As shown in fig. 1-4, when the device of the present invention is in the initial state, the swash spring 58 is in the relaxed state, the warning light 61 is in the off state, the electromagnet shaft holders 36 and 23 are not started, the moving gear 22 and the long gear 27 are in the non-engaged state, the clutch spur gear 38 and the driving spur gear 15 are in the non-engaged state, the internal electromagnet 35 is in the compressed state, the thrower spring 51 is in the relaxed state, the contact spring 42 is in the relaxed state, and the latch 55 and the contact block 43 are in the abutting state;
sequence of mechanical actions of the whole device:
when the automobile starts to work, when the automobile tends to press lines in the process of running in a tunnel, the tire of the automobile presses down the sliding inclined block 59, the sliding inclined block 59 overcomes the elastic force of the inclined block spring 58 to move downwards to abut against the motor button 56, at the moment, the motor 14 starts to start, and meanwhile, the moving gear 22 drives the sliding shaft 16, the moving gear 22 and the intermediate belt wheel 17 to move rightwards under the thrust action of the inclined block pull rope 57 until the moving gear 22 is meshed with the long gear 27;
the motor 14 rotates to drive the motor shaft 40 to start rotating, the motor shaft 40 rotates to drive the driving spur gear 15 and the right belt pulley 33 to start rotating, the right belt pulley 33 rotates to drive the left belt pulley 19 and the middle belt pulley 17 to start rotating through the conveyor belt 21, the left belt pulley 19 rotates to drive the left belt pulley shaft 20 to start rotating, the middle belt pulley 17 rotates to drive the sliding shaft 16 to start rotating, the sliding shaft 16 rotates to drive the moving gear 22 to start rotating, the moving gear 22 rotates to drive the long gear 27 to start rotating, the long gear torsion spring 26 starts accumulating force to drive the hollow connecting rod 12 to start rapidly moving downwards through the rack 32, the clutch spur gear shaft 34 slides in the sliding cavity 11, when the hollow connecting rod 12 descends until the clutch spur gear shaft 34 contacts with the arc-shaped threaded part 13, the clutch shaft 23 and the shaft seat electromagnet 36 start, and the electromagnet shaft seat 36 moves forwards under the repulsive force of the, thereby driving the electromagnet shaft seat 36 and the clutch spur gear 38 to move forwards until the clutch spur gear 38 is meshed with the driving spur gear 15, the driving spur gear 15 rotates to drive the clutch spur gear 38 to start rotating, the clutch spur gear 38 rotates to drive the clutch spur gear shaft 34 to rotate, at the moment, the reset torsion spring 30 starts to accumulate force, and simultaneously, the arc-shaped threaded part 13 drives the hollow connecting rod 12 to move forwards, so that the hollow connecting rod 12 can move forwards for a distance along with the automobile, and the automobile can not finish the action of line pressing and overtaking;
if the hollow connecting rod 12 descends, the contact block 43 contacts the vehicle body, the contact block 43 overcomes the elastic force of the contact block spring 42 and moves upwards to the position where the clamping block 55 is clamped in the clamping block 66, meanwhile, the movable rotating block 25 moves leftwards under the action of the pulling force of the moving gear pulling rope 24 and drives the moving gear 22, the sliding shaft 16 and the intermediate belt pulley 17 to move leftwards, so that the moving gear 22 is disengaged from the long gear 27, the long gear 27 starts to rotate reversely under the action of the accumulated force of the long gear torsion spring 26, and therefore the hollow connecting rod 12 is driven to be retracted into the moving cavity 31 through the rack 32, and the clutch straight gear shaft 34 starts to rotate reversely under the action of the accumulated force of the reset torsion spring 30, and therefore the hollow connecting rod 12 is;
when hollow connecting rod 12 descends to a certain position, the vehicle that two lanes travel can drive blade 46 and begin to rotate, thereby drive pivot 41 and trigger button 47 and begin to rotate, can drive blade 46 fast rotation if the speed of a motor vehicle is too fast this moment, thereby it gets rid of piece 50 to drive centrifugal wheel and overcome the elasticity of getting rid of piece spring 51 and move to butt trigger button 47 to the direction of keeping away from pivot 41 under the effect of centrifugal force, trigger button 47 presses and drives warning light 61 and begin to light, remind the preceding vehicle speed of a motor vehicle in rear too high, it is prudent to walk slowly, keep the vehicle distance, prevent the occurence of failure.
The invention has the beneficial effects that: whether the vehicle has the trend of line ball or the line ball action is judged, reminds the vehicle through the tracking to the vehicle of traveling when having this kind of condition, makes the vehicle rule travel in the same lane in the tunnel, and the light in the tunnel is not as external simultaneously, and when the vehicle in the tunnel traveled too fast, reminds rear vehicle to keep certain vehicle distance with the vehicle that the place ahead hypervelocity was gone in the tunnel through the mode of bright light, reduces the emergence of traffic accident in the tunnel.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
