[0042] The specific implementation is that: the reinforcing mechanism 6 is arranged, the connecting plate 65 is blocked by the stop blocks 63, and the connecting plate 65 pulls the guardrail plate 2 through the steel cable 61, at this time, the anti-collision effect of the guardrail plate 2 is further improved, when the guardrail plate 2 is subjected to a strong impact, the impact force may affect the children, the stop blocks 63 made of plastic material are also broken, the connecting plate 65 moves upwards and extrudes the sensor 62, the sensor 62 is contacted by the connecting plate 65 to send a signal and control the protection mechanism 4 to work.

[0043] Working principle: the fixed shell 1 is buried in the ground, and the top of the guardrail plate 2 is exposed to the ground. If the child passage is protected, the motor 73 is controlled to work to drive the threaded column 75 to rotate, and the two threaded columns 75 can rotate simultaneously under the action of the second rotating shaft 74. At this time, the two threaded nuts can approach each other, the threaded nut drives one end of the connecting rod 72 to move, the other end of the connecting rod 72 can push the lifting plate 71 to move up, the lifting plate 71 can push the guardrail plate 2 to move up and away from the fixed shell 1. The device is provided with two, the guardrail plates 2 in the two devices move up at the same time and block on the road. When the board moves up, the pull rope 318 can be pulled and the rotating wheel 320 can be rotated, the rotating wheel 320 can drive the gear 319 to rotate, and the gear 319 can drive the top plate 31 and the vertical plate 314 to move up under the action of the teeth 317. After the top plate 31 moves up and leaves the air slot, the top plate 31 can rotate and overlap on the guardrail plate 2 under the action of the hinge. At this time, the top plate 31 is in a horizontal state, and after the two devices are started at the same time, the two top plates 31 contact each other, which can effectively prevent rain and sun, and make the children safer when passing through the road. The safety protection effect of children is better. If there is water on the road when it rains, the knob is pulled to move through the push plate 33 to drive the clamping rod 36 to move. The clamping rod 36 moves randomly in the sleeve, and when the clamping rod 36 is no longer clamped in the clamping groove, the rotating shaft 39 is no longer fixed. At this time, the supporting plate 312 is no longer fixed, and at the same time, the lifting rope 311 is released and can control the supporting plate 312 to move down. The supporting plate 312 no longer fits with the top plate 31, and the supporting plate 312 can move to a position away from the ground by a certain height. At this time, the child can step on the supporting plate 312 to pass through the road, and effectively avoid the child's shoes from being wetted by the accumulated water. When the lifting plate 71 moves up and pushes the guardrail plate 2 to extend out of the ground, the lifting plate 71 can push the extrusion plate 54 to move up, the extrusion plate 54 can extrude the air cylinder 53 to make it compressed, so that the air in the air cylinder 53 can be extruded and delivered to the air cushion 51 through the air pipe 55. At this time, the air cushion 51 expands and covers the guardrail plate 2, improving the anti-collision ability of the guardrail plate 2. When the vehicle mistakenly hits the guardrail plate 2, the air cushion 51 can have a good blocking and buffering effect. The connecting plate 65 is blocked by the block 63, and at the same time, the connecting plate 65 pulls the guardrail plate 2 through the steel cable 61. At this time, the anti-collision effect of the guardrail plate 2 is further improved. When the guardrail plate 2 is hit hard, the impact force may affect the child, and the block 63 made of plastic material will also break, and the connecting plate 65 moves up and extrudes the sensor 62. The sensor 62 is contacted by the connecting plate 65 to send a signal and control the electronic valve to work to no longer block the connecting pipe 45. At this time, the high-pressure air in the high-pressure tank 44 is instantly discharged into the air chamber plate 42, and then the air in the air chamber plate 42 enters the multiple air bags 43, so that the air bags 43 can expand and extend out of the hole, and cooperate with the silica gel pad 41 to achieve good protection effect for children, avoid children from falling and hitting the protection plate to be hurt.

Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, and the modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
