Detailed Description
The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
Fig. 1 to 5 show embodiment 1 of the present invention. The fire training apparatus a of this embodiment has an apparatus main body 1. The apparatus main body 1 is made of a metal plate excellent in heat resistance and corrosion resistance such as stainless steel, and is formed in a rectangular box shape with an open upper portion as shown in fig. 1 to 3. The inside of the apparatus main body 1 is a housing portion 1 a. Water, which is a kind of nonflammable liquid, is contained in the container portion 1a at a predetermined depth. The apparatus body 1 may be formed in a square shape, a circular shape, or the like by etching, as long as the upper portion is opened. The liquid contained in the containing section 1a may be a liquid other than water, and may be nonflammable.
A pair of casters 2, 2 is provided at one end in the longitudinal direction (left end in fig. 1; hereinafter referred to as a front end) of the lower surface of the apparatus body 1. The pair of casters 2, 2 are disposed at both ends of the short-side direction of the front end of the apparatus main body 1. The caster 2 has a wheel 2 a. The wheel 2a is rotatable about a horizontal axis extending in the short side direction of the apparatus body 1.
At the other end portion (right end portion in fig. 1; hereinafter referred to as a proximal end portion) in the longitudinal direction of the lower surface of the apparatus body 1, a pair of support shafts 3, 3 are provided. The support shafts 3, 3 are disposed at both ends of the apparatus main body 1 in the short direction. The support shaft 3 is disposed with its longitudinal direction oriented in the vertical direction, and its upper end is fixed to the lower surface of the apparatus main body 1. The lower end surface of the support shaft 3 is flush with the lower end edge of the wheel 2 a. Therefore, when the lower end surfaces of the support shafts 3 and 3 are placed on a horizontal floor or the like, the apparatus body 1 is horizontally supported by the casters 2 and the support shafts 3 and 3. The position of the apparatus body 1 is fixed by frictional resistance acting between the lower end surfaces of the support shafts 3, 3 and the ground or the like. On the other hand, the device body 1 can be easily moved by the casters 2 and 2 by slightly lifting the base end portion of the device body 1 and separating the support shafts 3 and 3 from the floor or the like.
A window hole 1b penetrating the sidewall is formed at the proximal end of the sidewall along the longitudinal direction of the apparatus body 1. The window hole 1b allows outside air to flow into the housing portion 1a when combustion gas is combusted, as described later. The window hole 1b has a function of keeping the water level of the water contained in the container 1a constant, in addition to the function of taking in the air. That is, when the water level of the water contained in the containing portion 1a is located above the lower end edge of the window hole 1b, the water in the upper side flows out from the window hole 1 b. Thus, the water level of the water contained in the container 1a is maintained at the same level or lower than the lower edge of the window hole 1 b. The window hole 1b is formed in a rectangular shape, but may be formed in a square shape or a circular shape. In addition to the window holes 1b, the window holes 1b may be provided at the distal end portions of the side walls extending in the longitudinal direction or the side walls extending in the short-side direction.
A gas discharge pipe 4 is provided inside the housing portion 1 a. As shown in fig. 4, the gas discharge pipe 4 is disposed in the center of the apparatus body 1 in the short-side direction, with its long-side direction oriented in the long-side direction of the apparatus body 1. As shown in fig. 1, the front end portion (left end portion in fig. 1) of the gas discharge pipe 4 is supported on the bottom wall of the apparatus main body 1 via a bracket 5. The other end of the gas discharge pipe 4 is supported by a sidewall on the base end side of the apparatus main body 1 via a pipe 6 described later.
As shown in fig. 1, the gas discharge pipe 4 is disposed below the lower edge (water surface) of the window hole 1b so as to be immersed in the water contained in the containing portion 1 a. The peripheral wall of the gas discharge pipe 4 is provided with discharge holes (not shown) penetrating the peripheral wall. Therefore, when the combustion gas is supplied to the gas discharge pipe 4, the combustion gas is discharged into the water through the discharge hole. The combustion gas released into the water floats in the water and comes out upward from the water surface. The combustion gas coming out of the water surface is ignited by a flame species described later and continuously burned. At this time, the air outside the apparatus body 1 is introduced into the housing portion 1a through the window hole 1 b. As the combustion gas discharged into the water from the gas discharge pipe 4, the same combustion gas as used in the conventional fire-fighting training device, for example, LP gas, is used.
As shown in fig. 1 to 4, a plurality of gas burners 7 are provided inside the housing portion 1 a. As shown in fig. 4, the gas burners 7 are disposed apart from each other on both sides of the gas discharge pipe 4 and on a straight line parallel to the gas discharge pipe 4. The gas burners 7 disposed on one side with respect to the gas discharge pipe 4 and the gas burners 7 disposed on the other side are disposed so as to be alternately arranged in the longitudinal direction of the gas discharge pipe 4 (the longitudinal direction of the apparatus main body 1). The gas burners 7 need not necessarily be arranged as described above, and may be arranged so as to be separated from each other in the circumferential direction on one circumference.
The gas burner 7 has a burner body 7 a. The burner main body 7a is formed in a cylindrical shape, and is disposed with its axis directed in the vertical direction. The burner body 7a has a lower end closed by a bottom and an upper end opened. The lower end of the burner main body 7a is disposed above the water surface. That is, the entire burner main body 7a is disposed above the water surface. The burner body 7a does not necessarily have to be entirely located above the water surface, and the lower end portion may be located below the water surface. On the other hand, the upper end surface of the burner main body 7a is located slightly below the upper end surface of the apparatus main body 1. The upper end surface of the burner main body 7a may be flush with the upper end surface of the apparatus main body 1, or may be located above the upper end surface of the apparatus main body 1.
The lower end of the burner main body 7a is supported on the bottom wall of the apparatus main body 1 via a support pipe 8. The support pipe 8 not only fixes the burner body 7a to the apparatus body 1, but also functions as a gas pipe for supplying gas to the gas burner 7. As shown in fig. 4, a nozzle hole 7b is formed in the center of the lower end of the burner main body 7 a. The nozzle 7b communicates with the support pipe 8. Therefore, when gas is supplied to the support pipe 8, the gas is discharged upward from the nozzle holes 7b into the burner main body 7a, and further discharged upward from the upper end opening of the burner main body 7 a. The gas discharged upward from the burner main body 7a is ignited by the combustion flame of the combustion gas floating on the water surface.
When the gas discharged from the burner body 7a is burned, the height of the combustion flame from the water surface is higher than the height of the flame when the gas discharged from the gas discharge pipe 4 into the water and floating out of the water surface is burned. Therefore, the gas burner 7 of this embodiment satisfies the following two conditions. These two conditions are not necessarily satisfied at the same time, and either one may be satisfied. The conditions for making the height of the combustion flame generated by the gas burner 7 higher than the height of the combustion flame generated by the gas floating on the water surface are not limited to these two conditions.
The 1 st condition is that the flow rate of gas per unit area of gas discharged from the upper end opening of the burner main body 7a and the flow rate of gas per unit area of gas floating on the water surface are the same, and the upper end of the burner main body 7a is disposed above the water surface. In this way, the combustion flame of the gas discharged from the burner main body 7a is higher than the combustion flame of the gas floating on the water surface by the amount that the upper end of the burner main body 7a is positioned above the water surface. The amount of gas discharged per unit area from the burner body 7a may be slightly smaller than the flow rate of gas floating on the water surface, and the height of the combustion flame of the gas burner 7 may be higher than the combustion flame floating on the water surface.
The 2 nd condition is that the flow rate of gas per unit area of gas discharged from the upper end of the burner main body 7a is made larger than the flow rate of gas per unit area of gas floating on the water surface. The following two methods are used as methods for satisfying this condition. One method is to change the concentration of the gas. In this embodiment, the configuration is such that: the inner diameter of the nozzle hole 7b is set to be larger than the inner diameter of the release hole formed in the gas release pipe 4, and the concentration of the gas released from the upper end opening of the burner main body 7a is richer than the concentration of the gas floating out of the water surface. In another method, the flow velocity of the gas discharged from the burner main body 7a is made higher than the flow velocity of the gas floating on the water surface.
A plurality of air intake ports 7c penetrating the peripheral wall of the burner main body 7a are formed at the lower end of the burner main body 7 a. The air intake port 7c is disposed further downward than the upper end of the nozzle hole 7 b. When gas is discharged from the nozzle holes 7b, air in the housing portion 1a is drawn into the burner body 7a through the air intake port 7 c. As a result, the gas discharged from the burner main body 7a is burned in a good state. The air intake port 7c may be disposed at a position equivalent to the upper end of the nozzle hole 7b, or may be disposed above the nozzle hole 7 b.
The gas is supplied to the gas discharge pipe 4 and the gas burner 7 as described below. That is, the header member 9 is provided at the base end portion of the surface of the apparatus main body 1. The header member 9 is connected to a control unit CU via a pipe 10, and the control unit CU is connected to a gas supply device G. The control unit CU is controlled by a controller C. That is, when a combustion button (not shown) of the controller C is operated, the control unit CU is in an open state. The combustion gas of the gas supply device G is supplied to the header member 9 via the control unit CU and the pipe 10.
One end of the support pipe portion 6a of the pipe 6 is connected to the header member 9. As shown in fig. 1 and 2, the intermediate portion of the support tube portion 6a is supported by the side wall on the proximal end side of the apparatus main body 1 in a penetrating state. An intermediate portion of the three-way branch pipe 6b is connected to a front end portion of the support pipe portion 6a that enters the inside of the apparatus main body 1, that is, the inside of the housing portion 1 a. Inside the three-way branch pipe 6b, a gas passage (not shown) extending in the vertical direction is provided. The support pipe portion 6a is connected to an intermediate portion in the vertical direction of the gas passage. The upper end of the gas passage communicates with an ignition port (not shown) formed at the upper end of the three-way branch pipe 6 b. The ignition port is arranged above the water surface. The base end of the gas discharge pipe 4 is connected to the lower end of the gas passage of the three-way branch pipe 6b via an elbow 6 c. Therefore, when the combustion gas is supplied to the header pipe member 9, a part of the combustion gas is discharged upward from the ignition port, and a part of the combustion gas is discharged into the water from the gas discharge pipe 4.
As shown in fig. 1, 2, and 5, the header member 9 is connected to one end of each of the communication tubes 11 as many as the number of the gas burners 7. The other end portions of the communication pipe 11 are connected to the lower end portions of the support pipes 8. Therefore, when the combustion gas is supplied to the header member 9, a part of the combustion gas is supplied to each gas burner 7 through the communication pipe 11 and the support pipe 8.
As shown in fig. 1, 2, and 5, protective wall portions 1c, 1c extending in the longitudinal direction of the apparatus body 1 are provided at both ends in the short-side direction of the lower surface of the apparatus body 1. As shown in fig. 5, protective wall portions 1c, 1c are disposed such that header member 9 and communication pipe 11 are located therebetween. Thereby, header member 9 and communication pipe 11 are protected. It is preferable that the protective wall portions are provided between the distal end portions and the proximal end portions of the protective wall portions 1c and 1c, respectively.
As shown in fig. 1 and 2, an ignition device 12 is provided at the base end of the device body 1. The ignition device 12 has a cover 12 a. The cover 12a is provided at the proximal end portion of the apparatus body 1 and is disposed such that one end portion (left end portion in fig. 1) thereof covers the proximal end portion of the apparatus body 1 from above. One end of the cover 12a is open downward, and communicates with the base end of the housing 1a through the open portion. Therefore, when gas is released into the water through the gas release pipe 4, a part of the gas enters the one end of the cover 12 a. One end of the cover 12a is vertically opposed to the ignition port.
An ignition plug 12b is provided in one end portion of the cover 12 a. The ignition plug 12b is connected to the control unit CU via an igniter 12 d. When the operation such as pressing the combustion button of the controller C is performed, the current for ignition is intermittently supplied from the control unit CU to the ignition plug 12b for a certain time (for example, 10 seconds). Then, spark discharge is generated between the pair of electrodes 12c, 12c (see fig. 3) of the ignition plug 12 b.
As is apparent from fig. 1 and 2, the electrodes 12c, 12c of the ignition plug 12b are arranged substantially directly above the ignition port. Therefore, when a current is applied to the ignition plug 12b while a part of the combustion gas is discharged upward from the ignition port by the operation of the combustion button of the controller C, the combustion gas discharged upward from the ignition port is ignited by spark discharge between the electrodes 12C, and is continuously burned as a flame. As can be seen, in this embodiment, the ignition device is constituted by the ignition device 12 and the ignition ports of the three-way branch pipes 6 b.
A part of the combustion gas supplied to the header pipe member 9 is supplied to the gas discharge pipe 4 via the pipe 6. The combustion gas supplied to the gas discharge pipe 4 is discharged into the water through the gas discharge pipe 4, floats on the water, and comes out upward from the water surface. The combustion gas floating upward above the water surface is ignited by the ignition seeds and burned.
The remaining part of the combustion gas supplied to the header pipe member 9 is supplied to the gas burner 7 via the communication pipe 11. The combustion gas supplied to the gas burner 7 is discharged upward from the burner body 7 a. The combustion gas is ignited by a combustion flame of the combustion gas floating out of the water surface. As can be seen, in this embodiment, the combustion flame of the combustion gas floating on the water surface is used as the 2 nd ignition device for igniting the combustion gas discharged from the gas burner 7.
The controller C is provided with an adjustment switch, and the amount of the combustion flame and the height thereof can be adjusted by adjusting the adjustment switch to increase or decrease the supply amount of the combustion gas to the header member 9. The combustion of the combustion gas is variously controlled by the controller C, but the control contents and methods thereof are not important in the present invention, and the contents and methods may be the same as those of known control contents and methods, and therefore, the description thereof is omitted.
In the fire training apparatus a having the above configuration, when the combustion button of the controller C is operated, the combustion gas is supplied to the header member 9. A part of the combustion gas supplied to the header member 9 is discharged upward from the ignition port. At the same time, spark discharge is generated between the electrodes 12c, 12c of the ignition plug 12 b. The combustion gas discharged from the ignition port is ignited by the spark discharge, and becomes a flame to be continuously burned.
A part of the combustion gas supplied to the header part 9 is discharged into the water from the gas discharge pipe 4. The combustion gas floats in the water and comes out upward from the water surface. Then, the ignition is initiated by the ignition species, and the combustion flame is continuously burned. The height of the combustion flame is substantially constant at each portion in the horizontal direction.
The remaining portion of the combustion gas supplied to the header assembly 9 is supplied to the gas burner 7 through the communication pipe 11. The combustion gas supplied to the gas burner 7 is discharged upward from the upper end opening of the burner body 7 a. Then, the combustion gas is ignited by the combustion flame of the combustion gas emitted from the water surface, and the combustion is performed. The height of the combustion flame from the gas burner 7 from the water surface is higher than the height of the combustion flame from the water surface. Therefore, the height of the combustion flame emerging from the housing portion 1a in the entire housing portion 1a is different for each portion in the horizontal direction. Therefore, the person who performs the fire-fighting experience can perform the fire-fighting operation in a state close to the actual fire, and more meaningful fire-fighting experience can be realized.
Next, another embodiment of the present invention will be described. In the following embodiments, only the configurations different from those of the above-described embodiments will be described, and the same reference numerals are attached to the same portions as those of the above-described embodiments, and the description thereof will be omitted.
Fig. 6 is a plan view showing embodiment 2 of the present invention. In this embodiment, a plurality of branch pipes 4a are provided in the gas discharge pipe 4. All the branch pipes 4a extend from the gas discharge pipe 4 in a direction orthogonal thereto. Some of the full manifolds 4a extend from the gas discharge pipe 4 toward one side portion side (upper side in fig. 6). The branch pipes 4a are disposed so as to be alternately arranged in the longitudinal direction of the gas discharge pipe 4 with respect to the gas burners 7 disposed on the same side. The remaining branch pipes 4a extend from the gas discharge pipe 4 toward the other side portion side (lower side in fig. 6). The remaining branch pipes 4a are disposed so as to be alternately arranged in the longitudinal direction of the gas discharge pipe 4 with respect to the gas burners 7 disposed on the same side.
Fig. 7 is a plan view showing embodiment 3 of the present invention. In this embodiment, a gas discharge pipe 4A is used instead of the gas discharge pipe 4. The gas discharge pipe 4A is arranged to extend annularly along the inner surface of the side wall portion of the apparatus main body 1, and all the gas burners 7 enter the interior divided by the gas discharge pipe 4A. In this embodiment, the gas discharge pipe 4 of the embodiment shown in fig. 1 to 5 or the gas discharge pipe 4 and the branch pipe 4a shown in fig. 6 may be combined.
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
For example, in the above-described embodiment, the ignition ports, the gas discharge pipes 4, and the gas burners 7 are supplied with the combustion gas from one fuel supply source constituted by the gas supply device G and the control unit CU, but instead of the pipes 10, three pipes may be provided in the control unit CU, and the pipes may be connected to the ignition ports, the gas discharge pipes 4, and the gas burners 7, respectively. Accordingly, the supply amounts of the gas to be supplied to the ignition port, the gas discharge pipe 4, and the gas burner 71 can be individually adjusted. Instead of the pipe 10, two pipes may be provided in the control unit CU, one pipe may be connected to the ignition port and the gas discharge pipe 4, and the other pipe may be connected to the gas burner 7. In the case of such a configuration, the portion of the gas supply device G and the control unit CU that supplies the combustion gas to the pipe connected to the gas discharge pipe 4 becomes a combustion gas supply source to the gas discharge pipe 4, and the portion that supplies the combustion gas to the pipe connected to the gas burner 7 becomes a combustion gas supply source to the gas burner 7.
In the above-described embodiment, the combustion flame of the combustion gas floating on the water surface is used as the ignition device (the 2 nd ignition device) for igniting the combustion gas discharged from the gas burner 7, but as the ignition device for igniting the combustion gas discharged from the gas burner 7, an ignition device such as the ignition plug 12b may be provided in the apparatus main body 2 in the gas burner 7 or in the vicinity thereof. By combining such a configuration with a configuration in which gas supply sources to the gas discharge pipe 4 and the gas burner 7 are separately provided, three combustion systems, that is, a system in which only the combustion gas discharged into water from the gas discharge pipe 4 is combusted, a system in which only the combustion gas discharged from the gas burner 7 is combusted, and a system in which the combustion gases discharged from both the gas discharge pipe 4 and the gas burner 7 are combusted at the same time can be invented as the combustion system of the combustion gas.
