[0035] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0036] A road isolation guardrail includes a supporting body 1, a load-bearing seat 12 is arranged on one side of the supporting body 1, a limit baffle 22 is slidably installed on the load-bearing seat 12 through an adjustment mechanism 3, a supporting base 11 is fixedly arranged in front of the load-bearing seat 12, the supporting base 11 and the load-bearing seat 12 are rectangular seats, which can be made of PVC material, wherein the supporting body 1 composed of the load-bearing seat 12 and the support base 11 is fixed on the ground.

[0037] An anti-collision guardrail frame 2 is arranged on the supporting base 11. The anti-collision guardrail frame 2 is a rectangular frame, and the anti-collision guardrail frame 2 is made of flexible PVC material, which avoids the anti-collision guardrail frame 2 from directly breaking after being hit. At the same time, it can also provide vibration reduction protection for vehicles and pedestrians that collide, thereby avoiding damage to vehicles and injuries to pedestrians.

[0038] A light panel 212 is installed in front of the anti-collision guardrail frame 2, an anti-collision frame 21 is fixedly arranged inside the anti-collision guardrail frame 2, a buffer assembly 4 is installed between the limit baffle 22 and the anti-collision frame 21, a monitoring slot 215 is provided in the anti-collision frame 21, a smoke alarm 216 is arranged in the monitoring slot 215, and the smoke alarm 216 in the prior art is adopted. A battery is arranged inside the smoke alarm 216 and does not need to be powered by electric wires. When the combustion particles of the smoke alarm 216 are detected by the smoke alarm 216 after a vehicle collides and burns, the smoke alarm 216 will emit a crisp and loud pulsating alarm sound.

[0039] A reinforcing rod 214 is installed in front of the monitoring slot 215 . The reinforcing rod 214 is fixedly connected to the anti-collision frame 21 through fastening bolts. The reinforcing rod 214 can protect the anti-collision frame 21 and prevent the anti-collision frame 21 from falling off or breaking.

[0040] The adjusting mechanism 3 comprises an adjusting cylinder 33 fixed on the load-bearing seat 12 , an adjusting threaded rod 32 is installed in the adjusting cylinder 33 , and an adjusting disk 31 is fixedly installed at one end of the adjusting threaded rod 32 .

[0041] A support plate 34 is fixedly mounted on the load-bearing seat 12 , and the other end of the adjusting threaded rod 32 is movably mounted on the support plate 34 via a bearing 35 .

[0042] A distance is set between the support plate 34 and the anti-collision guardrail frame 2. Since the support plate 34 and the anti-collision guardrail frame 2 are made of PVC material, which is flexible, the upper anti-collision guardrail frame 2 will be slightly bent when a vehicle collides, but it will not break. The spring 43 in the buffer device is compressed, but the compression displacement of the spring 43 is not large. The compression displacement of the spring 43 is less than the distance set between the support plate 34 and the anti-collision guardrail frame 2, thereby ensuring that the anti-collision guardrail frame 2 will not collide with the rear support plate 34 after the collision.

[0043] A plurality of guardrails 211 are installed in front of the anti-collision frame 21 . The provision of the guardrails 211 can strengthen the anti-collision frame 21 .

[0044] A warning light 213 is installed on the light board 212. The light board 212 is a long rectangular board. The warning light 213 uses the solar warning light 213 in the prior art. The base of the existing warning light 213 is provided with a nut and bolt structure. Multiple threaded holes can be opened on the light board 212. The warning light 213 can be fixed through the threaded holes, or a warning tape can be affixed to the light board 212. The alarm can warn pedestrians and vehicles to avoid collision with the guardrail.

[0045] The buffer assembly 4 includes an adjusting threaded rod 32 , an adjusting cylinder 33 , a spring 43 , a telescopic rod 44 and a limiting barrel. An anti-collision guide rod 41 is installed in front of the limiting baffle 22 , and the anti-collision guide rod 41 is movably installed in the adjusting cylinder 33 .

[0046] A contact plate 45 is provided at one end of the telescopic rod 44, and the telescopic rod 44 is connected to the contact plate 45. The telescopic rod 44 is movably installed in the limiting cylinder 46. The telescopic rod 44 is a cylindrical light rod. A mounting hole with a diameter slightly larger than the telescopic rod 44 is provided in the limiting cylinder 46 to ensure that the telescopic rod 44 can reciprocate in the limiting cylinder 46 along the axis direction of the limiting cylinder 46. The spring 43 is provided between the contact plate 45 and the limiting cylinder 46. When the vehicle is hit, the front anti-collision frame 21 transmits the force On the anti-collision guardrail frame 2, the anti-collision guardrail frame 2 transfers the force to the anti-collision protection tube 42, the anti-collision protection tube 42 compresses the spring 43 backward, and the telescopic rod 44 moves in the limit tube 46 to achieve impact buffering and avoid rigid collision between the vehicle and the anti-collision frame 21 during collision. The anti-collision guardrail frame 2 and the supporting base 11 are made of PVC. At this time, a slight deformation will occur at the connection between the anti-collision guardrail frame 2 and the supporting base 11, and the anti-collision guardrail frame 2 will bend relative to the supporting base 11.

[0047] The anti-collision frame 21 is fixedly installed inside the anti-collision guardrail frame 2 through a connecting rod 32. The bottom of the anti-collision frame 21 is welded to the inner wall of the anti-collision guardrail frame 2 through multiple connecting rods 32. The left and right sides of the anti-collision frame 21 are directly welded to the inner wall of the anti-collision guardrail frame 2 through the anti-collision frame 21 itself, so that the anti-collision frame 21 and the anti-collision guardrail frame 2 are integrated.

[0048] A slide groove 121 is provided on the load-bearing seat 12 , and the limit baffle 22 is movably installed on the slide groove 121 . A slider 122 is provided at the bottom end of the limit baffle 22 , and the slider 122 is movably installed in the slide groove 121 .

[0049] Working principle:

[0050] When adjusting the size of the isolation guardrail, the adjusting disk 31 is rotated, and the adjusting disk 31 drives the adjusting threaded rod 32. The adjusting threaded rod 32 rubs against the thread set on the inner wall of the adjusting cylinder 33. Under the action of the friction force, the adjusting cylinder 33 moves forward, and the adjusting cylinder 33 drives the limit baffle 22 fixedly connected thereto to move forward. The spring 43 between the anti-collision guide rod 41 and the anti-collision protection cylinder 42 is compressed, and the distance between the anti-collision frame 21 and the limit baffle 22 is shortened. The screw structure formed between the adjusting threaded rod 32 and the adjusting cylinder 33 has a self-locking function. If the adjusting disk 31 is not rotated in the reverse direction, the distance between the anti-collision frame 21 and the limit baffle 22 will only be shortened under the compression of external force and will not be lengthened;

[0051] When a collision occurs, the anti-collision frame 21 is compressed and buffered by the spring 43 between the anti-collision guide rod 41 and the anti-collision protection tube 42 to prevent the isolation guardrail from being damaged;

[0052] A smoke alarm 216 is arranged in the monitoring tank 215, which can be used to detect the exhaust gas and air quality discharged by the moving vehicles; a warning light 213 or a warning switch is fixed on the anti-collision frame 21 to warn vehicles and pedestrians.

[0053] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
