Description

Technical Field

[0001] This utility model relates to the field of protective fencing technology, specifically, to a protective fencing for municipal engineering construction. Background Technology

[0002] Due to tight schedules and fluctuating traffic flow, nighttime construction is a common occurrence in municipal engineering projects. Ensuring the clear visibility of protective fencing around construction areas in low-light conditions at night is crucial for the safety of pedestrians and vehicles.

[0003] Currently, the industry commonly uses reflective strips affixed to the exterior of protective fencing as nighttime warning signs. However, this traditional approach has significant limitations. Reflective strips rely on external light sources for their effectiveness; they only produce good reflectivity and attract the attention of pedestrians and vehicles when there is sufficient light and the angle of illumination is appropriate. If the external light source is insufficient, such as in dimly lit areas or when the light source is not at a good angle, the reflective effect of the strips is greatly reduced, making it difficult to provide an effective warning.

[0004] In summary, existing protective fencing warning methods based on reflective strips have many shortcomings in practical applications. There is an urgent need for a more reliable, efficient, and nighttime-adaptable protective fencing design to improve the safety of municipal engineering construction at night and ensure the safety of pedestrians and vehicles. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes a protective fence for municipal engineering construction.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A protective fence for municipal engineering construction includes a fence body with a light-transmitting hole and a focusing lens inside the light-transmitting hole; the outer surface of the focusing lens away from the construction area is flush with the outer surface of the fence body, and its inner surface near the construction area protrudes towards the construction area.

[0008] During nighttime construction of municipal engineering projects, various lighting devices are typically installed within the construction area to illuminate the work zone. The light-transmitting openings in the main body of the construction site fence, along with the focusing lenses embedded within them, capture light rays radiating from the construction area towards the fence. Because the inner surface of the focusing lens near the construction area bulges towards that area, this unique curved design, similar to a convex lens, helps collect and initially converge light rays from various angles within the construction area. This allows the focused light to propagate in a relatively concentrated manner to the outside space of the fence. In this way, the originally dispersed light rays within the construction area, through the action of the focusing lens, form a relatively bright and directional beam outside the fence, thereby enhancing the fence's visibility at night and making it easier for pedestrians and vehicles to notice it.

[0009] Compared to traditional protective barriers that rely solely on reflective strips, the use of focusing lenses to collect, focus, and propagate light within the construction area significantly improves the barrier's visibility at night.

[0010] Preferably, it also includes a silicone sealing ring, with an annular groove provided on the inner side of the light-transmitting hole, and an annular sealing gasket provided on the outer wall of the silicone sealing ring that can be inserted into the annular groove. The condensing lens is embedded in the light-transmitting hole through the silicone sealing ring.

[0011] The annular groove inside the light-transmitting hole engages with the annular sealing gasket on the outer wall of the silicone sealing ring. During installation, align the annular sealing gasket on the silicone sealing ring with the annular groove in the light-transmitting hole, then press the silicone sealing ring firmly in, ensuring the annular sealing gasket is tightly fitted into the annular groove, thus securely installing the silicone sealing ring inside the light-transmitting hole.

[0012] The condensing lens is embedded in the light-transmitting hole through a silicone sealing ring. Because silicone itself has good elasticity and flexibility, when the condensing lens is placed inside the silicone sealing ring, the ring will tightly wrap around the lens, providing stable support and fixation. This ensures that the condensing lens will not shake or fall off during the use of the enclosure, and will always remain in the correct position to guarantee the normal functioning of its focusing and transmission capabilities.

[0013] Preferably, the light-transmitting holes are provided in multiple sizes and are evenly distributed around the perimeter of the main body of the enclosure.

[0014] Multiple light-transmitting holes are evenly distributed around the perimeter of the main structure of the construction site. Light from inside the construction area passes through focusing lenses within these holes, creating a continuous and relatively uniform light outline around the perimeter of the site. This light outline corresponds to the actual boundaries of the site, thus delineating its boundaries. At night, pedestrians and vehicles can clearly discern the shape and boundaries of the site using this light, accurately determine the extent of the construction area, and clearly understand the boundary between passable space and hazardous areas.

[0015] Preferably, the light-transmitting holes are provided in multiple locations and are evenly distributed in the upper area of ​​the side wall of the main body of the enclosure.

[0016] Multiple light-transmitting holes are evenly distributed in the upper part of the main side wall of the construction site. When light from inside the construction area passes through the focusing lenses within these holes, it forms a relatively continuous light band on the outside of the construction site. This light band extends along the upper part of the side wall of the construction site, and its length corresponds to the width of the construction site. Because the start and end points of the light band are clearly defined, pedestrians and vehicles can visually judge the width of the construction site by observing the length of the light band, thus accurately perceiving the horizontal space occupied by the construction area. At the same time, the high placement of the light-transmitting holes effectively reduces dust contamination of the focusing lenses.

[0017] Preferably, the outer wall of the enclosure body is provided with an annular boss, the axis of the annular boss is coaxial with the light-transmitting hole, and the side of the annular boss near the light-transmitting hole is set as an inclined surface.

[0018] The annular protrusions surrounding the light-transmitting holes form a physical barrier to some extent. When external dust approaches the light-transmitting holes, it is blocked by the annular protrusions, reducing the possibility of dust directly entering the holes and contaminating the condensing lens. This provides additional protection for the condensing lens. The reflection effect of the annular protrusions' inclined surfaces enhances the visual effect of the condensing lens, making the main structure of the enclosure clearer at night.

[0019] Preferably, a reflective sticker is fixed on the inclined surface.

[0020] When light shines from the condenser lens and is reflected by the inclined surface of the annular boss, the reflective stickers fixed on the inclined surface reflect these reflected rays again. The reflective stickers have a high reflectivity, efficiently reflecting the light that hits them, further enhancing the intensity and scattering range of the light. This makes the warning light emitted from the fence brighter and more conspicuous in all directions, making it easier for pedestrians and vehicles to notice, even in low-light conditions.

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0029] Example 1

[0030] The protective fence for municipal engineering construction in this embodiment includes a fence body 110. The fence body 110 has multiple light-transmitting holes 1101, which are evenly distributed around the perimeter of the fence body 110.

[0031] Each light-transmitting hole 1101 is equipped with a condensing lens 120. The outer surface of the condensing lens 120 away from the construction area is flush with the outer surface of the main body of the enclosure 110, while the inner surface near the construction area protrudes towards the construction area. An annular groove 1102 is provided inside the light-transmitting hole 1101, and a silicone sealing ring 130 is also provided. An annular sealing gasket 1301 is provided on the outer wall of the silicone sealing ring 130, which can be inserted into the annular groove 1102. The condensing lens 120 is embedded in the light-transmitting hole 1101 through the silicone sealing ring 130.

[0032] In addition, an annular boss 140 is provided on the outer wall of the main body 110 of the enclosure for each light-transmitting hole 1101. The axis of the annular boss 140 is coaxial with the light-transmitting hole 1101. The side of the annular boss 140 near the light-transmitting hole 1101 is set as a slope 1401, and a reflective sticker is fixed on the slope 1401.

[0033] Its specific operating principle is as follows: During nighttime construction of municipal engineering projects, lighting equipment is used within the construction area as needed. The light emitted by this equipment diffuses in all directions. The focusing lens 120 inside the light-transmitting hole 1101 at the perimeter of the main body of the enclosure 110 collects light from various angles of the construction area using its convex inner surface, similar to a convex lens, and initially converges it, allowing the light to propagate to the outside of the enclosure in a relatively concentrated manner. After the light is emitted, it first illuminates the inclined surface 1401 of the annular boss 140. The reflection by the inclined surface 1401 changes the direction of propagation, achieving wider scattering. At this time, the reflective sticker on the inclined surface 1401 reflects the reflected light again, further enhancing the light intensity and scattering range. The collection and focusing of light by the focusing lens 120, combined with the multiple reflections of light by the inclined surface 1401 of the annular boss 140 and the reflective sticker, significantly improves the visibility of the enclosure in all directions at night, allowing pedestrians and vehicles to be clearly identified from a distance.

[0034] Meanwhile, the silicone sealing ring 130 is securely installed inside the light-transmitting hole 1101 through a tight fit between the annular sealing gasket 1301 and the annular groove 1102 on the inner side of the light-transmitting hole 1101. It also tightly wraps around the condensing lens 120 with its own elasticity, ensuring the condensing lens 120 remains in a stable position and performs its light-concentrating and light-transmitting functions normally. The light-transmitting holes 1101, evenly distributed along the perimeter of the main body of the enclosure 110, form a continuous light outline that matches the actual boundary of the enclosure. This helps pedestrians and vehicles clearly identify the shape and boundaries of the enclosure, accurately determine the construction area, and clearly define the boundaries between passable and hazardous areas, ensuring safe passage.

[0035] Example 2

[0036] Compared to Embodiment 1, the difference is that multiple light-transmitting holes 1101 are provided and are evenly distributed in the upper area of ​​the side wall of the enclosure body 110.

[0037] The light-transmitting hole 1101 is located in the upper part of the side wall of the enclosure body 110. By utilizing the distribution characteristics of dust in the air, it effectively reduces the contamination of the condensing lens 120 by dust, further extends the time that the condensing lens 120 remains clean, maintains its good light-concentrating and light-transmitting performance, and reduces the frequency of maintenance.

[0038] Multiple light-transmitting holes 1101 form a continuous light strip in the upper area of ​​the side wall of the fence. The length of the light strip corresponds to the width of the fence. Pedestrians and vehicles can intuitively judge the width of the fence through the light strip, more accurately perceive the space occupied by the construction area laterally, plan a safe passage path in advance, and avoid danger caused by misjudging the width.

[0039] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
