Description

Technical Field

[0001] This utility model relates to the field of guardrail maintenance technology, and in particular to a guardrail maintenance device for national and provincial roads. Background Technology

[0002] Road and bridge guardrails serve to prevent vehicles from falling onto the road surface during traffic accidents. However, due to exposure to sun and rain, as well as corrosion from various dust and other contaminants, they are very prone to oxidation, which reduces their protective capabilities. In the event of a traffic accident, the guardrails often fail to provide the necessary protection against falling vehicles and to act as a buffer.

[0003] For example, a road and bridge guardrail cleaning and maintenance device with patent number CN213926019U includes a C-shaped cleaning frame and a first cleaning brush. A motor is installed at the edge of the upper surface of the C-shaped cleaning frame, and a transmission rod is fixedly connected to the output end of the motor. A first rotating rod is fixedly connected to one end of the transmission rod, and a first cleaning brush is fixedly connected to one end of the first rotating rod. However, the above document still has shortcomings. In use, the C-shaped cleaning frame is placed on both sides of the road and bridge guardrail, and then the motor is connected to an external power source. The operation of the motor causes the transmission rod to drive the transmission belt to work together, which in turn causes the first rotating rod and the second rotating rod to simultaneously drive the first cleaning brush and the second cleaning brush to rotate. The first cleaning brush and the second cleaning brush are in close contact with the road and bridge guardrail, resulting in a good wiping and cleaning effect. However, after cleaning with water, water droplets will remain on the surface. The water droplets will quickly absorb dust from the roadside, reducing the effectiveness of maintenance. The dust will be absorbed again shortly after cleaning. Summary of the Invention

[0004] This invention aims to solve the problem in the prior art where dust re-adsorbs shortly after cleaning, and provides a maintenance device for guardrails on national and provincial roads.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This national and provincial road guardrail maintenance device includes a frame and a national and provincial road guardrail. The national and provincial road guardrail is set inside the frame. A drying mechanism is set inside the frame. An adjustment component is set inside the frame. A water tank is fixedly connected to the upper surface of the frame. The water tank is fixedly connected to the input end of a liquid pump. The liquid pump is fixedly connected to the upper surface of the frame. A water pipe is fixedly connected to the output end of the liquid pump.

[0006] To further improve the system, the drying mechanism includes a fan fixed to the inner wall of the frame. A first air pipe is fixed above the fan, and a housing is fixed to the end of the first air pipe. The outer wall of the housing is fixedly connected to the frame. A heating plate is fixed inside the housing. A second air pipe is fixed to the right side of the housing. A hollow plate is fixed to the end of the second air pipe. The hollow plate is fixed to the inner wall of the frame, and an air nozzle is fixed to the surface of the hollow plate.

[0007] Further improvements include the addition of a water distribution plate fixedly connected to the end of the water pipe, with the outer wall of the water distribution plate fixedly connected to the support, and the outer wall of the water pipe fixedly connected to the frame and the support.

[0008] Further improvements include the bracket being fixedly connected to the inner wall of the frame via a support column, and water nozzles being fixedly attached to the surface of the water distribution plate.

[0009] To further improve the design, a motor is fixedly connected to the upper surface of the bracket, and a rotating rod is fixedly connected to the output shaft of the motor. The outer walls at both ends of the rotating rod are rotatably connected to the bracket via bearings.

[0010] To further improve the design, a cleaning ball, a cleaning rod, and a cleaning disc are fixedly connected to the outer wall of the rotating rod.

[0011] The beneficial effects of this utility model are as follows: Through the cooperation of the fan, the first air pipe, the box body, the heating plate, the second air pipe, the hollow plate, and the air outlet nozzle, the heating plate generates heat inside the box body. The fan blows air into the box body through the first air pipe. The hot air inside the box body enters the hollow plate through the second air pipe and is then sprayed out by the air outlet nozzle. This pushes the frame along the direction of the national and provincial road guardrails. The cleaning ball, cleaning rod, and cleaning disc clean the national and provincial road guardrails. The hot air blown out by the air outlet nozzle dries the surface of the national and provincial road guardrails, preventing water droplets from remaining on the surface of the national and provincial road guardrails. This prevents water droplets from quickly attracting dust from the roadside, thus increasing the importance of maintenance. After cleaning, the guardrails will not attract dust again for a short period of time. Attached Figure Description

Start the liquid pump 6, which draws water from the water tank 5, enters the water distribution plate 8 through the water pipe 7, and is discharged from the water nozzle 10, spraying it onto the provincial road guardrail 2. This, combined with the rotation of the cleaning ball 13, cleaning rod 14, and cleaning disc 15, cleans the provincial road guardrail 2. Start the blower. 301 and heating plate 304 generate heat inside the box 303. Fan 301 blows air into the box 303 through first air pipe 302. The hot air inside the box 303 enters the hollow plate 306 through second air pipe 305 and is then sprayed out by air nozzle 307. It pushes the frame 1, cleaning ball 13, cleaning rod 14 and cleaning disc 15 along the direction of the national and provincial road guardrail 2 to clean the national and provincial road guardrail 2. The hot air blown out by air nozzle 307 dries the surface of the national and provincial road guardrail 2 to prevent water droplets from remaining on the surface of the national and provincial road guardrail 2. The water droplets will quickly absorb the dust on the roadside, which increases the significance of maintenance. After cleaning, the dust will not be absorbed again for a short time.
