Description

Description of the invention

The invention relates to the field of power mechanisms, namely, wind and water engines, and can be used to drive a fan when ventilating a room, a pump when pumping liquid, but this invention has the main value in the field of electric power engineering when working with an electric generator as a load device connected with the lead element of the installation, for example, an asterisk.

The wind power installation contains a base, a bearing housing rigidly seated on it, in which a shaft sits on the bearings, in the grooves of which there are blades limited by stops, in the amount of two or more, and they are located at different heights and with an angular displacement, namely when the number of two pieces at an angle of 90 °, and the blades can be round. On the uprights, rigidly sitting on the bottom cross, are installed inclined platforms, with the possibility of regulation, through which the shaft passes. Platforms opposite the wind are installed with the help of a weather vane, rigidly sitting on a hub, which is free to sit on the shaft, but is rigidly connected by racks. Blades on inclined platforms descend under the action of their own weight and the weight of special loads in the form of balls or mercury located in pipes located in the lower parts of the blades, remaining in the grooves of the shaft, and fixed with latches. With further rotation of the shaft of the blade, being established perpendicular to the wind or the flow of water, working in a part of the trajectory like a sail, create the maximum torque. The blades, remaining in the grooves of the shaft, at the same time rise on inclined platforms upwards and not reaching the top point (180 °) are unlocked and tend downwards, being in the shaft grooves. Torque created by the blades is transmitted using a rigidly mounted shaft, for example, sprockets and chain transmission, and a driven sprocket causes the rotational movement of the load device, for example, a generator to generate electrical energy, and the asterisk on the shaft is made massive for pulsation. To reduce the friction force of the blades on the platform, they are equipped with wheels.

Several options have been developed for reducing the friction force when lifting on an inclined platform; an option is provided with an axis mounted along the ends of the blades on bearings rolling along the anchor-guide, reducing the effort of raising the blade along an inclined surface.

To reduce the lifting force of the blades, there is a gap between the platform and the blade, the optimality of which is determined by experiment.

In order to reduce the time of descent of the blades, a variant of installation with a round-shaped blade with fixation in a similar way was proposed, namely, on the underside of the platform, a housing was mounted coaxially on the shaft with a disk on which a cam and a roller with a lever were installed for adjustment rectangular blades and roller with a rod for round blades unlock retainers at the right time.

Hydraulic power plant GSU can work on water, under water and under ice, to maintain the installation at a certain depth, pontoons are provided, and at a certain place piles or anchors and attached with chains.

Wind power plants can work in the bush method on one plate two or more wind power plants and in one place two or more hydro power plants under water, and at the top two or more wind power plants.

When used in one place two or more installations allows you to generate a large amount of electricity in one place.

At the location of the pipe for additional cargo on the lower part of the blades, the grooves on the shaft are made wider, allowing the passage of the blades.

Guides are provided for the stability of the blades.

For cases where the wind often changes direction, a damper mounted on the base is provided, and a damper cover is installed on the bottom crosspiece; with the help of a latch, the stand brakes with platforms can be stopped in any position. By varying the angle of inclination of the platforms and additional weights, the greatest effect can be achieved.

For better sail, the blades may be loosely covered, for example, with a fabric material.

The blades can be placed not only in the groove, passing through the shaft axis, but also in the pockets on the sides (not shown).

Installation is made collapsible in order to facilitate transportation.

Due to the absence of a non-operating phase, the efficiency of using wind energy or water flow increases.

Wind Power Plant

Technical field

The invention relates to the field of power mechanisms, namely to wind and water engines and can be used to drive a fan when ventilating a room, a pump when pumping liquids, but this invention has the main value in the field of electric power engineering when working with an electric generator as a loading device connected installation element, for example, an asterisk.

The VGSU hydro-power installation can be used both for the conversion of wind energy and for the conversion of the energy of water from rivers, seas, outgoing water after hydroelectric turbines, where there is only movement of water. Wind power plant, in principle, the same plant, can be used as a wind power plant to convert wind energy and hydro power GSU to convert water energy depending on where it is installed, in water or on the surface.

The author does not know the sources of scientific, technical and patent information containing information about similar technical solutions, there are signs similar to the characteristic that distinguish the claimed solution from the prototype, as well as properties that coincide with the properties of the claimed solution, therefore we can assume that it has significant differences , allowing in practical implementation to create new powerful and easy-to-operate wind-power plants.

The prototype for this solution is selected RF patent RU 2587731 C2, 06.26.2014.

The disadvantage of the wind-power installation of this patent is the complexity of the design and a large interval of the non-working phase.

The main difference of the proposed invention from the prototype is that the proposed design of one blade works for two, since there is almost no non-working phase, the prototype four blades create maximum torque every 90 °, and the proposed design has two blades, resulting in increased efficiency wind power or water flow.
