The invention provides a lithium battery two-component fire extinguishing agent and a fire extinguishing composition adopted by the lithium battery two-component fire extinguishing agent. The fire extinguishing composition provided by the invention is prepared from the following raw materials in parts by weight: 1 to 2 parts of guar gum, 2 to 3 parts of polyvinyl alcohol, 3 to 4 parts of acrylamide, 2 to 3 parts of methacrylic acid, 1.5 to 2 parts of a framework supporting material, 1.3 to 2.5 parts of a cross-linking agent and 0.2 to 0.3 part of an initiator. The fire extinguishing composition provided by the invention has a stable three-dimensional structure, evaporation of water in the structure can adsorb a large amount of heat, and the heat is attached to the surface of a battery to form carbon deposition along with reduction of the evaporation volume of the water, so that the effects of isolating air and obstructing combustion are achieved, the flame retardance can be improved, and re-combustion can be prevented; the high polymer consumes combustible gas in the process of burning and heating to form carbon, so that the burning reaction is prevented. The fire extinguishing hydrogel or the double-component fire extinguishing agent comprising the water-based component and the hydrogel component can be prepared from the water-based fire extinguishing agent, and the water-based fire extinguishing agent and the hydrogel component have multiple synergistic fire extinguishing effects on the lithium battery, so that efficient fire extinguishing of the lithium battery is realized.

The utility model discloses a communicating blow-off valve, which relates to the technical field of blow-off valves, and comprises a valve head body arranged on a rack, a liquid inlet assembly comprising at least one liquid inlet, and each liquid inlet is arranged on the side surface of the valve head body in a penetrating manner; the nozzle assembly comprises a nozzle seat and a plurality of nozzles mounted on the nozzle seat in a surrounding manner; the temperature and electricity double-starting control assemblies are installed on the front side and the rear side of the valve head body, each temperature and electricity double-starting control assembly comprises an electric driving structure and an external induction driving structure, and through the design that the temperature and electricity double-starting control assemblies are installed on the front side and the rear side of the valve head body, the valve head body has the temperature and electricity double-starting function in the using process; the fire extinguishing device can be electrically started through DCV or automatically started through temperature control, multiple functions are integrated, two control modes are adopted, the spraying function is more rapidly and effectively achieved in the using process, time and labor are saved, and efficient fire extinguishing is achieved through double-function control.

The invention relates to the field of offshore platform fire fighting, in particular to a fire extinguishing control system and method for a turbofan cannon. Comprising a controller used for analyzing field data and displaying images; the detection module is used for sensing the temperature, the image and the distance of a field fire, and the detection module is connected with the controller; the processing module is used for receiving the data from the detection module, analyzing and processing the data and then generating a driving instruction for the turbofan gun to aim at the fire, and the processing module is connected with the controller; when an offshore platform has a fire, the system can analyze flame characteristics of a fire area at the first time, filter interference of factors such as environment and wind power, position and aim at the fire center area, command a turbofan cannon to jet, adjust a fire extinguishing system in real time according to flow parameters of the turbofan cannon and flame motion characteristics, and improve the fire extinguishing efficiency of the offshore platform. Accurate fire recognition, accurate aiming, effective spraying and fire suppression can be achieved, the fire extinguishing precision is improved, and the fire extinguishing efficiency can be further improved.

The utility model belongs to the technical field of fire fighting apparatus, especially is involved in an improved fire fighting hook structure for electric vehicle. The combined hook lance is composed of hollow metal conical seat, sliding rail, tow hook, injection hole seat and penetrating cone. The sliding rail is welded to the outer surface of the hollow metal conical seat, the tow hook is connected to the sliding rail through bolts, the hollow metal conical seat is provided with the injection hole seat which is in communication with the hollow, and the penetrating cone is screwed to the upper end of the injection hole seat. The fire fighting hook is designed with hollow pipeline, which can quickly inject special fire extinguishing agent after piercing the battery pack shell, accurately extinguish the fire source and prevent the fire from rekindling. The hollow structure is integrated with an insulation layer, effectively preventing electric shock risk and significantly improving rescue safety and efficiency.
