Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing equipment, and in particular to a cable trench intelligent fire extinguishing device and method based on perfluorohexanone multi-sensor linkage. Background Art

[0002] With the rapid development of power systems, cable trenches, as an important part of power transmission, are of vital importance for their safety. Cable trench fires will not only cause power outages, but may also lead to serious safety accidents. Traditional fire-fighting methods have problems such as slow response and low fire-fighting efficiency, and cannot meet the needs of modern power systems. Therefore, it is of great significance to develop an efficient and accurate cable trench fire-fighting device.

[0003] As a new type of fire extinguishing agent, perfluorohexanone stands out for its excellent environmental protection characteristics and fire extinguishing effect. It has zero ozone depletion potential (ODP) and a global greenhouse effect potential (GWP) close to 1, and its atmospheric survival life is extremely short. These characteristics make it an ideal long-term substitute for halons and hydrofluorocarbons (HFCs). In addition, perfluorohexanone is a colorless, odorless, non-conductive and non-corrosive chemical. As a gas insulating medium, perfluorohexanone can effectively isolate the contact between the power supply and the fire, preventing the power supply discharge from promoting the fire, making it an ideal choice for cable trench fire extinguishing.

[0004] The characteristics of cable trench fire are rapid spread of fire. Due to the small space and poor ventilation conditions of the cable trench, fire smoke easily accumulates, making it inconvenient for rescue personnel to enter and exit, and rescue is difficult after the fire occurs. In addition, there are a large number of wires and cables in the cable trench. After the traditional water fire fighting system extinguishes the fire, the damaged parts of the cable are washed by water, which will cause the insulation performance to deteriorate, making it difficult to restore it normally later. It is necessary to achieve the effects of waterproofing and drainage at the same time, the cost is high, and it is impossible to achieve targeted fire fighting at specific locations. Summary of the invention

[0042] The signal transmission cable 5 is connected to the cable trench fire extinguishing device unit 2 and the signal processing unit 3 and is used for transmitting fire signals and control instructions.

[0043] As an optional embodiment: the perfluorohexanone storage unit 1 includes a storage barrel, a pressure release valve 12 installed on the top of the storage barrel, a liquid level sensor 13 inserted into the storage barrel, a plunger pump 14 installed on one side of the storage barrel, and a pipeline 11 arranged between the plunger pump 14 and the storage barrel;

[0044] It should be noted that the perfluorohexanone storage unit 1 is designed as a sealed pressure vessel that can withstand the pressure changes of perfluorohexanone during storage and use. The unit is equipped with a pressure release valve 12, a liquid level sensor 13 and a plunger pump 14 to ensure storage safety and real-time monitoring of the inventory of the fire extinguishing agent. The storage unit is connected to the plunger pump 14 through a pipeline 11 so that the perfluorohexanone can be quickly released when needed.

[0045] The design of the storage unit takes into account the stability and safety under different environmental conditions. For example, the storage unit can maintain stable performance in high or low temperature environments. In addition, the storage unit is equipped with an automatic replenishment system that can automatically replenish the fire extinguishing agent after use, ensuring that it is always on standby.

[0047] Furthermore, the smoke detection modules 22 are arranged at the four corners of the device body;

[0048] Further, the temperature monitoring module 21 extends out from below the device body;

[0049] Furthermore, the number of the motor sliding modules 24 is three on the left and right;

[0050] It should be noted that the cable trench fire extinguishing device unit 2 is installed longitudinally at the entrance or key position of the cable trench, and the frame size of the unit is determined according to the specific size and structure of the cable trench. The smoke detection module 22, temperature monitoring module 21 and infrared patch sensing module 24 of the unit all use high-sensitivity sensors, which can promptly detect the smoke and temperature changes at the early stage of the fire, as well as the infrared radiation generated by the fire. The motor sliding module 23 includes three modules equipped with nozzles.

[0054] A method for using a cable trench intelligent fire extinguishing device based on perfluorohexanone multi-sensor linkage, comprising the following steps:

[0055] Fire detection stage: Once a fire occurs in the cable trench, the system will immediately start three key modules: smoke detection module 22, temperature monitoring module 23 and infrared patch sensing module 24. The smoke detection module 22 can detect smoke in the air, which is an early sign of fire; the temperature monitoring module 23 monitors the temperature changes in the cable trench; the infrared patch sensing module 24 detects fire by sensing thermal radiation; these three modules work together to provide comprehensive fire signal detection to ensure timely detection at the early stage of the fire.

[0056] Signal transmission stage: Once fire signals are detected, these signals will be transmitted to the signal processing module 3. The signals are transmitted through cables, which is a stable and reliable transmission method that can ensure the fast and accurate transmission of signals.

[0057] Signal processing stage: After receiving the fire signals from the detection module, the signal processing module 3 transmits these signals to the computer host 31. The computer host 31 analyzes and processes these signals to determine the location, intensity and possible spread trend of the fire.

[0058] Precision fire extinguishing stage: According to the analysis results of the computer host 31, the system will start the plunger pump 14 and control the nozzle on the motor slide module 25 to spray accurately. This precision spray can directly aim at the fire source, quickly and effectively extinguish the fire, and reduce damage to the surrounding environment.

[0059] System self-check stage: Before a fire occurs, the system will periodically perform self-checks to ensure that all modules, including the smoke detection module 22, the temperature monitoring module 23, the infrared patch sensing module 24, and the signal processing module 3, are in normal working order. This self-check mechanism helps prevent fires and ensures that the system can respond immediately when a fire occurs.

[0060] User interaction stage: The signal processing unit not only processes fire signals, but also interacts with users. It can provide real-time information on the fire status to help users understand the current situation. At the same time, users can issue instructions based on this information, and the system will perform corresponding operations based on the user's instructions, such as starting or stopping the fire extinguishing program.
