SU128154A1 - Hydrostatic recorder catastrophic sea waves and floods - Google Patents

Description

A disadvantage of the known devices for recording sea waters is that they do not allow the recording of parameters of catastrophic sea waves and floods.

The described device does not have this disadvantage. This is achieved by the fact that for automatic registration of the amplitude and period of the sea. WAVES uses the hydrostatic pressure caused by it, and uses a bellows, the bottom of which is spring-loaded and able to change its position depending on the magnitude of the hydrostatic pressure acting on it and transmit it using a lever system and pen recorder on the drum, driven by movement clockwork which is activated simultaneously with the operation of the bellows when the electrodes are closed by the sea wave.

FIG. 1 shows a device in vertical section; in fig. 2 the same, In terms of.

The pressure receiver is a spring-loaded bellows / fastened on the basis of device 2. A linear movement of the bottom of the bellows, proportional to the hydrostatic pressure, is converted into rotary motion of the axis 4 and the arrow o by means of a metal flexible CONNECTION and rod 5. The spring 6, mounted on the axle, provides a constant tension of the flexible coupling and eliminates the backlash connection errors. The parameters of the measuring spring of the bellows and the kinematic transmission are calculated so that the bottom of the bellows is displaced 3 mm under the action of hydrostatic pressure of 1 atm (wave height tsunami 10 m) causes the end of the arrow to move 100 mm. The recording is done with slate on coated paper. The paper is wound on a drum 7 driven by a clockwork movement.

A full turn of the drum takes 6 hours with a tape speed of 1 mm per minute. The clock mechanism can work without winding 18-20 hours.

To eliminate the effect of temperature changes on the instrument readings, the arrow is attached to the axis through a bimetallic thermocoupler 8. In the recorder, the drum has a fixed arrow 9 of the pen, drawing on the tape the base line from which the level values are read using a pallet. The device is closed by a sealing skin 10.

The recorder is located on the coast above the tidal level fluctuation zone of the sea level and is turned on automatically when approaching the device of the sea wave. For this, an electrode device (ring and rod) was fixed on the outside of the base of the device on the outside, which is intended to turn on the watch mechanism. When the recorder is flooded with a catastrophic wave, the sea water closes the electrodes of the switching device. In this case, the electro-mechanical relay is triggered, the measles of which releases the balanced wheel of the additional movement of the Clockwork; the clock is thus started and the tape drum is set in motion.

The electrodes of the switching device and the registering bellows are at the same level in the device, therefore simultaneously with the moment of turning on the clock mechanism for changing the level, it is perceived by the bellows and recorded. This method of switching on the recorder is different from all other known methods.

When the water drops after the first catastrophic wave and the electrodes open, the clock drum rotates, which is achieved with the help of a pawl, fixing the position of the relay's bark at the moment of its activation. This allows the amplitudes and magnitudes of the periods of all subsequent catastrophic waves to be determined.

After the termination of the catastrophic waves, the recorder cover is removed and the clock is stopped by pressing a special lever 12 located at the drum.

To check the switch on device in the recorder; a toggle switch 13, connected in parallel to the electrodes and during control, includes an electrical circuit of the device. The operation of the device is provided with a dry battery, for example GB-70 13.

Electrode device and bellows are closed with a cylinder.

To screen out wind waves, the protective cylinder of the bellows has a damping hole, the size of which is chosen so that the hydrostatic pressure oscillations caused by wind waves do not pass to the bellows.

The device is fixed in a special concrete base capable of withstanding the dynamic pressure of catastrophic waves. The base has two louvered doors located on opposite sides. The dimensions of the inner base chamber should allow the recorder to be fixed on the anchor bolts and free to remove and put on the cover of the device during control inspections and when reloading tapes and power supplies. Blinds on the doors are designed to protect the inner chamber from falling precipitation in the form of rain and sing, as well as from mechanical damage. At the same time, they should not impede the passage of seawater to the device during the movement of catastrophic waves. A hydrostatic recorder can be used to record floods (for example, Leningrad).
