Description

Fire control emergency spray set Technical Field The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting emergency spraying device. Background The fire-fighting emergency spraying device refers to an automatic water-spraying fire-extinguishing system, is a fixed fire-fighting facility widely applied to buildings, and is mainly used for automatic fire extinguishment in the initial stage of fire. The existing spraying device is usually installed on the ceiling of a building, and the spraying device is connected with a water pipe arranged in a wall body, so that when the building is in a fire disaster, heat can be transferred to a heat-sensitive glass pipe in the spraying device, and when the temperature reaches a set value, the heat-sensitive glass pipe can be broken, and the spraying device can spray, so that the aim of automatically extinguishing the fire is achieved. In view of the fact that the existing spraying device only has one fixed spraying end face, the spraying range is limited, in order to effectively extinguish a serious fire or a fire with a large area, a plurality of spraying devices are usually required to be arranged according to the surface of a ceiling, and large-area water spraying is carried out by the plurality of spraying devices so as to achieve the purpose of effectively extinguishing the fire, but the arrangement mode can definitely lead to the problems of long installation time and complicated arrangement.
