Fine spray fire-hydrant

Abstract

The invention relates to a fine water mist fire hydrant capable of effectively solving problems of inconvenient use, high water consumption and poor fire extinguishing effect. The structure is that water inlet pipe assembly components are connected with a support plate panel by positioning clips; a fire reel roll and a reel side plate are connected to form reel assembly components; a support plate is arranged in the roll; a side plate of the reel and the support plate are provided with bearings; each bearing is provided with a cantilever axle; the reel assembly components rotate around the cantilever axle; the outer end of the cantilever axle and a cantilever axle fixing plate are connected; the cantilever axle fixing plate and the support panel are fixed; the support panel is fixed with a fire hydrant box by a pin axis sleeve, a pin axis and a pin axis mounting; the water inlet pipe assembly components are provided with a rotary connector on the inner end of the reel assembly components; one end of the rotary connector is connected with a fire hose winding on the reel assembly components; the water outlet of the fire hose is connected with a high-pressure fine water mist spray gun. The invention has the advantages of novel and unique structure, convenience and flexibility in operation, small size, less installation space, energy saving and environmental protection, and high fire extinguishing efficiency.

Description

1. Technical field [0001] The invention relates to a fire-fighting apparatus, in particular to a fine water mist fire hydrant used in a fine water mist fire extinguishing system. 2. Background technology [0002] At present, the hanging type fire hydrant box and the coil type fire hydrant box are mostly used in China. What the hanging type fire hydrant box is equipped with is a fire hose hanger; It is mostly equipped with a fire hose and an indoor fire hydrant with a diameter of 65mm. It is often used in conjunction with traditional fire water guns and water cannons, which is inconvenient to use and consumes a lot of water (0.8T-2T per minute). During the fire extinguishing process, the water loss is more likely to be greater than the fire loss, which not only wastes water, but also affects the fire extinguishing effect. 3. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide a fine water mist fire hydrant, w...

Problems solved by technology

[0003] In view of the above situation, the object of the present invention is to provide a fine water mist fire hydrant, which can effectively overcome the problems of inconvenient use, large water consumption and poor fire extinguishing effect. The panels are connected together so that the cantilever shaft does not move when the reel assembly rotates. The fire reel drum and the reel side plate are connected to form a reel assembly. The drum is equipped with a support plate, and the reel side plate and the support plate are equipped with bearings. , the bearing is equipped with a cantilever shaft, and the reel assembly rotates around the cantilever shaft. The shaft and pin shaft fixing parts are fixed with the fire hydrant box. The reel assembly rotates within 90 degrees around the pin shaft. The water inlet pipe assembly is equipped with a rotary joint on the inner end of the reel assembly. The fire-fighting hose is connected, and the outlet of the fire-fighting hose is connected with a high-pressure water mist spray gun. The invention has a novel and unique structure, which is flexible, water-saving, light and convenient, easy to operate, flexible, small in size, saves installation space, energy-saving and environmentally friendly, and has high fire-extinguishing efficiency. , using the pin shaft connection method, the fire hose reel can be rotated out of the fire hydrant box as a whole, and the hose can be stretched at any position within 90 degrees. The length of the hose can reach 50 meters, which is suitable for multi-angle fire extinguishing in special spaces, and effectively solves the problem of narrow space Difficult to reach fire extinguishing equipment in dark and other spaces
