Description

Technical Field

[0001] The utility model relates to the technical field of mobile toilets, in particular to a drainage device for mobile toilets. Background Technique

[0002] A mobile toilet is a temporary sanitary facility that is convenient for installation and use, and is widely used in various public places, temporary activities, construction sites, disaster relief and other environments. With the acceleration of the urbanization process and the increase in large-scale activities, the demand for mobile toilets is growing day by day. In order to meet the sanitary requirements in different environments and conditions, mobile toilet technology is constantly developing and innovating.

[0003] According to the survey data, some surveys on the usage of public toilets show that the proportion of urination generally accounts for more than 80% of the total usage. For example, in the mobile toilets of some large-scale activities or music festivals, the proportion of urination usually accounts for more than 90%, while the proportion of defecation is relatively small. However, the existing drainage structure of mobile toilets still has problems such as being unable to expand the sewage storage space, unable to discharge a large amount of urine, and inconvenient to extract the sewage in the storage tank.

[0004] Therefore, it is very necessary to invent a drainage device for mobile toilets. Content of the Utility Model

[0029] Working principle

[0030] 1. Collection of wastewater and sewage:

[0031] When the user uses the squat toilet 4, the wastewater and sewage will be discharged into the first sewage storage tank 31 of the toilet gray water tank 3 through the squat toilet.

[0032] 2. Preliminary storage:

[0033] The first sewage storage tank 31 is installed inside the mobile toilet base 1 to initially collect and store the wastewater and sewage. The first sewage storage tank is designed as a square plastic container with a large storage space.

[0034] 3. Transfer of wastewater:

[0035] At the halfway height of the first sewage storage tank 31, there is a discharge port which is connected to a communicating pipe 32. The communicating pipe is fixed on one side of the first sewage storage tank and controls the flow of wastewater through a solenoid valve 33.

[0036] The solenoid valve 33 is an electrically controlled valve and is opened once every 30 minutes for 3 minutes. When the solenoid valve is opened, the wastewater flows from the first sewage storage tank to the second sewage storage tank 34.

[0037] 4. Further storage of wastewater:

[0038] The second sewage storage tank 34 is installed at the other end of the communicating pipe 32 and is located outside the mobile toilet. The second sewage storage tank is also a square plastic container and is used to receive and store the wastewater flowing out from the first sewage storage tank.

[0039] 5. Extraction and cleaning of wastewater and sewage:

[0040] A sewage extraction port 35 is opened on the surface of the first sewage storage tank 31 and is directly below the sewage extraction window 5. When it is necessary to clean the wastewater and sewage, it can be conveniently extracted from the sewage extraction port through the sewage extraction window.

[0041] The sewage extraction window 5 is a rectangular opening on the toilet floor 2 and is covered by a metal plate to ensure sealing during normal times and convenient use.

[0042] 6. Auxiliary functions of the toilet floor and steps:

[0043] The toilet floor 2 is made of a stainless steel metal plate and is fixed above the mobile toilet base 1. Through the raised design, more space is provided for the installation of the toilet gray water tank 3, and the structural stability and durability are ensured.

[0044] The toilet steps 6 are fixedly installed on the front side of the toilet floor to provide a passage for users to enter and exit.
