Description

Hydraulic seesaw to generate electricity.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a rocker hydraulic to generate electricity, which has been devised with the purpose of harnessing the energy that streams have in that in small distances there are slopes of the order of 2 to 10 meters The water from the stream is channeled until it reaches a difference in dimensions between these mentioned values, according to the slope of the stream.

It is an object of the invention to obtain energy electric starting from the originated by the rotation of a rocker by the weight of water at points distant from the axis of rotation.

Background of the invention

Since time immemorial they have known each other hydraulic devices of the "ferris wheel" type used for raise or draw water from wells.

Paddle wheels are also known which are moved by the current of the rivers to obtain energy or rotational movement on an axis that drives other elements mobiles for a given application, such as mills oil or wheat, arranged on the banks of the rivers Quick.

In a more advanced industrial application, it harness the energy of large waterfalls to move the turbines of power plants of this type.

In some cases small jumps are taken advantage of water to fill the buckets of a ferris wheel from above, thus obtaining, by gravitational action, the continued turn in the axis of rotation of the bucket carrier wheel.

Description of the invention

In general, the hydraulic rocker for generate electricity, object of the present invention, is constituted by an oscillating structure around an axis horizontal, existing in the ends of the rocker two deposits  which are filled alternately by the water of the stream, existing drain valves, adjustable opening, at the bottom of said deposits to get that while one of the deposits is full, the other empties, taking place immediately the change of rocker position, thus achieving an alternative movement continued.

Due to the weight of the water that fills one or the other deposit, and also taking into account that both deposits are they find at the ends of the rocker and that it has a certain length to produce a high torque, this force vertical due to gravity, is the one used to drive hydraulic oil cylinders that have been installed in the low part of the rocker and that are actuated by the movement intermittent thereof, having the rod of said cylinders the point of application close to the axis of rotation of the rocker, for so that the resistance arm is small in proportion With the power. Both hydraulic cylinders occupy a position similar to the vertical plane through the axis of rotation of the rocker or fulcrum of the balancing device.

Water from the stream is channeled to that pours at a point located superior to the rocker and in a vertical plane through it, becoming the own arms in channels that lead the water to the respective deposit, depending on the angular position acquired by the rocker, in one way or another and because there is a plate dividing vertical that incommunicates these channeling of each other water on the arms In this way, if the deposit of the Left has been filled, swinging and water from the channel occurs input is pouring into the right channel to fill the deposit on this side. Balancing occurs as a result of the existence of an adjustable drain located at the bottom of the tank opposite.

Each balancing of the device produces a oil stroke that is sent to an accumulator inside the which are spherical balls filled with air or another gas to create a pneumatic mattress inside the accumulator. This air or gas is compressed upon receiving the oil strokes sent by hydraulic cylinders.

The hydraulic cylinders have two check valves: one in the pressure circuit and one in the of return or aspiration. These valves allow the entry of oil when the cylinder rod is rising, being in this phase the open intake valve and the circuit valve closed pressure. When the stem drops, the suction circuit and the pressure circuit is opened by passing the oil to the accumulator.

The volume of the accumulator will be the one necessary to that the emboladas, which are discontinuous, do not produce oscillations of pressure in the accumulator. Once the Regulator pressure in the accumulator, the pressure circuit is opened that drives a hydraulic motor and this hydraulic motor spins the electric current generator producing electric power that is sent to the network.

To resolve the volume differences of oil that can be produced by compressing the air or gas from the balls in the accumulator, there is the corresponding deposit communicated with the atmosphere, which feeds the hydraulic cylinders and receives the oil once it has passed through the engine hydraulic.

The low cost of the entire installation allows the sale of electric energy produced in streams is profitable whose contribution flows are between 200 and 2000 l / sec.

With this system you get clean energy because It is not polluting and also the environmental impact is minimal since that water can be channeled through pipes that are they will install in the stream beds, buried for not modify the environmental environment of the stream.

To facilitate the understanding of characteristics of the invention and forming an integral part of this Descriptive report, accompanying some sheets of plans in whose figures, with an illustrative and non-limiting nature has been represented the next:

Brief description of the drawings

Figure 2. - It is a plan view of what is shown in figure 1.

Figure 3. - It is a longitudinal elevation view, of the same hydraulic rocker of figure 1 forming part of the electricity generating facility.

Description of the preferred embodiment

Referring to the numbering adopted in The figures, we can see how the hydraulic rocker to generate electricity, which the invention proposes, is constituted by the rigid structure of arms (1) and (2) that can oscillate around of the horizontal axis (3), being located at the ends of the arms (1) and (2), the respective tanks (4), which are provided with adjustable valves for discharging water from of the feed channel (6) that will fill these tanks (4) of alternate form.

The arms (1) and (2) of the rocker arm become in channels so that the water coming from the feed channel (6) arrive at the respective deposits (4), being held incommunicado each other both channels due to the existence of the vertical plate dividing (7). When the hydraulic rocker is in horizontal position, the dividing plate (7) is arranged vertically above the horizontal axis of rotation (3) and also remains centrally located below the water outlet of the canal power (6).

With this arrangement, when the rocker is find, for example, in the position shown with a continuous line in figure 1, that is, with the tank (4) of the arm (1) full of water and in the lowest position, the dividing plate (7) is it is turned to the left and therefore the water coming of the feed channel (6) is received in the tank (4) of the right for it to fill, the regulating valve being (5) of this deposit, closed. While the deposit on the right is filling, the tank (4) on the left is emptying since previously the valve has been opened regulation (5) so that the controlled discharge occurs in this deposit (4) on the left.

When the hydraulic rocker changes position due to the weight of the water contained in the tank that is full, this energy is used to drive the hydraulic cylinder (8) installed in one and the other arm of the rocker, being thus operated alternately in each swing.

In figure 2 it has been referenced with the number (9) the drainage channel into which the contents of the tanks (4) by their respective regulating valves (5), said channel (9) being arranged under them. The reference (10) designates the spillway of the feed channel to drive the leftover water that goes to the discharge mouth (11).

Figure 3 shows the hydraulic rocker and its related elements (hydraulic cylinders (8)), forming part of an installation where the oil accumulator is located (12) that receives oil through the pressure circuit (13) of the emboladas of the hydraulic cylinders (8) during balancing, reaching a regime pressure to drive the hydraulic motor (14) that provides the rotation of the electric current generator (15) to Send to the network.

Reference (16) designates an oil tank in communication with the atmosphere to compensate for variations in volume of oil produced by compressing the air in the accumulator (12) and in which hydraulic oil is also received hydraulic motor return (14). The return circuit is referenced with the number (17) and feeds without pressure to the hydraulic cylinders (8), in their intake stroke when extended its stem as a result of balancing.

The embolada of oil under pressure, produced by the cylinder (8) that retracts as a result of the power torque that exerts the weight of the water contained in the tank (4) that is found above, determines that, when it descends, a high force to retract the rod of the respective cylinder (8), because it is anchored with a resistance arm short.

The accumulator (12) includes a pneumatic mattress materialized by a plurality of spherical balls (18) filled of air or other gas, which are compressed every time a embolada of the hydraulic cylinders (8). The reference (19) designates a perforated sheet found at the base of the container that materializes the accumulator (12) to prevent the balls (18) interfere with the pressure and return lines of the Hydraulic circuit. Of course the hydraulic cylinders (8) they have two check valves, one in the circuit pressure (13) and another in the return or suction circuit (17), thanks to which the oil inlet in the cylinder is achieved hydraulic (8) when its stem is rising, in the phase of intake, keeping this valve open as long as the Pressure circuit is closed. When the stem descends the intake valve closes and the one of the pressure circuit to give oil to the accumulator (12).
