Mobile Toilets in Xinjiang Parks
The design of mobile toilets in Xinjiang parks features adaptability to extreme environments, diverse functions, and modular, easy-to-maintain structures.
Structural and Material Design: Given the significant temperature variations between day and night in Xinjiang, the metal frames of the mobile toilets are constructed from low-temperature tough steel, capable of withstanding stress changes caused by seasonal transitions and preventing structural deformation or damage due to temperature fluctuations. The exterior panels are made of composite sandwich materials with thermal insulation layers, effectively reducing heat transfer and maintaining stable internal temperatures. The floor incorporates moisture-proof padding and reflective films to prevent ground moisture and reflect heat, enhancing insulation. The roof is designed with a slope to facilitate the sliding of rain and snow, reducing the pressure from accumulated snow and forming an air insulation layer to further improve thermal insulation. The door and window seals are made of ethylene propylene diene monomer rubber, with labyrinth-style sealing designs at the joints to effectively prevent air infiltration and enhance sealing and insulation.
Internal Environment Control: A combination of passive and active methods is employed. Passive methods, such as high side-window natural ventilation, utilize natural airflow for ventilation and air exchange. Active methods, such as integrated small ventilation devices, provide forced ventilation when natural ventilation is insufficient, ensuring fresh internal air. In water-scarce or waterless areas, some facilities utilize microbial degradation technology, decomposing solid waste through constant-temperature anaerobic fermentation chambers to reduce water consumption and environmental pollution.
Sewage Treatment and Energy Supply: Sewage treatment systems are tailored to regional infrastructure differences, equipped with either pulverizing sewage lift pumps or vacuum collection systems. Some newer systems incorporate membrane filtration technology to enhance sewage treatment efficiency and quality. Energy supply is diversified, with photovoltaic films integrated into the roof surfaces to convert solar energy into electricity. Energy storage devices use lithium-ion systems or high-end capacitors to store excess electricity. Some facilities are also equipped with micro wind turbines to generate electricity from wind energy, meeting the power demands of the mobile toilets.
Modular Design and Maintenance: The overall design is modular, allowing for disassembly based on standard container dimensions for easy transportation and installation. On-site, quick connectors facilitate water and electricity connections, with replaceable functional components and standardized interfaces ensuring interchangeability and reducing maintenance costs and difficulty. Daily maintenance focuses on freeze protection and corrosion prevention, with self-regulating heating cables used in the piping system to prevent pipe freezing and hot-dip galvanizing treatment for metal connectors to enhance corrosion resistance.
