of the end of the slider 222 sliding from not contacting the first limiting part to contacting the first limiting part, it first enters between the second extension member 1232 of the first damping member 123 and the second extension member 1232 of the second damping member 123, and is clamped by the second extension member 1232 of the first damping member 123 and the second extension member 1232 of the second damping member 123 and decelerated by friction. Then, when the end of the slider 222 slides further, the end of the slider 222 crosses the stepped surface between the first extension member 1231 and the second extension member 1232 and enters between the first extension member 1231 of the first damping member 123 and the first extension member 1231 of the second damping member 123, and is further clamped and limited, thus finally achieving effective limiting of the end of the slider 222. In this embodiment, by setting the first delay member 1231 and the second delay member 1232, the sliding process of the end of the slider 222 is divided into two stages: deceleration and limiting. This not only makes the deceleration process smooth and gentle, but also reduces the impact while ensuring reliable limiting, thus achieving a gentler and more stable limiting effect.

[0073] In some embodiments, such as Figures 6-8 , Figure 11 and Figure 12 As shown, the photovoltaic device also includes a flexible first strip curtain 41 and a flexible second strip curtain 42.

[0074] A flexible first strip-shaped baffle 41 is arranged along the first strip-shaped groove 121, and is used to block dust from sliding relative to the first strip-shaped groove 121 and the sliding member 222. A flexible second strip-shaped baffle 42 is arranged along the second strip-shaped groove 221, and is used to block dust from sliding relative to the second strip-shaped groove 221 and the sliding member 222. The first strip-shaped baffle 41 is flexible, and it blocks the first strip-shaped groove 121 to prevent dust from entering the first strip-shaped groove 121. At the same time, because it is flexible, the sliding of the first end of the sliding member 222 on the first strip-shaped groove 121 is not hindered by it. When the first end of the sliding member 222 slides, the first end of the sliding member 222 will gradually lift the first strip-shaped baffle 41. Therefore, the flexible first strip-shaped baffle 41 does not hinder the sliding of the sliding member 222. Similarly, the second strip-shaped baffle 42 does not hinder the sliding of the sliding member 222. In some embodiments, one end of the first strip-shaped baffle 41 in the width direction is connected to one wall of the first strip-shaped groove 121, and the other end is set as a free end. Thus, when the slider 222 slides, a portion of the first strip-shaped baffle 41 along its length direction can be sequentially lifted by the slider 222. After the slider 222 has slid past, the first strip-shaped baffle 41 resumes its blocking function on the first strip-shaped groove 121. This embodiment, by providing a flexible first strip-shaped baffle 41 and a flexible second strip-shaped baffle 42, can prevent dust from obstructing the relative sliding of the first strip-shaped groove 121 and the slider 222, and also prevent dust from obstructing the relative sliding of the second strip-shaped groove 221 and the slider 222, ensuring the reliable and durable operation of the slider 222.

[0075] In some embodiments, such as Figures 6-8 , Figure 11 and Figure 12 As shown, the first strip curtain 41 includes a flexible first blocking portion 411 and a flexible second blocking portion 412 extending along the first strip groove 121, located on opposite walls of the first strip groove 121. The first blocking portion 411 includes a first serrated structure protruding toward the second blocking portion 412. The first serrated structure includes a plurality of protrusions 43 spaced apart along the first strip groove 121 and protruding toward the second blocking portion 412. The second blocking portion 412 includes a second serrated structure protruding toward the first blocking portion 411. The second serrated structure includes a plurality of protrusions 43 spaced apart along the second strip groove 221 and protruding toward the first blocking portion 411. The protrusions 43 of the second serrated structure and the protrusions 43 of the first serrated structure are arranged alternately.

[0076] The second strip curtain 42 includes a flexible third shielding portion 421 and a flexible fourth shielding portion 422 extending along the second strip groove 221, located on opposite two groove walls of the second strip groove 221. The third shielding portion 421 includes a third serrated structure protruding toward the fourth shielding portion 422. The third serrated structure includes a plurality of protrusions 43 that are spaced apart along the second strip groove 221 and protruding toward the fourth shielding portion 422. The fourth shielding portion 422 includes a fourth serrated structure that protrudes toward the third shielding portion 421. The fourth serrated structure includes a plurality of protrusions 43 that are spaced apart along the second strip groove 221 and protruding toward the third shielding portion 421. The protrusions 43 of the fourth serrated structure and the protrusions 43 of the third serrated structure are arranged alternately. In this embodiment, the first strip curtain 41 and the second strip curtain 42 are configured as a double sawtooth structure with multiple protrusions 43, and the upper and lower sawtooth structures are arranged alternately. This can reliably and effectively block the sliding of the sliding member 222 and the strip groove. The position where the upper and lower sawtooth structures cooperate is located in the middle of the strip groove, which is easy to be lifted by the sliding member 222 when sliding, thus reducing the resistance to the sliding of the sliding member 222 and ensuring the reliable movement of the sliding member 222.

[0077] In some embodiments, such as Figures 6-10 As shown, the photovoltaic device also includes one or more first pads 5 fixedly mounted on the first mounting frame 11 or the second mounting frame 21. In the first state, the first pads 5 support the first mounting frame 11 on the second mounting frame 21 and keep the first mounting frame 11 and the second mounting frame 21 spaced apart along the height direction of the second mounting frame 21. In the embodiment shown, the first pads 5 are fixedly connected to the first mounting frame 11. In this embodiment, in the first state of the photovoltaic components, i.e., when the first photovoltaic module 1 and the second photovoltaic module 2 are folded, the first pads 5 are located between the first photovoltaic module 1 and the second photovoltaic module 2. The first pads 5 can separate the first photovoltaic module 1 and the second photovoltaic module 2, reduce wear between the first photovoltaic module 1 and the second photovoltaic module 2, and also facilitate the sliding between the first photovoltaic module 1 and the second photovoltaic module 2 when the photovoltaic components change states.

[0078] In some embodiments, such as Figures 6-10As shown, the photovoltaic device includes a plurality of first pads 5 fixedly mounted on a first mounting frame 11 and spaced apart. The plurality of first pads 5 are located on the same plane facing the top of the second mounting frame 21. When switching from a first state to a second state, the plurality of first pads 5 slide on the surface of the second photovoltaic module 2. In the embodiment shown, the end face of the first pad 5 is an arc-shaped end face. In this embodiment, by setting a plurality of first pads 5 and positioning the tops of the plurality of first pads 5 on the same plane, the plurality of first pads 5 can better separate the first photovoltaic module 1 and the second photovoltaic module 2. Furthermore, when the state of the photovoltaic components changes, the sliding of the plurality of first pads 5 on the surface of the second photovoltaic module 2 makes the sliding of the first photovoltaic module 1 and the second photovoltaic module 2 more stable and smooth.

[0079] In some embodiments, such as Figure 1 , Figures 4 to 10 As shown, the photovoltaic component also includes a third photovoltaic module 3. The third photovoltaic module 3 includes a third mounting frame 31, a solar photovoltaic panel 100 located on the third mounting frame 31, and a third connecting structure slidably engaged with the second connecting structure 22 on the third mounting frame 31. In the embodiment shown, the third connecting structure includes a third strip groove 321. In the first state, the third mounting frame 31 is located below the second mounting frame 21 and is folded relative to the second mounting frame 21. In the second state, the third mounting frame 31 is located to the side of the second mounting frame 21 and is unfolded relative to the second mounting frame 21. Along the height direction of the second mounting frame 21, the height of the third mounting frame 31 relative to the second mounting frame 21 in the second state is greater than its height relative to the second mounting frame 21 in the first state. In this embodiment, by setting the third photovoltaic module 3, the photovoltaic component has a larger unfolded area when unfolded in the second state, and can generate more electricity through solar radiation.

[0080] In some embodiments, such as Figure 1 , Figure 2 , Figure 15 and Figure 16As shown, the photovoltaic device also includes two support members 6. The support members 6 are connected to both sides of the photovoltaic component and are used to support the photovoltaic component. The connection position between the support members 6 and the photovoltaic component can be adjusted to regulate the angle between the photovoltaic component and the horizontal plane. In some embodiments, the photovoltaic component has multiple connection positions for connecting with the support members 6. The connection positions on the support members 6 and the photovoltaic component remain unchanged, while the connection positions on the photovoltaic component and the support members 6 are changed, thereby adjusting the connection position between the support members 6 and the photovoltaic component. In some embodiments, the support members 6 have multiple connection positions for connecting with the photovoltaic component. The connection positions on the photovoltaic component and the support members 6 remain unchanged, while the connection positions on the support members 6 and the photovoltaic component are changed, thereby adjusting the connection position between the support members 6 and the photovoltaic component. In this embodiment, the two support members 6 can provide reliable support for the photovoltaic component, and the angle between the photovoltaic component and the horizontal plane can be adjusted by regulating the connection position between the support members 6 and the photovoltaic component.

[0081] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 , Figure 15 and Figure 16 As shown, the support member 6 includes a main rod 61, a ground support rod 62, a friction plate 65, a connecting rod 63, and an adjusting rod 64 hinged to the main rod 61. The adjusting rod 64 is also connected to the photovoltaic module, and its connection position is adjustable. In the embodiment shown, the photovoltaic module has multiple connecting parts along its length for connecting to the adjusting rod 64. The adjusting rod 64 adjusts its connection position with the photovoltaic module by connecting to different connecting parts. The connecting rod 63 is connected to the main rod 61, and the ground support rod 62 is hinged to the main rod 61. The connecting rod 63 and the ground support rod 62 support the main rod 61 on the ground. The ground support rod 62 is fixed to the ground by means of threaded connections, which makes the support of the ground support rod 62 for the photovoltaic module more reliable. The friction plate 65 is connected to both the main rod 61 and the ground support rod 62 to generate frictional resistance to the rotation of the ground support rod 62 relative to the main rod 61. In the embodiment shown in the figure, the ground support rod 62 and the main rod 61 are hinged by the same bolt passing through them, and then clamped by the first clamping plate 621 and the second clamping plate 622 on the outside of the bolt. A friction plate 65 is disposed between the first clamping plate 621 and the second clamping plate 622, and the friction plate 65 contacts both the main rod 61 and the ground support rod 62. When unfolded, the support member 6 of this embodiment can... Figure 1 As shown, it provides reliable support for the photovoltaic components, and when folded, as... Figure 5As shown, the volume is reduced, making transportation easier. Simultaneously, the friction pads 65, when the support member 6 supports the photovoltaic module, can absorb some vibrations between the connecting rod 63 and the ground support rod 62 through friction, reducing the transmission of vibrations to the photovoltaic module and improving its operational stability.

[0082] In some embodiments, such as Figures 17 to 24 As shown, to further reduce the vibration of the solar photovoltaic panel 100, the first photovoltaic module 1 further includes a buffer 13 disposed between the first mounting frame 11 and the solar photovoltaic panel 100, and / or, the second photovoltaic module 2 further includes a buffer 13 disposed between the second mounting frame 21 and the solar photovoltaic panel 100; the buffer 13 includes rubber 131 and a metal part 132 disposed inside the rubber 131. In this embodiment, the structure of the rubber 131 in the buffer 13 can effectively buffer and reduce vibration of the solar photovoltaic panel 100. The metal part 132 disposed inside the rubber 131 can maintain the shape of the rubber 131, improving the rubber 131's resistance to damage under shear force and also improving the rubber 131's impact resistance.

[0083] In some embodiments, such as Figure 22 As shown, the metal part 132 is a plate-shaped part, and the outer contour of the plate-shaped part is wavy. In this embodiment, the outer contour of the metal part 132 is a wave-like shape with high and low undulations. When the buffer 13 is subjected to small vibration impact, the rubber 131 can buffer and absorb the small vibration. When the buffer 13 encounters a large vibration impact, the metal part 132 located in the rubber 131 can withstand a large vibration impact through metal deformation. The buffer 13 in this embodiment can buffer a large range of vibrations.

[0084] In some embodiments, such as Figures 22 to 24 As shown, the plate-shaped component is an annular plate-shaped component. After unfolding the annular plate-shaped component circumferentially, the outer contour line of the annular plate-shaped component is a sine curve. That is, for... Figure 23 The annular plate shown is cut open radially, and then unfolded. The shape of part of the outer contour of the annular plate is as follows: Figure 24 As shown, it includes a first line 1321 located above and a second line 1322 located below. In this embodiment, the first line 1321 and the second line 1322 have the same shape and are equidistant from each other. Both the first line 1321 and the second line 1322 are part of a sine curve. This embodiment improves the damping effect by setting the outer contour of the annular plate-shaped member to be part of a sine curve, and the annular plate-shaped member is easy to manufacture.
