The working process of the invention is as follows: end unlocking, driving rotation and end locking;
specifically, the method comprises the following steps:
unlocking the end part: inserting a movable section guardrail 1 on a middle guardrail of a low-lying road section, under normal conditions, filling sand grains 8 in a cavity 5 at the lower end of a pin shaft 6, supporting the pin shaft 6 at the highest position by the sand grains 8, extending the upper end of the pin shaft 6 out of the cavity 5 and inserting the pin lug 7, locking two ends of the movable section guardrail 1, and placing the movable section guardrail in the middle of a road in parallel with the road to be used as a common guardrail; when the water passing holes 9 of the upper cavity 5 are submerged by accumulated water on the road surface in extreme weather, water flow can flow into the cavity 5 from the water passing holes 9 on one side and flow out of the cavity 5 from the water passing holes 9 on the other side, sand particles 8 in the cavity 5 quickly run off along with the water flow under the erosion action of the water flow, the pin shaft 6 can gradually descend, the upper end of the pin shaft 6 is pulled out of the pin lug 7, and the two ends of the guardrail 1 at the movable section are unlocked;
driving to rotate: after the two ends of the movable section guardrail 1 are unlocked, the two unidirectional impellers 10 rotate and retract under the impact of water flow, the blade plate 15 on one side rotates and retracts, the blade plate 15 on the other side is blocked by the stop block 16 and cannot retract, the unidirectional impellers 10 rotate under the action of the force difference of the blade plates 15 on the two sides, the rotation directions of the two unidirectional impellers 10 are the same, the two unidirectional impellers 10 drive the two small gears 11 to rotate, and the two small gears 11 revolve around the large gear 12 while rotating, so that the movable section guardrail 1 is driven to rotate around the mandrel 2;
end locking: when the movable section guardrail 1 rotates to the position of the cross bar, the movable section guardrail 1 is blocked by the fixing piles 13 and cannot rotate continuously, meanwhile, the guardrail at the top of the guardrail passes through the two one-way rods 18 and enters between the two cross rods 17, and the guardrail cannot exit from the cross rods 17 due to the action of the one-way rods 18, so that the movable section guardrail 1 is locked at the position of the cross bar.
If people fall into the flood, the people can be blocked by the movable section guardrail 1, and the people are prevented from being washed away and lost or being in distress.
According to the invention, the movable section guardrail 1 is inserted into the guardrail of the easily-damaged section, two ends of the movable section guardrail 1 are unlocked when water is accumulated on the road surface, and then the movable section guardrail 1 is driven by water flow through the impeller to rotate to be transversely blocked on the road, so that people falling in the flood can be intercepted, the people can be self-rescued by holding the guardrail or wait for rescue at the guardrail, the people are prevented from being washed away and being in distress, and the casualties in flood disasters are reduced.
