The invention relates to a device for converting kinetic energy of wind or water flow into electrical energy.

Known screw, containing mounted on the shaft sleeve with blades [1, 2]. This screw is able to absorb the kinetic energy of wind or water, but not able to generate electrical energy.

Object of the invention is to enhance the functionality of the screw.

The solution of this problem is achieved in that the screw containing mounted on the shaft sleeve with blades, provided with a device for generating electrical energy in the form of a sealed hollow body having end and side walls, with the prisoner in his stationary inductive ring and a movable permanent magnetic element. A device for generating electrical energy is located on the sleeve on the side opposite the blade. A device for generating electrical energy is located in the sleeve between opposite blades. A device for generating electrical energy is located between the sleeve and the blade. A device for generating electrical energy is located in the blade.

Figure 1-3 shows the screws, respectively, with one, two and three blades; figure 4 shows a multi-blade propeller; figure 5 shows a blade with built-in lighting is the group to produce electrical energy; figure 6 shows a device for generating electrical energy, longitudinal section; figure 7 - section 6 along a-A.

The screw contains mounted on the shaft 1 and sleeve 2 with blades 3, a device 4 for generating electrical energy, a housing 5 which is rigidly connected with the sleeve and/or the blade connecting link 6. The blade perceiving the kinetic energy of the wind can take the form of straight or curved plate, and the blade receiving kinetic energy of the water - direct plates or cups. The design of the screw device for generating electrical energy may be positioned on the sleeve opposite the blade (figure 1); between the sleeve and the blade (figure 4); between the opposite (relative to the axis of the shaft) blades (figure 2). You can embed devices for generating electrical energy directly into the blade (figure 5). The case of devices for generating electrical energy is airtight, has a tube shape round, oval, rectangular or other cross section. End 7 and the lateral (side) 8 housing wall is made of a nonmagnetic material. In the cavity of the housing from the side face walls are the dampers 9, made in the form of flexible tubes or springs of a nonmagnetic material. In the middle part of the body still installed inductive number is CA 10. Inductive ring via terminals 11 bred on the surface of the case has the possibility of contact with a fixed (positioned around the shaft) a current collector of an electrical system (not shown). In the building there is a constant magnetic element 12 with the possibility of free movement between the dampers through inductive ring.

Situated in the vertical plane, the screw works as follows.

When exposed to the blade 3 of the kinetic energy of wind or water shaft 1 with a fixed sleeve 2 starts to perform a rotational movement. When the device 4 for generating electrical energy attached rigidly connected with the housing 5 of the connecting link 6 to the hub or the blades (the blades) or embedded in the blade starts to rotate around the axis of the shaft. Due to forces of gravity located in the cavity formed by end 7 and a lateral (side) 8 enclosure walls, permanent magnetic element 12 is in motion, the translational moving between the dampers 9. When moving permanent magnetic element through inductive ring 10 in the latter, an electric current, which is removed from the terminal 11 of the current collector electrical system.

The offered screw is capable of converting kinetic energy of wind or water into electrical energy in terms of the AI excess of gravitational forces on centrifugal forces, acting on the permanent magnetic element. This screw can be used to obtain small amounts of electrical energy. A significant advantage of the screw is its compactness.

The screw can be an integral element of small power plants, toys, tools, entertainment, educational booths for the students of schools and colleges. All this extends the functionality of the screw, as a power device.
