Description

Technical Field

[0001] This utility model relates to the field of warning guardrails, and more particularly to warning guardrails for municipal engineering. Background Technology

[0002] In municipal engineering construction, warning guardrails must be placed at construction sites to alert pedestrians and vehicles. These guardrails mainly serve to isolate dangerous areas, prevent vehicles from running off the road, improve road safety, provide isolation, obstruction, and warning functions. Conventional guardrails are mostly temporary and need to be removed after construction is completed, so the design should take into account ease of movement and dismantling.

[0003] Existing warning barriers used in municipal engineering projects are mostly of fixed height, which only needs to achieve isolation and cannot be adjusted in height, thus having certain limitations. In addition, in order to make it easier for people to see the barriers at night, reflective strips are attached to increase the warning effect, but reflection requires a light source, resulting in limited warning effect and low practicality.

[0004] Therefore, in view of the problems mentioned above, such as the inability to adjust the height of existing warning guardrails for municipal engineering and the need for a light source for reflection, resulting in limited warning effect, it is possible to design warning guardrails for municipal engineering that allow for easy adjustment of the lighting range and the addition of cleaning components to clean the surface of the transparent glass cover, reducing the obstruction of the glass surface by dust. Utility Model Content

[0005] In order to overcome the problems of existing warning guardrails used in municipal engineering projects, such as the inability to adjust the height and the need for a light source for reflection, resulting in limited warning effect.

The posts 1 are evenly spaced, and the surface of the fixing plate 1 is provided with identical flashing lights, which are also evenly spaced.

[0008] The movable guardrail includes two posts. A connecting plate is fixedly installed at the upper end of the two posts, and a movable plate is fixedly connected to the lower end of the two posts. The two posts are evenly distributed, and the two posts and the first post are distributed in an alternating manner.

[0009] Preferably, the overall guardrail consists of fixed guardrails and movable guardrails, which facilitates height adjustment, increases flexibility, and achieves self-illuminating warning through flashing lights, thereby improving the warning effect.

[0017] 1. The warning guardrail used in this municipal engineering project is adapted to use a top photovoltaic panel and a storage battery. During the day, the photovoltaic panel converts solar energy and powers the storage battery, which in turn powers the flashing lights at night. The flashing lights at night increase the warning effect of the guardrail. At the same time, the height of the movable guardrail can be adjusted to change the overall height of the guardrail and increase its flexibility.

Mounting posts 21 are fixedly connected to both sides of the upper surface of the anti-slip seat 2. Through holes are opened on the surface of the counterweights 3, and the through holes are fitted with the mounting posts 21. Fixed posts 4 are fixedly connected to the left and right sides of the upper end of the mounting base 1, with the two fixed posts 4 positioned between each other. A fixed guardrail is provided, and a movable guardrail is provided within the fixed guardrail. A movable column 5 is sleeved on the upper end of the fixed column 4. A top seat is fixedly installed on the upper end of the movable column 5. A photovoltaic panel 6 is installed on the upper end of the top seat through a mounting bracket. A limit component is provided on the front end face of the fixed column 4. A flashing light 13 is provided on the surface of the fixed column 4. A storage battery is provided in the mounting base 1. The storage battery and the photovoltaic panel 6 are electrically connected. The flashing light 13 is electrically connected to the storage battery. The flashing light 13 realizes self-illuminating warning, which improves the warning effect.

[0028] The fixed guardrail includes a post 7, with a fixing plate 8 and a fixing plate 9 fixedly connected to the upper and lower ends of the post 7 respectively. The posts 7 are evenly spaced, and the surface of the fixing plate 8 is provided with identical flashing lights 13, which are also evenly spaced.

[0029] The movable guardrail includes two posts 10, with a connecting plate 11 fixedly installed at the upper end of each post 10 and a movable plate 12 fixedly connected to the lower end of each post 10. The posts 10 are evenly spaced and are staggered with the posts 17. By adjusting the position of the connecting plate 11, the posts 10 drive the movable plate 12 to move synchronously, thereby adjusting the height of the guardrail.

[0030] Please see Figure 1 , Figure 5 and Figure 6 In this embodiment, the limiting component includes a pin rod 41. A pin hole is provided on the surface of the fixed column 4. The pin hole and the pin rod 41 are slidably connected. One end of the pin rod 41 extends to the outside of the fixed column 4 and a top block 42 is fixedly installed thereon. A spring 43 is sleeved on the outside of the pin rod 41. The two ends of the spring 43 are fixedly connected to the fixed column 4 and the top block 42, respectively. Limiting holes 44 are provided on the surface of the movable column 5. The limiting holes 44 are evenly distributed. The other end of the pin rod 41 is pinned to the limiting hole 44. When the movable column 5 is moved, the top block 42 is pulled first to move the pin rod 41 and disengage it from the limiting hole 44. After the movable column 5 is adjusted, the top block 42 is released, and the spring 43 drives the pin rod 41 to reset and re-insert it into the limiting hole 44 to achieve limiting.

[0031] Please see Figure 2 , Figure 4 and Figure 5 In this embodiment, the surface of the fixed plate 8 is provided with a sleeve hole 81. The fixed plate 8 is slidably connected to the column 10 through the sleeve hole 81. Both ends of the fixed plate 8 and the fixed plate 9 are fixedly connected to the fixed column 4. Both ends of the connecting plate 11 are fixedly connected to the top seat. The surface of the movable plate 12 is provided with the same sleeve hole 81. The column 7 and the column 10 are the same size. The movable plate 12 is slidably connected to the column 7 through the sleeve hole 81. When the movable column 5 moves, it drives the connecting plate 11 to move upward. The column 10 drives the movable plate 12 to move synchronously. The column 10 moves on the fixed plate 8, and the movable plate 12 moves on the column 7. The fixed guardrail and the movable guardrail are staggered, and the height of the guardrail is adjusted.

[0032] During operation, the guardrail is placed in a suitable position, with the anti-slip seat 2 in contact with the ground. The configuration block is installed on the anti-slip seat 2 to increase stability. The top photovoltaic panel 6 can convert solar energy during the day to power the battery. At night, the battery powers the flashing light 13, which illuminates at night, ensuring the warning effect of the guardrail. Simultaneously, the movable column 5 can be moved upward, driving the connecting plate 11 upward. The second column 10 drives the movable plate 12 to move synchronously. The second column 10 moves on the first fixed plate 8, and the movable plate 12 moves on the first column 7. The fixed guardrail and the movable guardrail are staggered, and the height of the guardrail is adjusted. After adjustment, the spring 43 drives the pin rod 41 to reset and re-insert it into the limiting hole 44 to achieve the limiting.

[0033] Through the above steps, the overall guardrail consists of fixed guardrails and movable guardrails, which facilitates height adjustment, increases flexibility, and achieves self-illuminating warning through flashing lights 13, thereby improving the warning effect. This solves the problem that existing warning guardrails used in municipal engineering cannot be adjusted in height and require a light source for reflection, resulting in limited warning effect.
