Warning device for road construction

Abstract

The invention belongs to the technical field of road construction, and discloses a warning device for road construction. The warning device for the road construction comprises a solar panel, a warningpanel, a protective plate, a warning light, a supporting column and a base. One end of the solar panel is rotatably connected with the warning panel through a hinge, and LED lamps are arranged on theperiphery of the inner side of the warning panel. The warning device for the road construction can convert solar energy into electric energy to be stored in a storage battery by arranging the solar energy panel on the warning panel, and the use of components is facilitated; the warning panel is provided with a loudspeaker to play the content of road construction and remind pedestrians to be careful; a distance sensor and an infrared sensor are arranged at the lower end of the warning panel, and when people reach a set distance from a vehicle, an alarm is triggered; and the LED lamps are arranged on the periphery of the inner side of the warning panel, the work of the LED lamps can be controlled according to the light intensity, and the warning device is convenient to warn at night.

Description

technical field [0001] The invention relates to a warning device, in particular to a warning device for road construction, and belongs to the technical field of road construction. Background technique [0002] During the road construction process, relevant departments will place road construction signs on the construction site to remind passing pedestrians and vehicles. The warning signs in the prior art are generally non-retractable, their placement is relatively low, and the amount of information transmitted is limited. In many cases, it is difficult for people sitting in the car to observe, and they cannot play an obvious and effective warning role for the vehicle. The retractable warning sign is very complicated in structure, and it is inconvenient to store and arrange when not in use, and the volume is too large. The power supply display of the existing warning boards is usually troublesome and needs to be connected to a household power supply. Usually, it is difficult...

Problems solved by technology

The warning signs in the prior art are generally non-retractable, their placement is relatively low, and the amount of information transmitted is limited. Many times, it is difficult for people sitting in the car to observe, and they cannot play an obvious and effective warning role for the vehicle. The retractable warning sign is very complicated in structure, and it is inconvenient to store and arrange when not in use, and the volume is too large

The power supply display of the existing warning boards is usually troublesome and needs to be connected to a household power supply. Usually, it is difficult to meet a place with a home during road construction. The generator used for power generation is not only noisy, but also a waste of energy. For this reason, we propose A warning device for road construction
