Abstract

A water powered turbine has a rotor 6 which is mounted on a horizontal shaft and produces mechanical power when rotated by a source of pressurised water. The rotor is fitted with regularly spaced horizontal cups 5 around its periphery and is secured on the shaft within a prefabricated housing. Water is supplied directly onto the rotor cups via a square sectioned inlet duct 3 fitting precisely over the upper section of the rotor. A bank of blades 8 are fitted to the inlet duct on the trailing side of the rotor to create a partial vacuum within the cups prior to their re-entry into the inlet duct. <IMAGE>

Description

WATER POWERED TURBINE This invention relates to a Water Powered Turbine.
A water turbine is a well known method of obtaining mechanical power from a source of running water. It can consist of either a propeller or bladed rotar onto which a source of water is directed.
Existing turbines are relatively expensive owing to their design requiring a high degree of precision engineering.
According to the present invention this turbine consists of a prefabricated housing with a secured lid and open bottom for the exit of exhausted water.
Within the housing is contained a horizontal support shaft fitted with suitably sealed bearings.
Secured on the shaft is a metal rotar fitted with a series of regularly spaced peripheral cups.
A square sectioned water inlet duct fitting precisely over the upper section of the rotar is secured within the housing.
A bank of blades are fitted to the inlet duct, the width of and to the trailing side of the rotar, creating an outward airflow and cdnsequently giving a partial vacuum within the rotar cups, prior to their re-entering the inlet duct.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows the turbine housing with water inlet duct and centre shaft bearing.
Figure 2 shows the inlet duct in relation to the centre shaft which carries the rotar (not seen).
Figure 3 shows in section the inlet duct fitting precisely over the cupped rotar with vacuum blades in position.
Figure 4 shows three-dimensionally the peripheral cups in relation to the rotar.
Referring to the drawing the turbine comprises a prefabricated box housing 1 into which is secured a square sectioned water inlet duct 3 which fits precisely over the upper section of the rotar 6.
The rotar being fitted with peripheral cups 5 receives pressurised water from the inlet duct, rotates, discharging exhausted water from the rotar cups at point 7.
The turbine rotar is secured on a centre shaft 4 and runs in suitably sealed bearings 2 secured within the housing.
A bank of blades 8 covering the width of the rotar are fitted in such a way as to create an outward flow of air giving a partial vacuum within the cups prior to their re-entering the intake duct.

Claims (5)

1 A water powered turbine comprising of a prefabricated housing, carrying within a horizontal shaft on which is centrally mounted a turbine rotor incorporating horizontal peripheral cups. A square sectioned water inlet duct, secured within the housing, is fitted precisely over the upper section of the rotor. Secured to the lower side of the inlet duct, the width of and to the trailing side of the rotor, are a bank of vacuumising blades.
2 A water powered turbine as claimed in Claim 1 wherein is provided a turbine rotor which embodies horizontal peripheral cups.
3 A water powered turbine as claimed in Claim 1 or Claim 2 wherein is provided a square sectioned water inlet duct fitting precisely over the upper section of the rotor.
4 A water powered turbine as claimed in Claim 1 or Claim 3 wherein is provided a bank of vacuumising blades secured to the inlet duct on the trailing side and the width of the rotor.
5 A water turbine substantially as described herein with reference to Figures 1-4 of the accompanying drawings provided.
