Description

Technical Field

[0001] The present invention relates to the technical field of highway tunnel fire protection, and in particular to an intelligent fire extinguishing system for a tunnel. Background Art

[0002] In my country's highway tunnels, most of the existing tunnel fire extinguishing systems use water as the main medium for fire extinguishing. This practice is relatively backward and manifested in the following aspects: ① Firefighters take too long to arrive at the scene and miss the best time for fire extinguishing; ② The use of water or ordinary fire extinguishing methods has poor fire extinguishing efficiency, the fire extinguishing types are very limited, and are prone to secondary hazards; ③ There are great hidden dangers of on-site fire extinguishing; ④ The level of intelligence is low, and fire extinguishing cannot be carried out safely, quickly and efficiently; ⑤ There is no water or insufficient water around many tunnels, which makes fire extinguishing even worse.

[0003] The existing technology lacks systematicity and scientificity in terms of substantial fire extinguishing. Therefore, it is necessary to invent an intelligent tunnel fire extinguishing system to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent fire extinguishing system for a tunnel.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A tunnel intelligent fire-fighting system, the tunnel is divided into a plurality of protection zones, a plurality of flame detectors are arranged in the protection zones, and each protection zone is provided with an address module; a plurality of suspended ultrafine dry powder fire-extinguishing devices are evenly arranged on both sides of the protection zones; a plurality of manual alarm buttons, a plurality of sound and light alarms, a plurality of intelligent fire alarm hosts, a plurality of switches, and a plurality of fire-fighting power supplies are also arranged; a driving induction device and an interception device are arranged at the entrance of the tunnel; a central control room alarm host and a hard disk recorder are arranged in the fire-fighting monitoring room; the central control room alarm host is installed with intelligent fire-fighting software.

[0006] Specifically, the intelligent fire extinguishing software displays in real time the address information of each protection zone, the status of the flame detector, the status of the alarm button, the spraying status of the dry powder fire extinguishing device, the alarm reset, settings, and the manual remote start window.

[0007] Specifically, the flame detector is a three-band red and ultraviolet composite flame detector.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] like Figure 1 As shown, an intelligent fire-fighting system for a tunnel is provided. The tunnel is divided into several protection zones. Several flame detectors are arranged in the protection zones, and each protection zone is provided with an address module. Several suspended ultra-fine dry powder fire-extinguishing devices are evenly arranged on both sides of the protection zones, and several manual alarm buttons are evenly arranged on both sides of the protection zones. Several sound and light alarms, several intelligent fire alarm hosts, several switches, and several fire power supplies are also provided to supply power to the electric fire-fighting equipment in the tunnel. A driving induction device and an interception device are provided at the entrance of the tunnel. A hard disk recorder and a central control room alarm host are provided in the fire-fighting monitoring room; and the intelligent fire-fighting software is installed in the central control room alarm host.

[0017] Specifically, the intelligent fire-fighting extinguishing software displays in real time the address information of each protection zone, the status of the flame detector, the status of the alarm button, the spraying status of the dry powder fire extinguishing device, the alarm reset, settings and the manual remote start window. When a fire signal or a manual alarm signal is received from the on-site flame detector, the intelligent fire alarm host automatically controls the sound and light alarm to send out a sound and light alarm. The alarm host in the central control room of the fire-fighting monitoring room automatically sends out a sound alarm and displays the address information of the alarmed protection zone, reminding the management personnel to check and handle it. After confirming the fire through video methods, first evacuate the personnel in the fire area in the tunnel, and then remotely or locally start the ultra-fine dry powder for automatic spraying of fire extinguishing protection.

[0018] Specifically, the flame detector is a three-band red and ultraviolet composite flame detector.

[0019] Specifically, the central control room alarm host and the intelligent fire alarm host communicate signals via optical fiber.

[0020] The working principle of this application is: When a fire occurs in a highway tunnel, the flame detector detects the fire in real time, and the address module of the protection zone where the fire occurs sends the flame event and the location of the protection zone where the fire occurs to the intelligent fire alarm host, and activates the sound and light alarm and voice alarm functions; the intelligent fire alarm host also uploads the received signal to the alarm host in the central control room of the fire extinguishing monitoring room. After the intelligent fire extinguishing software receives the signal, it activates the sound alarm function, video capture, pop-up window, focus function, and hard disk recorder function. After the management personnel confirm the occurrence of the fire through video methods, they evacuate the crowd in the highway tunnel through video intercom and shouting. After confirming that the people have evacuated to a safe distance, they start the linkage control between the intelligent fire alarm host or the alarm host in the central control room of the fire extinguishing monitoring room and the fire extinguishing equipment; there are two ways to start: (1) When the on-site manager hears the fire alarm or sees a fire, he / she will first evacuate the personnel on the scene and make sure that they are away from the fire area. Then, he / she will go to the intelligent fire alarm host of the corresponding alarm protection area, manually enter the correct start password, and start the ultra-fine dry powder fire extinguishing device in the protection area and adjacent protection areas to automatically spray and extinguish the fire; (2) After the alarm host in the control room of the fire extinguishing monitoring room receives the fire information, the management personnel will check the fire address information. After confirming the fire situation through video, they will first remind the on-site personnel to evacuate through video intercom and broadcasting. After confirming that the personnel are away from the fire area, they will click on the start interface and enter the correct password to start the ultra-fine dry powder fire extinguishing device for automatic spraying and fire extinguishing.

[0021] When a fire is confirmed in the tunnel, the tunnel management personnel can activate the driving induction device and the automatic interception device through the intelligent fire alarm host or the alarm host in the central control room of the fire extinguishing monitoring room.

[0022] The fire extinguishing powder floats in the air for a period of time to confirm that there is no possibility of the fire re-igniting. The floating fire extinguishing powder in the tunnel is quickly discharged through the intelligent fire alarm host or the central control room alarm host and the original fan in the tunnel.

[0023] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0024] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
