a limiting rotation mechanism is arranged between the connecting frame 12 and the rotating arc surface 512, the limiting rotation mechanism 53 comprises a T-shaped limiting groove 531 arranged on the rotating arc surface 512, a T-shaped sliding block is arranged on the connecting seat 121 in a manner of matching with the T-shaped limiting groove 531, the moving track of the T-shaped limiting groove 531 and the rotating arc surface 512 are arranged to be concentric circles, namely, the inner wall of one side, facing the rotating arc surface 512, of the T-shaped limiting groove 531 is an arc surface concentric with the rotating arc surface 512;

when warning tablet board 22 receives the wind and takes place to empty, the main reason is because whole warning device's focus is on the high side, consequently because the setting of counter weight storehouse 527 among the central balance mechanism, in the actual work process, after the staff accomplishes strut subassembly 4's fixed, the staff both can add the counter weight medium to counter weight storehouse 527 through counter weight door 528, after the counter weight medium adds, whole warning device's focus can descend owing to the influence of additional counter weight medium this moment, make whole warning device's center on the low side, thereby make wind be difficult for blowing whole warning device to, after accomplishing the counter weight medium and adding promptly, whole warning device self has certain anti-wind ability promptly.

When the wind force is increased, the wind force acts on the warning board plate 22, the warning board plate 22 drives the positioning rack 11 to rotate along the rotating arc surface 512, at this time, the unlocking pendulum 513 moves towards the side opposite to the moving direction of the positioning rack 11 under the driving of the positioning rack 11, so that the end of the unlocking pendulum 513 abuts against and pushes the guide rod 516 in the moving direction, then the guide rod 516 rotates along the support shaft, so that the lock hook 517 disengages from the lock hook groove 515, at this time, under the action of the tension spring 524322, the connecting seat 121 on the side coming to the wind drives the strut assembly 4 to lift up, the originally offset 521 is in the same vertical direction as the strut assembly 4, at this time, the unlocking box 511 moves towards one side of the unlocking box 511 along the reset arc surface 523 under the action of gravity, so that the gravity of the originally offset 521 acting on the strut assembly 4 part generates offset towards the direction of lifting up the strut assembly 4, at this time, the center of the whole warning device will deviate towards one side of the connection seat 121 which is not lifted, but the whole device will not fall towards one side which is not lifted, at this time, under the action of the tension spring 524322, the lifted connection seat 121 drives the strut component 4 to move, so that the strut component 4 is lifted, meanwhile, under the action of the limiting rotating mechanism, the connection seat 121 will not rotate after the connection seat 121 does not break away from the rotating arc surface 512 and rotates to the maximum angle, the weight in the weight cabin 527 in the lifted strut component 4 is not rotated, in this embodiment, sand is adopted, granular solid weight media such as a small ball and a stone can also be adopted, liquid media such as water and oil can also be adopted, most of the weight of the sand can be pressed on the magnetic attraction door, the magnetic attraction door breaks away from the weight cabin 527 under the action of self gravity and the pressing of the sand, so that the sand in the weight cabin 527 falls down from the weight cabin 527, sand can move along the cavity in the support section 525, finally move to in the cavity of ground segment 526, because the influence of sand self gravity, sand has certain speed when falling, this makes the sand have certain impact force, when sand contacts support section 525 and ground segment 526 corner position, the impact force of sand can be absorbed by strut assembly 4, in addition the influence of sand self weight, thereby force the strut assembly 4 that is lifted to receive great surpass to the power that deviates from with original direction of motion, make the motion state of the strut assembly 4 lifting that is lifted gradually change the decline motion state towards ground, the strut assembly 4 that is lifted can fall back to ground once more.

At this time, because the lifted connecting seat 121 rotates, when the bracket assemblies 4 fall back to the ground again, an included angle is formed between the two bracket assemblies 4, so that a triangle is formed between the two bracket assemblies 4 and the ground, and the bracket assemblies 4 can more stably support the positioning bracket 11 and the warning board 22. And because sand in the strut assembly 4 towards the wind source side moves downwards into the cavity of the grounding section 526 or the cavity of the support section 525 close to the grounding section 526, the gravity center of the whole device shifts towards the position of the grounding section 526 falling again at this time, but because the two connecting seats 121 are both in an inclined state at this time, the shifting small ball 521 in the connecting seat 121 is positioned on the resetting cambered surface 523 after moving and standing still, namely the gravity center of the resetting small ball is close to the position of the symmetry line in the vertical direction of the two strut assemblies 4 at this time, and the height of the shifting small ball 521 is reduced compared with the height of the initial state, so that the center of the whole device moves downwards more and still can be kept near the vertical symmetry line of the two strut assemblies 4, thereby the gravity center of the whole device is more stable, and the wind resistance of the whole warning device is further enhanced.
