SK9725Y1 - Multi-rotor wind energy system - Google Patents

Abstract

The multi-rotor wind energy system is suitable for hard-to-reach places such as higher mountains, deep seas, roofs. The fundamental of the technical solution is the concentration of the flow through a terrain, a construction or a suction turbine (4), which with its blades on an axle (3) below and above a front beam (7) and the discharge speed sucks the surrounding air flow and thereby accelerates it at the point of wind capture with a multi-rotor system. The rotors (6) are on the axles (12) and they are mounted in parallel on the crossbars of a rear beam (11). The direction of buoyancy forces and the axles (12) is the same as the anchor ropes (14). The pole (13) is loaded only in the spring mode by the weight of the device, which is reduced.

Description

The field of technology

The technical solution concerns multi-rotor wind-energy systems with an increase in economic efficiency and with a power booster intended mainly for hard-to-reach places, mountains, seas and in micro categories for roofs.

Current state of the art

At the moment, mainly single-rotor three-bladed systems are developed using terrains available on land, coastal systems with relatively shallow water depth in the sea. Wind turbines are grouped into wind parks, or farms and the produced electrical energy is processed in the center of the farm and transported over long distances in the form of a high-voltage direct current line. High-quality mountain wind is rarely used in higher mountains due to the difficult accessibility and high weight of all components. Similarly, coastal systems are limited by depth and distance from shore. Current offshore wind energy systems are expensive to produce hydrogen and transport it.

The essence of the technical solution

The higher efficiency of the production of green electricity is made possible by a technical solution, the essence of which is the location of the intake turbine on the front beam. The intake turbine is composed of axially aligned rotors on the axis of the intake turbine and stator surfaces to maintain axial flow, which is driven by a central wind turbine that is mounted centrally above the rear beam on the stator surfaces. Around it is at least a pair of axles with rotors located on the crossbars of the rear beam with an inclination specifically chosen for the given terrain. The axes are terminated by generators at the bottom. The front beam and the rear beam are rotatable in the direction of the wind on the vertical axis, the transverse horizontal axis allows the system to be folded into a safe position. The partitions on the beams are reinforced with ropes from the column above the column, which is reinforced with anchor ropes with anchors on the ground.

In a marine application, the system includes ship screws on an extended centerline below sea level, which relieve the tension of the lashing lines or allow the system to sail.

Implementation examples

The mountain multi-rotor wind-energy system for the use of hard-to-reach locations with the possibility of gathering accelerated flow on the top or ridge enables the low weight of all components. The beams have reinforcements with ropes 16 from the column 17 of the front beam 7 and the rear beam 11. j. about 20 times, without the need for a gearbox, without the need for foundations and a tower, given that the resultant of the buoyant forces coincides with the direction of the anchor ropes 14 attached to the anchors 15, so that the column 13 is short and low-mass. The suction turbine 4 with the stator surfaces 8 are light high-speed devices with centrifugally stabilized blades. The ascent of the mountain flow from the intake turbine 4 driven by the axis 12 of the central multi-rotor turbine makes it possible to harmonize the angle of the anchor ropes 14 with the resulting direction of the load of the system in the direction of the axes 12, which is the driven axis 3 of the intake turbine. The generators 10 are gearless, steering with the rudder 9 on the axis 18 and tilting the system on the horizontal axis in excessive wind to the leeward position are activities that do not require expensive and weight-bearing servomotors, including their reduction gears. The low specific weight of all components will allow construction anywhere in the field or on buildings in urban areas without the need to build an access road.

On a peak with a steep climb, it is effective to use a system with a suction turbine 4, and in this way to concentrate even the bypass flow in the collection areas of the wind wall. The system makes it possible to simplify periodic hot air defrosting by short-term electric heating in the intake turbine 4.

Another version is a marine multi-rotor wind energy system.

The wind energy system will use the low weight of all components to reduce the weight and cost of the floats, which can be under the column 13, while the mooring lines 14 with anchors 15 are anchored on the bottom or on a floating structure, connected to the net for the whole farm, anchored to the bottom only in three points. The farm can be used for the electrolytic production of hydrogen and transported to the coast through a deep pipeline. Water pressure and gas pressure will make it possible to dimension the pipeline to a lower excess pressure. Autonomous floating systems can be operated 10 by the thrust of ship propellers 1 driven by a central multi-rotor turbine in deep sea hydrogen production.
