DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 5 As shown, this embodiment proposes a municipal engineering guardrail cleaning device, including an adjustment box 1 and a cleaning mechanism 2, the cleaning mechanism 2 includes a rotating rod 201 rotatably mounted on the inner wall of the adjustment box 1, and the two ends of the rotating rod 201 are respectively fixedly connected with a turntable 202 and a worm gear 209. When the worm gear 209 rotates, the turntable 202 is driven to rotate through the rotating rod 201.

[0029] A protective shell 211 is fixedly connected to the upper surface of the adjustment box 1, and a first rotating motor 212 is fixedly connected to the outer surface of the protective shell 211. A worm 210 is installed on the upper surface of the adjustment box 1, and the worm 210 is meshed with the worm wheel 209. The shaft end of the worm 210 passes through the protective shell 211 and is fixedly connected to the output shaft of the first rotating motor 212.

[0030] By providing the first rotating motor 212 , when the first rotating motor 212 is driven to work, the worm 210 is driven to rotate, and the worm wheel 209 is rotated by the rotation of the worm 210 . When the worm wheel 209 rotates, the rotating disk 202 is driven to rotate through the rotating rod 201 .

[0031] The combination of the worm wheel 209 and the worm 210 has the effects of deceleration and self-locking, and can drive the turntable 202 to rotate. At the same time, the position of the turntable 202 after rotation can be limited, which is more practical.

[0032] The outer surface of the turntable 202 is hinged with two connecting rods 203 through a pin shaft, and the inner top wall of the adjustment box 1 is fixedly connected to two guide rails 204. The outer surface of each guide rail 204 is slidably connected with a slider 205, and the outer surfaces of the two sliders 205 are hinged with the two connecting rods 203 respectively.

[0033] When the turntable 202 rotates, the two sliders 205 can be moved on the two guide rails 204 respectively through the two connecting rods 203, and the two sliders 205 will move towards or away from each other.

[0034] The bottom surface of each slider 205 is fixedly connected to a connecting block 206, the bottom end of each connecting block 206 is installed with a servo motor 207, the output shaft end of each servo motor 207 is fixedly connected to a cleaning roller 208, the outer surface of the adjustment box 1 is installed with a mounting plate 213 and a nozzle assembly 215, and two hair dryers 214 are installed inside the mounting plate 213.

[0035] like Figure 2 As shown, the two connecting blocks 206 are respectively slidably connected to the two grooves opened on the bottom surface of the adjustment box 1. When the two sliders 205 move towards or away from each other, the two connecting blocks 206 can also be driven to move synchronously, so that the distance between the two cleaning rollers 208 can be adjusted, so that the device can provide the same quality of cleaning for guardrails of different sizes, thereby improving the practicality of the device.

[0036] It should be noted that the two servo motors 207 are controlled by a controller. When the controller controls the two servo motors 207 to work, the two cleaning rollers 208 can rotate simultaneously, thereby enabling the two cleaning rollers 208 to clean the guardrail.

[0037] And the direction of water spraying of the nozzle assembly 215 is the direction of the device's forward movement, so that the nozzle assembly 215 can first spray water on the guardrail, then wipe and clean the guardrail through two cleaning rollers 208, and finally blow off the water droplets on the guardrail as much as possible through the hair dryer 214, reduce the dust adhesion rate, and improve the cleaning quality.

[0038] Example 2

[0042] A water inlet 304 is installed at the top of the water tank 301, and a water outlet 305 is installed at the bottom of the water tank 301. The inner walls of the water inlet 304 and the water outlet 305 are both provided with sealing plugs. By setting the water inlet 304 and the water outlet 305, water can be added or drained into the water tank 301 in time.

[0043] The adjustment mechanism 4 includes a cavity 401 opened on the outer surface of the water tank 301, and the inner wall of the cavity 401 is rotatably connected to a threaded rod 403. One end of the adjustment box 1 is threadedly connected to the outer surface of the threaded rod 403. By setting the threaded rod 403, the height of the adjustment box 1 can be easily adjusted, thereby facilitating more thorough cleaning of guardrails of different sizes.

[0044] Two guide rods 404 are fixedly connected to the inner wall of the cavity 401, one end of the adjustment box 1 is slidably mounted on the outer surface of the two guide rods 404, the upper surface of the water tank 301 is fixedly connected to the second rotating motor 402, the shaft end of the threaded rod 403 passes through the cavity 401 and is fixedly connected to the output shaft of the second rotating motor 402. By setting the guide rods 404, the adjustment box 1 can be made more stable when moving, and by setting the second rotating motor 402, power can be provided to the threaded rod 403, thereby reducing the labor intensity of the staff.

[0045] A range meter 5 is installed on the outer surface of the water tank 301, and the inner wall of the range meter 5 is inlaid with transparent glass. By setting the range meter 5, the staff can grasp the remaining amount of water inside the water tank 301 in real time, so that the staff can add water to the water tank 301 in time.

[0046] A handle 6 is fixedly connected to the outer surface of the water tank 301, and four universal wheels 7 are installed on the bottom surface of the water tank 301. The handle 6 and the universal wheels 7 can be provided to enable staff to assist in pushing the device to move, thereby facilitating the cleaning of the municipal engineering guardrail.

When the second rotary motor 402 is started, it will drive the threaded rod 403 to rotate. Through the rotation of the threaded rod 403, one end of the adjustment box 1 can be moved upward or downward along the two guide rods 404. After adjusting the adjustment box 1 to a suitable position, the first rotary motor 212 can be driven to work according to the width of the municipal engineering guardrail to adjust the spacing between the two cleaning rollers 208, so that the same quality of cleaning can be provided for guardrails of different sizes. When the first rotary motor 212 is started, it will drive the worm 210 to rotate, and the rotation of the worm 210 will drive the worm wheel 209 to rotate. When the worm wheel 209 rotates, it will drive the rotating rod 201 and the turntable 202 to rotate. The rotation of the turntable 202 will cause the two sliders 205 to move along the corresponding guide rails 204 respectively through the two connecting rods 203, so that it can The two connecting blocks 206 can be moved toward or away from each other, so that the spacing between the two cleaning rollers 208 can be adjusted. After the two cleaning rollers 208 are adjusted to a suitable position according to the width of the guardrail, the water pump 302 can be driven to work first. When the water pump 302 is working, the water in the water tank 301 can be sprayed forward through the nozzle assembly 215 through the hose 303, and then the two servo motors 207 are driven to work synchronously, so that the two cleaning rollers 208 rotate synchronously to wipe and clean the guardrail, and then the two blowers 214 are driven to blow air downward. Finally, the staff can hold the handle 6 and push the device as a whole to move in the direction of the spraying water of the nozzle assembly 215, thereby realizing the following process: the guardrail is first sprayed with water through the nozzle assembly 215, and then the guardrail is wiped and cleaned through the two cleaning rollers 208, and finally the water droplets on the guardrail are blown off as much as possible through the blower 214, so as to reduce the adhesion rate of dust and improve the quality of cleaning.
