Problems solved by technology

[0003] According to the sun protection cover structure of a flow measuring instrument published by China Patent Network CN211013122U, although it solves the problem that the flow measuring instrument is installed on the surface of the pipeline, the flow measuring instrument is exposed to the air for a long time. Under scouring, the surface of the flow measuring instrument will be corroded, but the flow meter is mostly directly exposed and installed when it is working, lacking measures to protect the instrument, and often affected by external environmental factors such as vibration and humidity will affect the use of the instrument

Abstract

The invention discloses an electrical automation instrument protection device which comprises a supporting plate, a box body is fixedly arranged on the supporting plate, damping devices are symmetrically and fixedly arranged on the upper inner wall and the lower inner wall of the box body, each damping device comprises a first fixing plate, a first spring and a second fixing plate, and the first fixing plates are installed on the upper inner wall and the lower inner wall of the box body. The two first springs are fixedly arranged on the side, away from the inner wall of the box body, of the first fixing plate, the second fixing plates are fixedly arranged at the ends of the sides, away from the first fixing plate, of the first springs, and first semi-annular plates are fixedly arranged atthe two ends of the first fixing plate. The device has the advantages that the vibration amplitude of the annular protective frame is reduced, the vibration amplitude of a flow meter is reduced, the reading accuracy of the meter is improved, the service life of the meter is prolonged, and the effects of damping and protecting the flow meter are achieved.

Description

technical field [0001] The invention relates to the field of instrument protection, in particular to an electric automation instrument protection device. Background technique [0002] Automated instruments are composed of several automated components and are automated technical tools with relatively complete functions. They generally have several functions at the same time, such as measurement, display, recording or measurement, control, and alarm. The automated instrument itself is a system. It is a subsystem in the entire automation system. The automation instrument is a kind of "information machine", and its main function is the conversion of information form, converting input signals into output signals. The signal can be expressed in the time domain or frequency domain, and the transmission of the signal can be modulated into a continuous analog or intermittent digital form. [0003] According to the sun protection cover structure of a flow measuring instrument publish...
