The technology of this disclosure pertains generally to firefighting, and more particularly to forest fire fighting where installed fire hydrants are remote.
Providing water for firefighting at remote locations where a wildfire incident may occur is frequently solved by emergency personnel “shuttling” water loads to designated drop points where water is not otherwise available. At such drop points emergency personnel will stage large open pools that act as temporary storage tanks. These temporary storage tanks are capable of holding thousands of gallons of water for personnel to draw from and return to the incident fire line. However, such water stations are highly deficient in nature, as they can only refill so many tank truck units to disperse back to the fire line before needing to be replenished via trucks circling back to refill them. During this “shuttling” operation trucks must drive to either a city water connection, or an accessible body of water from which to draw. However, locations that support the drafting of water by equipment such as a firetruck, or water truck, are in short supply. All too often rivers, streams, and large bodies of water are distant from accessible roadways that a firetruck, tank truck, or water truck would be able to transverse to obtain such natural water sources.
In this disclosure, a method and apparatus is described for delivering water or other fluid from a typically inaccessible source to an access point, known as a mobile fire hydrant. Such sources may be lakes, streams, ponds, pools, and the like that are down steep inclines that firefighting equipment cannot readily, and timely, access. Additionally, not all fires occur in regions where fire hydrants are extant. Hence, the mobile fire hydrant describes here serves the purpose of providing water access where firefighting infrastructure, such as installed hydrants, are not available.
The mobile fire hydrant may be used for continuous water supply to a mobile tank when warranted. Otherwise, the mobile fire hydrant is used only to fill a mobile tank, and then the remote pump is turned off to conserve fuel. The remote pump is actuated by a switch on the mobile fire hydrant. Although the switch is shown in the drawings below as permanently mounted on the mobile fire hydrant, it could be temporarily or permanently detached as the need occurs. As used herein, a “mobile tank” can include, without limitation, a movable tank, a tanker truck, a pumper truck, a fire truck, a water tender, a portable folding tank, a trailer mounted tank, or other container that is capable of holding water for dispensing. Reference to one type of mobile tank herein does not exclude another type of mobile tank being used in its place.
Further aspects of the technology described herein will be brought out in the following portions of the specification, wherein the detailed description is for the purpose of fully disclosing preferred embodiments of the technology without placing limitations thereon.
The technology described herein will be more fully understood by reference to the following drawings which are for illustrative purposes only:
During a wildfire incident, important resources including accessible water are often hours away from the site of the incident, or too far from roads to be viable as a firefighting water source. Having water close to an incident when needed it is of paramount importance to successfully fighting a fire. It is not uncommon for equipment to need to travel for an extended amount of time to wherever water is available for refilling. Sometimes this means forgoing drawing water from a closer source simply because the water is physically inaccessible. Valuable time and resources are often consumed by the act of obtaining water to fight the fire.
The mobile fire hydrant described herein is designed to meet the needs of emergency personnel without requiring access to city water connections that may not be close to the incident of the fire. The mobile fire hydrant can pull water from any source of water and dispense it to a remote location located hundreds of feet away and up steep inclines where flowing bodies of water often reside. The mobile fire hydrant described herein provides water on demand once setup in the required location.
The mobile fire hydrant dispenses water via a connection to a pump located at a station that may be quite distant from the hydrant. Through a series of hose connections and a proprietary electrical switch the mobile fire hydrant turns off and on as needed to dispense water through a standard firefighting fitting located on the mobile fire hydrant.
Typically, the pump is located within self-priming distance of a suitable water source, such as, but not limited to lakes, ponds, streams, rivers, pools, hot tubs, etc. Such pump would be limited in vertical distance to a maximum of about 32 vertical feet (atmospheric pressure at mean sea level) from the water source, but more practically to the self-priming head limit of the particular pump being used.
Alternatively, and not shown here, a submersible pump may be directly deposited in the water source, thereby eliminating the self priming head limit.
The mobile fire hydrant has multiple functions as well besides dispersing water to a remote location. The mobile fire hydrant can operate as: a sprinkler station; a fire-retardant mixing and dispensing station; a water supply to a helicopter-based retardant station; and as a station for transferring water to larger tanks for further distribution via an additional pump to an overhead fill station.
The mobile hydrant would be able to have a strategic placement near an available water source to replenish emergency personnel water supply to the limits of the water source. This alleviates the need for equipment to drive back and forth to fill temporary storage tanks, and any logistic challenges such mobile tanks may incur on their way back and forth to the city water sources, or other accessible drafting locations. The mobile fire hydrant also generally alleviates the need for the temporary storage tanks themselves.
In the following description, the “T” sections/elements comprise a vertical “stem” connecting to the top of the letter in the horizontal stroke, which is called an “arm”. The stem bisects the stem.
