DESCRIPTION OF THE INVENTION
The present invention relates to a wind energy conversion system with automatic protection. The invention is obvious innovation in the field of energy production based on natural energy without pollution and provides an ideal operation of the drive, eliminating the risks associated with damage to or failure of machinery. This is achieved by an integrated protective devices, the advantage of which is that in the event of high winds, thunderstorms and storms automatic means drive mechanisms based sensors and other automation elements include a safety device, which in turn by a drive motor or otherwise alters the direction of rotation rotating the entire unit, causing coagulation and folding blades or elements having a triangular sail shape, causing wind turbine stops. Features and design elements that make up the installation, significantly different from those of any of the currently known wind turbines. This fact, as well, and novelty and practical value of the invention provide a reasonable basis for the provision of the right holder, according to his application, the exclusive rights to manufacture and sell the described installation in Spain by virtue of this registration of patents for inventions.
technique described above provides for the existence of different wind turbines equipped with, as a rule, in the form of rotating blades mill wheel. There are also models with blades resulting in movement of a horizontal shaft in the form of blades different in number and shape, and a plate-based mechanisms, resulting in movement of the vertical axis in the form of spiral vanes, turbine, or any other sleeves. All existing systems have a number of disadvantages associated with the frequent failure of and damage due to lack of protective devices.
The invention is to provide a wind energy conversion system in which the above drawbacks would be absent.
The problem is solved in that the energy conversion system of the wind with automatic protection according to the invention comprises a vertical positioning shaft on which is rotatably mounted a core with several equidistant sleeves, inside which, forming part of the central rotating block shaft extends, on both of which the ends are bevel gears which are connected with a bevel gear with half the number of teeth which constitute part of the vertical positioning of the shaft on the other hand, on opposite ends of the sleeves bevel gears connected with exactly the same bevel gears located on the vertical shaft mounted in bearings , and in the upper part of the vertical shafts is provided a ball joint or a hinge for connection with the upper inclined portions rising cantilevered shafts serving as a support and guide for the folding blade, driven by the wind.
Preferably, the claimed system of the wind energy conversion comprises a bearing and a cruciform yoke arranged on the inclined upper arm portion ascending shafts connected with bushings at both ends traverse are pulleys, which by a flexible and resilient connection are connected to the bottom corners of the triangular blades separated into two part on both sides support their ascending shaft, said blades are affected by the wind, are configured coagulation sails and are mounted on the ascending shaft by means of equidistant elastic ropes along the entire height, allowing the blades to fold into the shape of sails on the ascending shaft in the event that due sensors or other electronic or mechanical means a change in direction of rotation of the block.
Equally preferably, the vertical positioning shaft extends uplink through mechanisms center of the unit, and in its upper part, the shaft ends round guide disc, which peripherally on the bottom plane or bottom mounted by means of ball joints the upper end of the ascending shaft supporting the blade in the form of sails driven by the wind, they provide a uniform movement in the guide disc are mechanisms by which the entire mechanism when changing unit rotation clotting occurs blades shaped triangular sail, causing the blades cease to operate and blocked.
The claimed system enables the wind power conversion to overcome these drawbacks, since its construction is based on the entire block is rotated around the central shaft, fitted at the top plane of rotation of peripherally distributed ascending shafts on which are fixed on both sides of double triangular blade. Triangular blade fold on their poles like sails. It occurs when the block starts to rotate in the opposite direction when stormy gusts, during a storm or other adverse circumstances, the reverse movement is provided automatically by means of sensors and other components, thus avoiding damage to or failure of a wind energy conversion system mechanisms.
This energy conversion system of wind with automatic protection has a vertical central shaft, on which the axis is mounted rotating unit mechanisms, which in turn in several peripheral points attached triangular blade, consisting each of two halves attached to the rising stem or support that in the upper part are movable around the central shaft in the correct direction, while the reverse is rotatable itself upward rod on which are fixed double triangular blade so that the blades are twisted around a rod in the form of sails, allowing thus avoiding a sharp gust of wind exposure. Thus each rod upward or support on which the blades are fixed, in its lower part has a drive through a bevel gear transmitting rotation of the core of the central unit with the rotor equipped with the transmission, converts the movement into energy.
Triangular shaped blade sails, in its lower part, the cables have to ensure their securing to small pulleys at both ends of a traverse connected with the free bearing supports upward. Mounted on these springs or other resilient members provide tensile folding blades and their subsequent deployment. Passing through the pulleys, ropes held against possible displacement by special guides.
All conical toothed gear wheel are identical, i.e. have the same number of teeth, while the central bevel gear coaxial with the lower vertical shaft has teeth exactly two times smaller than the bevel gear wheels on vertical shafts by the edges of the transmission hub.
Vertical shafts, representing the lower part of the console supports folding blade with bevel gears and corresponding swivels coaxially connected to cross-members supporting the bottom folding blade. The whole unit is connected via bearings to the upper parts of the supports cantilever double triangular blades. Upper closure arm portions supports by means of ball joints are fixed to the upper disk of the central shaft, in which they are inserted through small vertical shaft. In gusty wind conditions or adverse weather unit provides drive rotation direction of draw, while the lower rotating central core fixed by bearings on a fixed support fixed to the ground.
For a better understanding of the above general characteristics of the device attached drawings illustrating, in schematic form, one of the possible cases of operation of the wind energy conversion system with automatic protection. It is necessary to note, that the drawings have exclusively informative role. Depicted on these figures should be viewed as a generalization. No restrictive features to claim they do not have.
