Example 1:

as shown in fig. 1 to 5, for convenience of description in the present invention, a direction of the guard rail parallel to the road surface is defined as a longitudinal direction, and a direction of the guard rail perpendicular to the road surface is defined as a lateral direction in the following description. The invention provides an automatic alarm type highway guardrail, which comprises a guardrail 1 and a base 2, wherein the base 2 comprises a supporting seat 3, the guardrail 1 comprises a transverse anti-collision damping system 20, and the anti-collision damping system 20 comprises an anti-collision plate 6, a rubber sleeve 8, a telescopic rod 5, a sliding block 4 and a transverse spring 7; the outer side of the guardrail 1 is connected with an outer side anti-collision plate 6 through a sliding block 4 and an expansion rod 5, the anti-collision plate 6 is provided with a vertical fold structure 18, the fold structure 18 can be in various structural forms, and can be a U-shaped fold structure 18 or a V-shaped fold surface or a polygonal fold surface. The outer side of the anti-collision plate 6 is sleeved with a rubber sleeve 8, the rubber sleeve 8 has good elasticity and impact resistance, and the connection mode of the rubber sleeve 8 and the anti-collision plate 6 can be bonding, screw connection and the like. A plurality of transverse springs 7 are arranged on the inner side of the anti-collision plate 6 and between the telescopic rods 5, and at least 2 telescopic rods 5 are arranged; in this embodiment, the number of the telescopic rods 5 is 6, and the telescopic rods 5 comprise telescopic sections 501 and fixed sections 502.

The longitudinal sides of the supporting seat 3 are provided with baffles 15, the transverse sides of the supporting seat 3 are provided with slide rails 11, the sliding block 4 is matched with the slide rails 11 and slides on the slide rails 11, and one longitudinal side of the sliding block 4 is provided with a second longitudinal spring 12 and is connected with the baffles 15; the slide rail 11 is provided with a stopper 110 at a position corresponding to two ends of the slide block 4; the baffle 15, the second longitudinal spring 12, the slide rail 11, the stopper 110 and the slide block 4 form a longitudinal anti-collision damping system 10; the lateral elastic protection mode is triggered when the impact force experienced is small and mainly a lateral impact force 21, or when the vehicle 19 strikes the guard rail 1 in a vertical direction.

Further, the stopper 110 comprises a stopper spring 111 and a stopper 112; the limiting groove 113, the limiting block 112 sets up limiting guide edge 114, and slider guide edge 400 is set up in the slider 4 and the limiting guide edge 114 matching position of limiting block 112. When the longitudinal impact force 22 is received, if the impact force is smaller, the sliding block 4 cannot move longitudinally due to the limiting function of the limiting block 112; when the longitudinal impact force 22 is large, the sliding block 4 will conduct the impact force to the limiting guide edge 114 of the limiting block 112, and the limiting block 112 will compress the limiting spring 111 to move vertically and finally be pressed under the sliding block 4.

Further, in the transverse elastic protection mode, the anti-collision plate 6, the rubber sleeve 8 and the transverse spring 7 are elastically deformed in the transverse direction, and the stopper 110 limits the transverse movement of the sliding block 4 in the sliding rail 11.

Further, a first warning device 17 is mounted at the top end of the sliding block 4, the first warning device 17 is connected with a transverse touch button 14 through a lead 9, and the transverse touch button 14 is arranged at the joint of the transverse spring 7 and the sliding block 4.

Further, first warning device 17 contains bee calling organ, alarm lamp, GPS signal transmitter and solar battery, 4 tops of slider lay solar cell panel and with solar battery electric connection. The transverse touch button 14 is compressed by the transverse spring 7 to trigger the first warning device 17 to give an alarm to warn other vehicles of traffic accidents and to raise the driver's vigilance so as to avoid rear-end collision, and simultaneously, the signal is sent to a road administration control center through a GPS signal transmitter.

It will be appreciated by those skilled in the art that due to the inertia of the vehicle 19 traveling in the longitudinal direction of the roadway, typically, when the vehicle 19 strikes the guardrail 1, the impact force in the transverse direction is small, and the impact force in the longitudinal direction is large, but when the vehicle 19 strikes the guardrail 1 at different angles after a car accident, it may also be the case that the vehicle strikes the guardrail in the approximately vertical direction, and the longitudinal impact force 22 is almost zero, but there is still a certain transverse impact force 21, and then the transverse impact force 21 mainly impacts the guardrail 1.

5-6, in the transverse direction elastic protection mode, the detailed description is subjected to a smaller impact force, when both the longitudinal and transverse impact forces are smaller; or the impact force is mainly a lateral impact force 21, in the extreme case when the vehicle 19 strikes the guardrail 1 vertically, the lateral elastic protection mode will be triggered, which is described by taking the vehicle 19 striking the guardrail 1 vertically as an example. The vehicle 19 contacts with the rubber sleeve 8 on the surface of the anti-collision plate 6 at first, the rubber sleeve 8 is buffered, deformed and compressed, the rubber sleeve 8 absorbs part of the impact force, and transmits part of the impact force to the vertical corrugated structure 18 in a diffusion mode, the anti-collision plate 6 absorbs part of the impact energy through the elastic deformation of the vertical corrugated structure 18, and transmits the rest impact force to the transverse spring 7 on the inner side of the anti-collision plate 6, the transverse spring 7 further absorbs the energy through the elastic deformation, in the process, the telescopic section 501 of the telescopic rod 5 can stretch along with the transverse spring 7, the fixing section 502 of the telescopic rod 5 can play a role of guiding and limiting, so that the transverse springs 7 deform uniformly and absorb the impact force, at the moment, because the transverse impact force 21 is mainly transverse, the impact force in a longitudinal mode can be almost ignored, and under the limiting effect of the limiter 110 on the slide rail 11, the guard rail 1 does not move in the longitudinal direction. After the vehicle has been put aside, guardrail 1's horizontal spring 7, anticollision board 6, telescopic link 5 and rubber sleeve 8 automatic recovery original state, consequently, horizontal spring 7, anticollision board 6, telescopic link 5 and rubber sleeve 8 form horizontal crashproof shock mitigation system 20 that slows down the impact force at many levels together, and personnel in the protection vehicle avoid appearing reverse impact force, cause the injured phenomenon to appear, guarantee people's life safety, also protected the guardrail simultaneously, avoid carrying out repair work. In this process, since the vehicle 19 strikes the guard rail 1 in the vertical direction, as shown in fig. 5, the elastically deformed guard rail 1 can be automatically restored from the compressed state to the original state (shown in fig. 2), defining this process as a lateral elastic protection mode.

As shown in fig. 6, assuming that the impact force at the time of the collision of the vehicle 19 is small, both the longitudinal impact force 22 and the lateral impact force 21 are small, the impact process of the lateral impact force 21 is similar to that described above when the guardrail 1 is hit in the approximately vertical direction; in the longitudinal direction, because of the existence of the smaller longitudinal impact force 22, the longitudinal impact force 22 is transmitted to the slide rail 11 through the slider 4, but the longitudinal impact force 22 is absorbed by the stopper 110 under the limiting action of the stopper 112 of the stopper 110 on the slide rail 11.

In the transverse elastic protection mode, when the transverse spring 7 is compressed in the collision process, the transverse spring 7 presses the transverse touch button 14, and the first warning device 17 gives an alarm. When the crash panel 6 automatically returns to the original state after the vehicle 19 is removed, the transverse spring 7 also returns to the original state, the transverse spring 7 leaves the transverse touch button 14, and the warning device 16 stops giving the alarm. The alarm information sent by the first warning device 17 can remind other vehicles of traffic accidents and the driver of improving the vigilance so as to avoid rear-end collision. Meanwhile, the first warning device 17 sends out warning information through wireless signals, the GPS signal transmitter sends out GPS signals, and the road administration center can judge the position of a traffic accident in the first time by identifying the information sent by the first alarm 17, can pre-judge the damage condition of the guardrail and the occurrence of a lighter traffic accident and carry out corresponding emergency treatment.

The outer side of the anti-collision plate 6 is sleeved with a rubber sleeve 8, the rubber sleeve 8 has good elasticity and impact resistance, and the connection mode of the rubber sleeve 8 and the anti-collision plate 6 can be bonding, screw connection and the like. A plurality of transverse springs 7 are arranged on the inner side of the anti-collision plate 6 and between the telescopic rods 5, and at least 4 telescopic rods 5 are arranged; the telescopic rod 5 comprises a telescopic section 501 and a fixed section 502.

Further, in the bidirectional protection mode, the anti-collision plate 6, the rubber sleeve 8 and the transverse spring 7 are firstly elastically deformed in the transverse direction, and then the slider 4 compresses the stopper 110 and compresses the second longitudinal spring 12 to be deformed so as to drive the guardrail 1 to longitudinally displace. Specifically, the stopper 110 includes a stopper spring 111 and a stopper 112; the limiting groove 113, the limiting block 112 sets up limiting guide edge 114, and slider guide edge 400 is set up in the slider 4 and the limiting guide edge 114 matching position of limiting block 112. When the longitudinal impact force 22 is large, the sliding block 4 will conduct the impact force to the limiting guide edge 114 of the limiting block 112, and the limiting block 112 will compress the limiting spring 111 to move vertically and finally be pressed under the sliding block 4.

Further, a second longitudinal spring 13 is arranged on the other longitudinal side of the sliding block 4 and is connected with a baffle 15, so that the impact resistance in the longitudinal direction can be enhanced.

When the impact force is large when the vehicle 19 impacts the guardrail, the bidirectional protection mode is triggered, and in particular, generally speaking, because the impact force of the vehicle 19 is large and the vehicle collides with the guardrail 1 at a certain angle, the impact force can be decomposed into a transverse impact force 21 and a longitudinal impact force 22, and as shown in fig. 7, the first stage is the buffering process of the transverse impact force 21: the vehicle 19 firstly contacts with the rubber sleeve 8 on the surface of the anti-collision plate 6, the rubber sleeve 8 is buffered, deformed and compressed, the rubber sleeve 8 absorbs part of impact force, and simultaneously transmits part of the impact force to the vertical corrugated structure 18 in a diffusion mode, the anti-collision plate 6 absorbs part of impact energy through the elastic deformation of the vertical corrugated structure 18, and simultaneously transmits the rest impact force to the transverse spring 7 on the inner side of the anti-collision plate 6, the transverse spring 7 further absorbs energy through elastic deformation, in the process, the telescopic section 501 of the telescopic rod 5 can stretch along with the transverse spring 7, the fixing section 502 of the telescopic rod 5 can play a role in guiding and limiting, so that the transverse springs 7 deform in a balanced mode and absorb the impact force, at the moment, the transverse impact force 21 is absorbed, the transverse impact force 21 is prevented from rebounding back to the vehicle, and the vehicle safety of personnel is protected.

The second stage is a buffering process of longitudinal impact force 21, the vehicle 19 transmits the longitudinal impact force 22 to the sliding block 4, the sliding block 4 transmits the impact force to a limiting guide edge 114 of a limiting block 112, the limiting block 112 compresses a limiting spring 111 to move in the vertical direction and is finally pressed below the sliding block 4, and meanwhile, the second longitudinal spring 12 connected with the sliding block 4 and the baffle 15 is stretched and deformed in the process; and the other side of the slider 4 in the longitudinal direction is also provided with a second longitudinal spring 13 and is connected with a baffle 15, and the second longitudinal spring 13 is compressed and deformed. The guardrail 1 is driven to longitudinally displace through the tensile deformation of the second longitudinal spring 12 and the compression deformation of the second longitudinal spring 13, and longitudinal impact force 22 is absorbed, so that transverse impact force 21 is prevented from rebounding to a vehicle, the vehicle safety of a worker is protected, meanwhile, the guardrail is also protected, and the repair work is avoided.

In the process, as the vehicle 19 impacts the guardrail 1, as shown in fig. 7, the guardrail 1 is elastically deformed transversely and displaced longitudinally, and when the vehicle 19 moves away, the guardrail 1 can automatically restore the original state (shown in fig. 2), thereby defining the process as a bidirectional protection mode.

Therefore, in the bidirectional protection mode, the transverse spring 7, the crash panel 6 and the rubber sleeve 8 form a multi-level transverse crash cushion system 20 together.

In the process of collision of the longitudinal impact force 22, when the second longitudinal spring 12 is compressed, the second longitudinal spring 12 presses the longitudinal touch button 16, the second warning device 171 gives an alarm, and the first warning device 17 and the second warning device 171 give an alarm, so that other vehicles can be reminded of a traffic accident, and a driver needs to be alerted to avoid rear-end collision. Meanwhile, the first warning device 17 and the second warning device 171 send out GPS signals to the road administration center through wireless signals, the road administration center can judge the position of a traffic accident in the first time by identifying the information sent by the first warning device 17 and the second warning device 171, and can pre-judge the damage condition of the guardrail and the serious traffic accident and carry out corresponding emergency treatment.
