FIELD: machine building.
SUBSTANCE: invention relates to machine building, in particular to protecting devices of safety systems for explosive equipment. In the automatic safety device of safety systems in emergency situations, containing a system of sensors of the hazardous area sensing system, including sensors configured to exceed the maximum permissible concentrations of chemically hazardous substances present in this zone, and the maximum permissible levels of radioactive substances, as well as an infrared sensor that reports the occurrence of a fire, the signal from either of the sensors is fed to a common microprocessor that processes these signals and issues a control signal to the executive device, including emergency ventilation, in addition, a safety system in emergency situations is additionally equipped with backup safety component, made in the form of explosion proof panel with an emergency alert system containing a metal armored carcass with metal armored plating and a filler-lead, which has in its ends four fixed branch pipes, and in the cover of the explosive object, four support rods are rigidly embedded, which are telescopically inserted into the fixed pipe-supports of the panel, the filler is made in the form of an air-lead dispersed system, the lead being shaped like crumb, and the supporting rods are made elastic, to the ends of the support rods, on the side facing the metal frame, a damping element is attached, the damping effect of the impact loads of the panel on the stop sheets. Between the additional elements and the metal frame with armored metal lining, support bushings are fitted with fast-disintegrating material, for example glass, such as triplex, the emergency notification system with a safety indicator consists of a "weak link" attachment point in the safety system of an explosive object reacting to an emergency situation, for example, in the form of a safety indicator fixed between flanges, which are rigidly fixed on the upper part of the armored metal plating of the metal frame of the explosion proof panel, and in the upper part of the cover of the explosive object at the opening designed to relieve excess pressure, the safety indicator consists of a strain-sensitive sensor, for example a strain gage, the output of which is connected to a signal amplifier, for example a strain gage, and the output of the strain amplifier is connected to the input of the emergency warning system.
EFFECT: increase the effectiveness of protection of technological equipment from emergency situations by increasing the speed and reliability of the system's operation.
