Description

The utility model relates to shipbuilding, in particular, to measuring units for monitoring systems of torsional vibrations arising in the shafting of ship power plants.

Known block of the "ZetLab" system, which has a housing in which the measuring module and the interface converter are located, connected to each other, which allow receiving signals from torsional vibration sensors and processing them with further data output to a personal computer (see "ZetLab. Measuring system for torsional vibrations fluctuations "[Electronic resource]: https://zetlab.com/shop/sistemy-pod-kluch/avtomatizirovannye-stendy/sistema-izmereniya-krutilnyih-kolebaniy/). The disadvantage of the device is the absence of an information display and a sensor for monitoring the temperature and humidity of the air inside the unit body.

The closest in technical essence is the measuring unit from Geislinger (Austria). The device has a housing in which on mounting racks are placed and rigidly fixed: a microcontroller connected to a torsional vibration measurement module, a power supply unit and an information display (see page 4 of the catalog "Geislinger Monitoring. Catalog Version 5.4", Austria, 2018, - 30 s .). However, the device does not allow to control vibrations of the shafting elements of the ship's power plant, and there is also no possibility of controlling the temperature and humidity of the air inside the hull (see "Russian Maritime Register of Shipping. Rules for the Classification and Construction of Sea-Going Ships. Part VII. Mechanical Installations". ND No. 2- 020101-138, SP-b. 2021 .-- 117 p. (Electronic edition)).

The technical result is an increase in the efficiency of the device when using it.

It is achieved by the fact that the known device comprising a housing, a torsional vibration measurement module, an information display connected to a microcontroller and a power supply unit, installed and rigidly fixed on mounting racks fixed on the base of the housing, additionally has a vibration measurement module for bearings and gearboxes of a shafting installations and a sensor for measuring air temperature and humidity, connected to the microcontroller and rigidly fixed on the mounting racks.

The proposed device is schematically shown in the drawing, Fig. 1 - general view.

The device has a housing 1, a microcontroller 2 located in it, connected to it: a torsional vibration measurement module 3, an information display 4, an air temperature and humidity sensor 5, a vibration measurement module 6, a power supply unit 7. The power supply unit 7 is connected to a microcontroller 2 and an information display 4. In this case, microcontroller 2, torsional vibration measurement module 3, information display 4, air temperature and humidity sensor 5, vibration measurement module 6, power supply 7 are installed and rigidly fixed and placed on mounting racks 8.

The device works as follows.

The torsional vibration measuring module 3 and the vibration measuring module 6 receive information from the shafting sensors of the ship's power plant (not shown in the drawing), transmit the information to the microcontroller 2, which transmits the data to the information display 4. The temperature and humidity sensor 5 measures the parameters of the air inside the housing 1 and transmits data to microcontroller 2. Power supply 7 provides power to microcontroller 2 and information display 4. The proposed vibration measurement module allows you to control the vibration of bearings and shafting gearboxes of a ship's power plant, which occurs, among other things, from increased torsional vibrations.

The temperature and humidity sensor inside the case allows you to avoid overheating and damage to the elements of the unit.

Positive effect - the use of a vibration measurement module, an air temperature and humidity sensor in the device makes it possible to expand the functionality of the systems for monitoring torsional vibrations of shafting of ship power plants.
