[0031] The following describes the steps of using a landslide protection device in detail in conjunction with FIGS. 1 to 10:

[0032] In the initial state, the baffle plate 14 is at the lower limit position, the toothed slider 27 is at the right limit position, and the push plates 21 are at a distance from each other at this time.

[0033] When no landslide occurs, the small rolling stones that roll down on the mountain 11 can enter the cavity 13 through the through grooves 56 to prevent the small rolling stones from accumulating on the left side of the roadbed 12.

[0034] When a landslide occurs, the motor 49 is started to drive the driving sprocket 31 through the motor shaft 30, and the right sprocket 38 is driven to rotate through the chain 28, and the driving gear 59 is driven to rotate through the short shaft 37, which in turn drives the driven gear 60 Rotate, then drive the pinion 45 through the vertical shaft 39, and then drive the transmission gear 46, and then drive the large gear 41, and then rotate the cleaning plate 44 through the slow shaft 43. As the pinion 45, the transmission gear 46, and the large Gear 41 is a reduction transmission. At this time, the cleaning plate 44 blocks the vehicle on the roadbed 12 to prevent the vehicle from being hit by rolling stones. When the active sprocket 31 rotates, the left sprocket 48 is driven by the chain 28 to rotate, and then through the connecting shaft 16 The connecting gear 15 is driven to rotate, which in turn drives the rack 36 and the baffle 14 to rise, further drives the link 20 to swing through the left hinge shaft 17, and further drives the toothed slider 27 to slide through the right hinge shaft 23. It will be in contact with the support plate 22. The rotation of the motor shaft 30 can simultaneously drive the driving pulley 50 to rotate, and then the driven pulley 53 is driven to rotate by the transmission belt 51, and the pusher is driven by the screw 54. 21 is close to each other, so that the toothed slider 27 is always engaged with the push plate 21, and the support plate 22 is always blocked on the upper side of the toothed slider 27 to prevent the rolling stone from falling and smashing the toothed slider 27. When the baffle 14 rises When the upper limit position is reached, the cleaning plate 44 just rotates to ninety degrees, and the motor 49 is stopped at this time. At this time, the toothed slider 27 cannot slide to the right, and then the baffle 14 is supported by the link 20, and the rolling stone can roll into the cavity. Inside 13, under the elastic force of the torsion spring 57, the rolling stones can be cushioned by the buffer plate 33, and the baffle plate 14 can prevent a large number of rolling stones from falling on the roadbed 12, and at the same time can prevent the roadbed 12 from being damaged by the rolling stones.

[0035] When the landslide is over, the motor 49 is reversed to drive the device back to its original state. When the cleaning plate 44 is reversed, the rolling stones on the subgrade 12 can be pushed to both sides to concentrate, and a road can be quickly cleared out. Convenient for rescue vehicles.

[0036] The beneficial effect of the present invention is that the present invention is arranged in the roadbed in a region where the frequency of landslides is high. After the landslide occurs, the rolling stones can be dredged and guided, and it can also avoid the traffic congestion caused by the rolling stones and the like falling directly on the road. Slope. The speed of the rolling stones is relatively fast. When the rolling stones are dredged, the rolling speed is slowed down. After the landslide ends, the device is restored to the initial state and the rolling stones falling on the road surface can be automatically cleaned.

[0037] In the above manner, those skilled in the art can make various changes according to the working mode within the scope of the present invention.
