Abstract

The hopper water turbine is a new type of water turbine showing high performance for electric power production. It is extremely simple to be built and operated, with extremely low cost construction and installation cost, almost zero maintenance needs and negligible civil works. Basically, it is a cylinder which rotates by the friction torque of the flowing water and does not demand special blades except auxiliary ones to prevent vibrations or for torque strengthening in special conditions. This enables the water turbine to be handy and efficient even for house scale utilization. The hopper water turbine is composed by an annular stator (1) which injects the water in the interior of the hopper rotor (2) in the direction of the Coriolis phenomenon; the water swirls and drifts the hopper rotor in a rotating motion. The water outflows through the central evacuation hole (3) at the bottom and returns to the riverbed, allowing the fishes to run down the river. Additionally, the hopper water turbine is beneficial to the quality of water enriching it with oxygen.

Claims

AMENDED CLAIMS received by the International Bureau on 14 December 2015 (14.12.2015)
1. A hopper water turbine which is consisted of a metallic frame (1.3), an annular stator (1 ) and a hopper totor (2) placed in axial pattern, the annular staler: (1) is fixed on. the metallic frame (1.3) and- has at least one pair of injection holes (1,2) fixed in the interior of the hopper rotor (2), the hopper rotor (2) is open at the top end in order to fit in the annular stator (I), at the bottom (2.2) it has a central outflow hole (3) sad it is shaped downwards in a second level on which it is fixed firmly a central rotation axis (2.1) and has a pair of outflow holes (2,4) furthermore the central rotation axis (2.1) is joined to the hopper rotor (2) with a pair of anti-vibration blades (2.3), the centra! rotation axis (2.1) is supported by the metallic frame (1.3) through two suspension bearings (1.4) at the ends, and is characterized by the injection holes (1.2) thai inject water on the internal wall of the hoper rotor (2) creating a smooth natural vortex and through the friction on the wall transfer rotation to the hoper rotor (2), the annular stator (1) gives the water initial inertia to the Coriolis direction permitting at the same time tangential angles to the injections holes (1.2) in relation to the interior wall of the hopper rotor (2), the open top of the hopper rotor (2) slaps to the center forming a conical frustum in order to contain the boundary level of the smooth vortex inside the hopper rotor (2), the pair of anti - vibration blades (2,3) is placed to the top of hopper rotor (2) down from the impinging line of the injected water having hydfodynarmc profile in order to minimize resistance to the water arid to avoid disturbed vortex, the central hole (3), at the bottom (2.2), is shaped downwards to a second level and has a pair of outflow holes (2.4) in order to permit final discharge of the water at the center of the hoper rotor (2) like natural smooth water vortices.
2, According to claim 1 , the hopper water turbine is characterized by the annular stator (1) that gives the water initial inertia to the Coriolis direction depending on the latitude of the water turbine installation.
3. According to claims 1 and 2, the hopper water turbine is characterized by the anti - vibration blades (23) having hydrodynamic profile oriented against the direction of the Coriolis rotation.
4. In the "Document D1", the liquid is injected to the interior via infusion tubes, while in case there is an annual stator, which gives the advantage of putting the liquid into the original circular motion in the direction of the Coriolis phenomenon. It also has the advantage of giving slopes and tangential angles of attack into the inner wall of rotor so as the frirtion forces should apply tangentially, exerting more power and less vibration to the rotation system.
5, Some parts which are similar in both "Document Dl" and my own, have the following differences: the radial arms end up at the lugs, where impinges the liquid and reacts with them, while the anti-vibration blades of my apparatus have hydrodynamic form in order to minimize their reaction and to avoid the creation of turbulent vortex, ensuring in this way a smooth natural vortex.
