Description

Autonomous Road Sweeper with Improved Suction Intake Structure and Control Method Thereof The present invention relates to an autonomous road surface cleaning device, and more particularly to a road surface cleaning device with an improved suction unit. Generally, debris such as fallen leaves and sand (hereinafter referred to as "road debris") discarded on general roads, highways, parking lots, large industrial complexes, airport runways, and large sports fields is mainly cleaned by road cleaning vehicles equipped with cleaning tools. Furthermore, even if road debris is removed by the aforementioned road sweeper, fine dust and vehicle tire residue remain attached to the road surface. These particles are scattered whenever vehicles pass, becoming a major cause of air pollution. FIG. 4 is a schematic structural diagram of a road surface cleaning device according to the prior art. In the suction part of the conventional road surface cleaning device (30), the front windbreak plate (31) is openable and closable, so when opened due to bulky debris, the suction power is reduced due to the decrease in wind pressure, and there is a problem that residual dust is not sucked in and passes through the rear gap due to the decrease in wind pressure. The inventors of the present invention have made research efforts to solve the problems of such conventional road surface cleaning devices and have completed the present invention relating to a road surface cleaning device having an improved suction port structure in which wind pressure is not reduced even when foreign matter passes through. FIG. 1 is a schematic diagram of an autonomous road surface cleaning device with an improved suction unit structure according to a preferred embodiment of the present invention. FIG. 2 is a flowchart of a control method for an autonomous road surface cleaning device with an improved suction unit structure according to another preferred embodiment of the present invention.
