INVENTION
Russian Federation Patent RU2015409
DEVICE FOR CONVERTING FLOW OF AIR IN MECHANICAL WORK
Name of the inventor: Peter S. Milchenko
The name of the patentee: Milchenko Petr Semenovich
Address for correspondence:
Starting date of the patent: 1991.03.12
Use: in the wind industry. The inventive device for converting a stream of air into mechanical work comprises a rectangular blade movably mounted on a horizontal crankshaft 1, which at each end of the fixed guide 3, is pivotally connected to the blade 2 earring 4 whose length is equal to the radius of the crank of the crankshaft 1. The crank radius equal to 1/4 the blade width of 2. The crankshaft 1 and the carrier 3 are connected to transmission shaft 5 by means of closed circuit 7 through the sprocket 6 with the transmission ratio 1: 2.
DESCRIPTION OF THE INVENTION
The invention relates to wind power engineering and can be used to provide power to various customers. Wind energy has been used by a wind wheel, the blade of which was the efficiency of 0.15.
To increase power by increasing the efficiency of the device have been proposed with a rectangular blade having a reciprocating motion. The prototype of the claimed proposal is a device that stroke of the blade it is idle.
The purpose of the invention - the creation of high-power wind turbine while reducing metal consumption.
This object is achieved in that the device vanes are directly on the crankshaft, both ends of which are installed carrier coupled to lineshaft closed circuits. The average crankshaft connected to the transmission shaft with the transmission ratio 1: 1 and the carrier 1: 2. No idle blades Lockers installation increased plant efficiency. Transmission shaft that accepts the load on the crankshaft makes it possible to perform it lightweight as crankpins carry the load applied only at the base of the cranks.

Figure 1 shows an arrangement of a wind turbine; Figure 2 - operation of the device.
On the crankshaft 1 are rectangular blades 2, 3 are connected to the carrier 4. The crankshaft earrings 1 and carrier 3 are connected to the transmission shaft 5 chain drive (bevel gears can be a transfer roller) 6, sprockets and chains 7. On the frame 8 mounted brackets 9 It relied on by the crankshaft 1.
Device operates as follows
Pressure air blade 2 slidably mounted on the crankshaft 1, tends to become parallel to the air flow and do it with the help of earrings 4 carrier 3. The sequence of movement of the blades is shown in Figure 2, taking the starting position, the blade 2 is derived from this position through the guide 3 and 4 earrings crankshaft 1 and starts its reverse side. Blade 2 sends her wind pressure of the crankshaft 1. The blade 2 connected earrings 4 with the carrier 3, moves successively occupying the position shown in Figure 2. The projection on the blade perpendicular to the direction of the wind increases and decreases as the sine of the angle of rotation of the carrier. PTO is performed by the transmission shaft 5.
CLAIM
DEVICE FOR CONVERSION OF AIRFLOW into mechanical work, comprising a rectangular vanes kinematically connected with a horizontal crank shaft, characterized in that, in order to increase capacity and reduce the metal content, the device is provided with a transmission shaft, the blades are movably mounted on the crankshaft, each end of which is fixed carrier pivotally connected to said blade pierced whose length is equal to the radius of the crank of the crankshaft, with the crank radius equal to 1/4 the blade width and the crankshaft and the carrier are connected to the transmission shaft via closed circuit through sprocket gear ratio of 1: 2.
