[0031] The outer surface of the second sprocket 204 is fixedly connected to a transmission rod 205, and the outer surface of the transmission rod 205 is rotatably connected to the guard plate body 201. The outer surface of the transmission rod 205 is transmission-connected to a warning cloth 206, and the rotation of the second sprocket 204 can effectively make the warning cloth 206 on the surface of the transmission rod 205 roll intermittently.

[0032] The inner wall of the guard plate body 201 is fixedly connected with a motor 207, and the outer surface of the guard plate body 201 is equipped with a control button of the motor 207. The motor 207 is a common electrical device in the prior art, and this application will not go into too much detail about its model or internal structure. It can also be replaced by other power sources. The output end of the motor 207 is fixedly connected to the first sprocket 202. The setting of the motor 207 can effectively drive the warning cloth 206 to perform intermittent transmission, thereby warning multiple warning messages.

[0033] A transparent plastic plate 208 is fixedly connected to the inner wall of the guard plate body 201, and a cover plate 209 is fixedly connected to the inner wall of the guard plate body 201. The surface content of the warning cloth 206 can be effectively observed through the setting of the transparent plastic plate 208, and the transparent plastic plate 208 can better protect the warning cloth 206 from being damaged by external factors. By opening the cover plate 209, the parts in the warning mechanism 2 can be effectively inspected and repaired at a later stage.

[0034] Please refer again Figure 3 An adjustment mechanism 3 is arranged above the fixed base plate 1, and the adjustment mechanism 3 includes a screw rod 301, one end of which is rotatably connected to the guard plate body 201. The rotational connection between the screw rod 301 and the guard plate body 201 can effectively play a role in fixing and limiting the screw rod 301.

[0035] The outer surface of the lead screw 301 is threadedly connected with a first slider 302. The outer surface of the first slider 302 is slidably connected with the guard plate body 201. A heightening plate 303 is fixedly connected to the outer surface of the first slider 302. By rotating the lead screw 301, the chain 203 can be effectively moved up and down.

[0036] A second slider 304 is fixedly connected to the outer surface of the heightening plate 303. A slide bar 305 is slidably connected to the inner wall of the second slider 304. One end of the slide bar 305 is fixedly connected to the guard plate body 201. A rotating handle 306 is fixedly connected to the outer surface of the lead screw 301. By providing the rotating handle 306, the lead screw 301 can be rotated more conveniently. By providing the slide bar 305, the heightening plate 303 can move up and down more stably.

[0037] Please refer to again Figure 4 , a fixed block 4 is fixedly connected to the outer surface of the guard plate body 201. A bidirectional threaded rod 5 is rotatably connected to the inner wall of the fixed block 4. A threaded barrel 6 is threadedly connected to the outer surface of the bidirectional threaded rod 5. By providing the fixed block 4, the bidirectional threaded rod 5 can be effectively fixed and limited.

[0038] A first limit block 7 and a second limit block 8 are slidably connected to the outer surface of the threaded barrel 6. The outer surfaces of the first limit block 7 and the second limit block 8 are fixedly connected to the guard plate body 201. By rotating the bidirectional threaded rod 5 to make the upper and lower threaded barrels 6 slide into the inner wall of the second limit block 8, every two adjacent guard plate bodies 201 can be effectively spliced.

[0039] Working principle: The fixed bottom plate 1 is fixed to the enclosure location through the fixing member, and at the same time, the guard plate body 201 is fixed above the fixed bottom plate 1. At this time, the second limiting block 8 on the outer surface of the other group of guard plate bodies 201 contacts the outer surface of the first group of guard plate bodies 201. Then, the bidirectional threaded rod 5 is rotated. The rotation of the bidirectional threaded rod 5 drives the threaded cylinder 6 to slide up and down in the inner wall of the first limiting block 7 until the threaded cylinder 6 slides into the second limiting block 8 on the outer surface of the other group of guard plate bodies 201 to complete the splicing of each group of guard plate bodies 201. After the splicing is completed, the motor 207 is operated to rotate the first sprocket 202. The rotation of the first sprocket 202 drives the chain 203 to drive. The driving of the chain 203 drives the second sprocket 204 to rotate. The rotation of the second sprocket 204 drives the transmission rod 205 to rotate. The rotation of the transmission rod 205 drives the warning cloth 206 to drive for scrolling warning. When the guard plate body 201 is heightened according to different track enclosure operations, at this time, the rotating handle 306 is rotated to rotate the lead screw 301. The rotation of the lead screw 301 drives the first slider 302 to slide upward in the inner wall of the guard plate body 201. The sliding of the first slider 302 drives the heightening plate 303 to move upward until the heightening plate 303 moves upward to the required height and then the urban track is enclosed again. Therefore, the operation of this device is simple and flexible, and it can cope with different urban roads.
