Description

  The present invention relates to a fire extinguishing apparatus that automatically shifts to a fire extinguishing operation upon detecting an unexpected fire, and more specifically, configured to be able to disperse a fire extinguishing material widely and uniformly. It relates to fire extinguishing equipment.

  In the fire extinguishing apparatus, for example, there is a configuration disclosed in Patent Document 1, and this fire extinguishing apparatus is installed with a container body containing a fire extinguishing material at a garbage input such as a garbage can, and when the garbage is ignited, The container body is destroyed by the heat of the flame due to ignition, and the fire extinguishing material stored in the container body is released.

  In the conventional fire extinguishing apparatus, a container body containing a fire extinguishing material is formed from an elastic and combustible film member such as a cellophane, a plastic film, an emulsion or a latex film, and the fire extinguishing material and air are stored in the container body. ing.

  Then, when the container containing the fire extinguishing material and air is installed at the garbage inlet such as a trash can, when the trash in the trash can ignites, the container is melted by the heat of the flame by the flame of the ignition, The fire extinguishing material accommodated in the container body is released from the open hole to the outside of the container body, and the flame is extinguished.

  However, in the state where the fire extinguishing material is released out of the container body, the fire extinguishing material in the container body is released vigorously at the moment when the container body of the fire extinguishing device is melted by the flame and scattered around the moment. The fire extinguishing material is discharged downward from the melted hole of the body.

  Therefore, the flame immediately below the melted hole in the container is extinguished by the fire extinguishing material, but the flame far from the hole must be extinguished by the fire extinguishing material scattered at the moment the container melts. After that, it may continue to burn.

  For this reason, when installing a fire extinguisher in a large trash box, many fire extinguishing apparatuses had to be installed, which was not economical.

  In addition, since most of the fire extinguishing material stored in the container flows down directly under the melted hole of the bag, especially when a liquid is used for the fire extinguishing material, after the fire extinguishing liquid is discharged, the member installed with the fire extinguishing device If the container is a non-sealed container, the fire extinguishing material may leak from the container.

JP 2004-305229 A (pages 1-7, FIGS. 1-7)

  The present invention provides a fire extinguishing material in which the fire extinguishing material stored in the container is uniformly scattered around the fire extinguishing device, and the fire extinguishing material is sufficiently distributed to the ignition point away from the fire extinguishing device to surely extinguish the fire. The object is to provide a device.

  In order to solve the above-described problems, a fire extinguishing apparatus according to the present invention is a fire extinguishing apparatus configured by a container body that contains a fire extinguishing material, and a thermal body that senses heat and destroys the container body. The body is made of an elastic material formed into a tube shape by extrusion molding.

  Further, the container body is arranged in a substantially circular shape, the inside of the container body is held at a positive pressure, or a gas is stored together with a fire extinguishing material inside the container body.

The container body is covered with a shape-retaining member formed of a material that is difficult to expand and contract. Further, the shape retaining member is configured in a mesh shape.
Further, the elastic material is made of a silicone resin material.

  Furthermore, the thermal body is composed of a stopper made of a melting member that melts at 60 ° C. to 90 ° C. and a breaking member that is locked to the stopper and moves so as to break the container body when the lock is released. is there.

  The melting member is made of a solder material or a needle-shaped material.

  According to the fire extinguishing apparatus of the present invention, when the fire extinguishing apparatus is installed in the upper part of the trash bin, for example, if the trash in the trash bin ignites or burns for some reason, the heat generated by the ignition or roaring is When the temperature of the stopper (melting member) reaches 60 ° C. to 90 ° C. due to heat from ignition or roaring, the heat is applied to the stopper (melting). The member is melted, the locking of the breaking member is released, and the breaking member to which the elastic force is applied in advance moves in the direction of the container body formed from the silicone resin material by the elastic restoring force and collides. By this collision, the surface of the container formed from the silicone resin material is torn, and the fire extinguishing material stored inside the container is instantaneously released to the outside.

  The release of the fire extinguishing material in the container body is released so that the fire extinguishing material is instantaneously pushed out of the high internal pressure container body into the normal pressure trash can from the tear generated in the container body. The fire extinguishing material can be scattered over a wide area in the trash can, and the wide area in the trash can can be extinguished uniformly.

  In addition, since the fire extinguishing material filled in the trash box due to scattering falls on the burning garbage sequentially, the fire extinguishing action is continued until the last fire extinguishing material falls.

  Since the container body for containing the fire extinguishing material is formed into a tube shape by extruding the silicone resin material, the stress applied to the tube during the extrusion molding of the silicone resin material becomes the longitudinal direction of the tube. When the stress applied to this tubular container body formed by molding is in the longitudinal direction of the container body, that is, the extrusion direction of the silicone-based resin material, when a hole is opened on the surface of the container body by the breaking member described above, The hole tries to spread in the direction of the stress applied during molding of the container body, and the hole is the starting point, and the slit is linearly cut toward the both ends of the tube-shaped container body made of silicone resin material. And the crevices enter both ends of the tube-like container in an instant.

  As a result, the fire extinguishing material stored in the container body is released to the outside of the container body from the rift generated in the container body in an instant and with a width substantially equal to the width in the longitudinal direction of the tube-shaped container body. When the fire extinguishing material is released, the fire extinguishing material can be scattered uniformly and widely.

  In addition, by covering the container body containing the fire extinguishing material with a shape-retaining member formed of a material that is difficult to expand and contract, when the fire extinguishing material is injected into the container body, the injected fire extinguishing material is collected in one place of the container body. Thus, the fire extinguishing material can be smoothly poured into the container body without causing the container body to partially swell.

  And even when storing the container body into which the fire extinguishing material has been injected or when transporting the container body, the shape retaining member prevents direct contact between the surface of the container body and a member such as a packing material. This container body can be prevented from bursting during transportation.

  Furthermore, by forming the shape retaining member in a mesh shape, the container body into which the fire extinguishing material is injected can be set as it is in the fire extinguishing apparatus.

  In other words, when ignition or smoldering occurs in a trash box with a fire extinguisher attached, even if the destruction member of the thermal moving body moves to destroy the container body that stores the fire extinguishing material, the container body is covered. Since the shape member has a mesh shape, the breaking portion of the breaking member can pass through the mesh eyes and collide with the surface of the container body.

  In addition, the fire extinguishing material can be prevented from drooping downward from the container body by setting the container body on the fire extinguishing apparatus while being covered with a shape-retaining member formed of a material that does not easily expand and contract, so that the fire extinguishing material is not unevenly distributed. The fire extinguishing material can be discharged more uniformly when the fire extinguishing material is released.

  From the above, the fire extinguishing apparatus of the present invention has a container body that contains the fire extinguishing material formed into a tube shape by extrusion molding of a silicone resin material. Most of the fire extinguishing materials do not flow directly under the opening of the discharge part, and the fire extinguishing material can be scattered over a wide area of the trash can, so even when installing a fire extinguishing device in a large trash can It is also possible to reduce the number of fire extinguishing devices installed.

  In addition, when the fire extinguishing device is operated by installing this tubular container body in a circular shape, a tear enters in the front-rear direction with respect to the longitudinal direction of the tubular container body. Since it spreads in a circular shape and scatters, the fire extinguishing material can be spread evenly.

  Furthermore, even in a fire extinguishing liquid in which the fire extinguishing material is composed of a liquid, the container body that contains the fire extinguishing liquid is instantaneously, and the fire extinguishing liquid has a high internal pressure in the tube-shaped container body with approximately the same width as the longitudinal direction Since the fire extinguisher is released in a granular manner and the fire extinguishing liquid is uniformly scattered over a wide area of the recycle bin, the fire extinguisher is released in the recycle bin. Even if the member on which the fire extinguishing device is installed is an unsealed container attached to or absorbed in the garbage, there is no risk of extinguishing the fire extinguishing liquid from the container, and there is no possibility of soiling the floor on which the container is installed.

Hereinafter, the fire extinguisher of this invention is demonstrated based on an accompanying drawing.
