Abstract

Disclosed is a two cylinder water well pumping system which uses the wind as a primary driving force with an alternate electric motor drive for use when the wind force is not adequate. The wind drives a square wheel turbine which in turn drives a swash plate which provides a cam surface which then drives a semaphore assembly directly or indirectly connected to sucker cables in turn connected to two pistons carried, respectively, in two cylinder sleeves. The inclined angle of the swash plate alternately drives the pistons to pump water from a well into a storage tank also serving as a mainmast supporting said turbine. In an alterenative embodiment, an electric motor is connected to drive an osillatable bar on a mechancial relay. The oscillatable bar is connected by cables to the semaphore assembly, and may be disconnected from the semaphore assembly by a solenoid. In this embodiment, the sucker cables are connected to the rockable bar in the mechanical relay rather than to the semaphore assembly.

Dependent claims

A wind-electric water pumping system comprising:

a square wheel turbine having a specially constructed sails at each corner;
a mainmast providing support for said square wheel turbine;
said mainmast including a tank for storing pumped water;
a well casing extending into a well to provide protection to two alternatively operable pumping units encased in two parallel cylindrical sleeves;
a single sucker pipe connected to said two parallel cylindrical sleeves and guiding two sucker cables connected respectively to said pumping units at one end and to a semaphore assembly at an opposite end;
said semaphore assembly being located near the top of said mainmast and having wheels which ride on an angularly disposed swash plate connected to rotate with said turbine;
and
said sucker pipe being connected to said tank by a water inlet fitting;
whereby
when said turbine is rotated by a wind force, said swash plate is also rotated to drive said semaphore assembly which in turn alternately drives said sucker cables and said pumping units to alternately raise water through said respective cylinder sleeves with less energy expended per pumping unit cycle than would be expended by a single pumping unit designed to pump the same amount of water.
