Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher for extinguishing a fire generated in a large space with a water cannon.

[0002]

2. Description of the Related Art A fire extinguisher using a water cannon is known as one of disaster prevention systems for wide spaces such as factories, exhibition halls, indoor stadiums, and arenas in buildings. For example, the waste pit for temporarily storing the waste before incineration at the refuse incinerator has a large rectangular parallelepiped shape with length, width, and height ranging from ten meters to several tens of meters. Various miscellaneous things are mixed in, and in some cases, garbage that easily ignites or garbage that becomes a direct flame is mixed in. It is also conceivable that a chemical reaction will occur in the garbage pit to ignite,
These may cause a fire in the waste pit.

Therefore, a fire extinguisher is generally installed in the dust pit. This fire extinguisher consists of a fire detection unit such as an infrared camera installed in the upper part of the garbage pit and an automatic water cannon installed on one side of the garbage pit, and the water cannon is based on the fire occurrence information from the fire detection unit. The fire extinguishing liquid is prepared to be sprayed, and aiming control is performed based on the fire position information. In this way, water is discharged toward the fire position to extinguish the fire. Further, the automatic water cannon can also be manually operated by an operation panel in a normal operation room. In this case, an operator manually aims the water while watching a television camera, for example.

[0004]

However, in the conventional fire extinguisher, since the sighting is performed by, for example, the joystick operation while watching the TV camera during the manual mote, the left and right angles in the dust pit and the water spray seen from the operator. Since the left and right angles seen from the gun are different and the left side seen from the operator may be the right side from the water cannon, it is difficult to aim aiming, especially when an unfamiliar operator operates, it is quick and suitable. Proper fire extinguishing was not easy. Further, when the operator visually operates the operation inside the garbage pit from the operation room, there is a similar problem because the operation room is separated from the water cannon.

Further, since the water cannon is provided on one side of the garbage pit, when a fire occurs just below the water cannon, the water is not sufficiently discharged. In this case, for example, a hand-type fire extinguisher is used together. There was a problem that it was not efficient because the fire had to be extinguished.

The present invention has been made under such circumstances, and an object of the present invention is to provide a fire extinguisher which can be easily controlled manually and which can efficiently extinguish a fire.

[0007]

According to a first aspect of the present invention, in a fire extinguisher for extinguishing a fire generated in a surveillance area with a water cannon, an operation room in which the surveillance area can be seen, and an operation room The water spray control and aiming control are provided in the vicinity of the operation room by manual operation of the operation panel in the operation room, and a manual water cannon installed in the same direction as the direction of the operator who operates the operation panel is provided. And

The invention of claim 2 is characterized in that, in the invention of claim 1, an automatic water spray gun is provided, which is automatically controlled and sprayed based on the detection result of the fire detecting portion.

According to a third aspect of the present invention, in the second aspect of the present invention, the manual water cannon and the automatic water cannon are arranged such that when the respective water cannons face forward, the central axes of the water cannons are orthogonal to each other. It is provided in.

According to a fourth aspect of the present invention, in a device for extinguishing a fire generated in a surveillance area having a rectangular planar shape, there are provided an automatic water cannon for automatically extinguishing a fire and a manual water cannon for manually extinguishing the fire. And a manual water cannon on the long side of the monitoring area, and an automatic water cannon on the short side.

According to a fifth aspect of the present invention, a crane for moving the deposits introduced into the monitoring area to a region on the side of the deposit processing apparatus in the monitoring area, and an area on the side of the deposit processing apparatus in the monitoring area. A water cannon provided at a position where water can be efficiently discharged.

According to the invention of claim 6, in a fire extinguisher equipped with a water cannon for extinguishing a fire in a surveillance area, a door is provided in front of the water cannon.

The invention of claim 7 is provided with a crane for moving the deposits put into the monitoring area to a region on the side of the deposit processing apparatus in the monitoring area, and a crane provided on the side of the deposit processing apparatus in the monitoring area. A first water cannon, a second water cannon that is provided so as to face the first water cannon via the monitoring area, and a front side of the first water cannon on the side of the sediment treatment device. And a door for opening and closing the opening.

[0014]

In the invention of claim 1, when the operator enters the operation room and manually controls the manual water cannon near the operation room by the operation panel, the direction of the operator and the direction of the water cannon are the same. Since the left and right angles when the operator looks at the surveillance area and the left and right angles when viewed from the water cannon are almost the same, it is easy to aim the water cannon.

According to the second aspect of the present invention, if the above-mentioned manual water cannon is further installed to the fire extinguisher equipped with an automatic water cannon that is automatically controlled based on the detection result from the fire detecting section,
Either one or both of the automatic water cannon and the manual water cannon can be selected according to the situation of the fire, and a flexible response can be taken. In this case, if a manual water cannon and an automatic water cannon are installed as in the invention of claim 3 in a monitoring area, for example, in a garbage pit, efficient fire extinguishing can be performed.

According to the fourth aspect of the present invention, since the automatic water spray gun and the manual water spray gun are provided on the sides of the monitoring area which are orthogonal to each other, efficient fire extinguishing can be performed. In addition, it is difficult to operate the manual water cannon to direct it to the fire occurrence position, but since the manual water cannon is installed on the long side, the distance to the fire occurrence position will be shorter than when it is installed on the short side, and the operation will be easier. It will be easier.

According to the fifth aspect of the present invention, since the deposits put into the monitoring area are moved in advance by the crane to the area where the water cannon is easily discharged, the dust is not suitable for the water spray of the water cannon, especially in the vicinity directly below. Because water does not collect, water can be discharged efficiently.

According to the invention of claim 6, since the door is provided in front of the water cannon, the water cannon can be shielded from the atmosphere of the monitoring area, and the water cannon is prevented from being polluted by dust or the like and corroded by corrosive gas. It can be prevented.

In the invention of claim 7, since the first and second water cannons are installed opposite to each other across the monitoring area, even if the deposits are accumulated over the entire area of the monitoring area, in any case. Even if a fire occurs, it is efficient because it can be extinguished by one or both of the water cannons. Further, since the water spray gun on the side of the sediment treatment device is provided with the door on the front surface, it is possible to prevent corrosion of the water cannon due to toxic gas generated from dust collected on the side of the sediment treatment device.

Thus, charging ports 11 and 12 for charging the dust G, which is a deposit, are formed.

On one short side of the dust pit 1, there is provided a charging hopper 13 which communicates with an incinerator 10 which is a deposit treatment device, and the dust G charged from the charging ports 11 and 12 is X. , The ceiling traveling type bucket crane 2 traveling by the Y-direction guide mechanism 21 once deposits on the right half region of the dust pit 1 in FIG. 1 and throws it into the loading hopper 13. That is, the waste G introduced into the waste pit 1 is moved to the incinerator 10 side by the crane 2, and when the amount of waste on the incinerator 10 side increases, the waste G is sequentially deposited on the left side in FIG. Usually, the waste G is contained in the right half area. Garbage like this
Is transferred (accumulated) to the incinerator 10 side, and therefore, when the waste G is transferred to the incinerator 10, the movement of the crane 2 is small and it is convenient.

Second and first automatic water cannons 3A and 3B are respectively provided on the short sides of the dust pit 1 which face each other, and one manual gate is provided on the long sides which face the inlets 11 and 12. A water cannon 4 is provided. These water cannons can be rotated horizontally and vertically, so that they can be aimed at the fire point, and spray a fire extinguisher water (not shown) to the area where the aim is made. Is.

The automatic water cannons 3A, 3B are also described below
The manual mode switching unit can be used as a manual water cannon, and the joystick can be rotated horizontally and vertically.

On the front side of the water spray gun 3B on the incinerator 10 side, an opening 32 is formed in a wall portion 31 as shown in FIGS. 1 and 3, and water is sprayed from the water spray gun 3B through this opening 32. And the opening 32
There is provided a door 33 which is manually or automatically opened and closed and which is slid horizontally, for example.

An infrared camera 5 is provided on the ceiling of the dust pit 1 so that a two-dimensional plane area in the dust pit can be scanned.
Is provided, and the temperature signal detected by the infrared camera 5 is sent to the signal processing unit 51 shown in FIG. The signal processing unit 51 determines whether or not a fire has occurred based on the temperature signal captured from the camera 5, and based on the signal from the scanning mechanism of the camera 5, the camera 5 in the plane area.
The fire position signal is output in this way. In this example, the infrared camera 5 and the signal processing unit 51 constitute a fire detection unit.

An operating room 6 is provided at the center of the long side of the garbage pit 1 where the manual water cannon 4 is installed. Inside the operating room 6, an operator faces the front of the garbage pit 1. An operation panel 61 including a valve opening / closing switch for water discharge control and joystick levers 62, 63 for aiming is provided so that the water cannon 3A (3B, 4) can be manually operated. That is, the operator's eyes are substantially parallel to the short side of the dust pit 1 when facing the operation panel 61 directly from the front.

Further, the installation of the manual water cannon 4 will be described in detail. As shown in FIG. 5, the water cannon 4 is located in the vicinity of the left side of the operation room 6, for example, at a position 2 m left from the operation room 6. The orientation of the operator who operates the operation panel 61, in other words, the orientation is the same as that of the joystick levers 62 and 63. Here, the water cannon 4 is in the same direction as the worker's direction, that is, when the worker faces directly in front of the operation panel 61, the water cannon 4 has a 90 ° direction with respect to a 180 ° horizontal turn. That is, the water cannon is installed so that it substantially corresponds to the orientation of the worker.

The fire extinguisher of this embodiment is provided with a control unit 7 as shown in FIG. 4, and this control unit 7 has a first control section 71 for manually sending a control signal to the automatic water cannons 3A, 3B and a manual control unit. A second control unit 72 for sending a control signal to the water cannon 4 and / or the water cannons 3A, 3B in the manual mode, and an automatic / manual mode switching unit 73 for switching the mode between the automatic mode and the manual mode. And have.

The first control section 71 is a water supply valve selected from one of the automatic water cannons 3A and 3B based on the fire occurrence signal sent from the fire detection section (specifically from the signal processing section 51). And an aiming control signal for determining the up, down, left and right directions of the one water cannon 3A (3B) based on the fire position information. Regarding the vertical direction of the water cannon 3A (3B), the height information of the dust at that position is arranged from the two-dimensional plane position along the height direction, for example, at a plurality of places around the side wall of the dust pit 1. It is obtained from the infrared transmissive sensor group and is determined based on this height information.

The second control section 72 is the operation panel 61.
In response to the operation signal output by the manual operation, the open signal of the water supply valve is output to the manual water cannon 4, and the aiming control signal is output.

Next, the operation of the above embodiment will be described. First, as described above, when a fire occurs in the dust pit 1, the signal processing unit 51 of the fire detection unit outputs the fire occurrence signal and the fire position signal on the two-dimensional plane to the control unit 7.
Is sent to the system monitoring room (not shown) where workers are always on standby, and the automatic mode is selected by operating the switch on the operation panel 61 or the switch on the CRT screen placed on the operation panel 61. In the meantime, the first control unit 71 issues a water discharge command (valve opening command) and aiming control to the selected one of the automatic water cannons 3A and 3B at a predetermined timing. The signal is output.

When the automatic water cannon 3B is selected, the operator opens the door 32 within a predetermined delay time after the fire signal is output and before the water cannon is started to be discharged. The door may be opened / closed by operating a switch in the operation room 6, or the door may be opened based on a fire occurrence signal. Regarding the selection of one of the automatic water cannons 3A and 3B, for example, the water cannon 3A on the left side is usually selected depending on the fire position, and the fire position is the blind spot area (of the water cannon 3A) Water cannon 3 on the right when it is inside
B will be selected. However, the automatic water cannons 3A and 3B can be simultaneously and automatically discharged by operating the operation panel 61, and in addition to the automatic water cannons 3A and 3B, the manual water cannon 4 can be used to perform manual water discharge. .

Then, when a worker rushes to the operation room 6 from the system monitoring room to grasp the situation of the fire and keeps the automatic mode at the operator's discretion, the fire from one of the selected ones, for example, the automatic water cannon 3A. Water is discharged toward the position.
When the worker selects the manual mode here, for example, one of the water cannons 3A and 3B and the water cannon 4 can be selected, and the selected two (or one) water cannons can be selected. On the other hand, aiming control is manually performed by the two (or one) joystick levers 62 (63) of the operation panel 61 to discharge water. FIG. 1 schematically shows how the water spray guns 3A and 4A are selected and water is sprayed toward the fire position.

According to the above-described embodiment, when water is discharged using the manual water cannon 4, the manual water cannon 4 is installed in the vicinity of the operation room 6 in the same direction as the direction of the operator at the time of operation. Therefore, since the left and right angles when the operator in the operation room 6 looks inside the garbage pit and the left and right angles when viewed from the water cannons 3A and 3B are almost the same, for example, a joystick operation is used to aim. It is easy to grasp the right and left operation feeling at this time, and therefore aiming is easy, and even an inexperienced operator can quickly and accurately extinguish a fire.

Since the operator can select whether to use the automatic water cannon 3A (3B) or the manual water cannon 4, it is possible to appropriately discharge water according to the condition of the unevenness of the upper surface of the dust and the like. You can take various measures. In this case, if it is possible to simultaneously perform the water discharge of the automatic water cannon 3A (3B) by the automatic control and the water discharge of the manual water cannon 4 by the manual operation, for example, when the aim of the automatic water cannon is misaligned or When a fire spreads to a place out of the position or when the momentum of the fire is very strong, the water can be discharged by the manual water cannon 4 to appropriately extinguish the fire.

Furthermore, since the automatic water cannons 3A (3B) and the manual water cannons 4 are installed on the mutually orthogonal sides, the water discharge directions cross each other, that is, when the respective water cannons face forward, Since the central axes of the water discharge are orthogonal, efficient fire extinguishing can be performed. In this case, it is advantageous to install the manual water cannon 4 near the central portion of the long side of the dust pit 1 as compared with the case of installing it on the short side. Because it is a difficult task to operate the manual water cannon 4 and direct it to the fire occurrence position,
Even if a fire occurs at the position farthest from the manual water cannon (the left and right ends of the long side facing the water cannon 4), the distance between the water cannon and the fire occurrence position is near the center on the short side. Is provided (the farthest position is the opposite short side at this time), and as a result, the operation of the manual water cannon 4 is facilitated. In such a layout, the operation room 6
If is provided on the long side, the effect becomes more remarkable as described above.

Further, since the waste in the waste pit 1 is accumulated on the side of the incinerator 10 by the crane 2, water can be efficiently discharged from the two water spray guns 3A, 4. That is, although the water cannon is not suitable for discharging water in the vicinity of its mounting position, especially in the direct downward direction because of its characteristics, the dust thrown into the dust pit 1 is sprayed beforehand by the water cannon 3A, 4 especially the water cannon 3A. Since it is moved to a place that is easy to do, in other words, almost no dust accumulates directly below the water cannons 3A, 4 so that the water can be efficiently discharged no matter where or when it is ignited. By doing so, the number of water cannons to be installed can be reduced.

Here, the amount of garbage becomes large and the garbage pit 1
Although dust may accumulate over the entire surface,
In the above-mentioned embodiment, since the two automatic water cannons 3A and 3B are arranged so as to face each other, even in such a case, water can be efficiently discharged regardless of where the dust is ignited. If the door 33 is provided in front of the water cannon 3B on the incinerator 10 side, there is an advantage that the water cannon 3B can be prevented from corroding due to toxic gas generated from dust accumulated on the incinerator 10 side. This water cannon 3B is discharged when dust is ignited in an area on the opposite side of the incinerator 10 where dust is not much accumulated, that is, an area where the water cannon 3A cannot sufficiently discharge water. Since there is not much dust accumulation in the area, even if the door is opened only when it is used, the disadvantage that the work is troublesome does not substantially occur because the frequency is low. A door may be provided on the front surface of the water cannon 3A, of course, but this is not necessary because the dust is accumulated on the incinerator side by the crane 2 as described above. The present invention is not limited to the garbage pit and can be applied to, for example, a coal silo in which coal is deposited.

[0039]

As described above, according to the present invention, there is an effect that a manual water cannon can be easily operated and a fire can be extinguished efficiently.
