Core Viewpoint - The article discusses the development of a new modular grass-cutting boat designed for river maintenance in Hangzhou, which significantly improves efficiency and reduces labor costs in aquatic vegetation management [3][4]. Group 1: Innovation and Design - The grass-cutting boat is a collaborative innovation by the Hangzhou Urban Management Bureau and river maintenance units, aimed at addressing the challenges faced by maintenance workers [3]. - The design of the boat was inspired by the daily complaints of frontline maintenance personnel regarding the inefficiency of traditional manual grass cutting methods [3]. Group 2: Efficiency and Performance - Traditional manual grass cutting can cover an area of 200 to 400 square meters per day, while the new modular grass-cutting boat can handle 800 square meters per hour, representing a significant increase in operational efficiency [3]. - The boat requires only two maintenance personnel to operate, greatly reducing labor input and time costs [3]. Group 3: Versatility and Usability - The modular design of the grass-cutting boat allows it to adapt to various water depths and environments, making it effective in both narrow rivers and open lakes [4]. - The boat features a track-based cutting blade and a conveyor system that automatically transports cut grass to the work platform, alleviating the physical burden on workers [4]. - Its modular structure allows for easy transportation and quick assembly at different work sites, enhancing its operational flexibility [4].
