Description

Technical Field

[0001] The invention relates to the field of septic tank detection, and in particular to a solar wireless manure and sewage liquid level sensor. Background Art

[0002] In recent years, large-scale toilet renovations have been carried out in rural areas, transforming traditional rural open-air toilets into three-chamber septic tanks with water flushing, which has greatly improved the rural living environment. The three-chamber septic tank is sealed and buried underground. Although the sanitary conditions have been greatly improved, it is not conducive to farmers to observe and grasp the use of space in the septic tank. Therefore, the septic tank is often full and overflowing, especially when the three internal compartments are blocked, it is more likely to overflow feces and sewage, causing the villagers' living environment to be polluted by feces and sewage. Since the cleaning of the buried three-chamber septic tank requires professional extraction equipment and a dedicated person, when the septic tank is about to overflow or blocked, it is best to notify the professional team in time to carry out orderly centralized cleaning and maintenance. Therefore, it is necessary to conduct non-manual real-time monitoring and information upload of the blockage and overflow of the three-chamber septic tank, so that professional cleaning agencies can timely grasp the current conditions of the many septic tanks scattered in the village, and make orderly arrangements for cleaning and maintenance work to improve maintenance efficiency. Up to now, septic tanks in rural toilet renovations still lack this technology. Summary of the invention
