The potential energy of the water is converted into kinetic energy in the inlet nozzle or injector. Pelton turbines have the disadvantage that they require large height differences (hydraulic jumps) to convert hydraulic energy into electrical energy and do not have fluid flow control. A hydraulic turbine is a hydraulic turbomachine that uses the energy of a fluid passing through it to produce rotational motion, which is transmitted through a shaft, directly drives a machine or generator that converts mechanical energy into electricity, and thus it is a key element of hydroelectric installation.

The impeller comprises a central cylindrical wheel mounted on a shaft and a plurality of vanes extending radially from the center of the wheel. When the wind and hydraulic flow control turbine of the present invention is operating in hydraulic mode, it is depicted in the following drawings 1 ‘, 2’, 3, 4, 5 ‘, 6-9 and 10’ (this modification of the turbine in hydraulic mode contains elements shown in Fig. FIG. 2: is a top view of a vertically axial wind turbine with airflow control showing closed articulated guide vanes (1), hexagonal structure (7), hexagon radius (R) and mean curvature line (LCM) for the movable part (2) of the articulated guide vane. FIG. 4: is a top view of a vertically axial wind turbine with air flow control, showing an open moving part (2) of articulated guide vanes, a hexagonal structure (7) with vertices (13) of a hexagon, in which the vertical axes are parallel to the central axis of the hexagon ( 8), the circumference of the farthest dotted line (12) from the center corresponds to the connection of all the middle lines of curvature of the six moving parts (2) of the articulated guide vanes when they are closed; the locking system of the moving parts is shown by a dashed line, which can be formed on the basis of a hexagonal structure formed by an annular element (11) centered on the central axis of the hexagon (8), which contains the protrusions (14), which during rotation change the load on the angular strips ( 16), which exert a force on the protrusions (15), which are located at the base of six movable parts (2) of articulated guide vanes, ensuring the closure of the movable parts.

FIG. 1 is a top view of a vertically axial wind turbine with air flow control, which shows open articulated guide vanes (1), with a movable part (2) and a fixed part (3), zones corresponding to the upper (4) and lower ( 5) the surface (5) of the moving part, the rotor (b), the hexagonal structure (7), the radius (Rt) of the rotor, measured from the center of the hexagon (8), and the corresponding radius of the hexagon (R). Opposite blades of the pair are stationary, perpendicular to the direction of the wind, allowing them to withstand axial pressure and deflecting a given pair of blades, limiting the angle of deviation of these blades by means of a limiter. The publication of patent application GB 2485574 relates to a vertically axial water turbine mounted inside a vertical tower, which can be mounted on the bottom of the sea or river, the rotor has a direct action without a water flow concentrator, the rotor is a device with low efficiency, since its tangential component the velocity is equal to the flow velocity, in the central zone of the rotor there is turbulence with energy losses, a counterflow can be created in a significant part of the rotation of the rotor with oppositely directed flows and b locking the gripping inlet holes of the tower.
The resulting impulse rotates the impeller of the turbine, transferring energy to the axis of the turbine. The production process is based on kinetic energy converters similar to wind turbines, in this case using underwater installations. Hydroelectric installations equipped with a turbine of this type, most of the time, contain a long pipe, called a pressure channel, to move the fluid from high altitudes, sometimes more than two hundred meters.
The water pressure does not change when it passes through the turbine blades. In addition, it can be seen that the final portion of the fixed part (3) near the rotor changes its path and direction of curvature in order to increase the efficiency when the fluid enters tangentially to a circle of radius Rt formed by rotation of the rotor blades. U.S. Pat. rotations around the vertical axis clockwise between the first closed position and the second open position, the main differences between the subject of the present invention and the subject of US patent 6824349 I am that the latter is a direct-acting device without an air flow amplifier; it also includes moving parts in the rotor, which reduce speed and efficiency, it is a complex mechanism subject to erosion and wear with lubrication problems. The movable guide vane is designed to capture a larger moving mass of air than the rotor would capture without said blades, and the fixed guide vane concentrates and directs the fluid directly to the rotor blades faster than the speed of the external wind.
Savonius turbines with significantly larger sizes are used to generate electricity in deep-sea buoys, which require small amounts of electricity and require very little maintenance. The rotor operates on a drag force; a vertical-axis turbine with flow control in hydraulic mode has significant advantages over conventional vertical-axis turbines due to its resistance to operation. Dolor muscular pecho derecho . The lack of improvement associated with the efficiency or increase in the flow received by the propeller is essentially an inefficient and fragile rotor system, and it is impossible to control the depth of operation. Each articulated guide vane comprises a movable guide part and a fixed guide part, respectively forming a movable guide vane and a fixed guide vane. The inlet directs water to the rotor to rotate it. The blades have a curved shape, with no portion of the blade extending beneath the highest portion of the inlet when the other edge of the blade is aligned with the upper part of the inlet.
This drawing shows the mean curvature line (LCM) for the moving part (2). In this drawing, it can be seen that the end portion of the stationary part (3) near the rotor changes its curvature in order to increase efficiency when the fluid enters tangentially to a circle of radius Rt obtained by rotating the rotor blades. This turbine is the cheapest and easiest to use. The gradual opening of the blades for the full use of the corresponding energies is carried out automatically by means of tensioning devices, such as a tensioning device consisting of a winding drum and a cable, while its ends are attached to its blades and the drum attached to the impeller. Dolor muscular resaca . It contains a hollow rotor with six shark-shaped blades.

It contains an electric generator, unprotected from moisture, difficult to repair. The wind amplification unit contains at least one wind-reinforcing blade (21) and provides compressed air to the blades (12) of the wind engine. The system is difficult to mount and guide and is only suitable for unidirectional flows. The generator is located below the water level, creating problems of isolation and transmission, it only works with fluids moving at high speed, while the tangential component of the rotor speed is equal to the fluid flow rate.
The rotor blades are made in the form of shark fins. The blades are welded to the center of the wheel with end plates at each end of the impeller. FIG. 7 shows a perspective side view of an articulated guide vane with a hole in which an axis enters to provide rotation. As a rule, it consists of six groups of movable guide vanes, each connected to a fixed guide vanes, performing different functions in the dynamics of the fluid (air). It was developed by Gilkes in 1919 based on a modification of the Pelton turbine. Pelton turbines are adapted to use hydraulic jumps when the flow changes from a turbulent state to a calm one. The turbo impeller looks the same as the Pelton turbine impeller, divided in half. Savonius turbines are one of the simplest turbines.
An increase in the number of injectors increases the specific speed of the impeller by the square root of the number of jets (four jets give a doubling of the specific speed of the jet for a given turbine). Turbo Turbo is a pulse turbine. US patent 8210805 relates to a turbine containing an impeller mounted on a shaft. Savonius turbines are used when cost is more important than efficiency.
