A gas explosion-proof partition for underground

Abstract

The invention provides a gas explosion-proof partition plate for downhole. The gas explosion-proof partition plate comprises an explosion-proof partition plate body and a plurality of sets of unit bodies; each set of unit body comprises a base and a basic micro element structure matched with the base; the basic micro element structures are mounted into U-shaped bases to constitute U-shaped unit bodies, and the basic micro element structures are mounted into corresponding U-shaped structures of H-shaped structures to constitute H-shaped unit bodies; and in the length direction, the H-shaped unit bodies and the U-shaped unit bodies are alternately distributed, the U-shaped unit bodies are located in the middle, and the upper U-shaped unit bodies and the lower U-shaped unit bodies are symmetrically distributed at intervals, the two sides of the U-shaped unit bodies abut against the H-shaped unit bodies through first buffering rods, and the basic micro element structures in the U-shaped unit bodies make contact with the upper inner wall and the lower inner wall of a corresponding explosion-proof cavity. According to the gas explosion-proof partition plate for the downhole, explosion detonation wave is buffered and absorbed, firstly, the explosion detonation wave is blocked and buffered through a protecting plate, then energy is transmitted to foamed concrete, second rubber rods andceramic base structures in the explosion-proof partition plate body and consumed, and the buffering energy-absorbing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of gas explosion protection, and in particular relates to an underground gas explosion-proof partition. Background technique [0002] Gas is a mixed gas released from coal and rocks during coal mine production. The main component is methane, which is flammable and explosive. my country is a country with abundant coal resources. Although my country is rich in coal resources, the number of existing high-gas mines is also very large. This type of coal mine has a high explosion risk factor. Once a gas explosion accident occurs, it will damage property equipment and The safety of underground workers causes great harm. [0003] Explosion-proof doors for mines are mainly used to resist the shock waves generated when gas or coal seam explosions occur inside mine tunnels, and to prevent the fan from being damaged by the impact. When the gas explodes, this kind of explosion-proof door will be seriously deformed due t...

my country is a country with abundant coal resources. Although my country is rich in coal resources, the number of existing high-gas mines is also very large. This type of coal mine has a high explosion risk factor. Once a gas explosion accident occurs, it will damage property equipment and The safety of underground workers poses a great hazard

[0003] Explosion-proof doors for mines are mainly used to resist the shock waves generated when gas or coal seam explosions occur inside mine tunnels, and to prevent the fan from being damaged by the impact. When the gas explodes, this kind of explosion-proof door will be seriously deformed due to the impact of the explosion energy, and the anti-explosion and impact-proof effect is not very good. Therefore, it is necessary to install a portable explosion-proof partition with high energy-absorbing effect under the mine

[0004] Chinese utility model patent "An Explosion-proof Panel" (Patent No.: CN208441271U) discloses an explosion-proof panel, which is used to connect the explosion-proof panel more closely, including a fireproof panel and galvanized steel plates located on both sides of the fireproof panel. The galvanized steel plate on one side of the explosion-proof board is vertically provided with connecting plates; the first straight through hole and the second straight through hole which are perpendicular to each other and do not intersect each other are arranged in the fireproof board, and the first straight through hole The axis of the explosion-proof plate is parallel to the long side of the explosion-proof plate, and the axis of the second straight through hole is parallel to the short side of the explosion-proof plate; the explosion-proof plate designed by this utility model improves the explosion-proof structure composed of multiple explosion-proof plates. The overall explosion-proof performance of the system, but its structure is simple, and its ability to reduce impact energy and disperse and consume explosion impact energy is poor

[0005] The Chinese invention patent "A New Type of Explosion-proof Panel and Its Manufacturing Method" (Patent No.: CN109403539A) discloses a new type of explosion-proof panel and its production method, which includes a rectangular parallelepiped explosion-proof panel body. The main body of the explosion-proof panel includes a left panel, a right panel, The front panel, the back panel, and the support partition, the front panel and the back panel respectively constitute the front and back of the main body of the explosion-proof panel, the left panel and the right panel are respectively located at the ends of both sides of the explosion-proof panel body, and the left panel and the right panel are both connected to the explosion-proof panel body. The front panel and the back panel are connected by welding or bonding. The left panel, the right panel, the front panel and the back panel are surrounded to form a cavity. The partition divides the cavity into a left cavity and a right cavity. The left cavity and the right cavity are filled with light expanded vermiculite A and light expanded vermiculite B respectively. The through holes of expanded vermiculite A and lightweight expanded vermiculite B; this invention increases the impact resistance and fire resistance of the explosion-proof plate, and improves the explosion-proof performance of the explosion-proof plate, but it only uses filling in the left and right cavities Different lightweight expanded vermiculite, simple structure, general explosion-proof impact resistance
