The following describes in detail the use steps of a smart partition fence that can automatically prevent pedestrians from overturning in conjunction with
At the beginning, the slider 20 is in the upper limit position, and the first spring 23 is always in a compressed state. The electric wire 24 is in an interrupted state, and the pushing block 30 and the fixing plate 31 are in an upper limit position.
When someone tries to climb over the guardrail, if they rest on the fixed plate 31 with their hands or feet, the fixed plate 31 and the push block 30 are pushed down, and then the pressure sensor 32 is pressed down by the second spring 33, and the pressure sensor feels the pressure change. 32 Start the first motor 37 on the same side, and then the first motor 37 inflates the elastic airbag 28 on the same side, so that the elastic airbag 28 is inflated to a semi-saturated state. The end of the elastic airbag 28 that is far from the center of symmetry protrudes to the outside to try to overturn The person cannot continue to be close to the guardrail, but when the person steps on the borrowing force, because the elastic airbag 28 is in a semi-saturated inflation state, the elastic airbag 28 will sag so that the pedestrian cannot be surpassed by the force. When the fixed plate 31 is no longer under pressure, the pressure sensor 32 The first motor 37 on the same side is started to reverse, and the air in the elastic bladder 28 is drawn back into the gas storage cavity 34. The elastic bladder 28 is stored in the storage cavity 27 under the elasticity of its own material.
If you grasp the rocker 13 or the fixed block 16 and continue to try to climb over the guardrail, when the rocker 13 and the fixed block 16 are stressed, due to the action of the connecting rod 18 and the limit rod 15, the rocker 13 and the fixed block 16 shake and slide down and pass The turntable 22 drives the slider 20 to slide down. When the slider 20 slides to the lower limit position, the conductive block 26 is inserted into the slot 25 and the electric wire 24 is connected, and the second motor 43 is started. At this time, the first gear 40 follows the slider. 20 slides to the lower limit position and meshes with the second gear 47, the second motor 43 starts to drive the first helical gear 44 to rotate, and then the gear shaft 45 is rotated through the gear meshing, and then the gear shaft 45 drives the second gear 47 to rotate, the second The gear 47 rotates the rotating shaft 21 through the gear meshing, and then the turntable 22 rotates and drives the connecting rod 18 to rotate. The connecting rod 18 drives the lower end of the rocker 13 to flip, so that the upper ends of the rocker 13 and the fixing block 16 are constantly shaken and cannot be overturned by force. To prevent pedestrians from jumping over, when there is no pressure interference between the rocker 13 and the fixed block 16, the slider 20 slides up under the action of the first spring 23, the conductive block 26 leaves the slot 25, and then the electric wire 24 is disconnected, and then The second motor 43 stops operating Return to the initial state.
The beneficial effect of the present invention is that the present invention can effectively separate the flow of people or traffic, and automatically start when a pedestrian tries to climb over the guardrail, so that the pedestrian can't climb the borrowing force in a gentle operation manner, thereby preventing Pedestrians crossing fences cause traffic jams or even traffic safety accidents, improving the safety of traffic roads, and automatically stopping when no one is crossing, saving environmental protection.
