Description

The present invention relates to a fire extinguishing system and a water discharge gun device for extinguishing a fire by discharging water from a water discharge gun, a water discharge simulation method for the water discharge gun device, a water discharge direction adjusting method, and a water discharge direction confirmation method.

Conventionally, as a water discharge gun device for extinguishing a fire by discharging fire extinguishing water in a relatively wide space with a high ceiling such as a gymnasium as a protective zone, for example, the one shown in FIG. 14 is known.

As shown in FIG. 14, the water discharge gun device 200 is installed by embedding the device main body 202 in a wall surface having a height of, for example, about 4 meters overlooking the floor surface of a gymnasium or the like, and is exposed on the wall surface of the device main body 202. A fire detection unit 204 is provided on the upper part of the front panel, and a water discharge gun 206 is provided below the fire detection unit 204.

The fire detection unit 204 optically scans the detection optical axis from the infrared detection element with respect to the protection zone in the vertical direction within the range of the detection window formed in the vertical direction of the detection unit main body, and horizontally scans the fire detection unit 204. The fire in the protected area is monitored by rotating scanning.

Further, the water discharge gun 206 is located behind the water discharge gun cover in a steady state and is housed in the device main body 202, and the fire detection unit 204 detects infrared rays from the fire source 210 due to the fire in the protected area to determine the fire. Then, the direction of the fire source 210 is specified, the water discharge gun 206 is swiveled forward and directed toward the fire source 210, and in the automatic mode, when a predetermined automatic water discharge condition is determined, the water discharge indicated by the water discharge pattern 208 is discharged. It starts, and in the case of manual mode, water discharge is started when the water discharge start switch is operated.

In this case, the turning control of the water discharge gun 206 stops the fire detection unit 204 that has been horizontally scanned at the horizontal position where the fire source 210 is detected and vertically scans, and fires the water discharge gun 206 by the fire detection unit 204. The horizontal scanning angle at which the source 210 is detected is set as the target value, and the footback control is performed so that the deviation from the turning angle detected by the turning angle detector (rotary encoder) provided in the water discharge gun 206 is zero. 206 is directed in the detection direction of the fire source 210.

By the way, in the normal monitoring state, the fire detection unit 204 moves the horizontal scanning range of, for example, 180 ° on the front side in steps of, for example, 1 °, and moves vertically from 0 ° downward to 90 ° horizontally for each step movement. The fire is monitored while scanning.

Therefore, when installing the water discharge gun device 200, after installing the water discharge gun device 200 on the wall surface of the protected area, the water discharge gun 206 is manually swiveled, for example, the water discharge gun 206 is oriented in the front direction orthogonal to the wall surface. That is, the fire detection unit 204 is performing adjustment work to set the detection angle of the turning angle detector provided on the water discharge gun 206 to 90 ° in the direction in which the horizontal scanning angle is halved to 90 °.

Japanese Unexamined Patent Publication No. 08-038647 Japanese Unexamined Patent Publication No. 06-000229 Japanese Unexamined Patent Publication No. 06-031009 Japanese Unexamined Patent Publication No. 10-258136 JP-A-2002-291923

However, in the work of adjusting the turning detection angle of such a conventional water discharge gun, the operator stands at a front position separated by the water discharge distance from the water discharge gun device 200 and turns by manual operation. When the 206 turned to himself, he gave a signal to stop and turned to the front, and because it was an artificial judgment, the accuracy was poor, and the water discharge gun 206 could not be turned to the front correctly. In this state, since the detection angle of the turning angle detector provided on the water discharge gun 206 is set to 90 °, there is a problem that the error between the turning angle of the water discharge gun 206 and the fire detection angle by the fire detection unit 204 becomes large. ..

The present invention provides a fire extinguishing system and a water gun device capable of accurately recognizing the direction of the water discharge center line with respect to the protection zone of the water gun and adjusting the direction of the water discharge gun in a horizontal direction and the detection angle of the fire detection unit. It is an object of the present invention to provide a water discharge simulation method, a water discharge direction adjustment method, and a water discharge direction confirmation method of a water discharge gun device.

(Basic effect)
The present invention includes a fire detection unit that detects a fire in a protected area, a water discharge gun device that supports a water discharge gun so as to rotate horizontally, and a control that directs the water discharge gun in the fire detection direction detected by the fire detection unit. In a fire extinguishing system equipped with a unit, the water discharge gun device is provided with a beam scanning device that projects a beam light that horizontally coincides with the water discharge center line of the water discharge gun and scans vertically to a protected area. Since the control unit drives the beam scanning device in a predetermined operating state to project the beam light onto the protected area and display the emission line corresponding to the water discharge center line, the beam scanning device is used on the floor or wall surface of the protected area. The bright line obtained by the rotary scan or the swing scan of the projected beam light can visually and accurately know the direction in the horizontal plane to which the water discharge gun is currently facing.

(Effect of beam light scanning in water discharge)
The control unit operates the beam scanning device in a state where the water discharge gun is discharged in the direction of the fire detection detected by the fire detection unit, and projects the beam light from the water discharge gun to the water curtain sprayed on the protected area by discharging water to the water discharge center. Since the vertical plane passing through the line is displayed, the beam light hits the water curtain that falls on the protected area due to the water discharged from the water discharge gun, and the water curtain shines like a curtain, for example, in the dark at night or in the daytime. When water is discharged from the water, the lighting that acts as a curtain of light makes it possible to reliably grasp the state of the water discharge, and by looking at this, it is possible to increase the confidence in the water discharge by the water discharge gun.

In addition, when the observer manually directs the water discharge gun toward the fire source, the beam scanning device is operated to display the emission line due to the vertical rotation scanning of the beam light on the protection zone, so that the emission line is displayed as the fire source. By turning and stopping according to the above, the water discharge gun can be accurately and surely pointed at the fire source, and when the water discharge operation is started, the water can be reliably discharged to the fire source.

(Effect of beam rotation scanning by drive source)
The beam scanning device was mounted and fixed under the water discharge gun, and faced the opening window of the device housing and the tubular device housing in which the opening window was formed in the direction of the vertical plane passing through the water discharge center line of the water discharge gun.

A beam light source unit that incidents beam light on the reflecting surface from the horizontal direction, and a driving unit that is provided inside the device housing and rotationally drives the optical reflecting member at a predetermined speed to rotate and scan the beam light emitted from the opening window in a vertical direction. By realizing the beam scanning device as a compact tubular device, it can be properly installed in the space under the water discharge gun, and there is almost no need to change the water discharge gun device side. , It is possible to provide a beam scanning device and utilize it.

Further, when a laser light source is used for the beam light source unit by rotating and scanning the beam light vertically by the rotation of the optical reflection member, for example, the mirror member by the drive unit, the laser output exceeds, for example, 1 mW and causes harm to humans. Even if the level of effect is reached, when the movement of the laser spot is rotationally driven at, for example, 30 rps, which can be recognized as a bright line by a person, the laser light is not fixed irradiation but moving irradiation, so that the person receives it by direct irradiation of the laser light. The energy of the laser light is greatly reduced, for example, a bright line can be seen when traveling in the air. For example, even with a laser light source with an output exceeding 200 mW, the bright line can be displayed in the protected area without causing any harm to humans. It can also be applied to a water discharge gun with a water discharge distance of more than 100 meters.

(Effect of beam rotation by manual operation)
The beam scanning device is mounted and fixed to the underside of the water discharge gun, and has an opening window formed in the direction of the vertical plane passing through the water discharge center line of the water discharge gun, and the device housing is horizontal inside the device housing facing the opening window. An optical reflection member that is rotatably arranged around the axis and vertically reflects beam light incident from the horizontal direction by a reflection surface and emits from an opening window, and an optical reflection member provided in the device housing and provided on the reflection surface of the optical reflection member. An operation unit that rotates the optical reflection member to rotate the beam light emitted from the opening window vertically by operating the beam light source unit that incidents the beam light from the horizontal direction and the adjustment operation unit provided outside the device housing. Since it does not require a drive source such as a motor, the configuration is simple and the cost is low, and the bright spots to be used for confirmation when the water discharge gun is pointed accurately in the front direction are displayed in the protective section. By doing so, it is possible to perform an adjustment operation for setting the turning detection angle of the water discharge gun so as to match the fire detection angle when the fire detection unit faces the front.

(Effect of blinking beam light)
Further, the beam scanning device makes it possible to display a broken line or a moving broken line on the floor surface or the wall surface of the protected area by projecting the beam light while blinking it.

(Effect of light / dark change of beam light)
Further, the beam scanning device makes it possible to change the brightness of the emission line displayed on the floor surface or the wall surface of the protected area as needed by projecting while changing the intensity of the beam light.

(Effect of two-color beam light)
In addition, since the beam scanning device has different colors of the beam light at the time of water discharge and the beam light other than at the time of water discharge, for example, a red beam light is projected at the time of water discharge to call attention, while it is below the time of water discharge. In the case of, a green beam light is projected so that it can be distinguished from the time of water discharge.

(Effect of beam light projection during turning or before water discharge)
In addition, since the control unit drives the beam scanning device to project the beam light onto the protected area when turning to the fire point or before the water is discharged, the general facility users should be warned of the water discharge. Is possible.

(Effect of water gun device)
The effect of the water discharge gun device is the same as that in the case where the beam scanning device is provided in the water discharge gun device of the fire extinguishing system described above.

(Overview of fire extinguishing system)
FIG. 1 is an explanatory diagram showing an outline of a fire extinguishing system provided with a water discharge gun. As shown in FIG. 1, the fire extinguishing system includes a water discharge gun device 10, a field operation panel 12, a unit control panel 14, a master control panel 16, a self-fire alarm receiver 18, a fire detector 20, a pump control panel 22, and a fire extinguishing pump. It is composed of equipment 24, a water supply pipe 26, and a simultaneous release valve 28 using an electric valve, and an example is taken when two systems of water discharge gun devices 10 are installed in a protective section.

The operation of the fire extinguishing system is as follows. The water discharge gun device 10 monitors the fire by two-dimensionally scanning the protected area by scanning the fire detection unit, and when it detects infrared rays from the flame of the fire source, it stops the monitoring scanning at that position and indicates the direction of the fire source. A fire detection signal including data is transmitted to the unit control panel 14. Based on the fire detection signal, the unit control panel 14 swivels the water discharge gun of the water discharge gun device 10 toward the fire source to complete the preparation for water discharge.

Subsequently, the unit control panel 14 performs water discharge control, and this water discharge control includes an automatic water discharge mode, a semi-automatic water discharge mode, and a manual water discharge mode.

When the automatic water discharge mode is set on the master control panel 16 or the on-site operation panel 12, the unit control panel 14 is installed in the protection zone in addition to the fire detection signal from the fire detection unit of the water discharge gun device 10. When a fire transfer signal is received from the self-fire alarm receiver 18 that has received the fire detector 20, it is determined that the automatic water discharge condition has been satisfied, and after a predetermined time countdown, a pump start signal is sent to the pump control panel 22. Is sent to start the fire extinguishing pump of the fire extinguishing pump equipment 24, an open control signal is sent to the simultaneous release valve 28 to control the opening, and water discharge from the water discharge gun of the water discharge gun device 10 is started.

When the water discharge is started, the unit control panel 14 activates a timer for which a predetermined water discharge time is set, and when the time is up, the simultaneous release valve 28 is closed and controlled to stop the water discharge. Subsequently, the unit control board 14 resumes fire monitoring scanning by a fire detector of the water cannons device 10, if the fire detection is performed, since it is the case, such as blazed again after water discharge, to fire detection direction The water discharge gun is swiveled and controlled to restart water discharge. If no fire is detected even after the fire monitoring scan is started, the unit control panel 14 enters the normal condition monitoring.

In addition, since the automatic water discharge mode is usually performed in an unmanned state, the manager who received the fire report goes out to judge the situation at the site and confirm the fire extinguishing, and then manually operate the fire extinguishing pump equipment. Restoration such as suspension of 24 is performed.

When the semi-automatic water discharge mode is set on the master control panel 16 or the on-site operation panel 12, the unit control panel 14 swivels the water discharge gun of the water discharge gun device 10 toward the fire source based on the fire detection signal to prepare for water discharge. After the above is completed, the water discharge operation signal of the on-site operation panel 12 or the master control panel 16 is received and the water discharge from the water discharge gun is started.

In the water discharge operation by the on-site operation panel 12 or the master control panel 16, the observer inserts a key into the manual water discharge switch provided on the operation panel to operate the water discharge position. The unit control panel 14 that received the water discharge operation signal by this manual water discharge operation sends a pump start signal to the pump control panel 22 to start the fire extinguishing pump of the fire extinguishing pump equipment 24, and sends an open control signal to the simultaneous release valve 28. Open control is performed, and water discharge from the water discharge gun of the water discharge gun device 10 is started. When the observer confirms that the fire has been extinguished, the manual water discharge switch of the on-site operation panel 12 or the master control panel 16 is operated to the water discharge stop position, and in response to this, the unit control panel 14 closes the simultaneous release valve 28 to stop the water discharge. In addition, the fire extinguishing pump equipment 24 is manually restored such as stopping.

When the manual water discharge mode was set on the master control panel 16 or the on-site operation panel 12, the observer who confirmed the fire turned the water discharge gun of the water discharge gun device 10 by, for example, operating the on-site operation panel 12. A key is inserted into the manual water discharge switch toward the fire source to operate the water discharge position, and the unit control panel 14 sends a pump start signal to the pump control panel 22 to extinguish the fire of the fire extinguishing pump equipment 24 in response to the water discharge operation signal. The pump is started, an open control signal is sent to the simultaneous release valve 28 to control the opening, and water discharge from the water discharge gun of the water discharge gun device 10 is started. When the observer confirms that the fire has been extinguished, the manual water discharge switch of the on-site operation panel 12 is operated to the water discharge stop position, and in response to this, the unit control panel 14 closes the simultaneous release valve 28 to stop the water discharge. In addition, the fire extinguishing pump equipment 24 is manually restored such as stopping.

[Water discharge area and beam scanning of water discharge gun device]
(Water discharge pattern of water discharge gun)
FIG. 2 is an explanatory view showing a water discharge area of a water discharge gun and a bright line display by a beam scanning device. As shown in FIG. 2, the water discharge gun device 10 is installed at a predetermined height of a wall surface in a protected area such as a gymnasium, and a fire in the protected area is monitored by two-dimensional scanning of a fire detection unit 34. When the fire detection unit 34 detects a fire, the water discharge gun 30 is swiveled in the direction of the fire source to discharge water, and as shown in the water discharge pattern 120, the specified amount of water per unit time is within a predetermined width within a predetermined water discharge distance. Water is discharged.

(Overview of beam scanning device)
In the present embodiment, the beam scanning device 48 is provided under the water discharge gun 30. The beam scanning device 48 projects the beam light of a laser that horizontally coincides with the water discharge center line of the water discharge gun 30 and vertically rotates or swings, and corresponds to a projected image of the water discharge center line. The emission line 122 is displayed on the floor surface or the wall surface of the protected area, which makes it possible to visually and accurately know the direction in which the water discharge gun 30 is currently facing.

The display of the emission line 122 on the protected area is such that the beam light projected from the beam scanning device 48 is blocked by the opening window and the water discharge gun 30, so that even if the beam light is rotationally scanned around the vertical axis, it is actually directly below. The emission line 122 is displayed by scanning so as to include at least the outer edge of the water discharge area S, which is the maximum water discharge distance from the point P of.

(Beam scanning while water discharge is stopped)
In the display of the emission line 122 by the beam scanning of the beam scanning device 48, for example, when the water discharge gun device 10 is installed, an appropriate mark is attached to a point Q which is the front of the water discharge gun device 10 and separated by the maximum water discharge distance, and this mark is used. The water discharge gun 30 is manually swiveled and positioned so that the emission line 122 due to the rotational scanning of the beam light passes through, which makes it possible to accurately point the water discharge gun 30 in the front direction.

In this state, by performing an adjustment operation to set the turning detection angle of the turning angle detector (rotary encoder) provided on the water discharge gun 30 so as to match the fire detection angle when the fire detection unit faces the front. By reducing or eliminating the error in the horizontal detection angle between the fire detection unit 34 and the water discharge gun 30, the water discharge gun 30 is accurately swiveled and controlled in the direction of the fire detection angle detected by the fire detection unit 34 to move toward the fire source. It is possible to extinguish a fire reliably by discharging fire extinguishing water.

Further, as another usage of the beam scanning device 48, the beam scanning device 48 is operated while the water discharge gun 30 is swirled by manual operation to display the emission line 122 by the vertical rotation scanning of the beam light in the protection zone, thereby discharging water. A display corresponding to a water discharge simulation by the gun 30 becomes possible, and it is possible to grasp the state of water discharge by the water discharge gun 30 as a real feeling without actually discharging water.

Further, in the manual water discharge control when the manual water discharge mode is set, when the observer points the water discharge gun 30 toward the fire source, the beam scanning device 48 is operated to display the emission line 122 by the vertical rotation scanning of the beam light. By displaying it on the protected area, the emission line 122 can be swiveled and stopped so as to match the fire source, so that the water discharge gun 30 can be accurately and surely aimed at the fire source, and water discharge is started by the water discharge operation. If this happens, the water can be reliably discharged to the fire source.

(Beam light scanning in water discharge)
Further, as a usage of the beam scanning device 48, when the water discharge gun 30 is swiveled in the fire detection direction detected by the fire detection unit 34 to discharge water, the beam scanning device 48 is operated to discharge water from the water discharge gun 30 to a protected area. A beam light is projected onto the spraying water discharge pattern 120, and the beam light hits the water curtain that falls on the protected area by the water discharge from the water discharge gun 30, and the water curtain shines like a curtain. For example, it looks dark even at night or in the daytime. When water is discharged inside, the state of water discharge can be surely grasped by the lighting that serves as a curtain of light, and it is possible to increase the confidence in the water discharge by the water discharge gun 30 by seeing this.

[Overview of water gun device]

A water discharge gun cover 36 having a built-in water discharge gun is provided in the.

In the fire detection unit 34, a conical swivel scanning unit 38 is rotatably arranged horizontally under the semi-cylindrical overhanging portion, and the swivel scanning unit 38 is provided with a detection window 40 in the vertical direction. ing. Inside the fire detection unit 34, a scanning optical system including an infrared sensor and a rotating mirror that vertically scans the detection optical axis with respect to the protected area of the infrared sensor is built.

Therefore, the fire detection unit 34 sets the detection optical axis from the infrared detection element with respect to the protected area within the range of the detection window 40 formed in the vertical direction of the swirl scanning unit 38, for example, from 0 ° horizontally to 90 ° downward.
