Switchgear with vibration suppression and vandal protection.
The method of claim 1,
The first attenuation unit
a vibration-proof rubber formed on the base and absorbing vibration transmitted from the base by elastic force;
a pedestal formed on the anti-vibration rubber so that various members can be coupled thereto;
a support formed on the lower surface of the housing so that various members can be coupled thereto;
a buffer cylinder formed between the pedestal and the support and configured to support the housing by operating a piston according to the inputted fluid;
a buffer spring formed between the support and the support to press the housing toward the upper side by an elastic force;
A damping pump formed on the upper portion of the base and connected to the buffer cylinder through the pedestal for supplying and discharging a fluid into the buffer cylinder to generate vibration in the reverse direction according to the generated vibration to suppress the vibration transmitted to the housing; ;
A fluid tank connected to the attenuation pump to store the fluid supplied or discharged to the attenuation pump; characterized in that it further comprises
Switchgear with vibration suppression and vandal protection.
The method of claim 1,
The second attenuation unit
a pressure cylinder formed to rotate at one upper corner of the housing and having one end connected to the wire so that a piston protrudes or is inserted according to the tension of the wire;
a transfer rail and a linear motor formed on the other inner surface of the housing and having a pulley for changing the direction of the wire according to a position to vertically elevate the transfer block;
a winding motor formed on the upper portion of the base to change the tension of the wire by winding the wire to suppress vibrations applied to the housing in a horizontal direction;
The transfer block is vertically moved according to the vibration sensed by the control unit, characterized in that it is possible to adjust the direction of the force applied according to the tension of the wire.
Switchgear with vibration suppression and vandal protection.
The method of claim 1,
the control unit
a vibration sensor embedded in the base to measure vibration transmitted from the base;
an attenuation sensor formed on the housing to measure vibration transmitted to the housing;
and an excitation motor embedded in the base to generate a reverse frequency of the vibration measured by the vibration sensor to cancel the vibration.
Switchgear with vibration suppression and vandal protection.
