Description

Technical Field

[0001] The utility model relates to the technical field of traffic control, in particular to an automatic flag-waving warning device. Background Art

[0002] In the daily maintenance and repair work of highways, manual flaggers are often required to wave flags in front of the construction site to warn moving vehicles and ensure the safety of moving vehicles as well as personnel and vehicles in the construction area. However, manual flagmen are in a relatively dangerous state during construction work, and they are prone to fatigue and cannot work continuously.

[0003] According to the search, the Chinese patent document, authorization announcement number CN210797336U, discloses an automatic flag-waving warning device for highway traffic control. The device performs traffic control by waving flags automatically, thereby replacing manual waving of flags and reducing people's labor intensity. The solar panels are used to power the batteries and motors, which can not only improve the endurance of the device, but also make full use of solar energy to achieve energy conservation and emission reduction. The warning ability at night can be effectively improved by setting warning lights, light strips and reflective tapes. However, the device is not only inconvenient to move, but also unable to adjust the height or angle of the device body. Moreover, the flag in the device body swings up and down with a small swing amplitude, which cannot play a good warning role, reducing the applicability of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

The motor drives the rotating shaft 1 to rotate, and the rotation of the rotating shaft 1 drives the half gear to rotate. When the half gear rotates to mesh with the gear 2, the half gear drives the gear 2 to rotate, and the rotation of the gear 2 drives the rotating shaft 2 to rotate in the positive and negative directions, thereby driving the flag to swing regularly in the left and right directions, so as to use the flag to warn the vehicle.

[0021] 2. The utility model can move the adjusting rod by loosening the locking bolt. After adjusting the adjusting rod to a suitable height, the locking bolt can be tightened again to fix the adjusting rod. When it is necessary to adjust the angle of the flag, pull the pull rod to the right, and the pull rod drives the rack away from gear one. At this time, the turntable can be rotated, and the rotation of the turntable drives the base rod to rotate. The rotation of the base rod drives the flag to rotate to a suitable angle, and then the pull rod is loosened, and the rack moves toward gear one under the push of the spring, so that gear one can be limited by the rack.
