RU188080U1 - EXPLOSION PROTECTIVE VESSEL - Google Patents

Abstract

The utility model relates to mining, namely, safety during mining, and can be used to localize explosions of gases and dust and gas mixtures in mine workings. The technical result of the utility model is to reduce labor costs and time to remove water or other explosion-proofing from the vessel compositions without preliminary manual removal from the supporting element. A vessel 1 for explosion-proof barrier is proposed, which is divided in the middle part by transverse seams into two pockets. A feature of the design of the vessel is the presence of a two-level arrangement of holes 5 for pouring water and holes with nozzles 9 with plugs, the removal of which allows you to drain the water from the pockets of the vessel 1 before removing it from the supporting element 2 together with the rod 3 and hooks 4.

Description

The utility model relates to mining, namely, safety during operations, and can be used to localize explosions of gases and dust and gas mixtures in mine workings using water or other explosive-containing compounds (inert dust, flame retardant solutions).

A known vessel for water barriers, containing an elastic shell with sealed pockets and holes for pouring water, as well as a device for mounting the shell on a rigid support. The device is made in the form of a pipe made of an elastic material located in the middle of the shell between the pockets. In this case, the pipe is formed from the material of the shell by connecting its walls with two seams (utility patent No. 47974, class E21F 5/00, published September 10, 2005, Bull. No. 25).

Under the action of the explosion, the elastic shell collapses, and the water contained in the vessels forms an aerosol cloud, which provides the quenching of the thermal and kinetic energy of the shock wave. Compared to barriers made of rigid troughs, a barrier with vessels made of elastic material has a higher protection efficiency, and water does not evaporate from it.

A significant drawback of the known vessel designs is the difficulty of removing water or other explosive-containing compositions from them when replacing them or transferring the screen as a whole.

Partially this drawback is eliminated in the explosion-proof barrier, including elastic vessels made of synthetic hoses, the opposite ends of which are connected with the eyes and hooks and to the supporting element with the possibility of disconnecting any of them (utility model patent No. 866662, class E21F 5/00 , published September 10, 2009, Bull. No. 25).

The possibility of separation from the attachment point to the support element allows one side to be lowered to the soil of the working formation and to remove water or another explosive-containing composition from the vessel through the filler holes.

A disadvantage of the known vessel, adopted as a prototype, is the complexity of the work, due to the manual removal, lowering and retention of the container with 40 l of water.

The technical result of the utility model is to reduce labor costs and time for removing water or other explosive-containing compositions from the vessel without first manually removing it from the carrier element.

A vessel for an explosion-proof barrier in the form of a sleeve of elastic material, divided in the middle by transverse seams into two pockets with a two-level hole arrangement, is proposed. The seams are made by high-frequency welding.

The difference is that the pockets on the end parts are equipped with holes made in the form of pipes with plugs, the opening of which ensures the removal of water from both pockets.

The essence of the utility model is illustrated by the drawing, where in FIG. 1 shows the position of the vessel in the cross section of the working, FIG. 2 - section 1-1 of FIG. 1, in FIG. 3 shows the assembly of the suspension of the vessel to the carrier beam.

The vessels 1 of the explosion-proof barrier are made of an elastic sleeve, and they are hung on the supporting element 2, which may have a rectangular or circular cross-section. For hinge use a rod or pipe 3 and hooks 4. Hooks 4 can have different lengths to adjust the height of the suspension of the vessels, taking into account their horizontality and the standard distance to the roof of the output.

For pouring water or filling the powder composition, the vessel has holes 5 with plugs 6, which can be used with adhesive tape, film petals, and others. The second suspension line is formed using transverse seams 7 in the walls of the vessel 1. When welding the design of the vessel, a transverse channel is formed 8, which is used to pass the rod or pipe 3.

Removing the plugs from the nozzles 9 makes it possible to remove water or another explosion-proofing composition from the vessel under its own weight. An empty vessel 1 with a pipe 3 is transferred to the supporting elements of another barrier.

Claims (1)

The vessel for the explosion-proof barrier in the form of a sleeve of elastic material, divided in the middle by transverse seams into two pockets with a two-level arrangement of holes, characterized in that the pockets in the end parts are provided with holes made in the form of nozzles with plugs, the opening of which ensures the removal of water from both pockets.
