Abstract
A coal mine underground foam explosion-proof trough relates to a coal mine underground gas and smut explosion-isolating device. The disclosed technique is that a right grooved wallboard (1) and a left grooved wallboard (3) are respectively arranged on the upper end faces of the two length sides of a rectangular bottom grooved wallboard (5), while a rear grooved wallboard (2) and a front grooved wallboard (4) are respectively arranged on the upper end faces of the two width sides; and the upper end faces of the right grooved wallboard (1), the rear grooved wallboard (2), the left grooved wallboard (3) and the front grooved wallboard (1) are provided with protruded circle edges (6). The coal mine underground foam explosion-proof trough has the advantages of simple and compact structure, as well as easy production and installation; compared with the isolated blast water bottle, the foam explosion-proof trough is larger in capacity and less in installation amount, which is fragile and can form good water fog to ensure good flameproof effect.
Description
One, technical field
The utility model relates to isolated gas and dust explosion device under the coal mine, foam flame proof tank under especially a kind of coal mine.
Two, background technology
At present, the colliery generally isolated blast water bottle of usefulness makes of the air duct cloth that contains muscle cloth, colludes on one side rely on blast pressure that water bag is taken off, and forms water mist body, puts out explosive flame.Because water bag is by a plurality of hook suspension hooks, on-the-spot in addition hook angle is inconsistent or hook is too dark, causes actual unhook bad, influences water bag water smoke and forms, and is difficult to guarantee the flame proof effect of isolated blast water bottle.
Three, summary of the invention
In order effectively to prevent the gas and dust explosion propagation, isolated gas and dust explosion need be a kind of easy for installation, guarantees the flame proof measure of flame proof effect, for Safety of Coal Mine Production provides safety guarantee.The purpose of this utility model provides a kind of simple in structure, can effectively prevent gas explosion in underground coal mines, ensures miner's the comparatively ideal explosion isolation device of personal safety, i.e. foam flame proof tank under the coal mine.
The technical scheme that the purpose of this utility model adopted is, form by right cell wall plate, pit wallboard, left cell wall plate, preceding cell wall plate, kerve wallboard, its upper surface, two long limits that is the kerve wallboard of rectangle has right cell wall plate and left cell wall plate, two broadside upper surfaces that pit wallboard and preceding cell wall plate are arranged respectively respectively, outstanding platform is arranged along the circle limit in the upper surface of right cell wall plate, pit wallboard, left cell wall plate and preceding cell wall plate.
The utility model, it is trapezoidal that right cell wall plate is isosceles.
The utility model, it is trapezoidal that the pit wallboard is isosceles.
The utility model, it is trapezoidal that left cell wall plate is isosceles.
The utility model, it is trapezoidal that preceding cell wall plate is isosceles.
Horizontal embedding of the utility model or pop-up are full of water on two crossbeams of tunnel, rely on the pressure of blast to smash or the flame proof tank of throwing, and form water smoke to put out and isolated coal mine gas coal-dust explosion propagating flame guarantee national wealth and miner's personal safety.On crossbeam, set gradually several foam flame proof tanks according to the needs under the coal mine by required separation distance.
Flame proof principle of the present utility model: the gas and dust explosion propagation test that in large-scale groundwater simulation testing gallery, carries out, gas and dust explosion pressure and law of flame are that at the blast initial stage, flame propagation velocity is greater than pressure-wave emission speed, flame is preceding, the pressure crest after; Along with the development of blast, compression wave speed increases, and surpasses flame propagation velocity, and during apart from the 40m left and right sides, quick-fried source, compression wave is caught up with and surpassed flame; Along with the increase of distance, the leading flame of compression wave is more and more far away.According to above-mentioned principle, foam flame proof tank will form water smoke, must rely on the effect of blast pressure to smash or the foam flame proof tank of throwing.
The utlity model has simple and compact for structure, fabrication and installation conveniently than the isolated blast water bottle capacity big, it is few, frangible that quantity is installed, it is good to form water smoke, guarantees characteristics such as flame proof is effective.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model perspective view;
Fig. 2 is Fig. 1 cross section sectional structure schematic diagram.
Among the figure: the outstanding platform of the preceding cell wall plate 5-kerve wallboard 6-of cell wall 3-left side cell wall plate 4-is along the circle limit behind the right cell wall plate of the 1-2-
Five, the specific embodiment
As shown in Figure 1 and Figure 2, form by right cell wall plate 1, pit wallboard 2, left cell wall plate 3, preceding cell wall plate 4, kerve wallboard 5, its upper surface, two long limits that is the kerve wallboard 5 of rectangle has right cell wall plate 1 and left cell wall plate 3, two broadside upper surfaces that pit wallboard 2 and preceding cell wall plate 4 are arranged respectively respectively, outstanding platform is arranged along circle limit 6 in the upper surface of right cell wall plate 1, pit wallboard 2, left cell wall plate 3 and preceding cell wall plate 4.It is trapezoidal that right cell wall plate 1 is isosceles.It is trapezoidal that pit wallboard 2 is isosceles.It is trapezoidal that left side cell wall plate 3 is isosceles.It is trapezoidal that preceding cell wall plate 4 is isosceles.
The utility model material is polypropylene (be called for short PP) or acrylonitrile-butadiene-styrene (being called for short ABS), adds fire-retardant, antistatic additive, with the mould one-shot forming of foaming.Satisfy the requirement of safety regulations in coal mine to the colliery plastic products.
