Specific embodiment
As shown in Figure 1, this tunnel protection unit, including being placed equidistant with one group or more of the protective device in tunnel two sides,
It contacts with each other between adjacent protective device and is disposed to extend towards length of tunnel direction；
As shown in figure 3, each protective device includes a protective stent 1, the distance of protective stent be must be provided with enough,
Such as 100 meters or 200 meters, it is set as needed, the two sides of the bottom of protective stent 1 rotate to be incorporated on tunnel ground respectively and open up
Rotation slot 4 in, the centre of protective stent 1 has a protection chamber 22, and protecting in chamber 22 to be arranged side by side has one or more to prevent
Guard bar 26, the bottom of fender rod 26 are respectively provided with a sliding shaft sleeve 24, run through one through-hole of setting among sliding shaft sleeve 24, pass through each
The through-hole of sliding shaft sleeve 24 is respectively provided with a shaft 5, and the both ends of shaft 5 are each passed through protective stent 1 and rotate with protective stent 1
The top surface of connection, protection chamber 22 opens up a sliding slot (not shown), and sliding is provided with one or more slide bar 21, slide bar in sliding slot
Insertion is provided with electromagnet assembly 211 inside 21, and the head of each fender rod 26 is respectively provided with an actuation portion 25, actuation portion 25 and cunning
The side face contact of bar 21 is simultaneously attracted by electromagnet assembly 211, and the suction of electromagnet assembly 211 must be enough big, can
At least two tons of weight, the guiding and protection of main face car one kind are carried.
Wherein, it is fixedly welded one group of spring 23 between adjacent slide bar 21, forms one between the end face of adjacent slide bar 21
Buffer distance section, when vehicle because entire protective stent is toppled over when the fender rod among a variety of causes and protective stent contacts, when
After the time relay is started to work, each fender rod 26 is contacted with ground level, is pressed on each fender rod 26 under the tire 51 of vehicle,
The fender rod of each protrusion is laid on ground at this time, as shown in Fig. 2, the downshift lever as one or more uses at this time, reduces vehicle
Speed.
As shown in figure 4, the inside of slide bar 21 offers a closed installation cavity, electromagnet assembly 211 is embedded in and sets
It is placed in installation cavity, one group or more of electromagnet connects and by host control power on/off (not shown), and host passes through spiral shell
Silk fixation is suspended in tunnel wall, and sensing detection component, the signal output end of sensing detection component are provided on fender rod 26
It is transmitted to the signal receiving end of host.
In the present embodiment, as shown in figure 5, sensing detection component is all made of more than one wireless pressure sensor, wirelessly
Pressure sensor insertion is set to inside fender rod 26, and more than one wireless pressure sensor forms a wireless sensor network

The section of rail be in it is T-shaped, the outboard end part of slide bar 21 stretches out in the outside of sliding slot that protection chamber top surface opens up, and passes through T
Character form structure, anti-limited slip block and sliding rail loosen, and sliding rail is opened in sliding slot inner wall two sides.
In the present embodiment, the external extension end of slide bar 21 is respectively formed an actuation plane 213, the actuation on 26 head of fender rod
Portion 25 uses a metal block, and mutually attracted with actuation plane, the two sides of rotation slot 4 open up a shaft hole, protective stent 1
Two sides face shaft hole and be respectively provided with a shaft 8, one group of torque spring is fixedly mounted in shaft 8, shaft 8 passes through torsion bullet
Spring is incorporated in shaft hole and makes under the action of torque spring protective stent perpendicular to pavement of road.
Wherein, rotation slot 4 opens up an inclined contact surface 7 away from the direction of road-center, after fender rod pushes its with incline
Sloped contact surface 7 contact, the tire of vehicle buckle into protect it is intracavitary, advance used for vehicles is limited and is oriented to, and is prevented
Before vehicle continues towards wall and then impinge upon on wall.
Wherein, the one side of rotation slot 4 is bonded with the first rubber block 3, fixes on the inclined contact surface of rotation slot 4 viscous
It is connected to the second rubber block 6, the first rubber block 3 and the second rubber block 6 are used to support protective stent.
The beneficial effects of the present invention are: fender rod of the invention in normal state when all perpendicular to ground, it is perpendicular in this way
The fender rod risen can effectively warn vehicle, and the wall that can be buffered together can be formed after Vehicular impact；And if working as vehicle
Because may make fender rod one end to be detached from when a variety of causes impinges upon fender rod and continues to advance towards wall direction, so that
It is intracavitary that one or two tires of the wherein side of vehicle drop into protection, limits tire and continues to turn to, and makes vehicle
It is moved on along protective stent direction, reaches extraordinary protection and guiding.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
