Description

The present invention relates to a disaster prevention device used in a disaster prevention facility that monitors abnormalities such as fire, theft, and gas leakage.

  Conventionally, in the construction of disaster prevention equipment such as fire alarm equipment and automatic fire extinguishing equipment, for example, for sprinkler heads, external impact is caused by hitting important thermal parts of the head with other equipment construction work before construction completion. There is a risk of adding. Therefore, a protective cap is attached to the sprinkler head immediately before the completion of construction to protect the head. In addition, there is a case where the color of the protective cap is made fluorescent to make the head position conspicuous (Patent Document 1).

In addition, in the case of photoelectric smoke detectors, dust and dust when installed on the construction site enter through the smoke detector's smoke inlet, clog the insect screen, or enter the smoke detector. In order to prevent the detection function from being deteriorated by changing the detection sensitivity, a dustproof cover is attached (Patent Document 2).

  However, in the case of a protective cap attached to such a conventional sprinkler head, when the construction site becomes dark, even if it is a fluorescent color, its presence becomes inconspicuous, and hitting with a helmet etc. hits more than expected When added to the head, there is a problem that the head is damaged although it is protected by the cap.

  After the ceiling is finished, the protective cap will be removed. However, since the position of the head is inconspicuous at the site, there is a possibility that the protective cap may be forgotten only by visual confirmation. For this reason, it is necessary to remove the protective cap while confirming the installation position of the head on the construction drawing, and there is a problem that it takes time and effort.

  On the other hand, smoke detectors with dust covers are removed after construction is complete, but if you do not do this, monitoring will become impossible, so you will also need to check the construction drawings, which takes time and effort. .

  In the field installation of the fire detector, the detector base is fixedly installed on the ceiling surface, and then the detector main body is mounted on the detector base. However, even when the sensor main body is installed on the sensor base before the construction is completed, the installation position of the sensor base is difficult to understand at the site, and it is necessary to confirm it with construction drawings, which takes time and effort.

  Such a problem also arises with respect to appropriate members attached to the disaster prevention equipment only during construction. In addition, if a test operation is performed by manual operation at the site during inspections during operation of the equipment, it must be restored after the inspection is completed. There is.

An object of this invention is to provide the disaster prevention apparatus which can confirm easily the state which is different from the normal of the apparatus which requires removal operation | movement, a return operation, etc. at the time of construction or inspection even if the surroundings are dark.

  In order to achieve this object, the present invention is configured as follows. In the disaster prevention device, the present invention is that a part or member that cannot be visually recognized from the outside in a normal device state and is visually recognized from the outside in a device state different from a normal state is formed of a phosphorescent material containing a phosphorescent substance. Features.

  Specifically, the site | part or member visually recognized from the exterior at the time of a maintenance or construction is formed with the luminous material containing the luminous substance.

  In the case of a sprinkler head, part or all of a removable protective cap that is attached to the sprinkler head at the time of construction is formed of the phosphorescent material.

  In the case of a smoke sensor, a part or all of the sensor base fixed to the ceiling surface exposed when the sensor body is removed is formed of a phosphorescent material.

  In the case of a fire extinguisher, part or all of the mounting portion of the pedestal on which the fire extinguisher is placed is formed of a phosphorescent material. Further, in the case of a fire extinguisher storage box for storing a fire extinguisher, the back surface of the fire extinguisher door in which the fire extinguisher is freely opened and closed or a part of the inside of the fire extinguisher door is formed of a phosphorescent material.

In the case of a manual operation box of a disaster prevention facility, a part or all of the back surface or inside of an openable / closable lid provided in the manual operation box is formed of a phosphorescent material. The phosphorescent material is a synthetic resin containing a phosphorescent substance.

  According to the present invention, the part formed of the phosphorescent material of the disaster prevention device is stimulated by light such as sunlight, fluorescent lamp, incandescent lamp during construction, so it will emit light in the dark, It is a part visually recognized from the outside in a device state different from normal, and its location can be confirmed immediately. In particular, since the entire component that has received light emits light, there is no blind spot, and the location can be confirmed with certainty.

  In addition, the present invention is less expensive than painting a part after it is completed or attaching a seal or the like by molding a part that is a resin material as it is with a resin material containing a phosphorescent substance instead of fluorescent coating.

  Also, when the ceiling surface is high, even if it is a fluorescent color, the color may not enter the field of view, but according to the phosphorescent material of the present invention, it is easy to visually recognize by emitting light in a dark place. And the installation state can be reliably identified.

  If the protective cap of the sprinkler head is made of a phosphorescent material, the installation location can be easily identified even in the dark, so that it is possible to be alerted during construction and the head can be reliably protected.

  When the dust-proof cover to be attached to the smoke detector is formed of a phosphorescent member, the presence or absence of the removal can be surely recognized when the surroundings are dark. In addition, when construction of another facility is unavoidable, a dust cover is unavoidably installed to prevent malfunctions, the protective compartment is unwarned by the light emission of the dust cover, so it remains attached. Is visible.

  If the sensor base of the fire sensor is made of phosphorescent material, the sensor body part does not emit light, and only the unconnected sensor base part emits light. You can easily see how.

  In the case of a fire extinguisher, since the phosphorescent material on the pedestal appears to emit light, it can be visually confirmed that the fire extinguisher is not placed, and appropriate measures can be taken.

In the case of a manual operation box of a disaster prevention facility, the back of the lid appears to emit light, so that a user can visually recognize forgetting to return due to an inspection operation or the like, and can perform a recovery operation.

  FIG. 1 shows an embodiment of a disaster prevention device according to the present invention. In this embodiment, a protective cap to be attached to a sprinkler head is formed of a phosphorescent material.

  In FIG. 1, the sprinkler head 10 is fixed by screwing to the tip of a water supply pipe 11 that is lowered from the ceiling, and a heat-sensitive operation unit 14 is disposed at a lower portion of a frame 12 that becomes a head body. A valve member that closes the inlet of the water supply pipe 11 is disposed in the frame 12, and this valve member is held in a closed state in an assembled state using low-temperature solder or the like by the lower heat-sensitive operation unit 14.

  For such a sprinkler head 10, when the sprinkler fire extinguishing equipment is installed, an object hits the thermal operation section 14 and is damaged, or a coating agent is sprayed on the thermal operation section 14 and the frame 12 when painting the ceiling surface. In order to prevent the attachment of the protective cap 16, a protective cap 16 is attached.

  The protective cap 16 has a cap shape with the bottom closed and opened upward, and fitting claws 18 projecting at a plurality of locations inside the upper opening. On the other hand, a fitting groove 15 is formed on the outer periphery of the frame 12 of the sprinkler head 10.

  When the protective cap 16 is attached to the sprinkler head 10, the protective cap 16 is fitted from the lower side toward the heat-sensitive operating portion 14 of the sprinkler head 10 as indicated by an arrow, and when it is pushed upward, the fitting that protrudes inside the protective cap 16. The claw 18 is fitted into the fitting groove 15 formed on the outer periphery of the frame 12, and the protective cap 16 can be fixed to the sprinkler head 10.

  In the present invention, the protective cap 16 attached to the sprinkler head 10 includes a phosphorescent substance in the synthetic resin used for injection molding of the protective cap 16. The phosphorescent material to be included in the synthetic resin constituting the protective cap 16 is, for example, a material in which an oxide such as strontium carbonate and rare earth elements are combined with aluminum oxide having stable chemical properties as a base material. It is 20 microns or less, accumulates light by sunlight, illumination light, etc., and has a afterglow phenomenon in which the phosphorescent material emits light in a sufficient time after the light is cut off.

  By attaching the protective cap 16 containing such a phosphorescent substance to the sprinkler head 10, when the construction work of the sprinkler head 10 is completed, all unnecessary protective caps 16 are removed. In this case, even if the protective cap 16 is forgotten to be removed, for example, when the light is turned off while the room light is on, the protective cap 16 remains on the sprinkler head 10 installed on the ceiling surface. In such a case, the installation state of the protective cap 16 that has been forgotten to be removed due to the light emission of the phosphorescent member contained in the protective cap 16 can be clearly seen, thereby reliably preventing forgetting to remove the protective cap 16. it can.

  FIG. 2 shows another embodiment of the disaster prevention device according to the present invention. In this embodiment, the sensor base for attaching the fire sensor to the ceiling surface is formed of a phosphorescent material.

  In FIG. 2, at the time of construction, the detector base 24 in the smoke detector 20 is attached to the attachment hole 32 formed in the ceiling surface 30 by using the attachment bracket 34 arranged on the back side of the ceiling. That is, the smoke detector 20 is composed of a sensor body 22 and a sensor base 24, and the sensor base 24 is screwed into a screw hole 38 of a mounting bracket 34 arranged on the back side of the ceiling surface 30. The mounting hole 32 is fixedly attached.

  On the other hand, the sensor body 22 is provided with a cover 26 on the lower tip side, and a plurality of smoke inlets 28 are opened around the cover 26. Inside the cover 26 is provided a smoke detection chamber arranged with a predetermined angle so that the light emitting element and the light receiving element do not face each other, and light from the light emitting part due to smoke flowing into the smoke detection chamber from the smoke inlet 28. The scattered light is received by a light receiving unit and converted into an electric signal, and when the received light signal exceeds a predetermined threshold, it is determined that a fire has occurred and a fire alarm signal is output.

  In such a smoke sensor 20, in the present invention, as the sensor base 24 attached to the ceiling surface 30, the sensor base 24 is made to contain a phosphorescent material in an injection-molded synthetic resin, whereby the sensor base 24. The light emitting surface 40 is used as the lower part.

  With the configuration in which the portion of the sensor base 24 to which the sensor body 22 is mounted is the light emitting surface 40, the sensor provided on the upper back surface of the sensor body 22 after the installation work of the sensor base 24 is completed. The sensor main body 22 is mounted by turning around the sensor base 24 using fitting fittings that are electrically and mechanically engaged with the sensor base 24.

  As a confirmation work after mounting the sensor main body 22 to the sensor base 24 in this way, if the installation work of the sensor main body 22 is completed with the room illumination turned on, the room illumination is turned off. Check if there is a light emitting part on the ceiling. If the sensor main body 22 is not attached to the sensor base 24, the light emitting surface 40 is exposed to the outside, so that when the illumination is turned off, light from the phosphorescent member contained in the light emitting surface 40 is received. As a result, the sensor base 24 to which the sensor body 22 is not attached can be clearly seen.

  FIG. 3 shows another embodiment of the disaster prevention device according to the present invention. This embodiment is characterized in that a dustproof cover to be attached to the sensor body is formed of a phosphorescent material.

  In FIG. 3, the smoke sensor 20 includes a sensor body 22 and a sensor base 24, and the attachment of the sensor base 24 to the ceiling surface 30 is the same as in the embodiment of FIG. 2. In such a smoke detector 20, a dustproof cover 42 having a function as a cushioning material when the detector main body 22 is boxed is mounted when the box is shipped in a factory.

  When the detector main body 22 is attached to the sensor base 24 fixed to the ceiling surface 30 at the construction site of the fire alarm facility, dust and dust accompanying the construction work enter the dustproof cover 42 from the smoke inlet 28. In order to prevent clogging of the insect screen formed around the smoke detector, or to enter the smoke detector space inside the insect screen and change the detection sensitivity of the scattered light smoke detection mechanism, the sensor It is mounted so as to cover the cover 26 of the main body 22.

  That is, the dust-proof cover 42 has a concave portion 44 that accommodates the portion of the cover 26 that protrudes from the lower portion of the sensor body 22, and functions as a buffer material around the concave portion 44 in the form of a ring in this embodiment. The engaging projections 46 are formed at a plurality of locations on the inner periphery of the concave portion 44, and the engaging projections 46 are assembled to the sensor body 22, so that the smoke inlet 28 is provided around the cover 26. It can be fitted to prevent it from coming off.

  In the present invention, when the dust-proof cover 42 is formed of, for example, a synthetic resin, a dust-storing material is contained in the synthetic resin. For this reason, the dustproof cover 42 is always attached to the lower part of the smoke detector 20 during construction, and the dustproof cover 42 is made of a synthetic resin material containing a phosphorescent substance. Light energy is accumulated in the phosphorescent material upon exposure to light or illumination, and thereafter, when it becomes darker at night or the like, the light energy is gradually released from the phosphorescent material to enter a light emitting state.

  When the construction work has progressed to some extent or has been completed, the dust cover 42 attached to the smoke detector 20 is removed, the smoke inlet 28 is opened, and a fire monitoring state is established by the smoke detector 20. .

  At this time, since the smoke detector 20 is installed in a dark place on the ceiling surface 30 side, it is difficult to confirm whether or not the dust-proof cover 42 has been removed. However, in the present invention, since the dustproof cover 42 contains a phosphorescent substance, for example, when the room lighting is turned off, if the dustproof cover 42 is attached to the smoke detector 20, the dustproof cover 42. The attached state of the dustproof cover 42 can be immediately recognized by light emission from the phosphorescent substance.

  For this reason, when the smoke detector 20 is in a monitoring state, if the user forgets to remove the dust-proof cover 42, the presence of the dust-proof cover 42 is immediately known from the light emission by the phosphorescent material, and it is ensured that the dust-proof cover 42 is forgotten to be removed. Can be prevented.

  In addition, during the construction, once the smoke detector 20 is in a monitoring state, in order to prevent the smoke detector 20 from being operated depending on the location, the dust cover 42 should be reattached or left without being removed. There is a case. Even in such a case, when the room becomes dark, it can be easily recognized that the phosphorescent material of the dust-proof cover 42 emits light and the dust-proof cover 42 is attached. You can easily confirm that the place is in a non-warning state.

  FIG. 4 shows another embodiment of the disaster prevention device according to the present invention. In this embodiment, the open state of the door of the fire extinguisher storage box is notified by light emission by a phosphorescent material.

In the present invention, such a fire extinguisher storage box 50 is provided with a phosphorescent member 64 on the back surface of the door 52.

  Since the door 52 is closed in the normal state of FIG. 4A, the phosphorescent member 64 is located inside, and the light emission of the phosphorescent member 64 cannot be seen from the outside. On the other hand, when the door 52 of the fire extinguisher storage box 50 is opened as shown in FIG. 4B, the phosphorescent member 64 is exposed to the outside, and light energy is accumulated by receiving sunlight or illumination light. The

  In this state, at night or the like, the phosphorescent material of the phosphorescent member 64 emits light energy, and the phosphorescent member 64 as a whole emits light. Due to the light emission of the phosphorescent member 64 of the door 52, the door 52 of the fire extinguisher storage box 50 has some reason. Thus, it can be easily seen from the outside that it remains open, and the door 56 can be closed to return to the normal state. The phosphorescent member 64 may be provided in the storage chamber 62 in addition to the back surface of the door.
