Description

Technical Field

[0001] This invention relates to the technical field of intelligent fire extinguishing devices for tunnels, specifically an intelligent fire extinguishing device for tunnels based on the shielding effect of a water curtain. Background Technology

[0002] The intelligent fire extinguishing system for tunnels is a modern fire protection system that integrates automatic fire detection, intelligent analysis, rapid response and efficient fire extinguishing. It is designed specifically to deal with the complex fire risks in tunnels.

[0003] The intelligent fire extinguishing device for tunnels based on the water curtain shielding effect is an intelligent fire protection facility that uses a water curtain system to achieve fire separation and cooling protection. By forming a continuous water curtain, it blocks the spread of fire and improves the overall safety of the tunnel.

[0004] Conventional intelligent fire extinguishing devices for tunnels based on water curtain shielding often adopt an integrated fixed structure, making it difficult to flexibly increase or decrease the number of water supply mains and water curtain nozzles according to the actual segment length of the tunnel. This results in poor flexibility in adapting to tunnels of different lengths. At the same time, conventional devices cannot independently detect and control the opening and closing of fires at the corresponding locations of each water curtain unit. When a local fire occurs, the water curtains of the entire road section may be activated simultaneously, which will not only waste water resources but also affect the evacuation visibility of people in the tunnel. Summary of the Invention

[0005] The purpose of this invention is to provide a tunnel intelligent fire extinguishing device based on the water curtain shielding effect, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tunnel intelligent fire extinguishing device based on water curtain shielding, comprising a water curtain nozzle component and a combined valve component. The left and right ends of the water curtain nozzle component are connected to combined valve components, and the water curtain nozzle component and the combined valve component are alternately linked and combined. Furthermore, an L-shaped auxiliary combined component is installed at the end where the water curtain nozzle component and the combined valve component are spliced ​​together. An auxiliary fixing bracket is fitted onto the two surfaces of the water curtain nozzle component. The combined valve component includes a pressure booster valve, a docking end, a fixing seat, a signal transmission module, and a smoke sensor. The left and right ends of the pressure booster valve are integrally fixedly connected to the docking end, and fixing seats are welded and fixed to the front and rear surfaces of the pressure booster valve. A signal transmission module and a smoke sensor are respectively installed and fixed at the bottom of the pressure booster valve from top to bottom.

[0007] Furthermore, the water curtain nozzle component includes a water supply main pipe, a combination end, and a water curtain nozzle body. The combination end is integrally fixed at both ends of the water supply main pipe, and the water curtain nozzle body is vertically fixed at the lower middle part of the water supply main pipe.

[0008] Furthermore, the combined end can be sealed and connected with the docking end of the combined valve component through a threaded structure to realize the connection and expansion combination of the water supply passage between the water curtain nozzle component and the combined valve component, and the water supply main and the water curtain nozzle body are sealed and connected through a threaded structure to realize the detachable fixed connection between the two.

[0009] Furthermore, the signal transmission module is electrically connected to the smoke sensor, enabling it to transmit smoke concentration data in the tunnel to the fire control center in real time, thereby assisting dispatchers in quickly grasping the location of the fire. The mounting base has symmetrical holes for bolt installation at the end furthest from the signal transmission module and the smoke sensor.

[0010] Furthermore, the auxiliary assembly includes a main water inlet valve, a connecting end, a support base, a pressure detector, a support pipe, and a temperature sensor. The connecting end is symmetrically fixed on the surface of the main water inlet valve near the water curtain nozzle component, and the support base is welded and fixed on the front and rear sides of the main water inlet valve. A pressure detector is installed and fixed on the end of the main water inlet valve away from the connecting end, and the end of the pressure detector away from the main water inlet valve is vertically connected and fixed to the support pipe. At the same time, a temperature sensor is installed and fixed on the bottom of the main water inlet valve.

[0011] Furthermore, the temperature sensor signal output terminal is connected to the tunnel fire control host. The control host automatically controls the main water inlet valve of the corresponding area to open according to the collected fire location signal, and starts the operation of the water curtain nozzle component and the combined valve component of the corresponding area to form a continuous and sealed water curtain shielding layer. The practical use of the auxiliary combined component can realize the combination and expansion of the water curtain nozzle component and the combined valve component in the horizontal and vertical directions in conjunction with the internal structure of the tunnel. The end of the support pipe away from the pressure detector and the connecting end are sealed and connected to the combined end through a threaded structure.

[0012] Furthermore, the auxiliary fixing frame includes a lower support hoop, a stabilizing seat, a supporting crossbeam, an upper fixing hoop, and an anti-slip pad. The stabilizing seat is integrally connected to the top left and right sides of the lower support hoop, and a supporting crossbeam is integrally set horizontally in the middle of the upper end of the lower support hoop. The upper fixing hoop is correspondingly set at the bottom end of the supporting crossbeam, and the anti-slip pad is glued and fixed to the inner ring surface of both the lower support hoop and the upper fixing hoop.

[0013] Furthermore, bolt fixing holes are provided on both ends of the stabilizer, and the top two ends of the upper fixing hoop are locked to the bottom two ends of the support crossbeam. The auxiliary fixing frame can support and fix the spliced ​​water supply main pipe, and the anti-slip pad can increase the friction to prevent the water supply main pipe from sliding and shifting due to water pressure impact.

[0014] This invention provides an intelligent fire extinguishing device for tunnels based on the shielding effect of water curtain, which has the following beneficial effects: 1. The present invention, through the structural arrangement of water curtain nozzle component 1 and combined valve component 2, wherein the threaded sealing connection structure between the combined end and the docking end allows for flexible adjustment of the number of water curtain nozzle components and combined valve components installed according to the actual segment length of the tunnel, effectively improving the flexibility of the device to be adapted to tunnels of different lengths and solving the problem of poor adaptability of conventional integrated fixed structures.

[0015] 2. This invention, through the independent smoke sensor installed at the bottom of each combined valve component, in conjunction with the temperature sensor at the bottom of the auxiliary combined component, can independently detect fire at the corresponding position of each water curtain unit. After the detection signal is transmitted to the control host, only the water curtain unit in the corresponding fire area can be automatically activated, without the need for the water curtain of the entire road section to be activated at the same time. This avoids unnecessary waste of water resources and does not excessively affect the evacuation vision of personnel in the tunnel, effectively improving the intelligent fire extinguishing adaptability of the device.

[0016] 3. This invention, through the auxiliary combination components of the L-shaped structure and the threaded connection structure, can be used with the internal corner structure of the tunnel to complete the horizontal and vertical expansion installation of the device, further improving the adaptability of the device to different internal tunnel structures. At the same time, the lower support hoop of the auxiliary fixing frame, together with the upper fixing hoop, can stably support the spliced ​​water supply main pipe, and the anti-slip pad of the inner ring can effectively prevent the water supply main pipe from shifting due to water pressure impact, thus improving the overall structural stability of the device after installation.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] like Figures 1 to 5As shown, a tunnel intelligent fire extinguishing device based on water curtain shielding includes a water curtain nozzle component 1 and a combination valve component 2. The left and right ends of the water curtain nozzle component 1 are connected to the combination valve component 2, and the water curtain nozzle component 1 and the combination valve component 2 are alternately linked and combined. An L-shaped auxiliary combination component 3 is installed at the end where the water curtain nozzle component 1 and the combination valve component 2 are assembled. An auxiliary fixing bracket 4 is sleeved on both sides of the water curtain nozzle component 1. The combination valve component 2 includes a pressure boosting valve 201 and a docking end 2. 02. The pressure booster valve 201 is integrally fixedly connected to the left and right ends with docking ends 202, and the pressure booster valve 201 is welded and fixedly fixed to the front and rear side surfaces with the fixing base 203. Moreover, the pressure booster valve 201 is fixedly installed and fixedly mounted from top to bottom with the signal transmission module 204 and the smoke sensor 205. The water curtain nozzle component 1 includes a water supply main pipe 101, a combination end 102 and a water curtain nozzle body 103. The left and right ends of the water supply main pipe 101 are integrally fixed with the combination end 202. The water curtain nozzle body 103 is vertically fixedly installed at the lower middle part of the main water supply pipe 101 and the combined end 102. The combined end 102 can be sealed with the docking end 202 of the combined valve component 2 through a threaded structure to realize the connection and expansion combination of the water supply passage between the water curtain nozzle component 1 and the combined valve component 2. The main water supply pipe 101 and the water curtain nozzle body 103 are sealed with a threaded structure to realize the detachable fixed connection between the two. The signal transmission module 204 is electrically connected to the smoke sensor 205, which can transmit the smoke concentration data in the tunnel to the fire control center in real time to assist dispatchers in quickly grasping the fire location. The fixed seat 203 has symmetrical holes for bolt installation on the left and right sides of the end away from the signal transmission module 204 and the smoke sensor 205. In use, the threaded sealing docking structure between the combined end 102 and the docking end 202 can be used to flexibly increase or decrease the number of water curtain nozzle components 1 and combined valve components 2 according to the actual segment length of the tunnel, effectively improving the flexibility of the device to be used in tunnels of different lengths.

[0021] The auxiliary assembly 3 includes a main water inlet valve 301, a connecting end 302, a support base 303, a pressure detector 304, a support pipe 305, and a temperature sensor 306. The connecting end 302 is symmetrically fixed to the surface of the main water inlet valve 301 near the water curtain nozzle assembly 1. Support bases 303 are welded and fixed to both the front and rear sides of the main water inlet valve 301. A pressure detector 304 is installed and fixed to the end of the main water inlet valve 301 away from the connecting end 302, and the end of the pressure detector 304 away from the main water inlet valve 301 is vertically connected to and fixed to the support pipe 305. A temperature sensor 306 is installed and fixed to the bottom of the main water inlet valve 301. The signal output of the temperature sensor 306 is connected to the tunnel fire control host. Based on the collected fire location signal, the control host automatically controls the opening of the main water inlet valve 301 in the corresponding area, activating the water curtain nozzle assembly 1 and the combined assembly in the corresponding area. Valve component 2 operates to form a continuous, sealed water curtain shielding layer. The auxiliary assembly component 3 enables the water curtain nozzle component 1 and the combined valve component 2 to be combined and expanded horizontally and vertically in accordance with the tunnel's internal structure. The end of the support pipe 305 furthest from the pressure detector 304 and the connecting end 302 are sealed to the combined end 102 via a threaded structure. During use, the smoke sensor 205 independently installed at the bottom of each combined valve component 2, in conjunction with the temperature sensor 306 at the bottom of the auxiliary assembly component 3, can independently detect fires at corresponding locations of each water curtain unit. After the detection signal is transmitted to the control host, only the water curtain unit in the corresponding fire area can be automatically activated, eliminating the need for simultaneous activation of the entire road section's water curtain. This avoids unnecessary water waste and does not excessively obstruct the evacuation visibility of personnel within the tunnel, thus improving the device's intelligent fire suppression adaptability. The L-shaped auxiliary assembly component 3, with its threaded connection structure, can also be used with the tunnel's internal corner structures to complete the horizontal and vertical expansion of the device, further enhancing its adaptability to different tunnel internal structures.

[0022] The auxiliary fixing frame 4 includes a lower support hoop 401, a stable seat 402, a support crossbeam 403, an upper fixing hoop 404, and an anti-slip pad 405. The stable seat 402 is integrally connected to the top left and right sides of the lower support hoop 401, and the support crossbeam 403 is integrally and horizontally installed at the middle of the upper end of the lower support hoop 401. The upper fixing hoop 404 is correspondingly installed at the bottom end of the support crossbeam 403. Anti-slip pads 405 are adhered and fixed to the inner surfaces of both the lower support hoop 401 and the upper fixing hoop 404. Bolt fixing holes are opened on both ends of the stable seat 402. The upper fixing hoop 404... The top two ends of the 04 are locked to the bottom of the support crossbeam 403. The auxiliary fixing frame 4 can support and fix the spliced ​​water supply main pipe 101. The anti-slip pad 405 can increase the friction to prevent the water supply main pipe 101 from sliding and shifting due to water pressure impact. In use, the lower support hoop 401 and the upper fixing hoop 404 are used to stably support the spliced ​​water supply main pipe 101. With the anti-slip pad 405 on the inner ring, the water supply main pipe 101 can be effectively prevented from shifting due to water pressure impact, which further improves the structural stability of the device after installation.

[0023] In summary, as Figures 1 to 5 As shown, this intelligent fire extinguishing device for tunnels based on water curtain shielding is used by first adjusting the number of water curtain nozzle components 1 and combined valve components 2 according to the design length and internal structure of the tunnel through the threaded sealing connection structure between the combined end 102 and the docking end 202. When encountering a tunnel corner structure, it is used in conjunction with the auxiliary combined component 3 of the L-shaped structure to complete the horizontal and vertical expansion connection of the device through threaded connection. Finally, the lower support hoop 401 of the auxiliary fixing frame 4 is used in conjunction with the upper fixing hoop 404 and the supporting cross frame 403 to lock and support the assembled water supply main pipe 101. The stabilizing seat 402 is fixed to the inner wall of the tunnel by bolts, completing the overall installation and fixing of the device. During normal operation, the smoke sensor 205 at the bottom of each combined valve component 2 and the temperature sensor 306 at the bottom of the auxiliary combined component 3 continuously monitor the corresponding area in real time. When a fire occurs in the corresponding area, the smoke concentration and ambient temperature trigger the sensors, and the detection signal is sent to the tunnel fire control host through the signal transmission module 204. The control host automatically opens the main water inlet valve 301 of the corresponding area according to the fire location signal, and the booster valve 201 starts simultaneously. The pressurized water is sprayed out from the water curtain nozzle body 103 through the water supply main pipe 101, quickly forming a continuous and sealed water curtain shielding layer to block the spread of fire and the diffusion of heat radiation. The control host also transmits the fire location information to the fire control center at the same time to assist dispatchers in quickly carrying out fire fighting and evacuation work. During the fire fighting process, the pressure detector 304 can monitor the water inlet pressure of the device in real time to ensure the formation effect of the water curtain. The above is the entire usage process of the device. The present invention has a flexible and adaptable structure, intelligent detection and zone activation, and a stable overall structure, which can better meet the needs of tunnel fire fighting.
