Title:
WIND ENERGY CONVERTER COMPRISING ADJUSTABLE SAILS
Document Type and Number:
WIPO Patent Application WO/2008/152431
Kind Code:
A2
Abstract:
The rotating sails are part of a system which consists in one fixed assembly, (2) another assembly that revolves around its fixed counterpart, in contact with the pulleys (3), the sail support base (4), and the sails (5). It also includes the control mechanism (8), the arm (6) as well as the stabilization of the sail at a constant distance (7) from the rotating cylindrical assembly (9), and one system for the transmission of electricity (10).

CLAIMS

, The Rotating Sail, characterized by the fact that it consist in a Fixed Cylindrical Assembly (1), one Movable Assembly (2), which revolves around the Fixed Assembly (1) by means of Pulleys (3). Inside the Movable Assembly (2) there are diametrically opposed fins (5) on Mechanism Support Bases (4). The Mechanism (8). The Movable Arm (5). Each fin is supported on a Fixed Base (7) and on the Movable Arm (6), while the Control Mechanism (8) adjusts the opening of each sail, depending on the direction of the wind and the desirable energy.

Description:

THE ROTATING SAIL

The Rotating Sail is part of a cyclical layout with controlled opening for the conversion of wind power through rotation movement.

Sails have until now been used so that wind power may push the vessel 5 forward while in constant need of adjustment according to the direction of the wind. The sails additionally pose great resistance. The wind power generator and its fins exploit only a minor fraction of the wind and need to be oriented depending on the direction of the wind.

40 The advantage of this device is that it takes advantage of a much greater portion of the wind. By means of the opening of the sails we may adjust the desirable force while there is no need to change the direction.

The rotating sails are in a cylindrical layout while any number of such 45 sails may be installed according to our desires.

Illustration 1 presents the design and its mechanisms. (1) The Fixed Cylindrical Assembly. (2) The Cylindrical Assembly that may revolve around the Fixed Assembly. (3) Pulleys by means of which contact is o20 achieved. (4) The Mechanism Support Base that provides the ability to adjust the opening of the sail. (5) The Fin (Sail). (6) The Arm engaged by the mechanism to move the sail. (7) The point on which the sail is held at a fixed position. (8) The Mechanism by which we may adjust the opening of the sail.

Z5 Illustration 2 shows the appropriate layout and position for the closed system.

Illustration 3 shows the system from a longitudinal point of view in which we can see the supports for the sails and the system of eleςtric 30 power transmission for movement transport (9). Additionally we can see the position preferred for the pick-up and the transport of the rotating movement (10).
