Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warning devices, and specifically relates to a warning device for highways and bridges. BACKGROUND

[0002] With the development of economy, more and more attention is paid to the construction of highways and bridges. The construction of highways and bridges is crucial to the development of transportation and the growth of regional economy. It not only provides a convenient traffic channel, but also promotes the development of personnel flow, goods transportation and tourism. During the construction of highways and bridges, warning lights are needed to warn the construction area to avoid the influence of non-construction personnel entering by mistake. At the same time, it reminds the passing vehicles to slow down and pay attention to safety.

[0003] Chinese patent publication No. CN114395993A discloses a road and bridge construction warning device, which comprises a support rod, a plurality of support legs are fixedly installed at the bottom end of the support rod, a sliding rod is slidably installed in the support rod, a fixing assembly for fixing the sliding rod is arranged on the outer side of the support rod, a top plate is fixedly installed at the top of the sliding rod, a cavity is arranged in the top plate, a rotating rod is rotatably installed in the top wall of the top plate, and a lampshade is fixedly installed at the top of the rotating rod.

[0004] The above device cools the warning device through water circulation and the heat dissipation holes at the bottom, but in actual use, external air enters the lampshade through the heat dissipation holes. In spring and autumn, due to the large difference between day and night, the air near the ground cools down quickly, so the water vapor in the air near the ground easily condenses on the object to form water droplets. The air entering the lampshade also has water vapor condensation on the inner wall of the lampshade. If the water droplets on the inner wall of the lampshade are not cleaned, the light transmittance of the warning light bulb will be greatly reduced, and the warning effect will be poor.

[0005] Therefore, it is necessary to provide a warning device for highways and bridges to solve the above technical problems. SUMMARY
