Abstract

Rotary wind turbine belongs to the field of energy, agriculture. The effectiveness of this development is to increase power, reliability at startup, the possibility of a planned and emergency stop. The device is a module consisting of a shaft on which at least three blades containing ailerons are fixed, part of which under the influence of wind becomes a weather vane, passing air flow, part is fixed by stoppers, creating the maximum possible resistance to air flow. This results in torque on the shaft. To increase power, additional blades are attached to the module in both axial and radial directions. At the same time, to increase rigidity and reduce material consumption, the blades are attached to each other and suspended from the shaft by cables, as well as are voluminous (Figs. 1, 5, 16). To increase reliability and relieve internal stresses in the structure, rollers are installed on the blades, which roll along treadmills (Figs. 4, 5). To increase the efficiency, the ability to control the operation of the rotary engine, a locking device is installed, connected by means of flexible communication and two-arm levers with clamps, a manual control lever, which makes it possible to stop the engine in a planned manner, and a force sensor, which makes it possible to make an emergency stop automatically when it reaches wind speed of a critical value (Fig.3, 12, 13). To start the rotary wind turbine, an energy accumulator and a starter connected to the feedback shaft are installed (Fig. 16). To reliably stop the rotary wind turbine, the latches are rotated at the command of a manual drive or a force sensor, allowing all ailerons to become in a vane position. For reliable start of the wind turbine, the clamps are equipped with stoppers that enable the ailerons to move from the vane position to the working position (Fig.6, 7, 8, 9, 10, 11).

Description

1. FIELD OF TECHNOLOGY TO WHICH A USEFUL MODEL IS.

Rotary wind turbine is used in various sectors of the economy when using renewable energy sources (wind).

A rotary wind turbine can be used in the national economy to draw water from wells into water towers, provide electric energy to farms, buildings, and mini-factories for processing agricultural products directly in the field; as power mechanisms that completely replace expensive combines and tractors (especially the need for rotary wind turbines arises when working in rainy weather and after rain, when the soil is still wet and heavy machinery gets stuck in it) with appropriate refinement of trailed (mounted) equipment. This will make it possible to attract plants to the production of new cheaper equipment than traditional combines and tractors.

Rotary wind motors can be used as engines of vehicles, since they work regardless of the direction of the wind. To do this, the rotary installation must be put on a wheeled chassis. And in river transport, the rotor installation can be used as a power unit for the ferry.

In mountainous areas, rotary wind turbines can be used as power plants for lifts at tourist camps.

Rotary wind motors can be used as power units of stone crushing machines for processing stone, as well as for converting glacier ice into water by installing them on rocks.

Country cooperatives can also use rotary wind turbines for their own purposes (water intake from wells, lighting of country houses).

Using a rotary wind turbine, wind energy can be used to break down water molecules into oxygen and hydrogen for their further use in the national economy.

Rotary wind turbines together with generators can be used as a source of electric energy as part of RAO UES, which will save gas, coal, oil, diesel fuel, and put additional energy facilities for prevention and repair.

2. BACKGROUND OF THE INVENTION

In the journal "Science and Life" - 2001, No. 1, the article "Wind turbine with a waving rotor" shows a wind turbine developed at the Research Center named after M.V. Keldysh. The "heart" of the wind turbine is a four-blade rotor. It contains a central body with two pairs of mutually perpendicular shafts installed in it with gears that are connected to the blades. The power consumer is kinematically connected to the rotor through a planetary gear, also mounted on the central body.

Before starting work, the blades are installed in a certain way: two are lifted vertically upwards, and the other two are placed horizontally and directed in opposite directions. Under the influence of wind, the blades begin to describe complex three-dimensional trajectories resembling spatial “eights”. From the output shaft, torque is transmitted to the power consumer shaft.

The design is oriented to the wind by an air vertical rudder of the feathering mechanism. It is installed perpendicular to the supporting platform using a balancing mechanism, including a pair of screw-spring-loaded nut, movable wing and cable. With a squall wind (21–25 meters per second), a movable wing located under the tail unit puts the unit in a position where the blades provide the least aerodynamic resistance to the wind. When the wind speed decreases, it is set to its working position.

In the journal "Science and Life" - 2003, No. 3, the article "Tower of Wind Power Modules" gives a wind power installation developed at the Central Aerohydrodynamic Institute - TsAGI, "Module" and multi-module installations "Venets" and "Tower". Wind turbine "Module" with an improved aerodynamic design and improved layout. It is equipped with an annular fairing with profiled annular blades that create a swirl of the wind flow at the entrance to the wind wheel.

The multi-module wind power installation Venets is designed to supply electricity to individual houses.

The multi-module wind tower "Tower" can change the height and power depending on the number of "Modules" mounted on the central body.

In these structures, the wind wheel is placed in the annular fairing and mounted on the central body using profiled blades. The blades are designed so that they create a preliminary twist of the wind flow on the approach to the wind wheel.

Known high-speed orthogonal multi-blade wind turbine for energy (hereinafter: wind turbine) from a renewable wind source for energy is accelerated to a certain speed from an external source of mechanical or electrical energy. At a speed of 10 to 30 m / s., Due to the special aerodynamic shape of the blade, a pulling force arises directed towards the general direction of air movement. Suspension of the wind turbine can be carried out as an electric locomotive or magnetic with linear generators located along the route.

- the ability to start a rotary wind turbine after it stops;

- rotary wind turbine does not need to install a weather vane;

- increase in reliability and stable operation.

The task of converting wind energy using the proposed rotary wind turbine is achieved by the fact that:

to obtain high power, the proposed rotor is a module to which you can attach additional blades 2 and shafts 1 in height and in the radial direction (figure 1);

- the rotor blades 2 contain rotary planes - ailerons 3, which freely rotate around their own axes (Figs. 1, 2, 3, 4, 5);

- the blades 2 are equipped with clamps 4 (2, 3, 6, 7, 8, 9, 10, 11), which orient the ailerons 3 in the plane of the blades 2 themselves, holding them in this position within the angle of rotation of the rotor from 0 to π radian, thereby limiting the rotation of the ailerons 3 around its own axis, which creates wind pressure on the blade within the angle of rotation of the rotor from 0 to π radians;

- in order to eliminate technogenic accidents associated with the action of possible air storm flows, the rotor wind turbine is equipped with a locking device 7 (Fig.2, 12, 13) and a force sensor (Fig.14 is an option), with which, when critical (storm ) the air flow velocity unlocks the latches 4 (Fig.2, 3, 6, 7. 8, 9, 10, 11), i.e. rotate, allowing the ailerons 3 to take the vane position, as a result of which the air flow freely passes through the blade 2 - the force acting on the blade 2 decreases sharply, the rotor stops;

Figure 1 shows a rotor containing a shaft 1, blades 2, ailerons 3. The direction of the wind is shown by straight arrows: long arrows show the free passage of air flow through

blades whose ailerons are in the vane position; short arrows show that the air flow does not pass through the blades and creates pressure on the blade.

The curved arrow shows the direction of rotation of the rotor, and independent of the direction of air flow.

Bold lines show the rotor module (shaft 1, blades 2, ailerons 3). Thin lines show additional shaft 1, blades 2, ailerons 3 to obtain high power. Additional blades are attached to the module both in height and radially.

Figure 2 shows a rotary wind turbine (front view). The blades 2 are fixed on the axis 1. Aileron 3 (to the right of the axis) is pressed against the stopper of the clamp 4 under the action of the air flow, which increases the surface area of the blades 2 to the maximum, creating maximum force causing torque on the shaft 1. Aileron 3 (to the left of the axis ) the air flow is pressed from the latch 4 and is in the vane position, which reduces the area of the blade 2 to a minimum, allowing air flow to freely pass through the blade 2. The latches 4 are fixed to the blades 2 and connected by cables 6 through two shoulders levers 5 with a movable the washer 8, which is in the upper position. The movable washer 8 has the ability to move along the shaft 1, making a rotational movement with the shaft. Detail pos. 7 is a hollow cylinder that can be moved along the shaft 1, kinematically connected with the manual control lever 9 and force sensor 10. The combination of parts pos. 7 and the movable washer 8 is a locking device, and the detail pos. 7 is the moving part of the locking devices. When the shaft 1 is rotated together with the blades 2, the movable part 7 of the locking device does not rotate. The lever 9 and the force sensor 10, acting on the movable part 7, move the movable part 7 of the locking device to the lower position, and it presses on the movable washer 8, moving it to the lower position. The movable washer 8 pulls the cables 6 along, turning the two shoulders levers 5 and the latches 4. The cables 10 hold the blades 2 in suspension. Dashed lines show the position of the control lever 9 and the movable part 7 of the locking device after moving them.

Figure 3 shows a rotary wind turbine - top view: four blades 2, two ailerons 3 on each blade, two clamps 4 on each blade, dotted lines show the positions of the blades

2 and ailerons 3 when the rotor rotates. Ailerons 3, which are within the range of the rotor angle from 0 to radians, are pressed against the clamps 4 under the action of the air flow (shown by arrows), which creates the maximum windage of these blades. Ailerons 3 passing through the position of the angle π under the influence of the air flow rotate around their axes (shown by curly arrows) and move away from the latches 4, becoming in the vane position. Ailerons 4 located within an angle greater than π to 2π are already in the vane position, which reduces the windage of the blades 2 to a minimum.

Figure 4 shows the rotor, the blades 2 of which are equipped with rollers 11 that roll along the treadmill 12. Such a scheme can significantly reduce internal stresses, as well as reduce the amount of material of the power parts of the blades, without reducing strength. Such a scheme is acceptable when designing high-power wind turbines.

Figure 5 shows a rotary wind turbine mounted on supports 13. The blades 2 are suspended on cables 10 to the shaft 1. The treadmill 12 is mounted on the supports 13. The blades 2 are equipped with rollers 11 that roll along the treadmill 12. Such a scheme is acceptable for low surface wind flows.

Figure 6 shows the latch 4 is a front view. The dotted lines show the positions of the stopper 17 and the lever 18 after rotation (shown by a curly arrow).

7 shows the latch 4 is a side view. The housing 16 in the form of a sleeve is placed on the axis 15, which is rigidly fixed to the support 14. To the housing 16 the lever 18 is rigidly fixed and the stopper 17 is pivotally fixed. The coil spring 19 is mounted on the axis 15 and holds the housing 16 in the working position. The coil spring 20 holds the stopper 17 in an upright position. The letter "A" indicates the front surface of the stopper 17, the letter "B" is the rear.

On Fig shows the latch 4 is a side view. When starting the wind turbine from an external source of energy (after stopping), ailerons 3 located in the vane position within the angle of rotation from 0 to π radians begin to move in the composition of the blade and when the blade passes the line corresponding to the angle π radians under the influence of the incident air flow of the aileron remain in the vane position and begin to lag behind the blade, while pressing on the stoppers 17 from the surface "B" and turn

stops 17. In Fig. 8, this moment is captured (ailerons and blades are not shown). This makes it possible for the aileron to take its initial position to automatically resume the rotational movement of the rotor.

In figures 9, 10, 11, kinematic diagrams of the clamp are shown for a more complete understanding of FIGS. 6-8.

On Fig, shows a kinematic diagram of the moving parts of the rotor in the initial state. From the force sensor and lever 9, a signal to stop the rotor is not received. The movable washer 8 is in its highest position. The movable part 7 of the locking device is in its highest position and is not engaged with the movable washer 8. The spring 19 holds the latch 4 in the working position.

On Fig shows a kinematic diagram of the parts of the rotor, after the signal from the force sensor or from the lever 9. When a signal is supplied from the force sensor or from the lever 9, the movable part 7 of the locking device moving down, presses on the movable washer 8. Moving washer 8, moving down, pulls the cable 6, turning the two-arm lever 5 (counterclockwise), turning the lock 4 (clockwise), stretching the spring 19.

On Fig shows a force sensor (option). The air flow acts on the sail 23, which moves along the guide 21, compresses the calibrated spring 22, pulls a cable 24, which pulls down the movable part 7 of the locking device.

On Fig shows a diagram of a wind turbine with an installed battery and a starter connected by feedback (shown by arrows). To start the wind turbine at the command of the operator, the signal (electrical, mechanical, hydraulic, etc.) from the battery 29 is fed to the actuator - starter 30, which drives in a rotational motion. As soon as the ailerons of one of the blades are pressed against the stoppers of the latches in the sector of the angle of rotation of the rotor from zero to 180 °, the rotor will begin to rotate already from the air flow, and the starter 30 is disconnected from the battery.

On Fig shows the blades, on the left - in the form of a flat structure, on the right - in the form of a three-dimensional structure, for example, a parallelepiped.

5. IMPLEMENTATION OF A USEFUL MODEL.

The utility model can be implemented:

- as a source of electrical energy for feeding garden houses,

- as a source of electricity for powering mini-plants for processing agricultural products,

- as a source of electrical energy for powering water supply pumps from a well to a tower,

- as a power plant (instead of tractors and combines) together with special equipment for working on agricultural fields for tillage, sowing, harvesting;

- as a source of electrical energy for powering stand-alone farms;

- as an integral part of the unified energy system of RAO UES.

WORK OF A ROTARY wind turbine.

In the initial state, the lever 9 (Fig.2, 12) is in the lower position, the movable part of the locking device 7 (Fig.2, 12) is in the upper position, the latches 4 (Fig.2, 6, 9) are in the working position. Solid lines (Fig. 2) indicate the initial position of the moving parts, and dashed lines indicate their position after moving under the influence of force.

With the advent of the wind, the ailerons 3 take the load first, which begin to rotate around their axes and press against the latches of the 4 blades, which are within the angle from 0 to π radians.

The rotation of the ailerons 3, the blades 2, located within the angle of rotation of the rotor from 0 to π radians is limited by the latches 4 (figure 2, 3) mounted on the blades 2. Ailerons 3 of the blades 2, located within the angle of rotation of the rotor from 0 to π radians (we take the angle φ equal to zero in the rotor position, in which the plane of one of the blades is parallel to the airflow velocity vector, and the direction from the rotor axis to the end point of the blade is opposite to the airflow velocity vector), turning under the influence of the wind, the latch stops ami 4 (figure 2, 3), forming a continuous surface of the blade 2 (figure 2, 3). Now the blade 2, which is within the angle of rotation of the rotor from 0 to π radians, perceives the load of ailerons 3, which leads to the appearance of torque on the rotor shaft. And since the diametrically opposed blades 2, located within the angle of rotation of the rotor from π to 2π, move against the action of the air flow, their ailerons 3 are rotated,

moving away from the latches 4, and take a vane position, in which their planes become parallel to the air velocity vector (figure 2, 3). Resistance to wind of these blades is minimal - air flow passes through the blade between the ailerons.

Thus, on the blades 2, which are within the angle of rotation of the rotor from 0 to π radians, a force is created, which is the source of torque. The rotation of the rotor becomes continuous in the presence of air flow and the number of rotor blades is not less than 3.

STOP THE ROTOR.

In order to carry out a planned stop of the rotor, a locking device 7 (Fig. 2, 12, 13), a manual control unit 9 (Fig. 2, 12, 13), kinematically connected, for example, by a cable 6 through two shoulders levers 5 with clips 4 (Fig. .2, 12, 13). Instead of two-shouldered levers, you can use guide blocks through which the cables 6 are thrown.

The rotor is stopped by the operator as follows. Acting on the lever 9 (Fig.2, 13), the operator’s effort is transmitted to the movable part of the locking device 7 (Fig.2, 13), which, moving down along the rotor shaft 1 (shown by the arrow), carries the movable washer 8 (Fig. .2, 13). The movable washer 8 transfers the force through the cables 6 rigidly fixed to it, two shoulders levers 5 to the latches 4 of all rotor blades.

The latches 4 rotate around their axes, and with them the stoppers 17 (Figs. 7, 10), freeing up the path for rotation of the ailerons of the blades, which are within the angle from 0 to π radians. Under the action of the air flow, the ailerons 3 rotate, occupying a weather position. The resistance of the blades 2, which are within the angle of rotation of the rotor from 0 to π radians, becomes minimal - the torque disappears, the rotor stops.

To resume rotation of the rotor, the lever 9 is transferred to its original position (figure 2, 12). The return spring 19 (Fig.6, 9) returns the latch 4 to its original position. Using the battery 29, the starter 30, connected with the rotor by positive feedback of Fig. 15, the rotor is given a rotational movement at an angle at which the nearest blade 2, which is within the angle from π to 2π radians, will occupy a position within the angle of 0 radians, where there will be a stop of the rotation of the ailerons 3 clamps 4 (figure 2), which is necessary for

the appearance of torque - the source of further work of the rotor.

WORK OF THE ROTARY WIND MOTOR IN EMERGENCY MODE.

In order to eliminate technological rotor accidents during air storm flows, it is envisaged to install a force sensor (Fig. 14 is an option). The operation of such sensors can be applied on various physical methods of action (electrical, mechanical, etc.). Kinematically, the force sensor (FIGS. 2, 12, 13) is connected to the latches 4 through the movable part of the locking device 7, the movable washer 8, the cables 6 and the two shoulders levers 5.

When the airflow rate is equal to the storm, the force sensor (Fig. 14) gives a signal in the form of a force acting through the movable part of the blocking device 7, the movable washer 8, cables 6, two-arm levers 5 on the clips 4 (Fig. 2, 12, thirteen). The work of the listed parts and ailerons of 3 blades 2, which are within the angle of rotation of the rotor from 0 to π radians, is similar to work with a scheduled stop by the operator, i.e., all ailerons of 3 blades of 2 rotors, turning, will occupy a vane position. The resistance to the air flow of all the blades in this case is almost the same and minimal. The rotational moment of the blades disappears - the rotor stops. The total rotor load during a gale remains below critical (non-destructive).

Since all the ailerons of all the blades are deployed (there is no torque), to further resume the rotation of the rotor, it is necessary to turn the force externally (not shown in the figures) by such an angle that the nearest blade located within the angle from π to 2π radians moves to the angle is more than 2π radians, i.e. in the first quadrant, where the ailerons will be captured by the air flow and press them against the stoppers 17 of the latches 4 (Figs. 2, 3), which means an increase in the surface area of the blade, which in turn will lead to the appearance of torque. The rotor begins to spin.

The operation of the latch during rotation of the rotor.

The movable parts of the clamps are held in position by the return springs 19 and 20 (Fig.6, 9). This state is maintained throughout the entire rotation time of the rotor.

Under the action of the air flow, the aileron is pressed against the latch into the front surface (A) of the stopper 17 (Figs. 7, 10). This creates a windage of the blade, which is within the angle from 0 to π radians.

The blade rotates with the shaft, performing work only to the point corresponding to the angle π radians. And at the same time, diametrically opposed blades with minimal windage, located within an angle from π to 2π, rigidly fixed to the shaft, move against the action of the air flow force. A sharp decrease in the windage of the blade occurs when the blade passes the point corresponding to the angle l radian, since the air flow will act on the blade from the other side and the ailerons move away from the latches and take the vane position. Air flow freely passes through the blade between the ailerons (figure 3).

The operation of the latch while the rotor is stopped by the operator.

In the initial position, all the ailerons of all the blades, which are within the angle from 0 to π radians, are pressed against the front surface (A) of the stopper 17 of the retainer 4 (Fig.6, 9), creating a torque on the rotor shaft. In order to stop the rotor, the operator moves the lever 9 (Fig.2, 13). The lever 9 at the other end acts on the movable part 7 of the locking device. The movable part 7 of the locking device, moving down, presses on the movable washer 8, which, using the cables 6, rotates the two shoulders levers 5 (Fig.2, 13). The other shoulders of the two-arm levers 5 through the cables 6 pull the levers 18 of the latches 4 (6, 9). The housing of the latch rotates around its axis, and with it the stopper 17 also rotates (Figs. 7, 10). The stopper 17 disengages from the aileron, freeing him the way to make a turn under the influence of air flow. Turning, the ailerons of the blades, which are within the angle from 0 to π radians, become in the vane position. Air flow freely passes through the blades, the torque disappears - the rotor stops.

The operation of the latch from the action of the force sensor.

In the initial position, all the ailerons of all the blades, which are within the angle from 0 to π radians, are pressed against the front surface "A" of the stopper 17 of the retainer 4 (6, 9), creating a torque on the rotor shaft.

When the wind is amplified to a value at which the rotor can be destroyed, a signal in the form of force enters the movable part 7 of the locking device (FIGS. 2, 13), moving it down.

Further, everything happens similarly to the above, when the rotor is stopped from the action of the operator on the lever 9.

The operation of the latch when resuming the rotation of the rotor.

Regardless of the method of stopping the rotor, the resumption of its rotation occurs according to one scheme. The circuit of the latch is as follows. The operator returns the lever 9 (figure 2, 12) to its original position (which corresponds to the disappearance of the signal of the force sensor as a result of attenuation of a gale). The movable part 7 of the locking device rises, relieving pressure from the movable washer 8 (Fig.2, 12). The spring 19 of the retainer (Fig.6, 9) returns to the initial position of the clamps 4, two shoulders levers 5, a lock washer 8 (Fig.2, 12).

As soon as all these parts have taken their initial position, it is necessary to turn the rotor from the external energy source of Fig. 15 (for this purpose, the battery 29 and the starter 30 are connected with the rotor by positive feedback) by an angle at which at least one blade from an angle from π to 2π would go through zero (2π) degrees, where it would now be within the angle from 0 to π radians. Here, under the action of the air flow, the aileron will be pressed against the clamp, i.e. to the front surface (A) of the stopper. Torque appears - the rotor resumes rotation from the air stream. What happens to the blade parts at the same time at the opposite pole, i.e. when it passes from the angle π radians? After the rotor is forced to stop, the ailerons of the blades located within the angle from 0 to π radians are located behind the clamps, i.e. now from the side of the surface (B) of the retainer stopper (Fig.8, 11). When the blade passes the point corresponding to π radians, the blade changes the direction of motion in the opposite direction. Now the air flow presses the aileron to the surface "B" of the stopper (Fig.8, 11). The stop deviates and passes the aileron. Aileron takes position from the side (A) of the stopper, i.e. the starting position at which the torque appears.

Under the action of the spring 20, the stopper 17 (Fig.6, 9) of the latch returns to its original place.

Thus, this design has high reliability, allows you to create a high-power wind turbine with

minimum material consumption, as well as the ability to control the start, scheduled and emergency stop.
