Structure of Baoding Outdoor Mobile Toilets

The structure of Baoding outdoor mobile toilets is centered around functional modular design, encompassing four major systems: structural load-bearing, sanitation treatment, on-site adaptability, and additional configurations. Details are as follows:

1. Structural Load-Bearing and Protection Module

This module provides physical support and environmental protection for the toilet. Wall materials include metal carved panels (galvanized steel base with anti-corrosion coating and relief layer, combining strength with landscape integration), aluminum-plastic panels (two layers of aluminum with a polyethylene core, lightweight but requiring framework support), or fiberglass-reinforced plastic (highly corrosion-resistant, suitable for complex curves or highly corrosive environments). The framework structure primarily uses light steel keels, which are hot-dip galvanized for rust prevention, with precise load distribution calculations to prevent deformation during transportation or use. High-strength aluminum alloy profiles, though more expensive, offer lighter weight and excellent corrosion resistance. The enclosure system employs light steel keel frameworks paired with composite sandwich panels (such as polyurethane or rock wool) for thermal insulation, with standardized interfaces reserved for subsequent functional module connections.

2. Sanitation Treatment and Environmental Protection Module

This module focuses on waste treatment and resource recycling. Treatment technology paths include:

• Packaging type: Immediate mechanical packaging of waste using biodegradable film, sealed into collection boxes, suitable for water-scarce or emission-restricted scenarios;
• Microbial degradation type: Decomposition of waste into carbon dioxide, water, and inorganic substances by specific bacteria, requiring ventilation and insulation systems to maintain bacterial activity;
• Vacuum suction type: Utilization of a vacuum pump to generate negative pressure, flushing with a small amount of water (0.5-1 liters per use),借鉴 (drawing on) train or aircraft toilet systems. Core functional modules include:
• Toilet and waste treatment integrated module: Incorporates water-saving toilets, small septic tanks, or packaging devices;
• Handwashing and water supply module: Integrates sinks, water-saving faucets, water storage tanks, or instant heating devices;
• Ventilation and lighting electrical module: Ensures user comfort and safety.

3. On-Site Adaptability Interface

This module enables rapid connection between the toilet and the site. Site connection is achieved through embedded parts, adjustable legs, or simple concrete piers for fixation. Service connection links to water supply interfaces, power access, and sewage pipes (such as septic tanks). Module combination supports parallel connection of multiple toilet units based on demand or the addition of management rooms to form small service units.

4. Additional Configurations

Depending on specific cases, toilets can be equipped with material and durability optimization designs, such as metal carved panels with a thickness of 8 cm and a service life of up to 20 years. Environmental adaptability designs include gable roofs suitable for temperature ranges from -40°C to room temperature and gray brick decorations at the base for enhanced stability. Internal facility expansions, such as squat toilets, water tanks, water heaters, and showerheads, meet diverse needs.

The above structure is based on general design logic, with specific implementations potentially adjusted according to manufacturer technical routes or the climate and usage scenarios in the Baoding area.
