Abstract
Provided is a road protective fence. Generally, a driver cannot master a distance between a vehicle and an existing road protective fence accurately, and accordingly friction between the vehicle and the protective fence and traffic accidents are caused. The road protective fence comprises supporting rods (1), wherein the supporting rods are connected with lower-portion first cross rods (2) and lower-portion second cross rods (3), the lower-portion first cross rods are connected with one end of each of lower-portion fixing rings (4), and the other end of each of the lower-portion fixing rings is connected with the lower-portion second cross rods.
Description
Technical field
the utility model relates to a kind of road guard-rail.
Background technology
the common driver of existing road guard-rail grasps inaccurate and distance protective guard, causes rubbing with protective guard, causes traffic accident.
Summary of the invention
the purpose of this utility model is to provide a kind of road guard-rail with near distance warning device.
above-mentioned object realizes by following technical scheme:

the inside of described protection cylinder is vertical steel stay pipe, the outer cover of described vertical steel stay pipe has protection cylinder, protection cylinder outside is rubber sleeve, the other end of described protection cylinder connects top retainer plate, described vertical steel stay pipe connects and fixed lateral steel stay pipe, and described horizontal steel stay pipe is equipped with the first approach switch and the second approach switch.
connection top, one end first cross bar of described top retainer plate, the other end of described top retainer plate connects top the second cross bar, and described top the first cross bar connects top the second cross bar by tube connector.
each unit protective guard comprises 6 protection cylinder, and the first alarm is installed on the top of the 2nd protection cylinder, and the second alarm is installed on the top of the 5th protection cylinder.
the positive pole of the head end connecting valve power supply of the first described approach switch, the positive pole of described Switching Power Supply also connects the head end of the second approach switch, the end of the first approach switch connects the end of the second approach switch, the end of the first described approach switch connects the head end of the first alarm, the head end of the first described alarm also connects the head end of the second alarm, the end of the first alarm connects the end of the second alarm, the also negative pole of connecting valve power supply of the end of the first described alarm, Switching Power Supply connects 220V alternating current.
beneficial effect:
1. protection cylinder of the present utility model is with reflecting strips, has night the light can be reflective, prevents from having an accident because can't see.
protective guard of the present utility model is with proximity sensing device, when vehicle near time approach switch touch alarm, driver is away from protective guard in prompting, prevents from not preparing distance and causing rubbing with protective guard because grasping, and causes traffic accident.
support bar of the present utility model is steel work, prevents from breaking easily.
in circuit of the present utility model, adopt Switching Power Supply unsteady flow, directly receiving 220V power supply can use.
accompanying drawing explanation:
