Abstract
The utility model relates to a mine fire-resistant roller shutter door, which comprises a roller, slide ways and a shutter plate. The mine fire-resistant roller shutter door is characterized in that: nets and fixing bars are connected together to form the shutter plate, each net is made of metal or composite material, the mesh density of each net is 210 to 250 meshes per centimeter, and the fixing bars are connected with and fix the nets, so that the roller can conveniently roll and unroll the shutter plate. When a fire happens, the mine fire-resistant roller shutter door is quickly put down, and by utilizing the flame-extinguishing gap principle, the mine fire-resistant roller shutter door can ensure that most of flames can be extinguished when the flame front passes through the nets of the mine fire-resistant roller shutter door, thus preventing the fire from further spread. Meanwhile, since the shutter plate of the mine fire-resistant roller shutter door comprises the nets, the ventilation of airflow is kept, consequently, the formation of a closed space is prevented, and the occurrence of the gathering and explosion of flammable gas is reduced. The structure of the mine fire-resistant roller shutter door is simple, and the mine fire-resistant roller shutter door is quick to use, and can timely stop the spread of the underground fire, thus gaining time for disaster fighting and emergency rescue.
Description
Technical field
The utility model relates to a kind of mining fire fighting equipment, a kind of mining fire insulation rolling door of more specifically saying so.
Background technology
Along with increasing of middle and small scale coal mine, the coal-mine fire accident happens occasionally, and the safety problem in colliery has more and more caused people's attention.At present, during the down-hole breaking out of fire, it is commonly used that to avoid fire spread and gas explosion measure be to pile up fire dam, this kind method build and demolishing process in, the preparation amount is big, high material consumption, enforcement required time are long, and can the formation confined space in the process of piling up and then cause more serious blast, staff's implementation and operation is relatively more dangerous, therefore, this method can not satisfy the needs of controlling the condition of a disaster quickly and effectively, can not provide rescue and relief for disasters and emergencies for mine and race against time.
Summary of the invention
The purpose of this utility model provides a kind of safe and reliable mining fire insulation rolling door, spreads to stop underground fire, prevents gas explosion.
The purpose of this utility model can realize in the following manner: mining fire insulation rolling door, constitute by spool, slide rail, curtain plate, its characteristics are: curtain plate is formed by connecting by wire side and fixed strip, wire side is made by metal material or composite material, the mesh density of wire side is every square centimeter 210～250 hole, fixed strip is used for connecting and fixing wire side, makes the instant rolled curtain plate of putting of spool.
In each tunnel of mine this mining fire insulation rolling door is installed, when mine is produced, mining fire insulation rolling door is opened, do not influence normal ventilation requirement; When fire takes place, put down this mining fire insulation rolling door rapidly, utilize gap flame arrest principle, most of flame is extinguished when making the wire side of flame front by mining fire insulation rolling door curtain plate.Be provided with in the mine laneway many places under the situation of mining fire insulation rolling door, can stop further spreading of fire, the curtain plate of this mining fire insulation rolling door is made of wire side simultaneously, the circulation that has kept air-flow, avoided the formation of confined space, reduce the fuel gas gathering, and then avoided the generation of confined space implode.
The utility model has following advantage:
1, overall structure simple, cheap, be convenient to the transportation, handling safety.
2, method of operating is simple, can in time stop spreading of underground fire, gains time for providing rescue and relief for disasters and emergencies.
3, curtain plate is ventilated, has avoided the generation of confined space implode.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is curtain plate partial enlarged drawings described in the utility model.
Among the figure: 1-spool, 2-slide rail, 3-curtain plate, 4-wire side, 5-fixed strip.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As follows with reference to accompanying drawing 1: fire insulation rolling door that the utility model is mining is made of spool 1, slide rail 2, curtain plate 3.Be with reference to accompanying drawing 2 mining its characteristics of fire insulation rolling door: curtain plate is formed by connecting by wire side 4 and fixed strip 5, wire side 4 is made by metal material or composite material, the mesh density of wire side 4 is every square centimeter 210～250 hole, fixed strip 5 is used for connecting and fixing wire side 4, makes the spool 1 instant rolled curtain plate 3 of putting.
In each tunnel of mine this mining fire insulation rolling door is installed, when mine was produced, this is mining, and the fire insulation rolling door was opened, and does not influence normal ventilation requirement; When fire takes place, put down this mining fire insulation rolling door rapidly, utilize gap flame arrest principle, most of flame is extinguished when making the wire side 4 of flame front by mining fire insulation rolling door curtain plate 3, be provided with in the mine laneway many places under the situation of mining fire insulation rolling door, can stop further spreading of fire, the curtain plate 3 of this mining fire insulation rolling door is made of wire side 4 simultaneously, the circulation that has kept air-flow, avoided the formation of confined space, reduce the fuel gas gathering, and then avoided the generation of confined space implode.
