With the advancement of urbanization, urban construction has achieved significant results, but urban environmental issues still face challenges. As one of the urban environmental issues, there is currently no effective solution for dealing with flying catkins. Starting from solving this practical problem, the team has designed a modular urban environmental governance cleaning vehicle that is suitable for all seasons.The spraying type fly ash control drone has a dedicated controller to control its takeoff, landing, and route planning. The flying floc control drone is equipped with replaceable modular medicine water tanks and modular batteries. The modular mechanical arm can replace different adaptive devices to complete a variety of tasks, to meet the needs of urban environmental governance in the whole season. The electrostatic floc adsorption device carried can realize the function of using electrostatic adsorption principle to deal with flocs; The weeding device can achieve the function of repairing the height of urban roadside shrubs; The dust blowing device can achieve the function of cleaning debris on the green belt; The railing cleaning device can achieve the function of cleaning urban road railings. Designed a skylight structure that can be remotely controlled for sliding opening and closing, a locomotive rear cover structure that can be folded and opened, and a mechanical arm structure that can be folded and stored.
