Description

The present invention relates to unconventional energy sources and can be applied in installations using wind energy, river, deep sea and other currents.

Known devices that convert the kinetic energy of wind into electrical energy (see ed. Certificate. No. 1020622, bull. No. 36, 1983, No. 1116307, bull. No. 36, 1984, No. 1423777, bull., No. 34, 1988, French patent No. 2704908 and others).

Known devices that convert the energy of sea waves, tides (see ed. Certificate. No. 1097819 and others).

The listed devices are not universal, bulky, require orientation in the stream and are not always environmentally friendly.

These disadvantages are to some extent excluded in the device (see patent No. 2141576). The water-wind power installation contains a vertical shaft with rods perpendicularly mounted and diametrically arranged at equal angles with blades and a device for orienting the energy flow of a moving medium, characterized in that the blades of each pair are mounted through hinges along the rods with the possibility of their joint opening from one to the other from 0 to 180 ° by means of rods limited by spherical hinges connected to sliders placed on the rods, and through forks contact end faces tyami through bearings eccentrically fixed to a vertical shaft cylinder device orientation.

The disadvantages of this device:

design complexity;

the need for orientation in the direction of flow;

The objective of the invention is the creation of a simple, environmentally friendly device, non-critical to the direction of flow, working in both liquid and gaseous environments, as well as in the separation of media.

A device is proposed comprising vertical shafts and horizontal rods with blades, characterized in that the rods are through and mounted on the shafts with the possibility of limited rotation relative to their axes, the opposite blades of each rod are rigidly fixed thereon perpendicular to each other and eccentric relative to the axis of the rod, while horizontally adjacent shafts are made for rotation in opposite directions.

Figure 1-3 shows a diagram explaining the operation of the device.

Figure 1 presents a diagram of a device (module of minimal complexity) with one shaft, two rods and vanes of the upper location. The device contains a vertical shaft 1, on which rods 2 with blades 3, and limiters of rotations of the rods 4 are mounted. This design allows manufacturing devices with rotation of the blades both up and down relative to the axis of the rod, including the installation of rods in pairs-vertically with multidirectional rotation of the blades; devices of both right and left rotation, as well as assemble installations of any power from standardized modules.

To work on the media section, one horizontal row of rods with blades of lower location is used (Fig. 2, the same notation).

With a constant flow direction or alternately multidirectional flow (high-tide), a dam is built (Fig. 3) from identical counter-rotating modules. Non-working sectors of the installation can be closed by hubs, directing additional flow to the working sectors.

The device operates as follows. In the static position (without load), the rods 2 with the blades 3 occupy an arbitrary position relative to the axes of the rods within the limits established by the limiters of the rotations of the rods 4. When the gas or liquid flows in motion, the rods 2 together with the blades 3 are turned relative to their axes to the limiters 4 so that the blades each rod located on different sides of the shaft 1 relative to the direction of flow, are installed one parallel, the other perpendicular to the flow. The direction of rotation of the rods with blades relative to their axes, as well as the direction of rotation of the shafts are set by the positions of the limiters of rotation of the rods (see figure 1, figure 2). As a result, a torque moment proportional to the sum of the moments of its rods acts on each vertical shaft.

When the shaft rotates and the rod rotation angles go through 0 ° and 180 ° relative to the direction of flow under the influence of medium resistance and flow pressure, the blades together with the rods rotate 90 ° relative to the axis of the rods and change their position, the blade parallel to the flow occupies a position perpendicular to it, and perpendicular - parallel. As a result, the direction of action of the torque on the shaft does not change, that is, the installation does not require orientation in the direction of flow.

The device easily starts at a minimum wind speed, especially at the upper position of the blades, and works with a wider range of flow rates, since the speed of the blade is less than the speed of the stream.

Due to the eccentric installation of the blades, dynamic loads are smoothed out when turning the rods.

The multidirectional rotation of the shafts of the horizontally adjacent modules smoothes the vibrations and reduces the loads on the structures of the multi-module installation.

In comparison with the known, the proposed device has the following advantages:

- can work in both liquid and gaseous media, as well as in the separation of media without orientation in the direction of flow;

- allows you to collect installations of any power from standardized modules;

- environmentally friendly due to the noise factor, since the speed of movement of the blades is less than the flow rate.
