The utility model has the advantages of as follows:

1. the inclined hitting vertical type integral assembling machine set is arranged on a water inlet pipeline, a water inlet bent pipe and a 22.5-degree bent pipe are removed, the two parts are reduced, the head loss caused by the fact that the direction of water flow is changed when the water flow flows through the bent pipe is reduced, meanwhile, the material for manufacturing the bent pipe and the bolts for connecting the bent pipe are saved, and the length size of the machine set is also reduced.

2. The water turbine is vertically arranged, the axial direction of the rotating wheel is changed from the horizontal direction to the vertical direction, and the axial size of the rotating wheel is greatly smaller than the radial size, so that the service water head (the difference between the radial diameter and the axial thickness of the rotating wheel) of the water turbine is increased under the condition that the same size from the rotating wheel to the tail water surface is ensured.

3. The water turbine is arranged in a self-contained mode, the water turbine runner is directly connected to the generator shaft, and a water turbine main shaft, a water turbine bearing, a bearing seat and a coupler assembly for connecting the water turbine shaft and the generator shaft can be omitted. The use amount of materials is greatly saved, and meanwhile, the efficiency loss caused by the transmission of the coupler can be reduced due to the fact that the coupler is removed.

4. In the aspects of installation, arrangement and maintenance, because the unit is vertically arranged and the axis is upward, the standing area of the unit is reduced in the horizontal direction; in installation, only the generator shaft needs to be ensured to be vertical, and the workload of adjusting the axial coaxiality and the axial levelness of the four-pivot horizontal arrangement is reduced. In maintenance, the horizontal arrangement unit is easy to cause the condition that water flows seep out along the main shaft, and the vertical arrangement unit is provided with the rotating wheel completely in the machine base, so that the water seepage problem is completely avoided.
