Description

  The present invention relates to a fire extinguisher for a mobile building, and more particularly, in the event of a wildfire, a fire extinguisher is installed to prevent a fire from spreading to a remote building such as a cultural property or temple. The present invention relates to a fire extinguishing apparatus for a mobile building that can be easily moved, can form a water film around a building, prevent a fire, or perform a fire extinguishing work in a place where a fire has occurred.

  In general, in the event of a fire, use a powder fire extinguisher (including a foam fire extinguisher) to inject a fire extinguishing agent filled into the fire source (hereinafter referred to as the fire source), or to a fire hydrant. After connecting the hose, high pressure water supplied from the fire hydrant was directly injected into the fire source to suppress the fire.

  Recently, with the development of technology, when a fire breaks out, it is detected immediately, and using an automatic fire extinguishing equipment such as a sprinkler arranged so that water is jetted from the ceiling surface of a building, etc. Improved fire suppression.

  On the other hand, when a fire breaks out, the fire is generally suppressed using water and foam liquid, and sprinklers and water injection devices are used as equipment for this purpose. The range is limited, and it is unsuitable for extinguishing fires such as fires in large buildings and forest fires. In particular, it has been difficult to suppress a wide range of oil and gas fires.

  Therefore, diversified efforts and research for improving such problems have been advanced, and recently, a method capable of suppressing a fire using fog has been proposed.

  According to the fire suppression method using mist, fine water particles are ejected in the form of a mist toward the fire source, and the principle that the fire source can be suppressed by the cooling action in parallel with the suffocation action is applied.

  In other words, fine water particles form a mist layer between the fire source and the external air, suffocate the fire source, and the water particles below the mist layer cool while instantaneously evaporating by the fire source. That is.

  Such a fog jet fire extinguishing system has already been applied to several fire fighting facilities after a verification stage.

  However, the conventional mist jet fire extinguishing system or fire fighting equipment to which this is applied lacks the ability to inject mist to a wide or distant location, and is mostly used in a fixed manner for the purpose of fire suppression in buildings. However, in order to compensate for the insufficient injection capacity, there is a problem that a large number of forced air blowers and drain heads must be provided.

  In particular, national treasure-class temple cultural properties are usually in the mountains, so even a fire truck equipped with various fire-fighting facilities takes a long time until the fire engine is dispatched and the fire is subdued. It is necessary and often burned out, and the current situation is that the fire prevention measures are not clear.

  In addition, since such cultural assets are usually made of wood, there is a problem that once the fire is ignited by a fire type flying on a leaf or the like from the mountains, it is burned out at high speed.

  Also, if it fails to extinguish the fire in the initial stage within 5 minutes after the occurrence of the fire, a huge fire damage occurs, and once it is wrapped in flames due to the characteristics of the temple cultural property, the fire is extinguished with a fire truck. However, there was a fatal weakness that many cultural assets were burnt down.

  As a result, in the temple cultural property, the initial fire suppression and protection from fire is the key.

  Background art of the present invention is disclosed in Patent Document 1 (published July 1, 2009, title of invention: upward water discharge fire extinguishing device for protection of temple cultural property).

  In the prior art, a general building fire extinguisher is installed together with piping so that water can be jetted into or out of the building, so it is not easy to install the fire extinguishing device. There was a problem that it was difficult to save time and cost.

  In addition, general building fire extinguishing equipment is always exposed inside or outside the building and is easily damaged by climate change and user's carelessness. There was a problem that normal maintenance and repair management were necessary.

  In addition, since general fire extinguishing equipment is fixed around and inside buildings, there is a problem that it is difficult to perform fire extinguishing work if a fire occurs in a building where no fire extinguishing equipment is installed. It was.

It is the perspective view which showed the flow-path main body and the conversion valve.

  Referring to FIGS. 1 to 5, a fire extinguishing apparatus for a mobile building according to an embodiment of the present invention includes a movable cabinet 30 provided with a wheel 32, a connection provided in the cabinet 30 and extended from the fire hydrant 10. A connection supply hole 34 to which the hose is coupled is provided, and is provided in communication with at least two of the flow path main body 50 in which a plurality of flow paths are formed and the flow path of the flow path main body 50. , Drainage heads 54a and 56a that scatter water supplied from the flow path body 50, a fire hose 70 that extends from the flow path body 50 and is housed inside the cabinet 30, and the flow path body 50. A water supply valve 58 a that adjusts the supply and non-supply of water supplied to the fire hose 70.

  A fire hydrant 10 is provided around a building such as a cultural property or temple in the mountains or remote areas. The fire hydrant 10 is connected to a supply pipe extending from a water source, and the connecting hose extended from the fire hydrant 10 is The connection supply hole 34 is detachably connected.

  Therefore, when a fire such as a forest fire occurs, the operator connects the connection hose to the connection supply hole 34, moves the cabinet 30 to the periphery of the building, and then opens the main valve 52- The water supplied to the flow path body 50 is made to scatter from the drain heads 54a and 56a.

  Since the water splashed by the drain heads 54a and 56a forms a water film around the building, it is possible to prevent a fire from occurring in the building.

  After the fire has occurred in the building, it is necessary to concentrate water on the site where the fire has occurred and to inject water. At this time, when the operator opens the water supply valve 58a, the water supplied from the flow path body 50 Is also supplied to the fire hose 70 side, the operator can inject water into the site where the fire has occurred with the pipe rod 72 while injecting water from the drain heads 54a, 56a.

  In the present embodiment, as described above, the fire extinguishing device can be easily moved close to the building, so that fire extinguishing work can be performed in a short time, and a water film is formed around the building by the drainer heads 54a and 56a. At the same time, water can be sprayed concentrated on the fire site.

  Therefore, it becomes possible to perform a quick and effective fire extinguishing work after a fire approaches a building in a mountain or a remote place, or after the fire has occurred.

  The flow channel body 50 has a connection supply hole portion 34 formed at one end thereof, and the first flow channel 54 and the second flow channel 56 so that the water flowing in along the connection supply hole portion 34 branches. , And a third flow path 58, and the first flow path 54 is formed with a narrower cross-sectional area than the second flow path 56.

  When the operator opens the water supply valve 58 a, water is supplied to the third flow path 58, and water can be injected from the fire hose 70 to the fire site in a concentrated manner, depending on whether the conversion valve 80 is operated or not. When water is supplied to one of the first flow path 54 and the second flow path 56, a drainer head 54 a provided in communication with the first flow path 54 and the second flow path 56, A water film is formed while water scatters from 56a.

  The flow path body 50 is provided with a conversion valve 80 that opens one of the first flow path 54 and the second flow path 56 and closes the other, and the third flow path 58 includes a water supply valve 58a. Is provided.

  Further, the drainer heads 54 a and 56 a are a first drainer head 54 a provided in communication with the first channel 54 and a second drainer head 56 a provided in communication with the second channel 56. And have.

  When fire extinguishing work using the fire hose 70 is not required, the operator operates the conversion valve 80 to supply water to the second flow path 56 having a relatively large cross-sectional area, so the second drainer head Water is scattered from 56a.

  When fire extinguishing work using the fire hose 70 is required, when the operator opens the water supply valve 58a and operates the conversion valve 80 to close the second flow path 56, the water flows into the first flow path. 54 is supplied to the first drain head 54 a and is supplied from the third flow path 58 to the fire hose 70.

  At this time, since the water supplied to the flow channel body 50 is branched and supplied to the first flow channel 54 and the third flow channel 58, the flow pressure of the water supplied to the first flow channel 54 side. However, since the first channel 54 has a narrower cross-sectional area than the second channel 56, the flow rate of the water passing through the first channel 54 becomes faster, Can be prevented from decreasing.

  Therefore, even during a fire extinguishing operation using the fire hose 70, a fluid pressure similar to that at the time of supplying water through only one flow path of the second flow path 56 is formed inside the first flow path 54. Therefore, a water film can be formed around the building by the water supplied from the first flow path 54.

  The conversion valve 80 is slidably provided on the inlet side of the first flow path 54 and the second flow path 56, and the passage hole portion 82 a allows water supplied to the first flow path 54 to pass therethrough. The shield panel 82 formed on the channel body 50 and the shield panel 82 projecting to the outside of the channel body 50 are slidably housed. And an operation handle 84 whose rotation shaft is screwed into the case 86.

If it arrange | positions facing this flow path 56, the other side of the interruption | blocking panel 82 will close the 2nd flow path 56, and only the 1st flow path 54 will be open | released.

  On the other hand, when the blocking panel 82 projects outside the flow channel body 50, the other side of the blocking panel 82 closes the first flow channel 54 and opens the second flow channel 56.

  The rotation shaft of the operation handle 84 is rotatably connected to the blocking panel 82, and the rotation shaft of the operation handle 84 is formed with a screw thread and screwed into the case 86. When rotated in the direction or in the opposite direction, the blocking panel 82 is moved while the rotation shaft of the operation handle 84 appears or disappears inside or outside the case 86.

  Hereinafter, the operation of the mobile building fire extinguishing apparatus according to one embodiment of the present invention configured as described above will be described.

  When a fire such as a forest fire occurs, the operator connects the connection hose of the fire hydrant 10 to the connection supply hole 34, moves the cabinet 30 to the periphery of the building, and then opens the cover of the cabinet 30. The main valve 52 is opened.

  Accordingly, the water supplied from the fire hydrant 10 flows into the flow channel body 50, passes through the second flow channel 56, and forms the water film around the building through the second drainer head 56a. Prevent fires from occurring on objects.

  In addition, the water film formed around the building blocks the oxygen supplied to the flame and extinguishes the fire, and the water is bound to the building while the building is cooled. Therefore, there is an effect of preventing the occurrence of fire.

  When concentrated injection of water is required at the fire site due to the occurrence of a fire, when the operator opens the water supply valve 58a, the water flowing into the flow path body 50 is supplied to the third flow path 58, and the fire fighting is performed. Water is sprayed along the hose 70 in the direction of the pipe rod 72 adjusted by the operator.

  Therefore, while forming a water film around a building, water can be concentrated and sprayed to a fire site.

  At this time, when the operator turns the operation handle 84 to project the blocking panel 82 to the outside of the flow channel body 50, the second flow channel 56 is blocked and the first flow channel 54 having a relatively small cross-sectional area. Since the water is supplied to the first drain head 54a, the flow rate of the water supplied to the first drain head 54a is increased, and the water pressure of the water forming the water film is prevented from being lowered.

  Therefore, while forming a water film around a building, it is possible to simultaneously perform a fire extinguishing operation of concentrating on a fire site and injecting water.

  FIG. 6 is a perspective view showing a flow path body and a conversion valve of a fire extinguishing apparatus for a mobile building according to another embodiment of the present invention.
