Description

For measuring and recording wind pressure, devices are known with a wind vane rotating on a vertical axis and set in the wind. On the weather vane there is a housing (box) of the device with a protruding outwardly protruding rod, fitted with a cup or a disk at the protruding end. Under the pressure of the wind on the surface of the cup or disc, the stem moves, overcoming the effect of the load. The movement of the rod with the help of a cable is transmitted to the movable part of the recording mechanism, thus recording all the changes in wind pressure over time.

In such devices, a record is made of changes in wind pressure acting in a horizontal direction, and if the wind direction does not coincide with this direction, then a record of the horizontal component of the wind pressure is produced.

Proposed according to the invention, the device is made basically the same as described above; its peculiarity lies in the fact that it makes it possible to register separately both horizontal and vertical components of wind pressure, for

what it uses is an extra vertical rod installed in the same case: ukreilenky in the guides to allow its displacement by the wind in the vertical direction. At the upper end, the rod is provided with a horizontally reinforced disc, provided with circumferentially edges with edges beveled in the direction of the wind.

Proposed, according to the invention, the device shown in the drawing.

On a tower with a small platform at the top, a thrust roller bearing 24 is mounted in the cage 25. A tube 21 passes through it, lowered to the room where the readings are recorded.

At the upper end of the pipe there is a reinforced flat box 29 with a door and wind vane wings 30. The box contains pressure receivers of the horizontal and vertical wind components, transmitting these pressures and wind rumblings using cables and pipes to the laboratory room.

The reception of horizontal wind pressures serves as a concave parabolic surface 18. The receiver is mounted on the rod 17. The rod passes through the opening into the box 29, where it can move in the guide rollers 16, which ensure the translational movement of the rod 17 in the horizontal direction. A connecting rod 15 is attached to the end of the rod. The other end of the connecting rod is connected to the finger of block 13. A shank is screwed to the bottom of the block. A thin chain comes down from the block groove, to the end of which is attached a thin and light cable 27. This cable goes down to the laboratory room .

The receiver of the vertical pressure component consists of a flat disk, the periphery of which is attached to the ring 1. The ring is designed so that its height is zero on the direction of the wind and that protrudes up and down from the disk by about 1 cm. The NAS disk; Ken on the rod 2. The latter is located vertically and can freely slide in two ball bearings. One of them 4 is mounted on the upper end of the auxiliary tube 5. The second ball bearing 12 is mounted inside the box. Thanks to these two ball bearings, the shaft 2 is in a vertical position and can be freely lowered and raised. From the bottom of the stem, a thin cable 26 runs down into the tube 2 /. Inside the box at the stem 2 there is a nail 6, for which the tube is suspended by cutting 7 to the shoulder 8 of the balance beam, having a forked shape on this shoulder. On the right shoulder of the rocker arm there is a pattern of weight 10. The arrow of the balance is a ball fitted with heavy lentils 11. The receiver of the wind direction is the wing of the wind vane 30, fixedly connected to the box 2S. The latter is rigidly connected to the pipe 21 by means of the flange 20 and the braces 22. Thus, when the vane is turned, the pipe is rotated to the same angle.

The device operates as follows.

The pressure of the horizontal component of the wind on the receiver is 18 s but

In the case of the connecting rod 15, the block 13 is transmitted, which is connected with the hammer 19 connected to it and is rotated. From the block 13, a chain is wound and a cable 27 and an index connected to it, which is associated with the writing mechanism, is lowered inside the pipe 21. Upon the termination of the wind, the 19 ticker returns the entire system to its original position.

The operation of the vertical component is completely identical to the operation of the horizontal component. Wind generates pressure on the disk. The displacement of the disc causes a displacement of the rod 2 and the cable 26. The operation of all the parts is transmitted to the pen, which writes on the tape.

As the wind rises, the system rises and the pen writes from bottom to top; In descending flows, the system descends — the pen writes from top to bottom. If the wind pressure ceases, then the IJ, striving to return to the equilibrium position, brings the entire system to its original position.
