[0046] The working principle and use process of the present invention are as follows: First, when construction and maintenance work is required on a highway, after the construction personnel lay the cone barrels at the location where the construction is required, they first determine the lane that needs to be constructed. If the fastest overtaking lane needs to be constructed, all three warning flashing lights 212 are turned on, so as to remind people in the most conspicuous way that the fast lane is under construction. If the middle lane is under construction, two warning flashing lights 212 are turned on to remind people that the middle lane is under construction. If the slowest lane is under construction, only one warning flashing light 212 needs to be turned on to alert people.

[0047] After the corresponding lights are turned on, the operator moves the installation barrel 1 to the construction location or the emergency lane. At this time, the operator unplugs the inflation gun 208 from the magnetic block 221, and then inserts the inflation gun 208 into the inflation end 214 outside the helium balloon 213. The operator then turns on the high-pressure air pump 203, and the high-pressure air pump 203 starts to work. The high-pressure air pump 203 extracts the helium inside the bottom compressed helium tank 202 through the air inlet pipe 204, and then transports the helium to the connection end 206 through the air outlet pipe 205. Then the helium will enter the gas transmission port 214 through the connection end 206. The inside of the hose 207 is finally filled into the inside of the helium balloon 213 through the inflation gun 208 connected to the helium balloon 213. At this time, a large amount of helium will quickly fill the inside of the helium balloon 213. When the pulling force of the helium balloon 213 can pull up the fixed block 211, the operator disconnects the inflation gun 208 from the inflation end 214 to release the helium balloon 213. At this time, the helium balloon 213 will float into the air and pull the fixed block 211 and the warning flash light 212 up to a certain height. At this time, the vehicles on the highway can observe the warning flash light 212 at a distance from the construction site.

[0048] And after the construction is completed in the first stage, the operator can pull down the helium balloon 213 through the cable 210. At this time, the helium balloon 213 can be slowly pulled to the position of the rubber sheet 220, and as the height continues to decrease, the operator can coil the cable 210 on the outside of the winding drum 215. When the fixing block 211 is wound to the position of the winding drum 215, the fixing block 211 can be clamped on the inner side of the fixing groove 216, and the warning flash light 212 can be clamped inside the light groove 217 to fix it. Then the operator deflates the helium balloon 213, so that the deflated helium balloon 213 is flattened on the top of the rubber sheet 220 for storage;

[0049] A large amount of helium gas is quickly filled inside the helium balloon 213. When the pulling force of the helium balloon 213 can pull up the fixed block 211, the helium balloon 213 is released. At this time, the helium balloon 213 will float into the air and pull the fixed block 211 and the warning flash light 212 up to a certain height. At this time, vehicles on the highway can observe the warning flash light 212 at a distance from the construction site, and the driver on the highway can know which lane is under construction at a distance, so that they can change lanes in advance to prevent a large number of vehicles from changing lanes and causing congestion after approaching the construction site. The high-level warning can not only warn the driver of the danger of construction ahead in advance, but also reduce the congestion caused by construction, thereby alleviating traffic pressure and improving commuting efficiency. The method of use is simple and efficient, and can cooperate with the road warning device to comprehensively ensure the safety of life and property of traveling vehicles and construction personnel, achieving multiple goals at one stroke.

[0050] Then, at the construction site, the clamping screw 312 can be screwed out from the inner side of the clamping slot plate 311 and the clamping screw hole 313, and the position restriction of the connecting rod 310 and the clamping slot plate 311 on the rotating rod 305 can be released, so that the rotating rod 305 can be rotated on the inner side of the rotating slot plate 302 by rotating the slot plate 304 and the rotating shaft 303, and the rotating rod 305 can be rotated to a horizontal ground position, and then the operator can pull the sliding plate 309, so as to still drive the telescopic rods 308 inside the multiple positioning slots 307 to extend upward, and then the sliding plate 309 can be raised to a certain height, and then the operator can move the alarm The slogan is hung on the top of the sliding plate 309. At this time, when the operator transfers the ground warning device such as the cone barrel over a short distance, he can first use the sliding plate 309 for ground warning, and then quickly move the ground warning device to the next construction site, and finally move the installation barrel 1 through the universal wheel 314 at the bottom of the moving seat 301, so as to ensure that there is a ground warning device to remind the driver during the entire movement process, and to ensure that there is still a warning device to protect the safety of the construction workers during the entire special process. In addition, some slow-moving devices are moved first, and then the installation barrel 1 with the universal wheel 314 is transferred to improve the overall transfer efficiency.

[0051] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention.
