Description
Technical field
The present invention relates to a kind of fire curtain.Belong to extinguisher technical field.
Background technology
Existing one " 3J type water storage combined type water smoke super fire resistant roller shutter " is (see Ministry of Public Security Sichuan fire-fighting Research Institute, " 3J type water storage combined type water smoke super fire resistant roller shutter " Products of Chengdu Co., Ltd of Hui great patent technical research institute), by rolling screen guiding rail, there is the roller shutter of curtain in curtain, containing alternating current generator, reducer, braking mechanism, electromagnetic clutch, hand chain wheel and control the electromechanical integration door-rolling machine of the control unit that power supply connects with fire-fighting, warming self-landing device, decline the travel switch that puts in place, be made up of the water smoke controller of solenoid control and waterfog head.When breaking out of fire, realized the decline of fire curtain by electromagnetic clutch or warming self-landing device release braking mechanism.Decline when putting in place and cut off the electricity supply by travel switch, electromagnetic clutch and braking mechanism reset and make fire curtain stopping descending.Water smoke is then connected water source to be formed by startup electromagnetic valve.By closed electromagnetic valve water smoke water source after fire is complete, starter motor or manually sprocket wheel make fire curtain rising reset.The shortcoming one of this fire curtain is its electromagnetic valve, electromagnetic clutch, alternating current generator use alternating current to control, and for ensureing its work, relevant regulatory requirements must two loop electrical network supports house generator, and wiring is many, and cost is large; Two is spraying requirements of continuous three hours for meeting regulations for fire fighting, need be energized for a long time, and power consumption is large.
Summary of the invention
The object of the invention is the shortcoming overcoming above-mentioned fire curtain, provide a kind of utilize existing fire-fighting control power supply control low cost, low power consuming energy-saving water mist fire curtain.
The formation realizing the energy-saving water mist fire curtain of the object of the invention comprises rolling screen guiding rail, there is the roller shutter of curtain in curtain, containing reducer, braking mechanism, relieving mechanism, the electromechanical integration door-rolling machine of hand chain wheel and control unit, warming self-landing device, decline the shut-down mechanism that puts in place, water smoke controller and the waterfog head of control valve are installed, it is characterized in that described relieving mechanism is arranged on two gunlocks on reducer shell by symmetry, the transmission ring being positioned at the striker stroke of gunlock be sleeved on the brake moved end of braking mechanism is formed, described warming self-landing device is arranged on the end of transmission ring, described decline put in place shut-down mechanism by be hinged on roller shutter decline fastening position and its moved end be connected with this pressing plate with one end higher than the radial type pressing plate of roller shutter decline fastening position, the other end touches with the striker of a drive link and transmission ring holds affixed flexible axle to form, and the control valve of described water smoke controller is by a ball valve and a direct current generator, be connected to the transmission mechanism between ball valve lever and DC motor shaft and be arranged on ball valve lever and lead to, the travel switch of disconnected position formed.
During use, the gunlock of this fire curtain, direct current generator are connected with the control unit in electromechanical integration door-rolling machine.Provide by control unit the direct current generator that the signal of telecommunication starts gunlock and water smoke controller during breaking out of fire, the striker action of gunlock drives the transmission ring be sleeved on the brake moved end of braking mechanism, and then driving brake moved end releases braking mechanism, roller shutter starts to decline.When roller shutter drops to close to when closing station, the bottom of roller shutter and the moved end of radial type pressing plate touch and then are pressed down the moved end of radial type pressing plate, the moved end of radial type pressing plate is moved downward around its twisted axis, while moving downward, be with the flexible axle be automatically connected on pressing plate to move downward, the motion of flexible axle then drives drive link to move and then drives transmission ring motion, the motion of transmission ring makes the striker of gunlock reset, roller shutter is braked thereupon resetting in the brake moved end of the braking mechanism of roller shutter, thus makes roller shutter stop declining.The running orbit of suitable design radial type pressing plate moved end and flexible axle, can be implemented in when station is closed in roller shutter decline and automatically stops.After the direct current generator startup of water smoke controller, the axis of rotation of motor, drives transmission mechanism and then drives the lever of ball valve to rotate toward opening direction, stop until touching travel switch power-off during ball valve full open position, thus connects water source realization spraying.After fire terminates, provide the signal of telecommunication by Fire Services Communication Centre, motor obtains electric rotating backward, and drives transmission mechanism and then drives the lever of ball valve to rotate toward closing direction, stop until touching travel switch power-off during the complete fastening position of ball valve, thus atomization mechanism is resetted close water source to stop spraying.The reset of roller shutter then manually sprocket wheel or come by such as existing patented product " battery operated fire-proof roll screen actuating device ".
Consider the roller shutter as just enabling when breaking out of fire, to twist at ordinary times on cylinder and to brake with braking mechanism, because stagnation is for a long time motionless, roller shutter cylinder by reasons such as dust viscous after causing releasing of brake mechanism roller shutter still can not start decline may, can install the descending starter of a roller shutter in the upper end of rolling screen guiding rail, the descending starter of described roller shutter is made up of the upper and lower sleeve be set in together and the Compress Spring be arranged in sleeve.The installation site of the descending starter of roller shutter ensures that the Compress Spring of roller shutter in non-fire station sleeve is in compressive state.Namely starter is applied with a downward spring force by the Compress Spring in sleeve to roller shutter.After the brake moved end releases braking mechanism of braking mechanism, the spring force release of starter, act on roller shutter bottom girder, thus it is descending to start roller shutter by lower sleeve.In roller shutter reseting procedure, the bottom girder of roller shutter, with horizontal reset on the lower sleeve of starter, makes the Compress Spring in sleeve be in compressive state.
Still can in curtain the hinged turnover panel in the lower end position place of curtain, at the two ends of turnover panel, one magnetic patch is set.The benefit done like this can be dug turnover panel fast and utilize the magnetic patch at turnover panel two ends to amplexiform in curtain sheet by turnover panel, formed the passage of fire hose with this.Fire hose still remains an entirety well by curtain in rear curtain and plays the effect cutting off the scene of a fire and pass in and out for related personnel with roller shutter.
Compared with prior art, advantage of the present invention eliminates electromagnetic valve that original use alternating current controls, electromagnetic clutch and alternating current generator, thus do not need to lay power line, greatly saved cost.The decline shut-down mechanism that puts in place of newly-designed mechanical type ensure that roller shutter drops to the automatic hold function of fastening position.Install the descending starter of roller shutter additional, improve the reliability of the passive automatic descending of roller shutter.Utilize fire-fighting to control power supply and do power, not only convenient easily control, and only need a seconds just can complete and keep connecting water source to realize spraying, energy consumption is reduced greatly.
Content of the present invention is further described with the following Examples.
