Abstract
The invention discloses a portable emergency device for a coal-mining working face. The portable emergency device for the coal-mining working face comprises a main body, wherein the main body is integrally in a shape of a rectangular parallelepiped; a handle, an air generating device switch and a miniature gas consistency detecting device are arranged at the top of the main body; an air curtain and an air generating device are arranged inside the main body; side doors of which the thickness is equal to that of the air curtain are arranged on two sides of the bottom of the main body, wherein the air curtain comprises three layers which are a non-woven fabric air bag, an intermediate macromolecular fibrous layer and an outside-edge fireproof layer in sequence; the layers are connected in a gluing manner; connecting passages are arranged between the layers; the air generating device is connected with the air curtain through an air inflation passage on the non-woven fabric air bag. The portable emergency device for the coal-mining working face, which is provided by the invention, is simple and practical, can be rapidly unfolded in case of a sudden risk, obstructs flames, decreases explosive impact force, and is further provided with the gas consistency detecting device which reminds miners in time when the gas consistency rapidly rises or is too high, thereby avoiding the generation of the risk.
Description
The present invention relates to a kind of safety of coal mines device, in particular relate to a kind of portable emergency set of coal-face.
Demand recently as coal constantly changes and development, mine equipment also synchronize occur change, the supporting of coal mine working Middle face and the supporting of two ends and coal mine roadway has developed the rapidest with the problem of management, but the content that the weak link being also always during fully-mechanized mining working produces for the safety problem of miner in face with complex also needs emphasis to consider, great potential safety hazard will be brought without the instrument or urgent rescue measure keeping away calamity easily when in the face of certain danger, also family can be given, society and country bring inevitable disaster.Protection at large-scale Environment of Mine Disaster has been achieved for gratifying achievement in terms of improvement, but still suffers from certain shortcoming for local, the improvement of disaster miniature, unexpected.
It is an object of the invention to provide a kind of portable emergency set of coal-face, its simple in construction, easy to use, to solve the problem of proposition in above-mentioned technical background.
To achieve these goals, the technical solution of the present invention is: the portable emergency set of coal-face, including: main body, wherein main body is the most rectangular-shaped, body top includes handle, gas generating unit switch and Miniature gas concentration detection apparatus, body interior includes gas curtain and gas generating unit, and bottom part body both sides have and the side door of gas curtain equal thickness.
The portable emergency set of coal-face of the present invention, wherein, described gas curtain comprises three layers, it is followed successively by non-woven fabrics air bag, middle macromolecular fibre layer and outer fireprotection layer, gluing connects and is provided with interface channel between layers, is dispersed with the filling channel of a series of intersection, gas generating unit and gas curtain and is connected by the filling channel intersected on non-woven fabrics air bag, in gas generating unit, it is built-in with Hydrazoic acid,sodium salt or ammonium nitrate.
After using such scheme, coal-face of the present invention is simple and practical with portable emergency set, can launch rapidly when in the face of certain danger, intercept flame and reduce blast impulse force, methane Concentration Measurement device is additionally provided, give miner in time to remind when gas density raises rapidly or be too high, it is to avoid dangerous generation.The method of coal-face flexible air-bag of the present invention closure corner, is fixed on flexible air-bag on individual prop owing to first arranging individual prop again, and therefore closure efficiency is high, effective, and realizes mechanization closure, reduces the labor intensity of workman.
Fig. 1 is the portable emergency set structural representation of coal-face of the present invention；
Fig. 2 is that the portable emergency set of coal-face of the present invention launches front view；
Fig. 3 is that the portable emergency set of coal-face of the present invention launches rearview；
Fig. 4 is the portable emergency set side view of coal-face of the present invention.
Refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the portable emergency set of coal-face, including: main body 1, wherein main body 1 is the most rectangular-shaped, main body 1 top includes shaking hands 13 being available for users in carrying process lifting, gas reaction device switch 11 and Miniature gas concentration detection apparatus 12, give miner in time to remind when miner site gas density raises rapidly or be too high, in order to take corresponding measure, it is to avoid dangerous generation；Main body 1 is internal includes gas curtain 2 and gas generating unit 3；Gas curtain 2 comprises three layers, respectively is non-woven fabrics air bag 21, middle macromolecular fibre layer 23 and outer fireprotection layer 24, and gluing connects and is provided with interface channel between layers；Wherein it is dispersed with the filling channel 22 of a series of intersection on non-woven fabrics air bag 21, middle macromolecular fibre layer 23 can absorb the huge impulse force that explosion time produces, reduce the blast harm to miner, outer fireprotection layer 24 can temporary obstruct flame, reducing fire and to miner and the harm on trade and increase rescue time, gas generating unit 3 and gas curtain 2 are connected by the filling channel 22 on non-woven fabrics air bag 21；Main body 1 two bottom sides has and the side door of gas curtain 1 equal thickness；In use; user is by pressing gas generating unit switch 11; it is built in the Hydrazoic acid,sodium salt of gas generating unit 3 at short notice will to decompose rapidly reaction produce a large amount of gas and make non-woven fabrics air bag 21 middle macromolecular fibre layer 23 and outer fireprotection layer 24 are full of by gas successively along filling channel 22 on non-woven fabrics air bag 21 and then be pushed out main body 1 along the side door of main body 1 two bottom sides with gas curtain equal thickness to launch, quickly forms one side multilamellar and meet an urgent need protecting wall thus serve life security and the increase rescue time of protection miner.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention determines.
