Description

Hybrid Driven Type Remote Control Road Sweeping Car The present invention relates to a hybrid-driven remote-controlled road cleaning vehicle, and more specifically, to a hybrid-driven remote-controlled road cleaning vehicle capable of performing cleaning while driving on a road using electric energy, wherein a drive supply unit converts electric energy into hydraulic energy and provides driving force to the driving wheels, the suction guide cleaning unit, and the collection guide cleaning unit, respectively. Generally, local governments or road management agencies periodically remove foreign substances and fine dust accumulated on roads that have already been constructed and are in use to maintain and manage the road surface in a clean condition. In particular, waste disposal is considered very important in relation to urban aesthetics, and among these, cleaning roads and their surroundings is an indispensable task given the characteristics of a densely populated city. Accordingly, road cleaning vehicles that vacuum up debris are being used to enable road maintenance and management to be easily carried out with minimal manpower. However, conventional road cleaning vehicles are mainly composed of large vehicles, so they are only able to perform cleaning operations to remove foreign substances from the road surface on large roads where large vehicles can enter. Therefore, there is a problem in that, as it is difficult for conventional road cleaning vehicles to enter narrow alleys such as side roads, sanitation workers have to directly remove foreign substances such as trash, resulting in limitations in cleaning capacity compared to the excessive input of manpower. In addition, conventional road cleaning vehicles have the problem of causing respiratory diseases in workers due to exposure to dust generated during the cleaning process, as the workers are directly operated while on board. Therefore, there is a need to improve this.
