Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fire extinguishing system using a fire extinguishing agent discharge nozzle called a turret nozzle, monitor nozzle or water cannon.

Conventional fire extinguishing equipment of this type uses a turret nozzle, monitor nozzle, or water cannon, which can freely rotate horizontally, vertically, and other extinguishing agent discharge nozzles, to target objects to be extinguished, such as plant equipment, tank bases, sea berths, buildings, and tunnels. In the event of a fire, the extinguishing agent discharge nozzle can be manually rotated directly, or remotely rotated using a control stick from a position where the discharge nozzle and the object to be extinguished can be visually confirmed, and the nozzle aiming at the fire point. fire extinguishing agents such as powder, foam or water.

However, with this kind of fire extinguishing system, the extinguishing agent discharge nozzle must be operated near the fire point, whether it is operated manually or remotely using a control stick, and the operator is always at risk of fire or explosion. was exposed to.

In addition, when remotely controlling the extinguishing agent discharge nozzle using a control stick, the distance between the operator and the nozzle makes it difficult to aim the nozzle at the fire point, which takes time. It has a major drawback that it takes time to reach the discharge nozzle or its operating rod, making it impossible to extinguish the fire in its initial stage.

In view of the above points, this invention provides a television camera that monitors the object to be extinguished while rotating horizontally and vertically near the object to be extinguished, and a fire extinguishing agent discharge nozzle that rotates in synchronization with the television camera. By monitoring images from television cameras using a receiver installed at a central control center, etc., and stopping the rotation of the television camera when the image of the fire spot appears on the receiver,
The present invention provides a fire extinguishing system in which a fire extinguishing agent discharge nozzle automatically aims discharge at a fire location.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a television camera installed in the vicinity of objects to be extinguished (not shown) such as plant equipment, tanks, sea berths, tunnels, and buildings, and 11 a camera that rotates the television camera 1 horizontally, vertically, and vertically to monitor objects to be extinguished. Rotating device, 2,3
2 is a turret nozzle, monitor nozzle, or water cannon or other extinguishing agent discharge nozzle installed near the object to be extinguished.
0 and 3 synchronize the discharge nozzles 2 and 3 with the camera 1 so that the discharge aim of the discharge nozzles 2 and 3 always matches the shooting aim of the television camera 1 by the rotation control signal output from the camera rotation device 11. A nozzle rotating device 4 is a fire extinguishing agent supply source that supplies a fire extinguishing agent such as powder, foam or water to the extinguishing agent discharge nozzles 2 and 3.

Reference numeral 5 denotes a control device installed in a disaster prevention terminal 6 such as a central management center, 51 a receiver for the television camera 1, 52 a rotation control unit that controls the rotation device 11 of the television camera 1, and 53 a fire extinguishing agent supply. a release control section that controls the source 4; 54 is a control section 52;
．． This is an operation panel provided with 53 operation switches and the like.

Reference numeral 7 denotes a fire receiver that receives a fire signal from a fire detector, manual notification device, or the like (not shown) provided along the object to be extinguished.

Next, the operation of this fire extinguishing system will be explained.

When the fire receiver 7 receives a fire signal from a fire detector or manual notification device, and an emergency bell etc. is used to notify that a fire has broken out in the object to be extinguished, or an emergency telephone etc. is notified that a fire has occurred. Then, the image receiving switch and rotation control switch (not shown) provided on the operation panel 54 are turned on.

When both switches are turned on, the television camera 1 starts photographing the object to be extinguished and sends the image to the receiver 51. At the same time, the rotation control unit 52 outputs a rotation signal, and this rotation signal causes the rotation device to 1. The television camera 1 is rotated left, right, up and down so that the television camera 1 sequentially transmits images of each part of the object to be extinguished.

The rotation device 11 also transmits a rotation control signal to the nozzle rotation device 21.
and 3, and this rotation control signal causes the rotation device 21 to
and 31 rotate the extinguishing agent discharge nozzles 2 and 3 in synchronization with the camera 1 so that their discharge aiming points coincide with the photographing aiming point of the television camera 1.

When the image from the rotating television camera 1 is monitored by the receiver 51, and the image of the fire spot is received in the center of the screen of the receiver 51, and it is confirmed that the camera 1 has captured the fire spot with the shooting sight, The rotation control switch on the operation panel 54 is turned off to stop the rotation signal output from the rotation control section 52.

By stopping the output of the rotation signal, the rotation device 11 stops rotating the television camera 1 and stops outputting the rotation control signal, so that the rotation devices 21 and 31 control the fire extinguishing agent discharge nozzles 2 and 3.
stop rotating.

By stopping the rotation of the rotation devices 1, 21, and 3, the photographing sight of the television camera 1 and the discharge sight of the fire extinguishing agent discharge nozzles 2 and 3 are both fixed in a state facing the fire spot.

When the discharge switch on the operation panel 54 is turned on, a control signal is output from the discharge control unit 53 to the extinguishing agent supply source 4, and the extinguishing agent supply source 4 is activated by this control signal to pressurize the extinguishing agent and discharge the extinguishing agent. The extinguishing agent is supplied to nozzles 2 and 3, and the discharge nozzles 2 and 3 discharge the supplied extinguishing agent to the fire location.

By the way, in the above embodiment, the television camera 1 and the extinguishing agent discharge nozzles 2 and 3 are automatically rotated by a rotation signal, but a rotation operation lever is provided on the operation panel 54, and this rotation operation lever can be operated. The TV camera 1 and the fire extinguishing agent discharge nozzle 2' output a rotation signal such as a pulse signal indicating the rotation direction.

3 may be controlled to rotate in any direction.

In addition, if there is a risk that the extinguishing agent discharged from the extinguishing agent discharge nozzles 2 and 3 may be deflected by the wind, a measuring device for measuring the wind direction and wind speed and a calculation device that calculates the degree of deflection from the measured values of this measuring device A deflection measuring section consisting of the following may be provided, and the discharge aim of the extinguishing agent discharging nozzle may be corrected automatically or by an operation panel based on the measurement results of the deflection measuring section.

Furthermore, by using a nozzle that swings around a discharge aim depending on the pressure of the extinguishing agent supplied to the extinguishing agent discharge nozzles 2 and 3, the extinguishing agent can be sprayed around the fire location as well.

In addition, in the above explanation, an example in which a television camera and a fire extinguishing agent discharge nozzle are installed separately has been described.
A television camera is fixed to a fire extinguishing agent discharge nozzle so that the photographing aim of the camera and the discharge sight of the nozzle match, and the television camera and the fire extinguishing agent discharge nozzle are rotated together by one rotating device. You can also do that.

According to this invention, a television camera whose rotation is controlled to capture a fire spot near an object to be extinguished and a fire extinguishing agent discharging nozzle whose rotation is controlled to discharge extinguishing agent to the fire spot are connected to each other. The sight is set so that it rotates in line with the nozzle emission sight, and the camera stops rotating when it is confirmed that the image of the TV camera is monitored by the receiver and that the camera has captured the fire point with the shooting sight. As a result, the discharge aim of the extinguishing agent discharge nozzle is automatically determined at the fire point, so that extinguishing agent can be safely and reliably discharged to the fire point without being exposed to the risk of fire explosion at the initial stage of a fire. Thus, a fire extinguishing device capable of quickly extinguishing a fire can be obtained.
