The subject of the sample of use is a wind turbine power supply unit which primarily installed on vehicles can store the passage wind and wind power in a chargeable source of power and if necessary an optional external consumer, e.g. the charging unit of a phone can be connected to it.

Beginning from the bicycles up to the different vehicles or even on the smaller watercrafts we can meet some kind of electrical system, e.g. on bicycles the dynamo systems ensuring lighting, however generally these devices are not prepared to charging telecommunication tools or similar, wide-spread personal, portable electronic tools needing frequent charging due to their limited accumulator capacity. The reason for that in most cases is the lack of capacity, or of the internal power storing unit or of the appropriate connection interface. One of the disadvantages of the dynamo lighting systems is for example that they cannot operate as a stable, regulated power source.

In order to gain extra power, in case of a moving vehicle it is possible to make use of the passage wind or wind as a source of power. From the patent data bases there are known descriptions referring to this field, like the Wind Wheel registered under no. 118993, where between the spokes of the bicycle rotatable blades are installed in order to utilize wind power. The Chinese patent no.CN 104454370 (A) - Device for supplementing flywheel battery energy by wind force in bicycle riding patent includes a device installable on the bicycle and storing the power produced by the wind wheel in a flywheel rotatingin vacuum. There is a drive, centrifugal clutch between the wind wheel and the flywheel, which at a certain rotation velocity disconnects the shafts ensuring by that the power loss of the flywheel. In case the consumer needs feed power, it can be provided by a generator fixed to the flywheel and on the account of the stored power. The proposed device is very complicated and for this reason is expensive, as well, furthermore, the blades of the wind motor have large surface, and are vulnerable.

A mobile power source could be the solar cells, as well, but characteristically they are also vulnerable, occupy large area and only under certain weather conditions represent a competitive alternative to the wind power being almost always present in case of vehicles.

Our objective is to provide a device, which can be used in a wide scope and is suitable for the charging portable personal electronic tools, which is simple, not vulnerable and can be easily installed even later.

The invention is based on the recognition that putting the wind turbine into a guiding tube the rotating part of the device becomes protected, furthermore, the external guiding tube makes possible the easy installation, and the guiding tube can be provided with an extended air inlet, if required.

That is, the proposed wind turbine power supply unit consists of a wind turbine and a generator rotating together with it, and where the blades of the turbine rotate in a guiding tube. The guiding tube has an inlet and an outlet opening. A chargeable power source and at least one external connector connects to the generator with the help of inserting a charging power source. In an advantageous form of design of the device, one end of the guiding tube is an extended air inlet.

In a further advantageous form of design of the device the guiding tube is the structural part of the vehicle's tube frame.

The chargeable power source of the device can be a super-capacity or an accumulator.

For the more detailed representation of the sample of use we are using the following figures:

Figure 1 : side semi view - semi section of the wind turbine device installable as individual unit and provided with conical air inlet,

Figure 2: special lower view of the wind turbine power supply unit installable as individual unit,

Figure 3: special view of a wind turbine power supply unit integrated in the bicycle frame,

Figure 4: spatial view of a wind turbine power supply unit located linearly on the roof of a house.

On Figure one you can see the most general design of the device in partially cut view. The main element of the device is the guiding tube (5), which partially controls the air flow before the turbine blades (3), and protects the environment from the rotating parts, and can also include the chargeable power source (7) and the charging circuit (13). Due to the guiding tube (5) the device represents and independent, complex unit being easily installable on different vehicles (e.g.: vessel, bicycle, etc.). The guiding tube (5) is also operable in a different from the shown on the figure arrangement, namely without the conical air inlet (10). The guiding tube (5) - except the part surrounding the turbine blades - can have a non-circular cross-section, as well, in case for example that is favorable from the aspect of fixing. Preferably, the length of the guiding tube (5) is not longer than the ten times its diameter. In the guiding tube (5) a generator (6), on the turbine shaft (12) of which the turbine blades (3) are installed, is fixed by the radial holders (9). The tur bine-generator unit can be installed also so that their shaft is perpendicular to the shaft of the guiding tube (5), and also so that the turbine shaft (12) is connected to the generator (6) through a mechanical transmission located out of the guiding tube (5) in this way not reducing the flow cross section. The design according to Figure 1 is provided with a conical air inlet (10), but it can be used also with air inlet of other form, or bended or slightly conical guiding tube (5) can be used, as well. The conical air inlet (10) increases the collecting surface against the wind flow, and in the guiding tube due to the narrowing cross section the flow rate increases, which in this way is transformed to electrical power by the generator (6) by a higher efficiency. The used air can leave the guiding tube (5) through the outlet openings (8).

On Figure 2 you can see the design being the same as above described from a back spatial view. Purposefully, the chargeable power source (7) and the charging circuit (13) connected to it is located after generator (6) in the end of the guiding tube (5) serving also as a case. The rechargeable power source can be any type of multi-cell chargeable accumulator operating on the known electrochemical principle, or a super-capacity, as well. For a person being skilled in the art, the construction of the charging circuit (13) is evident, and for example in the assortment of Texas Instruments you can find circuits produced for this purpose relating to several different capacities, accumulator types. The device can be provided with different types of external connector (11), however, we primarily recommend the USB connection as the most widespread connection interface. The USB standard makes possible charging by voltage DC 5± V, which in the case of usual accumulators is produced by the serial connection of several accumulator cells,and also has a voltage being appropriate for most of the appliances. In case of demand, the charging circuit (13) can be provided by a connectable outlet voltage, the arrangement of which does not represent a novelty for a person being skilled in this field. It is not against the sample's idea to have an arrangement, where the chargeable power source (7), the charging accumulator (13), the external connector (11) are located not in the guiding tube (or at the end of it), but out of it either surrounding it or even under a separate cover.

A Figure 3 a special application/installation version is represented. As on the bicycles - due to their structural design - there is at least one such frame tube, which closes an angle between 0 and 40 degrees with the movement direction (and the passage wind), where a wind turbine power supply device can be installed in a manner not limiting the usual use at all and in a space saving manner. In the actual case, the generator (6) together with the turbine blades (3) are integrated in the upper tube (4) of the frame, and in this way there is no need for a separate guiding tube 5, but for the effective air introduction it is necessary to have at least one arched air inlet (1) extending from the plane of the frame (4). The arched air inlet (1) directs the passage wind to the inlet opening of the frame (4) located under it. Principally, for the outlet air leaving after the turbine blades (3) the outlet openings (8) shown on the previous figures could be appropriate, but as the frame (4) is also an important load bearing element, as well, this solution should be avoided and instead we recommend to use at least one outlet gill (2). Following the sample, the wind turbine device can be installed in the lower tubes of the bicycle frame, or fixed to appropriate parts of other vehicles, as well, but in these cases, the arched air inlets (1) shall be adjusted to the direction of the expected passage wind.

The Figure 4 refers to a special application field of the wind turbine power supply device. Especially in case of creating a simple guiding tube design, it is possible to install them in groups (serially, in more lines, or in frame). The devices is effective inn case of wind direction depending on the installation direction, but in case of installing more devices the inlet opening of the guiding tubes (5) can look even to more directions. The multiple installation obviously increases the resulting electrical output, as well. The compact design and the small size makes also possible that the wind turbine power supply source is worn by the user itself either on a ski cap or other piece of clothing.

The proposed device meets our specified objective as in an even later easily installable design provides a simple, during movement always available, additional power resource for our mobile telecommunication or entertainment electrical tools.
