Fire alarm for municipal engineering construction

Abstract

The invention discloses a fire alarm for municipal engineering construction. The fire alarm comprises a central processing unit and an external box body, a water spraying mechanism, a smoke alarm, a camera and a dry powder extinguisher are arranged in the external box body, the smoke alarm is fixedly connected with the external box body, and the smoke alarm is electrically connected with the central processing unit. According to the fire alarm for municipal engineering construction, through cooperation of the central processing unit, the water spraying mechanism, the smoke alarm, the camera, arotating piece, a control mechanism, the dry powder extinguisher and other mechanisms, when a fire occurs, whether a circuit catches fire or not can be judged firstly, then water spraying or dry powder spraying is decided, and the possibility of electric shock is reduced; and moreover, professionals can remotely control the fire extinguisher to spray dry powder, so that the time is saved, the fire can be accurately controlled, and the problems that electric power is possibly leaked when water is directly sprayed in case of a fire, the danger of electric shock of people is increased and the rescue difficulty is increased are solved.

Description

technical field [0001] The invention relates to an alarm device, in particular to a fire alarm for municipal engineering buildings. Background technique [0002] A general smoke alarm is used to prevent the fire from expanding. When the alarm detects smoke, it will control the water pipe to spray water at the same time as the alarm to extinguish the flame. However, the occurrence of the fire is unpredictable, and it may be the circuit A short circuit causes a fire. In this case, if water is sprayed, the power may leak out, increasing the risk of electric shock and increasing the difficulty of rescue. It is possible to reduce the occurrence of this situation. [0003] Moreover, when a fire breaks out, ordinary people may panic. Some people do not know how to use fire extinguishers accurately. Not only can they not control the fire, but they may also run out of dry powder fire extinguishers, delaying the time for fire fighting, and waiting for trained professional security pe...

[0002] A general smoke alarm is used to prevent the fire from expanding. When the alarm detects smoke, it will control the water pipe to spray water at the same time as the alarm to extinguish the flame. However, the occurrence of the fire is unpredictable, and it may be the circuit A short circuit causes a fire. In this case, if water is sprayed, the power may leak out, increasing the risk of electric shock and increasing the difficulty of rescue. may reduce the occurrence of this

[0003] Moreover, when a fire breaks out, ordinary people may panic. Some people do not know how to use fire extinguishers accurately. Not only can they not control the fire, but they may also run out of dry powder fire extinguishers, delaying the time for fire fighting, and waiting for trained professional security personnel. It takes more time to enter the field, which is not conducive to controlling the fire
