The present invention, for solving the deficiencies in the prior art, provides a kind of wind area that can automatically reduce billboard when blowing hard, and prevents the automatic avoiding mechanism of moment of torsion return wind load that billboard is blown down by blast.
The scheme that solves the technology of the present invention problem is: the automatic avoiding mechanism of moment of torsion return wind load, consists of female column, steel ball, sub-column, panel, steel structure frame, torsion spring, turning axle and step.The panel of three rectangles connects into a triangular prism from beginning to end, and the horizontal projection of described triangular prism is an isosceles triangle.The drift angle of described isosceles triangle is not more than 30 °, and the sub-column vertically arranging is in described triangular prism, and the center of gravity of described isosceles triangle is positioned on the axial line of sub-column.Between the inwall of panel and sub-column, have steel structure frame, steel structure frame is welded as a whole with inwall and the sub-column of panel simultaneously.The lower end of sub-column is the turning axle as a whole with sub-column, and the diameter of turning axle is less than the diameter of sub-column.There is the step of an annular lower surface of turning axle.Lower end and the ground of female column are fixed, on the end face of female column, there is a vertical blind hole, the lower end of described turning axle also becomes with it clearance fit relationship in described blind hole, an annular space of the common formation of sidewall of described step and described blind hole, the identical steel ball of a plurality of diameters is in described annular space, and the diameter of described steel ball is greater than the height of described step.On the turning axle between the edge, blind hole top of the bottom sides edge at sub-column and female column, cover has torsion spring, and the upper end of torsion spring and the bottom sides of sub-column are along being welded as a whole, and the lower end of torsion spring and the blind hole of female column top are along being welded as a whole.
When the wind direction of blast is during over against the long one side of panel, the area that is distributed in the sub-column left and right sides due to this face is also unequal, therefore the wind-force that its left and right sides is subject to is also unequal, under the effect of the wind power difference power of the left and right sides being subject at panel, whole panel rotates around the axial line of sub-column jointly together with steel structure frame and sub-column, when rotation is consistent with wind direction to the drift angle of described isosceles triangle, panel stops the rotation.Because the panel at the place, base of described isosceles triangle has minimum wind area, therefore can be by the abatement of wind being subject to minimum.After blast stops, under the torsional interaction producing at torsion spring, panel rotates again to initial position.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
Because the panel of the present invention's billboard is set to the isosceles triangle that drift angle is not more than 30 °, and can rotate around its center of gravity, therefore can blow while hitting panel in blast, automatically rotate, and by minimum wind surface over against the direction of the wind comes from, the wind-force so just billboard being subject to is reduced to minimum, is not increasing under the prerequisite of rolled steel dosage, has guaranteed the destruction that billboard is not subject to blast.
Due to after the present invention is located at blast and finishes, can automatically make the panel of billboard be returned to original state, save billboard and blown the manual reset after deflection by blast, simplified the maintenance work of billboard.
