Drilling television flow velocity and flow direction measuring instrument capable of quickly positioning aquifer

The utility model provides a borehole television flow velocity and flow direction measuring instrument capable of quickly positioning an aquifer. The borehole television flow velocity and flow direction measuring instrument comprises a measuring probe and a computer, a simulated fisheye camera, an electrolysis electrode and an industrial camera are arranged in the measuring probe; the electrolysiselectrode is used for electrolyzing underground water to generate bubbles; the simulated fisheye camera is used for collecting image information in a drill hole and image information of bubbles and transmitting the image information to the computer. Displaying an image received by the computer to perform television imaging logging on the hole wall, and displaying a bubble movement track; the industrial camera is used for acquiring an image in the drill hole and transmitting image information to the computer when the movement track of the bubbles is not vertically upward; and the computer calculates the flow velocity
