Problems solved by technology

[0002] No matter the water turbine in the prior art is counterattack type, mixed flow type, impact type or propeller type, the flowing water acts on the blades of the water turbine and leaves in such a short moment, otherwise the water discharge will impact the blades of the water turbine The resistance will affect the power increase of the water turbine. On the other hand, the water still has a certain amount of energy due to the rapid departure, and the faster it leaves, the greater the loss of water energy.
The above are two technical problems that have not been well resolved in the current technology of water turbines, which directly affect the increase of power of water turbines and the improvement of water energy conversion efficiency

Abstract

The invention discloses a spiral hydraulic turbine comprising principal axis which is set vertically and has inner standing tank and outer standing tank fixed on with spiral water channel between them, carrick bitt on the lower part of the principal axis whose upper part is linked to dynamotor, water-collecting cavity is above the outer standing tank and there are several impulsing drop pit on the top of rotor of the spiral water channel; before water enters into the water channel, it firstly will pass through the impulsing drop pit for changing the kinetic energy of water into that of rotor, then it flows into the water channel, but the water gravity pushes the rotor to change the potential energy of water into the kinetic energy of rotor so that make the water turbine operate. The invention has simple structure and high water turbine utilization ratio.

Description

technical field [0001] The invention relates to a water turbine. Background technique [0002] No matter the water turbine in the prior art is counterattack type, mixed flow type, impact type or propeller type, the flowing water acts on the blades of the water turbine and leaves in such a short moment, otherwise the water discharge will impact the blades of the water turbine The resistance affects the power increase of the water turbine. On the other hand, the water still has a certain amount of energy due to running away, and the faster it leaves, the greater the loss of water energy. The above are two technical problems that have not yet been well resolved in the prior art water turbine, which directly affects the increase of the power of the water turbine and the improvement of the water energy conversion efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a screw turbine water turbine with simple str...
