Abstract
A jetter system for removing debris such as leaves, branches, mud, and trash from sewer pipes and from other types of pipes is disclosed. The jetter includes a rechargeable battery that provides direct current (DC), a DC/AC converter, and an AC motor that drives a water pump, or the like means for improved powering and debris removal.
Claims13
A system for cleaning debris from pipes and sewers, wherein the system is capable of removing debris from one or more of indoor plumbing, underground plumbing, out-of-doors plumbing, irrigation conduits, sewage systems that carry industrial wastewater, sewage systems that carry sanitary waste, and sewage systems that carry rainwater, wherein the system comprises, in combination:
- (A) A series of electrical devices that can be represented on a flow chart as being closely related, wherein these electrical devices comprise:
- (a) An alternating current (AC) battery charger that can accept either 120 volt or 240 volt AC power from any commercial or residential powergrid, wherein the battery charger converts incoming AC to the necessary DC output in order to recharge a battery pack,
- (b) A rechargeable battery pack that supplies direct current (DC),
- (c) A DC to AC converter that converts direct current from said battery pack to alternating current, and wherein the alternating current is used to drive an electic motor,
- (d) An electric motor that is driven by the alternating current (AC) produced by the DC to AC converter,
- (e) A water pump for pumping water from a water tank to a manifold, wherein the electric motor is coupled to the high pressure water pump via jaw couplings, gear drive, or belt drive in a manner to directly or indirectly drive the water pump shaft,
- (B) A series of fluid flow devices that can be represented on a flow chart as being operably linked, wherein these fluid flow devices comprise:
- (a) A water tank for storing water, wherein the stored water is used for said cleaning debris;
- (b) A manifold and a hose reel, wherein said water pump for pumps water from the water tank to a manifold and then to a hose reel;
- (c) Said manifold that is capable of receiving water from said pump, wherein the manifold is also capable of directing water to said hose reel, and wherein the manifold is also capable of directing water back to said water tank, wherein the percentage of water directed to hose reel and percentage of water directed back to water tank is controllable by the combination of a pressure sensor and a Programmable Logic Controller (PLC) assembly that comprises a PLC logic,
- (C) A plurality of regulatory devices that regulate water flow, the regulatory devices comprising:
- (a) A pressure sensor operably linked to the manifold, wherein the digital pressure sensor is operably linked to a PLC assembly,
- (b) Wherein the PLC assembly comprises an HMI screen, wherein the pressure sensor functions to measuring output water line pressure and displaying said pressure reading onto the HMI screen, and wherein the pressure sensor also functions to act as an over pressure safety switch which is triggered by the PLC logic when a pressure above the set safety limit is experienced in the water output line, and wherein the set safety limit pressure can be adjusted within the PLC logic to accommodate different water pumps as well as different hoses, and wherein the pressure safety limit can be adjusted from 1 pounds per square inch (psi) to 10000 psi,
- (c) An auxiliary water line (“jump jet” line or “pulse jet” line) and a jump jet valve, wherein the flow of water from the water pump to the jump jet line is controllable by the jump jet valve, wherein when the jump jet valve is in the OPEN position, water from a single piston in the pump is diverted back to the water tank, and wherein water from the single piston in the pump is diverted back to the water tank what is created is a pulse in the main water (the output hose).
