Description

The utility model relates to wind power devices based on the use of oncoming air flow to generate electricity and can be used for autonomous and uninterrupted power supply of an electric vehicle, in particular for recharging rechargeable batteries.

Known technical solution according to patent RU 2375212 C1 B60K 16/00 F03D 3/00, publ. December 10, 2009, a CAR WIND GENERATOR, which contains a shaft, a generator mounted on a support with windings on the shaft, a multifaceted prism with a nozzle of blades with the conical part attached. In front of the conical part, a visor is installed, located at an angle and fixed to the cab. The blades are fixed by welding or bolts at an angle to the faces of the prism with the possibility of their rotation by 90 degrees with the pressing of the blades by a gale wind tightly to the surface of the faces of the prism. The blades have springs, one end of which is connected to the blade, and the second to the face of the prism. Moreover, the springs are selected in such a way that they ensure, during a gale-force wind, the rotation of the blades to a position at which their surfaces are tightly pressed against the surface of the faces. The invention provides the use of two types of wind flows, namely artificial wind when driving a car and natural wind when parking. When using wind currents, the device operates as a self-managing device. Disadvantages: design complexity, lack of airflow efficiency, which leads to low generator performance.

A technical solution is known for patent application RU 2005127106 A B60K 1/00, publ. 03/10/2007, according to which the WIND GENERATOR FOR an ELECTRIC CAR, containing at least one wind generator module and a rectifier, in which the wind generator module is mounted on an electric vehicle, further comprising a flat casing, a plurality of air channels and many small wind power units installed in the air channels, are air inlets openings in the specified set of air channels directed forward in the direction of movement of the electric vehicle, air outlets in the set of air channels directed to side of the back of the electric vehicle, when the electric vehicle is moving, air enters the indicated air inlet openings of the air channels and drives a plurality of wind power units to generate electricity, and the generated electricity is supplied through a rectifier to the electric vehicle’s traction motor. An electronic relay is installed between the rectifier and the traction motor, the electric circuit of the electronic relay being connected to the battery set of the electric vehicle, therefore, when the electric power generated by the wind generator module is insufficient for the electric vehicle to move, the battery set serves to compensate for the insufficient power when the wind generator module generates excess electricity, additional electricity can be used to recharge battery battery. Disadvantages: a complex structure, a complex system of arrangement of air channels does not provide the flow required to generate electricity, respectively, low productivity of the known design of a wind generator.

Closest to the claimed is a technical solution according to patent 115019 U1 F03D 3/00, publ. 04/20/2012, ELECTRIC CAR WIND-GENERATOR, which contains a wind receiver made in the form of a confuser, a cylindrical chamber in which wind wheels are placed, a prefabricated air channel and electric generators located outside the cylindrical chamber, and it is equipped with an air cooling system, the wind receiver has an upper and lower chambers made in the form of confusers with a tangential approach of artificial air flow to the wind wheels, which are installed in a cylindrical chamber, the upper wind wheel being connected to the inner shaft, and the lower wind wheel is connected to the outer shaft, and outside the cylindrical chamber to these coaxially mounted shafts are rotors in the form of disks with a U-shaped cross section, permanent magnets are attached to the inner walls of which, the inner shaft rotates clockwise, and the external shaft rotates counterclockwise around the stators - magnetic cores with working windings, which have units for fastening to external structures, and the prefabricated air channel directly communicates with atmosphere in the stern area of an electric vehicle. The air cooling system is made in the form of an exhaust duct connected to a pipe, the outlet of which is placed in the bottom of the lower chamber. Wind wheels have the same diameter, are made of durable synthetic material and have the shape of a cylinder with external rectangular cutouts in the form of a half segment lying between two adjacent radii and occupy the area between the perpendicular dropped from the radius end to another radius and the arc enclosed between these radii. Coaxially mounted shafts are made of high strength steel. Permanent magnets have the shape of a circular ring with a rectangular cross section and are made of rare earth elements (Samarium Sa, cobalt Co). The magnetic circuit has twenty-four T-shaped sector consoles on which the working windings are located, and each eight working windings are connected in series through two and form a circular working winding, there are three such windings. The base of the magnetic circuit is made of non-magnetic material.

The disadvantage of the prototype is a complex structure, including a duct with a normal, inefficient leakage of artificial air flow onto the wind wheel and a prefabricated air duct with side arms, which complicate the design of the prefabricated air duct and create a slight aerodynamic effect. Generators are installed vertically, which makes rotation of the axis difficult, and reduces productivity. Only one half of the generator axis works - performance is very low. The system of air chambers complicates, makes the structure heavier, not reaching its goal - the air flow rate does not increase.

These shortcomings are solved by the claimed utility model.

The technical problem, which this utility model is aimed at, is to eliminate the disadvantages of the prototype by simplifying the design, rejecting the inefficient arrangement of generators, confuser, air chambers, and increasing efficiency, productivity, and reducing manufacturing costs.

To solve the technical problem, we propose the design of an electric vehicle wind generator with horizontal installation of generators, while the pulley with blades serves as an air intake. When the electric vehicle moves, a powerful stream of oncoming air is created, which can be used to charge the batteries. For this, conventional automobile generators are used.

In order to use a counter flow of air, a pulley with blades made of plastic, aluminum, titanium, etc., is put on the generator shaft. To increase productivity and rotation speed in the factory, the generator shaft is extended, a second pulley with blades is put on the generator shaft (Fig. 1, Fig. 2, Fig. 3, Fig. 4). Upgraded generators are installed perpendicular to the air flow, both on electric vehicles and stationary wind generators (windmills). The mounting rail is rigidly (for example, bolted) attached to the electric vehicle body below the level of the roof of the electric vehicle body, while the roof of the electric vehicle body has slots in the form of rectangular holes for free exit of the blades. To increase power, several generators can be installed on one mounting rail, each is rigidly mounted (for example, with bolts) to the mounting rail, and each generator contains an elongated shaft, on each of which a pulley with blades is installed on both sides of the generator. The number of slots in the form of rectangular holes in the roof of the electric vehicle body corresponds to the number of pulleys mounted on the rotor shaft, the number of pulleys corresponds to at least two for each generator, the number of generators depends on the required power, each generator is installed perpendicular to the air flow.

As a special case, with the required higher battery charging power, it is possible to install an additional mounting rail in the second row, while the generators are installed so that the pulleys with the second row of blades do not coincide with the location of the second row of pulleys in the projection front view (rear view), the slots in the roof housing are staggered and allow the use of an air stream not obscured by the pulleys of the first row of pulleys.

For example, take the option of installing a generator on the roof of an electric vehicle (Fig. 5, Fig. 6, Fig. 7). For charging, you can use one, two or more generators, depending on the power of the batteries. A car generator is used as a generator. The mounting rail (Fig. 5) is made of rolled metal (for example, a metal bar, corner, etc.) With an oncoming air stream due to the movement of the blades, the generator rotor will begin to rotate and generate an electric current. In this case, the blades should extend beyond the body of the electric vehicle by about one third, and two thirds should be closed (Fig. 7). The greater the height and width of the blades, the easier the rotation of the blades of the generators. Recommended shape of the blades - Fig.8, Fig.9, Fig.10, Fig.11.

On electric vehicles with the installation of a second, through roof, which protects against atmospheric precipitation, you can create the effect of a turbine. The air flow will begin to press the blades, which will increase the air flow to each generator. This principle, which is described for electric vehicles, can also be used on stationary wind generators (windmills) to generate electrical energy (Fig. 12, Fig. 13). The windmill works on the principle of a weather vane. The blades of a windmill are straight and should be closed by protection by about two-thirds (Fig. 12, Fig. 13).

The inventive utility model will allow electric vehicles to move without additional recharging the batteries, will reduce manufacturing costs, increase the productivity of the wind generator.

The technical result is a simplification of the design of the wind generator, while increasing its productivity and reducing the cost of its manufacture.

The technical result is achieved due to the design of the wind generator, which contains at least one generator, at least one rotor shaft, at least one pulley, blades, characterized by the execution of the rotor shaft elongated, protruding from both sides of the generator, the horizontal location of the shaft to the vertical axis of the electric vehicle, perpendicular electric vehicle motion vector; the presence of a mounting rail; each generator is rigidly mounted on a mounting rail; at least two pulleys with blades mounted on the rotor shaft, one on each side of the generator; the mounting rail is rigidly attached to the body of the electric vehicle below the level of the roof of the body, while the roof of the body of the electric vehicle has slots in the form of rectangular holes for the free exit of the blades, the number and location of slots corresponds to the number and location of pulleys mounted on the rotor shaft, the number of pulleys corresponds to at least two on each generator, the number of generators depends on the required battery recharge power, with each generator installed perpendicular to the air flow. As a special case, the wind generator contains an additional mounting rail in the second row, while the generators on the second additional mounting rail are installed so that the pulleys with the blades of the second row do not coincide with the location of the pulleys of the first row, the slots in the housing under the blades are staggered and allow use airflow not obscured by the first row of blades. Another special case in which the mounting rail is made of rolled metal. Another special case in which a car generator is used as a generator.

An example implementation.

To use a counter flow of air, a pulley with blades made of plastic, aluminum, titanium, etc., is put on the generator shaft. To increase productivity and rotation speed in the factory, the generator shaft is extended, a second pulley with blades is put on the generator shaft (Fig. 1, Fig. 2, Fig. 3, Fig. 4). Upgraded generators are installed perpendicular to the air flow, both on electric vehicles and on stationary wind generators (windmills). The mounting rail is rigidly (for example, bolted) attached to the body of the electric vehicle below the level of the roof of the body of the electric car, while the roof of the body of the electric car has slots in the form of rectangular holes for free exit of the blades (Fig.6). To increase power, several generators can be installed on one mounting rail, each is rigidly mounted (for example, with bolts) to the mounting rail, and each generator contains an elongated shaft, on each of which a pulley with blades is installed on both sides of the generator. The number of slots in the form of rectangular holes in the roof of the electric vehicle body corresponds to the number of pulleys mounted on the rotor shaft, the number of pulleys corresponds to at least two for each generator, the number of generators depends on the required power, each generator is installed perpendicular to the air flow. If you need a higher battery charging power, you can install an additional mounting rail in the second row, while the generators are installed so that the pulleys with the blades of the second row do not coincide with the location of the pulleys of the second row in front view (front view, rear view), slots in the roof casing is staggered and allows the use of an air stream not obscured by the blades of the pulleys of the first row.

For example, take the option of installing a generator on the roof of an electric vehicle (Fig. 5, Fig. 6, Fig. 7). For charging, you can use one, two or more generators, depending on the power of the batteries. The mounting rail (figure 5) is made of rolled metal (for example, a metal bar, corner, etc.)

The counter-flow of air due to the movement of the blades of the generator rotor will begin to rotate and generate an electric current. In this case, the blades should extend beyond the body of the electric vehicle by about one third, and two thirds should be closed (Fig. 7). The greater the height and width of the blades, the easier the rotation of the blades of the generators. Recommended shape of the blades - Fig.8, Fig.9, Fig.10, Fig.11.

The inventive utility model can be implemented with a change in the design of the generator (figure 1, figure 2), the manufacture of pulleys with straight blades (figure 3, figure 4, figure 8, figure 9, figure 10, figure 11), manufacturing a mounting rail for an electric vehicle and installing generators with vane pulleys on an electric vehicle. For the manufacture of a wind generator (Fig, Fig, 13) there are no difficulties.

The inventive utility model can significantly simplify the design of the wind generator of an electric vehicle and increase the productivity of using oncoming air flow and wind power to recharge batteries on electric vehicles and generate electricity on wind generators using vane generators installed perpendicular to the air flow with straight blades, by changing the design of the generator and horizontal location of the generator shaft.
