Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to an automatic fire-fighting sprinkler device for civil buildings. Background Art

[0002] The automatic fire sprinkler system is a fire extinguishing device and is currently a widely used fixed fire-fighting facility. It has the characteristics of low price and high fire-fighting efficiency. In the prior art, the patent document with the announcement number CN219681541U discloses an automatic fire sprinkler system for civil buildings, including a body, wherein the body is provided with an automatic fire sprinkler structure for civil buildings. The automatic fire sprinkler system for civil buildings includes a housing, wherein the gear is movably connected to the thin rod via a pin, and the thin rod is movably connected to the crossbar via a pin, and the crossbar passes through the limit plate and the housing and is sleeved with the limit plate and the housing. The limit plate is fixedly connected to the inner wall of the housing. Through the cooperation between the automatic fire sprinkler system for civil buildings and the sprinkler head, the smoke alarm will connect to the external power supply of the motor, and the motor will start to drive the straight rod to swing left and right, drive the gear to rotate left and right on the half gear, drive the crossbar to move left and right within the limit plate and the housing, and at the same time drive the water pipe to slide left and right on the slideway processed on the body, drive the sprinkler head to move left and right, and extinguish the fire over a large area reciprocatingly, so that the building fire-fighting equipment can meet the fire extinguishing requirements.

[0003] In civil buildings, where goods are stored, many sprinkler heads are usually installed on the ceiling to cover the entire fire protection area. The large number of sprinkler heads and their exposure to the outside can easily lead to clogging by dust, insects or oil smoke, causing the sprinkler function to fail. If protective covers are installed on each sprinkler head one by one, it will be very troublesome to conduct inspections to see whether they can be opened normally later, which is very inconvenient in actual operation. Based on this, the existing automatic sprinkler device has insufficient protection function and needs further improvement. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic fire sprinkler device for civil buildings to solve the problems raised in the above background technology.
