Description

Hose reel assembly and multipurpose fire fighting system including it {HOSE-REEL ASSEMBLY AND MULTIPURPOSE FIREFIGHTING SYSTEM}

The present invention relates to a hose reel assembly and a multi-purpose fire fighting system including the same, and more specifically, to a hose reel assembly capable of variously adjusting the extension direction of a hose in response to a fire area and a multi-purpose fire fighting system including the same It is an invention about

In general, roads in downtown attractions, traditional markets, and densely populated residential areas are narrow enough for one small car to pass. Since fire trucks cannot enter these roads, it is difficult to extinguish the fire in the event of a fire. Accordingly, outdoor emergency fire extinguishing devices are being installed in these areas. These outdoor emergency fire extinguishing devices are frequently subject to freezing and bursting in the winter due to outdoor installation, and damage to urban aesthetics and complaints of inconvenience due to their installation have occurred from time to time. In order to solve this problem, Korean Patent No. 10-2007127 "Firefighting battleship system for underground burial" and Korean Patent No. 10-2015231 "Firefighting battleship system for underground burial" suggest a firefighting system buried underground .

The firefighting system has an external shape formed by a housing, and a hose for spraying fire extinguishing water is disposed in the housing. The hose is wound on a reel and stored. Accordingly, the hose is unwound from the reel or wound around the reel as the reel rotates.

According to the structure as described above, since the direction of rotation of the reel is fixed, there are restrictions on the extension direction and movement path of the hose relative to the housing.

The present invention has been proposed to improve the above problems, and to provide a hose reel assembly capable of variously adjusting the extension direction of a hose in response to a fire area and a multi-purpose fire fighting system including the same.

A hose reel assembly according to an embodiment includes a fixing plate including a first through hole; a bracket including a second through hole facing the first through hole and having one surface facing the one surface of the fixing plate; a reel coupled to the other surface of the bracket; a hose wound around the reel; and fixing bolts coupled to the first through hole and the second through hole, and the bracket rotates clockwise or counterclockwise around the fixing bolt.

According to the present embodiment, since the extension direction of the hose can be set in various ways through the rotation of the bracket according to the area where the fire occurs, the user's convenience of use is improved and the fire can be extinguished quickly.
