Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, and in particular relates to a portable cleaning device for a subway contact rail protective cover. Background Art

[0002] The development of urban rail transit is an indispensable component of modern urbanization. As cities expand and population density increases, simple rail transit can no longer meet the growing demand for travel. Consequently, various forms of rail transit, including subways, light rail, and intercity railways, have emerged. Underground contact rails, a form of power supply within the railway system, primarily serve urban rail transit, providing a continuous and stable power supply for trains. Protective covers primarily protect the contact rails from dust and insulation, but due to long-term exposure to the open air or dust carried by trains, they develop a layer of difficult-to-clean dirt, significantly impacting their service life, insulation performance, and appearance. This also affects the performance of the contact rails themselves. With subway maintenance limited to three to four hours at night, daily manual cleaning is time-consuming, labor-intensive, and difficult. Therefore, improvements are necessary to address these issues. Utility Model Content
