[0002] Railway roadbed sound barrier is an acoustic facility that stands between the train and the sound receiving point (such as surrounding residential areas, schools, etc.). It effectively attenuates sound energy through acoustic effects such as reflection, absorption and transmission, thereby reducing the propagation distance and intensity of noise and protecting the sound environment quality in a specific area.

[0003] For linear railway projects, the railway embankment slope covers a large area and has a certain slope, which is the best place to apply photovoltaics along the railway.

[0004] At present, roadbed sound barriers and photovoltaics are generally independently set up with foundations and supports on the roadbed slopes. This method is easy to change the original structure of the slope and increase the difficulty of slope support. If the design or construction is improper, it may cause soil sliding and roadbed collapse. Photovoltaics also affect the vegetation under or around the support, reducing the overall stability of the slope. Summary of the invention

[0005] The main purpose of the present invention is to propose an integrated photovoltaic sound barrier system and a railway roadbed structure, aiming to solve the problem of high difficulty and poor stability of roadbed slope support of existing railways.

[0006] To achieve the above-mentioned purpose, the present invention proposes an integrated photovoltaic sound barrier system, including a sound barrier assembly and a photovoltaic assembly, wherein the sound barrier assembly includes a sound barrier unit panel and at least two sound barrier columns arranged on the roadbed slope, and the sound barrier unit panel is installed between two of the sound barrier columns, and the photovoltaic assembly includes a photovoltaic unit panel and a photovoltaic column arranged on the roadbed slope, one end of the photovoltaic unit panel is mounted on the sound barrier assembly, and the other end is supported by the photovoltaic column.

[0007] According to some embodiments of the present invention, the present invention further includes two rows of foundations buried in the roadbed slope at intervals along the inclination direction of the roadbed slope, wherein one row of the foundations is provided with the sound barrier columns, and the other row of the foundations is provided with the photovoltaic columns.

[0008] According to some embodiments of the present invention, there are multiple sound barrier columns and multiple photovoltaic columns, and the multiple foundations are distributed in an array, and each of the foundations is correspondingly provided with the sound barrier column or the photovoltaic column.

[0009] According to some embodiments of the present invention, the sound barrier column is arranged on the foundation close to the side of the rail.

[0010] According to some embodiments of the present invention, the photovoltaic column is provided with a mounting bracket for installing communication cables and power cables.

[0011] According to some embodiments of the present invention, the photovoltaic assembly further includes a photovoltaic bracket, the top of each sound barrier column is connected to the top of an adjacent photovoltaic column through the photovoltaic bracket, and the photovoltaic unit panel is disposed in the photovoltaic bracket.

[0012] In addition, the present invention also provides a railway roadbed structure, including a rail, two roadbed slopes, at least one contact network and two photovoltaic sound barrier integrated systems as described in any one of the above items, the two roadbed slopes are respectively located on both sides of the rail, the two photovoltaic sound barrier integrated systems are respectively arranged on the two roadbed slopes, and the contact network is arranged between the photovoltaic sound barrier integrated system and the rail.

[0013] According to some embodiments of the present invention, a maintenance walkway is further included, and the maintenance walkway is laid on the roadbed slope along the inclination direction of the roadbed slope.

Since the sound barrier unit panel is only connected to the side of the sound barrier column, and the photovoltaic unit panel is installed on the top of each column, the sound barrier unit panel and the photovoltaic unit panel do not interfere with each other, so through the sharing of the sound barrier assembly, one end of the photovoltaic unit panel can be mounted on the sound barrier column or the sound barrier unit panel, and the photovoltaic column is used to support the other end of the photovoltaic unit panel to achieve the installation of the photovoltaic unit panel.

[0026] The present invention provides a photovoltaic sound barrier integrated system and a railway roadbed structure. Figure 1 to Figure 2 A specific embodiment of a photovoltaic sound barrier integrated system and a railway roadbed structure provided by the present invention.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an integrated photovoltaic sound barrier system 100, including a sound barrier component 1 and a photovoltaic component 2, wherein the sound barrier component 1 includes a sound barrier unit panel 11 and at least two sound barrier columns 12 arranged on the roadbed slope 300, the sound barrier unit panel 11 is installed between the two sound barrier columns 12, the photovoltaic component 2 includes a photovoltaic unit panel 21 and a photovoltaic column 22 arranged on the roadbed slope 300, one end of the photovoltaic unit panel 21 is mounted on the sound barrier component 1, and the other end is supported by the photovoltaic column 22.

[0028] In the present invention, the sound barrier assembly 1 includes a sound barrier unit panel 11 and at least two sound barrier columns 12 arranged on the roadbed slope 300, the sound barrier unit panel 11 is installed between the two sound barrier columns 12, and the photovoltaic assembly 2 includes a photovoltaic unit panel 21 and a photovoltaic column 22 arranged on the roadbed slope 300, one end of the photovoltaic unit panel 21 is mounted on the sound barrier assembly 1, and the other end is supported by the photovoltaic column 22. Since the sound barrier unit panel 11 is only connected to the side of the sound barrier column 12, and the photovoltaic unit panel 21 is installed on the top of each column, the sound barrier unit panel 11 and the photovoltaic unit panel 21 do not interfere with each other, so through the sharing of the sound barrier assembly 1, one end of the photovoltaic unit panel 21 can be mounted on the sound barrier column 12 or the sound barrier unit panel 11, and the photovoltaic column 22 is used to support the other end of the photovoltaic unit panel 21, so as to realize the installation of the photovoltaic unit panel 21. In this way, by sharing the sound barrier assembly 1, the number of photovoltaic columns 22 can be reduced, and the floor space of the photovoltaic sound barrier integrated system 100 can be reduced, so as to reduce the difficulty of supporting the slope and improve the overall stability of the slope. The photovoltaic sound barrier integrated system 100 and the railway roadbed structure 1000 provided by the present invention solve the problem of high difficulty in supporting the roadbed slope 300 of the existing railway and poor stability.

[0029] The sound barrier column 12 and the photovoltaic column 22 are both installed on the roadbed slope 300, and the sound barrier column 12 is installed with a sound barrier unit panel 11, and the sound barrier column 12 and the photovoltaic column 22 are mounted with the photovoltaic unit panel 21. In order to make the sound barrier column 12 and the photovoltaic column 22 more firmly fixed and avoid the collapse of the two columns due to bad weather, which affects the normal use of the sound barrier unit panel 11 and the photovoltaic unit panel 21, in some embodiments, as Figure 1 As shown, the photovoltaic sound barrier integrated system 100 also includes two rows of foundations 3 buried in the roadbed slope 300 at intervals along the inclination direction of the roadbed slope 300, wherein the sound barrier columns 12 are arranged on one row of the foundations 3, and the photovoltaic columns 22 are arranged on the other row of the foundations 3. By burying a plurality of the foundations 3 on the roadbed slope 300, and connecting the sound barrier columns 12 and the photovoltaic columns 22 to each of the foundations 3, the sound barrier columns 12 and the photovoltaic columns 22 are more firmly fixed on the roadbed slope 300.

[0030] There is no restriction on the buried positions of the multiple foundations 3, as long as the sound barrier columns 12 and the photovoltaic columns 22 are installed on the roadbed slope 300 through the foundations 3. Preferably, in some embodiments, Figure 2As shown, the sound barrier columns 12 and the photovoltaic columns 22 are each provided with a plurality, and the plurality of foundations 3 are distributed in an array, and each of the foundations 3 is provided with the sound barrier columns 12 or the photovoltaic columns 22. By increasing the number of the sound barrier columns 12 and the photovoltaic columns 22, the sound barrier unit panels 11 and the photovoltaic unit panels 21 can be assembled and used by a plurality of smaller unit panels, which are more flexible in transportation and installation, and have lower production difficulty and cost compared to a whole unit panel. At the same time, the plurality of foundations 3 are distributed in an array, so that the four corners of the photovoltaic unit panels 21 are connected to the sound barrier columns 12 and the photovoltaic columns 22, and the connection is more firm.

[0031] Specifically, the distance between adjacent sound barrier columns 12 is set to 4m.

[0032] Since the noise of train running may affect the growth of plants on the roadbed slope 300, in some embodiments, such as Figure 1 As shown, the sound barrier column 12 is arranged on the foundation 3 near the side of the rail 200. In this way, the sound barrier column 12 reduces noise, ensures the normal growth of plants on the roadbed slope 300, and prevents workers from being affected by noise when installing and repairing the photovoltaic unit panel 21.

[0033] Furthermore, in some embodiments, Figure 1 As shown, the photovoltaic column 22 is provided with a mounting bracket 4 for installing communication cables and power cables. Compared with the existing communication cables and power cables buried under the roadbed slope 300 or arranged on the railway line, installing the communication cables and the power cables on the photovoltaic column 22 is more convenient for the maintenance and repair of the communication cables and the power cables, and there is no need to work on the railway line or dig the slope.

[0034] The specific manner in which the photovoltaic unit panels 21 are mounted on the sound barrier columns 12 and the photovoltaic columns 22 is not limited. For example, in some embodiments, Figure 2 As shown, the photovoltaic assembly 2 further includes a photovoltaic bracket 23, and the top of each sound barrier column 12 is connected to the top of the adjacent photovoltaic column 22 through the photovoltaic bracket 23, and the photovoltaic unit panel 21 is arranged in the photovoltaic bracket 23. In this arrangement, the sound barrier column 12 and the photovoltaic column 22 are connected through the photovoltaic bracket 23, and the photovoltaic unit panel 21 is framed, so that the installation of the photovoltaic unit panel 21 is more stable.

[0035] In addition, the present invention also provides a railway roadbed structure 1000, including a rail 200, two roadbed slopes 300, at least one contact network 400 and two photovoltaic sound barrier integrated systems 100, the two roadbed slopes 300 are respectively located on both sides of the rail 200, the two photovoltaic sound barrier integrated systems 100 are respectively arranged on the two roadbed slopes 300, and the contact network 400 is arranged between the photovoltaic sound barrier integrated system 100 and the rail 200.

[0036] In some embodiments, Figure 2 As shown, the railway roadbed structure 1000 also includes a maintenance walkway 500, which is laid on the roadbed slope 300 along the inclination direction of the roadbed slope 300. When the staff needs to work on the railway line, they can pass through the maintenance walkway 500 on the roadbed slope 300, through the photovoltaic sound barrier integrated system 100, and enter the line for maintenance.

[0037] In order to prevent rainwater from accumulating after rain, affecting the growth of plants on the roadbed slope 300 and reducing the stability of the roadbed slope 300, in some embodiments, as Figure 1 As shown, the railway roadbed structure 1000 further includes a drainage ditch 600, which is arranged on the side of the photovoltaic sound barrier integrated system 100 facing away from the rail 200. In this way, rainwater flows down along the slope of the roadbed slope 300 and is discharged from the drainage ditch 600, thereby preventing rainwater from accumulating and soaking the soil of the roadbed slope 300 for a long time, resulting in a decrease in the stability of the roadbed slope 300.

[0038] In order to prevent unauthorized persons from entering and affecting the normal operation of the photovoltaic sound barrier integrated system 100, Figure 1 As shown, the railway roadbed structure 1000 further includes a protective fence 700, which is arranged on the side of the drainage ditch 600 facing away from the photovoltaic sound barrier integrated system 100. The protective fence 700 is arranged to prevent unauthorized personnel from entering, so as to protect personnel safety.

[0039] In order to avoid water and soil erosion on the roadbed slope 300 when it rains, in some embodiments, Figure 1 As shown, shade-loving plants 800 are planted under the photovoltaic unit panel 21, and sun-loving plants 900 are planted on the side of the drainage ditch 600 facing away from the photovoltaic sound barrier integrated system 100. Since there is less sunlight under the photovoltaic unit panel 21, different plants can be planted according to local conditions, which can avoid soil erosion on the one hand, and construct an ecological photovoltaic sound barrier integrated system 100 on the other hand.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
