When the top surface of the clamping block 308 contacts the bottom surface of the conical fixing block 304, the resilience of the spring 1 306 effectively applies an upward force to the connecting plate 305, so that the clamping block 308 can be firmly abutted against the bottom surface of the conical fixing block 304.

[0033] The outer surface of the slide bar 307 is sleeved with a second spring 309 , and both ends of the second spring 309 are fixedly connected to the connecting plate 305 and the clamping block 308 respectively.

When the top surface of the conical slider 303 contacts the bottom surface of the conical fixed block 304, the spring three 310 can be compressed into the grooves of the conical slider 303 and the conical fixed block 304.

[0035] A guard plate 311 is hinged on the outer surface of the connecting plate 305 , and a support rod 312 is hinged on the outer surface of the guard plate 311 . The support rod 312 effectively supports the guard plate 311 .

[0038] The inner wall of the water tank 401 is fixedly connected to a connecting pipe 402, the outer surface of the connecting pipe 402 is fixedly connected to the bearing layer 1 and the road base body 2, and a sealing ring is fixedly installed between the water tank 401 and the connecting pipe 402, thereby effectively preventing rainwater in the water tank 401 from overflowing.

The setting of the nozzle can effectively atomize and spray rainwater, effectively increasing the range of rainwater spraying, so that the rainwater can more comprehensively cover the surface of the road base body 2.

[0040] The water pump 403 in this application is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0041] Working principle: First, fix the fixed base plate 301 on the surface of the bearing layer 1 through the fixing parts, and then insert the fixing rod on the top surface of the fixed base plate 301 into the blind hole on the bottom surface of the connecting plate 305. In the process of pressing down the connecting plate 305, the two clamping blocks 308 are effectively pushed to slide relative to each other in the inner wall of the connecting plate 305 according to the slope on the surface of the conical fixing block 304. At this time, the spring 1 306 and the spring 2 309 will be squeezed and deformed. When the connecting plate 305 drives the clamping block 308 to move down to the bottom surface of the conical fixing block 304, the spring 2 309 is no longer squeezed by its own force. The rebound force pushes the two blocks 308 to move closer to each other for reset. The blocking of the block 308 by the conical fixing block 304 prevents the connecting plate 305 from moving upward again, thereby achieving the rapid fixation of the connecting plate 305. At the same time, the rebound force of the spring four 314 effectively supports the support rod 312, so that the guard plate 311 is closely attached to the surface of the road base body 2 for supporting work, effectively avoiding the situation that the soil layer in the road base body 2 is lost outward and collapsed due to long-term weathering, rain impact and vehicle movement. When the guard plate 311 needs to be disassembled, repaired and replaced, it can be replaced by When the locking cam 308 is in the unlock state, the locking cam 308 is in the unlock state, and the locking cam 308 is in the unlock state, so that the locking cam 308 is locked. 04, at this time, the connecting plate 305 is continuously moved upward and the resilience of the second spring 309 is cooperated to make the block 308 slide back and forth in the inner wall of the connecting plate 305 according to the surface slope of the conical slider 303 and the conical fixed block 304, effectively making the connecting plate 305 detach from the top of the fixed bottom plate 301. When the surface of the road base body 2 is overheated, by turning on the water pump 403, the rainwater inside the water tank 401 can be effectively pumped into the spray pipe 404, and the rainwater is sprayed on the surface of the road base body 2 through the nozzle at one end of the spray pipe 404 to cool it down, thereby further improving the service life of the road base body 2.
