In addition, the smoke at the ignition point can be quickly sucked, the smoke alarm can quickly detect and judge, the reaction speed is improved, and the loss is reduced. If the discovery condition of a fire, this scheme structure is changed into extinguishing device at once, puts out a fire through the fire control water pump, and reaction rate is fast, the good reliability.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
The sequence numbers in the figures illustrate: the device comprises a main pipe 1, a branch pipe 2, an opening 3, a fan 4, a smoke alarm 5, a valve 6, a fire-fighting water pipe 7, a nozzle 8, a bracket 9 and a pipe gallery 10.
Detailed Description
As shown in fig. 1, the utility model discloses an automatic alarm device applied to underground comprehensive pipe gallery, including a branch pipe 2 arranged above the inside of a pipe gallery 10, a main pipe 1 located in the middle and connected with two adjacent branch pipes simultaneously, the main pipe passing through the opening of the pipe gallery and located outside the pipe gallery, one end of the branch pipe is closed, and the other end is welded and fixed with the main pipe; a plurality of openings 3 are arranged on the branch pipe, and the openings 3 can be used for ventilating and draining water; the fan 4 for air extraction is arranged at one end of the main pipe, which is positioned outside, and the fan can be used for air exchange (exhaust) inside the pipe gallery under a normal state so as to prevent the temperature or humidity of the air in the inner space from being too high, and the content of oxygen and the like from being reduced, which causes danger to maintenance personnel; a smoke alarm 5 is arranged above the joint of the two branch pipes in the main pipe, is a high-sensitivity alarm, can detect the smoke content in the air, thereby judging whether the fire risk exists or not, has an alarm function, and can realize the functions of audible and visual alarm, remote alarm, linkage device starting and the like; be provided with valve 6 in the downside of fan, the valve is in the open mode when bleeding, has fire hose 7 in the downside intercommunication of valve, is used for to being responsible for in emergency and annotates water, and the valve seals when the water injection in order to prevent leaking. The valve can be a quick exhaust valve, an electromagnetic valve, a passive quick automatic cut-off valve and the like.
Preferably: the joint parts of the two branch pipes are symmetrically arranged relative to the main pipe, are communicated with the main pipe in a manner of being tangent to the outer wall of the main pipe and are welded and connected. The arrangement mode can ensure that the gas in the two branch pipes is uniformly mixed, thereby being convenient for the detection of the alarm.
Preferably: the alarm is fixed inside the main pipe through a support 9 welded on the main pipe.
Preferably: the fire-fighting water pipe is communicated with a fire-fighting water pool through a fire-fighting water pump.
Preferably: the branch pipe is welded or bolted with a fixed frame screwed on the wall of the pipe gallery.
Preferably: a spray head 8 is arranged on the opening. The spray head can also pass through certain gas, and is convenient for spraying water outwards.
The working process of the utility model is as follows: under normal conditions, the fan is started for exhausting the gas in the pipe gallery to achieve the effect of ventilation. In the exhaust process, the inside air of piping lane enters into the branch pipe from the trompil of branch pipe to with the tangential direction entering and being responsible for, be responsible for inside through becoming backward, the misce bene, and upward move and be responsible for the upper end opening through the fan discharge. In the process, the smoke alarm with the detection and alarm function detects the mixed gas, and judges whether fire and hidden danger exist according to the detected numerical value and preset parameters. If the result is normal, no reaction is carried out; if a certain hidden danger exists (the risk is small), an alarm can be given; if a fire alarm is judged, signals are output to the valve and the fire pump while the alarm is given, the valve is closed, the water pump is started, water is led into the main pipe and is sprayed out through the main pipe, the branch pipe and the opening to reach a fire point for fire extinguishing. In order to achieve better effect, the water can be sprayed in a large and uniform area by arranging the direction and increasing the spray pipes or spray heads, so that better effect is achieved.
In this scheme, the branch pipe sets up along piping lane length direction usually, when increasing the degree of depth of taking a breath and reducing fan quantity, can also prolong the induction distance to flue gas in the space, is equivalent to the monitoring range who makes single smoke alarm increases. In addition, the smoke at the ignition point can be quickly sucked, the smoke alarm can quickly detect and judge, the reaction speed is improved, and the loss is reduced. If the discovery condition of a fire, this scheme structure is changed into extinguishing device at once, puts out a fire through the fire control water pump, and reaction rate is fast, the good reliability. Only the smoke alarm needs to be checked or replaced afterwards.
