Description

Technical field

The invention relates to a turbine with valves, which is used in the use of energy from the movement of wind, water, water vapor, liquids and gases for the extraction of electricity, drive pumps, mechanisms and other equipment in stationary and mobile conditions, and as well as vehicles.

BACKGROUND OF THE INVENTION

A wind engine (valve turbine) is known, which comprises in combination a blade attached to a rotating central axis, supporting means for mounting the wind-driven blades to convert wind flow into useful mechanical or electrical energy. These blades have at least one pair of parallel space frames and at least one movable flap fixed between the frames. The blades also include restraints mounted between frames that serve to limit the central movement of these valves. When the flap is driven by the wind stream and is moving in its opposite direction, the valve actuates it as it oscillates and rotates to stand parallel to the wind direction. The wind engine also includes a control and control system for limiting the rotation of the valves to the wind flow. This control system includes stop-control controls which are located between the frames and are capable of being centrally actuated by direct contact with the wind stream and maintaining a speed corresponding to the wind flow rate. The stop control system is connected to said valve to synchronize between the movement of the valve against the wind flow velocity, which must be at a predetermined range, which will prevent the valve from overloading and falling apart. The supporting structure of the windmill is made of adjustable tensioners / 1 /.

The disadvantages of the known wind engine are the complex system for maintaining and synchronizing the speed of the valves with the speed of the wind flow and the loss of energy due to the complexity of the stop control system. This complicated system increases the cost of construction, especially for the needs of small individual consumers of electricity.

Also known is a wind engine comprising blades to which there are horizontal, vertical, left, right or top and bottom mounted valves relative to the center line of the blades. In addition, the valves can be hung in groups in a spiral or other order. Also, the blades and valves can be made of different geometric shapes and of different materials, such as metal, synthetic materials and the like (2).

Technical nature

It is an object of the invention to provide a simplified design turbine with maximum utilization of wind energy.

The problem is solved by a turbine with valves comprising blades fixed about a vertical rotating central axis, supporting means for fixing and articulating the blades, the blades containing at least one pair of parallel space frames and at least one movable valve, wherein the blades have stop blades. the central movement of the valves as they are driven by the wind flow, and there is also a control and control system with stop control, as well as supporting and stabilizing means. According to the invention, an inertial accumulator (flywheel) is fixed to the vertical rotating central axis between the bilaterally arranged blades, which is also fixedly connected to the blades on its opposite sides. In addition, restraints are provided on the axis of each blade in the middle thereof to provide two-stage control of the rotation of the valves. At the same time, in each blade, the flaps are angled with respect to the centerline of

The limiter is designed as a two-stage controller.

The blades are bent in the form of an extended S relative to the horizontal and vertical axis of the blade, as well as to the axis of the vertical central rotary axis.

Also, the flaps are bent according to the shape of the blades.

The advantages of the turbine according to the invention are that, due to the fixedly fixed inertial accumulator to the rotating central axis, inertia and smooth movement of the central axis are provided during the running stroke. The suspension of the valves, as well as the limiter mounted on them, allows for a more efficient use of the force of the wind flow and provides the possibility of protection of the structure at high wind speeds. Furthermore, the valves are as light and nimble as possible and at very low wind speeds turn the blade into a dense body only at the moment of the frontal pressure of the wind flow on the blades, after which the valves are opened due to lack of frontal pressure only by the resistance of the air, in which they move, and as a result of inertial rotational motion, the blade becomes a wing with minimal frontal resistance. This increases the efficiency of the turbine and always ensures one direction of rotation of the blade, regardless of the angle, direction and pressure force exerted by the wind flow.

Examples of implementation

The turbine according to the invention consists of blades 1 made with aperture 2, with the valves 4 of the blades 1 hanging valves 3. The closure of the valves 3 is controlled by stops 5. The blades 1 are suspended relative to the center line of the central rotary axis 7 of groups of two, 180 ° relative to each other, and up to three, 120 ° relative to each other, in a spiral or other sequence along the central rotary axis 7. The blades 1 are bent in the form of a stretched S relative to the horizontal and the vertical axis of the blade itself 1, k as a fail, and the axis of the central rotating axis 7. Depending on the operating environment and its dynamic properties blade 1 together with valves 3 are made of metals, alloys, natural or synthetic materials. At the same time, the blades 1 together with the valves 3 are provided with appropriate design controls and controls that allow them to retain the designed geometric shape to a certain pressure value. If the specified value of the wind flow pressure of the valve 3 is exceeded, it passes freely through the opening 2 and reduces the pressure from the front pressure of the wind flow, used in this case as free energy 9. The inertial forces are maintained by the inertial accumulator (flywheel) 6, the rotation of the turbine is always in one direction 8, determined by the method of attachment of the valves 3 to the blades 1, regardless of the angle, direction and pressure of the wind flow 9 used as free energy.

With the bent blades 1 and, accordingly, of the same shape of the valves 3, for example as the extended S, better aerodynamics and greater agility of the valves are obtained, and hence a better efficiency.

Use of the invention

According to the invention, a valve turbine is used to generate electricity and to locally supply objects away from energy sources, such as power grids, water basins and the like. The construction of small local turbines is easily feasible as it does not require the use of large resources and the use of highly qualified specialists. Such a local turbine can be used in agriculture for irrigation, heating, propulsion of various mechanisms. The turbine can be powered by other types of free energy other than wind flow, for example natural air currents artificially created by solar traps, air tunnels and chimneys, cavities in the bowels of the earth, water currents and other similar sources of free energy. The turbine provides the opportunity to build complex facilities for continuous generation of electricity by accumulating the received electricity from integrated groups of turbines.

It is important to note that, according to the requirements imposed by the free energy used, the blades and valves are made of suitable material, providing the necessary stability and adaptability.

At two wings 180 ° relative to the central axis under the front wind pressure for one revolution, the valves close and absorb wind power only twice, at three wings on one plane the wind exerts its force and produces torque only three times for one revolution, the rest of the movement from the trajectory is idling with the flaps open. Therefore, a flywheel is installed to the central rotary axis - an inertial accumulator that stores energy, at the expense of which the rotating central axis rotates as the idle processes occur when turning. Due to the operation of the flywheel as an inertial accumulator, the valve turbine operates smoothly and maintains the rpm even at low wind gusts.

The rotation of the valve around its axis is not limited by a mechanism in which the valve strikes to transmit the pressure of the wing and rotate it, but with a two-stage regulator, which incorporates springs, regulates the rotation of the valve in two stages. The first stage, at a design speed determined by the wind, the valve silently closes the wing opening, when the calculated wind speed exceeds the valve passes silently through the wing opening and creates an opening through which the wind passes freely. The higher the wind speed, the more the flap rotates at a greater angle and makes a larger opening in the wing and vice versa - at low and medium wind speed the valve tightly closes the aperture of the wing. Due to the two-stage controller, the turbine limits its maximum speed and cannot be damaged in high winds. When the valves are angled at the centerline of the rotary axis, the flap rotation increases, and the process of opening and closing the valve is faster.

Thus, the valve turbine has a simplified construction, operates quietly and smoothly and protects against strong winds, while at the same time not exceeding the design speed.
