Description

The invention relates to protective devices used in explosive and radioactive objects, such as easily erasable panels and roofs, explosion-proof fences and dampers, overpressure valves.

A device for explosion-proof panels is known (application DE No. 19638658, IPC Е04В 1/92 dated 04/16/1998), where the possibility of raising and lowering the panel to its original place in the explosion is carried out by the action of springs inserted into the support pipes.

The closest technical solution to the claimed object is an explosion-proof panel according to the patent of the Russian Federation No. 2334063, Cl. EB04 1/92, B.I. No. 28 dated 09/20/2008 (prototype), consisting of an armored metal frame with armored metal casing and a filler - lead. In the coating of the object near the opening, four support rods are embedded that are telescopically inserted into fixed support pipes embedded in the panel. To fix the limit position of the panel, stop plates are welded to the ends of the support rods.

A technically achievable result is an increase in the reliability of operation of explosion-proof devices during an emergency explosion at the facility and ensuring the return of these structures to their original position after the explosion.

This is achieved by the fact that in an explosion-proof panel containing a metal armored frame with metal armored casing and lead filler having four fixed support pipes at the ends, while in the coating of an explosive object four support rods are rigidly fixed, which are telescopically inserted into the fixed pipes the panel supports, the filler is made in the form of a dispersed air-lead system, moreover, the lead is made in the form of crumbs, and elastically damping elements are located outside the support rods Entries, one end of which abuts against an armored metal sheathing, and the other end into abutment sheets located in the upper part of the support rods, while the elastic-damping elements are made in the form of cylindrical coil springs, the external screw surface of which is covered with vibration damping mastic, for example, type 17.

The drawing shows a diagram of an explosion-proof coating panel (or roof) of an explosive or radioactive object.

The explosion-proof panel consists of an armored metal frame 1 with an armored metal casing 2 and a filler - lead 3. In the coating of the object 7 at the aperture 8, four support rods 4 are embedded symmetrically with respect to the axis 9, telescopically inserted into the fixed support tubes 6 embedded in the panel. To fix the limit position of the panel, the stop sheets 5 are welded to the ends of the support rods 4. In order to damp (soften) shock loads when the panel is returned, the filler is made in the form of a dispersed air-lead system, the lead being made in the form of crumbs, and the supporting rods 4 can be made elastic.

Outside of the support rods are located elasto-damping elements 10, one end of which abuts against an armored metal sheathing 2, and the other into abutment sheets 5 located in the upper part of the support rods 4.

In order to damp (soften) shock loads while fixing the limit position of the panel, the ends of the support rods 4 with the stop sheets 5 welded to them are rigidly interconnected by a platform 11 to which, opposite to the frame 1, an elastic-damping element 12 is made, made in the form of a cone , the top of which is directed towards the action of the shock load from the opening 8 and is located on its axis 9.

Elastic-damping elements 10 can be made in the form of cylindrical coil springs, the external helical surface of which is covered with vibration damping mastic, for example, type VD-17.

The filler may be made in the form of spherical chips of one diameter; in the form of spherical crumbs of different diameters. The filler can be made in the form of crumbs of arbitrary shape of different diametric (maximum external, arbitrary shape, contour of the crumb) size.

The explosion-proof panel operates as follows.

When an explosion occurs inside the production room (not shown in the drawing), the panel 1 rises from the action of the shock wave and overpressure is released through the open opening 8.

In this case, the elastic damping elements 10 are compressed, absorbing the energy of the explosion, and then return the panel to its original state.

The outer helical surface of the elastic damping elements 10 is covered with vibration damping mastic, for example, type VD-17, which further contributes to the damping of the blast wave.

After the explosion and the drop in excess pressure, dropping down, the panel closes the opening 8 and harmful substances do not enter the atmosphere. Stop plates 5 are used to fix the limit position of the panel. In order to damp (soften) shock loads when the panel is returned, the filler of the metal frame 1 is made in the form of a dispersed air-lead system, moreover, the lead is made in the form of a crumb, and the support rods 4 can be made elastic.

Using the proposed technical solution allows the prevention of explosive objects from destruction and the reduction of harmful substances into the atmosphere during an accidental explosion.
