DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the volcano simulator according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a volcano simulator according to the present invention. This volcano simulator is installed outdoors as a monument, and can represent, for example, a volcano erupting or lava flowing down from the summit to the slope.

In this volcano simulator, upward gas burners 11 and 13 of different sizes are installed at the top and the foot of the volcano model 1, and a plurality of downward gas burners 12 are installed on the hillside. Volcano model 1
Is made in the same color and shape as the original volcano, and is constructed so that it will not be damaged when exposed to wind and rain. The gas burners 11 to 13 are variously controlled by the control device 60 as described later.

FIG. 2 shows the structure of the upward gas burner 11 installed on the top of the model 1. This gas burner 11 is suitable for emitting a flame upward and has an opening 33
A plurality of combustion cylinders 22 are erected at the center of the outer cylinder 21 provided with. The upper end of the combustion cylinder 22 is opened as a flame outlet 23. A manifold 24 is attached to the lower side of the combustion cylinder 22, and combustion gas is ejected from the nozzle 25 of the manifold 24 into the combustion cylinder 22. A combustion gas supply pipe 26 is connected to the manifold 24, through which combustion gas is supplied from an external combustion gas supply device (not shown). An open / close solenoid valve 40 for stopping the supply of combustion gas is attached to the combustion gas supply pipe 26.

A part of the ejection port 23 of the combustion cylinder 22 is cut out, and a pilot burner 27 is inserted therein. Combustion gas is supplied to the pilot burner 27 from an external combustion gas supply device through a pipe 38.
A solenoid valve 39 for opening and closing for stopping combustion gas is attached to the pipe 38. Further, as shown in FIG. 3, an ignition rod 28 and a thermocouple 29 are also inserted in the cutout portion of the ejection port 23. The ignition rod 28 is for igniting the bilot burner 27, and the thermocouple 29
When the flame of the pilot burner 27 is extinguished, is for detecting this and stopping the supply of combustion gas. The pilot burner 27, the ignition rod 28, and the thermocouple 29 are provided on the support frame 3 that is erected around the combustion cylinder 22.
It is attached to 0.

Further, as shown in FIG. 2, an air supply cylinder 31 connected to an external air supply source (not shown) is erected on the side of the combustion cylinder 22, and a nozzle hole 32 is provided at the tip thereof. It is provided. Air is ejected from the nozzle holes 32 to fill the inside of the outer cylinder 21, and passes through above the combustion cylinder 22 and is discharged to the outside from the opening 33. The air flow is horizontal above the combustion tube 22, and the combustion gas ejected upward from the ejection port 23 is laterally blown and mixed.

With this, the combustion gas and the air are sufficiently mixed. Therefore, even if the mixing ratio is arbitrarily changed, the fuel can be completely burned, and thereby, it is possible to generate a flame suitable for viewing, for example, an orange flame or a flame having a color similar to lava. This upward gas burner 11 does not require a suction hole for the primary air, and therefore can prevent backfire and is safe.

A cylindrical wind shield 34 is erected around the opening 33 of the outer cylinder 21, and water drops and the like are prevented from entering above the jet port 23 of the combustion cylinder 22. A plate 35 is provided. Further, since the outer ring 36 is attached to the outside of the windshield 34 and the top plate 35, it can be used as it is without an attached transparent cover even outdoors exposed to the wind and rain. The gas burner 11 is fixed to the model 1 by legs 37.

Next, the downward gas burner 12 attached to the slope of the model 1 will be described. FIG. 4 shows the configuration of the downward gas burner 12. The downward gas burner 12 is suitable for discharging the flame from the horizontal direction to directly below, and here, for convenience of description, the case of discharging the flame in the horizontal direction will be described.

In the downward gas burner 12, a combustion gas supply cylinder 42 is horizontally arranged in the center of a burner case 41 which is substantially sealed. The tip of the combustion gas supply cylinder 42 is sealed, and a plurality of nozzle holes 4 are provided on the side surface slightly inside from the tip.
3 are provided at equal intervals. Combustion gas is supplied to the combustion gas supply cylinder 42 from an external combustion gas supply device through a gas pipe 44. A strip-shaped windshield 45 is provided upright in front of the nozzle hole 43 so that the combustion gas ejected from the nozzle hole 43 is not blown off even if wind is blown from the outside.

Further, a bowl-shaped flame diffusing portion 46 is attached to the tip of the combustion gas supply cylinder 42. With this, the flame is diffused and emitted, and the wind blown from the outside causes the wall surface of the flame diffusing portion 46. It is supposed to bounce along. This makes it possible to prevent the flame from extinguishing due to external influences.

Behind the nozzle hole 43, the burner case 4 is provided.
An air rectifying plate 47 for partitioning 1 into front and rear is attached, and a large number of round holes 48 are provided in this. And
The air supplied to the rear of the air rectifying plate 47 from the air supply pipe 49 connected to the lower side of the burner case 41 has a round hole 48.
It is ejected through the nozzle hole 43 side. by this,
Air is blown from the side of the combustion gas ejected from the nozzle holes 43 and is sufficiently mixed. Therefore,
There is no need to provide a primary air suction hole in the combustion gas supply cylinder 42, and this can prevent flashback, which is safe.

Immediately above the nozzle hole 43, one ignition rod 50 and three thermocouples 51 for detecting when the flame is extinguished are attached. When it disappears, the supply of combustion gas is stopped. The flame generated here is discharged to the outside from a tapered mouthpiece 52 attached to the front end of the burner case 41.

In this gas burner 12, as shown in FIG. 5, a gas pipe 44 connected to the combustion gas supply cylinder 42 is divided into two parts, and one pipe 44A has a flow rate adjusting valve 5
3 and an opening / closing solenoid valve 54A are attached. Also,
Only the opening / closing solenoid valve 54B is attached to the other pipe 44B. Then, when the gas burner 12 is started to be used, the combustion gas whose flow rate is adjusted by the flow rate adjusting valve 53 as a pilot burner is supplied to the combustion gas supply cylinder 42 from one of the pipes 44A, and this is supplied to the nozzle hole 43.
Erupted from. At the same time, the ignition rod 50 operates to ignite the combustion gas. As a result, the nozzle hole 4
A flame as a pilot burner is emitted from 3.

And, in case of releasing the ornamental flame,
Open / close solenoid valve 5 attached to the other pipe 44B
4B is opened, and a predetermined amount of combustion gas is supplied and ejected from the nozzle hole 43. This is ignited by the flame previously emitted as the pilot burner, and the original ornamental flame is generated and is emitted from the base 52.

In the downward gas burner 12, the combustion gas and the air are separately supplied, so that the mixed gas having a mixing ratio necessary for generating a flame having a color suitable for viewing and a flame having a color similar to lava is provided. It can be easily generated and is sufficiently mixed even if the amounts of combustion gas and air are changed, so that flames of various sizes can be generated. Further, since the windshield 45 and the burner case 41 are provided, it can be used as it is even in the outdoors where the weather is strong. The downward gas burner 12 is directly fixed to the slope of the model 1 downward in this example.

The gas burner 13 attached to the bottom of the mountain of the model 1 has almost the same structure as the gas burner 11 attached to the top of the model 1 and is manufactured in a small size.

As described above, the gas burners 11 to 13 used here are capable of generating a flame of a color suitable for viewing, for example, an orange flame or a flame similar to lava, and the size of the flame is large. It can also be adjusted arbitrarily. In addition, it can be used as it is without a transparent cover even in windy and rainy outdoors. Further, each gas burner 11-13 is individually controlled as described below.

The ignition sequence and combustion duration of the gas burners 11 to 13 are separately set as will be described later.
It is set to an arbitrary pattern by the burner controller 61 within 0. FIG. 6 shows the burner controller 61. In the figure, when the automatic / manual switch 62 is set to the manual side, various patterns can be manually set. Then, when the automatic / manual switch 62 is switched to the automatic side after the pattern is set, the operation is started according to the set pattern.

By operating the fan switch 63, an external air source such as a fan (not shown) is started or stopped. In this example, the gas burners 11 to 13 are not ignited when the fan is stopped. This is to prevent the raw gas from being released.

Further, in this volcano simulation device, the operation patterns of the gas burners 11 to 13, that is, the operation start time, operation end time, operation continuation time, operation interval, each gas burner 1
It is possible to arbitrarily set the ignition order of 1 to 13 and the intervals thereof. For these settings, each item is selected by the item selection switch 64, and the contents are set by the rotary dip switch provided inside the burner controller 61. The item being set is displayed by the display lamp 65. The power switch 66 is provided at the right end.

The set contents are displayed in the time display section 67.
It will be displayed in, so if you check this and it is wrong, you can set it again. Which of the gas burners 11 to 13 is used can be selected by the burner switch 68. Also, the power supply, the fan, and the gas burners 11 to 1
The ignition rods 28 and 50 of No. 3 are connected to the connection terminal 69 provided on the surface of the burner controller 61.

In this volcano simulation device, the gas burner 1 first installed on the top by the procedure described below.
It is possible to set 1 to ignite, then the gas burners 12 attached to the slopes in order from the top, and finally the gas burners 13 attached to the foot of the mountain to ignite. It is possible to express the appearance of a stream flowing from the top toward the foot of the mountain. At this time, the flame emitted from each of the gas burners 11 to 13 can have a color similar to that of lava, so that the effect as a monument can be further improved.

FIG. 7 is a flow chart showing the procedure of the operation setting process 70 for each of the gas burners 11-13. First, the automatic / manual switch 6 of the burner controller 61
When 2 is set to the manual side, the present time lamp is turned on (step 71). Next, the current time is set by the internal rotary dip switch (step 72). Next, when the item selection switch 64 is pushed up, the start time lamp is turned on (step 73). Then, the operation start time of the gas burners 11 to 13 is set by the rotary dip switch (step 74).

Similarly, by operating the item selection switch 64 and the rotary dip switch, the operation end time, the lighting continuation time, the lighting and lighting interval time, the lighting sequence of the gas burners 11 to 13 and the differential time thereof can be set. Set (steps 75 to 82). After completing all the settings, the automatic / manual switch 62 is switched to the automatic side (step 83). This operation setting process 7
0 ends. With this setting, when the operation start time comes, flames having a color similar to lava are emitted from the gas burners 11 to 13 in a predetermined order, and a state in which the lava flows down as described above is expressed.

Here, the ignition system and safety measure system of this volcano simulator will be described with reference to FIG. As shown in the figure, a control circuit 90 is connected to a burner controller 61 for controlling the ignition timing and the combustion duration of the gas burners 11 to 13, where the opening / closing solenoid valve control circuit 91 and the high voltage generation circuit are connected. 92, the alarm device 93, and the flame detection circuit 94 are controlled.

In this control system, the burner controller 61
When the ignition command of the pilot burner in the gas burners 11 to 13 is input from the control circuit 90 to the control circuit 90, the opening / closing solenoid valve 39 of the pipe 38 is first opened in the gas burners 11 and 13 arranged at the top and the periphery. Combustion gas is ejected from the burner 27. At the same time, the ignition rod 28 operates to ignite the combustion gas, which causes the pilot burner 27 to emit a flame.

In this way, after the pilot burner 27 is ignited, the thermocouple 29 produces an electromotive force due to its heat and outputs the voltage V. Here, since three thermocouples 29 are connected in series, the voltage is 3
It becomes V. This is detected by the flame detection circuit 94, where it is converted to an appropriate level and supplied to the control circuit 90. Then, the control circuit 90 controls the opening / closing solenoid valve control circuit 91.
Is controlled, and the solenoid valve 39 for opening and closing is kept open by an instruction from here. This is pilot burner 27
The flame is constantly emitted from.

Further, in the gas burner 12 installed on the hillside, a suitable combustion gas as a pilot burner is supplied to the combustion gas supply cylinder 42 from one gas pipe 44A, and this is ejected from the nozzle hole 43. At this time, the ignition rod 50 operates to ignite the combustion gas. As a result, the flame as a pilot burner is released. In this gas burner 12 as well, after the pilot burner is ignited in the same manner as described above, this is detected by the thermocouple 51, whereby the opening and closing of the solenoid valve 54A for opening and closing is maintained, and the flame of the pilot hana is constantly released. become.

Next, when ignition of the ornamental flame is instructed from the burner controller 61 at a predetermined timing, the solenoid valves for opening and closing the combustion gas supply pipe 26 in the upward gas burners 11 and 13 installed at the top and the foot of the mountain. 40 is opened so that combustion gas is supplied to the combustion cylinder 22 and the ejection port 2 is opened.
Eject from 3. This combustion gas is the pilot burner 2
It is ignited with a flame of 7, which emits an ornamental flame.

In the downward gas burner 12 installed on the hillside, the solenoid valve 54B for opening and closing the other pipe 44B.
Is opened, a predetermined amount of combustion gas is supplied to the combustion gas supply cylinder 42, and this is ejected from the nozzle hole 43. This combustion gas is ignited by the flame previously emitted as a pilot burner, which emits an ornamental flame.

Now, for example, when the by-lot burner 27 of the gas burners 11 and 13 installed at the top and the bottom of the mountain disappears for some reason, the temperature near the thermocouple 29 decreases, and the electromotive force of the thermocouple 29 disappears. The voltage V output from the device will be lost. This is detected by the flame detection circuit 94 and transmitted to the opening / closing solenoid valve control circuit 91 via the control circuit 90.
As a result, a closing signal is output from the opening / closing solenoid valve control circuit 91 to close all the opening / closing solenoid valves 39, 40 of the gas burners 11, 13. At this time, an alarm can be issued using an alarm device 93 such as a buzzer or a display lamp.

Similarly, the gas burner 12 installed on the hillside
When the flame of the pilot burner is extinguished, this is detected by the thermocouple 51, whereby the opening / closing solenoid valves 54A, 54B are closed and the supply of combustion gas is stopped. At this time also, the alarm device 93 can issue an alarm.

As described above, in this volcano simulation device, when the flame of the pilot burner in each of the gas burners 11 to 13 is extinguished, the supply of combustion gas for pilot burner and for ornamental use is stopped, so that raw gas is directly output. It is safe because it can be prevented from being spouted into the air. In addition,
In each gas burner 11-13, the thermocouple 29,5
Since three 1's are attached, even if one of the thermocouples 29, 51 becomes inoperable, it can be reliably detected by the other thermocouples 29.51 when the flame disappears. It is even safer.

The volcano simulator should be equipped with fog fountains, means for expressing waterfalls, rivers, etc., or means for generating various sound effects such as volcanic eruption sounds and bird squeals. Is also possible. As a result, the effect as a monument can be further improved.
