Strong-wind-self-protecting indicating plate and control method thereof

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...

AI Technical Summary

Problems solved by technology

[0008] Comparing the above three types: the reinforcement column type protection method is simple and reliable, but it is only a passive reinforcement column, which does not reduce the resistance of the signage. If it is popularized in a large area, it will require huge manpower and materials, and the cost is high; ventilation slots Ventilated traffic signs reduce the windward area to a certain extent, thereby reducing the resistance on the sign board, but the area that can be used for ventilation slots is limited, which will make the writing on the signs unclear, and the ventilation slots are susceptible to damage. Blocked by other sundries; the sensor passive control mode in the indicator board control type can realize the control of the angle of the indicator rod according to the wind force classification, so as to adjust the area facing the wind of the indicator board and reduce the strong wind resistance, but the angle of the indicator board is rigidly connected before and after adjustment. Generally, it is more applicable to the situation where the indicator board is adjusted around the horizontal axis. If it is adjusted around the vertical axis, there will still be a situation where the indicator board cannot adapt to the wind direction and cause excessive resistance and damage; If the parts are connected flexibly, there will be a problem of random swing of the indicator board due to excessive gusts, and this kind of structure needs a reset device, which generally uses gravity reset or elastic reset, and a large swing force or reset force is not only It will cause damage to the sign itself, and it will also cause damage to the surrounding environment such as external trees, houses, and wires.

[0009] In short, there are very few inventions in this area of ​​strong wind self-protection signs after retrieval, and the existing inventions have single functions, low safety, and applicability to be improved
