Abstract

The utility model relates to the field of anti-collision guardrails, in particular to an anti-collision guardrail for a road. In the prior art, a reflective strip is easy to adhere dirt to influence the warning reflective effect and lose the warning effect, and the warning effect of the reflective strip is far insufficient for an automobile running at a high speed. According to the technical scheme, the anti-collision guardrail for the road comprises a supporting frame, a hollow guardrail body and the like. The supporting frames are jointly and fixedly connected with a plurality of hollow guardrails. Before a vehicle approaches to the hollow guardrail, the surface of the reflective stripe is wiped and cleaned through the wet bristles on the cleaning ring, the warning effect of the reflective stripe is guaranteed, and it is guaranteed that when lamplight on the vehicle irradiates the reflective stripe, a driver can clearly see the positions of the reflective stripe and the hollow guardrail at the first time so as to determine the boundary of a road, and the road traffic safety is guaranteed. And the situation that the vehicle runs out of the road boundary and collides with the hollow guardrail is avoided.

Description

Technical Field

[0001] The utility model relates to the field of anti-collision guardrails, in particular to an anti-collision guardrail for roads. Background Art

[0002] With the booming economy and the improvement of people's living standards, more and more people choose to travel by private car instead of public transportation. During the peak travel time during holidays such as the Golden Week, many people have to travel at night due to congestion on highways or time arrangements. However, due to cost control, environmental protection requirements and maintenance engineering considerations, there is a general lack of nighttime lighting devices on highways. Relying solely on headlights for lighting undoubtedly poses a great hidden danger to nighttime driving safety. Especially in rainy and foggy weather, the guardrails on both sides of the road are difficult to see clearly, and it is easy to hit the guardrails during driving due to visibility problems.

[0003] In response to this situation, reflective strips for warning are often installed on highway guardrails. However, due to lack of maintenance, the reflective strips are easily attached with dirt, which affects the warning reflective effect and loses its warning function. For cars traveling at high speeds, the warning effect is far from enough. Utility Model Content

[0004] In order to overcome the shortcomings of the problems mentioned in the background, the utility model provides an anti-collision guardrail for a road.

[0009] Optionally, each water collecting bucket is provided with a filter.

[0010] Optionally, the filter screen on the water collecting bucket is made of metal.

[0011] The beneficial effects of the utility model are as follows: before a vehicle approaches the hollow guardrail, the utility model wipes and cleans the surface of the reflective strip by using the wet bristles on the cleaning ring to ensure the warning function of the reflective strip and ensure that when the light on the vehicle shines on the reflective strip, the driver can immediately see the positions of the reflective strip and the hollow guardrail to determine the boundary of the road and avoid driving out of the road boundary and colliding with the hollow guardrail.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0020] Example

[0021] A road crash barrier, such as Figure 1-Figure 5 As shown, it includes a support frame 1 and a hollow guardrail 2; all support frames 1 are bolted together with at least three hollow guardrails 2;

[0022] It also includes a water collecting bucket 3, a connecting pipe 4, an electrically driven slider 5 and a cleaning ring 6; the uppermost hollow guardrail 2 is connected to two water collecting buckets 3; every two adjacent hollow guardrails 2 are connected to each other by two connecting pipes 4; each hollow guardrail 2 is provided with four symmetrically distributed slide rails 2a; each slide rail 2a is slidably connected to an electrically driven slider 5; all electrically driven sliders 5 on the same side of the same hollow guardrail 2 are commonly fixed to a cleaning ring 6, and there is a spacing between the cleaning ring 6 and the hollow guardrail 2 on the corresponding side, and a number of densely packed bristles are arranged on the inner side of the cleaning ring 6; the hollow guardrail 2 is provided with six water holes 2b distributed in a circular array, and the water holes 2b cooperate with the cleaning ring 6.

[0023] It also includes a water-saving ring 101, an elastic tube 102, a counterweight ring 103, an electric push rod 104 and a circular ring 105; each hollow guardrail 2 is slidably connected to two symmetrically distributed water-saving rings 101; each water-saving ring 101 is provided with six water-through holes 101a distributed in a circular array; each water-saving ring 101 is provided with two symmetrically distributed elastic tubes 102; the elastic tube 102 has elastic expansion and contraction capabilities, and each elastic tube 102 has a built-in spring with a small elastic coefficient; each hollow guardrail 2 is bolted to two symmetrically distributed electric push rods 104; the telescopic part of each electric push rod 104 is fixedly connected to a circular ring 105; each elastic tube 102 close to the circular ring 105 is provided with a counterweight ring 103.

[0024] It also includes a ball 201; each hollow guardrail 2 is provided with four symmetrically distributed slide grooves 2c; each elastic cylinder 102 close to the ring 105 is provided with two symmetrically distributed balls 201, and each ball 201 is respectively set to a damping sliding connection with the slide groove 2c on the corresponding side. Through the damping sliding connection between the ball 201 and the slide groove 2c, the sliding resistance of the elastic cylinder 102 is increased, the speed of the elastic cylinder 102 and the counterweight ring 103 approaching the ring 105 is reduced, the cleaning interval is increased, and water resources are saved.

[0025] It also includes protrusions 202; each slide groove 2c is provided with a plurality of spaced protrusions 202, and the protrusions 202 are in contact with the ball 201, and the protrusions 202 increase the sliding resistance of the ball 201 through the protrusions 202, thereby increasing the recovery resistance of the ball 201 and the elastic tube 102, and slowing down the recovery speed of the elastic tube 102.

[0026] Each water collecting bucket 3 is provided with a filter screen, and the fallen leaves are intercepted by the filter screen on the water collecting bucket 3 to prevent the fallen leaves from clogging the water collecting bucket 3.

[0027] The filter on the water collecting bucket 3 is set to be made of metal material to increase the service life of the filter.

[0028] The utility model works specifically as follows:

[0029] When assembling the hollow guardrail 2, water is injected from the water collecting bucket 3 into the hollow guardrail 2 of the uppermost layer, and flows to the hollow guardrails 2 of the middle and lower layers through the connecting pipe 4, so that the water fills all the hollow guardrails 2, ensuring that the hollow guardrail 2 has sufficient water. Moreover, when the hollow guardrail 2 is put into use, rainwater is collected by the water collecting bucket 3, reducing the frequency of manual water injection and reducing the work intensity of workers; and the hollow guardrail 2 filled with water has a stronger anti-collision ability than the general hollow guardrail 2, thereby improving the anti-collision performance of the hollow guardrail 2;

[0030] At the same time, a sensor is installed fifty meters near the hollow guardrail 2 on the road, and a controller is assembled on the support frame 1, and the sensor is connected to the controller, and the controller controls the sliding of the electric drive slider 5 and the extension and retraction of the electric push rod 104, so as to wipe and clean the reflective strip 001 later;

[0031] Under normal conditions, water hole 102b is blocked by elastic tube 102, and water hole 102b is disconnected from water hole 2101a. When a vehicle approaches 50 meters from hollow guardrail 2, the sensor senses the vehicle passing by, and then transmits the information to the controller, which controls the telescopic part of electric push rod 104 to drive ring 105 close to counterweight ring 103, and applies a driving force to counterweight ring 103, so that counterweight ring 103, under the action of inertia, compresses elastic tube 102 toward the direction of reflective strip 001, so that elastic tube 102 pushes water-saving ring 101 close to water hole 102b, so that water hole 102b is connected to water hole 2101a, so that the water flowing inside hollow guardrail 2 can pass through water hole 2101a, water hole 102 in sequence. b is sprayed toward the inner side of the cleaning ring 6, thereby wetting the bristles on the inner side of the cleaning ring 6, and then the electrically driven slider 5 drives the cleaning ring 6 to move on the slide rail 2a toward the reflective strip 001. When it moves to the middle of the reflective strip 001, it returns to the initial position, so that the two cleaning rings 6 on the same hollow guardrail 2 move back and forth toward and away from each other on the hollow guardrail 2. In this way, before the vehicle approaches the hollow guardrail 2, the surface of the reflective strip 001 is wiped and cleaned by the wet bristles on the cleaning ring 6 to ensure the warning function of the reflective strip 001 and to ensure that when the light on the vehicle shines on the reflective strip 001, the driver can see the position of the reflective strip 001 and the hollow guardrail 2 at the first time to determine the boundary of the road and avoid driving out of the road boundary and colliding with the hollow guardrail 2.

[0032] It should be noted that when the counterweight ring 103 is separated from the circular ring 105 under the force of inertia, the counterweight ring 103 loses the driving force exerted by the circular ring 105, and the counterweight ring 103 gradually approaches the circular ring 105 under the elastic restoring force of the spring inside the elastic tube 102. Since the elastic coefficient of the spring inside the elastic tube 102 is small, the counterweight ring 103 has no external force to push it, and it has a certain gravity of its own, resulting in the speed at which the counterweight ring 103 approaches the circular ring 105 is much lower than the speed at which the counterweight ring 103 approaches the reflective strip 001. In this process, even if multiple vehicles pass by the sensor continuously, the controller controls the electric push rod The telescopic part of 104 drives the circular ring 105 to approach the counterweight ring 103 many times, but it cannot touch the counterweight ring 103, so that the water hole 1 2b and the water hole 2 101a will not be frequently in a connected state in a short period of time, until the counterweight ring 103 is restored to the initial position under the elastic reset force of the spring inside the elastic tube 102, and the circular ring 105 can touch the counterweight ring 103, thereby repeating the above steps to make the water hole 1 2b and the water hole 2 101a connected for the second time, avoiding the reflective strip 001 from being cleaned many times in a short period of time, causing waste of water resources, increasing the frequency of artificial water injection, and increasing work intensity.
