The water wheel A2-11 is a mechanical structure in the prior art. A plurality of box-shaped grooves are circumferentially provided on the outer periphery of the water wheel A2-11. By introducing high-pressure water flow to impact the box-shaped grooves, rotational power is generated to drive the water wheel A2-11 to rotate around the axis. Generally, the water pipe A3 is connected to the water wheel driving device A2, especially at the middle position of the outer shell A2-1 of the water wheel driving device A2. The water pipe A3 is preferably connected to the box-shaped grooves of the water wheel A2-11 from the radial direction or the tangential direction of the outer periphery of the water wheel A2-11, which is beneficial to the water flow driving the water wheel A2-11 to rotate around the axis and reducing the turbulent water head loss of the water flow. The outer shell A2-1 is rotatably connected to the main shaft A2-10 through a shaft bracket A2-3. A shell end cover A2-13 is detachably connected to the first end of the outer shell A2-1.
