Description

Fire alarm system

Technical Field

The utility model relates to a fire control field specifically is a fire alarm system.

Background

The automatic fire alarm system consists of trigger, fire alarm, linkage output unit and other auxiliary functional units, and it can convert the physical quantities of smoke, heat and flame produced by burning into electric signal through fire detector and transmit the electric signal to fire alarm controller in the initial stage of fire and inform the evacuation of the whole floor in the form of sound or light.

Fire alarm device is a commonly used alarm device in the tall building mansion at present, office area in the tall building mansion at present often can the furred ceiling, the lower extreme at the furred ceiling is often installed to the alarm, and furred ceiling top space often has a lot of circuit electric wires, this just leads to when circuit electric wire appearance ageing short circuit takes place the condition of a fire, the alarm is owing to install the lower extreme at the furred ceiling, the condition of a fire of furred ceiling upper end can't in time be sensed, this can delay best conflagration rescue time, cause the casualties.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Not enough to prior art, the utility model provides a fire alarm system to solve the problem that the background art provided.

(II) technical scheme

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a fire alarm system, is including installing the alarm at the furred ceiling lower extreme, be fixed with the shell on the lateral wall of alarm, set up the guide way that runs through in the shell, the upper end of furred ceiling is fixed with the inner shell, the flue inlet that matches with the guide way is seted up to the lateral wall of inner shell.

Preferably, the upper end of the alarm is fixed with a baffle plate, and the number of the baffle plates corresponds to the position of the smoke inlet.

Preferably, the number of the guide grooves corresponds to the position of the blocking piece.

Preferably, the inner shell is arranged in a large-end-up mode, and the opening at the lower end of the inner shell is matched with the diameter of the alarm.

Preferably, a filter screen is fixed on an upper end opening of the inner shell.

(III) advantageous effects

Compared with the prior art, the utility model discloses possess following beneficial effect:

1. this kind of novel be applied to fire alarm system through setting up shell and inner shell, has seted up the guide way in the shell, has seted up into the mouth on the inner shell, and smog gets into through advancing the mouth, leads to the response department of alarm through the guide way and makes the alarm report to the police.

2. This kind of novel fire alarm system that is applied to, through setting up the separation blade, the separation blade can block horizontal route with the smog that gets into the mouth of a cigarette, makes during the easier entering guide way of smog, has increased the sensitivity of reporting to the police.

Fig. 1 is a schematic view of the overall bottom structure of the present invention;

fig. 2 is a schematic view of an overall top view structure of the present invention;

fig. 3 is a schematic view of an overall cross-sectional structure of the present invention.

In the figure: 1. an alarm; 2. a suspended ceiling; 3. a housing; 4. an inner shell; 5. a guide groove; 6. a smoke inlet; 7. a baffle plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, a fire alarm system comprises an alarm 1 mounted at the lower end of a ceiling 2, an outer shell 3 is fixed on the outer side wall of the alarm 1, a through guide groove 5 is formed in the outer shell 3, an inner shell 4 is fixed at the upper end of the ceiling 2, and a smoke inlet 6 matched with the guide groove 5 is formed in the side wall of the inner shell 4.

As shown in fig. 3, a blocking piece 7 is fixed at the upper end of the alarm 1, the number of the blocking pieces 7 corresponds to the position of the smoke inlet 6, smoke passes through the smoke inlet 6 and meets the blocking piece 7, then enters the guide groove 5 through the blocking piece 7, and the sensor which is guided to the alarm 1 through the guide groove 5 triggers the alarm 1 to alarm.

As shown in fig. 3, the number of the guide grooves 5 corresponds to the position of the stopper 7, and the guide grooves 5 and the stoppers 7 are provided in all four directions.

As shown in fig. 2 and 3, the inner shell 4 is arranged in a large-top and small-bottom manner, and the opening at the lower end is matched with the diameter of the alarm 1, so that the smoke can enter the inner shell 4 conveniently even if the upper opening is large.

As shown in fig. 3, a filter screen is fixed on the upper opening of the inner shell 4, and the filter screen can prevent foreign matters from falling into the alarm 1 to block smoke.

The working principle is as follows: during the use, when the condition of a fire takes place in the upper end of furred ceiling 2, the smog that the condition of a fire produced can be through the upper end opening part of inner shell 4 and advance 6 departments of cigarette mouth and get into, meet separation blade 7 when smog gets into from advancing 6 cigarette mouths, smog can trigger the alarm through 5 response departments of transmitting to alarm 1 of guide way after that, win the time for the condition of a fire rescue.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
