[0002] The painting in the spray booth section of the painting workshop is done by robots to automatically spray paint on the car body. The spray booth is divided into two layers, with a transparent grille in the middle. The fire hazard level of the section is a serious hazard level and is equipped with a fire protection system. The general fire protection design is to have automatic sprinkler fire extinguishing systems on both the upper and lower layers, with the upper layer being a wet automatic sprinkler fire extinguishing system and the lower layer being an open rain automatic sprinkler fire extinguishing system. Since spraying paint will generate a large amount of paint mist, and the paint mist will continue to adhere to and accumulate on the open drooping sprinkler through the gaps in the grille, the fire protection system cannot ensure that the open drooping sprinkler cannot function normally due to the continuous adhesion and accumulation of paint mist.

[0003] At present, when the paint room in the painting workshop is equipped with an open rain automatic sprinkler fire extinguishing system, the open drooping type sprinkler heads are all set under the grille. Generally, three open drooping type sprinkler heads are set, one on each side and one in the middle. When the painting workshop is in normal production, the open drooping type sprinkler heads of its rain fire extinguishing system will be attached and accumulated by the paint mist in the air.

[0004] In the prior art, there is no effective solution to the technical problem that paint mist is attached and accumulated on the open downward-pointing nozzles in the paint shop, resulting in the nozzles being unable to spray water. Utility Model Content
