The technology relates to a submersible water lifting assembly and automatic fire fighting system for unmanned platforms having said system (1) that is efficient yet simple to install, energy saving, noise free and economical. The submersible water lifting assembly can comprise a High flow Ratio ejector Pump (30/30A) that utilizes under water arrangements of unmanned platform and enables the fire-fighting system to efficiently lift water from the sea water; using the force of existing water injection system; eliminating the requirement of diesel engine driven pump, for lifting the water. It avoids fire risk of the safety system itself, even in conditions of a large fire, unlike that of the prior art.

This relates to apparatus that can form dilute aqueous firefighting compositions from an aqueous concentrate.

A fire extinguishing system of an air mobility vehicle includes a refrigerant flow line in which a refrigerant flows, and including a compressor, a condenser, a first expansion valve, and an evaporator, a fire extinguishing liquid flow line connected to the refrigerant flow line via a connection valve, and configured to spray a mixed liquid of a fire extinguishing liquid and the refrigerant, a mixing part connected to the fire extinguishing liquid flow line, and configured to mix the refrigerant and the fire extinguishing liquid, and a fire extinguishing liquid storage part configured to store the fire extinguishing liquid and to discharge the fire extinguishing liquid into a mixing space of the mixing part.

An energy storage system includes at least one battery rack including at least two battery modules, a container in which the battery rack is received, an air conditioner including an outside heat exchanger configured to cool a heat exchanger medium having a temperature rise in the container, and a circulation path configured to allow the heat exchanger medium to circulate between the container and the outside heat exchanger, a fire extinguishing unit including a fire extinguishing agent tank configured to detect a temperature of the at least one battery module that is equal to or higher than a predetermined temperature or smoke that is generated in the at least one battery module and feed the fire extinguishing agent to the battery module, and an air conditioner management unit configured to spray the fire extinguishing agent in the fire extinguishing agent tank onto an outer surface of the outside heat exchanger.

A fire suppression apparatus is described that includes a base and a lid. The base has an opening and walls defining an internal area. The base also includes a sleeve with a portion positioned in the internal area and around a perimeter of the walls, and the sleeve defines a region of the internal area for placing an object. The sleeve also has an opening for placing the object into the region. The base further has a first fire suppressing powder positioned in the internal area between the sleeve and the walls. The lid covers the opening of the base, and has a cavity, a second fire suppressing powder contained inside the cavity, and a divider positioned to cover the cavity of the lid. Methods for suppressing a fire of an object are also described.

A fire extinguisher apparatus that consists on a loading lever network that gets built in the transport equipment allowing manipulation of the device that is directly introduced to the fire to compress it and by this, stopping the combustion process. Simultaneously, the said extinguishing apparatus will inject a series of substances over the flames, drastically reducing temperature of the fire zone, avoiding reignition when the device collapses on the different interventions these have.

The Main Lever of such network is originally built in to the transport equipment and one end will branch different tips which will form a net of smaller lever which will hang the TFI device. A tension cable will go across the upper part of the Main lever to bring more resistance and provide much more strength by preventing arcing of the lever when handling very heavy loads. A pipeline network that extends and is supported over and through the lever network, transports the cooling substances from the fluid deposits until the injecting sprinklers are arranged in the upper part of the attack devices.

A method for efficiently treating spontaneous ignition of the remaining coal in a large area goaf of a shallow-buried coal bed, which method integrates leaking stoppage, airflow control and fast inerting and cooling so as to efficiently prevent and treat the spontaneous ignition of the remaining coal in the large area goaf of the shallow-buried coal bed.

The invention is a container having an opening at one end and a flap or other closure to close the opening, the interior of the bag includes a liner filled with free-flowing expanded glass granulate having fire extinguishing properties, the liner is compartmentalized to separately retain the free flowing granulate to defined regions of the bag interior and it is formed from a sacrificial material that is combustible and will disintegrate upon exposure to the heat of a fire whereby when a electronic or other device that has caught fire is placed inside the bag, the free-flowing expanded glass granulate contained by the liner is caused to be released onto the device to extinguish the fire.

A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.

The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders and/or a directional control assembly to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, balancing feet, a removable nozzle, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.
