Description

Already known are devices for measuring wind direction and speed, in which the wind direction is determined by assistance from the wind. wind vane, and wind force with a pointer mounted on the weather vane in the form of a movable plate deflected by the wind, and the wind force is judged by the deflection angle of the plate under the action of the wind.

A feature of the device proposed according to the invention, based on the same principle, is the use of a second additional curved plate fixed on the same axis as the main plate and deflected along with it by the wind.

The drawing shows the proposed device. It consists of a movable system (in the form of a wind vane 1 and (plates 2 and 10) mounted on axis 3 and fixedly fixed on the same limb axis 11 s

, put on it the names of 1 rhumbov. On the tail end, the vane blade is provided with cuts and bends that serve for

damping and reducing oscillation of the weather vane. In the opposite tail side of the weather vane 1

there is a folding counterweight 4, which, when the device is in the working position, should be positioned horizontally. On the axis 3 and on the horizontal axis 5 two plastics 2 and 10 are suspended. These plates are provided with cutouts in the middle parts, rigidly fastened to each other and inclined in RELATION to each other at a certain angle. Under the action of the wind, the entire system is rotated and installed in a certain direction, and the plates 2 to 10 are deflected at one or another angle, depending on the wind speed. On the weather vane there is a scale, on which the wind speed is usually counted, and its direction is marked on the limb 11.

The upper plate 10 differs in pitch from the lower 2 and serves as a dynamic resistance to the lower plate, which makes it possible to reject the use of several plates with different weights, as is required in normal (wind plate).

The mobile system of the device has a ring 8 below, through which the axis 3 of the device is passed. Ring

allows you to judge the vertical installation of the device. The upper end, the axis of the device rests on a cone 7, which is rigidly fastened to the frame 6 of the device. The lower end of the axis, under the scraper limb, ends with a cone 9 (handle) that can be put on the pole.

Subject invention

Measuring the speed and direction of the wind, made in the form of. A gate mounted by a wind plate mounted on a weather vane and provided with a counterweight, characterized in that a thora, a notch plate 10 attached at an angle to the main plate 2 are used as a counterweight.
