Water moment test device for Kaplan turbine model

The utility model discloses a water moment test device for a Kaplan turbine model and relates to the manufacturing field of water turbine power generation equipment. The water moment test device comprises a blade and a runner body; a blade shaft of the blade is installed on the runner body through a ball bearing and extends to the inside of the runner body; and a torque sensor is arranged on the blade shaft and is connected with a wireless data transmission terminal. The water moment borne by the blade is measured by the torque sensor on the blade shaft. The water moment test device has the beneficial effects that as the water moment test device for the Kaplan turbine model is optimal in structure configuration and simultaneously adopts advanced wireless transmission design, the water turbine model can more accurately measure the water moment and better carries out data signal transmission and processing; and moreover, as a discharge cone of the water turbine test device is made of nonmetal materials, the wireless signal transmission is facilitated.
