Description
Technical Field
[0001] This utility model relates to the field of highway guardrail technology, specifically a dustproof and self-cleaning guardrail for highways. Background Technology
[0002] Highway guardrails, also known as crash barriers or safety barriers, are important traffic safety facilities installed on both sides of highways, in the median strip, and on dangerous sections of bridges. When a vehicle loses control or collides with another vehicle, the guardrail prevents it from veering off the road, falling off cliffs, entering oncoming lanes, or hitting roadside obstacles, thus reducing the severity of the accident. Furthermore, through their structural design, guardrails absorb some of the impact energy, mitigating vehicle damage and personal injury. At the same time, guardrails provide drivers with clear driving boundaries, helping them maintain the correct driving line, especially on curves, slopes, or sections with poor visibility.
[0003] However, highway guardrails require regular manual cleaning, which is costly in terms of both cleaning and labor, leaving room for improvement. Utility Model Content
[0004] The purpose of this utility model is to provide a dustproof self-cleaning guardrail for highways to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof self-cleaning guardrail for highways, including a guardrail mounting base, an inner fold of the guardrail inside the guardrail mounting base, a drainage pipe on one side of the guardrail mounting base, the end of the drainage pipe away from the guardrail mounting base communicating with the inner fold of the guardrail, a pneumatic plate movably connected to one side of the inner fold of the guardrail, and a movable included angle between the pneumatic plate and the inner fold of the guardrail.
[0006] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein a drainage slope is fixedly connected to one side of the guardrail mounting base, and both the guardrail mounting base and the drainage slope are fixedly connected to an external guardrail bracket.
[0007] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein the end of the drainage pipe that is inserted into the guardrail and folded inside is provided with a cleaning hole, and the distance between the cleaning hole and the pneumatic plate is 1-2cm.
[0008] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein a drainage groove and a drainage hole are provided on one side of the guardrail mounting base, and the drainage hole is connected to a drainage pipe.
[0009] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein the inside of the drainage channel is provided with a slope, the inside of the drainage hole is provided with a large opening and a stepped opening, the stepped opening is connected to the drainage pipe, and the slope is flush with the stepped opening.
[0010] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein the guardrail has a slot inside the inward fold, a movable ball is fixedly connected to one side of the pneumatic plate, the distance between the pneumatic plate and the inward fold of the guardrail is 0.5-1cm, and the movable ball is movably connected to the slot.
[0011] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein both sides of the wind-driven plate are polished.
[0012] As a further embodiment of this utility model: a dustproof self-cleaning guardrail for highways, wherein the included angle of the movable angle is 12-18°.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Because the guardrail mounting base has an inner fold inside, and a drainage pipe is provided on one side of the guardrail mounting base, the end of the drainage pipe away from the guardrail mounting base is connected to the inner fold of the guardrail. A pneumatic plate is movably connected to one side of the inner fold of the guardrail. A movable angle is formed between the pneumatic plate and the inner fold of the guardrail, and the included angle is 12-18°. Therefore, on the one hand, rainwater can fall into the inner fold of the guardrail through the drainage pipe and clean the inner fold of the guardrail, which can avoid the problem of dirt remaining in the embedded inner fold of the guardrail. On the other hand, the movable pneumatic plate can flash and accelerate the airflow in the inner fold of the guardrail, which can clean dry dust and keep the inner fold of the guardrail clean.
[0015] 2. Because a drainage slope is fixedly connected to one side of the guardrail mounting base, and both the guardrail mounting base and the drainage slope are fixedly connected to the external guardrail bracket, and a drainage groove and a drainage hole are opened on one side of the guardrail mounting base, the drainage hole is connected to the drainage pipe, the drainage groove has a slope inside, the drainage hole has a large opening and a stepped opening inside, the stepped opening is connected to the drainage pipe, and the slope is flush with the stepped opening, so rainwater can be smoothly guided from the drainage slope into the guardrail mounting base, and then discharged from the inside of the guardrail to clean the guardrail.
