Multi-stage intelligent fire extinguishing system and control method

Abstract

The invention discloses a multi-stage intelligent fire extinguishing system and a control method. The system comprises a trigger fire extinguishing device I with an outlet connected to an exploring tube, wherein the exploring tube surrounds the surface of each lithium battery module in a lithium battery cabinet; a smoke transducer I, a controller and a smoke transducer II are arranged at the top of the outer wall of the lithium battery cabinet; a temperature sensor I is arranged at the top of an inner cavity of the lithium battery cabinet; a trigger type fire extinguishing device III and an alarm are arranged at the lower end of the outer wall of the lithium battery cabinet; a detection device II of the trigger type fire extinguishing device III extends into the inner cavity of the lithiumbattery cabinet; each lithium battery module is provided with a temperature sensor II and a trigger type fire extinguishing device II; a detection device I of each trigger type fire extinguishing device II extends into the corresponding lithium battery module; and the other end of the exploring tube is provided with a pressure switch. The system has the advantages that the fire extinguishing effectiveness of the intelligent fire extinguishing system can be improved, and graded early warning or fire extinguishing actions can be carried out according to different states in combination with different use working conditions of different devices in various triggering modes from inside to outside and through intelligent detection logic control of the controller.

Description

technical field [0001] The invention relates to the field of intelligent fire extinguishing, in particular to a multi-stage intelligent fire extinguishing system and a control method. Background technique [0002] With the increasing awareness of fire protection in the whole society, fire fighting devices have been used in various fields of life. Now the more common fire fighting devices are mainly used to extinguish primary fires. For deep fire extinguishing, special equipment and personnel are required to go to the scene to extinguish fires. ; According to the principle of fire extinguishing, combined with the scene to be guaranteed, the present invention performs multi-level intelligent fire extinguishing, and can carry out intelligent deep fire extinguishing through automatic control and physical trigger mode. At present, lithium batteries have been widely used in various fields of life, and the application of lithium batteries must have corresponding fire extinguishing ...

Problems solved by technology

[0003] As a new type of power and energy storage device, lithium batteries have been widely used in various industries, but one of the biggest obstacles to the development of lithium batteries is that they are prone to thermal runaway, so fire protection devices have become a standard configuration of lithium battery equipment; As a power device, lithium batteries have been widely used in new energy vehicles, but the application in the energy storage industry, especially the mobile energy storage industry has just begun; the application of the energy storage industry has a very large overall capacity, and the effectiveness of the fire extinguishing system It is especially important. At present, the existing single fire extinguishing system for lithium battery fire extinguishing cannot guarantee the effectiveness of energy storage device fire extinguishing.
