Abstract

The invention discloses a strong-wind-self-protecting indicating plate and a control method thereof. The indicating plate comprises an upright column, a cross rod, an indicating plate body, a wind force or air velocity transducer, a connecting mechanism, a flexible unlocking mechanism and a control system, wherein a supporting seat is arranged on the upright column, and a shaft sleeve rotatably sleeving the supporting seat is arranged on the cross rod; the connecting mechanism is arranged between the upright column and the cross rod and comprises a rigid connection state and a flexible connection state which can be mutually switched; the flexible unlocking mechanism acts under the control of the control system, and thus, the connecting mechanism can be switched between the rigid connectionstate and the flexible connection state; the control system receives signals from the wind force or air velocity transducer and sends instructions to the flexible unlocking mechanism. The indicatingplate disclosed by the invention can be switched between rigid connection and flexible connection, and flexible unlocking is carried out when air velocity reaches a threshold value, so that a strong-wind-self-protecting function is achieved.

Description

technical field

[0001] The present invention relates to the technical field of road traffic safety facilities, more specifically, to a road traffic sign capable of self-protection under strong wind conditions and a control method thereof. The present invention can also be applied to large billboards, road signs, road signs, tourist areas Signs, scenic spot signs, etc. Background technique

[0002] Road traffic signs play a key role in ensuring the unimpeded flow of urban traffic and the flow of people and vehicles in their own way. Therefore, the regular maintenance and physical examination of traffic signs is related to the interests of people's livelihood and travel safety, and it can see the degree of urban civilization to a certain extent. Strong winds, especially typhoons, are natural phenomena that coastal cities often face. Under the action of strong winds, road traffic signs are often deformed, damaged, rotated and misaligned, and even fall in severe cases, hinderin...
