Description

Technical Field

[0001] This invention relates to the field of tunnel fire safety technology, and in particular to an intelligent control system and method for fire-fighting and antifreeze water supply in highway tunnels in cold regions. Background Technology

[0002] With rapid social and economic development, human demand for infrastructure construction and improvement is gradually increasing. Highway construction is a crucial component of modern transportation, and its function extends beyond simply meeting people's travel needs; it now emphasizes passenger safety and the transport of essential goods. However, in the cold winter, highway environments, especially highway tunnels, often face extreme weather and severe climatic conditions, posing higher requirements and challenges to the normal use and management of highway infrastructure.

[0003] To address the issues of freezing and fire prevention in highway tunnels during cold seasons, highway fire-fighting water supply systems have been implemented in the initial construction phase. In practice, traditional highway tunnel fire-fighting water supply systems typically rely on manual monitoring, routine inspections, and manual switching. This method is inefficient, lacks intelligent control mechanisms, and suffers from issues such as missed monitoring, missed inspections, and leaks in pipelines, making it difficult to guarantee freezing prevention effectiveness. Furthermore, in the event of a sudden fire, traditional fire-fighting water supply facilities may be unable to respond quickly due to limitations imposed by climate, time, and space, leading to the escalation and uncontrollability of the incident. Summary of the Invention

[0004] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an intelligent control system and method for fire protection and antifreeze water supply in cold-region highway tunnels, so as to solve the existing problems.

[0006] To achieve the above objectives, the technical solution of the present invention is: an intelligent control system for fire-fighting and antifreeze water supply in highway tunnels in cold regions, comprising a deep well, a fire water tank, a temperature sensor, a level sensor, a flow meter, an intelligent controller, connecting pipes, and sensors. The deep well is equipped with a deep water pump, and the fire water tank is equipped with a water-cooled wall. The fire water tank is connected to the deep water pump and has a water pump. The temperature sensor and the level sensor are respectively located in the deep well and the fire water tank. The flow meter is located at the outlet of the deep well and the fire water tank. The intelligent controller connects and controls each of the deep water pump, the water-cooled wall, the water pump, the temperature sensor, the level sensor, and the flow meter. The connecting pipes are located on both sides of the tunnel, connected to the water pumps, and connected to the fire water tank for circulation. The connecting pipes are equipped with multiple electric valves and multiple spiral blades inside the pipes. The sensors are located on the connecting pipes.

[0007] In some embodiments, the intelligent controller includes a recording module, an alarm module, and a transmission module.

[0008] In some embodiments, the temperature sensor, the level sensor, and the flow meter are all equipped with a wireless module and a positioning module.

[0009] In some embodiments, the surface of the helical blade is provided with a drive groove.

[0010] In some embodiments, the sensor is ring-shaped and has multiple sensing strips that are in close contact with the outer wall of the connecting pipe.

[0011] In some embodiments, the flow meter is also installed at the connection of the connecting pipe, and the inner wall of the flow meter is provided with a groove, in which a pressure sensing module is provided and a sensing ball is provided, which is connected to the groove by a spring.

[0012] This invention also provides an intelligent control method for antifreeze water supply in a fire-fighting and antifreeze water supply intelligent control system for highway tunnels in cold regions. When the temperature reaches a critical value, the temperature data transmitted by the temperature sensor is fed back to the intelligent controller. Then, the intelligent controller controls the deep water pump to pump water into the fire water tank, activates the water-cooled wall to heat the water in the fire water tank, and then pumps it out to the connecting pipe for de-icing. At the same time, the water drives the spiral blades in the pipe to break up some frozen ice. The flow meter can calculate the current flow rate and feed it back to the intelligent controller. The sensor detects whether there is external water leakage in the connecting pipe and feeds it back to the intelligent controller. Then, the intelligent controller opens the electric valve to perform fire extinguishing operation.

[0013] By adopting the above technical solution, the beneficial effects of this invention are as follows: This invention sets a trigger value on a temperature sensor. When the temperature reaches a critical value, the temperature data transmitted by the temperature sensor is fed back to the intelligent controller. The intelligent controller then controls a deep-water pump to pump water into a fire-fighting water tank. The water-cooled wall is activated to heat the water in the fire-fighting water tank. The water is then pumped into the connecting pipe for de-icing. Simultaneously, the water drives the spiral blades inside the pipe to break up some frozen ice, allowing it to circulate within the connecting pipe. The flow meter calculates the current flow rate and feeds it back to the intelligent controller. If the flow rate is insufficient, the temperature of the fire-fighting water tank needs to be increased because the connecting pipe expands when frozen. Sensors detect external leaks in the connecting pipe and feed them back to the intelligent controller. If a leak is found, manual repair is required. When firefighting is needed, the intelligent controller opens the electric valve to initiate the fire-fighting operation. This method is highly efficient and eliminates problems of missed monitoring, missed inspections, and leaky pipes, while also ensuring effective anti-freezing. Furthermore, in the event of a sudden fire, the fire-fighting water supply equipment can respond quickly, despite limitations imposed by climate, time, and space.

[0045] This invention provides an intelligent control system for fire-fighting and antifreeze water supply in highway tunnels in cold regions, comprising a deep well 1, a fire water tank 2, a temperature sensor 3, a level sensor 4, a flow meter 5, an intelligent controller 6, connecting pipes 7, and sensors 8. The deep well 1 is equipped with a deep water pump 11, and the fire water tank 2 is equipped with a water-cooled wall 21. The fire water tank 2 is connected to the deep water pump 11 and is equipped with a water pump 22. The temperature sensor 3 and the level sensor 4 are respectively located in the deep well 1 and the fire water tank 2. The flow meter 5 is installed in the outlet of the deep well 1 and the fire water tank 2. The intelligent controller 6 is connected to control each of the deep water pump 11, the water-cooled wall 21, the water pump 11, the temperature sensor 3, the liquid level sensor 4 and the flow meter 5. The connecting pipe 7 is located on both sides of the tunnel. The connecting pipe 7 is connected to the water pump 11 and is connected to the fire water tank 2 for circulation. The connecting pipe is equipped with multiple electric valves 71. Multiple spiral blades 72 are installed inside the connecting pipe 7. The sensor 8 is installed on the connecting pipe 7.

[0046] By setting a trigger value on temperature sensor 3, when the temperature reaches a critical value, the temperature data transmitted by temperature sensor 3 is fed back to intelligent controller 6. Then, intelligent controller 6 controls deep water pump 11 to pump water into fire water tank 2, and activates water-cooled wall 21 to heat the water in fire water tank 2. The water is then pumped out by water pump 22 to connecting pipe 7 for de-icing. At the same time, the water drives the spiral blades 7 in the pipe to break up some frozen ice, allowing it to circulate in connecting pipe 7. The flow meter 5 calculates the current flow rate and feeds it back to intelligent controller 6. If the flow rate is not high enough, the temperature of fire water tank 2 needs to be increased because the connecting pipe 7 expands when frozen. Sensor 8 detects whether there is external water leakage in connecting pipe 7 and feeds it back to intelligent controller 6. If there is a leak, manual repair is required. When fire needs to be extinguished, intelligent controller 6 opens electric valve 71 to extinguish the fire. This method is highly efficient and has no problems with missed monitoring, missed inspection, or leaky pipes. It also ensures effective anti-freezing. In addition, in the event of a sudden fire, the fire water supply equipment can respond quickly due to limitations of climate, time, and space. In addition, multiple flow meters 5 are installed on the connecting pipes 7 on both sides of the tunnel, which makes it easy to record the flow at each location for quality inspection.

[0047] According to some embodiments of the present invention, optionally, the intelligent controller 6 is provided with a recording module, an alarm module, and a transmission module. It is used to record the on-site situation and test results daily. If a problem occurs, an alarm will be triggered via the alarm module, and then feedback will be sent to the terminal via the transmission module for manual emergency handling.

[0048] According to some embodiments of the present invention, optionally, the temperature sensor 3, the liquid level sensor 4, and the flow meter 5 are all equipped with a wireless module and a positioning module. The wireless module and the positioning module enable the location of the devices for rapid maintenance.

[0049] According to some embodiments of the present invention, optionally, the surface of the helical blade 72 is provided with a pushing groove 73. This facilitates the water flow to drive the helical blade 72 to rotate, breaking up the ice.

[0050] According to some embodiments of the present invention, optionally, the sensor 8 is annular and has multiple sensing strips 81, which are closely attached to the outer wall of the connecting pipe 7. This facilitates the detection of pipe ruptures and leaks, enabling timely repairs, and also provides timely feedback when the sensing strip 81 breaks.

[0051] According to some embodiments of the present invention, optionally, the flow meter 5 is also installed at the connection of the connecting pipe 7. The inner wall of the flow meter 5 is provided with a groove 51, a pressure sensing module 52 is provided in the groove 51, and a sensing ball 53 is provided in the groove 51. The sensing ball 53 is connected to the groove 51 by a spring 54. This allows the flow meter 5 to sense the water flow rate and water pressure in a timely manner, providing timely feedback for subsequent operations.

[0052] This invention also provides an intelligent control method for antifreeze water supply in a fire-fighting water supply intelligent control system for highway tunnels in cold regions. When the temperature reaches a critical value, the temperature data transmitted by the temperature sensor 3 is fed back to the intelligent controller 6. Then, the intelligent controller 6 controls the deep water pump 11 to pump water into the fire water tank 2, and starts the water-cooled wall 21 to heat the water in the fire water tank 2. Then, the water is pumped out to the connecting pipe 7 by the water pump 22 to melt the ice. At the same time, the water drives the spiral blades 7 in the pipe to break up some frozen ice. The flow meter 5 can calculate the current flow rate and feed it back to the intelligent controller 6. The sensor 8 detects whether there is external water leakage in the connecting pipe 7 and feeds it back to the intelligent controller 6. Then, the intelligent controller 6 opens the electric valve 71 to perform fire extinguishing operation.
