Mobile Portable Toilet Structure

The structure of mobile portable toilets mainly falls into two categories: those based on water storage tanks and those modified from water storage barrels, both achieving mobility and functional integration through modular design.

Structure Based on Water Storage Tanks

1. Mobile Base Design
   A plastic pallet is used as the foundational structure, with universal wheels installed at all four corners to ensure overall flexibility in movement. The pallet must have sufficient load-bearing capacity to support the weight of the water storage tank, toilet, and other components.

2. Modular Assembly of Water Storage Tanks
   Recycled water storage tanks have their tops cut open, and two tanks are stacked vertically and secured with self-tapping screws to form a double-layer water storage structure. The upper tank is used for storing clean water, while the lower tank collects wastewater, enabling independent water resource circulation.

3. Functional Area Cutting and Installation
   A rectangular opening measuring 180 cm in height and 50 cm in width is cut on the side of the tank as a doorway. The interior floor is drilled to install drainage elbows and pipes, ensuring smooth wastewater discharge. The toilet is bolted inside the tank, connected to the water tank and shower hose, and equipped with a faucet and stainless steel sink for basic usage needs.

4. Door and Detail Handling
   The door is made of wooden boards and hinges, with a door handle installed for easy opening and closing. Sealing strips can be added around the door frame to prevent odor diffusion. The tank surface can be sprayed with anti-rust paint to extend its service life.

Modified Structure Based on Water Storage Barrels

1. Mobile Base and Structural Reinforcement
   The water storage barrel is split vertically in the middle, with wooden boards laid at the bottom and universal wheels installed. Wooden strips are fixed horizontally on the upper side of the barrel to increase structural height and provide support for subsequent component installation.

2. Door Frame and Wall Construction
   A doorway is cut on the side of the barrel, with sponge strips installed to form the door frame. Plastic soft boards are embedded to create walls. The upper part retains the complete water storage barrel as the roof, with wooden strips painted with waterproof paint to enhance appearance and weather resistance.

3. Drainage and Sewage System
   A drainage pipe is installed at the bottom to form a floor drain, with a three-way connector attached to the side for installing the toilet and water tank separately. The drainage pipe extends to an external sewage barrel, while the inlet pipe of the sink is connected to the doorway via an extension pipe, enabling differential water utilization.

4. Functional Integration and Optimization
   The toilet adopts a water-saving design to reduce clean water consumption. The sewage barrel can be replaced periodically to lower cleaning frequency. The overall structure is lightweight, suitable for temporary venues or outdoor activities.

Core Components and Principles
Both structures use water storage containers as the core, achieving mobility through mobile bases and ensuring functional integrity with drainage systems and simple wall structures. Modular design facilitates disassembly, transportation, and reuse, making them suitable for emergency rescue, tourist attractions, and other scenarios.
