[0002] When encountering a fire, if it is inconvenient for fire trucks to connect to water and the stored fire water is used up, water resources in nearby waters (such as rivers, lakes, rivers, seas, etc.) can be collected for firefighting. However, the firefighting treatment facilities for such waters are relatively simple. Generally, only grilles are set up to remove suspended matter. However, the components contained in the waters are more complex. When the pipeline is pumped out, the silt in the river water will also be pumped up, which can easily clog the fire pumping pipeline and affect the rescue efficiency. Utility Model Content
