Remote pumping system for cisterns

Abstract

A remote pumping system for cisterns or water storage tanks is disclosed, comprising a high volume water pump driven by a hydraulic or electrically powered motor, for rapidly supplying a large volume of water to an extinguishment operation involving a burning object or building, from a local water source such as a pond, pool, portable basin, municipal hydrant, or cistern. The pump is lowered into a cistern by means of a rail system and is powered electrically or hydraulically by a remote or unit mounted power supply. In a further embodiment, a water-tight, above ground containment cabinet houses the discharge hose reels and / or the power supply for the pump motor.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 953003, filed on Jul. 31, 2007. The entire disclosure of the above application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to remote water delivery means and water pumping assemblies. More particularly, this invention relates to a remote water storage with an integrated high volume and pressure water delivery pump for use in fire protection and emergency situations.BACKGROUND OF THE INVENTION[0003]In emergency situations, such as when a building, vehicle, or other large object catches fire, a matter of seconds can determine not only whether the object is a total loss, but whether lives could be at risk. It is, therefore, imperative that personnel trained to put out the fire arrive on the scene as quickly as possible. Often, due to expanding population growth in rural areas not supplied with water by public utilities...

AI Technical Summary

Benefits of technology

[0005]It is therefore an object of the present invention to provide a submersible water pump of sufficient volume and pressure handling capabilities which can be placed into a remote cistern for extracting a supply of water stored there within.

[0007]Another object of the present invention is to provide a removable cistern pump which may be utilized in conjunction with prior art ‘drafting’ to significantly increase discharge volume.

[0009]It is a further object of the present invention to provide a hydraulically powered submersible pump for use with in-ground cisterns which is highly reliable and predictable in performance.

[0011]Finally, it is an object of the present invention to be able to retrofit the pump system onto existing cistern / storage tanks with minimal effort or equipment.

Problems solved by technology

This means of retrieving the water in an expedient manner and in sufficient volumes necessary to salvage the burning object proves difficult at best.

This historically has been fraught with human and mechanical failure with an undesirable frequency.

Furthermore, there is a physical limitation as to tank proximity with regard to the drafting apparatus.

In addition, the effort and time required to establish water delivery is increased due to the effort associated with ensuring suitable drafting characteristics (i.e., hardware connections, water-tight seals, etc.).

The problems previously encountered with poor water delivery from submersible water storage vessels relate primarily with the incompatible design features of submersible pumps with requirements for high volume and high pressure applications.

These submersible pumps are not designed to pump large volumes of water with the requisite pressure for fire-fighting applications (for example, sufficient pressure to enable delivery of water through tack lines of 250 feet of 1 and ¾ inch hose for fighting emergency fire situations).
