Description

Technical Field

[0001] The utility model relates to the technical field of fire protection of industrial and commercial integrated cabinets, in particular to a novel automatic patrol fire extinguishing system. Background Art

[0002] Currently, the following problems exist in the fire protection of integrated industrial and commercial energy storage cabinets: 1. Untimely fire extinguishing: When cluster-level fire extinguishing is required, manual water firefighting is required, and the flames cannot be extinguished immediately. 2. Inability to accurately extinguish fires: When cluster-level fire extinguishing is required, the water firefighting pipes are arranged above the energy storage cabinet. When the water firefighting is activated, the entire energy storage cabinet will be flooded and soaked, causing damage to areas where no fire has occurred. 3. Life safety risks: The battery cells inside the energy storage cabinet are connected in series and parallel. When a fire occurs, the fire spreads quickly. Manual firefighting will inevitably increase the time difference for the fire to spread, posing a serious safety risk to firefighters. 4.

[0012] Figure 2 This is a structural diagram of the interface where the automatic patrol fire extinguishing controller is located. DETAILED DESCRIPTION

[0013] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-2 As shown, a new type of automatic patrol fire extinguishing system includes a plurality of liquid fire extinguishing spraying devices 2 and a flame monitoring device 3 arranged in an industrial and commercial storage integrated cabinet 1, the output end of the flame monitoring device 3 is connected to the input end of the automatic patrol fire extinguishing controller 4, the output end of the automatic patrol fire extinguishing controller 4 is connected to the electric valve 6 on the liquid inlet pipe 5, and the end of the liquid inlet pipe 5 is connected to the liquid fire extinguishing spraying device 2. A plurality of gas automatic fire extinguishing devices 7 are also provided in the industrial and commercial storage integrated cabinet 1, the output end of the automatic patrol fire extinguishing controller 4 is connected to the electric starting component of the gas automatic fire extinguishing device 7, and a liquid outlet connected to the liquid outlet pipe 8 is also provided on the surface of the industrial and commercial storage integrated cabinet 1, and a filter device 9 is provided at the liquid outlet position.

[0015] Preferably, the flame monitoring device 3 is a temperature sensor and / or a smoke sensor. With this design, when a fire, overheating, or other conditions occur, the flame monitoring device 3 detects the high temperature environment generated by the fire in the integrated industrial and commercial storage cabinet 1 and sends a signal to the automatic patrol fire extinguishing controller 4. The automatic patrol fire extinguishing controller 4 controls the electric starter to activate, causing the gas automatic fire extinguishing device 7 to generate gas and initiate the fire extinguishing process.

[0016] Preferably, the automatic patrol fire extinguishing controller 4 is a PLC controller. More preferably, the PLC controller can be a Siemens S7-300 PLC controller.

[0017] Preferably, the automatic gas fire extinguishing device 7 is an aerosol fire extinguishing device, containing an aerosol generator in contact with an electric actuator, whose activation line is connected to the output of the automatic patrol fire extinguishing controller 4. More preferably, the electric actuator is an electric ignition head. With this design, the automatic patrol fire extinguishing controller 4 can control the electric actuator to ignite, causing the aerosol generator in contact to combust, thereby generating a gaseous fire extinguishing substance (e.g., aerosol or gas), which is ejected from its nozzle to extinguish the fire. The electric actuator can be a bridged or bridgeless electronic ignition head.

[0018] Preferably, the output end of the automatic patrol fire extinguishing controller 4 is also connected to an alarm. After designing like this, when there are situations such as fire, overheating, etc., the automatic patrol fire extinguishing controller 4 can control the alarm to work, thereby reminding the staff to come and check, to further take relevant measures.

[0019] Preferably, the liquid fire extinguishing spraying device 2 is a nozzle structure, and the liquid is sprayed out from here by opening the electric valve 6 on the liquid inlet pipe 5.

[0020] The working principle of this embodiment is as follows:

[0021] When the battery in the industrial and commercial storage cabinet 1 suffers from thermal runaway, the flame monitoring device 3 detects that a high temperature environment (for example, reaching 180°C ± 10°C) is generated in the industrial and commercial storage cabinet 1 due to the fire, and sends a signal to the automatic patrol fire extinguishing controller 4. The automatic patrol fire extinguishing controller 4 controls the electric starter to start, so that the gas automatic fire extinguishing device 7 produces gas to carry out the fire extinguishing process and prevent the spread of fire; and transmits the start signal and the fire address code feedback to the human-computer dialogue interface display of the automatic patrol fire extinguishing controller 4, and records the number and location of the gas automatic fire extinguishing device 7 started, and the historical records can be queried.

[0022] When the automatic patrol fire extinguishing controller 4 receives a signal indicating that all gas automatic fire extinguishing devices 7 within a cluster with a specific address code have activated their spraying, while the flame monitoring device 3 is still providing fire status feedback, it sends an activation signal to the electric valve 6 at the corresponding address code. The liquid inlet pipe 5 then supplies water to the liquid fire extinguishing spray device 2, causing it to automatically spray liquid to extinguish the fire, thus achieving secondary cluster protection. Once the flames within the cluster are completely extinguished by the liquid spray, the flame monitoring device 3 transmits a signal back to the automatic patrol fire extinguishing controller 4, which then sends a shutdown signal to the electric valve 6 at the corresponding address code, automatically shutting down the liquid fire extinguishing spray device 2 at that address code. Simultaneously, the automatic patrol fire extinguishing controller 4 displays this signal on its human-machine interface and records the number and location of activations by the automatic patrol fire extinguishing controller 4, making the historical record accessible. This precise automatic liquid spraying extinguishes the fire without affecting other clusters where no fire is occurring, significantly reducing human, material, and property losses while also avoiding the personal safety risks associated with manual operation.

[0023] If an emergency occurs and you need to immediately start or stop the liquid spraying fire extinguishing, you can manually operate the start and stop buttons on the automatic patrol fire extinguishing controller 4 host to achieve remote manual control of start and stop.

[0024] When the liquid fire extinguishing spray device 2 is activated within the cluster to spray and extinguish a fire, the waste liquid generated passes through a filter device 9 (e.g., a water purifier) ​​to filter and purify the waste liquid. The waste liquid then automatically flows out of the integrated commercial and industrial storage cabinet 1 through a liquid outlet pipe 8. This prevents a large amount of liquid from spreading within the integrated commercial and industrial storage cabinet 1 and causing damage to other equipment. Furthermore, the filtered and purified liquid does not cause secondary pollution to the environment.

[0025] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
