Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment: as shown in Figure 1, anti-high wind billboard is made of billboard board face 1, gear train 2, speed reduction unit 3, motor 4 and positive and reverse rotation control circuit thereof, anemometer; It is characterized in that: billboard board face is venetian blind type and is provided with blade electromagnetic locking device 5 that the rotation axis 7 of each blade 6 of venetian blind type billboard board face is assemblied on the gear train 2; Motor is by speed reduction unit and gear train assembling; Anemometer has wind sheltering relay and reset relay, and two relays are connected with the motor positive and reverse rotation control circuit respectively, and the wind sheltering relay also is connected with blade electromagnetic locking device; Put in place limit switch and be rotated in place limit switch of normal position is set respectively on the gear train.
Venetian blind type billboard board face is that whole advertising sign face is divided into several blades, each blade is arranged in parallel, horizontal stroke (indulging) at each blade is equipped with rotation axis on the axis, rotary shaft end is equipped with bearing 8, the outer ring of bearing is installed on the support that supports billboard, each blade can rotate around it nearly angle of 90 ° of (support) rotary oscillation on relative its base frame at least, base frame and billboard shape such as window shutter (size dimension of blade and vertically and horizontally arranged division are according to the actual size and the operating position adjustment of whole billboard).Be equipped with in an end of the rotation axis of each blade and can accept the sprocket wheel that the motor motion is transmitted.
Motor, (worm and gear) speed reduction unit, sprocket wheel chain are formed power drive system.The power that driven vane is rotated is from motor.The high-speed rotation of motor becomes slow rotation through the speed reduction unit of big reduction of speed ratios such as worm and gear, through the sprocket wheel chain motion is passed to the rotation axis of each blade again.
Automatic control system is by anemometer, relay, motor forward and backward driving circuit, billboard electric locking device, blade normal position limit switch and be rotated in place limit switch etc. and form.Wherein comprise air velocity transducer, wind speed measuring circuit, wind speed display circuit, early warning wind speed setting button and comparator circuit etc. in the anemometer.The motor positive and negative rotation circuit is to utilize general universal circuit, and relay is switched on or switched off rated voltage and electric current as auxiliary reclay driving motor conversing contactor, realizes the start and stop and the rotating of motor; Blade electromagnetic locking device blade begin to rotate windproof before and set back after blade and its base frame are locked, prevent that blade from rocked by the influence generation of little wind at ordinary times, influencing advertising results.When blade need rotate, blade electromagnetic locking device was in releasing orientation; Blade normal position limit switch and be rotated in place the rotational angle that limit switch limits blade provides to control system to rotate in place signal and to stop the rotation of motor.Control procedure as shown in Figure 2.
Wind detection sensor is installed in maybe can measure near the place of wind speed in real time of billboard on the billboard.The electric signal of sensor output reflection wind speed size is sent into anemometer, and the metering circuit in the anemometer is converted into air speed value to signal, and one side is sent into display and demonstrated the wind speed size, and one side is sent into an input end of wind speed comparator circuit; The early warning wind speed and the wind speed that resets are set button can set billboard the design strength maximum wind velocity that can resist and the survival wind speed that can make billboard work, setting value is converted to electric signal be input to the wind speed comparator circuit.When real-time wind speed during less than the early warning wind speed, comparator circuit no-output, blade is locked on its base frame by blade electromagnetic locking device open and flatly, normally brings into play advertising effects; When real-time wind speed met or exceeded the early warning wind speed, comparator circuit sent closure signal to the wind sheltering relay, and this signal at first makes blade electromagnetic locking device loosen, and connects the motor prograde circuit then.Motor begin just to change and by speed reduction unit speed is reduced to suitable rotating speed after pass to sprocket wheel, sprocket wheel passes to the sprocket wheel that is installed on the blade rotation axle to motion by chain, thereby drives blade rotation.
Wind detection sensor and anemometer are measured the ambient wind velocity of billboard at any time, when ambient wind velocity is lower than the startup wind speed of setting, the power that wind acts on the billboard is lower than the Line Segment Bill Board Design intensity level, billboard is safe, automatic control system is failure to actuate, locking device locking billboard stably maintains the original state it, normally brings into play the effect of its advertising; When ambient wind velocity surpasses the wind speed setting value, illustrating has danger above its design strength to the acting force of billboard by wind (wind direction does not have some difference simultaneously, wind speed when getting positive effect value for referencial use), the comparator circuit of surveying in the wind setting device sends signal to output relay, circuit start motor.Motor drives the rotation of venetian blind type billboard board face blade by speed reduction unit deceleration, sprocket wheel chain gearing, reduces the billboard front face area.Rotate to billboard pressing limit switch behind the specified angle, motor stops operating.Because adopt the speed reduction unit of turbine and worm or other big speed ratio, so can keep self-locking state after the motor stall, the uneven wind-force that acts on the billboard can not make the billboard blade swing back and forth; When ambient wind velocity eases down to the lower limit of specifying wind speed, comparator circuit sends motor counter-rotating instruction by another output relay, the motor counter-rotating, the drive billboard resets, limit switch sends signal when finishing resetting, and stops the rotation of motor and start locking device movable billboard is locked on its framework.
The course of work of the anti-high wind billboard of present embodiment, the complete the inventive method that realized.
