Summary of the invention

The present invention seeks to resist defective and technical matterss such as the wind loading rating of the inadequate natural endowment of high wind and some existing wind resistance billboards is limited in order to solve existing billboard, a kind of roller shutter type wind resistance billboard is provided.

The present invention is achieved in that a kind of roller shutter type wind resistance billboard, comprises board face, track, wind pressure sensor, external frame, column type rotating shaft, drive motor, support, programmable controller, positive contactor, counter-rotating contactor, positive turn-off pass, reversal switch and shutdown switch.The board face is to shrink folding form around column type rotating shaft roller shutter type, inside, external frame right side is provided with column type rotating shaft and drive motor, the column type rotating shaft is fixedlyed connected with board face right-hand member, the track of use when external frame all is equipped with in the both sides up and down and moves for the board face, the inboard of track has support respectively, at the billboard top wind pressure sensor is installed, to the pre-set parameter measurement blast of wind pressure sensor; Wind pressure sensor is connected with programmable controller, and programmable controller is connected with shutdown switch with positive contactor, counter-rotating contactor, positive turn-off pass, reversal switch respectively.

To measure blast very big and when continuing for some time when wind pressure sensor, the positive turn-off that triggers positive contactor by programmable controller closes, drive motor is just changeing startup, roller shutter type shrinks in the external frame of column type rotating shaft but trump card is equipped with towards a side, this moment, the board face was packed up gradually, and after the board face was all packed up, the board face touched the motor shutdown switch simultaneously, supporting structure all exposes, and wind passes through support; When wind pressure sensor measures blast normally and continues for some time, trigger the reversal switch of counter-rotating contactor by programmable controller, the drive motor counter-rotating starts, launch shrinking the board face roller shutter type of rolling originally, the board face touched the shutdown switch of drive motor when expansion was finished, and this moment, the board face launched to recover former state.

Beneficial effect of the present invention: because the size of blast is variable, the size that acts on each position on the roller shutter type wind resistance billboard also is not quite similar, and blast has significantly destructive to blast at the roller shutter type billboard in the size of the direct acting surface of billboard board face, the present invention all packs up roller shutter type wind resistance billboard board face, only the support of remaining billboard exposes, reduced the effect of blast to billboard greatly, thereby roller shutter type wind resistance billboard is not destroyed when strong wind, effectively reduce the maintenance cost, reached few input and long-lived economic benefit.
