Long distance spray header for fire fighting

Abstract

The invention discloses a long distance spray header for fire fighting, and belongs to the field of fire fighting tools. The long distance spray header comprises a shell body, a quick coupling is connected on the upper shell body, a water separation plate is arranged below the shell body, a glass body is arranged inside the shell body, one end of the glass body is sealed on the water outlet end which is on the upper portion of the shell body, heated expansion liquid is arranged in the glass body, and a switch is arranged on the other end of the glass body; and a worm and gear transmission mechanism is arranged in the shell body, a micro motor is arranged outside the shell body, the micro motor is connected with a worm, the water separation plate is connected with a worm gear, the micro motor drives the water separation plate to move through the worm and gear transmission mechanism, and a transmission box is arranged outside the worm and gear transmission mechanism and fixedly connected to the shell body. According to the long distance spray header for fire fighting, the fire extinguishing area can be increased by using the structure, the service life is prolonged, and the using and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of fire-fighting tools, in particular to a long-distance sprinkler head for fire-fighting. Background technique [0002] At present, the fire sprinkler heads on the market are generally made of plastic or chrome-plated copper, and their service life is up to ten years. The best time to put out a fire. [0003] Secondly, at present, fire sprinklers generally only rely on water pressure to extinguish fires. The fire extinguishing area is generally about 1.5 square meters. A small room needs to install 3-4 sprinklers. The layout and construction of the pipelines are very difficult and expensive. Although the booster pump is currently used to increase the fire extinguishing area, the structural strength of the pipeline and the sprinkler head needs to be increased due to the increase in pressure, and the cost is doubled. [0004] After further investigation, it is found that the replacement and maintenance of the current...

Problems solved by technology

[0002] At present, the fire sprinkler heads on the market are generally made of plastic or chrome-plated copper, and their service life is up to ten years. Best time to put out a fire

[0003] Secondly, at present, fire sprinklers generally only rely on water pressure to extinguish fires. The fire extinguishing area is generally about 1.5 square meters. A small room needs to install 3-4 sprinklers. The layout and construction of the pipelines are very difficult and expensive. Although the booster pump is currently used to increase the fire extinguishing area, the structural strength of the pipeline and the sprinkler head needs to be improved due to the increase in pressure, and the cost is doubled

[0004] After further investigation, it was found that the replacement and maintenance of the current sprinkler heads are also very inconvenient. When maintenance is required, it can only be maintained on the roof, which causes inconvenience to the laborers.
