Description

BETPOIffMEMHOS DEVICE.

The invention relates to the field of meteorological instrumentation, in particular to primary sensors for determining wind speed. In addition, it can be used to determine the motion parameters of liquid and gaseous media.

Wind receiving devices of a vertical type of the most diverse classes and types, made of various materials, are known. They are included in wind measuring devices and allow to determine the studied wind parameters. .

p. 68-72 / containing a cross, the shoulders of which are located

peripheral

at an angle of 120 °, a hemisphere made of brass is fixed at the end of each shoulder. The crosspiece under the influence of the movement of air currents rotates on a vertical axis, the lower end of which is connected through a worm device with an electromechanical counter of the number of revolutions of the cross.

However, the remote device has a relatively low threshold sensitivity, and it is up to 0.8 m / s.

A known construction of Japanese specialists, similar to the above. / Cm, ibid. /. The only difference is in the material of the primary sensor - cup-shaped hemispheres. They are made of this material is lighter, which allows to increase the threshold sensitivity. MKI: e 01 P 5/00

up to approximately 0.6 m / s.

However, even this value does not allow fixing the values of weak wind speeds, up to 1 m / s.

The last analogue is 7 closest to the proposed one.

The purpose of this technical solution is to increase the threshold sensitivity while reducing the dimensions of the device.

This goal is achieved by the fact that in the wind receiving device containing the crosspiece, made with the possibility of rotation around the vertical axis in the form of arches spaced at the same distance, at the peripheral ends of which there are sensitive elements of cup-shaped fors, the shoulders-crosses are made hollow, and the sensitive elements are made of lightweight material with a density of less than 2.8 g / cm.

The device is illustrated by drawings, where figure 1 shows a schematic representation of a wind receiving device, and figure 2 an example of a wind receiving device.

The inventive device consists of a cross 1, mounted on a vertical axis 2 and made with the possibility of rotation around it, in the form of shoulders spaced at the same distance, on the peripheral ends of the shoulders there are sensitive elements 3 of a cup-shaped shape. Worm thread 4, articulated with gear 5, on which earring b with permanent magnet 7, stop 8, sealed contact 9 located in the chain are coaxially freely located

press the upper point, after which its free-fall to the lower point is carried out. Falling, the earring 6 with the magnet 7 closes the tight contact 9, which is located in the circuit of the power source 10 and the electromagnetic counter of the number of short circuits

Example i.

The device consists of a cross, which is made of thin-walled nickel tubes with a diameter of 5 mm and a wall thickness of 0.3 mm, rigidly bonded to the axis of rotation, made of steel with a diameter of 4 mm. Sensitive elements are made in the form of organic glass hemispheres with a specific gravity of 1.8 g / cm. For the manufacture of hemispheres, matrices and a punch were made, between which a plexiglass plate preheated to 120 ° was placed and then a hemisphere was formed between the matrix and the punch under pressure. Prepared hemispheres strengthen at the ends of the shoulders of the cross.

This device allows you to increase the threshold sensitivity to 0.3 m / s while reducing the size and weight of the device.

Variants of manufacturing sensitive elements from materials with a density exceeding 2.8 g / cm were tested. Such wind receiving devices showed a sensitivity similar to the sensitivity of the devices described above. In analogues, which does not suit users when measuring low wind speeds. U - C, A. Volkov
