Description

  The present invention relates to a splash protection device for a pressurized fire extinguisher that prevents splashing due to a rupture of a container body in the pressurized fire extinguisher.

  By destroying the sealing plate sealing the mouth of the pressurizing gas cylinder placed in the container body, the pressurized gas released from the pressurizing gas cylinder is pumped into the container body and filled into the container body. There is a pressurized fire extinguisher configured to discharge a fire extinguishing agent out of the container body with gas pressure (see, for example, Patent Document 1). As a simple fire extinguisher, it is widely used in buildings, factories, general homes, etc. It is used.

In a pressurized fire extinguisher, an iron container main body is often used from the viewpoint of ease of processing and cost, and in the container main body, the bottom part is connected to the trunk part by welding. .
When the pressure-type fire extinguisher having a container body configured in this way is left in a poor environment such as outdoors for a long time, the welded portion of the bottom of the container body corrodes over the entire circumference, and the container body There are cases where the fire extinguishing agent filled in the inside absorbs moisture and solidifies downward.

When a pressurized fire extinguisher in such a state is activated, there is a risk that the container body will burst due to the gas pressure released in the container body, and the bottom of the container body will come off. When the filled fire extinguishing agent is solidified on the bottom side, the ruptured container body has a propulsive force due to the pressure energy of the pressurized gas released into the container body and the mass of the bottom of the container body and the solidified extinguishing agent. As a result, it may fly on the axis, that is, upward, and may collide with the operator's body and cause harm.
In reality, the old pressurized fire extinguisher is misused, or the old pressurized fire extinguisher is recovered, transported or dismantled for recycling, or the safety plug is lost. A number of cases of personal injury caused by the rupture of the container main body due to the activation of the pressurizing gas cylinder due to the damage of the operation lever portion have been confirmed.
Conventionally, there is no dedicated means for safety in handling of an aged pressurized fire extinguisher with such danger, and it is left to the attention of the handling operator.
