Description: HYDRAULIC TURBINE ASSEMBLY DESCRIPTION OF THE PRIOR ART The use of hydraulic turbines is known in the prior art. More specifically, hydraulic turbines heretofore devised and utilised are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfilment of countless objectives and requirements. Known prior art hydraulic turbines include U.S. Patent 4,437,017; U.S. Patent 4,963,780; U.S. Patent 4,219,303: U.S. Patent 4,816,697; U.S. Patent 4,443,707 and U.S. Patent 4,284,899. While these devices fulfil their respective, particular objectives and requirements, the aforementioned patents do not disclose a new hydraulic turbine assembly. The inventive device includes a water inlet pipe (which is preferably vertical) being extended into the water reservoir of a dam to deliver water to the conventional hydroelectric generation system. The water inlet pipe has a water inlet point being positioned in the water reservoir to create a free vortex formation. An outer housing tube having an inlet cone for collecting water from said inlet free vortex formation and an outlet draft in fluid communication with the water inlet pipe is provided to permit water to pass through the outer housing tube to the water inlet pipe. A rotor and turbine assembly having a rotor unit and at least one generator unit for creating electrical energy is disposed within the outer housing tube to permit rotation of the rotor unit within the outer housing unit by water passing through the outer housing tube. Each of the generator units is operationally coupled to the rotor unit so that the rotational energy of the rotor unit is transferred by the generator units into electrical energy. In these respects, the hydraulic turbine assembly according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of deriving extra energy out of a conventional hydroelectric power generating system. SUMMARY OF INVENTION In view of the foregoing disadvantages inherent in the known types of hydraulic turbines now present in the prior art, the present invention provides a new hydraulic turbine assembly construction wherein the same can be utilised for deriving extra energy out of a conventional hydroelectric power generating system. The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new hydraulic turbine assembly apparatus and method which has many of the advantages of the hydraulic turbines mentioned heretofore and many novel features that result in a new hydraulic turbine assembly which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art hydraulic turbines, either alone or in any combination thereof. To attain this, the present invention generally comprises a water inlet pipe (which is preferably vertical) being extended into the water reservoir of a dam to deliver water to the conventional hydroelectric generating system. The water inlet pipe has a water inlet point being positioned in the water reservoir to create a free vortex formation. An outer housing tube having an inlet cone for collecting water from said inlet free vortex formation and an outlet draft in fluid communication with the water inlet pipe is provided to permit water to pass through the outer housing tube to the water inlet pipe. A rotor and turbine assembly having a rotor unit and at least one generator unit for creating electrical energy is disposed within the outer housing tube to permit rotation of the rotor unit within the outer housing unit by water passing through the outer housing tube. Each of the generator units is operationally coupled to the rotor unit so that the rotational energy of the rotor unit is transferred by the generator units into electrical energy. There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilised as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention. Further, the purpose of the abstract at the end of the specification is to enable the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way. It is therefore an object of the present invention to provide a new hydraulic turbine assembly apparatus and method which has many of the advantages of the hydraulic turbines mentioned heretofore and many novel features that result in a new hydraulic turbine assembly which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art hydraulic turbines, either alone or in any combination thereof. It is another object of the present invention to provide a new hydraulic turbine assembly which may be easily and efficiently manufactured and marketed. It is a further object of the present invention to provide a new hydraulic turbine assembly which is of a durable and reliable construction . An even further object of the present invention is to provide a new hydraulic turbine assembly which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such hydraulic turbine assembly economically available to the buying public. Still yet another object of the present invention is to provide a new hydraulic turbine assembly which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith. Still another object of the present invention is to provide a new hydraulic turbine assembly for deriving extra energy out of a conventional hydroelectric power generating system. Still a further object of the present invention is to allow, if required, water to be returned to the reservoir, utilising the extra energy created, and thereby provide an alternative means of increasing the overall energy output of a conventional hydroelectric power generating system, by increasing the volume of water available to pass through that system . Still yet a further object of the present invention is to allow, if required, any number of hydraulic turbine assemblies to be incorporated into the reservoir at various locations within the reservoir, their respective outlet pipes each ultimately joining with the main outlet pipe of the reservoir which leads to the conventional hydroelectric power generating system, thus multiplying the additional energy output of the hydraulic turbine assemblies within that system. Yet another object of the present invention is to provide a new hydraulic turbine assembly which includes a water inlet pipe (which is preferably vertical) being extended into the water reservoir of a dam to deliver water to the conventional hydroelectric generating system. The water inlet pipe has a water inlet point being positioned in the water reservoir to create a free vortex formation. An outer housing tube having an inlet cone for collecting water from said inlet free vortex formation and an outlet draft in fluid communication with the water inlet pipe is provided to permit water to pass through the outer housing tube to the water inlet pipe. A rotor and turbine assembly having a rotor unit and at least one generator unit for creating electrical energy is disposed within the outer housing tube to permit rotation of the rotor unit within the outer housing unit by water passing through the outer housing tube. Each of the generator units is operationally coupled to the rotor unit so that the rotational energy of the rotor unit is transferred by the generator units into electrical energy. Still yet another object of the present invention is to provide a new hydraulic turbine assembly that derives extra energy out of a conventional hydroelectric power generating system by incorporating a second turbine generator at the inlet from the reservoir while allowing the majority of the energy to be available to the conventional turbine arrangement of the dam. Even still another object of the present invention is to provide a new hydraulic turbine assembly that has an inlet designed to allow a free vortex to form, the energy of which is currently lost in the form of other turbulence. The source of this energy is a combination of various parameters including initial pre-swirl in the water, the Coriolis effect from the rotation of the Earth and the shape of the reservoir. These together with other objects of the invention, along with the various features of novelty which characterise the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference now to the drawings, and in particular to Figures 1 through 9 thereof, a new hydraulic turbine assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral 3 will be described. More specifically, it will be noted that the hydraulic turbine assembly 3 comprises a vertical water inlet pipe (1), an outlet draft tube (8), and a rotor and turbine assembly (3) . As best illustrated in Figures 1 through 9, it can be shown that this hydraulic turbine assembly (3) is designed to derive extra energy out of a conventional hydroelectric power generation system by incorporating a second turbine generator at the vertical inlet from the reservoir. The invention as shown in Figure 1 consists of a modular designed removable electrical generation turbine unit attached to a vertically facing inlet water feed pipe that supplies water to the conventional down stream or lower electrical generation power plant. As shown in Figure 1, the vertical inlet pipe (1) presents itself with a flange receiving end (42) suitable for the attachment of a flange mount (30) of the hydraulic turbine unit (3) and may be fabricated from concrete, steel or other suitable materials in order to withstand the weight and torsional loading subjected by the unit. The horizontal positioning of the vertical inlet pipe (1) within the water reservoir (41) should allow for adequate clearance from retaining or dam wall (31) , base (32), water surface (33) and sides of the water reservoir (41) so as to enable the proper formation of a free inlet vortex (34) specific to the application. The water supply or flow can be slowed or stopped using a suitable form of valve or shut off gate (2) necessary for system shut down. The flange mount (30) of the hydraulic turbine assembly (3) itself is flange mounted to the flange receiving end (42) of the water inlet pipe (1) and so can be easily disassembled and removed for repairs, maintenance or to enable the conventional hydroelectric generating system (35) to operate as previously. A power output cable (4) is appropriately insulated and exits from a hermetically sealed generator unit (29) to the required supply feed point outside the water reservoir (41) . The height of the water inlet point (5) of the unit from the free surface of the water (33) is such as to allow for the formation of the free vortex (34) above the hydraulic turbine assembly (3) and depends on the particular application. A screened enclosure structure such as a mesh screen (6) may be required depending on the application for the prevention of material other than water from entering the system. As depicted in Figure 2, the hydraulic turbine assembly (3) comprises three sections the first of which is described as the inlet cone (7). Its function is to collect the inlet water and is shaped to minimise inlet hydraulic pressure losses according to the particular application as well as to locally increase water velocity entering a turbine main section (10). The inlet cone (7) can be made from concrete or steel or other suitable materials according to the specific application and must withstand the high water velocities in its proximity and also the weight of the whole of the unit for unit installation and disassembly. The inlet cone (7) is flange mounted at a flanged joint (36) to the main section (10) and can be disassembled from it. The third section of the hydraulic turbine assembly shown in Figure 2 is an outlet draft tube (8) which diverges in shape and is shaped generally so as to reduce turbine exit water velocity and to further increase the energy potential across the turbine. Its construction is similar to that of the inlet cone (7). The outlet draft tube (8) is also flange mounted to the main section (10) at a flanged joint (43) and can also be disassembled from it. The power outlet cable (4) exits the hydraulic turbine assembly (3) via one turbine support pillar (9) and may either pass through a hollow support pillar (9) from the hydraulic turbine assembly (3) or be attached along it. The exit point may also be a hermetically sealed junction box (37) where disconnection is possible separating the cable (4) from the rest of the unit. The hydraulic turbine assembly (3) main section (10) completes the three part structure of the hydraulic turbine assembly (3) and is the working section containing the turbine rotor and electrical power generating equipment. Its outer housing tube (13) is made from similar materials to the inlet cone (7) and outlet draft (8) and mounts to each respectively at its inlet and outlet flanged joints (36, 43) mount to each respectively. Continuing the modularity of the concept when separated from the inlet cone (7) and outlet draft (8), the main section (10) as shown in Figure 3 can be further disassembled to reveal a top cap assembly (11) flange mounted between the main section (10) and inlet cone (7) containing the top support pillars (9) that help suspend the rotor and turbine assembly (38) in the middle of the water stream as well as the streamlined top cap (11) . The purpose of the top cap assembly (11) is to minimise the hydraulic form losses of the rotor and turbine assembly (38) and does not rotate with the rotor unit (26) . The support pillars (9) are also hydrodynamically designed to minimise form drag and also do not rotate. Similarly, the lower cap assembly ( 12) is a structure that does not rotate but serves to support the rotor and turbine assembly (38) whilst minimising drag. A flanged outer housing tube (13) completes the support structure for the rotor and turbine assembly (38) as well as of course containing the water. As shown in Figure 4, the rotor and turbine assembly (38) is supported by an upper support plate (14) and a lower support plate (15) which do not rotate but serve to attach the contained unit to the top cap assembly (11) and bottom cap assembly (12) mentioned above. The support plates (14, 15) also fix a support shaft (16) which also does not rotate thereby minimising the actual number of components and hence weight of the parts that do rotate in the unit and mentioned later on. The actual method of fixing can be splining or keying or other suitable method to prevent the shaft (16) from rotating with respect to the fixed support plates (14, 15) . The fixed support shaft (16) also carries an upper bearing assembly (17) and a lower bearing assembly (18) about which the revolves the rotor (26) . The rotor unit assembly (26) may need to be sealed against water entry and for this, felt or any suitable seals may be used for an upper seal (19) and a lower seal (20) Upper retaining cap (21) and lower retaining cap (22) also serve to complete the sealing and to vertically locate the fixed support shaft (16) . The rotor and generator sub-assembly (23) can be seen separated here from the upper and lower bearing assemblies (17, 18) and upper and lower support plates (14, 15) . An upper bearing plate (24) and a lower bearing plate (25) are attached and rotate with the rotor (26) . Their function is to support the rotor (26) in the first instance but also, in the case of the upper bearing plate (24), to transfer the rotational energy of the rotor (26) to the electrical generator unit (29) via a series of gears. The upper bearing plate (24) is itself an annular gear with internal teeth that act on a gear box (27). As depicted in Figures 6 and 7, the rotor unit (26) is the main rotating element of the turbine containing three to six blades (40) depending on the application. These blades (40) are pitched at a greater angle at the tip and shallower at the hub to accommodate for differences in relative speeds between the blades (40) and the water for varying distance from the central axis of the rotor unit (26). A gear box assembly (27) accepts the rotational energy from the upper bearing plate (24) and transforms the torque and speed to suitable values depending on the application feeding it to the generator units (29) . The number of sets of gears (39) used depends on the number of modular generator units (29) deployed in the application. A gear carrier (28) that does not rotate and is fixed by keying or other suitable method to the central fixed support shaft (16) is used to maintain the gear box gears (39) in their relative positions and prevent them from revolving around with the upper bearing plate (24) . The shape of the gear carrier (28) depends on the number of modular generator units (29) deployed in the application. The mechanical rotational energy is finally converted to electrical energy by the use of generator units (29) that are firmly attached to flat sections of the fixed support shaft (16) and do not themselves move. The number of generator units (29) deployed depends on the particular application, the annular space considerations and the available torque generated. Each generator unit (29) is fully sealed and submersible, the output cable (4) being also fully sealed. In use, the inlet of the hydraulic turbine assembly (3) is designed to allow a free vortex to form, the energy of which is currently lost in the form of other turbulence. The source of this energy is a combination of various parameters including initial pre-swirl in the water, the Coriolis effect from the rotation of the Earth and the shape of the water reservoir (41) . The low operating head, large flow rate and significant water swirl thus lends itself to the use of an axial flow type of hydraulic turbine as in the present hydraulic turbine assembly (3) . In use, it should also be understood that this hydraulic turbine assembly (3) may be used separately from the conventional hydroelectric generating system (35) of the dam (31) as a stand alone hydroelectric generating system. That is, the hydraulic turbine assembly (3) may be used so that water passing from the hydraulic turbine assembly (3) does not have to enter the conventional hydroelectric generation system (35) of the dam or it may be used in a system that does not include the conventional hydroelectric generating system (35) . Because of the low operating hydraulic head across this hydraulic turbine assembly (3), the majority of the energy to the conventional turbine arrangement for the dam would still be available. Thus, the total energy output of the system with the added hydraulic turbine assembly (3) would then be greater than that using only the conventional turbine arrangement . One of the greatest strengths of the hydraulic turbine assembly (3) is that by drawing upon the Coriolis effect this invention does not thereby interfere with the operation of the conventional hydraulic turbine system of the dam (31) . Accordingly, this invention does not contravene the conservation of energy principle. As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. With respect to the above description then, it is to be realised that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
