MICRO-HYDRO TUBE WELI/ BORE WELL
TURBINE
FIELD OF THE INVENTION
The present invention relates generally to micro hydro turbines and, more particularly, to Micro hydro turbines for use in Tube well or Bore well i.e. micro-scale applications. The present invention also relates to a method of using micro hydro turbines in Tube well or Bore well i.e. micro-scale applications for generation of electric current as well as for running mechanical equipment's.
BACKGROUND OF INVENTION
Electrical generation from environmentally friendly sources or alternative energy sources like water has long been a goal of many, for both economic as well environmental concerns. Turbines are used for the same purpose. Turbines convert water's energy into electrical energy. This has been achieved by exposing a rotor to flow of water. The rotor turns a generator typically mounted to it, driving the generator to create electricity. The rotor and generator combination (turbine generator) is mounted at water flow.
Turbine generators have been particularly successful in utility-scale applications. In such applications, large size turbines and generators are used and are located near big dams and waterfalls etc. These generators are further connected to grid for power storage and effective distribution. These utility-scale installations are very costly and generate
electricity for requirements of a town, state etc. Sizes of investment, availability of water resource, locations are factors that must be properly align to make such an investment worthwhile. Therefore considering power generation these utility-scale installations play a big and important role but the same could not be said to be exclusive role having regard to forgoing, as an alternative source of electricity. Thus, current approaches are typically limited to utility scale or at the maximum to small-scale applications and are impractical in taking full advantage of available resources.
Therefore generating electricity using alternative energy source in micro-scale applications has been dream for many since long. But using the turbine system at such a micro level that can simultaneously satisfy power requirement of a household has inherent drawback of efficiency or lack of sufficient revolutions to actually generate the electricity.
It should, therefore, be appreciated that there exists a need for a turbine system for use in micro-scale applications in a broad range of settings, including industrial settings that is cost-effective, environmentally safe, small, compact, easy to handle and carry and does not hamper other systems. The present invention fulfills this need and others. The micro hydro Tube well / Bore well turbine can effectively be used to generate electricity in farm lands depending upon the tube well or bore well used for irrigation also at places having a natural water fall at very low expenses. The micro hydro bore well / tube well turbine can also be used for running mechanical equipments. Further water flowing out of the blades of the turbine still serves its purpose.
RELATED INFORMATION
It is generally known in relation to hydroelectric power generation that water flowing through a pipe delivers its energy to the turbine. The efficiency of system apart from the turbine and its components depends upon the flow, amount of water and fall height.
After the water has delivered a part of its energy to the turbine, the water further flows away into water channel.
The turbine is usually coupled to an AC generator, with which the kinetic/ potential energy of the water generated by the runner is converted into electrical energy, which is then supplied to power grid for storage and distribution.
SUMMARY OF THE INVENTION
It is therefore principal object of the invention to provide an means, by which the energy
of water coming through a Tube well/ bore well or any small water reservoir can be
effectively used to generate electricity for direct use.
Another object for the invention is to use available energy of water to produce electric
energy that can be stored in a battery for later use.
A further object of the invention is to use available energy of the water for running the
mechanical equipment's directly.
Accordingly the invention provides a micro hydro Tube well/ Bore well turbine that is so equipped that it could use the linear kinetic as well potential energy of the water coming out of bore well or tube well to produce the electric energy. The turbine comprises of a nozzle that thrust the water perpendicularly on the blades of the runner to make them rotate. The turbine further comprises of a pulley attached to the runner, which through a belt could be connected to the DC Dynamo, AC Generator or mechanical equipment as per need.
The invention may be used to provide electricity to the household, to run mechanical equipment, to run a submersible water pump etc.
Advantage of the present invention is that micro hydro Tube well/ Bore well turbine can be used directly in a farm land by attaching the inlet pipe of the turbine to the water flow of ihe bore well/ tube well or to a small water reservoir.
The kinetic energy generated in the runner of the turbine can be used for charging battery by attaching a DC Dynamo to the pulley of the turbine.
Further the kinetic energy generated in the runner of the turbine can be used directly for household use by attaching an Ac Generator to the pulley of the turbine.
Further the kinetic energy generated in the runner of the turbine can be used directly for running mechanical equipment's by attaching mechanical equipment to the pulley of the turbine through a belt.

BRIEF DESCRIPTION OF THE DRAWINGS
FIGURE 1 is cross sectional view of micro hydro Tube well / Bore well turbine. DETAILED DESCRIPTION
As illustrated in the FIGURE the cross flow drum-shaped turbine B, comprises an inlet pipe F, an elongated, rectangular-section nozzle A directed against curved blades C totaling 18 and having width of 30 mm and length 140 mm, mounted on a cylindrically shaped runner D having diameter of 150 mm.
The cross-flow turbine B allows the water to flow through the blades C twice. The first pass is when the water flows from the outside of the blades C to the inside; the second pass is from the inside back out. A guide blade at the entrance to the turbine B directs the flow to a limited portion of the runner D with lower heads. The nozzle A reduces the cross section area of water increasing the thrust with which water hits the blades C of the turbine B, thereby passing their linear kinetic/ potential energy to the turbine B resulting in rotating the blades C of the runner D which in turn starts rotating the Pulley E, which through the belt could drive a DC Dynamo / AC Generator/ Mechanical Equipment (not shown in the figure).
When the desired r.p.m. is in the range of 750-1000, the system achieves the maximum efficiency.
The pulley through the belt can be attached to a DC Dynamo for producing DC current storable in Battery for late use.
The pulley through the belt can also be attached to an AC Generator for supplying electric current directly to household.
The pulley through the belt can alternatively be attached to mechanical machine directly.
In this fashion the water coming through a Tube well / Bore well can effectively be used for generating electrical for households or running mechanical equipment's directly. The measure set forth in accordance with one aspect of the invention is extremely simple and nonetheless at the same time highly effective.
