The bands are tensioned on vertical poles of a frame mounted on a rotary base; the tail components are fixed on horizontal rods secured to vertical poles; also the bands are connected with rods in their middle part. ^ EFFECT: raised reliability due to absence of rotating parts and low prime cost, because elastic bands functioning as active components are items of mass production and do not require complicated aero-dynamic surfaces expensive in fabrication. ^ 9 dwg

Description

The invention relates to the field of wind energy, and more specifically, to bladeless dynamic generators.

Known electro-hydraulic dynamic generator [1], consisting of a mechanism for producing colloidal particles, input and collecting electrodes, a power source and a control system.

These generators did not find application, because their disadvantage is the large losses on the generation of colloidal particles, the occurrence of corrosion (erosion), the difficulty in ensuring safety due to the presence of high voltage.

Closest to the claimed technical essence is a generator that implements a method of converting flow energy into electrical energy [2]. The generator is a set of wind receivers - metal strings placed in a magnetic field excited by the source, while self-oscillations occur due to the flow energy, and the strings become electric power generators.

The disadvantage of this generator is its low efficiency, because strings, which are actually semi-coil coils, are not completely washed by the stream due to the fact that the stream is screened by magnetic field sources.

The invention is aimed at increasing the efficiency of the generator by separating the functions of wind reception and energy generation.

This is achieved by the fact that the electrodynamic wind generator contains tail elements and wind receivers made in the form of elastically stretched tapes connected via rods to the spring-loaded movable part of linear electric generators. According to the invention, the tapes are stretched on vertical posts placed on a rotary base of the frame, the tail elements are mounted on horizontal rods attached to the vertical posts, while the tapes are connected to the rods in their middle part.

The invention is illustrated by drawings, in which Fig. 1 shows the inventive wind generator, front view, Fig. 2 is a side view, Fig. 3 is a top view, Fig. 4 schematically shows the attachment point of the linear generator rod to the tape, Fig. 5 schematically shows the average position of the winding of the linear generator, FIG. 6 shows the upper position of the rod, FIG. 7 shows the lower position, FIG. 8 schematically shows the structure of a linear generator with a movable element in the form of a coil, and FIG. 9 shows the structure of a linear generator with a movable element in the form magnet.

The electrodynamic wind generator contains a tower 1, a rotary base 2, a frame 3 with vertical struts 4 is attached to the rotary base, to which horizontal rods 5 are attached with tail elements 6. Bands 7 are tensioned, the middle parts of which are connected via linear rods 8 to linear electric generators 9. Horizontal rods are equipped with struts 10 and a tail bar 11. The place of fastening of the rod 8 to the middle part of the strips 7 can be reinforced with a normalizing bar. The movable part of the linear electric generators is spring-loaded with a spring 12. In FIGS. 5, 6, 7, the movable element of the generator is indicated by 13, the stationary by 14. The first embodiment of the generator has a flexible current supply 15, a coil 16 on the frame 17 connected to the bottom 18, which in turn, it is attached to the rod 8. The fixed stator element includes an internal 19 and an external 20 magnetic cores, a magnetic field source 21 (permanent magnet), a closing magnetic circuit 22, a fixing cylinder 23 and a base 24. The second embodiment, on the contrary, has a movable th magnetic system to the internal magnetic circuit 19, to which the rod 8 is attached. The coil 16 is fixedly mounted on the bracket 25.

Electrodynamic wind generator operates as follows. When the wind flow on the elastically stretched tape 7, they oscillate with a frequency determined by the flow parameters. These oscillations through the rod 9 and rod 8 are transmitted to the movable element of the generator:

- for the first performance - through the bottom 18 with the frame 17 and the coil 16;

- for the second version - through the internal magnetic circuit 19 of the magnetic system, consisting of elements 20, 21, 24. When moving the moving elements relative to the stationary ones, the coil turns intersect by magnetic field lines, as a result of which the emf is induced in the coil, which is then transmitted to the consumer.

The technical and economic advantage of the claimed electrodynamic wind generator is its increased reliability associated with the absence of rotating parts, and low cost, because the active element is elastic bands, which are large-scale products and do not require complex aerodynamic surfaces, the implementation of which is costly.
