Combination type equipment for cleaning water container

The utility model relates to a combination type device for cleaning water tanks, which mainly solves the existing defects that when the water tanks are cleaned, the operation can consume the labor and the time; the efficiency is poor, the secondary pollution is easy to be caused, etc. The periphery of the combination type device for cleaning water tanks is provided with a supporting rack; the center in the supporting rack is provided with a rotary cylinder body; the internal part of the cylinder body is connected with a water distribution pipe which is provided with a plurality of water outlet holes; the periphery of the cylinder body is provided with a plurality of duckbill-shaped water spray pipes which are provided with a plurality of end portions with diverse directions, and the lower bottom of the cylinder body is provided with an upper supporting base which is matched with a lower supporting base on a bracket. When a valve of a water inlet pipe is opened, the tap water can flood into the cylinder body; when the tap water reaches to a certain pressure, the tap water can be ejected from the internal part of the water spray pipes; when the combination type device for cleaning water tanks is subjected to the opposite force, the combination type device for cleaning water tanks can start to rotate in the direction of deviating from a nozzle, and the ejected water columns can make the water tanks cleaned.
