Referring to fig. 3, 4, 9 and 11, hinges 23 are disposed between the protective covers 7 and the matching plate 6, the protective covers 7 and the matching plate 6 are rotatably connected through the hinges 23, the limiting support seats 22 are fixed at the bottoms of the warning pillars 5, the limiting support seats 22 are connected with the fixing plate 404 through bolts, the limiting support seats 22 support the warning pillars 5 to move in a limiting manner, and the warning pillars 5 can be conveniently detached, maintained and replaced through bolt installation.

Referring to fig. 7, 8 and 12, a plurality of sets of second chains 307 are correspondingly connected between the second driven gears 306 and the third driven gears 406, the servo motor 301 is connected with an external zebra crossing traffic light, the zebra crossing green light is turned on to start the servo motor 301 to rotate, and the red light is turned on to start the servo motor 301 to rotate in the opposite direction.

The working principle of the invention is as follows: when the green light of the crosswalk is on, the servo motor 301 controls the start-up to drive the driving gear 302 to rotate, the first chain 303 engaged with the driving gear 302 drives the two sets of first driven gears 305 to rotate, thereby driving the two sets of rotating shafts 304 and the second driven gears 306 to synchronously rotate, the two sets of second driven gears 306 simultaneously drive the second chains 307 engaged with the two sets of second driven gears to rotate, the second chains 307 drive the multiple sets of third driven gears 406 to rotate, the multiple sets of driving screws 403 gradually and horizontally spirally ascend from the limiting sleeves 402 under the threaded engagement transmission of the inner rings of the third driven gears 406 and the driving screws 403, thereby the fixing plate 404 drives the warning posts 5 on the limiting support seat 22 to horizontally limit and upwards under the action of the bearing 405, when the multiple sets of warning posts 5 ascend to completely extend out of the ground to a certain height, the blocking rods 10 and the buffering rods 8 at two sides and one end of the multiple sets of warning posts 5 are separated from the extrusion, so that the blocking rods 10 and the buffering rods 8 are separated from the extrusion to ensure that the elastic reset characteristics of the second torsion springs 21 and the first torsion springs 13 The barrier rods 10 which are expanded on the two adjacent groups of warning columns 5 are mutually attracted and attached to each other by opposite magnetic poles under the action of the third strong magnet 11, so that each group of barrier rods 10 are mutually connected to form a barrier connecting rod, pedestrians passing through the zebra stripes are effectively protected to prevent the pedestrians from deviating to go out of the zebra stripes, certain traffic accident risks are reduced, the reflective warning strips 14 arranged on the barrier rods 10 and the buffer rods 8 can effectively warn a motor vehicle driver to timely decelerate and stop the motor vehicle, when the motor vehicle driver drives the motor vehicle to decelerate and brake at a slow speed, the motor vehicle can firstly collide with the buffer rods 8, and the motor vehicle can be maximally buffered under the elastic resetting characteristics of the second resetting spring 12 and the first torsion spring 13, the impact force of the motor vehicle is reduced to a certain extent, the damage to the driver caused by impact and the vehicle damage are reduced to a certain extent, after the driver brakes the motor vehicle in time, the motor vehicle can effectively protect the driver, the motor vehicle and pedestrians, when the driver drives the motor vehicle and the speed of the motor vehicle is faster and the brake is not too late or the driver is intentionally collided to the pedestrian, the motor vehicle collides to the buffer rod 8 at a faster speed, the buffer rod 8 is stressed to collide to the direction of the matching groove 15 after being impacted to a certain extent, firstly, the buffer rod 8 and the warning post 5 can reduce a large amount of impact force of the collided motor vehicle and protect the pedestrian to the greatest extent, after the telescopic mechanism 9 on the buffer rod 8 is collided and clamped into the matching groove 15, the telescopic rod 902 in the fixed sleeve 901 can drive the first strong telescopic rod 905 to extend outwards under the action of the first reset spring 904 under the action of the inertia force, and at the moment, under the characteristic that the first strong magnet 905 and the second strong magnet 17 repel at the same level, make visor 7 overturn rapidly and open, after the third reset spring 20 who receives the visor compression relieves the compression, rapid drive flexible post 19 stretches out under the elasticity characteristic that resets, thereby increase warning post 5's overall height, effectively prevented that the motor vehicle from taking place to overturn behind warning post 5 because of the speed is too fast and crossing warning post 5 and hit the occurence of failure that collides with the pedestrian, furthest protects the pedestrian, prevent that the pedestrian from receiving the secondary damage, greatly reduced traffic accident rate, and flexible post 19 stretches out the back and if do not cause the damage can regain repetitious utilization again, and therefore, the production cost is reduced, the practicality of zebra crossing pedestrian automatic protection device is greatly promoted, servo motor 301 reversal can be returned warning post 5 original way and pack up after the red light of zebra crossing lights.
