Water and Electricity Installation for Color-Steel Mobile Toilets

The water and electricity installation of color-steel mobile toilets should be carried out in accordance with prefabricated characteristics, with standardized construction in water supply, drainage, and electrical circuits, and optimized design for high-altitude environments.

Water Supply Pipeline Installation

Water supply pipelines typically use PPR or PE pipes, which are corrosion-resistant and low-temperature resistant. There are two methods for pipeline embedding: one is to embed them in the interlayer of the box, utilizing structural space to reduce exposure; the other is to lay them along the structural frame for easy maintenance later. Anti-freezing insulation layers are crucial designs, especially in low-temperature areas, where rubber-plastic insulation cotton or polyurethane foam should be wrapped around the pipelines to prevent brittleness caused by low temperatures. The pipeline connections should use hot-melt or electro-fusion processes to ensure airtightness and prevent leakage.

Drainage System Design

The drainage plan should be selected based on the usage scenario:

• Gravity Flow Drainage: Suitable for areas with municipal sewage networks, the pipeline slope should be precisely calculated at 1%-2% to ensure the natural flow of waste.
• Pressure Drainage: In areas without municipal networks or with complex terrain, a mini vacuum pump should be installed to create negative pressure, enabling the directional transport of waste along dedicated pipelines to collection containers. Sealing is a core requirement, with pipeline connections using rubber seals or welding processes to prevent odor leakage; the negative pressure value should be precisely regulated by an intelligent controller (usually maintained at -30 to -50 kPa) to avoid pipeline blockage or pump overload. In high-altitude areas like Qinghai, some mobile toilets are equipped with self-circulating systems that use biodegradation technology to treat waste, reducing reliance on external sewage disposal.

Electrical Circuit Installation Specifications

Electrical circuit design should comply with waterproof and moisture-proof standards, with lines protected by PVC or metal pipes to avoid direct exposure to humid environments. All lines should be concentrated and connected to a pre-set power distribution module, which should have overload and leakage protection functions. Electrical equipment should be controlled by separate circuits:

• Lighting System: Use LED energy-saving lamps to reduce energy consumption;
• Exhaust System: Install axial fans to ensure ventilation efficiency;
• Socket Circuit: Set up independently to prevent high-power equipment (such as electric heaters) from affecting other circuits.

High-Altitude Environment Optimization

To address the issue of unstable power supply in high-altitude areas, most solutions integrate photovoltaic power generation systems:

• Photovoltaic Panels: Installed through customized brackets that fit the roof's curved surface, with the tilt angle adjusted according to local latitude (usually 30°-45°) to maximize light collection efficiency; the brackets are made of aluminum alloy to reduce wind resistance while ensuring strength.
• Energy Storage Devices: Select low-temperature lithium battery packs that can operate normally at -20°C; equipped with intelligent charge-discharge controllers that automatically adjust power supply strategies based on usage frequency (such as daily usage duration), prioritizing basic functions like lighting and exhaust.

Through the above designs, the water and electricity systems of color-steel mobile toilets can meet basic functional requirements while adapting to complex environmental conditions, ensuring long-term stable operation.
