Water turbine with water pumping function

Abstract

The invention provides a water turbine with a water pumping function. The water turbine comprises a shell consisting of an upper end cover, a lower end cover and a side wall, wherein a rotatable water-wheel shaft is mounted between the upper end cover and the lower end cover; a rotor is mounted on the water-wheel shaft; a water inlet and a water outlet are formed in the shell; the rotor comprises ring grooves formed by adjacent coaxial cylinders; a water stop device used for closing the ring grooves is arranged on the shell; blade openings are formed in a blade cylinder between the adjacent ring grooves in the symmetric direction; rotatable blades are fixed to the blade openings through a blade shaft; a blade open-close guide rail is arranged on the upper end cover; and a blade control rod is arranged at the top of the blade shaft, is movably inserted into the blade open-close guide rail and drives the blade shaft to rotate when the rotor rotates. The water turbine with the water pumping function can utilize the water flow energy of rivers, streams and other running waters, as well as the water flow kinetic energy of ocean tides, and can also utilize water flow energy conversion in the natural state to achieve the water pumping purpose.

Description

technical field [0001] The invention relates to the field of water energy utilization, more specifically, to a water turbine with the function of pumping water. Background technique [0002] Modern water turbine technology often relies on the construction of dams to increase the potential energy of water so that water energy resources can be effectively utilized; however, the existing water turbine technology that does not require dams to convert water kinetic energy into mechanical energy has the bottleneck of low efficiency and high cost . The amount of water energy resources in rivers and oceans is extremely huge, but due to limited conditions, most places are not suitable for building dams, so that this part of water energy resources cannot be used under the premise of existing hydraulic turbine technology.

The amount of water energy resources in rivers and oceans is extremely huge, but due to limited conditions, most places are not suitable for building dams, so that this part of water energy resources cannot be used under the premise of existing hydraulic turbine technology. what we use

[0003] On the other hand, water pumps are important equipment for agricultural irrigation and breeding. Generally, they are mainly driven by electricity or gasoline or diesel engines. However, due to their high production costs and heavy dependence on modern industrial products, they are not easy to apply to remote places.

In order to overcome the above problems, there has been a water wheel pump using natural energy consisting of an axial flow turbine and a centrifugal water pump in the prior art, but it needs to build water wheel pumping stations on rivers and channels with a drop greater than 1 meter. There are restrictions such as high cost, low efficiency, and inability to move the dam
