Technical field

The invention relates to the field of pipeline desilting equipment, specifically a pipeline robot sewage suction and discharge head structure.

Background technique

In cities, various pipelines are spread all over the urban underground. Various industrial and domestic wastewater and rainwater flow into urban pipelines and are discharged through centralized sewer pipes. Various municipal sewer pipes, due to the long-term accumulation of soil, sand, gravel and various debris, most pipes will be silted, especially rainwater pipes, which cannot achieve the expected drainage effect and need to be cleaned regularly. For desilting urban pipelines, traditional manual methods and sewage suction trucks cannot enter the inside of the pipeline for desilting.

Existing robots are used to enter the inside of the pipeline to clean the siltation parts. However, the structure of the existing robots used for sewage suction and discharge heads is too simple and cannot automatically adjust the diameter of the pipeline. As a result, the cleaning effect is low and when encountering Even if the debris is more firmly attached, it cannot be scraped off, making it impossible to meet people's needs for cleaning the inside of the pipeline.
