Economical tide/wave/swell/wind/solar powered high pressure fluid pump

Abstract

An apparatus for pumping and compressing fluids using floats which ride on the tides, swells and waves of the sea lowering an impeller by gravity when the tide falls and discharging fluid through back flow prevention valves above impeller when sea level rises for any reason. Pump will deliver sea water at any selected pressure determined by buoyancy of floats. Increasing buoyancy increases discharge pressure or lift or volume. Sea water pump is open to sea on inlet side when pumping sea water. Sea water seeks its own level rising to sea surface through impeller and back flow prevention valve. When pumping other fluids, pump is not open to sea and connects to fluid sources of supply. The pump is modified to prevent leakage to sea when pumping all other fluids. Fluid volume lift is increased by adding tidal range multipliers to pump and increasing float buoyancy making it possible to deliver greater volumes of fluids each time tide rises.

1 . A pump apparatus:
 which uses energy directly from tides, waves, swells, and wind which cause a float riding on the sea to move up ands down vertically and horizontally which is connected by cables to an impeller located in a pump housing which moves up and down in step with the float;   where the pump housing is attached to a foundation on the sea bed and is open to sea water on the inlet side of the impeller so when sea water level drops, impeller which has greater density than sea water sinks increasing resultant pressure on under side of impeller causing it to open and allow sea water to enter through an opening to sea and to pass through to top side of the impeller;   where when sea water level rises pressure on top side of impeller is higher causing it to close and as impeller rises, it lifts water upward toward a discharge back flow prevention valve which prevents higher pressure sea water from back flowing when sea level falls again;   where to opening to sea is covered with a strainer and filter to prevent intake of sea life and debris; where provisions have been made to use a solar powered motorized valve attached to discharge pipe on discharge side of discharge back flow valve to allow high pressure sea water to discharge inlet side of the impeller increasing sea water pressure and forcing any accumulated sea life or debris from the face of filter and screen;   that has zero energy costs because it does not use any purchased energy;   where the only costs prior to use are design, manufacturing and installation;   where the only costs after installation are operation and maintenance;   that doesn't require an onsite staff,   where maintenance crew requires no special education;   where discharge pressure and ability to do work can be increased simply by increasing float buoyancy by adding to length and/or width horizontally and not changing float height. that can: drive turbines to generate electricity on land, at sea, and below sea level; force sea, brackish, fresh waters through reverse osmosis membrane processes to generate potable water; force any other fluids needing cleansing of undesirable elements and foreign matter through reverse osmosis membrane processes producing fluids with desired purity; compress any gaseous fluids including air; deliver nutrient rich sea water to aquaculture farms; deliver nutrient sea water to off shore fisheries; create vacuums; deliver any fluids including colloids from one location to another for use or storage.   
   
   
       2 . A impeller in the method of  claim 1  comprising:
 a new use as a hinged multi-blade sliding fluid impeller with linked blades for heavy duty adjustable counterbalance back draft dampers used in the air conditioning industry;   a sturdy frame in horizontal position supporting impeller blades shown in partially open positions;   linkage ties the blades so they move together;   when axle rotates, dampers blades open and close;   adjustable counter balance allows for adjustment of sensitivity of blades to pressure changes which cause damper blades to open and close;   direction of flow of fluid is up as impeller moves vertically.   
   
   
       3 . A modified use of method of  claim 1  comprising:
 all details of  claim 1  except deleting opening to sea water with filter and strainer and replacing with an inlet back flow prevention valve so that any liquid and gaseous fluids can be pumped without leakage to sea water;   option one which is an addition of pulley spools on a common shaft with pulleys spools inside and outside of the pump housing eliminating the penetration by sliding cables and adding bearings with seals where shaft penetrates pump housing preventing leakage to sea water and outer pulley spools are connected to float by cables which rotate shaft whenever float rises and falls with sea water surface and shaft rotates pulley spools which are connected to impeller causing it to rise and fall whenever shaft rotates;   option two which is an addition of pulley spools supported outside pump housing eliminating penetration of pump housing by sliding cables by adding oscillating shafts that do not rotate and are attached to outer circumference of pulley spools with ball joints which flex when the pulley spools rotate creating an oscillating non-rotating motion which is transmitted through the pump housing to pulley spools on a shaft inside the pump housing connected with a ball joint which flexes when the pulley spools rotate shaft creating a rotating motion of pulley spool raising and lowering pump impeller;   option two where bearings with Seals are deleted and replaced with spherical oscillating bearings which do not rotate and flexible seals which allow the shafts to oscillate preventing leakage of sea water into pump housing.   
   
   
       4 . A modified use of method of  claim 1  comprising:
 combination with a tidal range multiplier using a lever arm for leverage;   where available tidal range is only ten feet and a twenty foot tidal range is desirable, a lever arm is used to convert ten foot tidal range to a twenty foot tidal range doubling volume of water lifted during each tide;   increasing the buoyancy of float(s) to lift additional weight of water and maintain desired lift or discharge pressure and desired discharge pressure or lift can be increased to any suitable pressure or level by adding more float volume;   
   
   
       5 . A modified use of method of  claim 1  comprising:
 combination with a tidal range multiplier using two different size pulleys for leverage:   where available tidal range is only ten feet and a twenty foot tidal range is desirable, with a tidal range multiplier using two different size pulleys for leverage:   are used to convert ten foot tidal range to a twenty foot tidal range doubling volume of water lifted during each tide;   increasing the buoyancy of float(s) to lift the additional weight of water and maintain desired lift or discharge pressure and desired discharge pressure or lift can be increased to any suitable pressure or level by adding more float volume.
