Abstract
The invention relates to a buffer tube for a road guardrail. The buffer tube comprises an inner tube and an outer tube, wherein an annular magnet is wrapped on the outer surface of the inner tube; an electromagnet of which the magnetic pole is opposite to that of the annular magnet is fixedly connected to the inner surface of the outer tube; a space exists between the outer surface of the annular magnet and the inner surface of the electromagnet; the inner tube and the outer tube are fixedly connected by a plurality of rubber brackets; an infrared sensing device used for controlling the electromagnet is fixedly connected to the wall of the outer tube; a power supply device used for supplying power for the infrared sensing device and the electromagnet is arranged on the wall of the outer tube. According to the invention, the electromagnet of which the magnetic pole is opposite to that of the annular magnet is fixedly connected to the inner surface of the outer tube, thus the impact force is effectively reduced, and safety of the guardrail is improved.
Description
Technical field
The present invention relates to a kind of separator tube for road guard.
Background technology
Common road guard structure is simple; mainly for the protection of pedestrian and vehicular traffic; but common road guard tube connector is mainly hollow steel pipe composition; although firm; but because there is no pooling feature; so be easy to damage vehicle or pedestrian when colliding, very dangerous.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned Problems existing, provides a kind of separator tube for road guard, and solving ordinary road guardrail tube connector does not have buffer, causes the problem that safety is lower.
The technical solution adopted for the present invention to solve the technical problems is: a kind of separator tube for road guard, comprise inner and outer tubes, inner tube outer surface is enclosed with annular magnet, outer pipe internal surface is fixedly connected with the magnetic pole electromagnet contrary with annular magnet, gap is there is between annular magnet external surface and electromagnet inner surface, interior pipe is fixedly connected with by several rubber standoff with between outer tube, outer tube wall being fixedly connected with the infrared inductor for controlling electromagnet, outer tube wall being provided with the supply unit for powering to infrared inductor and electromagnet.
Further, supply unit is solar cell.
Further, electromagnet surface is provided with scratch resistant topping.
The invention has the beneficial effects as follows, the outer pipe internal surface of the separator tube for road guard of the present invention is fixedly connected with the magnetic pole electromagnet contrary with annular magnet, thus effectively reduces impact, promotes guardrail safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. interior pipes in figure, 2. outer tube, 3. annular magnet, 4. electromagnet, 5. support, 6. infrared inductor, 7. supply unit.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of separator tube for road guard as shown in Figure 1, comprise interior pipe 1 and outer tube 2, interior pipe 1 external surface is enclosed with annular magnet 3, outer tube 2 inner surface is fixedly connected with the magnetic pole electromagnet contrary with annular magnet 34, gap is there is between annular magnet 3 external surface and electromagnet 4 inner surface, interior pipe 1 is fixedly connected with by three rubber standoff 5 with between outer tube 2, outer tube 2 wall is fixedly connected with the infrared inductor 6 for controlling electromagnet 4, once infrared inductor 6 has detected that object is close, just control electromagnet 4 immediately to work, by the shock-absorbing capacity of the principle Promoting Layered Buffer pipe of magnet two like magnetic poles repel each other, effective reduction impact, outer tube 2 wall is provided with the supply unit 7 for powering to infrared inductor 6 and electromagnet 4, further, supply unit 7 is solar cell, further, electromagnet 4 surface is provided with scratch resistant topping, the outer pipe internal surface of separator tube for road guard of the present invention is fixedly connected with the magnetic pole electromagnet contrary with annular magnet 34, thus effectively reduce impact, promote guardrail safety.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
