[0032] Please refer to Figures 1 to 3 , an automatic cleaning device for train roof insulators provided in an embodiment of the present application includes a brush roller 1, a supporting square tube 2, a supporting rectangular tube 6 and a robotic arm 7; the supporting square tube 2 and the supporting rectangular tube 6 are fixedly connected in an L shape; the brush roller 1 is rotatably connected to the end of the supporting square tube 2 away from the supporting rectangular tube 6, and is driven to rotate by a driving mechanism; a nozzle assembly is provided on the supporting square tube 2 to spray water on the brush roller 1 and the insulator to be cleaned; the robotic arm 7 is connected to the end of the supporting rectangular tube 6 away from the supporting square tube 2 to drive the brush roller 1 to move its position.

[0033] According to some embodiments of the present application, the drive mechanism includes a servo motor 81, a reducer 82, and a transmission shaft 83. The output end of the servo motor 81 is connected to the input end of the reducer 82, and the output end of the reducer 82 is connected to the transmission shaft 83 via a sprocket chain 84. The transmission shaft 83 is provided on the supporting square tube 2, and the brush roller 1 is connected to the transmission shaft 83. The servo motor drives the reducer to move, and the reducer transmits power to the sprocket chain, which then drives the transmission shaft to rotate, thereby driving the brush roller to rotate at high speed to clean the insulator.

[0034] According to some embodiments of the present application, the driving mechanism is arranged inside the supporting square tube 2 and the supporting rectangular tube 6. Since there is a cavity inside the supporting square tube and the supporting rectangular tube, the driving mechanism can adopt a hidden design scheme. Specifically, the servo motor 81 and the reducer 82 are arranged inside the supporting rectangular tube 6, the sprocket chain 84 is arranged inside the supporting square tube 2, and the transmission shaft 83 is installed at the end of the supporting square tube 2 through a bearing with a sealing ring. The sprocket chain 84 includes two sprockets and a chain, one of which is connected to the output end of the reducer 82, and the other sprocket is connected to the middle of the transmission shaft 83. The upper and lower ends of the transmission shaft 83 extend outside the supporting square tube 2 so that the two ends of the transmission shaft 83 are fixedly connected to the brush roller 1. The driving mechanism adopts a hidden arrangement, which can avoid the influence of dust, water stains, and dirt during the equipment cleaning process, greatly increasing the service life and extending the maintenance cycle.

[0035] According to some embodiments of the present application, the brush roller 1 includes a roller body 11 and bristles disposed on the outer circumference of the roller body 11. The roller body 11 is connected to the drive mechanism. Specifically, the roller body 11 is cylindrical and is bolted to a drive shaft 83 extending from the supporting square tube 2. The brush roller 1 is located at the front end of the supporting square tube 2. The drive shaft is driven to rotate, thereby driving the brush roller to rotate at high speed.

[0036] According to some embodiments of the present application, the bristles are made of high-quality PA nylon filaments. The brush roller uses nylon filaments, which have excellent wear resistance and resilience, and are resistant to high temperatures, acids, and alkalis.

[0037] According to some embodiments of the present application, the nozzle assembly includes an upper nozzle 5 and a lower nozzle 3, which are respectively arranged on the upper and lower sides of the supporting square tube 2. By arranging the upper nozzle and the lower nozzle on the supporting square tube, water can be sprayed on the brush roller above the supporting square tube through the upper nozzle, and water can be sprayed on the brush roller below the supporting square tube through the lower nozzle.

[0038] According to some embodiments of the present application, the upper nozzle 5 and the lower nozzle 3 are water-vapor atomizing nozzles. These nozzles are connected to the water pipe and the air pipe, respectively. The hollow cavity structure within the nozzle creates a siphon effect, producing atomized water mixed with water and gas. This water is then sprayed by a fan-shaped nozzle at the front end onto the brush roller and the insulator being cleaned. This design utilizes a high-pressure water siphon structure, resulting in minimal water consumption and preventing large-scale water accumulation on the roof, which could result in secondary pollution.

[0039] According to some embodiments of the present application, the supporting square tube 2 and the supporting rectangular tube 6 are welded carbon steel structures. This design approach is simple, compact, strong, and durable. The robotic arm 7, which drives the supporting square tube 2 and the supporting rectangular tube 6, is not prone to damage to the train's roof components, allowing for flexible and maneuverable access to narrow roof spaces to perform various cleaning operations. The upper end of the supporting rectangular tube 6 is secured to the end of the robotic arm 7 via a flange.

[0040] According to some embodiments of the present application, the automatic cleaning device for train roof insulators further includes an image detection unit 4 for detecting the position of a train, and the robotic arm 7 moves according to the train position information fed back by the image detection unit 4 to determine the cleaning and photographing positions.

[0041] According to some embodiments of the present application, the image detection unit 4 is integrated into a housing, which is fixedly connected to the intersection of the supporting square tube 2 and the supporting rectangular tube 6. Specifically, the image detection unit 4 includes a laser rangefinder and a camera (neither of which is shown in the figure). The laser rangefinder and camera are disposed within the housing, and openings for the laser rangefinder and camera are provided on the side walls of the housing to facilitate measurement and photography.

[0042] When the locomotive stops steadily, the upper computer gives the vehicle model and allows the action. The robotic arm enters the ranging posture and the locomotive on the track starts to move forward from the standby position. The laser rangefinder stops after detecting the position of the roof ranging feature point. The on-track system starts to calculate the current car position and height deviation, and after feeding back to the PLC, it moves to the precise positioning feature point again to take a picture. After the picture is taken, the position deviation is fed back to obtain the precise position deviation. The PLC obtains the data, performs precise calculations, and determines the cleaning and photo-taking positions based on the previously set reference position.

[0043] The automatic cleaning device for train roof insulators in this embodiment has the following specific working process: 1. The mechanical arm 7 drives the brush roller 1 at the end to the front of the insulator to be cleaned; 2. The servo motor 81 located in the supporting square tube 6 drives the sprocket chain 84 to move, driving the transmission shaft 83 built into the supporting square tube 2 to rotate, thereby driving the brush roller 1 at the front end to operate at high speed; 3. At this time, the mechanical arm 7 automatically guides the brush roller 1 to slowly approach the insulator to be cleaned, and the upper nozzle 5 and lower nozzle 3 located on the supporting square tube 2 are opened simultaneously, and the generated atomized water is sprayed onto the insulator and the brush roller 1 that is operating at high speed, performing a full-scale, no-dead-angle cleaning operation on the insulator. 4. After cleaning, the mechanical arm 7 is retracted, the brush roller 1 stops rotating, the upper nozzle 5 and lower nozzle 3 are closed simultaneously, and the device is in standby mode.

[0044] The automatic cleaning device for train roof insulators in this embodiment takes into account the complex equipment layout on train roofs and the umbrella structure of high-voltage insulators, and has been specifically designed. A concealed servo motor and its transmission structure drive the high-speed rotation of the brush. Combined with a siphon-effect water vapor atomizing nozzle, it can reach into the narrow space of the roof equipment to perform comprehensive, no-dead-angle cleaning of the insulators, significantly improving the cleaning efficiency and quality of train roof insulators. The device is lightweight and compact, easy to manufacture, and maintain and replace. For severely contaminated insulators, a dedicated cleaning fluid and brush roller can be used in combination for even better cleaning results.

[0045] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
