The water pipe base 100 is arranged on the shore, and the other end of the water outlet pipe 220 of the three-way joint 200 is rotatably inserted into the water pipe inlet 110 on the supporting surface 100a, so that the rocker arm type water taking connecting pipe 600 obtains the rotational freedom degree in the horizontal plane. When the water surface where the floating pontoon is located rises and falls and jolts due to the change of external conditions, the rocker arm type water taking connection pipe can swing adaptively relative to the water conveying pipe base on the shore through a movable structure formed by combining the Y-shaped three-way pipe and the T-shaped three-way pipe.
