Photovoltaic Construction Site Portable Toilet

The photovoltaic construction site portable toilet is a public sanitation facility that combines environmental protection concepts with modern technology, specifically designed for scenarios such as construction sites. It features self-sufficient energy supply, efficient wastewater treatment, and intelligent management.

Energy System

The photovoltaic construction site portable toilet is powered by solar photovoltaic panels, paired with energy storage batteries for off-grid operation. Some high-end models are also equipped with wind power complementary systems to ensure normal use during rainy weather. This design not only reduces reliance on the traditional power grid but also meets the environmental requirements of green construction sites.

Wastewater Treatment Technology

1. Biodegradation Technology: Microorganisms are used to decompose waste, reducing wastewater discharge and making it suitable for construction sites with high environmental protection requirements.
2. Vacuum Collection System: This system achieves an 80% water-saving rate, with a single flush volume of ≤0.5L. It is ideal for water-scarce areas or construction sites with limited water resources, effectively reducing water costs.

Intelligent Management Functions

1. IoT Remote Monitoring: Real-time monitoring of toilet stall usage status, water and electricity consumption, and other data enables managers to optimize resource allocation.
2. Automatic Disinfection Device: Utilizing ultraviolet light and spray disinfection, it automatically activates 3-5 times daily to ensure the toilet meets hygiene standards and reduces manual maintenance costs.

Application Scenarios and Material Selection

1. Structural Features: For construction sites, a simple steel frame structure is recommended, with high dustproof and sealing requirements to adapt to the dusty and complex environment of construction sites.
2. Material Suitability:
   • Metal Carved Panel: With a wind pressure resistance of ≥1.5kN/m², it is suitable for coastal areas or construction sites with strong winds.
   • Composite Insulation Panel: With a thermal conductivity of ≤0.024W/(m·K), it is suitable for northern regions in winter, ensuring a comfortable internal temperature in the toilet.

Manufacturers and Product Recommendations

1. Sichuan Zhongshun Jiaye: Supports 8cm thickened panels and offers a 1-year warranty, making it suitable for high-altitude areas such as Sichuan-Tibet.
2. Chengdu Liya Times: Its modular design allows for rapid deployment within 48 hours, with a light steel frame strength of Q235 standard, making it suitable for construction sites with tight schedules.
3. Chongqing Jinmuhe: Equipped with a vacuum self-priming wastewater treatment system, it excels in water-saving performance and is suitable for regions with limited water resources.

Acceptance Criteria

1. Check whether it has passed the GB/T 18092-2008 'Waterless Flush Toilet' certification to ensure compliance with national standards.
2. Conduct on-site tests to verify that the slip-resistant floor tile friction coefficient is ≥0.6 and the emergency call response time is ≤30 seconds to ensure user safety.
