Description

Description: TECHNICAL FIELD The present invention relates to a simulated fire extinguishing training apparatus capable of performing sufficient fire extinguishing training without using actual flames and digestive organs. [Background Art] The practice of fire extinguishing drills in disaster drills and the like is important without any particular explanation, and is carried out almost without exception. In firefighting training, training using actual fire extinguishers against actual flames requires a high cost for filling the used digestive tract with digestive agents, so it cannot be used in large quantities and is sufficient for many trainees. It was virtually impossible to conduct a proper training, which was not a satisfactory fire-fighting drill. In addition, the use of a powdery extinguisher causes inconvenience to surrounding residents, and therefore, it has been desired to provide a simulated fire extinguishing training device that can perform a convenient and satisfactory digestive training. Conventionally, there was an apparatus using light in the digestive apparatus as a simulated fire extinguishing training apparatus. However, when light was used, the place of use was limited to indoors where external light was small. In addition, as a simulated fire-fighting training device that can be used outdoors, there was a device that used a laser beam for the digestive system, but due to the nature of the laser beam, safety and handling difficulties such as having to keep it away from human eyes were found. There was. Also, the conventional simulated fire extinguishing training device
Because he simply turned his gastrointestinal tract at the picture that saw the flame, it was naturally impossible to elevate the trainee's willingness to train and to inform his / her skill in firefighting work. [Purpose] The purpose of the present invention is to be easy and safe to handle, to enhance the motivation of trainees to train them, and to achieve efficient fire extinguishing work. Moreover, they can be used repeatedly at low cost and have a simple structure. And to provide an inexpensive simulated fire extinguishing training device. [Structure] The object is that the apparatus according to the present invention is a fire extinguisher configured to emit an ultrasonic wave from an ultrasonic wave emitting device provided in a nozzle of a hose, and a state in which a fire is simulated by simulating a flame scenery. A simulated flame device that can change the scene, a sensor that detects ultrasonic waves emitted from the simulated digestive device, and a control device that controls the simulated flame device based on a signal input from the sensor. The simulated flame device includes a simulated flame member formed using a flexible material, and a blower that blows the simulated flame member so as to rise upward and causes the simulated flame member to perform a flame operation. A simulation fire extinguishing training device, wherein the control device controls an air volume that the blower sends to the simulation flame member. [Example] Next, an example of the present invention will be described with reference to the drawings. FIG. 1 shows a preferred embodiment of a simulated fire extinguishing training apparatus to which the present invention is applied. The simulated fire extinguishing training apparatus of the embodiment comprises a flame display device 1 and a fire extinguisher 2 and a trainee operates the flame display device 1. This is a fire extinguishing training device that allows trainees to perceive how long it takes to extinguish the simulated flame that appeared above by extinguishing the time required to extinguish it. A characteristic feature of the present invention is that a simulated flame and an ultrasonic wave are used instead of an actual flame and an extinguisher, and thus can be performed at a lower cost than training using an actual fire extinguisher. For this reason, the flame display device 1 includes a simulated flame 10 simulating an actual flame, a sensor 11 for detecting a signal from the fire extinguisher 2, a display 12 for displaying the time required for fire extinguishing, a sound of flame burning and a sound of the fire extinguisher. Is generated as a sound effect. FIG. 2 is a diagram showing the inside of a digestive organ. Fire extinguisher 2 has a battery 20 and a timer inside its body.
Having a control PCB 21 with a built-in 28 and an ultrasonic generator 22;
The nozzle 24 at the distal end of the hose 23 is provided with an ultrasonic emitting device 25 having a cylinder 25a for adjusting the spread of ultrasonic waves. Here, when the upper lever 26a and the lower lever 26b of the fire extinguisher are gripped and the upper lever is tilted in the direction of arrow A, the limit switch means 27 provided between the upper and lower levers is turned on, and this signal is transmitted to the built-in timer of the control PCB 21. Enter 28. When a signal is input from the switch means 27, the built-in timer 28 counts only while the switch means is ON, and drives the ultrasonic generator 22 for an integrated time of about 20 seconds. This is because the fire extinguisher capacity of the actual fire extinguisher is consumed in about 20 seconds and does not necessarily need to be 20 seconds. The signal generated by the ultrasonic wave emitting device 22 is transmitted through the inside of the hose 23 via the signal line 100, and is emitted to the outside through the ultrasonic wave emitting device 25 and the cylinder 25a provided at the tip of the hose 23. I do. In addition, a lamp 29 is provided on the front surface of the fire extinguisher main body as a remaining amount display device for displaying the remaining amount of the fire extinguisher. This lamp 29 lights when the integration time of the timer 28 is within 20 seconds,
Turns off after 20 seconds. It can be understood that the fire extinguisher has been used up by this extinguishing. When the user subsequently uses the fire extinguisher, the timer in the control PCB 21 is reset by pressing the reset switch 30 provided on the main body of the fire extinguisher, so that the user can use the fire extinguisher again for 20 seconds. FIG. 3 is a sectional view of the fire display device 1. The front surface of the flame display device 1 is covered with a transparent acrylic plate 80 to block external wind and the like. Reference numeral 81 denotes a background plate on which, for example, a picture of a kitchen is drawn. Reference numeral 83 denotes an outlet for removing the wind in the flame display device. A blower box 31 is formed at the lower part of the flame display device 1, and has an air inlet 32 formed by a cutout hole on the upper surface of the blower box 31 and an air inlet 33 at the bottom surface. I have. Blow port 32 above
The entire surface is covered with a wire mesh 34 or the like, and a bag-like simulated flame 10 made of nylon fabric is locked around the ventilation opening, and is usually placed on the wire mesh 34. A blower 35 is provided in the blower box 31 and the wind direction is the same as the simulated flame 10.
And the blower's rotation axis is blower box.
It is connected to the output shaft of the motor 36 fixedly instructed to the bottom surface of the base 31 so as to be able to blow air into the simulated flame 10 through the blower port 32 according to the rotation of the motor. On the front of the blower box 31, indicators B, C,
Are arranged at predetermined intervals. The above-described ultrasonic sensor 11, display 12, speaker 13, and motor 33 are connected to a control box 37 provided in the blower box, and all the operations are controlled by a control PCB 41 in the control box shown in FIG. In addition to the above, a remote control box 40 for controlling the operation of the flame display device 1 from a power source for driving a motor and the like in addition to the above.
(Shown in FIGS. 1 and 4) are connected. FIG. 4 is a block diagram of the control box 37. The remote control box 40 is provided with a reset switch 40a, a start switch 40b, and a stop switch 40c. When the reset switch 40a is pressed, the display 12 is reset and the flame display device 1 is in a training start preparation state. Next, when the start switch 40b is pressed, the operation of the flame display device 1 is started, and when the stop switch 40c is pressed, the operation is temporarily stopped and the elapsed time is displayed on the display 12. A power supply 42 is connected to the control PCB 41 so as to supply all necessary currents as a whole. The power supply 42 may be a DC power supply or an AC power supply. In the case of a DC power supply, necessary electric power is obtained from the outside through a battery of the power supply 42, and in the case of an AC power supply, necessary electricity is obtained from an external through an outlet. The control PCB 41 includes a reset switch 40a, a start switch 40b, and a fire extinguishing signal 1 from the sensor 11 as well as signal lines from the stop switch 40v provided on the remote control box 40.
10 is also input, and the control PCB 41 performs predetermined control based on the input signal. The above control is divided into operation control related to the operation of the flame display device input from the remote control box 40 and fire extinguishing program control based on an input signal from the sensor. First, the operation control will be described. Now, when the reset switch 40a of the remote control box 40 is pressed, this reset signal is input to the control PCB 41 via the signal line 120. The signal input to the control PCB 41 receives the predetermined control here, resets the previous time displayed on the display 12 to 0 seconds,
The motor 36 connected to the blower 35 is driven. As a result, the simulated flame 10 '' is colored red or the like by sending wind from the suction hole 33 on the lower surface of the blower to the simulated flame 10 locked on the blower box 31 through the air outlet 32 and controlling the amount of air blown. It is formed into a conical bag with a narrow end formed on a nylon base, and an air vent 10a for bleeding the internal air is appropriately provided in some places. By controlling the rotation of the blower in various ways, it is possible to produce the simulated flame 10 as if the flame were burning. The reset signal is controlled. The PCB drives the sound effect generation circuit 43 connected to the speaker 13 to generate a sound effect such as "go" as a flame sound as a flame sound.
Output to outside via. This sound effect is synchronized with the rotation speed of the motor 36, that is, the amount of air blown from the blower, and is configured such that the higher the flame height, the greater the sound output. In addition, in response to the input of the fire extinguishing signal 110 input from the sensor 11, a fire extinguishing sound such as "shear", that is, an effect sound of a fire extinguisher from the fire extinguisher is configured to be generated. The effect is visually similar to that of a fire fighting exercise using actual fire. Next, when the start switch 40b is pressed, the display on the display unit 12 is started via the control PCB 41, and 0 seconds, 1 second, 2 seconds, 3 seconds,...
... is displayed. The stop switch 40c is a switch for temporarily stopping the above operation. When the stop switch 40c is pressed, the display 12 is stopped while the time display on the display 12 is temporarily held. Next, fire extinguishing program control based on an input signal from the sensor will be described. Fire fighting program control PCB41 control
This is performed by a fire extinguishing program stored in a memory 41a provided therein. The fire extinguishing program is a flame display device 1.
The analysis is performed every two seconds from the time when the ultrasonic wave is applied to the three sensors A, B, and C provided on the front surface of the motor, and the rotation speed of the motor for the next two seconds is determined. In the embodiment, the sensors are arranged such that A is located at the left end of the front surface of the flame display device, B is located at the center, and C is located at the left end. Then, the input from the sensor arranged in this way is picked up, and X = (detection time of sensor B) − (detection time of sensor A) − (detection time of sensor C)... The rotation speed of the motor 36 is controlled in accordance with the detection result, and the amount of air blown by the blower 35 is controlled. In the embodiment, the number of rotations of the motor 36 is set to four modes of (high-H) (medium-M) (low-L) (stop-S), and the detection result of the above equation (1) is obtained. When X = (0-0,6 or 0-0-0,6) seconds, the L mode is: X = (0,7-1,2 or -0,7--1,2) seconds,
At the time of M mode, X = (1, 3 to 2, 0 or -1, 3 to -2, 0) seconds,
At this time, the H mode is determined and the rotation speed of the motor 36 is controlled. When none of the sensors detect, the H mode is selected. Thus, the flame is reduced when an appropriate fire extinguishing operation is performed, and eventually the fire is extinguished. However, if the extinguishing operation is not appropriate, the flame is further increased. Next, when an attendant describing actual training using the present device presses the reset switch 40a of the remote control box 40, the control PCB 41 resets all operations. That is, display 1
The extinguishing time of 2 is reset to 0 seconds, and the simulated flame 10 in the flame display device 1 comes up from the speaker 13 with a sound effect of “go”, and it appears as if the flame was burning. Here, the attendant gives a signal to "start fire extinguishing" and at the same time presses the start switch 40b. Along with this signal, the trainee holds the fire extinguisher 2 placed in a predetermined place, pulls the safety plug 90, looks at the nozzle 24 at the fire source, and turns the upper lever toward the sensor 11.
Hold the lower lever 26a to start fire fighting. As described above, when the upper and lower levers of the digestive apparatus are gripped, the switch means 27 provided between the upper and lower levers is turned on, so that the nozzle 24
The ultrasonic wave is emitted from the ultrasonic wave emitting device 25 provided in the speaker 13, and a sound effect “shear” is emitted from the speaker 13. When the fire is extinguished with the nozzle evenly directed to the base of the flame, the flame gradually becomes smaller. When the fire is completely extinguished, the sound effect and the fire extinguishing time of the indicator 12 are stopped, and the time for the fire extinguisher is displayed blinking. By recording this time in some form, the trainee can compare the time for the fire extinguisher with other trainees. It is to learn the fire extinguishing work. In the present embodiment, three sensors A, B, and C have been described, but the present invention is not limited to this.
If the number is equal to or more than the number, any number may be provided, and the fire extinguishing program may be changed to an appropriate one. In the present embodiment, a simulated fire extinguisher simulating a lever-type fire extinguisher has been described, but it is needless to say that the present invention can also employ a simulated fire extinguisher simulating another type of fire extinguisher. For example, when a simulated fire extinguisher imitating a fall-type fire extinguisher is adopted, the simulated fire extinguisher may be inverted to emit ultrasonic waves from an ultrasonic emitting device provided on a hose nozzle. . [Effects] As described above, according to the present invention, instead of the actual flame, a simulated flame formed by using a flexible material that changes from a state of burning to a state of extinguishing by controlling the amount of air blown from a blower is used. Because it uses ultrasonic waves instead of digestives, it can be easily used by anyone indoors and outdoors, and it is possible to conduct fire-fighting training that is safe, easy, and close to fire-fighting work in actual fires You can do it. Furthermore,
The simulated fire extinguishing training device of the present invention has a very simple structure as described above, and is inexpensive.
