Vertical water body mixing device for improving water quality of eutrophication water temperature stratification reservoir

A vertical water body mixing device for improving water quality of a eutrophication water temperature stratification reservoir comprises a main body pipe and two balance water tanks connected to the two ends of the outer side of the main body pipe respectively, wherein a balance weight steel ball capable of moving left and right is arranged in the middle space in the main body pipe; a left electromagnet and a right electromagnet which are used for attracting the counterweight steel ball to move left and right are symmetrically arranged at the two ends in the main body pipe respectively; and the left electromagnet and the right electromagnet are connected through a cable to a control circuit which can enable the left electromagnet and the right electromagnet to generate attraction to the counterweight steel ball at different time. The device has the advantages of being simple in structure, small in size, easy to transport, small in energy loss, large in action range, high in maneuverability, high in mixing eff
