Ryslavy hydraulic drive
(57) Abstract:Ryslavy the hydraulic actuator is designed to convert the energy of water flow. In the soil the soles of bed on a line lying across the direction of flow of water, installed on their Central axes of rotation of the at least two operating hydraulic motors, which are combined among themselves their form. The hydraulic motors are equipped with waterproof enclosures on opposite sides from where they align and center at the exit of the stretch of water between the hydraulic motors. Because of their linear arrangement, the hydraulic motors are made with opposite directions of rotation, and their blades are fitted with self-training to work when they are under the action of moving water. For a more complete use of the energy of moving water on the limits of the active and passive sections of the water in the enclosures of the hydraulic motors and the entrance of water into these fences, installed additional fencing in a palisade. 2 Il. The invention relates to hydropower installations using kinetic and potential energy moving along the bed of the river water.Famous modern hydroel is raised. However, modern plants use only the potential energy of falling from a height of dam water and only partially kinetic energy.All known hydropower plants with high or low dams are environmentally harmful facilities on large and small rivers.Known the simplest type hydraulic motor - water wheel containing the shaft, radial spokes and a wheel rim on which are mounted shaped blades . In these engines is only the potential energy of the raised dam water.Known water wheel used as the hydraulic drive containing the shaft, radial spokes, which are flat horizontal blades. The blades are immersed in the upper layer moving along the bed of the river water. Hydroelectric power with these engines could be environmentally friendly buildings. However, such motors use only some part of the kinetic energy of moving water.One of these hydraulic motors can be adopted as a prototype.The purpose of this invention is the use of kinetic and p is iginio on the riverbed.This goal is achieved by the fact that ryslavy hydraulic drive comprising a shaft, radial spokes of the wheel, the working blade, elements of reinforced concrete hydraulic structures, preventing the flow and alter the movement of water, and the fastening elements of hydraulic structures in the soil the soles of the river, according to the invention, at least two of the normally installed hydraulic motors combined in their forming an axis of rotation which is fixed vertically in the ground the sole of the river, and are located on a line lying across the direction of flow of water in the river, and the location of the hydraulic motors limited from the sides and at the exit from this area watertight enclosures installed with the possibility of forcing the movement of water from the riverbed in the area of finding campthotecin to the blades located between the combined hydraulic motors, which, in turn, is made with opposite directions of rotation around their axes, and preparing ourselves for the work of the blades is performed using the number along the radial spokes of a lever element, which is fixed on one side of the radial spokes to which is attached a direct effect on them grindcore to these spokes, but when the lever elements of the passive areas of water on the active sites on their border installed additional fencing in a palisade, can carry in axis and a lever elements of the blades.This construction of the hydraulic drive allows you to use both kinetic and potential energy moving along the rivers of water, because the water pressure is limited by fencing the area between the combined hydraulic forces resist equal to the work of water on the rotation of the blades of the hydraulic motor. These significantly significant braking force of the water, forward, free, create conditions for very large tumbler of water on this site, and this is due to the increase in potential energy of moving water.In Fig.1 shows a General view of the hydraulic drive in the plan, as well as the shape and arrangement of the waterproof enclosures, and Fig.2 - section a-a in Fig.1 of one of the hydraulic motors and the fence with the fence installed on the border of quiet and active areas of water in the location of the hydraulic motors and at the entrance to this place.Ryslavy hydraulic drive consists of not less than two hydraulic motors 1, partially closed in a water-proof fence 2.Cards riverbed, on which rests the whole moving part of the actuator. On the Central axis of the worn bearing sleeve 5 that carries the shaft 6 of the PTO and the hub 7 of the drum, on which is fixed a power radial spokes 8, carry a lever elements 9, which form in the work of the horizontal blades. Lever elements each fixed on its axis 10. Passive stretches of water separated by barriers in the form of a palisade 11.The hydraulic actuator operates as follows.After planting the hydraulic motor 1 at its Central axis 3, which is installed and fixed on a concrete pile 4, the blades of the hydraulic motor are immersed in the stream coming from the river water, which is limited waterproof enclosures 2, creating the possibility of formation between them some water, if the water creates some resistance to its movement in this area. The result is the immersion of the blades of the hydraulic drive in a moving stream of water, the blades at the initial immersion creates a certain deceleration of the moving water in this area, which causes the tumbler of water on the blades, causing them to rotate. When the rotation of the blades reaches a speed close to the speed of movement of the water, hydrodive, what causes an increase of the forward water from the riverbed due to backwater from the plot for a hydraulic actuator, which is not affected by inhibition.The tumbler of water on the plot of the blades increases the pressure of the water on the blades of the hydraulic motor, and implemented this additional increment of force on the blade in the form of potential energy accumulated in the tumbler of water.The hub 7 of a drum type must be designed so that when a temporary rise in water level in the river increased buoyancy force of the hub would allow all rotating part of the actuator to raise to the desired height.In addition to connecting the power stretch marks radial spokes 8, stretch marks can be provided and the axis of the lever 10 elements 9. In the drawings, it is not shown.The load is applied to the PTO shafts of the hydraulic motors can occur both separately and jointly, due to mechanical or electrical connection between them.All types of fencing can be done by pile driving of a certain size and shape in the bottom of the riverbed.The hydraulic actuators can be installed on fast flowing rivers, and moderate fullness of water, but relatively tangible heritage is On some rivers with moderate flow hydraulic drives can be installed on the bends of the rivers, artificial or natural, when the bulk of the water in the river flows with the highest velocity near the shore, which turned the river. Not less successful the selected location may be the place on the river where the greatest slope, or formed substantially narrow stretch of the river. All rivers stretched for a considerable distance, and convenient locations for installation of hydraulic proposed design will always be more than you need.The proposed hydraulic differs from all previously known hydraulic actuators. The main thing in it is an inexhaustible ability to use kinetic and potential energy of rivers, simplicity of design and installation.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.
