Details

Tittle:
Rotation device of a wind turbine blade on its longitudinal axis.
Summary:
A Basque SME specializing in the design and development of customized servo actuators and servo systems, has developed an innovative device rotating blades of wind turbines, which obtains a better performance. The company is looking for companies all around the world interested in licensing its patent or establishing joint collaborations for the exploitation of the technology.
Description:
A Basque SME involved in designing of customized systems to generate clear energy has developed a device rotating blades of wind turbines which produces energy more efficiently.
The inclination angle of the blade of a wind turbine is controlled by the pitch control. This closed-loop control can be electric or hydraulic.In case of a hydraulic solution, this can be solved using one or more hydraulic motors with pinions or installing a linear actuator. In this case it is necessary to convert linear motion into rotational.
This hydraulic invention generates rotational movement without conversion, using a single toroidal chamber which is concentric to the axis of the blade. Its circular shape allows it to integrate with the bearing.
In a single toroidal chamber, several pistons with the same number of stroke stops coexist. For a maximum of 90 degrees, the chamber can be mounted to a maximum of three pistons and three stops.
Inside the toroidal chamber, pistons are in solidarity with the blade, and the stroke stops with the fixed part.
The company looks for companies all around the world interested in licensing its patent or joint collaborations for the exploitation of the technology.
The Basque SME can help the partner with technical assistance and tailor made solutions.
Advantages and Innovations:
The rotation device of the invention presents the same advantages of other hydraulic systems to prevent emergency situations, storing energy in a hydraulic accumulator.
Its circular configuration allows better integration with the side bearing and the fact of not having a single point of support avoid the generation of unwanted torques.
Concentric sealing system requires less maintenance.
Hydraulic area ratio is 1:1.
The hydraulic system can be powered by a conventional hydraulic group with rotational ring and a servo valve, or can also work in closed circuit, using a fixed pump coupled to a reversible and variable motor. In this case the system needs a small pressurized tank, as well as an accumulator, to recover the drains, but does not generate heat because the servo valve does not exist.
The hydraulic system with these advantages, becomes an autonomous electrical system.
This technology is also interesting because it reduces maintenance needs, which are critical in offshore applications.
The system can help to improve the design of the pitch control, simplifying the number of systems involved. It is possible to convert the bearing and actuator in a single element: Automotive bearing.

One of the most important innovation of this hydraulic actuator is composed of two half bodies, which generate a toroidal space where the pistons move in an arc between the two stroke stops. This toroidal actuator is circular, and may stay inside the space of the bearing. There is no need to convert linear motion to rotational. The sealing system is concentric and highly wear resistant for low maintenance.
The bearing and the actuator can be mounted in a single package because both require a fixed supporting surface and generate a moving surface.
Power is transmitted uniformly across the diameter of the bearing, without generating unwanted pairs, extending the life of the product.
