Abstract

The invention primarily aims at generating electrical energy from the flow power of pressurized water in water transmission lines. Water transmission projects should be analyzed and implemented according to geographical conditions, topography, resources and needs at different technical values. Therefore, the transmission lines do not have exactly the same characteristics. The same transmission line does not have the same technical characteristics at every point in itself. Pipe diameters, installation slope, flow rates and pressure values vary within the range of hydraulic accuracy. Depending on cost and technology, pipe qualities may also vary according to regions, countries and geographies. Water transmission lines are huge horizontal and vertical water columns whose flow is disciplined. To get maximum yield from any point of these columns, you need a special design for that point. The invention has the flexibility to be mounted at any point and designed individually for each point.

Description

HYDRAULIC TURBINE WITH BUILT IN ALTERNATOR

Field Of The Invention:

The present invention creates a new approach to hydraulic power generation or increases the efficiency of existing fields.

Background Of The invention:

The generation of electrical power from hydraulic power has been known and preferred for centuries. In the most basic way, the principle of operation is to take the power of water during the transition from one side of the turbine blade to the other side. The water hits the blades of the turbine, the shaft connected to the blades rotates, the electric generators connected to the shaft generate electricity using the speed and torque they receive from the shaft. As the power of water grows, the turbines grow, the electricity generators grow, the energy produced grows. With favorable geographical conditions, the facilities covers huge horizontal and vertical areas. Topography, estate, ecology, etc. landscape changes. Every work done, every cost is done only to produce energy.

Of the many alternatives for producing hydraulic power, it has always been the focus of interest to use the power of the pressurized water passing through the pipes. The same technique is used here. Turbine inside the pipe, a shaft extending from the outside of the pipe and electrical generators connected to the shaft. This technique, it has always been efficient and used as long as pressurized water comes from the pipe and flows into the pressureless environment. However, if the water comes from the pipe pressurized and continues pressurized, there is a problem of leakage in the pipe wall where the turbine shaft comes out. The higher the pressure, the more tightly the shaft should be wound for sealing. This prevents the shaft from rotating after a point due to friction. An exemplary there is a company that overcomes this problem and provides ideal conditions, and on their websites, it advertises that it can generate 100 KW of electricity from a 60-inch diameter water pipe and the turbine is patented. A similar another company is currently advertising on small diameter pipes. The reason for these examples is to express the importance of electricity generation from water transmission lines.

Purpose of the Invention:

The potential to generate electricity from the pressurized water passing through the transmission pipes and the effort to evaluate this potential as a common technique in the form of energy transmission from the shaft has been accepted as transfer to the whole world. However, this technique increases the power loss in the water due to excessive friction of the shaft at the pipe outlet and requires a pipe of maximum diameter to ensure optimum efficiency conditions. The energy loss caused by friction is compensated by the energy generator. As the material and sealing technologies progress, this production technique will improve.

The technique of Hydroterbine is completely different. Electricity is produced inside the tube and there is only an electrical panel outside the tube. A shaft does not come out of the tube because it does not have a shaft, so there is no loss of friction force for sealing. An external energy generator is not required because it is an energy generator and can be scaled up to ideal conditions and extended in length along the transmission line. There is a nozzle in the center of the turbine and this gives the tube internal or external nozzle form and does not cause loss of efficiency by reducing the turbine. By increasing the nozzle to ideal conditions, the turbine can also be enlarged Various alternatives can be designed according to the pressure, speed and flow values of the water flowing the blades from the transmission pipe and the speed and torque values can be adjusted. The energy to be taken from the dynamo in the nozzle is increased by the reverse rotation of the blade connected to the dynamo shaft and in this case the magnetic field effect created by the electromagnetic magnets effects increases. It has the potential for unlimited design diversity with too many variable parameters.

The installation of the hydroterbin is mounted to the existing transmission pipes by means of the tube connection flanges (3) located at the ends of the tube (2) which are suitable for the existing transmission pipes. The water flow from the transmission pipes loo is encounter with the helical encounter blades (8) at the end of the nozzle (12) to the nozzle beamings (14) in the nozzle bearing’s housing (13) located at the center of the nozzle fixing beams (15) connected to the tube (2). The water flow reaches the helical blades (9) on the nozzle (12) from the center to the wall. The water flow pushes the helical blades (9) and the turbine (29) starts to rotate on the axis of the nozzle 105 (12). Rotor helical copper winding groups(6), which are wound to the rotor helical core

(7) at the ends of the helical blades(9), also start to rotate. The diameter, form and length of the nozzle (12) and the form, angle and length of the helical blades (9) affect the variability of the speed and torque values of the turbine (29) and the hydraulic values of the transmission line. Therefore, the design of the turbine (29) is made in no accordance with the flow characteristics in the transmission line. The flow reduces the effect of cavitation by hitting the cavitation blades (10) connected to the rotor helical core (7) at the outlet from the helical blades (9). As the water flow leaves the turbine, it finally pushes the dynamo blades (27) and rotates the turbine (29) in the opposite direction. The dynamo blade (27) is connected to the dynamo shaft (21) supported by 115 the dynamo bearings (23) mounted to the dynamo bearing’s housing (22) located in the dynamo slot (16) in the nozzle (12). Since the dynamo blade (27) angles are reversed with respect to the helical blades (9) angles, the dynamo magnets (17) mounted on the walls of the dynamo slot (16) inside the nozzle (12) and the dynamo copper winding groups (19) which wrapped to dynamo rotor (18) connected to the 120 dynamo shaft (21) are rotated in the opposite direction, thus increasing the speed twice. In order to ensure that the dynamo slot (16) operates under anhydrous conditions, dynamo pressure seals (24) are arranged in the inlet and outlet of the dynamo shaft (21) into the dynamo shaft pressure lubrication channel (25). On the nozzle (12) is lubricated from dynamo shaft pressure lubrication channel cover (26) for 125 allow the dynamo shaft (21) to rotate easily in the dynamo shaft pressure lubrication channel (25) and to reduce the deformation of the dynamo pressure seals (24). In the dynamo housing (16), the electrical energy consisting of the magnetic field formed between the dynamo magnets (17) and the dynamo copper winding groups (19) is taken over the dynamo brush (20) and transmitted from the copper wire passage channels (11 ) to the rotor helical copper winding groups (6). In this way, the rotor helical core (7) becomes an electromagnet and electricity is generated from the alternator (28) formed by the stator helical copper winding groups (5) connected to the stator helical core (4) in the inner wall of the tube (2) by the effect of magnetic field. The stator helical core (4) diameter of the alternator (28), the number and dimensions of the stator helical copper winding group (5), the number and dimensions of the rotor helical copper winding group (6), the number and dimensions of the rotor helical core (7), as in the turbine (29) in accordance with the flow characteristics in the transmission line. At the same time, the turbine (29) and the alternator (28) must be made absolutely compatible with each other. The alternating electrical energy generated in the stator helical copper winding groups (5) can be taken from the electrical panel (1) on the tube (2) connected with the stator helical copper winding groups (5).
