Description

The present invention relates to wind power generation systems. More specifically, the present invention relates to wind power generation systems for generating electricity in high wind environments.

Modern society is becoming more aware than ever of the need to increase its dependence on clean, renewable energy sources. One highly efficient clean energy source is wind power, but currently mankind's way of harvesting energy from the wind is inefficient. Since most of the wind power generators are installed in stationary places where the airflow is not constant and the wind blows from multiple directions, a large-scale facility is required to obtain a relatively small amount of power. Such installations are expensive, occupy land that could be used for other purposes, and can spoil the view of the sea if installed offshore.

<First Embodiment>

FIG. 1 is a perspective view of a wind power generation system attached to the roof of an automobile according to an embodiment. FIG. 2 is a side view of the wind power generation system attached to the roof of the automobile according to the embodiment. FIG. 3 is a plan view of the wind power generation system attached to the roof of the automobile according to the embodiment. In FIGS. 1 to 3, the exterior of the housing is removed for clarity of explanation.

1-3, exemplary configurations of a wind power system 100 mounted on the roof of an automobile 200 are shown from various angles. Much of the exterior of housing 102 is shown removed for clarity. In fact, the entire assembly may be covered and resemble a cargo cabin.

The structure of the housing 102 itself is the basis of the wind power system, and exemplary structures are shown in more detail in Figures 4-9. 4-9, housing 102 has a front inlet 122 and a rear outlet 124 oriented to face a first direction. It can be seen that these openings together form an airflow path in which the winged turbine assembly 106 is positioned. The axis of rotation of the winged turbine assembly 106 is perpendicular to the direction of incoming air flow. That is, the axis of rotation of the winged turbine assembly 106 is perpendicular to the direction in which the opening faces (the first direction). For example, in FIGS. 1-3, the wind power system 100 is placed on a vehicle with the front inlet 122 facing forward so that air is forced into the front inlet 122 as the vehicle moves forward.

Housing 102 may consist of a base and a shell. The base and shell may form a locking mechanism. Alternatively and/or additionally, the shell may be hinged to allow easy access to the battery for cleaning and/or repair. The base may be made from aluminum, stainless steel, cast iron, zinc alloys, chrome, hardened plastics, thermoplastics, polyurethanes, polycarbonates, polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride, etc. and/or combinations thereof.

The opening of front inlet 122 may be rectangular, oval, or have rounded corners. The opening may be closed and/or locked to prevent ingress of water and/or dust. The opening may include flaps to direct air into the opening and prevent air from flowing under the bottom of the housing. A flap may be used to close the opening. The shell may be made from hardened plastics, acrylonitrile butadiene styrene, polycarbonate, thermoplastics, polyurethane, polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride, or other waterproof or water-resistant plastics, etc. and/or combinations thereof. good.

As shown in FIG. 9, the blades 128 of the turbine, which in this example are curved and centered about the shaft 126, occupy most if not all of the width of the front inlet 122 so that the inflowing All of the air pressure from the air is applied to rotate the turbine.

Since the air passes through the turbine and out the rear outlet 124, this does not significantly affect the aerodynamics of the vehicle. Shaft 126 is secured within winged turbine assembly 106 via fixture 120 .

Other arrangements of turbine blades are possible, but they must take advantage of the directional high velocity airflow in the required manner. For example, the turbine may be a kinetic turbine, a propeller turbine, a Savonius turbine, a Darrieus turbine, a Kaplan turbine, a Giromill, or the like.

1-3, the winged turbine assembly 106 is positioned toward the front of a housing 102 that is secured to the roof of the vehicle 200 via various attachments 104 . Winged turbine assembly 106 is connected to generator 108 via coupling assembly 110 . In this embodiment, the connection is made by two pulleys, a first pulley 118 rotatably coupled to the winged turbine assembly 106 and a second pulley rotatably coupled to the rotor of the generator 108. is taking

These first pulley 118 and second pulley are in turn connected by a belt, in this example by a reductor. This reduces the rotation of the torque load on the winged turbine assembly 106 and allows the turbine to maintain rotation even at low wind speeds rather than being dragged down by the torque load from the coupling with the generator 108. to This reduces the surface area of the winged turbine assembly 106 from interfering with the headwind aerodynamic characteristics of the vehicle. A flywheel may also be used as part of the winged turbine assembly 106 to maintain rotation when airflow is low, such as when the vehicle is momentarily stopped, slowed, or cornering. .

As seen in both FIGS. 1-3 and 4-9, the housing 102 has an airflow barrier 116 positioned in front of the front inlet 122 to direct additional airflow to the winged turbine assembly 106. . Also, the airflow barrier 116 is configured to prevent air from flowing under the turbine assembly. Airflow barrier 116 may be coupled to housing 102 via a hinged joint that may double as a cover for front inlet 122 . The airflow barrier 116 has the secondary function of preventing airflow from causing reverse rotation of the turbine blades.

The power generated using the arrangements described above and variations thereof are used in a variety of applications. It can power vehicle functions both during and between transports. In some cases, a direct connection to the vehicle battery is also possible. In fact, instead of being separate from the vehicle, the generator 108 may be the vehicle's alternator, in which case it can produce the same output voltage at different input speeds. It can also be connected to a generator with a gear assembly that allows the same output speed to be derived from a variable input speed.

Referring to Figures 10 and 11, an example of a turbine system located under the front hood of an automobile is shown. This arrangement is particularly suitable for electric vehicles where this space is available. This allows the battery to be partially charged while driving and can also be used for auxiliary functions such as air conditioning (AC), thus extending the range of the vehicle.

In some examples, when the turbine system is placed in the front of an automobile or watercraft as shown in FIGS. 10 and 11, it is the wind flowing under the assembly that causes the turbine blades to rotate. , the assembly can be placed. That is, the direction of rotation would be reversed with respect to other configurations described in this embodiment to allow for airflow coming from below rather than above. The same aerodynamic principles discussed for other configurations apply to this alternative configuration.

The turbine can also be used in some instances as a mechanical amplifier for an already rotating vehicle shaft, increasing the speed of the vehicle's wheels when installed under the hood of the vehicle.

Returning to FIGS. 1 to 3, description will be made. In this embodiment, the power from the generator 108 is stored in a secondary battery pack 112 connected to the generator via an inverter, and the stored power is accessed through a power socket 114 on the side of the system. is also possible. As a result, electric power can be supplied to various electrical appliances, for example, between transfers during long-distance travel. The top of housing 102 may be removable to access power socket 114, and the entire assembly may be removable from the roof of the vehicle.

The power socket 114 may have a lockable cover to protect it from water, dirt, and/or dust, and may include one or more EV charger female type 2, EU socket, US socket, USB socket, or Additional sockets and/or ports may be included.

By connecting to the socket panel that outputs power, various devices can be charged and powered by battery power banks, such as vehicles, laptop computers, smartphones, electric razors, portable stoves, electric kettles, air pumps, heaters, fans, etc. /or may be powered.

The wind power generation system 100 may be directly attached to the vehicle or assembled to a rack attached to the vehicle. The wind power system 100 may be mounted flush with the vehicle and/or on non-slip guards to prevent scratches and/or on systems including racks and/or crossbars and legs and/or beams, e.g. It can be installed in roof rack systems for vehicles with or without.
As described above, the wind power generation system 100 is not limited to being mounted on an automobile, and can be mounted on or integrated with a wide variety of other vehicles and ships.
12 and 13, the wind power generation system 100 installed on the roof of a truck 300 is shown.

14 and 15, the wind power generation system 100 installed on the roof of the train 400 is shown. As shown in FIG. 15, multiple turbine systems can be placed on the same vehicle after calculated aerodynamic considerations.
16 and 17, wind power generation system 100 installed on the roof of aircraft 500 is shown.

Although not shown, the wind power system 100 can also be installed in any number of other vehicle types, such as marine vessels, buses, manned and unmanned drones, and even spacecraft shuttles. When the wind power system 100 is installed on a ship, the wind power system 100 takes advantage of stormy weather and functions as a spray guard when positioned facing forward.

It can also be used on the side of a highway or between lanes with minimal modification by utilizing the wind generated by passing vehicles. Similarly, the wind power generation system 100 can also be installed on a roof where a strong and stable wind blows.
