Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building fire unmanned fire extinguishing system and apparatus, and particularly to extinguishing fire without a person entering the fire site in high-rise areas where fire trucks cannot reach a ladder or in underground passages and underground malls where fire trucks cannot enter. The present invention relates to a system and a device that can be used.

[0002]

2. Description of the Related Art Conventionally, some high-rise buildings have sprinkler facilities. In addition, there are cases where a fire ladder car is used to extinguish a fire from the outside in case of a fire. Furthermore, hoses and pipes are installed on the upper floor, or firefighters carry them up,
There are also cases where fire fighting activities are performed by obtaining water from the internal water supply pipes or fire engines downstairs.

[0003]

In the case of the above-mentioned sprinkler, it is effective for extinguishing the fire at the initial stage of firing and within the range of the water discharge, but when the fire is strong, it is remarkably effective against the fire outside the water discharge range. Be reduced. Especially in the case of fire spread from downstairs, the fire is strong, and the water pressure is low in the upper part, so it is useless. In addition, the fire ladder car is the highest around 50m above the ground, and the number of building floors reaches only about 15th to 17th floors, so it is useless for more floors. On the other hand, even when a firefighter extinguishes a fire at a fire site, it is dangerous to move forward if there is a lot of smoke, and the fire force goes to the upper layers, so even if fire fighting at the fire site is possible. , It is dangerous to place firefighters on the upper floor, and if the fire spreads to the upper floor of the fire base, it is virtually difficult to extinguish the fire on the upper floor. This is the 20th floor,
In case of fire in the high-rise area such as 40th floor, water pressure, difficulty of hose deployment, malfunction of communication with ground command department (disconnection of radio,
(Interference) etc., and many difficult problems occur in work. In addition, it is difficult to extinguish a fire in an underground mall because fire smoke is concentrated at the entrance. In view of the above situation, the present invention can automatically and unattended water discharge suitable for the fire on the fire site, the upper floor and the lower floor at the same time as the fire, and in any high-rise building or maze. It was developed for the purpose of providing an unmanned fire extinguishing system and a building fire that can extinguish a fire accurately by a remote control even in such an underground mall.

[0004]

The present invention has taken the following technical means in order to solve the above problems and achieve the objects.

First, in the case of a high-rise building, a water pipe communicating from the basement to the uppermost floor is arranged, and in an underground mall, etc., a water pipe is arranged vertically from the vicinity of the entrance of the above-ground part to the basement, and the horizontal direction is provided on each floor. A water pipe was installed. Next, in the case of a high-rise building, an automatic water discharger was installed on the water pipe on each floor, and a fire detector was installed near it. In the underground mall, an automatic water discharge part and a fire detector were installed at each required part. On the other hand, in the basement, the water supply pipe was equipped with a water supply unit and a control device. The control device is electrically connected to the automatic water discharger, the fire detector, and the water supply unit, and has a function of supplying water from the water supply unit based on the data detected by the fire detector such as smoke and heat. It consists of a fire-extinguishing system that has the function of automatically discharging water from the water discharge part in the flame direction and the function of controlling related parts by human input, and the devices that compose it.

The water supply unit has a pump, and the pump power is controlled by the control device. The water discharge part has an automatic valve, and the automatic valve is controlled by a controller. The fire detector has a smoke sensor, a heat sensor, and if necessary, a sound sensor and an optical sensor, and the detection data is analyzed by the control device, and the control device determines the control of each part according to the analyzed value. To do.

[0007]

The present invention constructed as described above has the following actions. For example, when there is a fire on the 25th floor at night, the fire detector detects the occurrence of the fire and sends the data to the control device. The control device issues an alarm when the standard is reached based on the data (heat, smoke concentration). In this case, if automatic water discharge is set, the control device
The automatic valve of the water discharge section on the floor will be opened, and the pump of the water supply section will be operated to automatically discharge water. When "automatic water discharge" is not set, the fire engine arrives, but when it is confirmed by the data of the fire detector that the fireman cannot go to the fire site, the manual button operation of the control device Water is discharged by operating the pump and opening the automatic valve in the water discharge section at the required location on the required floor. When it is predicted that the fire spreads from the 25th floor to the 26th floor, by opening the automatic valves at the necessary locations (for example, stairs, elevators, corridors, etc.) on the 26th and 27th floors,
Unmanned water discharge is started on the upper floors where it is difficult for firefighters to climb.

[0008]

Embodiments of the present invention will be described with reference to the drawings. Fig. 1 shows the case of implementation in a high-rise building. In the present invention, the "building" is a building, and includes underground structures such as factories, underpasses, underground shopping streets, underground parking lots, tunnels, and underground storages. In FIG. 1, a water pipe 2 is attached to the wall so that the basement 1A and the highest floor 1B of the high-rise building 1 communicate with each other.
Is provided. On the first floor, the water supply pipe 2 has a water supply unit 3
Is provided. The water supply unit 3 has a power pump (not shown) inside, and the intake port of the pump is the water tank 4, the water supply 5,
Alternatively, it can be connected to the water outlet of the fire engine 6. Branch pipes 2A ... Are arranged in the water supply pipe 2 on each floor, and the branch pipes 2A are arbitrarily branched for each floor.
That is, in FIG. 1, the branch pipes 2A are arranged in four lateral corners of the room in a rectangular shape and the branch pipes 2B, 2B are moved upward from a desired position.
... is made to rise, and a water discharge part 7, 7 is provided at the base thereof, an automatic valve (manual combined use) is arranged, and the branch pipe 2B is raised.
Are provided with a plurality of nozzles 2C. When it is not in the room, the branch pipes 2B are made to stand up on the side of the corridor and stairs as shown in FIG. 2 is assumed to be the plane of the high-rise part of the hotel, and branch pipes 2B ... Are arranged at important points in the corridor as shown in FIG. Further, the nozzles 2C are arranged obliquely upward, and when water is discharged, a water curtain is stretched as shown in FIG. 3, and even if a flame crawls the ceiling portion, it is extinguished to prevent spread of fire. For example, in FIG. 2, when a fire breaks out from room 2201, if there is water discharge in the area 2202, the spread of fire toward the room 2203 can be stopped. If the discovery is delayed, or if a fire breaks out from room 2204, the discharge of flames to the upper floors of the 2204 and stairs blocks the outflow of flames, that is, the spread of fire from the fire floor to the upper floors. . In order to complete this completely, fire detectors 8 ... Are arranged in each room and corridor key points. The fire detectors 8 and the electric wires 9 extending from the water discharge parts 7 are electrically connected to a control device 10 arranged near the water supply part 3.
In the case where the water discharger 7 has a nozzle directly or through the branch pipe 2B, a multi-head nozzle or a variable direction nozzle can be used according to the setting place, and a driving machine that changes the direction of the nozzle is provided. The drive unit to the controller 1
It is controlled by 0. The fire detector 8 includes any of a smoke sensor (gas concentration detection), a heat sensor (temperature sensor), a pressure sensor (atmospheric pressure sensor), and a sound sensor (presence or absence of a person, combustion sound, water discharge sound detection). Can be combined. The controller 10 has both automatic control and human input control functions. As a system, first, the input data (gas concentration, temperature, atmospheric pressure, sound wave) from the fire detector 8 is analyzed, and an alarm is issued with a constant reference value.
The alarm can be issued by sound or light alone or in combination, and the alarm can be stopped by a switch input at the site or the control device 10 side by the site confirmation by a person or a guard who notices this. Regarding the water discharge control, a function of switching between automatic and human input is provided, and when it is left unattended at night or for a certain period of time, it can be switched to automatic control. In the case of human control, for the data input from the fire detector 8 to the control device 10, there is a transmission prompting water discharge when water discharge is required. In that case, for example, the automatic water discharge section 7 of which floor and number is used. It is displayed whether water is required. It is convenient to turn on the display on the panel. Therefore, in FIG. 2, when a fire broke out of room 2201, the guards 2201
When it is determined that water has to be discharged to the room No. 2, when the input switch of the water discharge section is turned on at the site, the control device 10 outputs a signal to operate the pump of the water supply section 3 and the automatic valve of the 2201 automatic water discharge section 7 Is opened, that is, water is discharged from the 2201 automatic water discharge part. When the fire is extinguished, the fire detector sends data such as the room temperature and the presence of smoke to the control device 10. Therefore, if the control device 10 determines that the fire has been extinguished, the pump operation is automatically stopped and the automatic valve is activated. Close. In this case, in the case of a hotel, the monitoring panel of the control device 10 is installed in the front desk or the guard room. 2201
When the room is on the 22nd floor, it is difficult to send water by the pump pressure. Therefore, as shown in FIG. 1, the water pump 2 is provided with a pressurizing pump 11 at each height of the water pressure limit. The operation of the control device 10 is automatically controlled by the floor from which the signal from the fire detector 8 is sent. If there is a part where the fire detector 8 does not operate due to an explosion accident or the like near the room 2204 and data requiring water discharge is sent from the other detectors 8, the control device 1
When 0 is input manually, the automatic valve of the automatic water discharger 7 is opened to prevent the spread of fire on the 22nd floor, and if there is a risk of spread to the upper floor, the stairs on the upper floor,
By controlling the first floor without discharging water to the elevator, smoke rises to the 22nd and higher floors, preventing fire spread to the upper floors even if firefighters cannot go to the upper floors. To be That is, the fire smoke rises up the stairs and the elevator part like a smoke tube, but since the water curtain extinguishes the flame, only the smoke rises and the spread of fire is stopped.
The automatic valve of the automatic water discharge part 7 can freely control the degree of opening and closing.
The amount of water discharged can be controlled by controlling this. If the control device 10 is switched to automatic water discharge, even in an unmanned building, water will be automatically discharged from the automatic water discharge part 7 on site in the event of a fire. There are various problems in extinguishing a fire inside a room. That is, it is soaked by water discharge and the front surface of the nozzle is shielded by arranging the article, so that the water discharge effect cannot be obtained. However, if the nozzles are arranged near the ceiling, the water discharge efficiency will decrease. Therefore, considering the purpose of extinguishing fires, there are two points: first, to secure the exit to protect the safety of the life of people inside, and second, to prevent the spread of fire to adjacent parts. The purpose is achieved by giving priority to water discharge. In this case, a water curtain type and a multi-head nozzle as shown in FIG. 3 are preferable.

When a fire occurs in the underground mall, smoke flows to the entrance to the ground, which makes it difficult for firefighters to enter from the ground, making it difficult to extinguish fire. In particular, when a fire occurs in an underground construction in which a subway station, an underground shopping area and an underground sales floor of a department are connected, fire spreading is spread in many directions, making it difficult to extinguish the fire. Therefore, even in an underground shopping mall or the like, as shown in FIG. 2, it is possible to prevent the spread of fire by arranging the automatic water discharge parts 7 ... In order to block the flame by stretching a water curtain at a key part of the passage. . Inside the store, the automatic water discharger 7 and the detector 8 can be appropriately arranged according to the respective requirements.

Buildings differ greatly depending on the place where they are built and their purpose. That is, when roughly classified by the presence or absence of the underground water tank, when the water tank 4 is provided, the water supply section 3 can automatically extinguish the fire by connecting the intake port of the power pump to the water tank 4. Even without a water tank,
When the fire faucet 5 is in the vicinity, automatic fire extinguishing is possible by connecting the connecting pipe to the water supply unit 3. When the fire hydrant is located far away, after the fire is detected, the connecting hose is connected between the hydrant 5 and the water supply unit 3 and then the control device 10 is manually operated to input to the pump, and Open the automatic valve of the automatic water discharger 7 at the fire site.

In the multi-head nozzle, it is possible to efficiently extinguish a fire by horizontally rotating and swinging the head. In that case, a fire detector can be separately incorporated into the multi-head nozzle itself. That is, for example, the infrared sensor can detect heat, and the controller can control the driving machine so that the nozzle faces the direction in which the heat is highest. This mechanism is also effective in unmanned warehouses, tunnels, etc.

[0012]

As described above, the present invention has the following excellent effects.

A. An automatic water discharge part is arranged in a branch pipe branched from the water supply pipe, a fire detector is arranged in the vicinity of the automatic water discharge part, and when a fire is detected by the fire detector,
Since the data has a display mechanism and an automatic control mechanism that can be confirmed by the control device on the first floor (upper floor if the control room is on the upper floor), if you set it automatically, the fire scene will be unattended. You can extinguish the fire.

B. Even if you set the control device to human control, you can check the situation of the site by looking at the display of the control device without going to the fire scene, and switch on the part that requires water discharge to switch the automatic water discharge part. The automatic valve can be opened to extinguish a fire unattended even in a situation where no one can enter.

C. Since the water pipe can be attached to the outer wall of the building, it can be easily implemented in existing buildings.

D. It is often difficult to enter the underground shopping area such as a maze from the ground at the time of a fire.In addition, there is a lot of trouble in the fire extinguishing activity due to the loss of sense of direction inside, but it is possible to check the fire scene and the situation by the control device, so it is appropriate. It is possible to extinguish the fire efficiently by remotely operating the automatic water discharge part at the fire site.

E. Even in a fire scene where it is difficult for people to enter due to the strong force of smoke, only one person who can operate the control device can extinguish the fire.
