Water flow power machine

Abstract

The invention discloses a water flow power machine which comprises a rack, a first transmission shaft, a second transmission shaft, first chain wheels, second chain wheels, a caterpillar band and a plurality of blades, wherein the first transmission shaft and the second transmission shaft are rotationally supported on the rack respectively; two first chain wheels are installed on the first transmission shaft; two second chain wheels are installed on the second transmission shaft correspondingly; the caterpillar band is a ring-shaped caterpillar band which is composed of a plurality of unit caterpillar band boards; the caterpillar band is meshed with two first chain wheels and two second chain wheels; a plurality of roller wheels are connected with the inner side of the caterpillar band; a plurality of gantries are fixed at the outer side of the ring; a blade is hinged with each gantry; the water plane of the blade is provided with concaves and the back side is provided with convex cones; the blade is provided with baffles; the first transmission shaft and the second transmission shaft are provided with guide groove frames; when rolling below the central line of the first transmission shaft and the second transmission shaft, the roller wheel is in rolling match with the guide groove of the guide groove frame. The water flow power machine is high in utilization rate of water flow power, and is small in motion resistance.

Description

technical field [0001] The invention relates to a hydrodynamic machine. Background technique [0002] Water energy is a renewable and clean energy, and water flow energy has great potential. Existing hydrodynamic machines include two ends of impeller shafts and impellers thereof respectively erected on the left and right hulls or frames. During work, the impellers are rotated by the water flow, and the impeller shafts then drive generators or other work to operate. The hydrodynamic machine with this structure has the following disadvantages: the blades of the impeller affect each other in the impact direction of the water flow, that is, after the water flow positively impacts the previous blade, the water flow behind the blade becomes a turbulent flow. One blade can only be affected by turbulent flow, and the turbulent flow does little work on the latter blade. During the working process, only one blade is always positively affected by the water flow, and the other blades ...

AI Technical Summary

Problems solved by technology

The hydrodynamic machine with this structure has the following disadvantages: the blades of the impeller affect each other in the impact direction of the water flow, that is, after the water flow positively impacts the previous blade, the water flow behind the blade becomes a turbulent flow. One blade can only be affected by turbulent flow, and the turbulent flow does little work on the latter blade

During the working process, only one blade is always positively affected by the water flow, and the other blades are affected by the turbulent flow. In this way, the work effect of the water flow is greatly weakened, the loss of water flow energy is large, and the output power of the impeller is small; the other blades that do not work Susceptible to the influence of headwind, the impeller running resistance is large, which affects the efficiency of the hydrodynamic machine
