[0049] Because the noise generated by cars traveling at high speeds seriously affects people's lives, sound barriers are installed on both sides of the road near residential areas in related technologies. However, the function of sound barriers is relatively simple.

[0050] In order to enhance the functionality of sound barriers, this application proposes a photovoltaic sound barrier.

[0051] Please refer to the reference. Figures 1 to 5 In one embodiment of this application, the photovoltaic sound barrier 1 includes a fixed frame 100, a photovoltaic panel 200, a sound insulation board 300, a first limiting component 400, and a second limiting component 500. The fixed frame 100 is provided with a first frame 110 and a second frame 120, and a limiting frame is provided on the fixed frame 100. The limiting frame, together with the first frame 110 and the second frame 120, defines an installation frame position. The photovoltaic panel 200 is installed in the installation frame position. The sound insulation board 300 is installed in the installation frame position and is stacked with the photovoltaic panel 200. The first limiting component 400 is connected to the fixed frame 100 and limits the side of the photovoltaic panel 200 away from the sound insulation board 300. The second limiting component 500 is connected to the fixed frame 100 and limits the side of the sound insulation board 300 away from the photovoltaic panel 200.

[0052] The fixed frame 100 in the photovoltaic sound barrier 1 has mounting positions for fixing the photovoltaic panel 200 and the sound insulation board 300, thereby achieving good support for the photovoltaic panel 200 and the sound insulation board 300. The mounting positions can be rectangular, circular, or other shapes. Specifically, when the mounting frame is rectangular, the first frame 110 and the second frame 120 are both straight lines, and the limiting frame, which is the frame connecting the first frame 110 and the second frame 120, is also straight. When the mounting frame is circular, the first frame 110 and the second frame 120 are both curved, and the limiting frame, which is the frame connecting the first frame 110 and the second frame 120, is also curved. To achieve better sound insulation and installation stability, the shape of the mounting positions is adapted to the shape of the photovoltaic panel 200 and the sound insulation board 300. The fixed frame 100 can have one, two, or more mounting positions. When there are multiple mounting frames, the multiple mounting frames can be arranged along the length direction of the fixed frame 100 or along the width direction of the fixed frame 100.

[0053] like Figure 7As shown, the photovoltaic noise barrier 1 can be applied to both sides of municipal roads 2 near residential areas, or it can also be applied to both sides of highways 2. When photovoltaic panels 200 and sound insulation panels 300 are stacked in the mounting frame of the fixed frame 100, the sound insulation panels 300 can be located on the side of the fixed frame 100 closer to the road 2, and the photovoltaic panels 200 can be located on the side of the fixed frame 100 away from the road 2; or the sound insulation panels 300 can be located on the side of the fixed frame 100 away from the road 2, and the photovoltaic panels 200 can be located on the side of the fixed frame 100 closer to the road 2.

[0054] The first limiting component 400 is connected to the fixed frame 100 and can limit the side of the photovoltaic panel 200 away from the sound insulation board 300, thereby reducing the likelihood of the photovoltaic panel 200 and the sound insulation board 300 detaching from the opening on the side of the mounting frame closest to the photovoltaic panel 200. The first limiting component 400 may include at least a first limiting member, which may be a plate-like body, a block-like body, or a column-like body, etc. The first limiting member may be fixedly connected to the fixed frame 100. For example, the first limiting component 400 may also include fasteners to fix the first limiting member to the fixed frame 100; or the first limiting member may also be fixedly connected to the fixed frame 100 by welding to limit the surface of the photovoltaic panel 200 away from the sound insulation board 300. The first limiting component can also be movably installed on the fixed frame 100. For example, the first limiting component can be rotatably installed on the fixed frame 100 or slidably installed on the fixed frame 100. This allows the opening on the side of the mounting frame closest to the photovoltaic panel 200 to be avoided by changing the state of the first limiting component, so that the photovoltaic panel 200 and the sound insulation board 300 can be installed in the mounting frame through the opening on the side of the mounting frame closest to the photovoltaic panel 200. After the photovoltaic panel 200 and the sound insulation board 300 are installed in the mounting frame, the state of the first limiting component can be changed again so that the first limiting component can limit the side of the photovoltaic panel 200 away from the sound insulation board 300.

[0055] The second limiting component 500 is connected to the fixed frame 100 and can limit the side of the sound insulation panel 300 away from the photovoltaic panel 200, thereby reducing the likelihood of the photovoltaic panel 200 and the sound insulation panel 300 detaching from the opening on the side of the mounting frame closest to the sound insulation panel 300. The second limiting component 500 may include at least a second limiting member, which may be a plate-like body, a block-like body, or a column-like body, etc. The second limiting member can be fixedly connected to the fixed frame 100. For example, the second limiting component 500 may also include fasteners to fix the second limiting member to the fixed frame 100; or the second limiting member may also be fixedly connected to the fixed frame 100 by welding to limit the surface of the sound insulation panel 300 away from the photovoltaic panel 200. The second limiting component can also be movably installed on the fixed frame 100. For example, the second limiting component can be rotatably disposed on the fixed frame 100 or slidably disposed on the fixed frame 100. This allows the opening on the side of the mounting frame closest to the sound insulation panel 300 to be avoided, facilitating the installation of the photovoltaic panel 200 and the sound insulation panel 300 through the opening on the side of the mounting frame closest to the sound insulation panel 300. After the photovoltaic panel 200 and the sound insulation panel 300 are installed in the mounting frame, the state of the second limiting component can be changed again to limit the side of the sound insulation panel 300 away from the photovoltaic panel 200. The first limiting component 400 in this application can use the same component as the second limiting component 500, or it can use a different component.

[0056] It should be noted that, in order to facilitate the installation of the photovoltaic panel 200 and the sound insulation panel 300, at least one of the first limiting component 400 and the second limiting component 500 in the technical solution of this application can be detachably connected to the fixed frame 100; or, at least one of the first limiting component 400 and the second limiting component 500 can be movably disposed on the fixed frame 100, so that the one of the first limiting component 400 and the second limiting component 500 that is relatively movable to the fixed frame 100 can have an avoidance state and a limiting state. In the avoidance state, it can avoid the photovoltaic panel 200 and the sound insulation panel 300 from being installed in the installation frame position in at least one direction of the installation frame; in the limiting state, it can limit the photovoltaic panel 200 and the sound insulation panel 300, reducing the photovoltaic panel 200 and the sound insulation panel 300 from leaving the installation frame position.

[0057] The technical solution of this application, by installing both the photovoltaic panel 200 and the sound insulation panel 300 within the installation frame, and stacking the sound insulation panel 300 with the photovoltaic panel 200, enables the photovoltaic sound barrier 1 of this application to have both sound insulation and photovoltaic power generation functions. By connecting the first limiting component 400 to the fixed frame 100 and limiting the side of the photovoltaic panel 200 away from the sound insulation panel 300; and connecting the second limiting component 500 to the fixed frame 100 and limiting the side of the sound insulation panel 300 away from the photovoltaic panel 200, the first limiting component 400 and the second limiting component 500 can jointly and stably confine the photovoltaic panel 200 and the sound insulation panel 300 within the installation frame, thereby improving the installation stability of the photovoltaic panel 200 and the sound insulation panel 300 and reducing the risk of the photovoltaic panel 200 and the sound insulation panel 300 falling off.

[0058] Please refer to the reference. Figure 1 , Figure 3 , Figure 4 as well as Figure 5 In some embodiments of this application, the first limiting component 400 includes a first limiting plate 410, a first bolt 420, and a first nut 430. The first limiting plate 410 is fixedly disposed on the fixed frame 100 and located on the side of the photovoltaic panel 200 away from the sound insulation board 300. The first bolt 420 passes through the first limiting plate 410 and the fixed frame 100. The first nut 430 is disposed on the side of the fixed frame 100 away from the first limiting plate 410 and is threadedly connected to the first bolt 420.

[0059] This configuration allows the first limiting plate 410 to be stably mounted on the fixed frame 100 and located on the side of the photovoltaic panel 200 away from the sound insulation board 300, thus achieving the effect of limiting the photovoltaic panel 200 on the side away from the sound insulation board 300. Furthermore, by passing the first bolt 420 through the first limiting plate 410 and the fixed frame 100, and threading the first nut 430 to the first bolt 420 on the side of the fixed frame 100 away from the first limiting plate 410, the structure of the first limiting component 400 is relatively simple, and it facilitates the assembly and disassembly of the first limiting component 400 from the fixed frame 100, reducing the replacement cost of the first limiting component 400.

[0060] Specifically, during the installation process, the first limiting plate 410 of the first limiting component 400 can be pre-installed on the fixed frame 100 before the fixed frame 100 leaves the factory. Then, at the construction site, it is only necessary to install the photovoltaic panel 200 and the sound insulation board 300 in the installation frame position through the side of the fixed frame 100 away from the first limiting plate 410. At this time, the first limiting plate 410 of the first limiting component 400 has a good limiting effect on the photovoltaic panel 200 and the sound insulation board 300, reducing the risk of the photovoltaic panel 200 and the sound insulation board 300 coming off the side of the fixed frame 100 close to the first limiting plate 410. Of course, the first limiting component 400 can also be installed on the construction site. That is, the operator can first set the first limiting plate 410 on one side of the fixed frame 100 on the construction site. After the first bolt 420 passes through the first limiting plate 410 and the fixed frame 100 from one side of the fixed frame 100, the nut is locked on the first bolt 420 on the side of the fixed frame 100 away from the first limiting plate 410, thereby achieving the effect of installing the first limiting component 400 on the fixed frame 100. Then, the photovoltaic panel 200 and the sound insulation board 300 are installed in the installation frame through the opening on the side of the fixed frame 100 away from the first limiting plate 410. Finally, the second limiting component 500 is installed on the fixed frame 100, and the sound insulation board 300 is limited on the side away from the photovoltaic panel 200.

[0061] Please refer to the reference. Figure 1 , Figure 3 , Figure 4 as well as Figure 5 Furthermore, the first limiting component 400 also includes two limiting blocks 440 fixed on the fixed frame 100, and the first limiting plate 410 is engaged between the two opposing limiting blocks 440.

[0062] By setting two opposing limiting blocks 440 in the direction perpendicular to the axis of the first bolt 420, and having the first limiting plate 410 inserted between the two limiting blocks 440, the two limiting blocks 440 can reduce the risk that the first limiting plate 410 will be unable to limit the photovoltaic panel 200 and the sound insulation board 300 due to rotation relative to the first bolt 420, thereby improving the limiting stability of the first limiting plate 410 on the photovoltaic panel 200 and the sound insulation board 300.

[0063] Specifically, when the photovoltaic noise barrier 1 is applied to an elevated bridge, the side of the fixed frame 100 closest to the photovoltaic panel 200 can be the side facing away from the road 2 of the elevated bridge, i.e., the outer side of the elevated bridge. In this case, the first limiting component 400 can be pre-installed on the fixed frame 100 before it leaves the factory to reduce the risk that operators will have difficulty assembling the first limiting component 400 on the side facing away from the elevated bridge on the construction site. In addition, based on the installation state of the fixed frame 100 installed on both sides of the road 2, in order to facilitate the connection between the limiting block 440 and the fixed frame 100, the limiting block 440 can be arranged in the vertical direction of the fixed frame 100. The limiting block 440 can be welded to the fixed frame 100, or the limiting block 440 can be fixedly connected to the fixed frame 100 by screw fastening, or the limiting block 440 can be fixedly connected to the fixed frame 100 by snap-fit, etc.

[0064] Please refer to the reference. Figure 2 , Figure 3 , Figure 4 as well as Figure 5 In some embodiments of this application, the second limiting component 500 includes a second limiting plate 510, a second bolt 520, and a second nut 530. The second limiting plate 510 is disposed on the fixed frame 100 and located on the side of the sound insulation plate 300 away from the photovoltaic panel 200. The second bolt 520 passes through the second limiting plate 510 and the fixed frame 100. The second nut 530 is disposed on the side of the fixed frame 100 away from the second limiting plate 510 and is threadedly connected to the second bolt 520.

[0065] This configuration allows the second limiting plate 510 to be stably positioned on the fixed frame 100, thereby limiting the sound insulation plate 300 on the side away from the photovoltaic panel 200. Furthermore, by passing the second bolt 520 through the second limiting plate 510 and the fixed frame 100, and by threading the second nut 530 to the second bolt 520 on the side of the fixed frame 100 away from the second limiting plate 510, the second limiting assembly 500 provides a stable limiting effect on both the photovoltaic panel 200 and the sound insulation plate 300.

[0066] Please refer to the reference. Figure 2 , Figure 3 , Figure 4 as well as Figure 5 In some embodiments of this application, the second nut 530 is rotatably disposed on the side of the fixed frame 100 away from the second limiting plate 510, and can rotate about the axis of the second bolt 520.

[0067] By rotating the second nut 530 to the side of the fixed frame 100 away from the second limiting plate 510, the second bolt 520, threadedly connected to the second nut 530, can move along its own axis when the second nut 530 rotates relative to the fixed frame 100. When the second nut 530 rotates so that the second bolt 520 moves from the side of the fixed frame 100 near the second limiting plate 510 to the side away from the second limiting plate 510, the second bolt 520 releases its clamping effect on the second limiting plate 510. This allows the second limiting plate 510 to rotate around the axis of the second bolt 520 and also move along the axis of the second bolt 520. This facilitates the movement of the second limiting plate 510 to a clearance position, allowing it to avoid obstructing the installation of the photovoltaic panel 200 and the partition from the side of the fixed frame 100 near the second limiting plate 510 into the installation frame, thereby reducing the risk of the second limiting component 500 blocking the installation of the photovoltaic panel 200 and the partition.

[0068] Please refer to the reference. Figures 2 to 6 In some embodiments of this application, the second nut 530 is snapped into the fixing frame 100.

[0069] Specifically, when the second nut 530 is engaged with the fixed frame 100, it can be engaged by a snap-fit ​​connection or by the cooperation of both, as long as the second nut 530 is not easily dislodged from the fixed frame 100 and the rotation of the second nut 530 relative to the fixed frame 100 is not affected.

[0070] By engaging the second nut 530 with the fixed frame 100, the connection between the second nut 530 and the fixed frame 100 is made more stable, reducing the risk of the second nut 530 detaching from the fixed frame 100. In addition, this design also allows the second nut 530 to be removed from the fixed frame 100, thereby facilitating the assembly and disassembly of the second nut 530.

[0071] Please refer to the reference. Figures 2 to 6 In some embodiments of this application, the fixed frame 100 is provided with a first snap-fit ​​portion 102, and the second nut 530 is provided with a second snap-fit ​​portion 531; and the first snap-fit ​​portion 102 and the second snap-fit ​​portion 531 are snapped together.

[0072] This configuration makes the engagement between the second nut 530 and the fixed frame 100 more secure, further reducing the risk that the second nut 530 will detach from the fixed frame 100 along the direction away from the second limiting plate 510.

[0073] Specifically, in one example, the first snap-fit ​​portion 102 can be a buckle protruding from the fixed frame 100, and the end face of the second nut 530 is provided with an annular snap hole spaced apart from its own threaded hole. The center of the annular snap hole coincides with the center of the threaded hole, and the buckle snaps into the snap hole. This allows the second nut 530 to rotate relative to the fixed frame 100 while reducing the risk of it disengaging from the fixed frame 100 in the direction away from the second limiting plate 510. Alternatively, in another example, the first snap-fit ​​portion 102 can be an annular snap hole, and the second snap-fit ​​portion 531 on the second nut 530 can be a buckle.

[0074] Please refer to the reference. Figures 2 to 6 In some embodiments of this application, the fixed frame 100 is provided with an insertion hole 101, and the first snap-fit ​​part 102 is provided on the inner wall of the insertion hole 101; the second nut 530 is inserted into the insertion hole 101, and the second snap-fit ​​part 531 is provided on the outer peripheral wall of the second nut 530.

[0075] By inserting the second nut 530 into the socket 101, the second nut 530 can be at least partially hidden within the socket 101, thereby reducing the space occupied by the second nut 530 protruding from the fixing frame 100 and improving space utilization. Furthermore, by providing the first snap-fit ​​portion 102 on the inner wall of the socket 101 and the second snap-fit ​​portion 531 on the outer peripheral wall of the second nut 530, the second nut 530 simultaneously engages with the fixing frame 100 after being inserted into the socket 101, thus improving the efficiency of assembling the second nut 530 with the fixing frame 100.

[0076] Please refer to Figure 5 As shown, in some embodiments of this application, the fixed frame 100 is provided with an installation cavity, and the photovoltaic sound barrier 1 also includes an elastic element 540 and a limiting element 550. The elastic element 540 is located in the installation cavity; the limiting element 550 is located in the installation cavity and is fixedly disposed on the second bolt 520, and one end of the elastic element 540 abuts against the limiting element 550; when the second bolt 520 moves axially, it can compress or stretch the elastic element 540 through the limiting element 550.

[0077] The elastic element 540 can be a spring or a spring sheet, etc. When the elastic element 540 is a spring, the spring can be sleeved outside the second bolt 520, that is, the spring also passes through the second bolt 520 as it passes from one side of the fixing frame 100 to the other. This arrangement can ensure that the spring can expand and contract well along the axial direction of the second bolt 520 when it expands and contracts. Of course, if the guiding function of the expansion and contraction of the elastic element 540 is not considered, the second bolt 520 can also be without the elastic element 540 passing through it.

[0078] The limiting component 550 can be a limiting plate, limiting post, limiting piece, or limiting block 440, etc., as long as it can limit one end of the elastic member 540, so that the elastic member 540 can be compressed or stretched when the limiting component 550 moves with the second bolt 520. The limiting component 550 can be a limiting piece or a limiting plate, with a threaded hole, and the first bolt 420 can be threadedly fastened to the threaded hole of the limiting piece or the limiting plate; the limiting piece or the limiting plate can also have a through hole, through which the first bolt 420 passes, and adhesive is applied between the first bolt 420 and the inner wall of the through hole. The limiting component 550 can also be a limiting post, which can protrude from the side wall of the first bolt 420, or can be connected to the side wall of the first bolt 420 by snap-fit ​​or threaded connection.

[0079] By installing an elastic element 540 in the mounting cavity of the fixed frame 100, and having one end of the elastic element 540 abut against the limiting element 550 fixedly connected to the second bolt 520, the second bolt 520 can compress or stretch the elastic element 540 through the limiting element 550 when it moves axially. This allows the second bolt 520 to exert reverse pressure on the second nut 530 through the elastic force of the elastic element 540 when it loosens the second limiting plate 510. This avoids the risk that the second bolt 520 will move too far along the direction from the second nut 530 to the second limiting plate 510 and disengage from the second nut 530, which would prevent the second nut 530 from rotating and thus being unable to drive the second bolt 520 to lock the second limiting plate 510 in the opposite direction along the direction from the second limiting plate 510 to the second nut 530.

[0080] Please refer to Figure 5 As shown, the photovoltaic sound barrier 1 further includes a gasket 560, which is disposed in the mounting cavity and on the side of the elastic member 540 away from the limiting member 550.

[0081] By providing a shim 560 on the side of the elastic member 540 away from the limiting member 550, the elastic member 540 can be effectively compressed or stretched under the driving action of the limiting member 550.

[0082] Specifically, the second bolt 520 may or may not have a washer 560 inserted through it. Understandably, when the second bolt 520 has a washer 560 inserted through it, the risk of the washer 560 moving in the direction perpendicular to the second bolt 520 can be reduced, thereby ensuring that the washer 560 can maintain a good limiting effect on the side of the elastic member 540 away from the limiting member 550.

[0083] Please refer to Figure 5As shown, in some embodiments of this application, the second limiting plate 510 includes a plate body 511 and a limiting pin 512. The plate body 511 has a through hole for the second bolt 520 to pass through. The fixed frame 100 has an insertion hole 101, and the limiting pin 512 is fixedly disposed on the plate body 511 and inserted into the insertion hole 101.

[0084] The plate 511 can be rectangular, circular, or other shapes. To facilitate manufacturing and to allow the photovoltaic panel 200 and sound insulation panel 300 to be installed in the mounting frame position from the side of the fixed frame 100 near the second limiting plate 510 when the plate 511 rotates, and to limit the photovoltaic panel 200 and sound insulation panel 300 from the side of the fixed frame 100 near the second limiting plate 510, the plate 511 can be rectangular or other irregularly shaped. The plate 511 is provided with through holes, which can be circular, rectangular, or other shapes.

[0085] When the limiting pin 512 is fixedly installed on the plate 511, it can be integral with the plate 511, or it can be fixed to the plate 511 by means of plugging or snapping.

[0086] By setting a limiting pin 512 on the plate body 511 of the second limiting plate 510, and providing an insertion hole 101 in the fixed frame 100, and inserting the limiting pin 512 into the insertion hole 101, the second bolt 520 can be locked by the second nut 530. When the second bolt 520 can press the second limiting plate 510 against the fixed frame 100, the risk of rotation of the second limiting plate 510 can be reduced, thereby improving its good limiting effect on the photovoltaic panel 200 and the sound insulation board 300.

[0087] like Figure 1 or Figure 2 As shown, in some embodiments of this application, the first limiting component 400 and the second limiting component 500 are spaced apart in the direction perpendicular to the first border 110 to the second border 120.

[0088] This configuration improves the stability of the photovoltaic panel 200 and the sound insulation panel 300 after installation.

[0089] Specifically, when the photovoltaic noise barrier 1 of this application is applied to both sides of the road 2, the first frame 110 and the second frame 120 of the fixed frame 100 are respectively the top and bottom ends of the fixed frame 100, and the first limiting component 400 and the second limiting component 500 can be spaced apart in the direction from the top to the bottom of the fixed frame 100. Alternatively, the first frame 110 and the second frame 120 of the fixed frame 100 are two frames that are respectively arranged opposite each other along the length direction of the road 2, in which case the first limiting component 400 and the second limiting component 500 can also be spaced apart along the length direction of the road 2.

[0090] This application also proposes a photovoltaic system, such as Figure 7 As shown, the photovoltaic system includes a photovoltaic sound barrier 1. The specific structure of the photovoltaic sound barrier 1 is as described in the above embodiments. Since this photovoltaic system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0091] Specifically, the photovoltaic noise barrier 1 can be installed on both sides of the road 2, and support bases 3 are provided on both sides of the road 2. The photovoltaic noise barrier 1 can be installed on the support bases 3.

[0092] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
