The present invention provides systems and methods for preventing fire outbreak and suppressing fire in liquid-fuel activated vehicles.

A packaging unit for one or more of transport or storage of at least one organic peroxide. The packaging unit comprises one or more outer container, such as a transport container and/or a storage container. The packaging unit may also comprise an inner container. The outer container and/or the inner container is filled with the at least one organic peroxide. The packaging unit also comprises one or more extinguishing agent container filled with an extinguishing agent. The extinguishing agent container may be at least one bag and/or at least one bottle. The extinguishing agent container is separately introduced into one or more of a receiving area of the outer container or the inner container. The extinguishing agent container is removable from the outer container. The extinguishing agent container may be detachably connected to or not connected to the outer container, or the extinguishing agent container may be detachably connected to or not connected to the inner container. The extinguishing agent is released from the extinguishing agent container by heat-induced melting, bursting, burning or tearing of the extinguishing agent container.

A fracturing device, a firefighting method thereof, and a computer readable storage medium are disclosed. The fracturing device includes a power unit, the power unit includes a muffling compartment, a turbine engine, and a firefighting system; the firefighting system includes a firefighting material generator, at least one firefighting sprayer and at least one firefighting detector, the at least one firefighting sprayer and the at least one firefighting detector are located in the muffling compartment, each of the at least one firefighting sprayer is connected with the firefighting material generator and configured to spray out firefighting material generated by the firefighting material generator.

A firefighting system includes a controller, a battery, and a firefighting device connected to the battery. When a temperature of the battery reaches a temperature threshold indicating that the battery is on fire, the firefighting device releases an extinguishing agent to the battery to extinguish the fire. The controller is configured to obtain a pressure value in the firefighting device. When the pressure value in the firefighting device meets a preset condition, the controller generates warning information indicating that the firefighting device or the battery is faulty.

An equipment dry bay is provided. The equipment dry bay includes at least one partition that subdivides the equipment dry bay into a plurality of compartments, wherein the at least one partition includes a plate, and at least one flame arrestor positioned within the plate and providing vapor and fluid communication between a first compartment and a second compartment of the plurality of compartments, the at least one flame arrestor configured to vent combustion gases in the first compartment into the second compartment.

A landing pad including at least one integrally formed elongated hollow decking unit having an elongated landing plate with a plurality of holes, an elongated base plate aligned longitudinally with respect to the elongated landing plate which is designed as an orifice plate and spaced a distance apart from the elongated landing plate, and two elongated side wall plates connecting the elongated landing plate to the elongated base plate. The plurality of holes may be configured to drain unburned fuel spilled on the elongated landing plate through the plurality of holes into the elongated hollow decking unit and to suppress flame of burning fuel from propagating through the plurality of holes into the elongated hollow decking unit by reducing the temperature of drained unburned fuel. The distance apart between the elongated landing plate and the elongated base plate may be configured to prevent re-ignition of the drained unburned fuel on the elongated base plate inside the elongated hollow decking unit.

A fracturing device, including a power unit, wherein the power unit comprises a muffling compartment, a turbine engine, an air intake unit, and a starter; the air intake unit is communicated with the turbine engine through an intake pipe, and configured to provide a combustion-supporting gas to the turbine engine; the air intake unit is located at the top of the muffling compartment, the muffling compartment comprises an accommodation space, the turbine engine and the starter are located in the accommodation space, and the starter is configured to start the turbine engine, the starter comprises a first electric motor.

An enclosure, vehicle, and method for containing an overheating device are provided. An enclosure includes a body and a door that form a volume. The body includes is connected to a Venturi tube that is in communication with a fluid flow path flowing across an opening at an opposite end. In the event an overheating device is placed in the enclosure, a pressure sensor measures a pressure in the volume and a controller opens a first valve in a flow path through the Venturi tube so that air is pumped from the volume via the Venturi effect. The first valve is closed when the measured pressure drops below a threshold pressure. The enclosure can also include an extinguishing agent that can be expelled into the volume if a temperature sensor measures a temperature above a threshold temperature.
