Description

Automatic controlling device for flameproof rolling door

The utility model relates to a kind of control device that fire resistance rolling shutter door moves in accordance with regulations of controlling when the condition of a fire takes place.

The control device of existing fire resistance rolling shutter door, it mostly is hand, as at present widely used by (the Hebei Zhijiang county) Chinese People's Liberation Army the 4820th plant-manufactured " door-rolling machine electric control box ", main composition comprises two button boxes and a Main Control Tank that is made of relay, contactor, realizes the keying operation of rolling door by the manually-operated button box.In order to prevent the non-relevant personnel's maloperation, normally be locked in the can at ordinary times, can not find the key implementation and operation when often causing breaking out of fire and can not get timely processing.Moreover this class control device adopts relay, contactor to serve as executive component, by contact action, fault rate height.Its another deficiency is that function is poor, can't with the fire alarm control system networking operation, do not reach of the requirement of national relevant clauses to the working procedure of fire resistance rolling shutter door.

The purpose of this utility model is intended to overcome the above-mentioned deficiency of existing rolling door control device, provide a kind of multiple functional, reliability is high, can satisfy the fire curtain door automatic control device that regulation requires.

The formation of fire curtain door automatic control device of the present utility model comprises that two are the button box and that is connected in parallel and are connected Main Control Tank between button box and the rolling door drive motors, Main Control Tank has the electrification reset start-up circuit, postpones the driving rolling door rising of timing circuit and two self-lockings each other, rising drive circuit and the decline drive circuit that descends, described button box is provided with and switches connection formula switch, the electrification reset start-up circuit has an outer signal input interface, and its output also is connected to an audible-visual annunciator.Two button boxes are installed in the place of being convenient to operate of the inside and outside both sides of rolling door respectively during use, the drive circuit output termination rolling door drive motors of Main Control Tank, the outer signal input interface and the Fire Services Communication Centre of electrification reset start-up circuit join, and external power source inserts Main Control Tank.When the condition of a fire takes place, signal enabling control device work from control centre, audible-visual annunciator sends sound and light alarm, postpone timing circuit and carry out following function: when rolling door is in upper position by the present position of rolling door at that time, postpone timing circuit and trigger the decline drive circuit works, rolling door is descended, continue to drop to least significant end again after making a brief stay when dropping to certain position and close rolling door, feedback signal is to the fire-fighting center simultaneously; Simultaneously, when upper position, realize the manual priority function, two buttons recover crawl function separately.When rolling door is in lower position, realize the escape priority function, operate upper and lower button and all can trigger the rising drive circuit works, and realize the circuit self-insurance, automatically descend again after making rolling door rise to the certain position place to make a brief stay and close, feedback signal is to Fire Services Communication Centre simultaneously.

Described rising, decline drive circuit can be made of photoelectric isolating driving circuit and phse conversion circuit, by the change realization motor counter-rotating of phase place.On the rolling door stroke, set up upper end limit switch and lower end limit switch and insert drive circuit, can be implemented in risings simply, the automatic disconnection motor power when putting in place that descends, protect motor.

The count display that is connected in parallel, also flip-flop number display work when control device is started working can be write down the time that the condition of a fire takes place.

Can also connect as the signal transducer of cigarette dependent sensor, temperature pick up class and serve as the triggering signal of electrification reset start-up circuit, improve automaticity of the present utility model.

The utility model designs and produces by relevant laws and regulations requirement, has adopted contactless logic circuit, has reliable in action, and is multiple functional, and the advantage of automaticity height can be used in various fire resistance rolling shutter doors.

Provide embodiment below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the logic schematic diagram of present embodiment

Fig. 3 is the circuit diagram of present embodiment

Fig. 4 is the button box schematic diagram

Shown in Fig. 1～4, in the present embodiment, the electrification reset start-up circuit is made up of integrated circuit U8, U27, resistance R 1, R2, capacitor C 1, C2 and button, and it is controlled by button and Fire Services Communication Centre; The optional electric lock of using of switch is connected in switching, constitutes manual, automatic control management with button box, and its concrete formation comprises integrated circuits such as U29, U27, U3, U30 and U8; The rising drive circuit is made of rising button SA and integrated circuit U1, U2, U3, U6, U8, U9 and upper end limit switch K1; The decline drive circuit is made of decline button XA and integrated circuit U8, U9, U5, U3, U2, U1 and lower end limit switch K2; Postponing timing circuit is made of integrated circuit U8, U10, U15, U13, U25, U22, U12, U23 and position switch K3, described position switch K3 can be set in 1.5～1.8 meters by laws and regulations requirement, it postpones the timing performance and can set on request, K3 is made as 1.8 meters height in the present embodiment, and the delay timing is set at 5 seconds, timing in 60 seconds.Wherein, timing in 5 seconds is finished by U12, U23, U10, U25, and timing in 60 seconds is finished by U1, U11, U19.Audible-visual annunciator can adopt existing product, also available 556,557 integrated circuits and indicator lamp 7, and loudspeaker 8 constitute.Lamp and loudspeaker can be installed in the button box 3.Photoelectric isolating circuit and phse conversion circuit are made of U22, U27, U17, U13, U25; Timing display is made of U25, U18, U14, U24, U28 and 7 sections decoding circuit U31, U32, U33, U34 and LED nixie displaies 4, and the annexation between each original paper and integrated circuit as shown in Figure 3.When no fire signal, electronic lock are in " manual control " position, can be used for the rising of crawl control rolling door and decline and to the noise elimination of loudspeaker; When being in " automatic control " position, button can not be controlled the rolling door action; When receiving the signal of telecommunication that Fire Services Communication Centre 5 sends here, no matter which kind of position electronic lock is in, Main Control Tank all can be by following situation work: when rolling door more than 1.8 meters the time, make rolling door begin to descend, dropping to 1.8 meters stops and continues to drop to least significant end after 60 seconds and close rolling door, cut off motor power, simultaneously to the fire-fighting center feedback signal of telecommunication.When rolling door more than 1.8 meters the time, but also hand crawl rising button makes rolling door rise to any position.When rolling door is in 1.8 meters during with upper/lower positions, any one in the manual upper and lower button all can make rolling door rise to 1.8 meters and stop to descend automatically after 5 seconds again and close.Photoelectricity is isolated and drive circuit is realized the interchange 380V power supply of rolling door motor is controlled, and when the needs rolling door rose, drive circuit made machine operation under A, B, C three-phase alternating current state; When the needs rolling door descended, another drive circuit made machine operation under B, A, C three-phase alternating current state, made two drive circuits can not be in driving condition simultaneously by circuit control.For guaranteeing motor forward and backward dynamic response, set a delay timing in 2 seconds, promptly spreading after 2 seconds in rising or decline button, another button just works.
