[0036] The above-mentioned unmanned vehicle part is existing technology and can be customized and produced by unmanned vehicle manufacturing units. The intelligent road guardrail cleaning system consists of a vehicle-mounted part and a vehicle external part. The vehicle external part includes: a cleaning system base frame 1, an intelligent roller brush cleaner 2, an intelligent spray cleaner 3, an intelligent ground brush dirt cleaner 4, an intelligent ground roller suction cleaner 5 and an intelligent ground spray sweep cleaner 6, which extend to the outside of the vehicle when cleaning the guardrail and retract into the inside of the vehicle when cleaning is completed. The vehicle-mounted part includes: a water tank, a water pump, a vacuum suction pump, and corresponding cables, water pipes, sewage suction pipes and wastewater and waste tanks, as well as a sensor system.

[0037] The cleaning system base frame 1 includes: a hydraulic rod 101, a hydraulic rod 102, a cleaning device base plate 103, a crescent groove 104, a rolling bearing 105, a slide rail 106, a sliding motor 107, a cleaning device hanging plate 108 and a waist groove 109; four crescent grooves 104 are symmetrically opened at the left and right ends of the cleaning device base plate 103, and rolling bearings 105 are slidably installed in the crescent grooves 104, and the other ends of the rolling bearings 105 are respectively hinged to the telescopic ends of the hydraulic rod 101 and the hydraulic rod 2 102, and the fixing ends of the hydraulic rod 101 and the hydraulic rod 2 102 are The ends are respectively hingedly installed on the inner wall of the car body of the unmanned vehicle, a slide rail 106 is provided on the top of the slide rail 106, and a sliding motor 107 is slidably installed on the front and rear sides of the slide rail 106, and a washer hanging plate 108 is installed on the sliding motor 107. The front and rear sliding motors 107 are operated to adjust the distance between the front and rear washer hanging plates 108, so that the front and rear washer hanging plates 108 can be placed on both sides of the guardrail for cleaning. The washer hanging plate 108 also includes a plurality of waist-shaped grooves 109.

[0038] When the cleaning system base frame 1 is in use, the fixed ends of the first hydraulic rod 101 and the second hydraulic rod 102 are hinged to the inner compartment wall on the right side of the vehicle body moving forward, and the cleaning device substrate 103 is movably connected through the telescopic ends of the first hydraulic rod 101 and the second hydraulic rod 102, so that the cleaning device substrate 103 can be freely extended and retracted. When the first hydraulic rod 101 and the second hydraulic rod 102 extend or retract, their telescopic ends can slide up and down in an arc on the crescent groove 104. The cleaning device substrate 103 is connected to the vehicle through the first hydraulic rod 101 and the second hydraulic rod 102. And through the extension and retraction of the first hydraulic rod 101 and the second hydraulic rod 102, and the support of the sensor system, the cleaning system is pushed to the position of the road guardrail to be cleaned for cleaning, and after the cleaning work is completed, it retracts into the vehicle body.

The retracting and releasing motor 408 is mounted on the fixed seat 407. The telescopic end of the fourth hydraulic rod 409 is vertically mounted with an angle adjusting motor 410. The output end of the angle adjusting motor 410 is provided with an L-shaped row brush and scraper 411.

[0048] When the above intelligent floor dirt scrubber 4 is in use, for the sewage and dirt that have been cleaned by the front cleaning system and fallen onto the ground, especially the ground directly under the guardrail, with the support of sensors, relying on the extension hydraulic rod 101 and the hydraulic rod 2 102, the brush scraping plate on the walking balance trolley 406 is extended to the ground at the bottom of the guardrail at an angle of 45 degrees. By extending the hydraulic rod 3 402, the brush scraping plate is driven to push and scrape the sewage and dirt on the ground to the opposite road surface, and then it is cleaned by the ground brush roller 508 in the intelligent floor rolling suction scrubber 5 suspended on the scrubber hanging plate on the opposite side, sucked into the suction pipe, and sent to the sewage and dirt tank. Moreover, when the above intelligent floor dirt scrubber 4 is in use, the positions of the intelligent floor dirt scrubbers 4 installed on the front and rear scrubber hanging plates are staggered (can be staggered front and back) to prevent interference and collision between the two. In the case of uneven ground, the spring telescopic rod 3 405 can press the walking balance trolley 406 against the ground for cleaning operations.

[0049] When cleaning, the vertically erected hydraulic rod 3 402, driven by the retracting and extending motor 408, is lowered towards the guardrail. At this point, the hydraulic rod 3 402 that is basically parallel to the ground and slightly lower extends out, pushing the brush scraping plate towards the ground at the bottom of the guardrail. One end of the brush scraping plate has a short board at a right angle. An angle adjustment motor 410 is installed at the top of the brush scraping plate. The angle adjustment motor 410 can rotate the brush scraping plate and push the brush scraping plate to the guardrail cleaning area. With the support of sensors, the brush scraping plate is pushed to the guardrail pier in a state parallel to the guardrail, and the brush scraping plate is continuously pushed forward to the opposite road surface, and then retracted to the bottom of the guardrail crossbar. With the support of sensors and the angle adjustment motor 410, the brush scraping plate is adjusted inward to an angle of 45 degrees. At this time, the brush scraping plate forms a 45-degree inclined plane with the guardrail. At this time, the hydraulic rod pushes the brush scraping plate along the direction of the guardrail, pushing the garbage all the way. When approaching the bottom of the next guardrail pier crossbar, the angle adjustment motor 410 timely pushes the brush scraping plate to rotate 45 degrees on the ground. At this time, the brush scraping plate is already parallel to the guardrail. The hydraulic rod 3 402 quickly pushes the brush scraping plate forward, crosses the crossbar at the bottom of the guardrail pier, reaches the opposite road surface, pushes the garbage to the road surface opposite the guardrail, and then quickly retracts the hydraulic rod 3 402 to continue the next cleaning process.

[0050] Example 4

[0051] On the basis of the above-mentioned Embodiment 3, this embodiment further includes the following: The intelligent floor rolling and sucking cleaner 5 includes: a fourth fixing member 501, a third sliding block 502, a fourth telescopic spring 503, a second fixing rod 504, a fifth telescopic spring 505, a sewage suction shell 506, a sewage suction hood 507, a brush roller 508, a roller motor 509, a cleaning comb 510, a water accumulation tank 511, a first sewage suction port 512, and a second sewage suction port 513; The third sliding block 502 is slidably installed in the waist-shaped groove 109. A fourth telescopic spring 503 is provided between the third sliding block 502 and the fourth fixing member 501. The fourth fixing member 501 is arranged on the cleaner hanging plate 108. A second fixing rod 504 is vertically installed on the third sliding block 502. A fifth telescopic spring 505 is provided at the lower end of the second fixing rod 504. The lower end of the fifth telescopic spring 505 is provided with a sewage suction shell 506. A brush roller 508 is rotatably installed in the sewage suction shell 506. The shaft end of the brush roller 508 is connected to the output end of the roller motor 509. The roller motor 509 is installed outside the sewage suction shell 506. The cleaning comb 510 is obliquely arranged in the sewage suction shell 506 and is located above the left of the brush roller 508. The water accumulation tank 511 is integrally formed at the bottom of the left end of the sewage suction shell 506. The sewage suction hood 507 covers the outside of the sewage suction shell 506. The bottom end face of the sewage suction hood 507 is higher on the left and lower on the right, and the left side is slightly higher than the ground, and the right side is close to the ground. The sewage suction shell 506 is respectively provided with the first sewage suction port 512 and the second sewage suction port 513. The two first sewage suction ports 512 and the second sewage suction port 513 are respectively arranged close to the cleaning comb 510 and the water accumulation tank 511, and the two first sewage suction ports 512 are located on the front and rear side walls of the sewage suction shell.

[0052] During the above use, the front end (the direction of vehicle travel) of the sewage suction shell 506 is relatively close to the brush roller 508, and the rear end of the sewage suction shell 506 is relatively far from the brush roller 508 but close to the ground. Through the above-mentioned cleaning comb 510 similar to a hard scraper of a wooden comb, the dirt attached to the brush end of the brush roller 508 can be scraped off. When the motor drives the brush roller 508 to rotate, the bristles bring up the sewage and dirt on the ground. Part of it falls into the tail of the sewage suction hood 507 near the ground at the rear of the brush roller 508 and is sucked into the sewage suction pipe through the second sewage suction port 513. Another part of the sewage and dirt that rises to the top of the brush due to the situation enters the sewage suction hood 507. As the brush roller 508 continues to roll forward, part of the sewage and dirt reaches the cleaning comb 510 part along with the rolling of the brush. Under the extrusion of the cleaning comb 510 and the sewage suction shell 506, it detaches from the brush and is sucked into the sewage suction pipe through the two first sewage suction ports 512, and then is sucked into the sewage and dirt box.

[0053] When the brush roller 508 rotates and picks up sewage and dirt, the suction air inside the suction hood 507 helps it to rise, and it continues to enter along with the rotation of the brush. As the contact surface between the brush and the suction hood 507 becomes tighter and tighter, the sewage and dirt are instantly squeezed out and are promptly sucked away by the suction air through the two suction ports, namely suction port one 512 and suction port two 513, and sent to the sewage and dirt box.

[0059] Based on the above Embodiment 5, this embodiment further includes the following: It further includes an intelligent control system, and the intelligent control system includes a camera, various sensors, a pre-processor, a micro-processor, a control output unit and an actuator.

[0060] In summary, the present utility model further includes the following usage process:

[0061] 1. The driverless fully automatic road guardrail cleaning machine is a brand-new, intelligent road guardrail cleaning machine that replaces manual labor. The driverless vehicle can preset the driving route, starting from the station → the guardrail cleaning operation section → returning to the station. The driverless vehicle has a tachograph to instantaneously record and store the vehicle driving conditions. The driverless vehicle can instantaneously transmit the vehicle condition, road condition, cleaning operation, and abnormal conditions. The driverless vehicle is controlled by the station center and instantaneously accepts and implements the new plan of the center.

[0062] 2. Vehicle-mounted cleaner part: Vehicle-mounted part: It has a water pump, a blower, a suction pump, a water tank, a sewage and dirt tank, a power supply cable, water pipes, air pipes, sewage suction pipes, and a pipe bridge, as well as a special cleaning system for cleaning road guardrails and a device for extending / retracting the base frame for carrying the cleaning system. There is also mainly an unmanned operation intelligent system that supports the above-mentioned automatic cleaning and extension and retraction.

[0063] Instructions for using the vehicle-mounted cleaner part:

[0064] The driverless fully automatic road guardrail cleaning machine travels to the guardrail section to be cleaned according to the preset.

[0065] ① Automatically adjust to the special limited vehicle speed for cleaning operations. At the guardrail section of the intersection, automatically adjust the preset operation distance between the vehicle and the guardrail during driving.

[0066] ② Automatically stop, and the hydraulic rod group automatically pushes the cleaning system base frame 1 upward and outward. At this time, the front and rear cleaner hanging plates (hanging plate 1 and hanging plate 2) on the cleaning system base plate are in a parallel state.

[0067] ③ With the support of the sensor, the vehicle positions the road guardrail at the midline between hanging plate 1 and hanging plate 2. If the distance between hanging plate 1 and hanging plate 2 is too narrow, with the support of the sensing system, start the synchronous servo motors on hanging plate 1 and hanging plate 2 to make hanging plate 1 and hanging plate 2 slide outward respectively to expand the distance between the two plates to meet the requirements for guardrail cleaning. The guardrail and the cleaner are automatically adjusted. When the distance is appropriate, with the support of the sensor, the vehicle moves forward. The guardrail enters the middle gap between hanging plate 1 and hanging plate 2, and the guardrail cleaning starts. If there are green plants or other objects blocking both ends of the guardrail and the two groups of hanging plates cannot be inserted into the guardrail, with the support of the sensor, the vehicle automatically drives to a suitable position parallel to the guardrail and stops, automatically raises the hydraulic rod groups 1 and 2, and pushes the cleaning system base frame 1 outward to the middle position above the guardrail. Automatically lower it. At this time, hanging plate 1 and hanging plate 2 are respectively on both sides of the guardrail. After automatically adjusting the appropriate cleaning distance between the hanging plate and the guardrail, the cleaning starts.

[0068] ④ When there is an obstacle ahead, forcing the installed washers to be under pressure, the washers equipped with servo motors and hydraulic rods can automatically retract quickly with the support of sensors to avoid hard collisions. The washers with springs installed at the rear end of the groove of the washer hanging plate 108 can also retract to buffer the pressure after being stressed. When the pressure on the washing system base frame 1 reaches a certain amount, or the pressure transmitted to each washing / processing device reaches a certain amount, the intelligent control system will execute a pause operation or parking procedure.

[0069] ⑤Synchronously, the intelligent roller brush cleaner 2 starts working with the support of the sensor, the water nozzle opens according to the height of the guardrail, the water nozzle automatically adjusts the angle, sprays water at the contact part between the brush roller 508 and the guardrail railing, and the brush roller 508 rotates under the drive of the servo motor to wash the guardrail railing. Similarly, the intelligent roller brush cleaner 2 installed on the cleaning system hanging plate 2, with the support of the sensor, is also doing the same cleaning work, cleaning the other side of the guardrail.

[0070] ⑥ Synchronously, the intelligent spray cleaner 3 located behind the intelligent roller brush cleaner 2, with the support of sensors, synchronously aims at the guardrail railing, especially the railing with a foundation, to spray water for cleaning. Similarly, the intelligent spray cleaner 3 fixed on the cleaning system hanging plate 2, with the support of sensors, is also doing the same work, cleaning the other side of the guardrail. There are many styles of guardrails, including vertical bars, horizontal bars, inclined bars, and various forms. With the support of sensors, the water nozzle can automatically adjust the up and down position and left and right angles of the nozzle for cleaning.

[0071] ⑦ Synchronously, the intelligent floor brush cleaner 4 located behind the intelligent sprinkler has a walking balance trolley 406 that is pressed against the ground under the pressure of the spring on the cleaning system base frame 1 and moves on the road surface by relying on the pulley 110 at the bottom of the workbench. The walking balance trolley 406 has a hydraulic rod, which is connected to a brush scraper, and the brush scraper is in an "L" shape.

[0072] With the support of the sensor, the brush scraper installed at the front end of the hydraulic rod quickly moves toward the ground of the guardrail seat in parallel with the guardrail, presses the ground and pushes forward quickly, crosses the guardrail, and reaches the position of the intelligent roller suction cleaning device hung on the cleaning device hanging plate 2 on the opposite side of the road.

[0073] After the brush scraper reaches the opposite predetermined road surface, it is quickly adjusted to a 45-degree angle inward with the support of sensors and servo motors, and quickly pushed forward along the guardrail crossbar to reach the guardrail seat in front.

[0074] Before the brush scraper reaches the front guardrail seat, with the support of the sensor and servo motor, the brush scraper quickly rotates outward and becomes parallel to the guardrail crossbar, and continues to be pushed quickly toward the opposite road surface. After reaching the road surface cleaned by the opposite intelligent roller brush cleaner 2, it quickly retracts to its own road surface.

[0075] Then, the next round of cleaning begins.

[0076] Similarly, the intelligent ground brush and dirt cleaner 4 installed on the opposite cleaning device hanging plate 2 is also doing the same job, pushing the sewage and dirt under the bottom of its own guardrail to the opposite road surface for cleaning by the cleaner on the opposite side.

[0077] ⑧ Synchronously, behind the intelligent ground brush and dirt cleaner 4 is the intelligent ground rolling and suction cleaner 5. Under the pressure of the hydraulic rod and spring, its brush roller 508 rotates closely against the ground to clean sewage and dirt. With the support of sensors, according to the amount of sewage and dirt on the road surface, it can automatically adjust the suction force of the suction pump and the rotation speed of the brush roller 508. Similarly, the intelligent ground rolling and suction cleaner 5 installed on the opposite cleaning device hanging plate 2 is also doing the same job, cleaning the sewage and dirt on the ground on the other side of the guardrail.

[0078] ⑨ Synchronously, behind the intelligent ground rolling and suction cleaner 5 is the intelligent ground spraying and sweeping cleaner 6. With the support of sensors, it can timely adjust the up and down angles of the water spray nozzles. According to the ground conditions, it can adjust the water spraying intensity appropriately. Similarly, the intelligent ground spraying and sweeping cleaner 6 installed on the opposite cleaning device hanging plate 2 is also doing the same job, cleaning the opposite road surface to make it cleaner and more hygienic.

[0079] ⑩ Intelligent control system, sensors are installed on the driverless vehicle. There are sensors on the front, rear, left and right of the cleaning system base frame 1 of the vehicle-mounted part.

[0080] Safety protective cover 7, there is a warning light on the safety protective cover 7. After the guardrail cleaning operation is completed, in the preset program, the control system will operate automatically in reverse, and the base frame will retract into the interior of the carriage. The vehicle will automatically turn around and return to the station along the original route.

[0081] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention according to the above disclosure shall fall within the protection scope of the claims.
