Abstract

The utility model relates to an electromechanical controlling device. The lower end of an impact plate is connected with a roller shutter shaft, and is also fixed with a connecting rod of which one end is used for supporting a raising rod which is contacted with a power push-button switch of a radio emitter. The normally open contact of a relay which is arranged in a maneuvering box and is driven by a receiver is connected with a rising button or a falling button in parallel. The rising and the falling push buttons provided by a smoke detection and temperature detection signal processing circuit of an electric control box controls a level to start a motor through a monostable circuit for rising running of the roller shutter, and the inverse output of the monostable circuit can start the motor for falling running of the roller shutter. The utility model has simple control structure for both machinery and the circuit, and provides a conveniently operated and reliable emergency measure for escape and fire-fighting operation.

Description

Fire resisting shutter promptly promotes control device

The utility model belongs to control device, relates to the urgent electromechanical controlling device that promotes of a kind of fire resisting shutter.

Existing fire resisting shutter falls control by cigarette sense signal and temperature sense signal two steps of work respectively usually closes roller shutter, the roller shutter of closing fully can only not had time-delay rising control by the rising button of maneuver box, the problem of bringing thus is: under the fire condition, if still have the personnel of disengaging in time in the zone of being covered by roller shutter envelope, under extremely alarmed and smoke condition, very difficult searching maneuver box is also accurately pressed the rising button and can't be escaped danger; The rising control of not having time-delay will seriously hinder the fire extinguishing operation, unless push the rising button by the special messenger.

The purpose of this utility model provides a kind of fire resisting shutter of being convenient in time to escape danger and putting out a fire and promptly promotes control device, to improve the performance of fire resisting shutter.

Above-mentioned purpose is realized by following technical scheme: shock plate 6 lower ends are connected with roller shutter 1 bottom axle, also fix the connecting rod 7 that an end supports raising rod 5 simultaneously, promoting extension bar 5 contacts with the power supply button switch 3 of wireless launcher 4, be located at the relay J in the maneuver box 10 by the receiver driving, its normally opened contact and rising button or decline button are in parallel, the rising that the cigarette sense of electric cabinet 9, temperature sense signal processing circuit provide, decline button control level are done roller shutter rising running through monostable circuit DW starter motor, and monostable anti-phase output starter motor is done roller shutter decline running.

Wireless launcher 4 is fixed in roller shutter 1 by its housing 2, and housing is provided with the spacing slotted hole 8 of raising rod 5;

The fire alarm sound light alarming circuit E that the control level that being equipped with in the maneuver box 10 is provided by cigarette sense, temperature sense signal processing circuit or fire-fighting center starts;

Its K switch of electronic lock on the maneuver box 10 S provides manual control level for rising, decline button.

The utility model has the advantages that: machinery and circuit control structure are simple, for escaping danger and the operation of putting out a fire provides the emergency measure of convenient and reliable operation.

Below with drawings and Examples explanation the utility model.

Accompanying drawing 1, mechanical control structure schematic diagram of the present utility model;

Accompanying drawing 2, Figure 1A-A view;

Accompanying drawing 3, the utility model electrical schematic diagram.

1 roller shutter among the figure, 2 housings, 3 power supply button switches, 4 wireless launchers, 5 raising rods, 6 shock plates, 7 connecting rods, 8 slotted holes, 9 electric cabinets, 10 maneuver boxs.

As shown in Figure 1, rely on raising rod 5 deadweights, position such as Fig. 2 of raising rod and shock plate 6, when on carry raising rod or make shock plate stressed in the direction of arrows, then raising rod moves up in slotted hole 8, closes with the power supply button switch 3 of the wireless launcher 4 that contacts and closes.

The course of work of the present utility model is seen Fig. 3, when fire takes place, the output of the cigarette sense signal processing circuit C of electric cabinet 9 is warp or door D14 at first, D13, make and door D1, D2 one input is a high level, make the rising and the decline button KN1 of maneuver box 10 simultaneously, KN2 has obtained high level, if two buttons and raising rod attonity, then with door D1, D2 is output as low level, monostable circuit DW does not overturn, its output is after NAND gate D8 is anti-phase, through making motor-drive circuit B work with door D9 or door D11, motor is done roller shutter decline running, stops stop KZT in the collision midway, and then motor shuts down, treat that temperature sense signal processing circuit D has output warp or door D15, D12 reaches with a door D9 or a door D11 and makes motor continue the decline running, finishes two steps of roller shutter and falls action.

In the roller shutter decline process or descend and to finish, move the wireless launcher work that makes on the raising rod, then the receiver in the maneuver box 10 will make the relay J action, be connected on rising arbitrarily, decline button AN1, the normally opened contact adhesive at AN2 two ends, for example be connected the AN1 two ends among the figure, then be output as high level with door D1, monostable circuit DW is triggered, by or door D10 and motor-drive circuit A to make the motor antiport be that roller shutter rises, its rise time is determined by monostable DW time constant, for example rises 20 seconds, and delay time is to then monostable DW recovery, motor-drive circuit A, B switches mutually, and roller shutter is done the operation that descends.

When fire took place, cigarette, temperature sense signal warp or door D13 made the fire alarm sound light alarming circuit E work that is located in the maneuver box 10, utilized acousto-optic to trapped personnel prompting maneuver box position, can press arbitrary button arbitrarily and make roller shutter finish above-mentioned uphill process.

Maneuver box provides operation level by its K switch of electronic lock S of key control for rising, decline button, under the situation of no fire, by controlling motor-drive circuit A or B with door D4, D3, handles the roller shutter rising or descends and move.

The wireless launcher of present embodiment and receiver adopt YYH26, YYH27 integrated circuit and corresponding components and parts to form, and this integrated circuit that uses is provided with the coding of phase thing in pairs, to prevent the misoperation of adjacent roller shutter.

Use the utility model to spray or kick shock plate with giant, also can realize its function by portable raising rod, maneuver box and the mechanical controller structure of this device except that electric cabinet respectively established a cover outside all in roller shutter, does identical electrical connection with electric cabinet.
