[0024] The utility model will be described in detail in the following in combination with the drawings:

[0025] As shown in Figure 1 and Figure 2 A washing and sweeping vehicle with guardrail cleaning function, comprising a vehicle body 1, a cleaning device 8 installed at the lower part of the vehicle body 1, and a clean water tank 2, a garbage can 5 and a power and transmission system 3 installed inside the vehicle body 1, the vehicle body 1 is provided with a guardrail cleaning device 11 at the front part, the guardrail cleaning device 11 is installed on the fixed frame 13 at the front part of the vehicle body through the connecting frame 12, the connecting frame 12 is connected with the mounting bracket 19 through the swing arm 20 and the lifting arm 21, the lifting arm 20 is provided with a lifting cylinder 24, the mounting bracket 19 is provided with a roller brush 22 and a roller brush motor 23 inside, and the mounting bracket 19 is provided with a cleaning system 17 at the upper part.

[0026] The cleaning system 17 includes nozzles 27, high-pressure water pipes 28, manual ball valves 29, and clean water tanks 2. The nozzles 27 are connected to the clean water tanks 2 via the high-pressure water pipes 28, manual ball valves 29, and high-pressure water pumps 7. There are at least two nozzles 27.

[0027] The fixed frame is equipped with a hydraulic valve 18, which is connected to the hydraulic oil pump 9, the lifting cylinder 24, and the roller brush motor 23 through the hydraulic oil pipe 32. The swing arm 20 is provided with a hinge hole at one end near the connecting frame, and a locking hole 25 and two limit bushings 26 at the other end. A tension spring 15 is provided at the connection between the swing arm 20 and the end of the lifting arm 21.

[0028] The connecting frame 12 is fixedly connected to the guardrail cleaning device 11 by a pin 14; the connecting frame 12 is fixedly connected to the front end of the fixing frame 13 by bolts; the rear end of the fixing frame 13 is fixedly connected to the front of the vehicle body 1 by bolts.

[0029] The vehicle body 1 has an operation control box 10 in the driver's cab, and also includes a fan 4 and a suction cup 6 located inside the vehicle body 1.

[0030] like Figure 2 As shown, when cleaning the right-side guardrail is required, firstly, remove the locking pin 16, manually swing the swing arm 20 to the right, insert the locking pin 16 into the right-end locking hole 25 of the connecting frame 12, and lock the swing arm 20 to the connecting frame 12; secondly, insert the limiting pin 30 into the rear limiting bushing 26 of the swing arm 20, and manually swing the lifting arm 21 to the right until the lower ear plate of the lifting arm 21 contacts the limiting pin 30; under the tension of the tension spring 15, the roller brush 22 and the lifting arm 21 always remain in the right-side swinging state; thirdly, manually rotate the mounting bracket 19 to the right, so that the two roller brushes 22 are located on the left side of the road guardrail, and insert the fixing pin 31 to fix the mounting bracket 19 to the lifting arm 21.

[0031] Start the power and transmission system 3 to make the hydraulic oil pump 9 work. By operating the control box 10 in the cab, control the hydraulic valve 18 to drive the lifting cylinder 24 to make the lifting arm 21, roller brush 22 and other components move up or down together to adjust the working height of the roller brush 22 so that the roller brush 22 adapts to the height position of the guardrail. Then, lower the sweeping device 8 and suction cup 6, make the blower 4 and high-pressure water pump 7 work, open the manual ball valve 29, and the nozzle 27 starts spraying water. Then make the sweeping device 8 and roller brush 22 rotate. Finally, start the vehicle body 1 to make the car move forward along the guardrail.

[0032] The high-pressure water sprayed from nozzle 27 washes the guardrail, which not only cleans the guardrail but also suppresses dust. The guardrail is brushed by roller brush 22, and the high-pressure water sprayed from the rear nozzle 27 can wash the guardrail a second time. The garbage and sewage on the road surface are sucked back into the garbage bin 5 by suction cup 6 under the action of fan 4, so as to avoid secondary pollution.

[0033] By operating the control box 10 in the cab and the manual ball valve 29, the operator can choose between traditional road sweeping and guardrail cleaning operations, making it very convenient to use.

[0034] like Figure 3 As shown, when the vehicle is not in operation and the guardrail cleaning device 11 needs to be retracted, the roller brush 22, the mounting bracket 19, and the lifting arm 21 are manually swung to the left. When the lifting arm 21 moves to the position of the limiting sleeve 26 of the swing arm 20, the limiting pin 30 is inserted into the limiting sleeve 26 at the front of the lifting arm 21 and the swing arm 20. In this way, the lifting arm 21 and the swing arm 20 are folded and fixed. At this time, the roller brush 22 is located in the middle of the front of the sweeper.

[0035] like Figure 4 As shown, when cleaning the left side guardrail is required, firstly, remove the locking pin 16, manually swing the swing arm 20 to the left, insert the locking pin 16 into the left end hole of the connecting frame 12, and lock the swing arm 20 to the connecting frame 12; secondly, insert the limiting pin 30 into the rear limiting sleeve 26 of the swing arm 20, and manually swing the lifting arm 21 to the left until the lower ear plate of the lifting arm 21 contacts the limiting pin 30; under the tension of the tension spring 15, the roller brush 22 and the lifting arm 21 always remain in the leftward swinging state; thirdly, manually rotate the mounting bracket 19 to the left, so that the two roller brushes 22 are located on the right side of the left side guardrail of the road, and insert the fixing pin 31 to fix the mounting bracket 19 to the lifting arm 21.

[0036] The remaining steps can be performed using the same method as the right-side guardrail cleaning operation described above, and then proceed with the left-side guardrail cleaning operation.

[0037] The parts not described in detail in this embodiment are existing technologies.

[0038] It should be noted that although the present invention has been described through the above embodiments, the present invention may have other various embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but these changes and modifications should all fall within the scope of protection of the appended claims and their equivalents.
