A portable fluid pump comprises a tank, a positive displacement pump comprising a fluid inlet and outlet, and an electric motor that drives the positive displacement pump, wherein the electric motor is a brushless variable speed electric motor operating at 110 volts or less. A conduit diverts fluid pumped by the positive displacement pump back into the tank and an actuated valve assembly controls fluid flow through the conduit and, therefore, a pressure of fluid flow through the fluid outlet. A pair of sensors measure, respectively, a pressure and a flow rate of fluid flow through the fluid outlet. A system controller receives a target fluid pressure and fluid flow rate and adjusts a throttle position of the actuated valve assembly and a speed of the electric motor such that pressure and flow rate readings from the sensors substantially match, respectively, the target fluid pressure and fluid flow rate.

A fire suppression system, a method for deploying the fire suppression system, an adapter for use in the fire suppression system and a method for increasing local humidity using the fire suppression system, as well as uses of the adapter for transferring water to vehicles or aircraft are described. The fire suppression system is formed of segments of water transfer conduit extending from a main water source. The system includes a plurality of connections between at least some of the segments of water transfer conduit made using an adapter placed at a fixed location. In the system. the adapter has a main water dispensing device mounted thereon. The main water dispensing device is in water transfer communication with the water transfer conduit and the adapter includes one or more connection points for transfer of water via branch conduits extending outward from the adapter or inward to the adapter from a secondary water source.

The presently disclosed invention relates to emergency housing units and methods of providing emergency shelter, where the emergency housing units comprising a shipping container, a front wall disposed at the front side having a door, a canopy pivotally connected to one of the shipping container and the front wall at a location adjacent to both a top portion of the shipping container and the front wall, the canopy able to pivot from a closed retracted position to an open extended position, and a canopy latch attached to the first gate and the second gate, the canopy latch engaging with the canopy and releasably lockably fixing the canopy and both gates in a fixed position relative to one another and preventing the gates from moving into a closed position.

A modular fluid spray nozzle is constructed from an inner conduit, having a sidewall with a center hole, housed inside a center conduit that includes a window defined by a sidewall, and a flexible or rigid outer conduit wrapped around the center conduit and forming a chamber with the rectangular window. The chamber is in fluid communication with the center hole and with at least two apertures defined by the outer conduit. The inner conduit is configured to be coupled to any type of conduit material, such as PVC pipe or another modular fluid hose segment.

A fire-retardant webbed apparatus for use on a structure includes at least one tube surrounding a channel; at least one inlet port on the at least one tube, the at least one inlet port being in fluid flow communication with the channel, and the at least one inlet port being sized and configured for receiving a flow of fluid; a plurality of apertures formed along the length of the one or more tubes, the plurality of apertures each being in fluid flow communication with the channel; and wherein the flow of a fluid into the channel through a selected one of the at least one inlet ports causes the fluid to be emitted through plurality of apertures onto the structure and surrounding area for preventing the spread of fire onto the structure.

An extinguishing system and method for extinguishing fires. The extinguishing system includes—a pump system for pumping extinguishing agent; one or more nozzles connected operatively to the pump system for the purpose of spraying extinguishing agent at a source of fire; a supply or inlet arranged on the pump system for the purpose of supplying extinguishing agent to the pump system; an extinguishing conduit with an extinguishing length arranged on the pump system for the purpose of supplying extinguishing agent to the at least one nozzle; and an extinguishing controller provided with an input system for inputting system data, including data about the extinguishing conduit, the pump system and the at least one nozzle. The extinguishing controller is configured to determine with the system data an operating pressure at or close to the at least one nozzle and thereby control the pump system.

Disclosed is an adjustable and portable fire protection sprinkler system. The device consists of a sprinkler head mounted on an adjustable height center pole connected to adjustable legs, forming a foldable tripod-like configuration. The legs and center pole have inner and outer tubes arranged for telescopic movement relative to each other, for adjusting the height of the pole and the lengths of the legs. The sprinkler head is connected to a rubber hose which is threaded through the top of the center pole and connected to a water source at the bottom. The tube stretches and retracts inside the pole corresponding to the pole height. A collar around the pole connected to the legs, wherein the legs connected to the end of the pole by metal strips. This allows for sliding up and down; increasing or decreasing the triangular base parameter. The base is also defined by the length of the legs and is adjusted to maintain the tripod stability.

Systems and methods are disclosed for fire suppression. One method of fire suppression may include sensing initial environmental parameters in an area of interest, and determining whether or not to enable the fire suppression system, based at least in part on the sensed initial parameters. Then subsequently sensing subsequent environmental parameters, and determining whether to enable or disable the fire suppression system, based at least in part on the sensed subsequent environmental parameters.

A personal fire-fighting system can extinguish fires in order to save structures such as homes or business buildings. The personal fire-fighting system includes a frame, a water pump system, a suction hose, a high-trajectory nozzle, a rotor sprinkler, and a length-adjustable tube. The frame protects and holds the water pump system, the length-adjustable tube, and the rotor sprinkler in place. The water pump system drives water from the suction hose in order to be outputted by the rotor sprinkler. The suction hose is a fluid conduit between a body of water and the water pump system. The high-trajectory nozzle increases the trajectory angle of water that is outputted by the rotor sprinkler. The rotor sprinkler rotates and outputs streams of water in order to cover large areas. The length-adjustable tube allows the rotor sprinkler to output water at higher areas if needed.

A system for increasing humidity for fire suppression is provided, as well as a process for deploying the system. The system includes a main line formed of lengths of conduit having an inner diameter of at least about 8 inches (about 20 cm). At least some of the lengths of conduit are connected to each other using an adapter connected to a water dispenser in water transfer communication with the main line, thereby providing a plurality of water dispensers along the main line. The system includes one or more inline pumps or branch line pumps for boosting water pressure in the main line to provide water pressure at each water dispenser of at least about 80 psi (about 550 kPa). The deployment process includes steps of determining equipment quantities and transport of the equipment to the vicinity of a water source for deployment.
