Abstract

The utility model relates to a multi-functional automatic fireproof shutter which can automatically cut off fire behavior and the passages in which smoke spreads along wind pipes in high reliability and with various functions and self-check performance. The utility model comprises slates of shutter. A fireproof valve and a corresponding electric actuator for controlling the fireproof valve are arranged behind the slates of shutter. The electric actuator measures temperature by a temperature sensor. The electric actuator drives the fireproof to open or close by a drive gear and is connected with the central controller of a control center by a wire. A zinc-plated wire netting and a micro-perforated plate muffler are arranged between the slates of shutter and the fireproof valve.

Description

Multi-functional full-automatic fire shutter

The utility model relates to a kind of multi-functional full-automatic fire shutter of locating at the transformer station that Smoke prevention, fire protection requirement are arranged, subway passage, civil air defense constructions and installations, underground parking field system etc. of being used for.

In the background technology, existing firebreak device adopts fire resisting damper, and function singleness only has fire-proof function.In addition, its control device adopts the fuse sheet controller, and reliability is relatively poor, and the utmost point is not easy at ordinary times equipment be carried out self-examination.

The purpose of this utility model is to overcome the weak point in the background technology, provides a kind of multi-functional full-automatic fire shutter, when fire takes place, it can cut off the passage that the intensity of a fire and flue gas spread along airduct, reliability height, diverse in function automatically, can automatically reset, and can carry out self check.

For achieving the above object, the technical solution that the utility model adopts is as follows:

A kind of multi-functional full-automatic fire shutter, its special character is: comprise blade of louver window, the blade of louver window rear portion is provided with the YE of fire resisting damper and the switching of control corresponding fire resisting damper, and YE adopts memory temperature sensor thermometric.

Above-mentioned YE can be connected by lead with the central controller of control centre.

Above-mentioned YE can drive fire-protection valve by travelling gear and open and close.

Can be provided with wire gauze and silencing apparatus between above-mentioned blade of louver window and the fire resisting damper.

Above-mentioned wire gauze can be a galvanized wire mesh, and silencing apparatus can be a micro-perforated plate muffler, adopts flap resistance noise reduction structure, is made up of microwell plate, noise elimination cotton and twine.

Above-mentioned blade of louver window can be the rainproof blade of invagination formula.

Number in the figure is described as follows:

1-blade of louver window, 2-galvanized wire mesh, 3-micro-perforated plate muffler, 4-fire resisting damper, 5-YE, 6-motor, 7-driving gear, 8-travelling gear, 9-travelling gear, 10-output shaft gear, 11-memorial alloy.

Below in conjunction with accompanying drawing the utility model is described in further detail: referring to Fig. 1, Fig. 2, Fig. 3, the utility model ecto-entad constitutes the quaternity structure by blade of louver window 1, galvanized wire mesh 2, micro-perforated plate muffler 3 and fire resisting damper 4 successively, be provided with full-automatic electric actuator 5 in the fire resisting damper 4, YE 5 adopts Pu Luomi memory temperature sensor thermometric, when the breaking out of fire environment temperature was increased to 70 ℃ (or 280 ℃), the memory temperature sensor was that (or opening) fire resisting damper 4 is closed in the command execution unit action.Referring to Fig. 4, folded structure in blade of louver window 1 adopts can play waterproof action.In addition, adopt galvanized wire mesh 2 can play the protection against rodents effect, micro-perforated plate muffler 3 plays the noise elimination effect, adopts flap resistance noise reduction structure, is made up of microwell plate, noise elimination cotton and twine.Referring to Fig. 5, motor 6 drives driving gear 7 motions, and driving gear 7 drives output shaft gear 10 motions by travelling gear 8 and travelling gear 9 successively, drives motor operated valve and opens and closes.Referring to Fig. 6, Fig. 7, YE 5 is connected with the central controller of control centre by lead, and is provided with " the electronic K2 of opening ", " electronic pass K1 " key and corresponding indicator lamp and is wired to central controller.Fire-protection valve 4 is in normally open at ordinary times, when the condition of a fire takes place, can electronicly close, and also can and close by memorial alloy 11 full expansion shake-up microswitches, and the fire prevention temperature can be set according to actual needs.Press " the electronic K2 of opening ", " electronic pass K1 " button of being located at central controller, by corresponding indicator lamp, can monitor the duty of fire-protection valve 4, and the performance of YE carried out self check, concrete operations are as follows: by " the electronic K2 that opens " key, " opening indicator lamp " should be shinny immediately, transmission mechanism moves immediately, after arriving fixed point, total system all cuts off the power supply, and " opening indicator lamp " extinguishes simultaneously.By " electronic pass K1 " key, operation program and above-mentioned identical, but direction of motor rotation is opposite, and the bright time of indicator lamp is the working time (3.3 seconds) that drive motors rotates.The memory temperature sensor is normally open at ordinary times, closes when arriving the memory temperature of setting.Automatically reseting after temperature descends is normally open, can disconnect the wiring of memory temperature sensor at ordinary times to its heating or examination, if during breaking out of fire, whether fire-protection valve 4 moves, and if can move, and illustrates that temperature control system is normal to check.After the memory temperature sensor is through the high temperature action, need treat that it is cooled to when automatically reseting temperature, push " the electronic K2 of opening " key then, its indicator lamp should be shinny immediately, 3.0 extinguish automatically after second, expression fire-protection valve 4 has resetted and has opened, and guarantees that at ordinary times fire-protection valve 4 is in this position.When by " the electronic K2 that opens " key or " electronic pass K1 " key, and corresponding indicator lamp does not work, and illustrates that then the machine work point of YE 5 is in the position that indicator lamp does not work.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, the utility model is easy and simple to handle, the reliability height. When fire takes place, can the autoshutdown fire resisting damper Door, the fire prevention temperature can be set as required, and can monitor the duty of fire-protection valve, can also hold electronic The performance of row device is carried out self check;

2, the utility model diverse in function except having fire-proof function, also has noise elimination, protection against rodents, rainproof Function;

3, at ordinary times all outages of this YE and control system, system-wide operating current is zero, goes out Need not after the factory to adjust automatic protection, once installation, the permanent use.
