Description

Technical Field

[0001] The present invention relates to the technical field of railway engineering, and in particular to an integrated photovoltaic sound barrier system and a railway roadbed structure. Background Art

[0002] Railway roadbed sound barriers are acoustic facilities installed between trains and sound-receiving points (such as nearby residential areas and schools). They effectively attenuate sound energy through acoustic effects such as reflection, absorption, and transmission, thereby reducing the propagation distance and intensity of noise and protecting the acoustic environment quality within 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 can easily 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 supports, 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 in the 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 the two 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 railway track.

[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 via the photovoltaic bracket, and the photovoltaic unit panel is arranged in the photovoltaic bracket.

[0012] In addition, the present invention also provides a railway roadbed structure, including rails, 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 rails, 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 rails.

[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.

[0014] According to some embodiments of the present invention, a drainage ditch is further included, and the drainage ditch is arranged on the side of the photovoltaic sound barrier integrated system facing away from the rail.

[0017] In the present invention, the sound barrier assembly includes a sound barrier unit panel and at least two sound barrier columns located on the roadbed slope, wherein the sound barrier unit panel is installed between the two sound barrier columns. The photovoltaic assembly includes a photovoltaic unit panel and a photovoltaic column located on the roadbed slope, wherein one end of the photovoltaic unit panel is mounted on the sound barrier assembly and the other end is supported by the photovoltaic column. Since the sound barrier unit panel is only connected to the side of the sound barrier column, while 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. Therefore, by sharing 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 other end of the photovoltaic unit panel can be supported by the photovoltaic column to achieve the installation of the photovoltaic unit panel.

[0026] The present invention provides a photovoltaic sound barrier integrated system and a railway subgrade structure. Figures 1 to 2 This invention provides a specific embodiment of an integrated photovoltaic sound barrier system and a railway subgrade structure.

[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 assembly 1 and a photovoltaic assembly 2, wherein 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, and 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.

[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 disposed on a roadbed slope 300. The sound barrier unit panel 11 is mounted between the two sound barrier columns 12. The photovoltaic assembly 2 includes a photovoltaic unit panel 21 and a photovoltaic column 22 disposed 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. Because the sound barrier unit panel 11 is only connected to the side of the sound barrier column 12, while the photovoltaic unit panel 21 is mounted on the top of each column, the sound barrier unit panel 11 and the photovoltaic unit panel 21 do not interfere with each other. Therefore, by sharing 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 other end of the photovoltaic unit panel 21 can be supported by the photovoltaic column 22 to achieve installation of the photovoltaic unit panel 21. This arrangement, by sharing the sound barrier assembly 1, can reduce the number of photovoltaic columns 22 and the footprint of the integrated photovoltaic and sound barrier system 100, thereby reducing the difficulty of slope support and improving the overall stability of the slope. The integrated photovoltaic and sound barrier system 100 and railway roadbed structure 1000 provided by the present invention solve the problems of difficult support and poor stability of existing railway roadbed slopes 300.

[0029] The sound barrier columns 12 and the photovoltaic columns 22 are both installed on the roadbed slope 300. The sound barrier unit panels 11 are installed on the sound barrier columns 12, and the photovoltaic unit panels 21 are mounted on the sound barrier columns 12 and the photovoltaic columns 22. In order to make the fixation of the sound barrier columns 12 and the photovoltaic columns 22 more secure and avoid the collapse of the two columns due to bad weather, which affects the normal use of the sound barrier unit panels 11 and the photovoltaic unit panels 21, in some embodiments, as Figure 1 As shown, the photovoltaic sound barrier integrated system 100 further includes two rows of foundations 3 embedded in the roadbed slope 300 at intervals along the inclination direction of the roadbed slope 300. One row of the foundations 3 is provided with the sound barrier columns 12, and the other row of the foundations 3 is provided with the photovoltaic columns 22. By embedding a plurality of the foundations 3 in 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 to 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, such as Figure 2As shown, there are multiple sound barrier columns 12 and photovoltaic columns 22, and the multiple foundations 3 are distributed in an array. Each of the foundations 3 is correspondingly provided with the sound barrier column 12 or the photovoltaic column 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 in conjunction with multiple smaller unit panels. Compared with a whole unit panel, transportation and installation are more flexible, and the production difficulty and cost are lower. At the same time, the multiple foundations 3 are distributed in an array, so that the four corners of the photovoltaic unit panels 21 are connected to each of 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 columns 12 are arranged on the foundation 3 on the side close to the rail 200. In this way, the sound barrier columns 12 reduce noise, ensure the normal growth of plants on the roadbed slope 300, and prevent workers from being affected by noise when installing and repairing the photovoltaic unit panels 21.

[0033] Furthermore, in some embodiments, Figure 1 As shown, the photovoltaic columns 22 are provided with mounting brackets 4 for installing communication cables and power cables. Compared to existing methods of burying communication cables and power cables under the roadbed slope 300 or installing them on the railway line, installing the communication cables and power cables on the photovoltaic columns 22 facilitates maintenance and repair of the communication cables and power cables, eliminating the need to work on the railway line or excavate 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, through which the top of each sound barrier column 12 is connected to the top of the adjacent photovoltaic column 22, and the photovoltaic unit panel 21 is arranged in the photovoltaic bracket 23. In this arrangement, the photovoltaic bracket 23 connects the sound barrier column 12 and the photovoltaic column 22 and frames the photovoltaic unit panel 21, making the installation of the photovoltaic unit panel 21 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, as Figure 2 As shown, the railway roadbed structure 1000 further includes an inspection walkway 500, which is laid on the roadbed slope 300 along the inclination direction of the roadbed slope 300. When workers need to work on the railway line, they can pass through the inspection walkway 500 on the roadbed slope 300, through the integrated photovoltaic sound barrier 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, such as Figure 1 As shown, the railway roadbed structure 1000 further includes a drainage ditch 600, which is provided on the side of the photovoltaic sound barrier integrated system 100 facing away from the rail 200. With this arrangement, rainwater flows down the slope of the roadbed slope 300 and is discharged from the drainage ditch 600, preventing rainwater from accumulating and soaking the soil of the roadbed slope 300 for a long time, which would reduce the stability of the roadbed slope 300.

[0038] In order to prevent the entry of irrelevant personnel and the influence of 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 provided on the side of the drainage ditch 600 facing away from the photovoltaic sound barrier integrated system 100. The protective fence 700 is provided to prevent unauthorized personnel from entering, thereby protecting 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 beneath the photovoltaic panels 21, and sun-loving plants 900 are planted on the side of the drainage ditch 600 facing away from the integrated photovoltaic and sound barrier system 100. Because there is less sunlight beneath the photovoltaic panels 21, different plants can be planted according to local conditions, thereby preventing soil erosion and creating an ecologically sound barrier integrated system 100.

[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 principles of the present invention should be included in the scope of protection of the present invention.
