Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing, in particular to a fire extinguishing sprinkler device. Background Technique

[0002] "Fire protection" means eliminating potential hazards and preventing disasters. Of course, in the initial stage of people's understanding, the meaning of fire protection was: (extinguishing) fires. It mainly includes the rescue of personnel at the fire scene, the rescue of important facilities, equipment and cultural relics, the security and rescue of important property, and extinguishing fires. The purpose is to reduce the degree of damage caused by fires and minimize casualties and property losses. Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the splash plate of the sprinkler head for fire extinguishing, which is divided into pendant sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, sidewall sprinkler heads, etc.

[0003] At present, Chinese Patent No. CN202123276819.5 discloses a fire extinguishing sprinkler device, which connects a water tank, a booster pump and a sprinkler head through pipes. The water in the water tank is sprayed out from the sprinkler head under the action of the booster pump for fire fighting operations. The movement of the sprinkler head is controlled by a control mechanism, so there is no need to hold the sprinkler head and pipes for fire fighting operations, which reduces the labor intensity of fire fighting operations and improves the safety of fire fighting operations.

[0004] In the existing fire protection projects, when extinguishing fires, it is necessary to use a water pipe to spray water at the fire location.
