At the beginning of the year, Renhe Square in Yuhang District, Hangzhou was officially put into use. This new landmark, which integrates leisure, entertainment and fitness, quickly became a popular destination for the residents in the area. To safeguard this "happiness right at our doorstep", the Urban Management Bureau of Yuhang District and Renhe Subdistrict broke through the traditional constraints of sanitation work and innovatively implemented a new smart cleaning model of "manual + sweeping + cleaning in one". They introduced the unmanned sweeping machine "Dolphin 15" from Xunling Intelligent Technology Co., Ltd., a wholly-owned subsidiary of Jinlu Environment, to reshape the sanitation operation process of the square with the power of technology, and use meticulous management to ensure the "clean and beautiful life" of the people.
01 Technological Breakthrough
From "Human-Based Tactics" to "Human-Machine Collaboration"
Traditional square cleaning relied on manual labor, which was not only labor-intensive and inefficient, but also difficult to achieve full-area, no-corner coverage. To solve this problem, Renhe Street, based on the actual needs of the people, actively embraced technological changes and constructed a "human-machine collaboration, complementary advantages" intelligent cleaning system. Among them, the Dolphin 15 unmanned sweeping machine independently developed by Xunling Intelligent became the core equipment of this new model.
The Dolphin 15 is equipped with a L4-level autonomous driving system and integrates multiple sensor perception technologies. It has core capabilities such as 360° no-blind-area environmental perception, autonomous decision-making in complex road conditions, and stable operation in all weather conditions. It has a sleek design and a small turning radius, making it particularly suitable for semi-enclosed and open scenarios such as squares, parks, and sidewalks for precise cleaning.
02 Precise Operations
Full Coverage, No Omissions
Under the new model, Renhe Street scientifically divides the operation areas and clearly defines the responsibilities:
The Dolphin 15 unmanned sweeping machine: It conducts two full-area cleanings of the square every day, efficiently removing common garbage such as dust, fallen leaves, and paper scraps. A single unit significantly improves the operation efficiency.
The floor cleaning vehicle: It performs a deep polishing of the ground once a day, precisely removing stubborn stains, making the square floor consistently clean and shiny.
The manual cleaning team: They mainly focus on the hygiene blind spots that the Dolphin 15 cannot reach, the internal parts of the fruit bins, and the crevices, completing the detailed work and filling the gaps of the equipment, achieving true full-area coverage.
This "large-scale coverage by unmanned equipment + precise spot cleaning by humans" operation mode not only significantly reduces the labor intensity of sanitation workers but also achieves the goals of "full-area coverage, meticulous cleaning, and long-term management".
03 Remarkable Benefits
Public Praise, Environmental Renewal
The square is cleaner now, and it's more comfortable to bring children to play ~
Technology makes life better!
Since the new cleaning mode has been in operation, the environmental appearance of Renhe Square has undergone a qualitative leap. The ground is clean and free of debris, the edges are dust-free, and the facilities are free of stains. The overall appearance has been completely renewed. The clean and excellent environment not only enhances the happiness and satisfaction of the public but also becomes a vivid window of the refined management level of Renhe Street.
Jinliu Takes on the Responsibility: Empowering Beautiful China with Cutting-Edge Technology
The smart cleaning practice of Renhe Square is an illustration of Jinli Environment's unmanned equipment assisting in urban refined management. In the future, Jinli Environment and Xunling Intelligent will continue to deeply explore the "artificial intelligence + sanitation" field, with more advanced products and more complete solutions, to empower more urban blocks, squares, and industrial parks, using technological power to safeguard the cleanliness of cities and countryside, and contribute Jinli strength to building a beautiful China where humans and nature coexist harmoniously.
