Intelligent water meter

The invention relates to the technical field of water meters, in particular to an intelligent water meter which comprises a main body, an exchange mechanism is arranged in the main body, a gear is arranged on one side of the bottom end of the main body, and a slot is formed in the middle of the gear. The device has the beneficial effects that the filter screen is rotationally connected with the roller, when water flow enters the filtering mechanism from the water inlet, filtering is carried out with the help of the filter screen, meanwhile, a spiral piece in the device drives the filter screen to rotate clockwise under the impact of the water flow, and a brush in contact with the filter screen can brush the filter screen in real time; filtered water flow enters the main body from the drainage ports in the outer wall of the roller, the drainage ports in the outer wall of the roller face clockwise, the drained water drives the main body to rotate anticlockwise, insections on the outer side of the main body are
