The invention relates to the kinetic energy of the flow of liquid or gas into the energy of mechanical motion and can be used in wind farms, otronicon plants, hydroelectric plants and other similar devices.

The famous "thunk kinetic energy of the flow of the continuous medium into mechanical energy(EN 2338923 C1), in which the energy of the flow is converted into the energy of mechanical motion linearly oscillating cage with established therein aerodynamic plates (plans). This Converter provides more power than the inverter rotary type. However, experimentally it was found that its capacity can be increased. This solution can be taken as a prototype.

The present invention is to increase develop the vibrational transducer of the type of power.

This task is solved in that in the transmitter of the kinetic energy of the flow of the continuous medium into mechanical energy, comprising a housing, a movable yoke with a set of aerodynamic plans, the mechanism kinematic link between plans, limiters angles of rotation and batteries mechanical energy inside the case with freedom of linear movement between the batteries mechanical energy ei is nitella ferrule installed in her non-rotating aerodynamic plans.

Figure 1 presents the scheme of the Converter.

Figure 2 presents the scheme of the plan, is rotated relative to the holder at the angle α.

Figure 3 presents the scheme of the plan, is rotated relative to the holder at the angle-α.

Converter (top view) consists of a housing 1, through which the translational kinematic pair 2 relies ferrule 3. In the cage with freedom of rotation between the angular constraints 4 and 5 are placed aerodynamic profiled plans 6 connected between a kinematic mechanism 7, providing sameness of their rotation angles. Axis rotations plans shifted from the centers of pressure (CSD) in the direction of the shank at a distance of l1. The total center of mass (CM) plans and mechanism kinematic connection is shifted from the axis of rotation in the direction of the shank plans at a distance of l2. The yoke 3 has the freedom linear reciprocating motion between the battery 8 and 9, the mechanical energy which is mounted on the chassis 1 in the plane I-I axis of rotation plans. (The plane I-I perpendicular to the plane of the sheet.) The ferrule 3 is set as the device 10 due to the load. From the extremities of the aerodynamic plans clip 3 installed in the housing in the forward kinematic pairs 11 with freedom of linear movement between the battery 8 and 9 of the ferrule 12. It placed neversaydie the aerodynamic plans 13 and the device 14 due to the load. Plane plans 13 perpendicular to the direction of movement of the shroud 12. Plans 6 and 13 are optimal for a given schema thickness, elongation and profile sections, for example, is symmetric. Batteries mechanical energy 8 and 9 can be performed, for example, in the form of a pneumatic spring. The design of the translational kinetic pair of suspension clip is defined by two main requirements - strength and low friction. Geometric and strength parameters of the plans are determined by the ambient medium (gas, liquid), the flow rate and the dimensions of the Converter.

The proposed Converter is as follows.

When the flow stream environment plans 6, oriented to the vector of its velocity VBunder some subcritical angle of attack, i.e. the angle between the direction of the velocity vector of the flow and the plane of the plan α (figure 2), on each plane, as is known from aerodynamics (see, for example, Stasenko A.L. Physics of flight, Moscow, Nauka, 1988) is applied to the center of pressure of the aerodynamic lifting force:


where ρ is the specific density of the medium,

S - streamlined area plan

Withy- the lift coefficient that depends on the angle α.

The direction of the lifting force is determined by the sign of the angle of attack. A phenomenon similar to the emergence of a lifting force on the wing Letatlin the machinery.

Under the action of the total force FΣ=nFawhere n is the number of plans in the holder 3, the yoke moves in the direction of the force FΣfor example, in the direction of the battery 8, with acceleration


where m is the mass of the shroud with the elements, develops the linear velocity V1(t)=∫adt and accumulates kinetic energy.

When this rod mechanism 7 under the action of torque

pressed against the stopper 4, which provides a constant angle of attack α.

At the moment of approach of the clip 3 to the battery 8, the ferrule 3 bumps on the shaft of the battery 8, moves it, giving the battery the accumulated kinetic energy, and is retarded. At the same time, the center of mass of the plans continues to move by inertia in the direction of the force FΣthat leads to the development relative to their axes of rotation, the moment of inertia

where W(t) is the acceleration braking directed opposite to the moment Mn.

If the structural measures provided condition

plans will be rotated in the holder 3 so that the angle of attack is changed to the opposite sign. Because the plans are interconnected kinematic nexus 7, they rotate at the same angles. In the process SEL is of the cage and rotation plans the spindle mechanism 7 stumbles upon the angular limiter 5, which limits the angle of rotation plans construction-specified value.

At some point in time, the kinetic energy of the shroud 3 is completely absorbed by the battery 8, the movement of the cage and turn the plans are terminated. At this point, plans are rotated relative to the holder 3 by the angle minus α(figure 3). From that moment the power of the FΣreversed - minus FΣ. At the same time the battery 8 gives the absorbed kinetic energy of the ferrule 3 and she is using her battery energy and impact force FΣmoving to the opposite side of the housing 1 with velocity V2(t). During its approach to the battery 9 to happen-like phenomena taking place in the approach to the battery 8, only now the angle of attack plans 6 is changed to plus α. So the process is recurrent, i.e. the holder performs a linear reciprocating motion between the battery 8 and 9. In the limit develop its speed will be


where K- the damping factor,

and the maximum capacity

The average for the period of the oscillatory motion power

At idle, i.e. no load on the device 10, the movement of the shroud damping is created t is like forces of friction elements of the holder 3 about the environment. If the device 10 connection with the load attached, for example, to a linear generator, the Kwill mainly be determined by the speed impedance of the generator.

In each phase of movement of the holder 3 with each plan 6 falls rejected on the angle of attack with respect to its initial direction of flow of the ambient environment. This thread washes plans 13 of the clip 12 (2, 3) and also develops aerodynamic lifting force, but opposite in relation to the lifting force plans 13 of the casing 3 of the sign, as the angle of attack plans 13 is opposite in sign to the angle of attack plans 6. Under the action of this force, the holder 12 moves in the direction opposite to the direction of movement of the holder 3, and at the time of braking of cage 3 stumbles upon a battery of mechanical energy, gives him the accumulated kinetic energy and is retarded. At the time of changing the direction of movement of the shroud 3 is changed due to the change of angle of attack plans 6 on the opposite corner of the wrapping thread plans 13 is changed to the opposite direction occurred to them lifting force (figure 3), a battery of mechanical energy gives the accumulated energy of the ferrule 12, and it is under the action of the lifting force has the opposite direction and is given by the energy accumulator is moving in the opposite direction. This process period of the automatic repeats. With proper dimensioning of the casing 3 with the parameters of the shroud 12 both carriers move in antiphase. Antiphase movement due to the simultaneous impact on plans 6 and 13 are equal in magnitude, but oppositely directed aerodynamic forces. In turn, the synchronicity of the forces is determined by the principle of continuity of flow. The interaction of the flow with plans 6 and 13 is similar to the interaction of the guide vane of a gas turbine with its impeller. The power developed by the holder 12, with the right ratio of its parameters clip 3 will be equal to the power cage urashima clip 12 capacity can be transferred to the load through the communication device 14.

Thus, the technical effect of the invention is that the total capacity of the inverter is twice the power Converter prototype, because at the same time in one device are two groups aerodynamic plans. The design of the clip 12 is simpler designs clip 3.
