Description

Title of the invention: Modular wind turbine with horizontal axis and reinforced cubic structure. TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to a modular horizontal axis wind turbine, designed to meet current renewable energy needs. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] The transition to renewable energy sources has become a global priority, particularly to address climate challenges and the depletion of fossil fuel resources. Wind turbines play a central role in this transition, capturing wind energy and converting it into clean electricity. This modular horizontal-axis wind turbine offers significant advantages, including its low cost, ease of installation, and ability to integrate seamlessly into diverse environments, such as rural areas, small communities, and remote sites. Thanks to its modular design and automatic orientation system, it adapts effectively to changing wind conditions, thereby maximizing renewable energy production.

[0003] Unlike traditional models, which may require heavy infrastructure and significant logistics for transport and assembly, this wind turbine is easily transportable and can be assembled without heavy equipment. Its installation flexibility makes it particularly suitable for rugged terrain and areas with variable wind conditions, thus maximizing its energy efficiency and practicality in diverse environments.

[0004] This modular wind turbine would reduce transport costs and facilitate on-site assembly, thanks to lighter and standardized components. This design would make it possible to adapt the wind turbine to different usage contexts, from small domestic installations to medium-sized wind farms.

[0005] Current attempts to simplify wind turbines while maintaining their performance do not fully meet these expectations. Existing modular solutions may lack robustness, making them less durable in the face of inclement weather and wind variations. Other models remain expensive or difficult to adapt to specific environments, thus limiting their widespread adoption.

[0006] Furthermore, this invention can utilize recyclable materials, particularly for the manufacture of the blade walls. The use of sustainable materials not only reduces the environmental impact of manufacturing but also enhances the appeal of this wind turbine as an environmentally friendly solution. By integrating Made with recyclable materials in its design, this wind turbine contributes to the circular economy and promotes a more sustainable approach to energy production.

[0007] This wind turbine, with its simple design, can meet users' needs by offering an economical, easy-to-install solution suitable for a wide range of climatic conditions, while contributing to renewable energy production. GENERAL DESCRIPTION OF THE INVENTION

[0008] The present invention therefore aims to provide a modular, easily dismantled wind turbine with a reinforced cubic structure that gives it increased strength while remaining simple to assemble and transport. This would meet users' needs by offering an economical, easy-to-install solution adapted to a wide range of climatic conditions, while also contributing to renewable energy production.

[0009] The wind turbine according to the invention may further comprise one or more of the following characteristics, which may be combined with each other: • Increased Mechanical Robustness: Thanks to the double anchoring point of the blades 1, the stresses are better distributed, increasing durability even in extreme conditions. • Energy Efficiency Optimization: The deflecting wall 3 redirects the wind towards the blades that catch the wind, increasing energy production and reducing efficiency losses. • Ease of Installation and Mobility: The wind turbine does not require permanent foundations, allowing for rapid installation on land or at sea, with the possibility of dismantling and transporting it easily. • Reduced production and maintenance costs: The modular design and cube-shaped structure reduce production costs while minimizing maintenance needs. • Adaptation to Marine Conditions: Thanks to the floating anchor and the ability to pivot in the face of wind and waves, the wind turbine is particularly suited to offshore installations. • The wind turbine automatically orients itself to face the wind. Mounted on wheels, it pivots around a vertical axis of rotation. At the rear, panels create wind resistance, generating a force that rotates the turbine until it is aligned with the wind, thus optimizing energy production without requiring a motorized system.

[0019] DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

[0020] The modular horizontal axis wind turbine according to the invention is distinguished by a reinforced mechanical structure and an innovative system for protecting the blades rising up against the wind.

[0021] The rotating shaft of the blades 1 is fixed at two anchor points located at its ends, ensuring a uniform distribution of mechanical stresses. These anchor points are securely connected to a cube-shaped structure 2, providing greater stability, particularly in strong winds. This configuration reduces the risk of premature wear and improves the durability of the wind turbine.

[0022] The blades 1 have a large surface area, which makes it possible to increase the energy recovery capacity even at low wind speeds.

[0023] An innovative deflector wall system 3 is positioned near the blades 1 at a 45° angle to the ground. This device redirects the airflow towards the descending blades, thus maximizing energy efficiency. Simultaneously, it protects the upward-moving blades 1 against the wind, reducing drag and optimizing rotor rotation.

[0024] The wind turbine is mounted on a structure capable of automatically pivoting along the wind axis 5 thanks to an integrated wind vane system 4. This ensures optimal positioning to capture the maximum energy, regardless of variations in wind direction.

[0025] The wind turbine structure is designed for easy installation without permanent ground anchoring, making it ideal for temporary installations or in harsh environments, such as marine areas. It can be moved and installed quickly, thus improving its operational flexibility. At sea, it can be held in place by an anchor, while allowing for optimal orientation in the face of wind and waves.
