Mobile Toilet Renovation Plan Diagram

Currently, a direct mobile toilet renovation plan diagram cannot be provided, but specific renovation steps and key points can be described based on existing creative plans.

I. Preparation of Basic Materials and Tools You need to prepare a large plastic bucket (with a recommended capacity of over 20L to ensure sufficient internal space), four universal wheels with brake functions, wooden boards (for making door frames and internal partitions), waterproof sealant, a drainage pipe (with a diameter of about 5cm), screws and screwdrivers, saws, electric drills, and other tools. When selecting materials, pay attention to waterproofing and durability. For example, the plastic bucket should be undamaged with uniform wall thickness, and the wooden boards should be treated for corrosion resistance.

II. Renovation of the Main Structure

1. Installing Universal Wheels at the Bottom: Drill holes at the four corners of the bottom of the plastic bucket using an electric drill, and fix the universal wheels with screws to ensure a firm installation and flexible wheel rotation. The brake function is crucial as it can prevent the toilet from moving during use.
2. Design of the Door Frame and Entrance: Cut wooden boards to create a door frame structure that matches the bucket opening. The recommended height is 1.2-1.5 meters, and the width should be convenient for entry and exit. The door frame should have reserved positions for hinge installation, and the connection with the bucket body should be sealed with waterproof glue to prevent odor leakage.
3. Making the Top Cover: Cut a circular wooden board with the same diameter as the bucket opening as the cover, and wrap rubber strips around the edges to enhance the seal. The cover can be designed to be openable for easy cleaning of the interior.

III. Optimization of Internal Functions

1. Installation of the Drainage System: Drill a hole in the center of the bottom inside the bucket, connect a drainage pipe, and extend it to an external container (such as another plastic bucket) for collecting excrement. The drainage pipe should be installed at an incline to use gravity for natural drainage and avoid blockages.
2. Internal Partitions and Toilet Seat: Install wooden board partitions inside the bucket to separate storage space (for items such as toilet paper and cleaning agents) and the usage area. The toilet seat can be made of plastic or wooden boards, and the edges should be smoothly treated to prevent scratches.
3. Ventilation and Deodorization: Drill small holes above the door frame or on the top cover, and install a small exhaust fan (optional) or a ventilation pipe to maintain air circulation. Activated carbon bags or camphor balls can be placed inside to assist in deodorization.

IV. Safety and Detail Handling

1. Edge Sanding: All cut edges of the wooden boards should be sanded smooth with sandpaper to avoid burrs that could cause injuries.
2. Waterproof Testing: After the renovation is completed, fill the bucket with water to test whether the drainage system leaks and whether the door frame is well-sealed.
3. Stability Check: When moving the toilet, ensure that the brake function of the universal wheels is normal to avoid the risk of tipping over.
