Mobile Toilet Composition Drawing Explanation

The composition drawing explanation of mobile toilets mainly includes rendering drawings, CAD processing drawings, configuration lists, and material lists. Its core structure adopts a modular design, supporting flexible customization of dimensions, easy installation, and不受场地限制 (unrestricted by site conditions).

1. Basic Frame Structure

The base frame of a mobile toilet typically employs a frame-type steel welding process, using high-strength steel (such as square tubes or angle steel) to construct the main support structure, ensuring overall stability. The base frame design must consider load-bearing requirements, usually equipped with anti-slip floors and drainage slopes. Some high-end models integrate septic tanks or sewage collection systems. The modular design of the frame allows for adjustments in dimensions according to site needs. For example, the standard size for a single toilet cubicle is 1.1m×1.1m, but it can be expanded into multi-cubicle combinations by adding or removing modules.

2. Wall and Enclosure Materials

Wall materials primarily consist of lightweight high-strength panels, with common options including:

1. Color-coated steel plates: Composed of galvanized steel plates and polyurethane sandwich layers, they offer fire resistance, moisture resistance, sound insulation, and are lightweight (approximately 10-15kg/㎡), facilitating easy transportation and installation.
2. Fiberglass-reinforced plastic (FRP): Using glass fiber-reinforced plastic as the base material, it exhibits strong corrosion resistance, suitable for coastal or high-humidity environments, but costs about 20%-30% more than color-coated steel plates.
   Wall thickness typically ranges from 50-100mm, connected to the frame via clips or bolts, with some designs adopting detachable structures for easy maintenance.

3. Mobile Devices and Functional Modules

1. Mobile wheel sets: High-load-bearing universal wheels (diameter ≥150mm) are installed at the bottom, paired with brake devices to enable switching between fixed and mobile states. At least four wheel sets are required for moving a single toilet cubicle.
2. Ventilation system: An exhaust fan (air volume ≥300m³/h) and intake grille are integrated at the top, creating negative pressure ventilation. Some models are equipped with activated carbon filter layers to reduce odors.
3. Lighting and electrical: LED moisture-proof lamps (illuminance ≥150lux) and waterproof sockets are used. The power supply can be connected to the mains or configured with solar panels (power ≥200W) and battery packs.

4. Drawing Types and Customization Support

1. Rendering drawings: Display the 3D appearance and color scheme of the mobile toilet, assisting clients in confirming the design style.
2. CAD processing drawings: Include precise dimensions, connection methods, and assembly sequences for each component, such as base frame welding joint diagrams and wall installation sectional views.
3. Configuration list: Clearly specifies functional module options (such as whether to add urinals or barrier-free facilities) and specifications for electrical and plumbing systems.
4. Material list: Details the specifications of steel sections, panel thickness, hardware model numbers, etc., facilitating cost calculation and procurement.

The modular design enables mobile toilets to quickly respond to different scenario requirements. For example, scenic spots can choose wood-grain color-coated steel plates to enhance aesthetics, while construction sites prioritize wear-resistant FRP materials.
