Description

TECHNICAL FIELD

The invention relates to wind-powered devices, in particular to wind-powered devices.

BACKGROUND OF THE INVENTION

Renewable energy is one of the fastest growing energy sources, and wind energy is probably the most common source of renewable energy. As a result, there is a great need for equipment capable of converting wind energy into rotational motion that can be used to produce other forms of energy, such as electricity. Such devices must be simple in construction and maintenance, easy to install, and highly efficient.

Patent document FR2541383A1 (published 24/08/1984) discloses a wind turbine design that includes a multi-vane impeller mounted between at least two walls to direct wind energy through the largest diameter of the turbine. The wind turbine can be installed in a horizontal or other position.

Pat. The impeller shaft and at least one pair of wind blades are housed in a closed housing. At least two wind vents form a sloping wind duct so that wind can flow into one of the openings and flow through the other orifice, thus forcing the blades to rotate in the wind flow channel while rotating the impeller shaft. The system is simple in design, safe to use, low noise, high efficiency and easy to maintain.

Patent document CN109058040A (published 21/12/2018) discloses a vertical shaft impeller module and an electrical generating device. The vertical shaft impeller module includes a support frame and impeller design. The design of the impeller includes a shaft rotating in a vertical direction and a plurality of blade assembly units which are mounted on the shaft rotating in the radial direction in an evenly spaced manner. Blade assembly units include assembly housings; a plurality of unit housings are located on the housing of each assembly unit; the housing opening is located in each housing of the unit, and the housing opening can only be opened clockwise or counterclockwise; and the vertically rotating shaft is mounted in the housing vertically, wherein the upper mounting end is located in the upper part of the vertically rotating shaft, and the lower mounting end is located in the lower part of the vertically rotating shaft. The power generation unit includes a vertical shaft impeller module. The vertical shaft impeller module has a modular design and can be assembled according to the existing conditions of use to ensure high power generation. The design of the blade assembly units also ensures the high force generated by the blades and the low air speed required to rotate the impeller.

All the above-mentioned devices are characterized by paddle blades, the production and assembly of which require a number of technological operations. The present invention uses a disc-shaped flat-surface impeller that has no blades. As a result, the design of the impeller is simpler compared to traditional vane impellers.

SUMMARY OF THE INVENTION

This description describes a wind-blown device that converts the energy of a wind stream into rotational motion. The construction of this device consists of a housing in which a shaft is mounted in a vertical direction, rotating about its axis, on which is mounted an impeller inclined at an angle. The angle of inclination of the impeller with respect to the vertical axis of the shaft is fixed or variable. The fixed angle of inclination of the impeller is ensured by the use of a guide and the variable angle by the mechanism of angle of inclination. The incoming wind or air flow through the housing openings (guides) is directed to the left or right side of the impeller, depending on the arrangement of the guides, where the incoming wind / air flow rotates the impeller mounted on the shaft. At the ends of the rotating shaft projecting beyond the housing, other devices requiring rotational movement, such as an electric generator or the like, can be connected.

The wind-powered device presented differs from its analogues in that it uses a disc-shaped impeller that does not have blades, grooves or other additional structural elements that can be attached to the impeller as required. This simplifies the design of both the unit itself and the impeller, and facilitates maintenance of the unit. Due to its simple design, the unit can be operated outdoors and / or indoors. The unit is designed to work with both wind power and airflow energy generated by other units such as air blowers.

BEST IMPLEMENTATION OPTIONS

This description describes a wind-blown device that converts the energy of a wind flow into a rotational motion. The construction of this device consists of a housing (1) in which a shaft (3) is mounted in a vertical direction, rotating about its axis, on which is mounted an impeller (3) inclined at an angle. The incoming wind or air flow through the housing openings (8, 9) (guides) is directed to the left or right side of the impeller, depending on the arrangement of the guides, where the incoming wind / air flow rotates the impeller (2) mounted on the shaft (3). At the ends of the rotating shaft (3) projecting beyond the housing (1), other devices requiring rotational movement, such as an electric generator or the like, can be connected. The wind-powered device presented differs from its analogues in that it uses a disc-shaped impeller that does not have blades, grooves or other additional structural elements that can be attached to the impeller as required. This simplifies the design of both the unit itself and the impeller.

The wind-blown installation shall include at least (Figure 1):

a housing (1) comprising horizontally arranged upper (5) and lower (4) parts connected to at least two side walls (6, 7) arranged on each side of the housing (1), where the side walls (6, 7) are inclined inwardly of the housing to form openings (8, 9) (holes) in the sides of the housing through which the flow of wind / air flows;

a shaft (3) rotating about its axis and mounted in a vertical position on supports (10) connected to the upper (5) and lower (4) parts of the housing (1);

a impeller (2) mounted on a rotating shaft (3) by tilting it at an angle to a vertical axis of the shaft (3), where the impeller is in the shape of a round disc.

The housing (1) in the case of the present invention is a cavity into which the flow of wind / air flows and in the central part of which a shaft (3) with a impeller (2) mounted on it is fastened. As a result, the side walls (6, 7) of the housing (1) are connected perpendicularly to the upper (5) and lower (4) parts. The side walls (6, 7) of the housing (1) are inclined towards the inside of the housing, thus forming wind / air flow inlets (8, 9) on each side of the housing. The incoming wind / air flow through the openings (8, 9) is directed to the left or right side of the impeller, depending on the arrangement of the openings (8, 9), where the incoming wind / air flow rotates the impeller (2) mounted on the shaft (3), rotating the shaft at the same time (3).

The shaft (3) in the case of the present invention is an elongate element made of a mechanically strong material, such as metal, plastic, or other materials having similar mechanical-physical properties. The length of the shaft (3) can be selected according to the design of the wind flow device according to the present invention. The purpose of the shaft (3) is to transmit the rotational movement (torque) obtained from the coupling impeller (2) rotating together. The shaft (3) is mounted on at least two supports (10), such as magnetic and / or radial rolling bearings, to ensure a smooth rotation of the shaft about its longitudinal vertical axis. Said supports (10) hold the rotating shaft (3) in the required position and transmit the applied loads to the housing (1). The shaft (3) in the housing (1) is fastened so that both ends protrude beyond the upper (5) and lower (4) parts of the housing (1). This allows other devices to be connected to the projecting ends of the shaft (1) to which the torque of the rotating shaft (3) can be transmitted.

The impeller (2) in the case of the present invention is a round flat disk having a thickness dimension many times smaller than the diameter of the disk and having smooth outer surfaces, i. y. has no blades, grooves or other additional structural elements that can be attached to the impeller as required. The purpose of the impeller (2) is to convert the flow of wind / air flowing through the openings (8, 9) of the housing into a rotational movement, which is further transmitted to the shaft (3) on which the impeller (2) is mounted. To ensure efficient operation of the impeller (2), the latter is mounted on the shaft (3) at an angle to the longitudinal vertical axis of the shaft. In this way, the flow of wind / air flowing through the openings in the housing (6) bounces off the inclined outer surfaces of the impeller (2), forcing the shaft (3) on which the inclined impeller (2) is mounted to rotate about its vertical axis. The impeller (2) is attached to the shaft (3) in such a way as to ensure an even transmission of rotational movement between the two elements. The impeller (2) can be connected in any longitudinal part of the shaft (3) so that the inclined impeller (2) does not come into contact with the housing. The impeller (2) can be connected to the shaft (3) by means of a non-removable connection, for example by welding, or by means of a detachable connection, for example by means of a fastening element. The angle of inclination of the impeller (2) with respect to the vertical axis of the shaft (3) is fixed or variable, said angle being variable from 10 ° to 80 °. A fixed angle of inclination of the impeller is ensured by structural means, for example by using a guide (11) fixedly mounted on a shaft (3) to which the impeller (2) is fixed.

The angle of inclination of the impeller (2) with respect to the vertical axis of the shaft (3) can be changed by an angle of inclination mechanism (Fig. 4), said mechanism comprising at least two guide plates (12), lower (13) and upper (15) plates, rolling elements ( 14) an element (17) for attaching the impeller (2) to the shaft (3). At least two guides (18) arranged in the vertical direction are hinged to the lower plate (13), which is in a fixed stationary position. An upper plate (15) is connected to the lower plate (13) by means of rolling elements (14), to which the impeller (2) is fixed, and the shaft (3) is connected to the impeller (17) fixedly connected to the impeller (2). shaft (2). As the impeller (2) rotates about its vertical axis of rotation, the shaft (3) and the top plate (15) rotate together, and the angle of inclination of the impeller (2) is changed by changing the guides (18), the ends of which protrude beyond the lower part of the housing (1) ( 4), position in the longitudinal direction.
