Mobile-Automatic Power Supply for Sump Pump

Abstract

A mobile power supply device and method for energizing a sump pump in a sump pit during a power outage, and a mobile power supply device and method for energizing a sump pump secured to a bottom portion of the device. The device includes an enclosure similar to a dolly that is manufactured from plastic or similar non-electrically conductive material to minimize weight to enable the manual lifting and pulling of the mobile power supply device, and to promote safety by reducing the chance of an electrical short circuit when supplying electrical power to a sump pump. The enclosure includes a carrying handle and a relatively large dolly handle that cooperate with castors attached to a bottom portion or bottom surface of the enclosure. The castors promote manual movement of the device upon a substantially horizontal surface or up and / or down stairs leading to a sump pump in a sump pump well or pit in a basement.An alternative mobile-automatic start and stop power supply for a sump pump includes a mobile enclosure that a person can lift with a battery, a battery charger an electrical inverter disposed in said enclosure. The electrical inverter is sized to energize the sump pump in the sump pump well and to charge the battery. The inverter includes an internal transfer switch for disconnecting electrical power from an existing electrical receptacle that supplies power to the sump pump, and connecting the electrical inverter to the sump pump after disconnecting the existing electrical receptacle from the sump pump; whereupon, the inverter continually lowers the water level in the sump pump well until power to the existing electrical receptacle is restored or until the battery is discharged to voltage levels incapable of energizing the sump pump.

Description

[0001]This is a Continuation-In-Part Application of parent application Ser. No. 16 / 194,275, filed on Nov. 16, 2018, which is based on U.S. Provisional Application No. 62 / 587,637, filed on Nov. 17, 2017.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to back-up power supplies for sump pumps, and more particularly, to a manually portable or mobile power supply that can be disposed to automatically energize an existing sump pump motor to remove water from an existing sump well. The present invention includes a sump pump in the mobile power supply enclosure that enables the mobile power supply to remove water from a flooded area by manually position the mobile power supply in the flood water and closing a switch that energize the sump pump in the enclosure.2. Background of the Prior Art[0003]A myriad of prior art back-up power supply designs for sump pumps are commercially available. Prior art power supplies are installed adjacent to the sump pump...

AI Technical Summary

Benefits of technology

The present invention is a back-up power supply for sump pumps that can automatically start the pump when the main power source is interrupted and the water level is high. The power supply includes a mobile enclosure containing a sump pump and a battery power source. The enclosure is designed to be placed in water in a flooded area to remove the water and promote the functioning of the sump pump. It also includes a level sensor and a level controller to start the sump pump when the water level reaches a predetermined high level. The power supply can be easily moved around and can also notify a person about a high water condition in a sump well through a wireless system. Additionally, the power supply includes a detachable handle and wheels for easy movement and a second sump pump for removing water from a flooded area.

Problems solved by technology

Prior art power supplies are installed adjacent to the sump pump for automatic starting of the sump pump in the event that the main power source is interrupted and a high water level is detected in the sump well, but these power supplies are not mobile.

Other back-up power supply designs are mobile and can be manually disposed at flooded areas, but these mobile power supplies do no automatically energize an existing sump pump motor when the main power source to that sump pump motor is interrupted.

In addition, prior art back-up power supplies do not include a sump pump in the enclosure containing the batteries to enable the enclosure to be manually disposed in flood waters, then energizing the sump pump in the enclosure by manually moving a switch to an “on” position to remove flood water.
