WIND SPEED RELAY FOR AUTOMATION SYSTEMS Russian patent published in 2023 - IPC G01P5/04 F03D7/04 

FIELD: wind speed control systems.

SUBSTANCE: invention can be used in wind power and other industrial installations for emergency automation and warning alarms. The device is made in the form of a weather vane with a lever fixed to the device by means of a cylindrical hinge, the axis of which is shifted relative to the shaft axis by a certain distance and is located in a horizontal plane perpendicular to the plane of the weather vane; at the end of the lever, an element in the form of a hollow ball is installed to perceive wind pressure, and the angle of rotation of the lever is limited by stops in the upper half-plane within the angle of inclination to the horizon from α₁ to α₂ with an inclination in the direction opposite to the vane shank, and the magnet is rigidly connected to the lever so that at the maximum angle α₂ of the lever, it comes into magnetic interaction with a reed switch mounted on the upper end of the shaft.

EFFECT: increase in the performance properties of the wind speed relay.
