Of course, other telescopic structures can be adopted for the transverse telescopic mechanism and the longitudinal telescopic mechanism, so long as the movable top plate 3-3 and the blocking body 4-2 can move, such as a hydraulic telescopic structure.
In this embodiment, there are a plurality of warning isolation balls 2-5, and each warning isolation ball 2-5 corresponds to one protection slot 3-2, and each protection slot 30-2 corresponds to one blocking body 4-2.
The slow running vehicle is driven into a non-motor vehicle lane. The warning isolation ball 2-5 on the non-motor vehicle lane edge line 1 (the edge of the slow-moving traffic road) is compressed (see the warning isolation ball 2-1 after rolling of the slow-moving vehicle in fig. 3), the corresponding protection groove is opened (see the protection groove 3-1 after opening of the movable top plate in fig. 3), a semicircular concave protection groove is formed, and the third group of protection mechanisms 4 (arc blocking devices) are not started.
As shown in fig. 4, after a slow-driving vehicle enters a non-motor vehicle lane (slow-driving traffic road), an alarming isolation ball 2-5 is rolled, the height of the alarming isolation ball 2-5 becomes low, at this time, the extruded non-newton fluid 2-2 pushes a piston rod 2-4 through a communicating pipe 2-3 and drives a vertical rod 3-5 to enable a movable top plate 3-3 to move into a movable top plate groove 3-4, at this time, a semicircular concave protection groove is formed, and after the driving motor vehicle falls into the protection groove, the driving motor vehicle stops moving.
When a fast-driving vehicle drives into a non-motor vehicle lane (a slow-driving traffic road), and rolls on the warning isolation balls 2-5 on the edge line 1 (the edge of the slow-driving traffic road), the height of the warning isolation balls 2-5 is unchanged, the material is hard, and the fast-driving vehicle is decelerated; at this time, the corresponding protective slot is opened (see the protective slot 3-1 after the movable top plate is opened in fig. 5), so as to form a semicircular concave protective slot; the third group of protection mechanisms 4 (arc stopping devices) are started, and 1/4 arc-shaped stopping bodies are lifted to the road surface (see the lifting stopping bodies 4-1 in fig. 6).
