Description

A kind of fire prevention door equipment of use in passageway for fire apparatus
Technical field
The present invention relates to a kind of firebreak device, and in particular to a kind of fire prevention door equipment of use in passageway for fire apparatus.
Background technology
Rolling screen door is cascaded with the door piece of multi-joint activity, in fixed slideway, in being with door top spool The heart rotates upper and lower door.Rolling screen door equally plays horizontal subdivision with the effect of wall, it by curtain plate, seat board, guide rail, bearing, spool, 13 parts such as casing, control cabinet, door roller, limiter, lintel, button switch and safeties constitute, and are typically mounted at not Just the position for being separated using wall.Rolling screen door is applied to the public places such as the business shop front, garage, market, hospital, industrial enterprise or lives Residence.Especially door opening is larger, and convenient, fast unlatching effect is played in the place that ground door body is installed in inconvenience;The structure of fire resistance rolling shutter door Make.Fire resistance rolling shutter door is made up of the part such as curtain plate, coil body, guide rail, Electrified Transmission.Curtain plate is that 1.5 cold-strip steels for deleting thickness roll It is made " C " template, overlaps interlocking, with good rigidity, the characteristics of sealing property is excellent.
Traditional protective rolling curtain door is mainly the effect of warning of blowing a whistle, when really there is fire, it is impossible to play the work of fire extinguishing With, but all of fire is all that from small to large, if can be put out a fire in the very first time, may will lack a great calamity, institute Want one kind to blow a whistle with our urgent needs and warn fire prevention, and can also the interior fire resistance rolling shutter door put out a fire of certain limit.
The content of the invention
The technical problems to be solved by the invention are that rolling screen door can not only blow a whistle warning fire prevention, and can also be in certain limit Fire extinguishing, it is therefore intended that a kind of fire prevention door equipment of use in passageway for fire apparatus is provided, solution rolling screen door can not only blow a whistle and warn fire prevention, And can also the interior problem put out a fire of certain limit.
The present invention is achieved through the following technical solutions:
A kind of use passageway for fire apparatus fire prevention door equipment, including rolling screen door, be arranged on roller shutter power transmission shaft in rolling screen door, Dry powder devices and Smoke Sensor, and, switching device:Send opening or close command to central processing unit;The smog is passed Sensor:Smog information in the range of acquisition testing, sends to central processing unit;The central processing unit:Receive switching device hair The opening or close command sent, send instruction to motor of opening the door or close the door;The smog information of Smoke Sensor is received simultaneously, The preferential smog information for performing Smoke Sensor, is contrasted with preset value, during beyond preset value, alarm is sent to warning device Instruction, sends fire extinguishing and closes the door instruction to motor, and sending fire extinguishing to Dry powder devices instructs;The motor:Receive center Enabling or instruction of closing the door that processor sends, drive roller shutter power transmission shaft to turn clockwise or turn counterclockwise;Receive central processing unit Fire extinguishing is closed the door instruction, drives roller shutter power transmission shaft to turn clockwise, and when rolling screen door lower section is apart from 1.5 meters of ground, motor control is rolled up Curtain power transmission shaft turns underdrive clockwise;The roller shutter power transmission shaft:Rolling screen door top is connected to, the closure of rolling screen door is can control; The warning device:The alarm command of central processing unit is received, alarm is sent;The Dry powder devices:Receive central processing unit Fire extinguishing instruction, when rolling screen door lower section is apart from 1.5 meters of ground, control jet hose work.Traditional protective rolling curtain door mainly rings The effect of flute warning, when really there is fire, it is impossible to play a part of fire extinguishing, but all of fire be all from small to large, If can be put out a fire in the very first time, may will lack a great calamity, so we be badly in need of want one kind can not only blow a whistle warning prevent Fire, and can also in certain limit fire extinguishing fire resistance rolling shutter door, the present invention is provided with Dry powder devices in rolling screen door, can pass through Dry powder devices are put out a fire, and solve the deficiency of conventional door.
Also include range sensor in the rolling screen door, range sensor detection rolling screen door lower section apart from ground away from From and send to motor and Dry powder devices, range sensor detection range so that 1.5 meters is later slowly to close the door, this It is to be withdrawn to provide the time to evacuation personnel, specific deceleration can be by setting.
The switching device includes remote control switch and manual push button switch, two kinds of on-off modes, it is to avoid simply opened with one kind Influence work is damaged caused by closing, two kinds of probabilities for damaging simultaneously greatly reduce.
The warning device, using in voice alarm, flashing light alarm, alarm of blowing a whistle any one.According to the scene for using To set the pattern of alarm.
The present invention compared with prior art, has the following advantages and advantages:
1st, in the fire prevention door equipment of passageway for fire apparatus, Dry powder devices can be gone out by Dry powder devices for a kind of use of the invention Fire, solves the deficiency of conventional door;
2nd, a kind of use of the invention passageway for fire apparatus fire prevention door equipment, range sensor detection range so that 1.5 meters with After be slowly to close the door, this is withdrawn to provide the time to evacuation personnel, and specific deceleration can be by setting;
3rd, a kind of use of the invention passageway for fire apparatus fire prevention door equipment, two kinds of on-off modes, it is to avoid simply opened with one kind Influence work is damaged caused by closing, two kinds of probabilities for damaging simultaneously greatly reduce.
