WIND SPEED RELAY Russian patent published in 2022 - IPC H01H35/06 H01H36/00 G01P5/06 

FIELD: wind power engineering.

SUBSTANCE: device relates to means of control of a wind speed; it can be used wind power engineering and other industrial installations for emergency and warning signaling. The device contains vertical shaft (1) made with the possibility of axial movement. On shaft (1), anemometric turntable (2) is fixed, rotation of which is limited with stops (6, 7). On a lower end of shaft (1), permanent magnet (3) is installed, interacting with reed switch (4) through a magnetic field. Turntable (2) is mechanically connected to magnet (3). Upper hinge (9) connected to turntable (2) is installed in case (8), asymmetrically to the axis of rotation of shaft (1). Lower hinge (11) is installed in case (8) in a direction of rotation of upper hinge (9). To upper hinge (9), with its upper end, inclined rack (10) is attached, a lower end of which rests against lower hinge (11).

EFFECT: increase in wear resistance and durability of a device.
