SU67195A1 - A device for recording the indications of the aerumumbograph - Google Patents

Description

The device according to the invention is a device for recording the readings of an aerorumbograph, in which the wind direction is determined by means of a wind vane, which is turned by the wind around a vertical axis. Thus, the main task of the proposed device is the transformation of the circular rotation of the axis of the wind vane into movement of the pen recording these movements on the drum, rotated by the clock mechanism.

In known devices of this designation, a figured comb in the form of a single turn of a screw is usually fixed on the vertical axis of the vane. A slider, connected directly or through an appropriate gear, slides along the edge of the coil with the recording pen.

The device proposed according to the invention is made according to the same principle, but differs in some features, in particular, by using a device for lifting the pen from the lower part of the ridge to the top with a circular rotation of the vane; This lift is carried out using a system of three pivotally connected levers, one of which is provided with a roller rolling on a flat surface of the screw-cage cage, and the other raises the writing device when the roller cuts over the ridge cage.

The foregoing is illustrated in the drawing, which shows a diagram of the proposed device; many of the details of the latter have been omitted to make the drawing more confusing.

The main part is a cylinder 1 with an axial bore and with a helical ridge 2, for which the cylinder / is a clip. Two parallel rods 4 are screwed into the bottom of the cylinder 1а. The cylinder / is rigidly connected to the pipe 5, which passes inside the mast, carrying the box of wind receivers. At the upper end of the pipe S is fixed vane (not shown).

When the wind vane turns, the pipe 5 rotates with it, and the cylinder 1 with the ridge 2 rotates with it. Roller 5 rolls along the latter, the axis of which is fixed in the holder 6 of the writing device (for example, pen) recording the wind direction change curve on the drum driven in rotation

clockwork (drum not shown).

The holder 6 can only move in the vertical direction - up and down, for which two vertical needles 7 are fixed (one of them is not shown), passed through the guide holes 8. Depending on the position of the vane cylinder 1 with ridge 2 will be turned to that or a different angle relative to the roller 5 and the holder 6, and this latter will take the corresponding position along the height of the cylinder 1. Thus, the height of the position of the roller 5 and the holder 6 determines the rumb (direction) of the wind.

As noted above, in such a device there is a need to transfer the holder 6 from the lower end of the ridge 2 to the upper end of the latter when rotating the ridge 2 through 360 °. To accomplish such a lift of the holder 6, the upper end of the cylinder 1 is provided with a protrusion 9 located at the point of rupture of the helix 2, and a lever system consisting of pivotally connected levers 10, 11 and the connecting bar 12 is installed. The levers 10, 11 are mounted so that The gut is rotated around the fixed supports 18 and, accordingly, 19. When the roller 17 attached to the end of the lever 10 rolls onto the protrusion 9, the lever 10 with its long arm, through the aid of the bar 12, lowers the short arm of the lever //, which with its long arm lifts the The holder 6 from the lower end of the ridge 2 to its upper end.

In order for the pen to not record during this lift, an auxiliary lever (not shown in the drawing) is provided with a roller that rolls around the periphery of the cylinder 1; at the time of lifting the holder 6, the auxiliary lever roller falls into the recess in cylinder 1, and with its other end, snarling, pulls the pen away from the tape with its other end.

The recording of pressure or wind speed is carried out in the following way.

When the wind receiver is linear or angular (not shown), the cable UO lowers or rises inside the pipe 3. To the lower end of the cable 20 an index-plate 13 is attached, which by means of the legs 14 can slide along the guide rods 4, at the same time, it rotates together with cylinder 1 and rods 4. At index 13 there is a ring 15, which can only be moved up and down with the help of guide / 6 needles. A ring is attached to ring 15 — a pen recording pressure or wind speed. If the system is 13-15. is used to record one of the components (for example, horizontal) wind pressure, then a second similar system is used to record the other component (vertical), consisting of an index and a ring, connected to the rail of the second cable 21 and located below the system 13- / 5 (not shown):

All three feathers at any given moment move along the same drum generator of the recorder, making an entry on different parts of the tape.
