The surface of the air pump 7 is provided with a control button for the person to inflate the air pump 7. The air pump 7 is also called an air pump, and is a device for exhausting air from an enclosed space or adding air from an enclosed space, in the present application, the air pump 7 may be an electric air pump, that is, an air pump powered by electric power, and generates air pressure by continuously compressing air through electric power, so as to inflate the ventilation pipeline 6, which is a well-known technology and will not be described herein in detail.
The top interval of vent line 6 is provided with air pocket 8, and air pocket 8 is multistage, because air pocket 8 has the segmentation, consequently air pocket 8 can not directly shrink like the direct air pocket and grow into strip after bleeding, and air pocket 8 of multistage can be because the segmentation is whole to vent line 6 internal contraction after bleeding for when flexible board 2 encircles in atress pole 4 shrink, air pocket 8 presss from both sides between the flexible board 2 of multiturn, makes air pocket 8 be difficult for rocking everywhere. Alternatively, the material of the air bag 8 can be an impact-resistant material such as PA, and the PA material is polyamide, so that the air bag has high mechanical strength, high pressure bearing and stretching performance, and meanwhile, the air bag also has the advantages of heat resistance, wear resistance, shock absorption, weak acid and alkali resistance, good electrical insulation, easy dyeing and the like. The air bag 8 made of the PA material can have stronger vertical force after being inflated, can resist friction and sunlight irradiation after being paved on a road, and is convenient for smearing the color so as to improve the conspicuity degree of the air bag 8.
The flexible guardrail belts 9 are connected between the air bags 8, the flexible guardrail belts 9 can be used as railings of road guardrails, the flexible guardrail belts 9 can be driven to rise along with rising of the air bags 8, and the flexible guardrail belts can be erected along the paved flexible plate 2 after rising to form a longer guardrail belt, so that the guardrail has the interception function of a conventional guardrail and can be used rapidly in emergency. The surface of flexible guardrail area 9 is offered a plurality of vent 14 of array, and optionally, vent 14 can be triangle-shaped and offer, and after flexible guardrail area 9 risen, the wind that blows to flexible guardrail area 9 can be along vent 14 through flexible guardrail area 9, reduces the area of contact of wind and flexible guardrail area 9, reduces the influence of strong wind to flexible guardrail area 9, alleviates the effort of strong wind to flexible guardrail area 9. Therefore, through the cooperation setting of vent line 6, air pump 7 and air pocket 8, personnel can be through air pump 7, utilize the quick messenger each air pocket 8 of vent line 6 to aerify vertically to drive the rise of flexible guardrail area 9, utilize flexible guardrail area 9 to replace the railing of road guardrail, quick installation goes out emergent guardrail, simultaneously, can utilize carousel 10, quick withdraw the guardrail, have convenience and practicality.
One side of the air pump 7 is connected with an air pressure sensor 12, and the inlet end of the air pressure sensor 12 is communicated with the ventilation pipeline 6, and the air pressure sensor 12 is arranged to detect the air pressure in the ventilation pipeline 6 when the air pump 7 inflates the ventilation pipeline 6 so as to judge the inflation amount of the air pump 7 in the ventilation pipeline 6, so that the inflation of the ventilation pipeline 6 and the air bag 8 is in a stable and safe air pressure range, the air pump 7 is prevented from excessively inflating the ventilation pipeline 6, the excessive deformation of the air bag 8 caused by the excessive inflation is avoided, and the decrease of the impact resistance of the air bag 8 is prevented. The surface of the air pressure sensor 12 is provided with a display panel by which a person determines the air pressure in the ventilation duct 6 and the air bag 8. The air pressure sensor 12 is an instrument for measuring the absolute pressure value of the air in the enclosed space, and is suitable for detecting the air pressure in the ventilation pipeline 6 and the air bag 8, which is a known technology and will not be described in detail herein.
The air pump 7's opposite side is connected with aspiration pump 19, and the entrance point of air pressure sensor 12 communicates in vent line 6, and the setting of aspiration pump 19 can be after the road guardrail is used to the completion, when the air in vent line 6 and air pocket 8 need be taken out, take out the air in vent line 6 and the air pocket 8 through aspiration pump 19 fast, improves the recovery efficiency of emergency road guardrail. It is noted that the connection between the ventilation pipe 6 and the air pump 19 is provided with a one-way valve, and the one-way valve is arranged so that the ventilation pipe 6 can not leak air directly through the air pump 19 after being inflated, but the one-way valve is opened by suction after the air pump 19 is started, and air is pumped out of the ventilation pipe 6 in one direction. The surface of the air pump 19 is provided with a control button for the air pumping operation of the air pump 19 by personnel. The air pump 19 is provided with an air suction nozzle and an air exhaust nozzle which are respectively arranged in and out, and can continuously form vacuum or negative pressure at the inlet, and micro positive pressure is formed at the air exhaust nozzle; the working medium is mainly an instrument of gas, also called a micro vacuum pump, the working principle of the air pump 19 is the same as that of the micro vacuum pump, and the diaphragm in the pump is made to reciprocate through the circular motion of a motor, so that air in the ventilation pipeline 6 is compressed and stretched to form vacuum, namely negative pressure, a pressure difference is generated between the air pumping port and the outside atmospheric pressure, and the gas is pumped into the pump cavity and then discharged from the air outlet under the action of the pressure difference. Because the pumping hole or the pumping vent can form pressure difference with the external atmosphere, the large vacuum pump does not need lubricating oil and vacuum pump oil, does not pollute and block the ventilation pipeline 6, and has the advantages of small volume, no maintenance and the like, which is a known technology and is not repeated here.
