Description

A fire hose automatic drainage and zoned winding structure Technical field

The invention belongs to auxiliary equipment for fire protection, and specifically relates to a fire hose automatic drainage and zoned winding structure.

Background technique

Fire hoses are hoses used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses are lined with rubber and the outer surface is wrapped with flax braid. Advanced fire hoses are made of polymer materials such as polyurethane. , there are metal connectors at both ends of the fire hose, which can be connected to another hose to extend the distance or to connect a nozzle.

After the fire extinguishing is completed, the fire hose needs to be rolled up. The traditional way to store fire hoses is for on-site firefighters to roll them up manually. Since the fire hose is wet and long, and the firefighters have just started firefighting work, the rewinding of the fire hose is easy to consume the firefighters' physical strength, and it is difficult to squeeze out the remaining water in the fire hose. The weight of the fire hose increases, which increases the burden on subsequent transportation of the fire hose, affects the handling efficiency, and delays firefighting time. It can be seen that when firefighters roll up and store wet and long fire hoses, the fire hoses tend to retain more moisture, resulting in insufficient winding tightness and heavy defects.

Chinese invention patent CN111632325 discloses a fire hose rewinding device, which includes a base plate. A first upright column and a second upright column are fixed on the base plate. A rotating circular tube is connected to a bearing on the second upright column. The end of the rotating circular tube is fixed with a The first baffle is provided with a central tube, the side wall of the central tube is provided with a strip opening, and the bottom plate is provided with a driving assembly; the first column is provided with a first support shaft and a second support shaft. The first support shaft and the second support shaft are respectively provided with a first rotating sleeve and a second rotating sleeve. The second supporting shaft is fixed on the side of the first upright column, and a pressing assembly is also provided on the first upright column. The fire hose rewinding device passes the water hose between the first rotating sleeve and the second rotating sleeve and extends into the strip opening, so that the hose head is embedded in the central cylinder, and the central cylinder is driven by the motor to rotate, that is, The water hose can be rolled up, and the first rotating sleeve and the second rotating sleeve are used to squeeze the water hose to squeeze out the remaining water in the hose. However, it cannot pass the fire hose joints connected to the fire hose, and only winds up one section of the fire hose. It cannot be operated to wind up the fire hoses connected by multiple fire hose joints, and it is necessary to Manual operation, collecting one piece at a time, cannot truly liberate manpower.

In addition, when rewinding, there is only a small amount of water left in the fire hose, which is flat, the fire hose interface is made of metal, and the fire hose interface protrudes. When the fire hose and fire hose interface are rolled up on the same roll, , it is very easy for some fire hose joints to be wound on the fire hose, but when the fire hose next to it is rolled up, it slips away from the fire hose joint and is rolled onto another roll, resulting in a fire hose and a fire hose. Some structures are wound tightly, while others slip and loosen. The connection between the fire hose and the fire hose has a high-to-low connection slope, causing the fire hose to be rolled unevenly and randomly, which is prone to fire hazards. If the hose is stuck and cannot rotate, or is piled up in a mess, it will affect the rewinding capacity of the fire hose and affect the subsequent pulling out of the fire hose for use.

Therefore, how to completely solve the problems that fire hoses and fire hose joints cannot be continuously rolled up, fire hoses are not completely drained, and fire hoses cannot pass when folded, and simultaneously realize the continuous rolling up of fire hoses and fire hose joints, and fire protection Water hoses can also be used for drainage and fire hose folding. When automatically winding fire hoses, winding fire hoses and interfaces are divided into zones to increase the winding amount and make the winding even and regular. This is an urgent need for those skilled in the field. Technical issues resolved.
