Abstract

Usage: in wind energy, in particular in wind turbines with a vertical axis of rotation. SUBSTANCE: wind flow is concentrated by canvases and directed to wind wheels located on a platform. The wind wheels are connected to a generator that supplies the consumer with energy. 1 C.p. f-ls, 3 ill.

Description

The invention relates to means for producing environmentally friendly cheap electricity using wind energy. The wind turbine can be used in the field by geologists, hunters, reindeer herders, shepherds, tourists, etc. When folded, the wind turbine (wind to) can be placed in a backpack (up to 0.5 kW), in the trunk of a passenger car (up to 3 kW) and other vehicles. Using a quick-mounted wind turbine, you can heat and light a tent, cook food, etc.

The purpose of the invention is to increase power.

In FIG. 1 shows a general view of a wind turbine from the direction of the wind; in FIG. 2 is a view along arrow A in FIG. 1; in FIG. 3 is a section BB in FIG. 1.

The wind turbine consists of a mast, a platform assembly 1 and paintings made of film or other elastic material.

The mast consists of two separate parts: upper and lower. The upper axis 2 of the platform is held in the upper part, the lower axis 3 of the platform is held in the lower part,

The upper part of the mast is made in the form of a pyramidal beam, in which the height is a tubular rod 4, horizontal rods 5-7 are made of rigid material, for example, a pipe, corners, plates, etc., and the ribs 8-13 of the pyramid are made of flexible elastic cord.

Hinges are made on horizontal rods x 18. All this ensures quick folding of the upper beam into a compact inoperative position (no more than 10 s).

In order to increase the power of the electric motor, the horizontal rods are elongated. And between the elongated elements of these rods and the lower part of the mast, the canvases 14 are stretched, which serve as additional shield-wind traps. The webs are further attached to the slings 15.

Each web below is stretched by stretch marks, one of which is attached to the stake 16, driven into the ground, and the other to the central tubular support 17. In case of a change in the direction of the wind, it is enough to transfer the location of the stakes.

Hinges 18 are made on horizontal rods of the beam to quickly and compactly fold them to the off position. The horizontal rods may be in the form of a retractable tubular antenna, or of plates folding according to the principle of a folding meter or the like.

The canvases 14 are fastened at the top, for the horizontal rods of the traverse, on the sides - for the slings 15, and from below - for the support 17 using a cord 19,

The wind farm is assembled, for example, taken out of a backpack and an assembled platform is assembled from the elements. The top of the mast is disclosed — a pyramidal traverse to the working position. A platform 1 with a lower axis is mounted in a tubular part 17 which is driven into the ground.

The upper part of the mast (pyramidal traverse) is put on the upper axis of the platform and the entire wind turbine with the help of stakes 16, sling extensions 15 is set in working position. If necessary, increase the power installed canvas - wind traps 14.

The wind flow deviating from the canvas-wind traps is concentratedly directed to the blades of the platform’s wind wheels 20 and the wind turbine generates electricity.

Dismantling and folding for transportation in reverse order, for example, to fold the beam, you need to pull out the ring 16 and untie the cords 19, i.e. folding time, for example, in a backpack, no more than 1-3 min.

FORMULA AND Z.O.BRETEN

Claims (2)

1. A wind turbine containing load-bearing elements with wind wheels located on the mast, reinforced with braces and made in the form of an axis, and the upper pyramidal part with traverses, one of which is located vertically along the height of the pyramid, and the other are connected with it, placed radially in horizontal planes and have a length greater than the radius of the wind wheels, and flexible rods connected with traverses and located on the side faces of the pyramid, characterized in that, in order to increase power, the wind turbine is equipped with at least two blades and fixed to the radial cross-arms, bonded to the stretch and the bottom portion zhkami axis and arranged in vertical planes. 2. The wind turbine according to claim 1, with the exception that in order to increase the convenience of operation, the axis is made in the form of a pipe, and the radial traverses are provided with hinges. 1 P fifteen 1 Type A 5 - 6 ft Shig.Z
