Description

  The present invention relates to a package-type fire extinguishing apparatus, and more particularly, to housing the fire hose.

  A package-type fire extinguisher is a compact package-type fire extinguisher that is easy to use in the image of a fire extinguisher and that has a fire extinguishing capacity similar to that of a fire hydrant. It will be installed in a place where construction work such as piping is not possible. The package-type fire extinguisher houses a fire extinguisher-filled container and a fire hose with a fire extinguishing nozzle connected at the tip in a housing with an open / close door on the front. Are suspended from hose racks erected from the both sides of the casing in the front direction of the casing and then wound around the inner wall surface of the casing (see, for example, Patent Documents 1 and 2).

  In such a conventional package-type fire extinguisher, when a fire occurs, it is necessary to pull out the fire hose from the inside of the housing to perform the fire extinguishing work. There is a problem that it cannot be pulled out and pulled out. Also, when the fire hose is stored in the housing after the fire has been extinguished, it must be stored in a state of being wound around the inner wall surface of the housing, the winding range is large, and the hose rack must be suspended. Since the fire hose is fixed and cannot be stored, there is a problem that it takes a labor for storage work because it is detached from the hose rack.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a package-type fire extinguishing apparatus in which a fire hose can be easily pulled out and stored.

The present invention provides a fire extinguisher-filled container in a housing having an open / close door on the front, and a fire extinguisher from a fire-extinguishing nozzle provided at the distal end of the base end connected to the fire extinguisher-filled container and supplied with the fire extinguisher A fire extinguishing hose for spraying, wherein the fire extinguishing device includes a hose storage box for storing the fire hose wound in an inner winding in the housing, and the fire extinguishing hose is disposed at a lower portion of a side wall of the hose storage box. A package-type fire extinguisher having a notch for allowing the hose to escape to the outside .

  In this invention, the size of the storage box is smaller than the case where the fire extinguishing hose is stowed on the inner wall surface of the housing, and the fire hose is substantially fixed in close contact with the inner wall surface of the hose housing box by its own restoring force. Since it is stored in a state, the storing work becomes easy. Moreover, the fire hose can be pulled out smoothly during the fire fighting operation. Moreover, by providing the notch part in the lower part of the side wall of the hose storage box, the fire-extinguishing hose can be smoothly drawn out not only in the front but also in the left and right directions. This is because the cutout portion opens the force that the fire hose pushes the inner wall of the hose storage box outward (the force due to the hose pull-out force and the hose restoring force).

Embodiment 1 FIG.
FIG. 1 is a front view of a package-type fire extinguisher according to an embodiment of the present invention in a state in which an opening / closing door is opened, and FIG. 2 is a schematic cross-sectional view taken along line AA in FIG. FIG. 3 is a schematic cross-sectional view along the line BB. In addition, although the package-type fire extinguisher of FIG. 1 has shown the thing of the foam fire extinguisher which injects a foam-like fire extinguisher as an example, this application is not limited to this. In each figure, the housing 1 is a box-shaped housing having an opening 1a extending almost entirely on the front surface. The opening / closing door 2 covers the opening 1a on the front surface of the housing 1 so that it can be opened and closed, and the opening / closing fulcrum 2a faces from the front side to the back side of the housing 1 (= viewed from the front side of the housing). (The direction from the front side to the back side of the paper: hereinafter, the right and left and the winding direction of the hose are those seen from this direction), and is provided on the right side (on the side opposite to the hose storage box 6 described later). The extinguishing agent filling container 3 is a tank filled with a foam extinguishing agent as an extinguishing agent. The extinguishing hose 4 has a shape retaining performance, for example, a rubber hose whose cross section perpendicular to the length direction is a hollow circular shape, the base end of which is connected to the extinguishing agent filling container 3 side, and the extinguishing agent is supplied to the distal end Nozzle 5 is connected. The hose storage box 6 is provided on the left side of the housing 1 and houses the fire hose 4 and the fire extinguishing nozzle 5.

  The pressurization gas cylinder 7 is a tank filled with a pressurization gas, and the pressurization gas is released by operating the start valve 7 a, and the pressure regulator 9 adjusts the pressure of the pressurization gas. The pressurized gas introduction pipe 10 is a pipe for introducing the pressurized gas into the fire extinguisher filling container 3, and the discharge collecting pipe 11 is connected to the base end of the fire extinguishing hose 4, and is discharged from each fire extinguisher filling container 3. A foam fire extinguishing agent is introduced into the fire hose 4. The lever 5 a of the fire-extinguishing nozzle 5 connected to the tip of the fire-extinguishing hose 4 is a lever that is operated to release fire-extinguishing foam (extinguishing liquid) generated by the foam fire-extinguishing chemical from the fire-extinguishing nozzle 5. The fire-extinguishing nozzle 5 has a low-foaming water discharge section 5b that generates and discharges a low-foaming foam (low foaming), for example, a low foaming ratio of 5 to 20, for example, and a fire extinguishing ratio of 20 to 80, for example. And a middle foaming water discharge part 5c for generating and discharging foam (medium foaming).

  The hose storage box 6 is formed in a box shape having an open front, a hose introduction notch 6c is formed on the upper wall thereof, and a notch for smoothly pulling out a fire hose 4 (to be described later) on the lower side of the right side wall. A portion 6a is formed, and the opening on the front surface is folded back so that the fire hose 4 does not protrude from the opening except for the notch portion 6c and the notch portion 6a and the bottom wall portion. A portion 6b is formed. For example, as shown in a side view of the hose storage box 6 of FIG. 4 as viewed from the direction of the arrow C in FIG. And the hose storage box 6 is arrange | positioned at the left side surface side of the housing | casing 1 which is the opposite side to the opening / closing fulcrum 2a of the opening / closing door 2. As shown in FIG. A fire extinguisher filling container 3 having a substantially circular horizontal cross section is disposed on the right side of the hose storage box 6, and a pressurizing gas cylinder 7 is disposed on the right side thereof.

  The fire extinguishing hose 4 is introduced into the hose storage box 6 from the notch 6c for hose introduction, and is wound and housed in an inner winding counterclockwise from the back side of the hose storage box 6 toward the opening side. Yes. At this time, the fire extinguishing hose 4 is in a substantially fixed state in close contact with the inner wall surface of the hose storage box 6 by its own restoring force (restoring force that is wound by elasticity tries to return to the original straight state). It is stored. Here, “inner winding” refers to winding a wound object (for example, fire extinguishing hose 4) along the inner wall of a frame (for example, hose storage box 6).

  Next, the operation when the fire hose 4 is pulled out will be described. FIG. 5 shows an explanatory diagram for supplementing the explanation. When the fire extinguishing hose 4 stored as described above is pulled out from the hose storage box 6 in the forward direction, the force of pushing the inner wall surface of the hose storage box 6 due to the hose pull-out direction and the restoring force of the hose pulled out. Since the direction is different, the fire hose 4 can be pulled out smoothly.

  Further, when the fire hose 4 is pulled out to the left, the hose pulling direction at the left inner wall portion of the hose storage box 6 and the direction of the force pushing the inner wall surface of the hose storage box 6 due to the restoring force of the hose pulled out are determined. It is conceivable that the force by which the hose pushes the left inner wall surface of the hose storage box 6 outward (force by the hose pulling force and the hose restoring force) increases and the fire hose 4 cannot be pulled out smoothly. However, even if there is no notch 6a, as shown in FIG. 5 (a), when the hose on the right side and the lower inner wall of the hose storage box 6 is pulled out, the hose on the upper side of the hose storage box 6 Since the hose of the side inner wall part is pulled out by gravity and slides down due to gravity, the hose of the left inner wall part of the hose storage box 6 pushes the left inner wall surface of the hose storage box 6 outward. Is reduced and the hose 4 for fire extinguishing can be pulled out smoothly because the hose 4 is pulled out following the right and lower hoses.

  Further, when pulling out in the right direction, the direction of the hose pulling out direction at the right inner wall portion of the hose storage box 6 is the same as the direction of the force pushing the inner wall surface of the hose storage box 6 due to the restoring force of the hose pulled out. If the hose pushes the inner wall surface on the right side of the hose storage box 6 outward (force by the hose pull-out force and the hose restoring force) and the notch portion 6a is not present, the fire hose 4 as shown in FIG. Is pressed against the lower part of the right side wall of the hose storage box 6, and when the winding radius R of the hose becomes a predetermined value or less by further pulling operation, the hose is fixed in a kink (folded) state. It is conceivable that the fire hose 4 cannot be pulled out from the hose storage box 6. In the right inner wall portion, the hose in the lower side and the left inner wall portion following the hose does not change the force pushing the inner wall outward, so that it is fixed in a substantially kink state.

  However, by forming the notch 6a in the lower part of the right side wall of the hose storage box 6, the hose 4 is allowed to escape to the outside of the hose storage box 6 as shown in FIG. Can be kept larger, and the notch 6a allows the fire hose 4 to release the force that pushes the right side wall surface of the hose storage box 6 outward (due to the hose restoring force and the force to pull out the hose). The fire hose 4 can be pulled out smoothly without being fixed in the kink state. Even when the fire-extinguishing hose 4 is pulled out to the left by forming the notch 6a, the fire-extinguishing hose 4 is escaped from the notch 6a to the outside of the hose storage box 6 as shown in FIG. By doing so, the winding radius R of the hose can be kept larger, and the fire hose 4 can be pulled out more smoothly.

  In the notch 6a, the kink state of the fire extinguishing hose 4 often occurs. The opening side of the fire extinguishing hose 4 wound in the hose storage box 6 (the first and second rolls from the fire extinguishing nozzle 5) 4) and the strength of the hose storage box 6 are taken into consideration, as shown in FIG. 4, the width is wide on the opening side and narrows toward the back, and does not reach the back. It is preferable to form a trapezoid. The fire extinguishing hose 4 after the first or second winding is kinked in the hose storage box 6 by applying a force drawn from the back side in the hose storage box 6 toward the opening side when being pulled out. It is further prevented from being fixed in the state.

  In the package-type fire extinguisher configured as described above, when a fire occurs, the operator first opens the opening / closing door 2 and opens the start valve 7a. Then, the pressurized gas from the pressurized gas cylinder 7 is adjusted to a predetermined pressure by the pressure regulator 9 and introduced into each extinguishing agent filling container 3 through the pressurized gas introduction pipe 10. Then, the foam extinguishing agent in each extinguishing agent filling container 3 is introduced into the extinguishing hose 4 through the discharge collecting pipe 11. Next, the operator holds the fire-extinguishing nozzle 5 in his / her hand, pulls out the fire-extinguishing hose 4 from the hose storage box 6 and approaches the place where the fire occurs. At this time, the fire hose 4 is housed in the hose storage box 6 by being wound inwardly in the counterclockwise direction from the back to the opening side so that the fire-extinguishing nozzle 5 is on the opening side. Since the notch 6a is formed in the lower part of the right side wall of the hose storage box 6 and the fire extinguisher filling container 3 having a substantially circular horizontal cross section is provided on the right side of the hose storage box 6 so that a gap is formed on the right side of the notch 6a. It can be pulled out smoothly in both the front and left and right directions.

  Then, the operator operates the lever 5a from a location a little away from the beginning to discharge the fire-extinguishing foam (low foaming) from the low firing water discharge part 5b. When the fire is moderated to some extent, the fire is approached and the lever 5a is operated to release fire-extinguishing foam (medium foam) from the middle firing water discharge part 5c to extinguish the fire. After the fire is extinguished, the operator closes the start valve 7 a and the lever 5 a and stores the fire hose 4 in the hose storage box 6. At this time, since the hose storage box 6 is smaller than the housing 1, the fire hose 4 is easily opened in the hose storage box 6 so that the fire-extinguishing nozzle 5 is on the opening side (the base end side is the back). It can be accommodated so as to be wound inwardly counterclockwise toward the side. Then, the open / close door 2 is closed.

Embodiment 2. FIG.
Moreover, in said embodiment, since the hose storage box 6 was arrange | positioned along the left side surface of the housing | casing 1, the fire hose 4 can be drawn out smoothly, the housing | casing 1 size can be made small, etc. The fire hose 4 is stored in the hose storage box 6 counterclockwise, a notch 6a is formed in the lower part of the right side wall of the hose storage box 6, and the horizontal section is substantially circular on the right side of the hose storage box 6. The fire extinguisher filling container 3 is disposed and the opening / closing fulcrum 2a is set to be provided on the right side surface of the housing 1. However, when the hose storage box 6 is disposed along the right side surface of the housing 1, FIG. As shown in FIG. 6, the fire hose 4 is stored in the hose storage box 6 in the clockwise direction with the left and right and the clock / counterclockwise reversed, and a notch 6a is formed in the lower part of the left side wall of the hose storage box 6. The horizontal cross section on the left side of the hose storage box 6 has a substantially circular shape. Agent filled container 3 is arranged, closing supporting point 2a may be set to be provided on the left side of the housing 1. The operations, functions, effects, etc. are all the same as those described in the above embodiment except that the left and right and the clock / counterclockwise rotation are reversed.

Embodiment 3 FIG.
In the above embodiment, the hose storage box 6 and the open / close door 2 are provided on the left and right sides of the housing in consideration of the possibility that the fire hose 4 may be caught on the open / close door 2. The box 6 is provided on the bottom surface of the casing 1 having the same height as the lower end of the opening 1a of the casing 1 that is closed when the open / close door 2 is closed. Therefore, the height at which the fire hose 4 is drawn out is high. Since it is a very low position, even when the fire hose 4 is pulled out so as to pass through the lower side of the door 2, there is almost no possibility that the fire hose 4 will be caught on the door 2. Even if the opening / closing fulcrum 2a of the opening / closing door 2 is provided on the same side as the hose storage box 6 of the housing 1, as shown in FIG.

  As described above, in the package-type fire extinguisher of the present invention, the fire extinguisher filling container 3 and the base end are connected to the fire extinguishing agent filling container 3 in the housing 1 provided with the opening / closing door 2 on the front face, and the supply of the fire extinguishing agent is received. In a package-type fire extinguishing apparatus that houses a fire extinguishing hose 4 that injects a fire extinguishing agent from a fire extinguishing nozzle provided at the tip, a hose storage box that houses the fire hose 4 by winding it in the casing 1 6 was provided. As a result, the storage box size is reduced as compared with the case where the fire hose 4 is stored on the inner wall surface of the housing 1, and the fire hose 4 is placed on the inner wall surface of the hose storage box 6 by its own restoring force. Since it is stored in a closely fixed state, it can be stored easily, and even a single woman can store it. Further, it can be easily operated, and the fire hose 4 can be pulled out smoothly not only in the front direction but also in the left or right direction during the fire fighting operation.

  However, when the fire hose 4 is stored in the hose storage box 6 in the counterclockwise direction, the fire hose 4 can be pulled out smoothly in the left direction, but the fire hose 4 is in the right direction. It cannot be pulled out by the force pushing the left inner wall surface of 6 to the outside (force by hose pulling force and hose restoring force). When the fire hose 4 is stored in the hose storage box 6 in the clockwise direction, the fire hose 4 can be pulled out smoothly in the right direction, but the fire hose 4 is in the left direction. It cannot be pulled out by the force that pushes the left inner wall of the outside outward (force by hose pulling force and hose restoring force).

  Therefore, a notch 6 a is provided in the lower part of the side wall of the hose storage box 6. Thereby, the fire extinguishing hose 4 can be smoothly pulled out not only in the front but also in the left and right directions. This is because the notch 6a opens the force by which the fire hose 4 pushes the inner wall surface of the hose storage box 6 outward.

  Further, the hose storage box 6 is stored by winding the fire hose 4 counterclockwise when viewed from the front side of the housing, and is cut out at the lower side of the right side wall when viewed from the front side of the housing of the hose storage box 6. The part 6a is provided. Thereby, when the fire hose 4 is stored counterclockwise, the fire hose 4 can be smoothly pulled out in the right direction.

  Further, the hose storage box 6 is arranged along the left side as viewed from the front side of the casing 1 of the casing 1, and the horizontal section has a substantially circular shape on the right side when viewed from the front side of the casing of the hose storage box 6. The fire extinguisher filling container 3 was disposed. As a result, the extinguishing agent-filled container 3 has a substantially circular cross section, so that the extinguishing hose 4 pushes the right inner wall surface of the hose storage box 6 outward on the right side of the notch 6a of the hose storage box 6. The fire hose 4 can be smoothly pulled out in the right direction, and the fire hose 4 can release the force pushing the right inner wall surface of the hose storage box 6 outward. There is no need to set, and the size of the housing 1 can be minimized.

  Further, the hose storage box 6 is stored by winding the fire hose 4 in a clockwise direction when viewed from the front side of the casing, and the notch 6a is formed in the lower portion of the left side wall as viewed from the front side of the casing of the hose storage box 6. Was established. Thereby, when the fire hose 4 is housed clockwise, the fire hose 4 can be smoothly pulled out in the left direction.

  Further, the hose storage box 6 is disposed along the right side surface of the housing 1 when viewed from the front side of the housing, and the horizontal cross section is substantially circular on the left side when viewed from the front side of the housing of the hose storage box 6. A fire extinguishing agent filling container 3 was arranged. As a result, the extinguishing agent-filled container 3 has a substantially circular cross section, so that the extinguishing hose 4 pushes the left inner wall surface of the hose storage box 6 outward on the left side of the notch 6 a of the hose storage box 6. Since there is a space that can be opened, the fire hose 4 can be pulled out smoothly in the left direction, and the space where the fire hose 4 can release the force pushing the left inner wall surface of the hose storage box 6 outward is bothered. There is no need to do so, and the size of the housing 1 can be minimized.

  In addition, the opening / closing fulcrum of the opening / closing door 2 was provided on the side surface side of the housing 1 opposite to the hose storage box 6. Thereby, the opening / closing door 2 does not get in the way, the storing operation of the fire hose 4 can be easily performed, and the fire hose 4 can be pulled out smoothly.

  Further, the hose storage box 6 is provided on the bottom surface of the housing 1 that is closed when the door is closed, and the opening / closing fulcrum of the door 2 is provided on the side surface of the housing 1 on the same side as the hose storage box 6. It was. Since the hose storage box 6 is provided on the bottom surface of the casing 1 having the same height as the lower end of the opening 1a of the casing 1 that is closed when the open / close door 2 is closed, the height at which the fire hose 4 is drawn out is high. Since the fire hose 4 is hardly caught by the door 2, the opening / closing fulcrum 2 a of the door 2 and the hose storage box 6 are provided on the same side of the housing 1. Has the same effect.

  In the above-described embodiment, the foam extinguishing agent is used as the extinguishing agent. However, the present invention can be applied to a package type extinguishing apparatus using a powder extinguishing agent other than foam, and the same effect can be obtained. Moreover, although the inside of the fire extinguisher filling container 3 was in a non-pressurized state, the gas cylinder 7 for pressurization may be deleted as a pressure accumulation type, and in this case, gas may be used as the fire extinguishing agent. In this case, the start valve 7a and the pressure regulator 9 may be provided in the fire extinguisher filling container 3.
