Description

Technical Field

[0001] The utility model relates to the field of viaduct lighting, in particular to a viaduct lighting system. Background Art

[0002] For both aesthetics and safety, existing elevated bridges typically require the installation of lighting fixtures such as wall washers, outline lights, and color-changing light guides. These are all symmetrically installed around the outer edge of the elevated bridge. For example, patent CN 201819164 U discloses an anti-glare elevated bridge mounting structure for LED wall washers. The mounting bracket is bolted to the underside of the elevated bridge near the outer edge. The bracket features an LED wall washer mounting plate with an outer end extending obliquely inward and downward. The LED wall washer mounting plate is mounted on a slightly upward-facing LED wall washer, reflecting light asymmetrically from the LED light source. This makes the LED light largely invisible to drivers traveling under the elevated bridge, improving safety.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] In order to solve the technical problem that there are generally a large number of lighting equipment installed on the outer edge of the viaduct, the huge lighting facilities will cause complicated and crowded wiring on the outer edge of the viaduct, and there is an urgent need for an viaduct lighting system that can make the wiring beautiful and simple. The utility model provides an viaduct lighting system, which can make the wiring on the outer edge of the viaduct beautiful and simple, thereby improving the aesthetics of the viaduct.

[0032] See also Figures 1 to 4 , Figures 1 to 4 This is a structural schematic diagram of an elevated bridge lighting system in one embodiment of the present invention, wherein the elevated bridge lighting system includes a drainage pipe 2, a pre-buried pipe 3 and a plurality of lighting components; and the elevated bridge 1 includes a bridge body 11 and a guardrail 12, the guardrail 12 being connected to the upper end surface of the bridge body 11; the drainage pipe 2 has a drainage channel 2a and is used to be buried in the guardrail 12 of the elevated bridge 1; the pre-buried pipe 3 is buried in the guardrail 12 and includes a main pipe 31 and a plurality of branch pipes 32, the main pipe 31 is placed on the upper side of the drainage pipe 2, and a drainage outlet 31a connected to the drainage channel 2a is provided at the bottom thereof, one end of each branch pipe 32 is connected to the main pipe 31, and the other end extends to the outer wall of the guardrail 12; a plurality of lighting components 4 are installed on the outer wall of the guardrail 12, and the electrical connection parts 41 of the plurality of lighting components 4 are respectively placed at the end of the plurality of branch pipes 32 away from the main pipe 31.

[0033] In the viaduct lighting system provided by the present invention, when manufacturing the prefabricated box girder of the viaduct 1, the cables connecting the electrical connection to the lighting equipment can be first placed in the main pipe 31 and the branch pipe 32, and then the drainage pipe 2, the main pipe 31, and the branch pipe 32 can be buried in the guardrail 12 of the viaduct 1. This prevents the cables from accumulating on the outer edge of the guardrail 12 and affecting its appearance. It also protects the cables from wind and rain erosion by the pre-buried pipe 3, thereby extending their service life. Simultaneously, the condensed liquid droplets in the main pipe 31 can be drained through the drainage port 31a into the drainage channel 2a of the drainage pipe 2 and discharged externally, preventing water accumulation in the main pipe 31 and causing safety hazards, thereby improving safety performance. Thus, this solution can make the wiring on the outer edge of the viaduct 1 beautiful and simple, improving the aesthetics of the viaduct 1, while also extending the service life of the lighting equipment and improving safety performance.

[0034] In one embodiment, see Figure 5 and Figure 6The drainage channel 2a and main pipe 31 are arranged along the extension direction of the guardrail 12 and penetrate the guardrail 12. Multiple branch pipes 32 are connected to the main pipe 31 at intervals along the extension direction of the guardrail 12. The drainage pipe 2 is open at the top, and the drainage port 31a is located at the bottom of the main pipe 31. The main pipe 31 is mounted on the opening of the drainage pipe 2, so that the drainage port 31a connects to the drainage channel 2a. In addition, the bottom of the main pipe 31 is provided with multiple drainage ports 31a, which are spaced apart along the extension direction of the bridge body 11.

[0035] In this embodiment, the main pipe 31 is mounted above the drain pipe 2, making the structure more compact, reducing the space occupied by the pipe body on the guardrail 12, and improving the strength of the guardrail 12. Furthermore, the main pipe 31 is arranged along the extension direction of the guardrail 12, and multiple branch pipes 32 are connected to the main pipe 31 at intervals along the extension direction of the guardrail 12. This allows multiple sets of lighting assemblies 4 to be arranged accordingly along the extension direction of the guardrail 12, making the layout of the lighting assemblies 4 more reasonable and aesthetically pleasing. Specifically, in this embodiment, the drain pipe 2 is tilted downward from the middle to both ends. This allows droplets in the drainage channel 2a to be discharged along the inclined direction of the drainage channel 2a, further preventing water accumulation and improving safety.

[0036] In one embodiment, the viaduct lighting system also includes a support frame 5, each support frame 5 includes a support plate 51 and two connecting plates 52, the two connecting plates 52 are respectively connected to the two ends of the support plate 51, and the bottom ends are fixed to the bottom wall of the drainage channel 2a, and the support plate 51 is supported by the main pipe 31.

[0037] In this embodiment, since the main pipe 31 is relatively long, brackets are used to support it in the guardrail 12 to ensure stability during installation. This prevents it from falling into the drainage channel 2a in the unlikely event of a fall. Specifically, multiple support brackets 5 are provided, spaced apart along the extension of the main pipe 31, ensuring effective support for the main pipe 31 throughout its entire length. Furthermore, in this embodiment, the diameter of the drainage channel 2a is smaller than that of the main pipe 31. This allows the main pipe 31 to be supported by the inner wall of the drainage channel 2a, further enhancing its installation stability.

[0038] In one embodiment, see Figure 5 The embedded pipe 3 further includes a partition net 33 , which divides the inner cavity of the main pipe 31 into two chambers along the vertical direction, and each branch pipe 32 is connected to the chamber on the upper side.

[0039] In this embodiment, the inner cavity of the main pipe 31 is divided into two chambers by a partitioning net 33. This allows the upper chamber to be used as space for cable routing. This prevents water from accumulating in the lower chamber and directly contacting the cables if the drain outlet 31a becomes clogged, further improving safety. Furthermore, each branch pipe 32 is arranged to slope downward from the end connected to the main pipe 31 to the end away from the main pipe 31. This allows water to be diverted and discharged from the main pipe 31 through the branch pipe 32 in the event of water unexpectedly accumulating in the chamber of the main pipe 31, accelerating the drainage rate of the main pipe 31.

[0040] In one embodiment, see Figure 3 and Figure 4 The lighting assembly 4 includes a switch power box 42 and multiple light boxes 43 installed on the outer wall of the guardrail 12. The switch power box 42 is located at the end of the corresponding branch pipe 32 away from the main pipe 31 and is electrically connected to the multiple light boxes 43. The multiple light boxes 43 are arranged at intervals along the extension direction of the guardrail 12, wherein the switch power box 42 is the electrical connection part 41.

[0041] In this embodiment, a switch power box 42 is first electrically connected to the cable extending from the branch pipe 32, and then electrically connected to multiple light boxes 43 in the same group. The switch power box 42 controls the opening and closing of multiple light boxes 43 in the same group, allowing multiple groups of lighting assemblies 4 to be connected in parallel to the main cable, improving lighting stability. In addition, in this embodiment, the light boxes 43 have LED color-changing light guide plates.

[0042] In one embodiment, the lighting assembly 4 further includes a wire trough 44 , which is installed on the outer wall of the guardrail 12 and arranged along the extension direction of the guardrail 12 , and the connecting wires between the switch power box 42 and each light box 43 are built into the wire trough 44 .

[0043] In this embodiment, the connecting cables between the switch power box 42 and the light box 43 are also placed in the wire duct 44 to prevent the connecting cables from being directly exposed to the outside and affecting the aesthetics. Specifically, the lighting assembly 4 also includes a contour light 45. The contour light 45 is installed on the side of the wire duct 44 away from the guardrail 12, and is arranged along the extension direction of the guardrail 12, and is electrically connected to the switch power box 42. In this way, the contour light 45 can be used to block the wire duct 44 to improve the aesthetics. At the same time, the wires between the contour light 45 and the switch power box 42 can be built into the wire duct 44 to avoid the cables from being exposed and improve the space utilization outside the guardrail 12. It should be noted that in this embodiment, the contour light 45 is an LED contour light. In addition, in one embodiment, a two-way wall lamp is also provided on the support column 13 of the viaduct 1, and a glass fiber reinforced plastic pipe corresponding to the two-way wall lamp is buried in the support column 13 for wiring.

[0044] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0045] When fabricating the prefabricated box girders of viaduct 1, the cables connecting the electrical connections to the lighting equipment can be placed first in main pipe 31 and branch pipe 32. Drain pipe 2, main pipe 31, and branch pipe 32 are then buried in guardrail 12 of viaduct 1. Condensed droplets of steam and water in main pipe 31 enter drainage channel 2a through drain port 31a and are discharged along the slope of drainage channel 2a, preventing water accumulation and improving safety. Furthermore, the pre-buried pipe 3 protects the cables from wind and rain erosion, extending their service life. This results in beautiful and concise wiring along the outer edge of viaduct 1, enhancing its aesthetic appeal.

[0046] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
