Definitions

• the present invention relates to the wind generator with vertical rotation axis, in particular for mobile applications designed for generation of electric, mechanical or other form of energy.
• Pair of arms in the RU2364748 C1 patent is connected on the side of working blade with one console, on which there is working blade attached in rotary manner.
• Change of blades rotation diameter and therefore also volume of the generator is done by mechanism with geared segment placed on the arm in the part of rotating shaft.
• the wind generator with vertical rotation axis in particular for mobile applications, consisting of at least two blades, which are attached on the central shaft by means of fixing set of elements, according to the present invention
• the substance whereof resides in that the fixing set of elements is constructed as shifting mechanism for continuous change of the distance between blades and the shaft, and thereby also for regulation of the generator’s power output in the working position during rotation of blades, as well as for reducing its volume at change of working position to transport one during stagnation of blades, while longitudinal axis of each blade is parallel with longitudinal axis of the shaft.
• Sliding mechanism consists of arms mutually interconnected by joints, draw-bars and servo-mechanism.
• At least two arms are connected by joints to each blade, and at least one draw-bar connected with servo-mechanism is attached on least one of arms.
• the servo-mechanism serves for adjusting the angle between shaft longitudinal axis and the arm and thereby also for change of the distance between blades and the shaft.
• Each of blades is advantageously connected with the arm by means of outer joint, the bearing surface whereof is structurally arranged according to the blade profile.
• the arm is advantageously connected with the shaft by means of internal joint, which is provided as part of the shaft.
• the servo-mechanism is interconnected with control unit, which is connected to driven device and/or its revolutions sensor.
• the advantage of mentioned design is that simple construction of shifting fixing mechanism of blades is used for regulation of the generator’s power output as well as for reducing its volume at change of working position to transport one.
• FIG 1 shows basic construction of the wind generator in working position
• FIG. 2 shows the wind generator in the conditions with maximum distance of blades from the shaft
• FIG. 3 shows the wind generator in the conditions with reduced distance of blades from the shaft
• FIG. 4 shows the wind generator in the conditions with minimum distance of blades from the shaft
• FIG. 5 shows the wind generator in transport position
• the fixing set 1 of elements consists of arms 5 mutually interconnected by joints, draw-bars 8 and servo-mechanism 9 .
• Joint mechanisms each with three inner joints 6 , which are arranged in the shape of “Y” letter and mutually symmetrically shifter by 120°, are provided in the upper part of the shaft 2 in two planes (upper and lower).
• One arm 5 is attached to each inner joint 6 , and there are six arms in total.
• the control unit 13 sends the signal to the servo-mechanism 9 for shifting draw-bars 8 in the upward direction, what turns arms 5 so that the angle a increases. Thereby the distance L is increased, what causes increase of the generator’s power output, whereby revolutions of the shaft 2 increase.
• the blade longitudinal axis 10 remains parallel with the shaft longitudinal axis 11 in any distance L and any angle a .
• draw-bars 8 When transport of the generator ( Figure 4, Figure 5) is needed, draw-bars 8 are shifted by the servo-mechanism 9 downwards to the lowest position. Thereby arms 5 are turned in such manner that the angle a equals to zero and the distance L between blades 3 and the shaft 2 remains minimum. Thereby minimum total volume of the generator for easier transport is achieved. For re-activation of the generator, draw-bars 8 are shifted upwards for increasing its volume.
